Description

FIELD

BACKGROUND

[0002] In a sliding shower door of a conventional shower room, in order to reduce collision between a movable door and the doorway and noise therefrom, a buffer is generally mounted on a rail of the sliding shower door to provide buffer for movement of a movable door panel.

[0003] According to a conventional technology, in order to effectively buffer the movable door panel in both directions of opening and closing the door, two dampers are mounted on the rail of the shower door, and the two dampers respectively provide buffer for the movement of the movable door panel in the two directions of opening and closing the door. Since the dampers requires a space for mounting, it is necessary to increase a size of the rail for placing the two dampers. Hence, a structural size of the rail is increased and cost for the shower door is increased.

[0004] Moreover, damping cylinders of the bidirectional damper adopted in the conventional technology are connected in series in an axial direction, resulting in an excessively large size of the damper in a length direction.

[0043] Shower doors in different types of shower rooms have different sizes. A large length is required for mounting conventional buffers in series in an axial direction. There is a need to mount a buffer on a shower door with a small width.

[0044] In view of the above problems, a bidirectional buffer is provided according to the present application.

[0045] Referring to FIG. 1, a bidirectional buffer is provided according to an embodiment of the present application. The bidirectional buffer includes a mounting frame 10, a damper 20, a first slider 30, a second slider 40, a first clamper 51, a second clamper 52 and an elastic device 60.

[0046] For convenience of description, the first clamper 51 and the second clamper 52 are referred to as clamper(s) hereinafter.

[0047] When the bidirectional buffer is mounted on a shower door, the first clamper 51 and the second clamper 52 respectively correspond to a first limiter and a second limiter disposed on a door frame (not shown). The limiters are located on motion paths of the clampers respectively. Generally, as shown in FIG. 1, a first direction refers to a direction of opening or closing the shower door, directing from the center to an edge of the sliding door. A third direction refers to a direction from the shower door to the door frame where the limiters are located. The third direction is perpendicular to the first direction. The second direction is perpendicular to the first direction and the third direction, and points toward a side of the sliding door.

[0048] The mounting frame 10 attaches the damper 20, the first slider 30, the second slider 40, the clampers and the elastic device 60 to the shower door.

[0049] The damper 20 includes at least one group of a damping cylinder 201 and a piston rod 202. A first end of the piston rod 202 is located in the damping cylinder 201, and a second end of the piston rod 202 is reciprocatable in the first direction.

[0050] Two ends of the damper 20 are respectively connected with the first slider 30 and the second slider 40. The damping cylinder 201 is fixedly connected with the first slider 30. The second end of the piston rod 202 is fixedly connected with the second slider 40. Two ends of the elastic device 60 are respectively connected with the first slider 30 and the second slider 40, and the elastic device 60 is in a stretched state, so that the first slider 30 and the second slider 40 can slide along the first direction under a contraction force of the elastic device 60.

[0051] As shown in FIG. 7, the elastic device 60 is arranged on an upper side of the damper 20 in the third direction, so that a tension efficiency when returning the elastic device 60 is increased.

[0052] Further, a clamping opening 504 of each clamper faces the third direction. In the first direction, a movable end of the clamper is away from the damper 20 and is movable in the third direction. The clamper may be made of elastic material to enable expansion and contraction of the clamper.

[0053] In some alternative embodiments, referring to FIG. 2, the mounting frame 10 includes a first frame plate 101, a second frame plate 102 and an upper connecting plate 103, where a main surface of the first frame plate 101 is opposite to a main surface of the second frame plate 102. The first frame plate 101 and the second frame plate 102 are both elongated plates extending along the first direction, and the first frame plate 101 and the second frame plate102 are completely identical in features. During installation, two ends of the first frame plate 101 are respectively connected with two ends of the second frame plate 102, so that the first frame plate 101 and the second frame plate 102 are parallel to each other in the second direction and aligned with each other in the first direction. A top end of the first frame plate 101 and a top end of the second frame plate 102 in the third direction are connected by the upper connecting plate 103.

[0054] A guide rail 106 is provided on each of the first frame plate 101 and the second frame plate102. A sum of a height of the guide rail 106 on the first frame plate 101 and a height of the guide rail 106 on the second frame plate 102 is less than a height of the upper connecting plate 103. The two guide rails 106 on extending sections 1012 extend to the two ends of the first frame plate 101 and the two ends of the second frame plate 102 respectively along the first direction.

[0055] The guide rails 106 are opposite to each other between the first frame plate 101 and the second frame plate 102, and guide the clampers 50 to reciprocate in the first direction. Two guide grooves 108 are formed by the guide rail 106 on the first frame plate 101, the guide rail 106 on the second frame plate 102 and the upper connecting plate 103. The two clampers are in one-to-one correspondence to the two guide grooves 108, and each clamper 50 is slidably mounted in a corresponding one of the guide rails 108.

