Description

Technical Field

[0001] This invention relates to the field of home furnishing products, and more specifically to a connecting device, a door structure, and a sliding door structure. Background Technology

[0002] In existing technology, diamond-shaped shower enclosures are suitable for families with small bathrooms. Their advantage lies in high space utilization; by using three panes of glass arranged at obtuse angles in pairs around a corner of the bathroom, a separate wet and dry shower area can be created. Diamond-shaped shower enclosures are further divided into hinged door diamond-shaped shower enclosures and inward-opening door diamond-shaped shower enclosures. Compared to hinged door diamond-shaped shower enclosures, inward-opening door diamond-shaped shower enclosures eliminate the need for clearance when opening and closing the door, further improving space utilization. However, due to the limited space and the inward-opening door structure, their disadvantages are also obvious: the door opening width is smaller, which is extremely unfriendly to larger users. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned defects or problems in the prior art and to provide a connecting device, a door structure, and a sliding door structure.

[0004] To achieve the above objectives, the present invention and its preferred embodiments employ the following technical solutions, but the embodiments are not limited to the following solutions:

[0005] Option 1, a connecting device for connecting an inner flying door to a sliding rail, comprising:

[0006] The first slider slides along the slide rail;

[0007] A rotating component, rotatably connected to the first sliding component about a first axis perpendicular to the extension direction of the slide rail; and

[0008] A first connecting member is installed on the inner flying door and rotatably connected to the rotating member about a second axis parallel to the first axis. When the first sliding member slides to the end of the slide rail, the rotating member is adapted to rotate relative to the first sliding member about the first axis in a first circumferential direction, and at the same time, the first connecting member rotates relative to the rotating member about the second axis in the opposite direction of the first circumferential direction.

[0009] Option 2, based on Option 1, involves the rotating member being configured such that when the first sliding member slides to the end of the slide rail, the rotating member is subjected to a rotational torque generated by the thrust of the inner flying door, causing the first connecting member to rotate relative to the rotating member about the second axis in the opposite direction of the first circumferential direction.

[0010] Option 3, based on Option 1, the rotating component includes a first rotating part and a second rotating part. The second rotating part is rotatably connected to the first connecting member about a second axis, and the first rotating part is rotatably connected to the first sliding member about a first axis. The extension direction of the first rotating part intersects the extension direction of the second rotating part, and the extension direction of the first rotating part is adapted to be parallel to the extension direction of the slide rail.

[0011] Option 4, based on Options 1 to 3, involves the first connecting member and the rotating member rotating relative to the first sliding member around a first axis during the sliding process of the first sliding member relative to the slide rail.

[0012] Option 5, based on Option 4, further includes an elastic element, one end of which is connected to the first connecting member, and the other end of which is connected to the rotating member, and applies a damping force to the first connecting member to prevent the first connecting member from easily rotating relative to the rotating member.

[0013] Option 6, based on Option 5, the first connector is provided with a mounting post, the mounting post is provided with a mounting hole that penetrates the first connector in a direction perpendicular to the second axis, and the two ends of the elastic member are respectively provided with a first hook part and a second hook part. The first hook part penetrates the mounting hole and hooks onto the mounting post, and the second hook part hooks onto the rotating member.

[0014] Option 7, based on Option 1, the first connecting member is provided with a first limiting part and a second limiting part that both extend along the direction of the first axis. The rotating member is adapted to abut against the first limiting part and the second limiting part to limit the rotation range of the first connecting member relative to the rotating member.

[0015] Option 8, based on Option 7, is that the rotating member is adapted to have flexibility in the portion that abuts against the first limiting portion and the second limiting portion.

[0016] Option 9, a door structure, includes a connecting device and an inner flying door as described in any one of Options 1 to 8, wherein there are two connecting devices, which are respectively disposed at both ends of the inner flying door along the direction of the first axis, and the two ends of the inner flying door along the direction of the first axis are respectively fixedly connected to the two first connecting members.

[0017] Option 10, based on Option 9, further includes two sliding components. The two sliding components are respectively disposed at both ends of the inner air door along the direction of the first axis. Each sliding component includes a second connector and a second sliding member. The second connector is fixedly connected to the inner air door, and the second sliding member and the second connector are rotatably connected about a third axis parallel to the first axis.

