Description

The present invention relates to a floor-mounted handrail.

Elderly people and people with leg disabilities may have difficulty performing normal daily activities such as standing up and sitting down, lying down in bed and getting up, and going up and down steps in various places such as at home, public facilities, hospitals, and nursing homes. In such cases, having a handrail installed is convenient for both the person and the caregiver, but it is often difficult to smoothly install a fixed handrail in a place where one was not originally installed due to factors such as cost and construction. For this reason, floor-mounted handrails that are adapted to the required location and with due consideration given to safety are used (see Patent Document 1, for example).

In order to prevent such floor-mounted handrails from taking up too much space when transporting them to and from the site, and to allow for changes to the placement location and changes to the style and position of the handrail to a certain extent, it is preferable for them to be prefabricated so that assemblers can easily assemble and disassemble them on-site. In other words, there is a demand for the positions of the handrail and base plate to be easily changed according to the situation on-site, such as when you want to attach the handrail closer to the wall without changing the position of the base plate, or when you want to change the position of the base plate without changing the position of the handrail.

Utility Model Registration No. 3185591

However, some existing prefabricated floor-mounted handrails use tools such as a screwdriver to fasten the posts that support the handrail to the back of the base plate with bolts. This means that tools must always be prepared along with the floor-mounted handrail for assembly and disassembly, and because assembly and disassembly are carried out on the back of the base plate, there is the issue that unfamiliar use of tools can hinder smooth movement and changes.

Patent Document 1 also discloses a technique in which a fixing screw (fastening plug), which is not a bolt, protrudes from a post mounting hole (through hole) from the back side of the base plate (base) and the post (support tube) that supports the handrail (frame) is screwed into the fixing screw, making it possible to attach the base plate and post substantially without tools. However, in Patent Document 1, the fixing screw is only inserted into the post mounting hole from the back side, so the assembler who assembles the handrail must fix the fixing screw from the back side of the base plate with their own hands, etc., which poses the problem that it is difficult to assemble or disassemble from the front side of the base plate, i.e., in a position that is convenient for the assembler.

In view of the above problems with the conventional technology, the present invention aims to provide a floor-mounted handrail that does not require tools to assemble or disassemble the back side of the floor-mounted handrail, and that makes it easy for the assembler to assemble or disassemble in a position that is convenient for the assembler.

In order to achieve the above object, the present invention is realized by the following configuration.
(1) A first aspect of the present invention is a floor-mounted handrail comprising: a base plate having a post mounting hole; a fixing screw that is inserted into the post mounting hole from the back side of the base plate in a non-rotating and non-falling manner, and has a flange portion covering the post mounting hole on the back side of the base plate and a threaded portion protruding from the post mounting hole on the front side of the base plate; a post whose lower portion is screwed into the threaded portion of the fixing screw from the front side of the base plate; and a handrail attached to the upper part of the post.

(2) In the configuration of (1) above, the post mounting hole has a rotation stopper cut out radially outward, and the fixing screw has a protrusion on the flange portion that fits into the rotation stopper, thereby making the fixing screw non-rotating relative to the base plate.

(3) In the configuration of (1) or (2) above, a fall-prevention plate is further provided that is fitted into the thread groove of the threaded portion of the fixing screw from the front side of the base plate, thereby preventing the fixing screw from falling off from the base plate.

The present invention provides a floor-mounted handrail that does not require tools to assemble or disassemble the back side of the handrail, and allows the assembler to easily assemble or disassemble the handrail in a position that is convenient for the assembler.

(Embodiment)
A floor-mounted handrail 100 according to an embodiment of the present invention will be described with reference to the drawings.

(Overall overview of floor-mounted handrails)
An overall outline of an example of a floor-mounted handrail 100 will be described with reference to Fig. 1. The floor-mounted handrail 100 includes, as basic components, a base plate 1 placed on the floor, a post 2 attached to the base plate 1, and a handrail 3 attached to the post 2.

