Detailed description
[0008] Next the cup device 1 for supporting a headed lifting stud 2 in a concrete product
3 and some embodiments and variants of the cup device 1 will be described in greater
detail.
[0009] The cup device 1 comprises a cup member 4 configured to be cast into the concrete
product 3 so that an inner surface 5 of an open top space 6 of the cup member 4 permanently
or temporarily forms a part of an outer surface 7 of the concrete product 3 and so
that a headed lifting stud 2 to be cast into the concrete product 3, such as into
a recess formed in the outer surface 7 of the concrete product 3, projects through
an opening 9 in the cup member 4 from concrete of the concrete product 3 into the
open top space 6 of the cup member 4. Permanently means in this connection that the
cup member 4 will be left in a building structure (not illustrated in the figures)
and temporarily means in this connection that the cup member will be removed for example
after that the concrete product has been produced by casting or after that the concrete
product has been lifted into its mounting position in a building structure.
[0010] The cup device 1 comprises a detachable attachable support member 8 configured for
keeping the headed lifting stud 2 in position with respect to the inner surface 5
of the open top space 6 of the cup member 4, wherein the detachable attachable support
member 8 is detachable attachable to the cup member 4 by means of first connection
means 12 and detachable attachable to the headed lifting stud 2 by means of second
connection means 13,
[0011] The detachable attachable support member 8 covering the open top space 6 of the cup
member 4 only partly. This provides for the advantage that the position of the headed
lifting stud 2 with respect to the inner surface 5 of the open top space 6 of the
cup member 4 is visible and can be corrected prior hardening of the concrete of the
concrete product 3 into which the headed lifting stud 2 is casted. This promotes safety
when lifting the concrete product 3 from the headed lifting stud 2 projecting from
the outer surface 7 of the concrete product 3 in recesses in the outer surface 7 of
the concrete product 3.
[0012] The cup member 4 functions also as a mold for forming a recess (not marked with a
reference numeral) in the outer surface 7 of the concrete product 3 so that the headed
lifting stud 2 projects from concrete of the concrete product 3 into the recess, but
not out of the recess.
[0013] The inner surface 5 of the cup member 4 can, as illustrated in the figures, be an
at least partly spherical inner surface so that the at least partly spherical inner
surface is configured to symmetrically surround the headed lifting stud 2.
[0014] The inner surface 5 of the cup member 4 can, as illustrated in the figures, have
at least partly the shape of a spherical segment so that the inner surface 5 of the
cup member 4 is configured to symmetrically surround the headed lifting stud 2.

[0016] The detachable attachable support member 8 covers preferably, but not necessarily,
the open top space 6 of the cup member 4 only partly by forming at least one sight
opening 10 between the inner surface 5 of the cup member 4 and the detachable attachable
support member 8, as in the embodiments illustrated in the figures. Alternatively
or additionally, the detachable attachable support member 8 can cover the open top
space 6 of the cup member 4 only partly by having at least one sight opening 10 formed
in the detachable attachable support member 8.
[0017] The cup device 1 can comprise a detachable attachable lid member 11 configure to
fully close the open top space 6 of the cup member 4 so that the detachable attachable
support member 8 is between the detachable attachable lid member 11 and the inner
surface 5 of the cup, when the detachable attachable support member 8 is detachable
attached to the cup member 4 by means of said first connection means 12 and detachable
attached to the headed lifting stud 2 by means of said second connection means 13.
Alternatively or additionally, the cup device 1 can comprise a detachable attachable
lid member 11 configured to fully close the open top space 6 of the cup member 4,
when the detachable attachable support member 8 is removed Both alternatives provide

