## Background
PRIORITY CLAIM
This application claims priority to French Patent Application No. 0951999, filed Mar. 30, 2009.
BACKGROUND
This present disclosure relates to devices for protection against the sun or inclement weather, such as sunshades, for example, sunshades for strollers or other child care equipment, umbrellas, or parasols.
In the field of the present disclosure, there are many types of parasols, umbrellas, or sunshades, each of these devices comprising generally a cloth, a shaft, and umbrella ribs. In position of use, the umbrella ribs are generally separated from one another and make it possible to stretch the cloth when the sunshade is unfolded.
Sunshades are in general able to occupy an unfolded position of use and a folded storage position. The storage position is often compact around the shaft of the sunshade. The shaft is even sometimes telescopic in order to further improve the compactness of the sunshade in storage position.
SUMMARY
A sunshade in accordance with the present disclosure includes a canopy and a central pole under the canopy. The canopy includes a fabric cover and a frame coupled to the central pole and to the canopy. The frame is movable relative to the central pole between collapsed and expanded positions to furl and unfurl the fabric cover.
In illustrative embodiments, the frame includes four fabric-support branches. Each branch widens along its length in a direction away from the central pole. Each branch includes a pair of ribs that are arranged to lie in diverging relation to one another as they extend away from the central pole and a relatively wide laterally extending rib spreader coupled to outer ends of the ribs. The rib spreader includes an outwardly presented exterior edge having a convex shape and lying along and in substantially coextensive relation with a curved corner segment of a perimeter edge of the fabric cover.
In illustrative embodiments, the canopy further includes several mount portions coupled to an underside of the fabric cover along the perimeter edge thereof. Each mount portion cooperates with the fabric corner to form a pocket receiving therein the relatively wide rib spreader of one of the fabric-support branches. Each rib spreader is constrained to remain in its companion pocket in each of the collapsed and expanded positions of the frame and during movement of the frame relative to the central pole between the collapsed and expanded positions.
Additional features of the present disclosure will become apparent to those skilled in the art upon consideration of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.

DETAILED DESCRIPTION
A stroller P whereon has been fixed, for example, by clipping according to the double arrow, a sunshade 1 in accordance with the present disclosure is shown as suggested in FIG. 1. A fastening member O is coupled to stroller P and configured to mate with sunshade 1 to support sunshade 1 on stroller P as suggested in FIG. 1. Any other system of fastening the sunshade on the stroller can be considered and is within the scope of the present disclosure. Closure, folding, and storage of an illustrative sunshade 201 in accordance with the present disclosure is shown, for example, in FIGS. 10-13.
In FIG. 2, the sunshade 1 is shown in a position of use and unfolded. The sunshade 1 comprises a plurality of umbrella ribs 2 that can be seen in FIG. 3 and a protective cloth 3 made in an illustrative example from fabric. Cloth 3 is arranged to cover the umbrella ribs 2 of a first side corresponding to the top of the sunshade, in the example shown in FIGS. 1-3.
The cloth 3 comprises seams 4 made on umbrella ribs 2, along the latter. The umbrella ribs 2 are indeed not able to be seen directly in FIG. 2, but covered by the cloth 3. The umbrella ribs 2 can be seen in FIG. 3. The umbrella ribs 2 can be made from a metal material, plastic, fiberglass, composite, or other suitable material.
The sunshade 1 further comprises central pole or shaft 15 that can be seen in FIG. 3. For reasons of clarity in the drawing, the shaft 5 has been shown partially truncated. The shaft 5 provides a handle grip at a lower end thereof and comprises, at an upper end thereof, a top 6 wherein are fixed first ends 2a of the umbrella ribs 2 and also the cloth 3 in such a way as to maintain it stretched against the umbrella ribs 2 in the vicinity of the first ends 2a of the umbrella ribs 2. In an embodiment not shown, the top 6 can be located beyond the first ends 2a of the umbrella ribs 2, in which case the first ends 2a of the umbrella ribs 2 are fixed directly in the body of the shaft 5 and not on the top 6 of the shaft 5.
