Description

Technical Field

[0001] The invention belongs to the technical field of furniture, and in particular relates to a furniture deformation unit and a deformation chair. Background Art

[0002] A transformable chair is a chair that can be transformed into different shapes according to different needs, so that the chair can be used for lying or sitting. The transformable chair can also have many lying and sitting modes. At the same time, the transformable chair can be stored by reducing its volume through deformation.

[0003] The current deformable chair realizes deformation in different states by combining a plate frame structure with a connecting rod structure. Since the plate frame structure and the connecting rod structure are generally made of wood or steel, a cushion is added to the seat of the chair to make it feel comfortable to sit on. However, the cushion is only added to the non-deformed part, and no cushion is added to other parts, so the comfort is limited. For example, Patent 201920402242.1 and Patent 201120122067.4.

[0004] As people's demand for personalized furniture styles increases, the demand for chairs of various shapes increases, such as Fig.21 As shown, the shapes of the four types of chairs in the figure are fixed. Traditional deformable chairs cannot freely transform and switch between the four types, and the degree of deformation is limited.

[0005] If the deformable chair can be deformed and switched according to the above four states and the entire deformable chair is wrapped with a layer, after it is deformed, the layer on the concave side will inevitably become loose while the layer on the convex side will become tight and deformed. In order to avoid the layer from becoming loose on the concave side and becoming tight and deformed on the convex side, an elastic layer can be selected. If the convex side is kept tight for a long time, after the next deformation, the layer on the original convex side will become loose and unable to be tightened due to the weakened elasticity.

[0006] The present invention designs a furniture deformation unit for producing a deformable chair, so that the deformable chair can achieve the above four deformations.

[0007] The present invention designs a furniture deformation unit and a deformation chair to solve the above problems. Summary of the invention

[0008] Based on this, it is necessary to provide a furniture deformation unit and a deformation chair for the problems existing in the current deformation chair. The deformation chair composed of the deformation unit in the present invention can be deformed into no less than four forms to meet the needs of different people for lying and sitting. At the same time, the deformation chair in the present invention can be stored in a roll, which effectively reduces the storage space. The present invention can cover the entire surface of the deformation chair by a covering layer to improve the comfort of the deformation chair. The covering cloth of the outer covering layer of the deformation chair in the present invention is segmented and connected by a connecting cloth. The cloth net in contact with the human body and the cloth net on the back of the connecting cloth are connected by a plurality of first pulling ropes. When the cloth net on one side is stretched and deformed due to the convex longitudinal elongation, the cloth net on the other side is pulled by the first pulling ropes on both sides to shrink and deform inwardly and will not relax. The cloth net on the convex side is stretched and deformed longitudinally, but only the mesh is deformed instead of the elastic deformation of the material itself. Therefore, there is no situation where the elasticity of the cloth net on the convex side is weakened due to being stretched for a long time, which ensures that the cloth net on the convex side can shrink inwardly and will not relax when it becomes the concave side under the pulling of the first pulling ropes on both sides.

The transmission ratio is 1:1, and the transmission ratio of the 21st gear 511 to the 22nd gear 603 is 1:1, which ensures that the second plane frame 201 and the fourth plane frame 401 have the same swing amplitude relative to the first plane frame 101, the third plane frame 301 and the first plane frame 101 have the same swing amplitude relative to the second plane frame 201, the first plane frame 101 and the fifth plane frame 501 have the same swing amplitude relative to the fourth plane frame 401, and the sixth plane frame 601 and the fourth plane frame 401 have the same swing amplitude relative to the fifth plane frame 501.

[0076] like Fig.14 , 15 As shown in FIG. 16 , a deformable chair comprises six deformable units, and the six deformable units are connected in series to form a deformable skeleton, wherein the third plane frame 301 in the deformable unit is fixedly connected to the sixth plane frame 601 in the adjacent deformable unit, and the overall width of the fixedly connected sixth plane frame 601 and the third plane frame 301 is equal to the width of the first plane frame 101, and the surface layer of the deformable skeleton is provided with a cladding 700.

[0077] In a further embodiment, Figure 16-20 As shown, the cover 700 includes a cover cloth 701, and the cover cloth 701 is divided into multiple segments. The cover cloth 701 is filled with sponge. The cover cloth 701 is evenly provided with pull round buttons 706 on the body-fitting side and the back side. The pull round buttons 706 on the body-fitting side of the cover cloth 701 correspond to the pull round buttons 706 on the back side one by one. The pull round buttons 706 on the body-fitting side of the cover cloth 701 are connected to the corresponding pull round buttons 706 on the back side through a second pull rope 707. Adjacent sections of the cover cloth 701 are connected by connecting cloth 707. 02 connection, the connecting cloth 702 includes two cloth nets 703 connecting the segments of the covering cloth 701, the two cloth nets 703 are respectively located on the body-friendly side and the back side of the covering cloth 701, the mesh of the cloth net 703 is diamond-shaped, the two sides of the two cloth nets 703 are connected by a plurality of first pulling ropes 704, the ends of the first pulling ropes 704 are connected to a corner of the mesh of the cloth net 703, and two linings 705 are bonded to the covering cloth 701 for shielding and dustproofing the gaps between the first pulling ropes 704 on both sides of the cloth net 703.