[0018] Option 11, a sliding door structure, includes a door structure as described in Option 10, and a first track and a second track arranged opposite to each other. The first track includes a first slide rail and a second slide rail that intersect each other. The second track is provided with a third slide rail and a fourth slide rail that correspond to the first slide rail and the second slide rail respectively. Two first sliding members are respectively adapted to slide with the first slide rail and the third slide rail, and two second sliding members are respectively adapted to slide with the second slide rail and the fourth slide rail.

[0019] Option 12, based on Option 11, further includes a first fixed door, with both ends of the first fixed door fixed to the first track and the second track respectively along the direction of the first axis, and the inner flying door is adapted to move to the rear side of the first fixed door.

[0020] Option thirteen, based on option eleven, further includes a friction pad, which is installed on the first track and the second track. When the two first sliding members slide to the ends of the first and third slide rails, the two first sliding members abut against the friction pads on the first track and the second track, respectively.

[0021] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0022] 1. In Scheme 1 and its preferred embodiments, a connecting device is used to connect an inner flying door to a slide rail. The connecting device includes a first sliding member, a rotating member, and a first connecting member.

[0023] The first sliding member slides along the slide rail to guide the movement of the inner flying door. The rotating member is used to transmit the force of the first connecting member to the first sliding member. The rotating member is rotatably connected to the first sliding member about a first axis perpendicular to the extension direction of the slide rail. The first connecting member is installed on the inner flying door and rotatably connected to the rotating member about a second axis parallel to the first axis. When the first sliding member slides to the end of the slide rail, the rotating member is adapted to rotate relative to the first sliding member about the first axis in a first circumferential direction. At the same time, the first connecting member rotates relative to the rotating member about the second axis in the opposite direction of the first circumferential direction, thereby allowing the inner flying door to fold further, so that the entrance and exit width generated by the opening of the inner flying door is larger, making it more convenient for users to enter and exit.

[0024] 2. In Scheme 2 and its preferred embodiment, when the first sliding member slides to the end of the slide rail, the rotating member is configured to generate a rotational torque due to the thrust of the inner door, causing the first connecting member to rotate relative to the rotating member in the opposite direction of the first circumferential direction around the second axis. The user can further fold the inner door without changing the direction of the applied force, making the operation simple.

[0025] 3. In Scheme 3 and its preferred embodiments, the rotating component includes a first rotating part and a second rotating part. The second rotating part is rotatably connected to the first connecting member about a second axis, and the first rotating part is rotatably connected to the first sliding member about a first axis. The extension direction of the first rotating part intersects the extension direction of the second rotating part. Since the extension direction of the first rotating part is adapted to be parallel to the extension direction of the slide rail, in some cases, such as when initially opening the door, the force applied by the user to the inward door can form a larger component of force acting on the first sliding member, making the first sliding member easier to slide.

[0026] 4. In Scheme 4 and its preferred embodiments, if the first connecting member and the rotating member rotate relative to each other during the sliding process of the first sliding member relative to the slide rail, it may lead to the formation of a dead point (such as the direction of the applied force pointing towards the first axis). When the first sliding member slides to the end of the slide rail, it will be difficult for the user to apply force to make the inward door fold further, resulting in inconvenience in use. Therefore, in this scheme, the first connecting member and the rotating member rotate relative to the first sliding member around the first axis during the sliding process of the first sliding member relative to the slide rail, which can reduce the possibility of the above phenomenon occurring.

[0027] 5. In Scheme 5 and its preferred embodiments, one end of the elastic member is connected to the first connecting member, and the other end of the elastic member is connected to the rotating member. A damping force is applied to the first connecting member to prevent the first connecting member from easily rotating relative to the rotating member, thereby preventing the first sliding member from forming a dead point by relative rotation between the first connecting member and the rotating member during the sliding process relative to the slide rail.

[0028] 6. In Scheme 6 and its preferred embodiments, the first connecting member is provided with a mounting post, and the mounting post is provided with a mounting hole that penetrates the first connecting member in a direction perpendicular to the first axis. The two ends of the elastic member are respectively provided with a first hook part and a second hook part. The first hook part is hooked to the mounting post after penetrating the mounting hole, and the second hook part is hooked to the rotating member, thereby realizing the installation of the elastic member and preventing the first connecting member and the rotating member from rotating relative to each other during the sliding of the first sliding member relative to the slide rail.

[0029] 7. In Scheme 7 and its preferred implementation, the first connecting member is provided with a first limiting part and a second limiting part, both extending along the direction of the first axis. The rotating member is adapted to abut against the first limiting part and the second limiting part to limit the rotation range of the first connecting member relative to the rotating member. When the rotating member and the first connecting member are in the closed position, the rotating member abuts against the first limiting part. When the inner door is further folded, the rotating member abuts against the second limiting part. This prevents over-rotation from causing the inner door to collide with the fixed door or wall, resulting in product damage, or from friction with the fixed door, causing the first sliding member to be difficult to slide.

