Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in this type of mounting bracket for blinds, since a part of the slide block is exposed to the indoor side, it is preferable to make the slide block the same color system as the head box from the viewpoint of design. However, since it is not preferable in terms of parts management to prepare a large number of slide blocks according to the number of colors of the head box, it is common to use a slide block formed of a transparent resin.

[0006] However, when the slide block is formed of a transparent resin, there is a problem that the selection range of materials for improving the strength and durability of the locking portion of the slide block to which a load is applied becomes narrow.

[0007] The present invention has been made in view of the above problems, and an object thereof is to provide a mounting bracket for a blind that can widen the selection range of materials for improving the strength and durability of the locking portion of the slide block.

Means for Solving the Problems

[0008] To achieve the above object, a mounting bracket for a blind according to one embodiment of the present invention includes a bracket body fixed to a fixing surface, a slide block slidably held by the bracket body, and biasing means for biasing the slide block to one side in the sliding direction. The bracket body has a first locking portion at one end in the sliding direction, the slide block has a second locking portion at the other end in the sliding direction, and the mounting bracket for a blind can support both ends in the short side direction of the blind support member by the first locking portion, the second locking portion, and the biasing force of the biasing means. The slide block has a first component member slidably held by the bracket body, and a second component member having the second locking portion and provided slidably in a state of being placed and engaged with the upper surface of the first component member and integrally formed.

[0009] According to this configuration, since the first component member held by the bracket body and the second component member having the second locking portion can be separate parts, it is possible to widen the selection range of materials for improving the strength and durability of the locking portion of the slide block. For example, by forming the first component member from a resin-based material as before and the second component member from a metal-based material, it is also possible to improve the strength and durability of the locking portion of the slide block. In addition, since the holding structure of the slide block can easily utilize the specifications of the existing bracket body, it is possible to suppress the cost associated with design changes.

[0010] The first component member may have an operation portion that can be operated in a direction against the biasing force of the biasing means.

[0011] In this case, the second component member may have a first engaging portion that engages with a part of the first component member, and a second engaging portion that is formed on a part of the second locking portion and engages with the other end of the first component member in the sliding direction.

[0012] According to these configurations, since the operation portion and the second locking portion can be formed as separate components, for example, the first component member having the operation portion exposed on the indoor side is formed of a transparent resin-based material, and the second component member having the second locking portion is formed of a metal-based material, so that the strength and durability of the second locking portion can be improved without causing a decrease in the design property of the portion exposed on the indoor side. Further, the second component member can be easily and surely assembled to the first component member.

[0013] The second component member may have an operation portion that can be operated in a direction against the biasing force of the biasing means.

[0014] In this case, the second component member may have a first engaging portion that is formed on a part of the operation portion and engages with one end of the first component member in the sliding direction, and a second engaging portion that is formed on a part of the second locking portion and engages with the other end of the first component member in the sliding direction.

[0015] According to these configurations, the operation portion and the second locking portion can be formed as the same component. Further, the second component member can be easily and surely assembled to the first component member.

[0016] The bracket body has a holding portion that slidably holds the slide block. The second component member may be formed in a shape such that at least a part thereof overlaps with the holding portion with respect to the vertical direction of the bracket body.

[0017] According to this configuration, even if the first component member is damaged by any chance, the second component member is held by the holding portion, so that the second component member can be prevented from falling.

[0018] The second component may be formed of a material having a higher strength than that of the first component.

[0019] According to this configuration, it becomes possible to appropriately select a material capable of improving the strength and durability of the locking portion. For example, a resin material can be selected for the first component, and a metal material can be selected for the second component. Also, a resin material can be selected for the first component, and a resin material having a higher strength than the first component can be selected for the second component.

[0020] The second component may be formed from a press-formed product obtained by bending and shearing a thin plate material.

[0021] According to this configuration, a metal material can be selected as the second component having the second locking portion.

[0022] The bracket body may have an insertion hole through which a screw for fixing the bracket body to the fixing surface can be inserted. In this case, the first component may have a first opening capable of exposing the insertion hole, and the second component may have a second opening capable of exposing the insertion hole corresponding to the first opening.

[0023] According to this configuration, it is possible to easily access the insertion hole for screw fixation while configuring the slide block with two members.

Advantages of the Invention

[0024] As described above, according to the present invention, it is possible to provide a mounting bracket for a blind that can widen the selection range of materials for improving the strength and durability of the locking portion of the slide block. However, the effects are not intended to limit the present invention.

Embodiments for Carrying Out the Invention

[0026] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0027] <First Embodiment> First, the first embodiment of the present invention will be described.

