Description

[Detailed description of the invention] The present invention is designed to connect a sliding door whose opening can be closed so that it is flush with or close to an adjacent sliding door or a fixed wall in the closed state. The present invention relates to a sliding door device that is suspended and supported so as to move in a direction perpendicular to the door surface over different positions.

Although the device is a sliding door, it has the advantage of being able to position the door in a flush state with a beautiful appearance in the closed state.

However, such sliding door devices have the disadvantage that because the sliding door is suspended and supported, it tends to shift due to slight vibrations, and furthermore, between the fully closed position and the position immediately before fully closed, the sliding door is suspended in the direction perpendicular to the door surface. Since the door is moved in a direction that has It has the disadvantage of making a rattling noise.

In order to solve this drawback, it is possible to prevent the sliding door from moving by, for example, providing a hook that hooks and fixes the sliding door in the fully closed position and the periphery of the opening. Since the direction of movement between the fully closed position and the position immediately before fully closed is delicately set, a high degree of precision is required for attaching the hook, and the sliding door also has the drawback of being cumbersome to operate when opening and closing the door. In particular, if the sliding door is moved forcefully to the fully closed position, the sliding door may easily bounce back from the fully closed position and come to rest in a position that cannot be fixed even by operating the metal fittings. It is necessary to move it to the fully closed position again.

The present invention was developed in view of the above-mentioned circumstances, and although it is possible to reliably prevent the movement of the sliding door in the fully closed position with simple construction by devising the sliding door fixing device, it is possible to prevent the sliding door from moving in the fully closed position. An object of the present invention is to provide a sliding door device that can be opened and closed easily and smoothly.

The characteristic structure of this invention to achieve the above purpose is as follows:
In the sliding door device described above, one suction member is attached to the sliding door in a desired orientation on the end face of the sliding door in the closing direction, and the suction member is attached to the periphery of the opening to fully close the sliding door from a position immediately before fully closing. The present invention is characterized in that a magnetic catch is provided which includes one suction member and the other suction member that adheres to each other as the sliding door is moved to a certain position and fixes the sliding door to the periphery of the opening. It produces the following effects.

That is, one suction member constituting the magnetic catch is attached to the sliding door, and the other suction member is attached to the periphery of the opening, and as the sliding door is moved from the position immediately before fully closed to the fully closed position, both suction members are attached. The parts are attracted to each other, and this attraction force fixes the sliding door to the periphery of the opening, preventing the sliding door from moving in the fully closed position, so even if the sliding door is moved vigorously to the fully closed position, it will not bounce back from the fully closed position. It can be easily opened and closed without any special fixing or fixing operations.

In addition, since one suction member attached to the sliding door is attached in a position facing the end face of the sliding door in the closing direction, the other suction member can be made to protrude toward the opening and can be attached without narrowing the opening. , it does not require high precision to determine the relative mounting positions of both suction members, and can be easily constructed.

Furthermore, regardless of whether the sliding door moves in a direction perpendicular to the door surface between the fully closed position and the immediately before fully closed position, there is no risk of the suction member protruding into this moving path. Sliding doors can always be opened and closed smoothly.

Therefore, we have developed a sliding door device that can reliably prevent the sliding door from moving in the fully closed position with a simple installation of an adsorption member on the sliding door and the periphery of the opening, while also allowing the sliding door to be opened and closed easily and smoothly. We have now been able to provide the following.
