Detailed Description of the Preferred Embodiments
Referring to FIGS. 1 and 2, there is shown an elongated deck chair framework with adjoining leg rest, seat and back rest portions 2, 4, 6, provided with a cover assembly according to the invention. The cover assembly is particularly useful to protect a user lying down on the deck chair from sun rays, rain and wind whatever their origin with respect to the chair. It will become apparent from the following description that the cover assembly is designed so that it can be either added to an existing deck chair or integrated therewith during its manufacturing, and that it combines with the chair framework to form an easily portable, foldable arrangement.
The cover assembly basically comprises a roll of fabric 8 which, when unrolled and stretched over the chair framework, is adapted to protectively cover a user lying down on the leg rest, seat and back rest portions 2, 4, 6. The roll of fabric 8 is rotatably mounted onto a front end of the leg rest portion 2, transversely with respect to the chair framework, by means of a rotatable shaft 10 extending between upper portions of roll supporting brackets 12, 14. The roll supporting brackets 12, 14 have lower portions secured onto respective sides of the chair framework by means of bolts 16. Any other convenient securing elements could also be used to secure the roll supporting brackets 12, 14. The brackets 12, 14 can take any suitable shape, and could be solid with the chair framework if the deck chair is initially manufactured with the cover assembly.
Referring to FIG. 6, the shaft 10 can be conveniently provided with a rewind mechanism 18 like in a blind, causing the roll of fabric 8 to automatically rewind when not stretched. Otherwise, the user would have to rewind the roll of fabric 8 using a suitably arranged crank or in a direct manual manner.
Referring back to FIGS. 1 and 2, the cover assembly also basically comprises a support 19 in the form of a U-shaped support pole 20 having lower ends forming the base of the support 19, on respective sides of the chair framework. The lower ends of the support pole 20 are pivotally connected to upper portions of mounting brackets 22, 24 having lower portions secured onto respective sides of the framework at or near the junction of the seat portion 4 with the back rest portion 6, by means of bolts 27.
The support pole 20 is locked in a fixed angular position with respect to the seat portion 4 by means of a pair of cotters 29 inserted in coaxially alignable bores through the lower ends of the support pole 20 and the upper portions of the mounting brackets 22, 24, shifted from a pivot axis of the support pole 20 with respect to the mounting brackets 22, 24. The cotters 29 are provided with a handle 30 to facilitate their use.
The support pole 20 can thus be upwardly mounted onto the chair framework at a remote location away from the roll of fabric 8. The upper part of the support pole 20 is shaped to provide at least one attachment point for a free end 32 of an unrolled part of the fabric 8 (as shown in FIG. 3), at a desired height above the chair framework. Since the purpose of the support 19 is to provide such an attachment point for the free end 32 of the fabric 8, the support 19 could take many other shapes. For example, it could consist of two straight poles upwardly mounted onto respective sides of the chair framework, with the upper portions of the straight poles providing the required attachments points. It could also consist of a single straight pole upwardly mounted on one side of the framework, provided with a cantilever pole connected to an upper end of the straight pole and extending over the chair framework. Instead of using cotters 29 and bores, the mounting brackets 22, 24 could be easily arranged to form vises that clamp the lower ends of the support pole 20 between the plates of the brackets 22, 24, in order to hold the support pole 20 in position. Such a vise arrangement could be especially useful to permit an angle adjustment of the support pole 20 with respect to the chair framework.
Many manners can be adopted to detachably attach the free end 32 of the fabric 8 to the upper part of the support 19. For example, VELCRO (synthetic materials which adhere when pressed together) elements 34 can be positioned at the desired height onto the upper part of the support pole 20 to fasteningly receive corresponding VELCRO elements 36 at the free end 32 of the fabric 8.
