Abstract
Description
Technical area
[0001] The present invention relates to a portable clothesline with a cord winding mechanism housed in a housing. In particular, a foldable and lockable crank mechanism is disclosed, which enables a space-saving design and ergonomic operation. State of the art
[0002] Conventional clotheslines with a retractable mechanism often feature fixed or folding cranks. However, these are often not ergonomic, prone to breakage (crank arm), or make storage difficult due to their protruding design. Furthermore, they often lack a reliable locking mechanism to prevent the line from accidentally falling out. Object of the invention
[0003] The objective of the present invention is to provide a compact and easy-to-use clothesline with a foldable crank mechanism. The goal is to optimize the operation of the line's retraction and extension while simultaneously ensuring space-saving and safe storage of the crank. Solution to the task
[0004] This task is solved by a clothesline with the following features: 1. Foldable and retractable crank a. The crank is rotatably attached to the housing and can be moved between a flat, inserted position and an extended position. b. In the inserted position, the crank lies flat in the housing and does not protrude. c. In the unfolded position, it allows an efficient rotary movement to control the rope winding. 2. Ergonomic grip area a. The crank is designed so that it can be gripped on a cylindrical section when unfolding. b. This grip area allows an intuitive and effortless turning movement. 3. Mechanical locking a. When folded back into the closed position, the crank engages into the housing by means of a mechanical locking mechanism. b. This prevents the crank from opening or moving accidentally. c. This lock ensures compact and secure storage of the clothesline. 4. Housing with integrated cable guide a. The housing has an opening through which the rope is led out. b. The winding mechanism allows easy extension of the line by turning the crank counterclockwise and retraction by turning it clockwise.
[0005] These features enable a space-saving and functional solution for mobile use, especially for camping, trekking or traveling. Summary of benefits
[0006] The invention offers the following advantages over the prior art: 1. Space-saving design thanks to a retractable and flat crank 2. Easy handling thanks to an ergonomically optimized handle mechanism 3. Secure locking of the crank in the closed position 4. Efficient retraction and extension of the line through an intuitive rotating movement 5. Robust housing with integrated rope guide, optimized for outdoor use
[0007] The invention described here provides a portable clothesline with a foldable and lockable crank mechanism. Its space-saving design, ergonomic handling, and secure locking mechanism make it particularly suitable for travel and outdoor use and offer a simple solution for cord winding.
[0008] An embodiment of the invention is described with reference to Fig. 1 to 3. They show Fig. 1 The clothesline in half-closed position, Fig. 2 the clothesline in exploded view, Fig. 3 a partial view of the crank. List of designations 1 crank handle 2 housing covers 3 Crankshaft 4 Case back
Claims
[1] Portable clothesline with a housing in which a retractable line is guided, characterized by that the crankshaft (3) comprises a foldable and lockable crank (1) which is movable between an inserted and an unfolded position. [2] Clothesline according to claim 1, characterized by that the crank (1) lies flat on the crankshaft (3) and in the housing cover (2) in the inserted position and can be rotated in the unfolded position using an ergonomically designed handle area. [3] Clothesline according to one of the preceding claims, characterized by that the crank is locked by a mechanical locking mechanism which moves into a corresponding opening in the crankshaft (3). [4] Clothesline according to one of the preceding claims, characterized by that the crank is connected to the rope winding mechanism via a central axis of rotation in the crankshaft (3).
