Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a top box mounting device for blinds, and more particularly to a mounting device that allows a blind top box to be mounted to a bracket at its installation location in a single touch.

Conventional technology and its problems Conventionally, a blind top box mounting device with such a one-touch mounting function has a pair of front and rear tension or clamp-type engaging claws, at least one of which is given spring elasticity. A structure is known in which the hook is provided on a bracket at a blind installation location, and the hook is forcibly pressed against the hook so that the hook is snapped into the engaged portion of the blind top box by its spring elasticity. In this type of conventional device, a pair of hooking claws use spring elasticity to push or pinch the blind top box and hold it in place, so it is not possible to secure it securely with this alone, and the blind top box may wobble or move in the length direction. There is a possibility that it may shift. In order to avoid this, after the blind top box is engaged, it is necessary to set the engagement claw on the bracket using a set screw or the like so that it does not move, which is a tedious work.

The purpose of this invention is not only to allow the blind top box to be attached to the bracket at the installation location in a single-touch manner, but also to ensure that the blind top box is installed securely without wobbling or shifting in the length direction without the aid of set screws or the like. The purpose is to provide a top box mounting device for the blinds that can be installed underneath.

Means for Solving the Problems The top box mounting device for blinds of the present invention has an upper semi-tubular shape with horizontally extending socket-shaped parts with inwardly facing lips at the lower ends of both walls protruding from the entire surface side. The structure includes a bracket fixed to the building side, and an insert block inserted into the socket-shaped part of the bracket,
The inner space of the bracket socket-shaped portion has a shape and dimensions to support the insert block from all sides, top, bottom, left and right, with a slight clearance around the periphery, and the insert block protrudes downward and is connected to the lip portion. It has a pair of front and rear claws with a left and right width that can pass through the grooves between the blind top box. The tip of the semi-tubular curved edge of the mold is suspended when the box is attached, and the pair of claws has an inclined surface forming an inverted V-shape when viewed from the front, and under this suspension, the bracket socket is When the insert block is inserted into the shaped part, the claw part is sagging to a degree that presses the curved edge of the blind top box from above and below between the lower surface of the bracket socket and the sloped surface of the claw part at the part facing the upper surface of the edge. The bracket is preferably made of metal and the insert block is made of plastic.

Embodiments Next, embodiments of the present invention will be described with reference to the accompanying drawings.

The bracket 3 fixed to the building side has an upper semi-tubular shape and has inward lip parts 31 at the lower ends of both walls.
A horizontally extending socket-shaped portion 2 with 31 is provided protruding from the front side, and the socket-shaped portion 2 of the bracket 3
The insert block 4 inserted into the inner space 5 has a pair of front and rear claws that protrude downward at a predetermined degree of drooping described later and have a left and right width that can pass through the groove 1 between the lip parts 31. 6,6 attached. The bracket 3 has a shape and size such that the inner cavity of the socket-shaped portion 2 has a slight clearance around the periphery to support the insert block 4 from all four sides, top, bottom, right and left. The tips of edges 8, 8, which extend in the length direction of both side shoulders of the blind top box 7 and are curved inward into an upper half-tube shape, are attached to the claws 6, 6, respectively, of the box 7. Forms inclined surfaces 9, 9 on which the frame is hung. The inclined surfaces 9, 9 are
The pair of claws 6 and 61 form an inverted V-shape when viewed from the front. The above-mentioned claws 6, 6 are inserted into the inner space 5 of the bracket socket-shaped part 2 under the suspension of the front curved edges 8, 8, so that the blind top box curved edges 8, 8 is the degree of droop that corresponds to the pressing from above and below between the lower surface of the bracket socket-shaped portion 2 at the portion facing the upper surface of the edges 8, 8 and the sloped surfaces 9, 9 of the claw portions.

