Description

[Technical field]

[0001] The present invention relates to a handrail support and a handrail device that can not only extend the terminal of a handrail even in places where the installation floor surface is restricted, but also can be used when installed along a staircase. [Background technology]

[0002] 2. Description of the Related Art In order to ensure the safety of elderly people, people requiring nursing care support, and the like when they walk on their own at home, in nursing facilities, hospitals, and the like, handrails are attached to the walls of corridors and staircases, or stationary handrail devices or handrail systems are installed in corridors, entrances, etc.

[0003] For example, in cases where a handrail is desired at the entrance to help people move over the step between the property and the public road, there is a demand for the end of the handrail to be extended as far as possible until it reaches the public road.

[0004] Incidentally, conventionally, one example of a handrail that is suitable for installation at the end of a handrail is disclosed in Patent Document 1.

[0005] This handrail comprises a main handrail member, a terminal handrail member connected to one end of the main handrail member via a handrail member connector, and a post supporting the handrail member connector, and a connecting auxiliary member is attached to the post, and this connecting auxiliary member has a post connection part connected to the post, an arm part protruding from the post connection part in the direction in which the terminal handrail member is inserted, and a terminal handrail member connection part formed at the tip of the arm, and the terminal handrail member is composed of a bent member formed by bending and / or curving a long member, and one end of the terminal handrail member is connected to the handrail member connector and the other end of the terminal handrail member is connected to the terminal handrail member connection part of the connecting auxiliary member.

[0006] This handrail has the advantage that it is less likely to get in the way of users because no support post is provided at the tip of the extended terminal handrail member. It also has the advantage of being aesthetically pleasing. In addition, it has the advantage of being strong because the terminal handrail member is fixed to the support post at one end and the other end.

[0007] In addition, when there is a staircase on one or both sides that is open on the approach to a front door and a handrail is installed along the edge of the open side to prevent people from falling from the open side, it may be preferable to install the handrail inside the edge of the stairs rather than directly above it, in order to prevent people from leaning too close to the handrail and accidentally slipping off the edge.

[0008] One example of a handrail that meets such a need is that disclosed in Patent Document 2.

[0009] This handrail is installed on inclined surfaces such as stairs or slopes, and comprises a number of posts erected along the edge of the inclined surface, a number of brackets attached to the posts so as to protrude toward the inside of the stairs or slope, and a handrail body erected on the upper ends of the brackets.

[0010] With this type of handrail, the handrail body is installed at a position inside the stairs, etc., so even if a user leans too close to the handrail body, it is possible to prevent an accident in which the user accidentally slips off the edge of the stairs, etc. [Prior art documents] [Patent documents]

[0011] [Patent Document 1] JP 2009-281067 A [Patent Document 2] Utility Model Registration No. 3241415 Summary of the Invention [Problem to be solved by the invention]

[0012] However, the conventional handrails described above required connecting auxiliary members consisting of many parts, such as a post and a terminal handrail member, a post connection portion connected to the post, a terminal handrail member connection portion connected to one end of the terminal handrail member, and an arm portion connecting these post connection portion and the terminal handrail member connection portion, which made the assembly work complicated, which was an inconvenience.

[0013] Furthermore, it was only intended to be installed at the end of a handrail and was not suitable for installation along the edge of a staircase to prevent falls from stairs, slopes, etc. that are open on one or both sides.

[0014] In this regard, the handrail of Patent Document 2 can prevent the above-mentioned fall accident, but cannot meet the demand for extending the end of the handrail.

[0015] In conclusion, no handrail has been proposed to date that can simultaneously extend the handrail terminal and prevent accidents such as falls from the edge of stairs, etc.

[0016] The present invention has been made to solve the above-mentioned problems, and aims to provide a handrail support and handrail device which is extremely easy to assemble and which not only allows the end of the handrail to be extended even in places where the installation floor surface is restricted, but also allows for installation along places with height differences such as steps, entrance porches, and ramps, as well as along steps and inclined surfaces. [Means for solving the problem]

[0017] In order to solve the above problems, the handrail support of the present invention is a handrail support that erects and supports a handrail bar on a floor surface, and is characterized in that it comprises a rising part that is attached to the floor surface or side wall surface, a bracket having a handrail receiving part to which the handrail bar is attached, a support part to which the bracket is attached, and a displacement part that is interposed between the rising part and the support part and displaces the support part a predetermined distance in the horizontal direction from the rising part.

