  With such a mounting method, not only the handrail mounting bracket fixed to the wall surface or other attached object with screws can be seen as it is, but also the screw for fixing the handrail mounting bracket to the attached object or the handrail mounting. The screw for fixing the handrail to the bracket is also visible, so the appearance after construction is bad. Further, since the handrail mounting bracket can be seen as it is, the handrail mounting bracket must be made so expensive and must be excellent in design.

In order to eliminate such drawbacks, in the present invention, the handrail bracket A can be attached to the handrail stopper 1 that can be attached to the wall surface to which the handrail B is to be attached and other attachments C, and the handrail B, The bracket 4 is configured to be fitted to the handrail stopper 1 and cover the periphery thereof.
When the handrail bracket A is used, when the handrail B is attached to the wall or other attached object C, the handrail stopper 1 attached to the wall or other attached object C is covered with the bracket 4. Because it is not visible, you can construct handrails that look good. Moreover, since the screw E for fixing the handrail stopper 1 and the bracket 4 and the screw F for fixing the bracket 4 and the handrail B are not visible, a handrail having a better appearance can be constructed.

When fitted to the handrail stopper 1, it is preferable that the recess 4a and the insertion hole 4b of the bracket 4 into which the handrail stopper 1 is inserted are horizontally long.
When this handrail bracket A is used, even if the mounting position of the bracket 4 to which the handrail B is fixed is slightly deviated from the handrail stopper 1 attached to the wall surface or other attachment object C, the error Can be absorbed by the horizontally long recess 4a and the insertion hole 4b, so that the work of attaching the bracket 4 and the handrail B to the handrail stopper 1 can be easily performed.

A screw hole penetrating in the vertical direction is formed in the handrail stopper 1, and a screw E screwed into the screw hole engages with a screw hole 3 b on the side penetrating and protruding from the handrail stopper 1. It is preferable not to engage with the screw hole 3a on the side to be screwed.
When this handrail bracket A is used, there are variations in the processing accuracy of the handrail stopper 1 and the bracket 4 which are constituent members thereof, and the screw hole 3a of the handrail stopper 1 and the screw hole 4a of the bracket 4 are attached at the time of mounting. Even if there is a slight shift, the wall surface or other attachment object C is soft, and the handrail stopper 1 to be attached to the wall bites into the attachment object C by tightening the screw, so that the screw hole 3a of the handrail stopper 1 is provided. Even if the screw hole 4a of the bracket 4 is slightly deviated, the screw hole 3a which is a large hole absorbs the error, so that the handrail B can be easily attached to the wall surface or other attachments C.

It is a figure which shows an example of the main components of the handrail bracket by this invention, (a) is a perspective view, (b) is the sectional drawing. It is a perspective view which shows the state which attached the handrail bracket shown in FIG. 1 to the to-be-attached object which is a wall surface on the side of stairs at predetermined intervals. It is a cross-sectional view which shows the state which fixed the bracket to the handrail with the screw. It is sectional drawing which shows the state before attaching the bracket fixed to the handrail with a screw to the handrail bracket shown in FIG. 1 fixed to the to-be-attached object which is a wall surface. The bracket fixed to the handrail with a screw is fitted to the handrail bracket shown in FIG. It is sectional drawing which shows the state which attached the handrail to the thing. It is a perspective view which shows the state which installed the handrail in the to-be-attached object which is a wall surface next to stairs. Schematic for explaining the force acting on the bracket when a load is applied to the handrail when a screw is screwed into the screw hole penetrating in the vertical direction of the handrail bracket and the handrail is attached to the attachment object which is the wall surface. It is.

  An embodiment for carrying out the present invention will be described in detail with reference to the drawings. Here, the case where the elongate handrail B is attached to the to-be-attached object C which is the wall surface of a staircase using the handrail bracket A by this invention is mentioned as an example, and is demonstrated. And here, as shown in FIG. 1, the handrail bracket A can be attached to the handrail stopper 1 that can be attached to the attachment C and the handrail B, and is fitted to the handrail stopper 1. An example of a case comprising a bracket 4 capable of covering the periphery of the lever is illustrated.

  The handrail stopper 1 is provided with a mounting seat 2, and the mounting seat 2 is formed with two screw holes 2a symmetrically on the upper side and one on the center line on the lower side. By screwing the screw D into these screw holes 2a, 2a, the handrail stopper 1 can be attached to the attachment C, which is the wall next to the stairs, as shown in the right side of FIG. 4, FIG. 5, and FIG. .

