Description

TITLE

MODULAR RACK WITH ADJUSTABLE BRACKET

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is based upon and claims the benefit under 35 USC 119(e) of prior U.S. Provisional Patent Application No. 62/839,466, filed April 26, 2019, and prior U.S. Provisional Patent Application No. 62/945,643, filed December 9, 2019, in the U.S. Patent and Trademark Office, the entire contents of all of which are incorporated herein by reference.

BACKGROUND

[0002] Existing free-standing gun racks fill up available floor space by storing the rifles in a single row vertically parallel to each other, or as it is common with mounted horizontal rack designs require a wall or room fixture to be attached to, hence limiting the number of gun racks that can be installed to available walls and room fixtures.

[0003] A limiting factor with existing fixed horizontal gun racks is that the rack is a fixture, and in addition there is a fixed distance between slots where the firearms are stored, not allowing the user to change the spacing between the slots to accommodate for different attachments such as scopes or magazines, hence limiting a capacity of the number of firearms that can be stored on a rack.

[0004] In addition to the capacity shortcomings, even in case of a free-standing rack, such a rack does not allow for re-positioning of a fully loaded rack without requiring the user to remove the stored articles from the rack first before being able to safely move the rack. In addition to that, such racks are designed to be assembled once and not intended for frequent disassembly, hence making the rack difficult to transport.

The support column 101 may include an elongated front side 206 and a channel 400 on the elongated front side of the column 101. A plurality of brackets 102 may be movably coupled to the channel 400 of the column 101. A bracket 102 among the brackets 102 is fastentable to be stationary and releasable to be moveable up and down along the channel 400. A position of the bracket along the channel 400 may be adjusted by releasing the bracket at first position to move the bracket along the channel 400 and fastening the bracket at another second position along the channel 400, when the rack 100 is positioned with the elongated side being vertical to a surface, for example, a floor, for use.

[0020] FIG. 1 B is a diagram of the bracket 102 of the rack 100 in FIG. 1 A storing an elongated item, according to an example of the present disclosure. The bracket 102 may be a mounting bracket assembly including a bracket plate 104 and a protrusion 106 extending from a front side 108 of the bracket plate 104. The protrusion 106 is disposed to be angled upward or to have reverse tilt in relation to a front of the rack 100 so that that the protrusion 106 can stably support an article resting on the protraction 106. The shape of the bracket plate 104 may be

rectangular. However, the shape of the bracket plate 104 is not limited to the rectangular shape, and the shape of the bracket plate 104 may be elliptical or other shapes to accommodate a protrusion 106. The bracket plate 104 may be a single bracket plate or a plurality of bracket plates.

[0021] A single protrusion 106 may be coupled to the bracket plate 104 in form of a shelf. The protrusion 106 may be a plurality of protrusions, for example, a pair of protrusions 106A, 106B coupled to the front side 108 of the bracket plate 104 at corresponding positions away from a center of the bracket plate 104 and towards corresponding side edges of the bracket plate 104. For example, the protrusions 106 are coupled to the bracket plate 104 closer to side edges of the bracket plate 104 and at positions to be in a symmetrical positional relationship to the center of the bracket plate 104. The protrusion 106 may be in form of a dowel coupled to the front side 108 of the bracket plate 104. The protrusion 106 may be hook shaped to support an article.

The coupling of the protrusion 106 to the bracket plate 104 may be a screw or other fastener to contact and put pressure on the protrusion, for example, by threading through at 490 at a side 490 of the bracket plate 104. The bracket plate 104 and the protrusion 106 may be made of wood, resin or plastic and coupled to each other, or formed as a single piece by resin or plastic injection molding, metal, or of other material, including printing material usable by 3D printing machines.

[0022] FIGS. 2A and 2B are diagrams of a side view of the rack 100 in FIG. 1A illustrating an angled position of the support column 101 relative to the baseplate 103, according to an example of the present disclosure. The support column 101 may have an elongated rectangular shape, having a front side 206 and a backside 208. Referring to FIG. 2A, the support column 101 may be coupled to the baseplate 103 at an angle Q1 200 to allow for a secure resting position of the items placed on the protrusion 106 extending from the bracket 102 while at the same time maintaining the balance and stability of the rack 100 by preventing the rack 100 tilting forward, or tipping. For example, the angle Q1 200 formed between the support column 101 and the baseplate 103 may be approximately 97°.

[0023] Referring to FIG. 2B, the baseplate 103 may be a baseplate assembly including a base part 220, a support part 224, and a base column 226. The support column 101 may be referred to as a long column and the base column 226 may be referred to as a short column. The support part 224 may have a rectangular cuboid shape. One side of the support part 224 may be angled to be capable of being positioned to abut the short column 226. The support part 224 and the short column 226 have corresponding angled sides 210, 212, respectively, to form a tilting angle Q3 230. When the angle Q1 200 formed between a combined column assembly 105 including the long column 101 and the short column 226, and the base part 202 is

approximately 97°, then an angle Q2 222 formed between the support part 224 and the base part 220 may be approximately 90° and corresponding angled sides of the support part 224 and the short column 226 indicated as Q3 230 are approximately 7°, so that a center of gravity is shifted towards a middle of the baseplate 103 to provide an optimal freestanding stability for the rack 100.

