Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a handrail support that supports a handrail provided along a wall surface from the wall surface, and more particularly to a handrail attachment adjustment technique.
[0002]
[Prior art]
For attaching handrails to walls such as stairs and corridors, attach handrails and their support in advance and attach the support to the wall with screws, etc. A method of fixing a handrail to the support tool with a screw or the like is then performed. However, many of the wall surfaces lack locality or flatness in a local area or in a wide range, and the wall surfaces at the positions where a plurality of supporters that support the handrail are attached are not oriented in the same direction, and the same plane. Often come in and out.
[0003]
On the other hand, the conventional handrail support is usually an integrally molded product of metal or resin. For this reason, an unreasonable attachment state occurs between at least one of the support tool and the handrail or between the support tool and the wall surface. In that case, the handrail is bent according to the wall accuracy with which it goes in and out, the straightness is hindered, the mounting condition is poor, the mounting strength is insufficient, the mounting is done by forcibly mounting and crushing the screw thread, etc. It takes time for construction.
[0004]
Some conventional handrail supports have a portion corresponding to the elbow that can be rotated and adjusted in one direction. However, with this adjustment, only one direction can be adjusted, and the above problems are hardly solved.
[0005]
[Problems to be solved by the invention]
An object of the present invention is to solve the above-mentioned problems in the prior art, to provide a handrail support that can maintain the linearity of the handrail, can secure the attachment strength, and can be easily installed.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, the present invention provides a handrail support tool for supporting a handrail provided along a wall surface from the wall surface.
A fixing member fixed to the wall surface, a handrail side portion provided with a mounting surface for attaching the handrail on one end side, and a wall side portion facing the fixing member on the other end side with a space therebetween. A supporting member, a fixing member-side contact portion and a supporting member-side contact portion that are interposed between the fixing member and the wall-side portion and have a spherical contact with each other so as to form the gap; The wall-side portion can be attached to the fixing member and the distance can be adjusted at at least three positions apart from the center of the spherical contact-related portion and divided at both sides of a line including the center. And an attachment adjusting means.
[0007]
According to a second aspect of the present invention, in addition to the above, the handrail side portion and the wall side portion are separately provided so that the handrail side portion can move in a direction substantially perpendicular to the wall surface. And a distance adjusting means for allowing the handrail side portion to move in the substantially perpendicular direction.
[0008]
According to a third aspect of the present invention, in addition to the features of the first aspect of the invention, the handrail side portion and the wall side portion are centered on an axis in a direction in which the handrail side portion is substantially perpendicular to the wall surface. It is characterized by being formed as a separate body having a rotatable support relationship.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
1 and 2 show an example of a handrail support to which the present invention is applied.
The handrail support tool supports the handrail 200 provided along the wall surface 100 from the wall surface 100 at a plurality of positions with a certain pitch in the direction. The support substrate 1 as a fixed member, and the handrail side portion of the support member Arm 2 and intermediate ring 3 as the wall side portion, ball 4 as the fixed member side contact portion and contact seat 31 as the support member side contact portion, angle adjusting screw 5 as the attachment adjusting means, front and rear as the distance adjusting means It has adjustment screws 6 and the like.
[0010]
The support substrate 1 has a hole 12 for fixing to the wall surface 100 with a screw 11, a screw hole 13 to be screwed with the angle adjusting screw 5, a center hole 14 into which the ball 4 is fitted, a pin needle 15 for mounting positioning, and the like. Three holes 12 and three screw holes 13 are provided concentrically at almost equal pitches alternately.
[0011]
The arm 2 includes an attachment surface 21 for attaching the handrail 200 on one end side, is bent at an angle close to 90 °, and the root side that is substantially perpendicular to the wall surface rotates and slides on the intermediate ring 3. It is supported freely. In this portion, an operation hole 22 for front-rear adjustment is provided. The attachment surface 21 has an arc-shaped cross section and extends in the length direction of the handrail 200, and has a countersink 24 for attaching the handrail with a screw 23.
[0012]
The intermediate link 3 also serves as a casing, covers the substrate 1 and covers the end of the arm 2, and faces the contact seat 31, the support substrate 1 with a distance d therebetween, and the base of the arm 2. A boss portion 33 that supports the side portion, a countersink 34 provided at a position facing the screw hole 13 of the support substrate 1, a screw hole 35 that is screwed with the front / rear adjustment screw 6, and a set screw 36 that fixes the rotation of the arm 2. , Etc. The base side portion of the arm 2 and the boss portion 33 of the intermediate ring 3 are in a support relationship in which the arm 2 can move in a direction substantially perpendicular to the wall surface 100 and can rotate about an axis 37 in that direction. It is formed as a separate body.
[0013]
The ball 4 and the contact seat 31 are interposed between the support substrate 1 and the intermediate ring 3 and form a spherical contact relationship with each other so as to form the distance d. The ball 4 is fixed in the center hole 14 of the support substrate 1 by swaging, and is prevented from coming off. However, it may be simply fitted or inserted into the center hole 14. Further, the ball 4 may be integrally formed with the support substrate 1.
