Description

FIELD OF THE INVENTION

This application relates to mechanical systems for fixing and coupling and, in particular, to a bracket assembly and a storage rack system.

DESCRIPTION OF THE PRIOR ART

Storage racks are commonly used in our daily life usually for storage of clothes, daily necessities and the like in household applications and goods and products in commercial scenarios. Storage racks adapted to be mounted to a vertical surface are popular among and widely used by supermarkets and shopping malls because of less space occupied. Such a storage rack is often formed by mounting several brackets to a vertical wall or panel surface and then horizontally placing shelves on the brackets. In another common form of such storage racks, brackets are fastened to horizontal beams or upright columns fixedly mounted to a wall or panel surface, and shelves are in turn mounted to the brackets.

In both forms, shelves are secured to brackets that are fixed to upright or horizontal supports. Generally, the brackets are adapted to the shelves, i.e., the shelves require the brackets to be structured accordingly. For example, the shelves may be mesh shelves, and in this case, the structure of the brackets would be suitable for replacement of such shelves, but not of, for example, wood shelves, cabinets or drawers. In other words, each type of bracket in conventional storage rack systems can be suitably used with only a single type of shelf, and different types of shelves require the use of different types of brackets.

In addition, conventional brackets are usually triangular structures, and placement of certain shelves thereon requires passing associated fasteners through both the bracket and shelf. The triangular shape of such brackets means a varying distance between the top side, on which a bracket is to be placed, and the opposite bottom side across the length. Therefore, the use of fasteners of various lengths is required. This not only raises the manufacturing cost, but also leads to a tedious assembly process. Further, conventional brackets cannot be stably assembled with upright columns, and wobbling tends to occur during use.

Therefore, those skilled in the art are dedicated towards developing a bracket assembly, which has a wider scope of application and can be suitably used with different types of shelves, dispensing with the need for replacement or retrofit of brackets when a different type of shelf is to be used. Moreover, it allows fasteners of the same size to be used and can be used to assemble a storage rack with increased stability.

Compared with the prior art, the storage rack system of the present application has the benefits as follows:

• • 1. The differently structured mating portions enable the brackets to connect carrier components of different structures, making the bracket multi-functional and usable in a wider range of applications.
  • 2. Using such brackets in a storage rack system allows carrier components of different structures to be used in the storage rack system, such as mesh shelves, plate-like shelves, drawers and hanging hooks, in any combination. This enables the storage rack system to be used in a more flexible way and dispenses with the need for manufacturing brackets of various structures, resulting in reductions in manufacturing and assembly costs.
  • 3. Using such brackets in a storage rack system allows carrier components of different structures to be readily replaced, without requiring the replacement of brackets, resulting in higher assembly efficiency and lower replacement cost.
  • 4. The guide structure allows a carrier component to be secured to the bracket using fasteners of the same length at different locations of the bracket. This can facilitates user operation and reduce the manufacturing cost. Moreover, the guide structure can define a direction in which a fastener is inserted through the bracket and the carrier component, avoiding oblique or deviated deployment of the fastener, which is detrimental to reliably attachment of the carrier component to the bracket.
  • 5. The guide structure may be provided as a component separate from the bracket and can be extensively used on various brackets designed without considering the guide structure. This dispenses with the need for manufacturing new brackets for existing storage rack systems.
  • 6. The anti-dislodgement structure can prevent the bracket from dislodging from a slot in an upright column, enabling the bracket to be more stably coupled to the upright column and making the entire storage rack system more reliably and stable.
  • 7. A carrier component can be attached to the bracket by means of a guide rail so as to be pulled out or pushed back on the guide rail. When a user desires to pick up or place an item, he/she can pull the carrier component out relative to the guide rail to more easily pick up the item.

Below, the concept, structural details and resulting effects of the present application will be further described with reference to the accompanying drawings to provide a full understanding of the objects, features and effects of the application.

I. Bracket Assembly

As shown in FIGS. 1, 2 and 4, the present application provides a bracket assembly 10 including a bracket 100 which is provided in a storage rack system to support a carrier component in the storage rack system. One end of the bracket 100 defines a connecting portion 101, through which the bracket 100 can be coupled to an upright column 300 or horizontal beam 400 in the storage rack system. The bracket 100 also defines a mating portion which can be connected to the carrier component, thereby connecting the carrier component to the bracket 100 and allowing goods to be then stored on the carrier component.

The carrier component may be of various structures. For example, the carrier component may be a mesh shelf 210 in the form of a mesh consisting of multiple interwoven struts. Alternatively, the carrier component may be a plate-like shelf 230 in the form of a storage plate made of wood, plastic, metal, etc. Still alternatively, the carrier component may be a drawer-like structure, which may be mated with the bracket 100 through a guide rail, or connected to the bracket 100 using fasteners. Yet still alternatively, the carrier component may be a hanging hook 250. Depending on its structure, the carrier component may be connected to the bracket 100 in different ways. In the present application, the bracket 100 may define mating portions of at least two different structures, which can be connected to carrier components of different structures. In conventional storage rack systems, each bracket defines only one type of mating portion and therefore can be connected to only a defined single type of carrier component. When a different type of carrier component is to be used, replacement with another bracket with a corresponding type of mating portion is necessary. In contrast, according to the present application, as the bracket 100 can accommodate carrier components of at least two different structures, replacement between these differently-structured carrier components can be made simply without requiring replacement of the bracket 100. It will be understood that the bracket 100 may define mating portions of three or more types and can be thus used in a wider range of applications, without departing from the scope of the present application. For example, in the embodiment shown in FIGS. 1, 2 and 4, the bracket 100 defines a first mating portion 110, a second mating portion 120, a third mating portion 130 and a fourth mating portion 140. The first mating portion 110 can be connected to a first mating component 210, such as a carrier component in the form of a mesh shelf. The second mating portion 120 can be connected to a second mating component 230, such as a plate-like carrier component. The third mating portion 130 can be connected to a third mating component, which can be in turn connected to a drawer-like, cage-like or basket-like or other carrier component 240 defining a storage space. The fourth mating portion 140 can be connected to a fourth mating component 250, such as a hook-like carrier component. In the illustrated embodiment, any two, three or four of the first 110, second 120, third 130 and fourth 140 mating portions may be included. It will be understood that, in the shown embodiment, other mating portions may also be included in addition to those illustrated.

