Abstract
Abstract The trolley has a lower platform which is provided with rollers and carries two fixed lateral grills and a movable grill between the fixed grills. At least one horizontal shelf is pivotably mounted on a first of the fixed grills and is pivotable between a withdrawn position against the first fixed grill and a horizontal position in which the shelf bears against a rod of the second fixed grill. A gate mounted on one of the fixed grills to be movable inwardly of the space defined by the three grills from a closed position to an open position prevents the shelf from being pivoted to its withdrawn position so long as the gate is in its closed position. A fixed gate is disposed above the lower platform. The distance between the gates and the shelf immediately above them is less than the height of the objects to be transported by the trolley.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
225 words
A transport and display trolley comprising a lower platform, rollers mounted on the lower platform for shifting the trolley, two fixed grills and a movable grill, the three grills being vertically disposed and defining a space for receiving objects to be transported and being carried by the lower platform, at least one foldable shelf pivotably mounted on one of the fixed grills, the other fixed grill being opposed to said one fixed grill and having a transverse support means for said foldable shelf, said foldable shelf being pivotable between a folded back position in which it is folded against said one fixed grill and a horizontal position parallel to the platform, in which horizontal position said foldable shelf is supported on said support means; an openable gate movable from a closed position and an open position inwardly of said space defined by the grills and capable of interconnecting said two fixed grills in said closed position and disposed above said foldable shelf and slightly set back relative to an outer edge of said foldable shelf in said closed position whereby it precludes the pivoting of said foldable shelf to said folded back position and the unloading of said foldable shelf so long as the gate is in said closed position; and a fixed gate disposed above the lower platform connecting said two fixed grills together.
Claim 2
Dependent Claim
225 words
A transport and display trolley comprising a lower platform, rollers mounted on the lower platform for shifting the trolley, two fixed grills and a movable grill, the three grills being vertically disposed and defining a space for receiving objects to be transported and being carried by the lower platform, at least one foldable shelf pivotably mounted on one of the fixed grills, the other fixed grill being opposed to said one fixed grill and having a transverse support means for said foldable shelf, said foldable shelf being pivotable between a folded back position in which it is folded against said one fixed grill and a horizontal position parallel to the platform, in which horizontal position said foldable shelf is supported on said support means; an openable gate movable from a closed position and an open position inwardly of said space defined by the grills and capable of interconnecting said two fixed grills in said closed position and disposed above said foldable shelf and slightly set back relative to an outer edge of said foldable shelf in said closed position whereby it precludes the pivoting of said foldable shelf to said folded back position and the unloading of said foldable shelf so long as the gate is in said closed position; and a fixed gate disposed above the lower platform connecting said two fixed grills together.
Claim 3
Dependent Claim
20 words
A trolley as claimed in claim 1, wherein said support means comprises a rod carried by said other fixed grill.
Claim 4
Dependent Claim
61 words
A trolley as claimed in claim 1, wherein an elastically yieldable system pivotably mounts the openable gate on one of the fixed grills, the elastically yieldable system being capable of permitting the displacement of the openable gate inwardly of said space between said closed position and said open position in which open position it is folded against the corresponding fixed grill.
Claim 5
Dependent Claim
104 words
A trolley as claimed in claim 1, wherein the fixed grills each have substantially horizontal support means and the foldable shelf comprises two half-shelves pivoted together and provided with abutments for limiting their relative pivoting, one of said half-shelves having notches for bearing against said substantially horizontal support means of one of the fixed grills and the other half-shelf having elongated apertures slidable on said substantially horizontal support means of the other fixed grill, vertical slideways carried by said other fixed grill being cooperative with said other half-shelf for guiding and holding the half-shelf in a folded back position against said other fixed grill.
Claim 6
Dependent Claim
68 words
A trolley as claimed in claim 4, wherein the half-shelves are formed by grills having bars which are parallel to the movable grill and rods which are fixed transversely on said bars and extend beyond the bars on the open side of the trolley opposed to the movable grill and form abutment means cooperating with said bars for stopping the movement of the half-shelves in said horizontal position.
Claim 7
Dependent Claim
15 words
A trolley as claimed in claim 1, wherein recessed in the gate is an aperture.
Claim 8
Dependent Claim
86 words
A trolley as claimed in claim 1, wherein each openable gate is formed by a substantially rectangular frame bent adjacent the ends of the frame, one of the small sides of the frame being defined by two parallel pivot pins spaced apart from each other and offset relative to the general plane of the rectangular frame, a fixed support integral with one of said fixed grills pivotally supporting said pivot pins which are contained in a plane making an acute angle with the corresponding fixed grill.
Claim 9
Dependent Claim
41 words
A trolley as claimed in claim 7, wherein the small side of the openable gate remote from said pins carries an abutment for fitting on a vertical rod of the adjacent fixed grill in the closed position of the openables gate.
Claim 10
Dependent Claim
32 words
A trolley as claimed in claim 1, wherein a lower side of both said openable and fixed gates supports abutments for blocking containers or objects placed on the respective platform or shelf.
Claim 11
Dependent Claim
69 words
A trolley as claimed in claim 1, wherein the movable grill is pivotally mounted on one of the fixed grills and carries means for releasably securing said movable grill in a closed position which are vertically and rotatably movable about a vertical axis on the movable grill and define at least one hook for engaging the adjacent fixed grill and a slidable bolt member for holding said hook stationary.
Claim 12
Dependent Claim
37 words
A trolley as claimed in claim 1, wherein the distance between each of said openable and fixed gates and the shelf immediately above the respective gate is less than the height of the objects to be transported.
