Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wall fastening device for pressing and fixing the headbox of a blind against a wall using the force of a spring. More specifically, it relates to an improvement in the structure of the other end of the headbox when a spring is provided only at one end of the headbox.

[Prior Art] As a wall mounting device of this type, the applicant has developed a wall mounting device in which the central part of a wall board is partially rotatably fitted to the outer end of a support shaft protruding from the end cap of a head box of a blind. The wall device was filed under Utility Application No. 71742/1983. This device is capable of bringing the wall board into close contact with the entire wall surface even if the wall surface is not perpendicular to the support axis of the blind.

[Problems to be solved by the invention] However, since the above-mentioned conventional wall mounting device is configured so that the wall mounting plate can be partially rotated in all directions around the support shaft, it is difficult to pull down the operation cord of the blind. As a result, the head box may also tilt downward about the support shaft, and in this case, there is a problem in that the blind cannot be raised and lowered smoothly.

Furthermore, since the conventional wall attachment device has a structure in which the support shaft protrudes from the end cap, the end cap has to form a thick support part that extends to some extent into the end of the head box in order to support the support shaft. The problem is that the space within the headbox is blocked and the width of action of the blind is narrowed.

The object of the present invention is to provide a headbox mounting device that prevents the headbox from tilting even when the operating cord of the blind is pulled down, and that can effectively utilize the end space within the headbox to widen the range of action of the blind. do.

[Means for solving the problem] The present invention is configured so that the wall plate can be rotated only around an axis parallel to the vertical direction of the blind at the end face of the end cap, and cannot be rotated in other directions. This is what I did. Since the wall plate can only be rotated around an axis parallel to the vertical direction of the blind,
If the wall surface is inclined at the front and back so that there is a difference between the front width and the depth width, when this wall board is pressed against the wall surface, it will rotate and the wall surface will automatically tilt at the same angle as the wall surface. and fully adheres to the wall surface.

Furthermore, if the insertion member is provided protrudingly behind the mounting surface of the mounting wall plate, and the clamping member is rotatably held on the end face of the end cap, more space can be created within the end cap. .

[Example] Next, an example of the present invention will be described in detail based on the drawings.

In FIG. 1, an end cap 2 is fitted into one end of a head box 1. A wall plate 3 is supported by the end cap 2 so as to be rotatable only in a predetermined direction. Further, an end cap equipped with a wall mounting device that expands and contracts with a spring is fitted to the other end of the head box 1 (not shown).

As shown in FIGS. 2 to 4, a tapered recess 3 is provided at the center of the back surface of the wall surface 3a of this wall board 3.
1 is formed, and an insertion member 32 protrudes within this recess 31 and on both sides of the recess 31. This insertion member 32 has a chevron-shaped plate shape, and is provided so as to protrude with its plate surface in the horizontal direction. Furthermore, claws 33, 33 are protruded from the center base of the insertion member 32 and are engaged with a clamping member of the end cap 2, which will be described later.

Further, as shown in FIGS. 5 to 10, tapered holding members 21, 21 are protruded from the end surface 2a of the end cap 2. As shown in FIGS. These clamping members 21,
21 has locking holes 22, 22 formed in the vertical direction, respectively. The holding members 21, 21 are arranged so that the interval therebetween is equal to the thickness of the insertion member 32, so that the insertion member 32 can be inserted therein. The locking holes 22, 22 are for locking the claws 33, 33 when the insertion member 32 is inserted. 2
4 is a groove into which the edge of the head box is inserted.
The above-described shapes of the end cap 2 and the wall plate 3 are formed by plastic molding.

[Function] To assemble the device having such a configuration, as shown in FIG. 33, 33 are the locking holes 22,
22 and lock it. The shaft 4 through which the claws 33, 33 pass is the vertical direction of the blind (arrow in Fig. 1).
The wall plate 3 is rotatably attached to the shaft 4, which is parallel to the shaft 4. Since the insertion member 32 is plate-shaped, it does not rotate in any direction other than around this axis 4.

Press this device against a wall surface that is sloped at the front and back and has a difference in front width and depth width.
When it is pressed against the wall surface, it rotates and the wall-attached surface 3a naturally inclines at the same angle as the wall surface, and comes into close contact with the entire surface of the wall. With this device, the headbox 1 is brought into close contact with the wall surface, so that the headbox itself will not tilt downward even if an operating cord (not shown) is pulled down.

Further, since the insertion member 32 and the clamping member 21 are configured to bite into the interior of the end cap 2 and the wall plate 3, respectively, the end surface of the end cap 2 and the wall surface 3a of the wall plate 3 are In addition to being able to shorten the distance, the base of the clamping member 32 only slightly protrudes inward from the end cap 2, as shown in FIGS.
By fitting the end cap 2, the usable space is not narrowed.

In addition, in the above example, the holding member is provided on the end cap and the insertion member is provided on the wall plate, but
The rotating mechanism may be constructed in the same manner as in the above example by providing an insertion member on the end cap and a clamping member on the wall plate.

[Effects of the invention] As described above, according to the wall mounting device of the present invention, by configuring the wall mounting plate to rotate only around an axis parallel to the vertical direction of the blind,
When the operating cord of the blind is pulled down, the head box does not tilt downward as well, unlike in conventional wall mounting devices.

Further, by providing the end cap itself with a locking portion for connecting to the wall plate, there is an effect that the end space within the head box can be effectively utilized and the working width of the blind can be widened.

In particular, if the insertion member is configured to be rotatable by providing an insertion member protruding behind the mounting surface of the mounting wall plate and a clamping member protruding from the end face of the end cap, the end space in the head box can be further saved. It can be expanded further.
