Embodiment Construction

[0084] According to a preferred embodiment of the present invention, the hand saw guide 10 includes a guide plate 100 with a guide surface 105 and a base 110 with a base surface 115 mounted on a housing 120 . Both the guide surface 105 and the base surface 115 are perpendicular to each other and face away from the housing 120 . When the base surface 115 and the surface 200 of the workpiece 220 to be cut ( Figure 6 ) are engaged, the guide surface 105 extends across the surface of the cut material at the front position of the housing 120, so that the cutting member 300 that is in face-to-face contact with the guide surface 105 is guided during the cutting process of the workpiece 220.

[0085] The housing 120 houses a tape measure 150 which is drawn out from the rear end surface 125 of the housing 120 in a rearward direction away from the guide plate 100 . The free end 155 of the tape measure 150 is provided with a lip 160 which fits over an edge 260 of a workpiece. The free...

Abstract

A saw guide intended for guiding the blade of a saw during cutting of a workpiece (220). The saw guide (10) comprises: a housing (120) having a basal surface (115) and a guide surface (105) adapted to be positioned on a workpiece (220) to be cut, such that with the basal surface (115) engaging a surface (200) of the workpiece (220), the guide surface (105) extends across the surface to be cut at a forward position of the housing, such that a cutting member (300) in face to face contact with the guide surface (105) may be guided during cutting of the workpiece (220), and measuring means for measuring a position of the guide surface (105) with respect to a workpiece (220) such that, in use, the position of the guide surface (105) may be monitored by reference to said measuring means, during a cutting operation of the workpiece (220). The saw guide enables a cut to be made with continual reference to the measuring means.

Description

technical field [0001] The present invention relates to a guide for use with a hand saw that can be used to cut materials including wood, plastic and metal. Background technique [0002] It is known to use a guide to aid in the cutting of the material in order to be able to cut the material in a straight line. Non-expert workers often find this cutting operation particularly challenging due to the high degree of coordination of the angle and position of the saw blade relative to the material being cut, as well as the reciprocation of the saw blade between the first and second blade positions action. [0003] A simple auxiliary saw box can be used as a guide, especially when cutting wood, which is adapted to hold the material to be cut and at the same time provide guidance to the saw blade in the form of a slot. [0004] US 2003 / 0230180 (HINES) patent document discloses a guide that can be used with a cutting member with two angled members so that when one member comes into...
