Application April 30, 1956,- Serial 131015815646 1 Claim. c1. 135-5 The present invention relates to-sunshades, and more particularly a canopy typesun'shade for' use on lawns, beaches, over pools, and the like.

The primary object of tlie invention ate-provide a sunshade of the canopy typewhich can -be-collapsed into a relatively small package without the use of tools.

Another'objectof'the' invention is to provide a; sunshade of the canopy" type having a of supporting rn'e'nibersto permit relatively unobstructed use of the canopy without interference from. supporting members.

A further object ofthe invention is to provide a sunshade 'of the canopy-type 'a's dscrib'ed above -which will be inexpensive to manufacture, simple to use and adjust, and durable in service.

Other objects and advantages will become apparent in the following specification when considered in the light of the attached drawings, in which:

Figure 6 is a fragmentary inside elevation of one end of the sunshade.

Figure 7 is a fragmentary enlarged vertical cross-section taken along the line 77 of Figure 6, looking in the direction of the arrows.

Figure 8 is a plan view of one of the canopy supports shown partly broken away for convenience of illustration.

Figure 9 is a fragmentary side elevation of one of the winding journals.

Figure 10 is an enlarged fragmentary cross-section taken on the line 1010 of Figure 8, looking in the direction of the arrows.

Referring now to the drawings in detail wherein like reference numerals indicate like parts throughout the several figures, the reference numeral 10 indicates generally the sunshade constructed in accordance with the invention. The sunshade 10 has a pair of

upright supports

11 and 12 formed of tubular material. The upright 12 is provided with a right angularly extending journal bearing 13 which is welded to the top of the support 12 and extends transversely thereof, as best illustrated in Figure 3.

A web brace 14 is positioned between the upright support 12 and the bearing 13 to serve as a reinforcement. The upright support 11 is provided with a transversely extending journal bearing 15 welded to the upper end of the support and additionally connected thereto by reinforcing 2,844,156. Patented July 22, 1958 web 16,- similartothe web 14. An elongated tubular drum 17 is journalled at its opposite ends in the journal bearings 13 and 15 and is adapted to be rotated therein by means of "a hand crank 18 secured toone end of the drum 17 by means of clamping nuts 19 and 20. A pulley 18a is associated with the'hand crank 18 and has a rope 18b loosely trained thereover so that the drum 17 may be rotated by either the rope 18b or the crank 18.

A-p'air of

collars

21 and 22 are secured to the drum 17 in; spaced apart parallel relation adjacent the journal bearing13, for reasons to be assigned.

A' pair of downwardly and outwardly diverging

braces

23 and 24 are secured to the upright support 11 by means of a'bolt25 extendingth'rough the upper ends of the brace membersx23=and 24 and through the supportmember 11. A cross brace 26 has-its opposite endssecured to medial points on the

braces

23 and 24 and is secured to the uprightsupport. 11-. intermediate its ends by means of a bolt 27- which extends through the support-11 and through a.

reinforcingangle: iron brace 28 through the cross brace 26 and is secured in place by a nut 29;

Apair of :

angle irons

30 and 31 are secured to the support l -1'10 extend-longitudinally thereon so that the outer l'egsroflthe angle-irons 30and 31 are parallel to each otl'ier and spaced apart,- and the inner legs of the

angle irons

30 and 31 are positioned in confronting relationlying in the same plane and spaced from each other to form a slot 32 therebetween.

The upright support 12 is provided with a pair of angularly extending braces 23' and 24 having their upper ends secured to the support 12 by means of a bolt 25.

-An angle iron cross brace 26 is secured at its opposite ends to medial points on the braces 23' and 24 and is secured to the upright support 12 by means of a bolt 27 which extends through the support 12, an angle iron reinforcing plate 28, and a cross brace 26'. A nut 29' secures the bolt 27 in position.

Angle irons

30 and 31 are mounted longitudinally to the support 12 in the same manner as the

angle irons

30 and 31 are mounted to the support 11 providing a slot 32 therebetween.

The drum 17 is provided with a pair of spaced

collars

21 and 22 adjacent the bearing journal 15, for purposes to be described. A pair of

canopy bows

33 and 34 are formed in a general Ushape and are provided with flattened

free end portions

35, 36, 37 and 38, respectively. The

bows

33 and 34 are formed of several pieces connected by

couplers

33a and 34a, as best illustrated in Figures 8 and 10. The flattened end portions 35 and 37 have a bolt 39 extending therethrough with a head 40 on the bolt engaging under the

angle irons

30 and 31 so that the bolt 39 extends outwardly through the slot 32'.

Washers 41 and 42 are carried by the bolt 39 and engage opposite faces of the

angle irons

30 and 31. A nut 43 is positioned on the bolt 39 and serves as a seat for the flattened portion 35, as best illustrated in Figure 5. A nut 44 secures the flattened portion 37 onto the bolt 39 and is adapted to secure other elements thereon to be described.

An identical bolt 39 is utilized to secure the

flattened portions

36 and 38 to the

channels

30 and 31 in the same manner as described above for the opposite end of the canopy.

A rectangular canopy 45 is secured along its midline at 46 to the drum 17. The outer edges of the canopy 45 are secured at 47 and 48 to the

bows

33 and 34.

A chain 49 is engaged at its lower end over the bolt 39 where it is secured by the nut 44. The opposite end of the chain 49 is wrapped around the drum 17 between the

collars

21 and 22 and has its terminal end portion secured to the drum 17, for purposes to be described.

A chain 50 is secured to the opposite bolt 39 in the same manner as the chain 49 and has its opposite end wrapped around the drum 17 between the collars 22' and 21 with its terminal end secured to the drum 17 in the same manner as the chain 49.

Hooks 51 are secured to the

cross bars

26, 26, or to any other desired points within the canopy 10 to provide a support for hammocks, swings, and the like.

In the use and operation of the invention, the canopy 10 is set up with the

upright supports

11 and 12 braced by their

respective brace members

23, 24, 23' and 24', as illustrated in Figure 1. When it is desired to fold the canopy due to inclement weather, night time, high winds, or for storage, the crank 18 is rotated rotating the drum 17. The canopy 45 will be wound upon the drum 17 from opposite sides and simultaneously therewith the chains 49 and 50 Will be unwound permitting the

bows

33 and 34 to move downwardly with respect to the

supports

11 and 12 to a position illustrated in Figure 2.

When it is desired to open the canopy for use as a sunshade, the crank 18 is rotated in the reverse direction, unwinding the canopy 45 and winding up the chains 49 and 50, pulling the

bows

33 and 34 to a horizontal position, as best illustrated in Figure 4.

Having thus described the preferred embodiment of the invention, it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the scope of the appended claim.

What is claimed is:

A sunshade canopy comprising a pair of spaced parallel upright members, a journal bearing mounted on the upper end of each of said upright members, said journal bearings having their axes aligned, an elongated drum extending between and journalled in said bearings, a pair of oppositely extending U-shaped bows, a vertically extending trackway secured to each of said upright members, a guide bolt vertically slidable in said trackway, said guide bolts each having one end of each of said bows journalled thereon, a flexible member at each end of said drum having one end fixed to said drum and the opposite end fixed to one of said guide bolts whereby on rotation of said drum in one direction said flexible members are wound thereon raising the ends of said bows supported on said guide bolts, a canopy secured medially to said drum, said canopy having its opposite free end edges secured to the opposite bight portions of said bows, and a hand crank secured to said drum.