[0028] [Configuration of Mounting Bracket for Blind] FIG. 1 is a side view of the mounting state of the mounting bracket for a blind according to the present embodiment. FIGS. 2 and 3 are bottom-side perspective views and exploded perspective views of the mounting bracket for a blind. FIGS. 4 and 5 are perspective views and exploded perspective views of the slide block of the mounting bracket for a blind. FIG. 6 is a bottom-side perspective view of the second constituent member of the slide block. FIG. 7 is a side view of the slide block, showing a state in which the first constituent member and the second constituent member are separated (FIG. 7(a)), a procedure for integrating the first constituent member and the second constituent member (FIG. 7(b)), and a state in which the first constituent member and the second constituent member are integrated (FIG. 7(c)). FIGS. 8 and 9 are plan views and bottom views of the slide block, and FIGS. 10 and 11 are cross-sectional views taken along line A-A and line B-B of FIG. 8.

[0029] As shown in FIG. 1, the mounting bracket 100 for a blind (hereinafter simply referred to as the bracket 100) is a mounting member for fixing the support member S of the blind to a fixing surface such as the ceiling surface C of a window frame inside a building.

[0030] The support member S is, for example, a set frame of a roll screen or a head box of a Venetian blind, a pleated screen, or a honeycomb screen, and supports a shielding material (screen or slats; not shown) of the blind. The support member S has a horizontally long flat plate shape or a horizontally long rectangular parallelepiped shape, and its upper surface is fixed to the ceiling surface C or the like via the bracket 100 with screws N or the like.

[0031] The bracket 100 has a bracket body 1 fixed to the ceiling surface C and a slide block 2 slidably held by the bracket body 1.

[0032] As shown in FIG. 1, when the bracket 100 is attached to the ceiling surface C, the slide block 2 is slidably attached in the front (indoor side) - rear (outdoor side) direction (Z direction in the figure) of the blind.

[0033] The bracket body 1 has a first locking portion 11 at the indoor - side end, and the slide block 2 has a second locking portion 22 at the outdoor - side end. Further, between the bracket body 1 and the slide block 2 on the outdoor side of the bracket 100, biasing means 3 (see FIGS. 4 and 12) for biasing the slide block 2 in the indoor - side direction is provided. Thereby, the bracket 100 can support both ends of the blind support member S in the short - hand direction (Z direction) by the first locking portion 11, the second locking portion 22, and the biasing force of the biasing means 3.

[0034] The bracket body 1 is formed of, for example, a metal press member. As shown in FIGS. 2 and 3, the bracket body 1 has a plurality (for example, three) of mounting holes 14 on its top surface for inserting screws N for attaching the bracket 100 to the ceiling surface C.

[0035] Also, as shown in FIGS. 1 to 3, the bracket body 1 has an opening 13 on its side surface, and as shown in FIGS. 2 and 3, it has a holding portion 15 bent in an L - shaped cross - section from the vicinity of the opening 13 on the side surface to the bottom surface side.

[0036] As shown in FIGS. 4 to 11, the slide block 2 according to the present embodiment is composed of a first constituent member 2a and a second constituent member 2b, and both are integrally slidable.

[0037] As shown in FIGS. 5 and 7, the first component member 2a has a concave portion 25 on its upper surface. The second component member 2b is placed and engaged in the concave portion 25 so that the upper surfaces of the first component member 2a and the second component member 2b are substantially flush, and they are integrally formed. That is, most of the first component member 2a and the second component member 2b overlap in the vertical direction (Y direction).

[0038] The second component member 2b has an operation portion 21 at its indoor-side end that can be pressed in a direction (Z direction: sliding direction) against the biasing force of the biasing means 3. Further, the second component member 2b is located on the outdoor side in the state of being attached to the ceiling surface C, and has the second locking portion 22 at its outdoor-side end.

[0039] The second component member 2b is formed of a material having higher strength than the first component member 2a. Specifically, the first component member 2a can be formed by injection molding using a resin-based material such as polycarbonate or polyacetal. The first component member 2a may be translucent or transparent. On the other hand, the second component member 2b can be formed from a press-formed product obtained by bending and shearing a thin metal plate material such as stainless steel or SPCC (cold-rolled steel sheet). The second component member 2b may also be formed of a glass fiber-reinforced resin or the like.

[0040] To integrate the first component member 2a and the second component member 2b, as shown in FIG. 7(b), with the outdoor-side end of the first component member 2a locked in the gap between the second locking portion 22 and the upper surface at the outdoor-side end of the second component member 2b, the indoor-side end of the second component member 2b is rotated and fitted into the concave portion 25 of the first component member 2a.

