The present invention relates to the field of pockets for protective garments, and more specifically to pockets for safely and securely holding V-blade safety and rescue knives.
Many safety and rescue workers, as well as many members of the military, frequently carry with them heavy tools that are needed when responding to emergency and rescue situations. These tools often include knives and other cutting tools that are suitable for rescue activities such as cutting through a seat-belt in order rescue a victim of a car accident, or cutting through a pilot's harness in order to rescue a pilot from being trapped within an airplane.
While knives and axes are very useful in many situations, they are also cumbersome to carry, and include sharp blades. Traditionally, knives and other emergency rescue tools have been carried by emergency and rescue workers within the outer pockets of their protective garments. However, carrying heavy knives and cutting tools in this manner creates many problems.
When a heavy-duty knife is placed within an outer pocket of a protective garment, the knife is able to move around and shift positions. This is very uncomfortable for the wearer, as the movement of the knife within the pocket constricts and hinders the movement of the wearer, and often bangs the wearer's leg. In addition, the movement of the heavy knife can cause other tools within the pocket to become crushed or otherwise damaged. Furthermore, the movement of the knife within the outer pocket causes the knife to shift position and orientation. This makes it difficult for a wearer to access the knife quickly and easily when the wearer needs to retrieve the knife from the pocket. In addition, when the user has to fish the knife out of the pocket, the wearer must be very careful not to grab the knife by the blade. This presents a risk of injury to the user, which is undesirable when the user is faced with an emergency or rescue situation.
In light of the above, it is clear that there is a need in the industry for an improved method for enabling an emergency worker to carry heavy knives that alleviates at least in part the deficiencies of existing garments.
In accordance with a broad aspect, the present invention provides a pair of protective pants that comprise a first leg, a second leg and a pocket positioned on at least one of the first leg and the second leg. The pocket has a width and a depth and defines a bottom end and a top end. The pocket comprises an internal chamber, an opening to the internal chamber at the top end of the pocket and at least one tool-positioning wall for narrowing the width of the pocket towards the bottom end. The tool-positioning wall provides a surface against which a blade portion of a knife rests when the knife is positioned within the internal chamber of the pocket.
In accordance with another broad aspect, the present invention provides a pocket arrangement for a protective garment. The pocket arrangement comprises a first pocket that has a first width, a first depth, a front face, a first internal chamber and a first opening to the first internal chamber. The pocket arrangement further comprises a second pocket positioned on the front face of the first pocket. The second pocket has a second width and a second depth and defines a bottom end and a top end. The second pocket comprises a second internal chamber, a second opening to the second internal chamber and a tool-positioning wall for narrowing the width of the pocket towards the bottom end. The tool-positioning wall provides a surface against which a blade portion of a knife rests when the knife is positioned within the internal chamber of the pocket.
In accordance with another broad aspect, the present invention provides a pocket arrangement for a protective garment. The pocket arrangement comprises a first internal chamber and a first opening to the first internal chamber.

Shown in
The pair of protective pants 10 may be suitable for use by a firefighter, policeman, paramedic, emergency scene first-responder or military personnel among other possibilities. The pair of protective pants 10 is preferably made of a durable and tear-resistant material, such as a woven aramid fiber and/or polybenzimidazole fibers, that provide flame, abrasion and pierce resistance. The pants 10 may be adorned with knee patches 20, reflective material 22 and/or any other accessory that may be required or desirable for the intended purpose of the protective pants 10. It should be appreciated that the construction and material of the pair of protective pants 10 is not intended to be limiting to the present invention.
For the sake of simplicity, only pocket 12b will be described in more detail below. However, it should be appreciated that both pockets 12a and 12b are substantially the same, and that the description provided for pocket 12b is equally as applicable to the pocket 12a.
Shown in
The pocket 12b further comprises a tool-positioning wall 34 for narrowing the width “w” of the pocket towards the bottom end 28. While the width “w” of the pocket is between 4 and 8 inches, the width at the bottom end 28 is generally between 2 and 3 inches. As will be explained in more detail further on in the description, the tool-positioning wall 34 provides a surface against which a portion of a tool rests when positioned within the internal chamber of the pocket 12b, for preventing the tool from changing positions within the pocket 12b.
The pocket 12b comprises a flap 32 that is shown in a closed position in
The pocket 12b further comprises a first side wall 36 and a second side wall 38, that each comprises a surface length that extends between the top end 26 and the bottom end 28 of the pocket 12b. As used herein, the term “surface length” refers to the length that is measured between the top end 26 and the bottom end 28 following the edge of each side. The surface length of the first side wall 36, which faces towards the front of the protective pants, is substantially the same as the length “l” of the pocket. However, the surface length of the second side wall 38, which faces towards the back of the protective pants, is slightly longer than the length “l” of the pocket 12b, due to the angle of the tool-positioning wall 34.
The side walls 36 and 38 may be formed by seams that join the front face 24 of the pocket to the surface of the leg 16 of the pair of pants 10. Alternatively, the side walls 36 and 38 may be formed by a more three-dimensional wall, such as in the case of the pocket 12b shown in
As shown in
The asymmetric shape of the pocket 12b resulting from the angle of the tool-positioning wall 34 creates an internal chamber having an angled wall that is suitable for receiving a specific type of tool, and maintaining that tool in a desired orientation.
