Description

Supporting device

Technical Field

The present invention relates to a supporting device, and more particularly, to a supporting device for a rack.

Background

For example, U.S. patent No. 8,727,138 B2 discloses a slide capable of being tool-lessly mounted to or removed from a rack, which can be used to support a load (e.g., a cabinet of electronic equipment). The two ends of each slide rail can be mounted to the front and rear upright frame rails (posts) of the frame by respective lock assemblies. When two pins of the lock assembly longitudinally penetrate into the holes of the upright frame rail, and a first locking arm and a second locking arm of the lock assembly are respectively in a locking position through the elasticity of the elastic part to lock the upright frame rail (as shown in fig. 7A of the patent), the slide rail can be installed and locked on the frame; alternatively, a user may manually operate a release handle to actuate the first and second locking arms from the locked position to an unlocked position (as shown in FIG. 7B of the patent) to allow the two pins to exit the holes of the upright frame rails to allow the slide rail to be removed from the frame.

For example, U.S. patent No. 8,770,528 B2 discloses a support bracket assembly that may be mounted to a front column and a rear column of a rack by a front bracket and a rear bracket. The front bracket and the rear bracket have substantially the same structural configuration, for example, the front bracket includes a plurality of connecting members and a fastening member, the connecting members can longitudinally penetrate into the holes of the machine column, and the fastening member enables (a fastening part of) the fastening member to lock the machine column by the elastic force of an elastic foot, so that the support frame assembly is mounted on the machine frame.

As can be seen from the above, the two patents disclose that the locking arm or the fastening member can be locked to the frame by an elastic force, which means that if the locking arm or the fastening member is no longer locked to the frame, the locking arm or the fastening member must be moved from the locking position to an unlocking position against the elastic force to remove the slide rail or the support frame assembly from the frame, especially if the front and rear brackets need to be manually released from the elastic force, which is not convenient for users.

With the market demands and different rack types, how to develop a different product becomes an issue worth discussing.

Detailed Description

As shown in fig. 1 and 2, a carrier 20 according to an embodiment of the present invention can be mounted to a rack by a pair of supporting devices 22, and the carrier 20 has a front portion 20a and a rear portion 20b. Further, the rack has a left side and a right side having substantially the same structural configuration. For example, the left side of the frame includes at least one column, such as a first column 24 (e.g., a front column) and a second column 26 (e.g., a rear column), but the implementation is not limited thereto. The first post 24 and the second post 26 have substantially the same structural configuration. For example, the first column 24 and the second column 26 each include a plurality of mounting holes 28 spaced apart along the height of the first column 24 and the second column 26. On the other hand, the pair of support means 22 have substantially the same structural configuration. Each support device 22 includes a longitudinal portion 30, at least one first mounting portion 32, and an elastic member 34. Preferably, the supporting device 22 further comprises a supporting portion 36 bent with respect to the longitudinal portion 30, the supporting portion 36 is substantially vertically connected to the longitudinal portion 30, and the supporting portion 36 is used for supporting the bottom of the supporting object 20.

It should be noted that, in the coordinates shown in fig. 1 and fig. 2, the X-axis direction is a longitudinal direction, the Y-axis direction is a transverse (or lateral) direction, and the Z-axis direction is a vertical direction (or a height direction of the first column 24 and the second column 26). Wherein, the X axis, the Y axis and the Z axis are mutually vertical directions.

As shown in fig. 3, 4 and 5, the mounting holes 28 of the first post 24 and the second post 26 have substantially the same structural configuration. Further, each mounting hole 28 is defined by a profile of a hole wall, for example, the mounting hole 28 is defined by a lower hole wall W1, an upper hole wall W2, a front hole wall W3 and a rear hole wall W4 (as shown in fig. 3), but the embodiment is not limited thereto.

At least one first mounting portion 32 of the support device 22 and the resilient member 34 are disposed on the longitudinal portion 30. In this embodiment, the at least one first mounting portion 32 is exemplified by a plurality, but is not limited in implementation; the elastic member 34 is provided with a second mounting portion 35, and the second mounting portion 35 is, for example, a protrusion, but is not limited in implementation.

Preferably, the longitudinal portion 30 of the supporting device 22 has a first side S1 and a second side S2 opposite to each other. The first mounting portion 32 includes a first extension K1 and a second extension K2. The first extension K1 connects the longitudinal portion 30, and the first extension K1 extends transversely (or laterally) beyond the second side S2; the second extension K2 is bent relative to the first extension K1, and here, the second extension K2 is substantially vertically connected to the first extension K1. The first extension K1 and the second extension K2 together form a hole wall of the mounting hole 28, which can be hooked to one of the mounting holes of the first column 24, for example, a lower hole wall W1 of the mounting hole 28 of the first column 24, so that the first mounting portion 32 can be mounted to a first predetermined position L1 (shown in fig. 4) of the first column 24.

