Description
Background of the Invention
1. Field of the Invention
The present invention relates to an adjustable belt fastener and more particularly, to an improved adjustable belt fastener including female and male fastener members attached to opposite ends of a belt, the female fastener member containing a series of slots and the male fastener member having a spring biased tongue for selectively engaging in one of the slots depending upon the desired length of the belt.
2. Description of Related Art
Various types of adjustable belt fasteners are known in the art. Such conventional adjustable belt fasteners suffer from a number of problems such as, for example, they are difficult to lock in and unlock from both ends of the belt because the locking pin is not firmly engaged since the pin can readily break away from the bore. Furthermore, such conventional fasteners are complicated in structure, expensive to manufacture, difficult to use, and readily break away from the belt.
Summary of the Invention
Accordingly, it is an object of the present invention to provide an adjustable belt fastener, which eliminates the above problems encountered with conventional adjustable belt fasteners.
Another object of the present invention is to provide an adjustable belt fastener which includes a male fastener member having a spring biased tongue for engaging with one of a series of or slots of a female fastener, the male and female fastener members being attached to both ends of the belt.
A still further object of the present invention is to provide an adjustable belt fastener which is simple in structure, inexpensive to manufacture, durable in use, and refined in appearance.
Other objects and further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. It should be understood, however, that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
Briefly described, the present invention is directed to an adjustable belt fastener which includes a male fastener member attached to one end and a female fastener member attached to the other end of the belt, the female fastener member having a series of slots and the male fastener member having a spring biased tongue which can be inserted into or released from the slot for locking, unlocking, and changing the length of the belt.

FIG. 3 is a cross-sectional view of FIG. 2 taken along line 3--3; and
FIG. 4 is an enlarged perspective view of the adjustable belt fastener in a locking position according to the present invention.
Detailed Description of the Preferred Embodiments
Referring now in detail to the drawings for the purpose of illustrating preferred embodiments of the present invention, the adjustable belt fastener 10 as shown in FIGS. 1, 2, and 3, comprises a male fastener member 11 having a tongue 20 attached to a first end portion 25a of belt 25, and a female fastener member 22 having a plurality of slots 23 attached to a second end portion 25b of the belt 25, which can be made of leather.
The fastener member 11 includes a large opening 12 and a small opening 13 disposed on an inner surface thereof, a pair of supports 15 extending from both front sides of the large opening 12, an operating plate body 17 having a pair of legs 19 for pivotally engaging with the pair of supports 15 through pivotal pins 16, and a pair of springs 21 for biasing the operating plate 17 containing tongue 20 into selective engagement with one of said slots 23.
The operating plate body 17 which includes the tongue 20 has a handle disposed at a front end portion and a rear end portion thereof. Therefore, the tongue 20 and the operating plate body 17 mate with the small opening 13 and the large opening 12, respectively. The fastener member 11 can be firmly attached to the first end 25a of the belt 25 by first fixing members 14. The spring 21 has a V-shaped configuration (FIG. 2).
As shown in FIGS. 2 and 3, each female fastener member 22 is provided with recess 26 of the second end portion 25b of the belt 25 which includes a series of slots 23 which are equally spaced along the female fastener member 2. Each female fastener member 22 is attached to the recess 26 through second fixing member 24. The first and second fixing members 14 and 24 are punched into the belt. The female fastener member 22 has 1 to 3 members, preferably 2 members for controlling the flexibility of the second portion 25b of the belt 25.
As shown in FIGS. 2, 3, and 4, the adjustable belt fastener 10 according to the present invention operates as follows. The two belt end portions 25a and 25b are locked together by the elongated female fastener members 22 and the male fastener member 11. At this time, after the user pushes the handle 18 of the operating plate body 17 with a finger, if the pushed finger is released from the handle 18, the tongue 20, as like a hook, firmly and automatically locks in one of the slots 23 of the female fastener member 22 (FIGS. 3 and 4).
Alternatively, when the locked belt 25 is unlocked by disengaging the end portions 25a and 25b from each other, the handle 18 is pushed by the finger. Also, when the user wants to change the length of the locked belt 25, the handle 18 is pushed and stopped by the finger so as to adjust the length of the belt 25.
Since the male fastener member 11 has the hollow space 27, the second end portion 25b having the female fastener member 22 can be smoothly inserted into and engaged with the hollow space 27 thereof. Also, a plurality of the separated female fastener members 22 are attached on the recess 26 of the second end portion 25b of the belt 25, so that the second end portion 25b is very flexible even if the female fastener member 22 is attached thereto.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
