DETAILED DESCRIPTION
[0037] As best seen in FIGS. 1-7, a harness 10 is provided for retaining a pair of electrical rubber insulating workman sleeves 12 on the shoulders 14 of a worker 16. The harness 10 includes a pair of fabric shoulder portions 18 configured to extend around at least part of the shoulders 14 of the worker 16 when the worker 16 is wearing the harness 10. The harness 10 further includes a pair of fastener features, shown generally at 20, with each fastener feature 20 configured for attaching an electrical rubber insulating sleeve 12 to a corresponding one of the shoulder portions 18. The harness 10 further includes a connection portion, shown generally at 22, extending from one shoulder portion 18 to the other shoulder portion 18 to limit the motion of the shoulder portions 18 relative to each other. The harness 10 further includes at least one of: (a) a collar 24 configured to grip the neck 25 of the worker 16, as shown by the embodiments of FIGS. 5-7, or (b) a pair of fabric sleeves 26 configured to extend over at least the shoulders 14 and upper arms 28 of the worker 16, as shown by the embodiment of FIGS. 1-4, with each of the sleeves 26 configured to grip at least a portion of the corresponding upper arm 28 of the worker 16.
[0038] As best seen in FIGS. 1 and 2, each fastener feature 20 can include at least one of a button 30 or a button hole 32, and in the illustrated embodiment, the fastener feature 20 includes an array of button holes 32 in the form of a linear array 34 of button holes on the front of the sleeve and a linear array 36 of button holes on the back of the sleeve. In this regard, it is important to understand that each fastener feature 20 can be just one button hole 32 or just one button 30 even though the embodiment of FIGS. 1 and 2 shows the arrays 34 and 36 of button holes and two of the buttons 30 for each of the fastener features 20 which will be advantageous in many applications. Additionally, it is important to understand that while the illustrated embodiment shows one possible set of arrays 34 and 36 that will be advantageous in many applications, other arrays of button holes are contemplated within the scope of this disclosure and no limitation to the illustrated arrays is intended unless expressly recited in an appended claim. Although the illustrated embodiment will be advantageous in many applications because the buttons 30 are utilized to fasten many conventional electrical rubber insulating gloves that are currently commercially available, it should be understood that other suitable fasteners can be utilized for the fastener features 20, including, but not limited to, snap buttons and/or hook and loop fasteners.
[0039] As seen in FIGS. 2 and 4, the connection portion 22 can be provided as a separate component that is attached, such as by stitching, to each of the shoulder portions 18, and preferably is formed from a resilient material that allows limited movement of the shoulder portions 18 relative to each other and particularly allows limited lateral movement of the shoulder portions 18 towards and away from each other. In this regard, the connection portion 22 can be provided in the form of an elasticized band, a plurality of elasticized bands, a section of elasticized fabric material, a stretchable woven fabric material, a foam material, a webbed material, and/or other suitable resilient materials or fabrics. Further in this regard, it is preferred that the resiliency, sizing and shape of the connection portion allow for up to 7 inches of lateral movement of one shoulder portion 18 relative to the other shoulder portion 18. The resiliency of the connection portion 18 allows for a single size of the harness 10 to fit all, or nearly all sizes of workers 16, including workers 16 with odd body sizes, and further allows a wide range of motion for the arms of a worker 16 without undue binding of the harness 10 while retaining the electrical rubber insulating sleeves 12 in their desired position on the arms of the worker 16.
[0040] Alternatively, as shown in FIG. 6, the connection portion 22 can be an integral part of the fabric shoulder portions 18 (i.e., a continuation of the fabric portions 18 extending from one fabric shoulder portion 18 to the other fabric portion 18). In this regard, if the fabric of the shoulder portions 18 has some resiliency, the connection portion 22 will be resilient and can be configured to allow the same limited movement of the shoulder portions 18 relative to each other as the harness embodiment of FIGS. 1-4. On the other hand, if the fabric of the shoulder portions 18 is not resilient, the connection portion will not be resilient.
[0041] As best seen in FIG. 1, the harness 10 can also include a front-side connection portion 40 that extends from the front-side of each of the sleeve portions 18 to connect the sleeve portions 18. In this regard, the connection portion 40 can be fixed to the sleeve portions 18 using any suitable means, such as by stitching. Again, it is advantageous for the front-side connection portion 40 be formed from a resilient material to allow limited movement of the shoulder portions 18 relative to each other. In the embodiment of the harness 10 shown in FIG. 1, the front-side connection portion 40 is a separate component that is attached to the front-side of each of the sleeve portions 18.