Preferably, the longitudinal portion 30 of the supporting device 22 has a first end 30a and a second end 30b (such as a front end and a rear end, but not limited to), the first mounting portion 32 is adjacent to the first end 30a of the longitudinal portion 30, and the longitudinal portion 30 is further provided with at least one auxiliary mounting portion 38 adjacent to the second end 30b of the longitudinal portion 30. In this embodiment, the number of the auxiliary mounting portions 38 is the same as the number of the first mounting portions 32, the auxiliary mounting portions 38 have substantially the same structural configuration as the first mounting portions 32, and the auxiliary mounting portions 38 are mounted to the second post 26 in substantially the same manner as the first mounting portions 32 are mounted to the first post 24. Further, the auxiliary mounting portion 38 can be hung to a hole wall of the mounting hole 28 of one of the mounting holes of the second column 26 of the rack, for example, to the lower hole wall W1 of the mounting hole 28 of the second column 26, so that the auxiliary mounting portion 38 can be mounted to the first predetermined position L1 of the second column 26 (as shown in fig. 4).

On the other hand, the elastic element 34 includes a connecting portion 40, a guiding portion 42 and an elastic portion 44 disposed between the connecting portion 40 and the guiding portion 42. The connecting portion 40 is connected (e.g., fixedly connected) to a predetermined portion 43 of the first side S1 of the longitudinal portion 30; the elastic portion 44 is tilted at a predetermined angle (as shown in fig. 5) relative to the first side S1 of the longitudinal portion 30; the guiding portion 42 is bent toward the first side S1 of the longitudinal portion 30 relative to the elastic portion 44 (as shown in fig. 5), and the guiding portion 42 includes an inclined surface or an arc surface, but is not limited in implementation.

Preferably, the longitudinal portion 30 includes a through hole 46 communicating the first side S1 and the second side S2, the second mounting portion 35 is disposed on the elastic portion 44 of the elastic member 34, and the second mounting portion 35 can pass from the first side S1 to the second side S2 through the through hole 46. The second mounting portion 35 is positioned to correspond to one of the mounting holes 28 (shown in FIG. 4) of the first post 24.

Preferably, when the first mounting portion 32 is hung to the hole wall (e.g., the lower hole wall W1) of the mounting hole 28 of the first column 24, the first extension K1 of the first mounting portion 32 is supported by the hole wall (e.g., the lower hole wall W1), and the second extension K2 of the first mounting portion 32 has a lateral distance with the first column 24, so as to allow the supporting device 22 to be laterally displaced relative to the rack (as shown in fig. 4).

As shown in fig. 6 and 7, the supporting device 22 is mounted (or suspended) on the first column 24 and the second column 26 of the rack via the first mounting portion 32 and the auxiliary mounting portion 38, and the elastic element 34 is in a non-locking state X1 (e.g., an unlocking state, as shown in fig. 6). When the elastic element 34 is in the unlocked state X1, the elastic portion 44 of the elastic element 34 tilts by the predetermined angle (as shown in fig. 6) relative to the first side S1 of the longitudinal portion 30, and the position of the second mounting portion 35 corresponds to one of the mounting holes 28 of the first column 24 (as shown in fig. 7, the second mounting portion 35 does not yet penetrate into the mounting hole 28 of the first column 24). Further, the support 20 can be mounted to the supporting device 22 in a predetermined direction D. During the installation process, the rear portion 20B of the carrier 20 contacts the guiding portion 42 of the elastic member 34 (as shown in fig. 6), so as to facilitate a portion (e.g. the side edge L) of the carrier 20 to pass over the elastic member 34, and the bottom B of the carrier 20 can be partially supported by the supporting portion 36 (as shown in fig. 6 and 7). As can be seen from fig. 6 and 7, when the elastic member 34 is in the unlocked state X1 (as shown in fig. 6), the second mounting portion 35 is away from the first mounting portion 32 (as shown in fig. 7), for example, the second mounting portion 35 and the first mounting portion 32 are offset from each other in the vertical direction (Z-axis direction).

