Definitions

  • ABSTRACT This extensible support element for carrying and tensioning blinds, shades or screens, and also for opening and closing same, is also applicable to tents, swimming-pool covers, greenhouse shades and miscellaneous shelters, and comprises toggle elements wherein the pivot means interconnecting the two links of the toggle is shifted by a same value and in the same direction in relation to the middle point of the links according as it is desired to impart a curved or straight configuration to said support element.
  • Support elements of this general type are intended as a rule for carrying and tensioning blinds, shades or screens, and also for opening and closing same.
  • the present invention is applicable to articles differring considerably from conventional blinds and screens, as will appear during the following description.
  • blinds, shades and screens are divided into various groups according to their inherent structure and also their aesthetic appearance.
  • blinds of this common type are relatively unaesthetic and scarcely original in design.
  • the canvas cannot be tensioned without taking special cares or using additional devices, so that it acts as a sail in case of strong wind.
  • Another type of blind is the so-called invisible-arm blind wherein the arms are pivoted substantially intermediate their ends and concealed under the canvas; thus, during the blind opening movement these arms extend parallel to the plane of the canvas which, as in the preceding type, is wound on a roller.
  • the inconveniences of this type of blind are substantially the same as those observed with awning-blinds.
  • Another, more original and aesthetic type of blind is the socalled basket or hood type wherein the canvas is carried by bows perpendicular to the unfolding direction and pivoted at their ends to the house wall or like surface.
  • blinds of this type have a satisfactory appearance and are generally much appreciated by users, moreover, their sail effect is moderate. However, their cost is relatively high due to a more complicate manufacture. Finally, when closing the blind accordion-like folds are formed between the bows which tend to retain rainwater and accumulate dust, thus producing unsightly marks in the bottom of the folds.
  • a extensible support element for a protection or blind canvas which can be used with all types of blinds, canopies and more generally all covers, hoods and shelters in which the weather protection is obtained by using a folding canvas, such as camping or other tents, swimming-pool covers, greenhouse shades, sports-grounds cover or roofing, playground covers and the like
  • said extensible support element being of the type comprising a series of pivotally interconnected toggle links, said element being characterized in that the common pivot pin or like means interconnecting the two links of at least one toggle is shifted by a same value and in the same direction in relation to the middle point of said two links.
  • this support element deviates at the level of each toggle having an eccentric pivotal connection, whereby a development of any desired configuration, and notably the rounded or arched contour of a so-called “basket” or hood” blind, can be imparted to each support element and to the canvas carried thereby.
  • each pair of links of said toggles are provided with several pivot points permetting the desired variations in the configuration of the extended support element.
  • a specific application of the present invention re sides in a blind of the so-called round hood" type comprising at least two parallel support elements interconnected at the level of the pivotal connection between one toggle and the next one by horizontal rods supporting the canvas, the latter being secured along its front or outermost edge to the foremost rod and adapted to be wound at its rear or innermost edge on a roller carried by the wall or like supporting surface, to which on the other hand the rear end of each support element is pivotally attached.
  • this blind combines the advantageous features of awning-blinds with those of the basket or hood blinds without having their inconveniences.
  • lateral panels are associated with the blind, they are secured along their upper edges, to the upper pivot means interconnecting successive toggles, said upper edges further receiving therethrough, in the area extending between said pivot means a cord kept under permanent tension so as to impart a better appearance to said lateral panels when the blind is not fully extended.
  • this support element is incorporated in the frame structure of a habitable tent.
  • This frame structure comprises an extensible support element consisting of at least three, and preferably four, five or six toggles, wherein all the pivot means interconnecting their links are shifted by a same value and in the same direction in relation to the middle point of said links, whereby the development of the support element takes place along a circular arc and impart thereto, after the ends of the support element have been joined together at a common point, a spider configuration wherein the number of arms corresponds to the number of toggles constitutings same, saiad support element being disposed horizontally and receiving on the one hand a set of rods each secured at one end of the tip of one of the spider arms, said rods being interconnected at the other ends so as to constitute a frame structure converging upwards and adapted to be covered with a cap-forming canvas or cloth and on the other hand a base comprising at least three legs for supporting the assembly, the support element being furthermore adapted to receive
  • a tent frame comprises a plurality of extensible support elements carried by the upper end ofa vertical pole and adapted to be extended radially in relation to said pole so as to describe circular arcs disposed in vertical planes until their free end bear on the ground, so that they constitute together a frame structure of substantially semispherica vault or dome configuration adapted to receive a suitably shaped canvas.
  • this support element may be incorporated in a roof or cover structure of swimming pool, greenhouse or other similar areas to be covered or protected against weather conditions.
  • the vertical pivot pins of at least some of the toggles of the support elements are shifted by a same value and in the same direction in order to cause said element to extend along a curved path, at least two support elements being arranged parallel to each other and interconnected by horizontal parallel rods carried by the upper pivot means from one toggle to another, said rods supporting the cover or canvas, preferably of translucent material, of which the front edge is secured to the foremost rod and the opposite or rear edge is wound on a roller disposed on or close to the ground.
  • Another interesting application of this invention consists of a stand for street-and-market packman or itinerant merchant.
  • At least two parallel support elements comprise each a variable number of intermediate or central toggles adapted to extend circularly and arranged between a variable number of lateral toggles adapted to expand along a straight line, the number of these lateral toggles being the same on either side of the central toggles, whereby each element thus constituted is adapted to expand and form an arch, the aforesaid elements being interconnected by parallel horizontal rods carried by the pivot means disposed between adjacent toggles, the rods interconnecting the external pivot means of the toggles constituting the portion of circular arc configuration of the elements intended for supporting the protection canvas; moreover, at the proper level there are provided, on at least one of the rectilinear portions of each support elements, a pair of rods interconnecting the two pivot means located at said level and pertaining to two adjacent toggles, said last-named pair of rods being adapted to carry a display of goods or the like.

  • the first toggle of each element 2 is pivoted on the one hand at the free end of its link 3 to a fixed pivot pin 12 rigid with the wall 13 to which the blind is to be mounted, and on the other hand, at the free end of its link 4, to a vertically movable pivot pin 14.
  • This pin 14 is carried for example by a runner adapted to move within a slideway l5 and constantly urged by spring means in the upward direction.
  • the elements 2 are constantly responsive to a force tending to keep them in their unfolded position.
  • this circular arc can be varied to a considerable extent by disposing the pivot pins 16 in holes more or less spaced from the middle point of their corresponding links 3, 4. It is also possible, according to the same circumstance, to impart to these elements 2 firstly a curved configuration followed by a rectilinear section, or vice-versa. Obviously, several shapes and combinations may thus be obtained at will.
  • these blinds were equipped with lateral panels as shown at 17 in FIG. 4, these may be carried by means of eyelets l9 engaged on stub extensions of rods 8. However, when the blind is not fully expanded or unfolded these panel 17 show insightly folds between adjacent rods 8. These folds can be eliminated by using a small cord l8 running along and through the upper edge of the panel of which they engage the eyelets 19 as well as other eyelets 119a each disposed in the vicinity of the upper edge of said panel and centrally of the canvas section extending between adjacent rods 8.
  • the side panels 17 will have a better appearance, as clearly shown in FIG. 4, in which two panels, i.e., a stretched one thick lines and a slack one dash and dot lines, are superposed.
