Description

Concealed hinge structure (1)

The present invention provides a hidden hinge structure, especially a hidden hinge structure that is not exposed, has a more beautiful overall structure, and can take into account the hinge support force, the balance of doors and windows, and the airtight and waterproof effect.

Press, hinge, usually installed on doors and windows, is a mechanical device used to connect the frame and the body of the door and window so that the two can be rotated. Common hinges are all one-stage rotations, and the user rotates them while pushing and pulling them. After rotating to a certain angle, the doors and windows are opened or closed.

One-stage rotary hinges can be divided into two types: "the center of rotation is outside the door and window" and "the center of rotation is inside the door and window": if the center of rotation is inside, the hinge will not be exposed outside the door and window during the movement of the door and window, driving the hinge The wheel body and track can also hide the upper and lower parts of the doors and windows, so it will not damage the appearance. At the same time, it can also reduce the load strength of the hinges and increase the service life to improve the look and feel. If the center of rotation is outside, the rotation action will not touch the frame, so There is no need to reserve a gap, and the airtight strip can also be pressurized and pressed to strengthen the airtight and waterproof effect.

However, when the above-mentioned one-stage rotary hinge is used, there are the following problems and deficiencies that need to be improved:

As shown in the first figure, if the center of rotation 91 is inside the door and window 9, no matter where the center of rotation 91 is located in the door or window 9, the radius of gyration 92 (the farthest distance from the center of rotation 91 to the outer edge of the door and window 9) will be too large. , So that when the doors and windows 9 are stuck on the frame 93 or the air-tight strip 94, it is usually solved by preserving the gap 95. However, the design of the gap 95 makes the aesthetic effect poor, and it is also not conducive to the air-tightness. The dense strip 94 performs pressurization and pressing action, or makes the air tightness and waterproof effect poor.

As shown in the second figure, if the center of rotation 91 is outside the door and window 9, the larger the volume of the door and window 9 is, the higher the load on the center of rotation 91 will be. In addition to the insufficient hinge support, the balance of the door and window 9 will be unbalanced. Good problem, and when the door and window 9 is opened or closed to 90 degrees, it will cause the hinge (position Same as the center of rotation 91) is exposed outside the doors and windows 9 and cannot achieve the aesthetic effect of hidden hinges. The door bodies and tracks that are exposed to drive the hinges to rotate will also be exposed above and below when the doors and windows 9 are closed, which seriously affects the appearance. The doors and windows 9 will be entirely outside the frame 93, so the doors and windows require a larger turning space.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the creators of the present invention and related manufacturers engaged in this industry urgently want to study and improve.

Therefore, in view of the above-mentioned deficiencies, the creator of the present invention collected relevant information, evaluated and considered multiple parties, and based on years of experience in this industry, through continuous trials and modifications, he designed this hinge structure without exposure, The overall appearance is more beautiful, and can take into account the hinge support force, the balance of doors and windows, and the airtight and waterproof structure of the invented hinge.

The main purpose of the present invention is to design a double turning center with one inside and one outside, and achieve the purpose of hiding the hinge, enhancing the overall look and feel, and having a wide range of applications with a two-stage turning motion, and has good airtightness, good waterproof performance and Advantages such as strong hinge support.

To achieve the above objective, the main structure of the present invention includes: at least one track carrier, a first sliding groove is formed on the track carrier, and a shaft member is provided on the track carrier, and a first turning interval is defined on the first sliding groove , And a second revolving section connected to the first revolving section, wherein the first revolving section is located on the side of the second revolving section away from the shaft member, and the curvature of the first revolving section is smaller than the curvature of the second revolving section, and is on the track The carrier is movably provided with a movable body that swings with the shaft member as the axis. A second sliding groove corresponding to the first sliding groove is formed on the movable body. A sliding member is movably arranged on the second sliding groove. A holding part movably arranged in the second sliding groove is formed, and a sliding part movably arranged in the first sliding groove and the second sliding groove is protruded from the sliding member, and the sliding part is additionally provided with a track carrier The connecting piece on the side away from the movable body.

When the user combines the present invention with doors and windows, the coupling piece is fixed to the door and window itself, so that the user can drive the coupling piece when pushing and pulling the door and window, and the movement of the coupling piece is directly linked to the sliding piece, so that it can be used as the door and window rotation axis. The sliding part moves along the first sliding groove. When the door and window are closed, the sliding part is located in the first turning interval and can move toward the second turning interval. At this time, the second sliding groove overlaps the first turning interval, so that the holding part and the sliding part are restricted to the movable body. The holding part controls the sliding and rotating actions of the sliding part, and at the same time avoids the rotation of the sliding part during the sliding process. Therefore, during the movement of the sliding part in the arc-shaped first rotation section, the center of rotation of the door and window is equivalent to In the first turning zone The center of the circle corresponding to the arc between the middle, and this center is located outside the door and window; when the door and window rotate to a certain angle, the sliding part is located at the junction of the first sliding interval and the second sliding interval, but for the second sliding groove The sliding part has moved to the end. At this time, when the doors and windows continue to rotate, the sliding part can only move along the second turning interval. During the movement of the sliding part in the arc-shaped second turning interval, the turning center of the door and window is equal At the center of the circle corresponding to the arc in the first revolving section, and this center is the axis member, and the axis member is located inside the door and window, so that the movable body, the second sliding groove, and the holding part are simultaneously based on the axis member swing.

