Abstract
The invention elates to a hoop lock comprising a lock body and a hoop. The hoop can be coupled a its hoop ends to the lock body and latched thereto in the coupled state wherein two force cells spatially separated from one another are arranged in the lock body for the reception of the hoop ends. Each force cell is associated with a latching arrangement for a hoop end which is adjustable between a latched state and a released state and which can be actuated via a locking unit. At least one latching arrangement has a bolt element whose side remote from the inserted hoop end is supported at the force cell in the latched state.
Description
FIELD OF THE INVENTION
The invention relates to a hoop lock comprising a lock body and a hoop which can be coupled to the lock body at its hoop ends and which can be latched thereto in the coupled state.
BACKGROUND OF THE INVENTION
There is a problem with such locks in that the locking mechanism can be deformed or displaced by blows onto the lock body in the latched state such that the hoop can also be pulled out of the lock body in the latched state. While actions to strengthen the lock body could result in an improved protection of the locking mechanism, these would, however, disadvantageously increase the weight of the lock.
SUMMARY OF THE INVENTION
It is the object of the invention to provide a hoop lock of the kind initially mentioned which is secure against being broken open while having the lowest possible weight.
This object is satisfied in accordance with the invention in that two force cells, which are spatially separated from one another, are arranged for the reception of the hoop ends and in that each force cell is associated with a latching arrangement for a hoop end which can be adjusted between a latched state and a released state and which can be actuated via a locking unit, with at least one latching arrangement comprising a bolt element whose side remote from the inserted hoop end is supported at the force cell in the latched state.
The support in accordance with the invention of the bolt element at the force cell prevents the bolt element from being moved out of engagement with the hoop end in the latched state. The support of the bolt element at the force cell can take place either directly or indirectly via an additional, separate component. Deformations of the bolt actuations due to blows onto the lock body do not impair the latched state since such deformations have no effect on the support of the bolt element at the force cell. Break-open forces applied from the outside which attempt to move the bolt element out of its latched position in the latched state are absorbed by the force cell in accordance with the invention and rendered ineffective in this way.
It is particularly preferred if, in at least one force cell, both the side of the inserted hoop end remote from the bolt element and the bolt element are supported at the same component of the force cell. A particularly stable force cell is provided in this way.
At least one force cell can have walls formed in particular as drill protection and/or blow protection, which at least partly bound a protected space for at least the hoop end and the bolt element, with the force cell serving not only the absorption of forces acting on the hoop end and the bolt element, but also additionally increasing the resistance to other external influences such as attempts to cancel the latching engagement between hoop end and bolt element by drilling it open.
In a particularly preferred practical embodiment of the invention, at least one force cell has a U section whose open side faces the other force cell. The U section can be arranged such that the hoop end is inserted at the side between the limbs of the U and consequently extends perpendicular to the limbs of the U in the inserted state. It is preferred if a side of the hoop end remote from the bolt element is supported at the U base connecting the U limbs and the bolt element is supported at at least one U limb. The hoop end and the bolt element are in this way surrounded on three sides by section walls and protected against external influences. This embodiment in particular provides an advantageous protection of the hoop end at the end face of the lock body by the U base of the U section.
The latching arrangement can be made in multiple parts and have, in addition to the bolt element, a positioning element which can be actuated via the locking unit and via which the bolt element is indirectly supported at the force cell. It is also alternatively possible to provide a one-part latching arrangement in the form of a bolt element supported directly at the force cell which both cooperates with the hoop end to be inserted and can be actuated via the locking unit.
In a preferred embodiment of a multiple part latching arrangement, the positioning element is formed as a pivoted lever comprising an actuating arm and a support arm. The pivoted lever can be pivoted via the actuating arm by means of the locking unit between a latched position in which the bolt element is supported at the force cell via the support arm, and is thus secured in a latched position by the support arm, and a released position in which it is possible to move the latching element out of its latched position.
