Description

[0001]
BACKGROUND OF THE INVENTION
The present invention provides a magnet catcher that adsorbs a sliding door to a frame or a column with the force of a magnet so that the sliding door that abuts the frame or the column does not rebound or inadvertently open when the sliding door is closed. About.
[0002]
[Prior art]
A magnet catcher of a door configured with a magnet and a magnetic body adsorbed by the magnet as a pair is basically well known and a number of proposals have been made, and is used as a fixing device for a hinged door or a sliding door in a fitting, a storeroom, or the like.
[0003]
FIG. 5 shows a well-known example in which a magnetic catcher is used as a sliding door opening prevention device. A magnetic body 52 is provided on a contact surface of the frame body 50 with the sliding door 51, and the magnetic body 52 is connected to the frame body 50 of the sliding door 51. A magnet 53 is provided on the contact surface. When the sliding door 51 is closed, the sliding door 51 and the frame body 50 are attracted by the adsorption of the magnet 53 and the magnetic body 52 so that the sliding door 51 does not rebound from the frame body 50 or open carelessly.
[0004]
[Problems to be solved by the invention]
However, as shown exaggeratedly in the drawing, the conventional sliding door magnet catcher was closed when the frame 50 was distorted or deformed and a gap S was formed between the sliding surfaces of the sliding door 51 and the frame 50. Due to the return movement of the sliding door 51, the attracting force of the magnet 53 is lost and the attracting force does not work. Therefore, the sliding door 51 may move even if there is a slight inclination, or may be opened carelessly, and the closed state cannot be reliably maintained.
[0005]
In addition, when the frame 50 is not distorted and the sliding door 51 is closely attached to the frame 50, the sliding door 51 is firmly closed and maintains a closed state. It requires a strong initial power to shake off the adsorption power. For this reason, there is a problem that the operation load is heavy for a weak child or an elderly person, and there is a problem that the sliding door 51 is excessively moved due to excessive pulling, and the usability is bad.
[0006]
The present invention has been made in view of the above-described problems, and it is intended to make a magnetic catcher that is easy to open the sliding door while the sliding door is engaged with the frame even if there is a gap between the contact surfaces of the sliding door and the frame. is there.
[0007]
[Means for Solving the Problems]
The present invention, in the respective abutment surfaces of the sliding door and the frame, the magnet or magnetic body of the catcher body anymore one abutment surface provided with a catcher body having one of the contact surface to the magnet or magnetic body In the magnetic catcher of a sliding door provided with a catcher receiver having a magnet or a magnetic body to be adsorbed, a movable body is provided in the case of the catcher body so as to be slidable in the axial direction. A head having the magnet or the magnetic material, a thick shaft extending in an axial direction from the head and slidably penetrating a partition in the case, A stopper cap provided at the rear end of the thick shaft portion, and provided around the thick shaft portion so as to be sandwiched between the stopper cap and the partition wall, and in a direction of drawing the movable body into the case Elasticity It is configured to include a coil spring to exert, when the magnet or magnetic body of the catcher body and a magnet or magnetic body of the catcher receptacle opens the sliding door from sliding closed state adsorbed, the movable body after the adsorption of the magnet or magnetic body against the elastic force of the coil spring from the open end of the case until it is pulled out by a predetermined amount is maintained, with release of the suction, the movable body of the coil spring The case is drawn into the case by an elastic force, so that the open end of the case is flush with the head portion .
As a result, if the magnet is attracted by closing the sliding door, the movable body is pulled out from the catcher body as the sliding door returns, even if there is a gap between the sliding door and the frame, and the engagement between the sliding door and the frame is maintained. To do. Further, when opening the sliding door, inertia is accompanied by the initial movement of the sliding door, and the magnet can be easily attracted.
[0008]
Moreover, by making the case of the catcher body made of synthetic resin, the magnet is not magnetically attached to the case, and the movable body of the magnet can be operated smoothly.

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the accompanying drawings.
[0011]
1 to 3 show a first embodiment of a magnetic catcher for a sliding door according to the present invention. As shown in FIG. 3, the magnet catcher M includes a frame body 30 and a rail 31 of the frame body 30. In the present embodiment, the catcher body 1 is embedded in the contact surface 36 on the sliding door 35 side, and the frame body is installed. The catcher receiver 20 is embedded in the contact surface 32 on the 30 side. Note that, contrary to the illustration, the catcher receiver 20 may be embedded on the sliding door 35 side, and the catcher main body 1 may be embedded on the frame 30 side.
[0012]
The catcher body 1 includes a cylindrical case 2 made of synthetic resin having a partition wall 3 and a stopper step portion 4 on an inner peripheral wall, a fixing member 5 that closes a base end opening of the case 2, and a coil spring 6 in the case 2. The movable body 10 is retracted and accommodated in such a manner that the tip portion can be retracted from the opening end 2 a of the case 2.
[0013]
The movable body 10 has a thick shaft portion 11 slidably passing through a bearing hole 3a at the center of the partition wall 3 of the case 2, and a male screw portion 12 protruding from the center of the distal end surface of the thick shaft portion 11, A head 15 having a front surface and a side surface covered with a thin magnet cover 14 made of synthetic resin is screwed onto the male screw portion 12. A dish-like stopper cap 16 is fixed to the rear end surface with screws 17, and the base end surface of the head 15 is in contact with the front surface of the partition wall 3 of the case 2 and the stopper cap 16 is in contact with the fixing member 5. It is accommodated in the case 2.
