The disclosure relates to coaster assemblies and more particularly pertains to a new coaster assembly for reducing penetration of chair legs into a soft substrate such as sand, dirt, and soil.
The prior art relates to chair leg stabilizers utilized for preventing chair legs from sinking into sand. However, prior art chair leg stabilizers are circumferentially larger than the leg they are attached to. Though this shape effectively distributes the weight of the chair over large area relative to the leg, these devices interfere with the ability to stack chair utilizing these stabilizers.
An embodiment of the disclosure meets the needs presented above by generally comprising a plate that is mountable to one of a plurality of legs of a chair. The plate extends laterally from the leg in a single direction that is orientated parallel to a plane that extends through bottom ends of the plurality of legs. The plate is one of a plurality of the plates, each of which is mountable to a respective one of the plurality of the legs so that each leg is engaged with one of the plates. The plates reduce penetration of the leg into a soft substrate. The plates are sized so that inner limits of the plates are separated by a distance that permits stacking of multiple ones of the chairs, with the stacked multiple ones of the chairs having an overall height that is comparable to that obtained when stacked multiple ones of the chairs lack the plates.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
The plate 12 may be curved between opposed lateral edges 22, as shown in
The plate 12 may comprise moderately flexible material, such as semirigid elastomers, so that the slot 24 can be widened to allow insertion of the bottom end 20 the leg 14. Rebounding of the plate 12 causes the opposed lateral edges 22 to contact the leg 14, thereby frictionally coupling the plate 12 to the leg 14. The present invention also anticipates the plate 12 being planar and thus configured to be positioned substantially flatly upon the soft substrate.
The plate 12 may be a substantially cylindrically shaped, as shown in
The plate 12 is one of a plurality of the plates 12, each of which is configured to be mountable to a respective one of the plurality of legs 14 so that each leg 14 is engaged with one of the plates 12, as shown in
The present invention also may comprise a bit (not shown) that is complementary to the fastener 34 and a set of instructions (not shown) for drilling an orifice 36 in the leg 14 and for attachment of the plate 12 to the leg 14 of the chair 16.
In use, the leg 14 of the chair 16 is inserted into the slot 24 and the plate 12 is secured to the leg 14 by extending the fastener 34 through the hole 32 into the leg 14. With each leg 14 engaged to one of the plates 12 of the plurality of plates 12, the plates 12 are configured to reduce penetration of the legs 14 into the soft substrate upon which the chair 16 is positioned. The plates 12 are sized to allow multiple ones of the chairs 16 to be stacked without interference by the plates 12.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the elements is present, unless the context clearly requires that there be only one of the elements.
