Adjustable door closer

This creation is related to the door closer, especially an adjustable door closer that can be used with the weight of the door panel.

When the door panel of a general building is opened or closed, in order to prevent the door panel from being damaged due to excessive impact force, a common solution is to install a door closer between the door panel and the door frame, and on the other hand, the door panel is opened or closed. The middle can be stably operated, and on the other hand, the door panel can be positioned after being opened.

However, the resistance and positioning effect provided by a single door closer does not have the ability to meet the door panels of different weights, so that it is necessary to design a corresponding door closer for the weight of the door panel, which will result in cost for the manufacturer. The increase is not economical.

The main purpose of this creation is to provide an adjustable door closer that can adjust the tightness of the opening and positioning with the door panels of different weights to increase the flexibility of use.

The sliding rail is disposed in a door frame; the brake unit has a spring fixing seat, a spring piece, a adjusting piece, and a positioning component, wherein the elastic piece fixing seat is disposed in the sliding rail and has two opposite vertical walls. One end of the elastic piece is fixed to the elastic piece fixing seat, and the other end of the elastic piece has a braking portion. Further, the elastic piece has a long slot hole near the center, and one end of the adjusting piece has a pressing portion, and the adjusting piece has a pressing portion. The other end has two opposite extending arms, and the adjusting piece is pressed against the top surface of the braking portion of the elastic piece by the pressing portion, and the adjusting piece abuts against the vertical wall of the elastic piece fixing seat by the two extending arms The inner wall surface, in addition, the adjusting piece has a positioning hole between the pressing portion and the two extending arms, the positioning member passes through the long slot of the elastic piece and is fixed in the positioning hole of the adjusting piece, the connection One end of the arm is connected to a door panel, and the other end of the arm is connected to the slider, and the slider is slidably disposed in the sliding rail, so that the slider can be engaged or disengaged by the driving of the connecting arm In the braking part of the shrapnel. It can be seen from the above that the adjustable door closer of the present invention can change the distance between the adjusting piece and the braking portion of the elastic piece through the positioning member, thereby further adjusting the tightness of the door panel with different weights being opened and positioned.

In the embodiment of the present invention, the slide rail has a plurality of first perforations arranged at intervals, and the spring mount has a bottom wall connecting the two vertical walls, the bottom wall has a first screw hole, and the slide rail and the slide rail The first fixing screws are respectively disposed in the first screw holes of the elastic piece fixing seat and are selectively disposed on one of the first through holes of the sliding rails. Therefore, the opening angle of the door panel can be further adjusted by adjusting the installation position of the slide rail in the door frame.

In the embodiment of the present invention, the bottom wall of the elastic piece fixing seat has a second through hole, and one end of the elastic piece has a second screw hole, and the elastic piece fixing seat and the elastic piece are fixed together by a second fixing screw. The second fixing screw passes through the second through hole of the elastic piece fixing seat and is screwed into the second screw hole of the elastic piece. Further, one end of the adjusting piece has a notch, and the notch is connected to the elastic piece fixing seat. The second fixing screw is disposed on the second fixing screw to avoid interference between the adjusting piece and the second fixing screw.

Please refer to FIG. 1 . The adjustable door closer 20 of the present invention is mainly used with a door frame 10 and a door panel 12 pivoted on the door frame 10, and then please refer to FIG. 2, the adjustable door closer 20 of the present invention. A slide rail 30, a brake unit 40, a link arm 50, and a slider 60 are included.

The slide rail 30 is fixed in the door frame 10 and has a plurality of first perforations 32 arranged at intervals.

