Background of the Invention
Prior to the present invention, young mothers transporting themselves and their small children and/or babies to the sands of the sea side beaches have been physically burdened with the laborious and exhausting task of manually lifting and carrying in their hands and arms massive quantities of miscellaneous paraphanelia. The paraphanelia includes blankets, food containers, shade producing tents and/or stands, beach chairs, beverage containers, lotion bottles, sun-shielding umbrellas, baby-carriers, other miscellaneous items, and often small children and/or babies. The entire task is repeated when leaving the beach, each of the arrival and the departure requiring repeated trips between the automobile or van and the beach or alternately the involvement of several people sharing in the strenuous task. Moreover, usually the car (automobile), apart from the adult and children occupants, is totally filled and overflowing with kids, leaving no room for space-taking carts or wagons or the like.
The Objects
The present objects are directed to the overcoming and avoiding of the problems and difficulties of the foregoing types normally an integral part of the so-called joy of going to the beach.
More particularly, an object of the invention is to obtain a kit that is adapted to be intermittently assembled into a light-weight sled.
Another object is to obtain such a kit that can be assembled and disassembled by a person having little mechanical skills or abilities.
Another object is to obtain a kit above-noted that may be compactly and/or flatly transported in an automobile devoid of occupying excessive volumes of space within a car (automobile) or like.
Another object is to obtain such kit that when assembled may optionally include a shade producing canopy or umbrella-structure.
Another object is to obtain such a kit above-noted of which the assembled sled has permanently rigidly non-retractable wheels affording sled use equally well across sand and hard-surface such as concrete or the like.
Another object is for such a kit when assembled to provide an open-top container having upright sides that prevent paraphanelia from tumbling or otherwise falling from the sled.
Another object is to obtain a kit which when assembled may serve an alternate purpose of craddling a small child or baby, and/or providing a shading structure or playpen.
Another object is to obtain such a kit which when assembled includes a curtain of soft and/or flexible material or fabric adapted for folding and or wrapping around the mounting structure during transporting and/or storage thereof.
Another object is to obtain such a kit which when assembled has sufficiently large dimensions as to provide ample room for concurrent transport of massive quantities of paraphanelia.
Another object is to obtain such a kit which when assembled does not require switching from wheels to sled runners only, nor from sled-runners to wheels-only, thereby to obviate extra parts and the necessity of a person having to shift from one to the other when going from hard-surface to sand, or from sand to hard-surface, and to obviate need for mechanical skill and/or to unload or manipulate by avoiding need for shifting back and forth from sled-runners only to wheels only, or visa-versa.
Other objects become apparent from the proceeding and following disclosure.
Broad Invention
Broadly the invention may be described as a beach sled assembly kit. The kit in its broadest context includes several basic elements as a combination of interrelated elements, broadly identified as a first pair of spaced-apart runners, a second pair of forward and rearward rigid connectors, a third pair of uprightly-mountable rails, and a container structure and mechanism thereof.
More particularly, the first pair of spaced-apart sled runners each are of tubular construction and each have at least a forward end upwardly turned arcuate shape, and each of the first pair has a rearward end. The tubular construction forms tubular space.
The second pair of forward and rearward rigid connectors have the forward connectors rigidly secured in a non-shiftable state to and inter-connecting the forward ends of the first pair, and the rearward connector rigidly secured to and inter-connecting the rearward ends of the first pair.
The third pair of uprightly-mountable rails, each have upper and lower portions. Each of the forward and rearward ends of the first spaced apart-pair at their respective forward and rearward ends, includes ends-mounting structure and mechanism thereof for intermittently mounting the third pair in upright positions on said the first pair of spaced apart sled runners;
The container structure and mechanism thereof has a support surface and open space thereabove, located and positioned to support--as a conveyance--one or more of article(s) and/or person(s). The container structure and mechanism thereof are mounted on each of and extending between the upper portions of the uprightly mountable rails.
As a first preferred embodiment as an improvement on the above-described broad invention, the second pair of forward and rearward rigid connectors are forward and rearward axles each having spaced-apart revolvavble wheels rigidly mounted in a fixed state on the spaced apart wheel-mounting opposite ends. The spaced apart opposite ends are positioned, and the wheels each have an outer wheel-surface circumference sufficiently large such that the outer wheel-surface circumference of the wheel extends to a level below the first pair allowing the wheels to be rolled across a hardened surface.
In a second preferred embodiment as an improvement on the above-described first preferred embodiment, there is included a shade-providing structure and mechanism thereof, for shading the above-noted open space above the support surface. The shading-structure mounting structure and mechanism thereof also provides for intermittently detachably mounting the shading structure and its mechanized portions, onto one or more of the third pair of uprightly mountable rails and of the first pair of the spaced apart sled runners.
In a third preferred embodiment as an improvement on the above-described second embodiment, the container structure and mechanism thereof include flexible material having opposite ends mounted on and between said upper portions. The flexible material has a central support portion suspended below and between the upper and lower portions when the third pair is mounted on the first pair.
