Description

The present invention relates to a handrail that is attached to various mounting surfaces such as walls and doors, and more specifically to a handrail that uses a base member that is attached to the mounting surface and a handrail member that is attached to the base member.

A handrail that can be attached to a mounting surface such as a wall or door is known to have a long base member that is attached to the wall and a handrail member that is fixed to the base member (Patent Document 1). This handrail is configured so that the fitting portion of the handrail member fits into a groove in the base member, and the two are fixed together by screwing the fitting portion.

JP 2006-77516 A

However, with a structure in which the fitting part on the handrail member is simply fitted into a groove on the base member, there is a possibility that the fitting part that fits into the groove may become misaligned or the handrail member may come off the base member until it is screwed in place, and there is room for improvement in this regard.

The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a handrail that is easier to install than conventional handrails that include a base member and a handrail member.

[Base member]
The base member in this application is a long base member to which a handrail member having a handle portion is attached, and is provided with a fixing portion which is fixed to the mounting surface, a locking receiving portion into which the locking portion of the handrail member locks, and a positioning engaging portion into which the positioning portion of the handrail member engages.

[Handrail components]
The handrail member in this application is a long handrail member that is attached to a base member for a handrail, and is provided with a locking portion that locks into the locking receiving portion of the base member, and a positioning portion that engages with the positioning engagement portion of the base member.

[handrail]
The handrail of the present invention is a handrail comprising a base member and a handrail member attached to the base member, in which the base member is the base member defined in the present application , and the handrail member is the handrail member defined in the present application .

In the present invention, a positioning portion and/or a positioning engagement portion are provided in addition to the locking portion and locking receiving portion, so the handrail member locked to the base member is less likely to shift position, and is easier to install than conventional handrails.

(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 Figures 1 and 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.

The base member 10 is a member for fixing the handrail member 20, and is fixed to various mounting surfaces such as walls and doors. In this embodiment, the base member 10 is a long member that is U-shaped in cross section and includes a fixing portion 11 that is fixed to the mounting surface, an upper protrusion (base side first abutment portion) 12 and a lower protrusion (base side second abutment portion) 13 that protrude from the surface of the fixing portion 11 opposite the surface facing the mounting surface.

As shown in Figures 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 on its upper surface is provided a locking receiving portion 12a that engages with a locking portion 23b (described later) and a positioning engaging portion 12b that engages with 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.

The locking receiving portion 12a in this embodiment has a longitudinally elongated groove portion 12c and a retaining portion 12d provided on the upper periphery of the groove portion 12c, and the locking portion 23b (Fig. 3(b)) that fits into the groove portion 12c abuts against the retaining portion 12d, so that the handrail member 20 is held in the base member 10. The groove portion 12c has a clearance 12e (Figs. 6(a)(b)) that allows the fitted locking portion 23b to move inside the groove portion 12c.

The positioning engagement portion 12b is the portion that engages with the positioning portion 23c (FIG. 3(b)) described below. 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 locking receiving portion 12a. In other words, the distance between the locking 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.

The lower protruding portion 13 is a long plate having a length similar to that of the fixing portion 11, and has an upwardly inclined surface (base-side inclined surface) 13a that slopes obliquely upward on the tip side. This upwardly inclined surface 13a is a surface that engages with a downwardly inclined surface (handrail-side inclined surface) 24b (FIGS. 3(b) and 4(b)) of the handrail member 20 described later, supporting the upward force acting on the downwardly inclined surface 24b, and is a surface for fixing a stopper 41 used to fix the base member 10 and the handrail member 20.

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

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 top surface portion 23 and the bottom surface portion 24 in a direction facing the front portion 22.

The top surface 23 has a top surface protrusion 23a that protrudes toward the base member 10 side from the back surface 25. On the back surface side of the top surface protrusion 23a, a locking portion 23b that locks into the locking receiving portion 12a of the base member 10 and a positioning portion 23c that engages with the positioning engagement portion 12b are protruding.

In this embodiment, the locking portion 23b has a cylindrical bulge 23d at its tip. The bulge 23d is designed to abut against the inner circumferential surface of the locking receiving portion 12a, more specifically, against the retaining portion 12d of the locking receiving portion 12a, when the handrail member 20 is attached to the base member 10.

The retaining portion 12d in this embodiment is located in 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 bulge 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.

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 that 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.

The bottom surface portion 24 has a bottom surface protrusion portion (handrail side second abutment portion) 24a that protrudes toward the base member 10 side from the back surface portion 25. In this embodiment, the bottom surface protrusion portion 24a has a downward inclined surface 24b that is placed on the outer side (lower side in the figure) of the upward inclined surface 13a.

As shown in FIG. 4(b), in this embodiment, a first lighting installation section 26 for installing a lighting device is provided at 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 at the base side of the bottom surface protrusion 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.

The first lighting installation section 26, the second lighting installation section 27, the LEDs 26a, 27a and the light-transmitting plates 26b, 27b mounted thereon may be provided as needed, and may be omitted if not required.

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 peripheral surface of the retaining portion 12d of the locking 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 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 placed against the outside of the upward inclined surface 13a, and the upward inclined surface 13a and the downward inclined surface 24b are fixed with the stopper 41 (Figure 6 (b)).

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 locking receiving portion 12a, and the downward inclined surface 24b of the bottom surface protrusion 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).

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

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 with each other.

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

In the above embodiment, the downwardly inclined surface 24b of the bottom protrusion 24a is configured to abut against the outer side of the upwardly inclined surface 13a of the lower protrusion 13, but it can also be configured so that the upwardly inclined surface 13a of the lower protrusion 13 abuts against the outer side of the downwardly inclined surface 24b of the bottom protrusion 24a.

In the above embodiment, the locking receiving portion 12a and the positioning engaging portion 12b are grooves, and the locking portion 23b and the positioning portion 23c are ridges, but the locking receiving portion 12a and the positioning engaging portion 12b can also be ridges, and the locking portion 23b and the positioning portion 23c can also be grooves.

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 may be made of various materials such as aluminum, stainless steel, and iron, and may be coated with a resin molded product or a coating agent (a coating agent such as a resin material or a rubber material).

The above embodiment is an example, and the base member 10 and the handrail member 20 in the present application, and the handrail 30 of the present invention are not limited to the configuration of the above embodiment. The base member 10 and the handrail member 20 in the present application, and the handrail 30 of the present invention can be modified, replaced, omitted, or otherwise altered in configuration, without departing from the spirit of the present invention.

The base member 10 and handrail member 20 in this application, as well as the handrail 30 of the present invention, can be used as handrails 30 installed indoors, such as in corridors, rooms, stairs, bathrooms, and toilets, as well as outdoors, such as in train stations, commercial facilities, and stadiums, and can be particularly suitably used as a walking aid handrail that pedestrians can hold onto while walking.