In the following, the floor-mounted handrail 100 according to this embodiment will be described using the configuration shown in FIG. 1, but the attachment means of the support 2 to the base plate 1, which is the gist of this embodiment described later, can also be applied to floor-mounted handrails 100 formed in configurations other than that shown in FIG. 1. In other words, the shapes of the base plate 1, support 2, and handrail 3, and the number and positions of the legs 31 of the support 2 and handrail 3 are not limited to the configuration shown in FIG. 1. The floor-mounted handrail 100 can be in various configurations according to specific applications, so examples of configurations other than that shown in FIG. 1 will be described in a separate section later.

The floor-mounted handrail 100 shown in Figure 1 is an embodiment in which a handrail 3 extending along the longitudinal direction is placed on the short end of a base plate 1 that is a rounded rectangle in plan view (this embodiment can be called, for example, a "long type"). This embodiment is suitable for supporting the user's action of "walking" a distance corresponding to the length of the handrail 3.

In consideration of stability, safety, and ease of assembly (described later), the base plate 1 has an inner flat surface 11 that is raised higher than the peripheral edge 12, leaving a space between the back of the base plate 1 and the floor. The flat surface 11 is provided with a post mounting hole 13 for mounting the post 2. The peripheral edge 12 is smoothly inclined, and a soft guard 12a may be provided on the outer edge to prevent injury due to friction with the floor or tripping by the user.

In Fig. 1, the post 2 is shown attached to the post mounting hole 13 located at the end of the short side of the base plate 1 so that the handrail 3 can be aligned along the wall, but depending on the situation of the installation location, the handrail 3 may also be attached to the post mounting hole 13 located in the center of the short side of the base plate 1. In the figure, for safety, a cap 6 is fitted into the post mounting hole 13 located in the center of the short side so that the post mounting hole 13 does not remain open when not in use.

The handrail 3 has an upper section 32 on which the user places their hands, and a lower section 33 for added strength. The height of the handrail 3 is adjustable as described below. The number and positions of the lower sections 33, like the legs 31, are not limited to those shown in FIG. 1.

(Attaching the support to the base plate)
2 to 6, the attachment of the support 2 to the base plate 1 will now be described in detail.

Figure 2 is an enlarged view showing the state in which the support 2 is attached to the base plate 1, and Figure 3 is an exploded view explaining the relative positions of the base plate 1, support mounting hole 13, support 2 (support body 21), fixing screw 4, and anti-falling plate 5. Figures 4 to 6 are diagrams explaining the installation procedure in which the fixing screw 4 is inserted into the support mounting hole 13 in a non-rotating and non-falling state.

As shown in Figures 2 and 3, the support 2 has a support body 21 and a cover 22 (described in detail later), and the support body 21 is screwed at its lower part into a fixing screw 4 that is inserted in a non-rotating and non-falling state into the support mounting hole 13 from the back side of the base plate 1.

To summarize again, the floor-mounted handrail 100 comprises a base plate 1 with a post mounting hole 13, a fixing screw 4 that is inserted from the back side of the base plate 1 into the post mounting hole 13 in a non-rotating and non-falling state and has a flange portion 41 that covers the post mounting hole 13 on the back side of the base plate 1 and a threaded portion 42 that protrudes from the post mounting hole 13 on the front side of the base plate 1, a post 2 whose lower portion is screwed into the threaded portion 42 of the fixing screw 4 from the front side of the base plate 1, and a handrail 3 that is attached to the top of the post 2.

The specific configuration in which the fixing screw 4 is inserted into the post mounting hole 13 in a non-rotating and non-falling state is as follows:

As a means for non-rotating the fixing screw 4, for example, as shown in Figures 3, 4 and 5(a), a rotation stopper 13a is provided in the post mounting hole 13, cut out radially outward, and a protrusion 41a is provided on the threaded portion 42 side of the flange portion 41 of the fixing screw 4, and the protrusion 41a is fitted into the rotation stopper 13a, so that the fixing screw 4 is non-rotating relative to the post mounting hole 13 and thus the base plate 1.

As a means for preventing the fixing screw 4 from falling off, for example, as shown in Figures 3, 4, and 5(b), a fall prevention plate 5 is further provided to prevent the fixing screw 4 from falling off, and the fall prevention plate 5 is fitted into the root-most screw groove 42a of the threaded portion 42 of the fixing screw 4 protruding from the front side of the base plate 1, so that the fixing screw 4 will not fall off from the post mounting hole 13 and therefore from the base plate 1.