[0014]
The ball 4 may be provided on the intermediate ring 3 side and the contact seat 31 may be provided on the support substrate 1 side. Furthermore, the contact seat 31 can be formed in a continuous partial spherical shape. That is, in the spherical support relationship, the distance d between the support substrate 1 and the intermediate ring 3 can be maintained at a predetermined position, and the intermediate ring 3 is supported and guided by the support substrate 1 on the spherical surface. It may be formed so that it can rotate smoothly with respect to the wall surface and therefore the surface of the support substrate 1.
[0015]
As shown in FIGS. 2A and 2B, the screw hole 13 of the support substrate 1 into which the angle adjusting screw 5 is screwed and the countersink 34 of the intermediate ring 3 are the center of the ball 4 which is the center of the spherical contact portion. There are three positions separated from both sides of the horizontal line 4b which is one of the lines including the center 4a, which are three positions away from 4a. In this example, these are alternately arranged with the board mounting holes 12 as described above, and they are arranged on a concentric circle at an equal angle of 120 °.
[0016]
If it does in this way, the space | interval d of each position can be changed according to the frequency | count or angle of turning by turning each angle adjustment screw 5. FIG. However, the adjustment allowance may be changed by slightly changing the angle of the position and the radial dimension between the holes. If three angle adjusting screws 5 are provided at the three positions as described above, the intermediate ring 3 can be supported by the support substrate 1 and the inclination of the intermediate ring can be adjusted based on the spherical contact relationship of the ball 4 portion. However, the mounting / adjusting portions may be provided at three or more positions so that the supporting state can be further stabilized, adjustment can be facilitated, and accuracy can be improved.
[0017]
Next, an example of a handrail attachment / adjustment method when the handrail support tool as described above is used will be described.
For example, when the handrail 200 is supported by three support tools, first, the support tools at both ends are attached to predetermined positions on the wall 100. At this time, the center point of the support tool is marked on the wall 100 to be slightly recessed, the pin needle 15 of the support tool is pressed and pierced there, and the support substrate 1 is fixed with the screw 11 at three points. Next, the intermediate ring 3 into which the arm 2 is inserted is put on the support substrate 1, the contact seat 31 is pressed against the ball 4, the angle adjustment screw 5 is appropriately rotated, and the angle adjustment surface 32 is set on the support substrate surface and the wall surface. Set to approximately parallel. At this time, the front / rear adjustment screw 6 is set to an initial setting state, and the set screw 7 is slightly loosened to such an extent that the arm 2 rotates lightly.
[0018]
In this state, the handrail 200 is placed on the attachment surface 21 of the arm 2 of the support tool at both ends. In this state, the handrail 200 is approximately the same distance from the wall surface 100 and is substantially parallel. At this time, if the contact state between the mounting surface 21 and the handrail 200 is not good due to poor flatness of the wall surface 100 at the support position, the angle adjustment screw 5 is turned to change the direction of the intermediate ring 3 to an arbitrary direction. Change direction. At this time, since the contact seat 31 of the intermediate ring 3 is guided by the ball 4 while maintaining spherical contact, the movement of the intermediate ring 3 is performed smoothly and steplessly.
[0019]
According to this adjustment, the arm 2 can rotate these combined arbitrary rotations on the basis of the rotation in the direction parallel to and perpendicular to the paper surface around the center 4a of the ball. Thereby, the space | interval with the wall of the support surface 21, the direction to which a surface faces, the twist of a surface, etc. can be adjusted. Further, along the support surface 21 with respect to the length direction of the handrail, it is automatically adjusted by rotation about the central axis 37 of the arm 2. Therefore, in many cases, the adjustment results in good contact between the mounting surface 21 and the surface of the handrail 200, and the adjustment is completed. In addition, it may replace with the support tool of the both ends of a handrail, and may adjust an end and an intermediate support tool as mentioned above.
[0020]
However, when the angle is adjusted with the angle adjusting screw 5, the distance between the handrail and the wall changes, so that the handrail and the mounting surface are not in good contact with each other, or the adjustment amount is large and the distance from the wall surface is increased. When adjustment is necessary, the front / rear adjustment screw 6 is rotated to adjust the front / rear direction of the arm 2, that is, the distance from the wall 100.
[0021]
When these adjustments are complete, attach the intermediate support. First, a support tool is set at a previously marked position or an appropriate position in an intermediate portion in the length direction of the handrail. At this time, the support substrate 1 is attached to the wall surface 100, and the intermediate ring 3 into which the arm 2 is fitted is put thereon, and the contact state between the support surface 21 and the handrail 200 is observed. This alone usually does not provide a good contact state. At this time, the front / rear adjustment screw 6 and the angle adjustment screw 5 are adjusted in parallel.