Shown in
The particular V-blade safety and rescue knife 50 shown in the Figures has the dual function of being able to break into the canopy of an aircraft (with the metal end of the tool) and then extricate a pilot from his/her harness using the blade portions 54 of the tool.
Shown in
As such, the internal chamber of the pocket 12b is shaped in order to snugly receive a V-shaped safety and rescue knife 50, or similarly shaped knife, so as to prevent the knife 50 from moving around and/or changing orientation within the pocket 12b. The blade portion 54 of the knife 50 is received within a narrower bottom portion of the internal chamber and the movable arm blade portion 58 is able to rest against the angled surface created by the tool-positioning wall 34.
The pocket 12b of the present invention thus allows an emergency worker to carry this important tool on his or her person. Traditionally, heavy and awkward tools, such as the V-blade safety and rescue knife 50 have been carried in a tool roll, which requires time to access. When the V-blade safety and rescue knife 50 is carried in the pocket 12b, it allows easy access to the tool and allows the emergency worker to save precious time. When the V-blade safety and rescue knife 50 is needed for emergency extrication, it takes only second to access, thus becoming potentially life-saving.
Although only one angled tool-positioning wall 34 is shown in the Figures, it should be appreciated that multiple angled tool-positioning walls 34 could be used in order to create a narrowed bottom portion of the pocket 12b. For example, a first angled tool-positioning wall 34 may extend between the second side edge 38 and the bottom end 28, and a second angled tool-positioning wall 34 may extend between the first side edge 36 and the bottom end 28. In such a scenario, the bottom portion of the pocket 12b may have the shape of a truncated symmetric V.
When the V-blade safety and rescue knife is positioned within the pocket 12b, the handle 52 of the knife 50 extends upwardly towards the opening 30 of the pocket 12b such that a wearer of the protective garment is able to easily access the handle 52 of the knife 50 without worrying about how the orientation of the knife may have changed during the course of the wearer's regular activities. This helps to prevent the wearer from accidentally grabbing the blades 56 and 58 of the knife 50.
In order to be able to place the V-blade safety and rescue within the pocket 12b, the opening 30 of the pocket 12b is wider than the bottom edge 28 of the pocket. More specifically, the opening 30 of the pocket 14 is wider than the width anywhere between the first side wall 36 and the tool-positioning wall 34. This provides easy access to the handle, even for a person having a gloved-hand.
Although walls 28, 36, 38 and 34 are all shown as being distinct walls, it should be appreciated that one continuous wall that bends in order to form a shape similar to that shown in
Shown in
In the embodiment shown, the first pocket 62 has a generally rectangular shape with a top end 66, a bottom end 68, a first side wall 70 and a second side wall 72. The first pocket 62 further comprises a front face 76, an internal chamber (not shown) and an opening 74 to the internal chamber. In general, the internal chamber is defined between the interior surface of the front face 76, the outer surface of the pant leg 16 and internal surface of the two side walls 70, 72 and the bottom end 68. However, the interior of the pocket may include a lining, such that the internal chamber will be defined by the internal dimensions of the lining. The lining may be made of a reinforcing material, such as aramid fabric, leather, coated aramid among other possible fabrics, for preventing tearing and piercing of the pocket 62.
The side walls 70, 72 and the bottom end 68 may be formed by seams that join the front face 76 of the pocket to the surface of the leg 16 of the pair of pants 10. Alternatively, the side walls 70, 72 and bottom end 68 may be formed by a more three-dimensional construction, wherein the sidewalls 70, 72 and bottom end 68 are created by pleated pieces of material that extend between the front face 76 and the surface of the leg 16 of the pair of pants.
The first pocket 62 has a first width “w1” and a first length “11”. Although the first pocket 62 is shown as having a rectangular shape, it should be appreciated that the first pocket 62 could be of a variety of other shapes, as well. The present invention is not limited to the shape of the first pocket 62.
The second pocket 64 is substantially the same as pocket 12b described above with respect to
As shown in
In accordance with the present invention, the first width “w1” of the first pocket 62 is wider than the second width “w2” of the second pocket 64. In addition, the first length “l1” of the first pocket 62 is longer than the second length “l2” of the second pocket 64.
The pocket arrangement 60 further comprises a flap 80 that is shown in a closed position in
In a further embodiment of the invention that is not shown in the Figures, the pocket arrangement 60 may be constructed differently, such that the shape of the second pocket 64 is located within the first pocket 62. In such an embodiment, the shape of the internal chamber of the second pocket 64 is included within the first pocket 62, such that from the outside, the pocket arrangement 60 appears to be a single pocket, but on the inside, the pocket arrangement 60 comprises a first internal chamber and a second internal chamber that is different from the first internal chamber, wherein the second internal chamber has the shape of the internal chamber of pocket 12b and pocket 64 as described above. More specifically, the second internal chamber comprises the tool-positioning wall 34 such that an edge of the tool is able to rest against the angled surface of the tool-positioning wall 34 for preventing the tool from moving around. Although the shape of the second internal chamber would not be visible from the outside, as described above, when the flap 80 is lifted, the pocket arrangement 60 comprises a first internal chamber that has a substantially rectangular shape, and a second internal chamber that has the asymmetric shape of the second pocket 64 as described above.
Although the present invention has been described in considerable detail with reference to certain preferred embodiments thereof, variations and refinements are possible without departing from the spirit of the invention.
Therefore, the scope of the invention should be limited only by the appended claims and their equivalents.