The fall prevention plate 5 is formed as a doughnut-shaped disk, and multiple notches 51b are provided on the inner edge 51a of the disk portion 51. The outer edge 51c of the disk portion 51 is erected. Note that while FIG. 4 shows an example in which four notches 51b are provided on all four sides, they may be provided in any number and positions depending on the material and strength of the disk portion 51.

To summarize and supplement the procedure for installing the fixing screws 4 and the support posts 2, first prepare the support posts 2 (support post main body 21), the fixing screws 4, and the fall prevention plate 5 on the front side of the base plate 1 as shown in Figure 4. As described above, the support post mounting holes 13 are provided with rotation stoppers 13a cut out radially outward, but the rotation stoppers 13a penetrate the base plate 1 in the same way as the support post mounting holes 13. For unused support post mounting holes 13, caps 6 are attached to close the openings after assembly.

Next, as shown in FIG. 5(a), when the protrusion 41a of the fixing screw 4 is aligned with the rotation stopper 13a and the fixing screw 4 is inserted into the post mounting hole 13 from the back side of the base plate 1, the flange 41 of the fixing screw 4 comes into contact with the back side of the base plate 1. Here, the shapes of the rotation stopper 13a and the protrusion 41a are not particularly limited, and may be semicircular or the like in addition to the rectangular shape shown. In addition, while one rotation stopper 13a and one protrusion 41a are provided in the illustrated embodiment, they may also be provided in opposing positions to form a pair of rotation stoppers 13a and a pair of protrusions 41a.

Then, in the state shown in FIG. 5(a), the fall prevention plate 5 is fitted to the threaded portion 42 of the fixing screw 4 as shown in FIG. 5(b). To do so, the disk portion 51 is inserted through the threaded portion 42 and the inner edge 51a of the disk portion 51 is pushed in until it fits into the thread groove 42a at the very base of the threaded portion 42. As described above, the inner edge 51a of the disk portion 51 has a notch 51b, which is formed so that the disk portion 51 can flexibly deform as it passes through the threads of the threaded portion 42.

After the fixing screw 4 is inserted into the base plate 1 in this manner in a non-rotating and non-falling state, the lower part of the support 2 (support body 21) is screwed into the threaded part 42 of the fixing screw 4 to fasten it, as shown in Fig. 6(a) and Fig. 6(b). As shown in the figure, the threaded part 42 of the fixing screw 4 is male threaded 42b, and the lower part of the inner circumference of the support 2 (support body 21) is female threaded 21b. The lower end of the support 2 (support body 21) is sized to abut against the erected outer edge 51c of the disk part 51 of the fall prevention plate 5, so as to prevent the support 2 (support body 21) from wobbling. The shape of the support 2 (support body 21) is not particularly limited, but here, a form in which the center part is tapered like a drum is shown so that the assembler can easily rotate it by hand.

The manner in which the fixing screw 4 is inserted into the post mounting hole 13 of the base plate 1 can be modified as follows, for example, and will be described with reference to Figures 7 and 8. In one modification, the rotation stopper 13a cut out on the radially outer side of the post mounting hole 13 shown in Figure 4 is made to protrude radially inward of the post mounting hole 13 to form the rotation stopper 13b, as shown in Figure 7. In this case, instead of the protrusion 41a described above, the fixing screw 4 is formed with a vertical groove (not shown) through the flange portion 41 and the threaded portion 42 so that the rotation stopper 13b can pass through. The anti-fall-out plate 5 is attached as described above.

In another modified example, as shown in FIG. 8, a claw 41b is provided integrally with the fixing screw 4, and the claw 41b is hooked on the front side of the base plate 1 after the fixing screw 4 is inserted into the post mounting hole 13, with the rotation stopper 13a cut out radially outward from the post mounting hole 13 as shown in FIG. 4. The rotation stopper 13a may be the rotation stopper 13b protruding radially inward from the post mounting hole 13 as shown in FIG. 7. In this case, the fixing screw 4 can prevent itself from falling off the base plate 1, so the fall prevention plate 5 can be omitted. However, as shown in FIG. 6(a) and FIG. 6(b), if the lower end of the post 2 (post main body 21) is abutted against the upright outer edge 51c of the disk part 51 of the fall prevention plate 5 to prevent the post 2 (post main body 21) from wobbling, the fall prevention plate 5 may be attached subsequently, and the arrangement of the fall prevention plate 5 may be appropriately selected depending on the usage mode of the floor-mounted handrail 100.

