ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field
This invention relates to heating irons. In particular, it relates to heating iron covers for ski wax irons.
2. State of the Art
A number of iron covers are known. Iron covers are used for a variety of purposes such as preventing the scorching of materials being ironed. Doyel, U.S. Pat. No. 5,987,788 provides a removable iron cover with steam passage holes made of polytetrafluroethylene (PTFE) inserted over the sole plate of a steam iron to facilitate the efficient delivery of steam from the iron to the material being ironed. It also reduces friction, and acts as a thermal barrier to prevent burning of the material. Emberson-Nash et al, U.S. Pat. No. 5,815,962 provides another attachable cover for the soleplate of a hand steam iron made of a relatively thin sheet of friction reducing PTFE material including steam passage holes which provides a low friction heat shield for hand pressing steam irons.
A number of curling iron cases have been designed for storing curling irons that are still warm. These irons cannot simply be stowed in a suitcase or kit where items may be damaged in close proximity to the heated iron. Thus the prior art contains a number of curling iron travel cases used to store a hot curling iron, such as Lykowski, U.S. Pat. No. 5,950,826 which also provides a single travel case with multiple storage compartments for the curling iron and other hair maintenance devices and materials.
Ski wax irons are used to apply various types of waxes to the bottoms of skis, snowboards, and toboggans. Different waxes are used to alter the performance characteristics of the skies to suit a particular snow conditions and protect the skis from moisture. Conventional methods of applying a wax coating to a surface use a solid bar of wax to rub the wax from the bar onto the surface. This hand rubbing typically left a non-uniform and discontinuous layer of wax on the surface, which then had to be smoothed with a piece of plastic or cork. Others used a hand-held propane torch to melt the wax to form a uniform coating on the surface. Still others applied wax to the skies by brushing or rolling melted wax onto the skies.
Ski irons were developed to not only melt the solid wax to drop onto the sliding surfaces, but to then evenly distribute the same using the sole of the hot iron in a trowel-like movement. Thus the bottom of the ski wax iron must be smooth to prevent uneven application of the wax or roughing the sliding surface; thereby reducing the ski's performance. Others use ski wax irons to melt and apply a wax laminate to the bottom of the ski, such as the wax laminate described in Fitzburgh, U.S. Pat. No. 5,534,061.
These ski wax irons typically only get up to about 200 degrees Celcius to prevent breaking down the components of various types of waxes and bases of skis. However, when turned off, they still are too hot to be placed into an equipment bag without damaging other items placed therein, such as supplies of waxes. Oftentimes, when used in the field the hot ski wax iron is placed in the snow to rapidly cool it before storage. This causes water to get into the electronics damaging the iron. The sole of these ski wax irons must also be protected during storage from marring or damage. The iron cover described below provides a protective cover for these ski wax irons to aid in ready storage while still warm.
OBJECTIVES OF THE INVENTION
The objective of the present invention is to provide a cover for the new ski wax irons used to apply waxes to the bottom of skis, although it can be used with other conventional irons.
A further objective is to provide an iron cover, which protects the bottom surface of the iron from nicks, scrapes, and marring. The bottoms of ski wax irons must be protected during storage to prevent them from accidentally being dented or marred in a manner to affect the smooth application of waxes to the bottoms of skis.
Still a further objective is to provide a cover, which partially insulates the hot iron from damaging articles placed in a bag with the cooling iron. These ski wax irons often are used quickly in the field and then have to be put in an equipment bag while still warn. Thus, there is a need for heat resistant, padded storage iron cover for ski wax irons to insure a better performance of skis. It also indirectly better protects the base of the skis.
SUMMARY OF THE INVENTION
The invention comprises an iron cover having a padded bottom covered by a flexible non-transmitting heat resistant liner shaped to fit over and cover the sole of a ski wax iron. The bottom padding is of sufficient thickness to prevent the sole of the iron from being damaged by accidental contact. Attached to the padded bottom are a plurality of side flaps also covered by a heat resistant liner. The side flaps are expandably secured together to extend sufficiently around the sides of the iron to secure the iron cover there around with draw strings or other securing means. This oversize side flap configuration allows various sized of irons to be placed and secured within the cover. Each side flap is separated and structured when folded about the iron to define side heat release vents therebetween to allow heat to escape from the cooling hot iron placed therein for storage.
The preferred embodiment uses a flannel type of material for the heat resistant finer, although other materials such as plastics, metal, and fabrics could be used which protect from abrasion, are heat resistant, and will not readily transmit heat from the cooling iron. The preferred material also will not rub off against the sole of the iron during storage. Examples of preferred materials are:
a. 16 oz. Neoprene coated fiberglass, which is particularly suited to protect from abrasion and liquids,
b. 18 oz white general purpose fiberglass, 20 oz yellow fiberglass coated for abrasion that has a 1000 degree F. melt temperature,
c. 22 oz Kevlar blend, which is abrasion and heat resistant and has a 900 degree F. melt temperature,
d. 28 oz black fiberglass, which is coated for abrasion resistance and has a 1200 degree F. melt temperature,
e. 30 oz yellow fiberglass, which is coated for abrasion resistance and has a 1000 degree F. melt temperature,
f. 32 oz orange fiberglass, which is coated for abrasion resistance and has a 1000 degree F. melt temperature,
g. 18 oz bronze silica/ceramic, which is coated for abrasion resistance and has a 3000 degree F. melt temperature,
h. 12 oz duck, which is fire, water, mildew resistant,
i. 32 oz chrome tanned leather,
j. para aramid fiber, which is abrasion, cut and temperature resistant and has high tensile strength used for protective clothing,
k. ceramic fiber, which has very high temperature resistance, and low thermal conductivity, used in kiln car seals,
l. meta aramid fiber, which is inherently flame retardant and has good temperature resistance used in protective fire proximity clothing,
m. silica fiber, which has very high temperature resistance, low thermal conductivity, and low abrasion resistance,
n. Permanent flame retardant (PFR) rayon, which has good strength and is used in fire proximity clothing.
The heat resistant liner is generally covered by another flexible material resistant to abrasion, such as nylon, to protect the liner from being cut or abraded. However, the iron cover could be made entirely of the heat resistant liner material, provided it had sufficient durability.
The preferred iron cover shape is square, with the liner made of a heat resistant material laid out in a cross-shape to form side flaps with cut out corners surrounding the bottom area, which covers the sole of the iron. A similar shaped nylon outer cover is then placed over the liner, and a layer of cotton, plastic, or other padding added therebetween to pad the bottom of the iron cover to prevent damage to the sole of the iron. The heat resistant liner is then stitched, welded, or secured to the outer cover to secure the padding in position and form open loops or holes in the ends of the side flaps. A rubberized nylon or plastic cord is then threade
