[Industrial application field]

This invention is a manual interlocking device for opening and closing connected shutters in aluminum sashes. Regarding.

0002

[Conventional technology]

The conventional technology for interlocking the opening and closing of connected shutters in aluminum sashes is based on motors. It was an electric device.

0003

[Problem that the idea aims to solve]

According to such electrically operated interlocking switchgear, the device becomes large and the power supply is required. There are issues that require it.

0004

[Means to solve the problem]

Therefore, the present invention has developed a wire that connects a drum connected to an operating section located near the indoor door pocket. The wire was wound around the drum, and both ends of the wire were led out from the drum and movably mounted on the upper frame. Connect both ends of this wire to the actuating body, slidably fit the connecting rod into the locking tube, and then The connecting body, which is always biased towards the above-mentioned operating body by the ring, is attached to the first shutter of the connected shutters. After installation, check that the connecting rod is locked to the actuating body by the elastic force of the spring. Features.

[0005]

[Effect]

According to the above configuration, by operating the operation unit and rotating the drum, the The actuating body can be moved along the upper frame via the Move the leading shutter of the connected shutter through the link, thereby opening the entire connected shutter. The actuating body and the connecting body are connected by the connecting rod of the connecting body. The tip is locked to the actuating body by the elastic force of the spring. The connecting body can be locked to the actuating body at all times, and the connecting shutter and the actuating body are connected as one unit. This means that the connected shutters can be opened and closed.

【Example】

An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a side view showing the state of the actuating body and the connecting body, Fig. 2 is a plan view of the actuating body, and Fig. 3 is an open view of the actuating body. FIG. 4 is a plan view of the closing device, FIG. 4 is a side view, and FIG. 5 is an overall schematic front view. In the figure, 1 are connecting shutters, which are interconnected by connectors. 2 is an operating unit attached near the indoor door of the frame 3, and a handle is also attached to the rotating shaft 4. A rotating body 6 is attached which is rotated and operated by an operating part 5 such as an operating chain. , a gear 7 is further attached to this rotating shaft 4. A gear 8 pivotally supported by the operating section 2 meshes with the gear 7. There is a rotating shaft at the center, and a drum 9 is attached to this rotating shaft. to this drum 9 has a wire 10 wound around it, and both ends of this wire 10 are led out from the drum 9. has been done. 11 is an actuating body movably attached to the upper frame 3a, and is connected to both sides of the wire 10. The ends are connected. 12 is a connecting body attached to the top of the leading shutter of the connecting shutter 1, as shown in Figure 1. As shown, a connecting rod 12b is slidably fitted into the locking tube 12a, and is locked into the locking tube 12a. There is a guide groove 12d having a portion 12c, into which a protrusion 12e protruding from the connecting rod 12b is fitted. The connecting rod 12b can now slide within the range of this guide groove 12d. ing. Further, a spring 12f is installed between the locking cylinder 12a and the connecting rod 12b. The tip of the connecting rod 12b is always biased in the direction of protruding from the locking tube 12a. ing. Further, the actuating body 11 has a locking portion on which the tip of the connecting rod 12b of the connecting body 12 locks. 11a is formed. Therefore, under normal conditions, the tip of the connecting rod 12b is locked to the locking portion 11a of the actuating body 11. As a result, the operating body 11 and the leading shutter of the connecting shutter 1 are connected. ing. Therefore, if you want to release this connected state, pinch the protrusion 12e and connect it. The rod 12b is moved along the guide groove 12d against the elastic force of the spring 12f. By this, the actuating body 11 is released from the locking part 11a, and the protrusion 12e is moved into the guide groove 12d. The released state can be maintained by being locked to the locking portion 12c of . Note that both ends of the wire 10 are guided to the operating body 11 by pulleys. For example, if you turn the operating part 5 clockwise (counterclockwise), the shutter will close and turn the shutter counterclockwise. By turning it clockwise, you can open the shutters.

[0007] According to the above configuration, when the operating section 5 is turned clockwise (counterclockwise), one end of the The wire 10 is pulled and wound onto the drum 9, and the wire 10 at the other end is unloaded from the drum 9. The operating body 11 moves along the upper frame 3a, and the leading shutter of the connected shutter is pulled out. The shutters can then be pulled out from the door pocket one after another and the shutters can be closed. Next, when the operating unit 5 is turned counterclockwise (clockwise), the wire 10 at one end is pulled. The wire 10 at the other end is unwound from the drum 9. The operating body 11 moves along the upper frame 3a, and the leading shutter of the connected shutter is pulled toward the door pocket. You can open the shutter by pressing the entire connected shutter and storing it in the door pocket one by one. can. Note that, if necessary, the connecting body 12 can be removed from the actuating body 11 to release the connected state. The shutters can be opened and closed manually.

[0008]

[Effect of the idea]

According to the present invention explained in detail above, the Wrap the wire around the drum, lead both ends of the wire out of the drum, and attach it to the upper frame. Connect both ends of this wire to a movable actuator, and slide the connecting rod into the locking tube. A connecting body that is movably fitted and constantly biased toward the above-mentioned operating body by a spring is connected. Attach it to the top of the shutter, and use the elastic force of the spring to connect the connecting body to the above-mentioned operating body. By locking, the actuating body can be rotated by operating the operating section and rotating the drum. It can be moved along the upper frame, and this movement allows the connected shutters to be connected via the connecting body. By moving the leading shutter, you can open and close the entire connected shutter. This allows the operator to open and close the connected shutters at will by simply operating the control unit indoors. It has the effect of being able to. In addition, if an unexpected situation arises and you want to remove the storm door, the operator must hold the connecting rod of the connecting body in place. The connection with the actuating body can be easily released by sliding it with the guide of the stop tube. This means that the shutters can be removed in an emergency.
