The swivel connector 120 may be a part of the central axis 110. The central flow path 130 is coaxial with the central axis 110. The radial flow path 140 extends radially from the central flow path 130. The swivel connector 120, the central flow path 130, and the radial flow path 140 may be connected as a continuous flow path for the fluid within the drum 100. In this respect, see the black arrows in FIG. 2 illustrating the flow path through the hose reel.

The hose reel further comprises a swivel 200 for a supply of the fluid, the swivel 200 being connected to the swivel connector 120. The swivel 200 may be arranged to the swivel connector 120 for supplying fluid from a supply of fluid through the swivel to the swivel connector 120, the central flow path 130, and the radial flow path 140. The swivel 200 is a component that leads fluid from a stationary part to a rotating part. In this present exemplary embodiment, the swivel 200 is connected to a stationary fluid supply via the hose 20. In this exemplary embodiment, the swivel 200 is also connected to the stationary housing 400, for example housing part 430 with a screw 460. The swivel 200 is connected to the swivel connector 120 to provide fluid to the hose 30 reeled around the rotatable drum 100. The swivel 200 may thus be directly arranged/coupled to the drum 100. The fluid flow through the swivel 200 may be directly coupled to the central flow path 130 of the fluid flow through the drum 100.

According to one embodiment, the hose reel may further comprise a connector 300 for connecting the radial flow path 140 with the hose 30 to be reeled up onto the hose reel. The connector 300 may be a separate part of the drum 100, i.e. not an integral moulded part of the drum 100. The connector 300 may connect the fluid flow through the drum 100 with the hose 30 to be reeled up around the drum 100. The connector 300 may be part of a continuous flow path from the fluid supply to the hose 30 reeled up, that is from the fluid supply via the hose 20 to the swivel 200, to the swivel connector 120, to the central flow path 130, to the radial flow path 140, to the connector 300, to the hose 30 to be reeled up. According to one embodiment, the flow path through the hose reel consists of these; see the black arrows in FIG. 2 illustrating the flow path through the hose reel.

According to one embodiment, the connector 300 is form fitted into the drum 100. That is, the shape of the connector 300 fits into an opening of the drum 100, the shape and the opening be made for each other. In addition, for example, the connector 300 may be secured into the drum 100 by fastening means, such as a screw, a snap-fit, or similar. The connector 300 is part of the drum 100 and the connector 300 is also part of the fluid flow path through the drum 100. The flow path for the fluid through the drum 100 comprises, according to one embodiment consists of, the flow path through the swivel 200, the flow path through the swivel connector 120, the central flow path 130, the radial flow path 140, and the flow path through the connector 300.

According to one embodiment, the connector 300 comprises a first, preferably straight, flow path 310 and a second, preferably straight, flow path 320.

The first flow path 310 and the second flow path 320 are connected at one end and they form an angle 330 between each other in the range of 45 to 135 degrees. This may best be taken from FIG. 2, where the flow through the first flow path 310 and the flow through the second flow path 320 are indicated by black arrows. According to one embodiment, the angle 330 is preferable 90 degrees, or about 90 degrees, or about 80 to 100 degrees, or 70 to 110 degrees. The other ends of the first flow path 310 and the second flow path 320 may be connected to the radial flow path 140 and to the hose 30 to be reeled up, respectively.

According to one embodiment, each of the swivel 200 and the connector 300 may comprise one of the following group: a U-shaped holder 240, 340, a clamp, a quick fit coupling, and a nipple, for connecting the supply and/or the hose, respectively. Connecting to the supply is preferably done by using a hose 20 that is connected to the swivel 200. The nipple may be a nipple for a coupling, such as a quick fit coupling. The U-shaped holder 240, 340 holds the end of the hose 20, 30 with the middle part of its two legs, while the top and bottom of the U-shaped holder is secured in the drum 100, or swivel 200, or connector 300, respectively. In this way a hose 20, 30 may be secured to the hose reel 10. In this way the swivel 200 may be connected to the swivel connector 120.

According to one embodiment, the hose reel 10 further comprises a housing 400 for housing the drum 100. The housing 400 comprises an opening 410 to allow access to the connector 300. The connector 300 in the drum 100 may be accessed by a user through the opening 410 in the housing 400 to connect or disconnect a hose 30. In this way the housing 400 must not be dismantled from the drum 100 when a hose 30 is serviced or connected.

