Description
[0001] This is a continuation of International Application
PCT/EP00/08112 with an international filing date of Aug. 19, 2000,
not published in English under PCT Article 21(2), and now
abandoned.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The invention relates to an arresting device for mounting
rails, supports, connecting parts and the like, comprising an
arresting plate having a cam for supporting it on a structural
member and a bracing section as well as at least one middle section
arranged between them and configured to receive a clamping member,
wherein at least one projection in the form of a pin is provided on
the bracing section and is formed as a point or tip projecting from
the bracing section.
[0004] 2. Description of the Related Art
[0005] For mounting rails, supports, connecting parts and the like,
several arresting plates, clamping brackets, claws and the like are
known which are either configured as universal clamps or are
configured so as to match the particular connecting situation. Such
an arresting device is comprised in general of an arresting plate
and a clamping element. The arresting plate comprises a cam for
supporting the arresting device on a structural member and a
bracing section, for example, for clamping a flange, and a saddle
formed between the cam and the bracing section. The clamping
element is usually received in the saddle.
[0006] With the conventional arresting devices, a high surface
pressure between the bracing section and the flange of a support is
achieved but when the clamping force decreases there is hardly any
resistance against sliding in the transverse direction. It has
therefore already been suggested to provide the clamping surface
with grooves or corrugations; however, experiments have shown that
even with this measure no significant improvement with regard to
the securing force in the transverse direction can be achieved. In
such arresting devices the resistance against sliding as a function
of the surface pressure cannot be precisely defined. The load
distribution depends on many unknown factors such as the friction
coefficient of the structural member in the thread, maintaining the
tightening torque and the like.
[0007] In U.S. Pat. No. 4,819,869 a device for attaching railroad
rails to wooden railroad ties is described. In this connection, a
plate is provided for supporting the rail on the railroad tie which
is secured by means of screw anchors on the wooden tie. In order to
secure the rail on the plate, holding-down elements are provided on
both sides of the rail which are supported on the plate by means of
a cam and on the foot of the rail by means of a bracing section.
The bracing section is provided with two steel points embedded in
the bracing section. The holding-down elements are fastened by
means of screw anchors which are threaded into sleeves in the
wooden tie. Such an arrangement is useful only to a limited
extent.
SUMMARY OF THE INVENTION
[0008] It is an object of the present invention to provide an
arresting device of the aforementioned kind which can be produced
in a simple way and which can be used universally for different
connecting arrangements.
[0009] In accordance with the present invention, this is achieved
in that the pin is comprised of a harder material than the
arresting plate and the pin is configured as a stud screw connected
by compression molding with the material of the bracing
section.
[0010] The pin can be secured in a threaded bore of the bracing
section. This stud screw can be provided at the end opposite the
point with a hexagon socket for receiving a matching tool. The pins
can be received either in a throughbore, in a blind bore, or a
stepped bore.
[0011] Especially expedient is an embodiment in which two pins are
arranged at a spacing to one another whose points at least
approximately project to the same extent or amount (distance) away
from the bracing section. In this way, an approximately uniform
penetration of the points and a uniform force distribution are
ensured.
[0012] At least one opening for penetration of a tie anchor should
be provided in the saddle. Expediently, this opening is formed as a
slotted hole. It is especially advantageous when three openings are
provided so that, depending on the rail or support to be mounted,
one or two tie anchors can be symmetrically employed, as desired.
In the case of arresting plates with three openings, it is also
possible to employ bracket-shaped clamping elements with different
leg spacing.
