Abstract

PURPOSE:To provide an engaging device with separation alarming means being simple in structure and easy for opration, by a method wherein the engaging device is composed of a pair of engaging members utilizing a permanent magnet and a ferromagnetic body, and a lead switch to be energized and closed is installed to lateral side of the attaching engaging member. CONSTITUTION:A ferromagnetic plate 2 is attached to one pole surface of a permanent magnet 1 and covered integrally by a non-magnetic case 5, and a washer 6 having a leg 6(a) is attached to the plate 2 by a ferromagnetic lever 2(a). In a male engaging member also a washer 6 is attached to a ferromagnetic plate 3 by a ferromagnetic lever 3(a). A lead switch 4 installed to lateral side of engaging portion is not at all subjected to magnetic line of force in the engaging state. When the plate 3 and the magnet 1 are separated from each other, magnetic line of force comes out of the engaging device thereby the lead switch 4 is energized for alarming. When the engaging device is used to opening surface as engaging means of a cover of a handbag or a fancy case, it is effective as a device being small in the number of parts and simple in operation without failure.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention closes the operating circuit of a suitable alarm device such as a buzzer or an alarm lamp by opening the container or other opening, and generates a predetermined signal at the same time as the container is opened. This is related to the disclosure of an engaging structure that effectively prevents containers from falling or being stolen.Therefore, in the past, the means for notifying the open state of containers of this kind Various attempts have been made to improve the open state of the lid for small containers such as wallets and handbags, or for containers that do not have a specific structure, such as those made of fabric or leather. It is extremely time-consuming to detect and issue an alarm accurately, and the device itself is complicated, making the production cost relatively high.

The engagement tool of the present invention ensures detection of the open state of a container by continuously detecting the open state of such conventional containers and immediately activating an alarm when the engagement tool itself opens and closes. simplification of the structure by using the engaging tool itself as a means for opening and closing the operating circuit in these alarm means;
This is intended to simplify handling, and the gist of its configuration is a permanent magnet (1) with a hole 11) 1 opened from one pole face to the other pole face, with a strong attachment firmly attached to the magnetic pole face. A magnetic plate (2) and a ferromagnetic plate 13) which is in contact with the other magnetic pole face in a removably magnetic manner.

The ferromagnetic base 12+'a, 131a protruding from either or both of the chain plates 121 and (3) is inserted into the hole (1)a.
Through the other plate (2)% 131 or rod 121 a,
131 An alarm circuit in which a pair of engaging tools, which are magnetically attached and removably brought into contact with the ends a, are attached oppositely to the opening of a container, etc., and the attachment is closed by excitation from the side of the engaging tools. It was placed at a point where a reed switch was installed. Furthermore, the following specific embodiments of the engaging tool according to the present invention are based on the above-mentioned configuration and gist, and considerable design changes are planned for Cζ.

A typical embodiment of the engaging device according to the present invention will be described below with reference to the accompanying drawings. Reference numeral 14) is a reed switch that is energized and closed, and is an alarm buzzer that is usually used as an alarm means.

The assembly is used in lamps and other operating circuits. Note that a manual open/close switch with the same number as this reed switch (4) is usually assembled into the operating circuit separately, so that the buzzer activation, etc. that occurs when the reed switch (4) is closed is performed when the reed switch (1) is closed. The reed switch 1 is installed in the circuit so that it can be stopped at any time.
4) It should be installed on one side of the engaging tool used to open and close the container opening part, especially at the bottom of the magnet, and the opening and closing of the magnetic circuit accompanying the opening and closing of the engaging tool will cause the switch to open and close. 14)
It is designed to regulate the operation of the

The engaging tool that has this purpose is a bar steel magnet.

Holes Ill 11 are formed across the magnetic pole surface direction of various magnets 11) such as sintered magnets, plastic magnets, and rare earth magnets.
The ferromagnetic plate 12) is attached to one of the a-pole surfaces of the ferromagnetic plate 12), and a ferromagnetic plate 13) of male+IjL7 is attached to the other 11-pole surface in a removable manner. and 13
Ferromagnetic beams 121a, 131a' protruding from 1
A magnetically attached and removable abutment is made in the hole a for the t hole 7
:: is also C.

In such an engaging tool, when the lid of the container is closed and both engaging tools are properly attached, the lines of magnetic force in the magnet +1+ will pass through plate (2), rod 12) a% 13 + a% plate 13) →It constitutes a talk line, creates a so-called magnetic closed circuit state, and completely eliminates the action of magnetic lines of force on the lead pin 14).

Therefore, the lead pin (4) is deenergized and functions to open the alarm circuit.

Next, when the opening of the container is removed, the plate 3 of the engaging tool is
1 is pulled away from the magnet 11), the previous magnetic closed circuit is released, and the lines of magnetic force jump out of the engaging tool, fully energizing the reed switch (4) and making it act as a closing metal for the alarm circuit. 0 Hawk Figures 2 to 9 The embodiments shown here are examples of these engaging tools, and include a case (51) made of a non-magnetic material with a magnet 11 and a plate (2). The rod (2) and the leg (613% (washer 16 with 61a) are integrally connected to the plate (2), and the male stopper is also attached. Similarly, for plate !: 11, the washer (6) @ +31 B was attached properly with the oak I attachment, and it is a r thing.

Incidentally, the embodiment shown in FIG. 3 has a weight of +31 g?
The upper surface of IP hole + t + a is exposed! i! His father, who probably bent the periphery of plate 13) and made it IIIk tsuba (31b), which belonged to Mr. 1.
In the embodiment shown in the figure, the rod 131a is directly connected to the hole '1)a, and the rod 12)a is completely omitted.

Next, @iil! shown in Figures 5 to 7! The travel example uses a funnel-shaped tube (7) 8% + 71b, t instead of the washer (6).
An example is shown using 71cf, and further @8 figure and 9
The figure shows the thin part of (2)a%(3)a in the form of a pin or screw for direct attachment to the opening of the chamber.

It should be noted that various methods are envisaged for attaching these engagement tools, and in any of these methods, the engagement tools can be used for the desired lead pin operation.

Furthermore, in the case of the reed switch 14) mounting IC, the reed switch 14 is mounted on the magnet (1) used in the engagement tool (as shown in this diagram). Special consideration has been given to avoid protruding further, and this type of engagement means: female and male fittings are provided on each opening surface as means for attaching the lids of handbags, wallets, and small containers. A reed switch (4) for opening/closing the alarm handrail is installed on the side of this engaging tool, which is attached oppositely and used for engaging or releasing the cover plate, etc. The unexpected opening of the container was intended to alert the Emperor.

By assembling the alarm means, it will effectively prevent the accidental opening of the handbag lid, especially the contents falling off due to forgetting to close it, or falling off due to impact: No. 1 It was also particularly effective as an anti-theft IF.

In addition, the number of parts is reduced because all the engaging members of the lid itself are used directly, and there is no need to assemble the special 6 operation structure, which makes the operation simpler and eliminates malfunctions, while reducing manufacturing costs. This was achieved at a relatively low price.