A pivotal support of the pivoted lever at the force cell can take place, for example, by the pivoted lever extending between opposite walls of the force cell and being supported at apertures in the walls forming support regions.
It is particularly preferred if the latching arrangement is made self-locking. This can be done, for example, by dead travel and/or play of the positioning element. It can be achieved with the self-locking that the securing effect of the positioning element is not weakened or cancelled in typical break-open attempts such as blows onto the lock body, but is rather strengthened.
A preferred possibility for implementation of such a self-locking of the latching arrangement consists of supporting the positioning element such that it can be moved beyond a maximum latched position which can be set by the locking unit, with the bolt element being supported and/or secured at the force cell in every additional position via the positioning element. In this way, the inertia of the positioning element can be utilized which, in the event of blows onto the lock body, results in a relative movement between the force cell which moves along with it and the positioning element.
It is preferred if the positioning element can be brought into engagement with the bolt element by such a relative movement and can, in particular, be clamped or wedged between the bolt element and the force cell.
Due to the self-locking effect in accordance with the invention, exactly the opposite effect of that intended in such break-open attempts is consequently achieved by blows onto the lock body.
In a further preferred embodiment of the invention, the bolt element can be moved out of a latched position in the released state by pulling the hoop end out of the force cell. It is preferred if the bolt element is pre-stressed into the latched position by a spring member arranged in or projecting into the force cell. The restoring force of the spring member is preferably set such that the inserted hoop is held at the lock body secure against falling out.
Further preferred embodiments of the invention are also given in the dependent claims, the description and the drawing.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
FIG. 1
shows the hoop lock in accordance with the invention, which comprises a lock body
10
and a hoop
12
, in a latched state in which the hoop ends
14
of the hoop
12
are inserted into force cells
16
of the lock body
10
which are described in more detail in the following and which are each arranged in the region of a tube end spatially separated from one another in a tubular housing
28
.
A latching arrangement, which is arranged in the force cell
16
and which comprises a bolt element
18
in the shape of a roller and a positioning element in the form of a pivoted lever
20
, is provided for the latching of each hoop end
14
. In the latched state, the bolt
18
is located in a latched position in which it engages in a bolt receiver
15
of the hoop end
14
matched to its shape and is supported at the force cell
16
by a support arm
34
of the pivoted lever
20
. The bolt element
18
is secured in the latched position in this way. An actuating arm
33
of the pivoted lever
20
, which forms an angle of more than 90° with the support arm
34
and which projects out of the force cell
16
, is coupled to the one end region of a linkage
26
which is connected to an actuating member
50
at its opposite end region. The linkage and the actuating member
50
form an actuating assembly via which the two pivoted levers
20
can be pivoted between the latched position shown and a released position by means of a lock cylinder
23
of a locking unit
22
indicated only schematically.
The actuating member
50
is rotationally fixedly connected to the lock cylinder
23
so that the linkage
26
can be adjusted along its longitudinal axis via actuating pins
52
of the actuating member
50
by turning the lock cylinder
23
by means of an inserted key (not shown).
The constructionally identical force cells
16
each comprise a U-shaped section
17
made of hardened metal with section walls
36
which form the limbs of the U and extend parallel to one another. The open sides of the U sections
17
face one another and are arranged so that the hoop ends
14
of the hoop
12
can be inserted between the section walls
36
.
The U sections
17
are each positioned in the lock body
10
relative to the insertion openings for the hoop
12
formed in the lock body
10
such that the side of the hoop end
14
remote from the latching arrangement
18
,
20
is supported at the section wall forming the U base
35
.
Apertures
37
are formed in the section walls
36
at whose bounding edges the bolt element
18
and the positioning element
20
, which extend between the section walls
36
, are supported.
The apertures
37
comprise for this purpose one reception region
37
a
each for the roller
18
which allows a movement perpendicular to the inserted hoop end
14
and thus in the longitudinal direction of the section walls
36
. The pivoted lever
20
is pivoted at support regions
37
b
of the apertures
37
and simultaneously supported such that a translatory movement of the pivoted lever
20
perpendicular to the inserted hoop end
14
is not possible.
