INVENTOR. BYRON F. BOONE United States Patent 3,486 ,650 HEAVY MOVER APPARATUS Byron F. Boone, 100 S. 160th E., Wichita, Kans. 67230 Filed Apr. 8, 1968, Ser. No. 719,527 Int. Cl. B60p 1/02 U.S. Cl. 214-390 6 Claims ABSTRACT OF THE DISCLOSURE Numerous types of article handling devices are known to the prior art attachable to a large object through interconected belt and strap members to be moved through a frame structure. However, the prior art devices are generally difficult to attach to a heavy article to be moved and merely operate to elevate the article abovethe supporting surface on wheel caster devices and, therefore, elevate the article to be conveyed a predetermined fixed distance. It is also noted that the prior art devices are generally limited in the height to which the conveyed articles may be elevated above the supporting surface.
In one preferred embodiment of the mover apparatus of this invention, generally used in pairs to move a heavy object, the same includes connector and lift means attachable to the article to be conveyed and connected through jack means to an upright support means. The connector and lift means includes a basic frame means having an attachment assembly connectible to the object to be moved. The frame means includes a pair of spaced, parallel support frame assemblies interconnected at the forward sides by the attachment assembly. Each support frame assembly includes a pair of upright spaced main tube members interconected by horizontally extended parallel support struts and having anchor assemblies connected thereto. Mounted within the forward tube members are upright auxiliary support posts operable to be moved axially therewithin and held in a desired position as by the anchor assemblies. The attachment assembly is provided with an inverted U-shaped stabilizer member having lower leg portions connected to an L-shaped support bed. The upper area of the leg portions are interconnected by a guard bar adapted to abut the article to be moved. The support means includes a pair of spaced support shafts interconnected as by a support strut at the lower ends thereof which, in turn, are respectively connected to swivel assemblies for easy movement of the entire structure. The support shafts are telescopingly mounted within the rearward tube members of the support frame assemblies and operable to be connected by anchor assemblies to the tube members so as to provide the desired vertical adjustment relative thereto. The jack means includes an upright actuator shaft connected to a support base and an actuator mechanism connected to the shaft and the support bed of the connector and lift means. The actuator mechanism is provided with a jack handle operable in conjunction with the actuator shaft to move the connector and lift means and an object carried thereon to the desired height. Additionally, a winch assembly is mounted upon one of the end frame assemblies having a rotatable cylindrical drum receiving a strap member whereby the strap member is connectible to another cooperating mover apparatus to hold the article to be moved therebetween.
One object of this invention is to provide a mover apparatus overcoming the above-mentioned disadvantages of the prior art structures.
A still further object of this invention is to provide a mover apparatus operable with a minimum clearance with a supporting surface having jack means operable to raise and lower a load thereon as desired.
Another object of this invention is to provide a mover apparatus, preferably usable in pairs for attachment to an object to be conveyed, including a support means secured to a connector and lift means by a jack means whereupon the object conveyed can be moved vertically as desired by the jack means in order to pass through restricted areas and, additionally, to raise a heavy article to an elevated position for loading purposes.
One other object of this invention is to provide a mover apparatus that is rigid in construction, easy to use, economical to manufacture, and requiring a minimum of maintenance.
Various other objects, advantages and features of the invention will become apparent to those skilled in the art from the following discussion, taken in conjunction with accompanying drawings, in which:
FIG. 1 is a perspective view of the pair of the mover apparatus of this invention connected to an object illustrated in dotted lines to be moved;
FIG. 2. is a rear elevational view of the mover apparatus of this invention;
FIG. 3 is a side elevational view of the mover apparatus of this invention;
FIG. 4 is an enlarged elevational view of an anchor assembly of the mover apparatus of this invention having portions thereof broken away for clarity;
FIG. 5 is an enlarged fragmentary top plan view of the winch means of the mover apparatus of this invention; and FIGS. 6, 7, and 8 are schematic diagrams illustrating the use and operation of the mover apparatus of this invention.
The following is a discussion and descripiton of preferred specific embodiments of the new mover apparatus of this invention, such being made with reference to the drawings, whereupon the same reference numerals are used to indicate the same or similar parts and/or structures. It is to be understood that such discussion and description is not to unduly limit the scope of the invention.
Referring to the drawings in detail and particularly to FIG. 1, a pair of the mover apparatus of this invention, indicated generally at 12, are shown as interconnected having a large object such as a rectangular box 14 mounted threbetween in a clamped relationship. Although the mover apparatus 12 has been illustrated as using a pair to lift and move the rectangular box 14, it is obvious that a plurality of these devices could be attached to a common large object if required to provide the necessary load bearing support thereto. Each mover apparatus 12 includes a connector and lift means 16 slidably mounted upon a support means 18 and interconnected therebetween by a jack means 20 for relative movement.