[0078] The deformable chair composed of the deformation units of the present invention can be deformed into no less than four forms to meet the needs of different people for lying and sitting. At the same time, the deformable chair of the present invention can be stored in a roll, which effectively reduces the storage space. The present invention can cover the entire surface of the deformable chair with the covering layer 700 to improve the comfort of the deformable chair. In the present invention, the covering cloth 701 of the outer layer 700 of the deformable chair is in the shape of segments connected by connecting cloth 702, and the cloth net 703 on the connecting cloth 702 that contacts the human body and the cloth net 703 on the back are connected by a plurality of first pulling ropes 704. When the cloth net 703 on one side is tightened due to the convex longitudinal elongation deformation, the cloth net 703 on the other side undergoes inward transverse contraction and deformation without loosening under the pulling of the first pulling ropes 704 on both sides. The cloth net 703 on the convex side that is longitudinally elongated, deformed and tightened only has its mesh deformed but the material itself does not undergo elastic deformation. Therefore, there is no situation where the elasticity of the cloth net 703 on the convex side is weakened due to being stretched for a long time, thereby ensuring that the cloth net 703 on the convex side can be laterally contracted without loosening under the pulling of the first pulling ropes 704 on both sides when it becomes the concave side.

[0079] The operation process of the present invention is as follows:

[0080] In the initial state, the deformation unit is in a straight state, the third block 112 on the outer wall of the first ring sleeve 110 is disengaged from the fifth groove 137 on the inner wall of the worm gear 123 and is inserted into the first groove 109 on the inner wall of the first gear 108, the first block 104 on the second round pin 103 is inserted into the second groove 111 on the inner wall of the first ring sleeve 110, the fourth block 116 and the fifth block 117 on the outer wall of the second ring sleeve 114 are respectively inserted into the fifth groove 137 on the inner wall of the worm gear 123 and the fourth groove 136 on the inner wall of the second gear 118, the third groove 115 on the inner wall of the second ring sleeve 114 is disengaged from the second block 105 on the second round pin 103, and the worm gear 123 and worm 125 have a self-locking function.

[0081] like Figure 3As shown, when the deformation unit needs to be bent, the twist wheel 129 is rotated, and the twist wheel 129 drives the fourth plane frame 401 to swing a certain angle relative to the first plane frame 101 around the central axis of the second round pin 103 through the first rotating shaft 128, the fourth gear 127, the third gear 126, the worm 125, the worm wheel 123 and the connecting rod 404, and the worm wheel 123 drives the second ring sleeve 114 to rotate relative to the second round pin 103 through the fourth clamping block 116, and the second ring sleeve 114 drives the second gear 118 to rotate synchronously by a certain angle through the fifth clamping block 117, and the second gear 118 drives the second gear 118 to rotate synchronously by a certain angle through the fifth gear 118. 132, the first shaft sleeve 131, the sixth gear 133 and the seventh gear 134 drive the second rotating shaft 135 to rotate relative to the first planar frame 101, and the second rotating shaft 135 drives the second planar frame 201 to swing relative to the first planar frame 101 around the central axis of the third round pin 202 by a certain angle through the eighth gear 138 and the tenth gear 203, and the swing angle of the second planar frame 201 relative to the first planar frame 101 is equal to the swing angle of the fourth planar frame 401 relative to the first planar frame 101, and the second planar frame 201 and the fourth planar frame 401 swing towards each other relative to the first planar frame 101.

[0082] The ninth gear 139 drives the third planar frame 301 to swing a certain angle relative to the second planar frame 201 around the central axis of the fourth round pin 302 through the eleventh gear 205, the third rotating shaft 204, the twelfth gear 206 and the thirteenth gear 303. The swing angle of the third planar frame 301 relative to the second planar frame 201 is equal to the swing angle of the second planar frame 201 relative to the first planar frame 101. The first planar frame 101 and the third planar frame 301 swing towards each other relative to the second planar frame 201.

[0083] The fourteenth gear 406 rotates under the action of the first gear 108, and the fourteenth gear 406 drives the fifth planar frame 501 to swing at a certain angle relative to the fourth planar frame 401 around the central axis of the fifth round pin 503 through the fourth rotating shaft 407, the fifteenth gear 408 and the seventeenth gear 505. The fifth planar frame 501 and the first planar frame 101 swing towards each other at the same angle relative to the fourth planar frame 401.

