Description

  The present invention relates to a handrail attachment structure. More specifically, the present invention relates to a handrail attachment structure used when a handrail is attached to a wall surface in a corridor, a staircase, or the like.

Conventionally, when a handrail is attached to a wall surface such as a hallway or a staircase, a handrail bracket is generally used and a handrail bar is fixed to the bracket. In this case, it is necessary to construct a reinforcing means such as a trunk edge on the back surface of the wall surface.For example, when adding a handrail to the wall surface for barrier-free construction, the construction of the reinforcing means and the installation position Since confirmation and the like are required, there is a problem in that it takes time and work is complicated. Therefore, a handrail attachment structure that can be directly applied to the wall surface without applying reinforcing means has been proposed.
Japanese Patent Laid-Open No. 2001-81929 (page 1-3, FIG. 1)

  However, in the above technique, the wall surface is cut along the attachment portion of the handrail to form a groove, a rail material is fitted into the groove, and a bracket is attached to the rail material to fix the handrail rod. It must be quite complicated. An object of the present invention is to solve such problems and to provide a handrail attachment structure capable of easily attaching a handrail to a wall surface with good workability.

In order to solve the above problems, the following technical means are taken in the present invention. That is, according to the present invention, the mounting base, the pedestal portion, and the handrail portion are provided, the mounting base supports the rail portion having the substantially U-shaped side section and the rail portion, and is fixed to the wall surface. The pedestal portion has a long fitting portion that is fitted and fixed to the rail portion, and a plurality of handrail support portions are arranged at regular intervals in the longitudinal direction of the fitting portion. A handrail mounting structure is provided which is provided in a protruding manner and attaches the handrail by attaching the handrail portion to the plurality of handrail support portions . A well-known method, such as adhesion and screwing, can be employed for fitting and fixing the pedestal to the rail. Moreover, as a base part, various molded articles, such as a synthetic resin, a wood type material, and a metal, are used, without specifically limiting, such as an integral molded article and a hollow molded article.

  The mounting base can be made of a material that can be integrally molded, for example, synthetic resin, steel, stainless steel, aluminum, etc., but is particularly preferably used because aluminum is lightweight and can be advantageously obtained in terms of cost. It is done. The fixing of the mounting base to the wall surface is not particularly limited, such as adhesion and screw fixing. However, a screw hole for fixing the screw to the fixing portion of the mounting base is provided, and a screw is provided in the screw hole. It is preferable that the screw is inserted and screwed and fixed to the wall surface.

  Moreover, it is preferable that the handrail portion includes a plurality of handrail portions supported by the handrail support portion while projecting handrail support portions on the pedestal portion at regular intervals. Or a long handrail part can also be attached to the said base part via a some bracket.

The invention according to claim 1 is as described above, wherein the mounting base includes a rail portion having a substantially U-shaped side section, and a fixing portion that supports the rail portion and is fixed to a wall surface. Since the handrail part is mounted via a plurality of handrail support parts protruding from a long pedestal part that is fitted and fixed to the part, the load is distributed without being biased locally on the wall surface. The wall can be prevented from being damaged or damaged.

Together with the mounting base is integrally molded from aluminum, the fixed portion of the mounting base when the screw holes for fixing to the wall is provided, which screw fixation at the wall fixing screw inserted through the screw hole Thus, the mounting base can be firmly fixed to the wall surface.

Further, the handrail portion having a short handrail rods between the upper Symbol a certain interval more handrail support portion which projects, when have multiple bridged safely corridor holding the short handrail rods You can walk and go up and down stairs. Furthermore, since it is also possible to adopt a form in which a long handrail part is attached to the pedestal part via a plurality of brackets, it is possible to safely walk and walk up and down stairs by grasping this long handrail part. it can.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an exploded perspective view showing a first embodiment of a handrail mounting structure according to the present invention. In FIG. 1, the handrail mounting structure according to the first embodiment includes a mounting base 1, a pedestal portion 2, and a handrail portion 3. The U-shaped rail portion 11 and the fixing portion 12 that supports the rail portion 11 and is fixed to the wall surface are provided. The fixing portion 12 is provided with a screw hole 121 through which a wall fixing screw 71 described later is inserted. ing.

  The pedestal portion 2 includes a fitting portion 21, a handrail support portion 22 and a cover portion 23 that are fitted and fixed to the rail portion 11, and the handrail portion 3 includes a short handrail rod 31 and the handrail support. And a supported portion 32 supported by the portion 22. The supported portion 32 is fitted into a support hole 221 provided in the handrail support portion 22 and is covered with the cover portion 23.

  2 (a) is a plan view showing a state in which the above-described handrail attachment structure is attached to the wall surface W, and FIG. 2 (b) is a cross-sectional view taken along line AA in FIG. 2 (a). is there. 2A and 2B, the handrail portion 3 has its supported portion 32 fitted into the support hole 221 provided in the handrail support portion 22 as described above. The cover portion 23 is made up and is firmly fixed between the handrail support portions 22 provided at regular intervals. Therefore, a hand can be put in the grip space S formed between the fitting part 21 and the short handrail rod 31 and the short handrail rod 31 can be gripped, and the corridor can be safely walked and the stairs can be moved up and down.

  FIG. 3 (a) is a plan view showing a state in which the handrail attachment structure according to the second embodiment of the present invention is attached to the wall surface W, and FIG. 3 (b) is a view taken along line B- in FIG. 3 (a). It is sectional drawing which follows a B line. As can be seen from FIGS. 3 (a) and 3 (b), in the second embodiment, as in the first embodiment, the rail portion 11 and the rail portion 11 having a substantially U-shaped side section are supported. The mounting base 1 including a fixing portion 12 fixed to the wall surface is used, and the fixing portion 12 is provided with a screw hole 121 through which the wall fixing screw 71 is inserted. The pedestal portion 4 is fitted and fixed to the rail portion 11, and the bracket 5 is fixed to the pedestal portion 4 by a bracket fixing screw 72, and the long handrail portion 6 is attached to the bracket 5. Thus, the long handrail portion 6 can be firmly attached to the wall surface W via the pedestal portion 4, and the long handrail portion 6 can be grasped and the corridor can be safely walked and the stairs can be raised and lowered. Can do.

It is a disassembled perspective view which shows 1st embodiment of the attachment structure of the handrail concerning this invention. It is a top view which shows the state which attached the attachment structure of the said handrail to the wall surface. It is sectional drawing which follows the AA line in Fig.2 (a). It is a top view which shows the state which attached to the wall surface the attachment structure of the handrail concerning 2nd embodiment of this invention. It is sectional drawing which follows the BB line in Fig.3 (a).