[0056] Two ends of the extending section 1012 of the guide rail 106 are bent downward along the third direction and form first bending portions 1013, which form two vertical positioning plates 109 on the two ends. An end of the vertical positioning plate 109 away from the extending section 1012 is bent along the first direction and forms a second bending portion 1014. The second bending portion 1014 extends toward the first direction and forms a blocking plate 107.

[0057] After the first frame plate 101 is connected with the second frame plate 102, a mounting cavity 1010 is defined by the upper connecting plate, the extending sections 1012, and the vertical positioning plates 109 which are located between the first frame plate 101 and the second frame plate 102. The first slider 30, the second slider 40, the elastic device 60 and the damper 20 are accommodated in the mounting cavity 1010. In addition, in the mounting cavity 1010, the first slider 30 and the second slider 40 can reciprocate in the first direction.

[0058] In some alternative embodiments, referring to FIG. 2, the mounting frame 10 further includes a lower connecting plate 104. A lower end of the first frame plate 101 and a lower end of the second frame plate 102 in the third direction are connected by the lower connecting plate 104. In this case, the mounting cavity 1010 is defined by the upper connecting plate 103, the lower connecting plate 104, the extending sections 1012 and the vertical positioning plates 109.

[0059] In some alternative embodiments, referring to FIG. 2, an end fixing plate 105 is provided at an end of each of the first frame plate 101 and the second frame plate 102, and the two ends of the first frame plate 101 and the two ends of the second frame plate 102 in the first direction are connected by the end fixing plates 105.

[0060] According to the embodiments of the present application, the first frame plate 101 may be connected with the second frame plate 102 through the upper connecting plate 103, the lower connecting plate 104 and the end fixing plates 105 by welding, riveting or screw.

[0061] Further, the first slider 30 and the second slider 40 are mounted on the mounting frame 10 along the first direction. The two clampers 50 are respectively hinged to the first slider 30 and the second slider 40, so that the clampers 50 are ganged with the first slider 30 and the second slider 40 in a same direction.

[0062] In some alternative embodiments, referring to FIG. 3, the first slider 30 further includes a mounting enclosure portion 301. At least a portion of the damping cylinder 201 is accommodated in the mounting enclosure portion 301 and is fixed to the mounting enclosure portion 301. The second slider 40 further includes a fixing hole 406 corresponding to the piston rod 202. The piston rod 202 is connected with the second slider 40 through the fixing hole 406.

[0063] In some alternative embodiments, the fixing hole 406 is a blind hole, and the piston rod 202 extends into the fixing hole 406 and is in close contact with a hole wall.

[0064] In some alternative embodiments, referring to FIG. 3, the first slider 30 further includes an inner blocking plate 304 and an outer blocking plate 305. An opening 306 is defined on the outer blocking plate 305. The damping cylinder 201 is accommodated between the inner blocking plate 304 and the outer blocking plate 305. The piston rod 202 passes through the opening 306 and is connected with the second slider 40.

[0065] In some alternative embodiments, referring to FIG. 3, the first slider 30 extends in the third direction and forms a first clamping portion 309, and the second slider 40 extends in the third direction and forms a first clamping portion 309. A first hinge hole 3011 along the second direction is defined on the first clamping portion 309, and a second hinge hole 4011 along the second direction is defined on the second clamping portion 409. The first clamper 51 and the second clamper 52 are hinged to the first clamping portion 309 and the second clamping portion 409 respectively through the first hinge hole 3011 and the second hinge hole 4011.

[0066] In some alternative embodiments, referring to FIG. 3, ends of the first clamping plates 308 close to the mounting enclosure portion 301 are bent toward each other to form a first clamping groove 3012, and ends of the second clamping plates 408 close to the fixing hole 406 are bent toward each other to form a second clamping groove 4012. The two ends of the elastic device 60 are fixedly connected with the first clamping groove 3012 and the second clamping groove 4012 respectively.

[0067] In some alternative embodiments, referring to FIG. 5, each clamper includes a sheet clamper body 501, a first clamping tooth 502 and a second clamping tooth 503. The first clamping tooth 502 and the second clamping tooth 503 are arranged at a top end of the clamper body 501 in the third direction, and are distributed in the first direction. The first clamping tooth 502 is arranged on a side of the clamper body 501 close to the center of the mounting frame 10 in the first direction. The second clamping tooth 503 is arranged on a side of the clamper body 501 away from the center of the mounting frame 10 in the first direction. An inclined guide surface 508 is provided on the first clamping tooth 502. A clamping opening 504 is formed between the first clamping tooth 502 and the second clamping tooth 503. The clamping opening 504 extends outside the mounting frame 10 in the third direction.

[0068] Each clamper furthers includes a clamper hinge portion 505. The clamper hinge portion 505 is arranged on the clamper body 501, and is diagonally arranged with the second clamping tooth 503. The clampers are respectively hinged to the first slider 30 and the second slider 40 through the clamper hinge portions 505.

