Welcome to my site.
This project was developed by a former Engineer and now a patent agent assistant studding towards LLM degree. Seeing new inventions is very interesting to me. I created this site to outlines my favorite inventions along with inventions that I believe have potential.

Handle of a saw

by Chen, Wen-Ger;


FIELD OF THE INVENTION

The present invention relates to a handle structure, and more particularly, to a handle of a saw, wherein the handle having an enclosed shape with a slit defined in an underside thereof so as to receive the saw blade therein.

BACKGROUND OF THE INVENTION

A conventional saw is shown in FIG. 1 and includes a handle 10 and a saw blade 11 which is connected to the handle 10. When using the saw, the user's handle holds the handle 10 and exerts a downward force to the saw blade 11 toward the object such as a wooden board 12. When the wooden board is cut by the saw, the inertial force of the downward force to the saw could make the hand holding the handle 10 suddenly hit the board 12 to hurt the fingers of the user's hand. Furthermore, the hand holding the handle 10 is exposed so that when operating the saw, the hand could be hit by other machines located beside the board to be cut.

The present invention provides the saw having an O-shaped handle so that fingers is protected by the handle and will not be hit. Besides, the handle further has a slit defined in an underside thereof so as to receive the saw blade and two side slots communicate with the slit so as to easily proceed maintenance for the saw blade via the two side slots.

SUMMARY OF THE INVENTION

In accordance with one aspect of the present invention, there is provided a saw comprising a saw blade and a handle which has a curved top portion and a bottom portion connected between two ends of the curved top portion. The curved top portion has the first end thereof connected to the saw blade and the bottom portion includes two frames with a slit defined between the two frames. Each of the two frames has a slot defined therethrough which communicates with the slit through which the saw blade is received between the two frames.

An object of the present invention is to provide a saw which protects the user's hand.

Another object of the present invention is to provide a saw wherein the saw blade is able to be received in the handle and conveniently accessed via slots of the bottom portion of the handle.

Further objects, advantages, and features of the present invention will become apparent from the following detailed description with appropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 2 to 4, the saw in accordance with the present invention comprises a saw blade 10 having a toothed side 11 and a handle 2. The handle 2 has a curved top portion 20 and a bottom portion 22 which is connected between two ends of the curved top portion 20 so that the handle 2 is an enclosed handle and the user's hand 30 may hold the cured top portion 20 and the fingers are protected by the bottom portion 22. The curved top portion 20 has the first end thereof connected to the saw blade 10 and the second end thereof having an aperture 21 defined therethrough. The bottom portion 22 includes two frames 220 and a slit 221 defined between the two frames 220 so that the saw blade 10 is received between the two frames 220 via the slit 221. Each of the two frames 220 has a slot 222 defined therethrough which communicates with the slit 221 as shown in FIG. 4.

It is to be noted that the toothed side 11 of the saw blade 10 is conveniently accessed via the two slots 222 when the saw blade 10 is received between the two frames 220. Therefore, the toothed side 11 of the saw blade 10 is easily lubricated or proceeded maintenance via the slots 222. When using the saw, the fingers of the user is protected by the bottom portion 22 so that when an object is cut into two sections, the inertial force of the saw will let the bottom portion 22 hit other things, not the user's fingers.

The invention is not limited to the above embodiment but various modification thereof may be made. It will be understood by those skilled in the art that various changes in form and detail may made without departing from the scope and spirit of the present invention.
