Description

Hidden glass door hinge with temporary positioning function of opening angle

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

The concealed hinge can be hidden in the door frame and the door panel when the door panel is closed, so as not to protrude from the wall, the appearance of the door panel and the door frame can be smoother and more beautiful, and it is less likely to be damaged by collision. Therefore, if it is for beauty and durability, hidden hinges are usually used for 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 objects are not used As a stop, the door panel will randomly pivot and swing relative to the door frame, and may be closed vigorously due to wind, which may cause inconvenience when many people file in and out or carry items in and out, and may even pinch people or damage it by collision.

Also, please refer to Figure 15. If consumers use a more economical exposed hydraulic door closer with a positioning assembly 90, the more economical exposed hydraulic door closer is equipped with a positioning assembly 90, which uses an exposed surface. Therefore, the installation method completely exposes the glass door panel and the door frame and is likely to be damaged by the wall collision, and eventually jam the door panel, or the glass door panel is cracked due to the impact, so it is less durable and unsafe.

Or, please refer to Figure 16. If you want to install the existing concealed hydraulic door closer with the positioning assembly 91 on the door panel, and the concealed hydraulic door closer currently on the market is installed with the positioning assembly 91, you must install the positioning assembly 91 of the door frame. A long slot 92 is opened at the upper end. When the positioning angle is fixed, a support rod 93 must be exposed to support the door panel and the upper door frame. Therefore, the strut 93 will inevitably be exposed to the door frame. In addition to destroying the originally intended flat appearance, the elongated slot 92 at the upper end of the door frame may easily damage the strength of the door frame. Moreover, the frequent damage rate of the locating assembly 91 installed on the hidden hydraulic door closers currently on the market causes unnecessary trouble for consumers.

If the door panel is a glass door panel, using the hidden hinges currently on the market also has the problem of not being able to be positioned. 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: add positioning components to the hidden hydraulic door closer. The third option: hydraulic floor hinge.

The exposed hydraulic door closer is equipped with positioning components and the hidden hydraulic door closer is equipped with positioning components. Because the thickness of the glass door panel is usually thin, the exposed oil pressure door closer and the hidden oil pressure door closer are thicker, when the exposed oil pressure door closer is installed on the glass door panel, the positioning component or the hidden oil pressure door closer When installing positioning components on the glass door, you must first open two or more round holes on the surface of the glass door, and you must install more than two bolts or a plate with bolts outdoors. When fixing the positioning angle, There must be a brace 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 plate with bolts must be installed outdoors, and then the exposed hydraulic door closer or hidden Type hydraulic door closers are installed on the exposed glass surface with screws penetrating the glass door panel and then fixed on the bolts at the outdoor end or a plate with bolts. Therefore, the positioning components of the exposed hydraulic door closers and the hidden hydraulic door closers The struts will inevitably be exposed on the door frame and glass door panel, destroying the originally intended flat appearance, as shown in Figure 16.

Please refer to Figure 17, the hydraulic floor hinge 94 is another choice for glass door panels, but if the hydraulic floor hinge 94 is used, a rectangular hole needs to be punched in the ground and then the hydraulic floor hinge 94 is buried below the ground. The floor hinge 94 is not only cumbersome to construct and difficult to install, but also because the basic thickness of the hydraulic floor hinge 94 is too thick, often when the rectangular hole on the ground floor is excavated, the bare steel bars between the floors are almost seen. Therefore, it not only destroys the floor building structure, destroys the beauty of the ground, but also causes difficulties in subsequent maintenance and the inability to restore the level of the ground.

In summary, in order to completely solve the above-mentioned problems and troubles and to temporarily fix the door panel at a specific pivot angle while maintaining the flat appearance of the door panel, it is necessary to add a hidden hydraulic closing door to the existing hidden hinge The positioning components and the exposed hydraulic door closers are installed with positioning components and hydraulic hinges, which are completely improved and improved.

However, the specific structure of the first base 10 connected to the glass door panel A2 is not limited to the above. For example, please refer to FIG. 13 and FIG. 14. In other embodiments, the first base 10A may also have three pressure resistances without screws. The screw 16A and the pressing piece 15A can also have three pressing grooves 151A, so that the three pressing screws 16A respectively abut against the three pressing grooves 151A of the pressing piece 15A, and the three pressing screws 16A all face the front door panel The fixing portion 11A pushes against the abutment piece 15A. That is to say, in the embodiments of FIGS. 13 and 14, it is not necessary to perforate the glass door panel A2, so as to avoid reducing the structural strength of the glass door panel A2.

