Abstract: An infant safety pillow of molded plastic with side walls, and a rear wall molded integrally with a gently inclined central perforated surface joined to the walls by a rolled shoulder. The base of the wall have spaced openings in their lower edges. A sponge rubber strip runs between the left and right side walls along the lower face of the front edge of the perforate surface.

Abstract: An attachment for the soles of shoes to provide a cushioned bouncing effect. The attachment has wall rising on each side of base which the user's shoe rests and securing straps attached to the sides to secure the device to user's foot. The top surface of the base is slightly ribbed to provide both a gripping and cushioning for the user's foot. The lower section of the body of the device has inflatable chambers along the sides and across the front and rear ends. Egg carton shaped recesses of generally cubic shape and with solid vertical walls are provided to provide strength and rigidity to prevent a distortion of the lower surface when the chambers are inflated.

Abstract: Improvement in an attachment for shoes in which a hollow body inflated with air and compressed in use is held on each shoe of a user, the improvement comprising constructing the attachment so that it is a bouncing attachment which provides a bounce for the user in walking, running and jumping, the attachment comprising the body having height, length and width and a nearly spherical surface, an arrangement for holding a single such hollow body positioned beneath the arch of each shoe at the point of balance thereof so that the user is able to tilt on the body about such balance point and the portion of the body in contact with the sole of each shoe covering the entire arch thereof.

Abstract: Improvement in a jumping shoe attachment having a sole plate and an arrangement for attaching the sole plate to a user's shoe, the improvement comprising an arrangement including a ground operative hinge device disposed beneath the sole plate for yieldably holding the jumping shoe attachment against the user's weight in an elevated position above the ground, the hinge device comprising a pair of hinge plates hinged about a pair of stationary hinge axes affixed to the sole plate, the hinge axes being both centered and spaced apart lengthwise in respect to the sole plate, the lower ends of the hinge plates being operative against the ground, the hinge device including a plurality of tension springs for predetermining the amount of force by which a pair of the jumping shoe attachments overcomes the user's weight, the tension springs being connected to the inside walls of the hinge plates for yieldably pulling them together during use of the jumping shoe attachment, the tension springs being preselectable as to n

Abstract: Improved bumper construction for motor vehicles comprising first and second bumper members, the second bumper member having brackets for mounting the same to the frame of a vehicle, the first bumper member slideably carried on the second bumper member, a flexible air container disposed between the bumper members, a yieldable member associated with the bumper members for yieldably urging the first bumper member inwardly in respect to the second bumper member and against the air container, the air container having an air inlet valve and air outlet valves, whereby, in the event of collision of the vehicle in which the first bumper member is forced inwardly thereof, air escapes from the air container at a controlled rate to absorb the energy of the collision.
