This invention relates to collapsible canopy structures.

An object of this invention is to provide a collapsible canopy structure in which the U-shaped bows each have a two section crossbar extending between the side bars, with the outer ends of the crossbar being pivoted to the side bars and the inner ends of the crossbar being connected together for hinged movement from the position of axial alignment to a collapsed position.

An object of this invention is to provide a collapsible canopy structure wherein the hingedly connected inner ends of the two section crossbar of each U-shaped bow when swung to the axial alignment position are releasably locked together.

A further object of this invention is to provide a collapsible canopy structure wherein stop means is provided on the hingedly connected inner ends of the two section crossbar of each U-shaped bow for limiting the hinged movement to the axial alignment position.

The above and still further objects and advantages of the invention will become apparent upon consideration of the following detailed description of the invention, when taken in conjunction with the accompanying drawings, wherein:

Figure 14 is a sectional view taken along the line 14-! 4 of Figure 13.

Referring now more particularly to the drawings, wherein like reference numerals have been used throughout the several views to designate like parts, in accordance with the invention a protective hood It! for a boat ll embodies a plurality of U-shaped bows l2 operatively connected together for movement from a position in spaced confronting relation with respect to each other to an extended or expanded position, Figure l, in diverging relation with respect to each other. Since each of the bows I2 is of like structure, it will suflice to describe only one in detail.

Each of the bows l2 embodies a pair of straight side bars l3 and I 4 disposed in spaced, parallel relation with respect to each other, and a twosection cross bar 15 disposed transversely between the side bars I3 and I4 with opposite ends thereof pivotally connected to the side bars 13 and M at their outer ends by pins Iii. As clearly shown in Figures 5 and 6, a locking hinge 20 pivotally connects and is disposed between the two sections H and H of the crossbar i5, whereby movement of the side bars I3 and I4 toward each other collapses the crossbar l5 inwardly into a position between the side bars 13 and I4, as illustrated in phantom lines in Figure 4. l

The locking hinge 29 illustrated in Figures 5 and 6 comprises a first plate or disc 2! fixed ec centrically on the adjacent end of the section If of the crossbar l5 and a bifurcated second plate or disc 22 fixed eccentrically on the adjacent end of the section I! of the crossbar I5. The plate 2| is received within the bifurcation of the plate 22 and is disposed in abutting and confronting relation with respect to the latter, the plates 2! and 22 being operatively connected together by a hinge pin 23 which extends transversely through the plates and pivotally connects the sections H and I? together for movement from an extended bar it? is -ado'cking*sleeveifa, thesleeve having on one end, Figure 5A, a notch 26 which, when the sections ii and ii are in the end-to-end aligned position, is in alignment with the-slots Z l ofthe plates 2i and 22. To look the sections i1 and l'i in the end-to-end aligned position; the sleeve 25" is rotated sufficiently to causevthe end-portion adjacent the notch 26 to engage the registering slots 25 of the plates 2% and 22, as shown' inFigures 5 and 6. Fixedly secured to the section i? is a'stop lug2?

In Figure there is shown a modified form of the locking hinge means illustrated in Figures 5"-and:6. In'zthe modified forrn, thesleeve provided witlrthe'endnotchtt" and slot and the stop 27 is replaced by a sleeve 5" which is circumposed about the section ll of the cross bar l5'andis inounted on the latter for longitudinal movement into and out of engagement with the registrableslots-M provided in the plates ti and Error-docking the-sections l1 and ii in the extended position. O'peratively connected to the lockingsleeve 55 is a spring 55 which normally biases the sleeve 55 into engagement within the registrable slots 2 5; as-clearly shown in Figure 10. The securement of the spring 55 to the locking sleeve 'andto thesection-i'l is effected. by means of a transversely extending pin 5? which is can ried by the section li'and secured to oneend of the sprin Theother end of the spring, abuts against the-shoulder 58 provided on the sleeve 5% and thereby urgesi-the-sleeve into engagement withinthe registrable; slots-2-l-: When the see-- tions ii and. ll are towbe: collapsed to theposition illustrated in phantom .lines in Figured, the sleeve iit is manually, grasped and urged'away;

It is to he noted that thelocking hinge 2E3 employed in the several forms of thew-collapsible:canopy structures ofrthe' present inventionv-mayhe orthe type employing the slottedlocking sleevev 25- or the spring-biased locking sleeve 55;.

Referring now to Figures 13 and-i l; there is shown an: awning 10'- constructed according; to the present invention: 7 The awning; embodies; at least two bows l2, each including either type-oi the locking hinge means m; The free endsoi the side bars l3 of thebows l2- are connected togetherby an assembly similarto the one illustratedin Figure 2Jand'iincluding thetb'olt 34, the clamping plate 35, the spring 39 and the wing nut 40. It is to' be'noted, however that'itlie clamping plate '35 isadapted for 'securement to the window frame ll on one side of the window frame; Similarly; the free ends- 0f the side: bars' M of the bow 12 are connectedtogether byian assembly including bolt 34, clamping plate 36, the spring 42 and the wing nut '43, the clamping plate 36 being adapted to be secured to the window .frame H at a point opposite the point of securement for the clamping plate 35. Secured on the bows I2 is an awning cover 12 which is drawn taut when the ribs are in their extended position at right angles with respect to each other. In the awning 10 either the type of locking hinge including the slotted sleeve 25, or the type including the spring-biased sleeve 55 may be em ployed.

From the foregoing, it is readily apparent that numerous other modifications of the collapsible canopy structures of the present invention can be made without departing from the spirit of the invention as set forth in the appended claims.

What I claim is:

1. In a collapsible canopy, at least two U- shaped bows each comprising a pair of laterally spaced side bars, and a two-section crossbar extending between the side bars, the sections of the crossbar being in axial alignment in the expanded condition of the canopy, the sections of the crossbar having laterally outward ends pivoted to the side bars at one end thereof, the other ends of the side barsat each side of the bows being adapted to be mounted on a support, a cover secured over the bows and extending therebetween, and locking hinge means located between and connecting the laterally inward ends of the crossbar sections, comprising plates fixed on the laterally inward ends of the crossbar sections, a pivot pin traversing said plates and connecting the plates for hinged movement relative to each other, and locking means on one of the crossbar sections engageable with the said plates for releasably locking the crossbar sections in Number axial alignment, said locking means comprising radial slots formed in said plates and arranged to register with the sections in alignment, and a sleeve circumposed on one of the crossbar sections and movable thereon, said sleeve having an end arranged to engage in the slots when registered so as to lock the crossbar sections in alignment.

2. The collapsible canopy according to claim 1 including in addition a stop lug on said one sec tion of the crossbar engaged in a slot formed in the other end of said sleeve for holding said sleeve against longitudinal displacement on said one section of the crossbar and for limiting the rotary movement of said sleeve.

3. The collapsible canopy according to claim 1 including in addition a spring operatively connected to said sleeve for normally biasing said one end of said sleeve into engagement with the slots when registered.
