The present invention relates to a slider for a slide fastener.

Conventionally, various kinds of sliders have been developed and used, which are roughly classified into lock type and non-lock type slides. Some of them were satisfactory, but most were not satisfactory for various reasons.

The most fundamental and important reason why most sliders are not satisfactory and sometimes defective in the past is the inadequate mounting position or shape of the handle attachment member that pivotally supports the handle on the slider fuselage or uncertainty. In other words, when the handle is pulled or twisted strongly, the handle attachment member may be displaced or released from the slider body or away from the handle.

This phenomenon is even more severe for sliders in which the handle attachment member is intended to serve as a maintenance member, such as for example in an automatically stationary slider. In the case of a handle attachment member having a defect as described above, the stop protrusion formed at the free end of the handle attachment member is deviated from its exact passage while moving in and out of the slider through the hole in the slider body, and thus Frequently, they become tight enough to render the slider inoperable.

The present invention aims to address the above-mentioned drawbacks, and its main object is to provide a slider for an improved slide fastener that is structurally robust and reliable in operation.

A more specific object of the present invention is to provide an improved slider having a handle attachment member and a means for keeping the handle in the correct position on the slider body so that they do not displace or disengage from the slider body.

The slider for a slide fastener according to the present invention is provided with a handle attachment member on its body, and at one end of the handle attachment member is composed of a narrow neck portion and shoulders on both sides of the neck portion, and a pair of grooves therebetween. The locking end for forming the shape extends downward, and the head is directed in the vertical direction at the other end of the handle attachment member. The upper side of the slider body has a support protrusion and a hole formed in the lower portion of the support protrusion and engaged with the head of the handle attaching member, and the diamond portion of the slider body is formed by a vertical side wall and a vertical vertical wall which are formed outwardly. The groove is installed.

A central portion of the vertical end wall is separated by a V-shaped groove, and a pair of engagement protrusions having a size coinciding with the groove of the handle attachment member protrudes in the horizontal direction. Pressing the engaging end portion on the engaging projection in the direction in which the side walls are close to each other causes the engaging projection to be caught by the neck of the handle attachment member so that the engaging end portion is fitted into the vertical groove between the side walls.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

In FIG. 1 a non-stationary slider 10 is shown. The body 11 of this slider consists of an upper piece 12 and a lower piece 13. One end of the upper piece 12 and the lower piece 13 are connected to each other by a diamond part 14, and they are arranged parallel to each other at a distance so that a passage of a fastener stringer (not shown) is provided therebetween. A Y-shaped passage 15 is formed. On the rear end portion 17 of the upper piece 12, there is a box-shaped support protrusion 16 and a hole 18 formed in the lower portion of the support protrusion 16 by punching the support protrusion 16 from the upper side.

The rear end portion 20 of the handle attachment member 19, which is roughly a-shaped, is substantially perpendicular to the upper portion 12, and a narrow head portion 21 protrudes downward from the end portion thereof. There are shoulders 22 on both sides of the head. The width of the head 21 is substantially the same as the width of the hole 18, the protruding distance of the head 21 is substantially the same as the thickness of the upper piece (12). In the state in which the slider 10 is assembled, the shoulder 22 is brought into contact with the outer surface of the upper piece 12 to coincide.

The straight middle portion 23 of the handle attachment member 19 is partially displaced, as at point 23 ', which is in contact with the flat upper surface 16' of the support projection 16 during assembly of the slider. . The engaging end 24 extends continuously downward from the middle part 23 in the direction opposite to the rear end of the handle attaching member 19. The engaging end 24 is a diamond portion 14 of the slider 10. It is inserted and fixed in the vertical groove 25 formed in the front end located.

A slender vertical portion 26 is formed in the locking end portion 24 of the handle attachment member 19, and the length of the vertical portion 26 is substantially the same as the height of the slider body tip. The vertical portion 26 is composed of a narrow neck portion 27, upper and lower shoulders 28 and 29 formed on both sides of the neck portion, and a pair of grooves 30 (31) formed therebetween.

