Description

Concealed glass door hinge with temporary positioning of opening angle

This creation relates to a hinge, especially a hidden glass door hinge with the function of temporarily positioning the opening angle.

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, so that the appearance of the door panel and door frame is relatively flat and beautiful, and it is less likely to be damaged by collision. Therefore, for the sake of beauty and durability, hidden hinges are usually used in decoration.

However, hidden hinges can only allow the door panel to pivot freely relative to the door frame, but cannot temporarily fix the door panel at a specific pivot angle; that is, a strong magnetic door stop must be used or if no force is applied to the door panel or other items are used As a stopper, the door panel will pivot and shake relative to the door frame at will, and may be forced to close due to wind blowing, resulting in inconvenience when people file in and out or carry items in and out, and may even pinch people or be damaged by collision.

Also, please refer to FIG. 15 , if the consumer uses the more economical exposed hydraulic door closer to install the positioning assembly 90 , because the more economical exposed hydraulic door closer is installed with the positioning assembly 90 , the exposed surface is used. Therefore, the installation method completely exposes the glass door panel and the door frame, and is likely to be damaged by collision with the wall, and eventually the door panel will be stuck, or the glass door panel may be cracked due to the impact, so it is less durable and unsafe.

Alternatively, please refer to FIG. 16, if you want to install the existing hidden hydraulic door closer installation positioning assembly 91 on the door panel, and the hidden hydraulic door closer installation positioning assembly 91 currently circulating on the market must be installed on the door frame. Outside the elongated slot 92 at the upper end, when the positioning angle is fixed, there must be a brace 93 exposed to support the door panel and the upper door frame. Therefore, the struts 93 are bound to be exposed on the door frame, which not only destroys the originally intended flat appearance, but also may easily damage the strength of the door frame because the elongated slot 92 is opened at the upper end of the door frame. In addition, due to the frequent damage rate of the positioning assembly 91 installed on the concealed hydraulic door closers currently on the market, unnecessary troubles are caused to consumers.

If the door panel is a glass door panel, there is also a problem of inability to locate the hidden hinges currently on the market. Therefore, if the glass door panel needs to solve the positioning problem, the following options are usually used. The first option: add positioning components to the exposed hydraulic door closer. The second option: the hidden hydraulic door closer is equipped with a positioning component. The third option: hydraulic ground hinge.

The exposed hydraulic door closer is equipped with a positioning assembly and the hidden hydraulic door closer is equipped with a positioning assembly. This is because the thickness of the glass door panel is usually thin, and the exposed hydraulic door closer and the hidden hydraulic door closer are thicker. When installing the exposed hydraulic door closer on the glass door panel, install the positioning component or the hidden hydraulic door closer. When adding positioning components to the device, 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, There must be a strut 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 with bolts must be installed outdoors, and then the exposed hydraulic door closer or hidden The type hydraulic door closer is installed on the exposed glass surface with screws through the glass door panel and then fixed on the bolt at the outdoor end or a flat plate with bolts. Therefore, the exposed hydraulic door closer positioning assembly and the hidden hydraulic door closer The strut will inevitably be exposed on the door frame and glass door panel, destroying the original flat appearance, as shown in Figure 16.

Please refer to Figure 17, the hydraulic ground hinge 94 is another option for the glass door panel, but if the hydraulic ground hinge 94 is used, a rectangular hole needs to be tapped on the ground and then the hydraulic ground hinge 94 is buried below the ground, so the oil The ground hinge 94 is not only cumbersome to construct and difficult to install, but also because the basic thickness of the hydraulic ground hinge 94 is too thick, when the rectangular hole on the ground floor is dug out, the exposed steel bars between the floors are almost seen. 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.

To sum up, in order to completely solve the above problems and troubles and temporarily fix the door panel at a specific pivot angle on the premise of maintaining a flat appearance of the door panel, it is necessary to install a hidden hydraulic closing door on the existing hidden hinge. The installation of positioning components for the door closers and the installation of positioning components for exposed hydraulic door closers and the hydraulic ground hinges have been thoroughly improved and improved.

The base body 41 is fixed on the second base 20 and used to be embedded in the door frame A1. A connecting channel 411 and at least one positioning channel 412 are formed in the base body 41 . The connection channel 411 has an outer end (the cylindrical Back Check end) and an inner end (the cylindrical fixing screw end). The positioning channel 412 includes an inner end (cylindrical end) and an outer end (threaded end). The inner end communicates with the connection channel 411 in the radial direction of the connection channel 411 ; the outer end penetrates the seat body 41 in this embodiment, that is to say, the outer end forms an opening on the seat body 41 , but it can also be used in other embodiments. The seat body 41 is not penetrated.