Please refer to FIG. 3, FIG. 6, and FIG. 12, the second base 20 is used to be buried in the door frame A1. Specifically, in this embodiment, the second base 20 includes two positioning protrusions 21, and each positioning protrusion 21 has an abutting plane 211.

Please further refer to FIGS. 3 and 4, the pivot assembly 30 is connected to the first base 10 and the second base 20, and the first base 10 and the second base 20 can be relatively pivoted by the pivot assembly 30. The pivot assembly 30 includes a connecting block 31 located in the second base 20, and when the first base 10 and the second base 20 are relatively pivoted, the connecting block 31 will be relative to the second base during the pivoting process. The second base 20 moves.

Specifically, in this embodiment, the pivotal assembly 30 further includes two tooth rods 32, two sliding blocks 33, two pivotal members 34, and two sleeves 35, and the first base 10 further includes two pivotal portions 18. The aforementioned connecting block 31 is sandwiched between the two pivoting parts 18, and the two pivoting parts 18 extend into the second base 20 from the front side opening of the second base 20. The two sliding blocks 33 are respectively inserted into the upper sliding groove and the lower groove of the second base 20 from the opening of the upper and lower groove on the rear side of the second base 20. The two tooth rods 32 are respectively inserted into the second base 20 through two holes on the top and bottom sides of the second base 20, and the upper tooth rod 32 first penetrates the upper slider 33 and then penetrates the upper pivot part 18 , And finally screw down to the connecting block 31; and the lower tooth rod 32 first penetrates the lower sliding block 33 and then the lower pivot part 18, and finally screw up to the connecting block 31. That is to say, the two tooth rods 32 are respectively screwed on both sides of the connecting block 31, whereby when the first base 10 and the second base 20 are relatively pivoted, the two pivoting parts 18 of the first base 10 will meet The two tooth rods 32 and the connecting block 31 are driven to move relative to the second base 20. Two ends of each pivoting member 34 are pivoted on the first base 10 and the second base 20 respectively, so that the first base 10 and the second base 20 can be relatively pivoted through the two pivoting members 34. The two sleeves 35 are respectively sleeved on the two tooth rods 32.

Please further refer to FIGS. 3, 9 and 10, the positioning assembly 40 includes a base 41, a connecting rod 42, at least one positioning element 43, at least one adjusting screw 44, and at least one elastic element 45.

The seat body 41 is fixed on the second base 20 and used to be buried in the door frame A1. A connecting channel 411 and at least one positioning channel 412 are formed in the base 41. The connecting 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 (cylinder end) and an outer end (thread end). The inner end is connected to the connecting channel 411 in the radial direction of the connecting 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 Does not penetrate the seat body 41.

The connecting rod 42 is movably disposed in the connecting channel 411 and includes a screw connection end 421. The connecting rod 42 may be an inclined connecting rod or a straight cylindrical connecting rod. The design of the connecting rod 42 enables the positioning element to gradually reduce the frictional force on the operation of the hinge after the positioning is released. The screw connection end 421 is located outside the connection channel 411 and 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 of the connecting rod 42, and the positioning groove 422 is selectively located in the connecting channel 411 opposite to the inner end of the positioning channel 412 by the movement of the connecting rod 42.

The positioning element 43 is movably arranged 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 relative rotation of the screw thread. 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 is facing the inner end of the positioning channel 412, the positioning element 43 is pushed by the elastic element 45 to protrude and be locked in the positioning groove 422, thereby preventing the connecting rod 42 from moving further. Since the connecting rod 42 is stopped by the positioning element 43 and cannot move further, the pivotal assembly 30 connected to the connecting rod 42 will also be restricted by the fixed connecting rod 42 and cannot continue to connect the first seat 41 with The second seat 41 pivots relatively. In other words, as long as the first seat 41 and the second seat 41 are relatively pivoted to a specific angle, the positioning element 43 will be locked 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 adjusting screw 44 and the positioning element 43, whereby the adjusting 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 penetrates the seat 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, the adjusting screw 44 may not be provided. In this case, the elastic element 45 may be abutted against the outer end of the positioning channel 412 that does not penetrate the seat body 41.

