Agricultural Cooperative Society Ltd. - Inventors: Gilad Rafaeli - Web page: https://patentgrep.com/patent/US7407073B2 ## CPC - B25C 1/02: operated by manual power - B25C 1/00: Hand-held nailing tools (hammers per se B25D; nailing machines B27F7/02); Nail feeding devices - B25C: HAND-HELD NAILING OR STAPLING TOOLS; MANUALLY OPERATED PORTABLE STAPLING TOOLS (for shoemaking A43D) ## Abstract A nail-guiding device comprising a sleeve having a linear passage therethrough, the linear passage having a first end at least partially covered by a flexible membrane with an opening, the membrane operative to engage and hold the nail, and a piston slideably engaged in the linear passage and operative to transfer the impact of the driver to the nail in a drive-in operation. ## Claims ### Claim 1 A nail-guiding device that assists in the proper guiding of a nail with respect to a surface and with respect to a driver, comprising: a. a body including abutment features for abutment against the surface and a sleeve defining a linear passage; b. a flexible membrane deployed so as to at least partially overlap an end of said linear passage, said flexible membrane including an opening for engaging the shaft of a nail; and c. a piston slideably engaged in said linear passage and operative to transfer the impact of the driver to the nail in a drive-in operation, wherein said membrane is sufficiently flexible to allow insertion via said opening of the head of a nail having dimensions greater than dimensions of said opening, and wherein said membrane is deployed relative to said abutment features such that when said abutment features are brought into abutment with the surface, at least a portion of said flexible membrane adjacent to said opening is spaced away from the surface, thereby holding and guiding the nail throughout said drive-in operation. ### Claim 2 (depends on 1) The device of claim 1, wherein said piston includes a first end operatively associated with said linear passage first end, the piston first end including a concave surface suitable for centering a head of said nail. ### Claim 3 (depends on 1) The device of claim 1, wherein said membrane is fixedly attached to said body. ### Claim 4 (depends on 3) The device of claim 3, wherein said fixed attachment is effected by gluing. ### Claim 5 (depends on 3) The device of claim 3, wherein said fixed attachment is effected by injection molding. ### Claim 6 (depends on 1) The device of claim 1, wherein said flexible membrane is made of rubber. ### Claim 7 (depends on 1) The device of claim 1, wherein said opening is round. ### Claim 8 (depends on 1) The device of claim 1, wherein said body includes an accessory storage compartment. ### Claim 9 (depends on 1) The device of claim 1, wherein said body includes a level indicator. ### Claim 10 A hand tool for assisting the driving of a nail into a surface at a drive-in location, comprising: a. a guiding mechanism having abutment features for abutting the surface and a flexible membrane nail holding and guiding element, said flexible membrane nail holding and guiding element including an opening for engaging the shaft of a nail; and b. a driving element slideably engaged in said guiding mechanism and operative to drive the nail into the substrate at the drive-in location, wherein said membrane nail holding and guiding element is sufficiently flexible to allow insertion via said opening of the head of a nail having dimensions greater than dimensions of said opening, and wherein said membrane nail holding and guiding element is deployed relative to said abutment features such that, when said abutment features are brought into abutment with the surface, at least a portion of said flexible membrane nail holding and guiding element adjacent to said opening is spaced away from the surface, thereby holding and guiding the nail throughout said drive-in operation. ### Claim 11 (depends on 10) The hand tool of claim 10, wherein said membrane is fixedly attached to said guiding mechanism. ### Claim 12 (depends on 10) The hand tool of claim 10, wherein said membrane is made of rubber. ### Claim 13 (depends on 10) The hand tool of claim 10, wherein said opening is round. ### Claim 14 (depends on 10) The hand tool of claim 10, wherein said opening is slit. ### Claim 15 A method for driving a nail into a surface comprising the steps of: a. providing a body including abutment features for abutment against the surface and a sleeve defining a linear passage; b. providing a flexible membrane deployed so as to at least partially overlap an end of said linear passage, said flexible membrane including an opening for engaging the shaft of a nail; c. providing a piston slideably engaged in said linear passage and operative to transfer the impact of the driver to the nail in a drive-in operation; d. inserting the head of a nail via said opening, the head of the nail having dimensions greater than dimensions of said opening and passing through said opening by flexing of said membrane; e. deploying said abutment features in abutment with the surface while at least a portion of said flexible membrane adjacent to said opening remains spaced away from the surface, thereby holding and guiding the nail; and f. impacting said piston so that the nail is driven into the surface while being guided by said flexible membrane. ### Claim 16 (depends on 15) The method of claim 15, wherein said piston includes a concave end, and wherein said step of inserting the head of the nail includes engaging the head of the nail with said concave end. ### Claim 17 (depends on 15) The method of claim 15, wherein said flexible membrane is a fixedly attached to said body.