The connecting rod 42 is movably disposed in the connecting channel 411 and includes a threaded connecting end 421 . The connecting rod 42 can be an inclined connecting rod, or can also be a straight cylindrical connecting rod. The connecting rod 42 is designed so that after the positioning is released, the positioning element can gradually reduce the frictional force on the hinge operation. The screw connection end 421 is located outside the connection channel 411 and is connected to the connection block 31 of the pivot assembly 30 . When the first base 10 and the second base 20 are relatively pivoted by the pivot assembly 30 , the connecting block 31 of the pivot assembly 30 drives the connecting rod 42 to move in the connecting channel 411 . At least one positioning groove 422 is formed on the annular wall surface of the connecting rod 42 . The positioning groove 422 is selectively located in the connecting channel 411 to face the inner end of the positioning channel 412 when the connecting rod 42 moves.

The positioning element 43 is movably provided in the positioning channel 412 . The adjusting screw 44 is screwed into the positioning channel 412 and can move along the positioning channel 412 by the relative rotation of the screw teeth. The elastic element 45 is disposed in the positioning channel 412 and pushes the positioning element 43 toward the inner end so that the positioning element 43 protrudes from the inner end and abuts against the annular wall surface of the connecting rod 42 . When the positioning groove 422 of the connecting rod 42 faces the inner end of the positioning channel 412 , the positioning element 43 is pushed by the elastic element 45 to protrude into the positioning groove 422 and be fixed in the positioning groove 422 , thereby preventing the connecting rod 42 from moving further. Since the connecting rod 42 is blocked by the positioning element 43 and cannot move further, the pivot assembly 30 connected with the connecting rod 42 is also restricted by the fixed connecting rod 42 , so that the first seat 41 cannot continue to be connected to the connecting rod 42 . The second base body 41 pivots relatively. In other words, as long as the first seat body 41 and the second seat body 41 are relatively pivoted to a certain angle, the positioning element 43 will be clamped in the positioning groove 422 to stop the connecting rod 42 from moving further, and stop The connecting block 31 moves relative to the second base 20 , so that the first base 10 and the second base 20 can no longer pivot relative to each other.

In addition, in this embodiment, the elastic element 45 abuts between the adjustment screw 44 and the positioning element 43 , whereby the adjustment screw 44 can move along the positioning channel 412 to adjust the elastic element 45 to push the positioning element 43 toward the inner end. Moreover, since the outer end of the positioning channel 412 passes through the base body 41 , the user can turn the adjusting screw 44 from the outer end of the positioning channel 412 to adjust the force of the positioning element 43 against the connecting rod 42 . However, in other embodiments, there may be no adjustment screw 44 , so that the elastic element 45 may abut against the outer end of the positioning channel 412 that does not penetrate through the base body 41 .

Please refer to FIG. 2 , FIG. 3 , and FIG. 9 further, in this embodiment, the screw thread connection end 421 of the connecting rod 42 is screwed to the connection block 31 of the pivot assembly 30 , and the screw thread connection end 421 of the connection rod 42 can Passing through the connecting block 31 , the connecting rod 42 can adjust the position relative to the pivot assembly 30 . In this way, after the connecting rod 42 is adjusted relative to the pivot assembly 30, the relative positions of the positioning groove 422 and the positioning channel 412 are also adjusted, so that the pivot assembly 30 moves the connecting rod 42 to the position where the positioning groove 422 is facing The moving distances required for the positioning channel 412 are different; in other words, the pivot assembly 30 will move the adjusted connecting rod 42 to its position after the first base 10 and the second base 20 are relatively pivoted to a different angle. The positioning groove 422 is facing the positioning channel 412, so that the positioning member 40 can be adjusted at a specific pivot angle by adjusting the relative position of the connecting rod 42 and the pivoting member 30 to make the first base 10 and the second base The seat 20 is temporarily unable to pivot relative to it.

In addition, in the present embodiment, an operation groove 423 is formed on the end surface of the screw connection end 421 , and the operation groove 423 is used for engaging with a hand-held tool. Specifically, the operating groove 423 can be a slot-shaped slot, a cross-shaped slot, or a hexagon socket hole, whereby the rotary connecting rod 42 can be operated through a slot screwdriver, a cross screwdriver, or a hexagon socket wrench, which is convenient for Adjust the relative positions of the connecting rod 42 and the pivot assembly 30 . In other words, the end face of the screw connection end 421 is formed with an operation groove 423 in the form of a slot, and is used for mutual fitting with a hand-held flat-blade screwdriver, or the end face of the screw connection end 421 is formed with an inner hexagonal hole. The operating groove 423 is used to engage with a hand-held Allen wrench tool.