[0041] Then, as shown in FIG. 7(c), the first engaging portion 26 located at the bent end of the operation portion 21 at the indoor-side end of the second component member 2b engages with the indoor-side end of the first component member 2a, and the second engaging portion 27 located on the upper surface of the second locking portion 22 at the outdoor-side end of the second component member 2b engages with the outdoor-side end of the first component member 2a, so that the upper surfaces of both are substantially flush and integrated.

[0042] As shown in FIGS. 3, 4, and 12, the biasing means 3 includes a biasing member 31 such as a coil spring, a recess 32 formed at the outdoor-side end of the first component 2a of the slide block 2, and a protrusion 33 formed on the inner surface of the outdoor-side end of the bracket body 1. One end side of the biasing member 31 is accommodated in the recess 32, and the other end side is engaged with the protrusion 33.

[0043] Also, as shown in FIGS. 2 to 5, 7 to 9, the second component 2b has a claw portion 23 on its side surface. The slide block 2 is slidably inserted into the bracket body 1 from the side of the first locking portion 11 with the first component 2a and the second component 2b integrated, the claw portion 23 is engaged with the opening 13 of the bracket body 1, and its bottom surface is held by the holding portion 15 of the bracket body 1.

[0044] Thereby, the slide block 2 is slidable relative to the bracket body 1 against the biasing force of the biasing means 3 within the range where the claw portion 23 moves within the opening 13 by the pressing operation of the operation portion 21 from the indoor side to the outdoor side in the Z direction.

[0045] That is, when there is no pressing operation, the operation portion 21 and the indoor-side end of the bracket body 1 are substantially flush, and when there is a pressing operation, the operation portion 21 is buried within the bracket body 1.

[0046] Also, as described above, a plurality of mounting holes 14 for inserting screws N for attaching the bracket 100 to the ceiling surface C are provided on the top surface of the bracket body 1. As shown in FIGS. 2 to 6, 8, and 9, the first component 2a has, for example, a long-hole-shaped first opening 24a that can expose the mounting holes 14, and the second component 2b has a second opening 24b that can expose the mounting holes 14 at a position and shape corresponding to the first opening 24a. The shapes and sizes of the first opening 24a and the second opening 24b are appropriately changed according to the number and size of the mounting holes 14.

[0047] As a result, even though the slide block 2 is composed of two members, it is possible to easily access the mounting hole 14 for fixing the screw N through the first opening 24a and the second opening 24b.

[0048] [Operation when attaching the support member] Next, the operation when attaching the support member S to the bracket 100 configured as described above will be described.

[0049] FIG. 12 is a cross-sectional view in the side direction showing the procedure for attaching the support member S to the bracket 100.

[0050] When attaching the support member S to the bracket 100, first, with the indoor-side end of the support member S locked to the first locking portion 11 of the bracket main body 1 from the state shown in FIG. (a), as shown in FIG. (b), with the first locking portion 11 as a fulcrum, the outdoor-side end of the support member S is rotated in the direction of the arrow in the figure (counterclockwise direction).

[0051] Then, when the outdoor-side end of the support member S abuts against the second locking portion 22 of the second component 2b due to the above rotation, the support member S is further rotated in the state of the abutment. Then, the slide block 2 is pressed in the direction of the arrow in the figure (Z direction) against the biasing force of the biasing member 31.

[0052] When the support member S is further rotated, the slide block 2 is further pressed, and as shown in FIG. (c), the outdoor-side end of the support member S rides up on the second locking portion 22, and finally, as shown in FIG. (d), when the outdoor-side end of the support member S completely rides up on the second locking portion 22, the slide block 2 returns to the original position on the left side of the figure by the biasing force of the biasing member 31, and the outdoor-side end of the support member S is locked to the second locking portion 22, and the attachment is completed.

[0053] When removing the support member S from the bracket 100, when the operation unit 21 is pressed in the Z direction, the slide block 2 slides against the biasing force of the biasing member 31 in the same manner as described above, and the end portion of the support member S on the outdoor side moves away from the second locking portion 22 and becomes completely disengaged from the second locking portion 22 (the arrow points in the opposite direction in Fig. (b)). As a result, the slide block 2 returns to its original position on the left side of the figure due to the biasing force of the biasing member 31, and by rotating the end portion of the support member S on the outdoor side in the clockwise direction with the end portion on the indoor side as a fulcrum, the support member S can be removed from the first locking portion 11.

