Flexible reticular structure

Abstract

The present invention relates to a flexible reticular structure which comprises a movable surface the movement of which is operated by operating means, and is characterized in that said surface is formed by a plurality of modules linked to one another. Said modules forming the surface are preferably linked to one another by means of attachment rods, each of said rods being housed in holes provided in at least two of said modules. The present invention prevents the need to disassemble and replace the entire movable surface, rather only the affected module or modules, for repair or maintenance.

(2) FIG. 1 is a perspective view of the upper part of a portion of a flexible reticular structure according to the present invention;

(3) FIG. 2 is a perspective view of the lower part of a portion of a flexible reticular structure according to the present invention;

(4) FIG. 3 is a perspective view of the upper part of a larger module;

(5) FIG. 4 is a perspective view of the upper part of a smaller module;

(6) FIG. 5 is a perspective view of the lower part of a smaller module arranged inside the cavity of a larger module;

(7) FIG. 6 is a perspective view of the upper part of a portion of a flexible reticular structure according to the present invention, with a plurality of brushes assembled on the movable surface; and

(8) FIG. 7 is a perspective view of one side of the flexible reticular structure according to the present invention, where how the movement of said belt is operated can be seen. The operating or drive pinion is depicted as a 6 tooth pinion, but it is obvious for a person skilled in the art that pinions with a larger number of teeth or several pinions can be used to facilitate and better distribute the drive force.

(9) FIG. 8 is a perspective view of one side of the flexible reticular structure according to the present invention, where how it can be operated with several drive pinions as a result of its design can be seen.

(10) FIG. 9 is a bottom perspective view showing an additional element, a bristle brush in this preferred embodiment, showing the anchoring clips for assembling them in the fixing holes of the flexible reticular structure.

(11) FIG. 10 depicts a module, such as that depicted in FIG. 3, with a perforated upper surface forming a reticulate for transmitting a vacuum or any fluid between the lower cavity and the outside.

DETAILED DESCRIPTION

(12) FIG. 1 depicts the perspective view of the movable surface, indicated in general by means of reference number 1, of the flexible reticular structure according to the present invention.

(13) Said movable surface 1 is preferably operated by means of a single motor 2, which can be seen in FIG. 7, in both directions.

(14) Furthermore, said surface 1 is modular, i.e., it is formed by a plurality of modules 3, 4. According to the embodiment depicted in the drawings, said modules are of two types, i.e., larger modules 3 and smaller modules 4, which are depicted separately in FIGS. 3 and 4, respectively.

(15) Said larger modules 3 and smaller modules 4 are arranged both longitudinally and transversely in an alternating manner, as can be seen in FIGS. 1 and 2, such that each larger module 3 will be surrounded by four smaller modules 4, and vice versa.

(16) As indicated by their name, the larger modules 3 have larger dimensions than the smaller modules 4, and according to the embodiment depicted in the drawings, said larger modules 3 have a rectangular base, whereas said smaller modules 4 have a quadrangular base. According to this embodiment, the width of said larger modules 3 is substantially equal to the length of said smaller modules 4, as can be seen in FIGS. 1 and 2.

(17) Although not depicted in the drawings, termination parts with a particular measurement can be arranged on the sides so that the sides are straight.

(18) According to the depicted embodiment, said modules 3 and 4 are attached in rows, three in the case of the embodiment of FIGS. 1 and 2. The attachment or coupling of said modules is done by means of longitudinal rods 5 which are introduced in holes 6 of said modules 3, 4.

(19) As can be better seen in FIGS. 3 and 4, said holes 6 are arranged in flanges 7 of the modules 3, 4, projecting laterally from said modules 3, 4.

(20) Furthermore, for covering the space defined by said rods 5 when attaching the modules 3, 4, said larger modules 3 comprise side projections 9, as shown in FIG. 3, such that the surface 1 will be substantially smooth.

(21) To facilitate transporting the flexible reticular structure according to the present invention in disassembled position, the larger modules 3 comprise in their lower part a cavity 8 for the housing of a smaller module 4, as can be seen in FIG. 5, such that the smaller modules 4 will not take up additional space during transport.

(22) Additional elements can be arranged on said movable surface 1. To that end, said modules 3, 4 comprise fixing holes 10, although they may comprise any suitable fixing or coupling means (depicted as round holes, these can be any anchoring method: round holes, square holes, clips, guides, etc.).

(23) In this depiction, the brushes include clips 13 on the lower surface fitting with the fixing holes 10.

(24) According to the embodiment depicted in FIG. 6, said additional elements are brushes 11 that are coupled on said modules 3, 4. In this case, to allow the bristles of the brushes 11 to open when pressing on their lower surface, each module 3, 4 comprises a projection 12 which in the assembled position will press on the lower surface of said brushes 11 so that their bristles open (desired effect in sheet material cutting applications)

(25) These brushes 11 are preferably used serving as a base for a sheet material, such as a piece of paper or fabric, which will be cut by means of a suitable cutting device. The bristles of said brushes 11 will serve as a support for the sheet material, but the blade of the cutting device will be able to pass between them.

(26) As can be seen in this FIG. 6, the sides of the larger modules 3 stick out further with respect to the width of the brushes 11.

(27) Although reference has been made to a specific embodiment of the invention, it is obvious for a person skilled in the art that the flexible reticular structure that has been described is susceptible to a number of variations and modifications, and that all the mentioned details can be replaced with other technically equivalent details, without departing from the scope of protection defined by the attached claims.
