- the present invention relates to a waterproof garment connector arrangement for attaching a distal garment part to a main body of a garment, to a method of attaching the distal garment part to the main body of the garment using the waterproof garment connector arrangement, and to a wet suit, immersion suit, survival suit, dry suit or semi dry suit including at least one of the connector arrangements.
- wet suits and dry suits are known. Dry suits are substantially watertight and are fairly loosely fitting to allow thermally protective clothing to be worn underneath. Wetsuits are closer fitting to the body. A limited amount of water is allowed to enter the small space between the suit and the wearer's body, whereafter further water exchange ceases. The material of the wet suit is thermally insulating. The water present between the wearer's body and the suit helps to retain body heat.
- Immersion and survival suits have a similar construction to dry suits and may be worn by pilots or seafarers when there is a likelihood of evacuation into water.
- Protective waterproof garments are also used by personnel who need to enter hazardous areas, such as where dangerous chemicals are present.
- Garments of the type described above generally comprise a main body part which covers the trunk, arms and legs of the wearer. Often, one or more of the glove parts or wrist seals, foot-receiving parts or ankle seals and a head-receiving part or neck seal of the garment will be separate. This makes it easier to don the garment and may allow the garment to be worn by persons with a greater range of body sizes.
- the embodiments of the present invention seek to provide an alternative garment connector arrangement.
- the present invention provides a waterproof garment connector arrangement for attaching a distal garment part to a main body of a garment, the connector arrangement including:
- the second part is resiliently deformable.
- the second part may have a Shore hardness of 45-75 but may fall outside of this range depending upon the type of material being used to form the annular member.
- the second outward facing recess may have an entrance having a width that is less than a width of the annular member.
- the arrangement may be such that the entrance deforms in use to allow the insertion of the annular member into the second outward facing recess, whereafter the entrance resiles to hold the annular member in the second outward facing recess and/or to provide a generally smooth outer surface.
- the second outward facing recess may have a generally partially circular transverse cross-section that corresponds in shape to the transverse cross-section of the annular member.
- the annular member may be an O-ring.
- the second part may be configured to be deformed during connection to the first part to slide over the wall of the first outward facing recess and the protrusion, whereafter the second part resiles to engage the first outward facing recess and the protrusion to hold the first and second parts together.
- the first part is resiliently deformable.
- the first part may have a Shore hardness of 45-75 but may fall outside of this range depending upon the type of material being used to form the annular member.
- the second part may have a Shore hardness that is the same as the first part, although this is not essential.
- the shore hardnesses of the first and second parts may be different from each other, and, for example, the first part may have a Shore hardness that is 15% greater than the second part.
- the wall of the first outward facing recess and the protrusion of the first part may be configured to be deformed during connection to the second part, whereafter the wall of the first outward facing recess and the protrusion resile. Such an arrangement may allow a straightforward coupling procedure of the first part to the second part.
- the first part may include an abutment formation facing the protrusion for abutting in use an end wall of the second part, the arrangement being such as to hold the second part in engagement with the protrusion. This enhances the coupling together of the first and second part.
- the first part and the second part in the embodiments are annular, and the first and second outward facing recesses extend circumferentially.
- the distal garment part may comprise a glove or wrist seal; a foot-receiving part (sock or boot) or ankle seal; or a head-receiving part (hood) or a neck seal.
- the protrusion may be inclined.
- the embodiment allows the distal garment part to be easily connected to the main body of the garment in a waterproof manner.
- the garment may be a dry suit, a semi dry suit, a wet suit, an immersion suit, a survival suit or other protective suit.
- Semi dry suits are basically wet suits that have seals in the wrists and neck. These suits allow in a limited amount of water but restrict the flushing of water in the neck and wrist by using seals in these areas.
- the annular member fits into the second outward facing recess, and the arrangement is such that the annular member urges the outer engagement member against a wall of the first outward facing recess to secure the first part to the second part and thereby eliminates ingress and egress of water between the inside and outside faces of the first part and second part (where the wall of the first outward facing recess is) when connected together.
- the annular member has an inner circumference that is less than the circumference of the second part at the base of the second outward facing recess and this exerts a compressive force around the outside of the second part, thereby locking the protrusion in place.
