[0011] (Embodiment) An example of an embodiment of the present invention will be described with reference to the drawings. As an example, a handrail 30 shown in Fig. 1 and Fig. 2 comprises a base member 10 and a handrail member 20 attached to the base member 10. The base member 10 and the handrail member 20 in this embodiment are made by extrusion molding of aluminum. End covers 40 are attached to both ends of the base member 10 and the handrail member 20.

[0012] The base member 10 is a member for fixing the handrail member 20, and is fixed to various mounting surfaces such as a wall, a door, etc. The base member 10 in this embodiment is a long member having a U-shaped cross section, and includes a fixing portion 11 fixed to the mounting surface, and an upper protruding portion (base side first contact portion) 12 and a lower protruding portion (base side second contact portion) 13 that protrude from the surface of the fixing portion 11 opposite to the surface facing the mounting surface.

[0013] 2, 3(a) and 4(a), the upper protrusion 12 is a long plate having a length similar to that of the fixed portion 11, and has on its upper surface a locking receiving portion 12a that is locked by a locking portion 23b (described later) and a positioning engaging portion 12b that is engaged by a positioning portion 23c (described later). The locking receiving portion 12a is provided at a position closer to the fixed portion 11 than the positioning engaging portion 12b.

[0014] The locking receiving portion 12a in this embodiment is provided with a groove portion 12c elongated in the longitudinal direction and a retaining portion 12d provided on the upper periphery of the groove portion 12c, and the locking portion 23b (Fig. 3(b)) set in the groove portion 12c abuts against the retaining portion 12d, so that the handrail member 20 is held on the base member 10. The groove portion 12c has a clearance 12e (Figs. 6(a)(b)) sufficient to allow the set locking portion 23b to move inside the groove portion 12c.

[0015] The positioning engagement portion 12b is a portion that engages with a positioning portion 23c (FIG. 3(b)) described later. In this embodiment, the positioning engagement portion 12b is configured as a groove that is elongated in the longitudinal direction and has a hemispherical cross-sectional shape. In this embodiment, the positioning engagement portion 12b is provided at a position where the positioning portion 23c fits in when the locking portion 23b locks with the lock receiving portion 12a. In other words, the distance between the lock receiving portion 12a and the positioning engagement portion 12b is set to be equal to the distance between the locking portion 23b and the positioning portion 23c of the handrail member 20.

[0016] The lower protruding portion 13 is a long plate having a length similar to that of the fixed portion 11, and has an upwardly inclined surface that is inclined obliquely upward toward the tip end. (Base side inclined surface) The upward inclined surface 13a is a downward inclined surface of the handrail member 20 described later. (Sloped surface on the handrail side) 24b (Figures 3(b) and 4(b)) engages with and supports the upward force acting on the downward inclined surface 24b, and is a surface for fixing the stopper 41 used to fix the base member 10 and the handrail member 20.

[0017] The handrail member 20 is a long member that is attached to a base member 10 fixed to a mounting surface. As an example, the handrail member 20 shown in Fig. 2, Fig. 3(b) and Fig. 4(b) has a handle portion 21 that is approximately the same length as the base member 10. The handle portion 21 in this embodiment is a hollow member that is elliptical in cross section, but the shape of the handle portion 21 may be other than this, and may be an appropriate shape such as a perfect circle or a polygon. Furthermore, the handle portion 21 is not limited to a hollow structure and may also be a solid structure.

[0018] The lower side of the handle portion 21 is provided with a front portion 22 that faces forward when attached to the base member 10, an upper surface portion (first handrail side abutment portion) 23 that protrudes from the upper side of the front portion 22 toward the base member 10, a bottom surface portion 24 that protrudes from the lower side of the front portion 22 toward the base member 10, and a back surface portion 25 that is erected between the upper surface portion 23 and the bottom surface portion 24 in a direction facing the front portion 22.

[0019] The upper surface portion 23 has an upper surface protruding portion 23a that protrudes toward the base member 10 side further than the back surface portion 25. A locking portion 23b that locks into the lock receiving portion 12a of the base member 10 and a positioning portion 23c that engages with the positioning engagement portion 12b are protrudingly provided on the back surface side of the upper surface protruding portion 23a.

[0020] The locking portion 23b in this embodiment has a cylindrical bulge 23d at its tip. The bulge 23d is adapted to come into contact with the inner circumferential surface of the locking receiving portion 12a, more specifically, with the retaining portion 12d of the locking receiving portion 12a, when the handrail member 20 is attached to the base member 10.

[0021] The retaining portion 12d in this embodiment is provided at a position that cancels the moment that occurs in the locking portion 23b of the handrail member 20 when a downward load is applied to the handrail member 20. In other words, the moment that occurs in the locking portion 23b when a downward load is applied to the handrail member 20 is canceled by the bulging portion 23d of the locking portion 23b abutting against the retaining portion 12d, preventing the locking portion 23b from falling off from the lock receiving portion 12a.

[0022] The positioning portion 23c in this embodiment is composed of a hemispherical protrusion in cross section. The positioning portion 23c is provided at a position where it fits into the positioning engagement portion 12b when the locking portion 23b is locked into the lock receiving portion 12a. In other words, the distance between the locking portion 23b and the positioning portion 23c of the handrail member 20 is set to be equal to the distance between the lock receiving portion 12a and the positioning engagement portion 12b.

