Description

[Detailed explanation of the invention] This invention uses polymeric synthetic resin material as the material.
A slider for a slide fastener with an automatic locking device (hereinafter simply referred to as a slider) is a slider for a slide fastener with an automatic locking device, in which a lock claw for an automatic locking device is attached to the slider body for a slide fastener without a pull, which is manufactured in a single molding process by plastic processing by integral molding. The purpose is to create a simple slider that uses elastically deformable polymeric synthetic resin material and that eliminates the need for a handle by devising the structure of the slider. By attaching an elastic body with a separately manufactured slider lock pawl for an automatic locking device to the main body, it has good durability and a reliable automatic locking function. Our goal is to provide a slider with a simple and superior automatic locking device.

Most of the sliders with automatic locks manufactured and used in the past were mainly sliders with a handle, and many had a structure in which the lock was released by the action of a spring when the handle was operated, but the structure was complicated. The manufacturing process also had drawbacks, such as the large number of parts, the difficulty in assembling the slider, and the complexity of the equipment, especially when automatically assembling the slider. In this invention, a slider body with no pulls is obtained in one molding process using a polymer synthetic resin as a material, and a slider lock claw piece made of an elastic body with a lock claw is attached to this body. The above-mentioned drawbacks can be solved by installing the device.

The structure and operation of this device will be explained below with reference to the drawings attached to the specification, but the structure described as an essential component of the structure of this device in the claims of the utility model registration in the specification is Even if there are differences in the embodiment from those described in this specification, it goes without saying that the invention falls within the technical scope of this invention.

In Figures 1 to 3, A is a slider body without a puller made of a polymer synthetic resin material and molded in a single molding process by plastic working by integral molding. Examples of synthetic resin materials include polyacetal, P, B,
A material that can be elastically deformed, such as T, is used, but it is not limited to the exemplified materials, but may be selected from appropriate polymeric synthetic resin materials in relation to design factors such as the thickness and dimensions of the slider. 1 is the fuselage of the slider body A, 2 is the upper wing of the fuselage 1, 3 is the lower wing,
4 is a connecting column connecting the upper wing 2 and lower wing 3; 5 is an element 13 of a slide fastener chain (hereinafter simply referred to as chain) B formed by the above-mentioned wings 2 and 3, the connecting column 4, and a flange 10 to be described later. The Y-shaped guide groove 6, which serves as a running path, is a knob that is integrally provided on the upper surface of the upper wing 2 of the fuselage 1 of the slider body A, and is integrally provided with the fuselage 1. A vertical member in the direction of movement and a horizontal member perpendicular to the operating direction are connected to the vertical member to form a relatively tall T-shape, and the shape and structure are suitable for when operating the slider body A. It is not necessary to make the shape into a T-shape or specify a high height, and the shape of the knob 6 may be determined depending on the size of the slider body A. Reference numeral 7 denotes an operation plate that is integrally installed with the upper wing 2 of the slider body 1 via a thin wall portion L formed by the lower end of the lateral groove 8 provided near the rear end of the upper surface of the upper wing 2 (in the case of a flexible material, the lateral groove 8
(There is no need to place the operation plate on the upper surface of the upper wing 2 without providing a thin part L that is thinner than the thickness of the upper wing),
9 is a thin slider lock claw piece N shown in Fig. 4.
The connection column 4 is installed and stored from the base of the operation plate 7 along the rear end side of the upper wing 2 and near the top surface of the upper wing 2.
It has a structure in which a narrow and thin elastic body 15 of the thin slider lock pawl piece N shown in FIG. 4 is inserted into and attached to the upper wing. At this time, as shown in FIG. The portion that contacts the lower end of the horizontal groove 8 has a structure in which the slot 9 and the horizontal groove 8 communicate through a hole 17, and when the elastic body 15 is fitted, the end 16' of the cut and raised piece 16 engages with the hole 17. However, if the elastic body 15 is configured to be strongly pushed into the slot 9 as shown in FIG. There is no need for it. Furthermore, when the elastic body 15 is a linear spring 20 with both ends bent as shown in FIG. Form it so that it has a thickness slightly thicker than that of the hole 9, or
Or the thickness of the slot 9 (or the diameter of the hole in the case of a round wire)
be formed to have a thickness slightly thinner than that of the linear spring 20, or as shown in FIG. A protrusion 22 is provided. 10 is a flange that hangs integrally with the upper wing 2 from the lower surface of both sides of the upper wing 2 and encloses the Y-shaped guide groove 5; 11 is a flange that faces the upper wing 2 and the lower wing 3 facing the Y-shaped guide groove 5; This is a raised partition on the inside surface. and the fourth
Figures a, b, and c are the slider lock claw pieces N mentioned above.
4a and 4b show a narrow or thin rectangular elastic body 15 made of metal or hard synthetic resin material (in the case of metal material, a steel plate or a phosphor bronze plate). For example, polycarbonate, polyacetal, and engineering plastics such as P, B, and T are suitable as synthetic resin materials.Bend the ends of the springs at approximately right angles, and remove a part of the lower part of the bent springs. Cut it out to form the slider lock pawl 18. In example a, a part of the upper surface of the elastic body 15 is further punched out to form a cut-and-raised piece 1.
In example b, a protrusion 19 is provided on a part of the upper surface of the elastic body 15 using a punch or the like. Also,
In example c, one end of the linear spring 20 is bent into a U-shape, and the other end is bent downward to form the slider lock 18. 5 and 6 are a side view and a rear front view showing a partial cross section of the slider lock pawl N shown in FIG. 4a attached to the slot 9 of the slider body A shown in FIGS. In this figure, the elastic body 15 fitted from the rear end side of the slider in the slot 9 has an end 16' of the cut and raised piece 16 in the horizontal groove 9.
The lock pawl 18 is engaged with the lower part of the operation plate 7 in the hole 17 which is in contact with the lower end of the Y-shaped guide groove 5, and the lock pawl 18 projects toward the element running path of the Y-shaped guide groove 5. Note that the structure in which the elastic body 15 is provided with a frictional engagement portion H and press-fitted into the slot 9 is not limited to the protrusion 19 shown in FIG. It is also possible to implement a shallow sawtooth configuration or a wave-like bend in the longitudinal direction. In addition, simply selecting the thickness of the elastic body 15 to be a little thicker than the hole thickness of the slot hole 9, or making the thickness of the groove hole 9 a little thinner than the thickness of the elastic body 15, and press-fitting it can reduce the friction. In some cases, there is no practical problem in the case of ordinary clothing. When attaching the elastic body 15 by frictional engagement as described above, an appropriate adhesive having affinity with both the polymer synthetic resin that is the material of the slider body A and the elastic plate body 15 may be used if necessary. . Furthermore, FIGS. 6a and 6b are explanatory diagrams showing a state in which the slider lock piece N shown in FIG. 4c is attached to the slot 9 of the slider main body A shown in FIGS. 1 to 3. The elastic body 15 consisting of a linear spring 20 fitted from the rear end has a U-shaped portion in the slot 9.
It locks onto the inner protrusion 22 to prevent it from coming off.
In Figs. 5, 7 to 9, 12 is the tape of chain B, 13 is an element sewn to the tape 12 with sewing thread 14, and the illustrated one is a coil-shaped element, a zig-sag type element, etc. There is no problem in using conventionally known fastening teeth such as those made of polymer synthetic resin or metal. In FIG. 9, arrow S indicates that the elements of chain B are engaged when slider A is slid in the direction of the arrow, E is in the engaged state, F is in the separated state, and in FIG. 7, the symbol G is This figure shows how the tape 12 and element 13 of chain B are engaged in the Y-shaped guide groove 5 of the slider.

