[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a support fitting on a blade plate in a blind shutter.

[0002]

2. Description of the Related Art As shown in FIG. 19, a blind shutter 51 has a frame 53 incorporated in a wall or a ceiling, and a large number of blades 55 are disposed in the frame 53.
Is rotated to adjust the amount of sunlight, or is moved to open and close an opening in the frame 53. A large number of blade plates 55 are connected to each other in a guide 57 via support fittings and the like at both ends of the blade plates 55, and the support plates, chains, link mechanisms, and the like rotate and move the blade plates 55. Numeral 59 indicates a slat storing section. Conventionally, the support fitting is attached to the blade plate 55 by attaching a guide member to both ends of the blade plate 55 with screws or rivets, and engaging the support member with the guide member.

[0003]

Therefore, in the conventional structure, the mounting of the support fitting is troublesome, and the heads of the screws and rivets are exposed on the surface of the blade plate, resulting in poor appearance. The present invention has been devised in view of the above circumstances, and an object of the present invention is to provide a support bracket for a blind shutter in which the heads of screws and rivets are not exposed to the surface of the slats and can be attached with one touch. An object of the present invention is to provide a mounting structure.

[0004]

In order to achieve the above object, the present invention provides a guide groove formed on the back surface of a blade plate and extending in the longitudinal direction of the blade plate, and a guide groove formed on the back surface of the blade plate. A guide wall extending in the direction, an engaging portion formed on the support fitting and capable of engaging with the back surface of the blade plate, and a state in which the engaging portion is formed on the engaging portion and engaged with the back surface of the blade plate. A holder for engaging the guide groove with the engagement groove engaged with the guide wall and engaging the guide groove with the engagement portion engaged with the back surface of the blade plate. A notch is formed near one end of the guide wall of the blade plate in the longitudinal direction, and the guide groove of the support metal is inserted into the engagement groove of the support metal and inserted into the notch. A stopper wall for preventing movement in the direction is formed.

7 has a bent surface portion 109 formed on the end face. A lip material made of rubber or the like is fitted and supported in the groove portion 105. In the figure, A indicates a front surface located on an outer surface of a building or the like, and B indicates a back surface located on an inner surface of a building or the like. Back surface B of the blade 1
At both ends of the curved surface portion 101, guide grooves 111 for the support fittings 3 and 5 are formed to extend in the longitudinal direction of the slat 1 in directions facing each other. A guide wall 11 having a predetermined thickness and a predetermined height is provided at the center on the back surface B of the slat 1.
3 is formed to extend in the longitudinal direction of the blade 1, and a cutout 115 is formed near one end of the guide wall 113 in the longitudinal direction.

[0007] The support fitting 3 provided at one end of the slat 1 in which the cutout 115 is formed is shown in FIGS.
FIG. 7 to FIG. 10 show a support fitting 5 provided at the end of the other blade 1. The support fittings 3 and 5 include a base portion (corresponding to an engagement portion) 401, a shaft portion 403 protruding from the base portion 401, and a connection portion 405 provided at a tip of the shaft portion 403 and connected to a chain, a link mechanism, or the like. Consists of The base 401 has a rectangular shape in plan view, and one surface is a curved surface 401A corresponding to the curved surface 101 of the slat 1,
The other surface is formed by a plane 401B. Connecting part 40
5 is an arm 405A connected to the tip of the shaft portion 403;
Pins 405B protruding from both ends of the arm 405A,
405C.

[0008] The curved surface 401A
Is engaged with the curved surface portion 101 and the guide wall 11 is
3 is formed, and a rectangular notch 409 that extends through the base 401 is formed at an intermediate portion of the engaging groove 407 in the extending direction of the engaging groove 407. Recesses 411 are formed on both sides. This engagement groove 407
As shown in FIG. 4, one of the support fittings 3 is formed to have a predetermined length, a stopper wall 413 is formed between the end of the engagement groove 407 and the end face of the base 401, and the other support fitting 3 is formed. In FIG. 5, it is formed over the entire length of the base 401 as shown in FIG.

As shown in FIGS. 11 to 14, the holder 7 has a flat portion 70 engageable with a flat surface 401B of the base 401.
1, a side portion 703 bent from both ends of the flat portion 701 so as to cover both sides of the base 401, and a guide portion 70 formed at an end of the side portion 703 and engageable with the guide groove 111.
5 is provided. The flat portion 701 is formed with a projection 707 that engages with the cutout 409, and the flat portion 701 is formed with a claw 709 for operating the holder.

Next, attachment of the support fittings 3 and 5 will be described. As shown in FIG. 15, the guide portion 705 is engaged with the guide groove 111, and the holder 7 is fitted to both ends of the slat 1. As shown in FIG. 17, one support fitting 3 inserts the guide wall 113 into the engaging groove 407 and inserts the stopper wall 413 into the cutout 115 at one end of the slat 1. The base 401 of the metal fitting 3 is brought into contact with the curved surface 101, and the holder 7 is slid.
The flat surface 701 of the holder 7 allows the flat surface 40
1B, the support member 3 cannot move in the longitudinal direction of the slat 1 due to the engagement between the notch 115 and the stopper wall 413, and the engagement between the protrusion 707 and the notch 409 and the shaft 4
The holder 7 and the support fitting 3 are integrated by the contact between the end face 403A of the holder 03 and the end face of the holder 7, and the holder 7 and the support fitting 3 are fixed to the end of the slat 1.

As shown in FIG. 18, the guide wall 113 is inserted into the engagement groove 407 of the other support fitting 5, as shown in FIG.
The base 401 of the support fitting 5 is brought into contact with the curved surface 101, and the holder 7 is slid so that the flat portion 7 of the holder 7 is moved.
01 covers the flat surface 401B of the base 401, the protrusion 7
07 and notch 409 and end surface 403A of shaft portion 403
The holder 7 and the end face of the holder 7 are integrated with each other, and the other holder 7 and the support fitting 5 can slide in the longitudinal direction of the slat 1 in an integrated state.

As described above, according to this embodiment, the support fittings 3 and 5 can be attached with one touch.
In addition, since the support fittings 3 and 5 are attached using the guide grooves 111 and the guide walls 113 of the slat 1, screws and rivets are not exposed on the surface of the slat 1 as in the related art, and the appearance is improved. it can. In addition, since one support fitting 3 is fixed to the slat 1 and the other support fitting 5 is mounted so as to be movable in the longitudinal direction of the slat 1, the deformation of the slat 1 due to a temperature change is caused by the movement of the support 5. Absorption can be performed, and rotation and vertical movement of the blade plate 1 can be smoothly performed regardless of a temperature change.

[0013]

[Effects of the Invention] As is apparent from the above description, according to the present invention, a guide groove and a guide wall are formed on the back surface of the blade plate, and the support bracket is attached using the groove and the wall of the blade plate. As a result, the mounting structure of the support fitting can be obtained in which the heads of the screws and rivets are not exposed on the surface of the slat 1 and can be mounted with one touch.
