The invention relates to back rests of the characterishown in my Patent No. 1,740,791 issued December 24, 1929, and has for an object to effect improvements in the apphance 5 contributing to its efliciency' and the comfort of the user. It is a urpose to afford a combined back and head rest which will befree from ungainly appearance, and also hable in a minimum de ee to impairmentby damage to the attaching devices. A further 1mortant object is to provide a back rest 1.1151- iizing suction cup attachingdevices, in which the cups will be protected from access of foulin material, such as soapy water, hair, and ot or matter in suspension'in the bath water or afloat thereon. To this end it is an aim to enable the-incorporation of the suction cupsin such manner that they will be completely sealed from access casually while attached to a tub, yet will be of that construction reco ized as most efiicient in attaching devices 0 this kind, including the utilization of an extremely thin edge on the suction cup, freedom of the cup from contact with heavy parts of the pad while in course of application or after being a plied, and permitting the use of the most e ective materlal for construction of the cu while enabling the production of the of the rest in different materials more satisfactory for the rest, or
more economical for use therein.
It is an aim also to enable the use of the rest in alternative peculiar ways, as for a neck su port or as a head rest, according as may be esired in addition to its function as a' back rest; and further to afford a novel form of head and neck rest.
It is also an important aim to present a rest of this character which, when applied to the side of a tub will have less the appearance of an addition than an integral or normal unita element thereof.
Additional objects, advantages and features of invention reside in the construction,
arrangement and combination of parts, as
will be understood from the following description and accompanying drawing, wherein Figure 1 is a front view of a rest embody- 60 ing my invention and applied to a tub.
.Figure 2 is a lateral edge view thereof.
Figure 3 is a fra entary vertical section on the line 3-3 ofd igure 1.
' Figure 4 is a horizontal section on the line 4-4 of Figure 1.
Fi re 5 is a view similar to Figure 3 of a mo ification.
Figure 6 is a view similar to Figure 3, of a further modification.
Figure 7 shows how the 'cups 16 may be formed inte ally on the reinforcing and mounting str1p 26 corresponding to the strip 17 before described.
There is illustrated a back and head rest 10 for bath tubs 11, although the invention 55 is not limited to such application, be'it under-- stood, and may be found to have utility elsewhere and adaptable to various other uses, within' the scope of the claims. It ma be applied to'varlous styles of tubs, upon a l'of which it will tend to snugly lie against the inner face of the tub and present a neat appearance, as well as attaining the special objects and advanta es above stated.
The 'rest preferab (17 comprises an elastic bodye portion molde integrall in sponge rub r in accordance with fami iar practice in production of rubber articles of such material, and may be of such contour in plan as best'meets the requirements of the uses inso volved. As shown, it is substantially rectangular, the upper edge being preferably curved and exten ed upwardly at its central part 12 a distance. The back face 13 of the article is preferably laniform initially, although readily yielda le to distortion to conform to the curved faces of tubs, and to permit its upper edge to yield to the premure of the head, as willbe described. The dimensions of the rest in one embodiment are such that'when the article is fastened inst the inner side of a tub at one and, with its upper .part in position to receive the head an shoulders of a user seated upon the bottom of the tub the lower part will be so disposed as to'afiord support and cushion for the hips of such a person. The upper part has corners 14, between which the curved edge 12 is formed, and in the back face of the rest a short distance below the upper edge, there no are formed recesses 15 in suitable number on a horizontal line, within each of which a suction cup 16 is incorporated. In the present instance, a strip of reinforcement 17 is incorporated in the body of the pad alined with the recesses and being exposed in each ofvthe recesses 15. This reinforcement may be of various kinds, the purpose being for it to'be the supported part immediately engaged. with the suction cups, and serving to prevent the bod of the rest from becoming distorted, wea ened or worn by long continued tugging of the rest this way and that, from the normal initial position. This reinforcement may be of elastic or hard rubber strap material, or may be of metal or other stiffening material. Made in rubber quite flexible and elastic, it has been found to be highly satisfactory and effective. It may be of semirigid rubber or other material. The suction cup may be formed integrally on the reinforcement, or may be formed as a separate element having a shank portion 18 with a knobbed extremity, insertable through apertures 19 in the reinforcement 17. By this arrangement new suction cups may be quickly substituted for deteriorated ones, by simply pulling the old ones out and inserting the shanks of the new cups. The member 17 may form the back wall or extreme inner part of each recess 15, and the material of the rest immediately back of the reinforcement may be separable therefrom so as to permit the knobs of the cups to be properly inserted.
The upper part of the rest is substantially thickened to form a pillow part 20 on the front face, and extending on to the central upper portion 21 within and immediately below the curved edge 12. This thickened portion is also centrally recessed on a medial line forming a sort of groove 22in which the head or neck, or both, of the user may rest.
The recess 15 may be formed byproviding a suitable lug on the face of the mold to shape the recess, as in Figure 6, or as in Figure 3 the body of the rest may com rise a plain planiform sheet 23 of sponge ru ber of moderate thickness with circular apertures 24 entirely therethrough located in a position and relation corresponding to the recesses 15. To the face of this there is then secured the pillow section 25, which is formed with a planiform back face vulcanized to the sheet 23. The pillow section is so shaped and of just sufficient size to afford a raised part corresponding in size and shape to that 20 shown in Figures 1 and 2, when it is afiixed to the sheet 23. For this purpose a vertical section through the illow section 25 is substantially of the same s ape as one-half of a longitudinal section of a pear, inverted, its upper part rising abruptly from the sheet 23 while its lower part is tapered to a very thin edge meeting the face of the sheet 23 at a practically imperceptible angle.
In the attachment of the suction cups it may be found preferable to form them integrally on a strap 26 of elastic rubber corresponding to the form and location of the reinforcement 17 before referred to and also serving the same purpose, this stra 26 being materially thickened so that it a ords material support to the parts of the rest intervening between the suction cups. In case of the one-piece back rest and pillow, the cup strip 26 may be suspended in the mold so as to become integrally incorporated, with the sponge rubber and afford in the latter a band of dense elastic rubber which will resist tearing apart of the cells of the sponge rubber adj accnt the suction cups by unusual strains on the cups, or upon the rest when the cups are attached to a tub or the like. The cups inany of the forms indicated are so located in the recesses of the rest that the lips clear the sides of the recesses, and when the rest is adjusted in proper location within a bath tub where it is desired to attach it, the face of the rest immediately behind or over the respective recess may be pressed by the thumb or finger, the cup being thereby flattened out against the face of the tub and the air more or less completely exhausted therefrom. Relief of the manual pressure permits the cup by its inherent resilience to tend to return to normal form with greater depth and space content, thereby producing the usual vacuous condition as is well understood in such devices, and whereby the cup is held fixed upon the tub as a fastening and support. In this condition the distance from the plane of the lip of the cup at the face of the engaged tub surface to the inner face of the bottom of the recess 15 is less than the depth of the recess. Consequently, the adjacent face surfaces of the rest are pressed firmly against the face of the tub, causing the back face of the rest to lie snugly a ainst the wall of the tub and holding the e ges of the recesses 15 with especial firmness against the face of the tub excluding all water or foreign material from the cup and preserving the cup against rapid deterioration, as will be understood. The appliance will, consequently, require less 7 frequent removal for cleaning.
As in Figure 6, the cup 15 may be formed with a base or attaching flange 32 on the extremity of the shank. This flange may be cemented to the bottom of the recess or to any object requiring to be suspended by such a device.
