SAFETY CUSHION FOR BATHTUB

Abstract

A safety cushion that can be easily attached to and flush mounted on a surface of a bathtub and/or bathtub rim is disclosed. The safety cushion includes an elongated body fabricated from a pliable material such as rubber, silicone or polyurethane, and is provided with a plurality of substantially concave openings extending partially through a thickness of the body from a bottom surface towards a top surface. Each opening is arranged so as to leave a reduced body thickness between an apex of the opening and the top surface. This configuration enables the safety cushion to be attached to a surface of a bathtub or bathtub rim by suction when the pliable material is depressed over each opening from the top surface towards the bottom surface.

DETAILED DESCRIPTION

[0014] Specific embodiments of the disclosure will now be described in detail with reference to the accompanying figures. For simplicity and clarity of illustration, where considered appropriate, reference numerals may be repeated among the figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the examples described herein. However, it will be understood by those of ordinary skill in the art that the examples described herein may be practiced without these specific details. In other instances, well-known methods, procedures and components have not been described in detail so as not to obscure the examples described herein. Also, the description is not to be considered as limiting the scope of the examples described herein.

[0015] It will be appreciated that the examples and corresponding diagrams used herein are for illustrative purposes only. Different configurations and terminology can be used without departing from the principles expressed herein. For instance, components and modules can be added, deleted, modified, or arranged with differing connections without departing from these principles.

[0016] In the following detailed description of embodiments of the disclosure, numerous specific details are set forth in order to provide a more through understanding of the disclosure. However, it will be apparent to those skilled in the art that the disclosure may be practiced without these specific details. In other instances, well-known features have not been described in detail to avoid unnecessarily complicating the description.

[0017] Referring to FIG. 1 there is depicted an isometric view of an illustrative bathtub 100 with three safety cushions 102a, 102b, and 102c (referred to generally as 102) attached thereto over a rim 104 of the bathtub 100. The cushions 102 may bend over the rim and attach to tub surface 106 as shown. The structural details of cushions 102 are described hereinbelow.

[0018] FIGS. 2A and 2B are isometric views of an exemplary safety cushion 202 in accordance with aspects of the present disclosure. Safety cushion 202 includes an elongated body 208 fabricated, such as by injection molding, from a pliable or flexible material such as rubber, silicone or polyurethane. The body 208 includes a top surface 210 and a bottom surface 212 disposed opposite the top surface 210 to define a thickness “t” of the body 208 between the top surface 210 and bottom surface 212. The body defines a plurality of integrally or unitarily formed substantially concave openings 214 extending partially through the thickness of the body 208 from the bottom surface towards the top surface 210 and disposed proximal to each other in rows 216a, 216b and 216c extending between a first side 218 and a second side 220 of the body 208. Each substantially concave opening 214 leaves a reduced body thickness between an apex of the substantially concave opening and the top surface 210.

[0019] FIG. 3 is a side elevation view of the safety cushion 302, with the plurality of substantially concave openings 314 in body 308 shown as hidden lines. The substantially concave openings 314 extend from the bottom surface 312 towards the top surface 310, and are spaced along the length of body 308 between first side 318 and second side 320.

[0020] FIG. 4 is a sectional view along lines 4-4 in FIG. 3, showing a safety cushion 402 with details of a substantially concave opening 414 formed in body 408 of thickness “t” between top surface 410 and bottom surface 412. The substantially concave opening 414 leaves a reduced body thickness “t.sub.r” between an apex 422 of the opening 414 and the top surface 410. It will be understood by those skilled in the art, that although depicted as spherical, an alternative substantially convex opening may include non-spherical segments, such as for example, a flat apex and a conical side extending from bottom surface 412 to the apex. Any integrally or unitarily formed recess capable of providing suction may be employed within the scope of the disclosure.

[0021] FIG. 5 is a sectional view similar to FIG. 4, showing a portion of the safety cushion 502 placed on top of a tub surface 504 of tub 500 prior to attachment. As shown, the body 508 of safety cushion 502 includes the substantially concave opening 514 defined in body 508 that overlies tub surface 504. The plurality of substantially concave openings permitting attachment by suction of the body to a surface of a bathtub or bathtub rim when the pliable material is depressed over each substantially concave opening from the top surface towards the bottom surface.

[0022] FIG. 6 illustrates attachment of the safety cushion 602 to tub or rim surface 604 of the tub 600. Finger pressure “FP” is applied from the top surface 610 over the substantially convex opening (515, FIG. 5) to push the area of reduced thickness t.sub.r of body 608 to make contact against tub/rim surface 604. In this manner suction is applied in the remaining annular space 624 to attach a portion of the safety cushion 602 to tub 600. This procedure is repeated for the plurality of substantially convex openings in body 608 to attach the entire safety cushion 602 to tub 600. In order to aid in the attachment, the bottom surface 612 of body 608 may have water applied to surface 612 to assist in proper suction. To remove the safety cushion 602, the body 608 is simply peeled away from the tub/rim surface 604.
