FIELD OF THE INVENTION

[0002] This invention relates to a weight integration system for buoyancy compensator devices, harnesses and weight systems used in underwater diving.

BACKGROUND OF THE INVENTION

[0003] In scuba diving, the use of weights for buoyancy compensation is a crucial aspect of achieving proper control and stability underwater. When a diver submerges, their overall buoyancy changes due to factors such as the wetsuit's buoyancy and the diving gear's air volume. To achieve neutral buoyancy, wherein the diver remains suspended at a constant depth without sinking or ascending, the diver uses weights to offset the positive buoyancy caused by the gear and the diver's body. By adding or removing weights prior to the dive, divers can ensure they have enough ballast to overcome their inherent buoyancy in order to descend and maintain a comfortable and safe position underwater.

[0004] In addition, a buoyancy compensator is used to fine-tune their buoyancy. The buoyancy compensator typically consists of an inflatable vest like harness worn by the diver. The compressed air cylinders are attached to the diver’s back via this harness.

[0005] By adding air to the buoyancy compensator, or releasing air from the buoyancy compensator, the diver is able to increase or decrease their buoyancy. This is useful to compensate for variability in their inherent buoyancy caused by wetsuit compression at depth as well as the lost weight of consumed breathing gas. In addition, the buoyancy compensator can be used to achieve positive buoyancy when resting at the surface.

[0006] Originally, the weights were attached to a webbing or rubber belt which was worn around the diver’s hips or waist. The belt utilises a quick release mechanism to enable it to be released and dropped quickly in an emergency, allowing the diver to ascend more rapidly. Alternatively, individual weights are held in weight pouches on the belt. In both cases the amount of weight can be adjusted by adding or removing individual weights.

[0007] In more recent times, it has become common for the buoyancy compensator to incorporate an integrated weight system, thus doing away with the need for a separate weight belt.

[0008] The integrated weight system generally consists of bottom or side opening pockets mounted on the buoyancy compensator vest and adapted to receive one or more lead weights, or more typically pouches containing the lead weights.

[0009] The pockets are then typically releasably closed using either a hook and loop (Velcro) fastener, or a quick release fastener such as a mechanical buckle, although other systems such as threaded cords have also been known to be used.

[0010] While integrated weight systems offer convenience and ease of use, they can also present some challenges and potential problems for divers.

[0011] An inherent problem faced with the existing pocket systems is that it is often difficult to achieve complete insertion of the weight pouch into the pocket, due to friction between the pouch and the inside of the pocket, adding to the general bulky nature of the buoyancy compensator system. Apart from the diminished convenience associated with performing this difficult operation, incomplete insertion of the weight pouches into the pockets also results in the pouches not being properly secured. This can lead to accidental loss of the weight pouches, potentially causing dangerous, unintended ascents. This is further exacerbated by the fact that it can be difficult to be sure that the pouch is, in fact, entirely inserted and secured as the pouch-in-pocket arrangement does provide some support even when not correctly secured, giving the diver the false impression that the pouch is correctly attached.

[0012] Additionally, difficulties have been experienced with the pocket closures:

[0013] The hook and loop system loses much of its strength when in water, resulting in the pockets opening at inopportune times, and the weight pouches falling out and being lost. In addition, the adhesive power of the hook and loop system wears out over time with use, exacerbating the problem.

[0014] The mechanical buckles are generally very secure, but the diver may experience difficulties clipping the buckle into place, especially when he is kitted up in his cumbersome diving kit. Often the assistance of another person is required. Furthermore, the buckle often proves difficult to release in emergency situations, due to complex release mechanisms, which are challenging to locate and activate. Integrated weight pockets can sometimes malfunction or get stuck, making it difficult to release the weights as needed.

[0015] While Integrated weight systems are designed to be streamlined, it is possible for the weights to shift during a dive and cause an imbalance in the diver's buoyancy and trim. This can affect the diver's ability to maintain proper positioning in the water and may lead to an uncomfortable or unsafe diving experience.

[0016] Proper weight distribution and careful buoyancy control are critical for a safe and enjoyable diving experience.