[0030] 8. In Scheme 8 and its preferred implementation, the part of the rotating component that abuts against the first limiting part and the second limiting part is flexible, thereby preventing damage and abnormal noise caused by hard collision.

[0031] 9. In Scheme 9 and its preferred implementation, a door structure includes the aforementioned connecting device and an inner flying door. The number of connecting devices is two, and they are respectively disposed at both ends of the inner flying door along the direction of the first axis. The two ends of the inner flying door along the direction of the first axis are respectively fixedly connected to two first connecting members, which has the beneficial effects brought about by the aforementioned connecting device.

[0032] 10. In Scheme 10 and its preferred implementation, the two sliding components are respectively set at both ends of the inner air door along the direction of the first axis. Each sliding component includes a second connecting member and a second sliding member. The second connecting member is fixedly connected to the inner air door, and the second sliding member and the second connecting member are rotatably connected around a third axis parallel to the first axis. The two sliding components and the two connecting devices are installed together on the inner air door, thereby increasing the stability of the inner air door movement.

[0033] 11. In Scheme Eleven and its preferred embodiments, a sliding door structure includes the door structure described above, and a first track and a second track arranged opposite to each other. The first track includes a first slide rail and a second slide rail that intersect each other. The second track has a third slide rail and a fourth slide rail that correspond to the first slide rail and the second slide rail, respectively. Two first sliding members are adapted to slide with the first slide rail and the third slide rail, respectively, and two second sliding members are adapted to slide with the second slide rail and the fourth slide rail, respectively. The first track and the second track are used to guide the movement of the sliding door. This scheme has the beneficial effects brought by the above-described door structure.

[0034] 12. In Scheme Twelve and its preferred implementation, a first fixed door is also included. The two ends of the first fixed door along the direction of the first axis are fixed to the first track and the second track respectively. The inner flying door is adapted to move to the rear side of the first fixed door, thereby realizing the opening of the entrance and exit.

[0035] 13. In Scheme Thirteen and its preferred implementation, friction pads are installed on the first and second tracks. When the two first sliding members slide to the ends of the first and third tracks, the two first sliding members abut against the friction pads on the first and second tracks respectively, thereby preventing the inward flying door from moving easily and ensuring the opening of the entrance and exit.

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are preferred embodiments of the present invention and should not be considered as excluding other embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0056] Unless otherwise expressly defined, in the claims, description, and accompanying drawings of this invention, the use of directional terms such as "center," "lateral," "longitudinal," "horizontal," "vertical," "top," "bottom," "inner," "outer," "upper," "lower," "front," "rear," "left," "right," "clockwise," and "counterclockwise" to indicate orientation or positional relationships is based on the orientation and positional relationships shown in the accompanying drawings and is only for the convenience of describing the invention and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the specific scope of protection of this invention.

[0057] Unless otherwise expressly defined, the terms "fixed connection" or "fixed connection" used in the claims, description and drawings of this invention should be interpreted broadly to refer to any connection in which there is no displacement or relative rotation relationship between the two parties, including non-removable fixed connection, detachable fixed connection, integral connection and fixed connection by other means or components.

[0058] In the claims, description and accompanying drawings of this invention, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0059] refer to Figures 1-12A sliding door structure includes a door structure, a first track 4, a second track 5, a first fixed door 6, a second fixed door 7, and a friction pad 10. The door structure includes an inner flying door 2, two connecting devices 1, and two sliding components 3.

[0060] refer to Figure 1 The first track 4 and the second track 5 are used to guide the movement of the inner flying door 2 and to secure the first fixed door 6 and the second fixed door 7. The first track 4 and the second track 5 are arranged opposite to each other, with the first track 4 located below the second track 5. (Reference) Figure 2 The first track 4 is provided with a first slide rail 41, a second slide rail 42 and a first fixing groove 43 that intersect each other, with the first slide rail 41 and the first fixing groove 43 respectively located on the left and right sides of the second slide rail 42. The second track 5 is provided with a third slide rail, a fourth slide rail and a second fixing groove respectively corresponding to the first slide rail 41, the second slide rail 42 and the first fixing groove 43.

