Abstract
Abstract This invention relates to a handling assembly incorporating deformable suction cups for handling objects presenting a smooth and non-porous surface for application of the suction cups, the assembly comprising a body and at least one deformable suction cup mounted on this body and a release mechanism mounted mobile on the body; a single-piece construction control assembly molded in plastic and formed by rods in the shape of a rhombus with a pair of control zones, each connected to a suction cup, located at one set of opposite apices and a pair of control locations, each connected to a control member, located at the other set of opposite apices so that as the control member is moved by the operator, the rhombus is deformed and the suction cups are correspondingly deformed and released from the object being handled.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
201 words
A handling assembly for handling objects, such as plate glass, presenting a smooth and non-porous surface, wherein said handling assembly comprises: a body; at least two coplanar deformable suction cups mounted on said body; and a release mechanism for suppressing the gripping effect of said suction cups by deformation of the edge of each suction cup, said release mechanism having (a) at least one control member mounted on and mobile to said body, (b) a single-piece construction control assembly molded in a plastic material and formed by rods in the shape of a polygon with at least two control zones and at least one control location positioned on said polygon, said control assembly being mounted on and mobile to said body, and each said suction cup being connected to at least one said control zone, and (c) at least one control connection, said control connection connected to said control location and connecting said control member to said control assembly such that when said control member is moved with respect to said body by the operator, said polygon shape of said control assembly is deformed with respect to said body and said suction cups are correspondingly deformed with respect to said object.
Claim 2
Dependent Claim
201 words
A handling assembly for handling objects, such as plate glass, presenting a smooth and non-porous surface, wherein said handling assembly comprises: a body; at least two coplanar deformable suction cups mounted on said body; and a release mechanism for suppressing the gripping effect of said suction cups by deformation of the edge of each suction cup, said release mechanism having (a) at least one control member mounted on and mobile to said body, (b) a single-piece construction control assembly molded in a plastic material and formed by rods in the shape of a polygon with at least two control zones and at least one control location positioned on said polygon, said control assembly being mounted on and mobile to said body, and each said suction cup being connected to at least one said control zone, and (c) at least one control connection, said control connection connected to said control location and connecting said control member to said control assembly such that when said control member is moved with respect to said body by the operator, said polygon shape of said control assembly is deformed with respect to said body and said suction cups are correspondingly deformed with respect to said object.
Claim 3
Dependent Claim
41 words
The handling assembly of claim 1, wherein said handling assembly comprises two suction cups, and said polygon is shaped substantially as a rhombus in its non-deformed shape and said control zones are disposed substantially at two opposite apices of said rhombus.
Claim 4
Dependent Claim
30 words
The handling assembly of claim 2, wherein the control connections and control locations are two in number and are disposed substantially at the other two opposite apices of said rhombus.
Claim 5
Dependent Claim
57 words
The handling assembly of claim 1, wherein each said rod is connected to a suction cup by a suction cup finger connected to and projecting from said suction cup and positioned within said control zone of said control assembly, said control zone consisting of a groove which firmly connects said suction cup finger to said control assembly.
Claim 6
Dependent Claim
35 words
The handling assembly of claim 4, wherein each suction cup is made by molding, and each suction cup finger is a separate piece and is connected with the edge of the suction cup associated therewith.
Claim 7
Dependent Claim
46 words
The handling assembly of claim 4, wherein each said suction cup is made by molding, and each suction cup finger is connected to the edge of the suction cup associated therewith and each suction cup and corresponding suction cup finger is molded in a single-body piece.
Claim 8
Dependent Claim
60 words
The handling assembly of claim 1, wherein each control connection consists of at least one control finger with two ends, connected at one end to a said control member and positioned at the other end within said control location of said control assembly, said control location consisting of a groove which firmly connects said control finger to said control assembly.
Claim 9
Dependent Claim
37 words
The handling assembly of claim 7, wherein each control member is made of a molded plastic material and each control finger is made in one piece with the control member associated therewith at the moment of molding.
Claim 10
Dependent Claim
22 words
The handling assembly of claim 7, wherein said control finger is fixed on a guide block mounted to slide on said body.
Claim 11
Dependent Claim
63 words
The handling assembly of claim 1, wherein said body further consists of rear and front sides, an upper face and a handle firmly connected to the said upper face of said body, said handle being inclined from said front side of said handle to said rear side of said handle with respect to the plane formed by the faces of said suction cups.