FIGS. 1 to 21 show a first embodiment. Referring to FIG. 1, the present application provides a bracket assembly 10 including a bracket 100. The bracket 100 is generally triangular and defines, on its shortest side (first side 102), a connecting portion 101 for connecting the bracket 100 to an upright column 300 or horizontal beam 400. The other two sides (a second side 103 and a third side 104) both extend from the first side 102 and form an acute angle therebetween. As viewed in the orientation of the figure, the second side 103 is an upper side, and the third side 104 is a lower side. It will be understood that the shape of the bracket 100 is not limited to being triangular, as described herein, and may be any other suitable shape, such as quadrilateral.

The bracket 100 includes a first bracket wall 105 and a second bracket wall 106, which are substantially parallel to each other. It also includes a bottom bracket wall 107 attached to the bottom of both the first bracket wall 105 and the second bracket wall 106. The first bracket wall 105 and the second bracket wall 106 are of the same substantially triangular shape. The first bracket wall 105 and the second bracket wall 106 are substantially of the same structure, and only one of them is exemplified below.

The connecting portion 101 of the bracket 100 includes a lug 1011 protruding from the first side 102 of the bracket 100. The lug 1011 can be inserted into a slot 301 in the upright column 300 or horizontal beam 400, thereby securely connecting the bracket 100 thereto. It will be understood that the connecting portion 101 may be alternatively provided in the form of, for example, a fastener structure which can connect the bracket 100 to the upright column 300 or horizontal beam 400.

As shown in FIGS. 3 and 4, the bracket 100 defines, on the second side 103 that is to be brought into direct contact with a carrier component, a first mating portion 110 for connecting a mesh shelf 310. Specifically, the first mating portion 110 includes a number of first notches 111, which are provided at the second side 103 in a row along its lengthwise direction. During use, transverse rod-like components 211 of the mesh shelf 210, which are perpendicular to the bracket 100, are passed through openings 112 of the first notches 111 and pushed down into the first notches 111 so that the mesh shelf 210 is prevented from sliding in the lengthwise direction of the bracket 100. In some implementations, the openings 111 of the first notches 111 has a dimension in the lengthwise direction of the bracket 100, which is smaller than a length of the first notches 111. The openings 112 are defined at one end of the first notches 111, and receptacles 113 are defined at the other end of the first notches 111. After the rod-like components of the mesh shelf 210 enter the openings 112, the mesh shelf 210 may be pushed so that the rod-like components are further urged into the receptacles 113 (see FIG. 5). Projections 114 above the receptacles 113 can block the mesh shelf 210 from dislodgement from the bracket 100, increasing the stability of the mesh shelf 210 on the bracket 100.

For a storage rack system employing such mesh shelves 210, the stability of the mesh shelves 210 on the brackets 100 is one of the main factors that influence the load capacity of the storage rack system. Referring to FIG. 3, the mesh shelf 210 is made up of multiple parallel transverse rod-like components 211 and multiple parallel longitudinal rod-like components 212. Specifically, the transverse rod-like components 211 may be arranged under the longitudinal rod-like components 212 so that they cross each other to form a mesh-like structure. The bracket 100 defines, at an edge thereof opposite to the connecting portion 101 (i.e., at a leading end of the bracket 100), a first stop notch 108. Also, the bracket 100 defines a second stop notch 109 around the connecting portion (i.e., at a trailing end of the bracket 100). Both the first stop notch 108 and the second stop notch 109 are curved, semi-closed structures. The first stop notch 108 is obliquely open upward toward the leading end, while the second stop notch 109 is obliquely open upward toward the trailing end. When a transverse rod-like component 211 of the mesh shelf 210 is received in the first stop notch 108 so as to be brought into contact with the bottom of the first stop notch 108, the first stop notch 108 can stop the mesh shelf 210 from moving toward the trailing end. The transverse rod-like components 211 can be received in the receptacles 113 of the first notches 111. In this configuration, one of the transverse rod-like components 211 of the mesh shelf 210 is received in the second stop notch 109. Stopped by the second stop notch 109, the mesh shelf 210 cannot move toward the leading end. In order to additionally stabilize the mesh shelf 210 on the bracket 100, a stop element 220 may be provided at the trailing end of the bracket 100 to secure the mesh shelf 210 (see FIGS. 3 and 6). As shown in FIG. 7, the stop element 220 includes two washers 221 and a curved stop tab 222. The two washers 221 are substantially parallel, and are joined by a trailing end 224 of the stop tab 222, to each other. As shown in FIGS. 6 and 7, the washers 221 are shaped similarly to the lug 1011. Equally-sized holes may be provided at aligned locations of the lug 1011 and the washers 221, and the washers 221 may be fixed to the lug 1011 by screws inserted in the holes. The fixation may be accomplished otherwise, for example, by welding or riveting. It will be understood that, in the latter case, it is unnecessary to provide the holes in the lug 1011 and washers 221. The stop element 220 is made of a metal or plastic material with a certain degree of elasticity. The stop tab 222 is curved, and a curved portion of it defines a receptacle 223. When the stop element 220 is fixedly connected to the bracket 100, the receptacle 223 of the curved stop tab 222 can receive a transverse rod-like component 211, as shown in FIG. 8. Specifically, an external force may be applied to deflect the stop tab 222 to increase a radius of curvature of the curved contour of the stop tab 222 to expand the receptacle 223 that it defines to allow the transverse rod-like component 211 to be received therein. After the force is removed, the stop tab 222 restores its original shape due to its elasticity. That is, the radius of curvature of the curved contour of the stop tab 222 decreases. Accordingly, the receptacle 223 defined by the curved contour shrinks, stopping the transverse rod-like component 211 within the stop tab 222.

As shown in FIGS. 2, 9 and 10, a second mating portion 120 is used to connect a plate-like shelf 230. The plate-like shelf 230 is an integral, continuous, flat plate and may be generally made of wood, plastic, metal, or the like. If the plate-like shelf 230 is directly placed on the bracket 100, it tends to slide on the bracket 100 in its lengthwise direction and cannot reside stably thereon. The second mating portion 120 can be used to fix the plate-like shelf 230 to the bracket 100, increasing its stability on the bracket 100. The second mating portion 120 includes at least one through hole 121 vertically extending through the bottom bracket wall and a fastener 122 which can be inserted in the through hole. For example, the fastener 122 may be a long nail, which can be inserted into the through hole 121 from the bottom of the bracket upwards. After a pointed tip of the long nail is passed through the through hole, the nail may be hammered to drive the tip into the plate-like shelf 230. Alternatively, the fastener 122 may be a screw, which may be passed through the through hole 121 and screwed into the plate-like shelf 230.

