Description

  The present invention relates to a mounting bracket used for mounting a head box of a solar shading device such as a horizontal blind, a vertical blind, a raising curtain, a pleated screen, and a roll blind.

  The mounting brackets described in Patent Documents 1 and 2 support a slide block formed of elastic synthetic resin or the like on a bracket body so as to be slidable. Then, with the slide block held in the standby position, one side of the head box is hooked to the bracket body, and in this state, the slide block is pressed by the biasing means by pressing the locking piece of the slide block with the head box. The other side of the head box is locked by sliding to the head box holding position by the urging force. The bracket body is provided with a side wall in which both sides of the upper wall are bent downward and a horizontal support portion in which the tip of the side wall is bent inward, and the lower surface of the slide block is supported by this support portion. Thus, the slide block can be stably slid with respect to the bracket body.

  By the way, when the head box is mounted using the mounting bracket, a gap is left between the top surface of the head box and the ceiling by the difference in height between the top surface of the mounting bracket and the top surface of the head box. In recent years, the demand for high light-shielding properties has increased, and there has been a demand for reducing light leakage from this gap.

  This invention is made | formed in view of such a situation, and provides the attachment bracket which can reduce the light leakage from the upper direction of a head box.

  According to the present invention, the bracket body includes a bracket body, a slide block that is slidably supported with respect to the bracket body, and a biasing member that biases the slide block in a direction away from the bracket body. The head block is provided with a main body latching portion, and the slide block is provided with a slide block latching portion, and the front and rear edges of the headbox can be supported by the main body latching portion and the slide block latching portion. The bracket body includes an upper wall and first and second side walls directed downward from both sides of the upper wall, and the slide block protrudes from both side surfaces. The first and second side walls are engaged with the first and second engaging convex portions to engage the slide block with respect to the bracket body. The bracket body includes first and second slide holes that are slidably supported, and the bracket body includes a protruding portion inward from both the first and second side walls in a region facing the upper surface of the head box. A mounting bracket for a head box is provided that includes a support portion that receives a load applied to the slide block hooking portion in a region that does not face the upper surface of the head box.

  Since a load is applied to the slide block from the head box, it is essential to provide a support for receiving the load. For this reason, in all the conventional techniques, a projecting portion projecting inward from the side wall is provided in a region facing the upper surface of the head box, and the slide block is supported by the projecting portion. In the study of the method for reducing light leakage, the present inventors have found that the presence of this protrusion prevents the difference in height between the upper surface of the mounting bracket and the upper surface of the head box from being reduced. I noticed that I tried to eliminate this protrusion. Since the load from the head box is mainly applied to the slide block latching part, the slide block latching part is firmly supported, and the engagement convex part on the side surface of the slide block is engaged with the slide hole on the side wall of the mounting bracket. If they are combined, it can be seen that the slide block does not fall off from the bracket body even if the support portion is not provided in the region facing the upper surface of the head box, and the present invention has been completed. Conventionally, it has been common sense in the field of the present invention to provide a protruding portion in the area facing the top surface of the head box and receive the load of the slide block, so eliminating this protruding portion is an unusual design. I was worried whether it would work without any problems, but when I tested it on a real machine, it worked without any problems and was able to reduce light leakage from above the headbox.

Hereinafter, various embodiments of the present invention will be exemplified. The following embodiments can be combined with each other.

  Hereinafter, embodiments of the present invention will be described. Various characteristic items shown in the following embodiments can be combined with each other.

1. 1st Embodiment First, the whole structure of the attachment bracket 3 of 1st Embodiment of this invention is demonstrated.
As shown in FIGS. 1 to 9, the mounting bracket 3 to which the head box 1 can be attached includes a bracket body 5, a slide block 7 that is slidably supported with respect to the bracket body 5, and a slide block 7. A coil spring (biasing member) 9 that biases the slide block 7 in a direction away from the bracket body 5 is provided. Usually, the bracket body 5 is formed by bending a metal plate, and the slide block 7 is formed of a synthetic resin having elasticity. In other words, the “direction in which the slide block 7 is separated from the bracket body 5” is a direction in which the front end portion 7l of the slide block 7 is separated from the bracket body 5 (front direction in FIG. 1). This is the direction in which the distance between the stopper 7a and the main body hooks 5ac, 5ad is narrowed.

