  A bracket described in Patent Document 1 is known as a conventional blind mounting device. The bracket shown here is formed by forming claws that project inwardly at the lower part of both legs of the U-shaped frame that opens downward. After fixing the bracket in place, the blind headbox When the head box is elastically pushed from the bottom to the inside through the opening of the bracket, the head box enters the bracket, and the lower part of the head box is placed and held on the nail, so that the head box is attached to the bracket. It is done.

Japanese Utility Model Publication No. 57-124599

  However, if the head box is held only by the claws of the bracket, there is a possibility that the lower part of the bracket is expanded during the operation of the blind, and there is a risk that the lower part of the head box will come off the claws and fall from the bracket. For this reason, in Patent Document 1, a holding member is provided on one leg of the bracket via a hinge member, the holding member is elastically engaged with the other leg, or a perforation is provided on both legs of the bracket. It has been proposed to prevent the lower portion of the bracket from expanding by inserting both end portions of separate U-shaped holding metal fittings into both holes.

  As described above, in order for the bracket to stably hold the head box, after performing the work of pushing the head box from below the bracket, the work of engaging the holding member and inserting the holding metal is further performed. There is a problem that the workability becomes very troublesome because it is necessary and the mounting work becomes two actions. In addition, when the mounting location is small, there is a problem that the holding member or the holding fitting cannot be engaged or inserted, and there is a possibility that the mounting cannot be performed.

  The present invention has been made in view of such a problem, and an object of the present invention is to provide a blind mounting device that can easily mount the blind to a fixed surface even in a narrow mounting location. .

In order to achieve the above-described object, the present invention comprises a bracket fixed to a fixed surface such as a window frame, and a support member that supports the shielding material so as to be opened and closed, and the support member is attached to the bracket. In a blind mounting device for mounting a blind on a fixed surface,
The support member includes front and rear wall portions, and at least one wall portion of the front and rear wall portions is provided with a rib projecting downward at a lower portion thereof,
The bracket has a top plate portion fixed to the fixed surface and front and rear plate portions hanging from the front and rear of the top plate portion, and has a substantially U-shaped shape that opens downward, and a support member in the bracket from the lower opening of the bracket The folding part that supports the supporting member is formed at the lower end of the front and rear plate part, and at least one folding part is fitted with the rib of the supporting member to restrict the displacement in the front-rear direction. It is a hook part.

Further , the hook portion is folded upward.

Further , an elastic body is provided in the bracket, and the elastic body biases the support member so as to press the rib against the hook portion.

Furthermore , the elastic body is a leaf spring portion formed by cutting and raising a part of the top plate portion and / or the front and rear plate portions of the bracket.

Furthermore , an operation part that projects downward from the hook part is provided at the lower part of the front and rear plate part, and the space between the front and rear plate parts can be expanded by operating the operation part.

  According to the present invention, the support member can be attached to the bracket simply by pushing the support member from the lower side to the upper side in a substantially vertical direction without tilting the support member. Therefore, the work can be easily performed even in a small installation place. it can. The lower part of the bracket is prevented from expanding by fitting the rib on the lower part of the support member and the hook part to restrict displacement in the front-rear direction of the plate part provided with the hook part fitted to the rib. It is possible to prevent the support member from being inadvertently detached. In this way, it can be attached with few actions, and attachment work is easy.

  Moreover, since the force which presses the rib of a supporting member to the hook part of a bracket with an elastic body is added to a supporting member, while fitting with a rib and a hook part is maintained reliably, a supporting member is pressed down with an elastic body. Thus, it is possible to prevent the lateral displacement of the support member during operation or the like. Further, by lifting the support member in the bracket against the urging force of the elastic body, the rib can be detached from the hook portion, and the holding of the support member by the bracket can be released.

  By using the elastic body as a leaf spring portion formed by cutting and raising a part of the bracket, the number of components can be reduced and it can be manufactured at low cost.

  Further, by providing the operation portion, the operation portion can be operated and the front and rear plate portions of the bracket can be easily expanded, so that the support member can be easily removed.

  Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. In the blind 16 to which the first embodiment is applied, when the outer window 10 arranged on the outdoor side and the inner window 12 arranged on the indoor side are installed in the window frame as in the example shown in FIG. A small gap 14 (for example, about 30 mm) formed in the gap 14 is attached to the fixed surface 18 of the window frame above the gap 14 by a blind attachment device.

  This blind mounting device includes a bracket 20 and a head box 24 as a support member that supports a slat (shielding material) 22 of the blind 16 so as to be opened and closed.

  The raising and lowering and rotating operations, which are the opening and closing operations of the slats 22, can be performed by a known mechanism. That is, regarding the raising / lowering operation of the slat 22, one end side is inserted into the slat 22 and connected to the bottom rail below the slat 22, and the other end side is operated from the raising / lowering cord hanging from near one end of the head box 24. Can be raised to the raised position shown in FIG. 2, or lowered to the lowered position shown in FIG. As for the rotation operation of the slat 22, a dial provided at one end of the head box 24 is rotated with a finger from the lower side of the head box 24, or an operation cord hanging from one end of the head box 24 is operated. Accordingly, the ladder cord supporting the slat 22 can be tilted to be in a horizontal state as shown in FIG. 1 or in a vertical state as shown in FIG.

  As shown in FIG. 3, the head box 24 has a box shape including front and rear wall portions 24a and 24b and a bottom wall portion 24g, and the bottom of the front and rear wall portions 24a and 24b is lower than the bottom wall portion 24g. Also, ribs 24c and 24d are respectively extended downward. Further, the upper end portions 24e and 24f of the front and rear wall portions 24a and 24b extend by being folded back 180 degrees toward the inner side facing each other and downward. An elevating cord or a ladder cord for opening and closing the slat 24 passes through a hole (not shown) formed in the bottom wall portion 24g.

  On the other hand, the bracket 20 includes a top plate portion 20a fixed to the fixing surface 18 with screws 19, and front and rear plate portions 20b and 20c that respectively hang from the top plate portion 20a in the front-rear direction. The head box 24 can be received from the lower opening 20h. Further, the lower ends of the front and rear plate portions 20b and 20c are formed with folded portions that are folded inwardly facing each other, and the folded portions are hooks having a substantially U-shaped cross section that is folded upward 180 degrees. The parts are 20d and 20e. The hook portions 20d and 20e have shapes that can be fitted into the ribs 24c and 24d of the head box 24, respectively.

  Further, the bracket 20 is provided with leaf spring portions 20f and 20g formed by cutting and raising a part of the boundary portion between the top plate portion 20a and the front and rear plate portions 20b and 20c, respectively.

  Next, a procedure for attaching the head box 24 to the bracket 20 will be described with reference to FIGS.

  First, as shown in FIG. 6A, the top plate portions 20 a of a plurality of brackets 20 that are appropriately separated from the fixed surface 18 in advance are attached with screws 19. Then, the head box 24 is positioned directly below the lower opening 20h of the bracket 20, and the head box 24 is lifted in a substantially straight vertical direction as indicated by an arrow A in FIG.

  Thereafter, as shown in FIG. 6B, when the upper end portions 24e and 24f of the head box 24 begin to be inserted into the bracket 20 from the lower opening 20h, the hook portions 20d and 20e of the bracket 20 are moved forward and backward of the head box 24. Although it abuts against the wall portions 24a and 24b, when the head box 24 is further pushed in the direction of arrow A in FIG. 4, the hook portions 20d and 20e of the bracket 20 are pushed outward by the front and rear wall portions 24a and 24b of the head box 24. Thus, the front and rear plate portions 20b and 20c are slightly displaced from the position indicated by the two-dot chain line in FIG. 6 (b) to the position indicated by the solid line.

  When the head box 24 is further pushed in, the upper end portions 24e and 24f of the head box 24 come into contact with the leaf spring portions 20f and 20g of the bracket 20 as shown in FIG. 6C, but the leaf spring portions 20f and 20g When the head box 24 is pushed up against the urging force, the leaf spring portions 20f and 20g are pushed up from the position indicated by the two-dot chain line in FIG. 6C to the position indicated by the solid line.

