1. Field of the Invention
This invention relates generally to personal heat protection devices, and more specifically to apparel article to protect a person's forearms, wrists, and elbows from work-surface heat transfer from welding.
2. Description of the Prior Art
Hazards due to burns from heat absorbed by and radiated from work materials during the welding process are well known in the welding trade. When performing welding, a standard practice is for the welder to rest one or both arms on the work material for stability. As a result of such contacts welders are likely to receive burns from heat radiated from the work-surface and through the welder's clothing adjacent to, or in contact with the work-surface. While various protective articles have been developed to protect the welder's arms, such as gloves and pads, very few are known which serve to protect the forearm, wrist and the elbow of a welder from heat and burns.
The need arises for a protective article providing protection for the forearm, wrist, and elbow of a welder, in combination with standard clothing. The article should provide for insulation for the protection of the forearm, wrist, and elbow, which may be near or in contact with a relatively hot metal structure, without substantially detracting from the comfort, mobility and typical appearance provided by more conventional articles of clothing.
Numerous methods to prevent heat transfer into the arms of welders. U.S. Pat. No. 2,388,234, issued to Abel on Nov. 6, 1945, discloses a welder's protective cape having an adjustable collar, which may be turned up for protection and straps for tightening the sleeves at the wrist for additional protection. U.S. Pat. No. 2,394,136, issued to Bakke on Feb. 5, 1946, discloses a welder's glove having a shield above the fingers. U.S. Pat. No. 3,374,487, issued to Slimovitz on Mar. 26, 1968, discloses a welder's glove with a relatively large protective cuff retained in snug engagement with the sleeve of the welder by a loop and hook fastener. U.S. Pat. No. 3,889,297, issued to Jarboe and Groseclose on Jun. 17, 1975, discloses a firefighter's glove with a relatively large protective cuff retained in snug engagement with the sleeve of the welder by a loop and hook fastener. U.S. Pat. No. 4,445,232, issued to Nelson on May 1, 1984, discloses a welder's glove having an elongated deerskin cuff. U.S. Pat. No. 4,884,297, issued to Triche on Dec. 5, 1989, discloses an arm protection, separate from any sleeve, which completely surrounds the arm and is retained in a closed position by ties. U.S. Pat. No. 5,210,878, also issued to Triche on Mar. 13, 1992, discloses a shirt having a collar, a cape, means for attaching a welding apron, removable resilient and insulating pads constructed of closed cell foam plastic inserted into pockets in the lower side of the sleeves at the forearm, and elastic bands at the forearm for retaining in position. None of the above noted patents, either singly or in combination, are seen to disclose the specific arrangement of concepts disclosed by the present invention.
Accordingly, the objectives of this invention are to provide, inter alia, a new and improved welding shirt that:
With the view of these and other objects, which will more readily appear as the nature of the invention is better understood, the invention consists in the novel combination and arrangement of parts hereinafter more fully described, illustrated and claimed with reference being made to the attached drawings.
These objectives are accomplished by a long-sleeve shirt apparel item, featuring additional permanent insulation at the points most likely to be in contact with heated materials—the ulnar side of the forearm, and the postern of the upper arm and elbow.
An exemplary embodiment of this invention is illustrated in the accompanying drawings. The drawings are illustrative only, and changes may be made in the specific construction illustrated and described within the scope of the appended claims. Other objects of the invention will become apparent from time to time throughout the specification hereinafter disclosed.
Components of the device depicted in the drawings and their corresponding reference numbers are as follows:
The present invention is a welder's shirt 10, generally depicted in
The present invention will be seen to relate to a welder's shirt 10 having a partial secondary sleeve 23 and 32, right and left respectively, permanently attached to the interior section of each sleeve, 18 and 33, right and left respectively, for use by a welder, or the like, for the protection of the forearm 37, wrist 39, and elbow 25, from radiated or conducted heat while engaged in such activities, while maintaining the mobility and appearance of a typical work shirt.
Partial secondary sleeves 23 and 32, right and left respectively, of the present invention respond to this need by providing additional thickness permanently attached from cuffs 16 and 34, right and left respectively, of each sleeve 15 and 31, right and left respectively, to a point, 24 and 35, right and left respectively, well above the midpoint 17 and 36, right and left respectively, of each sleeve 15 and 31, right and left respectively, so as to terminate above the elbow 25 of wearer 26. Partial secondary sleeves 23 and 32, right and left respectively, may comprise sheets of insulating material, which may be of the same material as the shirt or other insulating material.
