Definitions

  • the present invention relates to sanders and, more particularly, but not exclusively to random orbital sanders having multiple gripping members, including a spaced vertical handle.
  • Orbital sanders generally include a vertically orientated housing having a handle at an axial end of the housing. Thus, the handle is positioned above the orbital sanding element so that a workman applies force directly onto the orbital sanding element.
  • These handles have various types of designs in order to accommodate the workman's hand.
  • orbital sanders exist which include handles which extend from the housing substantially perpendicular to the orbital sander housing. These types of handles are in a horizontal orientation. Thus, during use, for a significant period of time, vibration can cause the user's hand to become fatigue. Accordingly, it is desirable to have an orbital sander which enables the user various gripping orientations to overcome the shortcoming of the prior art.
  • the present invention provides the art with a orbital sander that provides multiple gripping positions.
  • the orbital sander provides the user with a gripping surface spaced from the housing and substantially parallel to the housing.
  • the present invention provides the user with a gripping portion which surrounds the housing to provide a 360 degree handle for various orientations of the orbital sander.
  • the present invention provides the user with a palm grip having a gel portion to reduce vibration in the tool.
  • the present invention also enables the user to utilize both hands at various positions on the sander during operation.
  • an orbital sander comprises a housing with an overall axial orientation.
  • a motor is positioned within the housing.
  • An output is coupled with the motor to drive the orbital sanding element.
  • a power source is coupled with the motor.
  • An activation member is coupled with the motor and the power source. The activation member energizes and de-energizes the motor which, in turn, randomly rotates the output and sanding element.
  • a handle having an overall vertical orientation is spaced from the housing.
  • the housing ordinarily has a cylindrical portion and a truncated conical portion adjacent the cylindrical portion.
  • a gripping member is positioned at the intersection of the cylindrical portion and a truncated conical portion. The gripping member surrounds a portion of the housing.
  • the gripping member that surrounds the housing is formed from an elastomeric material providing comfort and feel for the user.
  • a gripping member maybe positioned on an end of the housing opposing the output. This gripping member may include a gel portion.
  • an orbital sander comprises a housing that has an overall axial orientation with two ends.
  • a motor is positioned within the housing.
  • An output coupled with the motor, is positioned at one of the ends of the housing to drive a sanding element.
  • a power source is coupled with the motor.
  • An activation member is coupled with the motor and the power source to energize and de-energize the motor which, in turn, drives the output and the sanding element.
  • a gripping member surrounds the housing.
  • the gripping member is positioned between the ends of the housing.
  • the gripping member is elastomeric to provide comfort and feel.
  • the gripping member is continuous 360 degrees around the housing.
  • the gripping member has an annular portion and an extending tail portion. The gripping member is positioned on a truncated conical portion of the housing.
  • an orbital sander comprises a housing having an axial orientation with a pair of ends.
  • a motor is positioned within the housing.
  • An output, coupled with the motor, is positioned at one of the end to drive a sanding element.
  • a power source is coupled with the motor.
  • An activation member is coupled with the motor and the power source to energize and de-energize the motor which, in turn, drives the output and the sanding element.
  • a plurality of gripping members are coupled with the housing. At least one gripping member is spaced from and positioned substantially parallel to the housing. The one gripping member is a handle. The others of the gripping members are on the housing. One of the gripping members surrounds a portion of the housing. One of the gripping members is positioned on the end of the housing opposing the output.
  • an orbital sander is illustrated and designated with the reference numeral 10.
  • the orbital sander includes a housing 12, a motor 14 positioned within the housing, an output 16 driven by the motor 14, and a platen or carrier 18 that is coupled to the output and oscillatingly driven.
  • a sanding element (not shown) is attached to the carrier 18. It should be understood that a polishing or other similar element, other than a sanding element, may be attached to carrier 18 and still be within the scope of the invention.
  • a dust collection system 20 is coupled with the housing 12. Also, a plurality of gripping members 22, 24, and 26 are coupled with the housing. An AC power cord 28 is coupled with the housing to provide power to the motor 14. An activation member 30 is coupled with the housing to energize and de-energize the motor 14, in turn, the output 16 which, in turn, rotates the carrier 18.
  • the housing 12 defines a central axis 13 and is normally used in a vertical orientation.
  • the housing 12 includes a cylindrical portion 32 and a truncated conical portion 34 positioned on axis 13.
  • the truncated conical portion 34 at its end includes a skirt 36.