[0061] refer to Figure 1 The first fixed door 6 is fixed at both ends of the first track 4 and the second track 5 along the vertical direction. The vertical direction is the height direction of the inner flying door 2. The second fixed door 7 is fixed at both ends of the first fixed groove 43 and the second fixed groove along the vertical direction. When the inner flying door 2 is closed, the inner flying door 2 is located between the first fixed door 6 and the second fixed door 7.

[0062] refer to Figure 13 , Figure 15 The friction pad 10 is used to provide friction to prevent the inner flying door 2 from sliding easily. The friction pad 10 is installed on the first track 4 and the second track 5. In this embodiment, the ends of the first slide rail 41, the second slide rail 42, the third slide rail and the fourth slide rail are all equipped with friction pads 10. The friction pad 10 is generally set at the bottom of the slide rail.

[0063] refer to Figure 1 The connecting device 1 is used to connect the inner flying door 2 to the first slide rail 41 and the third slide rail. The two connecting devices 1 are respectively set at both ends of the inner flying door 2 in the vertical direction, and both connecting devices 1 are located on the left side of the inner flying door 2, which is the side close to the first fixed door 6.

[0064] refer to Figure 4 The connecting device 1 includes a first sliding member 11, a rotating member 12, a first connecting member 13, and an elastic member 14.

[0065] refer to Figure 4 The two first sliding members 11 are respectively adapted to slide and cooperate with the first slide rail 41 and the third slide rail to guide the movement of the inner flying door 2. The first sliding member 11 is also provided with a roller to reduce the friction during sliding.

[0066] refer to Figure 8The rotating member 12 includes a first rotating part 121 and a second rotating part 122, such as Figure 3 As shown, the extension direction of the first rotating part 121 intersects the extension direction of the second rotating part 122, and the extension direction of the first rotating part 121 is adapted to be parallel to the extension directions of the first slide rail 41 and the third slide rail.

[0067] refer to Figure 12 The first rotating part 121 is rotatably connected to the first sliding member 11 about a first axis 8 perpendicular to the extending direction of the first slide rail 41 and the third slide rail, wherein the direction of the first axis 8 is vertical. (Reference) Figure 11 The second rotating part 122 is rotatably connected to the first connecting member 13 about a second axis 9 parallel to the first axis 8.

[0068] refer to Figure 3 The first connecting member 13 is used to install on the inner flying door 2, and the two ends of the inner flying door 2 in the vertical direction are respectively fixedly connected to the two first connecting members 13. The first connecting member 13 is rotatably connected to the rotating member 12 around the second axis 9.

[0069] refer to Figure 9 The first connector 13 is provided with a mounting post 134, and the mounting post 134 has a mounting hole 133 that penetrates the first connector 13 in a direction perpendicular to the second axis 9 (i.e., perpendicular to the vertical direction). The first connector 13 is provided with a first limiting part 131 and a second limiting part 132 that both extend in the vertical direction. (Refer to...) Figure 3 , Figure 5 The rotating member 12 is adapted to abut against the first limiting portion 131 and the second limiting portion 132 to limit the rotation range of the first connecting member 13 relative to the rotating member 12, thereby preventing over-rotation that could cause the inner flying door 2 to collide with the first fixed door 6 or the wall, resulting in product damage. The portion of the rotating member 12 that abuts against the first limiting portion 131 and the second limiting portion 132 is flexible, such as being made of soft rubber, to prevent damage and abnormal noise caused by hard impacts. Other parts of the rotating member 12 can be made of hard metal or plastic to ensure strength.

[0070] refer to Figure 3 One end of the elastic element 14 is connected to the first connecting element 13, and the other end of the elastic element 14 is connected to the rotating element 12, applying a damping force to the first connecting element 13 to prevent the first connecting element 13 from easily rotating relative to the rotating element 12. Specifically, the two ends of the elastic element 14 are respectively provided with a first hook portion 141 and a second hook portion 142. The first hook portion passes through the mounting hole 133 and hooks onto the mounting post 134, while the second hook portion 142 hooks onto the rotating element 12.

[0071] During the sliding of the first sliding member 11 relative to the slide rail, if the first connecting member 13 and the rotating member 12 rotate relative to each other, it may cause a dead point to be formed (such as the direction of the applied force pointing towards the first axis 8). When the first sliding member 11 slides to the end of the slide rail, it will be difficult for the user to apply force to make the inner flying door 2 fold further, resulting in inconvenience in use. With the setting of the elastic member 14, the elastic member 14 can apply damping force to the first connecting member 13 to prevent the first connecting member 13 from easily rotating relative to the rotating member 12, which can reduce the occurrence of the above problems.

