Description

Technical Field

[0001] The invention relates to the field of furniture, and in particular to a limiting mechanism for a coplanar door track-changing sliding mechanism. Background Art

[0002] Due to the limitation of space utilization, furniture with sliding doors, such as wardrobes or room doors, is increasingly widely used. To open one of the door leaves of a coplanar door, it is necessary to disengage the door leaf from the adjacent door leaf. When closing the door leaf, it is necessary to use an arc-shaped curved track to change the running track of the door leaf so that the closed door leaves can be coplanar. However, the setting of the arc-shaped curved track means that the coplanar door cannot be cut according to the size of the furniture during installation and use. The application is inflexible, the stocking is inconvenient, the production is difficult, and the application cost is too high. Summary of the invention

[0003] In view of the defects of the prior art, the present invention provides a limiting mechanism for a coplanar door track-changing sliding mechanism to solve the problem that the coplanar door track-changing sliding mechanism itself can achieve track change.

[0004] The technical solution adopted by the present invention to solve the problem is:

[0005] A limiting mechanism for a coplanar door track-changing sliding mechanism comprises a limiting base, a movable limiting member movably connected to the limiting base, a fixing member rotatably connected to the movable limiting member, and a limiting toggle member for triggering the movable limiting member to generate displacement;

[0006] The limiting base is arranged between the movable limiting member and the fixed member. When the movable limiting member contacts the limiting toggle member, the movable limiting member rotates relative to the fixed member, so that the movable limiting member is displaced relative to the limiting base.

[0007] The limiting mechanism for the coplanar door track-changing sliding mechanism provided by the present invention changes the state of the movable limiting member by contacting the limiting toggle member with the movable limiting member, and the movable limiting member rotates relative to the fixed member, so that the movable limiting member is displaced relative to the limiting base, thereby realizing that the coplanar door track-changing sliding mechanism can complete track change on a straight track through the mechanism.

[0008] Furthermore, the movable limiting member is provided with a locking member for clamping the movable limiting member; the fixing member is provided with a connecting column; the connecting column is rotatably connected to the movable limiting member, and the connecting column is rotatably connected to the elastic member; the elastic member is elastically connected to the locking member.

[0009] Furthermore, the limiting base is provided with a limiting hole for guiding the displacement of the movable limiting member, and the limiting hole is provided with a clamping groove for clamping the movable limiting member; the connecting column and the clamping member are respectively slidably connected to the limiting hole.

[0010] Furthermore, the position-limiting toggle member includes a base and a toggle member disposed on the base.

[0011] Furthermore, the shifting member is a rotating wheel.

[0012] Furthermore, the movable limiting member is provided with a first arc-shaped groove, and a groove surface of the first arc-shaped groove is tangent to a wheel surface of the toggle member.

[0013] Furthermore, the limiting mechanism also includes a fixed limiting member fixed relative to the fixing member and a guide hole provided on the limiting base for guiding the displacement of the fixed limiting member.

[0014] Furthermore, the fixed limiting member is provided with a straight groove and a second arc groove connected to the straight groove, and when the toggle member contacts the movable limiting member, the movable limiting member is driven to rotate so that the groove surface of the first arc groove is correspondingly connected with the groove surface of the second arc groove.

[0015] Furthermore, an isolating member is provided between the fixing member and the movable limiting member, and the isolating member and the movable limiting member are relatively fixed.

[0016] Therefore, when the toggle member contacts the movable limit member, the movable limit member is driven to rotate, causing the locking member on the movable limit member to overcome the elasticity of the elastic member and slide out of the locking groove, so that the movable limit member slides and displaces relative to the limit base along the groove surface after the first arc groove and the second arc groove are connected.

[0017] Therefore, the movable limiting member will be in active contact with the toggle member and the fixed limiting member during use, and the movable limiting member made of plastic material can reduce the impact force of the collision during contact and reduce the noise.

[0018] Furthermore, it also includes an elastic reset member for resetting the displacement of the movable limiting member.

[0019] Furthermore, the elastic return member is a spring.

[0020] Furthermore, it also includes a roller, which is in sliding contact with the spring so that the spring forms an "L"-shaped structure.

