DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is particularly applied to a wall of a building, such as a hospital or a nursing home, or a wall of an elevator.
The present invention relates to a guard rail for installing a wall surface for protecting a wall surface against collision of an indoor vehicle such as a stretcher.

[0002]

2. Description of the Related Art The present invention is an improved invention of a guard rail for wall installation described in Japanese Patent Application No. 8-316925 previously invented by the present inventor. The guardrail according to the previous invention has the cross section shown in FIG. The installation of this guardrail on the wall is
The upper hook-shaped edge 24 of the covering member 11 is locked to the upward protruding edge of the skeleton member 1 fixed to the installation wall surface A, and the lower hook-shaped edge 25 of the covering member is then locked to the lower protruding edge of the skeleton member. And covering member 1
1 is fitted to the skeletal member 1.
However, since the covering member 11 is a long object, when the sole installer performs installation, the covering member must be sequentially fitted from one end of the skeletal member 1 attached to the wall surface. As shown in the figure, since the unfitted covering member 11 is lowered toward the floor, the upper edge of the covering member once fitted to the upward protruding edge of the skeletal member 1 is held as shown by a broken line. Since there is a possibility that the downward hook upper edge 24 of the covering member 11 may fall off from the upward projection edge of the skeletal member, the fitting operation must be continued while constantly pressing the corresponding portion from above. A situation has arisen in which skills with considerable fatigue are required and the workability is not good.

[0003] The operation of locking the lower hook-like edge 25 of the covering member to the downward protruding edge of the skeletal member is performed by the following method.
It is necessary to insert the tip of the thin lower hook-shaped edge 25 into the gap formed by the wall surface and the downward protruding edge while performing a delicate operation at a place where it is difficult to see from the outside. Such an unfinished portion in the locked state tends to occur (the broken line position is a regular locking position), and even if such an unfinished portion occurs, it may be overlooked.

[0004]

The adhesive can be used effectively.

[0016]

The present invention has the following effects. A. When performing a fitting work for sequentially covering the long covering member from one end to the long skeleton member fixed to the installation wall surface, since the covering member before mounting is placed on the floor surface, An unfitted covering member is in a state of being lowered from the already fitted portion toward the floor surface, and is in an upward direction such that the fitting of the covering member at the already fitted portion which is continuous with the unfitted portion is released. Although the lifting stress acts, even if such a stress acts to lift the covering member at the already-fitted portion, the upper surface of the ridge for preventing falling off comes into contact with the upper edge of the groove of the skeleton member. The lifting displacement is stopped, and at that position, the hook-like edge of the covering member holds the engagement state with the upward protruding edge of the skeleton member, so that the stopping state of the lifting displacement is maintained and the covering member falls off. There is no danger of doing this. Therefore, even a single worker is free from the troublesome and excessive work of pressing the already-fitted portion against the skeletal member and performing the fitting work while preventing the work from falling off, and can easily and quickly proceed with the work. be able to.

B. The arrow cross-section ridge formed on the rear surface of the covering member is provided at a position facing the widened groove of the skeleton member when the hook-shaped edge of the covering member reaches a predetermined fitting state with the upward protruding edge. Therefore, if the lower portion of the covering main body portion is pressed against the installation wall surface as it is, it is securely fitted into the expanded groove of the skeleton member. At the time of fitting, the arrow cross-section ridge is difficult to see from the worker side, but since the arrow cross-section ridge has a sharp tip, even if there is a slight positional error, the fitting is reliably performed only by pressing, Since the response of the fitting is sufficiently transmitted to the operator, delicate installation work is not required. Since the worker does not need to touch the installation wall through the operation of fitting the covering member to the skeleton member, the installation operation can be performed without soiling the installation wall. C. The attachment of the end cap is performed by applying an adhesive between the back surface of the end outer shell and the covering member, but when the end cap made of a hard material is attached, the end outer shell of the end cap is attached. The end portion of the covering member is pinched by the end holding projection and the covering member is in close contact with the skeletal member, and even when the end cross-sectional shape of the covering member is deformed by this close contact, Since the cross-sectional shape is corrected, the gap between the bonding surfaces is not only reliably removed, but also the bonding reaction proceeds in a pressed state, so that the adhesive can be used effectively. D. The attachment of the corner cap is performed by applying an adhesive between the back surface of the corner outer shell and the covering member, but when the corner cap made of a hard material is attached, the corner outer shell of the corner cap is attached. The end portion of the covering member is sandwiched between the cover member and the corner holding projection, so that the covering member is in close contact with the skeletal member, and even if the end section of the covering member is deformed due to this close contact. In addition, since the cross-sectional shape is corrected, the gap between the bonding surfaces is not only reliably removed, but also the bonding reaction proceeds in a pressed state, so that the adhesive can be effectively used.
