Description

[Technical field]

[0001] The present invention relates to a mounting bracket for blinds. [Background technology]

[0002] A conventional mounting bracket for blinds is known from Patent Document 1 below.

[0003] The mounting bracket for blinds shown in the same document comprises a bracket body, a slide block slidably supported on the bracket body, and a biasing means for biasing the slide block, and is configured to support a head box (support member) of the blind by means of locking portions provided on each of the bracket body and the slide block. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3150555 Summary of the Invention [Problem to be solved by the invention]

[0005] In this type of blind mounting bracket, a part of the slide block is exposed to the interior of the room, so from a design standpoint it is preferable that the slide block be the same color as the head box. However, since preparing a large number of slide blocks according to the number of colors of the head box is not preferable in terms of parts management, it is common to use slide blocks made of transparent resin.

[0006] However, forming the slide block from a transparent resin has the problem that the range of materials that can be used for the slide block is narrowed.

[0007] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a mounting bracket for blinds that allows for a wider range of materials to be selected for the slide block without compromising the design of the part exposed to the inside of the room. [Means for solving the problem]

[0008] In order to achieve the above object, a blind mounting bracket according to one embodiment of the present invention comprises a bracket body fixed to a fixed surface, a slide block slidably held on the bracket body, and a 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, and the slide block has a second locking portion at the other end in the sliding direction, and the blind mounting bracket can support both ends of a blind support member in the short side direction by the first locking portion, the second locking portion, and the biasing force of the biasing means. The slide block comprises a first component member having the second locking portion, and a second component member slidably provided integrally with the first component member and having an operating portion operable in a direction against the biasing force of the biasing means.

[0009] The first component and the second component may be made of different materials.

[0010] The first component may be formed of a material having a higher strength than the second component.

[0011] These configurations allow the material of the first component having the second locking portion to be appropriately selected regardless of the material of the second component, thereby expanding the range of materials that can be used for the slide block, and thus allowing the strength of the blind mounting bracket to be improved by selecting a strong material for the first component.

[0012] The second component member may be formed from a transparent resin material.

[0013] As a result, even if the blind is attached to the ceiling and a part of the second component is exposed to the inside of the room, the above-mentioned effect can be obtained while maintaining the same design as before.

[0014] The first component and the second component may each have an engaging portion that is engageable with each other.

[0015] This allows the first component member and the second component member to slide together in an engaged state.

[0016] The bracket body may have a retaining portion that slidably holds the first component and the second component, and the first component and the second component may each have the engagement portion at a position where they are held by the retaining portion.

[0017] This makes it possible to prevent the first and second components attached to the bracket body in an integrally engaged state from being separated during the sliding movement.

[0018] The engaging portion may be engageable in a direction perpendicular to the sliding direction and perpendicular to a longitudinal direction of the blind support member.

[0019] This allows the first and second components to be attached to the bracket body in a state where they are integrally engaged with each other, even if the bracket body does not have a retaining portion. Effect of the Invention

[0020] As described above, according to the present invention, it is possible to expand the range of materials that can be used for the slide block without compromising the design of the portion exposed to the interior of the room. However, this effect does not limit the present invention. [Brief description of the drawings]

[0022] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0023] [Configuration of blind mounting bracket] Fig. 1 is a side view of a mounted state of a blind mounting bracket according to one embodiment of the present invention. Fig. 2 is a bottom perspective view (Fig. 2(a)) and a top perspective view (Fig. 2(b)) of the blind mounting bracket. Fig. 3 is an exploded perspective view of the blind mounting bracket, and Fig. 4 is an exploded perspective view of a slide block of the blind mounting bracket. Fig. 5 is a top cross-sectional view of the blind mounting bracket, and Fig. 6 is a cross-sectional view taken along line AA in Fig. 5.

[0024] As shown in FIG. 1, a blind mounting bracket 100 (hereinafter simply referred to as bracket 100) is a mounting member for fixing a blind support member S to a fixed surface such as a ceiling surface C of a window frame inside a building.

[0025] The support member S is, for example, a set frame for a roller blind or a head box for a Venetian blind, pleated screen, or honeycomb screen, and supports the blind's shielding material (screen or slat; not shown). The support member S has a horizontally elongated flat plate shape or a horizontally elongated rectangular parallelepiped shape, and its upper surface is fixed to the ceiling surface C or the like by screws or the like via the bracket 100.

[0026] The bracket 100 has a bracket body 1 fixed to a ceiling surface C, and a slide block 2 held on the bracket body 1 so as to be slidable.

[0027] As shown in FIG. 1, when the bracket 100 is attached to a ceiling surface C, the slide block 2 is attached so as to be slidable in the front (inside) to rear (outside) direction of the blind (Z direction in the figure).