[0017] As a consequence, it is an object of this invention to provide a buoyancy compensator having a novel weight integration system which, at least partially, alleviates some of the abovementioned problems.

BRIEF SUMMARY OF THE INVENTION

[0018] In accordance with an example of the disclosure, there is provided a mechanism for releasably securing a weight-receiving pouch directly onto a buoyancy compensator vest. The mechanism comprises a first connecting element in the form of a linear rail. A second connecting element comprises a housing defining a slot/chaimel configured to be slidably received on the linear rail of the first connecting element. One of the first or second connecting elements is located on an external face of the buoyancy compensator vest. The other of the first or second connecting elements is located on/associated with the weightreceiving pouch.

10019] The linear rail and corresponding slot are preferably T shaped, to provide a T-slot interface between the first and second connecting elements.

[0020] One or more engaging formations may be located on the linear rail, configured to releasably engage with a corresponding engaging mechanism located in the housing of the second connecting element. The engaging mechanism is configured to retain the first and second connecting elements in active engagement with each other and to facilitate intentional disengagement of the first and second connecting elements from each other, by a user when required.

[0021] In one embodiment of the invention, the engaging formations may comprise one or more sets of teeth extending in the horizontal plane from opposite side edges of the head of the linear rail.

[0022] In this embodiment, the engaging mechanism may comprise a sprung loaded catch, comprising a pair of inwardly bent arms extending inwards from either side of the housing, each arm being pivotably mounted on a pivot point in the housing and biased towards the center of the housing by a spring, and oriented to facilitate free sliding movement of the second connecting element onto the first connecting element, and to engage with one or more of the teeth located on the linear rail to prevent sliding movement of the second connecting element away from, or off, the first connecting element.

[0023] The pair of arms may be connected to a release mechanism, configured to open the arms, release the teeth and thereby allow the second connecting element to slide off the first connecting element, on application of a release force. [0024] The release mechanism may comprise a pull handle, extending from the rear of the housing and connected to each arm by a connecting rod, configured to pull the arms open on application of a pulling force on the handle.

[0025] The release mechanism may alternatively comprise one or more “buttons” configured to extend through a side wall of the housing, and connected to each arm, wherein depression of the button by a diver acts to open the arms and release the engaging formations.

[0026] In an alternative embodiment of the invention, the engaging formations may comprise a set of ratchet teeth, extending from the upper face of the head of the linear rail.

[0027] In this alternative embodiment, the engaging mechanism comprises a sprung- loaded ratchet- catch, oriented to facilitate movement of the second connecting element onto the first connecting element, and to engage with the ratchet teeth located to prevent sliding movement of the second connecting element away from the first connecting element.

[0028] The first connecting element is preferably located on a waistband of the buoyancy compensator vest, and the second connecting element is preferably located on the weight pouch.

[0029] The first connecting element may be integrally formed on the external face of the waistband of the buoyancy compensator vest, alternatively the first connecting element may be mechanically connected to the external face of the waistband or to any other external face of the buoyancy compensator harness or bladder.

DETAILED DESCRIPTION OF THE INVENTION

[0049] The following description is provided as an enabling teaching of examples, is illustrative of principles associated with the examples and is not intended to limit the scope of the invention. Changes may be made to the embodiment/s depicted and described, while still attaining results of the present examples and/or without departing from the scope. Furthermore, it will be understood that some results or advantages of the present examples may be attained by selecting some of the features of the present examples without utilising other features. Accordingly, those skilled in the art will recognise that modifications and adaptations to the present examples may be possible and may even be desirable in certain circumstances, and may form part of the present application. [0050] For ease of reference and understanding, like features of the invention are indicated by like numerals.

[0051] Referring to Figures la, lb, 2a, 2b and 3a & 3b, existing prior art integrated weight systems generally consists of bottom or side opening pockets (102) mounted on the buoyancy compensator vest (100) adapted to receive one or more weight pouches (104).

[0052] Referring to Figures 2a and 2b, the weight pouch ( 104) is fitted with a mechanical buckle (106) that corresponds to a second mechanical buckle (108) on the buoyancy compensator (100) such that once the weight pouch (104) is inserted in the weight pocket (102), the two mechanical elements (106) &( 108) connect to each other and secure the weight pouch (104) in the weight pocket (102).