In the figure, the reference numeral 10 designates an anchor with a spring-type base 11 formed in the insert block 4, which anchor 10 is inserted into the inner cavity 5 of the bracket socket-shaped part 2 so that the spring of the base 11 is fixed. It snaps into engagement with the engaging stepped portion 12 of the bracket socket-shaped portion 2 with elasticity, and serves to prevent the insert block 4 from coming off. The insert block 4 can be removed from the bracket socket 2 by pushing the anchor 10 out of the engagement step 12 and pulling out the insert block 4.

Function The function of the present invention will be described as follows with reference to the symbols in the drawings.

According to the present invention, the inclined surfaces 9 of the claws 6, 6 are provided in the inner space 5 of the socket-shaped portion 2 of the bracket 3, which is fixed to the building side by screws or other suitable means at the location where the blind top box is installed. By pushing the insert block 4 on which the blind top box 7 is suspended at the tips of the semi-tubular curved edges 8, 8 into the bracket 9, the sloped surface 9 of the claw part of the insert block 4 in the bracket socket shaped part 2 is inserted. , 9 and the lower surface of the bracket socket-shaped portion 2, the curved edges 8, 8 are pressed from above and below, thereby closing the blind top box 7.
can be attached to the bracket 3 in one touch.

In this way, in the present invention, the ends of the semi-tubular curved edges 8, 8 of the blind top box 7 are suspended from the inclined surfaces 9, 9 of the claws 6, 6 of the insert block 4, and the curved Since the edges 8, 8 are pinched from above and below between the inclined surfaces 9, 9 of the claw portions and the lower surface of the bracket socket-shaped portion 2, the pinching pressure is applied to the curved edges 8, 8 on the side of the bracket socket-shaped portion 2. On the apex line, the pinching points are applied at the tips of the curved edges 8, 8, which are the portions of the claws 6, 6 that are deviated diagonally downward from the apex line. This results in a pinching pressure that is relatively shifted to the left and right in FIG. In other words, the claws 6, 6 can restrain the curved edges 8, 8 in a wedge-like manner. Moreover, this claw part 6,6
The wedge-like restraint is effective because the claws 6 are symmetrical (the inclined surfaces 9, 9 are in an inverted V-shape) as a pair in the front and rear, and work synergistically. Therefore, according to the present invention, it is guaranteed that the blind top box 7 can be attached to the bracket 3 extremely firmly without wobbling or shifting in the longitudinal direction without using any set screws or the like. As a result of the curved edges 8, 8 being compressed and restrained in a coupled and effective manner, the insert block 4 is also firmly restrained against the bracket socket-shaped portion 2 using the claws 6, 6 as a restraining medium. be done. Furthermore, the insert block 4 does not move in the longitudinal direction of the blind top box 7.

In the present invention, the sloped surfaces 9, 9 for hanging the tips of the curved edges 8, 8 of the blind top box 7 are formed on the claws 6, 6 by designing the slope angle θ appropriately in advance. By doing so, the same insert block 4 can be used for mounting multiple types of blind top boxes having different dimensions in terms of thickness. For example, if the inclination angle θ with respect to the vertical line is
It can be used for multiple types of blind top boxes (however, the radius of the curved edges 8, 8, the opposing distance, and the height of the box 7 are the same) with a thickness of 0.4 to 1.5 mm in the range of about 20 to 30 degrees. .

In the present invention, the bracket socket-shaped portion 2 is formed into an upper half-tube shape with inwardly directed lip portions at the lower ends of both walls, and the claw portions 6 are connected to the lip portions 31 and 3.
The left and right width that allows the insert block to pass through the grooves 1 between the brackets 1 and 1 is necessary because the insert block 4 is equipped with claws 6, 6. The reason why the space 5 is shaped and dimensioned so as to support the insert block 4 from all sides, top, bottom, right and left with a slight clearance around it is to achieve the desired coupling and effective sandwiching of the curved edges 8, 8. This is necessary to perform the required insertion of the insert block 4 with pressure restraint.

Effects of the invention As described above, according to the invention, it is possible not only to attach the blind top box to the bracket at the installation location in a single touch, but also to prevent wobbling and lengthwise movement of the blind top box without the aid of set screws or the like. This can be done under firm conditions without any deviation.
