Description

  The present invention relates to a technical field of a wiring fixing structure in an electric shutter device for building installed in an opening of a house or a building.

In general, in an electric shutter device for construction, left and right ends of a winding drum around which a shutter curtain is wound are rotatably supported by left and right support brackets constituting a shutter case, and a winding based on driving of an electric switch is performed. Some are configured to unwind and open the shutter curtain by forward and reverse rotation of the take-up drum, and open and close the opening. In this case, for example, an electric switch is provided in the cylinder of the take-up drum. In such a case, the electric wire connected to the electric switch may be arranged along the left and right inner side surfaces of the left and right support brackets. When the electric wires are arranged along the left and right inner side surfaces of the left and right support brackets in this way, the electric wires are supported as much as possible so that the electric wires are unwound from the winding drum and do not interfere with the wound shutter curtain. The bracket is required to be fixed to the support bracket without protruding inward from the left and right inner side surfaces. Also, there are cases where the electric wire fixed to the support bracket is removed from the support bracket and fixed again during maintenance work, etc. In such a case, the electric wire should be removed and fixed so that it can be re-fixed easily. Is also required. Furthermore, there are some cases in which the left and right outer sides of the support bracket are covered with a decorative cover, and the decorative cover is difficult to remove. It is also required that the electric wire can be removed and re-fixed by itself.
Therefore, conventionally, a technique has been known in which a wiring fixture (clamp) is fastened to the left and right inner side surfaces of the support bracket with screws or the like, and the electric wire is fixed using the wiring fixture (for example, Patent Documents). 1). It is also proposed to process a cut and raised projecting in the left and right inward sides of the support bracket and fix the electric wire using the cut and raised.

Here, in the present embodiment, the electric wires 22 from the electric switch 4 to the control panel 19 are directed rearward and upward from the base end portion of the electric switch 4 supported by the bracket body 6a of the support bracket 6. After being pulled out, it is folded back toward the front upper part of the bracket body 6a, and further bent downwardly from here to the control panel 19 attached to the front lower part of the bracket body 6a. It is wired to reach. Then, the binding member locking holes 6h for fixing the electric wires 22 are provided at three convenient locations on the rear upper side of the electric switch 4, on the front upper side of the electric switch 4, and slightly above the control panel 19. In addition, the binding band is formed at three locations: a location immediately after being folded back toward the front, a location bent downward from the front upper portion of the bracket body 6a, and a location slightly above the control panel 19. The electric wire 22 is fixed by 23. In this case, the binding member locking hole 6h provided on the upper rear side of the electric switch 4 has a pair of locking grooves 6i facing the front-rear direction of the bracket body 6a and the communication groove 6j facing the vertical direction. The communication groove 6j is formed to be located on the rear side of the locking groove 6i. Further, the binding member locking holes 6h provided on the upper front side of the electric switch 4 are inclined so that the pair of locking grooves 6i are front-rear and rear-high, and the communication grooves 6j are front-rear and rear-low. The communication groove 6j is formed so as to be located on the rear side of the locking groove 6i. Further, the binding member locking hole 6h provided slightly above the control panel 19 has a pair of locking grooves 6i facing in the vertical direction, the communication grooves 6j facing in the front-rear direction, and the communication grooves 6j in the locking grooves 6i. It is formed so that it may be located on the upper side.
On the other hand, the electric wires 22 extending from the operation signal receiver 21 to the control panel 19 are wired so as to extend straight from the operation signal receiver 21 to the control panel 19. The binding member locking holes 6h for fixing the electric wires 22 are provided at three convenient locations on the front side, the front-rear direction intermediate portion, and the rear side of the lower portion of the bracket body 6a, and from the operation signal receiver 21. Three convenient points on the front side, the front-rear direction intermediate portion, and the rear side of the electric wire 22 reaching the control panel 19 are fixed by a binding band 23. In this case, the binding member locking hole 6h provided on the front side has a pair of locking grooves 6i facing the front-rear direction of the bracket body 6a, the communication groove 6j facing the vertical direction, and the communication groove 6j being the locking groove. It is formed so as to be located on the rear side of 6i. Further, the binding member locking hole 6h provided in the middle portion in the front-rear direction has a pair of locking grooves 6i facing the front-rear direction of the bracket body 6a, like the binding member locking hole 6h provided in the front side. The communication groove 6j is directed in the vertical direction, and the communication groove 6j is formed on the rear side of the locking groove 6i. Further, the binding member locking hole 6h provided on the rear side has a pair of locking grooves 6i facing the front-rear direction of the bracket body 6a, the communication groove 6j facing the vertical direction, and the communication groove 6j being the locking groove 6i. It is formed so that it may be located in the front side.
In this case, as is apparent from FIG. 3, the electric wire 22 drawn from the upper side of the base end of the electric switch 4 reaches the upper front side of the support bracket and is bent in a curved shape downward. What is wired so as to reach the lower front side of the support bracket is bound by the plurality of binding bands 23 in the range of the winding locus X in the shutter curtain 1 illustrated by a two-dot chain line.
In addition, by appropriately setting the location and direction in which the binding member locking hole 6h is provided in accordance with the arrangement direction, the length, and the like of the electric wire 22, the electric wire 22 can be reliably fixed. It is easy to perform the fixing work.