  The bracket body 5 includes first and second body latching portions 5ac and 5ad, and the slide block 7 includes a slide block latching portion 7a. As shown in FIGS. 6 to 7, the front and rear edges 1 a and 1 b of the head box 1 are supported by the main body engaging portions 5 ac and 5 ad and the slide block engaging portion 7 a, so that the head box 1 is attached to the mounting bracket 3. Fixed. As shown in FIGS. 1 to 2, the front edge 1a of the head box 1 is connected to the main body hooks 5ac, 5ad only on one of the two main body hooks 5ac, 5ad (the first main body hook 5ac). A locking portion 5tc is provided to prevent it from coming off. The head box 1 is supported by the main body latching portions 5ac and 5ad even when the front and rear positions of the plurality of mounting brackets 3 are deviated as compared with the case where the locking portions 5tc are provided at both main body latching portions 5ac and 5ad. It becomes easy to make it easy to work, and the workability is improved and the stability after the head box 1 is attached is improved (described in detail later).

  The bracket body 5 includes an upper wall 5b and side walls 5c and 5d directed downward from both sides of the upper wall 5b. The side walls 5c and 5d are usually formed by bending both sides of the upper wall 5b at a right angle. The main body latching portions 5ac and 5ad are formed by cutting out the side walls 5c and 5d so that the hook-shaped main body latching portions 5ac and 5ad remain. The slide block 7 includes engagement convex portions 7c and 7d protruding from both side surfaces of the main body portion 7b. The side walls 5c and 5d are provided with slide holes 5cs and 5ds that engage with the engaging convex portions 7c and 7d to support the slide block 7 slidably with respect to the bracket body 5. The bracket body 5 also includes a vertical wall 5h used for mounting on a vertical wall surface. The upper wall 5b and the vertical wall 5h are provided with mounting holes 5bh and 5hh, respectively, and screws are inserted into the mounting holes 5bh and 5hh to fix the mounting bracket 3 to a ceiling surface or a wall surface (not shown). .

  As shown in FIGS. 2 and 7, the bracket body 5 is not provided with a protruding portion inward from either of the side walls 5 c and 5 d in the region 1 c facing the upper surface of the head box 1. 1 is provided with a support portion 5e that receives a load applied to the slide block latching portion 7a in a region 1d that does not oppose the upper surface of 1. As shown in FIG. 7, the support portion 5e can support the slide block hooking portion 7a from below in a state where the head box 1 is supported by the main body hooking portions 5ac and 5ad and the slide block hooking portion 7a. Provided in position. The support portion 5e is formed by bending the side walls 5c and 5d inward. Moreover, the support part 5e supports the slide block 7 in back side part 7ce, 7de located in the width direction outer side rather than the slide block latching part 7a. As shown in FIG. 7, when the head box 1 is supported by the main body latching portions 5ac and 5ad and the slide block latching portion 7a, the lower surfaces of the rear side portions 7ce and 7de are the rear edges 1b of the head box 1. And almost the same height.

  The slide block 7 includes a temporary fixing arm 7f having a temporary fixing protrusion 7g protruding outward in the width direction. As shown in FIG. 3, the temporary protrusion 7 g is provided with an upper tapered surface 7 ga that decreases toward the outer side in the width direction. As shown in FIG. 6, the bracket main body 5 is locked with the temporary locking protrusion 7 g in a state where the main body hooking portions 5 ac and 5 ad and the slide block hooking portion 7 a are separated from each other, rather than when the head box 1 is supported. A temporary locking portion 5g is provided. As shown in FIG. 3, the temporary locking portion 5g has a front tapered surface 5gf that guides the temporary locking protrusion 7g to the inside in the width direction on the front side, and a rear notch 5cu on the rear side of the temporary locking portion 5g. A taper surface 5ct facing inward in the width direction is provided on the upper surface of. Furthermore, as shown in FIG. 3, the temporary fixing protrusion 7g has a front locking surface 7gc locked by the temporary locking locking portion 5g on the front side, and a rear tapered surface 7gb inclined inward in the width direction. A lower protrusion 7 gu is provided on the rear side and protrudes downward.

  As shown in FIG. 4, a coil spring accommodating portion 7 i that accommodates the coil spring 9 is provided from the rear side portion 7 de of the slide block 7 toward the front. As shown in FIG. 6D, a groove 7j having a width smaller than the diameter of the coil spring 9 is provided on the bottom surface of the coil spring housing portion 7i. By providing such a groove 7j, it is possible to use the coil spring 9 having a diameter as large as possible while preventing the coil spring 9 from falling. The bracket body 5 includes a coil spring abutting portion 5i that protrudes from the upper wall 5b into the coil spring accommodating portion 7i.