[0053] Referring to Figures 3a and 3b and in an alternative embodiment, the weight pouch (104) includes an integral mechanical element (108) that connects to a second mechanical element (110) that is integral to the weight pocket (102) on the buoyancy compensator (100).

[0054] Referring to Figures 4a, 4b, and 5 a and 5b, an example facilitates the releasable attachment of , a weight pouch (10) directly onto a buoyancy compensator vest (12).

[0055] The mechanism facilitating direct attachment, comprises a first connecting element in the form of a T shaped linear rail (16) having a head and a foot located on an external face of a waistband (18) of the buoyancy compensator vest (12) and a second connecting element, associated with the weight pouch (10), comprising a housing (22) defining a slot/channel (24) (see figure 6) at the back of the pouch. The slot (24) is slidably receivable on the linear rail (16) of the first connecting element to provide a T-slot like interface between the first and second connecting elements. This T-slot like interface between the two connecting elements fully supports the weight of the weight pouch (10) eliminating the need for an outer pocket or receptacle, to house the weight pouch. The foot of the linear rail extending through a mouth of the slot. The head forming undercut regions receiving portions of the second connecting element defining the mouth of the slot. [0056] The linear rail ( 16) is mechanically secured to the waistband ( 18) of the buoyancy compensator vest (12) by various means including, but not limited to, threading, stitching or moulding the first connecting element onto the waistband.

[0057] Referring to Figures 7a & 7b to 12a & 12b, one or more engaging formations are located on the head of the linear rail (16), to prevent the second connecting element and weight pouch (10) from sliding off the rail (16).

[0058] Referring to Figures 7a and 7b and 12a and 12b, and in one embodiment, the engaging formations comprise a plurality of teeth (30) extending in the horizontal plane from opposite side edges of the head of the rail (16).

[0059] Referring to Figures 8a and 8b, and in an alternative embodiment, the engaging formations comprise a single pair of teeth (32) extending from opposite side edges of the head of the rail (16).

[0060] Referring to Figures 9a, 9b, 10a, 10b and I la and 1 lb, and in further alternative embodiments, the engaging formations comprise a plurality of teeth (34) (ratchet teeth) extending from the upper face of the head of the rail (16).

[0061] The engaging formations (30, 32, 34) are configured to releasably engage with an engaging mechanism located in the housing (22) of the second connecting element. The engaging mechanism is configured to retain the T shaped linear rail (16) of the first connecting element in active engagement with the slot (24) in the housing (22) of the second comiecting element and to facilitate intentional disengagement of the first and second connecting elements from each other, when required.

[0062] Referring to Figures 7a and 7b, the engaging mechanism comprises a pair of inwardly bent arms (40) extending inwards from either side of the housing (22), each arm pivotably mounted on a pivot point (42) in the housing and biased towards the centre of the housing (22) by a spring (44). The arms (40) are oriented to facilitate forward sliding movement of the second connecting element in a first direction onto the rail (16) of the first connecting element and to engage with one or more of the teeth (30) to prevent unauthorised sliding movement of the second connecting element away in a second direction from/off the first connecting element.

[0063] The rear of each arm (40) extends through an aperture in the side wall (46) of the housing (22) to provide a release button (48). Referring to Figure 7b, depressing the buttons (48) pivots each arm (40) about its pivot point (42) against the bias of the spring (44), to open the arms (40) and release them from the teeth (30).

[0064] A pull handle (50) extends from the rear of the housing (22) and is connected to each arm (40) by connecting rods (52). The pull handle (50) is configured to pull and pivot the arms (40) open against the bias of the spring (44) and release the amis from the teeth on application of a pulling force on the handle (50). In this manner, by pulling on the handle (50), a diver can release the engaging mechanism and slide the second connecting element and associated weight pouch (10) off the rail of the first connecting element.

[0065] In this manner, the arms (40) may be released from the teeth (30) either by depressing the buttons (48) or by pulling on the handle (50), or by a combination of both actions.