[0054] As described above, according to the present embodiment, since the first component member 2a held by the bracket main body 1 and the second component member 2b having the second locking portion 22 can be separate components, the range of material selection for improving the strength and durability (including chemical resistance such as to alcohol) of the locking portion of the slide block 2 can be widened. Specifically, by forming the first component member 2a from a resin-based material as in the prior art and forming the second component member 2b from a metal-based material, the strength and durability of the second locking portion 22 of the slide block 2 can also be improved. In addition, regarding the holding structure of the slide block 2, the specifications of the existing bracket main body 1 can be easily diverted, so that the cost associated with design changes can be suppressed.

[0055] [Modification Example] Figs. 13 to 16 are an exploded perspective view, a perspective view, a bottom view, and a plan view of a slide block according to a modification of the first embodiment. Fig. 17 is a cross-sectional view taken along line C-C of Fig. 16.

[0056] As described above, the bracket main body 1 has a holding portion 15 that slidably holds the slide block 2. In this modification, as shown in Figs. 13 to 17, the second component member 2b of the slide block 2 has support pieces 28 at both ends in the short side direction (X direction) that at least partially overlap the holding portion 15 with respect to the vertical direction (Y direction) of the bracket main body 1 (see Figs. 16 and 17).

[0057] The support piece 28 is provided so as to protrude in the X direction on the side of the second locking portion 22 of the second component 2b corresponding to the position of the holding portion 15, and the concave portion 25 of the first component 2a is also formed in a shape that matches the shape of the two support pieces 28.

[0058] According to this modification, for example, even if the resin-made first component 2a is accidentally damaged due to external force, hydrolysis, etc., since the support piece 28 of the second component 2b is held by the holding portion 15, it is possible to prevent the second component 2b from falling together with the blind.

[0059] <Second Embodiment> Next, a second embodiment of the present invention will be described. In this embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description will be omitted or simplified.

[0060] FIGS. 18, 19, and 20 are an exploded perspective view, a perspective view, and a plan view of the slide block according to this embodiment. FIG. 21 is a cross-sectional view taken along line D-D of FIG. 20.

[0061] In the above-described first embodiment, the second component 2b of the slide block 2 had the operation portion 21. In contrast, in this embodiment, as shown in each figure, the first component 2a has the operation portion 21 at its indoor-side end.

[0062] The second component 2b has a hook-shaped first engaging portion 29a bent downward at its indoor-side end, and the indoor-side end of the concave portion 25 of the first component 2a has a groove portion 29b that can engage with the first engaging portion 29a. The point that the second component 2b has the second locking portion 22 and the engagement mode between the first component 2a and the second component 2b at the outdoor-side end are the same as those in the above-described Embodiment 1.

[0063] The second component 2b is integrated with the first component 2a by fitting into the concave portion 25 in a state where the first engaging portion 29a is engaged with the groove portion 29b.

[0064] Thus, according to this embodiment, since the operation unit 21 and the second locking unit 22 can be formed as separate components, for example, the first component member 2a having the operation unit 21 exposed on the indoor side is formed of a transparent resin-based material, and the second component member 2b having the second locking unit 22 is formed of a metal-based material, so that the strength and durability of the second locking unit 22 can be improved without causing a decrease in the design property of the portion exposed on the indoor side. Also, with a simple configuration in which the first engaging portion 29a engages with the groove portion 29b, the second component member 2b can be easily and surely assembled to the first component member 2a.

[0065] <Modification Example> The present invention is not limited only to the above-described embodiment, and various modifications can be made without departing from the gist of the present technology.

[0066] In the above-described first embodiment, the first component member 2a and the second component member 2b of the slide block 2 are engaged with each other at the first engaging portion 26 and the second engaging portion 27, but such engagement is not essential, and they may be engaged at any one location, or may not be engaged at all, and the second component member 2b may only be placed and engaged (fitted) in the concave portion 25 of the first component member 2a.

[0067] The configuration modes of the first component member 2a and the second component member 2b of the slide block 2 are not limited to those shown in the above-described embodiments, and any configuration can be realized as long as the second component member 2b is placed and engaged with the first component member 2a. For example, in the first embodiment and the second embodiment, a predetermined portion may be replaced with the second component member 2b from the outdoor-side end portion of the first component member 2a. Also, the support piece 28 of the second component member 2b shown in the modification example of the first embodiment may be extended to the outdoor-side end portion. In this way, for example, by increasing the ratio of the second component member 2b formed of a metal material, the strength and durability of the slide block 2 can be further enhanced.