Partial secondary sleeves 23 and 32, right and left respectively, are preferably formed of a resilient and flexible material of sufficient thickness to provide sufficient insulating properties, to provide comfort for the wearer of sleeve when resting his forearm upon a relatively hard surface and to permit ease of movement without restriction.
Welder's shirt 10 is constructed from front panel 11, which has a left portion 12 and right portion 13. Front panel 11 may be a two-piece front, typical of a button or snapped shirt or a one-piece front, typical of a pullover shirt. A back panel 14 is permanently attached to front panel 11 to form a typical shirt-like structure. A right principal sleeve 15 is permanently attached to the right portion 13 of front panel 11 and extends to right cuff 16. Right principal sleeve 15 has a lateral midpoint 17, which while worn is positioned generally at the wearer's elbow 25. Right principal sleeve 15 has suitable length so that right cuff 16 is generally proximate wearer's wrist 39 while wearer's elbow 25 is straight, bent or moving there between. Right principal sleeve 15 has interior 18, upper edge 19, lower edge 20, front 21, and back 22. Right partial secondary sleeve 23 is permanently attached within right principal sleeve 15 so as to provide additional thickness permanently attached from right cuff 16 of right principal sleeve 15 to a point 24 well above the midpoint 17 of right principal sleeve 15, so as to terminate above the elbow 25 of wearer 26. Right partial secondary sleeve 23, when worn, extends over a sufficient portion of the distance from upper edge 19 of right principal sleeve 15 to lower edge 20 of right principal sleeve 15 to ensure that as wearer 26 moves the additional thickness of right partial secondary sleeve 23 remains oriented over the areas that require protection.
Right partial secondary sleeve 23 has first edge 27, second edge 28, top edge 29, and bottom edge 30. Bottom edge 30 of right partial secondary sleeve 23 is attached to interior 18 of right principal sleeve 15 at right cuff 16. Top edge 29 of right partial secondary sleeve 23 is attached to interior 18 of right principal sleeve 15 at a point between midpoint 17 and front panel 11. This permanently affixes the insulating material at a point above elbow 25 when in use. First edge 27 of right partial secondary sleeve 23 is attached to interior 18 of right principal sleeve 15 between upper edge 19 of right principal sleeve 15 and lower edge 20 of right principal sleeve 15 on front 21 of right principal sleeve 15. Second edge 28 of right partial secondary sleeve 23 is attached to interior 18 of right principal sleeve 15 between upper edge 19 of right principal sleeve 15 and lower edge 20 of right principal sleeve 15 on back 22 of right principal sleeve 15. This construction creates the insulating pad extending from the wearer's wrist 39 to a point above wearer's elbow 25, and upwards on sleeve 15 to a point where sleeve 15 would not contact the work-surface in standard use. Other anticipated embodiments include a welder's shirt possessing a second sleeve, or a left sleeve only-shirt, constructed in a similar manner.
The use of a supple insulating material for partial secondary sleeves 23 and 32, right and left respectively, creates a constant thickness in the sleeve, which avoid the resulting destabilizing “ridge” between the welder's forearm 37 and the work-surface 38, as the closed cell foam plastic insulating insert disclosed in U.S. Pat. No. 5,210,878 issued to Triche. A further improvement of the instant invention over the welder's cape disclosed in '878 patent, is the wearer's elbow 25 in the instant invention is insulated from heat radiated from work-surface 38. A further improvement of the instant invention over the welder's cape disclosed in the '878 patent is the more equal distribution of the weight of partial secondary sleeves 23 and 32, right and left respectively, in 18 and 33, right and left respectively, as opposed to the unequal distribution of weight as a result of the pad disclosed in the '878 patent. A further improvement of the prior art is the permanence of secondary sleeves 23 and 32, right and left respectively, which removes the need to remove and separately store the insulating pad as disclosed in the '878 during washing. A further improvement over the '878 patent is the ability to construct shirt 10 and partial secondary sleeves 23 and 32, right and left respectively, from the same material, thus eliminating additional materials and costs, and maintaining a more cohesive appearance and performance throughout the material of shirt 10.
It is understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above. While certain novel features of this invention have been shown and described are pointed out in the annexed claims, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
