FIG. 2J illustrates a front view of the shoulder spacing arrangement of FIG. 2I in accordance with one embodiment of the present invention.
Shroud material 15 typically comprises one or more relatively thin, flaccid sheets. Shroud material 15 forms a large portion of apparel 10 and is included in multiple parts of apparel 10 such as body portion 12, sleeves 14, pant legs 26, boots 60, and hood 20. The number of pieces of material 15 will depend on how apparel 10 is manufactured and assembled, as one skilled in the art will appreciate, and the present invention is not limited to any particular style, assembly or design of apparel 10. Usually, a single type of material is employed for shroud material 15, however, it is contemplated that multiple types of shroud material 15 may be used (e.g., one shroud material 15 for body portion 12 and another shroud material 15 for sleeves 14 and/or hood 20). In one embodiment, shroud material 15 comprises a breathable and selectively filtering material that prevents transmission of a targeted undesirable agent through shroud material 15. In another embodiment, shroud material 15 comprises a substantially air and/or liquid impermeable material, such as a suitable plastic or non-woven fabric. Shroud material 15 may also comprise a breathable or breathable and splash resistant material, such as a non-woven fabric. Breathable portions of material 15 may also operate as a filter for outlet of air from the environment internal to apparel 10 to the environment external to apparel 10. In addition, different materials may be added or combined to shroud material 15 to increase comfort, protection, strength, appearance or another property of apparel 10. For example, plastic materials may be combined with non-woven materials to increase protection. A commercially available material such as one of the Tyvek series as provided by DuPont of Wilmington, Del., is suitable for use in shroud material 15. A non-woven such as one of the Spunbond series as provided by Kimberly-Clark Health Care of Roswell, Ga. may also be suitable. In a specific embodiment, one of ProVent 1000, 3000, 7000, 7500 or 10,000 as provided by Kappler of Guntersville, Al., is suitable for use. Shroud material 15 may also comprise a material based on polymers and copolymers of vinyl chloride, vinylidene chloride, ethylene, acrylic acids and esters, methacrylic acids and esters, propylene amines such as polyamides and other polymerizable monomers, cotton and silk, compressed nylon, polyester, and/or spandex (which may be used to increase user comfort and fit).
FIG. 2A illustrates a vertical cross section of person 11 and apparel 10 taken through a chest region 105 of person 11 in accordance with one embodiment of the present invention. FIG. 2B illustrates a vertical cross section of person 11 and apparel 10 taken through a waist region 111 of person 11 in accordance with another embodiment of the present invention. FIG. 2C illustrates a vertical cross section of person 11 and apparel 10 taken through a thigh region 109 of the person's right leg 130 in accordance with another embodiment of the present invention.
FIG. 2B also illustrates the positioning of blower 38 and inlet filter 30. In one embodiment, blower 38 and inlet filter 30 are arranged such that fresh air provided by blower 38 flows into a channel 115. As shown in FIG. 2B, blower 38 and inlet filter 30 are arranged such that blower 38 provides air into channel 115 l. This allows cooling and fresh air inlet with minimal resistance into the interior of apparel 10. Given the relatively small cross-sectional area or volume of individual spacers 100, spacer sets 120 and 140 thus provide a large volume of space and air within body portion 12 and apparel 10. In other words, when numerous spacers 100 maintain a majority of shroud material 15 away from the torso of person 11, including the shoulders and buttocks, this allows blower 38 to provide inlet cool air into a large volume internal to apparel 10, thereby providing relatively cool inlet air to cool a large surface of person 11.
Individual spacers 100 may be arranged to increase comfort of a full body suit. For example, channels 115 a and 115 e are arranged such that the arms of person 11 may rest in their natural position as the sides of person 11 without regular interference from a spacer 100. Channels 115 a and 115 e also permit forward and back motion of each arm without physical interference from a spacer 100, which is useful during walking.
Spacers 150 a and 150 b also prevent inlet filter 30 and the blower from contacting person 11 by providing support on both lateral sides of the blower. In some cases where the blower hangs from shroud material 15 (e.g., it is velcroed onto the shroud material), spacers 150 a and 150 b maintain blower 38 from contacting person 11—and maintain the air channel 115 l (between the spacers 150, shroud material 15 and person 11) that services the blower.
FIG. 5C shows a schematic of an airflow directing spacer 150 d in relation to two waist spacers 100 l and 100 m of FIG. 2B, with shroud material 15 removed to facilitate illustration, in accordance with one embodiment of present invention. As shown in FIGS. 5C and 2B, inlet filter 30 is positioned to direct air into a channel 115 l between two spacers 100 l and 100 m. Similar to the airflow directing spacer 150 c of FIG. 5C, spacer 150 d is arranged below inlet filter 30 and prevents air provided through inlet filter 30 from moving immediately downwards. However, spacer 150 d is also larger in its width dimension and therefore redirects a greater amount of air upwards and to the lateral directions. Airflow arrows 155 approximate the resultant airflow directed by spacer 150 d. For the arrangement shown in FIG. 5C, spacers 100 l and 100 m also act to redirect air moving laterally towards each spacer, although with less effect than spacer 150 d. Airflow arrows 157 approximate the resultant airflow directed by spacers 100.
