Description

The invention relates to a device for watertight connection of a glove to a cuff of a dry diving suit, a method for removing a first ring from a second ring of such a device, and a dry diving suit comprising a device as described above.

Drysuits are diving suits in which a diver has essentially no contact with the water underneath the drysuit. This ensures that a diver is protected as well as possible from cold water. Such dry diving suits regularly include glove systems in order to also protect the diver's hands from the cold water. The glove systems are mostly detachably attached to the dry suits. Divers who come out of the water often freeze and are therefore only able to operate the clutch to a limited extent. This is made more difficult by the fact that divers who dive with drysuits use glove systems and wear insulating gloves in addition to the waterproof gloves. Thus, the divers wear several gloves on top of each other. Accordingly, it is difficult for the divers to use delicate coupling devices.

Releasable connections of gloves to dry suits are known in the prior art.

The documents DE19701343C2 and US 6,715,159 B2 each disclose a device for watertightly connecting a glove to a cuff of a dry suit. The device equipped with a coupling makes it possible to easily attach a glove to a cuff of a drysuit to connect so that the glove is watertightly connected to the cuff. The coupling has the disadvantage that opening the coupling is relatively difficult and cumbersome. The document EP 3 437 502 A1 also discloses a device for watertightly connecting a glove to a cuff. This device also includes a coupling device. The coupling device has the disadvantage that it has to be operated very delicately. This is difficult for a diver who is often cold and wears several gloves on top of each other.

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 connected glove can be connected and disconnected to a cuff of a dry diving suit without tools and without filigree operation being necessary.

The object is achieved by a device for watertight connection of a glove to a cuff of a dry diving suit, a method for removing a first ring from a second ring of such a device and a dry diving suit comprising a device as described above.

In particular, the object is achieved by a device for the watertight connection of a glove to a cuff of a dry diving suit, comprising a first ring that can be sealingly fastened to a cuff or the glove, a second ring that can be sealingly fastened to a glove or a cuff, and a sealing ring, wherein the first ring has an outer peripheral first groove and wherein the second ring has an inner peripheral second groove and wherein the first ring and the second ring are such are plugged into one another, that the sealing ring for sealingly connecting the first ring to the second ring is arranged to run in the first groove and the second groove at the same time. 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 fitted into one another.

Such a device connects the glove to the cuff of a dry diving suit in a watertight manner and is easy to close and, in particular, easy to detach. The sealing ring can be an O-ring, which is typically made of rubber, a rubber compound or an elastomer. The first ring and the second ring can be made of plastic, for example by an injection molding process. The first ring and the second ring can also be made of metal or of a composite material. Any tough, corrosion resistant material can be used.

The projections of the first ring and/or the second ring can be designed as strips and have a height extension, a width extension and a length extension (in the circumferential direction), the length extension being significantly greater than the width extension and the height extension. This results in an elongated, strip-like shape of the projections. The at least one recess also has a length (in the circumferential direction), a height and a width, the length being significantly greater than the height and width. This results in a shape of the recesses that matches the shape of the strips corresponds. The length, width, and height of the protrusion of the first ring and/or the second ring and the recess may be of similar mass, with the length, height, and width of the protrusion of the first ring and/or the second ring being slightly less are as the length, the height and the width 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 selected in such a way that the projection can be introduced into the recess in an essentially form-fitting manner.

The first ring and the second ring can be circular. The first ring and the second ring can also be designed as a polygon. The first ring and the second ring can also be oval in shape. It is crucial that the first ring and the second ring can be plugged into one another.

The first groove and the second groove may each have a square cross section. The first groove and the second groove can each also have a rectangle in cross section. The first groove and the second groove can also each have a polygon in cross section. It is also possible that the first groove and/or the second groove each have a square, a rectangle or a polygon, with the corners being rounded off. The cross sections of the first groove and the second groove are preferably designed as a semicircle. The first groove and/or the second groove is preferably designed in such a way that the sealing ring can be inserted into the first groove and/or the second groove with a form fit.

The recess of the first ring of the device and/or of the second ring can be designed in such a way that the recess is delimited by the first ring and the second ring when the device is plugged into one another.

The delimitation of the recess by the first ring and the second ring when mated ensures that when the recess is inserted the protrusion of the second ring is locatable to contact the first ring and the second ring and so through a User a force on the first ring and the second ring can be applied.

The recess may be delimited by the first ring and the second ring such that the delimiting surface of the recess of the first ring and the second ring are substantially identical. It is also possible that the first ring or the second ring has no recess and the respective other ring has a recess.

The at least one projection and/or the at least one recess can be arranged on circle segments of the first ring and/or on circle segments of the second ring, which make up less than 80%, preferably less than 50%, particularly preferably less than 30% of the respective overall ring .

