DEVICE FOR WATERPROOFLY CONNECTING A GLOVE TO A CUFF OF A DRYWALL SUIT

Description

[0001] The invention relates to a device for waterproofly connecting a glove to a cuff of a dry suit, a method for removing a first ring from a second ring of such a device, and a dry suit comprising a device as described above.

[0002] Drysuits are diving suits in which the diver essentially has no contact with the water underneath. This ensures that the diver is protected as much as possible from cold water. Such drysuits regularly include glove systems to protect the diver's hands from the cold water. The glove systems are usually detachable from the drysuits. Divers exiting the water are often cold and therefore have limited motor skills to operate the couplings. This is made more difficult by the fact that divers using drysuits wear glove systems and insulated gloves in addition to the waterproof gloves. Thus, the divers wear several gloves on top of each other. Consequently, it is difficult for the divers to operate delicate coupling devices.

[0003] Detachable connections between gloves and dry suits are known from the prior art.

[0004] Documents DE 19701343 C2 and US 6,715,159 B2 each disclose a device for watertightly connecting a glove to the cuff of a drysuit. The device, equipped with a coupling, makes it possible to easily connect a glove to the cuff of a drysuit, creating a watertight seal. The coupling has the disadvantage that opening it is relatively difficult and cumbersome. Document EP 3 437 502 A1 discloses the features of the preamble of claim 1 and also a device for watertightly connecting a glove to a cuff. This device also includes a coupling mechanism. The coupling mechanism has the disadvantage of requiring very delicate operation. This is difficult for a diver who often gets cold and wears several gloves.

[0005] Document US 2020 / 0317310 A1 discloses a waterproof connector for a diving suit with a lighting device.

[0006] The object of the invention is to overcome the disadvantages of the prior art and in particular to create a device with which a waterproof glove can be connected and disconnected from a cuff of a dry suit without tools and without requiring delicate operation.

[0007] The problem is solved by a device for watertight connection of a glove to a cuff of a dry suit, a method for removing a first ring from a second ring of such a device, and a dry suit comprising a device as described above.In particular, the problem is solved by a device for watertightly connecting a glove to a cuff of a drysuit, comprising a first ring that can be sealed and attached to a cuff or the glove, a second ring that can be sealed and attached to a glove or a cuff, and a sealing ring, wherein the first ring has a first groove extending circumferentially on the outside and wherein the second ring has a second groove extending circumferentially on the inside, and wherein the first ring and the second ring can be inserted into one another such that the sealing ring for sealingly connecting the first ring to the second ring is arranged simultaneously extending in the first groove and the second groove. The first ring and / or the second ring comprises at least one projection which is arranged on the outside of the first ring and / or on the outside of the second ring.The first ring and / or the second ring have at least one recess into which the projection of a first ring and / or the projection of a second ring of a second identical device can be inserted when the first ring and the second ring of the device are nested inside each other.

[0008] Such a device creates a watertight seal between the glove and the cuff of a drysuit and is easy to close and, in particular, easy to release. The sealing ring can be an O-ring, typically made of rubber, a rubber compound, or an elastomer. The first and second rings can be made of plastic, for example, by injection molding. Alternatively, the first and second rings can be made of metal or a composite material. Any durable, corrosion-resistant material can be used.

[0009] The projections of the first ring and / or the second ring can be designed as ribs and have a height, a width, and a length (circumferentially), with the length being significantly greater than the width and height. This results in an elongated, rib-like shape for the projections. The at least one recess also has a length (circumferentially), a height, and a width, with the length being significantly greater than the height and width. This results in a recess shape that corresponds to the shape of the ribs.The longitudinal, lateral, and vertical dimensions of the projection of the first ring and / or the second ring and the recess can be of similar dimensions, with the longitudinal, vertical, and lateral dimensions of the projection of the first ring and / or the second ring being slightly smaller than the longitudinal, vertical, and lateral dimensions of the recess, so that the projection of the first ring and / or the second ring can be inserted into the recess. The dimensions can be chosen such that the projection can be inserted into the recess in a substantially form-fitting manner.

[0010] The first and second rings can be circular. They can also be polygonal. They can also be oval. The crucial point is that the first and second rings can be nested inside each other.

[0011] The first and second grooves can each have a square cross-section. The first and second grooves can also each have a rectangular cross-section. The first and second grooves can also each have a polygonal cross-section. It is also possible for the first and / or second grooves to each have a square, a rectangle, or a polygon with rounded corners. Preferably, the cross-sections of the first and second grooves are semicircular. Preferably, the first and / or second groove is designed such that the sealing ring can be inserted into the first and / or second groove in a form-fitting manner.

[0012] The recess of the first ring of the device and / or the second ring can be designed such that the recess is limited by the first ring and the second ring when the device is nested together.

