## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a slide rail mounting mechanism, and more particularly, to a slide rail mounting mechanism applicable to carried objects with different lengths.
2. Description of the Prior Art
Generally, a slide rail assembly at least comprises a first rail and a second rail. Wherein, the second rail can be moved to be at a retrieve position or an extension position relative to the first rail. The second rail is configured to mount a carried object, such as a chassis, drawer or the like.
U.S. Pat. No. 6,209,979 B1 discloses a slide rail assembly. As shown in FIG. 1 of U.S. Pat. No. 6,209,979 B1, a rail element of the slide rail assembly has a plurality of L-shaped slots 16 for mounting a plurality of corresponding mounting posts 14 of a chassis. Generally, when mounting the chassis by the above arrangement, the chassis must be lifted up to be right above the rail element, the mounting posts of the chassis are then aligned to all the L-shaped slots for mounting in a vertical drop-in manner, and the chassis is further moved horizontally. As such, the chassis can be mounted on the rail element without tools. However, such mounting method must align all of the mounting posts to all of the L-shaped slots. The slide rail assemble is applicable to the chassis with different lengths (for example, a longer chassis can has three mounting posts for mounting on the rail element, and a shorter chassis can has two mounting posts for mounting on the rail element), but it is not convenient to mount the chassis in the vertical drop-in manner.
U.S. Pat. No. 6,938,967 B2 discloses another slide rail assembly. As shown in FIG. 9 of U.S. Pat. No. 6,938,967 B2, a rail element of the slide rail assembly has a plurality of receiving slots 16 substantially in a U shape, for mounting a plurality of corresponding mounting posts 14 of a chassis. Generally, when mounting the chassis by the above arrangement, the chassis must be lifted up to be right above the rail element, and the mounting posts are then aligned to the receiving slots for mounting in a vertical drop-in manner. Since the receiving slots on the rail element are U-shaped slots, when a front end of the chassis is pressed by an external force, a rear end of the chassis may be tilted up. Therefore, when using the U-shaped receiving slot, an elastic engagement element is usually provided for one of the receiving slots. Through holding the mounting post of the chassis by the engagement element for preventing detachment of the mounting post from the receiving slot, stability of mounting the chassis to the rail element can be improved. However, when the chassis is going to be detached from the rail element, the user must apply a force to keep the engagement element outside the receiving slot, such that the chassis can be detached from the rail element. The above release operation is inconvenient. On the other hand, such design is mainly applicable to a chassis with a certain specification. When mounting a shorter chassis, since the receiving slot at a rear end of the rail element is in a U shape without any blocking feature, the rear end of the chassis may be tilted up when the front end of the chassis is pressed by an external force.
Therefore, the present invention is provided for solving the problems.

DETAILED DESCRIPTION
As shown in FIG. 1, a slide rail mounting mechanism of an embodiment of the present invention comprises a rail element 10, an adjustment element 12 movably mounted to the rail element 10, and a fixing element 14 configured to connect the rail element 10 and the adjustment element 12.
The rail element 10 has an upper wall 16a, a lower wall 16b, and a middle wall 18 extended and connected between the upper wall 16a and the lower wall 16b. A passage 20 is defined by the upper wall 16a, the lower wall 16b and the middle wall 18. In addition, the rail element 10 further has a plurality of slots, such as a first receiving slot 22, a second receiving slot 24 and a third receiving slot 26 in the present embodiment. The first receiving slot 22, the second receiving slot 24 and the third receiving slot 26 are separated from each other. The first receiving slot 22 is located between the second receiving slot 24 and the third receiving slot 26. The first receiving slot 22 and the second receiving slot 24 are substantially in a U shape or V shape. Specifically, the first receiving slot 22 is extended from a first portion of the upper wall 16a of the rail element 10 to a first portion of the middle wall 18 of the rail element 10, and the second receiving slot 24 is extended from a second portion of the upper wall 16a of the rail element 10 to a second portion of the middle wall 18 of the rail element 10. On the other hand, the third receiving slot 26 is substantially in an L shape or J shape different from the shapes of the first receiving slot 22 and the second receiving slot 24. Specifically, the third receiving slot 26 is extended from a third portion of the upper wall 16a of the rail element 10 to a third portion of the middle wall 18 of the rail element 10. In short, the first receiving slot 22, the second receiving slot 24, and the third receiving slot 26 are formed between the upper wall 16a and the middle wall 18 of the rail element 10. Wherein, the first receiving slot 22 has a first part 28a and a second part 28b communicated with each other.
