Title: Glove attachment system

Description:
FIELD 
     Embodiments of the present disclosure generally relate to connection devices and, more particularly, to devices for attaching gloves with articles, such as sleeves, protective suits, and/or rubber and fabric articles. 
     BACKGROUND 
     Protective suits, such as HAZMAT suits, splash suits, tactical suits for law enforcement, gas tight suits, and other encapsulating suits are used in many hazardous environments to protect wearers from chemical and/or gaseous hazards and/or nuclear particles. However, different environments may require lesser or greater requirements for gloves for use with the suits. For example, a glove having relatively low barrier protection properties and high dexterity requirements or vice-versa might be desired. Furthermore, gloves are further specified for specific applications, e.g., different chemicals, fire hazards, gripping requirements, and the like. Because no one glove can fulfill these requirements, a user needs several types of protective suits and several types of gloves for different environments, which is expensive. Past attempts at securing gloves to suits have lacked features to provide a releasable mechanism and/or a reliable, secure seal for multiple glove thicknesses and suit/sleeve thicknesses. 
     A device capable of reliably and releasably joining a variety of differently sized gloves to differently sized protective suits represents an advance in the art. 
     SUMMARY 
     Embodiments of the disclosure comprise a glove attachment system, substantially as shown in and/or described in connection with at least one of the figures, as set forth more completely in the claims. Various advantages, aspects and novel features of the present disclosure, as well as details of an illustrated embodiment(s) thereof, will be more fully understood from the following description and drawings.

     DETAILED DESCRIPTION 
     Embodiments of the disclosure comprise glove attachment systems. The glove attachment systems can be used to releasably attach gloves to, for e.g., protective suits and/or other apparel, such as sleeves. Glove attachment systems may optionally be used to attach gloves to sleeves within fume hoods, biosafety cabinets, or glove boxes for releasably attaching sleeves and gloves within the hoods, cabinets, and/or boxes. The materials that the protective suits, or the sleeves within fume hoods, biosafety cabinets, or glove boxes, are made range from very thin to very thick. Also, some gloves have gauntlets or cuffs that range from very thin to very thick. Therefore, the inventors have provided a glove attachment system capable of joining thin gloves with thin suits; thick gloves with thick suits, thin gloves with thick suits, and thick gloves with thin suits. Furthermore, the inventors have provided a glove attachment system having ribs and/or grooves. The glove attachment system having ribs and/or grooves provide an audible click when the glove is securely attached to or released from the sleeve of a suit or sleeve, providing valuable feedback to the user. The glove attachment system, according to embodiments of the disclosure, attaches the glove to a protective suit or sleeve, creating a splash tight seal. In any embodiment, the glove attachment system allows the releasable separation of the suit or sleeve to the glove, providing the benefit of re-usability, which is especially valuable for low cost disposable suits but where expensive gloves are necessary. Also, for any embodiment of the disclosure, the glove attachment system allows the releasable separation of the suit or sleeve to the glove, providing the benefit of re-usability, which is especially valuable for high cost suits but where changing inexpensive gloves is necessary. Also, different gloves for different chemical environments, having different grip properties, may be joined with a plurality of different types of suits. Any and all embodiments of the disclosure are adapted to and are capable of providing a liquid tight seal between a glove and a sleeve or suit. 
       FIG. 1  shows personal protective equipment  100 , comprising an exemplary protective suit  102  having a glove attachment system  200 , according to embodiments of the disclosure. The personal protective equipment  100  comprises a glove attachment system  200  attached to the protective suit  102  at a sleeve  228 . The glove attachment system  200  comprises a frustum of a right circular cone, i.e., a frustoconical member having the shape of a hollow cone with the narrow end, or tip, truncated, and a ring-like sealing collar, as shown below, for attaching a glove  202  and/or a boot  204  to a sleeve or a pantleg. The glove attachment system  200  can, with minor changes to the design, e.g., sizes of components, be used to attach boots to suits. The glove attachment system  200  can attach a mask to a protective suit. Furthermore, two halves of a suit can be releasably joined with a similar attachment system. For example, a suit cut in half at a waist area. Embodiments according to the disclosure comprise a frustoconical inner member having outer ribs and/or grooves and a sealing collar having inner ribs and/or grooves for mating with the outer ribs and/or grooves of the frustoconical member, as shown below. 