[0024] Referring to FIG. 2B, depending on the distance 231 of the short column 226 from a center of the baseplate 103 to a front of the baseplate short extension 358 of the baseplate 103, an overall length 232 of the support column 101 and the short column 226, and an overall length 233 of the baseplate 103, the angle Q1 200 can be between 90° to 100° , with the corresponding angled sides of the support part 224 and the short column 226 indicated as Q3 230 to be between 0° to 10° respectively, to provide an optimal freestanding stability for the rack 100 . In FIG. 2B, Q3 230 corresponds to a range of a center of gravity of the column assembly 105 relative to a position of the column assembly 105 on the baseplate 103 from a center of the baseplate 103 toward a front of the baseplate 103, such that as the position of the column assembly 105 is moved towards the front of the baseplate 103, the angle Q1 200 can be increased while the angel Q3 230 also increases to achieve stability for the rack 100.

[0025] The short column 226 may have an angled bottom side 210 corresponding to the tilting angle Q3 230 to cause the short column 226 to have a corresponding angled front side 212 facing a front of the rack 100 where items are positioned to rest on the protrusion 106. The tilting angle Q3 230 is not limited to being formed by the corresponding angled sides 210 and 212, and may be provided where a back side 214 of the short column 226 is angled to meet the angled front side 212 of the short column 226.

[0026] FIG. 3A is a bottom view of a baseplate, according to an example of the present disclosure. Referring to FIG. 3A, the baseplate 103 as a baseplate assembly may include baseplate leg stands 350, a baseplate roller 354, a baseplate short extension 358, a baseplate long extension 362 which has a longer width than a width of the baseplate short extension 358. As an example, the baseplate leg stands 350 are coupled to areas on bottom sides 364A, 364B of the baseplate short extension 358 and the long extension 362, respectively. As an example, the baseplate roller 354 is a plurality of baseplate rollers 354 coupled to areas on a bottom side 366 of the base part 220. The height of the baseplate leg stands 350 may be adjustable to be lowered so that the baseplate rollers 354 can be engaged by contacting a surface such as a floor to make the rack 100 mobile to be moved in any direction. Once the rack 100 has been moved into the desired location, the height of the leg stands 350 may be adjusted to be increased to disengage by separating from the surface the baseplate rollers 354 by separating the baseplate rollers 354 from the surface to make the rack 100 stationary on the baseplate leg stands 350. The combination of baseplate leg stands 350 and baseplate rollers 354 to engage and disengage movement of the rack 100 provide a stable rack while in the stationary position.

[0027] The baseplate short extension 358 and the baseplate long extension 362 are coupled to the front and back of the base part 220, respectively, of the baseplate 103. Widths of the baseplate short and long extensions 358, 362 may be longer by at least 1x to 5x than a width of the plate part 220 of the baseplate 103. The different width sizes of the baseplate short and long extensions 358, and 362 may provide additional stability to the rack to prevent it from tilting, or tipping, sideways. The baseplate rollers 354 may be ball bearing roller balls that are coupled to the bottom side 366 of the base part 220 and may be engaged or disengaged to contact a surface by lowering or raising the rack by adjusting the height of the baseplate leg stands 350, so that the rack can be moved in the desired direction. According to another example to support mobility of the rack 100, wheels with breaks may be coupled to the bottom side 366 of the baseplate 103.

[0028] FIG. 3B is a diagram illustrating coupling of the baseplate in FIG. 3A, according to an example of the present disclosure. Referring to FIG. 3B, the baseplate 103 as a baseplate assembly may include a baseplate vertical joint (V-joint) 370, a baseplate anchor 372, and a column support coupler 374, for example, a screw. The support part 224 is positioned behind, or adjacent to a backside 214, of the short column 226 and fastened to the short column 226 via two column support couplers 374. The short column 226 is held in place on the base part 220 via the baseplate V-joint 370. The baseplate V-joint 370 may be embedded in and protrude from the plate part 220 of the baseplate 103 to be received by, or inserted into, a

correspondingly shaped v-joint groove 382 in the short column 226. A plurality of v-joints 370 may be provided, for example, a pair, or a single wide v-joint 370 may be provided.

[0029] Referring to Fig. 3B, the support part 224 may be coupled to the base part 220 of the baseplate 103 via the baseplate anchor 372. The baseplate anchor 372 with an anchor post 378 may be embedded in and protrude from the plate part 220 of the baseplate 103 to be received by, or inserted into, a correspondingly shaped anchor groove 386. The anchor post 378 may include a threaded portion to accept an anchor post coupler 380, for example, a screw, through the short column 226. The baseplate anchor 372 may be a single baseplate anchor.