According to one embodiment, the drum 100 comprises a drum stop opening 150 and the housing 400 comprises a housing stop opening 450. This is best illustrated in FIG. 1. The drum stop opening 150 and the housing stop opening 450 are arranged to align with each other in a position where the connector 300 aligns with the opening 410 of the housing 400. By rotating the drum 100 relative to the housing 400, the two stop openings 150, 450 are aligned. Subsequently, an object may be inserted into both stop openings 150, 450, such as for example a screw driver. Hereby the drum 100 is locked in position relative to the housing 400 in a position where a user can access the connector 300 through the opening 410 of the housing 400. These stop openings 150, 450 makes it easy to access the connector 300, because the drum 100 may be spring loaded to rewind the hose. When accessing the connector 300 the stop openings 150, 450 assure that the hose reel suddenly does not rotate the drum 100.

According to one embodiment, the housing 400 comprises a first part 420 and a second part 430. The first part 420 and the second part 430 are housing parts. The first part 420 comprises an axis 440 supporting the drum 100 on the central axis 110. This may best be taken from FIG. 3. The second part 430 comprising means 460 to hold the swivel 200. The axis 440 may be a support 440. In this way the housing 400 supports the relative rotation of the drum 100 within the housing 400 around the central axis. The first part 420 may be half the housing 400 and the second part 430 may be the other half of the housing 400.

According to one embodiment, the flow path through the swivel 200, the central flow path 130, the radial flow path 140, and the first and second flow paths 310, 320 of the connector 300 together form a continuous flow path for the fluid, through the drum 100. The continuous flow path is illustrated as black arrows in FIG. 2. The continuous flow path may be an uninterrupted, open, flow path for the fluid.

The continuous flow path may be absent of any mechanism in the fluid flow used to connect or create the continuous flow path, absent of any reductions in size. That is, the continuous flow path is absent of any sudden changes of its formation, the continuous flow path has a continuous form, shape, or opening. The flow path through the hose reel, through the drum, has a, more or less, constant diameter.

That is, a perpendicular cut through the flow path, anywhere along the flow path, is always disk shaped, with a perpendicular cut through the turns of the flow path naturally being somewhat oval shaped. In this way the fluid flows through the hose reel with a minimal resistance. The continuous flow path may start at the swivel 200 and may end with the connector 300. The continuous flow path is part of the fluid flow from the fluid supply, and the hose 20 connected to the swivel 200, to the hose 30 to be reeled up, connected to the connector 300. According to one embodiment, the continuous flow path consist out of the flow path through the swivel 200, the central flow path 130, the radial flow path 140, and the first and second flow paths 310, 320 of the connector 300.

According to one embodiment, the drum 100 comprises of a first drum part 160, a second drum part 170, and the connector 300. The connector 300 may be form fitted into one of the drum parts 160, 170. The drum 100 may have one or more drum parts. All or some drum parts may be moulded.

According to one embodiment, the connector 300 is arranged completely within the drum 100. The connector 300 may be form fitted completely within the drum 100, i.e. not protruding beyond the drum 100 in the radial direction. The connector 300 may be flush with a bottom 180 of the drum 100. The drum bottom 180 is the bottom 180 upon which the hose 30 is to be reeled up around. As the connector 300 is within the drum 100 no obstruction exist for reeling up the hose 30, and access to the connector 300 can be arranged by the opening 410 of the housing 400. The connector 300 may be connected to the radial flow path 140 of the drum 100. For example one of the connector 300 or the radial flow path 140 may be T-shaped and the other part may be complimentary shaped so that they can connect. An o-ring, or similar, may be used to ensure no leakage of fluid between the connector 300 and the radial flow path 140.

Turning to the method, FIG. 4 is a diagrammatic illustration of the method for connecting a hose to the hose reel according to an exemplary embodiment of the present disclosure. The first two method steps 510 and 520 are taken in order, and the other method steps 530, 540, 550, and 560, may be taken in any order, even before, after, or between the first two method steps, as long as it makes technical sense. The method as illustrated in FIG. 4 comprises: 510 a first method step, rotating the drum 100 relative to the housing 400; 520 a second method step, connecting a hose 30 to the connector 300; 530 a method step of aligning the two stop openings 140, 440; 540 a method step of inserting an object, for example a screw driver, into the two stop openings; 550 a method step of connecting a hose 20 to the swivel 200; and 560 a method step of attaching a hose to the hose reel. The steps 530 and 540 are normally taken between steps 510 and 520. The step 550 may be taken any time and step 560 is taken normally last. The method steps are explained in more detail below.
