Abstract

A slidable partition suspension system includes one or more roller assemblies integrally securable to a partition retention member. The partition retention member can be configured to hold and display a flexible, light-weight partition. The slidable partition suspension system can further include a track within which the one or more roller assemblies and the partition retention member are configured to slide. These components can provide the ability to provide a smooth gliding motion for partitions almost regardless of the rigidity and gauge of the partitions, while simultaneously securing the partitions in a desired configuration.

Description

SLIDABLE PARTITION SUSPENSION SYSTEMS

BACKGROUND OF THE INVENTION

The Field of the Invention This invention relates to apparatus, systems, and methods for suspending partitions from a ceiling, wall, or floor structure as a door, wall, covering, or other form of movable divider. Background and Relevant Art

Some recent architectural designs are now implementing synthetic, polymeric resins, which are used as partitions, walls, decor, etc., in offices and homes. In general, resin materials such as these are now popular compared with decorative cast or laminated glass materials, since resin materials can be manufactured to be more resilient and to have a similar transparent, translucent, or colored appearance as cast or laminated glass, but with less cost. Decorative resins can also provide more flexibility compared with glass at least in terms of color, degree of texture, gauge, weight, and impact resistance. Furthermore, decorative resins have a fairly wide utility since they can include a large variety of artistic colors, images and shapes.

As mentioned above, one particular use of decorative resins can be in a panel form, where the panel might be used as a door, wall, or other form of space divider. In the case of a door, there are many conventional ways to mount the door to a ceiling or wall. In particular, a manufacturer can attach the panel to a ceiling or wall using sliding-, hinged-, or pivoting-based hardware. Unfortunately, in some cases, mounting a resin panel as a moving partition in a way that allows the resin panel to display its aesthetic properties adequately can be difficult using conventional mounting hardware. In particular, conventional mounting hardware can be unsightly, too noticeable, or fail to provide an appropriate aesthetic for desired design environments. The unpleasant aesthetic of some conventional mounting hardware is often magnified when used with translucent, transparent, or other panels that magnify texture, light, color, and form. Thus, conventional mounting hardware may be unappealing to designers and architects seeking to obtain a certain aesthetic by using decorative architectural panels. Furthermore, many conventional hardware systems and options for mounting panels as moveable doors or partitions are designed for use with glass or other rigid panels. Indeed, some conventional hardware systems can fail to fully accommodate flexible partitions generally, as well as some of the unique challenges associated with such partitions. For example, some conventional sliding door hardware and frame systems are designed to accommodate glass and other rigid materials; as rigid materials, such as glass, provide significant structural stability. Conventional hardware may not adequately support flexible partitions or prevent them from bending, folding, or otherwise deforming during use. Additionally, some conventional mounting hardware generally does not provide much flexibility in terms of mounting style or arrangement without relatively complicated hardware and installation processes.

Another difficulty associated with some conventional partition and door hardware systems is they are often too heavy for use in many applications and locations. For example, some conventional sliding doors and hardware may weigh between 128 and 240 pounds per door. Therefore, a dual panel door may weight approximately 500 pounds. Thus, the weight alone of such conventional sliding panel systems may prevent use in many locations, such as, for example, rooms with suspended ceilings.

In addition to weight, the cost of many conventional sliding door systems can be prohibitive to a designer seeking a moveable divider. For instance, conventional sliding doors including decorative resin panels may cost several thousand dollars per door. The hardware alone for such systems can cost hundreds of dollars in some cases.

Furthermore, conventional hardware for mounting panels or other partitions as a moveable divider can often be too large in size or too complex in configuration for efficient use. For instance, some conventional hardware systems require considerable time and effort to assemble. Additionally, some conventional mounting hardware tends to result in an attachment that is fairly noisy when providing sliding or pivoting functions.

Accordingly, an advantage can be realized with conventional sliding door and partition hardware and systems. BRIEF SUMMARY OF THE INVENTION

One or more implementations of the present invention provides systems, components, and methods for suspending partitions as moveable dividers that are light weight, low cost, and easily installable. Additionally, implementations of the present invention provide systems, components, and methods for suspending flexible partitions that allow one to control light, add privacy, and divide rooms or other space. Furthermore, one or more implementations of the present invention provide systems for suspending partitions that allow the partitions to move or slide in an efficient manner without significantly detracting from the aesthetics provided by the partition. For example, one implementation of a slidable partition suspension system can include an upper retention member configured to support and receive an upper edge of a partition. The upper retention member can include a first end, an opposing second end, and a length extending therebetween. The slidable partition suspension system can also include one or more roller assemblies configured to be integrally secured to an end of the upper retention member via a snap-fit engagement. The slidable partition suspension system can additionally include a track configured to be mounted to a support surface. The one or more roller assemblies can be configured to couple the at least one upper retention member to the track and slide within the track.