[0023] The bottom surface portion 24 has a bottom surface protruding portion (handrail-side second contact portion) 24a that protrudes toward the base member 10 side further than the back surface portion 25. The bottom surface protruding portion 24a in this embodiment has a downward inclined surface 24b that is placed on the outer side (lower side in the figure) of the upward inclined surface 13a.

[0024] 4(b), in this embodiment, a first lighting installation section 26 for installing a lighting device is provided on the base side of the handle section 21 of the top surface section 23, and an LED (first light source) 26a and a light-transmitting plate (first light-transmitting plate) 26b are provided. Similarly, a second lighting installation section 27 is provided on the base side of the bottom surface protruding section 24a of the bottom surface section 24, and an LED (second light source) 27a and a light-transmitting plate (second light-transmitting plate) 27b are provided.

[0025] The first lighting installation portion 26, the second lighting installation portion 27, the LEDs 26a, 27a and the light-transmitting plates 26b, 27b mounted thereon may be provided as necessary, and may be omitted if unnecessary.

[0026] Next, the procedure for installing the handrail 30 of this embodiment will be described. (1) The fixing portion 11 of the base member 10 is placed at a predetermined position on the mounting surface, and the fixing portion 11 is fixed at a plurality of points in the longitudinal direction with fasteners 41 (FIG. 5(a)). (2) From the state of (1) above, insert the locking portion 23b of the handrail member 20 into the locking receiving portion 12a of the base member 10 fixed to the mounting surface (Fig. 5(a)). At this time, as shown in Figs. 5(a) and (b), lift the handrail member 20 obliquely so that the handle portion 21 side of the handrail member 20 is higher, and insert the locking portion 23b into the locking receiving portion 12a from above obliquely. (3) From the state of (2) above, the handle portion 21 side of the handrail member 20 is lowered (FIG. 6(a)) so that the locking portion 23b abuts against the inner circumferential surface of the retaining portion 12d of the lock receiving portion 12a. (4) From the state (3) above, the handle portion 21 side of the handrail member 20 is further lowered, and the locking portion 23b is brought into contact with the inner peripheral surface of the anti-slip portion 12d of the locking receiving portion 12a, while the downward inclined surface 24b of the bottom surface protrusion portion 24a is aligned with the outside of the upward inclined surface 13a, and the upward inclined surface 13a and the downward inclined surface 24b are fixed with the fastener 41 (Figure 6(b)).

[0027] When a downward force is applied to the handle portion 21 of the handrail 30 attached as described above, the locking portion 23b abuts against the inner peripheral surface of the retaining portion 12d of the lock receiving portion 12a, and the downward inclined surface 24b of the bottom surface protrusion portion 24a abuts against the upward inclined surface 13a, preventing the handrail member 20 from falling off the base member 10. In addition, the positioning portion 23c engages with the positioning engagement portion 12b, preventing the handrail member 20 from shifting in the front-to-rear direction (the direction intersecting the longitudinal direction of the handle portion 21).

[0028] In the handrail 30 of this embodiment, a positioning engagement portion 12b is provided on the base member 10 in addition to the locking receiving portion 12a, and a positioning portion 23c is provided on the handrail member 20 in addition to the locking portion 23b. The position of the handrail member 20 can be determined simply by locking the locking portion 23b into the locking receiving portion 12a and engaging the positioning portion with the positioning engagement portion 12b, making it easier to install than conventional handrails.

[0029] (Other embodiments) In the above embodiment, the locking portion 23b, the locking receiving portion 12a, the positioning portion 23c, and the positioning engaging portion 12b are, for example, long grooves or protrusions in the longitudinal direction, but the locking portion 23b, the locking receiving portion 12a, the positioning portion 23c, and the positioning engaging portion 12b may be configured as short grooves (including dot-like depressions) or short protrusions provided at intervals, etc. However, even in this case, it is necessary to configure the locking portion 23b and the locking receiving portion 12a to lock, and the positioning portion 23c and the positioning engaging portion 12b to engage.

[0030] In the above embodiment, the upper surface protruding portion 23a of the handrail member 20 covers the outside of the upper protruding portion 12 of the base member 10 as an example, but the upper surface protruding portion 12 of the base member 10 can also be configured to cover the outside of the upper surface protruding portion 23a of the handrail member 20. In this case, the locking portion 23b and the positioning portion 23c are provided on the front surface (upper surface) of the upper surface protruding portion 23a, and the locking receiving portion 12a and the positioning engaging portion 12b are provided on the back surface of the upper protruding portion 12.

[0031] In the above embodiment, an example is given in which the downward inclined surface 24b of the bottom surface protrusion 24a is configured to abut against the outer side of the upward inclined surface 13a of the lower protrusion 13, but it is also possible to configure the upward inclined surface 13a of the lower protrusion 13 to abut against the outer side of the downward inclined surface 24b of the bottom surface protrusion 24a.

[0032] In the above embodiment, an example is given in which the locking receiving portion 12a and the positioning engaging portion 12b are grooves, and the locking portion 23b and the positioning portion 23c are protrusions, but the locking receiving portion 12a and the positioning engaging portion 12b can also be protrusions, and the locking portion 23b and the positioning portion 23c can also be grooves.

[0033] In the above embodiment, the base member 10 and the handrail member 20 are made of aluminum, but the base member 10 and the handrail member 20 may be made of materials other than aluminum. For example, they may be made of various materials such as resin, wood, stainless steel, and iron. In some cases, the core material made of various materials such as aluminum, stainless steel, and iron may be a resin molded product or one coated with a coating agent (a coating agent of a resin material, a rubber material, or the like).
