Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

As shown in fig. 1, fig. 1 is a schematic perspective view of a slide rail assembly 100 according to an embodiment of the present application. The slide rail assembly 100 can be used on telescopically deformable furniture. Wherein, the furniture which can be telescopically deformed can be a cabinet 200, a shoe cabinet or a bookshelf and the like, and the furniture can be extended and compressed along the horizontal direction, so that the space size of the internal cavity of the furniture is changed. Referring to fig. 4, fig. 4 is a schematic perspective view of a piece of furniture according to an embodiment of the present application, and in particular, a cabinet 200 is taken as an example to illustrate the piece of furniture, which includes the sliding rail assembly 100 shown in fig. 1. The furniture includes a first sidewall 210, a second sidewall 220, and a slide rail assembly 100 connecting the first sidewall 210 and the second sidewall 220. The sliding rail assembly 100 can be extended and retracted along a horizontal direction, so that the first side wall 210 can be close to or far away from the second side wall 220 to achieve the extension and retraction of the furniture, and further change the space size of the internal cavity of the furniture.

The following describes the specific structure of the sliding rail assembly 100 and the furniture, and the specific structure of the furniture is described by taking the cabinet 200 as an example.

As shown in fig. 1, the slide rail assembly 100 includes a telescopic rod unit 110, a connection unit 120, and a hanger rail unit 130. The telescopic rod unit 110 serves as a support body and serves as a framework in the entire slide rail assembly 100. The hanger rail unit 130 is connected to the telescopic rod unit 110 through the connection unit 120, and when the telescopic rod unit 110 performs a telescopic motion, the hanger rail unit 130 is driven by the connection unit 120 to move synchronously, so that the hanger rail unit 130 can also perform a telescopic motion.

The telescopic rod unit 110 includes a first rod 111 and a second rod 112, and the first rod 111 is slidably connected to the second rod 112. For example, the first rod 111 and the second rod 112 are both of a sleeve structure, and the second rod 112 can be inserted into the inner cavity of the first rod 111, so as to extend and retract the telescopic rod unit 110.

The connection unit 120 includes a first connection member 121 and a second connection member 122. The first connecting member 121 is connected to the first rod 111, and the second connecting member 122 is connected to the second rod 112.

The hanger rail unit 130 includes a first hanger rail 131 and a second hanger rail 132, the first hanger rail 131 being connected to the first connector 121, and the second hanger rail 132 being connected to the second connector 122.

Since the first link 121 connects the first rod 111 and the first hanging rail 131, and the second link 122 connects the second rod 112 and the second hanging rail 132, when the first rod 111 slides relative to the second rod 112, the first hanging rail 131 is dragged to slide relative to the second hanging rail 132 by the connecting unit 120.

Referring to fig. 4, which illustrates a cabinet 200 as an example of furniture, the cabinet 200 includes a first sidewall 210 and a second sidewall 220, and a slide rail assembly 100 connecting the first sidewall 210 and the second sidewall 220. The first side wall 210 and the second side wall 220 are connected by the slide rail assembly 100, and thus the slide rail assembly 100 functions as a framework in the cabinet 200. Since the slide rail assembly 100 can be extended and contracted, the first and second sidewalls 210 and 220 can be moved closer to or farther away. The first side wall 210 and the second side wall 220 form a cabinet cavity of the cabinet 200 therebetween, and when the first side wall 210 and the second side wall 220 are close to each other, the cabinet cavity is reduced; as the first sidewall 210 and the second sidewall 220 move away, the cabinet cavity increases.

Specifically, the first sidewall 210 is connected to the first rod 111, and the second sidewall 220 is connected to the second rod 112. Since the telescopic rod unit 110 serves as a supporting body and functions as a skeleton in the entire slide rail assembly 100, the hanger rail unit 130 may not be directly connected to the first and second side walls 210 and 220. Of course, to enhance the structural strength of the entire cabinet 200, the first hanger rail 131 may be connected to the first sidewall 210, and the second hanger rail 132 may be connected to the second sidewall 220.

It should be noted that the slide rail assembly 100 of the above embodiment may further include a third rod (not shown), and the first rod 111, the second rod 112 and the third rod are slidably sleeved. The number of the third rod bodies can be selected according to actual needs. When the sliding rail assembly 100 includes a third rod, the connecting unit 120 further includes a third connecting member, and the hanger rail unit 130 further includes a third hanger rail, and the third hanger rail is connected to the third rod through the third connecting member. In addition, when the sliding rail assembly 100 includes the third rod, the third connecting member and the third hanging rail, the assembling relationship between the third rod, the third connecting member and the third hanging rail and other components can be changed adaptively according to the description of the embodiment of the present application, and will not be described in detail herein.

