Definitions

  • the invention relates to a device for automatic winding flexible Strands, especially for winding a hose, with a Drum which is rotatably mounted in a housing and with a Return spring, in particular spiral spring between housing and drum, which is tensioned by the drum when the strand is unwound, and with a device blocking the drum in the winding direction, which can be released by pulling on the wound strand.
  • the device mentioned at the outset is used Art provided that one of the two is relative to each other rotatable parts a locking element pivotable against spring force and the other part is assigned at least one counter element, that is firmly connected to the other part and depends on the direction of rotation comes into operative connection with the locking element.
  • This configuration allows the hose or the Strands up to a certain length, then when reversing the direction of rotation the blocking element becomes active. It can be done by pulling it off again be resolved in such a way that a blocking effect occurs again, when the strand or hose is unwound another piece or so that afterwards the automatic winding process is initiated via the spiral spring.
  • the locking element mounted on the housing and the counter element of the rotatable Drum.
  • the locking element as a rocker arranged on the housing are formed, the pivot axis in an elongated hole of the housing is mounted displaceably in the circumferential direction.
  • the spring associated with the locking element be fixed in place on the housing approximately in the middle of the slot, depending on the position of the rocker in the circumferential direction one or the other lever arm of the rocker and this into the movement path of the counter element.
  • This configuration enables a lever arm of the rocker on free end with a pawl, the other with a pawl is so that when the pawl engages with the counter element or when the pawl interacts with the counter element in each case a shifting of the rocker is initiated, which then either in its locked position for engagement with the counter element or in their Switch position comes in which the counter element in the winding direction can pass freely under the pawl, in the opposite direction, that is then if the hose is pulled further but ensures that the rocker is moved in the circumferential direction and then its pawl is pressed into the path of movement of the counter element and a The drum rewinds for the purpose of winding the hose initially prevented.
  • the Counter flank of the locking hook end of the rocker as a freewheel flank can be designed to swing the unwinding of the To cause pawl from the path of movement of the counter element.
  • the counter element can be used as one in both Rotation directions formed with a hook-shaped part his. But it is also possible to make the counter element from two in the circumferential direction offset from each other, in opposite directions building pointing hook.
  • the circumferential distance the two partial counter-elements can be larger than the length of the rocker be formed so that only one of the partial counter elements between the locking hook end of the rocker and the switching edge located. It is advantageous that each of the locking hook end and flanks of the counter element facing away from the switching end of the rocker also form as freewheel flanks, so that at Passing through the counter element in the corresponding circumferential direction the rocker is only lifted in against the spring force not shifted in another of the two layers in the circumferential direction becomes.
  • the division of the counter element into two separate sub-elements allows a larger pull path to release the lock for subsequent automatic winding without such a pulling path already between the mutually facing inner flanks of the seesaw must be given.
  • Invention also provided that the drum via a transmission gear is connected to a fan wheel that increases the Air resistance and to brake the drum speed when winding Driven by the drum at a significantly higher speed becomes. This measure can ensure this, especially if the gear ratio between drum and fan wheel on the one hand and on the other hand, the surface of the fan wheel blades is matched to one another are that at a defined pulling speed of the Strands no significant counterforce is generated, but with increased Winding speed achieved a sufficient braking effect is that the winding speed is not a certain amount exceeds.
  • the design can, especially if as a transmission gear a planetary gear is provided be that for example when unwinding the strand with Walking speed of the user the speed of the fan wheel none significant resistance generated, while at a substantial higher winding speed caused by the spiral spring Resistance can become so great that the winding speed is limited to an unproblematic value.
  • the one used as a brake The fan wheel is simple in construction and practically maintenance-free.
  • a drum 2 is mounted, the radially outward projecting side tabs 2a, which for holding one on the Serve drum 2 wound hose 3.
  • the free end 3a of the The hose is removed from the housing 1 by a guide device 4 extractable in the direction of arrow 5.