The pivot region for the pivoted lever
20
is bounded by the shape of the apertures
37
such that the bounding edges of the apertures
37
form abutment surfaces
37
c
for the support arm
34
of the pivoted lever
20
.
The section walls
36
are provided in the region of their free ends with recesses
36
a
into which there engage protrusions
25
of a reception housing
24
for the locking unit
22
shown only schematically. The U sections
17
are in this way fastened secure against removal at the reception housing
24
and coupled to one another via the reception housing
24
. The U sections
17
can be latched to the reception housing
24
by being pushed onto the projections
25
.
FIG. 2
shows additional components not shown in
FIG. 1
which are arranged in the region of the force cells
16
. The components in question are, on the one hand, a spring arrangement of plastic which comprises a plate-like carrier
32
which extends perpendicular to the section walls
36
, which is arranged outside the U section
17
and which adjoins the side edges of the U section
17
. The carrier
32
is connected in one piece to perpendicularly protruding spring tongues
30
,
31
which project into the force cell
16
between the section walls
36
.
A spring tongue
30
whose free end regionally engages around the roller
18
serves to hold the roller
18
in its latched position even when the pivoted lever
20
is pivoted into the released position in which the roller
18
is not secured by the support arm
34
and thus is not supported at the U section
17
via the pivoted lever
20
.
The bolt element
18
can be moved out of its latched position in this released state by pulling the hoop end
14
out of the force cell
16
against the resetting force of the spring tongue
30
perpendicular to the inserted hoop end
14
. The spring tongue
30
is matched to the hoop
12
such that its resetting force is sufficiently great in order to prevent the hoop
12
from falling out due to its own weight alone; the inserted hoop
12
is therefore held secure against falling out at the lock body
10
in the released state by the bolt elements
18
pre-stressed into their latched position.
The other spring tongue
31
attached to the carrier
32
serves as a holding member for the pivoted lever
20
. The holding member holds the pivoted lever
20
in the support regions
37
b
of the section walls
36
. As a result, only pivotal movements of the positioning element
20
are possible, while translatory movements are prevented by the holding member
31
.
FIG. 2
further shows a cushion, buffer or damper member
54
made of plastic which is arranged on the inner side I of the lock body
10
facing the hoop
12
between the housing
28
of the lock body
10
and the U section
17
.
A lug
55
of th damper member
54
projects into the force cell
16
up to the bolt element
18
. The damper elements
54
arranged at both force cells
16
form an additional protection against breaking open which cushions blows onto the housing
28
of the lock body
10
. This damping is the subject of a German patent application of the applicant having Serial No.: DE 100 26 701.7 submitted on May 30, 2000 and whose disclosed content is herewith included in the present application by reference.
The carrier
32
arranged at the outside of the lock body
10
between its housing
28
and the U section
17
likewise provides such blow protection.
On the one hand, great external forces can be absorbed in a closed system by the force cells
16
in accordance with the invention. On the other hand, the force cells
16
allow a geometrical arrangement of the latching arrangements or the bolt elements such that external forces are distributed more uniformly and force or strain peaks are avoided. Distribution of external force takes place in a manner of speaking both spatially, namely by an enlarging of the expansion region, and temporally, namely by a reduction in mass accelerations. The above-mentioned cushions, buffers or dampers
54
also work in this sense.
It can in particular be seen from
FIG. 3
that the support arm
34
of the positioning element
20
is formed in a fork shape so that the spring member
30
and the holding member
31
can project through the fork arms of the support arm
34
.
Moreover, recesses
27
are shown in
FIG. 3
in the end regions of the linkages
26
into which the respective free end of the actuating arm
33
of the pivoted lever
20
engages. The actuating arms
33
are arranged in the recesses
27
with play. This play in each case allows a self-locking function of the latching arrangement
18
,
20
which is explained in more detail in the following in connection with FIG.
8
.
