Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of bathroom equipment, and in particular, to a track assembly for a shower door and a shower room comprising the same. BACKGROUND

[0002] Nowadays, people usually set a shower door in the bathroom when decorating. Generally, the bathroom is shown as a rectangle in the plan view, and the bathroom is usually separated into a dry area and a wet area by a shower door at the middle position of the rectangle.

[0003] The shower door can be a combination of one fixed door and one movable door, or a combination of multiple fixed doors and multiple movable doors. In order to increase the applicability in actual use, two movable doors are usually selected and installed in a form of mutual sliding, so that the user can enter the shower room from the left side or the right side without being restricted by the space.

[0004] Most of the existing double movable doors are provided with two sliding grooves on the track, and one door panel is installed in each sliding groove. The door panels slide in the respective sliding grooves and do not interfere with each other. However, a large size track is required to simultaneously realize the two sliding grooves. Such a design will cause a large amount of material consumption, which is contrary to the current environmental protection concept.

[0005] In addition, in order to prevent the movable door from colliding with the wall surface with great force when closing, a closer is usually provided on the track. The existing technology is to install the closer under the track, and a jump-proof piece is provided under the track to prevent the roller connected with the door panel from being separated from the track. The jump-proof piece can also cooperate with the closer to achieve door closing buffering. However, the closer and the jump-proof piece provided under the track will obviously affect the appearance of the shower door.

[0006] Therefore, there is an urgent need for a track assembly with a roller anti-separation device and a hidden closer, which can save materials and achieve an aesthetic and simple appearance in the actual application of the shower door. CONTENT OF THE INVENTION

[0007] To solve the above problems, the main aspect of the present disclosure provides a track assembly for a shower door, which comprises at least one roller assembly, at least one closer, and a track arranged in a first direction, wherein the roller assembly comprises a roller and an anti-derailing member, the roller is accommodated in the anti-derailing member and is seated above the track through the anti-derailing member to reciprocate on the track in the first direction, the anti-derailing member is formed with a limiting block protruding towards the track in a second direction, and the second direction is perpendicular to the first direction; the track is formed with a first accommodating cavity extending in the first direction along the length of the track and a limiting edge, the first accommodating cavity has an upward opening, and the limiting edge is arranged on both sides of the opening in a third direction and partially covers the opening, and the third direction is perpendicular to the first direction and the second direction; the closer is entirely hidden in the first accommodating cavity, the limiting block extends into the first accommodating cavity and can be engaged with the limiting edge to prevent the roller assembly from derailing from the track, and the limiting block is adapted to be engaged with the closer to provide a buffering force; and the roller is only in rolling contact with the limiting edge of the track.

[0062] For ease of description and understanding, please refer to Figure 1 The installation location shown in the figure indicates the direction of the moving door's movement (opening or closing direction, i.e.) in this disclosure. Figure 1 The horizontal direction in the installation state is defined as the first direction, the vertical direction (i.e., the up and down direction) in the installation state is defined as the second direction, the first direction is perpendicular to the second direction, and the direction perpendicular to the first direction and the second direction is defined as the third direction.

[0063] This disclosure provides a track assembly for a shower door, comprising a roller assembly, a closer, and a track. The roller assembly includes an anti-derailment element to prevent the door from detaching from the track. A concealed closer is provided between the roller assembly and the track, ensuring both the aesthetics of the shower door and preventing the door from sliding too quickly and causing an impact, thereby improving user satisfaction.

[0064] The following embodiments of the present disclosure exemplarily show a track assembly for a shower door, such as Figures 1 to 11 The track assembly can be installed in a position corresponding to the top end of the movable door along a first direction, as Figure 1 The track assembly can be installed in a position corresponding to the top end of the movable door along a first direction, as Figure 2 The track assembly includes a roller assembly 10, a closer 20 and a track 30, as

