Abstract
Abstract A pair of I legs are attached to a table top spaced apart longitudinally of the top and mounted for folding and unfolding movement longitudinally of the top. A stretcher bar is rotatably supported by, and comprises part of, a bracket assembly, which is mounted on the top between the leg mountings for folding and unfolding movement transversely of the table top. Projecting from the ends of the stretcher bar are pin means with heads adapted, in one angular position of the bar to enter slots in the legs respectively when the bracket assembly is in unfolded position and the unfolded legs are moved toward the ends of the bar, and to extend across the slots from within the legs when the bar is rotated to another angular position. A combination bar handle and bar locking means is provided.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
162 words
A folding trestle table comprising a top, a pair of legs spaced longitudinally of the top, and means supporting the legs from the top for folding and unfolding movement longitudinally of the top, a trestle bar assembly including a bracket supported on the under surface of the top for swinging movement transversely of the top, and a trestle bar member carRied by the bracket by means permitting the bar to be rotated around its longitudinal axis the trestle bar having pins projecting outwardly from its ends respectively, said pins having heads of different crosssectional dimensions, and the legs defining slots adapted when the parts are unfolded to receive the heads respectively when the heads are presented at the proper rotational angle, the means for mounting the legs being adapted to permit the legs to be swung outwardly beyond operative position and back to engage and disengage the heads of the pins when the heads are properly positioned by rotation of the bar.
Claim 2
Dependent Claim
162 words
A folding trestle table comprising a top, a pair of legs spaced longitudinally of the top, and means supporting the legs from the top for folding and unfolding movement longitudinally of the top, a trestle bar assembly including a bracket supported on the under surface of the top for swinging movement transversely of the top, and a trestle bar member carRied by the bracket by means permitting the bar to be rotated around its longitudinal axis the trestle bar having pins projecting outwardly from its ends respectively, said pins having heads of different crosssectional dimensions, and the legs defining slots adapted when the parts are unfolded to receive the heads respectively when the heads are presented at the proper rotational angle, the means for mounting the legs being adapted to permit the legs to be swung outwardly beyond operative position and back to engage and disengage the heads of the pins when the heads are properly positioned by rotation of the bar.
Claim 3
Dependent Claim
81 words
The table structure claimed in claim 1 in which each leg is I shaped having parallel cross bars at either end of an intermediate portion, means for mounting one cross-bar of each leg on the under side of the top for rotation around an axis extending transversely of the top, and means positioned between the mounted cross bar and an end of the table for yieldingly and resiliently opposing unfolding movement of the leg substantially beyond its operative table supporting position.
Claim 4
Dependent Claim
95 words
The table structure claimed in claim 1 in which the bracket comprises a member extending longitudinally of the top between the longitudinally spaced leg mounting means, arms projecting from said member and normal to said member, said arms each having a bore extending through it longitudinally of the table, the said pins extending through the bores in said arms respectively which are thereby rotatably mounted within said assembly, and hinge means interconnecting said bracket member and the table top and disposed for folding and unfolding movement of the trestle bar assembly transversely of the top.
