Description

[Detailed description of the invention] [Field of industrial application] The present invention is a bracket used for fixing the head box of a blind to a window frame or wall surface, etc. in order to attach horizontal blinds, vertical blinds, curtains, etc. In particular, the present invention relates to a blind bracket used to attach a head box of a blind, which has mounting edges formed along the upper edges of the left and right side walls.

[Conventional technology]

The bracket used for attaching the head box of the blind to the window frame or wall surface has a vertical support piece and a horizontal support piece pivoted to the tip of the top plate and the tip of the side plate, respectively, of the L-shaped bracket. A commonly used bracket has a structure in which the tips of the horizontal support piece and the horizontal support piece are hooked to each other to form a rectangular frame, and the head box is surrounded and supported within the rectangular frame. To install a blind using such a bracket, you must hold the headbox near each end of the headbox and attach it to the bracket, so at least two people are required to install one blind. And the workability is poor.

In order to overcome these drawbacks, a bracket has been proposed that allows the head box to be attached and detached in one-touch manner, as disclosed in, for example, Japanese Utility Model Application Publication No. 58-35597. In this case, a sliding frame is slidably arranged under the horizontal frame of the L-shaped bracket body, and the horizontal frame and the lower side of the sliding frame are engaged with a ridge provided on the upper edge of the head box. The headbox is supported by forming a mating hook and hooking the flange of the headbox onto the hook. In this type of bracket, a spring is placed between the horizontal frame of the bracket body and the sliding frame, and when installing the headbox, at least two brackets must be attached to the window frame or wall in advance. The headbox is fixed, and the protrusion at the top of one side of the headbox is hooked onto the hook of one of these brackets, and then the protrusion at the top of the other side of the headbox is pushed into the other hook of the bracket. Therefore, the head box can be attached extremely easily. In this case, the head box can be installed by one person, and work efficiency is improved compared to the case where a conventional bracket is used.

However, with the above type of bracket, it is difficult to remove the headbox from the bracket after the headbox is attached to the bracket. In the bracket disclosed in the above-mentioned Japanese Utility Model Publication No. 58-35597, a drawer tool hook is attached to the sliding frame (block plate in the publication), and the drawer tool is hooked onto this to allow the slider to slide. By pulling out the frame from the horizontal frame of the bracket main body, one of the hooks can be removed from the mounting flange of the headbox. However, with such a structure, it is difficult to hang the drawer tool on the drawer tool hook part, and it is also difficult to perform the drawer operation.

As a means to solve such drawbacks in the bracket, the present applicant has developed a bracket for attaching the head box of a blind to a window frame or wall surface, in which mounting edges are formed along the upper edges of the left and right side walls. , a bracket body including a horizontal frame portion and a vertical frame portion; a horizontal sliding frame slidably engaged with the lower side of the horizontal frame portion; and a bracket body slidably engaged with the inside of the vertical frame portion. The bracket main body and the horizontal sliding frame each have an engaging member that engages with and supports a mounting ridge formed on the upper edge of the head box. A mating portion is provided, an inward hook portion is provided at the inner end of the horizontal sliding frame, and a claw that elastically engages with the hook portion is formed on the lower side of the horizontal frame portion of the bracket body. and a cam surface on the upper end of the vertical sliding piece that elastically pushes open the hook portion to release the engagement with the claw by pushing up the sliding piece, and the claw. A bracket for blinds has been devised, which is characterized by forming a cam surface that pushes outward the horizontal sliding frame whose hook portion is disengaged. (Utility Application No. 10387 of 1981) [Purpose of the invention] The present invention is a blind bracket that was previously devised by the applicant as described above, and which has been further improved to have a simpler structure and be manufactured at a lower cost. To provide a bracket for a blind in which the head box of the blind can be easily attached and the head box can be easily removed.

[Summary of the idea]

A feature of the blind bracket according to the present invention is that in the bracket for attaching the head box of the blind, which has mounting edges formed along the upper edges of the left and right side walls, to a window frame or wall surface, the horizontal frame portion and the vertical frame portion are a horizontal sliding piece that can be slidably engaged with the lower side of the horizontal frame; and a vertical sliding piece that can be slidably engaged with the inside of the vertical frame. The above-mentioned bracket main body and the above-mentioned horizontal sliding piece are each provided with an engaging portion that engages with and supports the mounting ridge formed on the upper edge of the above-mentioned head box, and the above-mentioned horizontal A downward hook is provided at the inner end of the sliding piece, and
The bracket body is formed with a locking portion that elastically engages with the hook portion to lock the horizontal sliding piece, and is configured to push the sliding piece up onto the upper end of the vertical sliding piece. Therefore, a cam surface is formed that pushes up the hook to disengage the hook from the locking portion and also pushes the horizontal sliding piece outward.
