The boot includes a foot portion and a leg cover portion extending upwardly therefrom. The boot has an inner lining surface and an outer exposed surface. A safety shield is on the leg cover portion of the boot and is positioned so as to provide additional fire protection to a specific predetermined portion of the leg of the wearer.

9 Claims, 6 Drawing Figures PATENTED NIB 6 I974 SHEET 1 0F 3 PATENTED MIR 6 I974 SHEET 2 (IF 3- SAFETY BOOT BACKGROUND OF THE INVENTION FIGS. 1 and 2 depict one embodiment of boot 20.

In hazardous occupations, a safety boot is quite com- The boot is of the type with a foot portion 21 and an mon in order to protect the legs of the wearer from various dangerous substances including fire. This is particularly true in firefighting operations where a fireman is often required to search burning buildings for people by crawling on the floor to take advantage of low heat and less smoky conditions. In doing so, the fireman encounters hot or burning timbers which will burn through the top of a conventional fire boot. This subjects the fireman to burns and often renders the boot useless.

Consequently, it would be extremely advantageous to have extra protection'in that portion of the boot which comes in direct contact with the damage producing source.

Prior art boots are known which include additional protection in various areas to alleviate damage to the wearer under hazardous conditions. However, these are merely to protect the wearer from injury primarily produced by hard blows such as would be rendered by falling heavy objects. In the case of a firemans boot, the extra protective pads which are available are used to absorb blows from falling objects or from severe contact between the firemans foot or leg with an object such as a ladder.

SUMMARY OF THE INVENTION With the above background in mind, it is among the primary objectives of the present invention to provide a safety boot which is particularly adaptable for use in areas where exposure to fire is frequent which includes a safety pad of highly fire-resistant material to reduce the danger of burns to a specific area of the wearers leg. It is particularly useful in connection with fireman s boots where the protective shield or pad is located in the knee area of the boot so that when the fireman is crawling over burning areas the danger of fire injury to his knees is minimized.

The safety boot which is for the protection of the wearer from fire and the like includes a foot portion and a leg cover portion extending upwardly therefrom. The boot has an inner lining surface and an outer exposed surface with a safety shield on the leg cover portion thereof positioned so as to provide additional fire protection to a specific predetermined portion of the leg of the wearer.

With the above objectives, among others, in mind, reference is had to the attached drawings.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings:

FIG. 1 is a side elevation view of a safety boot of the invention;

FIG. 2 is a top sectional view thereof taken along the plane of line 22 of FIG. 1;

FIG. 3 is a side elevation view of an alternative embodiment of the safety boot of the invention;

FIG. 4 is a top sectional view thereof taken along the plane of line 44 of FIG. 3;

FIG. 5 is a side elevation view of a further alternative embodiment of the safety boot of the invention; and

FIG. 6 is a top sectional view thereof taken along the plane of line 6-6 of FIG. 5.

upward extending leg covering portion 22 which are joined at a seam 23. The boot may extend up to the hips of the wearer. A strap assembly 24 is adjacent to the top of the boot for convenience of the wearer. With strap 24 open the foot can be extended through opening 25 at the top of the boot until it is properly positioned in foot portion 21 at which time strap 24 would be closed thereby snugly affixing the boot to the wearer. The boot shown is of the type which a fireman would normally wear.

A safety shield 26 is mounted on the exterior surface of the leg covering portion 22 at a location where the knee of the wearer would approximately be. The shield is designed to provide additional protection against fire. This is particularly advantageous when the wearer is on his knees on a burning surface and the knee area would be in direct contact with the burning substance.

As shown in FIG. 2, the boot includes an inner layer 27 of well-known material such as cotton fabric or a combination of rubber and fabric material. The inner layer is covered by an outer layer 28. The outer layer may be of conventional material such as rubber. Both the inner and outer layers extend the entire length of the boot including both the leg covering and foot portions. This is a matter of preference.

Mounted on the exterior surface of the leg covering portion 22 is the safety shield of pad 26. The location for the pad is between the ankle area of the boot and the top area and is approximately where the knee of the wearer would be. Shield or pad 26 is of a highly fire resistive material such as asbestos. It is mounted to the rubber outer layer 28 in any convenient fashion such as by an adhesive bond or by any other well known method..Naturally the rubber layer and the inner layer are bonded in any convenient fashion such as by adhesive or by mere frictional contact. Safety shield 26 is of sufficient surface area to protect the knee no matter what position the wearer is in but is not too large so as to add substantially to the cost of the boot. Additionally, the size of the pad is held to a minimum to avoid detraction from the desirable features of the remainder of the boot which is constructed of the rubber outer layer and the desirable inner lining. Naturally, the foot portion 21 may include many other lining materials in addition to the two shown for the leg portion of FIG. 2 depending upon the desires of the manufacturer and the ultimate user.

It has been found that for a common sized boot approximately 30 inches in height, a leg covering portion 16 inches high and wedge sized in configuration is ac ceptable. Such a portion 22 when connected to front portion 21 would be provided with a 19 inch circumference at the bottom which extends just below seam 23 and a 25 inch circumference at the top. The shield 26 applied thereto would be approximately 9% inches wide and 10% inches high and located on portion 22 adjacent to seam 23 in the front of the boot so as to accommodate the knee of a variety of different size users.

Portion 22 is formed by coating both sides of an inner layer 27 of cotton cloth with a thin film of vulcanizable cement or adhesive and then applying an outer layer 28 of rubber thereto. The exposed surface of layer 28 is coated with the adhesive at the location where the asbestos shield 26 is positioned. The combination is then vulcanized to bond the materials together. Portion 22 is then affixed to front portion 21 by applying adhesive to the adjoining parts at seam 23 and vulcanizing the combination. Front part 21 can be formed in a similar manner as described for the leg portion 22.

FIGS. 3 and 4 show an alternative embodiment designated as boot 20a. All of the similar components of boot 20a to that of boot 20 are similarly numbered with the addition of a subscript a. Boot 20a is substantially identical with boot 20 with the major exception of the positioning of safety pad 26a. Instead of being positioned on the exterior surface of outer layer 28a, safety shield 26a is mounted between outer layer 28a and inner layer 27a. There need be no alteration in any of the materials of boot 20a from the design of boot 20 and the elements of the boot can be interconnected in the similar fashion.

FIGS. 5 and 6 show a further alternative embodiment of the boot designed as boot 2012. Similar components to that of boots and 2011 are similarly numbered with the addition of the subscript b. Once again, the boot is substantially identical to boot 20 with the major change being that the safety shield 26 is mounted to the inner exposed surface of inner layer 27b. All materials are the same as in boot 20 and they are interconnected in a similar manner.

In all of the above discussed embodiments it is a primary objective to provide a safety shield for the knee area which does not detract from the features of the remainder of the boot and does not add materially to the cost of the boot. The shield is designed to give positive protection to the wearer in the knee area when he is in a position such as crawling when the knee is in contact with extremely hot or burning surfaces.

Thus, the above discussed objectives of the invention, among others, are effectively attained.
