Abstract
Abstract A tie down device adapted to be secured selectively to an anchorage member having a web provided with either a circular opening or an anchorage member having a web provided with an elongated opening. The tie down device has an opening of its own for receiving the end fitting of lashing means and is retained within the openings of the anchorage members by an integral elongated flange. Depending upon the thickness of the web of the anchorage member, a notch in the shank element of the tie down device may operate as an integral lock engaging the web thereby functioning as an integral lock further to prevent the tie down device from disengaging under load.

Total Claims: 6
Claim 1
Independent Claim
217 words
A selectively operable tie down device adapted to secure an anchorage member to a support member, the device having a longitudinal axis, the anchorage member having a web with a circular opening or an elongated opening and an interior side wall adjacent the opening, said device comprising: a. a base member having at least one first elongated flange dimensioned to be insertable into said opening in a first position and movable to a second position whereby the dimensions of said flange exceed the dimensions of said opening to lock said flange within the web against movement out of the web in a direction parallel to the axis of the tie down device; b. at least one beveled surface in said base member offset from the axis of the tie down device and positioned such that it can be used in cooperation with an anchorage member having an interior surface dimensioned to engage said beveled surface if the device is partially rotated about its axis to preclude further rotational movement of said base member in the direction of rotation; c. a shank member extending from said base member; and d. at least a first head member connected to the shank member having means for attaching a tensioning element thereto for securing the anchorage member to the support member.
Claim 2
Dependent Claim
217 words
A selectively operable tie down device adapted to secure an anchorage member to a support member, the device having a longitudinal axis, the anchorage member having a web with a circular opening or an elongated opening and an interior side wall adjacent the opening, said device comprising: a. a base member having at least one first elongated flange dimensioned to be insertable into said opening in a first position and movable to a second position whereby the dimensions of said flange exceed the dimensions of said opening to lock said flange within the web against movement out of the web in a direction parallel to the axis of the tie down device; b. at least one beveled surface in said base member offset from the axis of the tie down device and positioned such that it can be used in cooperation with an anchorage member having an interior surface dimensioned to engage said beveled surface if the device is partially rotated about its axis to preclude further rotational movement of said base member in the direction of rotation; c. a shank member extending from said base member; and d. at least a first head member connected to the shank member having means for attaching a tensioning element thereto for securing the anchorage member to the support member.
Claim 3
Dependent Claim
73 words
The tie down device according to claim 1 wherein said head member includes a second flange extending substantially perpendicular to the axis of said shank and spaced from said base member such that when a tension force is applied to said head member said second flange will contact an exterior surface of the web and firmly secure the tie down device to the web thereby preventing pivotal movement of the tie down device.
Claim 4
Dependent Claim
102 words
The tie down device according to claim 1 wherein the surface of said first elongated flange facing away from the head member has at least one beveled portion to facilitate insertion of the tie down device into a circular opening of a web whereby the base member is inserted into said opening in a first position and moved to a second locking position and the dimensions of said first elongated flange exceed the dimensions of said opening to lock said flange within the web against movement out of the web in a direction parallel to the axis of the tie down device.
Claim 5
Dependent Claim
99 words
A tie down device according to claim 1 wherein at least a portion of the surface of said shank element is configured to define a portion of a notch, one side portion of said notch being formed by said first elongated flange of said base member, said notch being configured to receive a portion of the web of the anchorage member such that upon the application of a tension force to said head member, said web member contacts at least a side portion of said notch to facilitate locking engagement of said tie down device to said anchorage member.
Claim 6
Dependent Claim
102 words
The tie down device according to claim 19 having a second head member connected to the first head member, said second head member having a third locking flange portion extending substantially perpendicular to the axis of said tie down device, said second head member adapted for insertion into an opening of a top corner end of an anchorage member such that when a tension force is applied to said first head member, the third locking flange portion engages the web of the corner member and precludes movement of the tie down device out of the top corner end of the anchorage member.