Additionally, one implementation of a light-weight slidable partition suspension system can include a track having a pair of rails. The partition suspension system can also include an upper retention member secured to an upper edge of a flexible partition. The partition suspension system can further include a pair of roller assemblies secured to the distal ends of the upper retention member via a snap-fit engagement. The pair of roller assemblies can be positioned within the track and on the pair of rails. The upper retention member can extend from the pair of roller assemblies between the pair of rails.

In addition to the foregoing, a method of mounting a partition as a slidable divider can involve securing a track having a pair of rails to a support surface. The method can also involve disposing at least one roller assembly on the rails within the track. Additionally, the method can involve securing an upper edge of a partition to an upper retention member. Furthermore, the method can involve inserting the upper retention member upward into the track and between the rails. The method can yet further involve pressing the at least one roller assembly onto an end of the upper retention member.

Additional features and advantages of exemplary implementations of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of such exemplary implementations. The features and advantages of such implementations may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. These and other features will become more fully apparent from the following description and appended claims, or may be learned by the practice of such exemplary implementations as set forth hereinafter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention extends to systems, components, and methods for suspending partitions as moveable dividers that are light weight, low cost, and easily installable. Additionally, implementations of the present invention provide systems, components, and methods for suspending flexible partitions that allow one to control light, add privacy, and divide rooms or other space. Furthermore, one or more implementations of the present invention provide systems for suspending partitions that allow the partitions to move or slide in an efficient manner without significantly detracting from the aesthetics provided by the partition.

For example, slidable partition suspension systems of the present invention can be light weight. In particular, due to the use of light-weight partitions and light-weight hardware, as described in greater detail below, the total weight of slidable partition suspension systems of the present invention can be less than about 50 pounds per partition suspended. Thus, slidable partition suspension systems of one or more implementations can allow a user to suspend partitions from a wide variety of structures that may or may not be able to bear a conventional panel mounting system (which may weigh up to 240 pounds per door). For instance, slidable partition suspension systems of one or more implementations can allow a user to suspend slidable partitions from a suspended ceiling or dry wall panel.

Furthermore, partitions used with the components, systems, and methods of the present invention can be light-weight. For example, partitions of one or more implementations may include resin-based panels which are light-weight due to a small gauge or thickness. According to some implementations, light-weight, resin-based partitions, as contemplated by the present invention, can have a gauge of about one half inch (1/2") or less, such as for example, about one-fourth inch (1/4"), about one-eighth inch (1/8"), about one-sixteenth inch (1/16"), or less.

In addition to the foregoing, various components, systems, and methods described herein can allow a user to quickly and efficiently mount and dismount moveable partitions with relative ease. For instance, one or implementations include integratable roller assemblies. A user can mount a track with the integratable roller assemblies disposed therein. Then at a later time (for example, after the construction of door frame, ceiling, or wall has been completely finished), the user can mount a partition within the previously mounted track. In one implementation, for example, a user need only place an upper retention member within the track, and push the integratable roller assemblies onto the ends of the upper retention member. Thus, one or more implementations of the present invention provide a secure and reliable way to mount moveable partitions that also significantly reduces the time and labor needed to mount and/or dismount the partitions. Additionally, one will appreciate in light of the disclosure herein, that the integratable roller assemblies can enable the slidable partition suspension systems of the present invention to be quickly assembled, disassembled, and moved. For example, when a slidable partition suspension system is used as a room divider (e.g., Figure 2C), the integratable roller assemblies allow a user to quickly and easily dismount the partition(s) when full use of the room is necessary, and remount the partition(s) when desired. For instance, to dismount the partitions, a user can simply slide the integratable roller assemblies off of the upper retention member (without removing the track or the roller assemblies) and dismount the partition(s).

In addition to providing a secure, yet easily configurable, mount of moveable partitions, one or more implementations can help magnify the aesthetic features of a mounted partition or set of panels. For example, one or more implementations provide mounting hardware that reduces or eliminates the visibility of hardware. For example, one or more implementations include a hardware that can securely mount panels to a support structure without covering or otherwise obscuring any significant portion of the surfaces of the panels being displayed. Accordingly, a user can easily adapt implementations of the present invention to an environment of use and provide a number of secure mounting options.