It can be seen that when the sliding part slides in the first turning interval and the second sliding groove, the door and window rotate in the first stage, and the turning center is located outside the door and window, and when the sliding part enters the second turning interval from the end of the second sliding groove , The door and window are the second stage of rotation, and the center of rotation is located inside the door and window, so that it can simultaneously have the advantages of "the center of rotation is outside the door and window", the radius of rotation is short, no rotation gap is required, and the airtight and waterproof effect is good. The hinges where the center of rotation is inside the doors and windows are not exposed, the overall look and feel is good, the doors and windows are well balanced, and the hinges have strong support.

With the above technology, the problems of poor overall perception, poor airtightness, poor waterproof performance, and insufficient hinge support force of conventional one-stage hinges can be broken through, and the practical advancement of the above advantages can be achieved.

Based on the above description, the structure of this technology can be understood, and according to the corresponding cooperation of this structure, the hinge structure is not exposed, the overall appearance is more beautiful, and the hinge support force, the balance of doors and windows, and the airtight and waterproof effect can be taken into account. Advantages, and a detailed explanation will be explained below.

Please refer to Figures 3 to 9 at the same time, which are the three-dimensional perspective view to the action diagram (3) of the preferred embodiment of the present invention. When the above-mentioned components are assembled, it can be clearly seen from the figure that this In actual use, the invention cooperates with various opening and closing devices 7 such as folding doors, folding windows, flat sliding doors, or flat sliding windows, and the coupling member 5 is directly fixed on the opening and closing device 7, and the remaining components are arranged on 7 pairs of opening and closing devices The corresponding outer frame body 71 (as shown in the sixth figure), wherein the track carrier 1 is a rectangular sheet structure, and is arranged on the outer frame body 71 by means of adhesive bonding, and the first sliding groove 2 is opened in the track carrier 1 The upper two-section arc track, the first section is the first turning section 21 with a small curvature and a long length, which is set with the first turning center C1 outside the opening and closing device 7 as the center of the circle, and the second section is the curvature The larger and shorter second turning section 22 is set with the second turning center C2 inside the opening and closing device 7 as the center of the circle, and the second turning center C2 is defined on the shaft member 11, the shaft member 11 It is a columnar structure fixed on the track carrier 1. In addition, the movable body 3 is also a sheet structure, and the second sliding groove 31 is an arc-shaped track opened on the movable body 3, the length of which is greater than the first turning section 21, and the curvature is the same as that of the first turning section 21. As for the sliding member 4, it is a sheet-like structure with the smallest area, and is connected to the second sliding groove 31 through the holding portion 41, and the first sliding groove 2 and the second sliding groove 31 are simultaneously combined through the sliding portion 42, so the sliding portion 42 The length is greater than the length of the holding portion 41, and the sliding portion 42 serves as the rotation axis of the opening and closing device 7 and is the core structure of the overall operation. However, the shape and size of the above structure are only examples of preferred embodiments and are not limited.

In actual operation, as shown in Figures 7 and 8, when the opening and closing device 7 is in the closed state, the sliding portion 42 is located in the first end portion 211 of the first turning section 21, and the holding portion 41 is located in the second sliding groove 31 end, and can move together with the sliding portion 42 toward the junction 23 of the first turning section 21 and the second turning section 22. At this time, the second sliding groove 31 overlaps with the first turning section 21, so that the holding portion 41 and The sliding portion 42 is limited by the movable body 3, and the holding portion 41 is driven to control the sliding movement and rotation angle of the sliding portion 42. As for the sliding portion 42, the sliding movement of the sliding portion 42 is to make the opening and closing device 7 move away from the outside. The frame 71 moves in the direction to reserve a large gap for the second rotation. The rotation angle of the sliding part 42 is because the sliding part 42 and the holding part 41 are in the second sliding groove 31, so that the opening and closing device 7 only It can rotate in a small range while avoiding the rotation of the sliding member 4 during the sliding process, thereby stabilizing the overall operation process. Therefore, during the movement of the sliding part 42 in the first turning section 21, the opening and closing device 7 rotates and opens with the outer first turning center C1 as the center, so there is no need to reserve a gap to avoid the opening and closing device 7. Moreover, the air-tight strip can be tightly pressed to enhance the air-tight and waterproof effect.

