Description

SPECIFICATION Lift truck This invention relates to a lift truck comprising a centrally disposed electric drive, two loadsupporting wheel or roller arrangements provided at the load end, and laterally disposed castet wheels, wherein the steering mechanism for the centrally arranged drive is or the caster wheels are resiliently mounted and batteries are mounted in the chassis of the vehicle.
The lift truck comprising two load-supporting wheel arrangements and a centrally arranged drive generally comprises a driven wheel, which is mounted on a drive subassembly, and the latter is movable together with the driven wheel about a vertical axis so as to steer the vehicle. Steering is preferably effected by means of a steering handle, the provision of which is included within the scope of the invention.
In another embodiment, which is also included within the scope of the invention, the caster wheels are vertically fixed to ensure a continuous ground contact, and a continuous ground contact of the driven wheel of the centrally disposed drive is ensured in that the steering mechanism of the centrally disposed drive is resiliently mounted. In that case the spring pressure can be adjusted to define a predetermined normal force exerted by the driven wheel. This embodiment is preferred within the scope of the invention.
The batteries are provided within the chassis of the vehicle particularly on both sides thereof and confine the drive subassembly of the vehicle so that said subsassembly together with the steering mechanism is accessible only with difficulty and the batteries must be removed when that subassembly is to be serviced as well as for servicing or replacing the batteries. In view of the heavy weight of the batteries, they can be removed only with difficulty and by means of expensive implements.
For this reason it is an object of the ivn so to improve a lift truck of the kind described first hereinbefore that the drive subsassembly and/or the batteries can be more easily serviced and the replacement of the batteries is facilitated.
This object is accomplished according to the invention in that at least one caster wheel is mounted on one battery carrier, which is adapted to be moved out of the chassis of the vehicle while guide means of the battery carrier remain in engagement with the chassis of the vehicle. In a preferred embodiment, battery carriers are provided on both sides for the batteries disposed on respective sides.
In a particularly preferred embodiment, the caster wheels are rigidly mounted on battery carriers provided on both sides of the chassis of the vehicle.
In such an arrangement the batteries can be moved out of the chassis of the vehicle without need for moved out of the chassis of the vehicle without need for additional implements and while the lift truck remains stably supported on its wheels. These advantages are not only afforded in connection with service work but the lift truck will also be stably supported during a replacement of the steering mechanism and the replacement of worn supporting caster wheels will be facilitated.
The carriers suitably comprise at least a bottom structure on which the caster wheels are mounted.
Within the scope of the invention, said bottom structures may constitute externally closed side portions of the vehicle when the carriers have been retracted.
In a preferred embodiment the carriers are adapted to be swung out about vertical hinges.
Because the carriers are supported on the ground, these hinges need not be very strong as they do not carry the batteries. The carriers preferably comprise a doorlike wall member, which is closed when the carriers have been retracted, and the hinge is provided at one end of said doorlike wall member.
In another desirable embodiment the carriers are movable along a telescopic guide, which extends along or transversely to the longitudinal direction of the chassis, the carriers can be extended like drawers and an abutment is provided for limiting the extent to which the carriers can be extended.
Roller-carrying telescopic rails are preferably provided so that the span in the longitudinal direction of the vehicle or transversely thereto will be increased when the carriers are extended. One form or the other can be used in dependence on local conditions.
In the last-mentioned embodiment, the roller guides are preferably provided on the chassis of the vehicle and extend particularly transversely to the longitudinal direction of the vehicle and the carriers are provided with roller-carrying telescopic rails, which are mounted on the roller guides.
In another suitable embodiment, roller-carrying telescopic rails are mounted on the two carriers and spaced apart in the longitudinal direction of the vehicle and juxtaposed roller guides are provided in the chassis of the vehicle.
A particularly preferred feature which is applicable to all embodiments resides in the provision of locking means which are mounted on the carriers and serve to rigidly lock the retracted carriers to the chassis of the vehicle. As a result, the retracted carriers are virtually integral with the chassis of the vehicle. This will be desirable for ensuring the defined ground contact of the vertically fixed casters.
The locking means may comprise vertical pins, which are adapted to be inserted into aligned openings formed in the relatively movable parts. In a particularly preferred embodiment, inclined run-up surfaces are provided, which rigidly lock the retracted carriers in the chassis of the vehicle in a predetermined elevation. Even when there is a certain backlash in the means by which the carriers are pivoted or connected to the chassis of the vehicle, such backlash will be eliminated when the carriers have been retracted, particularly in conjunction with the action of the locking means.
The invention will now be explained with reference to illustrative embodiments shown on the accompanying drawing, in which Figure 1 is a diagrammatic perspective view showing a lift truck embodying the invention, Figure 2 is a diagrammatic end view showing the lift truck as viewed from its steering end, Figure 3 is a fragmentary top plan view related to Figure 2, Figure 4 is a fragmentary top plan view showing another embodiment of the lift truck and Figure is also a fragmentary top plan view showing an embodiment of a lift truck.