Since the slider of this invention has the above-mentioned configuration, in its normal state, that is, when the slider body A is not touched, the slider is located at the lower part of the operation plate 7 and protrudes from the lower surface of the upper wing 2 of the slider. The lock pawl 18 is fitted between the elements 13 at the rear of the Y-shaped guide groove 5 of the slider body A of the stringer on one side of the chain B to which the slider body A is attached. Although the slider body A is in the locked state as shown in Fig. 7, the person operating the slider body A holds the operating plate 7 and the knob 6 between his fingers, and applies force P toward the knob 6 by pressing the upper part of the operating plate 7 (Fig. 7). (Refer to) When pressed, the operation plate 7 will move into the groove 8.
The operating plate 7 is tilted to the state shown in FIG. 7 by the elasticity of the material of the slider main body A around the lower end portion L of the slider body A as a fulcrum. As the plate 7 inclines, the slider body A moves upward using the elasticity of the elastic plate 15 using the lower end of the groove 8 as a fulcrum, moving upward together with the upper wing 2, resulting in bending of the elastic plate 15. The slider lock pawl 18 at the tip of the slider pulls out from between the adjacent elements 13 and unlocks the sliding movement of the slider body A, so that when the operator presses the operation plate 7 toward the knob 6. If the slider body A is slid as it is, the slider body A can slide on the element 13 of the chain B and open/close the slide fastener. The same applies when automatic operation is performed.) Then, when the sliding operation of the slider body A is stopped at the desired position and the operation plate 7 is released from the knob 6, the operation plate 7 automatically returns to the self-holding position due to the elasticity of its material, and the slider lock pawl 18 is also integrated therewith. Then, the slider body A is automatically returned to the locked state by being fitted again between the elements 13 protruding from the rear part of the Y-shaped guide groove 5 of the slider body A.

As is clear from the above explanation of the structure and operation of this invention, the slider of this invention does not require a handle for sliding the slider, releasing the locking device, and applying the locking device, and the material of the slider body is elastically deformable. A simple structure is achieved by using polymeric synthetic resin and using a metallic spring plate material such as a steel plate, a highly elastic synthetic resin material, or a linear spring material as the elastic body that fits into the slot of the slider body. In terms of durability and functionality, we are able to provide a product that is comparable to conventional sliders with automatic stop devices that have a complex structure in which a spring is combined with a pull.At the same time, the slider body of this invention is made of a polymer synthetic resin material. Since it can be manufactured by plastic working in one molding process by integral molding, there are fewer manufacturing steps compared to the conventional slider with automatic locking device with a handle, and mass production is possible by molding. This has significant effects in terms of production and price.