An optional roof accessory 38 may be affixed to the cover assembly to cover the back rest portion 6, and provide the user with additional shade or rain protection. The roof accessory 38 includes a U-shaped roof pole 40 having front ends pivotally connected to the upper part of the support pole 20 on a back side thereof, by means of hinge brackets 42, 44. These hinge brackets 42, 44 permit the deployment and holding of the roof pole 40 perpendicularly to the upper part of the support pole 20 when in use, and its folding next to the support pole 20 for transportation and storage of the deck chair, as shown in FIG. 5.
Referring to FIG. 3, the roof accessory 38 has a top fabric 46 covering an area delimited by the roof pole 40. The top fabric 46 is detachably fastened on the roof pole 48 by means for example of VELCRO strips 48 (shown in FIG. 1).
The roof accessory 38 may conveniently further include a side screen of fabric 50 laterally covering an area extending behind the support pole 20, between the roof pole 40 and the framework under the roof pole 40, around the back rest portion 20, to provide lateral wind protection at the level of the back rest portion 6. The side screen of fabric 50 can be detachably connected to these structural elements by means of VELCRO strips 52, 54, 56, so that side flaps 60 can be doubled over for air circulation or to talk to a neighbour.
Optional side accessories 58 can be provided to protect the user from lateral wind at the level of the leg rest and seat portions 2, 4. The side accessories 58 are formed of screens of fabric 60 hanged by elastic cords having ends provided with hooks 62 for detachable attachment to the support pole 20 at a desired height thereon and to the front end of the leg rest portion 2 on respective sides of the chair framework.
Referring to FIG. 4, there is shown the deck chair where the accessories 38, 58 of the cover assembly are in withdrawn position. The side accessories 58 can be used as pockets 64 when attached at the level of the chair framework.
Preferably although not restrictively, the fabric used in the cover assembly is canvas that can be provided with optional windows.
Referring to FIG. 1, the leg rest, seat and back rest portions 2, 4, 6 of the framework are formed of tubular members interconnected by means of hinge brackets 22, 24, 26, 28 so that the leg rest and back rest portions 2, 6 are foldable over the seat portion 4. The framework is provided with U-shaped tubular legs 66, 68, 70, 72 having ends pivotally connected to the hinge brackets 22, 24, 26, 28, the roll supporting brackets 12, 14, and a tubular head portion 74 of the framework for downward deployment. The back rest portion 6 is locked in a fixed angular position with respect to the head portion 74 by means of a pair of parallel arms 76, 78 having upper ends pivotally connected to the back rest portion 6 on respective sides thereof, and lower ends between which a transversal rod 80 extends. The transversal rod 80 has extended ends 82, 84 projecting beyond the arms 76, 78 which are inserted in two series of upwardly directed notches 86, 88 provided on respective sides of the head portion 74. The notches 86, 88 can be provided with suitable locking elements (not shown in the Figures) to prevent unwanted removal of the extended ends 82, 84 therein.
Referring to FIG. 5, there is shown the deck chair with the cover assembly, in a compact folded arrangement. The chair can be carried just like a briefcase, using the roll of fabric 8 as a handle. Thus, a user can bring the folded deck chair to the beach instead of a parasol and/or a regular deck chair. In the compact arrangement, the leg rest portion 2 is folded about the brackets 26, 28, and placed next to the seat portion 4 which is itself folded about the mounting brackets 22, 24 and placed next to the support pole 20 of the support 19. The arms 76, 78 and transversal rod 80 are folded next to the back rest portion 6 which is itself folded in alignment with and inside the support pole 20. The roof accessory 38 is folded about the brackets 42, 44 next to the support pole 20. Finally, the head portion 74 is folded about the mounting brackets 22, 24 next to the roof accessory 38, with the legs also folded inside the head portion 74.
While embodiments of this invention have been illustrated in the accompanying drawings and described above, it will be evident to those skilled in the art that changes and modifications may be made therein without departing from the essence of this invention. All such modifications or variations are believed to be within the scope of the invention as defined by the claims appended hereto.