Please further refer to FIGS. 2, 3, and 9, in this embodiment, the screw connection end 421 of the connecting rod 42 is screwed to the connecting block 31 of the pivot assembly 30, and the screw connection end 421 of the connecting rod 42 can be Through the connecting block 31, the connecting rod 42 can adjust the position relative to the pivot assembly 30. In this way, when the connecting rod 42 is adjusted relative to the pivot assembly 30, the relative position of the positioning slot 422 and the positioning channel 412 will also be adjusted, so that the pivot assembly 30 moves the connecting rod 42 to the positioning slot 422. The moving distance required for the positioning channel 412 is different; in other words, the pivot assembly 30 will move the adjusted connecting rod 42 to a different angle 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 by adjusting the relative position of the connecting rod 42 and the pivot assembly 30, the positioning assembly 40 can be adjusted at a specific pivot angle so that the first base 10 and the second base 10 The seat 20 cannot be relatively pivoted temporarily.

In addition, in this embodiment, an operating groove 423 is formed on the end surface of the screw thread connecting end 421, and the operating groove 423 is used to engage with a hand-held tool. Specifically, the operating groove 423 may be a straight slot, a cross-shaped slot, or an inner hexagon hole, whereby the rotating connecting rod 42 can be operated through a straight screwdriver, a cross screwdriver, or an inner hexagon wrench, respectively, which can facilitate The relative position of the connecting rod 42 and the pivot assembly 30 is adjusted. In other words, the end surface of the screw connection end 421 is formed with an operating groove 423 in the form of a straight groove, and is used to engage with a hand-held flat-head screwdriver tool, or the end surface of the screw connection end 421 is formed with an inner hexagonal hole. The operation groove 423 is used for mutual engagement with a hand-held hexagon wrench tool.

Furthermore, in this embodiment, the number of at least one positioning passage 412 of the seat body 41 is two, and the two positioning passages 412 are respectively connected to the connecting passage 411 on opposite sides of the connecting passage 411 in the radial direction. The number of the elastic elements 45 is two, and the two elastic elements 45 are respectively arranged in the two positioning channels 412. The number of the positioning elements 43 is two, and the two positioning elements 43 are respectively arranged in the two positioning channels 412 and respectively abut on opposite sides of the ring wall surface of the connecting rod 42. The number of the positioning groove 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 passages 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. But the above quantity is not limited to this, at least only the quantity of each original is required to be one.

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 cross section that passes through and is parallel to the axis of the connecting rod 42. It is a circular arc line; that is, in this embodiment, the positioning groove 422 is an arc-shaped groove and the positioning element 43 is fixed in the arc-shaped groove with a spherical surface, thereby facilitating the positioning element 43 to be separated from the positioning Slot 422. However, in other embodiments, it is not limited to the above. For example, the positioning element 43 may be a column with two inclined surfaces at the end, and the two opposite wall surfaces of the positioning groove 422 are both inclined surfaces that match the column. This can also achieve the same effect.

3, 10, and 11, in this embodiment, a step surface 4111 is formed in the connecting channel 411, and the connecting rod 42 is screwed on one end of the connecting end 421 with respect to the screw thread, and a nut 51 is provided. There is a washer 52, which is located between the nut 51 and the step surface 4111. When the pivotal 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, and thereby stops the connecting rod 42 from further moving. Thereby, the maximum distance that the pivotal assembly 30 can move the connecting rod 42 can be restricted by adjusting the position of the nut 51 on the connecting rod 42, so as to restrict the connecting block 31 relative to the second base during the pivoting process. The maximum distance that 20 can move, in turn, can limit the maximum angle at which the first base 10 and the second base 20 are relatively pivoted and expanded; and the spacer 52 can reduce the sound of the nut 51 hitting the step surface 4111. The design of the nut 51 selectively abutting the step surface 4111 via the gasket 52 can prevent the positioning angle because the user excessively pushes the door panel to prevent damage to the door panel structure (ie, Back Check function).

In addition, "the nut 51 abuts against the step surface 4111 to stop the connecting rod 42 from further moving" is different from "the positioning element 43 is locked in the positioning groove 422 to stop the connecting rod 42 from moving further", and the details are as follows. The positioning element 43 is pushed by the elastic element 45 to be clamped in the positioning groove 422, and the positioning element 43 and the positioning groove 422 are pressed against each other by an arc surface, so when a force greater than the elastic force of the elastic element 45 is applied , The positioning groove 422 can push the positioning element 43 through the arc-shaped surface to make it slide and escape from the positioning groove 422, thereby releasing the connecting rod 42 so that it can move freely; and the positioning element 43 and the positioning groove 422 are matched Both the opening and closing pivoting directions can be temporarily positioned to be applied with a force greater than the elasticity of the elastic element 45. The cooperation of the nut 51 and the step surface 4111 is that it can only 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 it is pushed again. The two cannot be relatively slid apart and continue to pivot in the pivoting direction when opening.

