Patent Application
20140314532
The present invention is generally related to the van loading arts and, in particular, to a novel method of loading and unloading vans of either larger or smaller sizes.
Applicant's prior art patents such as Pat. No. 8,398,357 teach a fold out and lift type of crane which has been proven to be highly effective.
The present invention teaches a slideout and lift method which is also highly useful in the art.
The use of vans for transport of packages etc has become more prevalent in the art. For example, as of the Spring of 2013, New York City has ordered that the fleet of some 13,000 taxis be converted to vans.
Accordingly, it is an object of the present invention to demonstrate a crane or lift system and method of use which may be effectively used with both smaller and larger vans.
It is a further object of the invention to show a van lift and loading method which requires less floor space on the van for a more cost effective overall lift usage.
It is also an object of the invention to show a van crane or lift method which utilizes the simpler slide-out design in contrast to the more complex fold-out or rotating crane systems of the prior art. Such use reduces operating and repair costs and is thus a major advantage in the art.
The present invention may also be more easily and cost effectively manufactured than prior art systems currently in use.
These and other objects and advantages of the invention will be apparent to those of skill in the van loading and transport arts.
The following U.S. Patents show fold-out types of designs which have utility for loading trucks:
Pat. No. 8,398,357 shows a parcel delivery crane or lift which does not teach the slide-out methodology of the present invention,
Pat. No. 7,713,019 shows loading for a flat-bed truck which also uses a fold-out crane and does not teach the slide-out system of the present invention.
Building construction cranes use a pivoting and rotating design and method which is not generally related to the present slide-out design.
Tow truck types of cranes or lifts use a winch type of system and not the tube slide-out design of the present invention.
It is thus believed that the combination van and slide-out design described herein is novel and patentable over all known prior art designs currently known to those of skill in the lifting and loading arts.
A plurality of generally U-shaped support elements 21-23 are placed in a transport van of large or smaller size.
At the top center each support is a tube 30 having a slot formed in the bottom thereof.
Inside the tube 30 is another tube 40 which has a hoist 44 mounted thereon.
The inner tube 40 operates in a slide-out fashion so that it can be pushed far enough outside the van so that the hoist 44 can be used to pick up a load.
A load is then picked up and moved into the van by means of an electronic actuator.
The simpler slide-out design and method thus proves to be more effective for van usage as compared to the more complex fold-out or rotating crane designs and methods of use.
Thus, a more effective crane or lift specifically for van usage is presented.
Referring to the drawing
The van includes a first support element 21 extending around the walls 11, 14 and 12 as shown.
At the top of the support unit 21 is a first tube element 30 having a slot 31 formed in the bottom portion thereof.
Inside the first tube 30 is a second tube 40 having a hoist unit 44 mounted thereon.
The second tube and hoist combination is moved in and out of the van 10 to lift or deposit a load as will be further described.
Such is accomplished via an electric actuator to be further shown and described.
Referring to the drawing
Further support units 22 and 23 are also shown in
As further shown schematically in
Arrows 51 indicate the movement of tube 40 to inner and outer positions via an electric actuator as indicated by the letters EA.
Arrows 52 indicate movement of the hoist unit 44 to an upper or lower position to pick up or deposit a load L.
Such hoist operation is of a type utilized in the crane arts but not heretofore known in this particular van loading operation.
The method steps are generally as follows:
Such steps may vary as indicated by the method claims included herein.
The tube-within-a-tube design in combination with plural supports 21, 22 etc. and a hoist on the inner tube 40 is submitted to be patentable in its own rite as a truly novel crane or lift design. The specific combination into a van-type vehicle is believed to be even more advantageous in the loading arts.
The outer tube 30 is shown as a single tube in
While a particular lift or crane system and method of use has been shown and described, it is intended in this specification to broadly cover all equivalent systems and methods which would reasonably occur to one of skill in the art. The invention is further defined by the claims attached hereto.
