Description

[Detailed description of the invention] The present invention is designed to connect a sliding door flush with or close to an adjacent sliding door or a fixed wall in the closed state, so that the sliding door can be connected flush with or close to the sliding door adjacent to it in its 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 , and that is provided with a guide mechanism for the lower part of the sliding door.

Although the device is a sliding door, it is possible to position the door in a flush state with a beautiful appearance when it is closed, and it also makes cleaning easier because there is no guide groove for the door at the bottom. Further, due to the action of the guide mechanism, it is possible to prevent the door from rattling, and the door can be opened and closed easily and without damage.
However, this type of conventional sliding door device has a guide for moving the lower end side of the sliding door in a direction perpendicular to the door surface, as shown in, for example, Japanese Utility Model Application Publication No. 53-85322. The lower part of the mechanism is provided in an exposed state on the floor surface of the bottom of the furniture, and
The guide mechanism is fixed to the bottom of the furniture on the back side of the floor, so when the sliding door is removed for cleaning, the exposed guide mechanism does not get in the way of cleaning. As a result, it is difficult to avoid inconveniences such as damage to items and the risk of injury.In addition, in order to remove the guide mechanism, it is necessary to disassemble the bottom of the furniture that makes up the floor surface, making it easy to remove. When it comes to furniture that is difficult to move, or in fixed storage areas, it is difficult to disassemble the furniture itself, which is an unavoidable inconvenience.

As a means to prevent the guide mechanism from being exposed on the floor surface, for example, as shown in Japanese Utility Model Application Publication No. 53-94823, the guide mechanism is inserted into the guide groove on the lower end surface of the sliding door. It has been known in the past that only the guide body is made to protrude above the floor surface and the rest of the guide body is attached to the back side of the floor surface, but according to such a method, the guide body moves in the direction along the floor surface. It is necessary to drill a long hole in the floor surface to allow this, and dirt and insects can easily get under the floor surface through this long hole, making it unhygienic. This method could only be applied to furniture or floor structures that had a bottom thickness sufficient to form a space to accommodate the guide mechanism.

This invention improves the holder for fixing the guide mechanism to the floor, so that when the sliding door is removed, even in storage areas where there is not enough space to install the guide mechanism under the floor, Avoid leaving guide mechanisms, long holes, etc., and make cleaning easier.
The purpose is to provide a sliding door device whose guide mechanism can be easily removed and installed from the floor.

The feature of the present invention for achieving the above object is to suspend and support the sliding door so as to move it in a direction perpendicular to the door face between a fully closed position and a position immediately before fully closed, and In the sliding door device, a guide mechanism for the lower part of the sliding door and a holder for fixing the guide mechanism to the floor are provided on the floor side facing the lower end surface of the sliding door. A guide body that engages with a guide groove formed on a lower end surface to guide the movement of the sliding door in a direction along the door surface, and a guide body that moves in a direction perpendicular to the door surface to move the sliding door. a guide member that guides movement in a direction perpendicular to the door surface, and a holder for fixing this guide mechanism to the floor surface is attached above the floor surface; The holder includes a first mounting member fixed on the floor surface, and a second mounting member configured to be detachable from the first mounting member in a direction along the floor surface; The guide mechanism is provided on the detachable second mounting member, and this configuration provides the following effects.

That is, the holder is divided into a first mounting member fixed to the floor side and a second mounting member that is detachable from the first mounting member, and the second mounting member is detachable from the first mounting member. Since the guide mechanism is attached to the member, by removing the second mounting member when removing the sliding door, the guide mechanism, which has a complicated shape, can be removed from the floor. Since only the first mounting member, which has a relatively simple shape and structure, remains, there is an advantage that it is easy to avoid the possibility of impeding cleaning or causing injury due to getting caught during cleaning.

In addition, since the first mounting member is installed on the floor, there is no need to create a space for installing a guide mechanism under the floor of the storage unit, and there is an advantage that it can be applied to all types of storage units. In addition, since the first mounting member and the second mounting member are engaged and disengaged in the direction along the floor surface, the second mounting member and
The guide mechanism attached to the guide mechanism and the sliding door that engages the guide groove with the guide body of the guide mechanism can be engaged and detached from the first mounting member in a state where they are integrally combined, and the sliding door and the guide mechanism Another advantage is that it is easy to attach and detach.