As mentioned above, users (architects, designers, assemblers, etc.) may choose to use components of the present invention to mount moveable partitions, such as resin- based panels, because they can allow the partitions to be quickly and easily mounted with a reduced likelihood of damage, while also providing a pleasing aesthetic. As used herein, the terms "resin panel" and "resin-based panel" refer to panels comprising a substrate of one or more layers or sheets formed from any one of the following thermoplastic polymers (or alloys thereof). Specifically, such materials can include, but are not limited to, polyethylene terephthalate (PET), polyethylene terephthalate with glycol-modification (PETG), acrylonitrile butadiene-styrene (ABS), polyvinyl chloride (PVC), polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), polycarbonate (PC), styrene, polymethyl methacrylate (PMMA), polyolefms (low and high density polyethylene, polypropylene), thermoplastic polyurethane (TPU), cellulose-based polymers (cellulose acetate, cellulose butyrate or cellulose propionate), or the like. As a preliminary matter, implementations of the present invention are described herein primarily with reference to mounting panels, and particularly resin-based panels, as moveable partitions. One will appreciate, however, that a panel, particularly a resin- based panel, is only one type of "structure" which a user may mount as a moveable partition using the components, systems, and methods described herein. For example, a user can use implementations of the present invention to mount not only resin panels, as such, but also glass panels, to a given support structure. Furthermore, one will appreciate that a user can use various components and mounting assemblies described herein to mount other types of structures having different material compositions, such as objects comprising wood, stone, fiberglass, or the like, which may or may not exhibit primarily panel-like dimensions as described herein. Reference herein, therefore, to panels, or even resin panels, as such, is primarily for convenience in description.

Referring now to the Figures, Figure 1 illustrates a schematic diagram of a slidable partition suspension system 100 in accordance with an implementation of the present invention. As shown in Figure 1 , slidable partition suspension systems of the present invention can securely suspend or hang partitions, such as resin-based panels 102a and 102b, from a ceiling or other support structure, while also preserving an intended aesthetic for the partitions. For example, one or more slidable partition suspension systems of the present invention do not require frames or other hardware that can cover significant portions of the mounted partitions or otherwise detract from the aesthetic features of the partitions. For example, Figure 1 illustrates that the partitions (i.e., resin-based panels 102a,

102b) do not include a frame or other hardware covering or otherwise obscuring the sides of the resin-based panels 102a, 102b. In particular, Figure 1 illustrates that the only hardware that may be visible is one or more tracks (i.e., track 104a and 104b) and one or more lower retention members (i.e., members 106a and 106b). Furthermore, as explained in greater detail below, in some implementations, a user can mount the track(s) 104a, 104b within a wall or ceiling such that the track(s) is hidden from view. Additionally, in some implementations, the lower retention members 106a, 106b can be transparent or translucent to reduce their visibility. In alternative implementations, the lower retention members 106a, 106b can have a color/design corresponding with the color/design of the resin-based panels 102a, 102b. Thus, lower retention members 106a, 106b can blend in with the resin-based panels 102a, 102b and reduce their visibility.

As shown by Figure 1, the one or more partitions or resin-based panels 102a, 102b may slide or move the tracks 104a, 104b. Specifically, Figure 1 illustrates that a first resin-based panel 102a can slide within a first track 104a, and a second resin -based panel 102b can slide in a second tract 104b behind the first resin-based panel 102a. One will appreciate in light of the disclosure herein, that the slidable partition suspension system 100 can include one, two, three, four, or more partitions/panels depending upon the desired function and aesthetic.

To aid a user in sliding the partitions along the track(s) 104a, 104b, the slidable partition suspension system 100 can include a handle secured to one or more of the resin-based panels 102b. For example, Figure 1 illustrates a hanging handle 108 suspended from the top of one of the resin-based panel 102b, which a user can grip and pull on to slide the resin-based panel 102b along the track 104b. In alternative implementations, the handle may comprise a latch or other structure secured directly into the resin-based panel 102b.

One will appreciate in light of the disclosure herein, that slidable partition suspension systems of the present invention can be used as doors, walls, room dividers, window coverings, or almost any other type of partition or divider. For example, Figures 2A-2D illustrate various configuration in which a user can mount moveable partitions using the system(s), component(s), and methods of one or more implementations of the present invention.

For instance, Figure 2A illustrates a slidable partition suspension system 100a for use as an internally-suspended door — i.e., a "pocket door." In this implementation, the slidable partition suspension system 100a comprises a resin-based panel 102 and suspension apparatus suspended primarily inside a substrate of an internal wall opening (or internal door frame opening). In at least one implementation, for example, the slidable partition suspension system 100a includes a track mounted on the inside of the wall substrate, as well as extending inside and outside the door frame. The track thus allows a user to slide the door into a partly or completely concealed (or open) position within the wall, or to slide the door into a completely or partially closed position.

Figure 2B illustrates a slidable partition suspension system 100b functioning as a window covering. As shown in Figure 2B, the slidable partition suspension system 100b includes a track 104 mounted on a wall substrate. In this implementation, the partition 102c is always visible from at least one side of the wall on which the slidable partition suspension system 100b is mounted. As shown in Figure 2B, the partition 102c can comprise a slidable window covering. Thus, the slidable partition suspension system 100b can control the amount of light emitted into the room both by the type and translucency of partition, and by the position of the slidable partition suspension system 100b relative to the window. Furthermore, the partition 102c may comprise a flexible, light-weight partition. The user can slide the partition 102c along the track 104 in front of or away from a wall opening (e.g., window) as desired or necessary.

