Claims
- 1. A nailing machine comprising:
- a cylinder housing defined in surrounding relation to a piston provided with a driver for driving a nail, a cylinder which slidably houses said piston, and a head valve for controlling supply and exhaust of compressed fluid into and from said cylinder; and
- a nailing machine body including a grip, a nail magazine, a nail feed means for feeding a nail from said nail magazine to a nail injection portion for receiving a nail fed by said feed means from said magazine and driving out such nail, a bumper means fixedly mounted with respect to said nailing machine body and arranged to collide with a lower surface of said piston for absorbing impact of said piston at the time of nailing, said cylinder housing being supported on said nailing machine body so as to be movable with respect thereto along an axis in a nail-driving direction so that said piston within said cylinder can be driven downward by said compressed fluid so that said driver drives a nail, and a trigger valve being manually operated for remote controlling a head valve and a compressed fluid intake for receiving a compressed fluid from a compressed fluid supply source, in which said nailing machine further comprises:
- a first movable communicating tube for connecting said trigger valve to an end of said head valve of said cylinder housing so as to give an nail-driving signal to said head valve; and
- a second movable communicating tube for connecting said compressed fluid intake with the other end of said head valve.
- 2. A nailing machine as in claim 1 wherein said nailing machine body integrally further includes a columned guide surface at an upper portion on said nail injection portion, and said cylinder housing integrally further includes a cylindrical guide surface for housing said columned guide surface at a lower portion of said cylinder housing, wherein said cylinder housing is supported to said nailing machine body by said columned guide surface and said cylindrical guide surface in such a manner that said cylinder housing is movable along the axis in the nail-driving direction.
- 3. A nailing machine as in claim 2 further comprising a positioning means for urging said nailing machine body and said cylinder housing into a predetermined relative position.
- 4. A nailing machine as in claim 3 wherein said positioning means is a compression spring and said cylinder housing moves relative to said nailing machine body along the axis in the nail-driving direction against the action of said compression spring.
- 5. A nailing machine as in claim 1 wherein said second movable communicating tube is flexible.
- 6. A nailing machine as in claim 5 wherein a first end of said first movable communicating tube is slidably disposed in a first air path running parallel with the axis in the nail-driving direction.
- 7. A nailing machine comprising a body and a grip member wherein:
- said body comprises:
- a cylinder having an opening portion at one end,
- a piston integrally provided with a driver for driving a nail and slidably housed in said cylinder,
- a head valve for controlling the opening and closing of said opening portion of said cylinder, and
- a cylindrical housing defined in surrounding relation to said cylinder, said piston and said head valve; and
- said grip member comprises:
- a nose member having a nail outlet to which a nail is disposed for being driven and through which said driver for driving the nail is slidably moved,
- a bumper means fixedly coupled to an upper end of said nose member for engaging said piston, and
- a guide surface formed as an inner peripheral surface of a cylinder housing surrounding said cylindrical housing of said body, said nose member being fixed with respect to said guide surface,
- wherein an outer peripheral surface of said cylindrical housing is movably supported along an axis parallel to the nail driving direction by said guide surface, so that said body is supported by said grip member.
- 8. A nailing machine as in claim 7 further comprising an annular communication air chamber provided between said guide surface of said grip member and said outer peripheral surface of said housing and a difference in effective area defined between an upper and a lower surface of said air chamber, so that said body is urged to a nail-driving side by an air compression at all times.
- 9. A nailing machine as in claim 8 wherein:
- said grip member further comprises a trigger valve for controlling the supplying and the exhausting of a compressed air for operating said head valve, said trigger valve being manually operable, and
- said annular chamber is disposed on an air path for communicating said trigger valve and said head valve.
- 10. A nailing machine as in claim 7 wherein:
- said body further comprises an air chamber defined on an outer peripheral surface of said cylinder for accumulating a pressure of a compressed air for driving a piston, and
- said grip member further comprises a hollow portion connected to a compressed air supply source and a trigger valve manually operable for supplying and exhausting said compressed air for operating said head valve,
- in which said nailing machine further comprises an air path defined by slide seals between said guide surface of said cylindrical housing of said body and an outer peripheral surface of said housing so as to connect said trigger valve and said hollow portion to said head valve and said chamber.
- 11. A nailing machine as in claim 10 wherein:
- two annular recess portions defined by said slide seals along an axis parallel to a nail-driving direction are provided within said guide surface of said grip member so as to connect with said hollow portion and with said trigger valve, respectively,
- two opening portion opposed to said two annular recess portions and isolated from each other in the axial direction are provided within said outer peripheral surface of said body so as to connect said recess portions with said head valve and with said chamber.
