Problems solved by technology

[0004] A disadvantage of the known hose reels described above is that once the operator starts winding, the drum tends to speed up, making it difficult for the operator to manually stop the hose, often making the hose, which is usually fitted with a terminal nozzle, The end slams into the housing, possibly damaging the housing and spray head as a result
At this time, the above-mentioned "slamming" and wear problems will occur again.

Embodiment Construction

[0031] The hose reel shown in the accompanying drawings comprises a housing 1 which rotatably supports a drum 3 which is pressed in an angular rest position by a rewind spring 2 and has a rotatable axial It is connected to the flange 4 of the locking disc 5 which also has teeth 8 which can engage with corresponding teeth 9 on the housing 1 .

[0032] Said flange 4 comprises a raised surface portion 51 which is engageable with a corresponding protrusion 52 of the locking disc 5 during the unwinding and rewinding phases of the hose, said flange 4 also comprises a cam 6 which Engage with the corresponding cam 7 on the lock disc 5 (Fig. 8-12). The lock disc 5 has an inner sleeve 11, which is rotatably and axially installed on the cylindrical connecting portion 12 of the flange 4, and a pre-compressed separation spring 10 is provided between the lock disc 5 and the flange 4 for The locking disc 5 is kept axially spaced from the flange 4, thereby keeping the teeth 8 of the locking ...

Abstract

A hose reel is described comprising a support casing (1), a drum (3) rotatably fitted inside said casing (1) and connected to it by elastic rewinding means (2). The drum (3) provides a flange (4) integral with it and couplable in rotation with a locking disc (5) equipped with teeth (8) engageable with opposing teeth capable of stopping its rotation. Elastic separation means (10) are provided between the flange (4) and the locking disc (5) to keep the latter in a first position axially distanced from said flange (4), teeth and counter-teeth means (51, 52) mutually engaged to allow the flange (4) to draw the locking disc (5) into integral rotation with it, and cam and counter-cam means (6, 7) which, in the event of said flange exceeding a predetermined threshold speed cause the axial displacement of said locking disc (5) into a second position adjoining said flange (4) in which its teeth (8) engage with said opposing teeth (9) to produce the consequent stopping of the rotation of said drum (3).

Description

technical field [0001] The present invention relates to elastically rewinding hose reels with an automatic stop mechanism. Background technique [0002] A hose reel comprising a drum rotatably connected to a housing is a very useful tool when one needs to use very long hoses. [0003] Hose reels are known for winding a hose, the drum / housing being connected by a resilient mechanism which forces said drum to rotate in a direction which facilitates rewinding part or all of the unrolled hose. [0004] A disadvantage of the known hose reels described above is that once the operator starts winding, the drum tends to speed up, making it difficult for the operator to manually stop the hose, often making the hose, which is usually fitted with a terminal nozzle, The tip slams into the housing, possibly damaging the housing and spray head as a result. [0005] Known hose reels include a hose speed reduction mechanism that reduces the speed of winding, but does not address the above-...