[0018] In the handrail support, the axis of the rising portion and the axis of the support portion may each be aligned vertically, and the two axes may be parallel to each other.

[0019] In the above handrail support, when the rising portion is attached to the side wall surface, the offset portion extends beyond the upper edge of the side wall surface and reaches above the floor surface, and the support portion is positioned on the floor surface.

[0020] The handrail device of the present invention is a handrail device consisting of a plurality of posts and handrail bars installed between these posts, characterized in that some or all of the plurality of posts are any of the handrail posts described above. Effect of the Invention

[0021] According to the present invention, it is possible to provide a handrail support and handrail device which is extremely easy to assemble and which not only allows the end of the handrail to be extended even in places where the installation floor surface is restricted, but also allows for installation along places with height differences such as steps, entrance porches, and ramps, etc. [Brief description of the drawings]

[0023] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the same reference numerals are used to designate the same components in the following embodiments.

[0024] An embodiment of a handrail support and a handrail device according to the present invention will be described with reference to Figs. 1 to 8.

[0025] As shown in Figures 3 and 4, the handrail support 1 is a handrail support that installs and supports a handrail bar 2 on a floor surface B. As shown in Figures 1 to 4, the handrail support 1 is equipped with a rising portion 3, a bracket 4, a support portion 6, and a displacement portion 5. In Figure 3, the symbol C indicates a decorative cover.

[0026] The rising part 3 is a part that is attached to the floor surface B. In the embodiment shown in FIG. 1, the rising part 3 is fixed to the concrete floor surface by embedding a region of a predetermined length from the lower end when concrete is poured. In the example shown in FIG. 2, the rising part 3 is attached to the floor surface B via a base plate 71 that is fixed, for example, by an anchor bolt. Specifically, the rising part 3 is inserted into a receiving hole of the base plate 71 and fastened to the base plate 71 by a fixing member 81 such as a bolt and nut. Alternatively, as shown in FIG. 5, the rising part 3 is attached to the side wall surface S1 of the stairs S via a support side bracket 72. Specifically, the rising part 3 is gripped by the support side bracket 72 made of a half-split member, and the support side bracket 72 is fixed to the side wall surface S1 of the stairs S by the anchor bolt 82, thereby being attached to the stairs S.

[0027] The bracket 4 is a portion that receives the end of the handrail bar 2, and has a handrail receiving portion 41 to which the end is attached. As shown in Figures 1 and 2, the bracket 4 is attached by bolts, nuts, etc. 45 to a mounting portion 44 that protrudes from the upper end of the small diameter portion 62 of the support portion 6 so as to be able to tilt freely. Note that the bracket 4 is not limited to the above example, and for example, it may be connected to the support portion 6 by a universal joint.

[0028] The support part 6 is composed of a large diameter part 61 and a small diameter part 62. The lower end of the small diameter part 62 is removably inserted into the cylindrical large diameter part 61, and the protruding height from the upper end of the large diameter part 61 can be adjusted. This makes it possible to adjust the height position of the bracket 4. A conventionally known structure may be appropriately used as a structure for attaching the small diameter part 62 to the large diameter part 61 so that the small diameter part 62 can be removably inserted into and fixed at any position. If such height adjustment is not necessary, the support part 6 may be composed of only the large diameter part 61 without the small diameter part 62, and the bracket 4 may be directly attached to the upper end of the large diameter part 61.

[0029] The offset portion 5 is interposed between the rising portion 3 and the support portion 6, and as shown in Figs. 3 and 4, offsets the support portion 6 from the rising portion 3 by a predetermined dimension in the horizontal direction. Specifically, it includes a lower curved portion 51 connected to the rising portion 3, an upper curved portion 53 connected to the support portion 6 (in this example, the large diameter portion 61 of the support portion 6), and a straight portion 52 located between these upper and lower curved portions 51, 53. Normally, the rising portion 3 and the support portion 6 are each aligned in the vertical direction and are in a parallel relationship with each other. The offset portion 5 determines the horizontal distance (see Fig. 4) between the rising portion 3 and the support portion 6, which are in a parallel relationship. The distance is determined according to the installation environment of the handrail bar 2. In the example shown in Figure 4, as indicated by the arrow in the figure, it is desired to extend the end of the handrail bar 2 up to just above the boundary line L between the residential site P and the public road R, but since it is not legally permitted to install the handrail support 1 on the boundary line L, the handrail support 1 must be set back from the boundary line L into the site P to a location where the ground is stable, and this setback distance is roughly the horizontal distance between the rising part 3 and the support part 6. Specifically, a distance of approximately 100 mm to 200 mm is suitable from the standpoint of ease of construction, but is not limited to this.