[0042] Alternatively, as seen in FIG. 5, the front-side connection portion 40 can be an integrated extension of each of the shoulder portions 18, with the resiliency of the front-side connection portion 40 being dependent upon the resiliency of the fabric forming the shoulder portions 18.
[0043] In the embodiment of FIGS. 1-4, it is very advantageous for each of the fabric sleeves 26 to include an elastic band 42 that extends around the upper arm 28 of the worker 16 when the harness 10 is worn by the worker 16. This elastic band 42 provides the desired gripping of the corresponding upper arm 26 of the worker 16. The elastic band 42 can be provided in the form of an elasticized material that is attached to the corresponding sleeve 26, or can have any other suitable structure, such as a gathering of the fabric of the corresponding sleeve 26 adjacent the end of the sleeve 26 with the gathering including an elasticized circumferential stitch or member that allows the gathering to expand and contract resiliently in the circumferential direction around the upper arm 28.
[0044] As best seen in FIGS. 5 and 7, in the embodiment that includes a neck gripping collar 24, the collar 24 can include an adjustment feature 46 for adjusting the fit of the collar 26 around the worker's neck 25. In the illustrated embodiments of FIG. 5-7 and best seen in FIG. 7, the adjusting feature 46 includes a pair of mating hook and loop strips 50 and 52, with the collar 24 being a front opening collar 24. As best seen in FIG. 7, the hook and loop strips 50 and 52 are provided in the form of a first hook and loop strip 50 on one side 54 of the open front, and another hook and loop strip 52 on the other side 56 of the open front, with the hook and loop strips 50 and 52 facing each other so as to be connectable to each other when the open front of the collar 24 is closed as shown in FIG. 5, while also allowing for adjustment of the fit (the circumferential size) of the collar 24 around the neck 25 via the circumferential extending length of each of the hook and loop strips 50 and 52. It should be appreciated that other suitable adjustment features can be utilized within the scope of this disclosure.
[0045] As best seen in FIG. 7, a unique C-shaped connector 60 is provided for connecting one of the electrical rubber insulating sleeves 12 to the harness 10. The C-shaped connector 60 is preferably formed from a semi-resilient material, such as a suitable rubber, plastic or composite material, and includes a first fastener feature 62 for attaching the C-shaped connector 60 to a single point 64 on the harness 10, and a pair of second fastener features 66 for attaching the electrical rubber insulating sleeve 12 to the C-shaped connector 60. In the illustrated embodiment, the first fastener feature 62 is provided in the form of a button hole 62 that can receive a button 30 of the harness 10, and each of the second fastener features 66 is provided in the form of a button 66 that can be received in corresponding button holes 68 provided on the electrical rubber insulating sleeve 12. Again, it should be appreciated that the invention contemplates other fastener features 62 and 66. This C-shaped connector 60 advantageously provides a broader range of motion for the electrical rubber insulating sleeves 72 when worn by a worker 16, without transferring excessive binding loads to the harness 10 worn by the worker 16. It should also be appreciated that while the C-shaped connector 60 is shown in connection with the harness embodiment of FIG. 7, the C-shaped connector 60 can be utilized with all of the embodiments of the harness 10 disclosed herein, and further can be utilized with other types of harnesses that are currently available in the industry or may be available in the industry in the future.
[0046] The fabric utilized in making any of the embodiments of the harness 10 disclosed herein can be made out of any suitable woven fabric or material, any suitable foams, any suitable elasticized fabric materials, or any other suitable fabrics.
[0047] It should be appreciated that the harness 10 disclosed in FIGS. 1 and 4 grips a worker's 16 body at the arms, which allows a firm grip for the electrical rubber insulating sleeves 12 and provides better anchoring which restricts undesirable movements of the electrical rubber insulating sleeves 12 during use. Furthermore, it should be appreciated that the embodiments of the harness 10 disclosed herein allow for the complete load to be transferred onto the shoulders, which provides better load distribution and comfort during use. It should be further appreciated that the resilient connection portion 22 helps to ensure proper fit to the body of the worker 16, including for a variety of sizes and shapes of workers 16. It should also be appreciated that the arrays 34 and 36 of button holes 32 allow for a worker to adjust the positioning of the electrical rubber insulating sleeves 12 to best fit the worker's current needs and activities. It should also be appreciated that the elasticized sleeves 26 ensure a grip and proper fit to users with different arm sizes.
