Definitions

  • This invention relates to industrial lift trucks of the type having a telescoping upright mounted at the forward endthereof, and load carrier means mounted on a lift slide which is in turn mounted in tracks of the upright for vertical movement relative thereto, and more particularly it relates to a method and means for employing the load engaging means, such as fork tines, of industrial trucks so as to enable the load engaging means to be manipulated in an extremely novel manner from a position longitudinal of the truck to a position transverse thereof on either the right or left hand side of the truck.
  • Equipment for use with lift trucks has been previously constructed which makes it possible to pick up and deposit loads which are stacked or are to be deposited by the side of the lift truck.
  • a construction is known in which a plate is hinged with one of its vertical edges connected to the corresponding side edge of the lift slide (which is mounted for vertical movement in the upright), or adjacent to it, in such a manner that the plate can be rotated in a horizontal plane by pivoting same about its connection. to the side edge of the lift slide.
  • a second plate is hinged at its side edge in such a manner that it can likewise be rotated in a horizontal plane, but in the opposite direction.
  • On the second plate is normally mounted a pair of fork tines or other load engaging means.
  • Such construction allows the fork tines to be swung up to 90 to each side horizontally, in relation to the lift slide and upright. With such equipment the load may be picked up and/or deposited either to the right or to the left of the truck, as well as in the driving direction of the truck.
  • the load engaging means moves in a straightline, and therefore standard pallets can be used therewith; also, certain loads which can be picked up with standard fork lift .trucks without pallets can also be picked up without pallets with the above mentioned construction.
  • the load units can be taken from tightly stacked rows and can be likewise in: serted for deposit in a relatively small space in closely stacked rows.
  • the fork tines may be replaced by clamps or other load engaging means which can approach the load in a straight line, which is not possible with the first mentioned construction which is actuated to either side with a circular movement.
  • this load carrier construction is that it can be utilized only on one side of the truck, and can in no instance be utilized in the driving direction of the truck. If the truck is to be used for work on the opposite side, the load carrier must first be mounted on the opposite side of the boom. For instance, a load cannot be picked up on the right of the truck and deposited on the left thereof or in the driving direction. The picking up and depositing of loads must always be done in the same direction. Ob: viously, this is a considerable limitation on the useful ness of a truck which utilizes such a construction.
  • a load carrier which can execute straight-line lateral movements and can be also rotated from the lateral position, that is, it can lie-pivoted into the driving direction of the vehicle.
  • the load carrier is mounted on a single-arm swing lever which pivots on a vertical axis.
  • This lever can be pivoted by means of a hydraulic rotary slide; by means of a parallelogram guide arrangement it is forced to make a straight-line lateral movement when the load engaging means has been swung into the lateral position.
  • a load located, for instance, on the right beside the truck may be picked up and deposited-in a straight-line.
  • the load may also be picked up from that side, swung around 90- and deposited" in the driving direction of the stacking truck, or vice versa.

  • This latter load carrier has the disadvantage that no change of the working side from right to left or vice versa is possible, not even by remounting.
  • its. construction is very expensive and delicate, and is subject to rapid wear and high maintenance expense.
  • Such a load carrier also protrudes an impractical distance in frontof the lift upright of'the truck. Such protrusion results in greatly reducing the safe lift capacity of any given truck.
  • Lift trucks have also become known in which the entire upright structure of the truck can be pivoted by means of rotation of trunnion means located on the truck chassis, on which the upright is mounted. These are generally known as slewing-mast type trucks. Such trucks are of very special construction, because the work on the sidecannot be executed by a loadcarrier which can be mounted on any standard lift truck. The manufacturing costs. of such a truck are very high. In the use of such a truck inheres all the disadvantages of the first mentioned swinging load carrier construction.

  • the present invention intends to solve a special problem, that is, to use a standard industrial lift truck and simply attach to the lift slide a novel type of load carrier means with which all those transportation operations can be carried out which, with previously known constructions, could be carried out only in part.
  • the operations in question are principally the following:
  • the arrangement consists of two levers 2 and 3 which are hinged together and the free ends of which are hinged to guide members 4 and 5, respectively.
  • a load carriage 16 is hinged to the common joint of levers 2 and 3 and is adapted to swing horizontally.
  • the load engaging means comprises the usual pair of fork tines which are secured to the carriage 16 in known manner. All movements of the carriage are executed as a result of movement of the guide members 4 and 5 along a guide track 1.
  • Phase a of Figure 1 illustrates the load carrier in its basic position relative to the lift truck, in which position the truck can be utilized in a well known manner, as with the usual forwardly projecting fork tines.
  • the load carrier can be swung -.to the right via phase positions-a-e-f and from;.thc posh tion shown in phase 7 may be actuated in a straight-line transverse to the driving direction of the vehicle, as illustrated in movement phases c--d, but in an opposite sense thereto.

