Description

Concealed glass door hinge with adjustable average speed deceleration door closing function

This creation relates to a hinge, especially a hidden glass door hinge that has the function of automatically closing the door and can adjust the closing speed to reduce the closing speed in an average and stable manner and achieve smooth closing of the door.

The hidden hinge can be hidden in the door frame and the door panel when the door panel is closed, thereby not protruding from the wall surface, making the appearance more flat and beautiful, and less likely to be damaged by collision. Therefore, for the sake of beauty and durability, hidden hinges are usually used in decoration.

Referring to FIG. 17 , the conventional hidden hinge includes a first base 91 , a second base 92 , a pivot assembly 93 , and a reset assembly 94 . The first base 91 and the second base 92 are used to be embedded in the door frame and the door panel, respectively. The pivot assembly 93 connects the first base 91 and the second base 92 , whereby the first base 91 and the second base 92 can pivot relative to each other through the pivot assembly 93 . The reset assembly 94 includes a connecting rod 941 and an elastic element 942 . One end of the connecting rod 941 penetrates through the second base 92 and is connected to the pivot assembly 93 , and the other end forms an abutting portion. The elastic element 942 abuts between the second base 92 and the abutting portion of the connecting rod 941 .

When the door is opened, that is, when the first base 91 is pivoted relative to the second base 92 by the pivot assembly 93, the pivot assembly 93 will pull the connecting rod 941 to move relative to the second base 92, and The abutting portion of the connecting rod 941 moves toward the second base 92 to compress the elastic member 942 . Therefore, when the external force no longer exerts force on the door panel, the elastic element 942 pushes against the abutting portion of the connecting rod 941 to keep it away from the second base 92, and the connecting rod 941 pulls the pivot assembly 93 to make it move in the opposite direction. This makes the first base 91 and the second base 92 return to the state before the relative pivoting, so as to achieve the effect of automatic door closing.

Please refer to FIG. 17 and FIG. 18. In order to automatically close the door panel with a certain weight in the prior art, the elastic element 942 must have a considerable compressive elastic force, which will cause the immediate closing speed of the elastic element 942 to rebound and close the door too fast. Therefore, it is easy to pinch or collide with the human body. In addition, since the connecting rod 941 and the elastic element 942 are directly embedded in the accommodating groove further excavated in the door frame, the abutting part of the elastic element 942 and the connecting rod 941 will be slightly compressed after the elastic element is compressed during the door opening and closing process. Bending deformation may rub against the inner wall of the accommodating slot, especially when the door frame is a wooden door frame, the residual wood fiber rubs against the exposed elastic element 942 and generates noise, which may reduce the service life of the hinge, and the elastic element will last for a long time. Both the 942 and the door frame hinge will wear out, resulting in low durability, and because the elastic element 942 directly and instantly generates rebound force in the process of closing the door, it is likely to cause pinching or collision with the human body, causing unnecessary injuries. Human events occur.

In addition, there are three options on the market:

The first option, please refer to Figure 19, if the consumer uses the more economical exposed hydraulic door closer 960 to install the positioning assembly 961, then because the more economical exposed hydraulic door closer 960 is equipped with the positioning assembly 961, The system adopts the exposed surface installation method, so the door panel and door frame are completely exposed, and it is likely to be damaged by wall collision, and eventually the door panel will be stuck, so it is less sturdy and durable.

For the second option, please refer to FIG. 20. If you want to install the existing hidden hydraulic door closer 962 on the door panel, add the positioning assembly 963, and the hidden hydraulic door closer 962 currently circulating on the market is equipped with the positioning assembly For 963, you must first open more than two round holes on the surface of the glass door panel, and you must install more than two bolts or a flat plate with bolts outdoors. When fixing the positioning angle, you must have one. The struts 964 are exposed to support the glass door panel and the upper door frame. Therefore, in addition to the surface of the glass door, more than two round holes must be added, and more than two bolts or a flat plate 965 with bolts must be installed outdoors, and then the hidden hydraulic door closer 962. The exposed method uses screws to penetrate the glass door panel and then fix it on the bolt at the outdoor end or a flat plate with bolts. Therefore, the concealed hydraulic door closer 962 and the strut 964 must be exposed to the door frame and glass door panel. In addition to the flat appearance originally intended to be created, the fact that the hidden hydraulic door closers 962 currently on the market with the positioning components 963 are frequently damaged, causing unnecessary trouble for consumers.

