Abstract

An overcenter load binder to be connected to and tighten toward one another two chains or the like, and including two tension elements connectable to the chains respectively, and an actuating lever pivoted to the tension elements at different locations to attain an overcenter tightening action, with one of the tension elements having a bifurcated portion with two arms between which the lever is received in a load tightening position, and with those arms containing two aligned apertures for receiving a padlock or the like at a location blocking load releasing swinging movement of the lever.

Claims

1. An overcenter load binder for interconnecting two members and tightening them toward one another, comprising:

a first tension element adapted to be connected to one of said members and having a bifurcated portion defining two spaced arms;

a second tension element adapted to be connected to the other of said members;

an actuating lever having a swinging handle portion at one end thereof;

first pivotal connection means attaching said lever toward a second end thereof to said first tension element for relative swinging movement about a first pivotal axis between a load tightening position in which an intermediate portion of said lever between said handle and said first axis is received between said two arms of said first tension element, and a released position; and

second pivotal connection means attaching said second tension element to said lever for relative pivotal about an axis offset from said first pivotal axis at a location to pull said members relatively together and be slightly overcenter with respect to said first axis when the lever is in said load tightening position;

said two arms of said first tension element having portions projecting outwardly beyond said intermediate portion of said lever in said load tightening position thereof and containing aligned apertures adapted to receive a locking part in a position of extension through said apertures and across an outer side of said intermediate portion of said lever between said arms in a relation blocking swinging movement of said lever from said load tightening position to said released position.

2. An overcenter load binder as recited in claim 1, in which said handle portion of the lever in swinging between said load tightening and released positions swings outwardly at a predetermined side of said tension elements, said first tension element having an attaching portion through which is it secured to said one member and from which said two arms project in a direction toward said predetermined side of said first tension element at which said lever swings.

3. An overcenter load binder as recited in claim 1, in which said second end of said lever is bifurcated to form two spaced projections between which said second tension element is received and to which said second tension element is pivotally connected by said second pivotal connection means.

4. An overcenter load binder as recited in claim 1, in which said two apertures of said arms are adapted to receive the locking part of a padlock.

5. An overcenter load binder as recited in claim 1, including a padlock having its locking part extending through and between said apertures of said arms.

6. An overcenter load binder as recited in claim 1, in which said bifurcated portion of said first tension element has two additional arms received at opposite sides of said lever and projecting generally perpendicular to said first arms.

7. An overcenter load binder as recited in claim 1, in which said bifurcated portion of said first tension element has two additional arms received at opposite sides of said lever and projecting generally perpendicular to said first arms, said second pivotal connection means including two aligned pivotal connections attaching said two additional arms respectively to said lever.

8. An overcenter load binder as recited in claim 7, in which said lever is bifurcated to form two arms connected to said two additional arms respectively of said first tension element by said two aligned pivotal connections respectively, said second tension element extending into said bifurcated portion of said lever between said two arms thereof and being pivotally connected to the lever by said second connection means at a location between said arms of the lever.
