[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned conventional problems and to provide a method of locking a hinged door having a simple structure in an earthquake and a method of detecting an earthquake in a hinged door locking device.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a vibrating body provided on a main body side capable of swinging in both directions from a stable position thereof, wherein the vibrating body itself is a locking member for an opening door. The present invention proposes a method for locking a hinged door that locks and locks during an earthquake.

Hereinafter, a method of locking a hinged door having a simple structure according to the present invention in an earthquake and a method of detecting an earthquake in a hinged door locking device will be described with reference to the embodiments shown in the drawings. The following description of the embodiment is based on the description of the case of a hinged door, but it describes the method of locking the hinged door in the event of an earthquake and the method of detecting an earthquake in the hinged door lock device itself. 1 and 2 show an object locking device for detecting vibrations used for a hinged door according to the present invention, which is attached to one end of a spring means (1) (shown in the form of a leaf spring). It has a magnet (2). The other end of the spring means (1) is attached to the main body (91) by fixing means (92) such as a screw. As an example of the mounting method of the magnet (2), in the illustrated example, a bush (3) is fitted and fixed in a hole of the magnet (2), and a screw serving as a projection (8) is screwed into a female screw of the bush (3). The one attached with is shown. The screw as the protruding body (8) protrudes below the magnet (2), and serves as a locking means (5) for a main body side bracket (4) made of a magnetic material (material attached to the magnet) such as steel. It is positioned above the hole. Next, below the locking means (5), a hole (greater than the hole of the body-side metal fitting (4)) serving as the locking means (7) of the object-side metal fitting (6) fixed to the main body (91). (Which absorbs misalignment). The operation of the hinged door of the present invention shown in the above embodiment during an earthquake is as follows. That is, in the state of no vibration, the screw as the protruding body (8) is a magnet (2).
At the same time, it is separated from the main body side fitting (4) by the spring means (1) above the main body side fitting (4). The hole serving as the locking means (7) of the object side fitting (6) is located below the hole serving as the locking means (5) of the main body side fitting (4).
Therefore, in the state of non-vibration, the object side bracket (6) can move in the direction of the movement of the arrow shown in the figure without any obstacle. Next, when a vibration such as an earthquake occurs, the spring means (1) starts to vibrate, and if the shaking is large, the vibration increases. When the amplitude exceeds a certain level, the magnet (2) is attracted to the metal fitting (4) (the vibration is terminated by the attraction). As a result, the screw serving as the protruding body (8) penetrates the locking means (5) of the metal fitting (4) and the locking means (7) of the metal fitting (6) as shown in FIG. Becomes Since the state of the protruding body (8) is held by the magnet (2), vibration can be detected, and for example, a switch or the like can be operated or used for optical detection. Further, the one shown in the figure performs not only the detection of vibration but also the locking of an object.
Abuts against both the locking means (5) and the locking means (7) and receives shearing force in the direction of the movement path. The shear force is defined as a force F in which the object-side metal fitting (6) pushes the protrusion (8) to the left in FIG. 2 and a main body-side metal fitting (4) moves the protrusion (8) to the right in FIG. The pushing force G is the shearing force of both. Since the shearing forces F and G are slightly shifted in the vertical direction, the projecting body (8) receives a moment.

This moment is generated at the point where the left edge of the hole as the locking means (5) of the body side bracket (4) in FIG. 2 and the thread of the screw as the protruding body (8) are caught. Of the magnet (2) and the force J of the body-side fitting (4) pressing the lower right end of the lower surface of the magnet (2) upward. That is, the locking means (7) of the object side metal fitting (6) is locked by the locking means (5) of the main body side metal fitting (4) via the screw (8). The above embodiment is an example, and another embodiment of the present invention will be described below. FIG.