As shown in fig. 8 and 9, when the first mounting portion 32 is mounted to the first predetermined position L1 of the first column 24 of the rack (e.g., the first mounting portion 32 is hung on the lower hole wall W1 of the mounting hole 28 of the first column 24, as shown in fig. 9), and a force F is applied to the elastic member 34 (as shown in fig. 8), the elastic member 34 can be switched from the unlocked state X1 to the locked state X2, so that the second mounting portion 35 is mounted to a second predetermined position L2 of the first column 24 of the rack (e.g., the second mounting portion 35 has penetrated into the mounting hole 28 of the first column 24 at this time, as shown in fig. 9), so as to prevent the first mounting portion 32 from being separated from the first predetermined position L1 of the first column 24 of the rack (e.g., prevent the first mounting portion 32 from being separated from the lower hole wall W1 of the mounting hole 28 of the first column 24 in a height direction H, as shown in fig. 9), thereby locking the supporting device 22 to the rack. Preferably, when the second mounting portion 35 is mounted to the second predetermined position L2 of the first column 24 of the rack, the mounting gap between the second mounting portion 35 and the upper hole wall W2 of the mounting hole 28 is smaller than the extension length of the second extension K2 of the first mounting portion 32, so as to prevent the first mounting portion 32 from being detached from the first predetermined position L1 of the first column 24 of the rack (as shown in fig. 9). The first predetermined position L1 and the second predetermined position L2 are located in the same mounting hole 28. In detail, the first predetermined position L1 is an installation position, and the second predetermined position L2 is a locking position.

Further, the carrier 20 can be pushed in the predetermined direction D to be completely mounted to the supporting device 22. During the mounting process, the portion (e.g. the side L) of the supporting object 20 can be used to apply the force F and abut against the elastic portion 44 of the elastic member 34 (as shown in fig. 8, at this time, the elastic portion 44 of the elastic member 34 accumulates an elastic force opposite to the direction of the force F), so that the elastic member 34 is switched from the unlocked state X1 to the locked state X2, and the second mounting portion 35 is mounted to the second predetermined position L2 of the first column 24 of the rack (e.g. the second mounting portion 35 has been inserted into the mounting hole 28 of the first column 24 at this time, as shown in fig. 9), so as to prevent the first mounting portion 32 from being detached from the first predetermined position L1 of the first column 24 of the rack (e.g. prevent the first mounting portion 32 from being detached from the lower hole wall W1 of the mounting hole 28 of the first column 24 in the height direction H, as shown in fig. 9), thereby enabling the supporting device 22 to be firmly locked to the rack. When the carrying object 20 is further moved to a fully retracted position in the predetermined direction D, the bottom B of the carrying object 20 can be completely supported by the supporting portion 36 of the supporting device 22 (this portion can be referred to as fig. 1). In addition, as can be seen from fig. 8 and 9, when the elastic member 34 is in the locked state X2 (as shown in fig. 8), the second mounting portion 35 is close to the first mounting portion 32 (as shown in fig. 9), for example, the second mounting portion 35 and the first mounting portion 32 are close to or aligned with each other in the vertical direction (Z-axis direction).

It should be noted that when the first mounting portion 32 is mounted to the first predetermined position L1 of the first pillar 24 of the rack (for example, the first mounting portion 32 is mounted to the lower hole wall W1 of the mounting hole 28 of the first pillar 24), and the elastic member 34 is not applied with the force F (for example, the side L of the carrying object 20 is not abutted against the elastic portion 44 of the elastic member 34; or, after the carrying object 20 is dismounted from the supporting device 22), the elastic portion 44 of the elastic member 34 releases the elastic force to return to the unlocked state X1 from the locked state X2, so that the second mounting portion 35 is not mounted to the second predetermined position L2 of the first pillar 24 of the rack, for example, the second mounting portion 35 is separated from the mounting hole 28 of the first pillar 24 of the rack, so as to allow the first mounting portion 32 to be separated from the first predetermined position L1 of the first pillar 24 of the rack in the height direction H, so that the first mounting portion 32 can be separated from the mounting hole 28 of the first pillar 24 of the rack, and the second mounting portion 38 can be separated from the auxiliary mounting hole 26 of the rack. That is, the support device 22 can be easily detached from (the first and second posts 24, 26 of) the frame.

As shown in fig. 10, a supporting device 200 according to another embodiment of the present invention is illustrated, and the supporting device 200 according to the other embodiment is substantially different from the supporting device 22 according to the previous embodiment in that: the supporting device 200 does not include the elastic member 34 of the previous embodiment (i.e., the second mounting portion 204 of the supporting device 200 is not disposed on the elastic member 34). Specifically, the first mounting portion 202 and the second mounting portion 204 of the supporting device 200 are both directly disposed on the longitudinal portion 206. Wherein the first mounting portion 202 includes a first extension K1 'and a second extension K2', the first extension K1 'connects the longitudinal portion 206, and the first extension K1' laterally extends beyond the second side S2 of the longitudinal portion 206; the second extension K2 'is bent relative to the first extension K1', and here, the second extension K2 'is substantially perpendicularly connected to the first extension K1'. On the other hand, the second mounting portion 204 extends laterally beyond the second side S2 of the longitudinal portion 206, and the second mounting portion 204 is a protrusion, for example. The first extension K1' of the first mounting portion 202 has a first transverse length T1 relative to the second side S2 of the longitudinal portion 206, and the second mounting portion 204 has a second transverse length T2 relative to the second side S2 of the longitudinal portion 206, which is smaller than the first transverse length T1.