Another third option, please refer to Figure 21, the hydraulic ground hinge 966 is another option, but if the hydraulic ground hinge 966 is used, it is necessary to knock a rectangular hole on the ground and then bury the hydraulic ground hinge 966 below the ground Therefore, the hydraulic ground hinge 966 is not only cumbersome to construct and difficult to install, but also because the basic thickness of the hydraulic ground hinge 966 is too thick. Therefore, it not only destroys the building structure of the floor, but also destroys the beauty of the ground, and causes subsequent maintenance difficulties and the inability to restore the smoothness of the ground.

The dish-shaped elastic elements 470 are located between the elastic element 47 and the front cover 42 ; With the disk-shaped elastic element 470 , when the door panel is opened close to 90 degrees, the elastic element bears more weight due to the force distance of the lever arm. Therefore, the disk-shaped elastic element 470 drives the door panel to instantly increase the closing elasticity of the elastic element 47 .

Because the connecting end 451 of the connecting rod 45 is located outside the front end 411 of the sleeve 41 and is connected to the pivot assembly 30, the pivot assembly 30 can drive the connecting rod 45 to move relative to the sleeve 41 and can move toward the sleeve through the connecting rod 45. The front end 411 of 41 moves the connecting piece 46, and the elastic element 47 is connected to the connecting piece 46 and tends to move the connecting piece 46 in the direction of the rear end 412 of the sleeve 41, when the user opens the door, the glass door panel A2 is pivoted relative to the door frame A1 During rotation, the first base 10 and the second base 20 are relatively pivoted by the pivot assembly 30, and the pivot assembly 30 will pull the connecting rod 45 and exert force on the elastic element 47 through the connecting member 46, and when the user After the door panel A2 is no longer applied, the elastic element 47 can move the connecting rod 45 toward the rear end 412 of the sleeve 41 through the connecting member 46, and move the pivot assembly 30 through the connecting rod 45, thereby making the first base The door 10 and the second base 20 are reset by the relative pivoting of the pivot assembly 30 to achieve automatic deceleration and a stable door closing effect at an average speed.

In addition, by adding the sleeve 41, two oil retaining rings 48 are sleeved on the outer ring surface of the connecting member 46, and the two oil retaining rings 48 are radially outwardly close to the inner annular surface of the sleeve 41, and the two The damping oil 49 is filled in the space enclosed by the oil protection ring 48 , the connecting piece 46 and the sleeve 41 . When the elastic element 47 drives the connecting piece 46 to move toward the rear end 412 of the sleeve 41 , the two oil protection rings 48 and the damping oil 49 are filled with damping oil 49 . The oil 49 will rub against the sleeve 41, so that the elastic element 47 can only move the connecting piece 46 slowly, so that the elastic element 47 can connect the first base 10 and the second base 20 through the connecting rod 45 and the pivot assembly 30. Slowly pivot and reset to achieve the effect of reducing the speed of automatic door closing, so it can avoid the door closing too fast and injuring people. In addition, by embedding the sleeve 41 in the door frame A1 and sheathing the elastic element 47, the connecting rod 45, and the connecting piece 46, the elastic element 47, the connecting rod 45, and the connecting piece 46 will all be in the door during the door opening and closing process. The sleeve 41 moves inside without rubbing against the door panel A2 or the door frame A1, so that the rubbing against the door frame A1 can be avoided, which not only reduces noise but also increases durability and safety.
