Description
BACKGROUND OF THE INVENTION
This invention relates to a toy representing a building inside
which is a shaft in which is a lift or elevator for raising the
vehicles from the lower level to the higher level end of a
descending track between an exit from the shaft at one end of the
track to an entrance into the shaft at the other end of the track,
along which toy vehicles, such as toy motor cars, may roll and
wherein a catch combined with an advance action catch is provided
for intercepting the vehicles arriving at the entrance.
In a toy of the specified kind already known in the art the toy
vehicles are raised by the lift from the entrance into the shaft to
the exit from the shaft. At the entrance into the shaft a catch
associated with an advance action catch for intercepting the
arriving vehicle is provided, whereas at the exit there is a catch
for retaining the outgoing vehicle until it is released by the
following vehicle. The purpose of these intercepting catches is to
retain each vehicle in the shaft until the next vehicle has entered
the shaft and reached the exit. In this arrangement the vehicles
all enter the shaft and leave the shaft in the same consecutive
order. This does not in fact conform with what actually happens for
instance in a real multistory car park.
SUMMARY OF THE INVENTION
The present invention provides novel means for selectively
positioning the toy vehicles into parking bays provided in a
representation of a multistory car park and for selectively
removing such toy vehicles from the parking bays.
According to the present invention this is achieved by making
provision for the toy vehicles to be raised by the lift above the
level of the exit, and possibly also to be lowered below the level
of the entrance, for selectably transferring them into and
collecting them from parking bays at levels above the exit, or
below, the entrance.
It is an object of the present invention, for the benefit of the
playing child, to provide facilities for changing the sequence of
incoming and outgoing vehicles and to retain the vehicles in the
"car park" for as long as may be desired.
In a particularly convenient embodiment the lift may be raisable
and lowerable by a motor-driven coiled spring. This will then
permit the lift to be raised and lowered through considerable
distances. The driving motor may be an electric or a clockwork
motor.
In order to raise or lower the lift, as may be required, a
reversing gear may be interposed between the driving motor and the
coiled spring, the reversing gear being operable by a lever for
reversing the direction of rotation of the coiled spring. This
eliminates the need for a reversible driving motor.
Preferably the reversing gear comprises a crown wheel driven by a
worm and adapted to be selectably brought into engagement with
either of two spur wheels mounted on a drive shaft for the coiled
spring.
It is further preferred to attach a normally nonrotating toothed
wheel to the lift for cooperation with the coiled spring in order
to raise and lower the lift. However, the toothed wheel is
preferably merely prevented from rotating by a friction clutch.
This means that the toothed wheel is in fact capable of rotating to
permit continued rotation of the coiled spring in the event of the
lift striking and being retained by an obstacle. Conveniently the
friction clutch may simply be constituted by a spring adapted to
urge the toothed wheel into frictional contact with a surface on
the lift.
According to another feature of the invention, the vehicles may be
transferable from the lift into the parking bays and from the
parking bays into the lift by the floor of the lift and the floors
of the parking bays being tiltable in opposite directions. In a
preferred arrangement of this kind the floor of the lift may be
tiltable about a horizontal axis located adjacent a vertical wall
of the lift near its front end when viewed in the direction of
vehicle travel, while the floors of the parking bays are tiltable
about horizontal axes located at the rear end of the floor when
viewed in the direction of vehicle travel.
For tilting the floor of the lift and the floors of the parking
bays, a manually operable cranked lever may be rocked into
cooperation either with the underside of the floor of the lift or
of the floor of a parking bay. For cooperation with the cranked
lever the floor of the lift may be provided with a downward
projection.
Moreover, by associating with each parking bay, with the exception
of the highest and the lowest level bays, a manually controllable
stop it is possible to ensure that the lift will always be stopped
in correct position for unloading or loading a vehicle. Preferably
a counterstop on the lift may be arranged to cooperate with the
controllable stop.
In a particularly convenient arrangement the stop may be formed by
the angled end of an actuating lever, whereas the counterstop is an
angled extension of the backwall of the lift. Preferably stop and
counterstop are thin section elements, since this will permit the
same controllable stop to be used for stopping the ascending as
well as the descending lift at substantially the same level.