The sunshade 1 can have an unfolded use position as suggested in FIGS. 1-3 or a folded storage position as described further on with regards to FIG. 9. The folding and the unfolding of the sunshade 1 can take place thanks to the presence on the sunshade 1 of counter-umbrella ribs 20 suggested in FIGS. 3, 4, 6, and 8 and shown in more detail in FIG. 10. Each counter-umbrella rib 20 comprises an end 21a which is articulated relatively to a corresponding umbrella rib 2 and another end 21b which is fixed on a ring 22 sliding along the shaft 5 between the folded use position and the unfolded storage position, in order to allow for the reconfiguration of the sunshade 1 from one position to the other. Any suitable counter-umbrella ribs 20 and sliding ring 22 can be included in sunshade 1. As suggested in FIG. 10, a spring-loaded detent 23 included in sliding ring 22 can engage an aperture 25 formed in shaft 5 to retain a frame 30 comprising all of umbrella ribs 2 and counter-umbrella ribs 20 in an expanded position.
The umbrella ribs 2 each comprise, in addition to the first end 2a, a second end 2b that can be seen in FIG. 4, for example. The umbrella ribs 2 are arranged around the shaft 5 by pairs 8, i.e., two by two, being closer to one another in a pair 8 than to any other umbrella rib 2, in particular, another adjacent umbrella rib 2 as suggested in FIG. 4.
The umbrella ribs 2 of a pair 8 are connected by their second ends 2b using a junction element 10 with which they cooperate and which makes possible at the same time to connect the second ends 2b of the umbrella ribs 2 of a same pair 8 and to maintain the latter separated, whether the sunshade 1 is in unfolded or folded position, where applicable. The number of junction elements 10 in a sunshade 1 in accordance with the present disclosure can be equal to the number of pairs of umbrella ribs 2, as in the example shown in FIG. 4.
As can be seen in FIG. 3, the cloth 3 comprises a mount portion 9 covering, in particular, a corner portion of a second side corresponding to the bottom of the sunshade 1 and the second ends 2b of the umbrella ribs 2 as well as the junction element 10. This mount portion 9 can make it possible to fasten the cloth 3 with the second ends 2b of the umbrella ribs 2 of a pair 8, for example, in such a way as to maintain the entire junction element 10 and the second ends 2b and as such minimize the likelihood, for example, that a child will unfasten the cloth 3 from the junction element 10 of the umbrella ribs 2. The presence of this mount portion 9 of cloth 3 can also contribute to the aesthetic aspect of the sunshade 1.
The junction element 10 comprises an added part 11 or 11′ that is provided in addition to each of the ribs 2 as shown in FIGS. 4-7. Junction element 10 is configured to interconnect second ends 2b of adjacent umbrella ribs 2 as suggested in FIGS. 4, 6, and 10.
In this case, the junction element 10 can, as can be seen in FIGS. 4 and 5, comprise an added part 11 comprising a molded plastic part having a convex side 12, in particular rounded, two ends 14 consisting in the example shown of tubular portions located in the extension of the side 12, and an interior structure 13, cut out in the form of a T in the example shown, maintaining the two tubular portions 14 separated. The form of the interior structure 13 could be solid or have another form without leaving the scope of the present disclosure. The ends 14 are intended to be fixed, in particular threaded in the example shown, on companion umbrella ribs 2. As can be seen in FIG. 4, the junction element 10 makes it possible to connect together the second ends 2b of the umbrella ribs 2 of the same pair 8, whether the sunshade 1 is in unfolded or folded position, where applicable.
