JPS5829709Y2 - Attachment with push-lock alarm and chime switch - Google Patents

Description

[Detailed description of the invention] This invention is a button-type lock for an entrance door in which the handle is unlocked by pushing the push button downward, and then the handle is pulled to open the door. , an operating plate is attached to the extension shaft connected to the push button, and the protruding piece on the upper part of the operating plate presses the control piece of the switch fixed to the pedestal, and the switch is connected to the switch. Regarding alarms and chime emitting switch attachments with pushbutton locks that operate the alarm or chime by closing the electric circuit to the alarm or chime, improvements to existing or commercially available pushbutton locks may be made. is designed so that even amateurs can easily install it without any modification.

An example of the implementation of the combined invention will be explained in detail with reference to a diagram.
A push button 2 provided above the handle 1 is provided with an extension shaft 3, and a hole 5 into which the extension shaft 3 of a button lock 4 can be fitted loosely is provided, and a switch to switch between an alarm A and a chime C. A pedestal 8 is formed on which a microswitch 7 communicating via 6 is installed.

Then, an operating plate 11 is formed by providing a hole 9 through which the extension shaft 3 is fixed and a protrusion 10 on the upper side, and the extension shaft 3 is fixed through the hole 9 to operate the operating shaft 3. It is integrally connected and fixed to a plate 11, and the actuating plate 11 is moved upward by pressing the push button 2, and the control piece 12 of the micro switch 7 is pressed by the protruding piece 10 on the upper end of the actuating plate 11, and the alarm A or chime is activated. Close the electrical circuit to C and activate alarm A or chime C.

When the push button 2 is released, the actuating plate 11 moves downward, and the pressing state of the control piece 12 of the microswitch 7 by the protruding piece 10 on the upper end of the actuating plate 11 is released, and the alarm A
Alternatively, the electric circuit to chime C is released, and the operation of alarm A or chime C is stopped.

Note that 15 in the figure is an insulating plate.

FIG. 3 is a typical circuit diagram in which alarm A and chime C are connected to the attachment of the present invention, and both alarm A and chime C can be deactivated by turning off the main switch SW1. Main switch SW1
Either the alarm A or the chime C can be used as desired by turning on the alarm and switching the selector switch 6 appropriately.

4 shows another embodiment, in which a reed switch 13 is used instead of the microswitch 7, and a magnet 14 is installed on the protrusion 10, so that the actuating plate 11 can be moved up and down. The reed switch 13 is opened and closed by moving the magnet 14 up and down, and its operation is exactly the same as that of the microswitch 7.

Since the present invention is as described above, the microswitch 7, the pedestal 8 having the hole 5, and the actuating plate 11 having the hole 9 and the protruding piece 10 are formed as attachments, making it extremely easy to use even for an amateur. It can be attached to a lock, there is no need to modify or process the lock, and the use of alarm A and chime C can be arbitrarily selected using the changeover switch 6. Moreover, the structure is simple, so there is no failure after installation. There are great benefits to this.

In addition, conventional alarm locks have a reed switch or microswitch installed near the latch inside the lock.
Although the alarm and chime are activated by pressing the handle on the indoor side, it is unnecessary and meaningless to activate the handle by pressing the handle on the indoor side.

However, by attaching the inventive attachment to the handle 1 on the indoor side, depending on the lock, the handles on the indoor and outdoor sides will operate separately, so the alarm will only occur when push button 2 of the handle 1 on the outdoor side is pressed. Instrument A or chime C operates, and its effect is extremely reliable.

It goes without saying that the attachment of the present invention can also be used by being pre-assembled into a bushing type lock.

[Brief explanation of the drawing]

The figures show an example of the implementation of the present invention, in which Fig. 1 is a partially cutaway side view, Fig. 2 is a front view of the pedestal and actuating plate, Fig. 3 is a circuit diagram, and Fig. 4 is another embodiment. It is a front view of a pedestal and an actuation plate showing an example. 2 is a push button, 3 is an extension shaft, 4 is a button type lock, 5 is a hole, 6 is a selector switch, 7 is a micro switch, 8 is a pedestal, 9 is a hole, 10 is a protrusion, 11 is an operating plate, 13 is a Reed switch, 14 is a magnet, A is an alarm, and C is a chime.

Claims (1)