1 shows another device used for the hinged door of the present invention, which is different from those shown in FIGS. 1 and 2 in the direction of the movement path (the arrow shown) of the object side bracket (6). Regarding the direction of this movement path, if the spring means (1) is a leaf spring, the protruding body (8) can be inclined more easily when a shearing force is generated in a direction perpendicular to the direction of the leaf spring (FIGS. 1 and 2). However, since this is not an essential problem, not only the vibration detection but also the object locking can be performed in the apparatus shown in FIG. FIG. 4 shows another apparatus used for the hinged door according to the present invention. This apparatus is different from the above-mentioned embodiment in that the locking means (5) of the metal fitting (4) is not a hole but a groove and a spring means. (1) is characterized in that it vibrates up and down from below. FIG. 5 shows another apparatus used for the hinged door according to the present invention, which is characterized in that the magnet (2) and the projecting body (8) are separated as compared with the above embodiment.
The magnet (2) is fixed to the spring means (1) by, for example, a dowel (12), and the screw as the projection (8) is fixed to the spring means by a nut (10). The direction of vibration of the spring means (1) is horizontal. FIG. 6 shows another apparatus used for the hinged door according to the present invention. This apparatus uses a rotary holder (5a) as well as a hole as a locking means (5) of the main body side bracket (4). That is, the shearing force G is borne by the hole, and the moment is supported by the force H which pushes the upper end face of the magnet (2) downward by the rotary presser (5a), which is a bent piece of the main body side bracket (4). For this reason, the protruding body (8) is closely fitted directly to the magnet (2) as shown, for example, without using a screw (which may be considered as a protruding body having flared teeth on the side). You may use something like a dowel without teeth on the side. FIG. 7 shows another device used for the hinged door according to the present invention. This device has a main body side fitting (4), but the magnet (2) is configured to be directly attracted to the object side fitting (6). I have. Therefore, the object side bracket (6) must be made of a magnetic material.
The main body side bracket (4) has a tension presser (5b) that bears a shearing force G and a rotary presser (5a) that bears a downward pushing force H that supports a moment. Further, the magnet (2) shown in FIG. 7 is protected by a magnetic back plate (8a), and a screw as a projecting body (8) is screwed into a female thread of the back plate (8a). Is sandwiched between the spring means (1) and the back plate (8a). Since the back plate (8a) is a magnetic substance and is magnetized, the back plate (8a) should be considered as a part of the magnet (2) magnetically. The configuration shown in FIG. 7 is suitable when it is not desired to apply a large force to the magnet (2), while the configuration shown in FIG. 6 may be used when a relatively small force is locked and the magnet (2) is not overloaded.

FIG. 8 shows another apparatus used for the hinged door of the present invention, which is an embodiment of FIGS. 1 to 7 in which a magnet (2) and a projection (8) are attached to a spring means (1). Unlike the example, the spring means (1) is characterized in that a magnetic plate (11) and a protruding body (8) are attached. That is, when the magnet (2) is brought into close contact with the metal fitting (4) (magnetic material) on the main body side and magnetically becomes a part of the magnet (2), when the vibration of the spring means (1) exceeds a predetermined level, the magnetic material plate (11) is formed. ) Is a magnet (2)
It is adsorbed to the main body side fitting (4). FIG. 9 shows another apparatus used for the hinged door of the present invention, which is shown in FIG.
