JPH04119580U - Closing device for opening/closing door - Google Patents

Abstract

(57) [Summary] [Purpose] To provide a closure that can be easily opened by keeping the attraction force constant even if the magnetic force of the magnet is changed, and can be easily opened even by a person with weak finger strength. [Structure] The relative position of the magnet of the door closing tool and the magnetic catch can be changed.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea was developed for use with door closures, especially magnets used in copying machines, etc. Relating to a closure consisting of a cut catch.

0002

[Conventional technology]

Magnets and magnetic catches are used in conventional door closures for copying machines, etc. The one consisting of is commonly used.

0003

[Problem that the idea aims to solve]

However, conventional door closures such as those described above do not use magnets or magnets. In addition to the area of each catch being constant, the installation position is also constant. Therefore, if there are variations in the magnetic force of the magnet, the absorption The adhesion force changes, the opening/closing force of the door is inconsistent, making it difficult to open, and the magnetic force of the magnet If the opening is large, there is a problem in that it is difficult for people with weak fingers to open the opening.

0004 Therefore, the purpose of this invention was to solve the problems of conventional closures as mentioned above, and to Even if the force varies, it is easy to open by keeping the adsorption force constant, and the magnet's magnetic To provide a closure that can be easily opened even by a person with weak finger strength when a large amount of force is applied. It's in the country.

[0005]

[Means to solve the problem]

This idea uses magnets and magnetic caps to achieve the above objectives. This feature is characterized in that the relative position with respect to the switch can be changed.

[0006]

[Effect]

In this invention as mentioned above, the magnetic force of the magnet is Change the mounting position of the magnet or magnetic catch on the opening/closing door, and Even if the magnitude of the magnetic force changes, the attraction force remains constant, or if the magnetic force is large, the attraction force remains constant. This will reduce the force of application.

【Example】

In the first embodiment of this invention shown in FIGS. 1 to 4, 1 indicates a magnet; The magnet 1 has vertically oriented long holes 3 in both sleeve plate parts 6 of the substrate 2, and a protrusion in the middle thereof. A plurality of (two in this embodiment) horizontal magnet pieces 5 are provided in the portion 4. . 7 indicates a magnetic catch, and this magnetic catch 7 is inside the both sleeve plate parts 8. At a position facing the magnet piece 5 in between, from above to below (in this embodiment) or is provided with a protrusion 9 that slopes from the bottom to the top, and the plate portions 8 on both sleeves are provided with a protrusion 9 that corresponds to the long hole 3. A long hole 10 is provided at a position facing the same direction. In a second embodiment of this invention shown in FIG. , long holes are provided in both sleeve plate portions 8 of the magnet 1 or the magnet catch 7 (this example). Instead of 3 or 10, one has a normal hole 11, and the other has an arc shape centered on the center of hole 11. The hole is 12.

[0008] A long hole in the opening/closing door 14 or 15 of the magnet 1 or magnetic catch 7 as described above. 3 or 10 with screws 17 or 18, and then attach the magnet in the opposite position. Catch 7 or magnet 1 will be installed in the same way. Due to the magnetic force of magnet 1, for example, if the magnetic force is large, in the first embodiment, the magnet Either move the net 1 downward using the elongated hole 3 as a guide, or use the magnetic catch 7 as a guide. The rod moves upward using the elongated hole 10 as a guide, as shown by the chain line in the second embodiment. Place the magnet 1 or magnet cap along the arcuate hole 13 around the center of the hole 12. By tilting the switch 7 to reduce the suction area, the suction force can be reduced, and vice versa. Conversely, if the magnetic force is small, increase the attraction force to keep it constant, or It will be either large or small.

[0009]

[Effect of the idea]

This idea is as mentioned above, and the magnet and magnetic catch are used for opening and closing doors. Since the mounting position of the magnet can be changed relative to the other, the magnetic force of the magnet can be changed. If so, change the adsorption area of both to small or large depending on the size of the adsorption area. The force can be made constant or small, so the door always needs to be opened with a constant force. It can be opened easily, and even people with weak fingers can open it easily. It has the effect of being able to