A fixed arm 3 extends from the center position of the mounting seat 2, and screw holes 3 a and 3 b are formed in the fixed arm 3 so as to penetrate in the vertical direction. The fixed arm 3 may be solid, but here, the case where the fixed arm 3 is cylindrical is illustrated, so the screw hole on the side into which the screw E is screwed upward in the vertical direction is 3a, and the screw E is The description will be made assuming that the screw hole penetrating through and protruding from the fixed arm 3 is 3b.
Then, the size of the screw hole 3a on the side into which the screw E is screwed is made larger than the screw diameter of the large-diameter portion of the screw E, and the size of the screw hole 3b on the side through which the screw E protrudes, The screw diameter is smaller than the screw diameter near the tip of the screw E. Therefore, when the screw E is screwed into the screw holes 3a and 3b penetrating in the vertical direction from the lower side in the vertical direction, the screw hole 3a on the screwed side is not contacted at all, so that it is easy to screw in. On the other hand, the screw E engages with the screw hole 3b in the screw hole 3b on the side through which the screw E protrudes.

  The mounting seat 2 and the fixed arm 3 of the handrail stopper 1 may be manufactured integrally, or both may be manufactured separately and joined together by welding. In the former case, the cost of the product can be made relatively low, but the mold becomes extremely high. Conversely, in the latter case, the mold is relatively cheap, but the cost of the product is high.

  As shown in FIGS. 1 (a) and 1 (b), the bracket 4 that can be fitted to the handrail stopper 1 and cover the periphery of the bracket 4 has a partly recessed inner end surface thereof. FIG. 1 (b) shows a slightly horizontally long recess 4a into which one mounting seat 2 can be fitted, and a slightly horizontally long insertion hole 4b penetrating from the recess 4a to the other side at the center position. Thus, the screw hole 4c which reaches the insertion hole 4b from the lower surface is formed. The fixed arm 3 of the handrail stopper 1 can be fitted into the insertion hole 4b.

  As shown in FIG. 3, the bracket 4 can be fixed to the handrail B with a horizontal screw F. In this case, an insertion hole b communicating with the insertion hole 4b may be formed on the inner end surface of the handrail B. When the bracket 4 fixed to the handrail B is fitted to the handrail stop 1, the tip of the fixed arm 3 of the handrail stop 1 can be inserted into the insertion hole b.

  The handrail bracket A illustrated here has such a structure. When the handrail bracket A is used, when the handrail B is attached to the attachment C that is the wall surface next to the stairs, the handrail stopper 1 attached to the attachment C that is the wall surface next to the stairs is the bracket. Since it is covered with 4 and cannot be seen, it is possible to construct handrails with good appearance. In addition, since the screw E for fixing the handrail stopper 1 and the bracket 4 and the screw F for fixing the bracket 4 and the handrail B are not visible, a handrail having a better appearance can be constructed.

As shown in FIG. 1 (a), the bracket 4 illustrated here is formed with a horizontally long recess 4a and an insertion hole 4b into which the handrail stopper 1 is inserted when the bracket 4 is fitted to the handrail stopper 1. Yes.
When this handrail bracket A is used, even if the mounting position of the bracket 4 to which the handrail B is fixed is slightly deviated from the handrail stopper 1 attached to the attachment C that is the wall surface next to the stairs. Since the error can be absorbed by the horizontally long recess 4a and the insertion hole 4b, the work of attaching the bracket 4 and the handrail B to the handrail stopper 1 can be easily performed.

Here, screw holes 3 a and 3 b are formed so as to penetrate the handrail stopper 1 in the vertical direction, and the screw E screwed into both the screw holes 3 a and 3 b penetrates from the handrail stopper 1 and protrudes. The case where it engages with the screw hole 3b and does not engage with the screw hole 3a on the side screwed into the handrail stopper 1 is illustrated.
When this handrail bracket A is used, it is easy to screw the screw E into the screw holes 3a to 3b penetrating in the vertical direction. In addition, there is a variation in processing accuracy of the handrail stopper 1 and the bracket 4 which are constituent members of the handrail bracket A, and the screw hole 3a of the handrail stopper 1 and the screw hole 4a of the bracket 4 may be slightly shifted during mounting. Even if the handrail stopper 1 to be attached to the wall surface or the other attachment object C is soft, it bites into the attachment object C by tightening the screw, and the screw hole 3a of the handrail stopper 1 and the screw of the bracket 4 Even if the hole 4a is slightly deviated, the screw hole 3a, which is a large hole, absorbs the error, so that the handrail B can be easily attached to the wall surface or other attachments C.

