Description

[Detailed description of the invention] [Industrial field of application] The present invention is designed to use the four corners of the frame material that fit on the four side edges of the sliding door, especially the upper left and right corners, to connect the frame materials and support the sliding door. The present invention relates to an upper support for steadying a sliding door, which has a simple structure but can firmly connect frame members, support the sliding door, prevent swinging of the sliding door, and enable smooth opening and closing of the sliding door.

[Conventional technology and problems]

For example, when partitioning a room or using a sliding door for a storage area for clothes, etc., rails are installed on the ceiling and floor and multiple door panels are fitted into the door so that they can be removed as needed. In order to open and close the door freely, a sliding door system is used, in which a door roller is installed below the door plate, or the door roller is attached above and suspended so that it can slide on each rail, and other methods.

Regardless of whether it is a removable fixing method or a sliding door method, frame materials are attached to the four side edges of the door panel, and the connection method also requires a frame material with a specific joint structure. You can fit single parts of the frame material together and connect them to each other by fitting them to the panel material, or join them together with screws, etc., or fit the frame material to the door panel material and attach appropriate connectors at the four corners of the frame material. It is also used to combine the elements. Furthermore, when using the sliding door method, a support such as a door wheel that can be hung and slid is attached to the upper side.
Some methods include attaching the door roller to the bottom.

These supports and connections must have appropriate strength and prevent sliding, since even if the door plate and frame are made of lightweight materials, they will inevitably be quite heavy. It is desirable that it be something that can be done smoothly. In addition, recently, mirrors have been increasingly used on walls to make the room feel larger, but when using mirrors for sliding doors, the weight increases even more, so the above requirements are even stronger. It's summery.

However, conventionally, when fitting and joining a frame material to a door panel material, appropriate connection plates are used at the four corners to connect the two, for example, with screws, and the upper and lower supports or door wheels are connected to each other. If the sliding door is installed separately and the sliding door is installed at a predetermined location, the sliding door will swing and cause trouble when opening and closing, and this will require a support rail with a complicated shape. Connectors, supports, door wheels, etc., are manufactured and used separately in shapes and sizes that suit each location. There were problems such as lack of compatibility and economic disadvantage.

[Means and examples for solving problems]

The inventor of this invention has made various efforts to create an upper support that has a strong supporting force, can firmly connect the frame materials, and can open and close the sliding door smoothly, and is integrated with the connector, and has achieved bilateral symmetry. The present invention was developed based on the discovery that the object could be achieved by attaching a guide section with good sliding properties to the connector section provided with each locking section. That is, the present invention forms grooves and ears, and has a clasp and a locking claw at the upper end.
