Sliding door track

A hardware fitting for interior decoration of a building, in particular, a sliding door rail for providing a sliding sliding door on which a sliding door with a sliding door pulley is mounted.

The sliding door is generally divided into two types: an upper rail type and a lower rail type; here, the lower rail type of the pulley is mounted on the bottom of the sliding door, and the prior art is used for comparison. Related prior art such as "Reinforcement Structure Improvement" of the Republic of China Patent Certificate No. 549334; the prior art discloses a method of installing a sliding door at the bottom of the sliding door so that the sliding door can be moved up the track by the pulley block, and the pulley block comprises a casing. A wheel set is mounted in the casing, the wheel set is composed of a roller and a wheel seat, and a shaft hole is arranged on one side of the bottom edge of the wheel set, and a shaft hole corresponding to one side of the bottom edge of the casing is provided by a shaft rod. The shaft is set, the 轮 wheel set pivots with the shaft as the axis, and the upper part of the wheel set is provided with an opening clamp, the clip is clamped with the sheet body, and the screw is screwed through the inside of the shell The body is provided with the function of adjusting the wheel set.

It is clear from the above prior art that after the production is carried out, in order to cooperate with the pulley block, the operator will design a track that matches the roller of the pulley block, and in order to prevent the roller from being engaged with the track. The size of the track must be relatively larger than that of the roller; therefore, once the sliding door is mounted on the pulley block and slides in conjunction with the track, the roller and the track are bound to have a gap, although it does not cause derailment. Phenomenon, but due to the existence of a gap between the roller and the track, it is not smoothly slidable, and there is a problem of sloshing, so that when the roller is in contact with the track, a large sliding sound is emitted, and Caused by consumer dissatisfaction; the above various defects, it is subject to further research and development and effective improvement.

Therefore, the main object of the present invention is to solve the above problems of the prior art. The new convex rail surface design not only provides the phenomenon that the sliding door is not easy to derail when the force is moved, but also makes the movement smooth, and there is no problem of swaying, so that the sliding door track and the sliding door can be greatly reduced. The noise problem caused by the pulley touching the friction.

In order to achieve the above object, the present invention provides a sliding door rail for inserting a door frame and fixing a sliding door with a sliding door pulley thereon; wherein the sliding door pulley includes a main body a wheel base coupled to the main seat body; and a pulley disposed in the wheel base and axially coupled thereto, and the pulley has an arcuate grooved wheel surface, and the groove wheel surface Each of the sliding door rails includes a convex rail surface matching the groove wheel surface; a side baffle respectively disposed on two sides of the convex rail surface; and a convex rail formed on the convex rail A receiving groove for receiving the wheel edge between the surface and the side baffle.

Further, the side baffle extends below an embedding portion that can be embedded in the lower door frame to be tightly hooked.

Further, wherein the upper end of the side baffle is bent outwardly and vertically.

Further, wherein the sliding door rail is an aluminum extrusion formed body.

The detailed description and technical content of this new model are as follows:

First, please refer to both FIG. 1 and FIG. 2, which are schematic perspective views and cross-sectional views of the preferred embodiment of the present invention. As can be clearly seen from the figure, a sliding door rail 1 proposed by the present invention is used for embedding a door frame 60 (as shown in FIG. 4) and providing a sliding door pulley 2 The sliding door 50 (shown in FIG. 4) is slidably displaced thereon; wherein the sliding door pulley 2 includes a main seat body 20; a wheel base 30 pivotally coupled to the main seat body 20; a pulley 40 that is axially coupled to the wheel base 30, and has a curved grooved tread 41, and a grooved surface 42 extends from each side of the grooved tread 41; and the push and pull The door rail 1 includes a convex rail surface 11 matching the groove wheel surface 41; a side fence 12 respectively disposed on two sides of the convex rail surface 11, and the upper end of the side fence 12 is bent outwardly; And a receiving groove 13 formed between the convex rail surface 11 and the side baffle 12 for receiving the wheel surface 42. In addition, the sliding door rail 1 further includes an engaging portion 14 extending from below the side fence 12 and embedded in the lower door frame 60 to be tightly hooked. The sliding door rail 1 can be an aluminum extrusion formed body.

Please also refer to "Figure 3" and "Figure 4" at the same time, which is a schematic diagram of the implementation of the sliding door track and the sliding door pulley of the present invention. As can be clearly seen from the figure, the sliding door rail 1 of the present invention is fixed under a sliding door 50 and is provided by a sliding door which can be matched with the groove wheel surface 41 of the pulley 40. Above the convex rail surface 11 of the rail 1 , the sliding door pulley 2 is guided to slide the sliding door 50; wherein the sliding door rail 1 has at least one engaging portion 14 under the sliding door rail 1 , and the engaging portion 14 The sliding door rails 1 are fixed to the door frame 60, and the sliding door rails 1 are respectively provided with a side baffle 12 on both sides of the convex rail surface 11, and the convex rail surface 11 and the side baffle 12 are respectively disposed. A receiving groove 13 for receiving the wheel edge 42 is formed between the two. According to the design of the grooved wheel surface 41 of the present invention, in addition to providing the phenomenon that the sliding door 50 is less prone to derailment when the force is moved, the movement is smooth, and the problem of sloshing does not occur, so that the sliding door 50 can be greatly reduced. The noise problem that the sliding door pulley 2 emits when it comes into contact with the sliding door rail 1.

Although the present invention has been disclosed above in the preferred embodiments, it is not intended to limit the present invention. Any modification or refinement made by those skilled in the art without departing from the spirit and scope of the present invention shall be covered by the present invention. Therefore, the scope of protection of the present invention is defined by the scope of the appended patent application. Prevail.