     The protective suit  102 , or any sleeve, comprises materials, such as laminated fabrics having barrier properties and/or the like, such as materials, protective suits, and technologies disclosed in commonly assigned U.S. Pat. Nos. 7,921,467; 8,247,077; 8,268,451; and 8,505,112; the technology of each is incorporated by reference herein. Any of these materials may be coated with, for example, a barrier layer, such as a polymeric material. The thickness in millimeters (mm) of materials of which the protective suit  102  is comprised ranges from, for example, 0.25 mm to 3.0 mm. Gloves for use with such a suit or hood may have a thickness of 0.18 mm to 3.0 mm. For example, an ALPHATEC® 58-330 glove that is approximately 0.40 mm in thickness, a MICROFLEX® glove that is approximately 0.40 mm in thickness, made and marketed by Ansell Limited, a Comfort Z51G glove made by Marigold Industrial/Comasec, which is approximately 1.4 mm in thickness, and/or many others. Thinner gloves and thinner suits may also be releasably connected by the glove attachment system  200 , without departing from embodiments of the disclosure. For example, gloves may be as thin or thinner than 0.05 mm and still be releasably joined with a suit that is as thin or thinner than 0.05 mm. The protective suit  102  may be Level A, B, C, or D personal protective equipment as is known to those in the art and/or their EU equivalents. The protective suit  102  may be EN type 1-6 protective suits. For example, some protective suits  102  are Level A-Level D chemical suits and/or EN1-6 chemical suits, which may be made of various materials. These materials comprise, for e.g., single or multi-layer laminates, non-wovens, knitted or woven fabrics, and the like. The protective suit  102  may be for splash protection and/or biological protection and/or gas permeation protection and/or for flame and heat protection. The protective suit  102  comprises, optionally, double sleeves, i.e., an inner sleeve attached, for example, via a heat sealing tape, to an inside of an outer sleeve, wherein the outer sleeve protects the inner sleeve, for e.g., if the inner sleeve comprises a different material specified for protection against a different hazard than the outer sleeve. The inner sleeve may be formed differently, i.e., a non-woven, a woven, a knitted sleeve, etc. The inner sleeve may comprise a knitted cuff, for example, at a distal end of the inner sleeve for cut protection. The glove attachment system  200  discussed below may releasably engage the inner sleeve or the cuff on the distal end of the inner sleeve. Either or both of the inner sleeve or outer sleeve may comprise a cinched, elastomeric band around an end, for additional closure and protection. 
       FIG. 2  depicts an exploded view of the glove attachment system  200  of  FIG. 1 , according to embodiments of the disclosure. As shown, the glove attachment system  200  comprises the hollow frustoconical inner member  210  and the sealing collar  290 . The hollow frustoconical inner member  210  has a plurality of concentric grooves  220   a  and a plurality of concentric ribs  230   a  disposed on an external surface  240 . The hollow frustoconical inner member  210  has diameters (D 1b ) . . . (D 2b ) that decreases from a wide side  224  to a narrow side  222 , forming a tapered hollow frustoconical inner member  210 . The sealing collar  290 , which is frustum-shaped, i.e., a tapered inner surface, has a plurality of concentric grooves  220   b  and a plurality of concentric ribs  230   b  disposed on an internal surface  260 . At least one of the plurality of concentric grooves  220   b  and the plurality of concentric ribs  230   b  disposed on the internal surface  260  of the sealing collar  290  mate with at least one of the concentric grooves  220   a  and concentric ribs  230   a  disposed on the external surface  240  of the hollow frustoconical inner member  210 . The mating of the groove and rib locks part of a sleeve of the protective suit  102  and a gauntlet or a cuff on a glove therebetween (or a boot/shoe with a distal end of a pantleg), as shown below. The sealing collar  290  comprises rails  292  disposed on an outer surface  294 . The rails  292  have a larger outer diameter than the outer surface  294 , allowing one more easily grip, engage and disengage the sealing collar  290  from the hollow frustoconical inner member  210 . The glove attachment system  200  comprises the hollow frustoconical inner member  210  and the sealing collar  290 , which mate to form a liquid tight seal. 
