Description

Door closer assembly capable of improving smooth operation

This creation is related to the door closer, especially a door closer assembly that can improve the smoothness of operation.

In order to avoid the door panel being damaged due to excessive impact when it is opened or closed, the current common solution is to set a slide rail on the door frame, a slider in the slide rail, and a set of door closers on the door panel. The main arm forms a pivotal relationship with the slider. In this way, during the opening or closing of the door panel, the main arm is driven by the door panel to pull the slider to move in the slide rail, on the other hand, the door closer is driven, so that the door closer provides resistance to the door panel for stable operation.

However, the conventional slider has too many corners in its structure, so that during the movement in the slide rail, it is easy to rub against the slide rail to produce abnormal sounds, and it will also affect the smoothness of the slider's movement, resulting in the use of A person may need to exert a greater force to smoothly open or close the door panel, thereby causing trouble and inconvenience in use.

The main purpose of this creation is to provide a door closer assembly that can eliminate abnormal sounds generated during operation and improve smoothness during operation.

In order to achieve the above-mentioned main purpose, the door closer assembly of this creation is located between a door frame and a door panel pivoting the door panel. The structure includes a slide rail, a slider, a door closer, and a main arm. The slide rail is provided in the door frame and has a slide groove; the slider has a circular cross-sectional shape, and the slider is provided in the slide groove of the slide rail in a slidable manner; the door closer is provided in the The door panel has a transmission shaft; one end of the main arm is pivotally connected to the slider, and the other end of the main arm is connected to the transmission shaft of the door closer, so that the main arm will pull the slider when the door panel is opened or closed It moves in the chute and drives the drive shaft of the door closer at the same time, so that the door closer provides a cushioning effect and allows the door panel to move steadily.

As can be seen from the above, the door closer assembly of this creation uses a slider with a circular cross section to reduce the mutual friction with the slide rail, thereby achieving the effects of eliminating abnormal noise and improving the smoothness of operation.

Preferably, the cross-sectional shape of the slide groove is T-shaped and has a large groove portion and a small groove portion, and the slider has a large ring portion and a small ring portion coaxially connecting the large ring portion, the slide The large ring portion of the block is slidably embedded in the large groove portion of the sliding groove, and the small ring portion of the slider is slidably embedded in the small groove portion of the sliding groove.

Preferably, one end of the main arm has a convex shaft, the convex shaft has a large shaft portion and a small shaft portion coaxially connected to the large shaft portion, and the large ring portion of the slider is rotatably sleeved on The large shaft portion of the convex shaft, and the small ring portion of the slider are rotatably sleeved on the small shaft portion of the convex shaft.

The detailed structure, characteristics, assembly or use of the door closer assembly provided by this creation will be described in the detailed description of the subsequent embodiments. However, those with ordinary knowledge in this creative field should be able to understand that these detailed descriptions and the specific examples listed for implementing this creative are only used to illustrate this creative, not to limit the scope of patent applications for this creative.

The applicant first states here that throughout the specification, including the embodiments described below and the claims in the scope of patent application, the directional terms are based on the directions in the drawings. Secondly, in the embodiments and drawings to be described below, the same element numbers represent the same or similar elements or their structural features.

Please refer to FIGS. 1 and 2. The door frame 11 shown in FIG. 2 has an upper frame bar 12 and two side frame bars 13. The top ends of the two side frame bars 13 are connected to two opposite ends of the upper frame bar 12. The top edge of the door panel 14 shown in FIG. 2 has a recess 15 and a blocking wall 16. The bottom surface of the recess 15 has a receiving groove 17. The blocking wall 16 is adjacent to the outer side of the recess 15.

Please refer to FIG. 2 again. The door closer assembly 10 of the present invention includes a slide rail 20, a slider 24, a door closer 40 and a main arm 50.

The slide rail 20 is made of a metal material and is fixed to the bottom surface of the frame strip 12 above the door frame 11 with a fixing element 21 such as a screw. The slide rail 20 has a slide groove 22, and two end covers 25 are respectively provided at two ends of the slide rail 20, and the two end covers 25 close the two ends of the slide groove 22 to each other. In addition, as shown in FIG. 4, the cross-sectional shape of the slide groove 22 is T-shaped and has a large groove portion 23 and a small groove portion 24 communicating with the large groove portion 23.

The slider 30 is made of plastic material. As shown in FIGS. 3 and 4, the slider 30 has a large ring portion 31 and a small ring portion 32 coaxially connecting the large ring portion 31 so that the cross-sectional shapes of the slider 30 at these two positions are both circular . The slider 30 has large and small ring portions 31 and 32 embedded in the large and small groove portions 23 and 24 of the sliding groove 22 respectively, so that the slider 30 can be displaced along the sliding groove 22 and blocked by the two end caps 25 Without falling out of the two ends of the chute 22.

The door closer 40 is buried in the accommodating groove 17 of the door panel 14 and is covered by a fixing piece 42. The fixing plate 42 is locked to the door plate 14 by a fixing element 43 such as a screw. The door closer 40 has a transmission shaft 41. The top of the transmission shaft 41 passes through the fixing piece 42 and protrudes out of the receiving slot 17 of the door panel 14. When the transmission shaft 41 is rotated by an external force, the door closer 40 can be generated Resistance to provide cushioning effect. Since the door closer 40 is a conventional technology, in order to save space, other detailed structures and operating principles will not be repeated here.

The main arm 50 is made of metal material. One end of the main arm 50 is pivotally connected to the slider 24. More specifically, one end of the main arm 50 has a convex shaft 51. As shown in FIG. 4, the convex shaft 51 has a large shaft portion 52 and a large shaft portion 52 coaxially connected The small shaft portion 53, the large shaft portion 51, and the small shaft portions 52, 53 are sleeved by the large and small ring portions 31, 32 of the slider 30, respectively, so that the slider 30 can rotate arbitrarily with respect to the convex shaft 51 to form a pivot Access effect. In addition, the other end of the main arm 50 has a rectangular hole 54, and the main arm 50 uses the rectangular hole 54 to snap to the top of the transmission shaft 41 of the door closer 40, so that the main arm 50 pulls the slider during the opening or closing of the door panel 14 24 moves in the chute 22, and at the same time drives the drive shaft 41 of the door closer 40, so that the door closer 40 provides a cushioning effect and allows the door panel 14 to operate stably.

As can be seen from the above, the slider 30 provided by the door closer assembly 10 of the present invention is presented in the form of a circular cross-section, and the appearance is more rounded and without edges, so that the slider 30 can effectively reduce the The friction between them can eliminate the abnormal sound and improve the smoothness of the operation, and further make the door panel 14 smoother and more stable in the process of opening and closing. It is also worth mentioning that there are many ways to install the slide rail 20 to the door frame 11 and the door closer 40 to the door panel 14, which is only one of them, because how to install the slide rail 20 and the door closer 40 is not the case The focus of this article will not repeat the other possible installation methods here.