[0022]
For example, when the mounting surface is below the handrail and the distance between the two is wide, the angle adjustment screw 5 is turned to adjust the arm 2 so that it rotates clockwise around the center 4a parallel to the paper surface. The adjusting screw 6 adjusts the supporting surface in a direction away from the wall, and adjusts the supporting surface upward by these combined movements so as to follow the handrail. If the support surface is twisted, it is adjusted with the angle adjusting screw 5. In this adjustment, taking into account the deflection of the handrail due to its own weight, the mounting surface is brought into strong contact with the handrail, and the support load of the support surfaces at both ends is shared by this portion. Even when four or more supports are attached to one handrail, the same adjustment can be made.
[0023]
When the adjustment of all the supports is completed, the set screw 36 is tightened, and the handrail 200 is attached and fixed to the attachment surface 21 with the screw 22 in a state where the support is fixed. In this case, since the handrail can be fixed in a state where all the mounting surfaces are in uniform contact with the handrail and the load is almost uniformly distributed, the straightness of the handrail in the vertical direction can be maintained. Further, since the mounting surface and the handrail are coupled in a good contact state, an excessive bending force or the like does not act on the handrail, and linearity in all directions of the handrail is maintained. And by attaching all the support tools to the handrail and the wall surface without difficulty, the attachment state of the handrail is improved, the attachment strength is secured, and the handrail can be supported safely and reliably. Furthermore, since the screw is not forcibly tightened, the mounting work is facilitated and the working time is shortened.
[0024]
In the above description, the arm and the intermediate ring are separated from each other, and the space between them is slidable and rotatable. In this way, complete adjustment can be easily performed as described above. However, in order to simplify the structure of the support, reduce costs, etc., it is also possible to make a structure in which only one of rotation and sliding can be adjusted between the arm 2 and the center ring 3. Furthermore, you may form both integrally.
[0025]
For example, when the arm 2 and the ring 3 are integrally formed, all adjustments are made only by the angle adjusting screw 5. At this time, for example, when the screw 11 can be tightened from the outside of the intermediate ring 3 portion and the support substrate is screwed to the wall surface, the consistency of the handrail length direction between the handrail and the mounting surface is adjusted. In this adjustment, the support substrate 1 is rotated little by little around the pin needle 15 so that the arm mounting surface faces the length direction of the handrail. Such adjustment is the same as that of a conventional support.
[0026]
In this state, the handrails are placed on the support members at both ends, and the support tools at both ends are placed so that the handrails are at the same distance from the wall surface and the support surface 21 and the handrail 200 are along with the angle adjusting screw 5. Make fine adjustments. In the intermediate support, the adjustment of the center position of the support substrate, the rotation adjustment around the center, and the adjustment by the angle adjustment screw 5 are performed in parallel to stabilize the contact state between the support surface 21 and the handrail. Therefore, according to such a support tool, the adjustment work is somewhat troublesome, and the adjustment accuracy is somewhat lowered. However, even when the flatness of the wall surface is poor, a considerable contact adjustment can be performed, and there is no problem that the handrail is forcibly fixed and the mounting state is deteriorated as in the conventional case.
[0027]
【The invention's effect】
As described above, according to the present invention, in the first aspect of the present invention, the fixing member is fixed to the wall surface, the support member is opposed to the wall member with a space therebetween, and a contact portion forming a spherical contact relationship therebetween. And the mounting adjustment means can be mounted and the distance between them can be adjusted, so that the support member is inclined in any direction with respect to the wall surface by the spherical contact portion and the mounting adjustment means via the fixing member. It is supported from the wall surface as possible. As a result, by operating the distance adjusting means, the position and direction of the handrail attachment surface of the support member can be adjusted, and the handrail can be attached to the support in a state where the handrail and the attachment surface are in good contact. .
[0028]
When supporting a handrail using a plurality of such support tools, if all of them are adjusted to make each contact state good, all the mounting surfaces are in uniform contact with the handrail. Since the handrail can be fixed in a state where the load is shared, and an excessive bending force is not applied, the linearity of the handrail can be secured. In addition, the handrail is attached in an improved state, and attachment strength is also obtained. Furthermore, since there is no excessive fixing work, the mounting work becomes easy and the working time is shortened.
[0029]
In the invention of claim 2, in addition to the above, the handrail side portion and the wall side portion of the support member are separated, and these are supported so that the handrail side portion can move in a direction substantially perpendicular to the wall surface. In addition to providing the relationship, the distance adjusting means that enables the movement is provided, so that the distance from the handrail wall can be easily adjusted. As a result, this adjustment and the adjustment of the inclination of the support member can be combined to make an easier and more accurate adjustment.
[0030]
In the invention of claim 3, in addition to the invention of claim 1, the supporting member is separated into a handrail side portion and a wall side portion, and these are directions in which the handrail side portion is substantially perpendicular to the wall surface. Therefore, the attachment portion is rotatable in a direction parallel to the wall surface, and the attachment portion is automatically adjusted following the surface of the handrail in the length direction of the handrail. Therefore, the adjustment becomes easier and the accuracy can be improved. If the rotatable structure and the distance adjusting means are combined, the simplest and complete adjustment can be performed.
