Description
Background of the Invention
A firefighter's gloves must protect the firefighter against the hostile environment within which the firefighter works during the fighting of a fire. A firefighter's gloves must have abrasion and flame resistance, moisture resistance, and thermal resistance.
A problem has long existed in construction of a firefighter's glove. The glove must be waterproof. Therefore, a layer of waterproof or moisture barrier material must be a part of the glove. Customarily, the layer of waterproof or moisture barrier material is positioned as an insert within a glove shell which is abrasion and flame resistant. Within the insert of waterproof material is an insert of thermal barrier material. In many gloves of firefighters, in order to maintain the layer or insert of waterproof material without attachment holes, the layer of waterproof material has not been attached to any other layer within the firefighter's glove. A major problem exists in such an arrangement. When a firefighter's sweaty hand is withdrawn from the glove, one or both of the inserts or layers is usually withdrawn from the outer shell. When the firefighter attempted to again don the glove, it was necessary to spend time reworking the inserts or layers back into the glove. Of course this type of situation is objectionable.
Stitching means and methods are considered best in attaching together layers in a firefighter's glove. Attempts have been made to attach the inserts or inner layers to the outer shell by stitching means. Stitching has been employed to attach a moisture barrier layer or insert to an outer shell of a glove. However, in the past, known stitching means has created holes within the moisture barrier layer. Holes permit water to enter the moisture barrier layer. Therefore, with such problems considered, stitching has not been a suitable method of attaching a moisture barrier layer to the outer shell.
Some firefighters' gloves have had the moisture barrier insert or layer adhesively attached to the outer shell. However, in firefighting conditions, such adhesive attachment has been short-lived and has not been effective.
Another attempt to provide a waterproof firefighter's glove has resulted in a glove in which the moisture resistant insert was provided with a nipple on the end of each finger of the insert. The nipple was stitched to the outer shell, with the inner liner or thermal insert glued to the moisture resistant insert. However, such attachment means was short-lived, and the problem was not solved.
In another attempt to solve the problem, the waterproof or moisture barrier insert or layer was turned inside-out and a nipple thereon wa stitched to the inner thermal layer, with the thermal barrier layer within the moisture barrier layer. Then the moisture barrier insert or layer was glued to the outer shell. However, this structure has not been effective, and the problem not solved.
U.S. Pat. No. 4,679,257 shows a glove structure in which a tab of plastics material extends outwardly from an opening within a moisture barrier layer. A thermal barrier layer is within the moisture barrier layer. A part of the tab which is within the moisture barrier insert is attached to a thermal barrier layer. The tab extends outwardly from the moisture barrier insert and is attached to the outer shell. The moisture barrier layer is sealed at the opening therein, so that the opening is closed, and the tab is sealingly attached to the moisture barrier layer. Thus, the tab attaches together the inner layer, the moisture barrier layer and the outer shell. However, leakage problems and other problems have existed in this structure.
It is an object of this invention to provide a firefighter's glove which is waterproof.
It is another object of this invention to provide such a firefighter's waterproof glove in which there is a moisture barrier layer and a thermal barrier layer within a flame resistant shell and in which the layers and the shell are secured together without permitting entrance of water into the moisture barrier layer.
It is another object of this invention to provide a firefighter's glove in which stitching is employed in attaching a moisture barrier layer to an outer shell of the glove. Thus, the preferred method of attachment (stitching) is employed while maintaining a waterproof glove.
It is another object of this invention to provide such a firefighter's waterproof glove which can be produced at relatively low costs and which is long-lived.
Other objects and advantages of this invention reside in the construction of parts, the combination thereof, the method of production and the mode of use as will become more apparent from the following description.