[0021] Furthermore, the elastic reset member is a reset spring sheet, so that the movable limiting member has an elastic pulling force when it is displaced relative to the limiting base.

[0022] Therefore, under the action of the elastic reset member, the movable limiting member is facilitated to be smoothly displaced and reset on the limiting base.

[0023] In summary, the limiting mechanism for the coplanar door track-changing sliding mechanism provided by the present invention has the following beneficial effects:

[0024] (1) The limit toggle member contacts the movable limit member, changes the state of the movable limit member, and causes the movable limit member to rotate relative to the fixed member, so that the movable limit member is displaced relative to the limit base, thereby realizing the coplanar door track change sliding mechanism, through which the track change can be completed on the straight track.

[0025] (2) When the toggle member contacts the movable limiting member, the movable limiting member is driven to rotate, so that the locking member on the movable limiting member overcomes the elasticity of the elastic member and slides out of the locking groove, so that the movable limiting member slides relative to the limiting base along the groove surface after the first arc groove and the second arc groove are connected and generates displacement.

[0026] (3) The movable limiter will come into contact with the toggle member and the fixed limiter during use. The movable limiter made of plastic reduces the impact force of the collision during contact and reduces noise.

[0027] (4) Under the action of the elastic reset member, the movable limit member is facilitated to be smoothly displaced and reset on the limit base. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0038] like Figure 1-3 As shown, the limiting mechanism for the coplanar door track-changing sliding mechanism provided by the present invention, the limiting mechanism 3 includes a limiting base 33, a movable limiting member 31 movably connected to the limiting base 33, and a fixing member 34; the limiting base 33 is arranged between the movable limiting member 31 and the fixing member 34, and the movable limiting member 31 is rotatably connected to the fixing member 34, when the movable limiting member 31 contacts the limiting toggle member 5, the movable limiting member 31 rotates relative to the fixing member 34, so that the movable limiting member 31 is displaced relative to the limiting base 33. The limiting toggle member 5 includes a base 51 and a toggle member 52 arranged on the base 51. The toggle member 52 is a rotating wheel. The movable stopper 31 is provided with a clamping piece 36 for clamping the movable stopper 31; the fixing piece 34 is provided with a connecting column 35; the connecting column 35 is rotatably connected to the movable stopper 31, and the connecting column 35 is rotatably connected to the elastic piece 37; the elastic piece 37 is elastically connected to the clamping piece 36. The limit base 33 is provided with a limit hole 331 for guiding the displacement of the movable stopper 31, and the limit hole 331 is provided with a clamping groove 3311 for clamping the movable stopper 31; the connecting column 35 and the clamping piece 36 are slidably connected to the limit hole 331 respectively. The movable stopper 31 is provided with a first arc groove 311, and the groove surface of the first arc groove 311 is tangent to the wheel surface of the toggle member 52.

[0039] When the coplanar door is opened, the elastic member 37 clamps the locking member 36 in the slot 3311; when the coplanar door is closed, the toggle member 52 is connected to the movable limiting member 31, and the locking member 36 overcomes the elastic force of the elastic member 37 and slides out of the slot 3311, so that the limiting mechanism 3 drives the door panel fixing seat 2 to move along the groove surface of the first arc groove 311 and generate displacement relative to the sliding mechanism 1 to achieve the coplanar closing of the coplanar door.

[0040] In this embodiment, the limiting mechanism 3 further includes a fixed limiting member 32 fixed relative to the fixing member 34 and a guide hole 332 provided on the limiting base 33 for guiding the displacement of the fixed limiting member 32. The fixed limiting member 32 is provided with a straight groove 321 and a second arc groove 322 connected with the straight groove 321. When the toggle member 52 contacts the movable limiting member 31, it drives the movable limiting member 31 to rotate, so that the groove surface of the first arc groove 311 is correspondingly connected with the groove surface of the second arc groove 322. The movable limiting member 31 is provided with a sharp corner, and the sharp corner moves in the second arc groove 322 during the rotation of the movable limiting member 31, and will not collide with the fixed limiting member 32. When the locking member 36 contacts the hole wall of the limiting hole 331, the movable limiting member 31 stops rotating. At this time, the groove surface of the first arc groove 311 and the groove surface of the second arc groove 322 are correspondingly connected, so that the first arc groove 311 and the second arc groove 322 are connected to form a complete arc groove passing through the toggle member 52. An isolation member 38 is provided between the fixing member 34 and the movable limiting member 31 to prevent the elastic member 37 from being stuck in the limiting hole 331. The isolation member 38 is relatively fixed to the movable limiting member 31.

