Official abstract text for this publication.
A hose reel includes a frame, a reel rotatably arranged within the frame and a rewind mechanism with a spring. A removable lid is attached to the frame and encloses an inside of the hose reel from all directions to prevent a user of the hose reel from accessing the inside of the hose reel. An axle is rotatable in relation to the reel. A first end of the spring is attached to the reel and a second end of the spring is attached to the axle. The axle has an outer end connected to the lid to prevent mutual rotation between the lid and the outer end in a direction which decreases the spring force of the spring.

The invention claimed is: 1. A hose reel, comprising: a frame, a reel rotatably arranged within the frame, and a rewind mechanism with a spring with a spring tension that increases when the reel is rotated within the frame in a first direction around a rotation axis while a hose is pulled out from the reel, and which spring tension decreases when the spring rotates the reel in a second direction within the frame to rewind the hose to the reel, wherein the hose reel comprises a removable lid which is attached to the frame and which together with the frame encloses an inside of the hose reel substantially from all directions to prevent a user of the hose reel from accessing the inside of the hose reel, and an axle which is rotatable in relation to the reel, and wherein a first end of the spring is attached to the reel and a second end of the spring is attached to the axle, and the axle has an outer end with engagement screws connecting the outer end of the axle to the lid to prevent mutual rotation between the lid and the outer end in a direction which decreases the spring force of the spring. 2. The hose reel according to claim 1 , wherein the axle includes at least the outer end and an inner end which are non-rotatably engaged to each other, and the outer end is an elongated part passing from an outside of the lid through a hole in the lid to engage with the inner end of the axle, such that a flange on the outer end contacts an outer surface of the lid, and the screws attach the flange to the lid. 3. The hose reel according to claim 1 , wherein the outer end of the axle is provided with corners for engaging a tool rotating the axle and providing pre-tension to the spring. 4. The hose reel according to claim 1 , wherein the hose reel is provided with a guide providing an outlet opening for the hose from the reel, an outer end of the hose is provided with a stopper preventing the outer end of the hose from being re-winded through the opening provided by the guide into the hose reel, and the spring is provided with a pre-tension rewinding the hose to the reel until the stopper contacts the guide and prevents further rewinding of the hose. 5. The hose reel according to claim 4 , wherein the hose reel is provided with a pre-tension hose and with an engagement part for attaching the pre-tension hose as an extension to the outer end of the hose, and the stopper is detachably attached to the hose for being removed to allow the outer end of the hose and the pre-tension hose attached to the hose to be re-winded to the reel for releasing the pre-tension of the spring. 6. The hose reel according to claim 1 , wherein the frame is provided with side openings providing access to the reel which is arranged in the frame, and the lid is shaped to cover the side openings while being attached to the frame. 7. A hose reel, comprising: a frame, a reel rotatably arranged within the frame, and a rewind mechanism with a spring with a spring tension that increases when the reel is rotated within the frame in a first direction around a rotation axis while a hose is pulled out from the reel, and which spring tension decreases when the spring rotates the reel in a second direction within the frame to rewind the hose to the reel, wherein the hose reel comprises a removable lid which is attached to the frame and which together with the frame encloses an inside of the hose reel substantially from all directions to prevent a user of the hose reel from accessing the inside of the hose reel, and an axle which is rotatable in relation to the reel, and wherein a first end of the spring is attached to the reel and a second end of the spring is attached to the axle, the axle has an outer end with at least one protrusion extending radially sideways from the outer end of the axle along an outer surface of the lid, the lid is provided with a hole having a shape corresponding to the shape of the outer end and the at least one protrusion, such that the outer end and the at least one protrusion may pass through the hole while the axle is rotated into a release position, and which prevents the outer end and the at least one protrusion from passing through the hole when the axle is not in the release position, and the lid is provided with a shoulder against which the at least one protrusion is pressed by the spring force when the spring of the hose reel is tensioned such that the outer end of the axle is connected to the lid to prevent mutual rotation between the lid and the outer end in a direction which decreases the spring force of the spring. 8. The hose reel according to claim 7 , wherein the hose reel is provided with a guide providing an outlet opening for the hose from the reel, an outer end of the hose is provided with a stopper preventing the outer end of the hose from being re-winded through the opening provided by the guide into the hose reel, and the spring is provided with a pre-tension rewinding the hose to the reel until the stopper contacts the guide and prevents further rewinding of the hose. 9. The hose reel according to claim 8 , wherein the hose reel is provided with a pre-tension hose and with an engagement part for attaching the pre-tension hose as an extension to the outer end of the hose, and the stopper is detachably attached to the hose for being removed to allow the outer end of the hose and the pre-tension hose attached to the hose to be re-winded to the reel for releasing the pre-tension of the spring. 10. The hose reel according to claim 7 , wherein the frame is provided with side openings providing access to the reel which is arranged in the frame, and the lid is shaped to cover the side openings while being attached to the frame.
