Definitions

  • the invention relates to a wall slot device with a housing which has a first handle in a first end area and a second handle in a second end area, a drive unit for a slot tool consisting of at least one disk, and a drive unit which is connected to the housing and can be actuated by means of an electric switch Carriage against which the housing can be pivoted parallel to the disk plane of the slotting tool about a rotary bearing arranged in the first end region of the housing against the force of a spring element, a locking element being provided in the second end region of the housing to limit the housing and the carriage the second handle arranged locking switch is actuated.
  • a wall slot device with a two-handle housing, a drive unit connected to the housing and operable by means of an electric switch for a slot tool consisting of at least one disk and a slide is known.
  • the housing can be pivoted parallel to the disk plane of the slot tool about a rotary bearing against the force of a spring element, with the limitation of the pivoting movement a locking element is provided between the housing and the slide, which can be actuated by a locking switch arranged in one of the handles.
  • the drive unit of this known device can be switched on without a hand having to grasp one of the handles. There is a risk of injury if one hand grips one handle while the locking switch is actuated and the other hand swivels the carriage against the housing without the carriage resting entirely on the surface to be processed.
  • the rotating slot tool projecting above the slide can be positioned exactly according to a marking in this way. If, for example, the hand gripping the sled reaches the area of the slitting tool due to carelessness, severe injuries, in particular in the area of the hand, can result.
  • the handle arrangement does not ensure that the device is securely pressed onto the surface of the masonry during the production of the slots.
  • the handle having the locking switch has a handle area, the longitudinal axis of which, in the working position of the device, runs parallel to the disk plane of the slitting tool and outwardly inclined towards the slide plane.
  • the contact pressure exerted by the hand is only very unfavorably transferred to the handle in this way, so that fatigue appears quickly.
  • the result of this are slots with different depths.
  • the invention has for its object to provide a wall slot device with which slots in masonry can be produced quickly, accurately, safely and without fatigue.
  • both handles have an essentially cylindrical handle area, the longitudinal axes of the handle areas being essentially perpendicular to the disk plane of the slotting tool and parallel to one another, and in that the electrical switch is arranged in the first handle.
  • the contact pressure generated by the operator's hands can be better transmitted to the device.
  • the fingers of both hands required to actuate the locking switch and the electric switch are essentially freely movable when pressing the device, since the contact pressure can mainly be released from the palms of the hands without the hands slipping off the grip areas.
  • the length of the grip areas of the handles having the locking switch and the electrical switch preferably corresponds to 0.5 to 1 times the width of the housing measured at right angles to the plane of the slotted tool.
  • the locking switch and the electrical switch are arranged in the handles, the locking switch and the electrical switch expediently having strip-shaped keys which are arranged parallel to the longitudinal extent of the grip areas on the grip areas.
  • the keys are preferably arranged in the middle of the grip areas. This special design and arrangement of the keys enables right-handed and left-handed people to operate the device equally.
  • the length of the buttons advantageously corresponds to 0.5 to 1 times the length of the handle area so that the locking switch and the electric switch can also be operated when the handles are eccentrically encompassed.
  • the grip areas are usually gripped from the outside, so that the fingers of both hands rest under the underside of the grip areas on the inside of the grip areas.
  • a suitable actuation of the locking switch and the electric switch with the aid of the fingers can be achieved if the buttons of the locking switch and the electric switch are preferably arranged on mutually facing sides of the handle areas.
  • buttons of the locking switch and the electric switch can be actuated with little effort if the directions of action of the buttons of the locking switch and the electric switch are expediently inclined in the direction of the slide.
  • buttons of both switches are arranged on the handle areas of both handles in such a way that the directions of action of the buttons advantageously include an angle of 80 ° to 180 °.
  • the wall slot device shown in FIGS. 1, 2 and 3 is composed of a housing 1 having the width B, a drive unit 2 connected to the housing 1 for a slot tool 4 consisting of two disks 25 arranged next to one another and a slide 3.
  • the housing 1 can be pivoted parallel to the disk plane of the slot tool 4 about a rotary bearing 6 arranged in a first end region of the housing against the force of a spring element 7.
  • the housing 1 Both in the first end region, which is connected to the slide 3 via the rotary bearing 6, and in a second end region, the housing 1 has a handle 9, 10, which projects from the housing 1 Handle areas 12, 13 of the handles 9, 10.
  • an electric switch 5 is arranged, which sets the drive unit 2 in motion when actuated.
  • a locking switch 11 is arranged which, when actuated, displaces a locking element 8 which serves to limit the pivoting movement between the housing 1 and the slide 3.
  • the locking switch 11 and the electric switch 5 are each provided with a strip-shaped button 14, 15, which radially protrude beyond the grip areas 12, 13 and extend essentially over the entire length L3, L4 of the grip areas 12, 13.
  • the length of the key 14 is denoted by L1 and the length of the key 15 is denoted by L2.
  • the buttons 14, 15 of both switches are arranged on mutually facing sides of the grip areas 12, 13 inclined in the direction of the slide 3, so that the directions of action of the buttons 14, 15 enclose an angle W of 110 °.
  • a backdrop is arranged between the electrical switch 5 and its assigned button 15, against which the button 15 must first be offset by an amount parallel to the longitudinal extent of the grip area 13 before at least one End area of the button 15 in the radial direction, based on the longitudinal axis of the grip area 13, is displaceable.
  • the locking element 8 which can be actuated by the locking switch 11 is in the locked position and is supported on a locking rail 17 which projects from the slide 3.
  • a depth stop 18 is arranged on this locking rail 17 and can be adjusted in stages along the locking rail 17.
  • the depth stop 18 can be set to a desired slot depth T with the aid of an adjustment scale 19 also protruding from the slide 3.
  • a motor shaft, not shown, of the drive unit 2 arranged in the housing 1 extends in the longitudinal direction of the housing 1.
  • a gear, not shown, connected to the drive unit has an output shaft 24 which extends at right angles to the longitudinal direction of the housing 1 and on which the slotted tool 4 composed of two disks 25 is fastened.
  • a suction nozzle 20 On the top of the housing 1, between the two handles 9, 10, a suction nozzle 20 is attached, to which a suction hose 21 connects.
  • the suction hose 21 is provided with holding elements 22, with the aid of which an electrical cable 16 protruding between the handles 9, 10 from the housing 1 can be clipped onto the suction hose 21.
  • the slide 3 of the device has an essentially rectangular outer contour.
  • rollers 23 are arranged, which are intended to better move the carriage 3 on a surface U to be machined.
  • the rollers 23 are arranged in such a way that the carriage 3 or the entire device can only be moved in the directions running parallel to the longitudinal extent of the device. So that a rotation of the rollers 23 is ensured even when a long side of the slide 3 is guided along a wall (not shown) or a longitudinal stop, the rollers 23 are arranged set back relative to the long sides of the slide 3.
  • the pivot bearing 6 is designed as an axis, the central axis of which runs essentially coaxially with the longitudinal axes of the rollers 23.
  • the housing 1 also has a rectangular outer contour which essentially corresponds to the outer contour of the slide 3.