[0030] FIG. 4A is a diagram of the bracket 102 mounted on the rack 100, according to an example of the present disclosure. And FIG. 4B is a diagram of an adjusting device for the bracket in FIG. 4A, according to an example of the present is disclosure. Referring to Fig. 4A, the support column 101 may include an elongated front side 206 and a channel 400 on the elongated front side 206 of the column 101. A plurality of brackets 102 may be movably coupled to the channel 400 of the column 101. A bracket 102 among the brackets 102 is moveable up and down along the channel 400 and capable of being fastened along the channel 400 to prevent sliding of the bracket 102 when the rack 100 is oriented vertically for use.

[0031] Referring to FIG. 4A, the channel 400 may be formed as a groove on the elongated front side 206 of the support column 101. Referring to Fig. 4B, a guide 407 having a T-bar shape may be embedded in the groove 400. The T-bar guide 407 may be fastened to the support column 101 by a coupler 408, for example, a screw, nail, glue or other coupling mechanisms. However, the guide 407 is not limited to the T-bar shape, but the guide 407 may be any shape to guide movement of a bracket 102.

[0032] Referring to FIG. 4A, for example a column cap 480 may be accommodated on top of the column 101 by a v-joint 482 in a corresponding groove 484 shaped in accordance with the shape of the v-join 482. Another way to add or remove the bracket 102 to and from the rack 100 is by removing the column cap 480 from top of the support column 101 and inserting by sliding the bracket 102’s guide T-Nut 454 into the T-bar guide 407.

[0033] Referring to FIG. 4B, the bracket 102 may be coupled to the T-bar guide 407 through an adjusting device. The adjusting device may include a guide coupler 450, for example, as a guide screw, and a corresponding nut, for example, a guide T-nut 454 fittingly insertable in the T-bar guide 407. The guide T-nut 454 may be moveable to travel inside the T-bar guide 407. A width of the T-bar guide 407 is configured to be sufficiently larger than a width of a T shaped head of the T-nut to allow for movement of the T-nut 454, while preventing, or blocking by interior sides of the T-bar guide 407, rotation of the T-nut 454 inside the T-bar guide 407, which prevents the guide T-nut 454 inserted in the T shaped bar to rotate to loosen. A guide screw washer 456 corresponding to the guide screw 450 and a guide nut washer 458 corresponding to the guide T-nut 454 may be provided. By tightening the guide screw 450 and the guide T-nut 454, pressure is exerted on the guide screw washer 456. A depth of the T-bar guide 407 corresponds to a length of the guide T-nut 454 to allow for the guide screw washer 456 to bend and press against the bracket plate 104 when the guide screw 450 is tightened.

[0034] For example, the guide screw washer 456 is made of polyvinyl chloride (PVC) coated material. The friction between the PVC coated material of the guide screw washer 456 and bracket plate 104 adds to a friction between the back side 109 of the bracket plate 104 and the front side 206 of the support column 101 , caused by the tightening of the guide screw 450 and the guide T-nut 454 disposed in the T-bar guide 407, to thereby ensure the bracket 102 does not slide and stays in place under the weight of an article resting on the protrusion 106 extending from the bracket plate 104.

[0035] Another way to support adjustment of a distance between the brackets 102 is by providing grooves or holes along inside sidewalls of the guide channel 400 and placing pins in those holes or groves that would stop the guide screw 450 coupled to bracket plate 104 and T- nut 454 from traveling downwards under the weight of the stored article and along the guide channel 400. According to another example, grooves or holes for support pins may be provided in a bottom wall of the channel 400. [0036] FIG. 5 is a diagram of a bracket mounted on a rack, according to another example of the present disclosure. Referring to FIG. 5, the channel 400 may be in form of a routed channel, or through channel, 502 formed by way of an opening through the front and back sides 206, 208, respectively, of the support column 101. The opening of the channel 502 may be a single open through channel, or route, along the vertical axis of the support column 101 , or a plurality of openings as coupling and position guides along the vertical axis of the support column 101.

[0037] Referring to FIG. 5, at least two guide couplers 510 couple the bracket 102 to a plate holder 514 and the support column 101. The guide couplers 510 may be screws and

corresponding nuts. The screws 510 go through the guide piece 512, which keeps the bracket 102 centered along the routed guide channel 502. By tightening wing nuts 516, the plate holder 514 is pressed against the back side 208 of the support column 101 , preventing the bracket assembly 102 from sliding and holding the bracket assembly 102 at a desired position along the channel 502.

[0038] FIG. 6 is a diagram of a support column assembled to a baseplate, according to an example of the present disclosure. A modular rack 100 and a method of assembling the modular rack 100 is described. To assemble the rack 100, the long column 101 is coupled to the short column 226 of the baseplate 103. The long column 101 is aligned and linked with the short column 226 through a vertical joint (v-joint) 600 embedded in and protruding from the short column 226, the v-joint 600 to be received by, or inserted in, a corresponding groove v-joint 602 in the long column 101. A plurality of v-joints 600 may be provided, for example, a pair, or a single v-joint 600 may be provided. A long column anchor 404 including an anchor post 405 is at the long column 101. The long column anchor 404 may be a single long column anchor. The long column anchor 404 is embedded in and protrudes from the long column 101 to be received by, or inserted into, a correspondingly shaped long column anchor groove 604, and the anchor post 405 includes a threaded portion to accept an anchor post coupler 406, for example, a screw.
