(19) Referring initially to FIGS. 1-3 and 7-9, there can be provided a miter device 100 having a rectangular planar base 102, which can have a top side 104, an opposing bottom side 106, a front end 108, an opposing back end 110, and two corresponding side ends 112. The rectangular planar base 102 can also have a rectangular peninsula section 114 extending from a central portion 116 of the front end 108 of the planar base 102. The rectangular planar base 102 can also have a rectangular recess 118 indented along a corresponding central portion 120 of the back end 110 of the planar base 102. The front end 108 and the back end 110 of the planar base 102 can have a lateral length 122 and the side ends 112 can each have a longitudinal length 124.
(20) Still referring to FIGS. 1-3 and 7-9, the rectangular peninsula section 114 and the rectangular recess 118 can each have a lateral length which corresponds to the central portion 116 of the front end 108 and the central portion 120 of the back end 110, respectively. The rectangular peninsula section 114 can have a longitudinal length 126. The rectangular recess 118 can have a longitudinal indentation length 128 and a lateral length which corresponds in placement to the central portion of the rear 120 and in length to the lateral length of the peninsula section 114, i.e., the central portion 116 of the front end 108. The rectangular planar base 102 can contain opening therein.
(21) Referring first to FIGS. 3, 9 and 10, the rectangular planar base 102 can also be comprises of two halves 132 and 134 which can be connected by a portion 136 of the peninsular section 114, (now referring to FIGS. 1, 2 and 8) the entire front end fence 138 and a portion 140 of the rear end fence 142. The rear end fence 142 can have a perpendicular length 144. The front end fence 138 can have a perpendicular length 146.
(22) Referring now to FIGS. 1, 2 and 8-10, the miter device 100 can also have two angled guide rails 148 which can be releasably fixed to the top side 104 of the rectangular planar base 102. Each of the angled guide rails 148 extends in a first angular direction 150 starting from the central portion 116 of the front end 108 towards a different one of the corresponding side ends 112. Then each of the two angled guide rails 148 turns to extend in a second angular direction 152 which can be directly perpendicular to the side ends 112.
(23) Referring still to FIGS. 1, 2 and 8-10, the two angular guide rails 148 can be made up of a planar guide rail support section 154 which lies on the top side 104 of the planar base 102 and a corresponding perpendicular guide rail fence section 156. It will be understood herein that reference to first direction 150 can encompass the entire length of the planar guide rail support section 154 and perpendicular guide rail fence section 156 before the turn to the second direction 152. Likewise, will be understood herein that reference to second direction 152 can encompass the entire length of the planar guide rail support section 154 and perpendicular guide rail fence section 156 after the turn from the first direction 150.
(24) In one embodiment, the front end of the rectangular base corresponds to the line 122 along the front end 108 of the base 102. In addition, the central portion of the front end can correspond to the line 116, which can also be defined as the base of the peninsula 116. The parallel side edges of the peninsula correspond to the longitudinal length of the peninsula 126. In one embodiment the planar guide rail support section 154 can be angled at its ends 158
(25) In one embodiment, the planar guide rail support section 154 can extend the entire length of the first angular direction 150 starting from the central portion 116 of the front end 108, as can the perpendicular guide rail fence section 156 and then extend at the turn to extend in the second angular direction 152 perpendicular to the side ends 112. The angled end 158 of the planar guide rail support section 154 at the end of the first angular direction 150 can be wide enough to also support and correspond to the above described percentages of the length of the perpendicular guide rail section 156 that runs in the second angled direction 152. The planar guide rail support section 154 and the perpendicular guide rail fence section 156 can each have the same width.
(26) In another embodiment, the planar guide rail support section 154 and the perpendicular guide rail section 156 can meet at a perpendicular joint 162 and can also be connected to each other along the joint 162 by applicable means such as a weld, solder or the like. Referring now to FIGS. 1 and 8-10, the planar guide rail support sections 154 can be releasably fixed to the top side 104 of the rectangular planar base 102 by any fixation means 164 as described herein. Referring to FIGS. 13-15, the fixation means 264 can be turn key handles 264.
(27) Referring to FIGS. 1 and 8-10, the rectangular planar base 102 can have a series of fixation element holes 166 which can permit the planar guide rail support sections 154 and their connected perpendicular guide rail sections 156 to be repositioned to a different angular position on the base 102.
