March 3, 1953 l. B. M MONAGLE' BABY'S SAFETY PAD 1 Filed Jan. 5, 1951 mmJ M mw 0 B W A M W Patented Mar. 3, 1953 UNITED STATES PATENT OFFICE 1 Claim.
This invention relates to pad devices, and more particularly to an improved portable, inflatable safety pad for infants.
The main object of the invention is to provide an novel and improved safety pad for infants which is simple in construction, Which may be reduced to a compact size, and which is easily inflatable whenever its use is required.
A further object of the invention is to provide an improved infants safety pad which is inexpensive to manufacture. which is sturdy in construction, which is easy to inflate, and which may be employed on any flat surface or on any surface on which. it is desired to place an infant, the device serving to prevent the infant from rolling over and falling off the surface.
Further objects and advantages of the invention will become apparent from the following description and claim, and from the accompanying drawings, wherein:
Fi ure 1 is a perspective view of an improved safety pad device according to the present invention, showing an infant disposed on the pad device.
Figure 2 is a Vertical transverse cross sectional view taken through the safety pad device of Figure 1.
Fi ure 3 is an enlarged fragmentary cross sectional detail view taken longitudinally through the air intake portion of one of the air chambers of the pad device of Figure 1, showing the air fillin tube in position for admitting air into the chamber.
Figure 4 is a cross sectional view similar to Figure 3 but showing the air filling tube partially extracted from the filling Opening of the air cha ber.
Referring to the drawings, the pad device is designated enerally at I! and com rises a sheet of smooth flexible material. I2 rovided at its respective side portions with the inflatable air chambers l3, I3, such inflatable chambers defining between them a space I 4 on the sheet on which an infant may be positioned. whereby the infant will be protected against rolling off of the device by the elevated chambers I3. I3. As shown in Figure 2, the she t I may comprise two plies of thin, smooth. flexible plastic material, indicated at I5 a d I6 se red to ether a their intermediate portions to define the space I 4 and secured together around their marginal portions to define the inflatable chambers I3. I3. The plies i5 and I6 are separated at the intermediate portions of the forward ends of the chambers I3, I3 sufiiciently to define inlet passages to the chambers, as shown at IT, I1, and each inlet passa e is provided with an inwardl extending colla sible, flexible plastic tube I8 which s normallv collapsed and which may be expanded by the insertion of a suitable obiect, such as the rigid filling tube I 9, shown in Fi ures 3 and 4. Normally. the device is in a deflated condition and is folded up to a small size, whereby it may be readily carried in a pocket or in a hand bag. When it is desired to use the safety pad device, it is unfolded and first a rigid tube I 9 is inserted in the valve tube I8 of one chamber, in the manner shown in Figure 3, and air is blown into the chamber until the chamber is fully inflated, at which time the tube I9 is extracted, in the manner shown in Figure 4, whereby the collapsible tube I8 closes and seals the chamber. The same procedure is then repeated with the other chamber. As a result both of the chambers I3, I3 are inflated, whereby the device may be laid on the surface on which it is desired to place the infant, and the infant may then be placed in the space M where it is protected against rolling over and falling off the surface by the abutments provided by the inflated air chambers I3. I3.
This device is especially useful for use on automobile seats, seats of railway cars, tables, and the like, or at any surface Where it is desired to place an infant and to be assured that the infant will not roll off the surface.
While a specific embodiment of an improved infants safety pad has been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of the appended claim.
Having described the invention, what is claimed is:
An infant pad of the character described comprising two identical rectangular sheets of flexible material joined together in face-to-face relationship over their entire longitudinal intermediate portions, said longitudinal intermediate portions being of substantial width, and being joined together at substantially the entire length of their outer marginal portions, said outer marginal portions also being of substantial widths, whereby said sheets define a pair of spaced parallel, elongated, substantially straight inflatable cushion elements connected by a flexible surface therebetween which is conformable to an underlying supporting surface, the sheets being locally longitudinally separated at the ends of the respective cushion elements to define air passages, and respective inwardly projecting collapsible tubes secured in the air passages and defining valves for the respective cushion elements.