[0028] The bracket body 1 has a first locking portion 11 at the end on the indoor side, and the slide block 2 has a second locking portion 23 at the end on the outdoor side. Furthermore, between the bracket body 1 and the slide block 2 on the outdoor side of the bracket 100, a biasing means 3 (see FIG. 5) is provided that biases the slide block 2 toward the indoor side. This enables the bracket 100 to support both ends of the blind support member S in the short side direction (Z direction) by the biasing forces of the first locking portion 11, the second locking portion 23, and the biasing means 3.

[0029] The bracket body 1 is formed of, for example, a pressed metal member. As shown in Figures 2 and 3, the bracket body 1 has a plurality of (for example, three) mounting holes 14 on its top surface through which screws for mounting the bracket 100 to a ceiling surface C are inserted.

[0030] As shown in Figures 1 to 5, the bracket main body 1 has an opening 13 on its side, and as shown in Figures 2, 5 and 6, has a retaining portion 12 bent into an L-shaped cross section from the vicinity of the opening 13 on the side toward the bottom surface.

[0031] As shown in Figures 2 to 6, unlike conventional slide blocks which are composed of a single member, the slide block 2 of this embodiment is composed of a first component member 21 and a second component member 22, and the two can slide together.

[0032] The first component member 21 is located on the exterior side when attached to the ceiling surface C, and has the second engaging portion 23 at its exterior end.

[0033] The second component member 22 is located on the indoor side when attached to the ceiling surface C, and has an operating portion 24 at its indoor end portion which can be pressed in a direction against the biasing force of the biasing means 3.

[0034] 3 to 6, the first component member 21 has a hook-shaped first engagement portion 26 at its end on the indoor side, and the second component member 22 has a hook-shaped second engagement portion 27 at its end on the outdoor side that matches the engagement of the first engagement portion 26. The first engagement portion 26 and the second engagement portion 27 engage with each other in the up-down direction (Y direction; a direction perpendicular to the sliding direction and perpendicular to the longitudinal direction of the support member S), whereby the first component member 21 and the second component member 22 are integrally configured.

[0035] The first component member 21 and the second component member 22 are made of different materials. For example, the first component member 21 can be made of a material stronger than the second component member 22. In this case, the first component member 21 can be made of, for example, metal or glass fiber reinforced resin, and the second component member 22 can be made of, for example, a resin-based transparent, semi-transparent, or white material such as polycarbonate or polyacetal.

[0036] This allows the same design as before to be maintained even when the blinds are attached to the ceiling and part of the second component 22 (operating unit 24) is exposed to the inside of the room, while also expanding the range of materials that can be selected for the slide block 2.

[0037] 3 and 5, the biasing means 3 has a biasing member 31 such as a coil spring, a recess 32 formed on the exterior end of the first component member 21 of the slide block 2, and a protrusion 33 formed on the inner surface of the exterior end of the bracket body 1. One end of the biasing member 31 is housed in the recess 32, and the other end engages with the protrusion 33.

[0038] In addition, the second component member 22 of the slide block 2 has a claw portion 25 on its side. The slide block 2 is slidably inserted into the bracket body 1 from the first locking portion 11 side with the first component member 21 and the second component member 22 engaged and integrated, and the claw portion 25 engages with the opening portion 13 of the bracket body 1, and its bottom surface is held by the holding portion 12 of the bracket body 1. As a result, the slide block 2 is able to slide against the biasing force of the biasing means 3 relative to the bracket body 1 within the range in which the claw portion 25 moves within the opening portion 13.

[0039] Furthermore, the first engaging portion 26 of the first component member 21 and the second engaging portion 27 of the second component member 22 are provided at positions where they are both held by the holding portion 12 of the bracket main body 1. This allows the slide block 2 to be easily attached by simply sliding the slide block 2 into the bracket main body 1 so that the first engaging portion 26 and the second engaging portion 27 are positioned in the holding portion 12 with the first component member 21 and the second component member 22 engaged with each other.

[0040] [Operation when installing / removing support members] Next, the operation of the bracket 100 configured as above when attaching and detaching the support member S will be described.

[0041] 7A to 7C are side cross-sectional views showing a procedure for attaching the support member S to the bracket 100. FIG.

[0042] When attaching the support member S to the bracket 100, first, as shown in Figure 1(a), the indoor side end of the support member S is engaged with the first locking portion 11 of the bracket main body 1, and then, as shown in Figure 1(b), the outdoor side end of the support member S is rotated in the direction of the arrow in the figure (counterclockwise) with the first locking portion 11 as a fulcrum.

[0043] When the outer end of the support member S comes into contact with the second locking portion 23 of the first component member 21 due to the rotation, the support member S is further rotated in this contact state. 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.

[0044] When the support member S is further rotated, the slide block 2 is further pressed, and as shown in Figure 1(c), the outdoor end of the support member S rides up onto the second locking portion 23. Finally, as shown in Figure 1(d), when the outdoor end of the support member S rides completely up onto the second locking portion 23, the force of the biasing member 31 causes the slide block 2 to return to its original position on the left side of the figure, and the outdoor end of the support member is locked by the second locking portion 23, completing the installation.