[0065] The closer 20 can be completely accommodated in a first accommodating cavity 304 of the track 30, so that the closer 20 is entirely hidden in the first accommodating cavity 304, and the closer 20 is installed at a position close to a track end face 306 or a track end face 307 of either end of the track 30, as Figure 2 and Figure 5a The closer 20 can be completely accommodated in a first accommodating cavity 304 of the track 30, so that the closer 20 is entirely hidden in the first accommodating cavity 304, and the closer 20 is installed at a position close to a track end face 306 or a track end face 307 of either end of the track 30, as

[0066] The roller assembly 10 includes a roller 101, an anti-derailing piece 102, an anti-rotation piece 103, a pressing piece 104 and an eccentric fastener 105, as Figure 3 The roller assembly 10 includes a roller 101, an anti-derailing piece 102, an anti-rotation piece 103, a pressing piece 104 and an eccentric fastener 105, as Figure 4 The roller 101 is accommodated in the anti-derailing piece 102 and is seated above the track 30 through the anti-derailing piece 102, so as to reciprocate along the first direction on the track 30, so that the movable door can be reciprocally slid along the first direction on the track 30 through the roller 101. The anti-derailing piece 102 is formed with a limiting block 1021 protruding towards the track 30 along a second direction, for cooperating with the track 30 to prevent the roller assembly 10 from derailing from the track 30, and the limiting block 1021 is adapted to engage with the closer 20 to enable the closer 20 to provide a buffering force.

[0067] The track 30 has a length greater than the size of the movable door in the first direction, and the length of the track 30 can be adjusted according to actual application. The track end face 306 and the track end face 307 of the track 30 can be fixedly installed between the two walls and / or the fixed frame of the shower room by, for example, adhesion, threaded connection and the like.

[0068] The track assembly can be installed in a position corresponding to the top end of the movable door along a first direction, as Figure 5a , Figure 5bAs shown, the track 30 has load-bearing plates 301 and 302 spaced apart and parallel to each other in a second direction. The bottoms of the load-bearing plates 301 and 302 are connected by a bottom connecting plate 303, thereby forming a first receiving cavity 304 with a top opening, which is used to receive the closure device 20, and the limiting block 1021 of the anti-derailment member 102 also extends into the first receiving cavity 304. The tops of the load-bearing plates 301 and 302 are also formed with limiting edges 305. The limiting edges 305 partially cover the openings of the first receiving cavity 304 from both sides, providing a track for the roller 101 to roll and engaging with the limiting block 1021 to prevent the roller assembly 10 from disengaging from the track 30.

[0069] like Figure 6 As shown, preferably, the roller 101 is generally cylindrical in shape, slightly thicker in the middle and slightly thinner at both ends. The diameter of its outer circumferential surface decreases from the center to both ends, and a first central hole 1011 is formed through it along the central axis. A roller end face 1012 protrudes from the first central hole 1011 along its circumference. Correspondingly, as... Figure 4 As shown, the upper surface of the limiting edge 305 is concave in shape and recesses into the first receiving cavity 304, thereby more stably supporting the roller 101 and making rolling contact with the roller 101. It can be understood that the roller 101 can be formed into a cylindrical shape, and the limiting edge 305 can be formed into a flat surface.

[0070] like Figure 7 As shown, a second receiving cavity 1027 is formed inside the main body of the anti-derailment component 102 for accommodating the roller 101. The second receiving cavity 1027 is surrounded by a circumferential surface and a baffle 1029, and thus, the second receiving cavity 1027 has an opening facing the track 30 in the installed state to facilitate the installation of the roller 101. In addition, a second central hole 10210 is provided at the center of the baffle 1029 for assembling the roller assembly 10. The second receiving cavity 1027 has two openings spaced apart at the bottom on its circumferential surface. The roller 101 rolls in contact with the limiting edges 305 on both sides of the track 30 through the two openings. Alternatively, the axial dimension of the second receiving cavity 1027 is smaller than the axial dimension of the roller 101, such that the outer edge of the roller 101 near the opening side of the second receiving cavity 1027 extends out of the anti-derailment member 102 and contacts the track 30. The circumferential surface of the second receiving cavity 1027 has an opening 1028 at the bottom and on the opposite side from the opening side, such that the outer edge of the roller 101 contacts the track 30 through the opening 1028 on the other side. The bottom of the second receiving cavity 1027 also has a protruding stepped portion 1026, which is adjacent to the opening 1028 and parallel to the track 30 in a first direction.