Next, a method for assembling the mounting bracket 3 of this embodiment will be described.
First, as shown in FIGS. 5A to 5B, a bracket body 5, a slide block 7, and a coil spring 9 are prepared, and the coil spring 9 is accommodated in a coil spring accommodating portion 7 i of the slide block 7. .
Next, as shown in FIGS. 5C to 5D, the rear side portions 7ce and 7de of the slide block 7 are inserted between the support portion 5e of the bracket body 5 and the upper wall 5b. At this time, one end of the coil spring 9 is brought into contact with the coil spring contact portion 5i.
As it is, the slide block 7 is pushed in and the engaging projections 7c and 7d are engaged with the slide holes 5cs and 5ds so as to be in the state shown in FIGS. 5E to 5F, and the assembly of the mounting bracket 3 is completed. To do. Since the locking projections 7c and 7d get over the side walls 5c and 5d from the lower side of the bracket body 5 and engage with the slide holes 5cs and 5ds, the force required for this engagement is reduced as shown in FIG. As shown in FIG. 4, tapered surfaces 7ct and 7dt which are lowered toward the outer side in the width direction are formed on the upper surfaces of the engaging convex portions 7c and 7d.

  Further, as shown in FIG. 4, the engaging convex portions 7 c and 7 d are provided on both-end arms 7 ca and 7 da provided on the slide block 7. Since it is provided not on the cantilever arm but on the both-end arms 7ca and 7da, a relatively strong force is required to push the engaging projections 7c and 7d inward in the width direction. 7d cannot be easily removed from the slide holes 5cs, 5ds. For this reason, the engagement convex portions 7 c and 7 d function as a support portion that supports the slide block 7. In the prior art, there are some protrusions provided on the cantilever arm, but such engagement protrusions are pushed inward in the width direction even with a weak force and do not function as a support part. .

Next, a method for attaching the head box 1 to the attachment bracket 3 will be described.
First, before attaching the head box 1, as shown in FIG. 6, the slide block 7 is pushed in the direction of the bracket body 5, and the temporary fixing protrusion 7g is engaged with the temporary fixing latch 5g. Thus, the slide block 7 is temporarily fixed, and the slide block hooking portion 7a is held in a state of being separated from the main body hooking portions 5ac and 5ad. More specifically, when the slide block 7 is pushed in the direction of the bracket body 5, the rear taper surface 7gb shown in FIG. 3 first comes into contact with the front taper surface 5gf of the temporary lock engaging portion 5g, and is temporarily fixed when pushed in as it is. When the arm 7f is elastically deformed, the temporary protrusion 7g is pushed inward in the width direction and enters the inside of the side wall 5c. When the slide block 7 is further pushed in from this state, the temporary protrusion 7g becomes the temporary lock 5g. Get over and go into the rear cutout 5cu. And the front side locking surface 7gc of the temporary fixing protrusion 7g is locked to the temporary locking portion 5g. The slide block 7 is biased in a direction away from the bracket body 5 by the coil spring 9, but the front locking surface 7gc is locked by the temporary locking portion 5g, so that the slide block 7 is moved forward. Movement is prevented. The slide block 7 has a low protrusion 7k on the side opposite to the temporary fixing projection 7g, and the protrusion 7k contacts the side wall 5d of the bracket body 5 so that the width of the slide block 7 with respect to the bracket body 5 is increased. The backlash of the direction is reduced, and the temporary fixing protrusion 7g is prevented from coming off from the temporary fixing latching portion 5g.

  Next, as shown in FIGS. 6 to 7, the rear side 1b of the head box 1 is lifted by lifting the rear side of the head box 1 while the front edge 1a of the head box 1 is supported by the body hooking portions 5ac and 5ad. Is supported by the slide block hooking portion 7a. At this time, the upper surface 1e on the rear side of the head box 1 comes into contact with the lower protrusion 7gu below the temporary protrusion 7g, and pushes the temporary protrusion 7g upward. As shown in FIG. 3, the upper surface of the temporary fixing protrusion 7g is provided with an upper tapered surface 7ga that decreases toward the outer side in the width direction. Therefore, when the temporary fixing protrusion 7g is pushed up, The protruding portion 7g is pushed inward in the width direction and enters the inside of the side wall 5c, whereby the engagement between the front locking surface 7gc and the temporary locking locking portion 5g is released. As a result, the slide block 7 is moved away from the bracket body 5 by the urging force of the coil spring 9, and the distance between the body latching portions 5ac, 5ad and the slide block latching portion 7a is reduced, as shown in FIG. As described above, the head box 1 is held between the main body engaging portions 5ac and 5ad and the slide block engaging portion 7a. Since the upper surface of the rear notch 5cu is provided with a tapered surface 5ct that decreases toward the outer side in the width direction, the upper tapered surface 7ga and the side wall 5c come into contact with each other to reduce wear of the upper tapered surface 7ga. In addition, the temporary fixing protrusion 7g is easily moved inward in the width direction. Furthermore, since the front taper surface 5gf is provided on the rear side of the temporary fixing latching portion 5g, the temporary fixing protrusion 7g is released from the state where it is pushed inward in the width direction, and is shown in FIG. As shown, it is easy to return to the state in the front notch 5cf.