[0072] refer to Figure 1 The sliding assembly 3 is used to connect the inner door 2 to the second slide rail 42 and the fourth slide rail. The two sliding assemblies 3 are respectively disposed at both ends of the inner door 2 in the vertical direction, and both sliding assemblies 3 are located on the right side of the inner door 2. (Refer to...) Figure 14 The sliding assembly 3 includes a second connecting member 31 and a second sliding member 32. The second connecting member 31 is fixedly connected to the inner door 2, and the second sliding member 32 is rotatably connected to the second connecting member 31 about a third axis parallel to the first axis 8. The two second sliding members 32 are respectively slidably engaged with the second slide rail 42 and the fourth slide rail. The two sliding assemblies 3 and the two connecting devices 1 are installed together on the inner door 2, thereby increasing the stability of the movement of the inner door 2.

[0073] In use, the connecting device 1 and the sliding assembly 3 are installed on the inner door 2, and then together on the first track 4 and the second track 5. When the inner door 2 is closed, it is parallel to the left and right directions, and the rotating part 12 abuts against the first limiting part 131. When the user wants to open the inner door 2, the user applies force to the right end of the inner door 2 to the left. Since the extension direction of the first rotating part 121 is adapted to be parallel to the extension direction of the first slide rail 41 and the third slide rail, the force applied by the user to the inner door can form a larger component force acting on the first sliding part 11, making the first sliding part 11 easier to slide.

[0074] During the sliding process, the two second sliding members 32 will slide relative to the second slide rail 42 and the fourth slide rail respectively, as follows: Figure 6 As shown, due to the action of the elastic element 14, the first connecting element 13 and the rotating element 12 will not rotate relative to each other temporarily. The first connecting element 13 and the rotating element 12 rotate relative to the first sliding element 11 around the first axis 8. At the same time, the second connecting element 31 and the second sliding element 32 rotate around the third axis, thereby changing the posture of the inner flying door 2. During the sliding process, the inner flying door 2 gradually moves to the rear side of the first fixed door 6. When the two first sliding elements 11 slide to the ends of the first slide rail 41 and the third slide rail respectively, the two first sliding elements 11 abut against the friction pads 10 on the first slide rail 41 and the third slide rail respectively (if the first sliding element 11 is equipped with a pulley, the pulley abuts against the friction pad 10), thereby preventing the inner flying door 2 from moving easily and ensuring that the entrance and exit are open.

[0075] refer to Figure 5 , Figure 7 When the user applies further force to the inner door 2, the rotating member 12 is configured to generate a rotational torque due to the thrust of the inner door 2, causing the first connecting member 13 to rotate relative to the rotating member 12 around the second axis 9 in the opposite direction of the first circumferential direction. This allows the user to further fold the inner door 2 without changing the direction of the applied force, simplifying the operation. After operation, the rotating member 12 is adapted to rotate relative to the first sliding member 11 around the first axis 8 in the first circumferential direction (…). Figure 7 The first connecting member 13 rotates counterclockwise relative to the rotating member 12 in the opposite direction of the first circumferential direction around the second axis 9. Figure 7 The upper part rotates clockwise (away from the first slide rail 41), while the second connecting member 31 rotates relative to the second sliding member 32 around the third axis. As the two second sliding members 32 continue to slide along the second and fourth slide rails to their ends, they abut against the friction pads 10 on the second and fourth slide rails respectively, causing the inner door 2 to fold further and the entrance / exit to open further, thus increasing the width of the entrance / exit and making it easier for users to enter and exit. At this time, the rotating member 12 abuts against the second limiting part 132. Although the elastic member 14 stores energy when the first connecting member 13 rotates relative to the rotating member 12, its restoring force is small and insufficient to reset the first connecting member 13 and the rotating member 12. Therefore, the inner door 2 remains in a further folded state. The action is reversed when closing the door.

[0076] The second fixed door 7 can make the shower space larger. In other embodiments, the sliding door structure can also be a non-diamond-shaped door. For example, in this embodiment, the sliding door structure may not have the second fixed door 7. The sliding door structure is roughly rectangular after being combined with the wall. The first fixed door 6 and the inner flying door 2 are respectively abutted against the walls that are perpendicular to each other.

[0077] In addition to being used on the inner door 2, the connecting device 1 can also be used on windows or other parts that require further folding.

[0078] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this invention, but does not constitute a limitation on the scope of protection of this invention. Modifications, equivalent substitutions, or other improvements to the embodiments of this invention or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
