Abstract

A saw handle adapted to have a blade engaged therewith and further including a gripping area to allow a user to firmly hold the saw handle, the saw further including a flexible guard member which is movably secured to the saw handle adjacent to the blade such that the flexible guard is movable to extend along the toothed edge of the saw blade to be attachable thereto for protection of the teeth of the saw blade as well as for protection of the surrounding environment from the teeth of the saw blade, the flexible guard being secured to the handle by way of a resilient retaining member such as a spirally wound recoil spring which will wind the flexible guard means automatically in a circular fashion within the handle whenever the guard itself is not being pulled outwardly for placement adjacent the toothed edge of the blade, the handle defining a recess into which the flexible guard and the resilient retaining member are located, the flexible guard possibly further including a hook eye adapted to slide into a slot defined by the blade at the forward edge thereof to hold the guard in fixed engagement with respect to the teeth of the blade, in this manner the automatically recoiling flexible blade guard will be retained in a somewhat remote location whenever the saw is in normal use and will be able to be withdrawn from the recess and placed in engagement with the teeth of the blade easily and quickly, the blade also preferably including a knife area for starting cuts as defined by the blade member.

Claims

1. A saw handle attachable to a saw blade having a toothed edge, said saw handle comprising:

(a) a handle means;

(b) means for attaching a saw blade to said handle means being located along an edge of said handle means;

(c) a gripping means located along another edge of said handle means to allow a user to firmly hold said handle means;

(d) a spirally wound recoil spring being fixedly secured at one end thereof to said handle means; and

(e) a continuously flexible guard means being elongated with one end connected to the other end of said spirally wound recoil spring and being wound around said spirally wound recoil spring in the withdrawn position and extendable therefrom to cover the saw blade toothed edge.

2. The handle as defined in claim 1 wherein said means for attaching a saw blade comprises a plurality of blade bolts extending through the saw handle and the saw blade.

3. The handle as defined in claim 1 wherein the saw handle defines a guard recess therein in which said flexible guard means and said spirally wound recoil spring are retained.

4. The handle as defined in claim 1 wherein said flexible guard means includes a hook eye member thereon securable to a slot on the saw blade to maintain said flexible guard means in the extended position in engagement with the toothed edge of the saw blade.