As shown in FIGS. 1, 1112 and 13, a third mating portion 130 is used to connect a carrier component 240 defining a storage space, such as a drawer-like carrier component shown in the illustrated example. As shown in FIGS. 1 and 4, the third mating portion 130 includes at least one second notch 131 in the bracket 100, which can mate with a third mating component implemented as a first clasp 132. In use, the first clasp 132 is snap-engaged in the second notch 131, and a fastener is then used to connect the first clasp 132 to a side panel 241 of the carrier component 240, thereby securing the carrier component 240. The second notch 131 is recessed from the first side 102 of the bracket 100. As shown in FIGS. 14 and 15, the first clasp 132 includes a first side wall 1321 and a second side wall 1322, which oppose each other. Top ends of the first side wall 1321 and the second side wall 1322 are joined to each other by a top wall 1323. The first side wall 1321 and the second side wall 1322 define a gap 1324 therebetween, which allows the clasp to be snap-engaged in the second notch 131 of the bracket 100. The fastener is passed through a through hole 1325 extending through the second side wall 1322 in its thickness direction and is then connected to the side panel 241 of the carrier component 240. In some implementations, as shown in FIG. 14, the first clasp 132 further includes an elastic portion 1326 provided on a surface of the second side wall 1322 facing the first side wall 1321. As shown in FIG. 16, when the first clasp 132 is received in the second notch 131, the elastic portion 1326 abuts against a wall around the second notch 131, thereby securely snap-engaging the first clasp 132 in the second notch 131. It will be understood that the carrier component 240 may be implemented as a drawer (see FIG. 11), cage-like carrier component, basket-like carrier component or other carrier component that defines an internal storage space. All these carrier components 240 have a storage space in which goods can be stored. That is, they all have an internal volume for storage of goods.

In another implementation, the at least one second notch 131 may be structured as shown in FIG. 17. Opposite end portions of an opening of the second notch 131 extend toward the interior of the second notch 131, thus defining a first extension 1311 and a second extension 1312. A surface of the first extension 1311 facing the bottom of the second notch 131 is configured as a slanted surface 1313. With this configuration, as shown in FIG. 18, the first clasp 132 must be held obliquely at an angle before it can be inserted into the second notch 131. The angle the first clasp 132 must be held obliquely may be substantially equal to an angle the surface 1313 is slanted. Once received in the second notch 131, the first clasp 132 will be blocked by the first extension 1311 and the second extension 1312 from dislodgement from the second notch 131, thereby stabilizing the carrier component. That is to say, blocked by the first extension 1311 and the second extension 1312, the carrier component 240 must be deployed or removed obliquely, rather than perpendicularly to the lengthwise direction of the bracket. Preferably, the second notch 131 is arranged around the connecting portion 101 and structured as shown.

In another implementation, the first clasp 132 is structured as shown in FIG. 19. In the example of FIG. 19, the first clasp 132 includes only a first side wall 1321 and a second side wall 1322. Top ends of the first side wall 1321 and the second side wall 1322 are joined to each other by a top wall 1323. The first side wall 1321 and the second side wall 1322 define a gap 1324 therebetween, in which a side wall of the bracket that defines the second notch 131 can be received. The first side wall 1321 is elastic and can be biased toward the second side wall 1322. Once snap-engaged in the second notch 131, the first side wall 1321 is biased toward the second side wall 1322 and thereby firmly engaged with the side wall of the bracket that defines the second notch 131. Preferably, a locking hole 1327 is provided on the first side wall, and a locking stud 1314 which can mate with the locking hole 1327 is provided on the side wall of the bracket that defines the second notch 131 (see FIG. 16). The locking stud 1314 is spherical, projects toward the side wall of the bracket and can snap into the locking hole 1327.

As shown in FIGS. 2 and 20, a fourth mating portion 140 is used to connect a hanging hook 250. As shown in FIGS. 21 and 22, the fourth mating portion 140 includes two through slots 141 provided at the bottom of the bracket in correspondence with two respective snap tongues on the hanging hook 250, namely, a first snap tongue 252 and a second snap tongue 253. The first snap tongue 252 of the hanging hook 250 has a projection 254 projecting in a leading direction of the bracket 100. After the first snap tongue 252 and the second snap tongue 253 of the hanging hook are passed through the respective through slots 141, the hanging hook 250 can be moved in the leading direction of the bracket 100 to bring the projections 254 into abutment with the bottom of the bracket 100, thereby securely hanging the hanging hook 250 on the bracket 100. It will be understood that the fourth mating portion 140 may also be provided as a threaded hole, and a fastener such as a screw may be used to fix the hanging hook 250 to the bracket 100. The hanging hook 250 includes a hook portion 255. Two hanging hooks 250 may be provided in parallel and opposition to each other, and a hang bar 251 may be horizontally placed on both the hook portions 255 of the hanging hooks 250

In some implementations, as shown in FIGS. 23 and 24, a cover component 260 may be provided on the bracket 100, which covers the entire mesh shelf 210 to not only provide protection but also allow goods to be stored thereon.

When the bracket 100 of the first embodiment is used in a storage rack system, carrier components of different structures may be arranged thereon, as required. As shown, examples of the carrier components may include mesh shelves 210, plate-like shelves 230, hanging hooks 250 and other carrier components 250 defining a storage space. Alternatively, carrier component of the same single structure may be arranged on the bracket 100. In the case, the carrier component may be replaced with carrier component of a different structure, as required, without requiring replacement of the bracket.

The bracket 100 of the first embodiment includes two side walls 103, which may be formed by bending a single sheet of material.

Example 2

As shown in FIG. 25, a bracket according to a second embodiment differs from that of the first embodiment in consisting of a single sheet 1001. The single sheet may be of the same structure as the first bracket wall 105 or the second bracket wall 106 in the bracket of the first embodiment. The sheet 1001 may define, at its second side 103, a notch 150 for mating with a carrier component. Around the second side 103, there is provided a through hole 155, through which a fastener may be passed and connected to the carrier component. A through hole (not shown) is provided in the sheet 1001, which extends from the second side 103 to a third side 104, and a fastener may be passed through the through hole and connected to a plate-like shelf 230. The notch 150 can mate with a first clasp 132 for connecting a drawer 240.

In one implementation, as shown in FIGS. 26, 27 and 28, the bracket 100 of the second embodiment is provided with a second clasp 151, which can mate with the notch 150 by snap engagement therein. The second clasp 151 defines a recess 156 for receiving a transverse rod-like component 211 of a mesh shelf 210, and the mesh shelf 210 is covered with a plate-like component 152.

It will be understood that the bracket of the second embodiment can also define the first, second, third and fourth mating portions of the first embodiment. The connecting portion 101 and the stop element 220 of the first embodiment are also applicable to the second embodiment. The brackets of the two embodiments can be connected to a horizontal beam or upright column in the same way. The second clasp 151 of the second embodiment can also be used in the first embodiment to connect a carrier component.