[0071] The anti-derailing piece 102 further comprises a stepped portion 1026 extending downwardly from the lower surface of the body of the anti-derailing piece 102 along the second direction by a first length. The limiting block 1021 is composed of a main body portion 1022 and a limiting boss 1023. The main body portion 1022 extends downwardly from the lower surface of the stepped portion 1026 along the second direction by a second length, and the center of the main body portion 1022 has a first through hole 1025. The limiting boss 1023 protrudes on both sides of the main body portion 1022 in the third direction, and the limiting boss 1023 is formed with a guide slope 1024 that narrows downwardly. Optionally, the limiting block 1021 is integrally made of elastic material, and optionally, the anti-derailing piece 102 is integrally made of elastic material.

[0072] During installation, the guide slope 1024 of the limiting block 1021 contacts the edge of the limiting edge 305 facing the first accommodating cavity 304, and the limiting boss 1023 on both sides of the main body portion 1022 is compressed toward the first through hole 1025 under the action of an external force, and is guided by the guide slope 1024 to extend into the first accommodating cavity 304 of the track 30. The sizes of the stepped portion 1026 and the limiting boss 1023 are configured such that the limiting boss 1023 and the stepped portion 1026 can pass through the opening defined between the limiting edges 305 by compressing the limiting boss 1023, the stepped portion 1026 is accommodated in the opening, and the limiting block 1021 fully enters the first accommodating cavity 304 and then rebounds to restore the original size.

[0073] Thus, in the installed state, the limiting block 1021 extends into the first accommodating cavity 304 of the track 30, and when the roller assembly 10 is displaced upwardly, the limiting boss 1023 abuts against the bottom surface of the limiting edge 305 of the track 30, so that the roller assembly 10 is hooked on the limiting edge 305 of the track 30 by means of the limiting block 1021 on the anti-derailing piece 102, preventing the roller assembly 10 from disengaging from the track 30.

[0074] As Figure 4 As clearly shown, the size of the anti-derailing piece 102 is configured such that, in normal operation, a gap is left between the limiting boss 1023 and the lower surface of the limiting edge 305, which is small enough so that there is substantially no frictional resistance between the limiting boss 1023 and the lower surface of the limiting edge 305; once the roller assembly 10 jumps upwardly, the limiting boss 1023 abuts against the lower surface of the limiting edge 305, thereby preventing the roller assembly from disengaging from the track.

[0075] The baffle 1029 of the anti-derailing piece 102 has a stepped first counterbore 10211 on the side facing away from the second accommodating cavity 1027, and the inner circumferential wall of the first counterbore 10211 has a protrusion 10212 for cooperating with the anti-rotation piece 103.

[0076] As Figure 8As shown, the anti-rotation member 103 may include, for example, a disc-shaped seat portion 1031 (corresponding to the first seat portion). The seat portion 1031 has a bottom surface 1035 and an anti-rotation notch 1032 formed at its outer edge for engaging with the protruding teeth 10212 of the anti-derailment member 102. The anti-rotation member 103 has a circular first step 1033 on the side of the seat portion 1031 opposite to the bottom surface 1035. A protruding hollow shaft 1034 is formed axially at the center of the first step 1033. A second through hole 1036 is formed axially at the center of the hollow shaft 1034. The second through hole 1036 has an internal thread and penetrates the anti-rotation member 103.

[0077] During installation, the hollow shaft 1034 passes through the second center hole 10210 of the anti-derailment component 102, extends into the first center hole 1011 of the roller 101, and contacts the roller 101. The first countersunk hole 10211 of the anti-derailment component 102 can accommodate the seat 1031 and the first step 1033 of the anti-rotation component 103. The protruding teeth 10212 engage with the anti-rotation notch 1032 of the anti-rotation component 103, thereby preventing relative rotation between the anti-rotation component 103 and the anti-derailment component 102.

