RETRACTILE AwNING Filed Oct. 1, 1957 2 Sheets-Sheet 2 3,002,555 RETRACTILE AWNING Simon Goldiarh, Esmeralda 675, Buenos Aires, Argentina Filed Oct. 1, 1957, Ser. No. 687,585 1 Claim.. (Cl. 160-62) The present invention relates to a retractile awning. More particularly, the present invention is concerned with the provision of a novel pantographic mounting which carries its component boar'ds for relative displacement as controlled by a network formed from a series of scissors.

Itis an object of the invention to provide an improved awning construction and, to this end, the invention contemplates an awning comprising generally horizontal and parallel lazy tong arrangements, each including sets of oppositely inclined ribs and means pivotally connecting the ribs to constitute said arrangements. The ribs of one set include portions extending upwardly beyond the ribs of the other set and iirst and second pivots are provided on each of said portions. Slats are furthermore provided in accordance with the invention extending between the above-noted lazy tong arrangements and connected to respective of said iirst pivots. Moreover, pivots are additionally provided on the slats with rods connecting these latter pivots to the second pivots on the above-noted portions. Each slat and the rod associated therewith is connected to the irst and second pivots respectively on adjacent ribs of one of the sets of ribs noted above. Furthermore, fixed vertical rails are provided in correspondence with the lazy tong arrangements. In addition, means are provided pivoting the sets of ribs of the lazy tong arrangements to their respective rails. The latter said means is xed relative to said rails. In addition, means are provided which are slidable on the rails and which are connected to the other of the sets of lazy tong arrangements and springs are provided engaging the slidable means for purposes of balancing in part the weight of the slats and lazy tong arrangements.

In order that the invention may be clearly understood and readily carried into el'ect, it will now be described more fully with reference to the accompanying drawings in which:

FIG. 1 is a side view of the awning in fully extended condition;

FIG. 2 is a side view of said awning in retracted position;

fFlG. 3 is a side view of the awning in an intermediate position between the fully expanded condition of FIG. v1 and the fully retracted condition of FIG. 2; and

FIG. 4 is a perspective view of part of the awning in its extended condition.

In the various figures of the drawings the same reference numbers indicate the same or corresponding parts, the dilerent elements being indicated by letters.

A s may be seen in the drawings, a are the slats or boards which are in the form of segments and constitute the retractable awning, the base of which is iirmly set in the wall 1.

The front portion of the boards a have a ange 2 provided with a downwardly bent portion and the rear portion of each board is provided a `llange 3 bent in an upwardly direction relative to the downwardly bent portion so that when the boards are displaced, the ilanges 2 and 3 are engaged with each other, thus limiting the spreading or extended condition to the position shown in FIGS. 1, 3 and 4.

Boards a at their rear part are provided with a pair of ears 4, and intermediate the ends of the boards a there is provided at the underside thereof a pair of ears 5, thus forming articulation or hinge points with the lazy tong arrangements or post b.

nitedStates Pate" network series with the iirst set of base elements dei-inedby ribs 6 and 7 in support a, for ribs 6 is articulated in or hinged to pin 8 while rib 7' is articulated by or hinged to pin 9 on slider 10 which is movable along the vertical rail 11 of support c.

The pair of supports a support a pair of journal bear.-

ings 12 which carry cross bar 13 and from which arms: 14 extend and are projected towards the front so as tot.

articulate or form a hinge connection with ribs 15 through pin 25. The other ends of said ribs 15 are articulated in or hinged to pin 26 corresponding to the articulation or hinge of the rst rib 7' and the second rib 6 which follows rib 6 in each pantographic mounting.

The extreme ends of the rods of mounting b are also coupled to two dual ribs 7 at one end and at their other ends to crossbar 16. Said crossbar 16 also possesses a hooked indentation 16 (see FIG. 4) through which may be eiected the operation of the opening or closing of the pair of mountings b.

The boards a not only rest on the pair of posts b but are joined to the same by means of articulations or hinges connected to the rear ears 4 and intermediate ears 5.

Each end of ribs 6 of the pantographic post b, apart from its parallelogram type of hinge connections, possesses two hinge pins or pivots 17 and 18, of which pin 17 engages ear 4 of the associated board a while the second hinge pin 1'8 is hinged to ear 5 of another board immediately above and coupled by means of a connecting rod 19 at one end thereof to ear 5 and at the other end of rod 19 to pin 18. In this manner each board a is joined in direct manner with its hinge pin 17 to a rib 6 of post b, while on the other hand it joins in indirect manner through connecting rod 19 to another rib 6 of said post b.

The direct connection of hinge pin 17 controls the position of its associated board a with respect to rib 6 of pantograph b by what is referred to as the mutation angle of pantographic position. It will also be noted, however, that connected to each pivot 18 is a connecting rod 19 which also exerts a control. The variations are different as may be clearly seen in FIG. 3.

The extended position of the awning (FIG. 1) is limited by the stops or anges 2 and v3; the post b with its direct hinge pin 17 determines the essential rest point of boards a while hinge pin 18 and connecting rod 19 determine the slope of the boards, a second rest resulting at the intermediate line dened by pins 20 of ears 5. Furthermore, the connecting rods '1-9 act to prevent the wind from damaging the boards.

The runner 10 is pressed by compression springs 21 and 22 which are wound on the Vertical rail 11 Where the runner operates; the rst spring 21 is supported on the top part of runner 10 and presses the runner downwards, thus tending to fold the pantographic posts b of the awning; while spring 22, resting on plate 23 in the lower part, presses the runner 10 upwards. The pressure of both these springs is such that the weight of the awning and its posts are compensated and balanced in its different positions. This establishes such an equilibrium that operating the device by indentation or hook 16 of the crossbar 16 does not require any effort.

The front part, that is board a corresponding to the free end of the awning, supports a plank 24 covering part of the mechanism in open position (FIG. l) or in the closed position.