[0014]
The coil spring 6 around the thick shaft portion 11 is elastic in a state in which one end abuts against the stopper cap 16 and the other end resiliently abuts against the rear surface of the partition wall 3 so that the movable body 10 is pulled into the case 2. It is worn while maintaining power. The movable body 10 drawn into the case 2 by the coil spring 6 is slidable in the axial direction with its front end surface, that is, the outer surface of the magnet cover 14 being flush with the open end 2a of the case 2.
[0015]
In addition, when using a magnet for the catcher receiving body 20 side, it may replace with the magnet of the movable body 10 by the side of the catcher main body 1, and may use a magnetic body.
[0016]
In order to attach the catcher body 1 to the sliding door 35, the fixing member 5 is fixed in advance to the inner surface of the mounting hole 37 that opens in the contact surface 35 of the sliding door 35 with the screw 7, and the case 2 incorporating the movable body 10 is attached. What is necessary is just to insert in the attachment hole 37, and to fix the rear-end part of case 2 and the adhering member 5 by screwing or undercut engagement.
[0017]
On the other hand, the catcher receiver 20 embedded in the contact surface 32 of the frame 30 so as to face the catcher body 1 is adjusted by engraving a male screw in the center of the recess 21a of the circular synthetic resin case 21. The body 22 is erected so as to be rotatable, and a ring-shaped magnetic body 23 is screwed into the adjusting body 22 and accommodated in the recess 21a so as to be able to advance and retreat.
[0018]
An engagement hole 22a for engaging the tip of the driver is formed in the tip surface of the adjustment body 22, and the adjustment body 22 is rotated by the driver to move the magnetic body 23 in the recess 21a, thereby catching the catcher receiver. The magnetizing force of the magnet catcher M is adjusted by providing a magnetizing interval between the 20 magnetic bodies 23 and the magnet 13 of the catcher body 1. The front surface of the catcher receiver 20 screwed to the frame body 30 is covered with a cover 24 made of synthetic resin.
[0019]
The magnet catcher M of the present embodiment is configured as described above, and even if the sliding door 35 is roughly closed, the magnet 13 and the magnetic body 23 are attracted and the sliding door 35 does not rebound from the frame 30 and is closed. Maintain state.
[0020]
The force relationship between the magnet attracting force and the coil spring 6 is such that when the sliding door 35 is opened from the closed state where the movable body 10 is attracted to the catcher receiver 20, the attracted movable body 10 resists the spring pressure. Until the stopper cap 16 of the movable body 10 abuts against the stopper step 4 of the case 2, the spring pressure is set to a spring pressure that allows the sliding door to move initially while compressing the coil spring 6. The separation of the magnetized surface is performed by the running force of the sliding door 35 after the movable body 10 is stopped by the stoppers 16 and 4.
[0021]
Therefore, even if the sliding door 35 is in close contact with the frame 30 and is magnetically attached, inertia is accompanied at the initial movement of the sliding door 35, so that it is possible to easily swing off and release the magnet.
[0022]
Even when the frame 30 is distorted or deformed and a gap is generated between the frame 30 and the sliding door 35 when closed, the movable body 10 adsorbed to the magnetic body 22 is returned to the catcher body as the sliding door 35 returns. The sliding door 35 is pulled out from the frame body 30 and held in the engaged state.
[0023]
When the sliding door 35 is released, the movable body 10 is drawn into the catcher body 1 by the coil spring 6. Therefore, the movable body 10 does not get in the way.
[0024]
Further, when the attractive force is too strong, the adjustment body 22 is used to take a distance between the magnetic body 23 and the magnet 13, and when it is weak, the magnetic body 23 may be adjusted so as to approach the magnet 13 as much as possible.
[0025]
As described above, the magnet catcher M according to the present invention is not limited to a combination of a magnet and a magnetic body, but a combination of N and S poles by magnets, and a catcher body provided with a magnetic body. The present invention is also applied to a combination in which a magnet is provided on the body, and a combination in which a catcher body is provided on a frame and a catcher receiver is provided on a sliding door.
[0026]
FIG. 4 shows another embodiment, which is basically the same as that of the first embodiment described above. Therefore, common portions are denoted by the same reference numerals as those of the first embodiment, and Description is omitted.
[0027]
This embodiment is for simplifying the installation work. As shown in the figure, the catcher body 1 has a plurality of retaining protrusions 8 protruding from the outer peripheral surface of the case 2. The rear end opening of the case 2 is closed by screwing the plug 9. The catcher body 1 is fixed to the mounting hole 37 of the sliding door 35 by driving.
[0028]
The catcher receiver 20 has a rubber disk-shaped receiving plate 25 and a disk-shaped magnetic body 23 provided to absorb an impact, and is accommodated in a mounting hole so as to pass through the center. It is fixed with. The magnetic body 23 may be directly fixed to the mounting hole.
[0029]
This embodiment is a simplified version of the first embodiment, and its operation. The effect is the same as in the first embodiment.
[0030]
【The invention's effect】
The present invention is implemented in the form as described above, and has the following effects.
[0031]
When the sliding door is opened from the closed state of the sliding door where the magnet of the movable body is attracted to the magnetic body of the catcher receiver, the movable body is pulled out from the opening end of the case of the catcher body against the elastic force of the coil spring. As a result, even if there is a gap between the sliding door and the frame, if the magnet is attracted when the sliding door is closed, the movable body will be pulled out of the catcher body by the return movement of the sliding door. Keep the sliding door and frame attached. Therefore, the sliding door is not inadvertently released even if it is built in a slightly poor state or in a slightly inclined state.
[0032]
Also, when opening the sliding door, the inertia of the initial movement of the sliding door is accompanied by the pulling operation of the movable body, so that the magnetic catcher can be easily absorbed, and the sliding door can be opened and closed more easily than the conventional magnetic catcher. Then, since the movable body is drawn into the sliding door, it does not get in the way.