As previously mentioned, the partitions of the present invention can comprise resin-based panels, such as the panels 102, 102a, 102b shown in Figures 1 and 2A. One will appreciate from the following description and claims, however, that implementations of the present invention can be applied broadly not only to partitions formed from resin-based panels, such as polycarbonates, copolyesters, acrylics, or mixtures thereof, but also to non-resin based panels, such as those based partly or entirely from glass or glass composites. Furthermore, one will appreciate in light of the disclosure herein, that partitions as used herein can include both rigid and flexible partitions. Additionally, partitions used with the components, systems, and methods of the present invention can include flexible partitions comprising paper (or paper-style materials), non-woven fabric, film materials, woven fabric, MYLAR, flexible plastics, or other naturally occurring or synthetic materials, such as, for example, polyester fiber and recycled polyester fiber, or the like. For instance, Figure 2B illustrates that the partition 102c can comprise a collapsible, light-weight perforated partition.

In addition, Figure 2C illustrates another implementation of a slidable partition suspension system 100c, where a plurality of partitions 102 is suspended directly to an overhead/ceiling substrate as a room divider. In at least one implementation, this configuration can allow for multiple partitions. For example, a user can suspend a plurality of partitions in any combination of fixed or slidable mountings. The user can then suspend many or most of the partitions in a fixed position to resemble a stationary wall, and then subsequently suspend fewer than all of the partitions in more mobile positions as one or more sliding dividers.

In another implementation, the user can suspend all of the partitions as slidable partitions, such that the user can move any or all of the partitions in a door or divider capacity. In some implementations, a user can suspend each of the partitions in a single track 104. In additional implementations, the user can suspend each of the partitions from separate tracks 104 thereby allowing the partitions 102 to bypass each other.

Figure 2D illustrates still another implementation of a slidable partition suspension system 10Od, in which the user has mounted the track 104 within a door frame as a "bypassing door." In this implementation, the user has not mounted the track 104 inside the wall, but instead has mounted the track 104 primarily (or exclusively) within the visible part of the door frame. Thus, upon suspending the partitions 102 in the appropriate track(s), the user can move any or both of the partitions 102 along the corresponding tracks as doors. In contrast with the pocket door 100a implementation of Figure 2A, the user of the bypassing door lOOd would not necessarily conceal the track 104 within a wall.

As illustrated in each of the Figures 2A-2D, the slidable partition suspension systems lOO(a-d) of the present invention can suspend partitions from a support structure. In other words, the bottom edge of each partition 102 can be suspended from a floor or other lower surface so each partition 102 is hanging. Suspending the partitions 102 can reduce the hardware necessary for each slidable partition suspension system lOO(a-d), and thus, reduce cost and assembly time. Furthermore, a user can suspend the partitions and eliminate any track or connection to a floor or other lower surface. Thus, a user can quickly assemble, disassemble, and move the slidable partition suspension systems lOO(a-d) of one or more implementations of the present invention. Additionally, the suspension of the partitions 102 can provide a design space with a desired aesthetic.

Figures 3-4 and the corresponding text illustrate or describe a number of details and features of a slidable partition suspension system lOOe in accordance with an implementation of the present invention. For example, Figure 3 illustrates an exploded- view of a slidable partition suspension system 10Oe, and Figure 4 illustrates an assembled, partial cross-sectional end-view of the slidable partition suspension system 100e ofFigure 3.

As shown in Figures 3 and 4, an upper retention member 110 and a lower retention member 106 can support the partition 102. As described in greater detail below, the upper retention member 110 and the lower retention member 106 can support and help maintain a flexible partition 102 in a desired configuration. For example, the upper retention member 110 and the lower retention member 106 can help prevent a flexible partition from wrinkling, bending, or otherwise deforming.

The upper retention member 110 and the lower retention member 106 can stabilize a partition 102 almost regardless of its gauge. For example, partitions formed from resin panels are typically manufactured to vary in gauge from as thin as about one- eighth inch (1/8") or one quarter inch (1/4"), or thinner, to as thick as about one and one-half inches (1 1/2") to about two inches (2"), or thicker, depending on the end- user's designs. In general, thicker gauges tend to be sturdier and more expensive than thinner gauges with respect to conventional partitions and panels. In accordance with the present invention, however, the upper retention member 110 and the lower retention member 106 can provide sufficient stability to thinner partition gauges, such as anywhere from about one-sixteenth inch (1/16") to about three-eighths inch (3/8") or thicker. In particular, some implementations can allow use of thinner, potentially more cost-effective, partitions 102 without sacrificing rigidity or deflection resistance.