  Next, the details of the procedure for fixing the electric wire 22 will be described with reference to FIG. 5. First, the binding band 23 between the electric wire 22 arranged on the left and right inner side surfaces of the bracket body 6 a and the left and right inner side surfaces. Insert. Next, the middle part of the binding band 23 is inserted into the communication groove 6j of the binding member locking hole 6h, and is inserted into the communication groove 6j. As a result, the middle portion of the binding band 23 protrudes from the communication groove 6j to the left and right outer sides of the bracket body 6a. In this state, the binding band 23 is moved to the locking groove 6i side. Thereby, the binding band 23 is hung between the pair of locking grooves 6i in a state where the intermediate portion is positioned on the left and right outer sides of the bracket body 6a and the both ends are positioned on the left and right inner sides of the bracket body 6a. The And the said electric wire 22 is fixed to the right-and-left inner side surface of the bracket main body 6a by winding the said binding band 23 around the electric wire 22, and bundling it. In this manner, the electric wires 22 arranged on the left and right inner side surfaces of the bracket body 6a can be easily and reliably fixed only by work from the left and right inner sides of the bracket body 6a. When the electric wire 22 is removed from the left and right inner side surfaces of the bracket body 6a, the binding band 23 is cut or the binding band 23 can be removed by reversing the procedure described above if the binding band 23 is reusable. In any case, it can be easily removed from the left and right inner sides of the bracket body 6a.

  Further, a protrusion 6k that protrudes toward the outer periphery of the groove is formed on the inner periphery of the groove between the pair of locking grooves 6i and the communication groove 6j. The protrusion 6k can prevent the binding band 23 hung between the pair of locking grooves 6i from being shifted to the communication groove 6j side, thereby ensuring a more reliable electric wire. 22 is configured to be fixed.

  In this embodiment configured as described, the left and right support brackets 6 constituting the shutter case 2 are rotatably supported at both left and right ends of the winding drum 3 around which the shutter curtain 1 is wound. In the cylinder of the winding drum 3, an electric switch 4 that drives the winding drum 3 to rotate forward and backward is housed, and the electric wires 22 reaching the electric switch 4 are connected to the left and right inner side surfaces of the support bracket 6. Wiring is performed along Further, the wired electric wire 22 is unwound from the winding drum 3 and is fixed to the left and right inner side surfaces of the support bracket 6 so as not to interfere with the wound shutter curtain 1. In addition, the support bracket 6 is provided with a binding member locking hole 6h including a pair of locking grooves 6i facing each other and a communication groove 6j that communicates one end portions of the pair of locking grooves 6i. Yes. Then, an intermediate portion of the binding band 23 is inserted into the communication groove 6j of the binding member locking hole 6h from the left and right inner sides of the support bracket 6, and the binding band 23 is moved to the locking groove 6i side. The binding band 23 is looped between the locking grooves 6i, and the electric wire 22 is supported by binding the electric wires 22 arranged on the left and right inner side surfaces of the support bracket 6 with the wound binding band 23. The bracket 6 is fixed to the right and left inner side surfaces.