Guide openings
53
are formed in regions of the linkages on top of one another which cooperate with the actuating pins
52
of the actuating member
50
which can be rotated via the lock cylinder
23
of the locking unit
22
. One of the two arms of each guide opening
53
serves for the reception of the actuating pin
52
displacing the relevant linkage
26
, while the other arm allows an unimpeded movement of the actuating pin
52
serving the displacement of the other linkage
26
. In the embodiment shown, the right hand actuating pin
52
in
FIG. 3
serves the movement of the lower linkage
26
, while the upper linkage
26
is moved via the left hand actuating pin
52
.
It can be seen in particular from
FIG. 4
that there is no, or at most only little, play present at each of the two force cells
16
between the U base
35
of the U section and the hoop end
14
, between the hoop end
14
and the roller
18
, between the roller
18
and the fork-like support arm
34
of the pivoted lever
20
and between the pivoted lever
20
and the section walls
36
.
In the latched state shown, the hoop end
14
is thus supported directly, and the bolt element
18
indirectly via the positioning element
20
, at opposing sides of the same component of the force cell
16
, namely the U section
17
. Movements of the bolt element
18
are not possible in this latched position supported and secured by the positioning element
20
. This latched state cannot be effected by attempts to break open, such as blows onto the lock body
10
, either since deformations of the linkages
26
possibly caused thereby do not alter the immobility of the bolt elements
18
.
FIG. 5
shows in particular the actuating arm
33
of the pivoted lever
20
projecting through the recess
27
of the linkage
26
.
In particular the support of the pivoted lever
20
in the support regions
37
b
of the apertures
37
formed in the section walls
36
can be seen from the perspective view of FIG.
6
. For this purpose, the fork arms of the fork-like support arm
34
are rounded at their end remote from the bolt element
18
so that they form support surfaces
34
b
with which the pivoted lever sits in the correspondingly shaped support regions
37
b
of the sections walls
36
or the apertures
37
.
In particular the bolt reception
15
of the hoop end
14
shaped in accordance with the outer contour of the roller-shaped bolt element
18
can be seen in FIG.
7
.
The side view of
FIG. 8
shows a latched state in which the pivoted lever is located in a latched position which can be set to a maximum via the locking unit
22
, i.e. the pivoted lever
20
can not be turned further in an anti-clockwise direction (with respect to
FIG. 8
) by means of a key inserted into the lock cylinder
23
, even though a small intermediate space is present between the support arm
34
and the corresponding abutment surface
37
c
of the apertures
37
which would permit a further pivotal movement of the pivoted lever
20
in an anti-clockwise direction.
However, the actuating arrangement comprising the linkage
26
does not hinder the pivoted lever
20
from such a further movement beyond the maximum latched position which can be set, since the actuating arm
33
of the pivoted lever
20
is arranged in the recess
27
of the linkage
26
with play (cf. in particular FIG.
3
). There is thus a dead travel or play of the pivoted lever
20
located in the maximum latched position which can be set, whereby a self-locking function of the latching arrangement
18
,
20
is realized.
The inertia of the pivoted lever
20
results in the pivoted lever
20
being further pivoted in a counter-clockwise direction relative to the U section
17
until it adjoins the abutment surface
37
c
in the event of blows onto the inside I of the lock body
10
.
This further pivotal movement of the pivoted lever
20
is associated with a stroke of a part of the support surface
34
a
of the pivoted lever
20
facing the bolt element
18
in the direction of the hoop end
14
, whereby the bolt element
18
is pressed against the hoop end
14
. This stroke can be absorbed by a small amount of play, for example between the U base
35
of the U section
17
and the hoop end
14
.
The size of the stroke depends in particular on the relative arrangement between the bolt element
18
and the pivoted lever
20
and on the course of the support surface
34
a.
In the embodiment shown, the support surface
34
a
extending perpendicular to the sides of the support arm
34
in the maximum latched position which can be set in accordance with
FIG. 8
forms an angle other than 90° with a line connecting the pivot axis S of the pivoted lever
20
and the center axis R of the bolt element
18
.