[0041] The movable stopper 31 will be in active contact with the toggle member 52 and the fixed stopper 32 during use. The movable stopper 31 made of plastic can reduce the impact force of the collision during contact and reduce noise.

[0042] Thus, the toggle member 52 contacts the movable limit member 31, prompting the locking member 36 on the movable limit member 31 to overcome the elasticity of the elastic member 37 and slide out of the locking groove 3311. At this time, the movable limit member 31 slides relative to the limit base 33, so that the limit mechanism 3 drives the door panel fixing seat 2 to move along the groove surface of the first arc groove 311, and produces displacement relative to the sliding mechanism 3, so as to realize the coplanar closure of the coplanar doors.

[0043] like Figure 5As shown, the limit mechanism 3 further includes an elastic reset member 39, which is connected between the sliding mechanism 1 and the door panel fixing seat 2. The elastic reset member 39 is a spring. The door panel fixing seat 2 is provided with a roller 23, and the roller 23 is in sliding contact with the spring so that the spring forms an "L"-shaped structure. In another case, the elastic reset member 39 is a reset spring so that the movable limit member 31 has an elastic pulling force when it is displaced relative to the limit base 33.

[0044] Therefore, under the action of the elastic reset member 39, the limiting mechanism 3 is conducive to driving the door panel fixing seat 2 to change track smoothly.

[0045] Figure 4 The structure shown is a schematic diagram of the above-mentioned limiting mechanism applied to the coplanar door track changing sliding mechanism, which includes a door panel fixing seat 2, a sliding mechanism 1 for realizing the displacement of the door panel fixing seat 2, a limiting mechanism 3 for realizing the track changing of the door panel fixing seat 2, and a limiting toggle member 5 for triggering the displacement of the limiting mechanism 3; the limiting mechanism 3 is connected between the sliding mechanism 1 and the door panel fixing seat 2; the limiting toggle member 5 is arranged at the terminal of the moving path of the sliding mechanism 1 for closing the door panel fixing seat 2; when the sliding mechanism 1 drives the door panel fixing seat 2 to reach the terminal of the moving path, the limiting toggle member 5 contacts the limiting mechanism 3, so that the limiting mechanism 3 drives the door panel fixing seat 2 to move and generate displacement relative to the sliding mechanism 1, so as to realize the coplanar closure of the door panel fixing seat 2.

[0046] The coplanar door track-changing sliding mechanism contacts the limit mechanism 3 through the limit toggle piece 5 to change the state of the limit mechanism 3. The limit mechanism 3 drives the door panel fixing seat 2 to move and produces a displacement relative to the sliding mechanism 1 to achieve the coplanar closure of the door panel fixing seat 2. The mechanism can achieve track change of the door panel fixing seat 2 on a straight track, and can cut the track according to the actual size of the furniture. It is flexible in application, easy to stock, mass-produced, and has low application cost.

[0047] In this embodiment, the sliding mechanism 1 includes a sliding base 11 for achieving displacement of the door panel fixing base 2 and a pulley 111 disposed on the sliding base 11 .

[0048] In addition, the sliding mechanism 1 also includes a guide device 12 for realizing the displacement of the door panel fixing seat 2 relative to the sliding base 11; the guide device 12 includes a guide member 121 arranged on the sliding base 11 and a guide seat 122 slidably connected to the guide member 121, and the guide seat 122 is fixedly connected to the door panel fixing seat 2.

[0049] Therefore, the door panel fixing seat 2 can achieve directional displacement relative to the sliding base 11 through the guide device 12 on the sliding mechanism 1.

