Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a guard rail installed on walls of hallways and stairs in buildings, passage walls of large mechanical equipment, and even walls of elevators.

Conventionally, this type of guard rail mainly consists of a guardrail main body and a support part to which the guardrail main body is attached, that is, a bracket fixed to a wall or panel, and the guardrail main body is strongly pressed against the surface of this bracket and assembled. Those with the following were used.

These guardrail bodies had a rectangular upper end, and had approximately the same thickness from the upper end, so that the entire body had a rectangular shape extending vertically (for example,
16412).

Therefore, it can function as a guard rail to protect the wall and objects that collide with it.
Since the entire handle had the same thickness, it was difficult to grip and could not function as a handrail.

Furthermore, there are some models with an arcuate upper end, but like the rectangular ones mentioned above, the thickness is the same from top to bottom, so the disadvantage of being difficult to grip cannot be eliminated.
In particular, it was unsuitable for installation in hallways such as hospitals, which require both a grip function as a handrail and a protection function against collisions.

An object of the present invention is to prevent excessive deformation due to the elasticity of the guardrail body and to exhibit a buffering effect on a guardrail body and a bracket, each of which has a grip portion formed at its upper end that can be easily grasped by a pedestrian. A guard that absorbs and alleviates impact force through lateral displacement of the guardrail body, and when the guardrail body is assembled to the bracket, prevents deformation of the guardrail body so that it is smoothly guided to the bracket and assembled in an elastically connected state. It provides rails.

Preferred specific examples of the guard rail according to the present invention will be described below with reference to the drawings.

1 to 4 show a tenth embodiment of the guard rail of the present invention installed in a hospital hallway.

The guard rail 10 has a support, i.e. a wall 6, in the corridor, as shown in FIG.
It is attached so as to protect the wall surface 61 of 0.

The guard rail 10 includes a guard rail main body 11 arranged on a wall surface 61 at a predetermined height from the floor of the hallway and extending in the length direction, and a guard rail main body 11 arranged at appropriate intervals so that the guard rail main body 11 is attached to the wall surface 61. A bracket 12 is screwed to a large number of fixing rods 50 fixed to a wall surface 61.
and a pair of cushioning materials arranged on the surface of the bracket 12 and pressed against the back surface of the guardrail body 11.

As shown in FIG. 1, the guardrail main body 11 is formed by extrusion molding a hard synthetic resin with low foaming, and has an upper end of a substantially vertical rail main body 14 extending in the length direction of the guard rail 10. for,
A grip portion 15 having a substantially inverted U-shape in cross section is integrally formed, and the grip portion 15 has an arcuate outer surface;
Top portion 15 whose back surface is a substantially smooth sliding surface 19
a, and substantially vertical inner and outer side walls 15, 15b vertically disposed on both sides thereof,
The outer side wall 15b continues from the rail main body 14 in a slightly bulged outward state, and an upper hook 17 is formed at the lower end of the inner side wall 15c. A lower hook 18 that projects laterally is integrally formed at the lower end of the rail body 14.

The bracket 12 to which the guardrail main body 11 is attached is extruded into a long piece from an aluminum alloy and has the cross-sectional shape shown in FIG.
4, the substantially vertical mounting web 20 extends in its length direction and is fixed to the support part, that is, the wall surface 61 of the wall 60. At the upper and lower ends of the mounting web 20, there are inner side walls of the grip part 15. 15c and the upper and lower hooks 17, 18 formed at the ends of the rail main body 14 to form upper and lower lips 22, 23 that snap into engagement with the upper and lower hooks 17, 18,
The upper lip 22 has a curved shape that is pressed in the vertical direction on the substantially smooth sliding surface 19 formed on the back surface of the top 15a of the grip part 15 and that can be slid laterally in the pressed state. A grip portion receiver 21 having a support edge 29 on its upper end side is formed in an upright shape.

The grip portion receiver 21 has a supporting edge 2 on its upper end side.
9 is curved toward the surface side of the mounting web 20, and the leading edge thereof passes through the center of the grip portion 15, that is, the center of curvature of the grip portion 15.
The guardrail main body 11 is positioned backward from the parallel imaginary line toward the wall surface, and the guardrail main body 11 is located behind the bracket 12.
It is formed so that it comes into pressure contact with a substantially smooth sliding surface 19 when assembled.

The bracket 12 also has its mounting web 2
A guide wing 26 is formed on the lower side edge of the guardrail body 11 to project toward the guardrail body 11 side, and this guide wing 26 is provided with a sliding surface 30 whose outer surface is an inclined curved surface, and the guardrail body 11 is assembled to the bracket 12. At this time, the lower hook 18 of the guardrail body 11 is smoothly guided to the lower lip 23, and the lower hook 18 is easily engaged with the lower lip 23 in a snap-like manner, thereby preventing excessive deformation of the guardrail body 11. .

Further, in order to easily attach the bracket 12 to the fixing rod 50, the brackets 12 are arranged at predetermined intervals in the vertical direction.
A pair of positioning ribs 2 extending in the length direction
7 and 28 are formed protruding from the back surface of the mounting web 20.

A pair of horizontally opened fitting grooves 24 and 25 are formed on the surface side of the mounting web 20 for fixing the cushioning material 13 which is elastically pressed against the guardrail body 11 and supported by the bracket 12. .