     An outer diameter of the hollow frustoconical inner member  210 , as measured across a wide side  224  to a narrow side  222  decreases from, for example, in any embodiment according to the disclosure, across the ribs  230  on the wide side  224  from approximately 103 mm (D 1b ) to 94 mm (D 2b )) for an outer diameter across the ribs  230  on the narrow side  222 . In other words, diameters measured across the plurality of concentric ribs  230  are progressively larger from a first end of the hollow frustoconical inner member to a second end of the hollow frustoconical  0 inner member. The grooves  220  between the ribs  230  are approximately 3-4 mm in width between adjacent ribs  230  and approximately 3 mm deep. The sealing collar  290  has an inner diameter. The inner diameter has the concentric grooves  220  and the concentric ribs  230  disposed on the internal surface  260 . The inner diameter decreases from a large side  242  to a small side  244 . For example, embodiments according to the disclosure may comprise an inner diameter, measured across the ribs  230  on the large side  242 , that is approximately 104 mm (D 1a ) and approximately 95 mm across an inner diameter (not shown) across the ribs  230  on the small side  244 . In other words, diameters measured across the plurality of concentric ribs  230  are progressively larger from a first end of the sealing collar to a second end of the sealing collar. 
     Accordingly, there is a variety of gap sizes between a rib and a groove. For example, the distance between a gap formed between a groove  220   a  of the sealing collar  290  and a rib  230   b  of the hollow frustoconical inner member  210  may be less than 1 mm. However, the distance between a gap formed between a groove  220   a  of the sealing collar  290  and a rib  230   b  of the hollow frustoconical inner member  210  may be less than 1 mm. As the sealing collar  290  is pushed in direction  236 , thinner and thinner combinations of gloves and sleeves can be releasably joined. 
       FIG. 3  shows an exploded view of a hollow frustoconical inner member  210  of a glove attachment system  200  within a glove  202 , according to embodiments of the disclosure. The hollow frustoconical inner member  210 , having the plurality of concentric grooves  220  and the plurality of concentric ribs  230 , is delivered into an opening  208  adjacent to a cuff  206  of the glove  202 . A narrow side  222 , opposite a wide side  224 , of the hollow frustoconical inner member  210  is introduced into the opening  208  first by forcing the hollow frustoconical inner member  210  in direction  214  to engage the cuff  206  of the glove  202 . In this manner, the glove  202  may be of many different sizes or widths or thicknesses and still be used with the glove attachment system  200 . 
       FIG. 4  shows an exploded view of a hollow frustoconical inner member  210  of a glove attachment system  200  disposed within a glove  202  and an unattached sleeve  228 , according to embodiments of the disclosure. The unattached sleeve  228  is truncated for ease of display. Witness lines  218  (shown as dark lines) of the concentric ribs (not shown in this view) of the hollow frustoconical inner member  210  are shown on the cuff  206  of the glove  202 . The witness lines  218  are to indicate that the hollow frustoconical inner member  210  comprises a fit within the glove  202 . The sleeve  228 , having a sleeve opening  234  of the protective suit  102 , is fitted over the glove  202  having the hollow frustoconical inner member  210  disposed therein as shown by arrow  232 . 
       FIG. 5  shows a sealing collar  290  of the glove attachment system  200  in an exploded view with the glove  202  of  FIG. 4  and a sleeve  228 , according to embodiments of the disclosure. The sealing collar  290  is depicted before it is joined with the glove  202  and the sleeve  228 . As can be seen, a wide opening  234  of the sealing collar  290  is disposed to fit over the glove  202  and the sleeve  228 . A user can grip the sealing collar  290 , for example, by the rail  292 , delivering it past the glove  202 , moving the sealing collar  290  in direction  296 . The sealing collar  290  is forced over the sleeve  228  (and the cuff  206  of the glove  202 , wherein the cuff is obscured by the sleeve  228  in this view). The sealing collar  290  becomes engaged with the hollow frustoconical inner member (not shown). The sleeve  228  becomes joined with the glove  202  after mating with the concentric ribs (not shown) of the hollow frustoconical inner member (not shown) disposed within the glove  202 , as shown more fully below. 
       FIG. 6A  shows an assembled view of the glove attachment system  200 , in which the sealing ring  290  is disposed over the sleeve and the cuff of the glove, in accordance with embodiments of the disclosure. As shown, a distal end  236  of the sleeve  228  extends from the sealing collar  290 , partially covering the cuff  206  of the glove  202 . As shown, the sleeve  228  is disposed inside the sealing collar  290 . The protective suit  102  may comprise, as stated above, an additional sleeve (not shown), disposed over the sleeve  228 , which covers the sleeve  228  and the sealing collar  290 . 
