Abstract
Abstract A loading and unloading device for containers. In addition to the usual coupling means on the container there is provided an additional coupling means carried by a projecting support on the upper front part of the container. A roller and a stop are provided on one of the edges of a pit. The underside of the container is provided with a stop. A hook of a lifting arm of a lifting device on a vehicle is thus able to be coupled first with the usual coupling means and then with an additional coupling means. The device permits filling the container directly or emptying it directly, with no ramp being required.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
251 words
An apparatus for moving a container into and out of a pit, comprising, in combination: a container provided with first coupling means and with second coupling means; at least a portion of said second coupling means being disposed higher than said first coupling means; a pit in which said container may be disposed; lifting means for selective removable attachment to said first coupling means and for selective removable attachment to said portion of said second coupling means to selectively move said container into and out of said pit; a self-loading motor vehicle a rear roller provided on said vehicle; and a roller provided at one of the edges of said pit; and wherein said apparatus unloads said container from said self-loading motor vehicle into said pit, and loads said container onto said vehicle from said pit; said lifting means comprises a lifting device disposed on said vehicle; said container being displaceable on said rear roller of said vehicle by means of said lifting device; said first coupling means comprises the normal coupling means used for laying down said container on the ground; said second coupling means comprises an additional coupling means which is added to and set higher on said container than said normal coupling means for coupling to said lifting device; and when said additional coupling means is coupled to said lifting device, said container may roll on said roller provided at the edge of said pit to roll down into said pit and to roll out from said pit.
Claim 2
Independent Claim
251 words
An apparatus for moving a container into and out of a pit, comprising, in combination: a container provided with first coupling means and with second coupling means; at least a portion of said second coupling means being disposed higher than said first coupling means; a pit in which said container may be disposed; lifting means for selective removable attachment to said first coupling means and for selective removable attachment to said portion of said second coupling means to selectively move said container into and out of said pit; a self-loading motor vehicle a rear roller provided on said vehicle; and a roller provided at one of the edges of said pit; and wherein said apparatus unloads said container from said self-loading motor vehicle into said pit, and loads said container onto said vehicle from said pit; said lifting means comprises a lifting device disposed on said vehicle; said container being displaceable on said rear roller of said vehicle by means of said lifting device; said first coupling means comprises the normal coupling means used for laying down said container on the ground; said second coupling means comprises an additional coupling means which is added to and set higher on said container than said normal coupling means for coupling to said lifting device; and when said additional coupling means is coupled to said lifting device, said container may roll on said roller provided at the edge of said pit to roll down into said pit and to roll out from said pit.
Claim 3
Dependent Claim
35 words
An apparatus according to claim 1, including: a support projecting from the front wall of said container; and said additional coupling means is located on said support projecting from the front wall of said container.
Claim 4
Dependent Claim
48 words
An apparatus according to claim 1, including: a supporting arm pivotally mounted on the front wall of said container so that said supporting arm may pivot from the front wall of said container in a forward direction; and said additional coupling means is mounted on said supporting arm.
Claim 5
Dependent Claim
43 words
An apparatus according to claim 1, including: stops provided on the front part of the underside of said container and on said edge of said pit which is provided with said roller, respectively, to support said container when selectively changing the coupling arrangement.
Claim 6
Independent Claim
281 words
An apparatus for moving a container into and out of a pit, comprising, in combination: a container provided with first coupling means and with second coupling means; at least a portion of said second coupling means being disposed higher than said first coupling means; a pit in which said container may be disposed; lifting means for selective removable attachment to said first coupling means and for selective removable attachment to said portion of said second coupling means to selectively move said container into and out of said pit; a self-loading motor vehicle; a rear roller provided on said vehicle; and a roller provided at one of the edges of said pit; and wherein said apparatus unloads said container from said self-loading motor vehicle into said pit, and loads said container onto said vehicle from said pit; said lifting means comprises a lifting device disposed on said vehicle; said container being displaceable on said rear roller of said vehicle by means of said lifting device; said first coupling means comprises the normal coupling means used for laying down said container on the ground; said second coupling means comprises an additional coupling means which is added to and set higher on said container than said normal coupling means for coupling to said lifting device; when said additional coupling means is coupled to said lifting device, said container may roll on said roller provided at the edge of said pit to roll down into said pit and to roll out from said pit; and an additional frame for receiving said container, wherein said additional frame may be lowered into said pit and lifted out from said pit up to the edge of said pit.
Claim 7
Independent Claim
281 words
An apparatus for moving a container into and out of a pit, comprising, in combination: a container provided with first coupling means and with second coupling means; at least a portion of said second coupling means being disposed higher than said first coupling means; a pit in which said container may be disposed; lifting means for selective removable attachment to said first coupling means and for selective removable attachment to said portion of said second coupling means to selectively move said container into and out of said pit; a self-loading motor vehicle; a rear roller provided on said vehicle; and a roller provided at one of the edges of said pit; and wherein said apparatus unloads said container from said self-loading motor vehicle into said pit, and loads said container onto said vehicle from said pit; said lifting means comprises a lifting device disposed on said vehicle; said container being displaceable on said rear roller of said vehicle by means of said lifting device; said first coupling means comprises the normal coupling means used for laying down said container on the ground; said second coupling means comprises an additional coupling means which is added to and set higher on said container than said normal coupling means for coupling to said lifting device; when said additional coupling means is coupled to said lifting device, said container may roll on said roller provided at the edge of said pit to roll down into said pit and to roll out from said pit; and an additional frame for receiving said container, wherein said additional frame may be lowered into said pit and lifted out from said pit up to the edge of said pit.
Claim 8
Dependent Claim
24 words
An apparatus according to claim 5, wherein: said additional frame carries said additional coupling means for coupling to said lifting device of said vehicle.
Claim 9
Dependent Claim
23 words
An apparatus according to claim 5, wherein said additional frame may be lifted in said pit by means of a separate lifting device.
Claim 10
Dependent Claim
20 words
An apparatus according to claim 5, including: rollers and rest projections provided on the front edge of said additional frame.
Claim 11
Dependent Claim
47 words
An apparatus according to claim 1, including: roller means provided on a portion of said container which is remote from said edge of said pit; whereby said container may roll on said roller means to roll down into said pit and to roll out from said pit.