Example 3

As noted above, the bracket 100 of the first embodiment may include a second mating portion 120, and a carrier component 20 may be secured to the bracket 100 by inserting a fastener (e.g., a screw) through the second mating portion 120 so that its one end passes through the bracket 100 from the third side 104 and then through the carrier component 20 (e.g., a plate-like shelf 230). However, it is to be noted that the bracket 100 of the first embodiment defines, across its length, a varying between the second side 103, with which the carrier component 20 is to be brought into direct contact, and the opposite third side 104, as shown in FIG. 29. A fastener 30 may be passed through the bracket 100 so that its one end protrudes out of the second side 103 while the other end remains exposed on the third side 104. For example, consider locations M and N in the figure. The bracket 100 has a greater width at location M than at location N. Therefore, it is obvious that the two locations require the use of fasteners 30 of different lengths and that a fastener 30a deployed at location M must be longer than a fastener 30b deployed at location N. Accordingly, a single storage rack system would require the use of fasteners 30 of various sizes. This will increase the cost of manufacturing the storage rack system because it is necessary to produce or purchase fasteners 30 of multiple different sizes, during the manufacturing. Moreover, more effort is required in assembly because the fasteners 30 of different sizes must be deployed at respective specific locations on the bracket 100. Further, during assembly, it is possible for one or more fasteners 30 to be deployed obliquely in the bracket 100 and the carrier component 20. Consequently, carrier component 20 may not be stably coupled to the bracket 100.

In order to overcome the above problem, a third embodiment provides a bracket assembly 10, which allows a carrier component 20 to be secured to a bracket 100 thereof using fasteners 30 of the same size without oblique deployment of any fastener 30 during assembly. It will be understood that the bracket 100 of this embodiment is limited to having a triangular shape and may have any other suitable shape. The present application is not limited to any particular shape of the bracket.

Referring to FIG. 30, the bracket 100 is generally triangular and defines, on its shortest side (first side 102), a connecting portion 101 for connecting the bracket 100 to an upright column 300 or horizontal beam 400. The other two sides (a second side 103 and a third side 104) both extend from the first side 102 and form an acute angle therebetween. As viewed in the orientation of the figure, the second side 103 is an upper side, and the third side 104 is a lower side.

The bracket 100 may be in the shape of a right triangle, in which the first side 102 and the second side 103 cross each other at a right angle. This triangular shape promises higher stability, which can additionally ensure stable coupling of the upright column 300, the bracket assembly 10 and the carrier component 20. The bracket 100 includes a first bracket wall 105 and a second bracket wall 106, which are substantially parallel to each other and both of the same shape as the bracket 100. A space between the first bracket wall 105 and the second bracket wall 106 defines a mounting cavity 1001. It will be understood that, in other implementations, the bracket 100 may also have any other regular or irregular shape, such as rectangular. In addition, the mounting cavity 1001 may also be formed in the bracket 100 by material removal. This embodiment is not particularly limited in this regard, as long as it can be ensured that the bracket assembly 10 has desirable stability and reliability.

Referring to FIGS. 31 to 33, in the bracket assembly 10 of this embodiment, the bracket 100 further includes a guide structure 310 disposed within the mounting cavity 103. A fastener 30 can pass through the guide structure 310 in the mounting cavity 1001 to couple a carrier component 20 to the bracket 100 in such a manner that its end away from the carrier component 20 can extend through both the mounting cavity 1001 and the guide structure 310 while the other end does not necessary remain exposed on the third side 104 of the bracket 100. In this way, fasteners 30 of the same length dimension can be used at various locations on the bracket 100, facilitating user operation. Preferably, the guide structure 310 defines a through hole 311 adapted for passage of the fastener 30 therethrough. The through hole 311 has a radial dimension, which is smaller than a dimension of the end of the fastener 30 away from the carrier component 20 and is greater than or equal to a dimension of the end of the fastener 30 oriented toward the carrier component 20. A distance between the through hole 311 and the second side 103 of the bracket 100 may be adapted to the size of a fastener 30 to be used so that the fastener 30 to be deployed in the through hole 311 may be of the same size as another fastener 30 deployed at a different locations on the bracket. The fastener 30 may be passed through the through hole 311 so that its end away from the carrier component 20 is blocked by an edge of the through hole 311 while the other end oriented toward the carrier component 20 is successively inserted through the through hole 311 and the second side 103 of the bracket 100 possibly into the carrier component 20. Specifically, as shown, without the guide structure 310 in the bracket 100, a fastener 30 would have been deployed so that its one end passes through the second side 103 of the bracket 100 while the other end remains on the third side 104 of the bracket 100. In the shown example, the bracket 100 has a greater width at location M than at location N, requiring the use of fasteners 30 of different lengths. In this case, the guide structure 310 may be deployed at location M, and a fastener 30 may be inserted into the bracket 100 so that its end away from the carrier component 20 is received within the through hole 311 of the guide structure 310 but not exposed outside of the bracket 100. At the same time, the distance between the through hole 311 of the guide structure 310 and the second side 103 of the bracket 100 can be adapted to the size of the fastener 30, another fastener 30 of the same size as that deployed at location M can be deployed at location N.

In some implementations, as shown in FIGS. 34 to 36, the guide structure 310 includes a guide channel 312 extending in the same direction as a first predetermined direction (labeled as +J in the figure) in which a fastener 30 is intended to be deployed. The guide channel 312 may be located below or above the through hole 311 (i.e., the guide channel 312 is arranged in line with the through hole 311 in the direction in which the fastener 30 is to be deployed). Opposite ends of the guide channel 312 define openings 3121, 3122. The fastener 30 may be inserted into the guide channel 312 from the opening 3122, through the guide channel 312 and out of the guide channel 312 from the other opening 3121. After that, it is further inserted through the through hole 311 in the guide structure 310. The guide channel 312 can ensure that the fastener 30 will not be deployed obliquely. In the guide structure 310, the guide channel 312 may be spaced apart from the through hole 311. That is, as shown in FIG. 36, there may be a gap 313 between the guide channel 312 and the through hole 311. It will be understood that the guide channel 312 may be directly formed integrally with the through hole 311. That is, the through hole 311 is located at the opening of the guide channel 312 closer to the carrier component 20 so to be open into the through hole 311 (i.e., the through hole 311 can be considered as part of the guide channel 312). It will be also understood that, although there is no other component between the through hole 311 and the second side 103 of the bracket 100 in the shown example, it is also possible to arrange the guide channel 312 or a similar component between the through hole 311 and the second side of the bracket.