Summary of the Invention
This invention comprises a firefighter's glove which includes an outer shell or layer, which is flame resistant and abrasion resistant, an intermediate layer which is a moisture barrier, and an inner layer which is a thermal barrier. Each layer is in the form of a glove, with a body part and finger parts. The glove is constructed to be waterproof, even though the layers are attached together. Connection means connect the moisture barrier intermediate layer to the outer shell, and attachment means attach the thermal barrier inner layer to the moisture barrier intermediate layer. Thus, the moisture barrier intermediate layer and the inner layer are secure within the outer shell. In this construction, each finger part of the moisture barrier intermediate layer is stitched to a respective finger part of the thermal barrier inner layer. A strip or piece of waterproof material is adhesively attached to the outer surface of each finger part of the moisture barrier intermediate layer. The strip covers the stitches and thus seals the moisture barrier intermediate layer against entrance of water into the moisture barrier intermediate layer. Each strip has an extension portion which is attached to the inner surface of a respective finger part of the outer shell of the glove. Therefore, the moisture barrier intermediate layer is protected against entrance of water while being secured to the outer layer, and the thermal barrier inner layer is attached to the moisture barrier intermediate layer. Thus, while the glove is waterproof, the firefighter's hand can be easily donned and readily withdrawn from the glove without separation of the inner layer or intermediate layer from the outer layer.

Detailed Description of the Preferred Embodiment
FIG. 1 shows the exterior of a firefighter's glove 12 of this invention. As illustrated in FIG. 3, the firefighter's glove 12 of this invention comprises an outer shell or layer 14, which is flame resistant and abrasion resistant. The glove 12 also comprises an intermediate layer 18, which is a moisture barrier. The intermediate layer 18 may be, for example, a relatively thin impervious plastics material. The glove 12 also comprises an inner layer 20, which is a thermal barrier. Each of the layers 14, 18, and 20 is in the form of a glove and has a plurality of finger portions and a body portion.
FIG. 4 illustrates an initial step in the construction of a firefighter's glove 12 of this invention. FIG. 4 shows a part of a finger portion of the firefighter's glove 12. A finger portion of the inner layer 20 is positioned within the finger portion of the intermediate layer 18. As shown in FIG. 4, stitches 30 attach together the intermediate layer 18 and the inner layer 20. The stitches 30 extend through opposed surfaces of the intermediate layer 18 and the inner layer 20.
As shown in FIGS. 5 and 6, a strip 34 of sealing material, such as an impervious plastics material or the like is attached to opposed surfaces of the intermediate layer 18 by any suitable adhesive means, such as by an adhesive material or by heat sealing, or the like. The strip 34 is shown as being folded. The strip 34 covers opposed surfaces of the intermediate layer 18, and has an extension part 34a, shown in FIGS. 6 and 7.
In the next step in the construction of the glove 12, the outer shell 14 is turned inside-out, as shown in FIG. 6. The outer shell 14 is shown as having inside stitches 38 at the edges thereof, as the stitches 38 attach parts of the outer shell 14 together. Then, as shown in FIG. 7, the extension part 34a of the strip 34 is attached to the outer shell 14, by any suitable means, such as by stitches 40. Then, as illustrated by arrows 46 in FIG. 7, the outer shell 14 is turned back to right-side out, as the outer shell 14 encloses the intermediate layer 18 and the inner layer 20, as illustrated in FIGS. 2 and 8.
Thus, as best shown in FIG. 2, the stitches 30, which attach together the inner layer 20 and the intermediate layer 18, are sealingly covered by the strip 34. Thus, the intermediate layer 18 is maintained as a waterproof moisture barrier, without the possibility of water entering the intermediate layer 18 through the finger portions thereof. Furthermore, as best illustrated in FIGS. 2 and 7, the strip 34 is attached to the outer layer or shell 14. Thus, the layers 14, 18, and 20 are secured together by stitching, which is a preferred means and method, while maintaining the moisture barrier layer 18 as a waterproof layer. Thus, the firefighter's glove 12 is a waterproof glove.
The method of construction, shown and discussed, which attaches together the outer layer 14, the intermediate layer 18, and the inner layer 20, assures the firefighter who wears the waterproof glove 12, that removal of the glove 12 from the firefighter's hand and entrance of the firefighter's hand into the glove 12 are accomplished easily and readily, as all of the layers 14, 18, and 20 remain together at all times.
Although the preferred embodiment of the firefighter's glove of this invention has been described, it will be understood that within the purview of this invention various changes may be mad in the form, details, proportion and arrangement of parts, and the combination thereof, which generally stated consist in a structure and method within the scope of the appended claims.