[0078] The anti-rotation component of this application is not limited to the above-described form, but can be replaced by other shapes and structures that can be conceived by those skilled in the art to achieve the same effect of preventing relative rotation between the anti-rotation component 103 and the anti-derailment component 102. For example, the shapes of the seat portion 1031 and the first countersunk hole 10211 can be paired non-circular shapes.

[0079] like Figure 9 As shown, the clamping member 104 is provided with a disc-shaped seat portion 1041 (corresponding to the second seat portion). The seat portion 1041 has a clamping surface 1043, on which a fixing screw 1042 protruding axially is formed.

[0080] During installation, the fixing screw 1042 extends into the second through hole 1036 of the anti-rotation member 103 through the first center hole 1011 of the roller 101, so that the clamping member 104 is threadedly connected to the anti-rotation member 103; the clamping surface 1043 abuts against the roller end face 1012 of the roller 101 facing the opening side of the first receiving cavity 304.

[0081] like Figure 10 As shown, the eccentric fastener 105 can similarly include a disc-shaped seat 1051 (corresponding to the third seat), an eccentric shaft 1054, and a central threaded hole, i.e., a third through hole 1052, penetrating the seat 1051 and the eccentric shaft 1054, wherein the central axis of the eccentric shaft 1054 is offset from the central axis of the seat 1051 and the third through hole 1052. A second countersunk hole 1053 is also formed at the center of the bottom surface of the seat 1051 (i.e., the side facing away from the shower door). Figure 4As shown, the countersunk screw or bolt as the locking member can be screwed into the threaded hole 1052 and 1036 via the second countersink 1053 for fixing and eccentrically adjusting the installation height of the shower door.

[0082] During installation, the eccentric shaft portion 1054 is inserted into the installation hole of the movable door from the side of the movable door opposite to the rail 30, at this time the top surface of the eccentric fastener 105, i.e. the side with the eccentric shaft portion 1054, is in contact with one side of the movable door. The anti-rotation member 103 is placed on the installation hole from the side of the movable door facing the rail 30, and the locking member, such as a countersunk bolt, is screwed into the second through hole 1036 of the anti-rotation member 103 through the through hole 1052 of the eccentric shaft portion 1054 to lock the roller assembly 10, while allowing the installation height of the movable door to be adjusted by rotating the eccentric fastener 105. As shown, Figure 4 As shown, the rollers are mounted on the hollow shaft, for example, by a ball bearing and can rotate around the hollow shaft.

[0083] As shown, Figure 11 As shown, the two ends of the closer 20 have fourth through holes 203, and the closer 20 can be fixedly installed on the bottom connecting plate 303 at the bottom of the rail 30 by using, for example, a threaded connection through the fourth through holes 203. The preferred solution is that, as shown, Figure 5b As shown, the load-bearing plate 301 and the load-bearing plate 302 of the rail 30 are formed with a limiting partition plate 308 extending inwardly along the third direction adjacent to the bottom connecting plate 303, the limiting partition plate 308, the load-bearing plate 301, the load-bearing plate 302 and the limiting edge 305 jointly define a first accommodating cavity 304, and the limiting partition plate 308, the load-bearing plate 301, the load-bearing plate 302 and the bottom connecting plate 303 jointly define an installation groove 309 below the first accommodating cavity 304, and the installation groove 309 is provided with a nut 204 for installation and fixation of the closer 20 in the first accommodating cavity 304. The screw is combined with the nut 204 through the fourth through hole 203 of the closer 20, so as to fix the closer 20 on the bottom connecting plate 303 of the rail 30. By loosening and tightening the screw, the position of the closer 20 relative to the rail 30 can be conveniently adjusted.

[0084] The closer 20 comprises a clamping member 201 and a damper 202 connected to the clamping member 201, and the clamping member 201 is arranged closer to the longitudinal end of the rail 30 than the damper 202, and the clamping member 201 is adapted to be clamped with the limiting block 1021 to transmit the force from the damper 202 to the roller assembly 10.