- This arrangement may ensure that when a tensile or pulling force is applied between the first and second parts and along the axis of the parts they are not able to separate.
- the force that might be applied is that which might be encountered in normal use of the garment or when doffing and donning the garment.
- the present invention provides a wet suit, immersion suit, survival suit, dry suit or semi dry suit including at least one connector arrangement of the type discussed above, the distal garment part comprising a glove, a wrist seal, a foot-receiving part, an ankle seal, a head-receiving part or a neck seal of the suit.

Abstract
A waterproof garment connector arrangement attaches a distal garment part (e.g. a glove) to a main body of a garment. The connector arrangement includes a first part having a first outward facing recess and an inward facing protrusion; and a second part having an outer engagement member for being received in the first outward facing recess and in inner engagement member for engaging the protrusion. The outer engagement member includes a second outward facing recess at least partially accommodated in the first outward facing recess. An annular member is fitted into the second outward facing recess, so that the annular member urges the outer engagement member against a wall of the first outward facing recess to secure the first part to the second part.
Description
- The present invention relates to a waterproof garment connector arrangement for attaching a distal garment part to a main body of a garment, to a method of attaching the distal garment part to the main body of the garment using the waterproof garment connector arrangement, and to a wet suit, immersion suit, survival suit, dry suit or semi dry suit including at least one of the connector arrangements.
- Various waterproof garments are known which are used by divers, military personnel or in emergency situations where immersion in water is likely.
- For diving, wet suits and dry suits are known. Dry suits are substantially watertight and are fairly loosely fitting to allow thermally protective clothing to be worn underneath. Wetsuits are closer fitting to the body. A limited amount of water is allowed to enter the small space between the suit and the wearer's body, whereafter further water exchange ceases. The material of the wet suit is thermally insulating. The water present between the wearer's body and the suit helps to retain body heat.
- Immersion and survival suits have a similar construction to dry suits and may be worn by pilots or seafarers when there is a likelihood of evacuation into water.
- Protective waterproof garments are also used by personnel who need to enter hazardous areas, such as where dangerous chemicals are present.
- Garments of the type described above, generally comprise a main body part which covers the trunk, arms and legs of the wearer. Often, one or more of the glove parts or wrist seals, foot-receiving parts or ankle seals and a head-receiving part or neck seal of the garment will be separate. This makes it easier to don the garment and may allow the garment to be worn by persons with a greater range of body sizes.
- It is desirable that such distal garment parts can be mounted and removed quickly and reliably, whilst providing a waterproof connection to the main body part. Examples of known garment connectors are disclosed in EP1352577 and EP0406139.
- The embodiments of the present invention seek to provide an alternative garment connector arrangement.
- In one aspect, the present invention provides a waterproof garment connector arrangement for attaching a distal garment part to a main body of a garment, the connector arrangement including:
-
- a first part having a first outward facing recess and an inward facing protrusion;
- a second part having an outer engagement member for being received in the first outward facing recess and an inner engagement member for engaging the protrusion, the outer engagement member including a second outward facing recess at least partially accommodated in the first outward facing recess in use; and
- an annular member for fitting into the second outward facing recess, the arrangement being such that the annular member, in use, urges the outer engagement member against a wall of the first outward facing recess to secure the first part to the second part;
- wherein the first part extends from one of the distal garment part and the main body of the garment and the second part extends from the other of the distal garment part and the main body of the garment.
- Preferably the second part is resiliently deformable. The second part may have a Shore hardness of 45-75 but may fall outside of this range depending upon the type of material being used to form the annular member.
- The second outward facing recess may have an entrance having a width that is less than a width of the annular member. The arrangement may be such that the entrance deforms in use to allow the insertion of the annular member into the second outward facing recess, whereafter the entrance resiles to hold the annular member in the second outward facing recess and/or to provide a generally smooth outer surface. The second outward facing recess may have a generally partially circular transverse cross-section that corresponds in shape to the transverse cross-section of the annular member. The annular member may be an O-ring.
- The second part may be configured to be deformed during connection to the first part to slide over the wall of the first outward facing recess and the protrusion, whereafter the second part resiles to engage the first outward facing recess and the protrusion to hold the first and second parts together.
- In the embodiment, the first part is resiliently deformable.
- The first part may have a Shore hardness of 45-75 but may fall outside of this range depending upon the type of material being used to form the annular member.