In the above explanation using Figs. 4 to 8, it has been assumed that the handrail 3 is attached to the post 2 after the post 2 (post main body 21) is attached to the base plate 1, but as shown in Fig. 9, it is also possible to fasten the post 2 by screwing it into the fixing screw 4 while the handrail 3 is attached to the post 2. This is because the post 2 and the handrail 3 are not fastened by screwing or the like, so the post 2 can be rotated independently of the handrail 3, that is, fastened by screwing it into the fixing screw 4. Since the post 2 can be attached to and removed from the base plate 1 without removing the handrail 3 from the post 2, the labor hours for transportation can be significantly reduced compared to the existing fastening method in which the post 2 and the handrail 3 are fastened by screwing or the like.

Now, we will explain how to attach the post 2 to the handrail 3. As shown in Figure 10, the post 2 comprises a post body 21, a cover 22, and a height adjustment member 23. The post body 21 and cover 22 are cylindrical members, and are fastened together by screwing together a male thread 21a protruding from the top of the post body 21 and a female thread 22a provided on the lower inner circumference of the cover 22. The height adjustment member 23 is a resilient C-shaped band with a rib 23a on its inner circumference.

Meanwhile, the leg 31 of the handrail 3 is provided with a number of height adjustment grooves 31a for adjusting the height of the handrail 3, and the height of the handrail 3 can be adjusted by fastening the rib 23a of the height adjustment member 23 to the desired height adjustment groove 31a. To attach the post 2 and the handrail 3, the height adjustment member 23 (rib 23a) is fastened to the leg 31 (height adjustment groove 31a) of the handrail 3, and then the cover part 22 is aligned so that its upper inner periphery abuts the upper end of the height adjustment member 23, and the female thread 22a of the cover part 22 is screwed into the male thread 21a of the post main body part 21. A protective cap 31b is provided at the tip of the leg 31 of the handrail 3.

By configuring it in this way, not only does the assembler not need to use tools to attach the base plate 1 and the post 2, but the post 2 and the handrail 3 can also be screwed together and released without the use of tools, making it even easier to assemble and disassemble the floor-mounted handrail 100.In addition, because the post 2 and the handrail 3 are not fastened together by screwing or the like, the post 2 can be screwed together and released from the fixing screw 4 even when in the state shown in Figure 9, i.e., when the post 2 and the handrail 3 are still attached.

Above, we have explained how to attach the base plate 1 to the support post 2, and how to attach the support post 2 to the handrail 3. We will summarize the cross-sections of the base plate 1, support post 2, and handrail 3 when they are attached using Figures 11 to 16.

Figure 11 is a front view showing the base plate 1, the post 2, and the handrail 3 attached to one another, Figure 12 is an example of a cross-section of Figure 11, and Figure 13 is an enlarged view of a portion of Figure 12. Figure 14 is another example of the cross-section of Figure 11, and Figure 15 is an enlarged view of a portion of Figure 14. Figure 16 is a cross-section showing the state in which the cap 6 is fitted into the post mounting hole 13.

Figure 12 shows an example of a cross section of the exterior appearance of the base plate 1, support post 2, and handrail 3 after installation as shown in Figure 11 is completed. First, the installation method of the support post 2 and the handrail 3 will be explained with reference to Figure 12. The installation method of the base plate 1 and support post 2 will be explained separately with reference to the enlarged view of Figure 13.

Figure 12 shows a case where the rib 23a of the height adjustment member 23 is fastened to the highest height adjustment groove 31a among the multiple height adjustment grooves 31a provided in the leg 31 of the handrail 3. In this case, the leg 31 is closest to the fixing screw 4, that is, the handrail 3 is provided at the lowest position. Note that while Figure 12 shows an example where three height adjustment grooves 31a are provided, they may be provided in any number and at any spacing depending on the purpose and installation location of the floor-mounted handrail 100.