For limiting the tilt of the floors of the parking bays there may
be associated with each floor a projection from the wall of the
shaft.
According to another feature of the invention, the toy vehicles may
have a laterally projecting stop which cooperates with a stop on
the backwall of the lift when the floor of the lift is tilted
contrary to the slope of the track, said stop of the backwall being
nonobstructive, when the floor is tilted in the direction
corresponding with the slope of the track. This prevents the
vehicles from accidentally rolling off the floor of the lift.
The stop on the toy vehicle may conveniently consist of an
extension of one of the vehicle axles beyond the side of the
vehicle.
In order to ensure appropriate slope of the floor of the lift at
the entrance, the latter may be provided with a supporting fillet
for cooperation with the floor of the lift.
The catch at the entrance preferably has the form of a
hand-operable lever of a kind which is known in the art, and which
has two intercepting lugs which alternately project upwards through
the track.
The interest of the child in the toy may be further increased by
the provision of a further catch for intercepting the vehicles on
the track outside the building which may represent a multistory car
park, said catch being releasable by the arrival of the following
vehicle. The catch may preferably be associated with an imitation
building, such as a carwashing bay. The arrangement will then
operate for a short time to retain the vehicles travelling down the
track from the exit to the entrance in the "carwashing bay."
The catch inside the imitation building may consist of a two-armed
lever tiltable on an VI traverse to the track and having two arms
extending in the direction of the track, one of said arms carrying
a stop face for intercepting a toy vehicle, but being tiltable into
a release position by a following vehicle which strikes the other
end of the lever arm. In such an arrangement the catch may
conveniently cooperate with a stop on the roof of the toy vehicle.
This stop on the roof of the vehicle preferably consists of an
outward indentation formed with a forward-facing vertical edge. To
facilitate the release of the catch by the following vehicle the
end of the lever arm which causes the catch to release may with
advantage be provided with an arched ramplike surface for
cooperation with the arriving vehicle. The leading vehicle will not
then be released until the next vehicle has entered the imitation
building and lifted the catch.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
Mounted on a base 2 formed with a track 1 is a multistory car park
building 3 as well as a simulated carwashing bay building 4, The
track 1 descends from a more elevated exit 5 from the car park to a
lower level entrance 6. Owing to the downward gradient of the track
1 the vehicles 7 will roll down the track without requiring drive
means. Outside the entrance 6 there is provided in the track an and
intercepting catch 8 combined with an advance action catch for the
vehicles 7.
Inside the car park building 3 several parking bays 10 are provided
above the floor 9 of the exit 5, which slopes downwards in the
direction of travel. The vehicles 7 can be raised by a lift or
elevator 11 from the level of the entrance 6 to the level of the
exit 5 or further raised or lowered to and from one of the several
parking bays 10.
For operating the lift 11 a coil spring 12 embraces one leg 13 of a
U-shaped rod 14 vertically mounted inside the car park 3. The leg
13 of the rod 14 is shorter than the other leg 43 which also serves
for locating the U-shaped rod 14 in the car park 3. The end 15 of
the coil spring 12 which extends beyond the end of the leg 13 is
attached to a drive shaft 16 carrying two spur wheels 17, 17' which
can be selectably shifted into engagement with a crown wheel 18
driven by a worm 19 on the shaft of an electric motor 20.
Engagement of the spur wheels 17, 17' is effected by means of a
hand lever 22 (FIG. 3) projecting to the outside through a slot 21
in the wall of the car park building 3. This arrangement permits
the direction of rotation of the coil spring 12 to be reversed
without reversing the motor 20. The batteries for the motor 20 are
housed in a contained 23 which is accessible through a flap 25 in
the roof 24 of the car park 3. The flap 25 for closing the
container 23 also carries a switch 26 for controlling the motor
20.
The coil spring 12 cooperates with a toothed wheel 28 on the
backwall 27 of the lift 11 (FIG. 6). The toothed wheel 28 is urged
by a spring 29 into frictional contact with the backwall 27 of the
lift so that normally this wheel will not rotate. However, the
wheel can rotate when the lift 11 is kept stationary. This prevents
the coil spring from being blocked and protects the motor 20 from
being damaged.