Similarly, the upper retention member 110 and the lower retention member 106 can stabilize a partition 102 almost regardless of its rigidity or flexibility. For instance, the upper retention member 110 and the lower retention member 106 can hold and maintain a flexible partition in an extended or other desired configuration. Additionally, the upper retention member 110 and the lower retention member 106 can provide the stability necessary to allow a user to slide a flexible partition 102 along the track 104.

The lower retention member 106 can serve as a weight to hold a flexible partition 102 in a fully extended configuration. The lower retention member 106 can include various features to hold or secure the bottom edge of the partition 102. For example, as shown in Figure 3, the lower member 106 can include cap members 112. The cap members 112 can act as end caps for the lower retention member 106. Additionally, the cap members 112 can help secure the partition 102 to the lower retention member 106. For example, each partition 102 can include a pair of notches 114 within which portions of the cap members 112 can extend. The cap members can lock the bottom edge of the partition 102 to the lower retention member 106. As discussed herein, the slidable partition suspension systems of the present invention can include integratable roller assemblies. For example, Figure 3 illustrates that the slidable partition suspension system lOOe can include two integratable roller assemblies 116. The integratable roller assemblies 116 can include can secure the upper retention member 110 to the track 104, and allow the upper retention member 110 and connected partition 102 to slide or otherwise move along the track 104.

The integratable roller assembles 116 can include features that allow a user to snap-fit them onto the ends of the upper retention member 110. In other words, the integratable roller assemblies 116 can have a configuration that allows a user to connect the integratable roller assemblies 116 to the ends of the upper retention member 110 by simply pressing the integratable roller assemblies 116 and the ends of the upper retention member 110 together. In particular, when a user presses the integratable roller assemblies 116 and the ends of the upper retention member 110 together, the integratable roller assemblies 116 can automatically lock to the upper retention member 110. Such a snap-fit configuration can allow a user to easily mount and dismount partitions 102 to the track 104 with relative ease.

As shown by Figure 3, in some implementations, each integratable roller assembly 116 can include a catch 118 to facilitate the snap-fit configuration. As explained in greater detail below, a user can secure the catch 118 to the upper retention member 110. Then when the user presses the integratable roller assembly 116 against the upper retention member 110, features on the integratable roller assemblies 116 can engage and lock to corresponding features on the catch 118.

Each roller assembly 116 can function as an end cap to the upper retention member 110, and can help secure the partition 102 to the upper retention member 110. Additionally, each roller assembly 116 can include one or more pairs of rollers 120. Each pair of rollers 120 can allow the roller assemblies 116 and upper retention member 110 to slide within the track 104. In particular, as shown by Figure 4, the track 104 can include a set of rails 122. The rails 122 can extend from the outer walls of the track 104 into the body of the track 104. The upper retention member 110 can fit between the rails 122, and the rollers 120 can ride on top of the rails 122. Thus, the roller assemblies 116 can hold the upper retention member 110 and slide within the track 104. In particular, according to some implementations, the rollers 120 of the roller assembly 116 can have a taper as shown in Figure 4. In such embodiments, the rails 122 of the track can include a correspondingly angled configuration. The tapered configuration of the rollers 120 and the rails 122 can help reduce noise as the rollers 120 move along the track 104. According to additional implementations, however, the rollers 120 and rails 122 can have a square configuration.

In either case, the roller assemblies 116 can reduce noise produced as a partition 102 is slid along the track 104. For example, according to some implementations, the rollers 120 and the body of the roller assemblies 116 can comprise dissimilar materials. In particular, the rollers 120 and the body of the roller assemblies 116 can comprise materials with differing coefficients of friction to help reduce the creation of noise. For instance, the rollers 120 can comprise a natural or synthetic rubber and the body of the roller assemblies 116 can comprise polyoxymethylene. According to additional implementations, the rollers 120 and body of the roller assembly 116 can comprise dissimilar polymers. In yet further implementations, the rollers 120 and body of the roller assembly 116 can comprise similar or identical materials.

To help maintain the roller assemblies 116 within the track 104, the track 104 of the slidable partition suspension system 100 can include one or more end caps 124. For example, as shown in Figure 3, a user can secure the end cap 124 to the track 104 via one or more fasteners 126. According to at least one implementation of the present invention, the fasteners 126 can comprise set screws. According to one or more additional implementations of the present invention, the end caps 124 can have a snap fit engagement with the track 104.

In either case, the end cap 124 can close off the track 104 to help ensure that the roller assemblies 116 and upper retention member 110 are not pulled out of the track 104 by a user when manipulating a slidable partition 102. Additionally, the end cap 124 can include one or more bumpers 128. The bumper 128 can provide a cushioning and noise dampening function upon contact with a sliding roller assembly 116. The bumpers 128 can comprise a resilient material, such as for example, a polymer, or a natural or synthetic rubber.