  • My invention is well adapted for use with such avehicle.
  • This vehicle is of a well known type and includes a body portion 52 which is mounted on four wheels in the usual manner.
  • An operators station is indicated generally at numeral 54, and includes a steering wheel for operating the rear wheels of the truck, an operators seat, and various controls, not shown, for operating the truck and the device of my invention which is associated therewith.
  • a vertically disposed telescopic mast structure is lo cated at the front end of the body portion of the truck and is indicated generally by numeral 56.
  • Mast structures of the general type indicated are known and need not be described in detail herein.
  • the mast structure 56 includes an outer guideway formed by a pair of channel members 58 and an inner slide member 60 which telescopes within the outer guide structure and which is formed by a pair of laterally spaced I-beams nested within the outer guide structure,
  • the plate member 18, to which the device of my invention is connected, is supported for vertical movement relative to the inner slide member 60 by means of a known bracket and roller assembly 62 associated with each one of the I-beam members of the inner slide structure.
  • a principal advantage of my invention lies in the fact that with one and the same lift truck, without any' remounting of the carrier and without the exchange of any parts, all stacking work which can possibly occur can be accomplished.
  • a lift truck which utilizes my device may work for days or hours as a standard lift truck, then as a swinging lift truck, and finally as a side shifting lift truck, either to the right or to the left or alternatingly to the right and the left and straight ahead. 7
  • the load carrier of this invention can be considerably simplified if it is to be used only as a universal transportation vehicle, without the requirement for remote control of the positions of the carriage 16.
  • the fork tines or other load engaging means are mounted about a vertical hinge or pivot connection of two levers which can swing horizontally in the hinge, and the opposite ends of which can likewise swing horizontally on guide members which are movable transversely to the driving direction of the vehicle.
  • the carriage 16 is equipped at both its upper and lower edges with :1 lug 9.
  • the two lugs 9 are hinged coaxially with the hinge 8 of levers 2 and 3, so that the carriage can swing in a horizontal plane about the axis of vertical hinge 8 at any desired elevation of the carriage relative to the tele scoping upright of the truckwhenever the levers 2and 3 have an enclosed angle less than
  • the levers 2 and 3 together essentially comprise a hinge having long flaps or sides which are connected at the adjacent ends thereof to the hinge joint 8.
  • levers 2 and 3 are hinged at 11 and 12 to the guide members 4 and 5 which are adapted to slide on, at or in the guide track 1 in a sliding or rolling manner and in a direction transverse to the longitudinal axis of the vehicle.
  • the levers 2 and 3 are hinged to the guide members 4 and 5 in such a manner that the swing axes of the two joints are aligned when the guide members are adjacent each other, as in Figure 4.
  • a construction must be provided such that in the transition from the basic position to the broken position of levers 2 and 3, the levers break toward the outside in a direction away from the guide track 1 and plate member 18 when the guide members 4 and 5 are brought together. i This can be accomplished, for example, by resting the joint 8 in the stretched position of the levers against a resilient member, not shown, on plate 18, which may comprise a simple leaf spring. By such an arrangement the joint 8 will be automatically broken in the proper direction when the guide members are brought together.
  • a construction also has the advantage that in the transition from a lateral position into the basic position, the carrier 16 will be brought to rest against a resilient member.
  • levers 2 and 3 In order to solve the problem under consideration, the levers 2 and 3 must have a fixed position when they are brought together to 0, and this may be obtained in a simple manner as shown in Figures 9a and 9b.
  • Each one of the two levers 2 and 3 has at its joint at the respective guide member, a lug 26 which rests against a surface of the respective guide member when the angle of 0 has been obtained. This construction allows the lever system to become rigid when in such position, as intended.
  • Each pin 23 is, for example, mounted on a lug 24 of the carriage 16 in such a manner-that when the carriage is in its basic position, the axis of each pin 23 is aligned with the joint axis of the respective guide member, as illustrated. The position of carriage 16 and of the fork tines is thus fixed.

  • Figure 6 is illustrated the above described locking means, which is located in the upper left hand corner of the carriage 16, as viewed from the operators station on the lift truck, whereas Figure 8 is a plan view of the device shown in Figure 6, and Figure 7 is a view in section along line 7--7 in Figure 6.
  • the embodiment of the locking or catch means as illustrated in Figures 6, 7 and 8 should be considered as exemplary only inasmuch as, for example, other means known to persons skilled in the art may be provided for making the pin 23 releasable under spring action.
  • the pin 23 in relation to lever arm 20 can be swung into the slot 22 under spring action within narrow limits.
  • the pin 23 is mounted on a swinging lever 25 which is under spring pressure and which protrudes through a slot in lug 24.
  • This arrangement may be sim plified by hinging the pin 23 directly to the carrier 16 with a spring actuated lever.
  • FIGs 9a and 9b there is illustrated a simple means for preventing any such undesired opening of the catch.
  • the catch lever 20 is mounted on the top of the left guide member 4 (as shown in Figure 7), and atop the guide member 5 is mounted astop member 27 which, when the guide members are adjacent each other, rests against lever 20 in such a manner that the lever cannot change its position even though the pull 15 acts on lever arm 20".
  • a similar device, not shown, is mounted at the lower portion of the guide member 4 which, in a corresponding manner, arrests movement of swing lever 20 at the underside of guide member 5, thereby preventing movement of guide member 5 when a pull is exerted thereon in the opposite direction.
  • the movement of the guide members can be accomplished in any desired manner by previously known means. It is not material in what manner the pull of member 15 is produced.
  • the power may be furnished by a suitably mounted double-acting hydraulic press, as has been previously done on known equipment, with a lateral sliding movement.
  • two such presses are provided at the plate 18, the one acting on the pull member 15 for guide member 4 and the other on the pull member 15 for guide member 5.
  • the two presses may be controlled by means of four valves combined into one bat; tery, each one controlling three paths.
  • Each one of the two chambers of each one of the two presses can be connected, as desired, to the pressure pump and to the discharge reservoir, and each chamber of one press can be connected to its other chamber, when the press is to run idle.
