Definitions

  • portable power planers comprise a motor driven rotary cutter head having one or more cutting blade assemblies disposed thereon for performing a planing operation on the surface of a workpiece as the cutter head rotates.
  • the bottom surface of the tool consists of a fixed shoe located rearwardly of the cutter head and an adjustable shoe disposed forwardly of the cutter head. As the front shoe is adjusted upwardly or downwardly, the cutting depth of the cutting blade of the planer is adjusted accordingly.
  • the adjustable front shoe of a portable power planer typically includes an integral stem or sleeve that is threaded either directly to an adjustment cap disposed atop the front end of the housing or to a threaded shaft or bolt that is in turn fastened at its other end to the adjustment cap for rotation therewith.
  • a powerful compression spring is interposed about the sleeve between the shoe and the housing to maintain the elevation of the adjustable shoe in the position set by the operator.
  • the compression spring is held in compression between the adjustable shoe and the housing and must be of sufficient strength to resist the natural tendency of the operator to bear down upon the planer when performing a planing operation, and yet be sufficiently compressible to permit convenient upward adjustment of the adjustable front shoe.
  • the operator can overcome the thrust force of the compression spring and dislodge the adjustable shoe from its preset position, thereby causing an undesired variation in the depth of cut.
  • an adjustable shoe In another portable manually operated power planer (GB-A-248 253) an adjustable shoe carries two screw-threaded bolts which extend through a bore in the wall of the housing of the planer and are mounted movable therein.
  • the free ends of the bolts which are formed with screw threads have fixed each a ring against which a spring bears whereas the other end of the spring is received in the bore.
  • These springs serve to hold the adjustable shoe against the housing.
  • a set screw is provided which is screwed into the housing and has at its free end a knob whilst the other end abuts against the adjustable shoe. Adjustment of the shoe is effected by turning the knob of the set screw so that the shoe is moved against the influence of the springs away from the housing so that the depth of the cut of the planer is adjusted.
  • the prior planer requires two screw-threaded bolts with a spring for each bolt for guiding the adjustable shoe as well as a set screw for adjusting the cut depth of the planer.
  • CH-A-297 502 It is also known (CH-A-297 502) to provide a portable power planer with positioning means which include a rod affixed at one end to an adjustable shoe and threadedly engaged to a rotatable positioning nut which abuts a bracket mounted on the housing of the planer.
  • the adjustable shoe serves to obtain a stationary arrangement of the planer whereas the depth of cut is adjusted by means of screw-threaded bolts which permit adjustment of the positions of rollers which come into engagement with the workpiece and are located in front of and behind the motor-driven cutter head.
  • the invention relates to a depth of cut adjustment mechanism for a portable power planer including an adjustable shoe and positioning means interfacing said shoe with the housing of the planer for controlling the elevation position of said shoe to set the depth of cut of the planer, with a spring for exerting a tension force to take up the inherent tolerance play of the interface of said shoe and said housing to firmly hold said shoe in the elevation position by said positioning means
  • said positioning means includes a substantially S-shaped rod affixed at one end of said shoe and threadedly engaged at its other end to a positioning nut rotatably mounted in a race formed in said housing but fixed in elevation with respect thereto and that the spring is a tension spring that is connected at one end to said shoe adjacent to said rod and at its other end to said housing.
  • the preferred embodiment of the present invention includes means for calibrating the elevation adjustment mechanism so that when the scale provided on the adjustment cap reads zero, the adjustable shoe is set for zero cutting depth.
  • a positive park position is also provided which when engaged sets the adjustable shoe below zero elevation so that the cutting blades will not mar the surface upon which the tool is placed.
  • a portable power planer 20 of the type of which the present invention relates is conventional in overall layout comprising a clamshell-type housing 22 incorporating a motor-driven cutter head 24 having mounted thereon a pair of cutting blade assemblies 26 for performing a planing operation of the surface of a workpiece as the cutter head 24 rotates.
  • the bottom surface of the tool 20 comprises a fixed shoe 28 located rearwardly of the cutter head 24 and an adjustable front shoe 30 disposed forwardly of the cutter head 24. Elevational adjustment of the front shoe 30 causes a corresponding adjustment of the depth of cut of the cutting blades 26.
  • the adjustable front shoe 30 includes an integral socket-like projection 32 extending upwardly from the base thereof.
  • Projection 32 also contains diametrically opposed, radially outwardly extending integral flanges 34 which are adapted to be received within a pair of slots 36 ( Figure 3) formed by boss members 38 in housing 22.
  • the left-hand housing member shown in Figure 3 is illustrative of the complementary-shaped right-hand housing member.