FIG. 2 and FIG. 3A further illustrate arrangement relationship between the adjustment element 12 and the rail element 10. In the present embodiment, the adjustment element 12 is movably mounted to the middle wall 18 of the rail element 10, and is located in the passage 20 of the rail element 10. The adjustment element 12 has an upper part 34, a lower part 36, a main body part 38 and a blocking part 40. The upper part 34 is located adjacent to and/or contacts the upper wall 16a of the rail element 10. The lower part 36 is located adjacent to and/or contacts the lower wall 16b of the rail element 10. The main body part 38 is extended and connected between the upper part 34 and the lower part 36. The blocking part 40 is extended from the main body part 38 to be correspondingly adjacent to the first receiving slot 22. The blocking part 40 can be directly or indirectly connected to the main body part 38. Wherein, one of the adjustment element 12 and the rail element 10 has an elongated hole 42. In the present embodiment, the adjustment element 12 has the elongated hole 42 for example. The fixing element 14 passes through the elongated hole 42 for connecting the rail element 10 and the adjustment element 12.
As shown in FIG. 3A and FIG. 3B, the adjustment element 12 is capable of moving relative to the rail element 10 between a first position P1 and a second position P2. Specifically, when the adjustment element 12 is located at the first position P1, a part of the adjustment element 12, such as the blocking part 40, does not extend to be in the first receiving slot 22 between the first part 28a and the second part 28b. When the adjustment element 12 is adjusted to move from the first position P1 to the second position P2, the blocking part 40 extends to be in the first receiving slot 22 between the first part 28a and the second part 28b and occupies part of space in the first receiving slot 22.
As shown in FIG. 4, the slide rail mounting mechanism is applicable to a carried object 44. The carried object 44 (such as a chassis of an electronic apparatus, a drawer, or the like) has a first length L1 and comprises a plurality of mounting elements, such as a first mounting element 46, a second mounting element 48, and a third mounting element 50 for illustration in the present embodiment.
As shown in FIG. 5A and FIG. 5B, the first receiving slot 22, the second receiving slot 24 and the third receiving slot 26 of the rail element 10 are respectively configured to mount the first mounting element 46, the second mounting element 48 and the third mounting element 50 of the carried object 44. Specifically, when the carried object 44 is going to be mounted to the rail element 10, a user can place the third mounting element 50 of the carried object 44 into the third receiving slot 26 obliquely. Since the third receiving slot 26 is substantially in an L shape or J shape, the third mounting element 50 can be blocked in the third receiving slot 26 after the third mounting element 50 enters the third receiving slot 26. On the other hand, since the adjustment element 12 can be adjusted to be located at the first position P1, the blocking part 40 of the adjustment element 12 does not extend to be in the first receiving slot 22 between the first part 28a and the second part 28b, such that the first mounting element 46 and the second mounting element 48 of the carried object 44 can be respectively mounted in the first receiving slot 22 and the second receiving slot 24. Particularly, if the carried object 44 is going to be detached from the rail element 10, the user only needs to apply a force to a position on the carried object 44 near the second mounting element 48 to lift up the carried object 44, such that the third mounting element 50 can be accordingly detached from the third receiving slot 26 of the rail element 10, so as to release the carried object 44 from the rail element 10.
As shown in FIG. 6, the slide rail mounting mechanism is applicable to a carried object 200. The carried object 200 has a second length L2 (the second length L2 is different from the first length L1 of the carried object 44 in FIG. 4, for example, the second length L2 is shorter than the first length L1). The carried object 200 comprises a first mounting element 202 and a second mounting element 204 capable of being mounted on the rail element 10.
As shown in FIG. 7A and FIG. 7B, the first receiving slot 22 and the second receiving slot 24 of the rail element 10 are respectively configured to mount the first mounting element 202 and the second mounting element 204 of the carried object 200.
When the carried object 200 is going to be mounted to the rail element 10, the adjustment element 12 can be adjusted in advance by the user to move relative to the rail element 10 to the second position P2, in order to allow the blocking part 40 of the adjustment element 12 to extend to be in the first receiving slot 22 between the first part 28a and the second part 28b, to occupy part of space in the first receiving slot 22. Meanwhile, the first receiving slot 22 is changed to a substantially L shaped or J shaped slot by the blocking part 40. When mounting the carried object 200 to the rail element 10, the user can obliquely place the first mounting element 202 of the carried object 200 into the second part 28b of the first receiving slot 22 from the first part 28a of the first receiving slot 22. On the other hand, the second mounting element 204 of the carried object 200 can be accordingly dropped in the second receiving slot 24 for mounting. With assistance of the blocking part 40 of the adjustment element 12, the first mounting element 202 of the carried object 200 can be prevented from being directly detached from the first receiving slot 22 in a vertical manner. Particularly, the user also can respectively mount the first mounting element 202 and the second mounting element 204 of the carried object 200 to the first receiving slot 22 and the second receiving slot 24, and then adjust the adjustment element 12 to move from the first position P1 to the second position P2, in order to block the first mounting element 202 of the carried object 200 by the blocking part 40 of the adjustment element 12. Therefore, the position of the adjustment element 12 can be adjusted according to actual requirements of the user without limitation.
The slide rail mounting mechanism of the present invention is applicable to the carried objects with different lengths. Especially in a condition of not changing the structure of the rail element, the position of the adjustment element can be adjusted according to requirements to block the mounting element of the carried object to stay in the receiving slot of the rail element.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
