[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blind bracket for fixing a blind head box to a horizontal surface such as a window frame or a ceiling.

[0002]

2. Description of the Related Art Conventionally, a blind head box is
When fixed to a window frame, ceiling, or the like, it is attached via a bracket. As a structure of the bracket, a horizontal mounting portion which has a substantially L-shaped cross section and is fixed to a horizontal mounting surface,
The mainstream is that having a vertical mounting portion that is fixed to a vertical surface to be attached, and some have only a horizontal mounting portion.

When the head box is fixed by using the bracket, a procedure of mounting the bracket on the mounting surface and then mounting the head box on the bracket is performed. This is because, in the procedure of attaching the head box to which the bracket has been attached in advance, the head box is in the way and cannot be attached.

[0004] Next, the head box is attached to the bracket attached to the surface to be attached. The engaging ridge formed along the direction is engaged by a one-touch engaging mechanism provided on the locking claw, and further, the locking claw is relatively slid along the engaging ridge. Move the head box to the left and right to perform positioning and complete the installation.

As described above, the locking claws of the bracket are pressed in a direction perpendicular to the engaging ridges of the head box, that is, toward the groove bottom of the head box, and are forcibly inserted. The reason for the engagement is that, after the bracket is attached to the mounting surface, the engaging projection of the head box cannot be slid from one end of the engaging claw of the bracket to the engaging claw of the bracket.

The above-mentioned method of attaching the head box to the bracket will be described more specifically.
An L-shaped bracket A having a horizontal mounting portion a and a vertical mounting portion b as shown in (a), and formed below the horizontal mounting portion a so that locking claws c1 and c2 face each other. In this case, as shown in FIG. 3 (b), screws are attached to horizontal or vertical surfaces using screws d, d,..., And then the front side of the head box B (room “R”). Side) is engaged with the locking claw c2 also on the near side, and then the engaging ridge e1 on the other side (window “W” side) is locked with the locking claw on the other side. It is completed by engaging with c1.

The locking claw c1 is integrally formed on one side of a slide block f which slides on the lower surface of the horizontal mounting portion a, and is always urged by a spring i. When the locking claw c1 is pressed by the engaging ridge e1 during this engagement, the locking claw c1 is retracted to the position shown by the imaginary line in accordance with the pressing force. It has a function of restoring the original position when the combination is completed, and this is an example of the above-described one-touch engagement mechanism.

[0008]

However, the above-mentioned prior art has a problem that the manufacturing cost is increased due to the complicated structure of the one-touch engagement mechanism on the bracket side. That is, in the case of the bracket A shown in FIG. 4, the locking claw c2 and the slide block f are formed on a metal sheet cut into a predetermined rectangle.
Forming a slide guide piece g, and a mounting screw hole h,
h .. Then, a separately manufactured slide block f is incorporated with the spring i attached thereto, and the whole is bent into an L-shape, and a slide guide piece g is provided.
It goes through an elaborate processing step of refraction.
Since such a complicated structure is manufactured and used,
This has resulted in considerable costs.

On the other hand, when mounting the blind, first, as described above, after the bracket is mounted on the mounting surface,
It may be difficult to take the procedure of attaching the head box to this bracket.

For example, a trapezoidal window blind is composed of a front main blind and left and right child blinds. When mounting the headbox, in the case of the main blind, the bracket for the mounting surface and the bracket for the bracket are used. The head box is attached in the order, and in the case of a child blind, the head box is connected so that the joint part is inserted into the head box of the parent blind, so the exact mounting position is determined after the connection is made . Therefore, it is necessary to make the above connection in a state where the bracket is attached to the head box in advance, and then to slide the bracket to a predetermined position and attach the bracket to the surface to be attached. Is preferred.

When a procedure is adopted in which a bracket is fixed to a head box with the bracket previously attached to the head box, a bracket having a simple structure suitable for this has not yet been developed. It is the current situation.

The inventor of the present invention does not necessarily need to provide both the horizontal mounting portion and the vertical mounting portion as the basic structure of the bracket.
The present invention has been completed by paying attention to the fact that a simple structure is sufficient to exhibit its function, especially in the case of a small and lightweight bay window blind.

That is, the present invention eliminates such disadvantages of the prior art, and can be employed in any of the above-described mounting procedures.
Another object of the present invention is to provide a head box bracket which has a simple structure and a one-touch engagement mechanism, and which is inexpensive in manufacturing and construction costs.

[0014]

SUMMARY OF THE INVENTION The present invention is directed to a head box having a resilient force in which engaging projections are formed along the longitudinal direction inside the upper edges of both sides of a groove-shaped main body. A blind bracket to be engaged with the engagement ridge, wherein at least one set of locking claws that are opposed to each other along the one direction is provided in the middle of a lower side of the substrate in one direction. The claw is forcibly engaged against the resilient force of the head box when the claw is pressed against the engaging ridge of the head box toward the groove bottom, and is in the engaged state. A horizontal mounting portion having a screw hole is provided on at least one side in one direction of the substrate, and the screw hole of the horizontal mounting portion is provided with the locking claw and the head. Outside the side wall of the head box when the engagement ridge of the box is in the engaged state. The blind bracket ", characterized by being kicked is to its gist.