Furthermore, in this embodiment, the number of at least one positioning channel 412 of the base body 41 is two, and the two positioning channels 412 are respectively connected to the connecting channel 411 on opposite sides of the connecting channel 411 in the radial direction. The number of the elastic elements 45 is two, and the two elastic elements 45 are respectively disposed in the two positioning channels 412 . The number of the positioning elements 43 is two, and the two positioning elements 43 are respectively disposed in the two positioning channels 412 and abut against opposite sides of the annular wall surface of the connecting rod 42 respectively. The number of the positioning grooves 422 of the connecting rod 42 is one, and the positioning groove 422 is a ring groove. Therefore, when the positioning groove 422 is facing the two positioning channels 412 , the two positioning elements 43 are pushed by the two elastic elements 45 to protrude and be locked. fixed in the positioning groove 422 . However, the above quantities are not limited to this, and at least one original copy is required.

More specifically, in this embodiment, each positioning element 43 is a sphere, each elastic element 45 is a compression spring, and the positioning groove 422 of the connecting rod 42 is on a section passing through and parallel to the axis of the connecting rod 42 In other words, in this embodiment, the positioning groove 422 is an arc-shaped groove and the positioning element 43 is clamped in the arc-shaped groove with a spherical surface, so that the positioning element 43 can be easily removed from the positioning Slot 422. However, in other embodiments, it is not limited to the above. For example, the positioning element 43 can be a cylinder with two inclined surfaces at the end, and the two opposite wall surfaces of the positioning groove 422 are both inclined surfaces matched with the cylinder. This can also achieve the same effect.

Please refer to FIGS. 3 , 10 , and 11 , in this embodiment, a step surface 4111 is formed in the connecting channel 411 , and a nut 51 is screwed on one end of the connecting rod 42 opposite to the screw thread connecting end 421 and is provided with There is a spacer 52 located between the nut 51 and the step surface 4111. When the pivot assembly 30 drives the connecting rod 42 to move in the connecting channel 411 , the nut 51 selectively abuts against the step surface 4111 via the washer 52 , thereby preventing the connecting rod 42 from moving further. Thereby, by adjusting the position of the nut 51 on the connecting rod 42, the maximum distance that the pivot assembly 30 can move the connecting rod 42 can be limited, so that the connecting block 31 can be limited relative to the second base during the pivoting process The maximum distance that the 20 can move, thereby limiting the maximum angle of the first base 10 and the second base 20 relative to pivot and unfold; and the washer 52 can reduce the noise when the nut 51 hits the step surface 4111 . The design of the nut 51 selectively abutting against the step surface 4111 via the washer 52 can prevent the positioning angle from being damaged due to the user's excessive pressing of the door panel to prevent damage to the door panel structure (ie, the Back Check function).

In addition, "the nut 51 abuts against the step surface 4111 to stop the connecting rod 42 from moving further" is different from "the positioning element 43 is locked in the positioning groove 422 to stop the connecting rod 42 from moving further", the details are as follows. The positioning element 43 is clamped in the positioning groove 422 by being pushed by the elastic element 45 , and the positioning element 43 and the positioning groove 422 abut against each other with a circular arc surface, so when a force greater than the elastic force of the elastic element 45 is applied , the positioning slot 422 can push the positioning element 43 through the arc surface to make it slide away and disengage from the positioning slot 422, thereby releasing the connecting rod 42 to allow it to move freely; and the matching between the positioning element 43 and the positioning slot 422 is in Both the opening and closing pivot directions can be temporarily positioned until a force greater than the elasticity of the elastic element 45 is applied. The cooperation between the nut 51 and the step surface 4111 can only stop and continue to pivot in the pivoting direction when opening, and when the nut 51 and the step surface 4111 abut against each other, even if the force is pushed again The two cannot be slid apart and disengaged from each other and continue to pivot toward the pivoting direction when they are opened.

Please refer to FIG. 6 and FIG. 9 , when the glass door panel A2 is closed, that is, when the glass door panel A2 and the door frame A1 are pivoted by 0 degrees relative to each other, the connecting block 31 of the pivot assembly 30 has not yet pulled the connecting rod 42 toward the second base 20, At this time, the positioning element 43 abuts against the annular wall surface of the connecting rod 42 . 7 and 10 , when the pivoting angle θ of the glass door panel A2 relative to the door frame A1 is 27 degrees, that is, when the glass door panel A2 is opened 27 degrees relative to the door frame A1, the connecting block 31 of the pivot assembly 30 faces toward The second base 20 pulls the connecting rod 42 so that the positioning groove 422 of the connecting rod 42 faces the positioning channel 412 of the base body 41 during the process. At this time, the positioning element 43 is pushed by the elastic element 45 to protrude and be fixed in the positioning groove In 422, the connecting rod 42 can be temporarily stopped from continuing to move, so that the glass door panel A2 can be positioned at a position of opening 27 degrees relative to the door frame A1. Until the external force exerts a force greater than the elastic element 45 on the glass door panel A2 to lock the positioning element 43 in the positioning groove 422, it can abut the curved surface between the positioning groove 423 and the positioning element 43, and the elastic The element 45 pushes against the positioning element 43 and compresses the elastic element 45 to finally disengage the positioning element 43 from the positioning groove, thereby enabling the glass door panel A2 to pivot relative to the door frame A1 again.

