Description

Hidden hinge with temporary positioning function of opening angle

This creation relates to a hinge, especially a hidden hinge with the function of freely adjusting to achieve multiple angle positioning and suspension devices.

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.

And, please refer to Figure 9. 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 door panel and the door frame, and is likely to be damaged by the collision of the wall, and eventually jam the door panel, so it is not strong and durable.

Or, please refer to Figure 10, if you want to install the existing concealed hydraulic door closer with the positioning assembly 91 on the door panel, while the current concealed hydraulic door closer on the market is equipped with the positioning assembly 91, the door panel’s 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, in addition to the addition of an elongated slot 92 in the door panel, the brace 93 will inevitably be exposed to the door frame. In addition to destroying the original flat appearance, it is also because the upper end of the door panel is opened with a long strip. The slot 92 destroys the strength of the door panel and 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.

Because the current hidden hinges on the market also have the problem that they cannot be positioned, the wooden door panels, steel and aluminum door panels, etc., need to solve the positioning problem, so 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.

In the exposed hydraulic door closer with positioning assembly and the hidden hydraulic door closer with positioning assembly, because the exposed hydraulic door closer positioning assembly and the struts of the hidden hydraulic door closer will inevitably be exposed on the door panel and door frame , Destroy the flat appearance that was originally intended to be shaped, as shown in Figure 9 and Figure 10.

Please refer to Figure 11, 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.

In the following, in conjunction with the drawings and the preferred embodiments of this creation, the technical means adopted by this creation to achieve the predetermined creation purpose are further explained.

Please refer to Figure 1, Figure 3, and Figure 4, the hidden hinge with the opening angle of the temporary positioning function is used to be embedded in a door frame A1 and a door panel A2. The concealed hinge with the function of temporarily positioning the opening angle includes a first base 10, a second base 20, a pivot assembly 30, and a positioning assembly 40.

The first base 10 and the second base 20 are used to be buried in the door frame A1 and the door panel A2, respectively. Specifically, in this embodiment, the first base 10 is embedded in the door frame A1 and the second base 20 is embedded in the door panel A2, but in other embodiments, the first base 10 may be embedded in the door panel. A2 and the second base 20 is buried in the door frame A1.

Please further refer to FIGS. 2, 5, and 6, 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 connected by the pivot assembly 30 Relative pivoting. 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, the pivot assembly 30 further includes two tooth rods 32, two sliding blocks 33, and a pivot member 34. The pivot member 34 has two connecting portions 341, the aforementioned connecting block 31 is sandwiched between the two connecting portions 341, and the two connecting portions 341 extend into the second base 20 from the front 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 from the 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 the upper connecting portion 341, Finally, it is screwed down to the connecting block 31; and the lower tooth rod 32 first penetrates the lower sliding block 33 and then the lower connecting portion 341, and finally screwed up to the connecting block 31.

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 base 41 is fixed on the first base 10 or the second base 20 and is used to be buried in the corresponding door frame A1 or door panel A2. Specifically, in this embodiment, the base 41 is fixed to the second base 20, so the base 41 is also buried in the door panel A2; but in other embodiments, the base 41 may also be fixed to the first base. The base 10, and since the first base 10 is embedded in the door frame A1, the seat body 41 is embedded 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 continue to refer to FIGS. 2, 5, and 6, 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.

Please refer to Figures 2, 5, and 6, in this embodiment, a step surface 4111 is formed in the connecting channel 411, and the connecting rod 42 is screwed with a nut 51 on one end of the connecting rod 42 opposite to the screw thread connecting end 421. 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.

Please refer to Figures 3 and 5, when the door panel A2 is closed, that is, when the door panel A2 and the door frame A1 are relatively pivoted by 0 degrees, the connecting block 31 of the pivot assembly 30 has not yet pulled the connecting rod 42 toward the second base 20, and this The time positioning element 43 abuts against the annular wall surface of the connecting rod 42. 4 and 6, when the pivot angle θ of the door panel A2 relative to the door frame A1 is 90 degrees, that is, when the door panel A2 is opened 90 degrees relative to the door frame A1, the connecting block 31 of the pivotal assembly 30 faces the second The 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 422. As a result, the continuous movement of the connecting rod 42 can be temporarily stopped, so that the door panel A2 can be positioned at an opening 90 degree position relative to the door frame A1. Until the external force exerts a force greater than the elastic element 45 on the door panel A2 to lock the positioning element 43 in the positioning groove 422, the positioning element 43 can abut through the arc-shaped surface between the positioning groove 423 and the positioning element 43 and face the elastic 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, so that the door panel A2 can pivot relative to the door frame A1 again.

In addition, when the door panel A2 is opened to 90 degrees, the nut 51 abuts against the step surface 4111 via the washer 52, so the door panel A2 cannot be further opened to a greater pivot angle, but the nut 51 and the washer can be adjusted 52 on the connecting rod 42 to further adjust the maximum opening angle of the door panel A2; for example, in Fig. 6 rotating the nut 51 to move it to the right, the door panel A2 can be opened to greater than 90 degrees relative to the door frame A1, and vice versa If the nut 51 is rotated to move it to the left, the door panel A2 will be restricted by the nut 51 and the step surface 4111 before opening to 90 degrees and cannot continue to pivot and open relative to the door frame A1.

Please further refer to Figures 7 and 8, 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 to be aligned with the positioning channel 412 when the first base The relative pivot angle between the seat 10 and the second base 20; specifically, compared to the state in FIG. 6, the connecting rod 42 moves toward the second base 20, so that the positioning groove 422 also moves toward the second base 20 moves, so when the door frame A2 pivots to 75 degrees relative to the door panel A1, the positioning slot 422 is already facing the positioning channel 412 and is clamped by the positioning element 43, that is to say, the positioning angle is advanced to 75 degrees, and the positioning The angle can be determined by the facing position between the connecting block 31 and the connecting rod 42.

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 first base 10 or 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 10 When the two bases 20 are relatively pivoted by the pivoting assembly 30, the pivoting assembly 30 will drive the connecting rod 42 to move in the connecting passage 411 and selectively make the positioning groove 422 directly face the positioning passage 412.
