This invention provides a holder for a sandwich that covers and protects the sandwich, and that allows an end of the sandwich to be exposed to the user while gripping the shell/housing. The holder includes an advancing mechanism that allows the sandwich end to be variably directed through an open end of the holder's shell/housing so that a portion to be eaten is exposed exclusively, while the remainder of the sandwich remains covered and isolated from the user's hands. In an illustrative embodiment, the holder and advancing mechanism is particularly suited to a small child's hands and associated motor skills. A flexible strip can extend from an actuation mechanism, such as a roller spool with an external knob assembly, around a plurality of guides to form a sling around a sandwich-holding base. Rotating the knob in an advance direction cause the strip to be drawn in, thereby raising the base.

A combination clip and hook (clip) for use generally in suspending articles, which is rotatably movable about a rotary joint between a first position in which two opposing, rotatably joined portions of the overall clip structure are oriented together to form a continuous, enclosed shape that can be secured around another, and a second position in which the two portions of the structure are rotated out of the enclosed shape, and into, for example, a S shaped hook where one portion of the structure supports the item and the other portion can be applied to another supporting member. The joint between the two portions can define a spring-loaded rotating pivot assembly with at least two indexing positions opposed by 180 degrees. The rotary joint can be constructed with a pair of confronting male and female wedge and detent inserts that are biased toward each other by an embedded spring assembly.

This invention provides a combination clip and hook (clip) for use generally in suspending articles having shoulder or hand straps, or carrying other accessories, such as keys, which is rotatably movable about a rotary joint between a first position in which two opposing, rotatably joined portions of the overall clip structure are oriented together to form a continuous, enclosed shape that can be secured around another strap or loop on an item or piece of clothing, and a second position in which the two portions of the structure are rotated out of the enclosed shape, and into, for example, a substantially S-shaped hook in which one portion of the structure supports the strap of the item and the other portion can be applied to a clothing hook, chair back, table surface, door top, or other supporting member. The joint between the two portions can define a spring-loaded rotating pivot assembly with at least two indexing positions that are opposed by 180 degrees thereby defining the enclosed orientation and hook orientation, respectively. The rotary joint can be constructed with a pair of confronting male and female wedge and detent inserts that are normally biased toward each other by an embedded spring assembly. The spring assembly can comprise a series of Belleville washers arranged in a stack about a pivot shaft.

A face mask for covering the nose and mouth of the wearer for supplying breathing gas thereto and a pair of strapless goggles which are easily and quickly donnable. The goggles are detachably attachable to the face mask by a tongue-and-groove connection wherein the tongue of the goggles is snapped into the face mask groove. Buttons are provided at the groove entrance for locking the tongue in the groove, the goggles being removable by depressing the buttons and sliding the tongue out over the depressed buttons. A face mask strap is coupled with hooks on the goggles frame for holding the goggles sealingly against the wearer's face. A vent is provided for supplying breathing gas to the goggles for venting thereof so as to prevent the entrance of smoke or disabling gases and to defog the lens.
