  • Padding 14 is also used in this embodiment
  • the jack 50 might be replaced with other adjusting mechanisms
  • One example would be to have an adjusting bolt within the p ⁇ mary leg 4 which is rotated by a handle outside of the p ⁇ mary leg The length of adjusting bolt would rotate and would run parallel and within the p ⁇ mary leg length
  • the bracket could be mounted to an adjusting nut which was fitted onto this adjusting bolt A the bolt was turned, the height of the bracket would vary as the nut holding the bracket moved up and down the bolt
  • the bracket defines holes 18 through which a nail or screw may be d ⁇ ven to secure the cutting surface 1
  • the attachment surface shown in Figure 1 is the tailgate 11 of a truck Any similar surface would provide for a different embodiment, but is considered herein
  • Figure 7 shows the use of a receiver hitch 30 for receiving a receiver hitch beam 34 which in turn holds t-bar 36.
  • Support beams 31 extends upward from the t-bar 36, supported from the ground on one or more base plates 35.
  • the primary leg 4 then is attached to this support beam 31.
  • Extension beams 37 supported by base plates 35 may be provided to lengthen the sawhorse spread between two or more primary legs 4.

However, a lesser angle might be utilized and still accomplish the desired result.
  • This angle would preferably be for 30 degrees to 90 degrees.
  • a single bracket might be used instead of two as long as a space for cutting was formed, although this would result in a significantly different invention.
  • the ability to alter the spacing of the two cutting surfaces is a significant improvement.

Abstract

La présente invention concerne un chevalet de sciage montable sur une surface extérieure d'une voiture ou d'un camion. La surface de fixation est, de préférence, la porte arrière (11) d'un camion. On utilise, de préférence, au moins deux fixations (2) espacées d'une distance acceptable de façon à servir de chevalet de sciage. On peut faire varier la hauteur des fixations de manière à faire varier la distance au sol et à maintenir les surfaces de coupe supérieures de deux planches (1) par deux fixations parallèles séparées. Les planches se présentent, de préférence, sous un angle de 90 degrés par rapport à la face de la porte arrière. Les fixations, qui peuvent se monter sur la porte arrière, peuvent être amovibles, ou être intégrées à la porte arrière, soutenant ainsi une variété d'éléments distincts. Les fixations de l'invention peuvent également s'utiliser dans le cas d'autres surfaces.
