Abstract
Abstract An anchor fitting has flat surfaced pads with shoulders extending therefrom and a post portion extending along an axis substantially normal to the flat surfaces of the pads. A fastening device is provided on the post for anchoring a load to a track on which the fitting is removably mounted. The device further includes a screw adjustable plunger and clamp member which can be adjustably positioned by the screw along an axis substantially normal to the flat surfaces of the pads. The fitting is removably retained in a selected position along a slotted track, having a plurality of notched portions separated by narrow neck portions formed by flanges, with the shoulders of the pads and the track slots underneath the flanges and with the plunger lowered by the screw so that it is seated in one of the notched portions of the track with a clamping shoulder portion of the plunger-clamp unit in tight engagement with the top surface of the track. This provides a tight, rattle-proof joinder between the fitting and the track.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
344 words
An anchor fitting for securing a load to a slotted retainer track (30), said track (30) having notched portions (30a) separated by narrow neck portions (30b), said fitting comprising: a main body portion (14) having opposite sides and base pad means (15) with a substantially flat bottom surface (15) and shoulders (15a) extending therefrom in a direction substantially parallel to said surface, a plunger-clamp member (23) supported on said main body portion (14) for movement relative thereto along an axis substantially normal to the flat bottom surface (15) of the main body portion (14), said plunger-clamp member (23) having a pair of opposing arms, (23a, 23b) which overlap the opposite sides of said main body portion (14), a projection (32) having a curved surface (32a) extending downwardly from each of said arms 23a, 23b towards the base pad means (15), said projection (32a) fitting in the notched portions (30a) of the track (30) in mating engagement therewith, and a shoulder formed on each of said arms (23a, 23b) directly above each of said projections (32), screw means (25) slidably fitted through said plunger-clamp member (23) in rotatable relationship thereto and threadably engaging said body portion (14) for slidably positioning the plunger-clamp member (23) along said axis, and means (26) for restraining said screw means (25) against any substantial longitudinal movement relative to the plunger-clamp member (23), said screw means (25) being rotated in a first direction to drive the plunger-clamp member (23) along said axis to a first predetermined position whereat the plunger-clamp member projections (32) form a plunger which is seated in one of the track notched portions (30a) and the shoulders (35a, 35b) formed on the arms (23a, 23b) and the shoulders (15a) of the base pad means (15) are in firm abutment against the track (30) to secure the fitting to the track (30), said screw means (25) being rotated in a direction opposite said first direction to drive the plunger-clamp member (23) along said axis to a second predetermined position whereat the fitting can be removed from the track (30).
Claim 2
Dependent Claim
344 words
An anchor fitting for securing a load to a slotted retainer track (30), said track (30) having notched portions (30a) separated by narrow neck portions (30b), said fitting comprising: a main body portion (14) having opposite sides and base pad means (15) with a substantially flat bottom surface (15) and shoulders (15a) extending therefrom in a direction substantially parallel to said surface, a plunger-clamp member (23) supported on said main body portion (14) for movement relative thereto along an axis substantially normal to the flat bottom surface (15) of the main body portion (14), said plunger-clamp member (23) having a pair of opposing arms, (23a, 23b) which overlap the opposite sides of said main body portion (14), a projection (32) having a curved surface (32a) extending downwardly from each of said arms 23a, 23b towards the base pad means (15), said projection (32a) fitting in the notched portions (30a) of the track (30) in mating engagement therewith, and a shoulder formed on each of said arms (23a, 23b) directly above each of said projections (32), screw means (25) slidably fitted through said plunger-clamp member (23) in rotatable relationship thereto and threadably engaging said body portion (14) for slidably positioning the plunger-clamp member (23) along said axis, and means (26) for restraining said screw means (25) against any substantial longitudinal movement relative to the plunger-clamp member (23), said screw means (25) being rotated in a first direction to drive the plunger-clamp member (23) along said axis to a first predetermined position whereat the plunger-clamp member projections (32) form a plunger which is seated in one of the track notched portions (30a) and the shoulders (35a, 35b) formed on the arms (23a, 23b) and the shoulders (15a) of the base pad means (15) are in firm abutment against the track (30) to secure the fitting to the track (30), said screw means (25) being rotated in a direction opposite said first direction to drive the plunger-clamp member (23) along said axis to a second predetermined position whereat the fitting can be removed from the track (30).
Claim 3
Dependent Claim
26 words