(28) Referring now to FIGS. 13-15, the reference numbers used in FIGS. 1-12 are equivalent to those herein with the exception that the one hundred series of reference numerals are re-stated in a two hundred series of reference numerals, e.g., 104 in FIG. 1 becomes 204 in FIGS. 13-15 and the like. In one embodiment, the planar guide rail support sections 254 and their connected perpendicular guide rail sections 256 can be released from their fixation to the planar base 204 and rotated by moving the turn key handles 264 attached to a screw 268 in a pre-existing arc 270 in the aforementioned angles. The planar guide rails 254 can have an opening 272 along the first angled direction 250 such that the specific angle of rotation of the unit 254/256 in the arc 270 (shown by the arrows in FIG. 15) can be gauged by reference to a pre-existing measurement guide 274 of the degrees moved which can be on the top side 204 of the base 202 such that it can be visible through the opening 272. The preexisting arc 270 can be made up of segments 276 which can be straight lines which can be each joined to the adjoining segment 276 to provide for the overall segmented arc 270. The presence of the round screw 268 in the straight segments 276 prevents the screw 268 from easily moving along the arc 270 without first reducing pressure thereon by loosening the turn key 264.
(29) Referring now to FIGS. 1-5 and 8-10, the miter 100 can also have two parallel longitudinal track guides 178 each having a track opening 180 running a longitudinal length 182 of the track guide 178. The track guides 178 can be positioned along the bottom side 106 of the base 102 and extend from between the back end 110 of the base 102 to a position beyond the front end 108 of the base 102, and which track guides 178 can be each adjustably secured to the base 102 in an identical position along the track openings 180. Preferably each of the longitudinal track guides 178 can be each adjustably secured to the planar base 102 by turn key devices 264. The track guides 178 extend the above noted distances beyond the front end 108 of the planar base 102, preferably outside the peninsular section 114 of the planar base 102 on the front end 108 of the planar base 102.
(30) Referring now more specifically to FIGS. 4 and 5, the longitudinal track guides 178 can be secured to the planar base 102 by rectangular clamps 184. The rectangular clamps 184 can be rectangular housings having a fixation portion 186 and a clamping portion 188. The fixation portion 186 of the clamp 184 can be thicker than the clamping portion 188. The fixation portion 186 can accommodate a fixation element 190 such as a screw 190, which is inverted, the head 192 of the screw 190 being located in the track opening 180 of the track guides 178, and the post portion 194 of the scree 190 can extend through the fixation portion 186 through a hole 196 therein, which can be capped with the turn key 164. The head 192 of the screw 190 and the other components of the clamp 184 can be dragged to a suitable position in the track opening 180 of the track guides 178, such that the clamping portion 188 of the clamps 184 is over the top side 108 of the planar base 102, which track guides 178 in turn can be located in tracks of a table saw (not shown), and the tightening of the turn key 164 above the fixation portion 186 can cause the clamping portion 188 to likewise tighten and clamp the track guide 178 to the planar base 102.
(31) Referring now to FIGS. 1-3 and 6-10 the miter device 100 can have a safety stop 198 inserted into an end 199 of the track opening 180 of the track guides 178 positioned beyond the front end 108 of the base 102. The safety stop 198 can be affixed to the track opening 180 by a turn key 164 component. In one embodiment a safety stop 198 can be inserted into both ends 199 of the track openings 180 in the two longitudinal track guides 178. Referring more specifically to FIGS. 6 and 7, the safety stop 198 can have stop portion 147 and a post portion 149 which in turn can have a raised step 151 there along. The stop portion 147 can be affixed to the post portion 149 by a fixation element 190, which can be an Allen head bolt 190 and a pin 153.
(32) Referring now to FIGS. 1, 2 and 8 the miter device 100 can have front end fence 138 which can be perpendicular to and extends along a front end 139, preferably an entire front end 139 of the rectangular peninsula section 114 of the base 102. The miter device 100 can also have a handle 141 protruding from a front surface 143 of the front end fence 138, which can be supported by posts 145.
(33) Referring now to FIGS. 1, 2 and 8 the miter device 100 can have rear end fence 142, which can be perpendicular to and extends along the central part 120 of the back end 110, preferably along the entire central part 120 of the back end 110.
(34) Referring to FIGS. 1, 3 and 8-10 the base 102 can have a blade track 155 extending from the peninsular section 114 through the indented central part 120 of the back side 110 and a portion of the rear fence 142.
(35) Referring to FIGS. 8, 9 and 11, the miter device 100 can be used to cut a board 155 into two parts 157 directly across the grain, i.e., a cross cut by a blade 159 of a table saw (not shown) by placing the board 155 flush along the perpendicular guide rail fence section 156 of the second direction 152 and pushing the handle 141 in the direction of the blade 159. Alternatively, referring to FIGS. 10, 12 and 15 the miter device 100 can be used to cut board 155 into two parts 157 at an angle, i.e., an angled cross cut by the blade 159 by placing the board 155 flush along side one of the perpendicular guide rail fence sections 156 of the first direction 150 and pushing the handle 141 in the direction of the blade 159.
(36) Since many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Furthermore, it is understood that any of the features presented in the embodiments may be integrated into any of the other embodiments unless explicitly stated otherwise. The scope of the invention should be determined by the appended claims and their legal equivalents.
