Definitions

  • This invention relates to bellows-like collapsible canvas coverings which are widely used to keep selective strictlyly sheltered or uncovered certain areas, like for instance tennis courts, commercial storage areas and so on, depending upon the variations of the weather condit­ions.
  • Said collapsible canvas coverings substantially comprise a waterproof canvas supported by a plurality of mutually parallel arches connected to each other by means of pantograph linkages and capable of being brought closer or apart, being driven by a preferably electric motor. When the arches are moved apart from each other they drag the canvas therewith, whereby said canvas is extended to cover the sheltered area; to uncover the same area, it is just enough to take the arches back closer to each other, and the canvas folds in a bellows-­like fashion.
  • the pantograph linkages presently used to connect the arches to each other comprise, in the simplest embodiment thereof, two rods centrally pivoted to each other like a St.Andrews' cross, each rod having the lower end thereof pivotally connected to the base of an arch, and the upper end thereof terminating with a sleeve which is slidably mounted on a vertical rod fasten­ed at both ends thereof to the adjacent arch.
  • pantograph linkage rods When the arches are moved apart, the pantograph linkage rods open in a scissor-like fashion and the ends thereof slide down­wards along the vertical rods, while the lower ends move apart from the arches they are pivoted to, causing the hinges to open up.
  • pantograph linkage In fact, if an operator leaves absent-mindedly his hand lying on a pantograph linkage, during uncovering of the sheltered area, he is subjected to the risk of having his hand cut off by the pantograph linkage components while they are closing in a scissor-like fashion and they are mutually approaching up to a point wherein they are actually contacting each other.
  • pantograph linkage comprises two mutually pivoted rods, the pivot being at the mid-point of the rods, in a known St.Andrews' cross fashion, said rod being bent at the pivoting area, whereby the arm, upstream from said bend lies in a position offset relative to the other arm and relative to the pivot pin.
  • the canvas is never damaged, and the room available between the linkage members allows the folded canvas to find enough room when normally pushed between said members either by gravity or by the wind. Said room is also sufficient in order to avoid injuring or cutting the operator fingers, if he had inadvertently laid his hand between the pantograph linkage members when the arches are brought together.
  • FIG. 1 there is shown a canvas covering according to this invention mounted above a tennis court and kept in an open position.
  • Said canvas covering comprises substantially a canvas 1 of water­proof material, supported by a plurality of metal arches 2 whose bases are mounted on wheels which are able to roll on guides 3 lying on the ground.
  • a door 4 is provided for entrance underneath the canvas covering when it is in a closed position.
  • a motor drives arches 2 to move closer or apart from each other, with a corresponding partial or total collapsing or closure of the collapsible canvas covering.
  • arches 2 In the position shown in the Figure, arches 2 have been brought together, in two groups, each group corresponding to a half of the canvas covering, whereby the collapsible covering is in a collapsed position.
  • FIG 2 which shows, in an enlarged view, taken from inside the court, the part of collapsible canvas cover­ing included in the rectangle shown in hatched line in Figure 1, as it is shown, every arch 2 is provided at the lower end thereof with a wheel 5 and, at a certain height above the ground, also with a vertical bar 6 carrying a sleeve mounted thereon and able to slide on said rod.
  • Each arch 2 is connected to the adjacent one by me of a pantograph linkage unit comprising rods 7, 7′ centrally and rotatably pivoted to each other, at pivot pin 8.
  • Rod 7 has the lower end thereof pivoted to an arch 2 at a hinge 10, while the opposite end thereof is fastened to sleeve 18 slidingly mounted within vertical bar 6 associated with adjacent arch 2′.
  • Rod 7′ in turn has the lower end thereof pivoted to said ad­jacent arch at pivot point 9, while the upper end there­of is fastened to sleeve 17 slidably mounted on vertical bar 6 of arch 2 whereto rod 7 is pivoted at point 10. Between pairs of arches where is shown folds 11 of canvas 1, folded in a bellows-like fashion.
  • rod 7 is divided into two sections: an arm 15 located above or upstream said central area 13, and arm 16 located below or downstream from said central region 13.
  • rod 7′ as well is divided into two sections: an arm 15′ located above central area 13′ and an arm 16′ located below said central area.
  • Arms 15 and 16 of rod 7 are both mutually offset and offset relative to opening 14, as well as arms 15′ and 16′ which are both mutually offset and off­ set relative to opening 14.
  • Lower arm 16 of rod 7 is connected at the lower end thereof, to arch 2 by means of hinge 10.
  • Upper arm 15 of the same rod 7 is fastened at the upper end thereof to sleeve 18 which is slidably mounted on vertical bar 6 fastened to arch 2′, the latter arch being immediately adjacent to the arch on which the lower end of said bar is fastened.
  • Lower arm 16′ of rod 7′ is pivoted to arch 2′ at 9, and upper arm 15′ of said rod 7′ is fastened to sleeve 17 which is slidably mounted within bar 6 fasten­ed on upper part of arch 2 immediately close to arch 2′ whereupon there is pivoted, at 9, the lower arm 16′ of said rod.
  • FIG 4 there is shown another embodiment of the pantograph linkage element according to this invention.
  • rods 7 and 7′ are not bent at their central area 13, but they are actually interrupted at said area.
  • This embodiment was obtained using a rectangular cross section metal rod whose two equal length segments 15 and 16 are welded, respectively at the lower end and at the upper end thereof, on the side of a segment 13, substantially shorter than the first two, but of the same material.
  • Rod 7′ has been constructed in the same way, and both the short central segments 13 and 13′ are provided with an opening 14 adapted to receive pivot pin 8.
  • this embodiment as well there is present the basic feature of this invent­ion, i.e. the fact that the two arms of each rod are offset both mutually and relative to opening 14.
  • Figure 5 which shows a side elevational view of the lower part of an arch 2
  • arms 15, 16 and 15′, 16′ of the rods are not straight, but are rather slightly curved, in order to follow the curvature of arch 2.
  • This feature is particularly useful in that it enables the members of the pantograph linkage to be kept very close to the arches, whereby room is gained underneath the collapsible canvas covering, and in addition the whole structure acquires a better appearance.
  • the room gained is particularly important in those cases when the pantograph linkage members reach a height from 4 to 5 meters, and that is true in those cases where the dimensions of the collapsible canvas covering are such as to allow a pitch higher than 3 meters to be used between adjacent arches.
