[0048] While the invention is illustrated and described herein with reference to particular embodiments, the invention should not be limited to the details shown, rather various modifications may be made to the details within the range and scope of equivalents of the claims and without departing from the invention.

[0049] The descriptions of directions such as “front”, “back”, “up” and “down” involved in this article are only for the convenience of understanding. The present invention is not limited to these directions but can be adjusted according to actual conditions.

[0050] Reference Figure 1A to Figure 2 The extraction aid 100 according to the present application is generally described as follows: The extraction aid 100 includes a mounting member 140 , a handle 110 , a claw 120 , and the extraction aid 100 may further include a locking member 130 .

[0051] The mounting member 140 is used to mount the extraction aid 100 as a whole to the first object 200. The first object 200 is, for example, a hard disk, a circuit board, a tray, etc., which can be inserted into or removed from the second object 300. The second object 300 is, for example, a chassis, a cabinet, etc. In use, the first object 200 is usually heavy, so the extraction aid 100 is required to insert or remove the first object 200. The extraction aid 100 is mounted to the first object 200, so the first object 200 can be moved by the extraction aid 100.

[0052] The handle 110 can pivot between a closed state and an open state relative to the mounting member 140 to separate the first object 200 from the second object 300. During the pivoting process of the handle 110, the handle 110 acts as a lever, thereby assisting the user in inserting or removing the first object 200.

[0053] More specifically, the handle 110 includes a rod portion 111 , a first hole 112 , a first slot 113 , a claw hole 114 , a flange 115 , a second hole 116 , and a second slot 117 .

[0054] The rod 111 is the main body of the handle 110 and may be in a sheet shape. The first hole 112 and the first slot 113 are disposed at one end of the rod 111 , and the second hole 116 and the second slot 117 are disposed at the other end of the rod 111 .

[0055] The handle 110 is pivotally connected to the mounting member 140 via the first hole 112. For example, the shaft 150 axially passes through the mounting member 140 and the first hole 112 to allow the handle 110 to pivot axially relative to the mounting member 140. In other embodiments, the handle 110 can be pivotally mounted to the mounting member 140 by other known means.

[0056] The flange 115 extends outwardly in the radial direction of the first hole 112 at the first end, but this is not necessary, and the flange 115 can deviate from the radial direction of the first hole 112. The flange 115 can extend in the axial direction to form a thickened portion, thereby increasing the strength of the flange 115. Figure 4B ) towards the open state (combined with reference Figure 7B ) during the movement, the flange 115 abuts against the second object 300 to apply a force to separate the first object 200 from the second object 300.

[0057] The first slot 113 extends outward at the end of the handle 110 and is open outward. The first slot 113 may extend along the radial direction of the first hole 112, but this is not necessary. The claw 120 can be slidably inserted into the first slot 113. The first slot 113 is provided with claw holes 114 on both axial sides. The first pin 160 passes through the claw holes 114 and through the slide groove 122 of the claw 120 to limit the sliding range of the claw 120 relative to the first slot 113. Figure 5B , Figure 6B , the first elastic member 170 is disposed between the claw 120 and the bottom of the first slot 113, and biases the claw 120 to extend from the first slot 113. In other embodiments, the slide slot 122 is not disposed on the claw 120, but is disposed on the handle 110. Accordingly, the handle 110 is not provided with a claw hole 114, but a similar hole is provided on the claw 120. The first pin 160 passes through the slide slot 122 of the handle 110 and the hole of the claw 120 to limit the sliding range of the claw 120 relative to the handle 110.

[0058] That is, the claw 120 is at least partially inserted into the handle 110, and the claw 120 in the extended state extends further out of the handle 110 than in the retracted state. The claw 120 at least partially extends out of the handle 110, and as the handle 110 pivots relative to the mounting member 140. During the pivoting of the handle 110, the claw 120 can abut against the second object 300 to drive the first object 200 to be inserted into the second object 300.

[0059] The claw 120 includes a body 121 and abutment 123. The body 121 can be slidably inserted into the handle 110, and the abutment 123 is located at the end of the body 121 away from the handle 110 and can be engaged with the second object 300. The abutment 123 can have an inclined surface in a direction away from the flange 115 so as to abut against the first object 200 and retract into the handle 110, which will be described in detail below.

[0060] It should be understood that the flange 115 and the claw 120 extend perpendicularly to the axial direction of the handle 110, and are spaced apart along the rotation direction of the handle 110. During the process of the handle 110 moving toward the open state and toward the closed state, the flange 115 and the claw 120 respectively abut against the second object 300. Therefore, the extraction aid 100 of the present application can not only assist the user to eject the first object 200 from the second object 300, but also assist in stably inserting the first object 200 into the second object 300.

[0061] Since the claw 120 pivots with the handle 110 relative to the mounting member 140, the claw 120 also pivots relative to the first object 200. The claw 120 may interfere with the first object 200 on its pivot path, such as interfering with the frame 220, the slide rail (not shown) or the wall (not shown) of the first object 200. Therefore, the claw 120 needs to engage the second object 300 and needs to have a pivot path that avoids the first object 200. In the non-retractable claw design, a certain distance is required between the first object 200 and the second object 300 to meet the above conditions, which is not conducive to a compact application environment.

[0062] Therefore, in the present application, the claw 120 has a retractable feature, and in particular, can be at least partially retracted into the handle 110 during the pivoting process (i.e., pivoting together with the handle 110), thereby reducing the pivoting path occupied by the claw 120 to avoid the first object 200. Therefore, the extraction aid 100 of the present application is suitable for compact application environments.

[0063] Specifically, the claw 120 is connected to the handle 110 and can be in a retracted state (combined with reference to Figure 6B ) and the stretched state (combined with reference Figure 5B When the handle 110 is in the closed state, the claw 120 is in an extended state to engage with the second object 300, and when the handle 110 is pivoted between the open state and the closed state, the claw 120 can move to a retracted state to avoid the first object 200.

