Definitions

  • the invention relates to a device for height adjustment, with the aid of a pedestal plate can be adjusted continuously to the particular desired effective height.
  • the invention relates to a device according to Ansprüchs. 1
  • Podiums are used for concerts, plays or other cultural or sporting events to form an elevated stage. Such a stage can be used to provide a better view of the protagonists, such as an artist or a group of actors, but it can also be used as an elevated and limited public space. Podiums often have a height adjustment to adjust their height according to the purpose and the local conditions variable.
  • podiums In most cases, a larger number of podiums will be set up side by side. Especially with fixed stages, it is desirable to adjust the individual pods in their height without effort and advantageously even remotely controlled.
  • Such a stage which is thus actually a podium field, can then be brought up and down modularly, for example, via a computer, for example to present certain set pieces at fixed times. Also, this can shut down the entire stage when it is not needed.
  • the height adjustment of such pedestals is made via a scissors construction, which adjusts the height of the pedestal plate to the extent that arranged the inclination of the scissor-like Metal arms changes to each other.
  • these metal arms attached to the pedestal plate transfer the forces caused by the actuation of the height adjustment, the dead weight and the load located on the pedestal plate to a metal frame and the floor.
  • a self-rotation of such based on a scissors construction podiums is excluded because the pedestal relative to the frame is not rotatable in principle. Similarly, a self-rotation is avoided even in a fixed mounted stage field, but even at two with one edge gapless abutting platform plates and always between the same height adjustment without further facilities.
  • the aforementioned scissors-like height adjustments can indeed be adjusted continuously and via a drive.
  • They have the disadvantage that the force is introduced irregularly during the stroke, since the required lifting force depends on the inclination angle of the scissor-type arranged metal arms.
  • the power of a motor to drive the height adjustment must of course be dimensioned according to the lifting force required in the tip and is thus exploited only over a small part of the entire stroke.
  • powerful and expensive engines are used without the high power could be used advantageously, such as by a higher additional load.
  • a device for height adjustment of a pedestal plate according to the preamble of the claim is known from US-A-3 918 225 known.
  • a pedestal plate is provided, which is arranged on a telescopically extendable column, which is slidably disposed in a guide column and can be actuated with a pneumatic actuator.
  • the extendable column is provided with through holes into which a locking bolt can be inserted to lock the platform plate at the desired height.
  • the positioning bolt is received in a groove by a guide post at its upper edge to provide locking in an extended position.
  • From the US-A-6 082 051 is a foldable stage known, which is pivotable from a space-saving storage position into a deployed working position.
  • two pivotally interconnected Podestplattenmaschine are provided which form the entire pedestal in the unfolded position.
  • the two podium plate parts are connected to a linkage, which is connected at its two ends on the one hand with the podium plate parts and on the other hand with support feet, which in turn are hinged to the podium plate parts.
  • the Gepartie is formed in a conventional manner as a scissor construction and ensures in its unfolded position that the support legs form vertical supports for the podium panels.
  • the object of the invention is therefore to provide a height adjustment of a pedestal plate, which avoids the disadvantages listed and which therefore guarantees a uniform force distribution and thus uniform lifting performance with high reliability and durability.
  • the invention solves this problem by replacing the principle of the scissors construction with the shear arms exposed to an uneven application of force, the principle of a telescopic guide or load recording.
  • Elements of a support column are telescopically arranged and connected by an engagement which is locked at the desired level of export. If the engagement is designed as a pair of force transmission element and matching guide groove inclined relative to the horizontal, the force can also be applied horizontally and is then converted by the engagement into stroke.
  • a telescopically extendable support and / or guide column is provided which is associated with a locking device for locking in an extended position.
  • the lifting force for extending the column is at least partially provided by an electric drive to adjust the podium height without effort and even remotely controlled.
  • the lifting force is preferably applied via thrust chains, a pneumatic system, a hydraulic system or an air bellows.
  • the lifting force can expediently also be applied at least partially by hand. So you can make yourself independent of electrical connection and adjust the desired height by eye.
  • the locking device is released at the one end of the column for retracting the column and then dissolves automatically when retracting telescopically. Then when retracting only the top part of the locking device needs to be unlocked by hand or electrically, and all other locking devices dissolve by an integrated mechanism when lowering, for example by automatically becoming active heels, bolts or similar devices.
  • the pedestal plate is secured against self-rotation and the support / guide column additionally designed as a lifting column, which is a first cylinder, which is connected at least indirectly rotatably connected to the pedestal, a second cylinder with different from the first cylinder diameter, the at least is indirectly connected to a bottom plate by means of a rotatable bearing, and a rotational force transmission means by means of which the second cylinder by means of a drive to absorb a torque and thus can be set in a rotational movement.
  • a lifting column which is a first cylinder, which is connected at least indirectly rotatably connected to the pedestal, a second cylinder with different from the first cylinder diameter, the at least is indirectly connected to a bottom plate by means of a rotatable bearing, and a rotational force transmission means by means of which the second cylinder by means of a drive to absorb a torque and thus can be set in a rotational movement.