Similarly, the magnetic plate (11) and the protruding body (8) are attached to the spring means (1), and the magnet (2) faces the lower part of the magnetic plate (11) and the main body side fitting (4). ) Is attached by gluing (a large force is not applied to the magnet itself). FIG. 10 shows another device used for the hinged door according to the present invention, in which the spring means (1) is made of a magnetic material such as a steel plate and the spring means (1) itself is used as a magnetic material. Therefore, the screw as the protruding body (8) is attached to the spring means (1) with the nut (10), and when the vibration of the spring means (1) exceeds a predetermined level, the spring means (1) itself is attracted to the magnet (2). It is. FIGS. 11 and 12 show another device used for the hinged door of the present invention, in which the spring means (1) is constituted by a coil spring instead of a leaf spring. The locking mechanism (refer to the forces F, G, H and J) when used as an object locking device is the same as that shown in FIG. FIG. 13 shows another apparatus used for the hinged door of the present invention. This apparatus is the same as that shown in FIGS. 11 and 12 in that a coil spring is used as the spring means (1), but the locking mechanism is different. That is, the force F for pushing the protruding body (8) to the right in FIG. 13 when the object side metal fitting (6) is about to move is such that the main body side metal fitting (4) moves the protruding body (8) to the left in FIG. It tries to balance as the shearing force with the force G that pushes toward the direction. The moment generated due to the displacement of the shearing forces F and G in the vertical direction is such that the side wall of the projection (8) and the cylinder (20) accommodating the magnet (2) is formed by the projection (8).
Are balanced by a force K that pushes the lower end of FIG. 13 rightward in FIG. That is, such a locking mechanism is achieved by the movement of the protruding body (8) being restricted by the movement of the vertical vibration by the cylinder (20). FIG. 14 omits the main body side fitting (4) of FIG. 13 and directly attracts the magnet (2) to the magnetic object side fitting (6), and bears the shearing force G by the side wall of the cylinder (20). It is. By specifying the "object" in the above description of FIGS. 1 to 14 as "swing door", the explanation of the swing door which is locked in the event of an earthquake of the present invention is provided, and is sufficient as the description of the present invention. A more specific embodiment will be described below. First, Figure 1
5 is a main body (9) near the upper end face of the hinged door (61) (62).
1) A spring means (1) of a leaf spring incorporated in a main body fitting (30) is attached to a (supporting body of a hinged door) (for example, the main body of furniture). At both ends of the spring means (1), a magnet (2) and screws as projections (8) similar to those in FIGS. 1 and 2 are attached.

Both ends of the horizontal portion of the main body fitting (30) are used as main body side fittings (4). That is, holes as locking means (5) are provided at both ends, and the rods (8) at both ends of the spring means (1) can be fitted. On the other hand, an object side metal fitting (6) is fixed to the upper end surface of the hinged door (61) (62) with a screw or the like facing below a hole as a locking means (5) of the main body metal fitting (30). In a state without vibration, the protruding body (8) floats away from the object-side bracket (6), and the hinged doors (61) and (62) can be freely opened and closed. Next, when an earthquake occurs, the spring means (1) vibrates and when the amplitude becomes a certain level or more, the magnet (2) is attracted to the main body fitting (30) as the main body side fitting (4). As a result, the protruding body (8) is fitted into the hole as the locking means (7) of the object-side bracket (6). As a result, the hinged doors (61) and (62) are locked by the locking mechanism shown in FIG. 2 without being opened even if they are opened by an earthquake, and thus the stored doors (61) and (62) are not released from the opened hinged doors (61) and (62). It is.
Next, FIG. 16 is the same as the hinged door which is locked in the event of an earthquake, but inside (FIG. 16) instead of outside (FIG. 15) the hinged door.
And a locking device. That is, the hinged doors (61) and (62) are closed by the magnet (44) of the magnet catch (40) (the closed state is maintained).
The magnet catch (40) itself is conventionally known, but the magnet (44) of the magnet catch (40) is used.
A hinged door which is locked in the event of an earthquake is incorporated into the side of the holding body (42) (the protruding position of which is adjusted by turning a screw (45) to which the teeth on the outer side are coupled). That is, the holder (42) is substantially L-shaped by the screw (49).
A main body side bracket (4) extending downward in a letter shape is fixed.
Further, a spring support (4) extending rearward with the same screw (49) is used.