  • the drum 2 rotates in the Clockwise. To wind up the hose 3, the drum in Turned counterclockwise.
  • a locking device is provided, on the one hand from a pawl 8, on the other hand from counter elements 9, 9a, which, as can be seen in FIG. 1, in the illustrated Position when the drum 2 rotates counterclockwise engage and further turning for the purpose of winding prevent.
  • the pawl 8 is in the embodiment shown as a rocker formed, which is pivotable about the axis 10.
  • the axis 10 itself is in a slot 11 firmly connected to the housing 1 Leadership led.
  • the rocker 8 is also under the effect of a Compression spring 12, which presses rocker 8 with a pressure piece 12a.
  • the compression spring 12 is arranged in a radial plane through which Axis 13 runs, which is also the axis of rotation of the drum 2. This Radial plane runs in the middle of the slot 11.
  • the pressure piece 12a therefore loads the rocker 8 depending on the position of the pivot axis 10.
  • the rocker 8 is by the compression spring 12 acted in the sense of a pivoting movement counterclockwise.
  • the pivot axis 10 is located in the area of the right end of the elongated hole 11, then the rocker 8 becomes a pivoting movement acted clockwise by the compression spring 12.
  • An air wheel brake is provided that is too large 3 and 4 can be seen better.
  • Fig. 4 also shows that the drum 2 on a Shaft 18 is mounted, at least over part of its length with a Hollow chamber 19 is provided, the outside in a connecting piece 20 ensures the supply of water under pressure, which then through the openings 21 of the chamber 19 in the on a connecting piece 22 of the Arrive drum 2 attached inner end of the hose 3 can.
  • 5 to 8 show a modified embodiment of a Locking device for the drum 2, but not in operation is different than the locking device, based on the previous figures has been briefly described.
  • a rocker 80 is provided, which on a Axis 10 is mounted, which in turn can be moved in an elongated hole 11 is mounted, in the central plane of which the compression spring 12 is arranged.
  • the rocker 80 has compared to the embodiment of the 1 to 4 differently formed hook ends 81 and 82, wherein the hook end 81 a locking hook and the hook end 82 a Switch hook forms.
  • Different from the previously described embodiment is also that firmly connected to the drum 2
  • Counter element 90 does not consist of two polar spaced individual counter elements 9 and 9a is constructed, but from a single double hook element, however, this is also symmetrical to a radial plane is trained. The operation of this embodiment is now brief explained.
  • the pawl 82 will removed from the path of movement of the counter elements 90, as shown in FIG. 6 is shown.
  • the mutually engaging flanks of the counter element 90 and pawl 82 are designed so that a secure polar displacement of the axis 10 in the slot 11 guaranteed and that the pawl 82 is also unhindered in the new polar position from that formed by the movement path of the counter-elements 90 Can swing out circular ring.
  • the operation of the embodiment shown in FIGS. 1 to 4 with two polar-spaced sub-elements 9 and 9a is the same as the level described.
  • the polar distance of the sub-elements 9 and 9a is greater than the length of the rocker 8, so that there is only one at a time the sub-elements between the blocking edge and switching edge of the rocker 8 located.
  • the counter flanks are counter elements 9, 9a and the outer flanks of the rocker 8 are designed as freewheel flanks, so that the rocker 8 is only raised against the spring force, but not shifted to the other of the two polar positions can.
  • the freewheel flanks can, for example, in a simple manner due to the edges of the sub-elements clearly inclined against a radial plane be given.
  • the division into separate sub-elements 9, 9a allows a larger pull path to release the lock for subsequent automatic winding without such a pull path between the mutually facing flanks of the rocker 8 must be given.
  • the air wheel brake explained with reference to FIGS. 1 to 4 is limited by the in the winding device, the air resistance increases rapidly Winding speed to an unproblematic value.
  • the fan wheel is simple in construction and maintenance-free.
  • the limitation of the winding speed ensures, as at the beginning already executed, a safe function of the locking mechanism described and avoids its excessive burdens.
