[Industrial application] The present invention is designed so that when the slider is released from the case and is projected to the maximum extent,
The present invention relates to a push latch having a structure in which a suction surface of the slider is inclined with respect to a front end surface of the slider and a mechanism for easily detaching an object to be sucked adsorbed by the slider is provided and the structure thereof is simplified.

[0002]

2. Description of the Related Art When a slider is released from its case by releasing its locked state, the suction surface of the suction portion of this slider is gradually inclined with respect to the slider tip surface, and finally this suction portion is the slider tip. The push latch which is completely internally installed from the surface and allows the detachment operation of the adsorbed object adsorbed to the adsorbed portion to be easily performed is disclosed in, for example, Japanese Utility Model Publication No. 2-1157.
No. 0 publication. In this push latch, a yoke is superposed on both sides of a magnetized body such as a permanent magnet on the slide tip side of a slider that is slidable inside and outside the case with one end open and biased outward, The support shaft, in which the suction part whose surface along the slider sliding direction is inclined so that the opposite side is narrower than the suction surface side is an inclined surface, is erected at the end on the far side with respect to the sliding direction of the slider The above-described operation is made possible by inserting the slanted long hole into the groove and inserting it into the groove of the case that is slanted in the direction intersecting with the long hole.

[0003]

However, such a push latch is troublesome because it is necessary to perform processing such as providing an inclined surface on a magnetized body such as a permanent magnet which is brittle and difficult to process, and the push latch is also difficult. Since the upright support shaft is designed to be guided at the intersection of the long hole provided in the slider and the groove provided in the case, the structure is complicated and there is a problem in processing and assembling.

The push latch according to the present invention has been devised in view of these problems. When the slider is released from the case and the protrusion is maximized, the suction surface of the slider tip is the slider tip surface. It is an object of the present invention to provide a push latch having a simple structure, which is inclined and has a mechanism for easily detaching an object to be adsorbed to the slider.

[0005]

In order to achieve such an object, according to the present invention, a case having one end opened is provided with a slider slidable in and out of the case and biased outward. A magnetizing body is provided between which the slider is locked and fixed when it is pushed into the case, and the locking mechanism is released when the slider is pushed again and the yoke is provided on the surface of the slider. And the suction surface at the tip of the slider faces the slide tip side so that the suction surface can swing to both sides, and one side of the slider in the sliding direction of the yoke and one of the inner surface of the case facing this side. On the other side, a guide part along the sliding direction of the slider that slidably installs this convex part is provided on the other side with its end on the case opening side when the slider is released from its locked state. Protrusions to this end constituted the push latch provided toward the side opposite to the case opening side in the positional relationship for locking in pushed state in slightly case than maximally protruded.

[0006]

Thus, such a push latch is provided on the opening / closing side of the door pivotally attached to the main body of furniture or the like in order to close the opening on the inner surface side of the main body of the furniture or the like in the form of a box whose one surface is open. The guide part side is directed to the position corresponding to the side end side, and the slider side is attached from the opening side of the main body of furniture etc. to the outside, and at the position corresponding to the slider on the back surface of the door, the iron plate etc. Install the object to be adsorbed.

When opening a closed door of furniture or the like to which such a push latch is attached, the following is done. First, push the side edge of the door open / close side from the front side,
The slider is pushed into the case, the locked state is released, and the slider is projected to the front side by the urging force. At this time, the open / close side end of the door rotates toward the front side, but the door is attracted to the yoke of the slider through the attracted object against the inertial force of the door. Movement is restricted. When the slider protrudes and the side of the yoke provided in the slider in the sliding direction of the slider and the convex portion provided on one of the cases facing the yoke engage with the end of the guide portion provided on the other side on the case opening side. ,
The side of the yoke where the convex part and the end of the guide part are locked cannot further protrude, and at this time, the slider has not yet protruded to the maximum extent from the case. The side portion on the side opposite to the locking side is rotated to the side end side on the opening / closing side of the door. At this time, the door is rotating in the direction away from the yoke, and the contact area between the yoke and the side opposite to the locking side is rotated in response to the opening / closing side end of the door. Becomes smaller gradually. After that, the yoke is separated from the object to be adsorbed on the door, and the door is opened.