In all Figures of the drawings, like parts are designated with the same reference characters. The lift truck 1 comprises an end chassis 2, which has a fixed central portion 3, in which a steering mechanism 4 is mounted for rotation about a vertical axis.
An electric drive motor and a steerable driven wheel 5 disposed below the drive motor and constituting a centrally disposed drive are connected to the steering mechanism 4. Such steering mechanisms are known per se and are mounted in the fixed central part 3 by means of at least one swivel bearing end, if desired, by means, not shown, which are vertically resilient. The steering mechanism is connected by a post 6 to a steering handle 7, which is provided at its free end with a controi head 8. The latter is provided with handles 10,11 and with levers 12,13 for controlling the steering mechanism. The control lines extend through the steering handle 7 and the axle 6.
Two prongs 14,15 are carried by the lift truck and extend opposite to the steering handle 7. Two load wheel sets 16, 17 are provided under the rear ends of said prongs and in the embodiment shown in Figure 1 consist of twin rollers.
In such an embodiment shown in Figure 1 the load wheel sets 16, 17 consisting of load-supporting twin rollers are rotatably mounted on axles which are fixed in the prongs 14, 15.
In the embodiment shown in Figures 2 to 5, prongs 18,19 are fixed to the lift truck and load-supporting wheels 20,21 are mounted in known manner, not shown, and are pivotally movable by means of levers, as is apparent, e.g., from German Early Disclosure 23 18048.
The chassis 2 of the vehicle is provided on opposite sides of the fixed central portion with lateral spaces 23,24 for accommodating batteries 25,26. Said lateral spaces accommodate battery carriers 27, 28, 29,30,31,32, which are extensible to protrude from the contour of the chassis 2 of the vehicle. Each battery carrier comprises at least a bottom structure 33, 34,35,36,37 or 38, on which caster wheels 39,40 rotatably mounted on fixed axes in the present embodiment, in which the steering mechanism 4 is resiliently mounted.
In accordance with Figures 1 and 3 the battery carriers 27,28 are provided with doorlike wall members, which when the carriers have been retracted constitute outer side walls of the chassis of the vehicle. Vertical hinges 43,44 are mounted at one edge of said doorlike wall members, e.g., on an upright. The carriers 27, 28 are laterally pivotally movable in an outward direction about said hinges, as is shown in Figures 1 and 3. During such outward pivotal movement the caster wheels 39,40 are carried along while they automatically adjust them- selves to their direction of travel and while maintaining the lift truck stably supported carry the load of the battery carriers 27,28 as well as the batteries carried thereby.It is apparent that in all embodiments shown the caster wheels 39,40 are arranged substantially in the central region of the length of the vehicle when the battery carriers have been retracted. To ensure a stable support of the lift truck in said condition the caster wheels 39,40 are disposed near the outer edge of the bottom structure 33,34. It is apparent that the pivotal axes of the caster wheels 39,40 lie approximately in the same transverse plane as the steering axis of the steering mechanism 4 when the battery carriers have been retracted.
It is apparent from Figure 1 that the lateral spaces 23,24 for accommodating the batteries, for instance, the space 26 in Figure 1, can be closed at the top by a hinged cover 45, which has a forward flange 46 that is adapted to be flush with the doorlike wall portion 42 or to interengage therewith, if desired. A locking device for that purpose is shown in Figure 1 and comprises a pin 47 carried by the hinged cover 45 and an associated opening 66 defined by a bushing on the doorlike side wall portion 42. This arrangement permits a very simple locking, provided that the hinge 43,44 has virtually no vertical backlash.
In the embodiments shown in Figures 4 and 5, the batter carriers 29,30,31,32 are movable out of the chassis 2 of the vehicle by roller-carrying telescopic rails 48 to 51,60,61. The battery carriers 31,32 are movable in the longitudinal direction of the chassis 2 and the battery carriers 29,30 are movable transversely thereto.
In the embodiments shown in Figures 4 and 5, the battery carriers are provided, e.g., with outer wall members 68,69, which close the chassis of the vehicle on the sides when the carriers have been retracted.
Locking means, which may be combined with a hinged cover and have been indicated at 47 and 66 in Figure 1, are shown in Figures 4 and 5 at 47,66 and 47', 66', respectively. It will be understood that particularly where roller-carrying telescopic rails or overlapping parts are used, the guides may be provided with run-up surfaces, not shown, in order to eliminate any backlash between the relatively movable parts. Such run-up surfaces may consist of inclined surfaces which engage each other when the battery carriers have been retracted and locked.