  On the front side of the slide block 7, the lower surfaces of the engaging convex portions 7c and 7d are supported by the slide holes 5cs and 5ds, and on the rear side, the rear side portions 7ce and 7de are supported by the support portion 5e. Most of the load from the head box 1 is applied to the rear side of the slide block 7 through the slide block hooking portion 7a. Therefore, in the region 1c facing the upper surface of the head box 1, the bracket main body 5 is protruded inward to generate another load. The slide block 7 will not come off without providing a support.

Here, the front edge 1a of the head box 1 and the main body latching portions 5ac and 5ad and the state when the head box 1 is attached to the mounting bracket 3 will be described in detail with reference to FIGS.
As shown in FIG. 8A, the tip of the front edge 1a of the head box 1 protrudes downward, and the front edge protruding portion 1at is locked by the locking portion 5tc of the first main body latching portion 5ac. Is done. As a result, the front edge 1a is supported by the main body hooking portions 5ac, 5ad and the rear edge 1b is not supported by the slide block hooking portion 7a. It can be prevented from coming off.

  Of the two main body hooking portions 5ac and 5ad, the first main body hooking portion 5ac is provided with a locking portion 5tc. As shown in FIG. Is not provided with a locking portion 5tc. Therefore, the front edge 1a of the head box 1 is not restrained by the second main body hooking portion 5ad and can move in the direction indicated by the arrow A in FIG.

  As shown in FIG. 9, when the positions of the two mounting brackets 3 in the front-rear direction are shifted by a distance d, the relative position of the front edge 1a with respect to the first main body latching portion 5ac remains the same as in FIG. However, the relative position of the front edge 1a with respect to the second main body latching portion 5ad can be changed as shown in FIG. Therefore, even in the state as shown in FIG. 9, the front edge 1a can be supported by the main body latching portions 5ac and 5ad without any particular problem, and the workability is excellent.

  Further, after the rear edge 1b is supported by the slide block latching portion 7a, as shown in FIG. 8 (d), the front edge 1a is supported by the first main body latching portion 5ac, and FIG. 8 (e). As shown in (f), the front edge protruding portion 1at of the front edge 1a is supported by the second main body latching portion 5ad. Thus, since the front edge 1a of the head box 1 is supported by both the main body latching | locking parts 5ac and 5ad, it is excellent in stability.

  As mentioned above, in this embodiment, since the latching | locking part 5tc is provided only in one of the main body latching | locking parts 5ac and 5ad, it is excellent in workability and stability.

2. Second Embodiment A second embodiment of the present invention will be described with reference to FIG.
In the present embodiment, the longitudinal lengths of the main body latching portions 5ac and 5ad and the front edge 1a are longer than those in the first embodiment. For this reason, as shown in FIG. 10A, the front edge 1a is movable in the front-rear direction by a distance S even when the front edge 1a is supported by the main body latching portions 5ac and 5ad. Conventionally, in a state where the front edge 1a is supported by the main body hanging portions 5ac and 5ad, the range in which the front edge 1a can be moved in the front-rear direction is usually about 0.5 times the plate thickness. In this embodiment, even when the position of the mounting bracket 3 is shifted in the front-rear direction by a distance d as shown in FIG. 9 by setting the movable distance S to be equal to or greater than the plate thickness T of the leading edge 1a. The front edge 1a can be easily supported by the main body hanging portions 5ac and 5ad. The S / T value is preferably larger from the viewpoint of workability, but the larger this value, the larger the mounting bracket 3 protrudes from the head box 1 to the inside of the room, which is detrimental to aesthetics. It is preferably not large, and S / T is preferably 1 to 3, and more preferably 1.5 to 2.5, from the viewpoints of workability and aesthetics.