In at least implementation, an end of the track 104 may abut a wall or other surface. In such cases, a user may not use an end cap 124. In addition to end caps 124, or in place thereof, the slidable partition suspension system lOOe can include one or more stoppers 130. A user can place a stopper 130 within the track 104 to prevent the partition 102 from sliding beyond a desired point. For example, the user may desire to place a fixed partition at one end of the track 104. In order to ensure that the moveable partition 102 does not slide into or beyond the fixed partition, the user can install a stopper 130. In particular, the user can secure the stopper 130 within the track 104 using a fastener 126. Similar to the end cap 124, the stopper 130 can include a bumper 128 that provides a cushioning and noise dampening function.

According to at least one implementation of the present invention, the slidable partition suspension system lOOe can also include engagement members 132a, 132b. For example, Figure 3 illustrates that a user can secure one or more engagement members 132a, 132b to each upper retention member 110. The engagement member 132a, 132b can hold a handle 108 (Figure 1). In particular, as shown in Figure 4, a user can suspend a cable 134 from the engagement member 132a, 132b. A user can in turn secure a handle 108 to an opposing end of the cable 134. A user can thus use the handle 108 to pull or slide a suspended partition 102 along the track 104.

Additionally, each engagement member 132a, 132b can also serve as a catch mechanism for hooking or linking multiple partitions 102 together. For example in at least one implementation of the present invention including two or more suspended partitions 102 (such as slidable partition suspension systems 100c and lOOd shown in Figures 2C and 2D) each engagement member 132a, 132b can link to an engagement member 132 on an adjacent suspended partition 102. Thus, a user can move or slide multiple suspended partitions 102 via a single handle 108. One will appreciate in light of the disclosure herein, the engagement members 132a, 132b can comprise right- handed engagement members 132a and left-handed engagement members 132b as shown in Figure 3. Each right-handed engagement member 132a can link with a left- handed engagement member 132b on an adjacent suspended partition 102. Additionally each engagement member 132a, 132b can include a bumper 128 that provides a cushioning and noise dampening function.

As mentioned previously, a user can mount each track 104, either directly or indirectly, to a support surface (see Figures 2A-2D for some exemplary implementations). For example, according to some implementations, a user can mount the track 104 directly to a support surface via one or more fasteners. For instance, the user can secure fasteners through the upper surface of the track 104 into a ceiling or other overhead structure, such as shown, for instance, in Figure 2C. Alternatively, the user can secure fasteners through a side wall of the track 104 into a wall or other structure, such as shown, for example, in Figure 2B.

According to additional implementations, a user can secure each track 104 to a support structure via a mounting assembly 136. As shown by Figure 3, the mounting assembly 136 can comprise a linking member 138 and a mounting extrusion 140. In particular, a user can secure the mounting extrusion 140 to the support structure via one or more fasteners. After which the user can slide an upper flange of the linking member 138 within a channel of the mounting extrusion 140. Similarly, a user can slide a channel in the track 104 around a flange of the linking member 138. Thus, the linking member 138 can secure the track 104 to the mounting extrusion 140.

Figure 4 illustrates the slidable partition suspension system lOOe secured to a support structure (ceiling 103) via a mounting assembly 136. As shown by Figure 4, flanges of the linking member 138 can extend into corresponding channels of the track 104 and the mounting extrusion 140. In alternative implementations, the linking member 138 can include channels which receive corresponding flanges on the track 104 and/or mounting extrusion 140. In any event, the mounting assembly 136 can serve as an intermediate hardware piece for securing the slidable partition suspension system lOOe to a support structure.

One will appreciate in light of the disclosure herein that the mounting assembly 136 can allow for easy mounting and dismounting of the track 104 and the slidable partition suspension system 10Oe. In particular, the mounting assembly 136 can enable a slidable partition system to be semi-permanent. For example, when the slidable partition suspension system lOOe is used as a room divider (e.g., Figure 2C), the mounting assembly 136 allows a user to quickly and easily dismount the slidable suspension system lOOe when full use of the room is necessary, and remount the slidable suspension system lOOe when desired. In particular, the mounting assembly 136 can allow a user to mount and dismount the track 104 from a support structure 103 without having to remove any hardware or fasteners from the support structure 103. For instance, to dismount the slidable partition suspension system lOOes, a user can simply slide the linking member 138 out of the channels of the mounting extrusion 140 and track 104.

Figure 5 illustrates a number of the details and features of the upper retention member 110 and the integratable roller assembly 116. As mentioned previously, the upper retention member 110 can hold an upper edge of a partition 102. For example, Figure 5 illustrates that the upper retention member 110 can include a mounting slot 142 within which a user can secure a partition 102. According to some implementations, a user can secure a partition 102 within the mounting slot 142 via a fastener, such as, for example, screws, double-sided hook and loop fasteners (such as VELCRO), tape, or an adhesive.