In some implementations, the guide structure 310 is formed integrally with the bracket 100. That is, the guide structure 310 forms an inseparable part of the bracket 100. For example, the through hole 311 and/or the guide channel 312, through which a fastener 30 can be passed, may be provided in an projection disposed within the mounting cavity 1001 of the bracket 100. Alternatively, the guide structure 310 may be defined by a bent inner wall extension of the bracket 100.

In some implementations, as shown in FIGS. 37 and 38, the guide structure 310 may be a component separate from the bracket 100. Specifically, the guide structure 310 may be made up of a guide member 314 including a connecting portion 3141 and a guide portion 3142, which are joined to each other. The connecting portion 3141 is coupled to the bracket, and may define the through hole 311. The guide portion 3142 extends from the connecting portion 3141 in the first predetermined direction ±J and may define the guide channel 312. It will be understood that a gap 313 may be formed between the guide portion 3142 and the through hole 311 to separate the guide channel 312 from the through hole 311. Alternatively, there may be no gap between the guide portion 3142 and the through hole 311. That is, the through hole 311 may be located exactly at the adjacent end of the guide portion 3142. In this case, the through hole 311 provides one opening of the guide channel 312 of the guide portion 3142. Providing the guide structure 310 as a component separate from the bracket 100 allows the guide structure 310 to be used on legacy brackets not provided or formed with such guide structures 310. This can retrofit the legacy brackets at low cost and expand the scope of application of the guide structure 310.

In order to enable the carrier component 20 to be secured to the bracket using a fastener 30, a hole allowing the fastener 30 to be inserted therethrough is generally formed in the carrier component 20 beforehand. In order to assemble the carrier component 20, the hole in the carrier component 20 is first aligned with a corresponding hole in the second side of the bracket, and the fastener 30 is then successively passed through the hole in the bracket and that in the carrier component 20. In order to allow the carrier component 20 to be readily positioned on the bracket at a correct location where the hole in the carrier component 20 is aligned with that in the bracket, as shown, in this embodiment, the bracket also has a locating portion 315 which extends out of the mounting cavity 1001 of the bracket and can come into contact with the carrier component 20. In order to assemble the carrier component 20 with the bracket, a side wall of the carrier component 20 may be first brought into abutment against the locating portion 315 to place the carrier component 20 at a correct location where the assembly hole in the carrier component 20 is aligned with the through hole 311 of the guide structure 310 on the bracket. This avoids repeated alignment attempts possibly made during assembly, thus facilitating the assembly process. In some implementations, the locating portion 315 may be integrally formed with the bracket. In some implementations, as shown, the locating portion 315 may be provided by the guide member 314. Specifically, the locating portion 315 may be joined to the connecting portion 3141, preferably in the vicinity of an end thereof proximate the upright column, so as to extend out of the mounting cavity 1001 of the bracket.

According to this embodiment, instead of a single guide structure 310 as shown, a plurality of guide structures 310 may be provided on the bracket 100, if required. In addition, it is to be noted that, according to the present embodiment, the carrier component 20 is not limited to being implemented as a plate-like shelf as shown. The carrier component 20 may be in any other suitable form to be coupled with a fastener 30, without departing from the scope of the present embodiment.

The guide structure 310 in the bracket assembly of this embodiment allows fasteners 30 of the same size to be used at various locations on the bracket, without needing to consider the influence of factors including the shape and dimensions of the bracket. This results in reductions in manufacturing cost and facilitates assembly by a user.

Example 4

As noted above, the first side 102 of the bracket 100 shown in FIG. 1 is configured to allow the bracket to be coupled to an upright column 300 or horizontal beam 400. This may be accomplished by inserting a lug 1011 projecting from the first side 102 into a slot 301 in the upright column 300 or horizontal beam 400. Preferably, as shown, a pair of lugs 1011 is provided on the first side 102, each including an insertion section and an engagement section. In order to assemble the bracket 100 with an upright column 300, the lugs 1011 may be inserted into slots 301 in the upright column 300 and then lowered a small distance by an external force or the bracket's gravity so that the engagement sections engage a wall portion around the slots 301. In order to detach the bracket 100, the bracket 100 may be raised a small distance to disengage the engagement sections from the wall portion around the slots 301, and the lugs 1011 may be then pulled out of the slots 301. In other implementations, the lugs 1011 may also be engaged with the slots 301 by plug-in, threaded or other connections.

In order to more stably couple the bracket 100 to an upright column 300 or horizontal beam 400, as shown in FIGS. 39, 40, 41 and 43, a fourth embodiment provides a bracket assembly 10 further including an anti-dislodgement structure 410 capable of preventing the lugs 1011 of the bracket 100 from dislodging from slots 301 in the upright column 300 or horizontal beam 400, thereby stabilizing the bracket 100. The anti-dislodgement structure 410 includes a stop element 411 disposed within the mounting cavity 1001 so as to be slidable in a second predetermined direction (+K). The stop element 411 can extend toward the upright column 300 or horizontal beam 400 in the lengthwise direction of the bracket 100 out of the first side 102 of the bracket 100 so that its end located outside engages with a slot 301 in the upright column 300 or horizontal beam 400, thereby restricting the lugs 1011 from dislodgement from the slots 301. After the lugs 1011 engage the slots 301, the stop element 411 may be caused to slide so that its said end is inserted into the slot 301. By doing so, the bracket 100 cannot move relative to the upright column 300 in its lengthwise direction, preventing inadvertent dislodgement of the lugs 1011 from the slots 301, which may cause fall off of the bracket 100. In this way, the bracket 100 can be more reliably coupled to the upright column 300 without relative wobbling, stabilizing both the bracket 100 and the carrier component 20. In order to detach the bracket 100 from the upright column 300, the stop element 411 may be caused to slide away from the slot 301 in the opposite direction, followed by disengaging the lugs 1011 from the slots 301. The second predetermined direction may be exactly the shown ±K direction, or inclined at a small angle with respect to the +Y direction, as long as the stop element 411 is allowed to slide in the second predetermined direction into or away from the slot 301 in the upright column or horizontal beam.