[0045] FIG. 8 is a side cross-sectional view showing a procedure for removing the support member S from the bracket 100.

[0046] When removing the support member S from the bracket 100, first, from the attached state shown in Fig. 1(a), the operating portion 24 of the slide block 2 is pressed in the direction of the arrow (Z direction) as shown in Fig. 1(b). Then, the slide block 2 slides in the direction of the arrow against the biasing force of the biasing member 31, and the outside end of the support member S gradually moves away from the second locking portion 23.

[0047] When the operating portion 24 is pressed further, as shown in Fig. 1(c), the outdoor end of the support member S is completely disengaged from the second locking portion 23. From this state, the outdoor end of the support member S is rotated in the direction of the arrow in Fig. 1 (clockwise direction) with the indoor end as a fulcrum.

[0048] Then, as shown in FIG. 1(d), the force of the biasing member 31 causes the slide block 2 to return to its original position on the left side of the figure, and the indoor end of the support member S is removed from the first engagement portion 11, completing the work.

[0049] In this way, the first component member 21 and the second component member 22 of the slide block 2 do not separate during the installation and removal operation of the support member S, so that even if the slide block 2 is composed of two components, the installation and removal of the support member S can be easily performed in the same manner as in the conventional method.

[0050] As described above, according to this embodiment, the material of the first component member 21 of the slide block 2 can be appropriately selected regardless of the material of the second component member 22, so that the second component member 22 exposed to the interior side can be made of a material that does not impair the design, such as a transparent material, while widening the range of material choices for the slide block 2. In addition, by selecting a strong material for the first component member 21, the strength of the bracket 100 can be improved.

[0051] [Variations] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and scope of the present technology.

[0052] Fig. 9 is an exploded perspective view of a bracket 100 according to a first modified example of the present invention. Fig. 10 is a plan sectional side view of the bracket 100 of Fig. 9, and Fig. 11 is a BB sectional view of Fig. 10.

[0053] In the above embodiment, the first engaging portion 26 of the first component member 21 and the second engaging portion 27 of the second component member 22 are hook-shaped and engageable in the up-down direction (Y direction). In contrast, in this modified example, the first engaging portion 26 and the second engaging portion 27 are L-shaped in cross section instead of hook-shaped, and are not engaged in the sliding direction (Z direction: short side direction of the support member S) but are engageable in the left-right direction (X direction: longitudinal direction of the support member S). Therefore, the first component member 1 and the second component member 22 are not integrated in the sliding direction (Z direction: short side direction of the support member S) when not attached to the bracket main body 1.

[0054] With this configuration, the shapes of the first engaging portion 26 and the second engaging portion 27 can be simplified compared to the above embodiment, thereby reducing manufacturing costs. The first component member 1 and the second component member 22 can be assembled separately in order to the bracket body 1. Also, with this configuration, the first engaging portion 26 and the second engaging portion 27 are held by the holding portion 12, and the first component member 21 is pressed toward the second component member 22 by the biasing force of the biasing member 31, so that the first component member 21 and the second component member 22 attached to the bracket body 1 can be prevented from being separated during the sliding operation.

[0055] Fig. 12 is a plan sectional side view of a bracket 100 according to a second modified example of the present invention. Fig. 13 is a CC sectional view of the bracket 100 of Fig. 12.

[0056] As shown in the same figure, in this modified example, the overall shape of the slide block 2 is the same as in the above-mentioned embodiment, but only the part of the slide block 2 that constitutes the operating section 24 is made into the second component member 22, and the other parts are made into the first component member 21.

[0057] The structures of the first engaging portion 26 and the second engaging portion 27 are the same as those of the above-described embodiment, but the two are not held by the holding portion 12 of the bracket body 1, and are prevented from being released from the engaged state by abutting against the top surface of the bracket body 1 in the engaged state. In addition to the second locking portion 23, a claw portion 25 is also provided on the first component member 21 side.

[0058] In this configuration, the materials of the first component 21 and the second component 22 may be the same as those in the above-described embodiment, but instead, the first component 21 may be formed using a relatively inexpensive material such as polyacetal, and the second component 22 may be formed from a transparent resin such as polycarbonate.

[0059] Manufacturing costs can be reduced by forming the first component 21, which occupies a large portion of the slide block 2, from an inexpensive material such as polyacetal. Furthermore, by using a material with high alcohol resistance such as polyacetal for the first component 21, cracks will not occur in the first component 21 and damage to the bracket 100 can be prevented even if the blinds are disinfected with alcohol.

[0060] Additionally, the material, size, shape, and engagement structure of the first component member 21 and the second component member are not limited to those described above or shown in the drawings, and can be changed as appropriate. [Explanation of symbols]