- Other Shore hardnesses than specified for the first and second parts may be used. Generally, the second part may have a Shore hardness that is the same as the first part, although this is not essential. As an alternative, the shore hardnesses of the first and second parts may be different from each other, and, for example, the first part may have a Shore hardness that is 15% greater than the second part.
- The wall of the first outward facing recess and the protrusion of the first part may be configured to be deformed during connection to the second part, whereafter the wall of the first outward facing recess and the protrusion resile. Such an arrangement may allow a straightforward coupling procedure of the first part to the second part.
- The first part may include an abutment formation facing the protrusion for abutting in use an end wall of the second part, the arrangement being such as to hold the second part in engagement with the protrusion. This enhances the coupling together of the first and second part.
- The first part and the second part in the embodiments are annular, and the first and second outward facing recesses extend circumferentially.
- The distal garment part may comprise a glove or wrist seal; a foot-receiving part (sock or boot) or ankle seal; or a head-receiving part (hood) or a neck seal.
- The protrusion may be inclined.
- The embodiment allows the distal garment part to be easily connected to the main body of the garment in a waterproof manner.
- The garment may be a dry suit, a semi dry suit, a wet suit, an immersion suit, a survival suit or other protective suit. Semi dry suits are basically wet suits that have seals in the wrists and neck. These suits allow in a limited amount of water but restrict the flushing of water in the neck and wrist by using seals in these areas.
- In the embodiment to be described, the annular member fits into the second outward facing recess, and the arrangement is such that the annular member urges the outer engagement member against a wall of the first outward facing recess to secure the first part to the second part and thereby eliminates ingress and egress of water between the inside and outside faces of the first part and second part (where the wall of the first outward facing recess is) when connected together. Advantageously, the annular member has an inner circumference that is less than the circumference of the second part at the base of the second outward facing recess and this exerts a compressive force around the outside of the second part, thereby locking the protrusion in place. This arrangement may ensure that when a tensile or pulling force is applied between the first and second parts and along the axis of the parts they are not able to separate. Typically, the force that might be applied is that which might be encountered in normal use of the garment or when doffing and donning the garment.
- In a further aspect, the present invention provides a wet suit, immersion suit, survival suit, dry suit or semi dry suit including at least one connector arrangement of the type discussed above, the distal garment part comprising a glove, a wrist seal, a foot-receiving part, an ankle seal, a head-receiving part or a neck seal of the suit.
- According to a further aspect, the present invention provides a method for attaching a distal garment part to a main body of the garment using a waterproof garment connector arrangement as described above. The method includes pushing the first part and the second part together such that the outer engagement member is received in the first outward facing recess and the inner engagement member engages the protrusion. The method then includes subsequently inserting an annular member in the second outward facing recess, such that the annular member urges the outer engagement member against the wall of the first outward facing recess to secure the first part to the second part.
- For a better understanding of the present invention an embodiment will now be described by way of example, with reference to the accompanying drawings, in which:
-
FIG. 1 shows a front view a waterproof garment including a main body part covering the trunk, arms and legs of the wearer, and detachable gloves, foot-receiving parts and head-receiving parts; -
FIG. 2 shows a side elevational perspective view of a garment connector arrangement having a first part and a second part, the parts being connected together; -
FIG. 3 shows a side elevational perspective view of the first part of the garment connector; -
FIG. 4 shows a side elevational perspective view of the second part of the garment connector; -
FIG. 5 shows a plan view of an annular member for fitting to the second part; -
FIG. 6 shows a partial cross-sectional view of the connected first and second parts; and -
FIG. 7 shows a partial cross-sectional view of the connected first and second parts in a modified embodiment. - In the drawings, like elements are generally designated with the same reference signs.
- A dry suit in accordance with an embodiment of the invention is shown generally at 1 in
FIG. 1 . The dry suit comprises amain body 3 that accommodates the trunk, arms and legs of the wearer. - Distal garment parts may be detachable from the
main body 3. Such distal garment parts may comprisegloves 5, foot-receiving parts/boots 7 and a head-receiving part/hood 9. The present invention is particularly, but not exclusively, applicable to connectingglove parts 5 and foot-receiving parts 7 to themain body 3. - It should also be appreciated that, where the embodiment is described in relation to a dry suit, the invention is also applicable to other types of garments where waterproof connections are desirable.
