A device for transmitting a distress signal is provided which includes: an impact surface; a power supply for generating electrical energy resulting from an impact force applied to the impact surface; and a transmitter powered by the power supply for transmitter the distress signal. The distress signal can be an RF signal, which can be polarized. The power supply can include one or more piezoelectric generators, at least one capacitor in which the electrical energy generated by the piezoelectric generators is stored and/or an electronics component for regulating a generated voltage and for charging the capacitors. The device can also include a GPS receiver for receiving position data and providing such position data to the transmitter for inclusion into the distress signal.

A shoe includes a rear sole support for receiving a replaceable rear sole to provide longer wear. The shoe may also include a flexible plate supported by the rear sole support between the heel and the rear sole to reduce midsole compression and provide additional spring. A mounting member secures the rear sole to the rear sole support, and a locking member prevents rotation of the rear sole relative to the rear sole support during use. The replaceable rear sole and the flexible plate allow the shoe to be adapted to different desired performance characteristics depending upon the intended activity and terrain or playing surface.

A shoe includes a heel support for receiving a rotatable and replaceable rear sole to provide longer wear. The shoe may also include a graphite insert supported by the heel support between the heel and the rear sole to reduce midsole compression and provide additional spring. The replaceable rear sole and the graphite insert allow the shoe to be adapted to different desired performance characteristics depending upon the intended activity and terrain or playing surface.
摘要:
A heel member (10) for attachment to a heel stub has a ground engaging surface that matches in size and shape the heel stub surface to which it is to be attached and has a stub engaging surface 10b which is cut away (10c) in the rear curved region (10d) of the heel member so that, when attached, an open but confined space 14 is provided between the stub and a rear peripheral part of the heel member to allow flexing of said unsupported rear part. A plurality of peripherally spaced webs (10e) may be provided in the cut away region (10d) to support, and assist the return action of the rear part of the heel member during flexing.
摘要:
A shoe sole construction which features an outer sole (18) having at least one opening (26) through which a protrusion (30) of a less dense midsole (16) extends. The cutout area (26) of the more dense outsole (18) decreases the overall weight of the sole (12), while the less dense protrusion (30) aids in cushioning the foot to provide greater comfort and support. Other protrusions (32 and 68) may also be provided through other openings in the outsole to further lessen weight and increase the cushioning effect on the foot. Additionally, grooves (42) may be provided on the upper surface (40) of the midsole (16) to increase flexibility of the sole (12) and further aid in cushioning the foot and providing peripheral support were needed. The invention may be applied to athletic shoes (FIGS. 1-9), a woman's high-heeled shoe (FIGS. 10-14), or other footwear.
摘要:
An arch and heel assembly for shoes having an arch and a heel secured to each other at their upper ends. A connecting link has its front end secured to the base of the arch and its rear end secured to the base of the heel to define a substantially triangular open area between the arch, the heel and the connecting link.