[0066] Referring to Figures 8a and 8b, the engaging mechanism comprises a pair of arms (60) with clasps (62). Each arm (60) is pivotably mounted on a pivot point (64) in the housing. The arms (60) are linked to one another by a leaf spring (65), which extends between the pivot points (64) and biases the clasps (62) inwards towards the rail (16). The arms (60) are oriented to facilitate sliding movement of the second connecting element onto the rail ( 16) of the first connecting element), and to prevent unauthorised sliding movement of the second connecting element away from the first connecting element, by engaging with the teeth (32) once the weight pouch is fully inserted on the rail (16).

[0067] The rear of each arm (60) extends through an aperture in the side wall (46) of the housing (22) to provide a release button (66). Referring to Figure 8b, depressing the button (66) pivots the arm (60) on the pivot point (64) against the bias of the leaf spring (65), the arms (60) release the teeth (32). [0068] A pull handle (50) extends from the rear of the housing (22) and is connected to each arm (60) by connecting rods (68). The pull handle (50) is configured to pivot the arms (60) open against the bias of the leaf spring (65) on application of a pulling force on the handle (50) by the diver.

[0069] Referring to figures 9a and 9b, the alternative engaging mechanism comprises a spring-loaded ratchet-catch (70) oriented to facilitate sliding movement of the second connecting element onto the first connecting element and to engage with the ratchet teeth (34) to prevent sliding movement of the second connecting element and its associated weight pouch (10) off the rail (16) of the first connecting element.

[0070] The spring-loaded ratchet-catch (70) facilitates sliding movement of the second connecting element along the rail (16) in one direction, but resists movement in the other direction by catching on one of the teeth (34). Referring to Figure 9b, to release the second connecting element, the diver depresses the buttons (72) which disengages the ratchet-catch (70) and allows the second connecting element to slide freely.

[0071] Figures 10a and 10b depict an alternate embodiment of the embodiment of Figures 9a and 9b. In Figures 10a and 10b, the ratchet-catch (70) is connected to a release handle (74) by connecting rods (76) such that by either pulling the release handle (74) or sliding the provided buttons (78) (Figure 10b), the diver can release the ratchet-catch (70) and slide the second connecting element and associated weight pouch (10) off the rail (16).

[0072] Referring to Figures I la and 11b, and in a further alternative embodiment, the catches (80) of the ratchet catch (70) are connected to the release handle (74) by connecting rods (76). Referring to Figure 1 lb, the catches (80) can be activated to disengage the ratchet catch (70) by pulling the release handle (74) or depressing the buttons (82).

[0073] Referring to Figures 12a and 12b, in an alternative embodiment to that depicted in Figures 7a and 7b, the engaging mechanism comprises a pair of arms (90), the free ends of which terminate in clasps (92). Each arm (90) is pivotably mounted on a pivot point (95) in the housing (22) and is further connected to a connecting rod (98) at a second point (94). The connecting rods (98) are biased towards the arms (90) by helical springs (96), causing the arms (90) to rotate inwards around the pivot points (95) and biasing the arms inwards towards the rail (16) such that the clasps (92) engage with the teeth (30) of the rail (16). The clasps (92) are oriented to facilitate forward sliding movement of the second connecting element onto the rail (16) of the first connecting element and to engage with one or more of the teeth (30) extending from the head of the rail (16) to prevent unauthorised sliding movement of the second connecting element away from/off the first connecting element.

[0074] A pull handle (50) extends from the rear of the housing (22) and is connected to the connecting rods (98). In use, when a pulling force is applied to the pull handle (50), the pull handle (50) pulls the rods (98) against the bias of the spring (96) subsequently pivoting the arms (90) open about the pivot points (95) to release the clasps (92) from the teeth (30) of the rail (16). In this manner, by pulling on the handle (50), a diver can release the engaging mechanism and slide the second connecting element and associated weight pouch (10) off the rail of the first connecting element, if so required.

[0075] The application therefore provides a novel weight integration system for a buoyancy compensator vest, which allows for the complete removal or simplification of the prior art weight pocket (104) (depicted in Figures la, lb, 2a, 2b and 3a & 3b), or receptacle, from the buoyancy compensator, streamlining the buoyancy compensator, and simplifying the attachment and removal of the weight pouches.
