  • the present invention relates to power tools and more specifically to a clamp arrangement for releasably securing an accessory to an oscillating handheld power tool.
  • Handheld power tools are provided in many examples for performing a wide range of tasks.
  • some power hand tools can include an output member that is driven by a motor and that couples with an accessory to perform a working operation onto a work piece.
  • some power tools can provide various configurations for attaching cutting accessories, grinding accessories, sanding accessories and the like.
  • Some power tools are configured as oscillating tools that are operable to transmit an oscillating motion onto the accessory.
  • a user may want to exchange one accessory for another accessory. For example, a user may want to exchange one grinding accessory with another grinding accessory or one sanding platen with another sanding platen. Alternatively, a user may wish to replace a cutting accessory with another cutting accessory. It is also contemplated that a user may want to replace a given accessory dedicated to one task (such as sanding) with another accessory dedicated toward another task (such as cutting for example).
  • many power hand tools require the use of a secondary tool in order to swap accessories. For example, many power hand tools require the use of a hand screw driver that can be used to retract a fastener that may lock the accessory to the output member of the power hand tool. In other examples, a wrench or other hand tool may be required to remove or unlock a given accessory from the power hand tool and subsequently lock another accessory back to the power hand tool.

It will be appreciated that the operator is not required to release the button 872 to lock the clamp member body 824 at a displaced position from the second clamp member 838 while inserting the accessory 14g.
  • a clamp arrangement constructed in accordance to another example of the present disclosure is shown and generally identified at reference numeral 910.
  • the clamp arrangement 910 is shown generally associated with a first output member 416a ( Fig. 19 ) of the first power tool 412a ( Fig. 6 ).
  • the clamp assembly 910 includes a clamp assembly 914 that is configured to be selectively coupled to the first or second power tools 412a and 412b.
  • the clamp assembly 914 may incorporate additional or alternative geometry for mating with other power tools such as those described herein.
  • the clamp assembly 914 is configured to selectively and alternatively retain various accessories such as the seventh accessory 14g ( Figs. 19-20 ).
  • the clamp assembly 914 is configured to be suitably coupled with either of the output member 416a provided on the first power tool 412a or the output member 416b provided on the second power tool 412b.
  • the clamp assembly 914 generally includes an attachment plate 920 having a first clamp member 922 movably coupled thereto.
  • the first clamp member 922 can generally include a first clamp member body 924 that defines a through bore 926 ( Fig. 18 ), an inset 928, a blind bore 930, and a radial channel 932.
  • the first clamp member body 924 includes an annular flange 934. As will be described herein, the annular flange 934 can facilitate a gripping of the user onto the clamp member body 924.
  • a fastener 500' can include threads 504' that threadably mate with corresponding threads defined in the output member 416a. The fastener 500' can therefore capture the clamp assembly 914 to the identified power tool.
  • the first clamp member 922 is configured to translate relative to a second clamp member 938 as will become appreciated from the following discussion.
  • the second clamp member 938 can include a second clamp member body 940.
  • the second clamp body 940 can be generally formed similar to the second clamp body 460 described above and will not be repeated.
  • the attachment plate 920 can generally include an attachment plate body 944 that provides an attachment plate mating detail 946.
  • the attachment plate mating detail 946 can generally comprise a raised annular rim 948 having a central recess 950 and a plurality of receiving portions 952 formed thereon. In the example shown, the raised rim 948 incorporates twelve receiving portions 952 in the form of oval recesses 954.
  • the oval recesses 954 can be configured to selectively receive the protrusions 422a provided on the first mating geometry 420a of the first power tool 412a. Again, the oval recesses 954 can cooperatively mate with protrusions 422a having various diameters.
  • the central recess 950 can be a keyed sidewall 958 defined into the attachment plate body 944.
  • the keyed sidewall 958 can generally be in the form of a twelve point star.
  • the attachment plate 920 further comprises a stem 960 extending therefrom.
  • the stem 960 is shown separately formed from the attachment plate 920 and to the second clamp member 938. However, it is contemplated that the stem 960 can be integrally formed with the attachment plate 920.
  • the stem 960 defines a longitudinal axis 962.
  • a first series of threads 964 can be formed around the stem 960.
  • the first series of threads 964 can collectively define a first gripping detail 966.
  • the first gripping detail 966 can therefore be associated with, or fixed relative to, the second clamp member 938.
  • a first biasing member 970 can be located generally around the stem 960 and configured for engaging the clamp member body 924 at the inset 928 on one end and the attachment plate 920 on an opposite end.
  • the first biasing member 970 can provide a biasing force onto the clamp member body 924 and the direction of the second clamp member 938 or downwardly along the longitudinal axis 962.
  • a button 972 defines a button axis 973 and can be at least partially received into the blind bore 930 of the clamp member body 924 against a bias of a second biasing member 974.
  • the button 972 includes a second series of threads 978 that collectively define a second gripping detail 980.
  • the first series of threads 964 can threadably mate with the second series of threads 978 for locating the button 972 at the desired location along the stem 960.
  • the second biasing member 974 can provide a bias against the button 972 forcing the button 972 in a direction rightward as viewed in Fig. 19 along the button axis 973.
  • the second gripping detail 980 of the second series of threads 978 are caused to mate and therefore cooperatively lock with the first gripping detail 966 of the first series of threads 964 on the stem 960.
  • the button 972 can be translated in a direction leftward (as viewed in Fig. 18 ) along the button axis 973 against the bias of the second biasing member 974.
  • the first series of threads 964 and the second series of threads 978 are caused to disengage whereby the operator can subsequently translate the clamp member body 924 in a direction along the axis 962 of the stem 960.
  • the operator can release the button 972 causing the respective first and second series of threads 964 and 978 to lock.
  • an operator may rotate the first clamp member body 924 in a direction generally around the longitudinal axis 962 causing the first clamp member 922 to threadably advance along the first series of threads 964 to a desired position.
  • the user can place the desired accessory between the first and second clamp members 922 and 938.
  • the user can again depress the button 972 allowing the first biasing member 970 to direct the clamp member body 924 in a direction toward the accessory 14g until the accessory 14g is suitably clamped between the first and second clamp members 822 and 838.
  • a user may alternatively rotate the first clamp member body 924 to move the first clamp member 922 into a position that suitably clamps the accessory 14g between the first and second clamp members 922 and 938, respectively.
  • a user can optionally further rotate the clamp member body 924 in a direction around the axis 962 causing the first and second series of thread portions 964 and 978 to engage whereby the user can further translate the first clamp member body 924 toward the second clamp member 938.
  • Such a configuration may be particularly advantageous for aggressive applications where it may be desired to provide an increased clamping force onto an accessory.
  • the clamp arrangement 910 is shown operatively clamping an accessory 14b in the form of a sanding platen.
  • the accessory 14b can be suitably clamped between the first and second clamp members 922 and 938.
  • the first clamp member body 924 can be rotated around the stem 960 to provide a tighter clamping force onto the accessory 14b.
