Rolling device for display panels

Abstract

 These panels are arranged in vertical planes coupled via their lower edges in some upper guides and other lower ones belonging to the structure of a display cabinet.
It is characterised in that each panel incorporates at least one pair of support wheels on the flooring close to each other and arranged in the most forward part of the lower section which projects in front of the respective lower guide, with one of the wheels being adjustable in height.
The design thus manages to avoid knocks and vibrations in the panels during their displacement as a consequence of the separation joints between the flagstones of the flooring.

Description

OBJECT OF THE INVENTION

[0001] As stated in the title of this specification, the present invention relates to a rolling device for display panels which, being associated with the structure of the panel, allows it to slide on floorings with separation joints between flagstones without those joints transmitting or creating noises and knocks, nor any vibrations, to the weight of the wheels for displacement of the panels.

STATE OF THE ART

[0002] Display cabinets which have mobile panels that roll on the floor of the shop or exhibition hall currently present a disturbing problem aggravated by the considerable weight of those panels when what is being displayed is ceramic tiles.

[0003] In fact, the wheels which move along the floor produce a disturbing noise accompanied by small knocks, as they pass over the joints of the flooring.

[0004] Some of these joints are of very considerable dimensions, such as those created in rustic floorings, which aggravates the problem even more.

DESCRIPTION OF THE INVENTION

[0005] With the aim of achieving the objectives and avoiding the drawbacks mentioned above, the invention proposes a rolling device for display panels characterised in that it incorporates a small auxiliary wheel, adjustable in height, which will be located in front or behind of at least one of the main displacement wheels of the panel, which main wheel sits on the floor, and with both wheels being arranged in the most forward part of the lower part of the panel.

[0006] The display panels are of the type which are coupled to some lower guides forming part of the structure of a display cabinet, and containing also an upper guide.

[0007] These panels slide in and out in vertical planes, supported on lower guides and also on the inventive wheel device via the main and the auxiliary wheel, both of them arranged close to each other.

[0008] They will preferably be located in front of all the wheels which move along the floor. Their support point will be level with that of the main wheel and the distance between the rotation axes of both wheels, or, more accurately, their contact points with the floor, will always be greater than the maximum width of the flooring joint separating adjacent flagstones, thereby maintaining a continuity in the rolling without interruptions or knocks.

[0009] Below, in order to facilitate a better understanding of this specification and forming an integral part thereof, some figures are attached in which, on an illustrative rather than limiting basis, the most characteristic details of the invention have been represented.

DESCRIPTION OF THE PREFPRRED FORM OF EMBODIMENT

[0011] Considering the numbering adopted in the figures, the rolling device is applicable to display panels 1 arranged in vertical planes which are conducted via their lower sections 2 of the respective panel frame 1 in some parallel guides 3 belonging to a display panel 4, and at the same time said lower sections 2 of the panel frame 1 in principal incorporate a first main wheel 5 in some forward zones which rests on the flooring 6 in order to facilitate the displacement of the respective panel 1 backwards and forwards, introducing it and extracting it to and from the outside in order to show the products housed in the panel 1. Said panels 1 are also guided in the upper part of the cabinet 4.

[0012] This main wheel 5 is coupled in a transverse shaft 7 fitting via its ends in some short facing and inclined slots 8 with at least two end recesses, a forward one 9 and a rear one 10, in order to be able to locate that main wheel 5 further forwards or further backwards and also with a greater or lesser height, all this within limited margins.

[0013] The securing of the main wheel 5 is done with screws 11 threaded into the ends of the transverse axis 7 whose wide head will press against the lower section of the panel frame 1 which essentially presents a profile in the form of an inverted "U", the main wheel 5 then being housed inside that profile 2.

[0014] Also included is a second auxiliary wheel 12 coupled in a small support 13 adjustable in height and arranged in front of the main wheel 5, the auxiliary wheel 12 thereby being able to be located at the height that is required with respect to the main wheel 5.

[0015] In this way, the support on the flooring 6 of the panel 1 in its most forward part will be on the wheel 5 and 12, which will avoid knocks and vibrations of the panels 1 during their displacement when they roll over the separation joints 14 in the flagstones of the flooring 6.

[0016] In order to adjust the height of the auxiliary wheel 12, the small support 13 includes a pair of threaded holes 15 in which are fitted respective screws 16, whose conical heads are arranged to correspond with a slot, also of conical structure 17, belonging to a frontal piece 18 that is integral with a free end of the lower section 2 of the panel frame 1.

[0017] In this way, once the required height of the auxiliary wheel 12 with respect to the main one 5 has been determined, the screws 16 are then tightened, and their heads press against the inclined faces of their slot 17, said auxiliary wheel 12 thus being immobilised together with the support 13 against the frame of the respective panel 1.

[0018] The support point will be levelled with that of the main wheel 5 and Lhe distance between the axes of rotation of both wheels, or more accurately their contact points with the floor, will at all times be greater than the maximum width of the separation joint 14 between flagstones of the flooring 6.

[0019] we can clearly see the effect that is produced in the application represented in figure 4, when the auxiliary wheel 12 arrives at a joint 14, it passes over it without knocking, since the main wheel 5 supports the panel, in such a way that when one of the wheels coincides with the joint the other paired wheel will always be supported on the flat surface of the flooring.

[0020] When said main wheel 5 passes over the joint 14, the auxiliary wheel 12 is already in contact with the flooring, thereby avoiding vibrations and knocks to the panels.

[0021] The threaded holes 15 of the support 13 are essentially located in some hexagonal-shaped false pieces 19 integral with said vertical support 13.