3) is fixed, and the rear end of the spring means (1) is fixed to the rear end. The spring means (1) extends forward and has a magnet (2) and a screw (8) similar to those shown in FIGS. 1 and 2 attached to its front end. The protruding body (8) is positioned so that it can be fitted into a hole serving as a locking means (5) of the main body side fitting (4). On the other hand, the object side bracket (6) is fixed to the back of the hinged door (61), and the one shown is the magnet (4) of the magnet catch (40).
4) also serves as an adsorbent. That is, the closed state of the hinged doors (61) and (62) by the magnet catch (40) is performed by the object-side fitting (6) being attracted to the magnet (44). In a state without vibration, the protruding body (8) floats away from the object-side bracket (6), and the hinged doors (61) and (62) can be freely opened and closed.
Next, when an earthquake occurs, the spring means (1) vibrates and when the amplitude exceeds a certain level, the magnet (2) is attracted to the main body side fitting (4). As a result, the projecting body (8) becomes the object-side bracket (6).
And is locked in the hole as the locking means (7). As a result, the hinged doors (61) and (62) cannot withstand the earthquake due to the attraction force of the magnet (44) of the magnet catch (40), and will not be opened by the lock of the protruding body (8) even if they are opened. Holder (42) for supporting a force such as bending or twisting of holder (42) of magnet (44)
Is fitted to the rail (46) to strengthen the connection with the main body (41). As shown in FIG. 16, the advantage of incorporating the magnet (44) of the magnet catch (40) into the holder (42) itself is that the positional relationship between the hinged doors (61) and (62) and the magnet (44) is constant (the hinged doors (61) and (62)). ) And the front end of the magnet (44) have a fixed positional relationship)
It is to be. This means that the position of the locking means (5) of the metal fitting (4) and the locking means (7) of the object-side metal fitting (6) does not shift, and the locking of the protruding body (8) is ensured. become.

As shown in FIG. 16, the hinged door (61) (6)
In the case where the lock device is incorporated in 2), a method of releasing the lock when locked is required. In the illustrated embodiment, the operating piece (51) of the L-shaped release fitting (50) made of a thin (eg, about 0.2 mm) leaf spring material is opened to open the door (61).
It is exposed to the outside along the front surface of the main body (91) through a gap between the main body (91) and the space (62). The other end of the L shape of the release fitting (50) is attached as a spring piece (52) to the main body (41) of the magnet catch (40), for example, with a screw or the like.
That is, when the operating piece (51) is pressed, the release fitting (50) can sink downward by the spring characteristic of the spring piece (52). A release piece (53) bent downward is provided on one side of the release piece (50) near the tip of the spring piece (52), and when the operating piece (51) is pushed down and lowered, this is spring means (1).
Abuts on the end piece (1a) of the tip of. Release piece (5
The action of pressing the end piece (1a) of the spring means (1) with the inclined edge of (3) or the spring piece (52) is twisted (partially cutout is effective as shown in the figure due to the twist of the spring piece (52)). The magnet (2) attracted by the release piece (53) rotating in the direction of separating the end piece (1a) and causing the end piece (1a) to separate directly.
Is physically separated from the main body side fitting (4) and released.
The vibration detecting spring means (1) used in the vibration (including earthquake) detecting device in FIG. 16 is a magnet catch (40).
17 is used for the vibration (including earthquake) detecting device (9) at the position shown in FIG. A, b in FIG. 17 (b in FIG. 16)
) Or c indicates a position at which the object-side bracket (6) is selected. The position of d in FIG. 18 is the same as the position at which the object side bracket (6) of FIG. 17 is selected. In any case, FIGS. 17 and 18 show the vibration detecting spring (1) of the vibration (including earthquake) detecting device (9) attached to the holder (42) of the magnet (44). It was a magnet catch with means (40). 19 and 20 show a vibration detecting spring means (1) of a vibration (including earthquake) detecting device (9).