The size of the screw holes 3a and 3b penetrating in the vertical direction will be described in more detail with reference to FIG. 7. When a load is applied to the installed handrail B, the line C On the upper side, a tensile force in the direction in which the bracket 4 is separated from the surface of the attachment C is applied, and on the lower side of the line O, a compression force in a direction in which the bracket 4 enters the surface of the attachment C is applied.
In this case, when a load is applied to the handrail B if the screw hole 3b on the side protruding through the handrail stopper 1 is larger than the screw diameter of the screw E and the screw E is not engaged with the screw hole 3b. A force in a direction away from the surface of the attachment C is applied to the bracket 4, and a gap is generated between the bracket 4 and the attachment C, resulting in poor appearance.
On the other hand, when the screw hole 3b on the side penetrating and projecting from the handrail stopper 1 is smaller than the screw diameter of the screw E and the screw E is engaged with the screw hole 3b, the bracket 4 has an object to be attached. A force in the direction of pressing against the C surface is applied, and no gap is generated between the bracket 4 and the attachment C, so that the appearance is good.

Next, construction work for attaching the handrail B to the attachment C, which is the wall surface next to the stairs, using the handrail bracket A will be described in detail below.
First, as shown on the right side of FIG. 4, the screw D is screwed into the screw hole 2a of the mounting seat 2 of the handrail stopper 1, and as shown in FIG. A handrail stopper 1 is attached to C. Next, as shown in FIG. 3, a bracket 4 that can be fitted to the handrail stopper 1 attached to the attachment C and cover the periphery thereof is fixed to the handrail B. Then, the bracket 4 fixed to the handrail B is moved as shown by an arrow in FIG. 4 to be fitted to the handrail stopper 1 attached to the attachment C, and as shown in FIG. The surroundings of the handrail stopper 1 attached to the attachment C are concealed, and the screw holes 3b and 3a of the handrail stopper 1 and the screws E are sequentially screwed from the screw holes 4c of the bracket, and the handrail stopper 1 and the bracket 4 is fixed with screws E.

  As shown in FIG. 6, when the handrail B is attached to the attachment C that is a wall surface next to the stairs by such construction, the attachment seat 2 of the handrail stopper 1 is attached to the bracket 4 as shown in FIG. 5. Since it fits in the recess 4a and the fixed arm 3 is fitted in the insertion hole 4b of the bracket 4, the handrail stopper 1 attached to the attachment C is covered with the bracket 4 and cannot be seen. . Therefore, the appearance of the handrail after construction is good. Moreover, since the screw E for fixing the handrail stopper 1 and the bracket 4 and the screw F for fixing the bracket 4 and the handrail B are not visible, the appearance of the handrail after construction is better.

  Since the bracket 4 is formed with the horizontally long recess 4a and the insertion hole 4b as described above, at the time of construction, the bracket 4 is attached to the handrail stopper 1 attached to the attachment C which is the wall surface next to the stairs. On the other hand, even if the mounting position of the bracket 4 to which the handrail B is fixed is slightly deviated, the error can be absorbed by the horizontally long recess 4a and the insertion hole 4b. Therefore, the work of attaching the bracket 4 and the handrail B to the handrail stopper 1 can be easily performed.

As described above, the bracket 4 fixed to the handrail B is fitted to the handrail stopper 1 as shown by the arrow in FIG. 4 and the handrail stopper 1 attached to the attachment C is attached. When the surroundings are covered, the tip of the fixed arm 3 of the handrail stopper 1 reaches the insertion hole a formed on the handrail B side as shown in FIG.
By doing in this way, the attachment stability of the comparatively long handrail B can be improved further.

Here, the screw E is screwed upward in the vertical direction from the bracket 4 into the screw holes 3 a and 3 b that are vertically formed in the handrail stopper 1, and the screw E penetrates from the handrail stopper 1. The screw hole 3b on the projecting side is engaged, and the screw hole 3a on the side screwed into the handrail stopper 1 is not engaged.
In this case, it is easy to screw the screw E into the screw hole 3a penetrating in the vertical direction. In addition, there is a variation in processing accuracy of the handrail stopper 1 and the bracket 4 which are constituent members of the handrail bracket A, and the screw hole 3a of the handrail stopper 1 and the screw hole 4a of the bracket 4 may be slightly shifted during mounting. Even if the handrail stopper 1 to be attached to the wall surface or the other attachment object C is soft, it bites into the attachment object C by tightening the screw, and the screw hole 3a of the handrail stopper 1 and the screw of the bracket 4 Even if the hole 4a is somewhat displaced, the screw hole 3a, which is a large hole, absorbs the error, so that the handrail B can be easily attached to the wall surface or other attachments C.

  Here, the handrail bracket A according to the present invention and the handrail mounting structure using the handrail bracket A have been described by way of example only. However, each component and parts used are within the scope of the present invention. Of course, the design can be changed as appropriate. In addition, here, the case where the handrail B is attached to the wall surface next to the stairs has been described as an example. However, the place is not limited in any way, and can be attached to various places as long as it can be attached. .