As shown in fig. 11 and 12, the first extension K1 'and the second extension K2' of the first mounting portion 202 together form a hook capable of being hung to a hole wall of one of the mounting holes 28 of the first column 24, for example, hung to the lower hole wall W1 of the mounting hole 28 of the first column 24, so that the first mounting portion 202 can be mounted to the first predetermined position L1 of the first column 24.

When the first mounting portion 202 is hung on the hole wall (e.g., the lower hole wall W1) of the mounting hole 28 of one of the mounting holes of the first column 24, the first extension K1 'of the first mounting portion 202 is supported by the hole wall (e.g., the lower hole wall W1), and a transverse distance T (as shown in fig. 12) is provided between the second extension K2' of the first mounting portion 202 and the first column 24, so as to allow the supporting device 200 to be laterally displaced relative to the rack. For example, the support device 200 can be in a first position P1 (shown in fig. 11) or a second position P2 (shown in fig. 12) relative to the frame.

Further, when the supporting device 200 is laterally displaced from the first position P1 (shown in fig. 11) to the second position P2 (shown in fig. 12) relative to the rack, the second mounting portion 204 can be mounted to a second predetermined position L2 of the first column 24 of the rack, for example, the second mounting portion 204 can be inserted into another mounting hole 28' of the first column 24 (shown in fig. 12) to prevent the first mounting portion 202 from being disengaged from the first predetermined position L1 of the rack (for example, prevent the first mounting portion 202 from being disengaged from the lower hole wall W1 of the mounting hole 28 of the first column 24 in the height direction H, as shown in fig. 12), thereby locking the supporting device 200 to the rack. The first predetermined position L1 and the second predetermined position L2 of the present embodiment are different mounting holes 28. The first predetermined position L1 is an installation position, and the second predetermined position L2 is a lock position.

Preferably, when the second mounting portion 204 is mounted to the second predetermined position L2 of the first column 24 of the rack, the mounting gap between the second mounting portion 204 and the upper hole wall W2 of the other mounting hole 28 'is smaller than the extension length of the second extension K2' of the first mounting portion 202, so as to prevent the first mounting portion 202 from being disengaged from the first predetermined position L1 of the first column 24 of the rack (as shown in fig. 12).

Preferably, when the first mounting portion 202 is mounted to a first predetermined location L1 of the first column 24 of the rack (e.g., the first mounting portion 202 is hung to a lower wall W1 of the mounting hole 28 of the first column 24) and the second mounting portion 204 is not mounted to a second predetermined location L2 of the rack (e.g., the second mounting portion 204 has not yet been inserted into another mounting hole 28' of the first column 24, as shown in fig. 11), the first mounting portion 202 is allowed to be disengaged from the first predetermined location L1 of the first column 24 of the rack.

Preferably, the supporting portion 208 of the supporting device 200 is used for supporting the carrying object 20, and the carrying object 20 can drive the supporting device 200 to move from the first position P1 to the second position P2 laterally relative to the frame. For example, when the carrier 20 is mounted to the supporting device 200 in the predetermined direction D, a portion (e.g., the side L) of the carrier 20 can push against the supporting device 200, so that the supporting device 200 is laterally displaced from the first position P1 (shown in fig. 11) to the second position P2 (shown in fig. 12) relative to the frame.

Preferably, one of the longitudinal portion 206 and the carrier 20 may be provided with a guiding feature 207, such as a slant or a curved surface (as shown in fig. 10 and 11), and here, the guiding feature 207 is provided adjacent to the first end 206a of the longitudinal portion 206, for example, so as to facilitate the carrier 20 to be able to push against the supporting device 200 via the guiding feature 207 to laterally displace from the first position P1 (as shown in fig. 11) to the second position P2 (as shown in fig. 12) during the process of mounting the carrier 20 to the supporting device 200 in the predetermined direction D.

Preferably, the auxiliary mounting portion 210 can be hung on a wall of one of the mounting holes 28 of the second column 26, for example, a lower wall W1 of the mounting hole 28 of the second column 26, so that the auxiliary mounting portion 210 can be mounted on the first predetermined position L1 of the second column 26 (as shown in fig. 11 and 12).

From the above description, it can be seen that the enhanced efficacy and advantages of the present invention are:

a. in the embodiment of the present invention, when the first mounting portion 32 is mounted to the first predetermined position L1 of the rack and the elastic member 34 is applied with the force F, the elastic member 34 can be switched from the unlocked state X1 to the locked state X2, so that the second mounting portion 35 is mounted to the second predetermined position L2 of the rack to prevent the first mounting portion 32 from being disengaged from the first predetermined position of the rack, thereby locking the rack by the supporting device 22.
