Abstract

A saw sheath is provided which allows a saw to be inserted easily and smoothly, which prevents the inserted saw from easily falling out or rattling in the sheath, and which can suppress scraping-off of the inner wall by the blade tip of the saw blade caught by the inner wall. The saw sheath (1) includes a flat sheath opening section (10) and a flat main sheath body (20), and a saw blade (31) is inserted into the main sheath body (20) via the sheath opening section (10). The sheath opening section (10) has an opening width that is wider at the entrance and becomes narrower with depth. A pair of guide rollers (11a) are provided at the entrance of the sheath opening section (10), on the respective sides in the width direction of the entrance, and a pair of grip penetration preventing sections (15) are provided behind the pair of guide rollers (11a). Certain spacing between the grip penetration preventing section (15) and the corresponding guide roller (11a) constitutes an elastic grip-fitting space (16).

Claims

1. A saw sheath including a flat sheath opening section and a flat main sheath body continuing from the sheath opening section, a saw blade being inserted, from a blade tip thereof, into the main sheath body through the sheath opening section, wherein the sheath opening section has an opening width that is wider at an entrance thereof and becomes narrower with depth, a pair of guide rollers for guiding the blade tip into the sheath opening section are provided at the entrance of the sheath opening section, on respective sides in a width direction of the entrance, a pair of grip penetration preventing sections for preventing further penetration of a saw grip are provided behind the pair of guide rollers, an elastic grip-fitting space for receiving and elastically fitting a part of the saw grip therein is secured between the grip penetration preventing section and the corresponding guide roller.

2. The saw sheath according to claim 1, wherein a pair of second guide rollers are provided deep in an interior of the sheath opening section, on respective sides perpendicular to the width direction of the interior, the second guide rollers guiding the saw blade entering toward the main sheath body such that the orientation of the saw blade coincides with a flatwise direction of the main sheath body.

3. The saw sheath according to claim 1, wherein a pair of third guide rollers for guiding the blade tip into the main sheath body are provided in front of the main sheath body, on the respective sides in the width direction of the sheath opening section.

4. The saw sheath according to claim 1, wherein the flat sheath opening section is made up of a split body consisting of a lower sheath opening part and an upper sheath opening part separably joined to each other, and the flat main sheath body has a front end portion sandwiched between the lower sheath opening part and the upper sheath opening part so as to be integrated with the sheath opening section.

5. The saw sheath according to claim 2, wherein a pair of third guide rollers for guiding the blade tip into the main sheath body are provided in front of the main sheath body, on the respective sides in the width direction of the sheath opening section.

6. The saw sheath according to claim 2, wherein the flat sheath opening section is made up of a split body consisting of a lower sheath opening part and an upper sheath opening part separably joined to each other, and the flat main sheath body has a front end portion sandwiched between the lower sheath opening part and the upper sheath opening part so as to be integrated with the sheath opening section.

7. The saw sheath according to claim 3, wherein the flat sheath opening section is made up of a split body consisting of a lower sheath opening part and an upper sheath opening part separably joined to each other, and the flat main sheath body has a front end portion sandwiched between the lower sheath opening part and the upper sheath opening part so as to be integrated with the sheath opening section.

8. The saw sheath according to claim 5, wherein the flat sheath opening section is made up of a split body consisting of a lower sheath opening part and an upper sheath opening part separably joined to each other, and the flat main sheath body has a front end portion sandwiched between the lower sheath opening part and the upper sheath opening part so as to be integrated with the sheath opening section.
