Description

The invention relates to a closure device for detachably connecting a first part to a second part. The invention is particularly suitable for detachably connecting a first part with a second part from the field of sports, marine, wildlife and / or industry.

A closure device of the aforementioned type is used in many areas of daily life. If an article, such as an accessory, a piece of equipment and / or a tool, is not intended for permanent attachment to a person and / or other object, then a simple and reliable manner of detachably attaching the article to the person and / or searched for the further object. In particular, it is desirable to releasably secure equipment to, for example, a bicycle, a stroller, a motor vehicle, and / or a wheelchair. Also in dog leashes, in the rigging of sailing ships, in the attachment of sails when surfing or kiting, in the attachment of objects in diving, in the attachment of items in the hunting area, in the attachment of equipment in the military field, in equestrian sports, the Trekking, parachuting and / or aerospace engineering in general, such closure devices are desirable. Even people who carry tools with them, want a reliable and detachable attachment of tools such as vests. Also, for example, in the construction industry such closure devices for releasably securing ropes for guiding components desirable.

From the DE 43 12 032 C2 For example, a closure device for detachably connecting a first part to a second part is known. The known closure device has a first closure unit with a pin, which can be brought into engagement with an engagement recess on a second closure unit. When attaching the pin urges a locking element aside, which comes after making the engagement of the pin of the first closure unit with the engagement recess of the second closure unit back to a normal position in which the engagement of the pin is locked with the engagement recess. To release the pin from the engagement recess, the locking member can be actuated to release the pin and remove it from the engagement recess.

From the EP 2 833 754 B1 For example, a closure device for releasably connecting two parts with a first closure unit and a second closure unit is known. The first closure unit can be attached to the second closure unit for closing the known closure device and held in a closed position on the second closure unit. Furthermore, the known closure device has a first engagement projection with undercut of the first closure unit and a second engagement projection with undercut of the second closure unit, wherein the first engagement projection for closing in an engagement direction with the second engagement projection is engageable and in the closed position in a form-fitting manner with the second engagement projection engaged. Furthermore, the known closure device has a blocking element arranged on the second closure unit, which is moved out of a basic position by engagement with the first closure unit when the first closure unit is attached to the second closure unit, so that the first engagement projection engages with the second engagement projection in FIG Intervention can be brought. The first engagement projection arrives at or after preparation of the engagement back to its normal position to lock in the normal position the positive engagement of the first engagement projection with the second engagement projection against the engagement direction. Between the first closure unit and the second closure unit, magnetic means configured to assist in attaching the first closure unit to the second closure unit by providing a magnetic attraction force act.

From the DE 10 2007 041 613 A1 For example, a coupling device with a spherical end fitting is known, which is attached to one end of a first segment. The spherical end fitting is insertable through a receiving opening into a receiving part located at an associated end of a second segment. The size of the receiving opening corresponds essentially to the extent of the end fitting. The receiving part is provided with a slide, which reduces the free cross-section of the receiving opening after insertion of the end fitting to a free cross section, which is smaller than the extension of the end fitting. The end fitting is thereby held in the receiving part, so that a positive connection between the first segment and the second segment is made.

From the WO 2014/128508 A2 For example, a closure device for detachably connecting a dog collar to a leash is known. The known closure device has a first closure unit with a longitudinal axis. Along the longitudinal axis extends a clamping device, which is designed in the manner of a clothespin. The clamping device has clamping elements on one end. Further points the known closure device on a second closure unit with a circumferential groove. In a closed position of the known closure device, the second closure unit is received in a receiving chamber of the first closure unit. In the closed position, the clamping elements of the clamping device engage in the circumferential groove of the second closure unit and thus prevent a release of the second closure unit from the first closure unit.

It has been found that none of the known closure devices ensures release of the first part from the second part under full load. Rather, it is not or only very poorly possible to solve the first part of the second part under full load in the known closure devices. Furthermore, a relative movement of the first part to the second part in the closed position of the known closure devices is hardly or not possible.

The invention is therefore based on the object to provide a closure device for releasably connecting a first part with a second part, in which a release of the first part of the second part is ensured under full load and / or in a relative movement of the first part to the second part is ensured in the closed position of the closure device.
