Fold together saw benches

Claim 1

A foldable sawhorse which comprises: (a) a first part having a first elongated crossbar, a first pair of substantially parallel spaced apart legs extending from the first crossbar and a first brace extending between the first pair of legs; (b) a second part having a second elongated crossbar, a second pair of substantially parallel spaced apart legs extending from the second crossbar and a second brace extending between the second pair of legs; (c) a pair of hinges spaced apart and connecting said first elongated crossbar to said second elongated crossbar to accommodate pivotal movement of said first and second parts between a first position in which the legs of said parts abut and are substantially parallel and a second position in which the cross bars of said parts abut so that the legs of said parts are in alignment with each other, the first and second positions can be used for storage; (d) means for selectively preventing pivotal movement of said first part relative to said second part so as to keep the first pair of legs in a spreading position relative to the second pair of legs to support a load on the crossbars, wherein said pivotal preventing means includes a pair of arms, each of said arms pivotly connected to and extending from one of the second pair of legs to one of the first pair of legs to be removeably connected thereto, further comprising means for adjusting the spreading position of the first pair of legs relative to the second pair of legs to change the overall height of said sawhorse, wherein said adjusting means includes: (e) each of the first pair of legs having a substantially vertical elongated side slot with a plurality of spaced apart oversized recesses therein and a pair of elongated double bevel wedges, each of which runs parallel on one side of the slot; (f) each of the second pair of legs having a substantially vertical elongated side slot with a plurality of spaced apart oversized recesses therein and a pair of elongated double bevel wedges, each of which runs parallel on one side of the last named slot; (g) each of said arms having a pair of double bevel cam surfaces on each end thereof so as to normally mate with the double bevel wedges; and (h) two pair of inwardly spring biased stop bolts each of which is disposed on one end of each of said arms to engage with one of said oversized recesses in one of said slots whereby when the first and second pair of legs are forced together said stop bolts will move up and out of the recesses allowing said arms to move for adjustment and when the first and second pair of legs are forced apart said stop bolts will move up and out of the recesses.
