CHERUBIN COLLAPSIBLE CANOPY Filed Dec. 17, 1962 III l N VEN TOR Pefek CZL/Ulfl United States Patent 3,134,426 COLLAPSIBLE CANOPY Peter Cherubin, Sinn (Dillkreis), Auf der Hardt, Germany, assignor to Dr. Hans-Joachim Kriiger, Sinn (Dillkreis), Germany Filed Dec. 17, 1962, Ser. No. 245,232 Claims priority, application Germany Dec. 18, 1961 4 Claims. (Cl. 160-81) This invention relates to collapsible canopies and the like such as sun blinds mounted on upright supports such as walls.

Known collapsible canopies necessitate the operator clearing a space beneath the canopy to provide room for moving parts of the canopy as it is collapsed or opened or to provide room for the operator while collapsing or opening the canopy.

The main object of the present invention is to provide an improved collapsible canopy which can be collapsed or opened without necessitating the clearance of any space beneath it.

According to the present invention a collapsible canopy comprises a mount for securing to an upright support, a carrier hingedly secured to said mount to pivot thereon in a substantially horizontal plane and having vertically spaced substantially horizontal projections with spaced apertures therein, a number of frame elements each having a pair of arms secured together at one end with their free ends urged apart, journals on the free end portions of said arms and engaged in the apertures in said projections with the axes substantially perpendicular to the projections, rods supported by the frame elements, and an awning of flexible material extended over said rods.

The canopy is preferably constructed with the rods and frame elements or struts which support them positioned in the carrier on axes perpendicular to the plane of the canopy, and the carrier itself is positioned likewise in a mount or bracket serving to fasten the canopy to the upright support e.g. a Wall, so as to pivot on an axis parallel to the said axes, and each strut preferably has a journal which may be introduced into the carrier apertures from above and below respectively, and both journals are resiliently urged in opposing directions into said apertures. Preferably each journal consists of one or both ends of a U-shaped wire forming the struts.

The advantage of the canopy of the invention is that it can be folded up in the plane of the canopy. The ability of the carrier to be swivelled on the mount makes it possible to fold the canopy up in a confined space to lie parallel to the wall, so that it is protected from rain by most of the existing projections on the wall above it. Preferably, two swivelling axles or journals are provided one at each end of the carrier which may be used at will in order to fold the canopy towards one side or the other depending on the available room. It is not necessary to clear a space beneath the canopy as in conventional canopies having an operating handle and/ or a footing on the ground. The canopy may be generally semi-circular with a radius which may be greater than its height above the ground.

The rods may be removed quickly from the carrier whenever the canopy is no longer in use or the awning eg of fabric is to be cleaned. In order to facilitate cleaning the fabric, it is secured to the rods by pockets, one for each rod spaced along its peripheral edge portion and has a lug in its centre which may he slid over a peg or pin secured to the struts. In addition to this, loops can be provided for fastening the fabric along the rods which can be easily undone. Thus the entire fabric of the awning can be removed after folding up the canopy and removing the lug from the peg of the carrier.

In order that the invention may be more clearly under- 3,134,426 Patented May 26, 1964 "ice stood an embodiment in accordance therewith will now be described by way of example with reference to the accompanying drawings in which:

FIG. 1 is an underneath plan view of an opened py;

FIG. 2 is a radial cross section along the line H-II of FIG. 1 looking in the direction of the arrows;

FIG. 3 is a partial cross section through the carrier, and

FIG. 4 is an underside plan view of the folded canopy.

In the figures the same references are used to designate the same parts.

Referring to the drawings these show a collapsible canopy mounted on a vertical support, e.g. a brick wall; the canopy has a mount shown as a bracket 19 fixed to the wall, a carrier 8 hingedly secured to the mount with vertically spaced substantially

horizontal projections

10, 11 having apertures therein, a number of frame elements shown as struts 9 each having a pair of

arms

15, 16 carrying journals 17, 18 on their free end portions engaged in said apertures, rods 2 supported on the upper rod arms 15, and an awning or cover 1 secured to the rods.

The awning is preferably of fabric and the rods 2 are preferably as shown of bamboo canes. For fixing the awning 1 on to the rods 2, pockets 3 are sewn at corresponding distances on to the underside peripheral portion of the awning. The edges 4 of the awning 1 are folded over to form a loop, thereby forming additional elongated pockets for the outermost rods 2. On the underside of the awning 1 a few loops 5 are sewn on, which are preferably provided with press buttons to fix them round the rods. These loops prevent the awning from lifting up when opened out during high winds. A lug 6, is fitted in the centre of radius of the awning for securing and tightening the awning on the frame elements, the lug being slid over a peg 7, located on the carrier. The entire awning 1 may be removed from the rods 2 when the canopy is folded up as FIG. 4 if the lug 6 is raised from the peg 7.

The peg 7 is disposed in the carrier 8 which is generally in the shape of a horse shoe in vertical cross section, its arms or

projections

10 and 11 being reinforced by a web 12. In FIG. 1, the

projections

10, 11 are each shown in outline as an obtuse angle triangle, and have seven apertures along the edge portion 13. Each rod 2 is fastened on to its strut 9 with two clips and consists of a steel wire loop bent over at an acute angle, the arms thereof being shown at 15 and 16. The ends 17, 18 of each strut arm are bent over so that they are co-axially or approximately so. The ends 17, 18 are placed in the apertures 13 of the

arms

10 and 11 respectively and serve as rotary axles or pivots for the struts and thus also for the rods 2. The

arms

15, 16 are urged apart into the aforesaid position and their free ends can be pressed together, to remove them from these apertures, thus facilitating assembling or dismantling of the struts and the rods.

The carrier 8 is pivoted on the bracket 19. This bracket, substantially of plate form, has

projections

20 and 21 respectively at each end at the top and bottom, with

apertures

22, 23 respectively therein, which are coaxial With the outermost apertures 13 in the carrier 8. One of the

bores

22, 23 receives the journal 17 or 18 of one of the two outermost struts 9, whilst the journals 17, 18 of the other outermost strut are shortened to such an extent that they cannot engage in the

apertures

22, 23 respectively. In FIGS. 1 and 4 the journals 17, 18 pass through the apertures 22 of the shank 20. The canopy can thus be folded up about the axis of the aperture 22 to the position shown in FIG. 4.

Further lugs 24 are fitted at the ends of the awning 1, so as to be able to fasten the external rods in hooks 25, fitted to the wall.

A generally semi-circular canopy is shown in the drawings. The canopy may however also be a segment of a circle with an apex angle of less or more than 18 0 degrees, for instance, it may form an angle of 90 degrees so as to be able to fit in a wall rack. In such case-the bracket 19 is in the form of an angle iron.