The vertical grooves 25 of the slider body 11 extend perpendicularly to the upper and lower pieces 12 and 13 and open forward as shown. This vertical groove 25 is for the engaging end 24, more specifically, the vertical portion 26 of the locking end 24 is fitted, so that the vertical groove 25 is in the form of the locking end 24 And complementary. As clearly shown in FIG. 4, the vertical groove 25 is formed by a pair of side walls 32 and 33 and a flat vertical end wall 34 extending outward from the front end of the slider body. The central portion of 34 is vertically separated by the V-shaped auxiliary groove 35.

The purpose of the V-shaped auxiliary groove 35 will be described later. A pair of engaging projections 36 and 37 protrude horizontally from the vertical end wall 34 on both sides of the V-shaped groove 35, and the size of the engaging projections 36 and 37 is a recess of the handle attachment member 19. The same as the size of (30) and (31), respectively, and extends outward from the neck in the thickness direction of the neck (27).

The handle 38 has a rectangular hole 39 to engage the support protrusion 16 on the upper piece 12 and the rear end 20 of the handle attachment member 19, so that the handle 38 is known. It can be turned in a way.

When assembling the components of the slider 10 as described above, first, the vertical locking end 24 of the handle attachment member 19 is inserted into the vertical groove 25 so that the engaging projections 36 and 37 are recessed. 30 and 31, and upper and lower shoulders 28 and 29 contact the side walls 32 and 33 and the vertical end wall 34.

In this state, when the diamond portions 14 are pressed in opposite directions as shown by the arrows X and Y in FIG. 1, the locking end portions 24 are firmly caught in the vertical grooves 25. As shown in FIG. The open ends 32 'and 33' of each of the side walls 32 and 33 are opposed to each other inward so as to be located on the extensions 36 'and 37' of the respective engaging projections 36 and 37. Tightening is continued until the neck portion 27 of the handle attachment member 19 is fully engaged with the engagement projections 36 and 37 (see also FIG. 2).

This tightening action is easily performed by the presence of the V-shaped auxiliary groove 35, and the V-shaped auxiliary groove 35 is gradually narrowed as the tightening pressure is applied (see FIGS. 5 and 6). ).

If the locking end 24 located at the tip of the handle attachment member 19 is fixed in this way, the rear end 20 of the handle attachment member 19 is then fixed to the slider body 11 together with the handle 38. .

That is, the handle 38 is placed flat on the upper piece 12, and then the rear end 20 of the handle attaching member 19 passes through the rectangular hole 39 of the handle 38 to protrude downward. (21) is inserted into the hole 18 on the upper piece 12, and in this position, the lower surface 23 'toward the rear end 20 of the intermediate portion 23 of the attachment member 23 is placed on the upper portion of the box-shaped support protrusion 16. Abut the surface 16 '.

In such a fixed position, pressure is applied inwardly to the rear end 20 of the handle attachment member 19 such that a portion of the rear end 20 abuts against the bottom surface 16 '' of the support protrusion 16. Thus, the rear end 20 of the handle attachment member 19 is firmly fixed to the slider body 11 (see FIG. 3).

According to the slider having the structure as described above, the handle attachment member 19, the slider body 11, and the handle 38 can be firmly and permanently coupled, that is, the engaging projection 36 at the tip of the slider body 11 is formed. Engagement () 37 and the grooves (30) (31) prevent the vertical movement of the handle attachment member (19), while the engaging projection extension (36 ') and the side wall open ends (37', 32 ') Engagement with prevents the horizontal movement of the handle attachment member 33 '. In addition, the head 19 is also firmly engaged in the hole 18 of the upper body 12 of the slider body 11 as described above, so that the rear end 20 of the handle attachment member 19 is similarly prevented from moving. do.

7 and 8 show an auto stop slider 10 to which the principles of the present invention are applied. In this embodiment, two parts are further added: the stop member 40 and the spring member 41. The operation of these two members is well known. The handle attaching member 42 in the form of a hat or yoke exhibits a function corresponding to the handle attaching member 19 of FIG.

At one end of the handle attachment member 42, a vertical locking end 24 is formed, which is substantially the same as the locking end of the handle attachment member 19. The vertical groove 25 in the diamond portion 14 is engaged.