Blows onto the inner side I of the lock body
10
thus result in a self-locking of the latching arrangement
18
,
20
which results in a wedging of the support arm
34
of the pivoted lever
20
between the bolt element
18
and the U section
17
.
The support arm
34
of the pivoted lever
20
can also be further removed from the abutment surface
37
c
than shown in
FIG. 8
in the maximum latched position which can be set. Furthermore, the support surface
34
a
does not need to contact the bolt element
18
in the maximum latched position which can be set. The relative arrangement between the bolt element
18
and the pivoted lever
20
takes place in any case such that the bolt element
18
is secured in its latched position by the support arm
34
of the pivoted lever
20
not only in the maximum latched position which can be set, but also in any position of the pivoted lever
20
beyond this.
FIGS. 9 and 10
show a further embodiment of the invention in which the bolt element
118
is bent in a U-shaped manner and extends between the section walls
36
of the U section
17
. The bolt element
118
is pre-stressed in its shown latched position by a spring member
130
only indicated in
FIG. 9
which is arranged between the U limbs
118
a
of the bolt element
118
.
A positioning element
120
can be displaced perpendicular to the U limbs
118
a
of the bolt element
118
via the locking unit of the lock, whereby it is guided in the apertures
37
of the section walls
36
of the U section
17
.
The U limbs
118
a
of the bolt element
18
are each provided at their free ends with extensions arranged at the side which form engaging sections
119
a.
A released state of the latching arrangement
118
,
120
is shown in
FIGS. 9 and 10
in which the extensions
119
a
of the bolt element
118
can be moved past the positioning element
120
or through recesses
120
a
of the positioning element
120
.
The bolt element
118
can thus be moved out of its latched position in the released state by pulling the hoop end
14
out of the force cell
16
against the resetting force of the spring member
130
.
The bolt element
118
is supported at the U section
17
in its latched position and thus secured in its latched position via the positioning element
120
by a displacement of the positioning element
120
via the locking unit and by a suitable actuating arrangement interposed between the locking unit and the positioning element
120
.
FIGS. 11 and 12
show a further embodiment of the invention in which the latching arrangement is made in one part and comprises a bolt element
218
which cooperates with the hoop end
14
at a side bent in accordance with the bolt reception of the hoop end
14
and which has an actuating arm
233
and a fork-like support arm
234
at its sides remote from the inserted hoop end
14
. The actuating arm
233
disposed between the fork arms of the support arms
234
is bent with respect to the support arm
234
such that a hook-like actuating section
226
a
of an actuating member
226
, which is perpendicularly adjustable relative to the inserted hoop end
14
via the locking unit of the lock, can pivot the bolt element
218
in a clockwise direction (with respect to
FIG. 11
) from its shown latched position into a released position via the actuating arm
233
.
Whereas the bolt element
218
is supported in the latched position via its support arm
234
at support sections
217
a
which bound apertures
37
in the section walls
36
of the U section
17
, the bolt element
218
can, in the released state which can be set by pivoting, be moved out of its latched position, past the support sections
217
a
and, with its support arm
234
, into a region of the apertures
37
adjacent to the support section
217
a.
The bolt element
218
is secured in the latched position via its support arm
234
in the latched state by a securing section
226
b
of the actuating member
226
.
The pivot movement of the bolt element
218
from the latched position into the released position can take place against the resetting force of a spring member. Furthermore, a spring member can be provided which pretensions the bolt element
218
into engagement with the hoop end
14
and against whose resetting force the bolt element
218
can be moved out of the latched position into the unlatched position by pulling the hoop end
14
out of the force cell
16
.
A slope
226
c
of the actuating member
226
bounding the securing section
226
b
ensures that the bolt element
218
is reliably moved out of the unlatched position back into the latched position via its support arm
234
when the actuating member
226
is adjusted in the direction of the hoop end
14
via the locking unit.