As shown in fig. 4, in addition to the function of the slide rail assembly 100 to support the first and second side walls 210 and 220, the slide rail assembly 100 also functions as a folding door 240 to which the cabinet 200 is attached. The folding door 240 includes a plurality of door leaves 241 connected in sequence, and each door leaf 241 is connected to the hanger rail unit 130. For example, each door leaf 241 is provided with a sliding member, which may be a sliding pin or a sliding wheel. As shown in fig. 1, each of the first and second hanger rails 131 and 132 is provided with a hanger groove 133, and the slider is suspended in the hanger groove 133 and can slide along the hanger groove 133. When the slide rail assembly 100 is extended to the fully unfolded state, the first hanging rail 131 and the second hanging rail 132 are straightly butted and extended in the same direction, so that the slider can slide from the hanging groove 133 of the first hanging rail 131 to the hanging groove 133 of the second hanging rail 132. Of course, further, when the first hanging rail 131 and the second hanging rail 132 extend in the same direction, the hanging groove 133 of the first hanging rail 131 and the hanging groove 133 of the second hanging rail 132 are butted, so that the sliding member can be smoothly transferred between the hanging groove 133 of the first hanging rail 131 and the hanging groove 133 of the second hanging rail 132, and the sliding member is not clamped at the position where the adjacent hanging grooves 133 are butted due to poor butting of the adjacent hanging grooves 133.

As shown in fig. 2, fig. 2 is a schematic structural view of the slide rail assembly 100 shown in fig. 1 in a shortened state. When the slide rail assembly 100 is in the shortened state, the first hanging rail 131 and the second hanging rail 132 are in a stacked state. In the embodiment shown in fig. 2, the second hanger rail 132 is stacked above the first hanger rail 131. Therefore, when the cabinet 200 needs to be changed from the unfolded state to the shortened state, the folding door 240 needs to be folded first, and the sliding members of the door leaf 241 need to be slid into the hanging grooves 133 of the first hanging rails 131.

As shown in fig. 2, when the slide rail assembly 100 is in the shortened state, the first hanger rail 131 and the second hanger rail 132 are in a stacked state, and the second hanger rail 132 is stacked above the first hanger rail 131. Since the first connecting member 121 connects the first hanger rail 131 and the first rod 111, and the second connecting member 122 connects the second hanger rail 132 and the second rod 112, at least the second connecting member 122 can be extended and contracted in the vertical direction. Fig. 3 is a schematic structural diagram of the connection unit 120 in an embodiment of the present application, and specifically, taking the second connection member 122 as an example, the second connection member 122 includes a first fixing portion 120A and a second fixing portion 120B, the first fixing portion 120A and the second fixing portion 120B are slidably disposed along an illustrated telescopic direction, and the illustrated telescopic direction is perpendicular to the telescopic direction of the telescopic rod unit 110. The first fixing portion 120A is U-shaped, and the first fixing portion 120A is connected to the second rod 112 of the telescopic rod unit 110. The second fixing portions 120B are two and are respectively connected to both ends of the U-shaped first fixing portion 120A, and further, the second fixing portion 120B is connected to the second hanger rail 132 of the hanger rail unit 130. In some embodiments, the first connecting element 121 can also extend and contract along a vertical direction, for example, the first connecting element 121 includes a first fixing portion 120A and a second fixing portion 120B, the first fixing portion 120A and the second fixing portion 120B are slidably disposed along the extending and contracting direction, the first fixing portion 120A is connected to the first rod 111 of the telescopic rod unit 110, and the second fixing portion 120B is connected to the first hanger rail 131 of the hanger rail unit 130.

It should be appreciated that as shown in fig. 2, the second hanger rail 132 is stacked above the first hanger rail 131, and the second hanger rail 132 moves above the first hanger rail 131 when the slide rail assembly 100 changes from the fully extended state to the shortened state. Therefore, the distance between the first hanging rail 131 and the first rod 111 may not be changed, and therefore the first connecting member 121 may not be configured to be a telescopic structure, and the first connecting member 121 may be configured to be a fixed base, one end of the fixed base is connected to the first hanging rail 131, and the other end of the fixed base is connected to the first rod 111.

