Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] 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.
[0003] 2. Description of the Prior Art
[0004] 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.
[0005] 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.
[0006] 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.
[0007] Accordingly, an object of the present invention is to
provide a magazine strip with fastening elements having a high
sidewise mobility.
SUMMARY OF THE INVENTION
[0008] 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).
[0009] 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.
[0010] 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.
[0011] 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.
[0012] 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.
[0013] 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.
[0014] 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.
BRIEF DESCRIPTION OF THE DRAWINGS:
[0015] The drawings show:
[0016] FIG. 1 a perspective view of two segments of the inventive
magazine strip;
[0017] FIG. 2 a side view of a magazine strip according to the
present invention for fastening elements; and
[0018] FIG. 3 plan view of the magazine strip shown in FIG. 1.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0019] A magazine strip 10 according to the present invention for
fastening elements, which is shown in FIGS. 1-3 completely or only
partially, has a carrier strip 11 formed of a plurality of
connected with each other, strip segments 12 is mounted.
Preferably, the strip segments 12 are formed of a plastic material
such as, e.g., polyethelene (PE), polypropylene (PP) or polystyrene
(PS). Each of the strip segments 12 has a receptacle formed as a
through-opening 13 in which a fastening element 20 is supported. As
particularly shown in FIG. 1, the strip segment 12 has a
sleeve-shaped first section 15, a web-shaped second section 16 that
projects radially from the first section 15, and an annular third
section 17 arranged on the second section 16. A ring axis R of the
third section 17 extends parallel to the cylinder axis Z of the
first section 15. The third section 17 is located axially outwardly
of a radial projection of the first section 15. That is why, with
the orientation shown in FIG. 1, the third section 17 is located
lower than the first section 15. The third section 17 has, at least
in one region, a greater diameter than the first section 15, and an
outer circumference of the third section 17 is used as a guide
profile. At an end of the first section 15 remote from the third
section 17, there is provided an annular fourth section 18 formed
directly on the first section 15. The fourth section 18 likewise
has a greater diameter, at least in one region, than the first
section 15, so that the outer circumference of the fourth section
18 also can be used as guide profile.
[0020] Adjacent strip segments 12 are pivotable relative to each
other, with pivot axes of the pivot connections 14 between adjacent
strip segments 12 extending coaxially with respect to corresponding
fastening elements 20. As it can particularly be seen in FIG. 1,
two respective adjacent strip segments 12 are connected by a
respective fastening element 20 as chain elements. The cylindrical
axis Z of the sleeve-shaped first section 15 of the strip segment
12 extends coaxially with the ring axis R of the third section 17
of an adjacent strip segment 12, so that a respective fastening
element 20 extends through both the first sleeve-shaped first
section 15 of one of the adjacent strip segments 12 and through the
annular section 17 of another of the adjacent strip segments 12,
connecting the two adjacent segments 12 with each other. The
longitudinal axis of the fastening element 20 likewise extends
coaxially with the cylindrical axis Z and ring axis R of respective
adjacent strip segments 12. As particularly shown in FIG. 3, the
inventive magazine strip 10 can pivot at pivot connections 14 about
respective fastening elements 20 over an angle .alpha. that can
amount maximum up to 170.degree..
[0021] Though the present invention was shown and described with
references to the preferred embodiment, such is merely illustrative
of the present invention and is not to be construed as a limitation
thereof and various modifications of the present invention will be
apparent to those skilled in the art. It is therefore not intended
that the present invention be limited to the disclosed embodiment
or details thereof, and the present invention includes all
variations and/or alternative embodiments within the spirit and
scope of the present invention as defined by the appended
claims.
