Description

[Detailed explanation of the invention] (a) Technical field of the invention This invention relates to a magnetic catch that is provided as a locking means for locking the door of furniture or household electrical equipment, etc. This invention relates to a magnetic catch whose magnetic attraction surface can be adjusted forward and backward.

(b) Background of the invention In general, this type of magnetic catch has a magnet body attached to the main body side of, for example, furniture.
A magnetic adsorption plate is fixed to the door side opposite to this, and when the door is closed, these plates face each other and magnetically adsorb, thereby serving as means for locking the door.

However, when installing the magnet body and the magnetic adsorption plate, it is necessary to set the magnetic adsorption spacing to an interval suitable for the closed state of the door. Not only does it take a lot of time, but once it is installed, it is not easy to readjust the magnetic adsorption interval, making it troublesome to attach and adjust the attachment part.
This had the problem of requiring a lot of work effort.

(c) Purpose of the invention Therefore, the object of this invention is to provide a magnetic catch that can eliminate the troublesome operation of mounting the mounting part, reduce work effort, and exhibit high magnetic attraction.

(d) Summary of the invention This invention has a magnetic slider equipped with a magnet at the front and an inclined guide surface that slopes back and forth with respect to the vertical direction. An elevating piece that moves up and down in sliding contact with the elevating piece, and a nut that is held in place to prevent rotation are provided on the elevating piece,
An adjustment bolt that can be rotated from the outside of the case is screwed into the nut, and the magnetic slider is configured to be adjusted forward and backward from the front of the case based on the rotation of the adjustment bolt. It is characterized by being Tsutokiyatsuchi.

(E) Effect of the invention According to this invention, by rotating the adjustment bolt, the elevating piece via the nut moves up and down along the inclined guide surface, and the magnetic slider moves forward and backward from the front of the case. After this magnetic catch is installed at a magnetically compatible position with an appropriate spacing, the adjustment bolt can be rotated to finely adjust the magnetic attraction spacing suitable for the closed state of the door.

This eliminates the hassle of installing while considering the magnetic adsorption interval as is currently the case, and it is easy to install.Moreover, the magnetic adsorption surface of the magnetic slider
Even if pressure is applied from opening and closing the door, this force will not rotate the adjustment bolt, so the adjustment position of the magnetic slider will not change due to use, and the adjustment position will be reliably maintained. Good suction fixation of the door can be maintained.

(F) Embodiment of the invention An embodiment of the invention will be described below in detail based on the drawings.

The drawings show a magnetic catch, and in FIGS. 1 to 3, this magnetic catch 11 has a magnetic slider 12, a lifting piece 13, and a nut 14.
, an adjustment bolt 15, and a case 16 that houses and holds these.

The above-mentioned magnetic slider 12 has a magnet accommodating part 17 which is opened vertically on the front side, and this magnet accommodating part 17 houses a magnet 18 and upper and lower parts that hold the magnet 18 from above and below. The lower yokes 19 and 20 are stored and held together, and on the rear side, in the vertical direction,
Inclined guide surfaces 21, 21 whose front and rear surfaces are parallel and inclined
A rectangular slide hole 22 having a shape is vertically pierced,
The above-mentioned lifting piece 13 and nut 14 are housed in this slide hole 22.

The above-mentioned elevating piece 13 has a rectangular shape that is housed in the slide hole 22, and its front and rear surfaces have inclined sliding contact surfaces 23, 23 that slide on the front and rear inclined guide surfaces 21, 21 in the slide hole 22. It has a loose through hole 24 in the center of the upper surface for vertically passing an adjustment bolt, which will be described later, and a rectangular nut 14 on the rear side surface to prevent rotation. Nut storage groove 25 for storing and holding in piece 13
A nut 14 is inserted into this housing groove 25 by cutting out the nut 14.
An adjustment bolt and nut 14, which will be described later, are screwed together in a state in which the adjustment bolt 14 is housed.

The above-mentioned adjustment bolt 15 extends through the case 16 and the magnetic slider 12 housed in the case. It is inserted through the insertion hole 27 extending vertically through the center of the upper surface of the case 16, and when inserted, the male thread of the adjusting bolt 15 is screwed into the female thread of the nut 14, and the lifting piece 13 is loosely inserted through the free through hole 24. A retaining plate 29 is fitted onto the small-diameter shaft portion 28 at the lower end of the loose bolt 15 and fixed to the case 16, thereby restricting vertical movement of the adjusting bolt 15 and allowing only rotational operation. is allowed. In the figure, 30
are screws for mounting the case.

The magnetic catch configured in this way is
Attach the magnetic sliders 12 to the furniture body side or door side at appropriate intervals without requiring fine adjustment, and then rotate the adjustment bolts 15 to set the magnetic adsorption intervals to the case. You can adjust the forward and backward movement from the front. At this time, the rotational force of the adjusting bolt 15 is applied via the nut 14 to the vertical sliding action of the slope guide surfaces 21, 21 of the lifting piece 13 and the slope sliding contact surfaces 23, 23 of the slide hole 22. The magnetic slider 12 is converted into a moving force that moves the piece 13 in the vertical direction, and the magnetic slider 12 is pushed forward and retracted by the pressing force against the inclined surface when moving up and down, and is retracted to move forward and backward.

It should be noted that the larger the amount of vertical movement of the lifting piece 13 is set, the larger the amount of movement of the magnetic slider 12 can be set.
