US4196928A — Material pickup device

Claim 1

Independent Claim 134 words

A device for pushing material into a receptable off of a generally horizontal surface, comprising first and second elongate members having first and second major divergent portions defining intersecting axes and first and second minor divergent portions respectfully comprising angled extensions of the first and second major portions; a pusher on the lower end of the first portion; a frame on the lower end of the second portion for mounting an opened mouth receptacle with the open mouth facing the pusher; and means pivotly mounting the first and second members for relative arcuate movement about an axis in a path juxtaposing the pusher and frame including a pivot connection interconnecting the ends of the minor divergent portions; the pivot axis being offset from the intersection of the intersecting axes along the path of movement.

Claim 2

Independent Claim 134 words

A device for pushing material into a receptable off of a generally horizontal surface, comprising first and second elongate members having first and second major divergent portions defining intersecting axes and first and second minor divergent portions respectfully comprising angled extensions of the first and second major portions; a pusher on the lower end of the first portion; a frame on the lower end of the second portion for mounting an opened mouth receptacle with the open mouth facing the pusher; and means pivotly mounting the first and second members for relative arcuate movement about an axis in a path juxtaposing the pusher and frame including a pivot connection interconnecting the ends of the minor divergent portions; the pivot axis being offset from the intersection of the intersecting axes along the path of movement.

Claim 3

Dependent Claim 12 words

Claim 7

Dependent Claim 14 words

The device of claim 5 wherein the first minor portion is of arcuate configuration.

Claim 8

Dependent Claim 18 words

The device of claim 1 further comprising means engaging and biasing the first and second elongate members apart.

Claim 9

Dependent Claim 43 words

The device of claim 7 wherein the biasing means comprises a generally U-shaped spring positioned adjacent the convergence of the minor portions and having a first leg connected to one of the minor portions and a second leg engaging the other minor portion.

Claim 10

Dependent Claim 20 words

The device of claim 7 wherein the biasing means comprises a spring operative in the convergence of the minor portions.

Claim 11

Dependent Claim 81 words

The device of claim 9 further comprising a guide for constraining movement of the members between a first position juxtaposing the frame and pusher and a second position separating the frame and pusher; the guide comprising a member having a long leg connected to one of the members and a curved leg receiving the other member in the second position, and a spring gate generally parallel to the long leg selectively allowing movement of the other member out of the guide.

Claim 12

Dependent Claim 73 words

The device of claim 1 wherein the second portion comprises a tube having a lower end of generally 8-shape in cross-section, the frame comprising a strap having first and second ends and an intermediate section defining the open mouth of the receptacle and joined at opposite ends thereof to the first and second strap ends, the first and second strap ends being inserted into the opposite ends of the 8-shaped lower tube end.

Claim 13

Dependent Claim 163 words

An arrangement for supporting a sack to receive material, comprising: a peripheral frame comprising a first group of corner members providing first and second angularly related legs and a second group of generally linear members, one of the first and second groups of members being generally tubular having a passage thereinto and the other of the first and second groups of members having end portions telescopingly received in the passages; means for latching the corner and linear members in a plurality of telescoping positions including a plurality of shoulders struck from the tubular members and at least one abutment provided by the end portions, the abutments engaging the shoulders in the plurality of positions and retaining the members in a selected one of the plurality of positions; and a handle supported by the frame so that part of the peripheral frame can be positioned on a surface to enable material on the surface to be moved into the open end of the sack.

Claim 14

Dependent Claim 163 words

An arrangement for supporting a sack to receive material, comprising: a peripheral frame comprising a first group of corner members providing first and second angularly related legs and a second group of generally linear members, one of the first and second groups of members being generally tubular having a passage thereinto and the other of the first and second groups of members having end portions telescopingly received in the passages; means for latching the corner and linear members in a plurality of telescoping positions including a plurality of shoulders struck from the tubular members and at least one abutment provided by the end portions, the abutments engaging the shoulders in the plurality of positions and retaining the members in a selected one of the plurality of positions; and a handle supported by the frame so that part of the peripheral frame can be positioned on a surface to enable material on the surface to be moved into the open end of the sack.

Claim 15

Dependent Claim 47 words

The arrangement of claim 12 wherein the handle comprises a first section secured to the frame and an elongate second section for grasping by a user; and further comprising means adjustably pivotably mounting the first and second handle sections for securement in a plurality of angular positions.

Claim 16

Dependent Claim 34 words

The arrangement of claim 13 wherein the frame defines a plane and the adjustable mounting means comprises means mounting the second handle section for movement in a plane parallel to the first mentioned plane.

Claim 17

Dependent Claim 27 words

The arrangement of claim 12 wherein the frame is of generally triangular configuration having three corner members in which the legs thereof diverge at about 60 degrees.

Claim 18

Dependent Claim 11 words

The arrangement of claim 15 wherein the corner members are tubular.

Claim 19

Dependent Claim 35 words

The arrangement of claim 12 wherein the tubular members provide an opening therethrough adjacent each of the shoulders to provide access to the end portions for moving the same out of engagement with the shoulders.
