Definitions

  • the invention relates to a cable reel, in particular cable drum, with a rotatably mounted on an axle drum body and a locking device for fixing the drum body relative to a fixed support body, wherein on the support body at least one locking element is arranged, in the context of a switching movement between a releasably fixable locking position and a releasably fixed release position can be positioned, wherein the locking element engages in the locking position to non-rotatable locking of the drum body in a locking structure on the drum body.
  • Locking devices for cable drums which are also referred to as brake devices, have been known for a long time. So is already out of the DE 73 00 862 a brake for blocking the drum is known, which consists of a threaded spindle which can be screwed by means of a knob against the outside of a disc of the cable drum and thereby blocks the drum.
  • the DE 197 08 654 A1 discloses a portable hose or cable drum having a rotatably mounted drum body with a ring gear, wherein the drum can be locked by two oppositely arranged, spring-loaded brake lever.
  • a braking device for blocking a drum body relative to a fixed support frame which has a pivotally mounted brake button, which is engageable with its front part in associated recesses on the flange of the drum body in engagement.
  • the brake button is designed in a special way, namely in the form of a rocker switch as a two-armed lever and is held in a recess on a bearing body of the support frame pivotally spring loaded in the open position and the locking position.
  • the object of the invention is to provide a cable reel of the type mentioned, the locking device for fixing the drum body relative to a fixed support body in a simple manner and functionally safe to use.
  • the cable reel according to the invention is characterized in that the locking element is designed as displaceable by a linear switching movement between the locking position and the release position locking slide.
  • the locking slide can thus be switched linearly back and forth in a simple manner between the locking position and the release position, wherein it is releasably fixed both in the locked position and in the release position.
  • the locking slide is very robust and also after numerous Switching operations functionally safe operable. This is especially important for use in harsh environments, such as construction sites.
  • the brake button is designed as a pivotally mounted brake button in the manner of a rocker switch, it is not excluded when used in harsh environment that breaks one of the actuating tabs of the brake button and thus the brake button can not be operated reliably.
  • the locking slide has an actuatable by the user, in a receiving opening on the drum body between the locking position and the release position displaceable operating portion and one of the locking structure of the drum body associated and engaging in the locking position there locking portion.
  • the operating portion and locking portion are integrally connected.
  • the locking slide is a one-piece component, wherein in the manufacture of actuating portion and locking portion are formed with the same. It is for example possible that the locking slide is a plastic component, for example plastic injection molded component.
  • the locking section is designed as a locking nose or locking projection projecting transversely to the switching direction from the actuating section in the direction of the drum body.
  • the arresting structure has a common arrangement around the axis of a drum disc of the drum body Arresting ring forming locking ribs, wherein the locking portion is disposed in the release position radially outside of the locking ring, while it engages in the locking position in the locking ring.
  • the locking nose on a forward towards the locking ribs open towards locking slot, wherein in the locked position engages one of the locking ribs of Arretierkranzes in the locking slot or the locking tab between two adjacent locking ribs on Arretierkranz. This ensures that locking in any position of the drum body with respect to the locking nose is possible, in which the locking slide is displaced into its locking position.
  • locking means and on a stationary on the support body arranged mounting plate counter-locking means are formed on the actuating portion, with which the locking slide is selectively fixed in the locked position or in the release position.
  • the locking means and counter-locking means are designed as locking means and counter-locking means.
  • other types of locking means or counter-locking means for example those which are to be actively operated by the user in order to effect a locking or unlocking.
  • the operating portion of the locking slide between the mounting plate and the support body is linearly displaceable incorporated and held by the mounting plate.
  • the mounting plate has a plurality of mounting holes, about which it is fastened by means of suitable fastening means, such as fastening screws on the support body.
  • the mounting plate is preferably a one-piece component.
  • the mounting plate made of plastic, for example, it is a plastic injection molded part.
  • the latching means and counter-latching means have a transversely aligned to the switching direction latching web and a spring-loaded latching tongue, wherein the latching web is engaged behind in the locking position on this side of the latching tongue and in the release position beyond the latching tongue.
  • the spring force of the latching tongue acts only in the switching movement between the locking position and the release position when the latching web is moved relative to the latching tongue.
  • the release position and also in the locked position there is no Federkraftbeetzleyung of the locking slide by the latching tongue, but it is here only a rear handle between the latching tongue and the latching web formed.
  • the locking slide is held spring loaded neither in the locked position nor in the release position and thus not dependent on a possibly over time decreasing spring force or clamping force. Between the latching tongue and the associated latching web play is present in the switching direction both in the locked position and in the release position.
  • the latching web is associated with the latching means on the actuating portion of the locking slide and the latching tongue of the mounting plate.
  • the latching tongue is formed on the actuating section and the latching web on the mounting plate.
  • the latching web is arranged in a recess on a rear side of the actuating portion. Conveniently, the latching web is not beyond the edge of the back of the actuating portion.
  • the latching tongue is integrally connected to the mounting plate, in particular formed out of the material of the mounting plate.
  • the spring effect of the latching tongue is thus achieved in this case by a solid-state joint between latching tongue and the area surrounding the mounting plate.
  • the latching tongue on a transversely projecting from the rest of the latching tongue in the direction of detent web locking projection. This latching projection can then engage behind the latching web when the locking position or optionally the release position is reached.
  • the mounting plate on a window-like opening which is penetrated by the locking tab.