Another example of a junction element 10 comprises an added part 11′ in addition to companion ribs 2 and has been shown, for example, in the FIGS. 6 and 7. This added part 11′ is a rod in the form of a U of which can be threaded the two tubular ends on the second ends 2b of the umbrella ribs 2 of the same pair 8 in such a way as to connect the latter and to maintain them separated, at a distance from one another, whether the sunshade 1 is in unfolded of folded position, where applicable. The rod 11′ shown in FIG. 7 can also have, when not assembled with the umbrella ribs 2, a rectilinear form, being for example made of flexible material that can take the form of a U when assembled with the umbrella ribs 2. The rod 11′ of FIG. 7 could, in an alternative not shown, comprise ends formed of blind holes making possible the assembly with the second ends 2b of the umbrella ribs 2, the rest of the rod 11′ being, for example, solid and not hollow. The rod-defining junction element 10 could, in an embodiment not shown, comprise a spring.
In the case where the junction element 10 comprises an added part in addition to a pair of companion ribs 2, the latter can consist of a part made of a plastics material such as an elastomer, a metal material, or a relatively rigid fabric, or other suitable material. In another embodiment shown in FIG. 8, the junction element 10 is formed of a single (i.e., monolithic) part with the umbrella ribs 2 of the same pair 8.
The sunshade of FIGS. 2 and 3 is shown in a folded storage position in FIG. 9. As can be seen in FIG. 9, the pairs 8 of umbrella ribs 2 are stacked on top of each other when the sunshade 1 is in folded position, which makes it possible to obtain a flat folding.
In the examples shown, the total number of umbrella ribs 2 is equal to eight and the umbrella ribs 2 all have a substantially equal length, in such a way that the general form of the sunshade 1 is substantially square. It is within the scope of the present disclosure to provide the umbrella ribs 2 with unequal lengths in such a way, for example, as to obtain the general form of a parallelogram such as a rectangle for the sunshade 1 and/or if the total number of umbrella ribs 2 is different from eight, being, however, of an even number in such a way as to be able to connect the umbrella ribs 2 two by two. For example, the total number of umbrella ribs 2 can be greater than or less than eight, for example, be equal to six, in which case the sunshade 1 has a generally triangular form.
The present disclosure is of course not limited to the examples that have just been described. In particular, the present disclosure is not limited to sunshades 1 but to any type of device for protection against the sun and inclement weather, for example, a sunshade, an umbrella, a parasol, or other shield.
According to an aspect of the present disclosure, the sunshade 1 comprises at least one junction element 10 cooperating with one of the pairs 8 of umbrella ribs 2. One of the junction elements 10 is configured to connect the second ends 2b of the umbrella ribs 2 of each pair 8 and maintain at a distance from one another the second ends 2b of the umbrella ribs 2 of that pair 8. The distance between the second ends 2b of the umbrella ribs 2 of a pair 8 can, for example, be maintained, whether the sunshade 1 is in unfolded use position or in the folded storage position. In another illustrative embodiment (not shown), the distance between the second ends 2b of the umbrella ribs 2 of a pair 8 may not be maintained in folded storage position.
As used herein, the expression “at least one portion of the umbrella ribs being grouped by pairs” means that two adjacent umbrella ribs 2 are located at a short distance in relation to one another in relation to the distance that separates each one of them from any other umbrella rib 2 of the sunshade 1. It can further be said (in reference to FIG. 4) that the distance between a first umbrella rib 2-1, at a point of the latter possibly not located in the vicinity of the first end 2a of this umbrella rib 2-1, and the second umbrella 2-2 rib of the same pair 8 (e.g., fabric-support branch 31) is less than the distance between the first umbrella rib 2-1 and an adjacent umbrella rib 2-1 included in an adjacent fabric-support branch 32 and separate from the second umbrella rib 2-2 included in fabric-support branch 31.
The link between the first end 2a of an umbrella rib 2 and the shaft 5 can be direct or indirect within the scope of the present disclosure. This link is able, for example, to be made by the intermediary of a part.
The sunshade 1 can comprise, in addition to the umbrella ribs 2 grouped by pairs 8, one or several umbrella ribs 2 that are solitary or isolated. In this case, the total number of umbrella ribs 2 can be even or odd, according to the number of isolated umbrella ribs 2. When the sunshade 1 does not comprise isolated umbrella ribs 2, but only umbrella ribs 2 distributed in pairs 8, the number of umbrella ribs 2 is even. This structure can make possible, in addition to the advantages already listed, an original and effective folding of the sunshade, wherein the various pairs 8 of umbrella ribs 2 are stacked one in relation to the other.