Next, when closing the door opened in this way, the side end of the door on the open / close side is pushed from the front side into the main body of furniture or the like, and the slider is locked and fixed to the case. At this time, by pushing the door into the main body of furniture,
Since the slider is pushed by the attracted object provided on it, the rotating state of the yoke is corrected by first pushing the side portion on the opposite side to the locking side toward the case with this attracted object.

Thus, such a push latch is a door 29 pivotally attached to the main body of furniture or the like to close the opening on the inner surface side of the main body of the furniture or the like in the form of a box whose one surface is open.
The guide portion 26 side is directed to the side end 29 'of the opening / closing side as shown in FIG. 5 at a position corresponding to the side end 29' of the opening / closing side, and the slider 2 side is opened from the opening side of the main body of furniture or the like. In addition to being mounted toward the outside, an object to be attracted 30 made of an iron plate or the like is mounted on the back surface of the door 29 at a position corresponding to the slider 2.

To open the closed door 29 of furniture or the like to which such a push latch is attached, do the following. First, when the side end 29 side of the opening / closing side of the door 29 is pushed from the front side, the slider 2 is pushed into the case 1 and its locked state is released, and the slider 2 projects toward the front side by its urging force. . When the slider 2 is pushed into the case 1, the locking projection 13 of the locking tool 9 in the state shown in FIG. 3 is separated from the locking recess 10 and the opening 11 of the locking portion 8 is sandwiched between them. While being abutted against the portion of FIG. 1 and rotated by the biasing force of the spring 4 to the left side in the figure, the biasing force of the spring 4 of the slider 2 then moves from the left side surface of the locking portion 8 to the right side surface of the figure. And moves to the state shown in FIG. Then, the length slider 2 shown by a in FIG. 3 projects. At this time, the side end 29 of the door 29 on the open / close side rotates toward the front side, but the door 29 is attracted to the yoke 20 of the slider 2 via the attracted object 30 against the inertial force. Therefore, the rapid turning operation is restricted. Then, the slider 2 projects and the convex portion provided on the yoke 20 of this slider 2
When 21 is locked to the end of the guide portion 26 provided in the case 1 on the opening side of the case 1, the yoke 20 is further protruded on the side portion where the convex portion 21 and the end of the guide portion 26 are locked. Since the slider 2 has not yet protruded from the case 1 to the maximum extent at this time, the slider 2 further protrudes from the case 1 by the length shown by b in FIG. The door 29 is rotated until it comes into contact with the ridge 22 on the side end 29 side of the opening / closing side. At this time, the door 29 is rotating in the direction away from the yoke 20, and the side portion of the yoke 20 opposite to the locking side is the door 29.
The contact area between the two gradually decreases in accordance with the rotation toward the side end 29 on the opening / closing side. After that, the yoke 20 is separated from the attracted object 30 of the door 29, and the door 29 is opened. In the illustrated example, the positions of the upper and lower guide portions 26, 26 on the opening side of the case 1 in FIG. 1 are displaced, so that the lower yokes 20, 20 first disengage from the attracted object 30 of the door 29, and then The upper yoke 20 is the door
It comes off from the object to be adsorbed 30 of 29.

Next, when closing the door 29 opened in this way, the side end 29 of the door 29 on the open / close side is pushed from the front side into the main body of furniture or the like, and the slider 2 is locked and fixed to the case 1. To do. When the side end 29 'of the door 29 on the open / close side is pushed into the main body of furniture or the like, the slider 2 in the state shown in FIG.
Is pushed into the case 1 and the locking protrusion of the locking device 9 of the case is pushed.
13 moves along the surface of the locking portion 8 on the right side in the figure to the end thereof, but since the locking tool 9 is biased in the direction of the center line O, the right end of the locking portion 8 If you get over the part, after contacting the opening 11 of the locking part 8 with the same height part sandwiched between them,
When the hand is released, the locking projection 13 is locked in the locking recess 10 of the locking portion 8.
Lock on. In this way, the closed state of the door 29 is fixed. At this time, by pushing the door 29 into the main body of furniture or the like, the attracted object 30 provided on the door 29 pushes the slider 2, so that the attracted object 30 changes the rotation state of the yoke 20 to the opposite side to the locking side. First, the side portion of is pressed in the direction of the case 1 to correct it.

Regardless of the illustrated embodiment, it is possible to provide the guide portion 26 and the auxiliary guide portion 27 on the yoke 20 side and the convex portion 21 on the inner surface side of the case 1. Further, the auxiliary guide portion 27 and the pin 21 incorporated therein can be omitted.
