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 of the 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 surface of the groove of the Kamoi with which the upper frame fits, and on the upper wall of the groove of the Kamoi or the upper surface of the upper frame of the sliding door. It is characterized by having a runner that comes into contact with it.

[0005]

[Function of the device]

 Since the runner elastically contacts the upper wall of the Kamoi's groove or the upper frame of the sliding door, optimum sliding resistance is created in the sliding door, preventing the door from rebounding and opening naturally, preventing the door from opening naturally. Lifting is prevented.

[0006]

[Embodiment 1] FIG. 1 is a front view of a sliding door equipped with a runner device of the present invention in a standing state, FIG. 2 is an enlarged cross-sectional view of an essential part of a state where the runner is attached to the sliding door side, and FIG. FIG. 3 is an enlarged cross-sectional view of a main part in a state of being attached to the side, where 1 is a sliding door, 2 is a duck, and 3 is a runner. The runner 3 was interposed between the fixed-side frame member 31 having a U-shaped cross section and the sliding friction member 32 provided with a stopper so as not to separate from the frame member 31 and between the frame member 31 and the sliding friction member 32. In the case of FIG. 2, the frame member 31 is formed on the upper end surface of the upper frame 11 of the sliding door 1, and in the case of FIG. 3, it is formed on the upper wall surface of the groove 21 of the upper frame 2 respectively. It is fixed with screws. 32a are formed on the rubbing member 32 so that the contact resistance with the groove of the Kamoi or the sliding door is not too large, and the contact area is reduced. 32a of the rubbing member 32 is on the upper wall surface of the groove 21 of the Kamoi 2 in the case of FIG. 2, and in FIG. 3 the ribs 32a ... 32a of the rubbing member 32 are on the upper frame 11 of the sliding door 1. Since the elastic member 33 comes into contact with the end surface by the restoring force, when the sliding door 1 is opened and closed, a frictional resistance is generated by the sliding friction member 3 on the sliding door 1, and an appropriate brake is applied to the sliding door. The sliding condition is adjusted by adjusting the frictional resistance by the restoring force of the elastic member 33 or the increase / decrease of the number of the protrusions 32a ... 32a. In the case of FIG. 2, the runner 3 has a short length, that is, one divided into a plurality of pieces may be attached to the upper end surface of the upper frame 11 of the sliding door 1, but in the case of FIG. 3, the runner 3 has a long length. 2 must be installed over the entire length.

[0007]

Second Embodiment FIG. 4 is an enlarged cross-sectional view of a main part of a second embodiment of the device of the present invention, in which a rubbing member 32 is directly attached to an elastic member 33 made of foam such as sponge with an adhesive or the like. The runner 3 is constructed by wearing the runner 3, and the runner 3 is attached to the upper wall surface of the groove 21 of the kamoi 2 with double-sided tape or the like. In the case of this runner, since the sliding friction member 32 is directly fixed to the elastic member 33, the sliding friction member 32 shifts in the opening and closing direction each time the sliding door 1 is opened and closed, and an unreasonable force acts on the elastic member. As in the case of FIG. 3, it is preferable to install the runner over the entire length of the Kamoi 2 rather than dividing the runner into a plurality of parts and mounting them on the sliding door side as shown in FIG.

[0008]

[Effect of device]

 According to the sliding door runner device of the present invention, since the runner that has elasticity and comes into contact with the mating 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 can be adjusted, and it is possible to prevent the door from bouncing open or the natural opening due to poor standing, while the runner holds it down to prevent it from rising, and the door wheel derails and the door falls. It is possible to prevent such an accident.
