DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular, to FIG. 2 thereof, the preferred embodiment of the new and improved handle for a center punch embodying the principles and concepts of the present invention and generally designated by the reference number 10 will be described.

Specifically, it will be noted in the various Figures that the device relates to a new and improved handle for a center punch for providing a holder for a spring-loaded center punch so it can be used to break glass without causing injury to the hand. In its broadest context, the device consists of a spring-loaded center punch, a hollow tubular handle portion, a hollow tubular shaft portion, a shield portion, and a butt portion.

The device 10 includes a spring-loaded center punch 12 having a first end 14, a second end 16, and an intermediate extent therebetween 18. The second end 16 terminates in a pointed tip 20. The center punch 12 serves to break a glass window. The center punch 12 has a length of about five inches.

The device 10 contains a hollow tubular handle portion 24 having a first end 26, a second end 28, and an intermediate extent therebetween 30. The intermediate extent 30 has a foam padded handle 32 theresecured. The foam padded handle 32 provides the user with a comfortable means of holding the device 10.

The device 10 contains a hollow tubular shaft portion 36 having a first end 38, a second end 40, and an intermediate extent 42 therebetween. The first end 38 is integral with the second end 28 of the tubular handle portion 24. The second end 40 is adapted to slidably receive the first end 14 of the spring-loaded center punch 12 therein. The shaft portion 36 is fabricated of a hard, rigid plastic material. By receiving the the spring-loaded center punch 12 therein, only the pointed tip 20 is exposed in order to break a glass window.

A shield portion 46 is secured around the second end 28 of the tubular handle portion 24. The shield 46 is positioned outwardly of the foam padded handle 32. The shield portion 46 has a diameter about three times greater than the tubular handle portion 24 including the foam padded handle 32. The shield portion 46 serves to protect a user's hand from the glass broken by the spring-loaded center punch 12. The shield portion 46 serves to completely cover the user's hand as it grips the handle portion 24 protecting the hand from flying shards of glass.

The device 10 contains a butt portion 50 having a recess 52 formed therein. The recess 52 is adapted to receive the first end 26 of the handle portion 24 therein. The butt portion 50 is fabricated of a rigid rubber material to protect the user from the sharp edges of the first end 26 of the handle portion 24.

The present invention is a holder for a spring-loaded center punch so it can be used to break glass without causing an injury to the hand.

The holder is made of unbreakable or very strong plastic, and is tubular in shape, with a shield that protects the hand in which it is held. A long hole is provided in the outer end to accept the center punch. Only the hardened tip need be exposed. Such punches are about 5" long. Behind the shield, the handle has a rubber grip so it will not slip in the hand when the tool is used. Overall, the holder is about 10" in length.

The tool is designed for people who respond to emergencies, such as law enforcement officers and medical units. The spring-loaded center punch has been found to be very effective in breaking glass without sending shards flying through the air. It is used by placing against the glass and releasing the spring to drive the punch forward, enabling the point to shatter it. The tip acts as a stress raiser, permitting the force to be concentrated over a tiny area. Only a minimum amount of force is therefore required to create great stress on the glass.

This holder is needed because it will reduce the likelihood of injuries to the hand when the center punch is used. In emergencies, the ability to break glass quickly and positively can be very important, since some situations are life threatening, such as when people are trapped in submerged vehicles.

As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modification and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modification and equivalents may be resorted to, falling within the scope of the invention.