As described above, after fastening the rib 23a of the height adjustment member 23 to the height adjustment groove 31a of the leg 31 of the handrail 3, the cover part 22 is aligned so that its upper inner periphery abuts the upper end of the height adjustment member 23, and the female thread 22a of the cover part 22 and the male thread 21a of the pillar body part 21 are screwed together. The manner of attachment of the pillar 2 and the handrail 3 is the same regardless of the position of the height adjustment groove 31a to which the rib 23a of the height adjustment member 23 is fastened.

Figure 13 shows an enlarged view of the mounting of the base plate 1 and the support 2 in Figure 12. In the threaded portion 42 of the fixing screw 4 inserted into the support mounting hole 13 from the back side of the base plate 1 and protruding to the front side, the inner edge 51a of the anti-fall-out plate 5 fits into the screw groove 42a at the very base of the threaded portion 42. This prevents the fixing screw 4 from falling out of the support mounting hole 13 and the base plate 1. In addition, the protrusion 41a provided on the flange portion 41 of the fixing screw 4 is fitted into the rotation stopper portion 13a, which prevents the fixing screw 4 from rotating relative to the support mounting hole 13 and the base plate 1. The male thread 42b of the fixing screw 4 and the female thread 21b at the lower inner circumference of the support 2 (support body portion 21) are screwed together. The lower end of the support 2 (support body 21) abuts against the upright outer edge 51c of the disk portion 51 of the fall prevention plate 5. Note that FIG. 13 illustrates the case where the protective cap 31b abuts against the top of the threaded portion 42 of the fixing screw 4, but depending on the height of the handrail 3, the protective cap 31b and the top of the threaded portion 42 of the fixing screw 4 may be spaced apart.

Here, the fixing screw 4 may be of the type shown in Figs. 14 and 15 instead of the type shown in Figs. 12 and 13. That is, the former shows an example in which the flange portion 41 and the threaded portion 12 are integrally molded using, for example, resin, while the latter shows an example in which the flange portion 41 is made of steel and the threaded portion is made of resin, and the two are fastened with a bolt 43 and a nut 44 to form a two-piece combination. Depending on the type of handrail 3, a large load is applied to the attachment point between the support 2 and the base plate 1, so in such cases, the latter two-piece combination fixing screw 4 is useful for increasing the strength of the attachment point. In particular, in the case of the floor-mounted handrail 100 type shown in Fig. 1 (called the long type), the longer the span of the leg portion 31 of the handrail 3, the stronger the attachment point needs to be, so the two-piece combination fixing screw 4 can be preferably used. On the other hand, the former integrally molded fixing screw 4 can be preferably used in long types where the span of the leg 31 of the handrail 3 is relatively short, or in other floor-mounted handrail 100 configurations (called side types, corner types, etc.) described below where the span of the leg 31 of the handrail 3 is originally short.

The aspects other than the fixing screw 4 in Figures 14 and 15 are the same as those in Figures 12 and 13, so their explanation will be omitted.

Figure 16 shows a cross section of the cap 6 fitted into the post mounting hole 13 and the rotation stopper 13a. The post mounting hole 13 and the rotation stopper 13a of the base plate 1 (flat surface portion 11) are covered with the cap 6 because leaving them open while not in use poses safety issues, such as feet, socks, clothing, etc. getting caught in them.

(A collection of floor-mounted handrails)
As described above, the floor-mounted handrail 100 according to this embodiment can easily screw in/unscrew the base plate 1 and the support pole 2 without using tools. Therefore, compared to the existing floor-mounted handrail 100A in which the support pole 2 is fixed with a bolt and is carried in/out while the support pole 2 is fixed, the floor-mounted handrail 100 can detach the support pole 2 from the base plate 1 in a short time, which makes it possible to significantly reduce the space occupied by multiple floor-mounted handrails 100 assembled together when carrying in/out.

