Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement in a mount for mounting electric components such as a motor and an encoder on an electric blind head box.

[0002]

[Prior art]

 Conventionally, mounts for mounting electric components such as electric blind motors and encoders have been fixed to the bottom surface of the head box by screws that are inserted from below.

[0003]

[Problems to be solved by the device]

 When fixing the mount through the screws from under the headbox, it was not always easy to tighten through the screws because the slat is located near the underside of the headbox. Also, since the head of this screw protrudes from the head box, it not only impairs the appearance of the blade, but it may also scratch and scratch the slat. Further, since the position of the mount is determined by one point, there is a problem that the dimensional tolerance of the longitudinal member such as the shaft becomes severe.

The present invention has been made to solve these problems, and an object of the present invention is to provide an electric motor which can be fixed to the head box from above the head box so that its longitudinal fixed position can be adjusted freely. It is to provide a mount for mounting a blind electrical component.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the means adopted by the present invention is to form at least one set of protrusions on the inner surfaces of the front and rear plates of the head box having an upper opening, and to mount the mounting surface along the lower surface of the set of protrusions. Is formed on the mount, and the mount tightening plate is arranged on the upper surface of the ridge, and the set screw is passed through the mount tightening plate and screwed into the screw hole on the mount fixing surface to fix the mount to the head box.

[0006]

[Action]

 Place the mount tightening plate on the fixed surface of the mount on which the electrical components such as the motor are attached, and pass the set screw through the screw through hole of the mount tightening plate and loosely screw it into the screw hole on the fixed surface. Next, insert the mount into the headbox from the end surface of the headbox, and insert a pair of front and rear ridges on the inner surface of the headbox between the mount fixing surface and the mount fastening plate. In this state, slide the mount in the longitudinal direction of the head rail to a predetermined fixed position, and tighten the set screw firmly there.The pair of front and rear ridges is sandwiched between the mount tightening plate and the mount fixing surface, and the mount is Fix it in the head box. Since the set screw is tightened from the top opening of the head box, the work is easy, and the head of the set screw is located inside the head box and cannot be seen from the outside, so it does not spoil the appearance. Since the fixed position of the mount can be freely adjusted in the longitudinal direction of the head box, it is not necessary to make dimensional tolerances of longitudinal members such as the shaft tight.

[0007]

【Example】

 The mount of the present invention will be described based on an embodiment shown in the drawings. As shown in FIG. 1, front and rear plate portions 11 and 12 of the head box 10 are formed with a pair of protrusions 13 and 14 which protrude inward and extend in the longitudinal direction. A mount fixing surface 17 is formed on the mount 16 carrying the motor 15 along the lower surfaces of the protrusions 13 and 14, and a screw hole 19 into which a plurality of setscrews 18 are screwed is formed in the mount fixing surface 17. A mount fastening plate 20 of approximately the same size and size is arranged on the mount fixing surface 17, and a screw hole 21 is drilled in the mount fastening plate 20. Pass the set screw 18 through the screw hole 21 and screw it into the screw hole 19 of the mount fixing surface 17. First, the set screw 18 is loosely screwed in so that a space slightly larger than the thickness of the protrusions 13 and 14 can be formed between the mount fixing surface 17 and the mount tightening plate 20. Then, as shown by the arrow, the mount 16 is inserted from the end face of the head box 10 so that the protrusions 13 and 14 are fitted between the mount fixing surface 17 and the mount tightening plate 20, and is slid to the mount fixing position. Then, the set screw 18 is tightly tightened, and the ridges 13 and 14 are sandwiched between the mount fastening plate 20 and the mount fixing surface 17 to fix the mount 16 to the head box 10.

Since the set screw 18 is tightened at the opening of the upper surface of the head box 10, there is no obstacle and the work is extremely easy. The head of the set screw 18 is inside the headbox 10 and is not visible to the outside. Since the mount 16 can be fixed at any position in the longitudinal direction of the head box 10, it is not necessary to make the dimensional tolerance of the longitudinal member such as the shaft tight.

In the embodiment shown in FIG. 2, the head box 10 has a large vertical dimension and two sets of ridges 13, 14, 13a, 14a are provided on the upper and lower sides. A mount 16 having a motor 15a for raising and lowering the blind is attached, and a mount 16a having a motor 15a for opening and closing the slat is attached to the lower protrusions 13a and 14b. The shapes and mounting of the mounts 16 and 16a and the fastening plates 20 and 20a thereof are substantially the same as those in FIG.

In the embodiment shown in FIG. 3, a motor 15 and an encoder 25, which are directly connected to both ends of a rotary shaft 24 passing through the head box 10 via couplings 26 and 26 ', are mounted on mounts 16 and 16', respectively. . Each set 16, 16 'is screwed onto the mount fixing surface 17, 17' through a set screw 18, 18 'on the mount fastening plate 20, 20' arranged on the mount fixing surface 17, 17 '. The ridges 13, 14 of the head box 10 are sandwiched between the mount fixing surfaces 17, 17 ′ and the mount fastening plates 20, 20 ′ to fix the mounts 16, 16 ′ to the head box 10.

[0011]

[Effect of device]

 As described above, the mount of the present invention is different from the conventional one that is fixed to the bottom of the head box with a set screw that is passed from the bottom, and the ridges on the front and rear inner surfaces of the head box are sandwiched between the mount fixing surface and the mount tightening plate. Since it is fixed at any position in the longitudinal direction, it is possible to carry out the fixing work without being obstructed by slats, etc., and the head of the set screw is not exposed, so the appearance of the blind is good and the shaft etc. This has an excellent effect that the dimensional tolerance of the longitudinal member does not need to be tight.