As shown in the eighth and ninth figures, the opening and closing device 7 performs the second-stage rotation. Since the positional relationship between the first turning section 21 and the second turning section 22 is roughly V-shaped, the sliding portion 42 will stop at the junction 23 between the two during the movement. Specifically, the sliding portion 42 is in the first turning The moving direction in the section 21 is the first direction 212, and the sliding portion 42 is in the second turning area The moving direction in the space 22 is the second direction 222, and the angle θ between the first direction 212 and the second direction 222 is greater than 60 degrees and less than 120 degrees (this embodiment uses a V-shaped angle θ of about 100 degrees as an example ). When the user continues to push and pull the opening and closing device 7, because the sliding part 42 has been stopped at the end of the first turning section 21, it can only move toward the second end 221 of the second turning section 22, and the sliding section 42 is at During the movement in the second turning section 22, the opening and closing device 7 rotates and opens with the inner second turning center C2 as the center of the circle. In addition, because the second center of rotation C2 is where the axis member 11 is located, the movable body 3 can swing with the axis member 11 as the axis at the same time, so that the holding portion 41 can swing greatly along with the movable body 3 to keep the The portion 41 and the sliding portion 42 have to rotate at a large angle at the same time. Since the opening and closing device 7 has created a sufficient swing gap during the first stage of rotation, it can easily flash past the outer frame 71 even if the radius of rotation is large. C2 is the axis to rotate, so that the opening and closing device 7 requires a smaller rotation space, the volume protruding from the outer frame 71 after fully opened is less, and the weight of the opening and closing device 7 is also lighter on the hinge. The balance during opening and closing is improved, and the hinge can be completely hidden above the opening and closing device 7 (it may be hidden below depending on the installation position), so as to avoid damage to the appearance.

Please also refer to the tenth and eleventh figures, which are combined schematic diagrams and exploded views of another preferred embodiment of the present invention. It can be clearly seen from the figures that this embodiment is similar to the above-mentioned embodiment. , Only the rail carrier 1a has a plurality of joints 12a, the joints 12a are screw holes, so it can be used with screws and other locking elements 121a to fix the rail carrier 1a on the outer frame 71a to increase the overall joint strength . In addition, in this embodiment, the number of track carriers 1a is increased to two, so that the movable body 3a and the sliding member 4a are located between the track carriers 1a, and there is an outer frame buffer 13a between the track carriers 1a and a plurality of positions corresponding to each The coupling portion 12a is coupled with the buffer 14a. Among them, the outer frame buffer 13a and the combined buffer 14a can leave enough space between the two rail carriers 1a, so that the movable body 3a and the sliding member 4a will not be too large due to the clamping force of the two rail carriers 1a. It is difficult to move, and because the track carrier 1a is fixed by the joint 12a, even if the internal structure of the movable body 3a and the sliding member 4a are damaged, they can be easily removed and replaced.

Furthermore, in this embodiment, an auxiliary piece 43a is sleeved on the holding portion 41a and the sliding portion 42a. The auxiliary piece 43a is a hollow cylinder made of smooth material as an example to increase the movement of the holding portion 41a and the sliding portion 42a. Smoothness. There is a protective member 6a between the coupling member 5a and the sliding member 4a, and a protective wing 61a for shielding the first sliding groove 2a and the second sliding groove 31a is formed on the protective member 6a. The protective part 6a is made of waterproof and airtight material, It is mainly used to prevent the sliding part 42a, which is the axis of rotation of the opening and closing device 7a, from being unsatisfactory due to water seepage or dust accumulation. The protective wings 61a are used to shield the first sliding groove 2a and the second sliding groove 31a. The wing 61a has a special shape, so that the opening and closing device 7a can completely shield the first sliding groove 2a and the second sliding groove 31a regardless of the rotation angle, so as to achieve the purpose of waterproof and dustproof.

Please also refer to Figure 12, which is a three-dimensional perspective view of another preferred embodiment of the present invention. It can be clearly seen from the figure that this embodiment is similar to the above-mentioned embodiment, except for the track carrier 1b. There is a sliding device 8b on the away coupling member 5b, which is movable on the outer frame 71b. The sliding device 8b of this embodiment uses a pulley as an example, and is coupled to the guide groove 711b of the outer frame 71b. The opening and closing device 7b of this embodiment is implemented as a folding window or a folding door. As long as the rail carrier 1b is combined with the sliding device 8b, and the sliding device 8b is moved along the outer frame 71b, the present invention The opening and closing device 7b is suitable for folding windows or doors. In addition, if the sliding device 8b is not used, a simple cylindrical structure 81b can still be inserted into the guide groove 711b to allow the opening and closing device 7b to slide, so as to achieve the purpose of folding windows or doors.

However, the above descriptions are only preferred embodiments of the present invention, and are not limited to the scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the description and drawings of the present invention should be the same.