[0084] The sixteenth gear 409 drives the sixth planar frame 601 to swing relative to the fifth planar frame 501 around the central axis of the sixth round pin 602 at a certain angle through the eighteenth gear 506, the fifth rotating shaft 507, the nineteenth gear 508, the twentieth gear 509, the second shaft sleeve 510, the twenty-first gear 511 and the twenty-second gear 603, and the sixth planar frame 601 and the fifth planar frame 501 swing towards each other at the same angle relative to the fifth planar frame 501.

[0085] like Figure 2As shown, when the deformation unit needs to be bent straight, the driving rod 121 is pulled axially along the second round pin 103 by a certain amplitude through the lever 122, and the driving rod 121 drives the second ring sleeve 114 to move axially relative to the second round pin 103 by a certain amplitude through the fourth rotating sleeve 120, and the second ring sleeve 114 drives the first ring sleeve 110 to move axially synchronously by the same distance through the second rotating sleeve 113, and the fourth clamping block 116 on the outer wall of the second ring sleeve 114 disengages from the fifth clamping groove 137 on the inner wall of the worm gear 123, and the second ring sleeve 114 on the second round pin 103 is moved axially by a certain amplitude. The block 105 enters the third slot 115 on the inner wall of the second ring sleeve 114, the fifth block 117 on the outer wall of the second ring sleeve 114 is still inserted into the fourth slot 136 on the inner wall of the second gear 118, the second slot 111 on the inner wall of the first ring sleeve 110 is separated from the first block 104 on the second round pin 103, the third block 112 on the outer wall of the first ring sleeve 110 is inserted into the fifth slot 137 on the inner wall of the worm gear 123, and the third block 112 on the outer wall of the first ring sleeve 110 is still inserted into the first slot 109 on the inner wall of the first gear 108.

[0086] The twist wheel 129 is rotated, and the twist wheel 129 drives the fourth planar frame 401 to swing a certain angle relative to the first planar frame 101 around the central axis of the second round pin 103 through the first rotating shaft 128, the fourth gear 127, the third gear 126, the worm 125, the worm wheel 123 and the connecting rod 404. The second ring sleeve 114 does not rotate relative to the second round pin 103, the second gear 118 does not rotate relative to the second round pin 103, the second gear 118 does not drive the second rotating shaft 135 to rotate relative to the first planar frame 101, the second rotating shaft 135 does not drive the second planar frame 201 to swing around the third round pin 202 relative to the first planar frame 101 through a series of transmissions, and the eighth gear 138 does not drive the third planar frame 301 to swing around the central axis of the fourth round pin 302 relative to the second planar frame 201 through a series of transmissions.

[0087] The worm gear 123 drives the first ring sleeve 110 to rotate relative to the second round pin 103 through the third clamping block 112, and the first ring sleeve 110 drives the first gear 108 to rotate a certain angle through the third clamping block 112, and the rotation angle of the first gear 108 is equal to the rotation angle of the worm gear 123, the fourteenth gear 406 is stationary relative to the first gear 108 and does not rotate, the fourteenth gear 406 will not drive the fifth plane frame 501 to swing around the fifth round pin 503 relative to the fourth plane frame 401 through a series of transmissions, and the sixteenth gear 409 will not drive the sixth plane frame 601 to swing around the central axis of the sixth round pin 602 relative to the fifth plane frame 501 through a series of transmissions.

[0088] The second planar frame 201 and the third planar frame 301 are stationary relative to the first planar frame 101 and are in a straight state. The fourth planar frame 401, the fifth planar frame 501 and the sixth planar frame 601 are in a straight state and swing a certain angle relative to the first planar frame, thereby completing the straight bending of the deformation unit around the central axis of the first round pin 102 or the second round pin 103 at a certain angle.

[0089] After the deformation unit is completely deformed, the deformed shape of the deformation unit can be effectively maintained because the worm wheel 123 and the worm 125 have a self-locking function.

[0090] The cladding 700 of the Transformable Chair changes during its transformation as follows:

[0091] like Fig. 20 As shown, the covering cloth 701 on the curved convex side of the deformable chair is tightened, and the covering cloth 701 segments move in opposite directions and longitudinally stretch the cloth net 703 of the connecting cloth 702 connecting the covering cloth 701 segments. The cloth net 703 on the convex side pulls the cloth net 703 on the curved concave side through the second pulling ropes 707 on both sides thereof due to the longitudinal stretching, so that the cloth net 703 on the concave side is transversely stretched to cause the cloth net 703 to shrink longitudinally, thereby preventing the covering cloth 701 on the concave side from loosening.
