The invention relates to a device for connecting and disconnecting with and
from a holder respectively by means of a lock a body to be retained, for
example, a bicycle, a barrier, a swing gate or a different body.
Such a device is known. For retaining a bicycle this known device comprises
a pole anchored in the ground and provided with a bracket for holding a
bicycle frame in the upright position and with a retaining chain connected
with the pole and adapted to be locked with a key. Fastening a bicycle to
such a device requires more manipulations than putting a bicycle up in a
stand. For passing around the chain and fastening the lock the user needs
at any rate both hands. When the bicycle is loaded with purchases, this
may be an inconvenience which hinders practical use.
The invention has for its object to construct a device of the kind set
forth in a manner such that no additional manipulations are required for
connecting the body to be retained with the holder.
This is achieved by a device of the kind described characterized by a
holder having an entrance opening for the body, by at least one member
arranged on the holder for retaining in the holder the body put into it,
said retaining member being urged by the body against spring force out of
an inoperative position into the retaining position, by a mechanism
co-operating with the retaining member for locking this retaining member
in its retaining position, by an externally, for example, manually
operable member for unlocking the locking mechanism and by means operable
by the lock for guarding and releasing the unlocking member in a manner
such that in the inoperative state of the device the unlocking member
guards the lock in its open position and in the retaining position of the
device the lock can be operated and guard the unlocking member in its
closed position.
A preferred embodiment is characterized in that the lock is constructed so
that only in the closed position of the lock a key can be removed
therefrom and be inserted therein.
It is possible to use a coin mechanism guarding the lock in its position
and releasing the key for operation not until a coin is thrown in and the
retaining member is moved into its retaining position.
The device embodying the invention preferably has the feature that the
holder comprises a stop which is movable by the body against spring force
and which is coupled by a spring or a catching pawl with the retaining
member and the locking mechanism.
In this case the retaining member may be coupled with the stop by a spring
and be formed by an arm pivotable about an axis, whilst the locking
mechanism may be provided with a cam disc secured on the shaft and a
springloaded pawl co-operating herewith, wherein the unlocking member may
be positively coupled with said pawl.
In a further embodiment the retaining member is formed by a ring portion
adapted to turn about its axis, one end of which co-operates with a
catching pawl movable by the stop in the path of the ring, whilst the
locking mechanism is provided with a lug arranged on said ring portion and
a spring-loaded pawl co-operating therewith and the unlocking member is
positively coupled with the last-mentioned pawl.
There may be used a construction in which the unlocking member is formed by
a first bar adapted to turn about its axis and having a transverse arm for
actuating unlocking member from the outside, by a control-member acting on
said transverse arm, for example, a push-button and in which the lock
actuates a second bar being parallel to said rotatable bar and being
axially displaceable in a manner such that in the inoperative state of the
device the transverse arm of the first bar guards the second bar against
axial displacement by the lock and in the operative state of the device
and in the closed state of the lock the second bar guards the first bar
through its transverse arm against a turn.
The invention furthermore relates to a bicycle stand provided with a
retaining device with a lock, a holder having at least one retaining
member, a locking mechanism, an unlocking member and a lock, said holder
being capable of receiving a part, for example, a wheel of the bicycle to
be stored and retained.
Advantageously said bicycle stand can be provided with a retaining device
of the type mentioned above, the movable stop of which carries a roller
connected through a coupling member with the retaining member and the
locking mechanism in such a way that these parts can only be operated
after a given minimum rotation of said roller in the direction of rotation
corresponding with the driving into the stand of a wheel of a bicycle.
Such a bicycle stand has the advantage that it cannot be operated by e.g.
the introduction of a piece of wood or the like so that it can be
prevented that by misbehaviour a stand is made unusable by the fact that
after the introduction of a piece of wood and the introduction of a coin
the key can be removed from a bicycle stand, causing said stand to be
unusable during a certain time, while further even the lock has to be
replaced by another lock namely a specimen on which the stolen key does
not fit.
Advantageously the coupling member comprises a friction-coupling member.
In order to ensure that by driving a bicycle wheel into the retaining
device this wheel can make the stand to operate preferably the embodiment
is used, the roller of which has a surface stimulating the frictional
contact with the tire of the wheel of a bicycle to be retained. The roller
may have generally the shape of a diabolo. Also the surface of the roller
can be provided with ribs.
The invention will now be described with reference to a drawing of a number
of arbitrarily chosen embodiments, to which the invention is, however, not
limited.

device to operate.
FIG. 1 illustrates a row of devices embodying the invention intended for
retaining the front wheel of a bicycle 2. The devices 1 comprise a pole 4
anchored in the ground by a block 3 and having a coin lock 5 fastened to
it. The poles 4 are laterally coupled with one another by a transverse
beam 6, which enhances the rigidity of the row of devices 1.
