1. Field of the Invention
The present invention relates generally to sawing tools and more specifically, to a saw blade guard unit for use in cooperation with a handsaw, which can be rolled up and received in a casing at the handle of the handsaw, or pulled out of the casing to guard the teeth of the saw blade when the handsaw is not in use.
2. Description of the Related Art
Upon receiving or transporting a handsaw, the teeth of the saw blade must be covered with a strip-like guard to protect the teeth of the saw blade against accidental damage, maintaining normal functioning of the handsaw. A strip-like guard for this purpose is usually designed as an individual member separating from the handsaw, A user must keep the strip-like guard in the nearby place so that the strip-like guard can be quickly picked up for use when desired. However, because the strip-like guard is an individual member, it will get lost very easily.
The present invention has been accomplished in view of the above-noted circumstances. It is therefore an objective of the present invention to provide a saw blade guard unit, which can be mounted in the handle of a handsaw and can be alternatively set between a received position kept from sight or an extended position to guard the teeth of the saw blade of the handsaw.
To achieve this objective of the present invention, the saw blade guard unit, which is used in cooperation with a handsaw having a saw blade and a handle connected with the saw blade, comprises a flexible strip and a holder. The flexible strip has a head end, a tail end for positioning to a front portion of the saw blade of the handsaw, and a body between the head end and the tail end for guarding teeth of the saw blade of the handsaw. The holder is adapted for mounting to the handle of the handsaw. The holder is connected with the head end of the flexible strip and capable of rolling up the flexible strip. When the handsaw is not in use, the user can pull the tail end of the flexible strip outwardly and then fasten it to a front portion of the saw blade to have the teeth of the saw blade be guarded by the body of the flexible strip. When a user wants to use the handsaw, the user can disconnect the tail end of the flexible strip from the front portion of the saw blade for enabling the flexible strip to be rolled up by the holder.
In an exemplary embodiment of the present invention, the saw blade guard unit may further comprise a guide roller adapted for mounting to a bottom of the handle of the handsaw for guiding forward and backward movements of the flexible strip along the saw blade of the handsaw.
In an exemplary embodiment of the present invention, the holder is adapted for mounting in a casing of the handle of the handsaw. The holder has a reversible reel for rolling up the flexible strip. The reversible reel has a hook connected with the head end of the flexible strip.
In an exemplary embodiment of the present invention, the head end of the flexible strip may have a through hole into which the hook of the reversible reel of the holder hooks.
In an exemplary embodiment of the present invention, the tail end of the flexible strip may have an opening with which a retaining plate is engaged. The retaining plate has a positioning pin for fastening to the front portion of the saw blade of the handsaw.
Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood 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.
The present invention will become more fully understood from the detailed description given herein below and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention, and wherein:
As shown in
As shown in
Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. For example, the saw blade guard unit can be installed on the outside wall of the handle, or detachably attached to the handle of the handsaw. Accordingly, the invention is not to be limited except as by the appended claims.
