Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a magnetic catch for furniture that is used to hold the opening/closing door of various types of furniture such as wardrobes at the closed movement limit position. It is something.

(Prior Art and its Problems) This type of magnetic catch generally also serves as a stopper for regulating the closing movement limit position of an opening/closing door. Therefore, the position of the suction end portion that suctions the magnetic plate on the opening/closing door side must be set with high accuracy so that the door at the closing movement limit position maintains its normal position and posture.

Therefore, this type of magnetic catch is designed to be able to adjust the position of the suction end to the normal position even if there is some error in the front and back direction in the installation position on the furniture body side, and to It is required to be able to swing so that the suction end can come into surface contact with the magnetic plate on the door side even if there is some error in the left and right lateral directions in the mounting position.

Conventionally, as disclosed in, for example, Japanese Utility Model Application Laid-open No. 59-104943, an adjusting screw shaft for adjusting the position of the magnet unit having the attracting end portion in the front and back direction is provided, and As disclosed in Japanese Patent No. 77942, it is known that a magnet unit is pivotally mounted so as to be swingable from side to side.

Therefore, if the configurations of the above-mentioned two known examples are combined, the desired purpose can be achieved, but the conventional configuration (as disclosed in Japanese Utility Model Application Laid-Open No. 59-104943), which achieves the ability to adjust the longitudinal position of the magnet unit, (disclosed configuration)
In this case, the screw shaft passing through the magnet unit is held relative to the magnet unit so that it can only rotate on its own axis, and
Since the nut into which the rear end of the screw shaft is screwed is provided in the case at the rear position of the magnet unit, the configuration for such longitudinal adjustment and the support shaft of the magnet unit as described above are necessary. It was not possible to combine it with a configuration that allows it to swing from side to side around it.

In addition, since the adjustment screw must pass through the magnet unit, the thickness of the magnet unit cannot be made thinner, and a large space is required behind the magnet unit, which increases the depth of the magnet catch itself. It was hot too.

(Means for Solving the Problems) In order to solve the above-mentioned conventional problems, the present invention provides a case that is attached to the furniture main body, and a suction end that is movable back and forth so as to protrude from the front surface of the case. In the furniture magnetic catch, which includes a magnet unit housed in the case, and an adjusting screw shaft for adjusting the position of the magnet unit in the front-rear direction, the adjusting screw shaft is located on the side of the magnet unit. The magnet unit is supported so as to be able to rotate only in the front-rear direction at the front position, and a support shaft is protruded from the free end of a movable body that is screwed into the adjusting screw shaft and is movable in the front-back direction and extends to the rear position of the magnet unit. The present invention proposes a magnetic catch for furniture, in which the center portion of the rear end of the magnet unit is fitted onto the support shaft so as to be swingable from side to side.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

1 is a flat case, which includes a main body 1a and a bottom plate 1.
It consists of b. Reference numeral 2 denotes a driving fixture projecting from the case bottom plate 1b, and on its outer circumferential surface, retaining protrusions 2a having a circumferentially annular shape and a serrated cross section are provided in multiple stages in the axial direction.

A magnet unit 3 is housed in the case 1 so as to be movable in the front and back direction (in the direction of the arrow 4), and consists of a magnet body 5 and a pair of yokes 6 and 7 that sandwich this from above and below. Protrusions 6a and 7a for positioning the magnet body 5 are protruded from the edges, and upper and lower through holes 6b and 7b for pivoting are provided at the rear ends of the yokes 6 and 7 that protrude rearward from the magnet body 5. There is. The attracting end 8 of the magnet unit 3 projects outside the case 1 through an opening 9 formed in the front wall of the case body 1a.

Reference numeral 10 denotes an adjustment screw shaft, which is installed inside the case 1 at a position adjacent to the magnet unit 3 in parallel with the front-rear direction (arrow 4 direction), and its large diameter head 10a is
The screw shaft 10b is rotatably and loosely fitted into the opening 11 formed in the front wall of the case body 1a with its surface substantially flush with the other, and the rear end of the screw shaft 10b is formed inside the rear wall of the case body 1a. It is rotatably fitted loosely into the recessed portion 12. Furthermore, a retaining protrusion 13 protruding from the case bottom plate 1b is loosely fitted into an annular groove 10c formed near the rear end of the large-diameter head 10a, thereby preventing the adjustment screw shaft 10 from coming out from the opening 11. This prevents rotation and allows only rotation.

14 is a movable body, one end of which is connected to the screw shaft portion 10b of the adjustment screw shaft 10 in the through screw hole 14a.
The other end portion is loosely fitted between the rear end portions of the pair of upper and lower yokes 6, 7 of the magnet unit 3, and the support shafts 15a, 15 are vertically protruded from the other end portion.
b is a vertical through hole 6b for pivoting the rear end of the yoke;
7b, and is pivotally mounted so that the magnet unit 3 can swing left and right within a certain range.

The magnetic catch configured as described above is attached, for example, to a door locking position on the furniture body using a driving fixture 2. That is, a hole with an inner diameter suitably smaller than the diameter of the retaining protrusion 2a of the driving fixture 2 is bored at the door locking position on the furniture body side, and the driving fixture 2 is inserted into the hole. The case 1 is fixed in a predetermined position so that the attracting end 8 of the magnet unit 3 protruding from the case 1 faces straight ahead.

The magnetic catch installed in this way is similar to the conventional magnetic catch of this type.
When the door is moved to the closing limit position, the magnetic plate attached to the inside of the door is held by suction at the suction end 8 of the magnet unit 3. The position, ie, the position of the attracting end 8 in the magnet unit 3, can be adjusted as follows.

That is, the adjustment screw shaft 10 is inserted from outside the case 1 with a suitable tool such as a screwdriver through the rotation operation groove 10d formed in the large-diameter head 10a of the adjustment screw shaft 10.
By rotating the magnet unit 3, the magnet unit 3 can be moved back and forth (in the direction of arrow 4) via the movable body 14 that is screwed onto the threaded portion 10b of the adjustment threaded shaft 10. This makes it possible to adjust the position of the suction end 8 protruding from the case 1 back and forth. By adjusting the longitudinal position of the suction end 8, it is possible to correct the position and posture of the door held by the suction end 8 at the closed movement limit position.

Furthermore, since the magnet unit 3 can swing within a certain range left and right around the pivot shafts 15a and 15b between it and the movable body 14, the magnetic plate on the door side and the suction end of the magnet unit 3 It is possible to reliably adsorb the portion 8 in a state of surface contact.

It should be noted that, without using the driving fixture 2, for example, the flange portion protruding from the case bottom plate 1b may be configured to be fixed to the furniture body side with wood screws or the like.

(Operations and Effects of the Invention) As described above, according to the magnetic catch for furniture of the present invention, the magnet unit can be swung in the left and right directions around the spindle, and the self-supporting unit can be rotated by the rotation of the adjusting screw shaft. The position can be adjusted in the front-rear direction by operation, and the adjustment screw shaft is supported so as to be able to rotate only in the front-rear direction at a lateral position of the magnet unit, and is screwed onto the adjustment screw shaft. Since the center part of the rear end of the magnet unit is fitted into the support shaft protruding from the free end of the movable body extending to the rear position of the magnet unit, the center part of the rear end of the magnet unit can swing from side to side. Compared to the case where the adjustment screw shaft has to pass through, the magnet unit can be constructed thinner and simpler;
Furthermore, since it is necessary to secure a space behind the magnet unit in which only the horizontally extending portion of the movable body can be loosely fitted, the depth of the magnet catch can be narrowed and the entire structure can be made compact. I can do it.