The upper retention member 110 can further include a number of features to aid in receiving and securing an integratable roller assembly 116 thereto. For example, Figure 5 illustrates that according to some implementations at least a portion the roller assembly 116 can slide onto the upper retention member 110. In particular, the upper retention member 110 can include a channel 144 and a protrusion 148. The protrusion 148 can engage a corresponding slot 150 within the roller assembly 116.

As shown in Figure 5, both the protrusion 148 and the corresponding slot 150 can have a t-shape. In particular, the protrusion 148 can comprise a male component and the corresponding slot 150 can comprise a female component configured to receive the protrusion 148. In other implementations, the upper retention member 110 can comprise a female component, with a t-shape or otherwise, and the roller assembly 116 can include a corresponding male component instead of a slot 150. The protrusion 148 and the slot 150 can have an interference or friction fit so that a user cannot pull the roller assembly 116 off of the upper retention member 110 with a nominal force. In additional implementations, the protrusion 148 and the slot 150 can have a snap-fit engagement.

A user can secure the catch 118 to the upper retention member 110. The catch 118 can help ensure that the roller assembly 116 is not inadvertently pulled off of the upper retention member 110. For example, the catch can include a slot 152 with a shape corresponding to the protrusion 148 of the upper retention member 110. A user can slide the slot 152 of the catch 118 over the protrusion 148. The user can then slide the catch 118 along the protrusion 148 of the upper retention member 110 and lock the catch 118 in place by securing a fastener 154 within recess 156. The fastener 154 can prevent movement of the catch 118 relative to the upper retention member 110.

With the catch 118 secured to the upper retention member 110, a user can insert the protrusion 148 of the upper retention member 110 within the corresponding slot 150 of the roller assembly 116. By so doing, a clip or spring tap 158 on the roller assembly 116 may engage a groove 160 on the catch 118. Once within the groove 160 of the catch 118, the clip 158 can secure the roller assembly 116 to the catch 118, and thus, the upper retention member 110. Thus, the catch 118 and clip 158 can prevent the roller assembly 116 from being inadvertently released from the upper retention member 110. In other words, the clip 158 and catch 118 can provide the snap-fit engagement between the upper retention member 110 and the roller assemblies 116. Additionally, the roller assembly 116 can further include a securing member 162 that can slide within the channel 144 of the upper retention member 110. One will appreciate that the securing member 162 and the slot of the roller assembly 116 can bear the weight of the upper retention member 110 and any partition 102 secured thereto. In some implementations, the securing member 162 can have a snap-fit engagement with the channel 144 of the upper retention member 110.

The roller assemblies 116 can integrate with the upper retention member 110 with a snap-fit configuration or using any number of different mechanisms. One will appreciate that the implementation shown in Figure 5 is one exemplary configuration for a roller assembly. In any event, the integratable roller assemblies 116 of the present invention can simplify installation of a moveable partition 102. For instance, as shown by Figure 6, the integratable roller assemblies 116 can allow a user to first mount the track 104, integratable roller assemblies 116, and any end caps 124 or stoppers 118. Then at a later time (for example after the construction of door frame, ceiling, or wall has been completely finished), a user can mount the partition 102 within the previously mounted track 104. In particular, as shown by the vertical arrows in Figure 6, a user can insert the upper retention member 110 and the partition 102 into the track 104 (from the bottom). As shown by the horizontal arrows of Figure 6, the user can then push the integratable roller assemblies 116 onto the ends of the upper retention member 110 and the catches 118, locking the upper retention member 110 and partition 102 to the track 104,.

One will appreciate in light of the disclosure herein that the ability to mount partitions 102 to the track 104 from the bottom or underside can provide many benefits. For example, in some design environments there may not be sufficient space to insert the upper retention member 110 and associated partition 102 into the end of a track 104. In other design environments, a user may need to mount the track 104 before the rest of the design space is completed. In such cases, the ability to later add the partition 102 to the track 104 can prevent damage to the partition 102 during the finishing of the design space.

In any event, the integratable roller assemblies 116 and upper retention member 110 can enable a user to quickly assemble, disassemble, and move the slidable partition suspension systems 100 of the present invention. For example, when the slidable partition suspension system 100 is used as a room divider (e.g., Figure 2C), the integratable roller assemblies 116 and upper retention member 110 can allow a user to quickly and easily dismount the slidable suspension system 100. For instance, to dismount the partition 102, a user can simply slide the integratable roller assemblies 116 off of the upper retention member 110 (without removing the track 104 or the roller assemblies 116) and remove the partition 102.