[0013] In order to ensure in a simple way an adjustment to the
flange shape and flange thickness, the arresting plate must be
configured to be positioned at different angles relative to the
clamping element. In order for the force introduction of the
clamping element onto the arresting plate to be uniformly
unaffected as much as possible independent of the position, it is
suggested that the saddle at its upper side is configured as a
concave depression or as a convex outwardly projecting bulge and
that in this depression or on this bulge a spherical cap or a
clamping strip with matching surface is positioned.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0038] In FIGS. 1 through 4 an arresting plate 1 is illustrated
which comprises a cam 6, a bracing section 10, and a middle section
in the form of a saddle 5 arranged therebetween. In the area of the
saddle 5, three slotted holes 2 are arranged whose longitudinal
axes extend parallel to one another. On the upper side of the
saddle 5 a concave depression 4 is provided. The underside of the
arresting plate 1 is arc-shaped or curved. From the slotted hole 2
to the arc, a conically widened portion 3 is provided. On the side
of the saddle 5 facing the cam 6 the arresting plate 1 is provided
with a recess 11. At the lower end of the cam 6 a bearing surface
6' is provided against which the structural member to be connected
rests. Laterally adjacent to the bearing surface 6' projections 7
are provided so that a structural member positioned on the bearing
surface 6' is laterally engaged. In the bracing section 10 pins 8
are provided which have points or tips 9. They project away from
the underside of the bracing section 10.
[0039] FIGS. 5 and 6 show an arresting plate 21 which has only a
single slotted hole 22. On the top side of a saddle 25 a concave
depression 24 is provided. The saddle 25 is provided with a recess
20 in the direction toward the cam 26. The underside of the cam 26
is configured as a bearing surface 26' with projections 27 adjacent
to the bearing surface 26'. On the opposite end of the arresting
plate 21 a bracing section 30 is provided in which two pins 28 with
points 29 formed thereon are secured.
[0040] In the embodiments of FIGS. 1 through 6, the pins 8 or 28
are formed as stud screws with a hexagon socket 40 on the end of
the stud screw remote from the tip 9 or 29. This stud screw is
secured in a threaded bore 42 in the bracing section 10, 30,
respectively.
[0041] FIGS. 7 through 10 show that the arresting device comprised
of the arresting plate 1 and a clamping member in the form of a
clamping bracket 13 is suitable for fastening different supports
and flanges. The clamping member or clamping bracket 13 is
illustrated as an individual part in FIG. 11. This clamping bracket
13 has two parallel extending legs 14 and 14' wherein each one of
these legs 14, 14' is provided with a threaded section 15, 15'. The
spacing S between the legs 14, 14' is determined by the respective
size or spacing of the slotted holes 2 in the arresting plate 1.
Between the legs 14, 14', a rail 18 is received which is to be
connected with a support 12 (FIG. 7) or 12* (FIG. 8). As can be
seen clearly in FIGS. 7 through 9, the supports 12 and 12* have
different thickness. With the aid of the arresting plate 1,
however, the connection can be realized independent of the
respective thickness of the support 12, 12* without requiring any
changes, because, on the one hand, the position of the arresting
plate 1, relative to the clamping bracket 13, is variable and, on
the other hand, there is always a suitable contact of the cam 6 on
the rail 18 as a result of the contour of the bearing surface 6'.
Moreover, the point 9 of the pin 8 can penetrate into the surface
of the supports 12 or 12* in both positions of the arresting plate
1.
[0042] FIGS. 9 and 10 show the arresting plate 1 in connection with
a clamped rail flange as an example, wherein in FIG. 9 a straight
flange 19 and in FIG. 10 a slanted flange 19* are illustrated. In
FIGS. 7 through 10, a spherical cap 17 is provided as an
intermediate member for providing a suitable supporting action for
a clamping nut 16 threaded onto the threaded section 15 of the
clamping member in the form of a tie anchor. The spherical surface
of the cap 17 always ensures a suitable contact and force
introduction into the saddle 5 of the arresting plate 1.
[0043] The spherical cap 17 is illustrated in FIG. 12 in three
different views wherein FIG. 12a shows a plan view, FIG. 12b shows
a section, and FIG. 12c a side view of the spherical cap.
[0044] Instead of employing individual spherical caps, it is also
possible to employ a clamping strip 37 as an intermediate member,
as illustrated in FIG. 13. In this connection, FIG. 13a shows a
plan view onto the clamping strip 37 having two slotted holes 38.
As illustrated in FIG. 13b, the cross-section of the clamping strip
37 is of such a configuration that the top side of the clamping
strip 37 is planar and the underside is shaped like a cylinder
section. This means that the underside has a bulge or convexity 39.