- In the embodiment the
gloves 5 and foot-receiving parts 7 are connected to themain body 3 by waterproof or substantially fluid-tight garment connectors 10. Such awaterproof garment connector 10 is shown in more detail nFIGS. 2 to 6 . - Briefly, the
garment connector 10 comprises afirst part 11 that extends from the one of the distal garment part (glove 5 o foot-receiving part 7 in the embodiment) and themain body 3, and asecond part 13 that extends from the other of thedistal garment part 5/7 and themain body 3. The distal garment part could also be the head-receivingpart 9. - Many dry suits on the market today are fitted with neck seals rather than head-receiving parts, wrist seals rather than gloves and ankle seals rather than foot-receiving parts. Such seals are usually constructed in a latex rubber, silicone, neoprene or some other elastic material having a smooth surface face on at least one side. The distal garment part may be a neck seal, a wrist seal or an ankle seal.
- The
first part 11 and thesecond part 13 may be integrally formed with thedistal garment part 5/7 or themain body 3 from which they extend or may be permanently attached thereto by welding, adhesive or any other suitable means. - In addition to the
first part 11 and thesecond part 13, thegarment connector 10 further includes an annular member, which in the embodiment is an O-ring 15. As is known, an O-ring is formed of rubber or a similar resiliently deformable material and has a circular transverse cross-section. Although in the embodiment an O-ring 15 is used, annular members of different configurations and cross-sections may also be used in accordance with the invention. - The
first part 11 will now be described in more detail. Thefirst part 11 includes a hollowtubular connecting section 17 which connects thefirst part 11 to the waterproof garment—either themain body 3 or thedistal garment part 5/7. The connectingsection 17 may be integrally formed therewith or permanently attached thereto, as described above. At the distal end thereof thefirst part 11 has a firstcircumferential wall 19 and a secondcircumferential wall 21 spaced therefrom along the central axis of thefirst part 11, thewalls recess 23 therebetween. The sides of thewalls first part 11, although the side of the first wall may have a inward inclination. Theopposite sides walls walls - The
first part 11 further comprises an inward facing protrusion 25 (seeFIG. 6 ), which extends generally opposite to thefirst wall 19. Further, thefirst part 11 includes anabutment formation 27 which extends inwardly, generally opposite to thesecond wall 21. Theabutment formation 27 includes a distal end-facingwall 29 which extends generally perpendicular to the central axis of thefirst part 11. Theprotrusion 25 may be inclined towards the distal end-facingwall 29, as shown inFIG. 6 . - In
FIG. 6 the distal end-facingwall 29 includes alip 30. However, it should be understood that thelip 30 may be omitted, so that the end-facingwall 29 is substantially straight and forms a substantially right-angled corner with the main inward facing surface of thefirst part 11. - The
second part 13 will now be described in more detail. Thesecond part 13 includes a hollowtubular connecting section 31 which connects thesecond part 13 to the waterproof garment (either thedistal garment part 5/7 or the main body 3). The connectingsection 31 may be integrally formed with the waterproof garment or may be permanently attached thereto in the manner described above. - The
second part 13 includes anouter engagement member 33 that is received in the first outward facingrecess 23 of thefirst part 11 when thesecond part 13 is coupled to thefirst part 11, and as shown best inFIG. 6 . The outer engagement member is generally U-shaped, and has a shape and size corresponding generally to the internal shape and size of the first outward facingrecess 23. The relative sizes and shapes may be selected so that there is an interference fit between theouter engagement member 33 and the first outward facingrecess 23. Theouter engagement member 33 includes a second outward facingrecess 35 that is at least partially accommodated in the first outward facingrecess 23 when thesecond part 13 is coupled to thefirst part 11. The second outward facingrecess 35 has a part circular transverse cross-section. Theentrance 37 to therecess 35 has a transverse width which is less than the transverse width of the centre of therecess 35. - The
second part 13 further includes aninner engagement member 39 that engages theprotrusion 25 when thesecond part 13 is connected to thefirst part 11. The distal end of theinner engagement member 39 terminates in awall 40 that abuts theabutment wall 29 of theabutment formation 27 of the first part. Theinner engagement member 39 includeswall 41 facing generally opposite to wall 40, but inclined away therefrom, for engaging theprotrusion 25. - In use, the
