Firefighter's coat providing freedom of arm movement

Abstract

A firefighter's coat which has a body section and a pair of sleeve sections. Each of the sleeve sections when attached to the body section has an upper portion provided with a given length dimension and a lower portion provided with a length dimension greater than the given length dimension of the upper portion of the sleeve section. Therefore, the arms of the firefighter who wears the firefighter's coat can be freely moved as the sleeve sections are moved without appreciable strain between the sleeve sections and the body section and without significant responsive movement of the body section of the firefighter's coat. Therefore, stress upon the firefighter as a result of arm movement is minimal.

Description

BACKGROUND OF THE INVENTION

As a firefighter is engaged in firefighting activity the arms of the firefighter are actively moved.

When a firefighter is wearing a conventional firefighter's coat, upward movement of the firefighter's arms results in strain or tension between the sleeve portions of the firefighter's coat and the body portions of the firefighter's coat. Such strain between the sleeve portions of the firefighter's coat and the body portions of the firefighter's coat usually causes upward movement of the body portions of the firefighter's coat with upward movement of the sleeve portions of the firefighter's coat. Such upward movement of the body portions of the firefighter's coat causes the firefighter to expend energy in excess of the energy required to raise the sleeve portions of the firefighter's coat with upward movement of the arms of the firefighter. Of course, in view of the fact that a firefighter's coat has significant weight, the energy required to raise the body portions of the firefighter's coat adds unnecessary stress to the firefighter. Also, raising the body portions of the firefighter's coat may expose unprotected portions of the torso regions of the firefighter.

Therefore, the structure of a conventional coat of a firefighter has objectionable features.

It is an object of this invention to provide a firefighter's coat having structural features which permit arm movement of the firefighter without causing significant responsive or resulting movement of body portions of the firefighter's coat. Therefore, the firefighter's arms can move without creating unnecessary stress upon the firefighter and without causing exposure of unprotected regions of the firefighter's body.

It is another object of this invention to provide such a firefighter's coat without significantly increasing the amount of material which is normally found in a firefighter's coat.

Other objects and advantages of this invention reside in the construction of parts, the combination thereof, the method of construction and the method of use, as will become more apparent from the following description.

U.S. Pat. Nos. 4,864,655 and 5,010,591 disclose firefighters' coats which reduce resistance to arm movements. However, the structural features thereof are different from the structural features of the firefighter's coat of this invention.

SUMMARY OF THE INVENTION

This invention comprises a firefighter's coat which includes firefighting protective material, such as abrasion resistant material, flame resistant material, thermal barrier material, and moisture barrier material. These materials may be in the form of one layer or a plurality of layers.

The firefighter's coat of this invention includes a body section and a pair of sleeve sections. Each of the sleeve sections has an upper part having a given length dimension and a lower part having a length dimension greater than the given length dimension of the upper part. As the firefighter's arms are raised upwardly, the sleeve sections are raised upwardly. However, due to the fact that the lower part of the sleeve sections has a greater length dimension than the length dimension of the upper part of the sleeve sections, no appreciable strain or tension occurs between the sleeve sections and the body sections. Therefore, the body section of the firefighter's coat is not raised significantly as the firefighter's arms are raised.

Therefore, the firefighter is not required to exert unnecessary energy which would occur if the body section of the firefighter's coat should be lifted with lifting of the firefighter's arms and the sleeve sections of the firefighter's coat. Therefore, the firefighter's arms can be moved freely and independently of the body section of the firefighter's coat. Thus, any stress upon the firefighter as a result of arm movement of the firefighter is primarily limited to the arm and sleeve movement of the firefighter.

DETAILED DESCRIPTION OF THE INVENTION

FIGS. 1, 2, and 3 show a conventional firefighter's coat 18. The firefighter's coat 18 of FIGS. 1, 2, and 3 has a body section 20 and sleeve sections 22. FIG. 7 shows a layout type of view of one of the sleeve sections 22 of the conventional firefighter's coat 18. FIG. 7 shows that the sleeve section 22 has an edge portion 22e and an edge portion 22f. FIG. 7 shows a line 22a at the central region of the sleeve section 22. FIG. 7 also shows an end part 22g of the sleeve section 22. The sleeve section 22 is attached to the body section 20 as the sleeve section 22 's formed into a tubular configuration and as the edge portions 22e and 22f are attached together, and as the end part 22g is attached to the body section 20.

The sleeve section 22 is attached to the body section 20 with the portion represented by the line 22a at the upper part of the sleeve section 22 and with the edge portions 22e and 22f attached together at the lower part of the sleeve 22. Therefore, each of the sleeve sections 22 has an upper part having a length dimension equal to the length of the line 22a and a lower part having a length dimension equal to the length of the edge portions 22e and 22f. Therefore, the length dimension of the upper part of the sleeve 22 is greater than the length dimension of the lower part of the sleeve 22.

FIG. 2 shows the firefighter's coat 18 being worn by a firefighter who also wears firefighter's trousers 28. FIG. 2 illustrates conditions during a period of time in which the firefighter's arms are raised above the firefighter's head. When this upward arm movement occurs, as illustrated in FIG. 2, a strain occurs in the firefighter's coat 18 in regions R. As illustrated, the regions R are in the lower part of the sleeve sections 22 and in the body section 20 adjacent the lower part of the sleeve sections 22. When this strain occurs there is tension in the regions R, and the body section 20 is raised, as illustrated by an arrow in FIG. 2. When the body section 20 is raised, there is relative movement between the firefighter's coat 18 and the firefighter's trousers 28, as illustrated by spaced-apart lines 36 in FIG. 2.