The connector and lift means 16 includes a basic frame means 22 having an object attachment assembly 23 secured thereto. The basic frame means 22 includes a pair of spaced end support assemblies 26 and 28 interconnected through the jack means 20 and the attachment assembly 23 as will be explained. As each end support assembly is identical, only one need be described in detail. As shown in FIGS. 1 and 3, the end support assembly 28 is provided with front and rear upright elongated tube members 30 and 32 interconnected by horizontally extended support struts 34 which may be of a pipe material or the like. The front tube members 30 are provided with elongated auxiliary support posts 36 telescopingly mounted therein and securable in adjusted axial position as by anchor asemblies 38. The support posts 36 are provided with a plurality of equally spaced holes 40 operable to be selectively placed in locking engagement with the respective anchor assembly 38 as will be explained. The rear tube members 32 are also provided with anchor assemblies 38 for reasons to become obvious.
Only the end support assembly 28 is provided with a winch assembly 41 secured between the front and rear tube members 30 and 32 and the lowermost one of the horizontal support struts 34. As shown in FIG. 5, the winch assembly 41 includes a cylindrical drum member 43 rotatably mounted between a pair of spaced triangular gusset plates 45 which are secured as by welding to the end support assembly 28. A handle member 46 is connected to the cylindrical drum member 43 for assembly 47 is provided whereupon the cylindrical drum 43 is automatically latched on rotation in one direction and must be positively released before movement in the other direction. Additionally, the winch assembly 41 includes an elongated belt member 49 having one end connected to and trained about the cylindrical drum member 43, and the other end of the belt member 49 is provided with a J -shaped metal clamp member 51 engageable with the rear tube member 32 on mating mover apparatus 12 as will be explained.
The attachment assembly 23 is provided with a U- shaped stabilizer member 54 having upright parallel legs 56 secured as by welding to the inner facing surfaces of the front tube members 30 on the end support assemblies 26 and 28 with the lower ends of the legs 56 secured to a support bed 57. The upper ends of the legs 56 are interconnected by a guard bar 58 which provides a sock absorbing feature preferably constructed of wood engageable with the rectangular box 14 to maintain solid contact therewith. The support bed 57 is of generally L- shape in transverse cross section and secured as by welding on the back surface thereof to the legs 56. The support bed 57 is preferably constructed of a heavy gauge steel material; however, any material can be used providing sufiicient strength for carrying heavy objects.
The support means 18 includes a pair of parallel upright support shafts 61 having their respective lower ends connected to swivel assemblies 62 and additionally interconnected by a transverse support strut 64. The upright shafts 61 are spaced a predetermined distance by the support strut 64 so as to be mountable in telescopingly relationship in respective ones of the rear tube members 32 on the end support assemblies 26 and 28. Each support shaft 61 is provided with a plurality of equally spaced holes 65 adapted to be engageable with a locking feature of the anchor assemblies 38 mounted on the rear tube members 32 as will be explained. Each swivel assembly 62 is provided with a U-shaped support body 67 pivotally connected at the upper end thereof to the respective support shaft 61. The lower ends of the support bodies 67 are each adapted to receive a shaft 68 having a wheel member 69 rotatably mounted thereon. The swivel assemblies 62 are of a generally conventional caster wheel type operable to maintain ease of movement while supporting a large load thereon. It is seen that the basic frame means 22 is movable in a generally vertical direction relative to the interconnected support shafts 61 of the support means 18.
The jack means 20 includes a laterally extending base member 71 having an upright actuator shaft 73 thereon mounted on a base bar 75 and an actuator mechanism 76 conn c d o h ha t 3 and also to the support bed 57 of the basic frame means 22. The base bar 75 is provided with an elongated main body 78 having tubular stub members 80 welded to opposite ends thereof each mounted about the respective support shafts 61 between the respective swivel assemblies 62 and the lower ends of the rear tube members 32 on the end support assemblies 26 and 28. One of the anchor assemblies 38 is attached to each of the tubular stub members 80 and engageable with the respective support shafts 61 as will be explained. The actuator mechanism 76 is secured as by welding or the like in a rigid manner to the support bed 57 with the actuator shaft 73 mounted therethrough engageable with a laterally extended actuator handle 81. The actuator mechanism 76 is given additional rigidit by support rods 83 welded thereto extended to the lower ends of the rear tube members 32 of the end support assemblies 26 and 28. The operation of the jack means 20 is substantially identical to conventional automotive jacks; therefore, a detailed description of the operating mechanism is not deemed necessary. It is obvious that the handle 81 is movable in a vertical plane through a pumping movement to raise and lower the connector and lift means 16.
