Definitions

  • the invention relates to a device for removing plaster from a wall, with an essentially consisting of a support and cover plate housing with a handle and two in the housing in a straight line in opposite directions to each other, mechanically oscillating, moved with removal tools tool carriers.
  • Devices of the type mentioned serve primarily to level and / or structure the top of a freshly plastered wall when the plaster has dried after a few hours but has not yet hardened. This finishing of plaster walls is particularly necessary if the plaster is sprayed onto the wall to be plastered by machine.
  • a plaster processing device with the features mentioned above is known from DE-A-24 53 262.
  • all previously known mechanical devices for removing plaster have the disadvantage that they are much too heavy and their handling is laborious, which is why the plasterer is still a hand-held scraper in most cases (for example according to US Pat. No. 2,983,943) grips a fingerboard that can be comfortably guided with one hand and studded with steel pins, even if he has to plan the plaster layers with muscle power.
  • Even the device known from DE-A-24 53 262 is so heavy due to the use of an electric motor with a downstream transmission that it has to be held and guided with two hands on two handles.
  • the invention is therefore based on the object of providing a device for removing plaster from a wall which is light, so that it can be held and guided by an operator with a single hand.
  • each tool carrier is coupled as a drive element to at least one separate cylinder / piston arrangement which is connected via hose lines to a remotely located pressure medium source with a downstream control device, in that the tool carrier is symmetrical to one are arranged perpendicular to the direction of movement of the tool carrier center plane of the device and that the single handle on the top of the cover plate of the housing is arranged centrally.
  • both the pneumatic or hydraulic pressure generator and the valve device controlling the movement of the cylinder / piston arrangements are arranged remotely, so that these parts do not have to be held by the operator .
  • This alone can achieve a very large reduction in weight compared to other known devices.
  • the device can also be made very compact in a size comparable to the hand cleaning scratches by using so-called mini-line units as drive elements, in which in a housing block a cylinder with a piston that can be loaded on both sides or two parallel cylinders with pistons that can be loaded on both sides, but each running on both sides and are preferably formed or supported in holding bodies for the piston rods ending in the tool carrier with additional guide rods for the holding bodies.
  • mini-line units allow a compact and space-saving design of the device, which results in a further noticeable weight saving.
  • the separate drive of the two tool carriers and their separate arrangement on the device allow the masses which are moved in opposite directions to one another to be of exactly the same size, and the movement curves of the two drive members to be precisely matched to one another.
  • the vibrations perceptible by the operator on the single handle of the device are therefore minimal and practically exclusively the effects of different resistance values occurring for a limited time, which affect the individual tools from the machined wall and which are also noticeable in the case of a hand cleaning scratch.
  • the housing can practically be limited to a cover plate which on one side has the only and centrally arranged handle and on the other side the guide and cylinder bodies of the cylinders / pistons. Orders orders.
  • the bearing points for the piston rods and the guide rods can be sealed well, so that safe operation of the drive elements is ensured even in the dusty atmosphere that arises here.
  • Another significant advantage of the subject matter of the invention is that the frequency of the oscillating movement of the two tool carriers can be changed, the adjustment being able to be carried out in a manner known from pneumatic or hydraulic control devices.
  • the working rhythm of the device can thus be set or readjusted in a frequency range free of resonance frequency.
  • the two tool carriers at their opposite edges can expediently be extended to protective walls which overlap one another in each operating position.
  • the device shown has a trough-shaped housing 10 with a cross section shown in FIG. 3, which forms with its central part a cover plate 11, on the top and outside of the housing 10 a bracket-like handle 12 is attached at a central point.
  • the cylinder body 13 and 14 of two cylinder / piston arrangements are spaced apart and symmetrical to a central plane M, which corresponds to the section line 111-111, arranged in the interior of the channel-shaped housing 10 so that the from the Cylinder bodies 13 and 14 projecting piston rods 15, 16 are aligned with one another in the longitudinal direction of the channel-shaped housing 10.
  • grid-like scraping tools 26 projecting laterally beyond the housing 10 are interchangeably fastened, which are provided with crossing webs 27, which can best be seen in FIG Form scraping edges, not shown, of which a part is effective in one direction and a part in the other direction of movement.
  • crossing webs 27 which can best be seen in FIG Form scraping edges, not shown, of which a part is effective in one direction and a part in the other direction of movement.
  • other types of tools can also be arranged.
  • the two cylinder / piston assemblies are connected with their cylinder bodies 13 and 14 in a manner not shown via hose lines to a remotely located compressed air generator and a control device connected downstream of it, which causes the double-acting piston with its piston rods 15 and 16 an oscillating movement in the direction of 1 and 2 registered double arrows 28 issued.
  • the control device is set so that the oscillating and transmitted to the tool carriers 23 and 24 with their scraping tools 26 of the aligned cylinder / piston arrangements always take place in opposite directions.
  • Both tool carriers 23 and 24 are extended in the middle part of the device on their opposite sides to protective walls 29 and 30 which overlap and make it more difficult for dust to penetrate into the housing space 31 between them (FIG. 2).
  • the tools 26 can also be attached directly to the holding bodies 19-22, so that the parts 23, 24 can be omitted entirely or can only form cover walls.
  • the control device (not shown) for the pneumatic cylinder / piston arrangements is designed in a manner known per se so that the oscillation frequency of the two arrangements can be changed simultaneously and to the same extent.
  • the device is gripped on the single handle 12 by an operator with one hand.
  • a switch (not shown) can be arranged on the operating handle 12, with which the two cylinder / piston arrangements with their cylinder bodies 13, 14 can each be switched on simultaneously.
  • the compressed air connections, the switching valves and the control valves of the control device and the compressed air generator itself are not shown for reasons of clarity. They are located all - with the possible exception of an on / off switch - away from the housing 10 of the device.
  • hydraulic cylinder / piston arrangements can also be provided as drive elements.
  • FIG. 4 and 5 show a modified embodiment of the device in which the two tool carriers 23 'and 24' in the interior of the U-shaped housing 10 'are slidably mounted in roller bearings 32 without tilting. They each have a mounting web 33 shown in FIG. 5, with which they protrude through a slot 34, which is sealable on both sides of the web ends, of a housing cover wall 35, with which the housing 10 'is closed toward the working side of the device.
  • the scraping tool 26 ' is exchangeably fastened to the mounting web 33 of each tool carrier.
  • the cylinder / piston arrangement assigned to each tool carrier 23 'and 24' is not shown. It can be arranged, for example, in the housing end regions 36 and 37 designated in FIG. 4.
  • the cylinder of the cylinder / piston arrangement can also be formed in the body of the tool carrier 23 'and 24'.
  • the cylinder / piston arrangements can also be mounted in the end regions of the housing on the upper handle side 38 of the U-shaped housing 10 'in each case in the extension of the centrally arranged handle, not shown in FIGS. 4 and 5, and through a housing slot be coupled to the ball-bearing tool carriers 23 'and 24'.
  • FIGS. 4 and 5 results in a very flat design with good protection of the drive arrangements by the housing cover wall 35.