According to an embodiment of the present disclosure, the junction element 10 can comprise an added part in addition to the companion two ribs 2. In this case, the added part can be arranged in such a way as to be fixed, for example, to thread onto each of the second ends 2b of the umbrella ribs 2 of the pair 8. In this case, the added part can comprise two hollow tubes arranged in order to thread around each of the second ends 2b of the umbrella ribs 2 according to a tube-in-tube link. Any other type of link for the fastening of the added part on the second ends 2b of the umbrella ribs 2 can be considered, the fastening not being limited to a tube-in-tube link. Other examples of fastening that can be considered can be selected from the following: crimping, gluing, overmolding, or an other type of mechanical assembly.
The junction element 10, in particular the added part, can have a convex form, in particular rounded, in such a way that the second ends connected by the added part form a convex angle, in particular, rounded of the sunshade. The added part can comprise a plastics material, in particular, a polymer, such as polypropylene, polyethylene, or a thermoplastic material. The added part can comprise alternatively a rod, in particular a rod made of metal, elastomer, or a sufficiently rigid fabric, among others.
According to another aspect of the present disclosure, the junction element 10 can be made from a single part with the umbrella ribs 2 of a pair 8 forming, for example, a convex angle, for example, rounded, of the sunshade 1. The umbrella ribs 2 can comprise a metal material, plastic, fiberglass, a composite material, or other. The total number of umbrella ribs 2 can be equal to eight.
The umbrella ribs 2 can have lengths that are substantially equal to each other in such a way that the general form of a sunshade 1, excluding possibly rounded angles, can be a square. The square form can make it possible, in relation to a sunshade of generally circular form, to enlarge the protection surface, the circle of known sunshades able to be inscribed in the square of the sunshade according to the present disclosure. The umbrella ribs 2 can have, alternatively, lengths that are not equal to each other in such a way that the general form of a sunshade, excluding possibly rounded angles, can be a parallelogram such as a rectangle.
Sunshade 1 includes a canopy 28 and a central pole 5 under canopy 28 as suggested in FIGS. 1 and 3. Canopy 28 includes a frame 30 mounted for movement relative to central pole 5 between collapsed and expanded positions and a fabric cover 3 coupled to frame 30 to move therewith relative to central pole 5 as suggested in FIGS. 1-3, 9, and 10.
Frame 30 includes several fabric-support branches 31-34 arranged to underlie and support fabric cover 3 in canopy 28 and to extend outwardly away from central pole 5 upon movement of frame 30 to the expanded position as suggested in FIG. 3. Fabric-support branches 31-34 are configured to be moved in inward directions A-D by a user during furling of fabric cover 3 as suggested in FIGS. 10 and 11 to lie generally along the length of central pole 5 when frame 30 is moved relative to central pole 5 to assume the collapsed position as suggested in FIGS. 9 and 13.
A frame 30 in accordance with the present disclosure is shown diagrammatically in FIG. 3 and illustratively in FIG. 10. Frame 30 includes fabric-support branches 31-34. One alternative frame 30′ within the scope of the present disclosure includes fabric-support branches 31′-34′ and is shown, for example, in FIG. 4. Another alternative frame 30′′ includes fabric-support branches 31′′-34′′ and is shown, for example, in FIG. 6.
Frame 30 also includes a slide 22 mounted for back-and-forth sliding movement on central pole 5 and several sets of counter-umbrella ribs 20 as shown, for example, in FIG. 10. Ribs 20 are arranged in pairs and each pair is coupled to slide 22 and to one of fabric-support branches 31-34.