  As described above, in the embodiment in which the present invention is implemented, when the electric wires 22 arranged along the left and right inner side surfaces of the support bracket 6 are fixed to the left and right inner side surfaces, the binding holes drilled in the support bracket 6 are provided. The electric wire 22 can be fixed by a simple operation in which the binding band 23 is hung around the member locking hole 6h from the left and right inner sides of the support bracket 6 and the electric wire 22 is bound by the binding band 23. As a result, the electric wire 22 can be fixed efficiently, and the electric wire 22 can be removed only from the left and right inner sides of the support bracket 6, that is, the inner side of the shutter case 2, during maintenance. In such a case, it is difficult to remove the decorative cover 13 that covers the left and right outer sides of the support bracket 6 due to the state of the shutter case 2 being housed in the housing. Even if it exists, this makeup | decoration cover 13 can remove the electric wire 22 easily in the state as it is, and can perform re-fixing work.

  In addition, since the binding member locking holes 6h drilled in the support bracket 6 can be punched by a press such as a turret punch press, a dedicated processing is performed as in the case of forming a cut-and-raised portion for fixing an electric wire. It does not require a mold and can greatly contribute to cost reduction. In addition, since the electric wires 22 are bound by the binding band 23 wound around the support bracket 6 in the perforated binding member locking holes 6h, the support bracket 6 should not protrude from the left and right inner surfaces as much as possible. The electric wire 22 can be fixed to the left and right inner surfaces.

  Further, in this case, the binding band 23 hung between the pair of locking grooves 6i is displaced toward the communication groove 6j on the inner periphery of the groove between the locking groove 6i and the communication groove 6j. A protrusion 6k is provided to prevent this. As a result, it is possible to reliably avoid the binding band 23 from being displaced to the communication groove 6j side and coming out of the binding member locking hole 6h, so that the electric wire 22 can be securely fixed.

  Of course, the present invention is not limited to the above embodiment. For example, the binding member locking hole drilled in the support bracket is formed in a U shape in the above embodiment. As shown in FIG. 6 (B), a connecting groove 24b that connects one end portions of the pair of locking grooves 24a is formed in a semicircular shape, as shown in FIG. 6 (B). , (D) like the binding member locking holes 25, 26, the communication grooves 25 b, 26 b that communicate with one end of the pair of locking grooves 25 a, 26 a may be formed in a semi-polygon shape. good. In FIGS. 6B, 6C, and 6D, 24c, 25c, and 26c are protrusions for preventing the binding member from being displaced toward the communication grooves 24b, 25b, and 26b. Further, as in the binding member locking hole 27 shown in FIG. 6 (E), it may be formed in a C shape by the locking groove 27a and the communication groove 27b. By forming the locking hole 27 in a C shape, the binding member is prevented from shifting to the communication groove 27b side on the inner circumferential side of the groove between the locking groove 27a and the communication groove 27b. A protrusion 27c is formed.

  Further, in the above embodiment, the electric wire is fixed to the left support bracket, but the present invention is similarly implemented even if the electric wire is fixed to the right support bracket. Of course you can. Furthermore, in the above embodiment, the power supply and operation signal wires connected from the operation signal receiver to the control unit, and the wires extending from the control unit to the electric switch are fixed to the left and right inner surfaces of the support bracket.