Each pole 4 is furthermore provided with a holder 7 having an entrance
opening 8 for the front wheel 9 of a bicycle 2, said holder being provided
with means to be decribed hereinafter for retaining the front wheel of a
bicycle.
The holder 7 comprises two plates 10, 11, which are coupled through
prismatic supports 12 with the transverse beam 6 so that the plates 10, 11
can practically not be laterally deformed. At the top the plates 10, 11
are furthermore coupled with one another by a metal bridge part 13.
The coin lock 5 has a coin slot 14, a keyhole 15, a coin window 38 and a
push-button 16. A trap 17 to be opened by the owner by means of a private
key serves to empty the till from time to time.
FIG. 2 shows further details.
The elevational view of FIG. 3 shows two pairs of rocking arms 20, 21 and
22, 23 arranged between the plates 10, 11 and adapted to pivot about
shafts 18, 19. At their ends directed to the entrance opening 8 the arms
20, 21 have a diabolo-shaped roller 24 of synthetic resin and the arms 22,
23 have a roller 25. At their other ends the arms 20, 21, 22, 23 are
loaded by tensile springs 26, 27, 28, 29, which urge the rollers 24, 25
towards one another. This configuration ensures that a wheel in the
entrance opening is engaged at several position of the circumference inter
alia by the rollers 24, 25 so that without touching the plates 10, 11 a
wheel assumes a stable position between the rollers 24 and 25 and a roller
40 to be described hereinbelow.
On the rear side the pole 4 is provided with a bracket 30 for coupling with
the transverse beam 6.
FIG. 4 schematically shows the position of the rocking arms 20, 22 in the
rest position in which they are bearing on stops 31, 32.
FIG. 5 shows the position in a situation in which the front wheel 33 of a
bicycle 34 has passed through the entrance opening 8 and has urged the
rollers 24 and 25 downwards and upwards respectively.
FIG. 6 shows the position after the insertion of the front wheel 35 of a
bicycle 36. The front wheel 35 is materially smaller than the front wheel
33 of FIG. 5. Nevertheless the present construction can provide an
excellent stability also for this much smaller wheel.
FIG. 7 is an elevational view from which it will be apparent how the wheel
35 can be held in its stable position by the rollers 24, 25 and 40.
FIG. 8 shows in an elevational view corresponding to FIG. 7 a front wheel
37 having a considerably larger width than the front wheel 35 of FIG. 7,
though it has the same diameter as the front wheel 35. Even for this broad
front wheel 37 the device ensures full stability of the position of the
wheel without the need for frictional contact with the plates 10, 11.
FIG. 9 shows a device embodying the invention in the free state, that is to
say, in the state in which no front wheel of a bicycle is yet blocked.
When introduced into the entrance opening 8 the front wheel 39 comes into
contact with a roller 40, which serves for inwardly moving a retaining
member formed by two pivotable arms 41, 42 to retain the front wheel 39 in
a manner to be described further with reference to FIGS. 10, 11, 12, 13
and 14.
These pivotable arms are coupled with associated cam discs 43, 44, which
can be rotated by a tractive force exerted on two springs 45, 46. The
springs 45, 46 are coupled with the free ends of pivotable arms 47, 48,
which can be displaced to the rear, i.e. to the left viewed in the
drawing, under the influence of the displacement of the roller 40 when a
front wheel 39 is inserted. The roller 40 is carried by a pivotable frame
49 and is urged into its rest position shown in FIG. 9 by a tensile spring
50.
The cam discs 43, 44, as shown in FIG. 11, can be blocked for resetting the
pivotable arms 41 and 42 by lever arms 51, 52, which are coupled through
coupling arms 53, 54 with a further cam disc 55. The coupling arm 53 is
engaged by a tensile spring 56, which urges the lower end of the coupling
arm 53 and hence the part of the cam disc 55 coupled herewith to the left
as viewed in the drawing. Therefore, as soon as the cam discs 43 and 44
have attained the position shown in FIG. 11, the corresponding ends of the
lever arms 51, 52 will move in the direction of the rotary shafts of these
cam discs 43, 44, so that the assembly is locked in the manner shown. Stop
members 57, 58 serve to limit the stroke of the cam discs 43, 44. From
FIG. 11 it will furthermore be apparent that in the locked state a
displacement of the cam discs 43, 44 in both directions is blocked, that
is to say, on the one hand by the lever arms 51, 52 and on the other hand
by the stop members 57, 58.
A stop member 59 co-operates with the cam disc 55 for limiting the angular
displacement thereof.
It will be obvious that blocking of the front wheel 39 by the arms 41, 42
can only be obviated by a displacement of the lever arms 51, 52 such that
the cam discs 43, 44 are released for rotation. This can only be achieved
by a corresponding rotation of the cam disc 55. Such a rotation can take
place by rotating a shaft 60 coupled with the cam disc 55 in a manner to
be described hereinbelow.
