Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bracket for a wall-mounted handrail that is attached to a wall such as a staircase or a hallway, and in particular, it relates to a bracket for a handrail that is attached to a wall such as a staircase or a hallway. Relating to a bracket for a wall-mounted handrail that allows adjustment of the joining angle, firmly connects the two, and prevents the support arm fixed to the headboard from getting in the way when the hand slides along the headboard. .

The present inventors have developed a bracket for this type of wall-mounted handrail, in which a support member fixed to the wall surface and a support arm fixed to the Kasagi side are connected by fastening. A protrusion protruding toward the surface side is formed, and a connecting hole penetrating in the direction of the protrusion is formed in the protrusion, and a fixing part fixed to the cap is provided on the upper part of the support arm, and the support arm is provided with a fixing part fixed to the cap. A connecting portion having a through hole is formed in the lower part of the arm, and fitting portions are formed on the tip side of the protruding portion and on the back side of the connecting portion, respectively, so that the connecting angle can be adjusted and fit into each other. By adjusting the connection angle between the body and the support arm, it is possible to accommodate caps installed at various slopes, and at the same time, by strengthening the bond between the two, it is also possible to accommodate caps made of elastic material. Invented a bracket for a wall-mounted handrail (Showa era).
Patent application (1) filed on March 26, 1959).

This invention relates to an improvement of the bracket for a wall-mounted handrail according to the above-mentioned invention, and in particular, it employs bolts and nuts that can achieve an inexpensive and strong connection as a connecting means between the support body and the support arm, and furthermore, To provide a bracket for a wall-mounted handrail which can be easily tightened exclusively from the surface side of the bracket.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

1 to 3, a bracket B of a wall-mounted handrail according to a first embodiment of the present invention is shown. This bracket B consists of a support 1 fixed to a wall W side such as a staircase or a hallway, a support arm 2 fixed to a Kasagi H side, and a bolt 3 that connects these supports 1 and support arms 2 to each other. and nut 4. The support body 1 is formed with a protrusion 5 that protrudes toward the surface thereof, and this protrusion 5 is formed with a connecting hole 6 that penetrates in the direction of the protrusion. A concave fitting part 7a that is concentric with the connecting hole 6 and has a larger diameter than the connecting hole 6 is formed on the tip side, and a connecting hole formed in the protruding part 5 is formed on the back side of the support 1. A hexagonal locking groove 8 is formed which communicates with the nut 6 and prevents the nut 4 from rotating when the nut 4 is fitted. Further, a fixing part 9 having a substantially U-shaped cross section is formed on the upper part of the support arm 2, and this fixing part 9 holds the lower part of the outer circumference of the Kasagi H. is a connecting part 1 having a through hole 10
1 is formed on the back side of the connecting portion 11, and is concentric with the through hole 10 and has a larger diameter than the through hole 10, and is rotatably fitted into the fitting portion 7a of the protruding portion 5. A convex fitting part 7b is formed, and a recess 12 is formed on the surface side of the connecting part 11, and is concentric with the through hole 10 and has a larger diameter than the through hole 10. The head of the bolt 3 that is screwed into the nut 4 that passes through the through hole 10 and the connecting hole 6 and is fitted into the locking groove 8 formed on the back side of the support body 1 is buried. There is.

In this first embodiment, the depth d of the locking groove 8 into which the nut 4 is fitted is approximately equal to the thickness of the nut 4, and at least the opening edge of the locking groove 8 and the support The bolt 3 is inserted into the through hole 10 and the connecting hole 6, and the threaded part is screwed into the nut 4. Even if the nut 4 is pressed by the bolt 3 during fitting, the back surface of the nut 4 comes into contact with the wall surface W, so that the nut 4 does not come off from the locking groove 8.

Next, in the bracket B of the wall-mounted handrail of the second embodiment shown in FIG. A cap nut 4a is screwed into the threaded portion of the hexagonal bolt 3a from the surface side of the connecting portion 11 of the support arm 2.

Furthermore, in the bracket B of the wall-mounted handrail of the third embodiment shown in FIGS. 5 and 6, unlike the above-mentioned embodiments, the bolt 3c is rotatable at its tip in a position offset to one side from the center. It has a locking pin 13 that is pivotally supported by the locking pin 13 and has a threaded portion at the other end, and the tip side where the locking pin 13 is provided is connected from the surface side of the connecting portion 11 to its through hole 10 and the support body 1. into the connecting hole 6 of the protrusion 5 of the support body 1.
The locking pin 13 is rotated by its own weight in the vertical locking groove 8 formed on the back side of the bolt 3c, and when the locking pin 13 becomes approximately perpendicular to the axis of the bolt 3c, the connecting portion is closed. Bolt 3c from the front side of 11
A nut 4 is screwed onto the threaded portion of the connecting portion 11 , and by tightening the nut 4 , the locking pin 13 is locked and fixed to the opening edge of the connecting hole 6 of the protruding portion 5 .
The threaded portion of the bolt 3c and the nut 4 located in the recess 12 formed on the surface side of the bolt 3c are hidden by the cap 14. According to this third embodiment, the support body 1 is first fixed to the wall surface W, and then the back surface of the connecting portion 11 of the support arm 2 is inserted into the fitting portion 7a formed on the surface side of the protruding portion 5 of the support body 1. The fitting part 7b formed on the side is fitted, and the connecting part 1
The support arm 2 can be fixed to the support body 1 by inserting the bolt 3c from the surface side of the support arm 1 and tightening it with the nut 4.

As described above, the bracket of the present invention secures the necessary space between the wall surface and the capstone by the protrusion provided on the surface side of the support, and also provides a connecting hole in the protrusion. A through hole is provided in the connecting part of the support arm, and the through hole and the connecting hole are used to connect the parts with bolts and nuts so that the joining angle can be adjusted.Furthermore, the tip side of the protruding part and the back side of the connecting part are fitted with each other. By forming mating fitting parts to increase the contact area between the two, the joint strength is high when joined with bolts and nuts, and not only can the Kasagi be fixed to the wall at a predetermined angle, but it can also be attached to connecting holes and through-holes. All of these holes need to be blank holes, and the work of drilling these connecting holes and through holes in the protruding parts of the support body and the connecting parts of the support arms becomes extremely easy, and the manufacturing cost of the bracket can be significantly reduced. .

In each of the above embodiments, a fixing part 9 having a substantially U-shaped cross section is formed at the upper part of the support arm 2, and is formed to be able to hold the lower part of the outer periphery of the Kasagi H having an oval cross-section. The shape of the portion 9 is not limited to that in the above embodiment, and can be changed as appropriate in consideration of the cross-sectional shape of the cap H. In addition, the fitting parts 7a and 7b formed on the tip side of the protruding part 5 and the back side of the connecting part 11, respectively, differ from the above embodiments in that the fitting part 7a is formed in a convex shape, and the fitting part 7a is formed in a convex shape. Of course, the portion 7b may be formed in a concave shape.