The first base 10 and the second base can be adjusted when the positioning groove 422 is facing the positioning channel 412 if the connecting rod 42 is rotated through the operating groove 423 to move relative to the connecting block 31 of the pivot assembly 30 through the thread The relative pivoting angle between the When the glass door panel A1 is pivoted to an angle less than 27 degrees, the positioning groove 422 is already facing the positioning channel 412 and is locked by the positioning element 43, that is to say, the positioning angle is advanced to the angle less than 27 degrees, and The positioning angle can be determined by the facing position between the connecting block 31 and the connecting rod 42 .

8 and 11, when the glass door panel A2 continues to be opened to 90 degrees, the nut 51 abuts against the step surface 4111 via the gasket 52, so the glass door panel A2 cannot be further opened to a larger pivoting angle, However, the maximum opening angle of the glass door panel A2 can be further adjusted by adjusting the position of the nut 51 and the washer 52 on the connecting rod 42; It can be opened to more than 90 degrees relative to the door frame A1. On the contrary, if the nut 51 is rotated to move it to the left, the glass door panel A2 will be restricted by the nut 51 and the level surface 4111 before it opens to 90 degrees and cannot continue to face each other. Pivot to open on door frame A1.

12 , when the first base 10 and the second base 20 are relatively pivoted until the glass door panel A2 and the door frame A1 are at 90 degrees, the two pivoting parts 18 of the first base 10 drive the pivoting assembly The two rods 32 of the 30 move relative to the second base 20 , and the two sleeves 35 press against the abutting planes 211 of the two positioning protrusions 21 of the second base 20 respectively as the two rods 32 move. , whereby the two positioning protrusions 21 are clamped and fixed to the two tooth rods 32 through the two sleeves 35, and the connecting block is stopped from moving relative to the second base 20, so that the first base 10 and the second base 20 can no longer be moved. relative pivot. That is to say, when the glass door panel A2 is opened to 90 degrees, the two positioning protrusions 21 of the second base 20 will temporarily press against the two sleeves 35, so as to temporarily fix the glass door panel A2 at the opened 90 degree position. The user needs to exert force to push the glass door panel A2 again to pivot in the closing direction; in other words, in this embodiment, the glass door panel A2 can be temporarily fixed at 90 degrees open (by pressing the locking sleeve 35 through the positioning protrusion 21 ). ), and can also be temporarily fixed at a selected opening angle (by adjusting the relative position of the connecting rod 42 and the connecting block 31, the positioning element 43 can be locked in the positioning groove 422 at the selected opening angle).

The advantage of the present invention lies in that the connecting rod 42 is disposed in the connecting channel 411 of the base body 41 and has a positioning groove 422 that can face the positioning channel 412 during the movement process, and the positioning element 43 is disposed in the positioning channel 412 and is elastically The element 45 pushes against the connecting rod 42 . When the connecting rod 42 moves until the positioning groove 422 faces the positioning channel 412 , the positioning element 43 can be locked in the positioning groove 422 to stop the connecting piece from continuing to move. Therefore, by further adding the positioning component 40, the base body 41 is fixed on the second base 20, and the connecting rod 42 is connected to the pivot component 30. When the first base 10 and the second base 20 are connected by When the pivot assembly 30 is relatively pivoted, the pivot assembly 30 drives the connecting rod 42 to move in the connecting channel 411 , and selectively causes the positioning groove 422 to face the positioning channel 412 . When the positioning groove 422 of the connecting rod 42 is facing the positioning channel 412 , the positioning element 43 will be pushed by the elastic element 45 to protrude into the positioning groove 422 and be fixed in the positioning groove 422 , thereby preventing the connecting rod 42 from moving further. The first base 10 and the second base 20 can no longer pivot relative to each other. In this way, the first base 10 can be connected to the glass door panel A2, the second base 20 and the positioning element 40 can be embedded in the door frame A1, and the first base 10 and the first base 10 and the first base 10 can be fixed at a specific angle through the positioning element 40. The two bases 20 can temporarily fix the glass door panel A2 at a specific pivot angle without protruding from the door frame A1, which not only maintains a flat appearance, but also is less likely to be damaged by collision, so it is more sturdy and durable.