[0085] The closer 20 comprises a clamping member 201, a damper 202, a sliding groove 205, a guide cavity 2011 and a connecting arm (not shown). The clamping member 201 has a tabular body 207 which is accommodated in the sliding groove 205 so that the clamping member 201 can reciprocate in the sliding groove 205 in a first direction. The damper 202 is accommodated in the guide cavity 2011 and comprises a damping cylinder and a damping rod (not shown) which is retracted into the damping cylinder when the door is closed and is stretched out of the damping cylinder when the door is opened. The clamping member 201 is arranged opposite to the damping rod of the damper 202 and is connected to the damping rod of the damper 202 via the connecting arm. One end of the connecting arm is hinged to a hinge portion (not shown) of the clamping member 201 and the other end is hinged to an end of the damping rod which is away from the damping cylinder. The guide cavity 2011 can restrict the reciprocation of the connecting arm in the first direction. When the closer 20 is installed to the track 30, the end of the closer 20 which is close to the clamping member 201 is closer to the track end surface of the track 30 than the end of the closer 20 which is close to the damper 202.

[0086] The sliding groove 205 is provided with a sunken step 206 vertically downward in a second direction at the end close to the damper 202. The two ends of the clamping member 201 are respectively provided with a first clamping tooth 208 and a second clamping tooth 209 which are upwardly protruded. When the clamping member 201 slides to the sunken step 206, the second clamping tooth 209 close to the damper 202 of the clamping member 201 is sunken downward, and at this time, the clamping effect of the clamping member 201 is released. When the clamping member 201 slides away from the sunken step 206, the second clamping tooth 209 close to the damper 202 of the clamping member 201 is upwardly turned, and the first clamping tooth 208 and the second clamping tooth 209 form a clamping opening thereby.

[0087] The closer 20 further comprises a spring 2010 which is arranged below the clamping member 201 and the damper 202 and is positioned not on the movement path of the clamping member 201 and the damper 202. The active end of the spring 2010 is connected to the clamping opening of the connecting arm to be connected to the clamping member 201, and thus the active end of the spring 2010 can reciprocate with the clamping member 201, so as to realize different stretching states of the spring 2010.

[0088] When the movable door is closed to one side by external force, the movable door drives the rollers 101 to approach the track end face. After the movable door slides to a certain position, the limiting block 1021 of the anti-derailing piece 102 pushes the first clamping tooth 208 of the clamping piece 201, so that the second clamping tooth 209 is lifted upward and separated from the sunken step 206, the clamping piece 201 is clamped with the limiting block 1021, so that the movable door drives the clamping piece 201 to move synchronously. The movement of the clamping piece 201 is transmitted to the damping rod of the damper 202 via the connecting arm, so that the damping rod of the damper 202 is pushed towards the damping cylinder, so that the damper 202 can absorb part of the kinetic energy to slow down the sliding of the door. At the same time, the movement of the clamping piece 201 is transmitted to the movable end of the spring 2010, so that the spring 2010 in the stretched state is retracted, at this time the movable door can be driven to close by itself under the action of the spring 2010. When the movable door moves reversely (opens), the limiting block 1021 pulls the clamping piece 201 back under the action of the movable door, and drives the damping rod and the spring to elongate outward via the connecting arm, until the clamping piece 201 slides to the sunken step 206 and flips over, the second clamping tooth 209 sinks downward, at this time the clamping effect of the clamping piece 201 is released, the clamping piece 201 stops moving at the sunken step 206, and the damping rod and the spring are in the longest stretched state, and the movable door can drive the rollers 101 to continue to move.

[0089] The present disclosure also provides a shower room comprising the above track assembly, which allows two movable doors to be arranged on opposite sides of the track in the third direction respectively, and the two movable doors share one track. The rollers of the two movable doors are arranged alternately on the track, so that one roller of one movable door is arranged between two rollers of the other movable door and can roll between the two rollers, which can realize the left and right sliding of the movable doors and reduce the number of tracks, thereby saving the material of the track and saving the cost.

[0090] The above is only a specific implementation of the embodiments of the present disclosure, but the protection scope of the embodiments of the present disclosure is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the embodiments of the present disclosure, which should be covered within the protection scope of the embodiments of the present disclosure. Therefore, the protection scope of the embodiments of the present disclosure should be subject to the protection scope of the claims.