  • the flanges 34 serve to laterally stabilize the adjustable front shoe 30 as well as prevent the front shoe 30 from rotating relative to the housing 22.
  • An S-shaped rod 40 is fixedly mounted at one end in the socket-like projection 32 of adjustable front shoe 30.
  • An elevation positioning nut 42 is threadedly engaged to the upper end of rod 40.
  • Elevation positioning nut 42 is rotatably mounted within a race 44 formed in housing 22 by the joinder of the right-hand and left-hand halves.
  • the race 44 permits rotation of elevation positioning nut 42 relative to the housing 22 but prevents elevational movement with respect thereto.
  • adjustable front shoe 30 has a ridge 50 formed along its rearward end which extends upwardly at an acute angle from the base of the shoe 30.
  • Ridge 50 together with the rearward most tangential surface of socket-like projection 32 form a slot 52 adjacent the back portion of projection 32 which is adapted to engage a downwardly projecting wall 54 formed in the housing 22.
  • Ridge 50 coacts with downwardly projecting wall 54 to prevent rotation of adjustable front shoe 30 with respect to housing 22 and also to guide the elevational movement of front shoe 30.
  • sufficient clearance is provided between downwardly projecting wall 54 and the base of front shoe 30 to permit adequate elevational adjustment in the position of front shoe 30.
  • a control knob 46 is fastened to elevation adjustment nut 42 so as to be exposed atop the forward end of housing 22.
  • Control knob 46 is secured to adjustment nut 42 by means of a plurality of flexible fingers 48 which are adapted to grasp the undersurface of a circular ridge 56 formed around the nut 42.
  • Control knob 46 is keyed to elevation adjustment nut 42 so as to rotate therewith by the mutual engagement of corresponding sets of fine teeth 58 and 60 formed on the inside surfaces of flexible fingers 48 of control knob 46 and the outer radial surface of ridge 56 of nut 42, respectively.
  • the tooth configuration shown in detail in Figures 7 and 10, is fine enough to permit precise angular positioning of control knob 46 relative to elevational adjustment nut 42 while at the same time providing a tight connection therebetween.
  • a scale 64 is provided on the top surface of control knob 46 which is referenced to an arrow 62 ( Figure 12) located on the outer surface of housing 22.
  • the scale 64 on control knob 46 is calibrated in the following manner. Initially, with the control knob 46 removed, the elevation adjustment nut 42 is rotated until the adjustable front shoe 30 is located in the zero depth of cut position. The control knob 46 is then properly oriented and fastened onto elevation adjustment nut 42 in the manner described so that the reference arrow 62 on housing 22 is aligned with the zero indication on the scale. Thereafter, manual rotation of control knob 46 will cause rotation of elevation adjustment nut 42 and a corresponding variation in the elevational position of front shoe 30, which will be reflected in the reading on the control knob scale 64.
  • control knob 46 is provided with a downwardly projecting tab 66 which is adapted to abut a stop 68 located on the left-hand portion of housing 22. Engagement of the stop 68 by control knob 46 in the counterclockwise direction of rotation provides a positive "park" position wherein the adjustable front shoe is positioned below the zero depth of cut position to prevent the cutting blades 26 from marring the surface upon which the tool is placed. In the preferred embodiment herein, engagement of the stop 68 by the control knob 46 in the clockwise direction of rotation corresponds to the maximum cutting depth of 0.5 millimeters.
  • a tension spring 70 is connected between the socket portion 32 of adjustable front shoe 30 and the front of housing 22.
  • the spring 70 is maintained under tension and serves to cancel out any tolerance play which may exist between the adjustable front shoe 30 and the housing 22, thus avoiding a disconcerting wobble movement in the front shoe.
  • tension spring 70 is disposed so that its axis is substantially parallel with the axes of S-shaped rod 40 at its upper and lower ends to prevent binding of adjustment nut 42. It is also preferred that spring 70 be mounted to the socket portion 32 of adjustable shoe 30 closely adjacent rod 40 to minimize the moment created by the slightly offset tension force of the spring 70 relative to the axes of rod 40.
  • the present tension spring 70 works with the operator as he bears down upon the tool during operation.
  • the adjustable front shoe 30 appear to "float" as in the case of a compression spring when the force of the spring is balanced by the downward force exerted by the operator.
  • the present tension spring 70 works with the natural tendencies of the operator, the adjustable front shoe 30 is always maintained in the desired elevational position.
  • the use of the substantially smaller tension spring 70 in combination with the S-shaped rod 40 significantly reduces the space required within the tool housing 22 when compared to conventional compression spring designs.
  • a significant reduction in manufacturing cost is also realized.