first part 11 and thesecond part 13 are connected together by bringing them towards each other along the central axis. The front wall of theouter engagement member 33 initially contacts theinclined surface 24 of the first wall of thefirst part 11, and due to the resilient deformability of these parts, theouter engagement member 33 slides over thefirst wall 19. In a similar manner, theinner engagement member 39 of thesecond part 13 slides over theprotrusion 25 of thefirst part 11. When thefirst part 11 and thesecond part 13 are fully pushed together, the deformed parts resile and take the positions shown inFIG. 6 , so that theouter engagement member 33 is accommodated in the first outward facingrecess 23 and theinner engagement member 39 engages theprotrusion 25 and theabutment wall 29. - The O-
ring 15, which will have been loosely lying over either the tubular connectingsection 17 of the first part or thetubular connecting section 31 of the second part, will then be moved along the central axis, so that it rolls or slides over theinclined surface 22 of thesecond wall 21 of the first part, or over a correspondinginclined wall 43 of the second part, thereby stretching the O-ring 15, until the O-ring 15 reaches theentrance 37 to the second outward facingrecess 35. At this point, the material at theentrance 37 deforms, due to the pressure exerted by the stretched O-ring 15, and the O-ring falls into therecess 35, the material at theentrance 37 of therecess 35 thereafter resiling. - When the O-
ring 15 is accommodated in therecess 35 it urges theouter engagement member 33 against thefirst wall 19 andsecond wall 21 of the first outward facingrecess 23 to secure thefirst part 11 to thesecond part 13. This will also tend to urge theprotrusion 25 against theinner engagement member 39. In this way, secure and watertight coupling between the first part and thesecond part 13 is accomplished. - Preferably, the O-
ring 15 has an inner circumference co (as seen inFIG. 5 ) that is less than the circumference cp (as seen inFIG. 4 ) of thesecond part 13 at the base of therecess 35. Such an arrangement exerts a compressive force around the outside of thesecond part 13, thereby locking theprotrusion 25 in place. This arrangement may ensure that when a tensile or pulling force is applied between the first 11 and second 13 parts and along the central axis of theparts - Preferably, the tube forming the O-
ring 15 has a cross-sectional diameter d (as seen inFIG. 6 ) that is greater than the maximum internal width w of therecess 35. The O-ring 15 may have a cross-sectional area that is greater that the corresponding cross-sectional area of therecess 35. Such an arrangement tends to secure thefirst part 11 to thesecond part 13 by pushing the walls of therecess 35 apart slightly so that they press against thewalls - To uncouple the
first part 11 from thesecond part 13, the O-ring 15 is removed from the second outward facingrecess 35. Theouter engagement member 33 can then be pulled away from the first outward facingrecess 23, thereby releasing theinner engagement member 39 from theprotrusion 25, and allowing thefirst part 11 and thesecond part 13 to be moved away from each other. - In a modification to the first embodiment, the inward facing
protrusion 25 may be replaced with a modifiedprotrusion 25A, as shown inFIG. 7 . Theprotrusion 25A is not inclined but has asurface 25B which extends generally perpendicular to the central axis of thefirst part 11 and substantially parallel to the distal end-facingwall 29. In this embodiment, theinner engagement member 39 includeswall 41 facing generally opposite to wall 40, and extending generally parallel thereto, for engaging theprotrusion 25A. - In the embodiment the first part has a Shore hardness of 45-75, and the
second part 13 also has a Shore hardness of 45-75. However, it should be understood that these are only example values, and other values may be used. Thefirst part 11 and thesecond part 13 may have substantially identical hardnesses. Alternatively, the first part may be slightly (e.g. 15%) harder than the second part. - The
first part 11 and/or thesecond part 13 may be formed of R/F (Radio Frequency) weldable Estane® PU (polyurethane) but could be any plastics material including a polyether or polyurethane or rubber based materials, or any other material that has similar physical properties to the aforementioned materials. - The O-
ring 15 may be produced typically but not restricted to direct injection moulding. The O-ring 15 may have a Shore hardness in the range of 45-80. The O-ring 15 may have a Shore hardness greater than the Shore hardness of the first and/orsecond parts
