Abstract

A driving tool may include a driven member holding mechanism configured to hold the driven member at a driving position inside a driver guide until a driver drives the driven member.

First claim

What is claimed is:

1. A driving tool comprising:
a tool body;
a driver configured to drive a driven member;
a driver guide configured to guide the driver together with the driven member, the driver guide being movable with respect to the tool body; and

a driven member holding mechanism configured to hold the driven member at a driving position inside the driver guide until the driven member is driven by the driver and such holding of the driven member occurring independently of a movement of the driver guide with respect to the tool body, wherein:
the driven member holding mechanism comprises an internally exposed member exposed inside the driver guide;
the internally exposed member is a separate member from the driver guide and does not move in conjunction with the movement of the driver guide with respect to the tool body;
the internally exposed member includes a pressing surface against which the driven member is pressed by a feeding force that feeds the driven member toward the driving position; and
the driven member pressed against the pressing surface is held at the driving position until the driven member is driven by the driver and such holding of the driven member occurring independently of the movement of the driver guide with respect to the tool body.

2. The driving tool according to claim 1 , wherein the driver guide has an opening through which the pressing surface is exposed to inside of the driver guide.

3. The driving tool according to claim 1 , further comprising:
a plurality of driven members bundled together by a bundle resin strip, so that outer circumferential surfaces of the driven members are covered by the bundle resin strip; and
wherein the driven member is pressed against the pressing surface via the bundle resin strip.

4. A driving comprising:
a tool body;
a driver configured to drive a driven member;
a driver guide configured to guide the driver together with the driven member, the driver guide being movable with respect to the tool body; and

a driven member holding mechanism configured to hold the driven member at a driving position inside the driver guide until the driven member is driven by the driver and such holding of the driven member occurring independently of a movement of the driver guide with respect to tool body, wherein:
the driven member holding mechanism comprises an engaging mechanism having an engaging member which is movable into and out of a driving passage defined in the driver guide;
when the driver is moved to drive the driven member, the engaging member is positioned outside of the driving passage; and
when the driver is not moved to drive the driven member, the engaging member is positioned within the driving passage to engage the driven member.

5. The driving tool according to claim 4 , further comprising:
a plurality of driven members bundled together by a bundle resin strip, so that outer circumferential surfaces of the driven members are covered by the bundle resin strip; and
wherein the engaging member comprises a claw member configured to engage the bundle resin strip.

6. A driving tool comprising:
a tool body;
a driver configured to drive a driven member;
a driver guide configured to guide the driver together with the driven member, the driver guide being movable with respect to the tool body; and

a driven member holding mechanism configured to hold the driven member at a driving position inside the driver guide until the driven member is driven by the driver and such holding of the driven member occurring independently of a movement of the driver guide with respect to the tool body, wherein:
the driver guide has an end portion configured as a contact top for contacting an object into which the driven member is driven; and
the driver guide moves with respect to the tool body as the contact top is pressed against the object.

7. The driving tool according to claim 6 , wherein;
the driving tool is a combustion-type driving tool having a combustion chamber provided in the tool body;
the combustion chamber closes in response to a pressing movement of the contact top against the object.

8. A driving tool comprising:
a tool body;
a magazine connected to the tool body, wherein a plurality of driven members bundled together by a bundle resin strip are loaded in the magazine;
a driver configured to drive one by one the driven members of the bundle resin strip;
a driver guide configured to guide the driver together with a driven member of the plurality of driven members that is to be driven, the driver guide being movable with respect to the tool body; and
a driven member holding mechanism configured to hold the driven member to be driven at a driving position inside the driver guide until the driven member is driven by the driver,
wherein the driven member holding mechanism includes an internally exposed member fixed in position relative to the tool body, at least a part of the internally exposed member being exposed to an inside of the driver guide.
