Attaching device for attaching stopping or lashing means
Abstract
Disclosed is an attaching device for attaching stopping or
lashing means to objects that are to be transported or tied down,
comprising a fixing element (1), an attaching element (16), and a
connecting element (15) which is rotatably mounted on a socket (4)
wrapped around the fixing element (1) and connects the attaching
element (16) to the fixing element (1). The connecting element (15)
leans against ring flanges (6, 7) placed at the ends of the socket
(4) via series of rolling bodies (12, 13) so as to allow said
connecting element (15) to rotate without jerking and make it
sufficiently tilt-proof.

Description
TECHNICAL FIELD
[0001] The invention relates to an attachment device for attaching
slinging or lashing means to articles which are to be transported
or lashed, having a fastening element which serves for fastening
the same on the respective article and is formed by a bolt, having
an attachment element for the slinging or lashing means, and having
a connecting element which connects the fastening element to the
attachment element, is mounted, such that it can be rotated about
the longitudinal axis of the fastening element, on a two-part
bushing enclosing the fastening element over part of its length,
and has its axial position on the bushing secured by annular
flanges arranged at opposite ends of the bushing.
PRIOR ART
[0002] An attachment element of the abovementioned type is known
from DE 10013845 A1. In the case of the known device, the
connecting element is mounted with a sliding fit on a bushing which
comprises two parts, of which the facing end surfaces butt against
one another. The sliding mounting usually satisfies the
requirements which are to be fulfilled. However, problems may arise
if heavy articles are to be turned in addition to being raised. In
order to increase the rotatability of a connecting element, it is
known from DE 8406130.8 U1 to arrange, between the fastening
element and the connecting element, a series of rolling-contact
bodies with the rolling-contact bodies comprising balls which have
to be introduced into their guide path from the outside of the
connecting element with comparatively high outlay. The use of just
one series of rolling-contact bodies places narrow limits on the
tilting resistance of the connecting element in relation to the
fastening element of this second known device.
DESCRIPTION OF THE INVENTION
[0003] The object of the invention, in the case of an attachment
device of the type in question, is to increase the relative
movement capability between the fastening element and the
connecting element by replacing the sliding mounting with an
easy-to-install rolling-contact mounting, a high level of tilting
resistance of the connecting element being desired at the same
time. This object is achieved, in the case of an attachment device
of generic type, in that the connecting element is supported on the
bushing, in the region of the annular flanges of the bushing, via a
series of rolling-contact bodies in each case.
[0004] The attachment device according to the invention is quick
and easy to assemble. The level of tilting resistance of its
connecting element is high, on account of the use of two series of
rolling-contact bodies which are spaced apart from one another by
the greatest possible distance, and the rotatability of the
connecting element leaves nothing to be desired, even for raising
heavy loads.
[0005] Further features and details of the invention can also be
gathered from the subclaims and the following description of two
embodiments of the invention which are illustrated in the attached
drawing.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] In the drawings:
[0007] FIG. 1 shows the front view of a first attachment
device,
[0008] FIG. 2 shows a section along line II-II in FIG. 1,
[0009] FIG. 3 shows, partly in section, the side view of a second
attachment device, and
[0010] FIG. 4 shows a plan view of the attachment device according
to FIG. 3 with the attachment element swung over the fastening
element.
[0011] In FIGS. 1 and 2, 1 is a fastening element which is formed
by a bolt and on which a bushing 4 comprising two parts 2 and 3 is
mounted. The two parts 2 and 3 overlap in the central region of the
bushing 4 and are connected to one another by a press fit in the
overlapping zone. A spring ring 5 secures the position of the
bushing 4 on the fastening element 1.
[0012] At its opposite ends, the bushing 4 has two annular flanges
6 and 7, which merge into the cylindrical part of the bushing 4 via
conical surfaces 8 and 9. In the region of the conical surfaces 8
and 9, two series of rolling-contact bodies 12 and 13 are arranged
between the bushing 4 and a connecting element 10, which connects
the fastening element to an annular attachment element 11, these
series of rolling-contact bodies, together with the bushing 4 and
the connecting element 10, forming angular roller bearings. The
series of rolling-contact bearings 12 and 13 are easy to install in
that, first of all, the rolling-contact bodies of the series of
rolling-contact bodies 13 are positioned on the conical surface 9,
the connecting element 10 is then pushed over the bottom part 3 of
the bushing 4, the rolling-contact bodies of the series of
rolling-contact bodies 12, thereafter, are lined up in a row on the
running surface provided on the connecting element 10, and,
following this, the top part 2 and the bottom part 3 of the bushing
are pressed together. In a final installation step, the fastening
element 1 is forced into the bushing 4 until the spring ring 5
latches into a groove 14 in the interior of the bushing 4.
[0013] In the case of the attachment device according to FIGS. 3
and 4, in which use is made of the same designations for parts
which correspond to the parts illustrated in FIGS. 1 and 2, the
connecting element 15 is assembled with the fastening element 1 in
the same way as has been described above, so that, in this respect,
you can refer to what has already been said. The difference between
the second embodiment and the first embodiment described above is
that the attachment element 16 of the second embodiment is
connected in a releasable manner to the connecting element 15. For
this purpose, the connecting element 15 is provided with a fork
head 17 which has an introduction gap 18 which can be bridged by a
transverse bolt 19. The introduction gap 18, which has an inside
width W.sub.1, is adjoined by an eyelet 20 with an inside width
W.sub.2, which corresponds at least to 1.5 times the inside width
W.sub.1 of the introduction gap 18. Using a connecting element 15
with a fork head 17 makes it possible to combine the connecting
element 15 with different types of attachment element. It is
advantageous here to use attachment elements which, like the
attachment element 16 illustrated in FIGS. 3 and 4 and formed by a
suspension member, are provided with a flattened zone 21, of which
the thickness a is smaller than the inside width W.sub.1 of the
introduction gap 18.