Is a magnet catch (40) with a vibration detecting spring means attached to the main body (41) of the magnet catch (40). E, f, g in FIGS. 19 and 20
Or, h indicates a position at which the object side bracket (6) is selected. Next, FIG. 21 shows a magnet catch with a vibration detecting spring means (1) of the vibration (including earthquake) detecting device (9) attached to the main body (41) of the magnet catch (40) itself. (40)
(J or k is the position of the object side bracket (6)) as in FIGS. 19 and 20, but the structure of the magnet catch (40) is different and the magnet catch (40) having the structure shown in FIG. ). That is, it clarifies that the structure of the magnet catch (40) itself may be variously selected. 22 and 23 show that the vibration detecting spring means (1) of the vibration (including earthquake) detecting device (9) is attached to the holder (42) of the magnet (44) of the magnet catch (40) of FIG. A magnet catch (40) with a spring means for detecting vibration.
In FIGS. 22 and 23, p, q, r, or s indicates a position at which the object-side bracket (6) is selected. Next, the vibration (including earthquake) detecting device (9) and the vibration detecting spring means (1) are not limited to those shown in FIG. Further, the following is merely an example of the vibration (including earthquake) detecting device (9) and the vibration detecting spring means (1), and it is necessary that the vibration detecting spring means (1) be provided. Spring means for detecting the vibration (1)
It is clarified here again that the structure of, how to use the vibration, and how to take out the output are irrelevant.

FIGS. 24 and 25 show a pendulum for detecting vibration as a vibrating body of a hinged door according to the present invention, and the pendulum for detecting vibration is a spring means (1) for detecting vibration shown in FIGS.
(However, it goes without saying that it involves a slight design change). Magnet (4) as shown
The pendulum (72) is attached to the holder (42) of 4) so as to be able to vibrate by the shaft (73). However, it is attached to the holder (42) not directly but via a mounting plate (71) so as to be able to vibrate indirectly. A magnet (2) is attached to the lower surface of the pendulum (72) by bonding or the like, and when the pendulum (72) vibrates and its amplitude exceeds a certain level, the same main body side bracket (4) as shown in FIG. Can be adsorbed. Pendulum (7
When 2) is attracted to the metal fitting (4) on the main body side, the protrusion (8)
Is fitted into a groove serving as a locking means (7) of the object-side bracket (6), and is locked. As a result, the hinged door (62) cannot be opened by the locking of the protruding body (8).
This is the same as the description of the third vibration detecting spring means (1). The various embodiments of the vibration detecting spring means (1) shown in FIGS. 1 to 23 are applicable to all the pendulums (72), and the respective embodiments will not be described again. FIG. 26 shows another swing door which is locked in the event of an earthquake according to the present invention, and the vibrating body (which can swing in both directions from its stable position) of the swing door is a pendulum body (86) such as a sphere or a cylinder, and a pendulum path (85) ). That is, the arm of the pendulum is formed by a trajectory, and belongs to the class of the pendulum in terms of vibration engineering. At the time of vibration such as an earthquake, the pendulum body (86) moves in the pendulum orbit (85). When the amplitude exceeds a certain level, the pendulum body (86) falls into a hole provided in the pendulum orbit (85) (ie, locks). Position). The drop into the hole naturally drops due to gravity. The reason why the magnet (87) is provided at the bottom of the hole is that a pendulum (86) made of a magnetic material such as steel is attached to the magnet (87). This is for stopping the fluctuation by causing the suction. On the other hand, the suction plate (20) attached to the hinged door (62) is
When 2) is closed, it penetrates into the middle of the hole of the pendulum orbit (85) and does not hinder the passage of the pendulum body (86) in its own holes (21) and (22). If the door (62) is to be opened in this state, one of the holes (2) is opened.
2) is first closed to lock the pendulum (86). Next, the other hole (21) is locked by the pendulum body (86), and the opening of the hinged door (62) is prevented and locked. To release, if the hinged door (62) is pulled strongly, the pendulum body (86) will spring (8).
This is achieved by being pushed down against the force of 8).