  When the head box 24 is pushed in while pushing up the leaf springs 20f and 20g, the ribs 24c and 24d are in a state of getting over the hook portions 20d and 20e as shown in FIG. 6 (d). At this time, the distance between the front and rear plate portions 20b and 20c of the bracket 20 is reduced by the restoring force from the position of the two-dot chain line in the drawing to the position of the solid line.

  Thereafter, when the ribs 24c and 24d completely get over the hook portions 20d and 20e, when the hand box is released and the force for pushing it is released, as shown in FIGS. 5 and 6 (e), The head box 24 is lowered, and the ribs 24c and 24d are fitted into the hook portions 20d and 20e. As a result, the distance between the front and rear plate portions 20b and 20c of the bracket 20 is reduced from the position of the two-dot chain line in the drawing to the position of the solid line, and the leaf spring portions 20f and 20g are displaced from the position of the two-dot chain line in the drawing to the position of the solid line. To do. Thus, in the state where the ribs 24c and 24d are fitted to the hook portions 20d and 20e, the leaf spring portions 20f and 20g press the upper end portions 24e and 24f of the head box 24, and the position of the head box 24 is fixed. Installation is complete.

  As described above, the attachment is completed simply by pushing the head box 24 into the bracket 20 upward in the vertical direction, and the attachment can be easily performed with one action. The head box 24 can be mounted without being tilted, and the amount of displacement of the front and rear of the bracket 20 is small, so that the work can be easily performed even in a place where the depth of the mounting place is narrow.

  After the mounting, the ribs 24c and 24d are fitted to the hook portions 20d and 20e, so that the head box 24 is restricted from moving downward, and the front and rear plate portions 20b and 20c of the bracket 20 are displaced in the front-rear direction. Is prevented and the lower opening 20h is prevented from expanding, so that the head box 24 can be prevented from being inadvertently detached. Further, a force that presses the ribs 24c and 24d of the head box 24 against the hook portions 20d and 20e by the leaf spring portions 20f and 20g is applied to the head box 24, whereby the ribs 24c and 24d and the hook portions 20d and 20e While maintaining the fitting securely, pressing the head box 24 in the vertical direction can prevent lateral displacement of the head box 24 during operation or the like.

  Further, since the ribs 24c and 24d are present, the gap between the head box 24 and the shielding material 22 can be closed, so that the light shielding property can be improved.

  Next, a procedure for removing the head box 24 from the bracket 20 will be described with reference to FIG.

  As shown in FIG. 7A, when the head box 24 is removed from the state attached to the bracket 20, as shown in FIG. 7B, the head box 24 resists the urging force of the leaf spring portions 20f and 20g. Push upward. As a result, the leaf spring portions 20f and 20g are displaced from the position indicated by the two-dot chain line in FIG. 7B to the position indicated by the solid line, and the head box 24 is moved to a position where the ribs 24c and 24d are detached from the hook portions 20d and 20e. To rise.

  Next, as shown in FIG. 7C, with the head box 24 pushed in upward, the front and rear plate portions 20b and 20c of the bracket 20 are spread in the front-rear direction with fingers or the like to widen the lower opening 20h. Let it open. At this time, a finger can be inserted and pushed from the lower side of the bracket 20 and the amount of expansion can be small, so that a gap in the depth direction is formed between the front and rear plate portions 20b and 20c of the bracket 20 and the periphery thereof. Work can be performed even when there is not.

  Then, as shown in FIG. 7D, the head box 24 is pulled out from the expanded lower opening 20h while the front and rear plate portions 20b and 20c of the bracket 20 are pushed and expanded. As a result, the upper end portions 24e and 24f of the head box 24 are separated from the leaf spring portions 20f and 20g, so that the leaf spring portions 20f and 20g are displaced from the position of the two-dot chain line in the drawing to the position of the solid line.

  Thereafter, as shown in FIG. 7E, when the head box 24 is completely pulled out from the bracket 20, the removal is completed.

  As described above, when the head box 24 is removed, the head box 24 basically needs to be moved substantially in the vertical direction, and the amount of expansion of the bracket 20 is small. It can be carried out.
