1. Field of the Invention
The present invention relates to a magazine strip for use in a setting power tool and including a plurality of fastening elements and a carrier strip for carrying the fastening elements and formed of a plurality of strip segments each having a receptacle for a fastening element.
2. Description of the Prior Art
Magazine strips of the type described above are used, e.g., in hand-held setting or drive-in power tools which can drive fastening elements carried by the magazine strip into a workpiece.
U.S. Patent Publication US 2003/0075466 discloses a magazine strip for fastening elements having a plurality of strip segments which are formed as guide and damping sleeves and which are connected with each other so that they form a chain. The strip segments are connected with each other by webs which have, in a direction perpendicular to the strip plane, a smaller width than the guide and damping sleeves. The smaller width of the material perpendicular to the strip plane provides for a certain elasticity and, therefore, flexibility of the magazine strip between two adjacent strip segments.
The drawback of the known magazine strip consists in that in certain magazines that are used in setting or drive-in tools, the strip has a small sidewise mobility.
Accordingly, an object of the present invention is to provide a magazine strip with fastening elements having a high sidewise mobility.
This and other objects of the present invention, which will become apparent hereinafter, are achieved by providing, in the magazine strip, a plurality of pivot connections between respective adjacent strip segments for enabling a pivotal movement of the strip segments relative to each other, with pivot axes of the pivot connections extending coaxially with respective fastening elements (or their longitudinal axes).
The pivotal movement of the strip segments relative to each other about the pivot axes of the pivot connections provides for a high sidewise mobility of the magazine strip.
Advantageously, each fastening element connects two respective adjacent strip segments as chain elements so that each fastening element itself forms a pivot support axis. Further, forming magazine strip of a plurality of strip segments connected with each other by fastening elements, permits to produce a magazine strip of an arbitrary selected length.
Advantageously, each strip segment has a sleeve-shaped first section, a web-shaped second section projecting radially from the first section, and a third annular section arranged on the second section and a ring axis of which extends parallel to a cylinder axis of the first section and which axially lies outside of a radial projection of the first section. This formation of strip segments permits to easily produce them by the injection-molding technology.
The inventive multi-part carrier strip permits to achieve as good guide characteristics of the magazine strip as with a magazine strip formed as one-piece member when an annular fourth section is directly formed on an end of the first section remote from the third section, with the forth section having, at least in one region, a greater diameter than the first section. The greater diameter can be advantageously used for guiding the magazine strip in a magazine.
The guide characteristics of the magazine strip can be further improved when the third section has, in at least one region, a greater diameter than the first section.
The novel features of the present invention, which are considered as characteristic for the invention, are set forth in the appended claims. The invention itself, however, both as to its construction and its mode of operation, together with additional advantages and objects thereof, will be best understood from the following detailed description of preferred embodiment, when read with reference to the accompanying drawings.
