Abstract: The signal device, secured to the door of a rural mailbox, shows that mail has been received. The device operates by opening a shutter to display the message, "MAIL," when the mail carrier opens the mailbox door. It operates by gravity and latches magnetically. The shutter opens as a venetian blind when the weighted screen falls forward. The signal device is reset by pushing the reset tab. The device returns to the closed position by gravity. In the closed position the message, "NO MAIL," printed on the shutter, is displayed. Moving parts are contained in a weather-proof box with a transparent window. The messages, "MAIL," or "NO MAIL" are visible through the transparent window.

The cot is highly user friendly in allowing one or two ambulance attendants to easily transfer the cot into and out of the rear of an ambulance.

Abstract: A change return protection device is disclosed which prevents thieves from stuffing flexible material into the change return chutes of coin-operated machines. The device prevents stuffing of the change return chute when the change return door is opened by incorporating a blocking flap and a swinging flap around which the flexible material cannot be inserted. The device also includes a reinforcement plate which more securely joins the blocking flap to the change return door and a flat plate having V-shaped notch with sharpened edges which further prevents stuffing. Finally, the device includes an adjustable screw which restricts the size of the coin return door opening. The device is suitable for use in existing change return mechanisms.

Abstract: A reclining chair is provided with an ottoman (or leg rest) which includes primary (or main) and secondary (or mid or middle) ottoman members separately mounted to pantographic linkage subsystems of the side linkages of the chair-operating mechanism. Both ottoman members are padded and include side skirts for veiling respective portions of the side linkages when the ottoman is in a raised condition. The secondary ottoman is articulated directly to the primary ottoman, for control, so that as the ottoman is being retracted to a stowed position below the front of the seat, the secondary ottoman is rotated from a face-upwards, to a face-rearwards orientation, and received into a pocket formed behind the primary ottoman, which is rotated from a face-upwards, to a face-forwards orientation.

Abstract: The invention comprises a mail access section sufficiently dimensioned for receiving and supporting letters and packages for pickup and delivery by a mail carrier. A mail containment section supports the access section above the ground and receives the mail which is inserted through the access section. The combined length of the access section and containment section are selected so that someone cannot reach through the access section down into the mail containment section. However, the access section is appropriately dimensioned so that mail can be easily placed or tossed into the containment portion. In a alternative embodiment of the invention, a slidable table is located within the access section to provide additional storage space for outgoing packages allowing the structure to operate as a normal, non-security mailbox. In addition, a multi-user security mailbox is described that can be used for multiple residences.

Abstract: A rest pad (1,1.sup.1) for an infant is described, which is provided with a preferably padded bottom (2,2.sup.1) delimited on at least one side thereof by an essentially straight, elevated rim section (3,3.sup.1), said elevated rim section (3,3.sup.1) being formed by a filling material, which is received in a hollow reception space such that it can be removed therefrom for the purpose of lowering said rim section (3,3.sup.1). In order to be able to use such a rest pad universally and with variable sizes, it is suggested that the hollow reception space should be defined by a loop (3a to 3d, 3.sup.1 a to 3.sup. d) connected via a predetermined bending boundary (4a to 4d, 4.sup.1 a to 4.sup.1 d) to the bottom (2,2.sup.1) in such a way that, for increasing or reducing the size of the rest pad, said loop, together with the filling material, can be folded inwards towards said bottom (2,2.sup.1) and outwards away from said bottom.

Abstract: A garbage container has a housing with a rear wall, opposite side walls extending forwardly therefrom and a lid hingedly connected to the top of the rear wall and extending forwardly therefrom so as to rest on the top of the side walls in a closed position. A waste supporting platform is located within the housing and is pivotally connected adjacent its front edge to the opposite side walls for pivotal movement about a horizontal axis. A front wall extends upwardly from the front edge of the platform and has a top edge level with the top of the side walls in the closed position. A connecting member is pivotally connected to a rear portion of the platform and to a rear portion of the underside of the lid to cause upward opening movement of the lid to pivot the platform upwardly about its pivotal connection to the side walls with resultant forward pivotal movement of the front wall to facilitate access to the interior of the container.