Furthermore, when a firefighter who wears the conventional firefighter's coat 18 bends forwardly while the firefighter's arms are raised, as illustrated in FIG. 3, the rear part of the body section 20 of the firefighter's coat 18 is raised and moved upwardly with respect to the firefighter's trousers 28. Thus, a space may occur between the conventional firefighter's coat 18 and the firefighter's trousers 28, as illustrated by spaced-apart lines 38 in FIG. 3. Such a space may expose an unprotected portion of the firefighter's body.

Therefore, the structure of the conventional firefighter's coat is objectionable.

This Invention

A firefighter's coat 46 of this invention is shown in FIGS. 4, 5, and 6. The firefighter's coat 46 includes a body section 50 and sleeve sections 52 and 54. FIG. 8 is a layout type of view of the sleeve section 52. A line 52a shown in FIG. 8 represents the center part of the sleeve section 52. The line 52a also represents the length dimension of the upper portion of the sleeve section 52. The sleeve section 52 has opposed edge parts 52e and 52f, as shown in FIG. 8. The sleeve section 52 also has an end part 52g. FIG. 8 also includes a curved line 22G which represents the end part of the sleeve section 22 of the conventional firefighter's coat 18, which is shown in FIG. 7. Thus, the difference in configuration between the sleeve section 22 of a conventional firefighter's coat and the sleeve section 52 of the firefighter's coat of this invention is illustrated in FIG. 8.

FIG. 8 shows that the length dimension of the edge parts 52e and 52f is greater than the length dimension of the central portion represented by the center line 52a. As illustrated in FIG. 10, with the sleeve section 52 in tubular formation, the end part 52g of the sleeve section 52 is attached to the body section 50 with the center line 52a at the upper part of the sleeve section 52 and with the edge parts 52e and 52f attached together and positioned at the lower part of the sleeve section 52. Therefore, the length dimension of the upper part of the sleeve section 52 is less than the length dimension of the lower part of the sleeve section 52.

The length dimension represented by the line 52a in the sleeve section 52 in layout formation illustrated in FIG. 8 is preferably, but not necessarily, about one to three inches shorter than the length dimension of the edge parts 52e and 52f of the sleeve section 52 in layout formation. When the sleeve section 52 is tubular and attached to the body section 50, the length dimension 52a, at the upper part of the sleeve section 52 is about one-half to two inches shorter than the length dimension of the edge parts 52e and 52f which are attached together and positioned at the lower part of the sleeve section 52.

FIG. 9 is a layout type of view showing back panels 60 and 62 of the body section 50 of the firefighter's coat 46. FIG. 9 also shows front panels 70 and 72 of the body section 50. The back panels 60 and 62 may be attached together along edges 60e and 62f, respectively, or the back panels 60 and 62 may comprise a single integral element. FIG. 9 also illustrates in phantom, the manner by which the front panel 70 is attached to the back panel 60 and the manner by which the front panel 72 is attached to the back panel 62. However, if desired, the front panels 70 and 72 and the back panels 60 and 62 may be a single integral piece of material or materials.

FIG. 9 also illustrates the manner by which the sleeve sections 52 and 54 are attached to the panels 60, 62, 70, and 72. A line 80 illustrates attachment of the edge part 52e of the sleeve section 52 to the back panel 60 and to the front panel 70. A line 82 illustrates attachment of the edge part 52f of the sleeve section 52 to the front panel 70. Between the edge parts 52e and 52f the end part 52g is attached to the front panel 70 and to the back panel 60 along the length of the end part 52g. A similar condition of attachment exists between the sleeve section 54 and the front panel 72 and the back panel 62.

FIG. 10 also illustrates the manner by which the sleeve sections 52 and 54 are attached to the back panels 60 and 62 and to the front panels 70 and 72.

FIGS. 5 and 6 show the firefighter's coat 46 and firefighter's trousers 90 which are worn by a firefighter. FIG. 5 illustrates the firefighter with arms and sleeve sections 52 and 54 raised above the body section 50 of the firefighter's coat 46. Due to the fact that the lower part of the sleeve sections 52 and 54 have length dimensions greater than the length dimension of the upper part of the sleeve sections 52 and 54, as the sleeve sections 52 and 54 are raised separately no appreciable strain or tension occurs between the sleeve sections 52 and 54 and the body section 50. Therefore, the body section 50 of the firefighter's coat 46 may be raised only slightly with raising of the sleeve sections 52 and 54. As illustrated by line 92 in FIG. 5, there may be no relative movement or only slight movement between the firefighter's coat 46 and the firefighter's trousers 90 as the sleeve sections 52 and 54 are raised upwardly.

FIG. 6 illustrates the firefighter bending forwardly with arms and sleeve sections 52 and 54 raised upwardly. As illustrated by a line 94 in FIG. 6, in this condition there may be no relative movement between the firefighter's coat 46 and the firefighter's trousers 90. This is due to the fact that the lower parts of the sleeve sections 52 and 54 have a length dimension greater than the length dimension of the upper parts of the sleeve sections 52 and 54.

Thus, it is understood that a firefighter who wears the firefighter's coat 46 of this invention has freedom of arm movement and freedom of movement of the sleeve sections 52 and 54, without appreciable responsive or resulting movement of the body section 50. Therefore, the firefighter does not incur additional stress which would be created if there should be significant movement of the body section 50 with movement of the firefighter's arms and sleeve sections 52 and 54. Thus, the firefighter's arms and sleeve sections 52 and 54 can move freely without creating additional stress which would result if the body section 50 should move significantly with movement of the sleeve sections 52 and 54.

Thus, it is understood that the structure of the firefighter's coat 46 of this invention is superior to the structure of the conventional firefighter's coat 18.

Although the preferred embodiment of the firefighter's coat of this invention has been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts, the combination thereof, the method of construction and the manner of use, which generally stated consist in a firefighter's coat within the scope of the appended claims.