With reference to fig. 3, when the first connecting element 121 and the second connecting element 122 are of a retractable structure, the first fixing portion 120A is provided with a guiding groove 120A1, the guiding groove 120A1 is provided with a plurality of limiting grooves 120A2, and the limiting grooves 120A2 may be semi-circular arc-shaped. The limiting grooves 120A2 are arranged along the sliding direction of the first fixing portion 120A and the second fixing portion 120B. The second fixing portion 120B is provided with a slide pin 120B1 slidably connected to the guide groove 120a1, and the slide pin 120B1 is fitted in a different stopper groove 120a2 when sliding along the guide groove 120a 1. It should be understood that when the slide pin 120B1 is engaged with one of the retaining grooves 120a2, the retaining groove 120a2 can serve to retain or position the slide pin 120B 1. When the slide pin 120B1 needs to be transferred between different stopper grooves 120A2, the first fixing portion 120A and the second fixing portion 120B may be pressed in the telescopic direction shown in fig. 3.

As shown in fig. 2, the slide rail assembly 100 may further include a pulley unit 140, and the pulley unit 140 connects the first and second hanger rails 131 and 132. When the slide rail assembly 100 is extended to the fully extended state, the first hanging rail 131 and the second hanging rail 132 extend in the same direction, and when the slide rail assembly 100 is changed from the fully extended state to the shortened state, the second hanging rail 132 moves above the first hanging rail 131. By providing the pulley unit 140, the moving process of the second hanging rail 132 with respect to the first hanging rail 131 can be made smoother.

Specifically, as shown in fig. 2, the pulley unit 140 may include a first pulley 141, a pulley bracket 143, and a second pulley 142. The first pulley 141 and the second pulley 142 are both connected to a pulley bracket 143. The first hanger rail 131 is provided with a first slide groove 131A, the second hanger rail 132 is provided with a second slide groove 132A, the first pulley 141 is slidably connected to the first slide groove 131A, and the second pulley 142 is slidably connected to the second slide groove 132A. The first chute 131A is used for guiding the sliding of the first pulley 141, and the second chute 132A is used for guiding the sliding of the second pulley 142; therefore, the pulley unit 140 connects the first hanger rail 131 and the second hanger rail 132, so that when the second hanger rail 132 slides relative to the first hanger rail 131, the first runner 131A and the second runner 132A guide the first hanger rail 131 and the second hanger rail 132 to prevent the first hanger rail 131 and the second hanger rail 132 from being misaligned.

In one embodiment, the first pulley 141 may be built in the first chute 131A, and the second pulley 142 may be built in the second chute 132A. The built-in means here is not to say that the first pulley 141 is provided entirely in the first chute 131A, and the second pulley 142 is provided entirely in the second chute 132A; the built-in means that the first pulley 141 cannot be disengaged from the first sliding groove 131A and the second pulley 142 cannot be disengaged from the second sliding groove 132A during the normal use of the slide rail assembly 100. Specifically, the first pulley 141 and the pulley bracket 143 may be rotatably connected by a connecting shaft, and the second pulley 142 and the pulley bracket 143 may be rotatably connected by another connecting shaft. Both ends of the connecting shaft, to which the first pulley 141 is connected with the pulley bracket 143, protrude to both sides, and both ends of the connecting shaft are slidably caught to both inner walls of the first slide groove 131A, so that the first pulley 141 can slide along the first slide groove 131A but cannot be separated from the first slide groove 131A. Similarly, both ends of the connecting shaft connecting the second pulley 142 and the pulley bracket 143 protrude to both sides, and both ends of the connecting shaft are caught to both inner walls of the second sliding groove 132A, so that the second pulley 142 can slide along the second sliding groove 132A but cannot be separated from the first sliding groove 131A. The above arrangement can ensure the stability of the connection of the pulley unit 140 with the first and second hanger rails 131 and 132.

As shown in fig. 1, the first and second hanger rails 131, 132 each include a first end 130A and a second end 130B. When the slide rail assembly 100 is extended to the fully extended state, the second end 130B of the first hanging rail 131 is abutted with the first end 130A of the second hanging rail 132. As shown in fig. 2, the first end 130A is provided with a first guide surface 130A1 and the second end 130B is provided with a second guide surface 130B 1. As shown in fig. 1, when the slide rail assembly 100 is extended to the fully extended state, a portion of the second guide surface 130B1 of the first hanging rail 131 is attached to a portion of the first guide surface 130a1 of the second hanging rail 132. As shown in fig. 2, when the slide rail assembly 100 is converted from the fully extended state to the shortened state, the first guide surface 130a1 of the second hanging rail 132 slides along the second guide surface 130B1 of the first hanging rail 131, so that the first hanging rail 131 and the second hanging rail 132 are stacked, and the second hanging rail 132 is located above the first hanging rail 131. When the first hanger rail 131 and the second hanger rail 132 slide with each other, i.e. the slide rail assembly 100 is converted from the fully unfolded state to the shortened state, or the slide rail assembly 100 is converted from the shortened state to the fully unfolded state, the first guide surface 130a1 and the second guide surface 130B1 abut against each other and cooperate to make the sliding process of the first hanger rail 131 and the second hanger rail 132 smooth.