In this regard, FIG. 17 is a diagram showing a comparison of how multiple floor-mounted handrails 100A, 100 are assembled horizontally when being carried in/out, with FIG. 17(a) showing a case where an existing floor-mounted handrail 100A is laid flat with the support pole 2 fixed, and FIG. 17(b) showing a case where an existing floor-mounted handrail 100A is laid diagonally with the support pole 2 fixed. Both show a relatively large occupied space (a cube drawn by virtual lines). In contrast, FIG. 17(c) shows a case where only the base plate 1 is stacked with the support pole 2 and fixing screw 4 removed for the floor-mounted handrail 100 according to this embodiment, and the occupied space is significantly reduced.

Figure 18 is a comparative diagram showing how multiple floor-mounted handrails 100A, 100 are assembled vertically when being brought in/out. Figure 18(a) shows the existing floor-mounted handrail 100A placed vertically with the support pole 2 fixed, which also requires a relatively large space (cube depicted by virtual lines), whereas Figure 18(b) shows the floor-mounted handrail 100 according to this embodiment placed vertically with the support pole 2 removed, which occupies a significantly reduced space. Figure 18(b) shows the state in which the fixing screws 4 are attached to the base plate 1, and the fixing screws 4 are alternated for adjacent base plates 1.

(Another aspect of the floor-mounted handrail)
Finally, other aspects of the floor-mounted handrail 100 according to this embodiment will be described. For example, the floor-mounted handrail 100 may be configured such that the handrail 3 extending along the short side of the base plate 1, which is a rounded rectangular shape in plan view, is disposed at the end of the long side (this aspect may be called, for example, a "side type"). This aspect is suitable for supporting the user's actions such as "getting out of bed or futon,""standingup/sitting," and "maintaining posture while standing."

Floor-mounted handrail 100 may also be configured with one handrail 3 extending continuously in the short direction of base plate 1 and two handrails extending continuously in the long direction, i.e., the handrails 3 are arranged so as to form a U-shape in plan view (this configuration may be called, for example, a "corner type"). This configuration is suitable for supporting the user's movement of "turning their body around" after getting out of bed or futon, for example to transfer to a portable toilet.

The floor-mounted handrail 100 may also be configured so that the handrail 3 is positioned in a forward-leaning posture to make it easier to "stand up" or "sit down" in a small space (this configuration may be called, for example, the "small type"). This is suitable for supporting the user's actions of "standing up" or "sitting down" on the toilet, for example. When placed on a toilet, the base plate 1 is cut out to match the shape of the toilet bowl.

Floor-mounted handrail 100 may also be arranged so that one handrail 3 on one side (or two on both sides) extends diagonally up and down along the short side of base plate 1 to facilitate the action of "going up/down" in a space with a step such as an entrance (this aspect may be called, for example, the "step-up type"). In this case, base plate 1 is placed on the lower level so that its longitudinal direction is parallel to the step surface, and two legs 31 and supports 2 of handrail 3 are provided on base plate 1 along the short side, and one is placed directly on the upper level such as the floor of the entrance. This aspect is suitable for supporting the actions of users such as "standing/sitting" at the entrance and "going up/down" on steps. The handles on both ends of the upper and lower levels of handrail 3 may be horizontal, which provides firm support for the body when taking off shoes or going up a step, and prevents clothes from getting caught.

(Effects of the embodiment)
In this embodiment, as described above, the floor-mounted handrail 100 is configured to include a base plate 1 having a post mounting hole 13, a fixing screw 4 that is inserted from the back side of the base plate 1 into the post mounting hole 13 in a non-rotating and non-falling state, a flange portion 41 that covers the post mounting hole 13 on the back side of the base plate 1 and a screw portion 42 that protrudes from the post mounting hole 13 on the front side of the base plate 1, a post 2 whose lower portion is screwed into the screw portion 42 of the fixing screw 4 from the front side of the base plate 1, and a handrail 3 that is attached to the top of the post 2. This makes it possible to provide a floor-mounted handrail 100 that does not require tools for assembly or disassembly on the back side of the floor-mounted handrail and that makes it easy to assemble and disassemble in a position that is convenient for the assembler, that is, working on the front side of the base plate 1. This makes it possible to easily change the positions of the handrail 3 and the base plate 1 according to the situation on site, such as when you want to attach the handrail 3 closer to the wall without changing the position of the base plate 1, or when you want to change the position of the base plate 1 without changing the position of the handrail 3.