FIG. 15 illustrates how via the shaft 60 a rotary movement can be produced
for turning, as stated above, the cam disc 55 and hence for releasing the
wheel 39 by displacing the pivotable arms 41, 42 into the position shown
in FIGS. 9 and 10. The shaft 60 extends through the hollow pole 4. The
lower end 61 has a tapering shape so that the shaft 60 can readily find
the central aperture 62 of a cam disc 55. This central aperture 62 is
surrounded by a sleeve 65 having two opposite slots 63, 64, into which
fits the shaft 60. Extensions 66, 67 provided on the shaft 60 co-operate
with the slots 63, 64. In this construction after assembling the rotation
of the shaft 60 causes the cam disc 55 to rotate.
The shaft 60 is coupled with a tag 68, which in the position shown in FIGS.
15 and 17 blocks a downward movement of a shaft 69. The tag can be moved
into the position shown in FIGS. 15 and 17 by external, manual depression
of a push-button 70, which engages the tag 68 through a pin 71.
The position shown in FIGS. 15, 16, 17 is the inoperative position of the
device. In this position the key cannot be operated, even not after a coin
has been thrown in.
The push-button 70 is urged outwards by the tension of a spring 72.
The vertical displacement of the shaft 69 can take place in the manner
illustrated in FIGS. 16 and 19 by inserting a key (not shown) into the
keyhole 15 and by turning the key so that a tag 72 is turned to exert a
force via a slot 73 on a pin 74 coupled with the shaft 69 so that the
shaft 69, which can only be displaced upwards and downwards, is shifted
upwards or downwards respectively.
The broken lines schematically indicate an automatic coin machine 75, which
co-operates with the device shown in a manner such that solely after the
reception of the correct coin the key can be turned for locking the device
and subsequently withdrawing the key.
It should be noted that after the device embodying the invention is brought
into the position shown in FIG. 12 and before the coin is inserted and the
key is turned, blocking can be obviated by depressing the pushbutton 70.
From the foregoing it will be obvious that this is still possible, since
the displacement of the tag 68 is not yet blocked by the shaft 69. Locking
can only become permanent by turning the key as shown in the position
indicated in FIGS. 18, 19 and 20. This turn in itself can only take place
after the correct coin is thrown in and after the front wheel is blocked
as illustrated in FIG. 12.
FIGS. 21 to 25 show a further embodiment of the device in accordance with
the invention. In this variant the retaining member is formed by a ring
portion 76 adapted to turn about its axis, one end of which co-operates
with a catching pawl, whereas the other end 79 can block, upon rotation,
the entrance opening 8 of the device in the manner shown in FIG. 23. The
ring portion 76 has a cam surface 80 and a pawl 82 co-operating herewith
and loaded by a spring 81.
In FIGS. 21 to 25 the elements corresponding with those of the embodiment
shown in FIGS. 9 to 14 are designated by the same reference numerals.
Their description may be dispensed with.
By displacing the roller 40 from the position shown in FIGS. 21 and 22 into
the position shown in FIGS. 23 and 24 a tensile spring 83 exerts a
tractive force on a catch 84, which can pivot through a slot 85 about a
pin 86. To the top end of the catch 84 is pivoted a carriage 88 adapted to
move horizontally in a slot 87 and having the aforesaid catching pawl 78
pivoted to it. The catching pawl 78 is urged by a tensile spring 89 in the
axial direction of the carriage 88.
During the inward displacement of the roller 40 the carriage 88 is
displaced to the rear, i.e. to the left as viewed in the drawing so that
the catching pawl 78 exerts such a force on said end of the ring portion
76 that the latter is rotated into the position shown in FIG. 23. This
rotation is performed against the tractive force of a spring 90. The
situation illustrated in FIG. 23 is a rest position, since herein the cam
surface 80 co-operates with the pawl 82. In analogy with the statements
made with reference to FIGS. 9 to 20 it will be obvious that the
co-operation between the cam surface 80 and the pawl 82 can solely be
obviated by turning the shaft 60. In this respect reference is
particularly made to FIGS. 15 and 20 and to the associated description.
FIG. 26 shows a device 90 comprising a barrier 92 supported by a frame 91,
said barrier bearing in the horizontal position on a support 93, which has
an entrance opening 94 for the free end 95 of the barrier, which opening
can be closed by a retaining member 96 in the closed position of the
barrier 92 shown in FIG. 26. The retaining member 96 corresponds to the
ring portion 76 of the preceding embodiment. FIG. 26 does not show further
details of the operation of the device 90 and of the locking mechanism 97.
It will be sufficient to state that the locking mechanism 97 corresponds
to the embodiment shown in FIGS. 21-25.
