Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement of a bracket for supporting a headbox of a blind.

[Prior Art] A known bracket for supporting a head box in which both upper edges project horizontally outward in a cross section is disclosed in Japanese Utility Model Publication No. 60-41182, etc.
It consists of a main body fixed to a wall surface, etc., a claw provided on the main body so as to be slidable in a direction perpendicular to the longitudinal direction of the head box, and a spring interposed between the main body and the claw to press the claw against the head box. The headbox was supported by hooking both upper edges of the headbox onto a hook at the tip of the main body and a hook at the tip of the claw.

To attach the head box to the bracket, hook the front upper edge of the head box onto the hook at the tip of the main body, push up the rear upper edge along the slanted lower surface of the claw, lower the claw backward, and attach it to the hook at the tip. The removal was accomplished by pushing the slider backwards with a screwdriver or the like and removing the rear upper edge of the headbox from the hook of the claw of the slider.

[Problem that the invention aims to solve] If the headbox is a curtain rail, if the curtain is moved to one side, the area under the headbox will be blank, so push the hook of the headbox backwards from below with a screwdriver, etc. to remove the headbox from the bracket. However, with Venetian blinds where the space below the headbox cannot be left blank, it is not easy to remove the headbox from the bracket by pushing the claw backwards from underneath the headbox.

The present invention was made to solve this problem, and its purpose is to provide a bracket that allows the headbox to be easily removed from the bracket without having to operate from below the headbox. .

[Means for Solving the Problems] In order to achieve the above object, the features of the present invention include hooks formed at the front ends of both side plates of the top plate of the main body, as shown in FIG. , in a bracket that supports the head box by hanging both upper edges of the head box on hooks formed at the rear ends of the claws that are supported by support parts that curve inward from the bottom of the side plate, the upper surface of the top plate is cut down. Provide a protrusion, make a window on both sides of the top plate, make a recess on both sides of the claw, fit the protrusion into it, insert a spring through the window, and insert the front end into the front wall of the recess and the rear end into the protrusion. Press the claw forward with a spring to firmly grasp the head box between the front and rear hooks, and provide an operating section protruding from the top plate at the center of the front end of the claw, and push the operating section backward to release the head box from the bracket. The reason is that it was made to come off.

The distance between the straight line connecting the lower end of the protrusion and the front end of the top plate and the rear end of the support part is made to be equal to or slightly larger than the thickness of the rear wall of the claw recess, and the claw is inserted from the front side of the top plate. It is desirable to install it.

[Function] Hang the front upper edge 11 of the head box 10 on the hook of the main body 20, and then hook the rear upper edge 12.
When the head box 10 is lifted against the spring 40 while pressing against the inclined lower surface of the hook of the claw 30, the claw 30 slides rearward, so that the upper edge 12 on the rear side easily hangs on the hook of the claw 30. spring 40
Since the claws 30 are always pressed forward, the head box 10 is firmly supported by the two hooks.

When the operating part of the pawl 30 is pushed against the spring 40 from the front of the bracket supporting the head box 10, the hook of the pawl 30 is shifted rearward, and the rear upper edge 12 of the head box 10 is automatically released from the hook. Since it comes off easily, the head box 10 can be easily removed from the bracket.

In this manner, there is no need to insert hands or tools into the rear of the headbox 10 when attaching or removing the headbox 10 from the bracket.

[Example] The bracket of the present invention will be described based on an example shown in the drawings.

As shown in Figures 1 to 4, the main body 20 made of sheet metal consists of a horizontal top plate 21 and a vertical rear plate 22 that are integrally molded, and the rear plate 22 and the top plate 21 are fixed to the wall. Mounting holes 23, 24 for
can be opened. Both sides of the upper surface of the upper surface plate 21 are partially cut down to form protrusions 26 . A window 28 is formed in a portion in front of the protrusion 26 of both side plate portions 27 which bend downward of the top plate 21, and a hook 29 is formed in the front end portion. Head box 10 of both side plate parts 27
The length of the central portion of the lower edge that fits inside the head box 10 is equal to or slightly smaller than the inner width of the head box 10.

The claw 30 is made of synthetic resin, and has an elongated hole 34 in the center corresponding to the mounting hole of the upper plate portion 21. An operating portion 31 is provided at the center of the front end of the claw 30, and a hook 39 is provided below the center of the rear end. Recesses 32 are provided on both sides of the claw 30. As shown in Figure 3, the claw 3
0 is supported by both support portions 15 that bend inward from the bottom of the center of both side plate portions of the main body 20. The gap between both supporting parts 15 is set to be slightly larger than the width of the hook 29 of the claw 30.

The distance between the line connecting the front end of the top plate 21 and the protrusion 26 and the rear end of the support part 25 is set to be equal to or slightly larger than the thickness of the claw 30 excluding the hook 39, so that the top plate 21 claw 30 from the front end of
is inserted diagonally onto the support portion 25, the claw 30 is easily attached to the top plate 21, and the protrusion 26 is fitted into the recess 32. The lower surface of the hook 39 of the pawl 30 is formed into a slope 38 that descends rearward. After attaching the pawl 30 to the top plate 21, the spring 40 is inserted into the recess 32 of the pawl 30 through the window 28. The front end of the spring 40 hits the front wall 37 of the recess 32, and the rear end hits the protrusion 26, respectively, and presses the claw 30 forward.

Next, attaching and detaching the head box will be explained. As shown in FIG. 5, first, attach the front upper edge 11 of the head box 10 to the hook 29 of the main body 20.
Multiply by At this time, the claw 30 is pushed forward by the spring 40, the operating portion 31 protrudes from the front end of the main body 20, and the rear wall 36 of the recess 32 comes into contact with the protrusion 26. When the head box 10 is pushed up around the upper edge 11 as shown by the arrow, the rear upper edge 12 hits the slope 38 of the hook 39 of the claw 30, and the claw 30 moves backward against the spring 40. , the upper edge 12 automatically hangs on the hook 39,
The state shown in FIG. 1 is reached. Since the hook 39 of the pawl 30 is always pushed toward the hook 29 of the top plate 21 by the spring 40, the head box 10 is firmly supported by the two hooks. Since the center portions of the lower edges of both side plates 27, which are equal to or slightly narrower than the inner width of the head box 10, fit inside the head box 10, both upper edges 11 and 12 of the head box 10 are stable and will not fall inward. .

As shown in FIG. 6, when both upper edges 11 and 12 of the head box are supported by the hooks 29 and 39, the operating portion 31 of the claw 30 protruding from the front of the bracket is pressed against the spring 40. When pressed, the claw 30 is displaced rearward and the rear upper edge 12 of the headbox 10 is automatically released from the hook 39, allowing the headbox 10 to be easily removed from the bracket.

In this way, there is no need to put hands or tools behind the headbox 10 when installing or removing the headbox 10, and all operations can be performed only from the front side of the headbox 10, so it can be used like a Venetian blind. The headbox can be easily attached to and detached from the bracket even when the slats are suspended from the headbox.

[Effects of the invention] As mentioned above, the bracket of the present invention differs from the conventional bracket in which the headbox could not be removed from the bracket without inserting the hand behind the headbox and operating the claw. This has an excellent effect in that the head box can be removed from the bracket simply by pushing the protruding operation part.
