Abstract: Foot support systems include a fluid flow control system that facilitates movement of fluid into, out of, and/or within a sole structure and/or article of footwear, e.g., to change and/or control pressure in fluid filled bladder(s). Aspects of this technology may relate to one or more of: (a) footwear structures in which such systems are incorporated; (b) valve stem based fluid flow transfer systems; (c) solenoid based fluid flow transfer systems; (d) user input button features; (e) air filter features; (f) fluid tube to fluid distributor connection features; (g) fluid distributor to footwear connection features; (h) valve position sensor features; (i) valve transmission features; (j) pressure control algorithm features; (k) electronic communication features; (l) system sealing features; and/or (m) pressure sensor mounting features.

Abstract: A rack for supporting bulky objects is capable of sliding between an inclined position of withdrawal beneath the carrier basket of a shopping trolley and a horizontal position of use at the rear of the basket. Two sloping parallel wires superposed in the same vertical plane and having a smaller spacing at the front than at the rear form lateral guides for the rack and front support struts of the bottom frame. The movable rack has a flat, U-shaped structure of resilient wires so that its front portion is capable of elastic deformation in the transverse direction. At each front corner, the rack has a hook-shaped element slidably engaged in the corresponding lateral guide. The rear end of the rack is slidably mounted on a cross-member for supporting the rack in its position of rearward extension.

Abstract: A shopping trolley is provided at the top with a horizontal carrier trolley pivotally mounted on its frame in such a manner as to permit withdrawal to a vertical position at the rear end of the trolley by means of two lateral guides. Trunnions which are carried by the sides of the pivoting basket and which define its horizontal axis of pivotal displacement are engaged within the guides. These guides are inclined in such a manner as to ensure that their lower ends are placed further forward than their upper ends so that in the vertical position of withdrawal, the pivoting basket is placed between the two lateral uprights of the handle-bar frame without projecting behind this frame. In addition, the trolley basket is closed at the rear end by a flap which is freely mounted for pivotal displacement at its top edge. Trolleys of this type can be interengaged in readiness for use when their carrier baskets are placed either in a horizontal position or in a withdrawn position.