[0013] By limiting the recess with the first ring and the second ring in the assembled state, it is ensured that the projection of the second ring, when the recess is inserted, can be arranged so that it touches the first ring and the second ring, thus allowing a user to apply a force to the first ring and the second ring.

[0014] The recess can be bounded by the first and second rings in such a way that the boundary area of ​​the recess of the first and second rings is essentially identical. It is also possible that the first or second ring has no recess, while the other ring has a recess.

[0015] The at least one projection and / or the at least one recess can be arranged on circular segments of the first ring and / or on circular segments of the second ring, which constitute less than 80%, preferably less than 50%, and particularly preferably less than 30% of the respective total ring.

[0016] This arrangement, in which the cutouts only cover a portion of the circular segment of the first and / or second ring, prevents the ring from being unduly weakened. This ensures that the first and / or second ring maintains its full cross-section over the largest possible circular segment and is only weakened by the cutouts in a small area of ​​the segment. This allows for an advantageous and stable design and manufacturing process for the first and / or second ring.

[0017] The first ring of the device and / or the second ring of the device can have two to six projections. The second ring of the device can preferably also have three projections. The first ring of the device and / or the second ring of the device can have two to six recesses. The first ring and / or the second ring can preferably also have three recesses.

[0018] The number of two to six, preferably three, protrusions or recesses ensures that, regardless of how the rings are mounted on the drysuit or glove, a user can easily and simply arrange a protrusion and a recess accordingly by means of a slight rotation of the glove or the cuff of the drysuit.

[0019] The first ring can have a longitudinal axis perpendicular to the first groove, and the second ring can have a longitudinal axis perpendicular to the second groove. The projections and / or recesses can be arranged concentrically to the longitudinal axis of the first ring and / or concentrically to the longitudinal axis of the second ring.

[0020] The concentric arrangement of the recesses and / or projections to the longitudinal axis of the first and / or second ring ensures that the device is easy to manufacture and handle.

[0021] The device can be designed such that at least one projection of the device extends radially further from the first ring and / or the second ring than all other parts of the second ring. The device can also be designed such that all projections of the device extend further from the first ring and / or the second ring than all other parts of the second ring.

[0022] This ensures that the protrusions can be inserted into the recess(s) easily, safely and without complications.

[0023] The device can be designed such that the at least one projection and the first ring are formed in one piece; and / or that the at least one projection and the second ring are formed in one piece.

[0024] This has the advantage that the second ring can be easily manufactured and is stable and durable because the projection(s) are not connected to the second ring by fasteners and there is no interface.

[0025] The first ring and / or the second ring can, for example, be manufactured using injection molding. Other manufacturing methods are also conceivable.

[0026] The object of the invention is further achieved by a method for removing a first ring from a second ring of a device as described above. The method comprises the following steps: A: Holding a first device as described above, wherein the first ring and the second ring are in the nested position; B: Holding a first ring of a second device and / or a second ring of a second device as described above; C: Inserting at least one projection of the first ring of the second device or of the second ring of the second device into at least one recess of the first device, wherein the first ring of the second device and / or the second ring of the second device has a longitudinal axis perpendicular to the second groove, the longitudinal axis of the second ring of the first device and the longitudinal axis of the first ring of the second device and / or the longitudinal axis of the second ring of the second device are preferably arranged substantially parallel and are particularly preferably displaced translationally in parallel;D: Performing a rotational movement of the longitudinal axis of the first ring of the second device and / or the second ring of the second device, wherein the projection of the first ring of the second device or the projection of the second ring of the second device is rotated in the recess of the first ring of the first device and / or in the recess of the second ring of the first device, thereby exerting a force on the first ring of the first device and on the second ring of the first device, respectively; E: Separating the first ring of the first device from the second ring of the first device.

[0027] Such a procedure is simple and safe to carry out.

[0028] The projection of the second ring can be inserted into the recess of the first device by aligning the longitudinal axes of the first ring and the longitudinal axes of the second ring essentially parallel and then translating them in parallel. It is also possible to insert the projection of the second ring into the recess of the device by rotating it about its longitudinal axis. Alternatively, the projection can be inserted into the recess of the first device by a combination of a parallel translational movement and a rotational movement.

[0029] In process step D, the longitudinal axis of the first ring of the second device and / or the longitudinal axis of the second ring of the second device can be rotated on a plane which is essentially parallel to the longitudinal axis of the second ring of the first device.

[0030] This movement ensures that the projection is advantageously rotated within the recess, thus applying force to both the first and second rings of the first device. This allows the first ring to be separated from the second ring of the device particularly easily and simply.

[0031] The object of the invention is further achieved by a dry suit comprising a device as described above. Such a dry suit is particularly advantageous because the glove system can be easily detached from the dry suit.