FIG. 27 shows a horizontally mobile gate 98, which can be locked in a
closed position by means of an ear 99 and a locking mechanism 100, which
corresponds with that of FIGS. 21-25.
With reference to FIGS. 28 through 35 a description will now be given of a
variant, in which the rotation of the roller 40 with the driving of a
front wheel 39 of a bicycle into the retaining device is used for the
operation of the retaining member and the locking mechanism, in such a way
that only by driving into the stand a wheel of a bicycle the stand can be
used and the key can be removed after introducing a coin.
Different from the embodiments described hereinbefore the roller 40 is not
fully idle but is through a friction coupling member 101 drawn in FIG. 34
coupled with a hook member 102. The friction coupling member 101 comprises
a pressure spring 10, that cooperates with the hook member 102 at the one
side and at the other side with a nut 105 provided on the shaft 104 of the
roller 40, in such a way that by a rotation of the wheel 40 the hook
member 102 can also be subjected to rotation.
In FIGS. 28 through 35 elements drawn and discussed before have been
indicated by the same numerals as above. As far as not necessary their
description will be omitted.
FIG. 28 shows the moment of unlocking of the retaining device and the
making free of the wheel 39.
A slide 106 can be shifted in horizontal direction and is urged by a
pulling spring 107 into the right hand direction in the drawing, to a rest
position. The slide 106 carries at its left hand end a pin 108 cooperating
with a recess 110 present in a cam disc 199. Under the influence of the
displacement of the slide 106 this cam disc 109 can rotate. During the
displacement according to FIG. 28, indicated with an arrow 111 a
corresponding rotation 112 of the cam disc 109 takes place.
FIG. 30 shows, how the hook member 105 at the shifting as a result of the
presence of a protrusion 113 cooperating with a pin 114 present on the
slide 106, is in first instance moved above in the direction of an arrow
115, and afterwards only by the subjection to a downward rotation of the
hook member 102 as a result of the introduction of a wheel 39 is moved
downwardly, in such a way that, as indicated in FIG. 31, it can be brought
into a hooking cooperation with the pin 144 with a recess 116, so that
with a displacement in the left hand direction of the hook member 102 the
slide 106 is displaced as a result of the introduction over a further
distance of the wheel 39.
FIG. 32 shows the activation caused hereby of the locking by the introduced
front wheel 39 in the situation, in which the hook member 102 has
displaced the slide 106 into the left hand direction against the pulling
spring 107. The cam disc 109 has been rotated by said displacement of the
slide in such a position, that a flat face present on the disk 109 is in
abutting relationship with the coupling arm 54, causing the cam disc 55 to
abut to stopping member 59. The lip 68 (see FIGS. 15 through 20) gives
free the opening of the shaft 69 so that in the way discussed with
reference to the figures mentioned the key in the coin lock can be turned
and removed from the lock.
It should be explicitly noted that the variant according to the figs.
discussed here make the activation of the locking by means of e.g. a piece
of wood impossible. In absence of rotation of the roller 40 or a rotation
proceeded by a displacement, namely, no hooking cooperation takes place
between the hooking member 102 and the slide 106 through the recess 116
and the pin 114 respectively. Therefore by this cause no shifting of the
slide 106 takes place. Correspondingly the shaft 39 is blocked against
displacement and the key cannot be removed.
FIG. 35 shows that after trying to activate by means of e.g. a piece of
wood of the hook member 102 in case of rotating the roller 140 the hook
member 102 cannot be brought into hooking cooperation with the recess 116
on pin 114 of slide 106 afterwards. Such a hooking cooperation is, namely,
prevented by a cam 117 cooperating in the manner shown in FIG. 25 in the
situation with a pin 118 present on a swiveling arm 48.
Referring to the explanation hereinbefore it will be clear that the hooking
cooperating can only take place in case of a simultaneous rotation and
displacement into the left hand direction of roller 40, which in a normal
case only takes place in case a bicycle wheel is driven into the stand.
The invention is not limited to the embodiments shown and described. It
should be noted that the lock may be electrically remote-controllable.
This may be important for a barrier or a gate.
The bicycle stands embodying the invention may be disposed, as will be
apparent inter alia from FIG. 1, in the same manner as conventional
bicycle stands, for example, as single stands and they do not occupy more
space than the known stands.
In order to the destruction-proof character, if desired, the roller
cooperating with a wheel can be adapted for cooperation with a bicycle
tire in case of the variant according to FIGS. 28 through 35, whereto it
is provided with a rough surface or a surface provided with ribs, but on
the width of a rim without a tire is intentionally smooth, or even
preferably provided with a plurality of flat faces. By the lawless
introduction of a rim without a tire in this way it is achieved that the
rim cannot activate the activation roller but performs a slipping movement
relative thereto, so that the bicycle stand is not energized and the key
cannot be removed.
