Definitions

  • the present invention relates to an automatic covering element particularly for pits of mechanical workshops and the like.
  • the covering element is stored in practice by substantially rolling it up in a spiral configuration, with the need to provide appropriate spiral guides which face each other at the end of the pit.
  • Document DE 34155516 A1 discloses an assembly pit, the opening of which is covered by a series of panels arranged one behind the other and connected to one another by cables. In the open position, these panels, equipped with rollers, are suspended in a storage region on horizontal suspension rails. By means of cable
  • pulls the panels can alternately be pulled from the open to the covering position and vice versa.
  • Document US 4,603,723 discloses a shutter which has a number of wide slats connected to each other by a hinge mechanism with the slats remaining separate so that an opening for a side gate can be formed at a desired position on the shutter.
  • the slats are provided at both ends with groups of large diameter rollers and of small diameter rollers which are connected to each other between adjacent slats and are arranged alternatively, larger and smaller.
  • both groups of rollers run the same route.
  • the notch provided at the inlet of the horizontal guide allows only the small diameter rollers to come inside. The large diameter rollers go past the notch, without dropping past guide and the small diameter rollers go down the notch toward the guide. Thus the slats are folded and housed one after the other.
  • Document FR2 674 565 discloses a device for closing/opening pits, comprising a series of shut-off elements which, when the pit is closed, are positioned transversely with respect to the longitudinal axis of the pit, and edge-to-edge over at least a part of the top opening of this pit.
  • This device in particular comprises guide means in which the shut-off elements slide and which extend longitudinally over the length of that part of the pit which is to be shut off.
  • the shut-off elements are connected together by linking means which allow them to be folded accordion-style, each shut-off element including, on its inside face, rack means which can engage with gear means meshing with the rack means, operated via actuating means.
  • Document DE 35 44 944 A1 discloses a roller shutter comprising hollow bars connected to one another in an articulated manner and guided in side grooves and over a drivable lifting shaft.
  • the lifting shaft is mounted at both ends in a carrier having a guide groove.
  • the guide is divided up by a deflection wedge into two separate branches reaching a support at the lower carrier end.
  • Guide bolts arranged only at the relevant end of every second bar interact with the guide which is present only on one side, the end pins, offset alternately, of said guide bolts folding
  • guide ribs on the front and rear sides, are provided on the carriers, these ribs extending over the entire height of the storage space and serving at the same time as catch-locking tongues for the removable support channel.
  • Document CH 606 751 discloses a roller shutter, wherein the panels forming the shutter are forced by a point of belt reversal to be positioned in a storage space.
  • the panels are provided with elements protruding from the sliding plane of the shutter, which are used by the point of belt reversal to direct the panels in one of the guiding paths in an alternating way, in order to obtain a flap packing of the shutter.
  • the aim of the disclosure is to solve the problem described above by providing an automatic covering element particularly for pits of mechanical workshops and the like which can be adapted easily to any customer demand without having constructive complications if the length of the pit is changed.
  • an object of the disclosure is to provide an automatic covering element which can be stored without having to resort to spiral winding, consequently simplifying all the operations for provision and facilitating the sliding of the covering element.
  • Another object of the present disclosure is to provide an automatic covering element which, thanks to its particular constructive characteristics, is capable of giving the greatest assurances of reliability and safety in use.
  • Still another object of the present disclosure is to provide an automatic covering element particularly for pits of mechanical workshops and the like which can be obtained easily starting from commonly commercially available elements and materials and is also competitive from an economical standpoint.
  • an automatic covering element particularly for pits of mechanical workshops and the like which comprises a shutter-like covering which is guided so that it can slide within guides arranged on the longitudinal edges of a pit and the like and can be positioned in a storage region, motor means being further provided for moving said shutter-like covering, characterized in that it comprises means for the concertina positioning of said shutter-like covering in said storage region.
  • the present invention provides an automatic covering element in accordance with independent claim 1. Preferred embodiments of the invention are reflected in the dependent claims.
  • the covering element generally designated by the reference numeral 1, can be used to cover automatically pits 2 which are used typically in mechanical workshops and the like.
  • the covering element comprises a shutter-like covering, generally designated by the reference numeral 3, which is constituted by a plurality of transverse bars or slats 4, to the ends of which chain-link elements, designated by the reference numeral 5, are connected by respective pivots to form a chain and have, at each pivot 8 of the chain 9, rollers 6 which are guided slidingly within longitudinal guides 7 which lie at the longitudinal edges of the pit 2.
  • the covering element can slide within the guides 7, which have, at one end of the pit 2 where a storage region 10 is provided, a vertical guiding portion 11 which is open in a downward region and arranges the shutter-like covering along a substantially vertical plane.
  • a peculiar characteristic resides in that means are provided for the concertina arrangement, i.e. for the side-by-side positioning of flaps of the shutter-like covering in the storage region 10.
  • Such means are provided by a storage guide 20, which is arranged with a subhorizontal orientation so as to be at a lower level at the end that lies opposite the end located proximate to the open end of the vertical guide portion 11.
  • brackets 22 which support a storage roller 23 which is spaced with respect to the sliding plane of the chain formed by the links 5.
  • the storage roller 23 is designed to engage an inlet end 25, which is folded upwardly, of the storage guides 20, which acts as a guiding inlet, so that when the link 5 provided with the bracket 22 arrives at the guiding inlet portion 25 of the guide 20, the roller in practice is picked up, so that it follows the guide 20, and the chain formed by the links 5 is suspended, obtaining a concertina or flap packing of the shutter-like covering.
  • motor means which are constituted by a motor 30 which drives a pair of pinions 31 which mesh between the rollers 6 of the chain 9, consequently moving the bars which provide the shutter-like covering.
  • positioning rollers 40 which have an adjustable position, act on a central portion of the length of the bars 4 and are supported by the frame 41, which is connected to the fixed structure and supports internally the motor means 30 and externally the storage guides 20.
  • the rollers 40 are designed to keep the bars guided, preventing their incorrect positioning during their concertina or suspended flap arrangement.
  • an automatic covering element is provided which, thanks to the presence of the storage rollers 23, allows in practice to disengage the bars which constitute the shutter-like covering element from the guides, allowing the chain to arrange itself in a concertina fashion, thus achieving easy and automatic packing, without forcing and without having to push to pack the flaps, since packing occurs automatically due to the inclination of the storage guides 20 which facilitate packing.
  • Another important aspect further resides in that as the length of the covering varies, it is not necessary to carry out particular modifications, since the length of the shutter-like covering which can be stored can be changed simply by modifying the height of the storage region and the distance between the brackets 22 and the roller 23.