the casting mold (not shown in the figures) supported by the lid members 11 on the
bottom (not shown in the figures) of the casting mold so that the headed lifting studs
2 project perpendicularly upwards from the bottom of the casting mold into the casting
space of the casting mold. Alternatively or additionally, the detachable attachable
lid member 11 can be configured to cooperate with the headed lifting stud 2 so that
the detachable attachable lid member 11 can be detachable attached to the headed lifting
stud 2. An advantage of this is that in such case, the detachable attachable lid member
11 can in such case protect the recess in the outer surface 7 of the concrete product
3 and/or the headed lifting stud 2 also in a situation where the cup member 4 and
the detachable attachable support member 8 is removed from the concrete product 7
for example after that the concrete of the concrete product 3 has hardened.
[0018] The cup member 4 is preferably, but not necessarily, made of plastic or polymer such
as of thermoplastic. An advantage of this is that the original shape of the cup member
4 remains also during vibrating of the concrete: result is a correct shape of the
open top space 6 of the cup, which promotes correct positioning of the headed lifting
stud 2 with respect to the open top space 6 of the cup. Thermoplastic is also durable,
which enables to re-use the cup member 4 in case the cup member 4 is removed from
the concrete product 3 for example once the concrete product 3 has been lifted by
using the headed lifting studs 2 to its final mounting place in a building construction.
[0019] The detachable attachable support member 8 is preferably, but not necessarily, made
of plastic or polymer such as thermoplastic. An advantage of this is that the original
shape of the detachable attachable support member 8 remains also during vibrating
of the concrete and the result is a correct shape of the open top space 6 of the cup,
which promotes correct positioning of the headed lifting stud 2 with respect to the
open top space 6 of the cup. Thermoplastic is also durable, which enables to re-use
the detachable attachable support member 8 for example once the concrete of concrete
product 3 into which the headed lifting studs 2 has been casted by using the cup device
1 has been cured.
[0020] The first connection means 12 by means of which the detachable attachable support
member 8 is attached to the cup member 4 comprises preferably, but not necessarily,

stud 2 while the head of a headed lifting stud 2 is pressed between the first abutment
surface 18 and the first projections 17 projecting from the first deflectable leg
means 15. An advantage of this is that the headed lifting stud 2 will be both axially
and radially releasable locked into position with respect to the detachable attachable
support member 8. Because the headed lifting stud 2 will be both axially and radially
releasable locked into position with respect to the detachable attachable support
member 8, it is possible to use the detachable attachable support member 8 as a handle
for the headed lifting stud 2 when placing and detachable attaching the headed lifting
stud 2 into position with respect to the inner surface 5 of the cup member 4.
[0022] Said plurality of first deflectable leg means 15 of the second connection means 13
extend from a central portion 19, which can be in the form of a central circular portion,
of the detachable attachable support member 8, and two fastening portions 20 extend
diametrically from the central portion 19, so that each fastening portion 20 is provided
with a snap retainer 14 of the first connection means 12 for detachable attaching
the detachable attachable support member 8 to a circumferential edge 23 of the cup
member 4. In the embodiment illustrated in the figures the central circular portion
19 has partly the shape of a truncated cone 25 so that a bottom of the central circular
portion 19 forms the first abutment surface 18. In the embodiment illustrated in the
figures, the cup member 4 comprises a circular edge ring 24 and the circumferential
edge 23 of the cup member 4 is provided at the circular edge ring 24.
[0023] The opening 9 of the cup member 4 of the cup device 1 is preferably, but not necessarily,
a central opening provided with a slit configuration 21 extending from the opening
9 and disposed around the opening 9. Such slit configuration 21 extending from the
opening 9 and disposed around the opening 9 allows to push a head of the heads lifting
stud 2 through the opening 9 even if the cross-section of the opening 9 is smaller
than the cross-section of a head of the headed lifting stud 2.
[0024] The cup member 4 of the cup decide 1 can for example have an opening 9 in the form
of a central opening and have a slit configuration 21 consisting of a plurality of
slits 22 each extending from the central opening to form a symmetrical slit configuration
21 around the opening 9 having independently movable flexible flaps 34 between adjacent
slits 22. Such slit configuration 21 extending from the opening 9 and disposed around
the opening 9 allows to push a head of the heads lifting stud 2 through the opening
9 even if the cross-section of the opening 9 is smaller than the cross-section of
a head of the headed lifting stud 2.
[0025] Alternatively the cup member 4, can as illustrated in figures 10 to 12, be in a two-part
form so that the cup member 4 comprising a top cup part 28 and a bottom cup part 29.
In this alternative embodiment of the cup member 4, the top cup part 28 is detachable