This arrangement, in which the recesses only make up part of the circle segment of the first ring and/or the second ring, does not unduly weaken the ring. This ensures that the first ring and/or the second ring has the full cross-section on the largest possible segment of a circle and is only weakened by the recesses on a small area of the segment of the circle. This enables an advantageous and stable design and manufacture of the first ring and/or the second ring.

The first ring of the device and/or the second ring of the device may have from two to six protrusions. The second ring of the device can also preferably have three projections. The first ring of the device and/or the second ring of the device may have from two to six recesses. The first ring and/or the second ring can also preferably have three recesses.

The number of two to six, preferably three, projections or recesses ensures that, regardless of how the rings are mounted on the dry suit or glove, a projection and a recess can be arranged correspondingly.

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

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

The device can be designed in such a way that at least one projection of the device projects radially further from the first ring and/or from the second ring than all other parts of the second ring. The device can also be designed in such a way that all projections of the device cantilever from the first ring and/or the second ring more than all other parts of the second ring.

This ensures that the projections can be inserted into the recess(es) in a simple, safe and uncomplicated manner.

The device may be configured such that the at least one protrusion and the first ring are integrally formed; and/or that the at least one projection and the second ring are formed in one piece.

This has the advantage that the second ring can be manufactured easily and is stable and durable because the projection or projections are not connected to the second ring by fastening means and there is no interface.

The first ring and/or the second ring can be manufactured, for example, by means of an injection molding process. Other manufacturing methods are also conceivable.

1. A: Vorhalten einer ersten Vorrichtung wie oben beschrieben, wobei sich der erste Ring und der zweite Ring im ineinander gesteckten Zustand befinden;
2. B: Vorhalten eines ersten Rings einer zweiten Vorrichtung und/oder eines zweiten Rings einer zweiten Vorrichtung wie oben beschrieben;
3. C: Einführen von zumindest einem Vorsprung des ersten Rings der zweiten Vorrichtung oder des zweiten Rings der zweiten Vorrichtung in zumindest eine Ausnehmung der ersten Vorrichtung, wobei der erste Ring der zweiten Vorrichtung und/oder der zweite Ring der zweiten Vorrichtung eine senkrecht zur zweiten Nut verlaufene Längsachse aufweist, die Längsachse des zweiten Rings der ersten Vorrichtung und die Längsachse des ersten Rings der zweiten Vorrichtung und/oder die Längsachse des zweiten Rings der zweiten Vorrichtung bevorzugt im Wesentlichen parallel angeordnet sind und insbesondere bevorzugt parallel translatorisch verschoben werden;
4. D: Ausführen einer Drehbewegung der Längsachse des ersten Rings der zweiten Vorrichtung und/oder des zweiten Rings der zweiten Vorrichtung, wobei der Vorsprung des ersten Rings der zweiten Vorrichtung oder der Vorsprung des zweiten Rings der zweiten Vorrichtung in der Ausnehmung des ersten Rings der ersten Vorrichtung und/oder in der Ausnehmung des zweiten Rings der ersten Vorrichtung gedreht wird und dabei jeweils eine Kraft auf den ersten Ring der ersten Vorrichtung und auf den zweiten Ring der ersten Vorrichtung ausübt;
5. E: Trennen des ersten Rings der ersten Vorrichtung vom zweiten Ring der ersten Vorrichtung.

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 procedure includes the following steps:

1. A: holding a first device as described above with the first ring and the second ring in the nested state;
2. B: Provision of a first ring of a second device and/or a second ring of a second device as described above;
3. C: Inserting at least one protrusion of the first ring of the second device or 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 running perpendicularly 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 particularly preferably parallel be translated translationally;
4. 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, whereby the protrusion of the first ring of the second device or the protrusion of the second ring of the second device in the recess of the first ring of the first device and/or is rotated in the recess of the second ring of the first device and thereby exerts a force on the first ring of the first device and on the second ring of the first device;
5. E: Separating the first ring of the first device from the second ring of the first device.

Such a method can be carried out easily and safely.

The projection of the second ring can be inserted into the recess of the first device by arranging the longitudinal axis of the first ring and the longitudinal axis of the second ring essentially parallel and then translationally displacing them in parallel. It is also possible that the projection of the second ring is inserted into the recess of the device by rotating the projection of the second ring around the longitudinal axis of the second ring. It is also possible that the projection is introduced into the recess of the first device by a combination of a parallel translational movement and a rotational movement.

In method 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 in a plane which is essentially parallel to the longitudinal axis of the second ring of the first device.

Such a movement ensures that the projection is advantageously rotated in the recess and thus a force is applied to the first ring and the second ring of the first device, respectively. As a result, the first ring can be separated from the second ring of the device in a particularly simple and uncomplicated manner.

The object of the invention is also achieved by a dry diving suit comprising a device as described above. Such a dry suit can be used particularly advantageously because the glove system can be separated from the dry diving suit in a particularly simple manner.