[0050] In this embodiment, a synchronization mechanism 4 is further included, and the synchronization mechanism 4 is arranged between the door panel fixing seat 2 and the sliding mechanism 1 to guide the displacement of the door panel fixing seat 2 relative to the sliding mechanism 1. The synchronization mechanism 4 includes a first connecting member 41 having a first rotating end and a first moving end, and a second connecting member 42 having a second rotating end and a second moving end, and the first connecting member 41 is movably connected to the second connecting member 42. The first rotating end is movably connected to the sliding base 11, and the first moving end is slidably connected to the door panel fixing seat 2; the second rotating end is movably connected to the door panel fixing seat 2, and the second moving end is slidably connected to the sliding base 11.

[0051] Specifically, a first sliding groove 45 is provided on the door panel fixing seat 2, a first sliding member 43 is provided on the first movable end, and the first sliding member 43 is slidably connected to the first sliding groove 45; a second sliding groove 46 is provided on the sliding base 11, a second sliding member 44 is provided on the second movable end, and the second sliding member 44 is slidably connected to the second sliding groove 46.

[0052] Alternatively, a first sliding member 43 is provided on the door panel fixing seat 2, a first sliding groove 45 is provided on the first movable end, and the first sliding member 43 is slidably connected to the first sliding groove 45; a second sliding member 44 is provided on the sliding base 11, a second sliding groove 46 is provided on the second movable end, and the second sliding member 44 is slidably connected to the second sliding groove 46.

[0053] Therefore, when the door panel fixing seat 2 is displaced relative to the sliding mechanism 1, the synchronization mechanism 4 guides the displacement of the door panel fixing seat 2 relative to the sliding mechanism 1, so that the door leaves 6 are always in a parallel state.

[0054] In this embodiment, the door panel fixing seat 2 is provided with a connecting hole 21 and a connecting port 22 for connecting the door leaf 6 .

[0055] Figure 6-Figure 7The structure shown is a schematic diagram of the structure of the coplanar door system in which the coplanar door track-changing sliding mechanism using the above-mentioned limiting mechanism is applied to the coplanar door furniture, and it also includes a track 7 supporting the displacement of the sliding mechanism 1. Since the coplanar door track-changing sliding mechanism itself can realize track change, so that the track 7 supporting its displacement does not need to be provided with a curved track for track change, the track 7 can be freely cut according to the actual length requirements when applied to the coplanar door system. The limiting toggle member 5 is arranged at the end of the track 7 of the sliding mechanism 1 for closing the coplanar door; when the sliding mechanism 1 drives the door panel fixing seat 2 to reach the end of the track 7, the limiting toggle member 5 contacts the limiting mechanism 3, so that the limiting mechanism 3 drives the door panel fixing seat 2 to move and generate displacement relative to the sliding mechanism 1, so as to realize the coplanar closing of the coplanar door. The track of the coplanar door system can be cut according to the actual size of the furniture, and the application is flexible, the stocking is convenient, and the mass production is low, and the application cost is low.

[0056] In summary, the limiting mechanism for the coplanar door track-changing sliding mechanism provided by the present invention has the following beneficial effects:

[0057] (i) The limit toggle member 5 contacts the movable limit member 31 to change the state of the movable limit member 31, and the movable limit member 31 rotates relative to the fixed member 34, so that the movable limit member 31 is displaced relative to the limit base 33, thereby realizing the coplanar door track change sliding mechanism through which the track change can be completed on the straight track.

[0058] (ii) When the toggle member 52 contacts the movable limiting member 31, the movable limiting member 31 is driven to rotate, so that the locking member 36 on the movable limiting member 31 overcomes the elasticity of the elastic member 37 and slides out of the locking groove 3311, so that the movable limiting member 31 slides and moves relative to the limiting base 33 along the groove surface after the first arc groove 311 and the second arc groove 322 are connected.

[0059] (III) The movable stopper 31 will be in active contact with the toggle member 52 and the fixed stopper 32 during use. The movable stopper 31 made of plastic can reduce the impact force of the collision during contact and reduce noise.

[0060] (iv) Under the action of the elastic reset member 39 , the movable limit member 31 is facilitated to be smoothly displaced and reset on the limit base 33 .

Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the present invention.