[0030] As described above, the handrail support 1 has a configuration in which the rising portion 3, the offset portion 5, and the support portion 6 are integrally connected, so that it requires far fewer parts than the conventional handrail described above, making assembly extremely easy, reducing manufacturing and transportation costs, and enabling the end of the handrail to be extended even in places where the installation floor surface is limited.

[0031] FIG. 5 is a perspective view showing an example of a handrail device 9 according to the present invention installed on a staircase S. In this example, two handrail supports 1 as shown in FIG. 1 are used, and as described above, each handrail support 1 is attached to the side wall surface S1 of the staircase S via a support side bracket 72. Here, each handrail support 1 is attached so that the inclination direction of the offset portion 5 faces the inside of the staircase S, as shown in FIG. 6, so that the handrail bar 2 is installed at a position from the edge of the staircase S to the inside of the staircase S. That is, when the rising portion 3 of the handrail support 1 according to the present invention is attached to the side wall surface S1, the offset portion 5 reaches the floor surface beyond the upper edge of the side wall surface S1, and the support portion 6 is disposed on the floor surface. By attaching the handrail device 9 equipped with the handrail support 1 to the staircase S in this manner, the handrail bar 2 is recessed inward from the edge of the staircase S by a distance D. This means that even if a user leans their body against the handrail bar 2, their foot will remain in a position inside the edge of the staircase S, preventing accidents such as slipping off the edge of the staircase S and falling.

[0032] Fig. 7 is a perspective view showing an example in which the handrail support 1 shown in Fig. 1 is used on a staircase S. In this example, even if it is impossible to install a support post at the location connected to the lowest step S2 of the staircase S due to a gutter cover or grating, or if it is necessary to leave an edge clearance dimension to the core or anchor pilot hole near the step, it is possible to extend the end of the handrail bar 2 to almost directly above the step (extending by a distance D) as shown in Fig. 8.

[0033] The handrail device 9 according to the present invention naturally includes the configuration shown in Fig. 3 in addition to the configuration shown in Fig. 5 as described above. That is, the handrail support 1 described above is used as a support for receiving the end of the handrail bar 2, making it possible to extend the position of the end of the handrail bar 2, and the other parts of the handrail bar 2 are supported by multiple vertical supports 10. Like the handrail support 1, each vertical support 10 is composed of a large diameter part 11 and a small diameter part 12, and a bracket 13 of a shape corresponding to the mounting position is attached to the upper end of the small diameter part 12 so that it can tilt freely. This makes it possible to adjust the height position of the handrail bar 2 by adjusting the protruding height of the small diameter part 12 from the large diameter part 11. However, like the handrail support 1, if such height adjustment is not necessary, the small diameter part 12 may be omitted and only the large diameter part 11 may be configured, and the bracket 13 may be directly attached to the upper end of the large diameter part 11. The handrail device 9 of the present invention is not limited to a combination of a handrail post 1 that supports the end of a handrail bar 2 and a vertical post 10 that supports the middle of the handrail bar 2 as shown in FIG. 3, or a combination of multiple handrail posts 1 as shown in FIG. 5. Although not shown, it may be, for example, a combination of a handrail post 1 and a bracket that is directly attached to a wall surface.

[0034] The present invention can be embodied in various other forms without departing from its spirit or main features. Therefore, the above-described embodiments are merely illustrative in all respects and should not be interpreted as being limited. The scope of the present invention is indicated by the claims and is not restricted by the descriptions in the specification and drawings. Furthermore, all modifications and changes within the scope of the claims are within the scope of the present invention. [Explanation of symbols]
