ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a slide fastener with water/air tightness, having a pair of concave row convex rows formed of thermoplastic resin adapted to mesh with each other, which is generally called a rail-shaped fastener. More particularly, it relates to a meshing type slide fastener, wherein an engaging device or an opening device is provided at the respective end portions of the concave row and the convex row so as to enable right and left parts thereof to be separated, and by engagement of the engaging device and sliding of a slider, the concave row and the convex row can be meshed with each other.

FIG. 14
shows a conventional slide fastener having a pair of concave and convex rows

′ made of thermoplastic resin, which is disclosed in Japanese Utility Model Publication No. 48-36003. As shown in
FIG. 14
, in the slide fastener, end portions of the pair of meshing concave row
1
′ and convex row
2
′ disposed on the right and left sides are fixed with a metal stop device
20

1
′,
2
′ are meshed with each other.
FIG. 15
shows another conventional meshing-type slide fastener having a pair of concave/convex and convex/concave meshing rows
1
″,
2
″, each having a plurality of hook pieces made of thermoplastic resin on one surface thereof, which is disclosed in Japanese Utility Model Publication No. 30-443. In the slide fastener, a box-shape metal stop device
20
″ is attached to an end portion of one of the meshing rows
1
″,
2
″, and a projection for preventing a slip-out of a slider is formed integrally at the other end portion. The end portion of the one of the meshing rows
1
″,
2
″ on which the box-shape metal stop device
20
″ is attached and the end portion of the other meshing row which is to be inserted into the box-shape metal stop device
20
″ are formed in a flat shape. Then, the other meshing row is inserted into the box-shape metal stop device
20
″, so that by sliding the slider, the both meshing rows
1
″,
2
″ can be meshed with and separated from each other.
The meshing type slide fastener of the first example as shown in
FIG. 14
is a generally known one. Because the pair of concave and convex rows
1
′,
2
′ disposed on the right and left of the slide fastener are fixed by the metal stop device
20
′ attached to the end portions while being in a meshing condition, the pair of meshed concave and convex rows
1
′,
2
′ cannot be separated completely. Therefore, there is a problem that its usage field is limited, so that this meshing type slide fastener cannot be used for clothes which is to be separated to right and left sections to be opened completely.
In the meshing type slide fastener of the second example as shown in
FIG. 15
, the box-shape metal stop device
20
″ is attached to the end portion of one of the meshing concave/convex and convex/concave rows
1
″,
2
″, each of which has a plurality of hook pieces, and the other meshing row is inserted into this box-shape fastening metal, so that the both meshing rows
1
″,
2
″ are meshed with each other. However, an operation for separating the right and left meshing rows
1
″,
2
″ is very complicated, so that smooth separation or meshing operation can not be achieved. Therefore, this meshing type slide fastener is far from being practical.
SUMMARY OF THE INVENTION
Accordingly, the present invention has been achieved in views of the above-described problems. An object of a first aspect of the present invention is to provide a meshing type slide fastener with an engaging device comprised of a pair of concave and convex rows of thermoplastic resin, which are adapted to be meshed with each other, in which the pair of concave and convex rows can be separated from or meshed with each other easily and smoothly by sliding of a slider. This slide fastener also has an engaging device provided integrally at terminal ends of the respective concave and convex rows for facilitating engagement and separation of the rows, so that the convex row can be inserted through a side of the slider or released therefrom.
In addition to the object of the first aspect, an object of a second aspect of the present invention is to provide a slide fastener with an engaging device, which has a specific configuration of a concave-row-meshing portion and a convex-row-meshing portion capable of exerting their function efficiently, so as to open or close the pair of concave and convex rows by the sliding of the slider and to enable insertion of the convex row through a side of the slider and meshed with the concave row or separated therefrom, thereby achieving a smooth operation of the slide fastener.
In addition to the object of the first or the second aspect, an object of a third aspect of the present invention is to provide a slide fastener with an engaging device in which the convex-row-meshing portion of the convex row can be inserted into the concave-row-meshing portion of the concave row easily through the side of the slider, so that a meshing function without any lost action can be achieved with the slider.
In addition to the object of the first aspect, an object of fourth and fifth aspects of the present invention is to provide a slide fastener with an engaging device in which the engaging device having female and male fastening members, which allow the end portions of the pair of concave and convex rows to be engaged with and separated from each other, is molded integrally with the pair of concave and convex rows by injection molding, thereby achieving effective production of the slide fastener.
In addition to the object of the first aspect, an object of the fourth and sixth aspects of the present invention is to provide a slide fastener with an engaging device which has a specific configuration of the engaging device to be attached onto the end portions of the pair of concave and convex rows, and in which the engaging device is capable of being attached to a concave-row-supporting portion and a convex-row-supporting portion firmly, and is provided with a female fastening member and a male fastening member that can be engaged with and separated from each other. The engaging device is welded, bonded or joined by pressing to each of the concave row and the convex row by simple means.
In addition to the object of the fourth aspect, an object of a seventh aspect of the present invention is to provide a slide fastener with an engaging device which has a structure for engaging the engaging device of the concave row with that of the convex row thereby achieving meshing between the concave row and the convex row more accurately.
In addition to the object of fourth, an object of an eighth aspect of the present invention is to provide a slide fastener with an engaging device which has a specific configuration of the female and male fastening members to be equipped on the engaging device so as to enhance coupling/separation function of the engaging device thereby improving the quality and function of the fastener.
In addition to the object of the fourth, an object of a ninth aspect of the present invention is to provide a slide fastener with an engaging device in which the engaging device are fixed to the end portions of the pair of concave and convex rows firmly by injection molding thereby having firm attaching strength.
In addition to the object of the fourth or the sixth aspect, an object of a tenth aspect of the present invention is to provide a slide fastener with an engaging device in which the engaging device to be attached onto the end portions of the pair of concave and convex rows are formed of thermoplastic resin so that they can be attached on the end portions of the pair of concave and convex rows accurately and easily without obstructing their meshing operation.
