Description

[0001] The present invention relates to a handle device for a hose coupling element according to the preamble of claim 1 and a hose coupling device according to claim 5.

[0002] Fig. Figure 1A shows a perspective view of a prior art hose coupling element 1 in the form of a claw coupling element for hose lines with a conventional design known from GEKA-plus quick couplings and similar quick couplings. The hose coupling element 1 comprises an annular body 2 on which two laterally projecting claws 3, each with a claw hook 7, two laterally projecting coupling flanges 4, and a nozzle 5 are formed, and in which a sealing ring 6 is located. The two laterally projecting coupling flanges 4 extend around the circumference of the annular body 2 between one of the two claws 3 and a coupling flange beginning on which a coupling projection 8 is formed.

[0003] Fig. Figure 1B shows a perspective view of a prior art hose connection. To create the hose connection between two hoses, two such hose coupling elements 1 are used. The nozzles 5 of the two hose coupling elements 1 are each inserted into a hose end 9 of the hoses. The hose ends 9 are fastened to the nozzles 5 using hose clamps 10. The coupling flanges 4 of the hose coupling elements 1 are each pushed into a space between one of the claw hooks 7 and the annular body 2 of the other hose coupling element 1 in a rotational movement, thereby compressing the corresponding sealing rings 6. Coupling projections 8 are formed at the beginning of each coupling flange 4, which prevent the hose coupling elements 1 from accidentally detaching.

[0004] Overcoming the coupling projections 8 to release the connection of the hose coupling elements 1 requires a noticeable effort and can even cause pain in the hands.

[0005] The present invention is based on the objective of creating a handle device for a hose coupling element that makes it possible to release a hose coupling element of a hose connection without excessive effort, and a hose coupling device of a hose connection that can be released without excessive effort.

[0006] The problem underlying the invention is solved by a handle device with the features of the characterizing part of claim 1 and a hose coupling device with the features of the characterizing part of claim 5.

[0007] The invention relates to a handle for a hose coupling element with (at least) two claws and a nozzle, wherein the handle has a handle body with a (central) receiving opening for the nozzle (and the hose end of a hose) extending from one base to an opposite base, and wherein screw holes (with internal threads) are formed on the handle body for attaching the handle body to the nozzle by means of screws. Preferably, each of the claws has a claw hook (at a free end). Preferably, the handle body is essentially ring-shaped. Preferably, the handle body is made of plastic. Preferably, the base and the opposite base are arranged parallel. Preferably, the screw holes are radially oriented (and arranged in one plane). Preferably, the screw holes each have an internal thread.Preferably, a screw is provided in each of the screw holes. Preferably, at least three, and more preferably four, screw holes are provided at equidistant angular intervals around the circumference of the handle body. Preferably, the screws are countersunk in the screw holes, i.e., they can be screwed into the handle body to such an extent that they do not protrude from its outer surface while pressing the hose end against the nozzle in the receiving opening. Preferably, the outer surface of the handle body is provided with a grooved structure running in the direction of the axis of symmetry of the handle body to reduce the risk of fingers slipping when the handle is operated.Preferably, the receiving opening has a circular cross-section with a diameter large enough to accommodate the nozzles of conventional hose coupling elements, allowing the same handle to be used for different sized conventional hose coupling elements. Preferably, the diameter of the receiving opening is between 2.7 cm and 3.0 cm, more preferably between 2.8 cm and 2.9 cm.

[0008] In a preferred embodiment, two claw recesses are formed on the base. These recesses are designed to accommodate a portion of a claw from a conventional hose coupling element, pointing away from the claw hooks. Preferably, an annular recess is also provided on the base, extending around the receiving opening. This annular recess serves to receive a portion of the annular body of the hose coupling element. Without the annular recess, the claws of conventional hose coupling elements cannot be received in the claw recesses. Preferably, the annular recess is aligned with the claw recesses. The claw recesses preferably have a depth of at least 2 mm, and more preferably at least 3 mm.Advantageously, the claw recesses and the ring-shaped recess create space for attaching the hose end to the nozzle using a hose clamp.

[0009] In a further preferred embodiment, a projection is formed around the edge of the opposite base side, and a tool recess is provided in the projection. Preferably, the projection is aligned with the axis of symmetry of the handle body. The tool recess serves to insert a screwdriver, a socket with a receiving tool, or the like in order to fasten the hose clamp.

[0010] In a further preferred embodiment, a projection is formed around the edge of the base. Preferably, the projection is aligned with the axis of symmetry of the handle body. Preferably, the projection surrounds a (cylindrical) claw-receiving recess. Preferably, a portion of the two claws of a hose coupling element, pointing away from the claw hooks, can be received in this recess, with the claw hooks protruding from it. The claw-receiving recess preferably has a diameter between 55 mm and 60 mm and a depth of at least 5 mm, more preferably at least 1 cm.

[0011] The invention further relates to a hose coupling device with a hose coupling element having two claws and a nozzle inserted into a hose end, wherein the hose coupling device has a handle, the handle having a handle body with a receiving opening extending from one base to an opposite base and in which the nozzle and the hose end are received, and wherein screws are provided which extend through screw holes in the handle body and whose ends press against the hose end into which the nozzle is inserted in the receiving opening, thus securing the handle to the nozzle. Advantageously, two such hose coupling devices can also be connected without noticeable effort.The hose coupling device may further include the optional features of each embodiment and further development of the handle device.

[0012] In a preferred embodiment, two claw recesses are formed on the base side, in each of which one of the two claws is received.

[0013] In a preferred embodiment, a projection is formed around the edge of the base, surrounding a (preferably cylindrical) claw receiving recess in which the two claws are (partially) received. The claw receiving recess is preferably designed such that a portion of each of the two claws of the hose coupling element, pointing away from the claw hooks, is received in it, with the claw hooks of both claws projecting from the claw receiving recess. Preferably, the claw hooks project sufficiently from the claw receiving recess to allow two hose coupling devices to be coupled together.