As mentioned previously, the lower retention member 106 can include various features to hold or secure the bottom edge of a partition 102. For example, a user can secure the bottom edge of a partition 102 within a mounting channel 170 of the lower retention member 106. According to some implementations, a user can secure a partition 102 within the mounting slot 170 via a fastener, such as for example, screws, double-sided VELCRO or tape, or an adhesive.

Additionally, the lower member 106 can include cap members 112. The cap members 112 can help secure the partition 102 to the lower retention member 106. As shown in Figure 7, the cap member 112 can include a first flange 164 configured to engage and hold the cap member 112 within a mounting slot 166 of the lower retention member 106. Furthermore, the cap member 112 can include a securing flange 168. A user can slide the securing flange 168 into a notch 114 of a partition 102 (see e.g., Figure 3). Thus, the combination of the flanges 164, 168 can ensure that a partition 102 is securely mounted within a mounting channel 170 of the lower retention member 106. In some implementations, the flanges 164, 168 can have a snap fit engagement with the partition 102 and lower retention member 106.

A user can choose a cap member 112 based on the type of partition being suspended. For example, with partitions formed from resin-based panels and materials, the cap member 112 can include a first flange 168 configured to engage a notch 114 within the resin-based panel. In alternative implementations where a more flexible partition is used, such as partition 102c shown in Figure 2B, the cap member 112 may not include a first flange 168.

Implementations of the present invention can also include methods of assembling and mounting slidable partitions to a support structure. The following describes at least one implementation of a method of mounting a slidable partition suspension system 100 to a support structure with reference to the components and diagrams of Figures 1 through 7. Of course, as a preliminary matter, one of ordinary skill in the art will recognize that the methods explained in detail herein can be modified to install a wide variety of configurations using one or more components of the present invention. For example, various acts of the method described can be omitted or expanded, and the order of the various acts of the method described can be altered as desired.

Thus, according to one method of the present invention, a user can secure at least one track 104 having a pair of rails 122 to a support structure 103. For example, the user can secure a surface of the track 104 to a support surface 103 using one or more fasteners. One will appreciate in light of the disclosure herein that the user can select an appropriate fastener based on the type of support structure (i.e., wood, concrete, drywall etc.). Alternatively, the user can secure the track 104 to a support surface 103 using a mounting assembly 136. In particular, the user can secure a mounting extrusion 140 to a support surface 103 via one or more fasteners. The user can then insert a linking member 138 within a channel of the mounting extrusion 140. At this point the user can slide a channel of the track 104 over a flange of the linking member 138.

Once the track 104 is secured to a support surface 103, or even before if desired, the user can dispose one or more roller assemblies 116 within the track 104. For example, the user can insert the roller assemblies 116 into an end of the track 104. In particular, the user can position the rollers 120 of the roller assembly 116 on the rails 122 of the track 104. In at least some implementations, the body of the roller assembly 116 can extend between the rails 122 of the track 104.

The method can also include securing an upper edge of a partition 102 to an upper retention member 110. For example, the user can slide the upper edge of the partition 102 into a mounting slot 142 of the upper retention member 110. The user can then fasten the partition 102 within the mounting slot 142 using one or more of a screw, double-sided hook and loop fasteners (such as VELCRO), tape, or an adhesive.

Additionally, the method can include inserting the upper retention member 110 upward into the track 104 and between the rails 122. For example, when the track 104 is mounted to a support surface 103, the user can slide the upper retention member 110 upward into the track 104 until a protrusion 148 of the upper retention member 110 is between the rails 122 of the track 104.

The method can then include pressing the at least one roller assembly 116 onto an end of the upper retention member 110. For instance, the user can slide a slot 150 in the roller assembly 116 over the protrusion 148 of the upper retention member 110. By so doing, the user can cause one or more engagement features of the roller assembly 116 to snap onto or lock themselves to the upper retention member 110. For example, a spring tab 158 on the roller assembly 116 can snap over a catch 118 secured to the retention member 110. Alternatively, a spring tab on the roller assembly 116 can snap into a hole or channel on the retention member 110. Accordingly, Figures 1-7 and the corresponding text, therefore, specifically show, describe, or otherwise provide a number of systems, components, apparatus, and methods for efficiently mounting, moving, or holding a slidable partition. In addition to these, however, one will appreciate that implementations of the present invention can further include additional components for other functionality of a given partition system. For example, implementations of the present invention can also include one or more edge locks for securing bypassing partitions. One will appreciate, therefore, that the components described herein can be simple to assemble. Additionally, components of the present invention can provide an elegant interface that can also allow any type of partition (including light weight and flexible partitions) to be used as a door or other slidable divider. Furthermore, components and systems of the present invention can slide relative to a wall with efficiency, lack of noise, and with excellent aesthetic characteristics.

The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. Thus, the described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