As shown in FIG. 4, each of the anchor assemblies 38 includes a cylindrical housing 84 welded to the respective ones of the front and rear tube members 30 and 32 and the cylindrical stub members 80 and having a T- handle 86 connected thereto. The T-handle 86 includes a grasp end portion 87 integral with an elongated lock shaft 88 extended through an opening 90 in a cap member 92 into a cylindrical bore 93 within the housing 84. The lock shaft 88 is provided with a lug portion 94 having a compression spring 95 mounted thereabout engageable with a stepped portion 97 and the cap member 92. The spring 95 biases the T-handle 86 inwardly through an aligned hole 99 in the respective member mounted thereon to be engageable with the aforementioned spaced holes in the respective support shafts 61 and auxiliary support posts 36. It is obvious that the T-handle 86 may be pulled to the left, as viewed in FIG. 4, to release the lock shaft 88 from the respective holes for axial movement. The compression spring 95 normally biases the entire T-handle 86 inwardly to the locked position and gives a positive indication of the secured position to prevent use of the mover apparatus 12 without properly locking all the required elements. Also, the lock shaft 88 may be provided with a laterally extended detent (not shown) .movable in a slot in the housing 84 so as to latch the shaft 88 in the unlocked position for ease of usage.
In the use and operation of the mover apparatus 12 of this invention, it is seen that the jack means 20 can be lowered downwardly into abutting engagement of the stub members 80 with the respective swivel assemblies 62 by release of the anchor assemblies connected thereto. The. jack means 20 can be actuated through the actuator handle 81 and moved to the lowermost position to place the entire connector and lift means 16 adjacent a supporting surface as shown in FIG. 6. In this position, it is seen that the support bed 57 is easily movable laterally to a position underneath an object to be moved such as therectangular box 14. The belt members 49 from the respective winch assemblies 41 are thereupon trained about the adjacent end support assembly 28 and connected to the rear tube member 32 of another cooperating mover apparatus 12 through the clamp member 51 as shown in FIG. 1. The handle member 46 of the winch assembly 41 can be rotated so as to pull the respective mover apparatus 12 into snug cooperating engagement with the rectangular box 14 to be moved.
. Next, the jack means 20 can be operated through the actuator handle 81 to raise the interconnected connector and lift means 16 upwardly by axial movement on the shaft 73. It is obvious that during this moving operation the anchor assemblies 38 on the respective rear tube members 32 are pulled outwardly and rotated so as to be in an unlatched position. The interconnected support bed 57 and its load may be elevated to any desired height but is also easily movable with only a quarter inch clearance between the same and the supporting surface. This is extremely important in many moving type operations such as refrigerators whereupon the doorway clearance is very close as it is seen the mover apparatus 12 may be constructed of a width to go through conventional doors and the height may be easily regulated.
In an operation where considerable height is required, on upward movement of the connector and lift means 16 through the jack means 20, it is obvious that the anchor assemblies 38 on the rear tube members 32 may be moved to the latched position to hold the same in this relationship. The base member 71 and base bar 75 is thereupon raised upwardly by unlatching of the respective anchor assemblies 38 on the stub members 80. On reaching a position adjacent the rear tube members 32, the anchor assemblies 38 are latched to achieve the position as shown in FIG. 8. Then, the anchor assemblies 38 on the rear tubular members 32 can be again moved to the inactive position whereupon the jack means 20 can be actuated to provide additional height and movement of the connector and lift means 16. It is obvious that the support shafts 61 can be of any desired length for achieving great height in lifting the box 14.
The mover apparatus 12 of this invention is also easily operable through the use of the auxiliary support posts 36 to provide ease in loading and unloading from docks, pickup trucks, and the like. On reaching a desired height of the connector and lift means 16 by the jack means 20, the support posts 36 may be lowered on release of the anchor assemblies 38 on the front tube members 30 into engagement with the support surface. These tube members 30 can be anchored by the respective'anchor assemblies 38 whereupon the entire load will be carried thereon and the entire support means 18 can be raised to the uppermost abutting position as shown in FIG. 8. In this position, it is seen that a pickup truck could back under the raised support means 18 and the rear tube members 32 whereupon the support means 18 could be lowered onto the truck bed. The auxiliary support posts 36 would then be raised and the entire load pushed on the truck bed with a minimum amount of physical effort being required. This same procedure would be used in reverse to unload a heavy object from a truck bed or the like;
It is seen that the mover apparatus of this invention provides a new and novel cooperating structure attachable to more heavy objects and to elevate the same as required for movement through restricted areas where a minimum of surface clearance is required. Additionally, a pair of the mover apparatus of this invention cooperate in such a manner so as to be readily attachable to an object to be moved regardless of its particular size. The mover apparatus of this invention presents a durable structure that is economical to manufacture, simple to use, and reliable in operation providing the utmost safety during usage.