With reference to fig. 2, the first guiding surface 130a1 includes a first outward curved surface 130a11 and a plane 130a12 connecting the first outward curved surface 130a11, and when the sliding rail assembly 100 is converted from the fully extended state to the shortened state, the first outward curved surface 130a11 slides along the second guiding surface 130B1, so that the first hanging rail 131 and the second hanging rail 132 are stacked. The second guiding surface 130B1 includes a concave arc surface 130B11 and a second convex arc surface 130B12 connected to the concave arc surface 130B11, and when the slide rail assembly 100 is changed from the fully expanded state to the shortened state, the first convex arc surface 130a11 slides along the concave arc surface 130B11 and the second convex arc surface 130B12 in sequence, so that the first hanging rail 131 and the second hanging rail 132 are in a stacked state.

The following description will proceed with reference to the cabinet 200 as an example. As shown in fig. 4, the furniture further includes a floor unit 230, the floor unit 230 includes a plurality of slidably coupled unit plates 231, and the unit plates 231 positioned at left and right ends of the floor unit 230 are coupled to the first and second sidewalls 210 and 220, respectively, when the floor unit 230 is unfolded. For example, when the second sidewall 220 is pushed to the left to make the second sidewall 220 close to the first sidewall 210, the unit plates 231 connected to the second sidewall 220 also start to move toward the unit plates 231 connected to the first sidewall 210, and the unit plates 231 of the floor unit 230 are stacked, so that the floor unit 230 composed of the unit plates 231 can be made to be telescopic.

As shown in FIG. 4, the cabinet 200 further includes a flexible film roll screen 250 disposed on the opposite side of the base plate unit 230. Wherein the base plate unit 230 is located at the bottom and the flexible film curtain 250 is located at the top when the cabinet 200 is normally placed. Referring to fig. 4 and 6, the flexible film roll screen 250 includes a roll shaft 251 and a screen body 252 wound around the roll shaft 251. The roller 251 may be rotatably connected to the first sidewall 210, and the free end of the roll screen body 252 is connected to the second sidewall 220, and the free end of the roll screen body 252 refers to the end of the roll screen body 252 not connected to the roller 251. When the first and second sidewalls 210 and 220 are moved away from each other, the second sidewall 220 pulls the free end of the roll screen body 252, so that the roll screen body 252 is gradually separated from the winding shaft 251. Further, the reel 251 has an automatic winding function. For example, a torsion spring may be installed between the winding shaft 251 and the first sidewall 210, and when the first sidewall 210 and the second sidewall 220 are close, the elastic force of the torsion spring may drive the winding shaft 251 to rotate around the rotation axis of the winding shaft 251, so that the roll screen body 252 is rewound on the winding shaft 251. Of course, in other embodiments, the roller 251 can also be rotatably mounted on the second side wall 220, and the free end of the roller blind body 252 is mounted on the first side wall 210. In some embodiments, the flexible film roller blind 250 is provided with an LED light source, so that the flexible film roller blind 250 can emit light to supplement light to the inner cavity of the cabinet 200.

As shown in fig. 5, fig. 5 is a perspective view of a furniture in an embodiment of the present application from above, and in conjunction with fig. 4 and 5, the furniture further includes a telescopic clothes rod 270. The telescopic clothes bar 270 includes a first bar portion 271 and a second bar portion 272 which are slidably coupled, the first bar portion 271 being coupled to the first sidewall 210, and the second bar portion 272 being coupled to the second sidewall 220. When the first and second sidewalls 210 and 220 approach or move away from each other, the telescopic laundry rod 270 can be extended and shortened accordingly.

Further, as shown in fig. 4, the furniture further includes a telescopic trousers hanger 260. The telescopic rack 260 includes a first folding telescopic support 261, a second folding telescopic support 262 and a plurality of support rods 263.