The pair of fitting grooves 24 and 25 are formed in a flanged channel, and are arranged vertically within the width of the rail main portion 14 of the guardrail main body 11.
The openings extend in the length direction at predetermined intervals and are laterally opened on the surface of the attachment web 20.

A pair of fitting grooves 2 formed in the bracket 12
The cushioning materials 13, 13 fitted into the cushioning materials 4, 25 have the cross-sectional shape shown in FIG. 1 and are extruded from soft synthetic resin, semi-hard synthetic resin, or rubber.
A hollow part 31 is provided to improve the cushioning effect.

This cushioning material 13 has grooves 32 and 33 extending in the length direction on both sides and openings, which engage the flange portions of a pair of fitting grooves 24 and 25 provided in the bracket 12 to prevent them from coming off. It is prevented.

A method for attaching the guard rail 10 will be explained based on FIGS. 1 to 4. First, position the guard on the wall 61 of the hallway wall 60.
A large number of fixing rods 50 are fixed to the wall surface 61 at appropriate intervals in the length direction of the rail 10 using concrete bolts (not shown).

Next, the bracket 12 is passed between the fixing rods 50 and screwed, and then the fitting groove 2 of the bracket 12 is inserted.
The cushioning materials 13 and 13 are fitted into the holes 4 and 25, respectively. Note that this cushioning material 13 can also be attached to the bracket 12 in advance at the factory.

Subsequently, as shown in FIG.
Hook the upper hook 17 provided on the upper lip 22 of the bracket 12, and
The guardrail main body 11 is placed on the bracket 12 so that the guardrail body 11 is in contact with the buffer material 13 on the upper side.

In such a state, as shown in FIG. 3, the upper cushioning material 13 is slightly crushed and the guardrail body 11 is moved so that the lower hook 18 formed at the tip of the flange 16 contacts the guide wing 26. Press it against the bracket 12. Furthermore, the guardrail main body 11 is pressed against the bracket 12 so as to crush the upper and lower cushioning materials 13, 13, and the lower hook 18 is moved along the guide wing 26 to the state shown in FIG. 4.

In the state shown in FIG.
Since the flange 16 is elastically deformed relative to the rail main body 14, it engages with the lower lip 23 in a snap-like manner.

In this state, the grip portion receiver 21 has its curved support edge 29 aligned with the top portion 15a of the grip portion 15.
is pressed upwardly to a substantially smooth sliding surface 19 formed on the back surface of the
The upper hook 17 and the upper lip 22 are engaged with each other while preventing excessive deformation that is likely to occur in the guardrail body 11, especially in the grip portion 15 thereof.

Furthermore, when the guardrail main body 11 is hooked from the lower hook 18 to the lower lip 23 from the state shown in FIG.
As a result, the guardrail main body 11 is moved forward and installed in the assembled state shown in FIG.

At this time, the curved support edge 29 of the grip portion receiver 21
is pressed against the substantially smooth sliding surface 19 of the grip portion 15 and slides in the lateral direction, and the upper and lower hooks 17,
18 and the upper and lower lips 22, 23 are maintained in engagement.

With the guardrail body 11 attached and fixed to the bracket 12, an end cap, corner cap, or joint cap (none of which is shown) is attached to the side end of the guardrail body 11 or between adjacent guardrail bodies 11, 11. .

When the guardrail body 11 assembled to the bracket 12 as described above receives an impact or pressure on its surface side, it moves laterally, that is, toward the wall, while crushing the cushioning material 13 interposed between it and the bracket 12. The grip part 15 is displaced as a whole.
Since the curved support edge 29 of the grip portion receiver 21 is always in pressure contact with the substantially smooth sliding surface 19 of the bracket 12 and slides along with it, the bracket 12 and the guardrail body 11 are elastically connected. can be retained.

As explained above, according to the guard rail of the present invention, the guard rail main body has an arcuate top portion, inner and outer side walls on both sides, and a grip formed in a substantially inverted U-shape in cross section. The part of the rail is located slightly bulging outward from the main part of the rail.
It maintains the impact action caused by the elastic deformation of the guardrail body to reduce the impact during a collision and protect the human body and the object it collides with.It also prevents damage to the wall surface due to a collision. Since it is formed in a slightly bulging shape, a pedestrian can easily grasp this grip part and use it for support.

In addition, the substantially smooth sliding surface formed on the back surface of the top of the grip and the curved support edge formed on the upper end of the grip receiver are always in pressure contact with each other in the vertical direction, and in this pressed state, in the lateral direction. Since it is slidably assembled to the handle, the top part is formed to be slightly thick against pressure from the upper side that is applied to the grip part.
In addition, it is stiffened by the pressure contact between the sliding surface on the back side and the supporting edge, which prevents large deformation of the guardrail body, and also prevents shocks and pressure from acting from the front side of the slightly bulging grip part. The sliding surface and the support edge follow the deformation and displacement caused by pressure contact, absorbing and relaxing it and restoring it.Also, when the guardrail body is assembled to the bracket, the deformation is restricted and the guardrail is smoothly guided to the bracket. and can be easily assembled.

Furthermore, the guardrail body and the bracket can be maintained in an elastically connected state by snap-like engagement of the upper and lower hooks with the cushioning material provided on the surface side of the bracket and its upper and lower lips. can.