       FIG. 6B  shows an alternative assembled sectional view of the glove attachment system  200 , in which the sleeve  228  is disposed over and through the sealing collar  290 , in accordance with embodiments of the disclosure. Alternative to the attachment method as shown in  FIG. 6A , the sleeve  228  can be disposed over and subsequently through the sealing collar  290  so that the entirety of the sealing collar  290  is covered by the sleeve  228 . As shown, the hollow frustoconical inner member  210  is shown as a cross section inside a cross section of the cuff  206  of the glove  202 . The sleeve  228  of the protective suit  102  is shown as traveling around the sealing collar  290  (shown in cross section), at a fold  298  of the sleeve  228 . In this manner, the sealing collar  290  is protected from hazards, for example, chemical splashes, and the like. This method of attaching the glove  202  to the sleeve  228  obviates any need for an outer sleeve/double sleeve, as described above. 
       FIG. 7  shows a magnified view of a cross section of the assembled glove attachment system  200  of  FIG. 6A . The sealing collar  290  having the rib  230   a  compresses the sleeve  228  with the glove  202  between the rib  230   b  of the hollow frustoconical inner member  210 , leaving the hand opening  288 . Because the glove  202  and the sleeve  228  extend in opposite directions, pulling on one, i.e., creating tension, only serves to make a seal between the hollow frustoconical inner member  210  and the sealing collar  290  tighter. Moreover, by making the hollow frustoconical inner member  210  ribbed with the ribs  230   b  and the sealing collar  290  having grooves  220   a , the ribs  230  (disposed on either the hollow frustoconical inner member  210  and the sealing collar  290 ) of the glove attachment system  200  seals with at least one of the grooves  220  (disposed on either the hollow frustoconical inner member  210  and the sealing collar  290 ) and permits varying thicknesses of the sleeve  228  of the protective suit  102  and the glove  202 . Furthermore, a “click feeling and sound,” provides feedback when attaching the glove  202  to the protective suit  102  as well as a more accurate placement, i.e., reducing the risk of the sealing collar  290  from slipping down. A click may sound when detaching the glove  202  from the protective suit  102 . It is to be further understood that the height of the ribs  230  and the depth of the grooves  220  permit a range of thicknesses of suits and gloves to be safely and reliably joined. 
     A variety of sizes/thicknesses of gloves and protective suits can be accommodated by the glove attachment system  200 . Embodiments of the disclosure include a hollow frustoconical inner member  210  having, for example, an effective outer diameter of approximately 100-103 mm on a wide side and approximately 93-96 mm on a narrow side, which is measured across the ribs. Embodiments of the disclosure include a hollow frustoconical inner member  210  that is approximately 45-50 mm in length. Embodiments of the disclosure include a sealing collar  290  having an inner diameter measured across the ribs  230  that is approximately 101-104 mm across a wide side and approximately 94-96 mm across a narrow side. Embodiments of the disclosure include a sealing collar  290  that is approximately 25-30 mm in length. Each of the hollow frustoconical inner member  210  and the sealing collar  290  comprise a slant angle θ of approximately 80-84°. Accordingly, any of the grooves  220   a  of the sealing collar  290  can mate with any of the ribs  230   b  of the hollow frustoconical inner member  210  because of the differences in diameter, i.e., the hollow frustoconical inner member  210  and the sealing collar  290  can join a protective suit and glove of many differing thicknesses. In other words, a sealing collar  290  having a plurality of successively smaller diameters across the ribs  230   a , disposed on an inner diameter, provides a variety of different coordinating ribs from the hollow frustoconical inner member with the grooves of the sealing collar  290 . For example, a thick glove and/or protective suit can be joined if the diameter of a rib  230  of the hollow frustoconical inner member  210  is on the lower end of the spectrum, e.g., 94 mm while mating with a groove  220   a  of the sealing collar  290  that is on a wider end of the spectrum, e.g., 103 mm. In other words, a gap between 103 mm and 94 mm could accommodate a total thickness of a glove and a sleeve approximately 9 mm therebetween. Similarly, if the diameter across a rib  230   b  of the hollow frustoconical inner member  210  is on the higher end of the spectrum, e.g., 96 mm while mating with a groove  220   a  of the sealing collar  290  that is on a lower end of the spectrum, e.g.,  101  mm, the distance between the rib  230   b  and the groove  220   a  is 5 mm. The grooves  220   a  of the sealing collar  290  comprise a radius of approximately 1 mm. The ribs  230   b  of the hollow frustoconical inner member  210  comprise a radius of approximately 1.6 mm. Embodiments of the disclosure optionally contemplate a glove attachment system  200  in which the dimensions of the hollow frustoconical inner member  210  and the sealing collar  290  are smaller or larger so that smaller and larger articles can be releasably joined. 
