Abstract

(57) [Summary] (Modified) [Purpose] To provide a runner device for a sliding door that adjusts the sliding condition of the sliding door and prevents an accident such as the falling of the door by preventing it from rising. . [Structure] A leaf spring 3 which elastically comes into contact with an upper end surface of an upper frame 11 of a sliding door 1 or an upper wall surface of a groove of a kamoi with which the upper frame fits.
It is characterized by installing. [Effect] The sliding condition of the sliding door can be adjusted to prevent the door from falling over.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sliding door runner device capable of adjusting the sliding condition of a sliding door.

[0002]

[Prior art and its problems]

 Generally, there are sliding doors such as shoji screens and sliding doors as partitioning doors.However, sliding doors with door rollers have very good sliding properties and can be opened and closed with a small amount of force, which is convenient, but sliding is too good. If you close it vigorously, there is a problem that the door bounces and opens halfway, or it opens naturally when the sill is slanted due to bad standing, and the door rail is a V-shaped rolling groove. In the case of a car with a door, there is a problem that when the door is subjected to a large lateral pressure, the door roller derails and the door falls.

[0003]

[The purpose of the device]

 In order to solve the above-mentioned problems of the prior art, the present invention provides a sliding door runner device that adjusts the sliding condition of the sliding door and prevents the accident of falling of the door by eliminating the lifting of the door. It is intended to be provided.

[0004]

[Disclosure of device]

 The runner device for a sliding door according to the present invention has elasticity on the upper surface of the upper frame of the sliding door or on the upper wall of the Kamoi groove where the upper frame fits, and on the upper wall of the Kamoi groove or the upper surface of the upper frame of the sliding door. It is characterized by the fact that a leaf spring that comes into contact with it is attached.

[0005]

[Function of the device]

 Since the leaf spring has elasticity and is in contact with the upper wall of the Kamoi groove or the upper frame of the sliding door, optimum sliding resistance occurs on the sliding door, preventing the door from bouncing open and natural opening, and lifting the door. Is prevented.

[0006]

【Example】

 Fig. 1 is a front view of a sliding door equipped with the runner device of the present invention in a standing state, Fig. 2 is a perspective view of a leaf spring attached to the sliding door side, and Fig. 3 is a leaf spring attached to the Kamoi side. 1 is a schematic plan view of a state in which 1 is a sliding door, 2 is a duck, and 3 is a leaf spring having a curved portion 31. As shown in FIG. 4, the leaf spring 3 is fixed to a slippery synthetic resin base plate 4 by means such as caulking, and the curved portion 31 is pressed and deformed, and its end portion 32 is fixed to the substrate 4. When sliding on, the frictional resistance is extremely small so that no frictional resistance occurs except between the curved portion 3 and the surface of the opponent. In the case of FIG. 2, the leaf spring 3 is fixed to the upper end face of the center of the upper frame 11 of the sliding door 1 together with the base plate 4 in the case of FIG. There is. In the case of FIG. 2, the curved portion 31 of the leaf spring 3 is on the upper wall surface of the groove 21 of the kamoi 2, and in the case of FIG. 3, the curved portion 31 of the leaf spring 3 is on the upper end surface of the upper frame 11 of the sliding door 1. Since they come into contact with each other by a restoring force, when the sliding door 1 is opened and closed, a frictional resistance is generated in the sliding door by the curved portion 31 of the leaf spring 3, and an appropriate brake is applied to the sliding door. The sliding condition is adjusted by changing the restoring force of the leaf spring 3, that is, the degree of bending to adjust the frictional resistance.

[0007]

[Effect of device]

 According to the sliding door runner device of the present invention, a leaf spring that has elasticity and comes into contact with the opposite surface is attached to the upper end surface of the upper frame of the sliding door or the upper wall surface of the groove of the kamoi. The sliding condition of the sliding door can be adjusted to prevent the door from bouncing open or the natural opening due to poor standing, and the runner prevents the door from rising and prevents the door wheel from slipping. It is possible to prevent accidents such as a sliding door falling.

Although the leaf spring of the device of the present invention may be provided at a plurality of positions, it contacts the central portion of the upper frame on the sliding door side and a part of the sliding door on the kamoi side when the sliding door moves left and right. The function can be sufficiently achieved by providing only one place in each possible place.