In this embodiment, referring to FIGS. 42 and 43, the first wall and/or the second wall of the bracket 100 define(s) first slide slot(s) 412 extending in the second predetermined direction (or in a direction inclined at a small angle with respect to the second predetermined direction). The stop element 411 includes a stop portion 413 and a slide portion 414, which are joined to each other. The slide portion 414 is disposed so as to be able to slide within the first slide slot(s) 412 to cause the stop portion 413 to extend out of the bracket 100, or retract it back into the mounting cavity 1001 of the bracket 100. Preferably, the slide portion 414 is generally elongate in shape, and the stop portion 413 is joined to an end of the slide portion 414. The stop portion 413 may be integrally formed with the slide portion 414. The first slide slot(s) 412 may define a direction in which the slide portion 414 is slidable, thereby ensuring that the stop portion 413 slides always in this predefined direction. The slide portion 414 can slide in the −K direction within the first slide slot(s) 412 to extend out of the mounting cavity 1001 into the slot 301 in the upright column or horizontal beam. The slide portion 414 can also slide in the +K direction within the first slide slot(s) 412 away from the slot 301 back into the mounting cavity 1001. In some implementations, as shown in FIG. 44, a first avoidance slot 416 is provided in the bottom wall 107 of the bracket 100, and the stop element 411 further has a manipulation portion 415 which is joined to the slide portion 414 and at least partially protrudes out of the bracket 100 through the first avoidance slot 416. A user can push or pull the manipulation portion 415 to cause the slide portion 414 to slide within the slide slot(s) without needing to insert his/her finger into the mounting cavity 1001 or use any tool. Therefore, the user's operation can be facilitated.

Example 5

Similar to the fourth embodiment, a fifth embodiment of this application also includes a stop element which can be driven by an external force to move out of or back into the bracket so that a stop portion of the stop element is inserted into or pulled out of a slot in the upright column or horizontal beam. The two embodiments differ in how the stop element is actuated to slide. FIGS. 45 to 56 show the structure of the fifth embodiment.

According to the fifth embodiment, as shown in FIGS. 45 to 49, an anti-dislodgement structure 410 includes a support member 510 disposed on the first bracket wall 105 and/or the second bracket wall 106 of the bracket 100. The support member 510 defines a second slide slot 511 extending in the second predetermined direction. The anti-dislodgement structure 410 further includes a stop element 512 disposed so as to be able to slide in the second slide slot 511. The support member 510 serves to support the stop element 512, and the second slide slot 511 defines a direction in which the stop element 512 is slidable, thereby ensuring that the stop element 512 slides always in the second predetermined direction. The stop element 512 includes a stop portion 513 and a slide portion 514, which are joined to each other. The slide portion 514 is generally cylindrical in shape and defines a first thread 5141. The stop portion 513 is disposed at one end of the slide portion 514 and can extend out of the first side 102 from the mounting cavity 1001 of the bracket 100 into a slot 301 in an upright column or horizontal beam. The anti-dislodgement structure 410 further includes a manipulation portion 515 which is annular in shape and disposed over the stop portion 513. The manipulation portion 515 defines on its inner circumferential surface a second thread 5151 in engagement with the first thread 5141. Due to the engagement of the threads, rotating the manipulation portion 515 can cause the stop portion 513 to slide within the second slide slot 511 out of or back into the bracket 100. The threaded engagement of the manipulation portion 515 and the stop element 512 can prevent inadvertent sliding of the stop element 512 in the +K direction under the action of an external force, which may cause inadvertent dislodgement of the stop element 512 from the slot 301 in the upright column. Therefore, the stop element 512 can be coupled to the upright column 300 with higher reliability. The manipulation portion 515 can be rotated to actuate the slide portion 514 to slide in the −K direction, causing the stop portion 513 to move out of the mounting cavity 1001 into the slot 301. The manipulation portion 515 can also be rotated in the opposite direction to drive the slide portion 514 to slide in the +K direction slide, causing the stop portion 513 to move out of the slot 301 back into the mounting cavity 1001. As shown in FIG. 48, the first bracket wall 105 and/or the second bracket wall 106 of the bracket 100 define(s) second avoidance slot(s) 516. Preferably, two second avoidance slots 516 are defined in alignment with each other respectively in the first bracket wall 105 and the second bracket wall 106. The support member 510 includes a first support portion 517 and a second support portion 518. The first support portion 517 is disposed at one of the second avoidance slots 516, and the second support portion 518 is disposed at the other second avoidance slot 516. The first support portion 517 and the second support portion 518 are disposed in opposition, and connected, to each other to form the support member 510 so that the support member 510 defines an internal receptacle 524 (see FIG. 50) in which the manipulation portion 515 and the stop element 512 are at least partially received. In addition, the first support portion 517 and the second support portion 518 respectively define third avoidance slots 519, in which an outer circumferential surface of the annular manipulation portion 515 is at least partially exposed to allow a user to rotate the manipulation portion 515. Preferably, the manipulation portion 515 defines an anti-slip structure 535 on the outer circumferential surface, which may be composed of, for example, an uneven texture, bumps, ribs, grooves or the like formed in or on the outer circumferential surface. The anti-slip structure 535 allows a user to rotate the manipulation portion 515 with increased friction, which avoids difficult rotation of the manipulation portion 515 by the user due to slippage of his/or finger(s) on the manipulation portion 515. It will be understood that the anti-slip structure 535 may be any structure known in the art which can increase friction between the user's finger(s) and the outer circumferential surface of the manipulation portion 515. The present embodiment is not particularly limited in this regard.

Referring to FIGS. 51 to 56, the first support portion 517 includes a first cap portion 520 and at least one first protrusion 521 projecting from a side surface of the first cap portion 520. The first cap portion 520 is disposed at the second avoidance slot 516 in the first bracket wall 105, and the first protrusion 521 extends from the first cap portion 520 toward an opposite surface of the mounting cavity 1001. Preferably, two first protrusions 521 are included, which extend in parallel to each other. Similarly, the second support portion 518 includes a second cap portion 522 and at least one second protrusion 523 projecting from a side surface of the second cap portion 522. The second cap portion 522 is disposed at the second avoidance slot 516 in the second bracket wall 106, and the second protrusion 523 extends from the second cap portion 522 toward an opposite surface of the mounting cavity 1001. Preferably, two second protrusions 523 are included, which extend in parallel to each other. The first cap portion 520 and the second cap portion 522 can be mounted in the first bracket wall 105 and the second bracket wall 106, respectively, so that the first protrusions 521 come into contact with the second protrusions 523 and together delimit the receptacle 524 of the support member 510. The third avoidance slots 519 are respectively defined by the first cap portion 520 and the second cap portion 522 so as to both communicate with the receptacle 524. The manipulation portion 515 is received in the receptacle 524 so that its outer circumferential surface is at least partially exposed in the third avoidance slots 519 and accessible by a user from the outside of the bracket 100. Locating posts 525 are provided on end faces of the first protrusions 521 facing the second protrusions 523, and locating holes 526 are provided in end faces of the second protrusions 523 facing the first protrusions 521. The locating posts 525 can inserted into the locating holes 526, thereby connecting the first protrusions 521 and the second protrusions 523 together. The second slide slot 511 is defined by the first protrusions 521 and the second protrusions 523. Specifically, third notches 527 are provided in the end faces of the first protrusions 521 facing the second protrusions 523, and fourth notches 528 are provided in the end faces of the second protrusions 523 facing the first protrusions 521. When the protrusions are connected together, the third notches 527 and the fourth notches 528 make up the second slide slot 511. The slide portion 514 is passed through the second slide slot 511 so as to be confined and slidable therein. Inner walls of the third notches 527 and the fourth notches 528 respectively have first cut surfaces 530, and the slide portion 514 have a second cut surface 531 opposing the first cut surfaces 530. The second cut surfaces 531 extend in a lengthwise direction of the slide portion 514 and are not threaded. That is, the second cut surface 531 is a smooth surface. The second cut surface 531 contacts the first cut surfaces 530, with a slidable fit being formed therebetween. The slidable fit between the first cut surfaces 530 and the second cut surface 531 can prevent the stop element 512 from rotating in synchronization with the manipulation portion 515, ensuring that the stop element 512 can only slide in the second predetermined direction with respect to the bracket as a result of rotation of the manipulation portion 515. Preferably, the inner walls of the third notches 527 and the fourth notches 528 also respectively have third cut surfaces 532 opposing the first cut surfaces 530, and the slide portion 514 also has a fourth cut surface 533 opposing the second cut surface 531. A slidable fit is formed between the fourth cut surface 533 and the third cut surfaces 532.

