Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a door opening device with a magnet.

Prior Art Generally, the outer periphery of the door and the inner periphery of the opening frame are
Airtightness between the door and the opening frame is achieved when the door is closed by attaching an airtight member made of rubber or the like on opposite sides, but in order to further enhance this airtightness effect, a magnet is inserted into the airtight member. This ensures that the airtight member and the airtight member are in complete contact with each other.

Problems that the invention aims to solve: However, although this configuration allows for airtightness between the door and the opening frame when the door is closed, it may not be possible to open the door easily if the magnet's magnetic force is strong. It was hot. In particular, children and the elderly were sometimes unable to open the door at all.

This invention was proposed to solve the above-mentioned conventional problems, and it goes without saying that it is possible to maintain airtightness between the door and the opening frame, and even children and the elderly can easily open the door. The object of the present invention is to provide a door opening device with a magnet.

Means for Solving the Problems This invention provides an airtight magnet opposite to the door periphery and the inner periphery of the opening frame, and also provides an airtight magnet on the top end surface of the door in conjunction with the door handle. A rotating block rotatable around the width direction and a spring member biasing the rotating block in a direction opposite to the block side are provided, and the rotating block is mounted on the lower surface of the upper frame of the door opening frame. The above object is achieved by providing a hit block against which the tip comes into contact.

Embodiment Hereinafter, this invention will be explained with reference to an embodiment illustrating the invention.A hollow portion 2 is formed at the peripheral edge of the door 1 and continues in the circumferential direction of the door 1 except for the lower stile. An airtight magnet 3 is inserted through the hole. An airtight member 5 is attached to the lower stile, and an airtight magnet 3 is attached to this airtight member 5.
On the other hand, an airtight member 5 is attached to the inner peripheral portion of the opening frame 4 so as to face the hollow portion 2, and an airtight magnet 3 is inserted through the airtight member 5.

With this configuration, when the door 1 is closed, the hollow part 2 of the door 1 and the airtight member 5 of the opening frame 4, and the airtight members 5 and 5 are brought into close contact with each other by magnetic force, so that the airtightness between the door 1 and the opening frame 4 is maintained. The gender is planned.

Further, a case 6 is attached to the upper end surface of the door 1 on the door end side, and a rotating block 7 is attached within this case 6.

The case 6 is made of metal or synthetic resin, and has a substantially rectangular opening 8 formed approximately in the center thereof.

The case 6 thus formed is screwed to the upper end surface of the door 1 on the door end side, and the opening 8 is embedded in the upper end of the door 1.

The rotating block 7 is made of metal or synthetic resin, has a substantially fan shape, and has a contact portion 9 formed at the upper end thereof. Further, a vertical groove portion 10 is formed at the lower end of the rotating block 7 on the front end side.

The rotating block 7 formed in this manner is installed in the opening 8 of the case 6 by pivoting its proximal end to the left and right side walls 8a, 8a of the opening 8 with pins 11. It is rotatable around the pin 11, that is, around the width direction of the door 1.

A pin 12 is horizontally attached to the vertical groove 10 of the rotating block 7, and the upper end of a connecting rod 13 is connected to the pin 12.

The connecting rod 13 extends between the handle 14 of the door 1 and the rotating block 7, and its lower end is connected to the cam 1 of the handle 14.
It is connected to 5.

Further, a spring member 16 is attached to the opening 8 of the case 6, and the rotating block 7 is attached to the spring member 16.
The spring member 16 is urged in the direction of rotation in the direction opposite to the contact block 17 side (counterclockwise direction in FIG. 1), and the spring member 16 is inserted through the pin 11 and one end thereof is hooked on the pin 12. , the other end is hooked to the edge 8b of the opening 8.

The upper frame 4a of the opening frame 4 in which the door 1 is built
A contact block 17 made of metal or synthetic resin is screwed onto the lower surface of the rotary block 7 so as to face the contact portion 9 of the rotary block 7.

In such a configuration, when the handle 14 is turned,
In conjunction with this, the connecting rod 13 slides in the vertical direction, and accordingly, the rotating block 7 rotates around the pin 11. When the rotating block 7 rotates toward the opening frame 4, the abutting portion of the rotating block 7 9 hits and presses block 17. As a result, the hollow part 2 of the door 1 and the airtight member 5 of the opening frame 4 are separated, and the door 1 can be opened easily.

Effects of the invention This invention has the above-mentioned configuration. According to this invention, the door can be opened halfway by simply turning the door handle or moving the handle. A door with a magnet that has an airtight magnet attached to the inner circumference of the door, so it can be opened easily even if the magnet's magnetic force is strong.

It goes without saying that the airtightness between the door and the opening frame is high when the door is closed.