That is, as a blind bracket,
When this is combined with the head box, the head box has elasticity, while the bracket having only a horizontal mounting portion is employed, and the one-touch engagement mechanism includes a side wall of the head box or the like. Utilizing the elasticity of the head, the locking claws of the bracket are pressed against the outer wall of the engaging ridge, thereby forcibly expanding the space between the engaging ridges of the head box, thereby enabling one-touch engagement. So that
The first is that the locking pawls are slid along the engaging ridges in the engaged state so that the positioning can be performed, so that the overall structure is simplified as a whole and the operation thereof is easy. It is the main point.

Further, the position of the screw hole of the horizontal mounting portion is provided outside the side wall of the head box when the locking claw and the engaging ridge of the head box are in the engaged state, Thus, the point that the head box can be easily attached to the surface to be attached even when the bracket is attached to the head box is defined as a second gist.

The blind bracket according to the present invention has two basic functions, similarly to the conventional bracket. That is, one is a one-touch engagement function between the bracket and the head box, and the other is a positioning function in which the engagement claw can slide along the engagement ridge in the engaged state.

In the present invention, in order to form a head box having elasticity, for example, a steel thin plate formed into a groove shape by sheet metal processing is preferable. It is also possible to adopt a thin molded product molded as a material, and by using such a material having a high rigidity, a resilient force is naturally provided on the side wall and the engaging ridge, etc. Requires no fabrication skills.

The engaging ridge formed on the upper edge of the side wall may be a conventionally known one having an upper edge bent or curved inward. A shape corresponding to this is used.

The horizontal mounting portion of the bracket according to the present invention refers to a portion where a screw hole for fixing the bracket to a horizontal mounting surface is provided and a portion in contact with a mounting surface near the screw hole. Of course, when the bracket is independently attached to the surface to be attached to the blind, the screw holes allow the operation of fixing tools such as tightening of the screws even when the bracket is integrally attached to the head box. It is necessary to be provided in a positional relationship that can be easily performed, and those that cannot be easily operated are not included in the horizontal mounting portion.

The horizontal mounting portion needs to be provided on at least one side of the substrate. If the horizontal mounting portion is provided only on one side, the horizontal mounting portion is naturally located on the room side when mounting on a surface to be adhered. Place and attach so that it is positioned.

The locking claw of the bracket used in the present invention does not necessarily have to be provided integrally with the substrate, and may be formed on the substrate by post-processing such as welding. Processing and forming the substrate itself, as in the brackets described in the examples below, is more excellent in simplicity and speed of manufacture. Further, not only one set of locking claws but also two sets or three or more sets in parallel with each other in the direction of the head box may be used.

Also, since the engaging claws of the bracket are provided so that the directions of the engaging ridges on both sides of the head box with which they are engaged are in the opposite direction, that is, on the inside, the engaging claws are engaged. The direction of the locking claw to be used naturally uses a bracket formed in a direction opposite to the back.

In the present invention, one direction of the bracket refers to a direction connecting the locking claws, and the shape of the bracket in a plan view is usually such that this direction is the longitudinal direction. Can be used in which the direction of the head box is the longitudinal direction, and does not necessarily indicate the longitudinal direction of the bracket.

In the present invention, the screw hole of the horizontal mounting portion is
"Provided outside the side wall of the head box when the engaging claw and the engaging ridge of the head box are in the engaged state."
The reason for this is, of course, that the bracket is attached alone to the blind attachment surface, as well as the operation of the fixing tool such as tightening the screws even when attaching it integrally with the head box This is because a positional relationship that can be reliably performed is set.

[0026]

The blind bracket according to the present invention has a head box to which it is connected and has an engaging ridge and elasticity. On the other hand, the bracket has only a horizontal mounting portion. The locking claw is simply fixed, and the engagement of the locking claw with the head box engaging ridge is performed by pressing the locking claw toward the groove bottom of the head box. Since the head box is forcibly engaged with the resilient force of the head box, the connecting operation is one-touch, and the structure is very simple. It does not require a complicated structure for forced engagement unlike the bracket of the above.

In the blind bracket according to the present invention, the locking claw is slidable along the engaging ridge when the engaging claw is engaged with the engaging ridge of the head box. Adjustment for is possible.

Further, in the blind bracket according to the present invention, the position of the screw hole of the horizontal mounting portion is set to be smaller than that of the side wall of the head box when the engaging claw and the engaging ridge of the head box are in the engaged state. Is also provided on the outside, so if you attach the bracket alone to the surface to be attached, of course, even if it is integrated with the head box, the operation of the fixture on the surface to be attached is reliable. And easily.