Although the support member 510 has been described above as a component separate from the bracket 100, it will be understood that the support member 510 may alternatively be integrally formed with the bracket 100. That is, the support member 510 may form an inseparable part of the bracket 100.

In some implementations, as shown in FIGS. 45 and 48, the anti-dislodgement structure 410 further includes cover(s) 534 disposed over the second avoidance slot(s) 516 in the first bracket wall 105 and/or the second bracket wall 106 of the bracket 100. When it is not necessary to rotate the manipulation portion 515, the cover(s) 534 may be disposed over the second avoidance slot(s) 516 to conceal the manipulation portion 515, avoiding inadvertent dislodgement of the stop element 512 from the slot 301 caused by a user's inadvertent touch of the manipulation portion 515. This can also provide protection to the manipulation portion 515, the stop element 512 and other internal structures.

Example 6

In a sixth embodiment of the present application, there is provided a length-adjustable bracket assembly 10. As shown in FIGS. 57 to 61, the bracket assembly 10 includes a bracket 100 and an adjustment member 540 disposed at an end of the bracket 100 away from an upright column. The adjustment member 540 is movable relative to the bracket 100 into or out of its mounting cavity 1001, thus varying its length. The bracket 100 has a longer length when the adjustment member 540 extends out of the mounting cavity 1001. The bracket 100 has a shorter length when the adjustment member 540 is received within the mounting cavity 1001.

In some implementations, as shown in FIGS. 57 to 59, the adjustment member 540 is pivotally attached to the bracket 100. Specifically, the adjustment member 540 has a first end 541 and a second end 542, which oppose each other. At locations close to the first end 541, pivot holes 543 are provided, through which a pivot shaft 544 can be passed. The pivot shaft 544 can be successively inserted through the pivot holes 543 in the adjustment member 540 and corresponding holes in the bracket so that the adjustment member 540 can pivot about the pivot shaft 544. The adjustment member 540 can be pivoted so that its second end 542 can move into or out of the mounting cavity 1001 of the bracket 100. In order to restrict adjustment member 540 at defined positions, locating holes are provided in the adjustment member 540, and locating protrusions 548 capable of engaging with the locating holes are provided at corresponding locations on the bracket 100. The locating holes include a first locating hole 546 and a second locating hole 547, which are located on opposite sides of the pivot holes 543 in the lengthwise direction of the bracket. Engagement of the first locating holes 546 with the locating protrusions 548 means pivot of the adjustment member 540 in place into the mounting cavity 1001. Engagement of the second locating holes 547 with the locating protrusions 548 means pivot of the adjustment member 540 in place away from the bracket. The engagement of the locating holes with the locating protrusions 548 can retain the adjustment member at the defined positions.

In some implementations, as shown in FIGS. 60 to 61, the adjustment member 540 may also be slidably coupled to the bracket 100. Specifically, the adjustment member 540 has a first end 541 and a second end 542, which oppose each other. Sliders 549 are provided at locations close to the second end 542, and the bracket 100 defines, at corresponding locations, slide slots 550 extending in its lengthwise direction. The sliders 549 can slide within the slide slots 550. The adjustment member 540 can be actuated to move within the slide slots 550 so that its second end 542 moves into or out of the mounting cavity 1001 of the bracket 100. A length of the slide slot 550 defines a distance the adjustment member 540 can slide. Each slide slot 550 defines in its lengthwise direction a first end portion 551 and a second end portion 552. The first end portions 551 and the second end portions 552 can block further sliding of the sliders 549. The adjustment member 540 defines locating holes 553, and the bracket defines first locating protrusions 554 and second locating protrusions 555, which can engage with the locating holes. Engagement of the locating holes 553 with the locating protrusions means not only movement of the sliders 549 in place but also retention of the adjustment member 540 at the defined positions. Arrival of the sliders 549 at the first end portions 551 of the slide slots 550 means sliding of the adjustment member 540 in place into the mounting cavity 1001 and is accompanied by engagement of the locating holes 553 with the first locating protrusions 554, which retains the adjustment member 540 at the current position. Arrival of the sliders 549 at the second end portions 552 of the slide slots 550 means outward sliding of the adjustment member 540 in place away from the bracket 100 and is accompanied by engagement of the locating holes 553 with the second locating protrusions 555, which retains the adjustment member 540 at the current position.

It will be understood that the adjustment member is not limited to being retained at the aforementioned positions by engagement of the locating holes with the locating protrusions according to any of the above implementations, and any other suitable configuration capable of locating and retaining the adjustment member can be suitably used.

The adjustment member allows the bracket to have a varying length, making it usable in a wider range of applications. That is, it expands the bracket's scope of application.

II. Storage Rack System

Example 7

As shown in FIGS. 62 to 64, the present application provides a storage rack system 1 including upright columns 300, horizontal beams 400, brackets 100 as discussed above and carrier components arranged on the brackets 100.