  • Each cylinder is arranged in the cylinder next larger diameter, and the cylinders each have power transmission elements and against the horizontal inclined guide grooves, such that in each case a force transmission element engages in the associated guide groove of an adjacent cylinder.
  • the largest cylinder rotates, and this rotational movement is converted by the force transmission elements in the guide grooves in a lifting or lowering movement, in which the lifting column is screwed like a telescope or retracted.

  • the drive advantageously transmits the rotational force from a rotary drive source via a chain, belt or gear mechanism to the torque transmitting device.
  • the drive source can be spatially separated from the lifting column.
  • the drive source for the rotational force may include a motor to conveniently apply the lifting power and also to provide easy control of a remote control.
  • the possibility of manual operation is expediently provided, for example by means of a hand crank whose operation is preferably supported by a reduction.
  • the cylinders are preferably made of steel, brass or aluminum, and the power transmission elements are preferably made of a material which has a low coefficient of sliding friction with respect to the selected material of the cylinders, such as brass, bronze, steel or plastic.
  • a low sliding friction also has an advantageous effect on the necessary drive power as well as on the wear of the load-bearing parts, ie the force transmission elements and the guide grooves.
  • rollers can provide as power transmission elements.
  • a particularly good power transmission can be achieved by the angle of inclination of the or each guide against the horizontal is less than 45 ° and in particular between 10 ° and 35 °.
  • the force path is longer than the load path, which translates into a lower power requirement on the drive, in particular with a factor that combines a lower required power with a still rapid stroke transmission.

  • a particular embodiment of the invention provides a height adjustment with two or more respectively rotatably connected to the pedestal plate lifting columns whose guide grooves have the same angle of inclination and the rotational force transmission means are operated by two or more chains connected to a single drive. This guarantees a synchronous change in height of the two or more lifting columns, which automatically hold the platform plate in this way and secure against self-rotation.
  • the last-mentioned embodiment is particularly suitable for a podium surface of a few square meters, as it is often used, and offers a compact structure, a balanced weight and cost-saving height adjustment.

  • the cylinders have power transmission elements 34 and guide grooves 35, which will be discussed in more detail below.
  • the uppermost cylinder 33 is fixedly connected to the pedestal plate 10 by welding a lid to the cylinder 33 and screwing it to the pedestal plate 10.
  • the lowermost cylinder 31 is fixedly connected to a drive wheel 42 by welding, which in turn rests on a rotatable support 22, which consists of a greased slide bearing on a brass sheet. This bearing 22 is mounted on a bottom plate 20.
  • a drive chain 43 transmits the rotational movement of the working wheel 41 of a drive motor 40 the drive wheel 42.
  • the lowermost cylinder 31 is disposed in an octagonal storage cassette 21.
  • the cylinders 31, 32, 33 are placed in concentric relation to their common axis of symmetry, so that each cylinder is located within the next larger diameter cylinder.

But even the top cylinder 33 can not rotate without counterforce, because it is firmly connected to the pedestal plate 10, which is secured against self-rotation (for example, by concerns on another pedestal, the backup against self-rotation is not shown).
  • This counterforce is composed of frictional forces of the power transmission elements in the guide grooves and the weight of internal cylinders together.

  • the uppermost cylinder 33 and subsequently the others in the order of increasing diameter will be forced upward because they experience the lowest counteracting weight force, respectively.
  • the pedestal plate 10 is driven continuously upwards and can stably remain in any intermediate position by interrupting the drive and thus the rotational movement.
  • a locking of the motor 40 acts as a locking device, because the rotationally locked motor 40 prevents rotational movements of the cylinder 31, 32 and 33 and thus the Power transmission elements 34 can not move in the guide grooves 35.