[0069] In some alternative embodiments, referring to FIG. 5, each clamper includes a first guiding member 506 and a second guiding member 507. In the third direction, the first guiding member 506 is located above the guide rail 106, and the second guiding member 507 is located below the guide rail 106, so as to limit the reciprocating sliding of the clamper along the guide rail 106 in the first direction.

[0070] When the movable end 5011 of the clamper moves to the first bending portion 1013 along the first direction, the vertical positioning plate can guide the movable end 5011 of the clamper to move along the third direction, the clamper turns over due to the eccentric force, and the first guiding member 506 contacts a surface of the vertical positioning plate 109, so that the clamping opening 504 of the clamper facing the third direction tilts toward the first direction. Thereby, the clamper is separated from the limiter (not shown), and is guided into the vertical positioning plate 109. The second clamping tooth 503 sinks in the third direction, so that the movable end 5011 of the clamper is positioned between the first bending portion 1013 and the second bending portion 1014.

[0071] When the limiter touches the first clamping tooth, the movable end 5011 of the clamper turns over upward under the action of external force, and the second clamping tooth 503 moves upward in the third direction and is separated from the first bending portion 1013, so that the clamper moves along the first direction.

[0072] In some alternative embodiments, the second clamping tooth 503 is formed by bending a strip, and a tail of the strip is provided with a tail hook 509. A movement cavity 5010 reserved for the tail hook 509 to move in the third direction is defined at a lower portion of the second clamping tooth 503. A limiting piece 5012 is provided at an outer opening of the movement cavity 5010. The tail hook 509 extends into the movement cavity 5010 by bending the strip, and the limiting piece 5012 limits the movement of the tail hook 509 in the movement cavity 5010. When the second clamping tooth 503 contacts the limiter not shown, the tail hook 509 moves in a direction opposite to the third direction in the movement cavity 5010 under the pressure of the limiter. When the limiter is separated from the second clamping tooth 503 and enters the clamping opening 504, the tail hook 509 returns to the original position along the third direction under the inertia.

[0073] The bidirectional buffer and the working principle of the bidirectional buffer are described in reference to FIG. 7.

[0074] The bidirectional buffer according to the embodiments of the present application is mounted on a glass movable shower door. In an embodiment, the first direction is defined to be a direction of closing the shower door and the shower door and the buffer slide together in the first direction. When the shower door and the buffer slide to a door closing end, a second limiter on the rail at the door closing end contacts the second clamper 52 on the shower door, and the movable end 5011 of the clamper 52 turns over upward in the third direction, so that the clamping opening 504 formed by the first clamping tooth 502 and the second clamping tooth 503 clamps the second limiter. The elastic device 60 in a stretching state in the mounting cavity 1010 generates a contraction force in the first direction and pulls the buffer and the movable door to move continuously. While the elastic device 60 automatically closes the door, the damper 20 buffers a sliding speed of the door.

[0075] In a procedure of opening the door, since the limiter is clamped by the clamping opening 504, the second clamper 52 moves to an end of the buffer as the shower door moves in the direction opposite to the first direction, and the elastic device 60 continues to stretch. When the second clamper 52 moves to an end of the guide groove 108, the movable end 5011 of the second clamper 52 moves in the third direction under an action of the vertical positioning plate 109, the second clamper 52 turns over, and the second clamping tooth 503 sinks in the third direction and is positioned at the vertical positioning plate 109, so that the second limiter is separated from the second clamper 52, the second clamper 52 stops performing the limiting function, and the movable door continues to move in the direction opposite to the first direction. When the first limiter at a door opening end contacts the first clamper 51, the first clamper 51 turns over upward, and the second clamping tooth 503 turns over upward in the third direction, so that the clamping opening 504 clamps the first limiter, and the elastic device 60 in the stretching state in the mounting cavity 1010 generates a contraction force in the first direction and pulls the buffer and the movable door to move continuously. The door is slowly opened to an extreme position under the buffer from the damper 20. Therefore, the door can be opened or closed by repeating the steps.

[0076] For example, when the movable end 5011 of the clamper sinks in the third direction and is positioned at the vertical positioning plate 109 as shown in FIG. 7, self-locking is formed between the clamper and the vertical positioning plate 109 under the pulling force of the elastic device 60 and the limiting of the first guiding member 506 and the second guiding member 507, so that movement in the first direction is not allowed.

[0077] In the buffer and the shower door including the same according to the embodiments of the present application, the damper, the first clamper, and the second clamper arranged in the first direction, and the two clampers are connected with the two end of the damper through the elastic device. Thereby, an energy loss in reset of the elastic device is reduced, the buffer is enabled to achieve bidirectional automatic opening and closing of a door in the first direction by using only one damper.

[0078] Embodiments of the present application are described above. However, the protection scope of the present application is not limited thereto. Changes and substitutions readily obtained by those skilled in the art within the technical scope disclosed in the present application should fall within the protection scope of the present application.
