Un dispositif d'enfoncement d'éléments de fixation, destiné à l'enfoncement d'éléments de fixation tels que des clous, des vis etc., comprend un organe de réception et de guidage (15) d'éléments de fixation, recevant ces éléments de fixation (17) dans une position lui permettant d'agir de concert avec un organe d'enfoncement (14) d'éléments de fixation et guidant les éléments de fixation vers l'emplacement d'enfoncement prévu; un magasin d'éléments de fixation (19) possèdant un canal de guidage (22) d'éléments de fixation servant à guider ces éléments disposés côte à côte vers l'organe de réception et de guidage (15) d'éléments de fixation; un organe d'avance (29, 48) servant à faire avancer les éléments de fixation arrivant du magasin (19) vers l'organe de réception et de guidage d'éléments de fixation. L'organe d'avance (29, 48) comprend un organe bifurqué (29) conçu pour agir de concert avec le canal de guidage dans le magasin (19). L'organe bifurqué (29) possède un évidement ou sillon allongé (33) de chaque côté duquel sont disposées les dents ou branches (31, 32) de l'organe bifurqué, et la largeur du sillon est réglée pour recevoir un élément de fixation (17) à la fois. Dans le but de faire avancer les éléments de fixation un à la fois, l'organe bifurqué (29) peut pivoter vers l'avant et vers l'arrière depuis une position de réception d'éléments de fixation, dans laquelle le sillon (33) est dirigé en biais vers le magasin (19) et l'embouchure du sillon s'étend au moins sur toute la largeur du canal de guidage, en passant par une position intermédiaire, dans laquelle le sillon s'étend transversalement sur le canal de guidage (22), jusqu'à et au delà d'une position dans laquelle le sillon (33) s'étend en biais vers l'organe de réception et de guidage (15) d'éléments de fixation, et l'embouchure du sillon s'étend au moins sur toute la largeur du canal de guidage. Les bords définissant l'embouchure du sillon sont formés par les extrémités extérieures des dents ou branches (31, 32) de l'organe bifurqué, et le

A fastening tool (10) including a magazine (50) securely and releasably retained on the fastening tool by a cam (80) mounted on one of the fastening tool and the magazine. In a single rotary motion, the cam wedges together a housing member (24) of the fastening tool and a housing member (56) of the magazine, while simultaneously rotating cam lobes (84, 86) into respective chambers (62, 64) formed on the fastening tool and the magazine. The cam rotation and magazine retention system is accomplished without tools.

A concrete nailer (10) and method of use. The method of using a concrete nailer to nail a channel (44) to concrete (50), the channel having a U-shape of walls (48) arranged vertically and a base (46) connecting the walls, comprising the steps of: providing a cutout (28) in a bottom portion (26) of a magazine (24) of the nailer; positioning a nose (32) of the concrete nailer above the channel so that the cutout clears at least one wall of the channel; engaging the base of the channel with a contact trip (30) of the concrete nailer oriented perpendicularly to the base of the channel while the cutout still clears the wall; then pressing the contact trip against the base of the channel so that the contact trip is fully actuated; and firing a nail through the base of the channel and into the concrete.
摘要:
A device is provided to apply fastening means (C) each provided at least with one almost flat head (H) having a central pass through hole (P) were two opposed sides (S) of said head have respective protrusions (J) at least approximately perpendicular in respect to the head (H) and forming shoulders (S).The remaining opposed sides of the head have respective tongues (L) jutting out of the head (H). Said device (1) comprises a first magazine (3) for nails (N) each assigned to block a fastening means (C) and it comprises a shooting means (5) assigned to shoot the nails (N) in a shooting direction for blocking the respective fastening means (C) through said hole (P). Said device (1) comprises a second magazine (9) having slide guide means (11) assigned house in a sliding manner a set of fastening means (C) with the tongues (L) oriented in the forward sliding direction (A) and the shoulders (S) being oriented transversally and toward the sliding direction provided to the fastening means (C) by pushing means (13) of the second magazine (9) towards an outlet end (15) of the second magazine (9). Said outlet end (15) has a pair of jaw means (17) hinged to respective first rotation pins (23) perpendicular oriented in respect to said sliding direction (A), said jaw means (17) are mutually faced and their front portions, in respect to the sliding direction (A), are elastically and mutually approached by means of respective elastic elements (21). Said front portions of the jaw means (17) fully protrude from the second store (9) toward said sliding direction (A), each of said jaw means (17) has at least a tooth (19) shaped in form of shoulder oriented towards the second magazine (9) and said tooth (19) is assigned to elastically match at least with a shoulder (S) of a fastening means (C) interposed between the jaw means (17). Said teeth (19) elastically and detachably hold the fastening means (C) in a position of alignment of the respective pass through hole (P) with the shooting direction of the shooting means (5).

摘要:
A fastener driving tool (12) with an improved nose chamber guide member (12) is provided for driving fasteners (14) of at least two different lengths. Multiple fasteners in a magazine are guided toward a driving bore (20) to be driven by a driver blade (22). A nosepiece (24) defines a passageway of the fasteners (14). The guide member (12) is operatively connected to the nosepiece (24) and is configured for transitioning between a first position and a second position relative to the nosepiece (24) in a direction (40) transverse to an operational flow direction of the fasteners (14). In the first position, the guide member (12) is disposed to align with the driving bore (20) for allowing driving of the fasteners (14) having a first length. In the second position, the guide member (12) is disposed out of alignment with respect to the driving bore (20) for allowing driving of the fasteners (14) having a second length, which is longer than the first length.
摘要:
A magazine includes a nail guide surface and a movable guide wall. The nail guide surface is linear and continuous to a nail introducing opening and has a shoulder for supporting the nail heads of a connected nail assembly. The movable guide wall is confronted with the nail guide surface. In the magazine, a plurality of connected nail assemblies are loaded and placed in side-by-side relation, while being in contact with each other, between the nail guide surface and the movable guide wall. The plurality of connected nail assemblies are pressed against the guide surface of the magazine by means of a pressing members provided on the movable guide wall. The movable guide wall is turned, for opening and closing, between a position being confronted with the nail guide surface of the magazine and a position at which the nail guide surface is opened.