Each of fabric-support branches 31-34 includes an inner root portion 101 and an outer distal portion 102 as suggested in FIGS. 3 and 4. Inner root portion 101 is arranged to lie in close proximity to central pole 5 in each of the collapsed and expanded positions of frame 30 and configured to have a narrow lateral width as suggested in FIGS. 4 and 10. Outer distal portion 102 is arranged to lie in close proximity to central pole 5 upon movement of frame 30 to assume the collapsed position and in spaced-apart relation to central pole 5 upon movement of frame 30 to assume the expanded position. Outer distal portion 102 is configured to have a relatively wider lateral width as compared to the narrow lateral width of inner root portion 101 as suggested in FIGS. 4 and 10. Outer distal portion 102 of each fabric-support branch 31-34 is coupled to canopy 28 at an outer perimeter portion 103 thereof as shown, for example, in FIGS. 3 and 10.
Each of fabric-support branches 31-34 includes outwardly presented first and second exterior edges 41, 42 as shown, for example, in FIGS. 3, 4, and 10. First exterior edge 41 extends along a first side thereof between inner root portion 101 thereof and outer distal portion 102. Second exterior edge 42 extends along an opposite second side thereof between inner root portion 101 thereof and outer distal portion 102 thereof. The outwardly presented first and second exterior edges 41, 42 are arranged to diverge from one another in a polar direction PD extending away from inner root portion 101 thereof toward outer distal portion 102 thereof as suggested in FIGS. 1-3 and 10.
Frame 30 further includes a rib mount 6 coupled to central pole 5 as shown best in FIG. 10. Each of the fabric-support branches 31-34 includes a first rib 2-1, a second rib 2-2, and a laterally extending rib spreader 10 (e.g., rib spreader 11 of FIG. 5, rib spreader 11′ of FIG. 7, rib spreader 11′′ of FIG. 8, or rib spreader 11′′′ of FIGS. 10-13). First rib 2-1 is coupled at a first end thereof to rib mount 6 and configured to include the outwardly presented first exterior edge 41 as suggested in FIGS. 3 and 10. Second rib 2-2 is coupled at a first end thereof to rib mount 6 and configured to include the outwardly presented second exterior edge 42 as also suggested in FIGS. 3 and 10. Second rib 2-2 is arranged to cooperate with first rib 2-1 to define an acute included angle 104 therebetween that is unchanged during movement of frame 30 between the collapsed and expanded positions. Laterally extending rib spreader 10 is coupled to first and second ribs 2-1 and 2-2 to locate first and second ribs 2-1 and 2-2 between rib mount 6 coupled to central pole 5 and laterally extending rib spreader 10. In illustrative embodiments, the measure of acute included angle 104 is about 20-25 degrees.
Laterally extending rib spreader 10 is configured to include an outwardly presented convex exterior edge 43 arranged to face away from central pole 5 upon movement of frame 30 to the expanded position as suggested in FIGS. 3 and 4.

Outwardly presented convex exterior edge 43 is arranged to interconnect the outwardly presented first and second exterior edges 41, 42 as suggested in FIGS. 4 and 10.
Laterally extending rib spreader 10 is coupled to free second ends of each of the first and second ribs 2-1 and 2-2 to spread the first and second ribs 2-1 and 2-2 and establish the measure of acute included angle 104 as suggested in FIGS. 4-7 and 10. Any suitable means may be used to couple laterally extending rib spreader 11 (shown in FIG. 5) or spreader 11′ (shown in FIG. 7) to first rib 2-1 and second rib 2-2.
First and second ribs 2-1 and 2-2 and the laterally extending rib spreader 10 (11′′) included in each of fabric-support branches 31′′-34′′ of frame 30′′ cooperate to form a monolithic element as suggested in FIG. 8. As suggested in FIG. 8, a rod or tube made of a plastics material, a metal material, or other suitable material is shaped using any suitable means to form a loop to provide one of the fabric-support branches 31′′-34′′.
First and second ribs 2-1 and 2-2 are arranged to lie in spaced-apart relation to one another to form an opening 36 therebetween as suggested in FIG. 4.