[0064] Back to Figure 2The locking member 130 is pivotally connected to the second hole 116 of the handle 110, that is, the locking member 130 and the claw 120 are arranged at opposite ends of the handle 110. The second slot 117 extends in a direction away from the rod 111 and is open outward. The locking member 130 is at least partially accommodated in the second slot 117. The second pin 180 passes through the second hole 116 and through the locking member 130 to allow the locking member 130 to pivot relative to the handle 110. The locking member 130 can be in a locked position relative to the handle 110 (combined with reference to Figure 4C ) and unlocked position (combined with reference Figure 5C ), and can be engaged with the column 210 of the second object 300 when in the locked position. Therefore, the locking member 130 is locked to the first object 200 when the handle 110 is in the closed state. For example, the locking member 130 has a hook portion 131 to lock to the column 210 of the first object 200. Therefore, the locking member 130 can keep the handle 110 in the closed state.

[0065] The second elastic member 190 is disposed between the bottom end of the second slot 117 and the locking member 130, and biases the locking member 130 toward the locking position. The user can manually move the locking member 130 to the unlocking position.

[0066] The direction of the second pin 180 can be parallel to the axis 150 or can be inclined relative to the axis. In other embodiments, the locking member 130 can be pivotally connected to the handle 110 by other means known in the art.

[0067] Reference Figure 3 and Figure 4A In use, two extraction aids 100 according to the present application can be arranged opposite to each other and respectively mounted to the first object 200. More specifically, the mounting member 140 of each extraction aid 100 is close to the outside of the first object 200, and the locking member 130 is close to the inside of the first object 200, so that the first object 200 can be ejected or inserted more stably.

[0068] Reference 4A to 7C The operation of the extraction aid 100 according to the present application will be described.

[0069] First refer to FIG. 4A to FIG. 4C , wherein the first object 200 is inserted into the second object 300, and the handle 110 is in a closed state. At this time, the handle 110 is close to the first object 200, and the hook 131 of the locking member 130 is engaged with the column 210 of the first object 200 to lock the handle 110 in the closed state (see Figure 4B The locking member 130 is kept engaged to the post 210 under the action of the second elastic member 190 .

[0070] The abutting portion 123 of the claw 120 extends from the handle 110 under the action of the first elastic member 170 and abuts against the lateral inner side of the second object 300. Therefore, the extraction aid 100 and the first object 200 on which the extraction aid 100 is installed cannot be separated from the second object 300.

[0071] When the first object 200 needs to be removed, the user rotates the locking member 130 to disengage the post 210. FIG. 4A to FIG. 4C The state shown transitions to FIG. 5A to FIG. 5C At this time, the hook portion 131 of the locking member 130 is disengaged from the column 210 (see Figure 5B ), allowing the handle 110 to pivot relative to the mounting member 140 (and the first object 200).

[0072] from FIG. 5A to FIG. 5C In the state shown in FIG. 1 , the user pivots the handle 110 toward the open state (at this time, the handle 110 may not be completely in the open state), so that the extraction aid 100 transitions to the open state. FIG. 6A to FIG. 6C During this process, the flange 115 of the extraction aid 100 abuts against the outer side of the second object 300 (see Figure 6B ), thereby extracting the extraction aid 100 and the first object 200 on which the extraction aid 100 is installed from the second object 300. At this time, the claw 120 pivots to a position interfering with the first object 200 (for example, the frame 220 of the first object 200). The claw 120 abuts against the frame 220 and retracts into the handle 110, thereby reducing the pivot path occupied by the claw 120. Since the abutting portion 123 of the claw 120 is provided with an inclined surface in a direction away from the flange 115, the claw 120 can abut against the frame 220 more smoothly and retract into the handle 110. That is, when the handle 110 is switched between the open state and the closed state, the claw 120 abuts against the first object 200 to move to the retracted state.

[0073] from FIG. 6A to FIG. 6C In the state shown, the user continues to pivot the handle 110 toward the open state, so that the extraction aid 100 transitions to the open state. FIG. 7A to FIG. 7C At this time, the handle 110 reaches the open state, and the first object 200 moves a distance to the outside of the second object 300 under the action of the extraction aid 100. The claw 120 passes the position of interfering with the frame 220 of the first object 200, and thus returns to the extended state under the action of the first elastic member 170. At this time, the user can completely pull the first object 200 out of the second object 300 through the handle 110.

[0074] When the user needs to insert the first object 200 into the second object 300, the above steps are performed in reverse order. FIG. 7A to FIG. 7CStarting from the state shown, the user pivots the handle 110 toward the closed state so that the claw 120 abuts against the inner side of the second object 300 to insert the extraction aid 100 and the first object 200 mounted with the extraction aid 100 into the second object 300. During this process, the claw 120 abuts against the frame 220 of the first object 200 and retracts into the handle 110, thereby avoiding interference with the first object 200. Finally, the extraction aid 100 reaches FIG. 4A to FIG. 4C In the state shown, the handle 110 is in a closed state, the claw 120 passes over the frame 220 and returns to the extended state, and the locking member 130 is engaged with the column 210.

[0075] In summary, the present application provides an extraction aid 100 having a retractable claw 120, so as to avoid the first object 200 during the pivoting process of the handle 110. Therefore, the extraction aid 100 of the present application can be used in a compact environment, wherein no spacing is required between the first object 200 and the second object 300 to avoid the pivoting path of the claw 120.

[0076] Although preferred embodiments have been shown and described herein, it should be understood that these embodiments are provided as examples only. Those skilled in the art will appreciate that many modifications, changes and substitutions will not deviate from the spirit of the present invention.