  • the skirt 36 provides durability and protects the work surface while sanding.
  • a housing gripping member 22 is positioned at the intersection of the cylindrical portion 32 and the truncated conical portion 34.
  • the housing gripping member 22 includes an annular portion comprising a gripping surface 40 and a tail surface 42.
  • the gripping surface 40 surrounds the housing providing a 360 degree grip on the housing.
  • the gripping surface 40 is positioned at the other end of the truncated conical portion 34 wherein it intersects the cylindrical portion 32.
  • the tail surface 42 extends from the gripping surface 40 towards the skirt 36.
  • the housing gripping member 22 is an elastomeric member and may be over molded onto the housing 12. The elastomeric member provides a comfortable grip as well as increased feel to the user.
  • the other end of the housing 12 includes an upper gripping member 24.
  • the extending end of the cylindrical portion 32 has a teardrop shaped head 44 with the upper gripping member 24 positioned on top of the head 44.
  • the upper gripping member 24 has a teardrop shape and is formed from a gel material that forms an upper gripping surface.
  • the gel provides a top surface to absorb vibration of the sander to increase the comfort and/or duration of use by the user without fatigue.
  • axis 13 is located substantially centrally relative to the sander housing 12 throughout its entire extent. That is, axis 13 is centrally located with respect to all of upper gripping member 24, cylindrical portion 32 and conical portion 34. Further, as evident with reference to Figs. 3a and 3c, upper gripping member 24 defines an outer perimeter such that a downward projection of the outer perimeter defines a volume in which the housing 12 is substantially disposed within throughout its entire extent. In other words, the middle and lower parts of housing 12 do not extend outwardly of upper gripping member 24 for any substantial extent.
  • a handle gripping member 26 is spaced from the housing 12.
  • the handle gripping member 26 runs substantially parallel to the housing 12, and has a vertical orientation enabling the user to grip handle gripping member 26 to provide a different orientation for the user's hands.
  • the gripping orientations are illustrated in Figures 2a-2e. Also, the user may use two hands when gripping the handle gripping member 26 with another one of the gripping members 22 or 24.
  • the handle gripping member 26 is ordinarily formed with the housing 12 to provide a clamshell type of housing member.
  • the handle gripping member 26 includes gripping surface 46 and 48 on each of its sides.
  • the gripping surfaces 46 and 48 are similar to gripping surface 40, and made of an elastomeric material to provide comfort and feel to the user.
  • An open space is formed between gripping surfaces 46, 48 and housing 12 to allow for gripping of the gripping surfaces, with the user's hand oriented in a substantially vertical orientation, as explained below.
  • a user may grip the orbital sander at gripping member 22, 24 or 26. This allows the user to vary his hand positions to reduce fatigue during prolonged operation. Also, the user may use a plurality of the gripping members at one time. The user may use grips 22 and 26, 24 and 26, or 22 and 24 at one time to add increased control to the sander during operation.
  • the sander may be gripped with two hands utilizing various combinations of grips 22, 24 and 26, the preferred overall configurations and weight allow for the sander to be operated by the user with one hand by solely gripping upper grip 24.
  • the user's hand may extend substantially over the entire extent of the sander housing 12. In such a configuration, the user's palm rests substantially in a horizontal plane.
  • One advantage provided by this invention is that in addition to allowing for such overhanded gripping at the top of the sander, the user also can grip the sander with his second hand gripping spaced handle 26.
  • the user grips gripping surfaces 46 and 48 of handle 26 such that the palm of the second hand is disposed substantially vertically and therefore perpendicular to the palm of the first hand, to provide increased control during operation.
  • the weight of the orbital sander may be approximately 3.5 pounds.
  • the handle 26 need not be disposed precisely perpendicular to the gripping surface of upper grip 24, that is, it need not be disposed precisely vertical.
  • handle 26 and thus gripping surfaces 46 and 48 may be disposed substantially vertically at 103.46° to the horizontal gripping surface of upper grip 24, and thus at an angle of 13.46° to the vertical axis of housing 12. Prefereably, this angle may be varied within a range of 5°.
  • Figures 4a and 4b show a second embodiment of the invention, where the carrier 18, and consequently the sanding element (not shown), is rectangular shaped.
  • the orbital sander shown in Figures 4a and 4b is a 1 ⁇ 4 sheet sander, with the approximate dimension of the sander shown in millimeters.
