Definitions

  • the present invention relates to a tool for working wood by removing material comprising a body provided with gripping means and containing an electric motor driving a rotor carrying means for removing material projecting, in rotation, through a opening under said body.
  • Electric planes are known for planing flat surfaces and provided with a central handle extending in the direction of movement of the planer.
  • a central handle extending in the direction of movement of the planer.
  • the tool used is still the very old bastringue.
  • known electric sanders use either a continuously rotating tape or a vibrating plate on which a canvas or abrasive paper is fixed. These sanders are also designed exclusively for sanding flat surfaces.
  • the object of the present invention is to produce an electric tool, which can be equipped with a planer or a sander, making it possible to work both concave or convex surfaces as well as flat surfaces, and consequently capable of constituting, in particular, an electric bastringue.
  • the tool according to the invention is characterized in that the body is provided with two removable guide parts, the parallel opposite edges of which determine said opening, at least one of these guide parts being adjustable, and by the fact that the means of gripping are constituted by two handles extending on each side of the body, in a substantially rectilinear manner and parallel to the axis of the rotor, along an axis passing inside the rotor.
  • the removable guide parts can be parts having convex or concave cylindrical surfaces or parallel flat surfaces, these guide parts being interchangeable. If the rotor is fitted with blades, one obtains, depending on the guide parts used, either a bastringue or an electric planer for flat surfaces. This rotor can however be replaced by a rotor intended to receive an abrasive sheet or strip, which makes the tool a sander.
  • the tool shown comprises a body 1 of light alloy molded comprising in its upper part a cylindrical housing 2 (FIG. 4) for an electric motor, not shown, communicating with the outside by ventilation openings 3.
  • the lower part of the body 1 also has a cylindrical housing 4, widely open in its lower part and housing a rotor 5 provided with two blades 6 and 7 and constituting a plane.
  • the body 1 is provided laterally with a plate 8 on which are mounted members for transmitting the rotation of the motor to the rotor 5. These transmission members are protected by a cover 9.
  • On the body 1 are also fixed two pieces of guide 10 and 11, which will subsequently be simply designated by guides 10 and 11.
  • These guides 10 and 11 have two parallel lower edges 12 and 13 which determine an opening 14 by which the blades 6 and 7 of the rotor 5 can attack the surface to be planed.
  • the body 1 is further provided with two handles 15 and 16 fixed laterally on each side of the body 1 and directed along an axis coinciding with the axis of the rotor 5.
  • the axis of the handles 15 and 16 could however also be located at- above or below the axis of the rotor 5. In all cases, the axis of the handles will pass through the rotor 5.
  • the direction of rotation of the rotor 5 and the direction of movement of the planer are indicated by arrows in the drawing.
  • the handle 15 is therefore intended for the right hand, while the handle 16 is intended for the left hand.
  • the handle 15 is provided with a control switch 17.
  • the power cord 18 is connected to the end of the handle 15 and it is therefore completely outside the path of the tool, which reduces the risks cutting the cord by the rotor blades. This cord 18 could be plugged into the handle 15.
  • the body 1 has a discharge opening 19 extending practically over the entire length of the rotor, above and behind the latter, and relatively wide. This discharge orifice 19 therefore ensures excellent chip evacuation.
  • the evacuation duct also widens outwards, by a curved surface 20 (FIG. 4), which contributes to eliminating the risk of blockage.
  • the guide 11 is fixed to the body 1 by means of a screw 21 and it is further guided by two pins 22 and 23 (FIG. 3) respectively engaging, with clearance, in holes 24 and 25 of the guide 11.
  • an elas element tick 27 for example of rubber.
  • the guide 11 has a flange 28 which comes to bear against the face 26 of the body.
  • the guide 11 has a stop 29 (FIG. 4) intended to limit the compression of the elastic element 27 by abutting against the body 1, and consequently to limit the tilting of the guide 11 around its rim d 'support 28.
  • the rear guide 10 is fixed in the same way as the guide 11, by means of a screw 31 and pins 32 and 33, but without the interposition of elastic elements.
  • the planar guides 10 and 11 can be replaced by guides of different shapes, for example convex guides such as the guides 34 and 35 shown in FIGS. 5 and 6. These guides have a cylindrical convex underside 36, respectively 37, approximately located on the same cylindrical envelope, this being true for a particular position of the anterior guide 34, adjustable like the guide 11 and having for this purpose a similar rim 28 ′.
  • the rear guide 35 is fixed.
  • the tool constitutes a bastringue making it possible to plane concave surfaces.
  • the depth of the pass is adjusted by means of the screw 21.
  • the guides 34 and 35 can be replaced by guides whose convexity is of a different radius to adapt the tool to the concavity of the area to plan.
  • FIG. 6 represents the tool, used in bastringue, provided with guides 38 and 39 having a radius of curvature substantially smaller than that of the guides 34 and 35.
  • the guide 38 is shown in the position for maximum adjustment of the pass, its abutment 29 ⁇ being in abutment against the body 1 of the tool.
  • the position of the handles 15 and 16 in the extension of the axis of the rotor 5 or close to this axis is particularly advantageous.
  • the guides can be exchanged for guides of different shapes, guides can be mounted on the tool having all shapes usable for woodworking.
  • the guides may have concave faces for working convex rounding.
  • the elastic element 27 could be replaced by springs. It could also be replaced by screws positioning the front guide rigidly.
  • the blade rotor 5 can be replaced by a rotor provided with a radial slot for fixing an abrasive strip or sheet and coated with an elastic coating.
  • the tool thus equipped therefore constitutes a sander. With the same tool it is therefore possible to plan a concave surface, then to sand this surface.