     The hollow frustoconical inner member  210  and the sealing collar  290  may be made of any suitable material. For example, the hollow frustoconical inner member  210  and the sealing collar  290  may comprise steel, aluminum, various alloys, and the like. The hollow frustoconical inner member  210  and the sealing collar  290 , according to any of the embodiments of the disclosure, comprise plastics materials, which may be semi-crystalline or amorphous materials. For example, suitable plastics materials include, at least, polyethylene, such as high density polyethylene (HDPE), polypropylene (PP), nylon 6, nylon 66, polybutylene terephthalate (PBT), polyacetal, polyvinyls, acrylonitrile-butadiene-styrene (ABS), styrene-acrylonitrile (SAN), and other suitable polymeric materials and/or blends or alloys thereof. Exemplary embodiments according to the disclosure include wherein the hollow frustoconical inner member  210  comprises HDPE and the sealing collar  290  comprises PP. The hollow frustoconical inner member  210  may comprises a rigid plastics material, such as ABS and the sealing collar  290  comprises a more resilient, flexible material, for example, a natural rubber or natural rubber blend, in any embodiment. A sealing collar  290  comprising natural rubber can be quite stiff yet compliant and resilient, creating a particularly tight seal in tension with the hollow frustoconical inner member  210 . Furthermore, a sealing collar  290  made from a rubber material will comprise a high coefficient of friction, adding to the force needed to unlock the hollow frustoconical inner member  210  from the sealing collar  290 . The hollow frustoconical inner member  210  and the sealing collar  290  need not be made of the same material. 
     The hollow frustoconical inner member  210  and the sealing collar  290  may be manufactured by injection molding processes or casting processes, as are known to those in the art. The injection molding processes or casting processes can produce hollow frustoconical inner members  210  and sealing collars  290  having particularly tight tolerances, e.g., +/−0.01-0.02 mm, providing tight seals in use. 
     Embodiments of the disclosure include a method for attaching a glove to a sleeve, comprising the step of placing a ribbed hollow frustoconical inner member into a glove; placing a sleeve over the glove; and placing a sealing collar having grooves over the sleeve, wherein at least one of the ribs of the hollow frustoconical inner member mate with at least one of the grooves of the sealing collar, forming a seal that releasably joins the sleeve to the glove. 
     Embodiments of the disclosure comprise an alternative method for attaching a glove to a sleeve, comprising the steps of placing a ribbed hollow frustoconical inner member into a glove; placing a sleeve over the glove; and placing the sleeve over a sealing collar and through a center of the sealing collar, wherein at least one of the ribs of the hollow frustoconical inner member mate with at least one of the grooves of the sealing collar, forming a seal that releasably joins the sleeve to the glove. 
     All ranges recited herein include ranges therebetween, and can be inclusive or exclusive of the endpoints. Optional included ranges are from integer values therebetween (or inclusive of one original endpoint), at the order of magnitude recited or the next smaller order of magnitude. For example, if the lower range value is 0.2, optional included endpoints can be 0.3, 0.4, . . . 1.1, 1.2, and the like, as well as 1, 2, 3 and the like; if the higher range is 8, optional included endpoints can be 7, 6, and the like, as well as 7.9, 7.8, and the like. One-sided boundaries, such as 3 or more, similarly include consistent boundaries (or ranges) starting at integer values at the recited order of magnitude or one lower. For example, 3 or more includes 4 or more, or 3.1 or more. 
     The foregoing description of embodiments of the disclosure comprises a number of elements, devices, machines, components and/or assemblies that perform various functions as described. These elements, devices, machines, components and/or assemblies are exemplary implementations of means for performing their respectively described functions. 
     Although only a non-exhaustive description of exemplary embodiments of the present disclosure have been detailed above, those skilled in the art will readily appreciate that many modifications to the sizes of the ribs, grooves, slant angles, diameters, and the like are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of this disclosure.