As shown in FIG. 7, in the vicinity of the diamond portion 14 of the upper piece 12 of the slider 10, there is a pair of holes 43 and 44 provided at intervals in the transverse direction to each other to stop the member 40. And a hole 47 near the rear end of the slider, when the stop member 40 is operated by the handle 49 according to a known method. It is adapted to accommodate a catch 48 that moves in and out of the slider passage 15. The handle 49 has a quadrangular hole 50, and also has a pivoting end 51 hingedly connected to an opening 52 extending laterally from the inside of the handle attachment member 42.

In the slider assembly as shown in FIG. 8, the handle 49 is placed on the upper piece 12, and the protrusions 45 and 46 of the stop member 40 are formed by holes 43 on the upper piece 12 ( 44 respectively, and the clamp 48 of the stop member 40 is formed on the upper piece 12 near the rear end of the slider 10 via the hole 50 of the handle 49. )

The spring member 41 is disposed between the stop member 40 and the handle attaching member 42, which typically biases the stop member 40 downward toward the slider 12, thus When the handle 49 is laid flat on the upper piece 12, the catch 48 is engaged with the fastener element in the slider passage 15. When the handle 49 is pivoted around the pivoting end 51, the catch 48 is released from the slider passage 15 against the biasing force of the spring member 41. Such facts are known in the art.

An important feature in the second embodiment as shown in FIGS. 7 and 8 is that the rear end of the handle attachment member 42 is fixed when the rear end of the handle attachment member 42 is fixed to the slider body 11. What is necessary is just to be able to bend the processus | protrusion 53 protruding downward from the inner side of the recessed part 54 in the last end part of the upper piece 12. The recess 54 is formed on the lower surface of the upper piece 12 by punching the slider upper piece 12 at the point 55.

9 to 12 show a further variant of the invention, i.e. a third embodiment. The third embodiment relates to an automatic stop slider, wherein the handle attachment member serves two roles as a connecting member and a stop member, that is, to fix the handle on the slider body and the slider on the fastener stringer. It stops and releases the stop. The vertical locking end 24 of the handle attachment member 56 is substantially the same as the locking end of the handle attachment member 19 in the first embodiment and the locking end of the handle attachment member 42 in the second embodiment. And, it is to be fitted in the vertical groove 25 in the manner described above.

As illustrated in FIG. 11, a pair of hook-like support protrusions 51 and 58 are provided at a distance from each other in the transverse direction near the diamond portion 14 of the upper portion 12 of the slider 10. The support protrusions 57 and 58 are projected upwardly so that the upper portion 12 of the slider is upwardly formed so that the openings 59 and 60 are formed in the lower portion thereof. The pair of shoulders 61 and 62 formed on both sides of the 24 can be accommodated. The upper piece 12 is also provided with another supporting protrusion 63 similar to the above-described supporting protrusions 57 and 58, which is provided near the rear end of the slider 10. The opening projection 64 is formed in the lower part of the support projection 63 so as to accommodate the clamp 65 formed at the rear end of the handle attachment member 56. The hole 66 formed near the clamp 65 of the handle attaching member 56 is for accommodating the upwardly projecting support projection 63 in the upper slider 12.

The handle 67 in the third embodiment is provided with an opening 68 and a trunnion-shaped pivoting end 69. The pivoting end 69 is provided with a handle attachment member 56. It is to be engaged with the lower surface of the body 70 and to allow the handle 67 to pivot about it.

The pivot end 69 is positioned such that the upper surface of the handle attachment member main body 70 is substantially flush with the upper surface of the handle 67 when the slider 67 is placed horizontally when the slider 10 is stopped. It is installed a little lower to make it possible.

Since the general structure of such a stationary slider is widely known, it will be understood without further explanation. The principle of the present invention is applied to the known slider in which the handle attachment member 56 is fixed to the tip end of the slider body 11 by the locking end 24 in the manner described in the first embodiment of FIGS. It is enough to explain.

As such, when the handle attachment member 56 and the slider body 11 are firmly and firmly coupled, the clamping member 65 located at the free end of the handle attachment member 56 can be maintained in the correct position and shape. When the 67 is operated in a conventional manner to stop and release the slider 10 on the fastener stringer, the clasp 65 can move without any obstacle into the opening 64 on the upper piece 12.
