For example, a user may attach a replacement cap 50 for different look of the slider. The cap 50 may also be permanently fixed to the pulling member.
As shown in Figs. 2 and 3, the slider 100 may be in a resting or moving state. In the resting state, the pull tab 20 does not receive pulling force and does not transmit pulling force to the slider body. In the moving state, the pull tab 20 transmits the pulling force to the slider body 10. Returning to Fig. 8, the pintle 21 is disposed in the channel 14 and may transmit the pulling force to the pulling member 12. In certain embodiments, the walls 13 of the pulling member 12 receive the pulling force and the cap 50 may be configured not to receive the pulling force. In certain embodiments, both the walls 13 and the cap 50 may receive the pulling force.
Fig. 9 illustrates an exploded view of the slider body 10, pulling member 12 and cover 50 of an exemplary slider 100 consistent with the disclosed embodiments. As shown in Fig. 9, a front platform 151 may be disposed close to the front end 101 and a rear platform 161 may be disposed close to the rear end 102 in the groove 131. A first receiving structure 154 may be disposed on the front platform 151. In certain embodiments, the first receiving structure 154 may be a recess on the wall of the platform 151 at the front end 101. When the slider 100 is assembled, the first receiving structure 154 may interact with the first attaching member 503 to attach the cap 50 to the pulling member 12.
The first protruding block 17 may be disposed on the platform 151, and the second protruding block 18 may be disposed on the platform 161. The transverse dimension of the block 17 and the block 18 may be smaller than that of the platform 151 and the platform 161, respectively. Thus, a first sliding groove 171 may form between the block 17 and the wall 13, and a second sliding groove 181 may form between the block 18 and the wall 13.
As shown in Fig. 9, the channel 14 has a first cross transverse wall 141 and a second transverse wall 142. The wall 141 is on the platform 151 and the wall 142 is on the platform 161. The cross section of the channel 14 and the aperture 132 may be in any appropriate shape. In certain embodiments, the walls 141 and 142 of the channel 14 incline outwardly from the bottom to the top. The cross section of the channel 14 may thus have a small bottom and a larger top.
The slider 100 may include the locking opening 15. The opening 15 penetrates the upper wing 11 and the platform 151 vertically. The middle section of the wall 141 may be removed to accommodate the opening 15. The slider 100 may also include the chamber 16. The chamber 16 may be disposed within the platform 161. The chamber 16 may be formed by removing certain portion of the platform anterior to the block 18. The chamber 16 is connected to the channel 14 through an opening 144 on the wall 142.

The locking lever 30 may include a pivot end 32 towards the rear end 102 and a positioning component 331 towards the front end 101. The positioning component 331 may be connected to a locking prong 33.
As shown in Figs. 2 and 3, the locking lever 30 may be configured to dispose the pivot end 32 in the chamber 16 after the slider 100 is assembled. The positioning component 331 may be configured to be against a wall 152. The locking prong 33 may thus be configured to move vertically in the opening 15.
Returning to Fig. 9, the plate spring 40 is an elastic structure that is configured to be disposed on the top of the locking lever 30. The plate spring 40 may be in any appropriate shape. In certain embodiments, the plate spring 40 is an elongated rectangular plate. In certain embodiments, the plate spring 40 may include a first receiving groove 41 at the end close to the front end 101 and a second receiving groove 42 at the end close to the rear end 102. The receiving groove 41 may match the contour of the block 17 and the receiving groove 42 may match the contour of the block 18. Thus, when the spring 40 is placed on top of the platform 151 and the platform 161, the block 17 may contact the receiving groove 41 and the block 18 may contact the receiving groove 42. The spring 40 may maintain its position by the interaction between the receiving grooves 41 and 42 and the blocks 17 and 18, respectively. The plate spring 40 may be made of any appropriate material, such as elastic steel.
The transverse dimension of the receiving grooves 41 and 42 may be similar to that of the block 17 and 18 respectively, and the transverse dimension of the spring 40 at the two ends may be similar to that of the platform 151 and 161 respectively. Thus, a first sliding portion 411 and a second sliding portion 421 may fit into the sliding groove 171 and 181 respectively. The sliding portions 411 and 421 may slide on the sliding groove 171 and 181 respectively. As shown in Fig. 3, when the pull tab 20 is pulled, the plate spring 40 receives the pushing force from the locking lever 30. The sliding portions 411 and 421 slide inwardly on the sliding groove 171 and 181 and the plate spring 40 bends upwardly. When the pull force on the pull tab 20 is removed, the sliding portions 411 and 421 may slide outwardly on the sliding groove 171 and 181, respectively.
Fig. 10 illustrates an exemplary slider 200 consistent with the disclosed embodiments. As shown in Fig. 10, the slider 200 includes a slider body 10, a pull tab 20, and a cap 50.