FIG. 13c shows a longitudinal section of the clamping strip 37 with
the two slotted holes 38. The slotted holes 38 enable receiving of
clamping means at different spacings, i.e., even clamping brackets
with different spacings of the parallel legs can be received in the
slotted holes 38; alternatively, round holes can also be
provided.
[0045] FIG. 14 shows a plan view onto an arresting plate 31 which
correspond substantially to the one illustrated in FIG. 1.
Accordingly, the cam 6 as well as the bracing section 33 with the
pins 8 arranged therein are identical. The arresting plate 31 has a
cylinder section-shaped depression 34 in which three parallel
slotted holes 36 are arranged. In FIG. 14 several positions of
clamping elements are illustrated in an exemplary fashion, wherein
these are the legs 14, 14', 14*, 14** of clamping brackets. In this
connection, not only a symmetrical arrangement of the legs 14,14'
or 14* is possible, but also an asymmetrical arrangement of legs
14* and 14**. With such a configuration of the arresting plate 31 a
plurality of different leg spacings can be realized wherein two
examples are illustrated in FIG. 14, i.e., a spacing S1 between the
legs 14 and 14', and a spacing S2 between the legs 14* which are
positioned laterally adjacent to the arresting plate 31,
respectively. For such a leg spacing it is however required to
provide a clamping strip 37 of a corresponding length by which the
force of the clamping elements can be transmitted onto the
arresting plate 31.
[0046] FIG. 15 shows a section of an arresting device which is
fastened by means of a clamping member in the form of a hammer head
screw 23 on the profiled rail 18 and clamps a support 12'.
Otherwise, this embodiment of FIG. 15 corresponds to that of FIG. 8
so that the same reference numerals are employed for the same
parts.
[0047] FIG. 16 shows different embodiments of pins and points or
tips. As already illustrated in the above described Figures, the
bracing section 10 can be provided with threaded bores 42 into
which the threaded pins 8 in the form of stud screws are threaded.
On the end which projects downwardly from the bracing section 10,
the pin 8 is provided with the tip or point 9 which in the present
case has a small flattened area. The pin 8 is comprised of a hard
or hardened material so that it is capable of penetrating into the
softer material of the object to be clamped. At the end remote from
the point 9, the pin 8 has a hexagon socket 40 for use in
connection with a matching tool.
[0048] The pin 44, as illustrated in the lower area of FIG. 16, can
have a point 29 which is completely conical. As an alternative
thereto, it is also possible to configure the front end as a
spherical section as illustrated in the example of point 49. In the
upper area of FIG. 16, it is also illustrated that in the bracing
section 10 a blind bore 43 is arranged in which the pin 44* can be
received. This pin 44* can be fastened in the bracing section by
compression-molding or pressing with the material of the bracing
section 10. There is also the possibility of configuring the bore
as a stepped bore 45 into which the pin 44* is then inserted.
[0049] FIG. 17 shows a plan view onto an arresting plate 61 whose
section is illustrated in FIG. 18 and whose side view is
illustrated in FIG. 19. This arresting plate 61 has a depression 64
with a slotted hole 62 wherein the depression 64 is arranged
between a saddle 65 and a bracing section 70. The saddle is
provided in the direction toward the cam 66 with a recess 60. In
the bracing section 70 the pins 8 are provided in threaded bores 42
in the same way as described in connection with FIG. 1. At the
lower end of the cam 66, projections 67 extending downwardly are
arranged on both sides; adjacent thereto, a step 68 is provided on
the inner side of the projections, respectively, i.e., the steps 68
are facing one another. Between these steps 68 a first bearing
surface 66' is formed which has a length L1 corresponding to the
distance between the steps 68. In contrast, the distance L2 between
the projections 67 is greater. Adjacent to the projections 67,
partial surfaces of a second bearing surface 66* are formed by the
steps 68. The configuration according to FIGS. 17 through 19 has
the advantage that the arresting plate 61 can be used without
changes for different profile widths or the like.
[0050] While specific embodiments of the invention have been shown
and described in detail to illustrate the inventive principles, it
will be understood that the invention may be embodied otherwise
without departing from such principles.