  In the present embodiment, as shown in FIG. 10, the second main body hooking portion 5ad is also provided with a locking portion 5tc. However, the relative position of the front edge 1a with respect to the second main body hooking portion 5ad is as shown in FIG. Since it can change like (c), even when the position of the attachment bracket 3 has shifted | deviated to the front-back direction, the head box 1 can be attached easily.

  Also in this embodiment, it is preferable that the locking portion 5tc is provided only in the first main body hooking portion 5ac. This is because the workability can be improved without changing the length of the mounting bracket 3 protruding from the head box 1 to the inside of the room.

3. Third Embodiment A third embodiment of the present invention will be described with reference to FIG.
In the first and second embodiments, the load applied to the slide block latching portion 7a is received by the support portion 5e that contacts the rear side portions 7ce, 7de. However, in this embodiment, as shown in FIG. The part 5e is provided so as to contact the lower surface 7h of the slide block latching part 7a. In that case, the support portion 5e can be formed by cutting and bending the vertical wall 5h of the bracket body 5.

4). Fourth Embodiment A fourth embodiment of the present invention will be described with reference to FIGS.
The mounting bracket 3 of the present embodiment is similar to the first embodiment, but the configurations of the temporary fixing arm 7f, the temporary fixing protruding portion 7g, and the temporary fixing locking portion 5g are different. Hereinafter, a description will be given focusing on differences from the first embodiment.
In the present embodiment, as shown in FIG. 14, a temporary fixing projection 7 g is provided so as to protrude outward in the width direction from the temporary fixing arm 7 f. The temporary fixing arm 7f is provided with an inner protruding portion 7ft protruding inward in the width direction, and the inner protruding portion 7ft is in contact with the main body portion 7b, thereby preventing the temporary fixing arm 7f from bending inward in the width direction. Further, the temporary fixing arm 7f is bent upward at the bent portion 7fk. The temporary fixing protrusion 7g is provided on the distal end side of the temporary fixing arm 7f with respect to the bent portion 7fk. A lower protrusion 7 gu that protrudes downward is provided at a position adjacent to the temporary fixing protrusion 7 g.

  As shown in FIG. 13, a front tapered surface 5gf for guiding the temporary fixing projection 7g upward is provided on the front side of the temporary fixing locking portion 5g provided on the bracket body 5, and the temporary fixing protrusion 7g. A rear taper surface 7gb is provided on the side in contact with the front taper surface 5gf. Further, a rear locking surface 5gb is provided on the rear side of the temporary locking portion 5g, and a front locking surface 7gc is provided on the front side of the temporary locking projection 7g.

Next, a method for attaching the head box 1 to the attachment bracket 3 will be described.
First, when the slide block 7 is pushed rearward from the state shown in FIG. 13 (that is, the temporary protrusion 7g is positioned in the front notch 5cf), the rear taper of the temporary protrusion 7g is temporarily pushed. When the surface 7gb comes into contact with the front taber surface 5gf of the temporary locking portion 5g and the slide block 7 is further pushed in the rearward direction, the temporary protruding portion 7g gets over the temporary locking portion 5g, and FIG. ). The slide block 7 is always urged forward by the coil spring 9, and the front locking surface 7gc of the temporary locking projection 7g abuts the rear locking surface 5gb of the temporary locking locking portion 5g. This prevents the slide block 7 from moving in the forward direction. Thereby, the slide block 7 is temporarily fixed. In this state, the temporary protrusion 7g is located in the rear cutout 5cu.

  Next, as shown in FIGS. 15A to 15B, while the front edge 1a of the head box 1 is supported by the main body hooking portions 5ac and 5ad, the rear side of the head box 1 is lifted up, and the head box 1 The rear edge 1b is supported by the slide block hooking portion 7a. At this time, the upper surface 1e on the rear side of the head box 1 comes into contact with the lower protrusion 7gu and pushes the temporary protrusion 7g upward. When the temporary locking projection 7g moves upward and the engagement between the front locking surface 7gc and the rear locking surface 5gb is disengaged, the slide block 7 is moved forward by the biasing force of the coil spring 9, and the main body The distance between the latching portions 5ac, 5ad and the slide block latching portion 7a is reduced, and as shown in FIG. 15B, the head box is located between the body latching portions 5ac, 5ad and the slide block latching portion 7a. 1 is held.

The mounting bracket 3 of the said embodiment can also be implemented with the following aspects.
The vertical wall 5h is not essential and can be omitted.