6 and 9, when the glass door panel A2 is closed, that is, when the glass door panel A2 and the door frame A1 are relatively pivoted by 0 degrees, the connecting block 31 of the pivotal 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 pivotal assembly 30 faces The second base 20 pulls the connecting rod 42 so that the positioning groove 422 of the connecting rod 42 is aligned with the positioning channel 412 of the seat body 41. At this time, the positioning element 43 is pushed by the elastic element 45 and protrudes into the positioning groove. In 422, the continuous movement of the connecting rod 42 can be temporarily stopped by this, so that the glass door panel A2 can be positioned at an opening position of 27 degrees with respect 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, the positioning element 43 can be pressed against 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.

Wherein, 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 positioning groove 422 can be adjusted when the first base 10 and the second base are facing the positioning channel 412. The relative pivot angle between 20; specifically, compared to the state in FIG. 10, the connecting rod 42 moves toward the second base 20, so that the positioning groove 422 also moves toward the second base 20, so when the door frame A2 When pivoting to an angle less than 27 degrees relative to the glass door panel A1, the positioning groove 422 is already directly facing the positioning channel 412 and is clamped 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.

Please continue to refer to Figures 8 and 11, when the glass door panel A2 continues to open to 90 degrees, the nut 51 abuts against the step surface 4111 via the spacer 52, so the glass door panel A2 cannot be opened further to a larger pivot angle. However, the maximum opening angle of the glass door panel A2 can be further adjusted by adjusting the positions of the nut 51 and the washer 52 on the connecting rod 42; for example, rotating the nut 51 to move it to the right in FIG. It can be opened to greater than 90 degrees relative to the door frame A1. On the contrary, if the screw cap 51 is rotated to move it to the left, the glass door panel A2 will be restricted by the screw cap 51 and the level surface 4111 before being opened to 90 degrees and cannot continue to face each other. Pivot to open the door frame A1.

And, please further refer to FIG. 12, when the first base 10 and the second base 20 are relatively pivoted so that the glass door panel A2 and the door frame A1 are 90 degrees, the two pivot parts 18 of the first base 10 drive the pivot assembly The two tooth rods 32 of 30 move relative to the second base 20, and the two sleeves 35, as the two tooth rods 32 move, respectively tightly abut against the abutting planes 211 of the two positioning protrusions 21 of the second base 20 Therefore, the two positioning protrusions 21 fix the two tooth rods 32 through the two sleeves 35, and stop the connecting block 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 pivoting. In other words, when the glass door panel A2 is opened to 90 degrees, the two positioning protrusions 21 of the second base 20 will temporarily abut and clamp the two sleeves 35, so as to temporarily fix the glass door panel A2 at the opened position of 90 degrees. The user needs to apply force to push the glass door A2 again to pivot in the closed direction; in other words, in this embodiment, the glass door A2 can be temporarily fixed at 90 degrees of opening (through the positioning protrusion 21 to press the clamping sleeve 35 ), 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, so that the positioning element 43 is locked in the positioning slot 422 at the selected opening angle).

The advantage of the present invention is that the connecting rod 42 is arranged in the connecting channel 411 of the base 41 and has a positioning groove 422 which can face the positioning channel 412 during the movement, and the positioning element 43 is arranged in the positioning channel 412 and is elastic The element 45 is pushed toward the connecting rod 42. When the connecting rod 42 moves until the positioning groove 422 is facing the positioning channel 412, the positioning element 43 can be locked in the positioning groove 422 to stop the connecting piece from moving. Therefore, by further adding the positioning assembly 40, the base 41 is fixed to the second base 20, and the connecting rod 42 is connected to the pivot assembly 30, when the first base 10 and the second base 20 pass through When the pivot assembly 30 relatively pivots, the pivot assembly 30 will drive the connecting rod 42 to move in the connecting channel 411 and selectively make the positioning groove 422 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 and be locked in the positioning groove 422, and thereby stop the connecting rod 42 from moving further, thereby 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, and the second base 20 and the positioning assembly 40 can be buried in the door frame A1, and the first base 10 and the second base 10 can be fixed at a specific angle through the positioning assembly 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 and is less susceptible to damage due to collisions, so it is more robust and durable.