The horizontal beams 400 are usually fixed to a vertical surface, such as a wall surface or a panel surface. The horizontal beams 400 are generally conventional standard products, which are elongate in shape. In use, the horizontal beams 400 are often fixed to a vertical surface and not relocated once fixed. The structure of the storage rack system can be structurally modified mainly by adding new upright columns 300, or removing or relocating some upright columns 300. Therefore, the upright columns 300 are detachable and movable. Each bracket 100 is connected, by the connecting portion on its one end, to an upright column 300. In some embodiments, the brackets 100 may also be connected to the horizontal beams 400. The structurally different mating portions of the brackets 100 can be connected to carrier components of different structures. For example, in the example shown in FIG. 26, carrier components including mesh shelves 210, drawers 240, plate-like shelves 230 and hanging hooks 250 can be arranged on the brackets 100. Carrier components of different structures may be arranged on opposite sides of one or more brackets 100. For example, as shown in part X of FIG. 26, a bracket 100 is connected to a mesh shelf 210 on one side and to a drawer 240 on the other side. As shown in port Y of FIG. 26, a plate-like shelf 230 is arranged on and connected to a bracket 100, and a hanging hook 250 is arranged under and connected to the bracket 100.

It will be understood that the storage rack system may be provided with carrier components of the same single structure, which may be replaced with carrier components of a different structure without requiring replacement of the brackets 100.

As shown in FIGS. 6 and 8, the upright columns 300 define slots 301, and the lugs 1011 of the brackets 100 can fixedly engage in the slots 301.

Usually, the storage rack system 1 may include at least two upright columns 300 arranged in parallel at an interval. At least one bracket assembly 10, e.g., a plurality of bracket assemblies 10, may be arranged on each upright column 300, e.g., at intervals, in a heightwise direction of the upright column 300. As noted above, one or more carrier components 20 may be arranged on a single bracket assembly 10. Alternatively, a single carrier component 20 may be coupled to at least two bracket assemblies 10 arranged at the same height. In this way, the carrier component 20 can be more stably retained. For example, as shown in FIG. 64, the lowermost carrier component 20 in the storage rack system 1 horizontally spans three bracket assemblies at the same height.

Example 8

According to an eight embodiment, as shown in FIG. 65, a carrier component 20 is attached to a bracket 100 via a guide rail 600 in such a manner that it can be moved outwardly or inwardly in a lengthwise direction of the bracket 100. This not only allows a user to more easily pick up an item from the carrier component 20, but can also reduce the space that the storage rack system occupies. In some implementations, the carrier component 20 may be a container like a mesh basket.

As shown in FIG. 66, the bracket 100 has a fifth mating portion on its second side 103. The fifth mating portion includes a plurality of fifth notches 601 which are formed in the second side 103 at intervals in the lengthwise direction. As shown, according to this embodiment, the storage rack system includes the guide rail 600 including a guide rail body 608 and a plurality of engagement elements 602 protruding from the guide rail body 608. Each of the engagement elements 602 can engage in one of the fifth notches 601, thereby attaching the guide rail 600 to the bracket 100. The engagement of the engagement elements 602 and the fifth notches 601 can ensure stable and reliable attachment of the guide rail 600 to the bracket 100.

Referring to FIG. 66, each fifth notch 601 defines a first engagement portion 6011 and a second engagement portion 6012 respectively at its ends opposing in the +K direction.

In some implementations, as shown in FIGS. 67 and 68, the engagement elements 602 include rivets 603 each including a diametrically smaller portion 604 attached to the guide rail body 608 and a diametrically larger portion 605 joined to the end of the diametrically smaller portion 604 away from the guide rail body 608. The diametrically smaller portion 604 has a dimension smaller than or equal to a dimension of the fifth notches 601, and the diametrically larger portion 605 has a dimension greater than that of the fifth notches 601. In order to deploy the guide rail 600, the diametrically smaller portions 604 of the rivets 603 can be passed through openings of the fifth notches 601 and engaged with the first engagement portions 6011 of the fifth notches 601, while the diametrically larger portions 605 can prevent the engagement elements 602 from inadvertently disengaging from the fifth notches 601.

In some implementations, as shown in FIGS. 69 to 71, the engagement elements 602 includes engagement hooks 606, which can be inserted into the fifth notches 601 and engage the first engagement portions 6011 thereof. Of course, in other implementations, both the rivets 603 and the engagement hooks 606 may be provided on the guide rail body 608. The engagement of the rivets 603 or engagement hooks 606 with the first engagement portions 6011 of the fifth notches 601 enable easy and convenient assembly without needing the use of additional fasteners such as screws or bolts.

In some implementations, referring to FIGS. 70 and 71, the guide rail 600 further includes stoppers 607 protruding from the guide rail body 608. In the direction in which the carrier component 20 is slidable, the second engagement portion 6012 and the first engagement portion 6011 at opposite ends of each fifth notch 601 are engaged with one of the stoppers 607 and one of the engagement elements 602, respectively. The engagement of the engagement elements 602 with the first engagement portions 6011 of the fifth notches 601 is established before the engagement of the stoppers 607 with the second engagement portions 6012 of the fifth notches 601. By doing so, the engagement elements 602 cannot move within the fifth notches 601, avoiding fall off of the carrier component 20 from the guide rail 600 due to inadvertent disengagement of the engagement elements 602 from the fifth notches 601. Thus, the guide rail 600 can be more reliably attached to the bracket 100. Meanwhile, wobbling of the guide rail 600 relative to the bracket 100 can be prevented, additionally stabilizing the guide rail 600 and the carrier component 20. In order to detach the carrier component 20 and the guide rail 600, the stoppers 607 may be disengaged from the fifth notches 601, allowing the engagement elements 602 to move within the fifth notches 601. After that, the engagement elements 602 may be disengaged from the fifth notches 601, allowing the guide rail 600 and the carrier component 20 to be removed from the bracket 100. In some implementations, as shown in FIG. 66, the stoppers 607 and the engagement elements 602 engage in different fifth notches 601. That is, the engagement elements 602 engage the first engagement portions 6011 of some fifth notches 601, and the stoppers 607 engage the second engagement portions 6012 of other fifth notches 601.

The number of fifth notches 601 may be determined, as required. Two, three or four fifth notches 601 may be provided. The plurality of fifth notches 601 may be provided at any suitable locations, depending on the arrangement of the engagement elements 602 and stoppers 607 of the guide rail 600, as long as it is ensured that all the engagement elements 602 and the stoppers 607 can engage in the fifth notches 601. The present embodiment is not particularly limited in this regard. Although the carrier component 20 is shown as an open mesh basket, it will be understood that it may be in any other suitable form that allows it to be attached to the bracket 100 through the guide rail 600. The present embodiment is not limited to any particular configuration of the carrier component 20.

It is to be noted that the foregoing embodiments are merely several representative embodiments of the present invention and are not intended to limit the scope of the invention in any sense.
