cap 50 for different look of the slider. The cap 50 may also be
permanently fixed to the pulling member.
[0027] 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.
[0028] 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.
[0029] 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.
[0030] 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.
[0031] 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.
[0032] The locking lever 30 includes a lever body 31. In certain
embodiments, the lever body 31 may be curved. As shown in FIG. 9,
the lever body 31 is curved outwardly. 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.
[0033] 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.
[0034] 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.
[0035] 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.
[0036] 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. The slider
body 10 includes an upper wing 11, a front end 101 and a rear end
102. A pulling member 12 is placed on the upper wing 11. In certain
embodiments, the pulling member 12 maybe integrated in the upper
wing 11. The pulling member 12 includes a transverse channel 14.
The pull tab 20 has a pintle 21. The pintle 21 is disposed in the
transverse channel 14. When the pull tab 20 is pulled, the pulling
force may move the slider 200 along the zipper.
[0037] FIG. 11 illustrates an exemplary process 600 of making an
exemplary slider 100 consistent with the disclosed embodiments. As
shown in FIG. 11, the slider body 10 with the upper wing 11 is
provided (602). The pulling member 12 with two walls 13 is attached
on the upper wing 11 (604). In certain embodiments, the pulling
member 12 with two walls 13 is integrated on the upper wing 11. The
pulling member 12 with the two walls 13 may also be removably
attached to the upper wing 11. The wall 13 has an aperture 132 and
the two apertures 132 on two walls 13 form the transverse channel
14. The two walls 13 form the assembly groove 131. The pull tab 20
with the pintle 21 is provided and the pintle 21 is disposed in the
transverse channel 14 (606). The locking lever 30 and the plate
spring 40 may be assembled within the assembly groove 131 (608).
The cap 50 is disposed on the top of the pulling member 12 to
enclose the locking lever 30 and the plate spring 40 within the
assembly groove 131 (610).
[0038] The process 600 may be completed without using press
riveting. The pull tab 20 may be directly disposed in the pulling
member 12. In addition, the assembly groove 131 is formed on the
pulling member 12. The locking lever 30 and the plate spring 40 may
be disposed in the groove 131 by insertion. The cap 50 may be
snapped on the groove 131 to enclose the locking lever 30 and the
plate spring 40. The whole process 600 is quick and convenient.
Thus, the efficiency of making the slider 100 is improved. The
process 600 may be completed manually or automatically on an
assembly device.
[0039] While various embodiments in accordance with the present
invention have been shown and described, it is understood that the
invention is not limited thereto. The present invention may be
changed, modified and further applied by those skilled in the art.
Therefore, this invention is not limited to the detail shown and
described previously, but also includes all such changes and
modifications. For example, the size, shape, and appearance of
slider according to the present disclosure may be changed to adjust
the use of the slider on different items.
[0040] A slider consistent with the disclosed embodiments may offer
several benefits. A slider consistent with the disclosed
embodiments includes a pulling member with two walls on an upper
wing of a slider body and a pull tab is directly disposed within
the pulling member. Because the pulling force may be directly
exerted on the walls, the pulling member may bear great force.
Further, the pulling member with two walls may be integrated in the
upper wing and may bear greater force transmitted through the pull
tab. Thus, a user may pull the pull tab with greater force.
[0041] Further, an assembly groove is formed on the pulling member
and a locking lever and a plate spring may be assembled within the
assembly groove. A cap covers the assembly groove and encloses the
locking lever and the plate spring within the slider. The assembly
of the slider body may not need press riveting and the assembly
process is convenient and efficient. The manufacturing efficiency
is thus improved.