Projecting from the vertical backwall 27 of the lift 11 is a
substantially horizontal platform 30 which has an upright edge 31
remote from the back. This edge 31 and the backwall 27 are each
provided with a hole 32 in which pins 34,34' projecting from the
tiltable floor 33 of the lift 11 respectively engage. The tiltable
floor 33 has a downward projection 35 which passes through the
platform 30, as well as a stop 36 near its rear edge as viewed in
the direction of travel. This stop 36 bears against the floor 37 of
the car park 3 when the lift is in its bottom position indicated by
dot-dash lines in FIG. 3, thus ensuring that the floor 33 of the
lift is substantially horizontal.
The side of the backwall 27 of the lift 11 facing away from the
tiltable floor 33 carries a guide plate 38. This guide plate 38 is
formed with two sleeves 39, 39' which embrace and guide the coil
spring 12. An abutment face 40 provides purchase for the
compression spring 29 which bears against the toothed wheel 28. The
free edge 41 of the guide plate 38 has two substantially horizontal
lugs 42, 42' provided with holes through which the other leg 43 of
the U-shaped rod 14 passes. The described arrangement guides the
lift 41 reliably both in the horizontal and in the vertical
direction.
The parking bays 10, 10' have tiltable floors 44, and 44'. The rear
ends of these floors 44, 44' in the direction of travel, hinge on
cranked shafts 45.sup.2 and 45 which pass through holes in the wall
of the car park building 3. The tilt of the floor 44 is limited by
stops 46 and 46' formed by portions bent out of the wall 47 of the
car park building 3 while the tilt of the floor 44' is limited by
similar stops 46.sup.2, 46.sup.3 similarly formed.
The cranked shafts 45 and 45.sub.2 serve for tilting the floors 44,
44' of the parking bays 10, 10' and also for tilting the floor 33
of the lift 11. By turning one of the knobs 48, 48' or 48.sup.2 on
the ends respectively of the cranked shafts 45.sub.2, 45 and 45'
outside the wall of the car park 3 the cranked part of the
respective cranked shaft can be swung into engagement either with
the underside of the floor of its parking bay or the projection 35
of the tiltable floor 33 of the lift 11. This permits such floors
to be tilted into the positions indicated in dashed lines in FIG.
3. The floor 9 at the exit 5 is mounted similarly to the floors 44,
44' and tilting is prevented by a stop 50 (similar to the stops
46', 46.sup.2) so that operation of the cranked lever 45' at this
level permits only the floor 33 of the lift 11 to be tilted.
Associated with the parking bay 10' and also with the exit 5 are
controllable stops 51, 51', which determine the positions in which
the lift 11 stops, but a stop 52 associated with the highest level
parking bay 10 is fixed. These stops 51, 51' and 52 cooperate with
a counterstop 53 (FIG. 3) on the backwall 27 of the lift 11. The
stops 51, 51' are angled extensions of respectively operating
levers 54, 54' which have hand-operable ends 55, 55' projecting
through one wall of the car park building 3 to the outside. The
counterstop 53 on the lift 11 is formed by an angled lug formed on
the backwall 27. The stops 51, 51' and the counterstop 53 are thin
sections elements preferably consisting of sheet metal.
In order to prevent a vehicle on the floor 33 of the lift 11 from
rolling backwards when the floor 33 is tilted contrary to the slope
of the track 1 (as in the full line showing in FIG. 3), the
backwall 27 is provided with a retainer 56 which projects in the
direction towards the floor 33, for cooperation with an extension
57 of the rear axle of the vehicle 7 beyond its sidewall. However,
when the lift 11 is in the lowermost position shown in dot-dash
outlines in FIG. 3, then the floor 33 is sufficiently raised to
ensure that the portion of the stop 56 projecting above the floor
will not obstruct the axle extension 57 of the entering vehicle
7.
The intercepting catch 8 at the entrance 6 has the form of a
two-armed rockable lever 59 which is held in position by bentover
lugs 58 passed through the base 2. The rockable lever 59 comprises
two intercepting lugs 60, 61 of which either one can project from
the track 1 to intercept a vehicle 7. The lever is operable by a
finger rest 62 (FIG. 2).