Referring to FIGS. 2 and 3, the brake unit 40 has a spring fixing base 41, a spring piece 42, a adjusting piece 43, and a positioning member 44. The elastic plate fixing base 41 has two opposite vertical walls 411 and a bottom wall 413 connecting the two vertical walls 411. One end of the bottom wall 413 has a first screw hole 412, and the other end of the bottom wall 413 has a second through hole 414. The seat 41 is fixed to the slide rail 30 by a first fixing screw 45. The first fixing screw 45 is screwed into the first screw hole 412 of the bottom wall 413 of the elastic piece fixing base 41 and is selectively disposed on the slide rail 30. The first end of the elastic piece 42 has a braking portion 422. The other end of the elastic piece 42 has a second screw hole 424. The elastic piece 42 is fixed to the elastic piece fixing seat 41 by a second fixing screw 46, and the second fixing screw The second through hole 414 of the elastic piece fixing portion 41 is screwed into the second screw hole 424 of the elastic piece 42. Further, the elastic piece 42 has a long slot hole 426 near the second screw hole 424; the adjusting piece 43 One end has two opposite extending arms 431 and a notch 432 between the two extending arms, wherein the outer surface of the extending arm 431 has an outer convex portion 433, and the other end of the adjusting piece 43 has a pressing portion 434. Moreover, the center of the adjusting piece 43 has a certain relationship between the extending arm 431 and the pressing portion 434. The positioning hole 44 is inserted into the positioning hole 436 of the adjusting piece 43 for assembling and fixing the adjusting piece 43 and the elastic piece 42 together. After the assembly is completed, the positioning piece is adjusted. The protrusion 433 of the second extension arm 431 abuts against the inner wall surface of the vertical wall 411 of the elastic piece fixing base 41 to prevent the yoke 43 from being yawed during the adjustment process, thereby improving the actuation stability. When the notch 432 is sleeved on the second fixing screw 46, mutual interference with the second fixing screw 46 is avoided, and the adjusting piece 43 presses the braking portion 422 of the elastic piece 42 by the pressing portion 434.

One end of the link arm 50 is fixed to the door panel 12 so that the link arm 50 can be actuated in synchronization with the opening or closing of the door panel 12.

The slider 60 is slidably disposed in the slide rail 30 and has a slot 62 and a third screw hole 64 of the communication slot 62. The other end of the slider 60 and the link arm 50 is supported by a third fixing screw 66. The third fixing screw 64 is inserted through one end hole of the connecting arm 52 and screwed into the third screw hole 64 of the slider 60 to enable the slider 60 to be driven by the connecting arm 50.

It can be seen from the above structure that when the door panel 12 is opened by an external force, the connecting arm 50 is driven by the door panel 12 to pull the slider 60 to move in the sliding rail 30, so that the slider 60 presses the braking portion 422 of the elastic piece 42 until the elastic piece 42 The braking portion 422 is snapped into the slot 62 of the slider 60 (as shown in FIG. 3), and the door panel 12 is now positioned. Conversely, when the door panel 12 is to be closed, the external force received by the door panel 12 must be It is sufficient to force the card slot 62 of the slider 60 to disengage from the braking portion 422 of the spring piece 42. Once the two are separated from each other, as shown in Fig. 3, the door panel 12 is gradually closed.

To adjust the tightness of the positioning of the door panel 12 after opening, the positioning member 44 is first loosened by a hand tool (such as a hex wrench) to move the position of the positioning member 44 in the long slot 426 when the positioning member 44 moves to the long position. When the right end of the slot 426 is at the right end, as shown in FIG. 5, the distance between the pressing portion 434 of the adjusting piece 43 and the braking portion 422 of the elastic piece 42 is relatively short, so that the braking portion 422 of the elastic piece 42 is relatively inelastic, so that As for the relatively large force between the card slot 62 of the slider 60 and the braking portion 422 of the elastic piece 42 to be able to be snapped or detached from each other, the configuration at this time is suitable for the heavy weight door panel 12, and conversely, if the positioning member is to be When moving to the left end of the long slot 426, as shown in Fig. 6, the distance between the pressing portion 434 of the tab 43 and the braking portion 422 of the elastic piece 42 is relatively long, so that the braking portion 422 of the elastic piece 42 is compared. With the elasticity, the card slot 62 of the slider 60 and the braking portion 422 of the elastic piece 42 can be engaged or disengaged from each other without much force. The configuration at this time is suitable for the light weight door panel 12.

On the other hand, if the opening angle of the door panel 12 is to be changed, the first fixing screw 45 is first loosened, then the braking unit 40 is moved by the position of the first through hole 32 of the sliding rail 30, and the first fixing screw 45 is locked. In the corresponding first through hole 32, the opening angle of the door panel 12 can be easily changed.

In summary, the adjustable door closer 10 of the present invention can change the position of the adjusting piece 43 according to different actual needs, so that the door panels of different weights can adjust the tightness of the opened positioning according to actual needs, so as to increase the elasticity of use. purpose.
