1. Field of the Invention
The present invention relates to a resilient device for garments, and more particularly to an improved spring clip for engaging buttons on shoulders straps on overalls.
2. Description of Related Art
In clothing industry, various fastening devices are being used in garments, jeans, overalls, and mostly used in suspenders.
In general, the resilient device is a button loop engaging the button project from the suspender. The resilient device can fasten or released from the button which freely dressing or removing the suspenders. The convenience of using should be one of the features for the subject product. In order to satisfy increasing requirement from the users, the subject product have been continuously improved. Currently, two conventional spring clips have been disclosed in published patent specification.
The first conventional spring clip is disclosed in the U.S. Pat. No. 5,005,269, invented by Nathan A. Hirsch. With reference to
The second conventional spring clip is disclosed in the U.S. Pat. No. 5,706,561, invented by Ronald Kipperman. With reference to
A main object of the present invention is to provide a spring clip with good elasticity and strength to mitigate the aforementioned problems.
According to the invention, a spring clip comprising:
The first member has a first pin and second pin substantially perpendicular to a body of the first member for respectively presenting the free ends from escaping from the chamber, and the second member has a first aperture and second aperture corresponding to the pins.
The first member further has at least one pin between the first and second pins, and the second member further has at least one aperture corresponding to the at least one pin.
The pins are respectively secured in the apertures by means of riveting.
The first member and second member each have two edges formed at two opposed sides and substantially perpendicular to the bodies thereof.
The encasement has a fan-like or quadrangular shape.
The encasement is made of metal or alloy, preferably zinc alloy.
The encasement is made of rigid plastic such as acetal resin or nylon plastic.
Therefore, the improved structure of the spring clip provides a good elasticity for a neck to hold a button and a durable encasement.
Other objects and advantages of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

With reference to
The first member 21 is provided with a first pin 212 and a second pin 214 to prevent the free ends 31, 32 of the wire loop 3 from escaping from the encasement. In this embodiment, the first member 21 is further provided with an additional pin 216. The first and second pins 212, 214 are respectively formed at two open ends of the first member 21, and the additional pin 216 is formed between the first and second pins 212, 214. Preferably, the three pins 212, 214, 216 constitute a triangle, of which the vertex is the additional pin 216 so as to position the free ends 31, 32 respectively in two bevel edges of the triangle. Namely, the first free end 31 is limited by the first pin 212 and additional pin 216, and the second free end 32 is limited by the second pin 214 and additional pin 216. As illustrated in
Three apertures 222, 224, 226 are defined in the second member 22 and corresponding to the pins 212, 214, 216, as shown in
According to the present invention, the quantity of the pins or apertures can be two or more than three, for example four, which is adapted to fasten and limit the free ends 31, 32 of the wire loop.
The button receiving portion 4 is defined by two outward bowed portions 35, 36 for receiving a button 7 therein. The neck 5 adjacent the button receiving portion 4 is defined by two inward bowed portions 33, 34 between which a narrowest width is smaller than an outer diameter of a stem 72 of the button 7.
In use, when the button 7 passes through the neck 5 to enter into or escape from the inward bowed portions 33, 34, the free ends 31, 32 are forced to move outwards. Therefore, the inward bowed portions 33, 34 are expanded outwards, and the width of the neck 5 are enlarged to allow the stem 72 to pass through the neck 5.
These elements of the encasement 2 can be made of zinc alloy by means of die-casting. Alternatively, if the encasement is made of rigid plastic, a common injection molding method can be used. The encasement 2 can be made with various shapes such as fan-like, quadrangular, or polygonal etc.
The spring clip made of zinc alloy can be color plated to provide an attractive appearance.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