Substantially halfway down the track 1 is the simulated "car wash"
building 4 and inside this building is another intercepting catch
63 for the toy vehicles 7. This catch releases an intercepted
vehicle 7 when the next vehicle arrives. The catch has the form of
a double-armed lever which is deflectably mounted across the width
of the track 1 (of FIG. 8). The front end of the lever 63 in the
direction of travel of the vehicles 7 carries an intercepting lug
in the form of an angle member 64 for cooperation with a stop 65 on
the roof of the vehicles 7. The stop 65 on the roof of the vehicles
7 is formed by an outward indentation which has a substantially
vertical front face 66 (FIG. 7). The rear end of the lever 63 is
formed with a sloping face 67 forming an inverted ramp.
THE DESCRIBED TOY FUNCTIONS AS FOLLOWS
When the lift 11 is in the lowermost position, indicated in FIG. 3
by a dot-dash outline, the finger rest 62 may be depressed to lower
the retaining lug 60 of the entry catch 8 and thereby allow a
stationary vehicle 7 to roll forward onto the floor 33 of the lift
11. The forward motion of the vehicle is stopped by a vertical wall
68 formed by the base 2. When the retaining lug 60 descends the
other retaining lug 61 simultaneously rises to stop any further
vehicles 7 which may be approaching or waiting outside the entrance
6. When the finger rest 62 is released the intercepting catch 8
returns into its former lowered position shown in FIG. 3, allowing
any waiting vehicle outside the entrance 6 to advance to the second
retaining lug 60.
When the vehicle 7 has rolled onto the floor of the lift 11, the
motor 20 is started by operating the switch 26, and the lever 22 is
raised. The coil spring 12 will then begin to rotate and raise the
lift 11 by cooperating with the toothed wheel 28. The lift 11
continues to ascend until its counterstop 53 is intercepted for
instance by the stop 51. If the cranked shaft 45 is now tilted, as
indicated by the arrow 69, it will strike the projection 35 under
the floor 33 of the lift, thereby tilting the floor into the dotted
position in FIG. 3 and thus permitting the vehicle 7 to roll down
the floor 9 and out through the exit 5 onto the track 1. However,
if the stop 51 has been deflected out of range of the counterstop
53, the lift 11 will continue to ascend until the counterstop 53
strikes the stop 51' or stop 52, when the deflection of the
associated cranked shaft 45 or 45.sup.2 will permit transfer of a
vehicle 7 into one of the parking bays 10, 10'.
Assuming that it is now desired to move a vehicle parked in the
parking bay 10' to the exit 5, this is done by deflecting the stop
51' into range of the counterstop 53 by operating the arm 55',
thereby bringing the lift 11 to a stop at the level of this parking
bay 10'. By then deflecting the cranked shaft 45, in the direction
opposite to that indicated by the arrow 69, the floor 44' of the
parking bay 10' can be tilted so that the parked vehicle 7 will
roll back onto the floor 33 of the lift 11. The stop 51 is now
deflected into the path of the counterstop 53. By then depressing
the lever 22 the rotation of the coil spring 12 is reversed and the
lift 11 therefore descends until the counterstop 53 strikes the
stop 51, this being the position illustrated in full lines in FIG.
3. In the manner that has already been described the vehicle can
now be released by operation of the shaft 45' to leave through the
exit of the car park.
If the lift 11 is desired neither to ascend nor to descend, the
lever 22 need merely be placed in a position in which neither of
the two spur wheels 17 meshes with the crown wheel 18.
In the described car park the vehicles 7 can therefore be parked in
the parking bays 10 in any desired sequence or they can be
recovered from the bays and allowed to leave the car park as may be
desired. The toy therefore reproduces every aspect of the operation
of a real multistory car park.
When the vehicle 7 has left by the exit 5 it will roll down the
track 1 until it reaches the car washing bay 4 wherein it is
intercepted by the lug 64 of the lever 63. When the next vehicle
reaches the washing bay 4 the stop face 65 strikes the sloping
underside 67 of the lever 63, tilting the lever and thereby
releasing the first vehicle 7 in the washing bay. At the same time
the arriving vehicle 7 is intercepted by the lug 64.
Naturally the parking bays 10 need not necessarily be at elevations
above the floor 9 of the exit. they might also be at levels below
the floor 9, in which case the elevating height of the lift 11
would have to be extended accordingly.
