Abstract
The trench shoring apparatus includes first and second side panels connected in a parallel spaced-apart configuration by a connecting rod pivotally connected to one end of one or more pairs of lateral arms. The other opposite end of the one or more pairs of lateral arms is hingedly connected to the side panels, such that translational movement of the connecting rod in a direction parallel to the side panels causes the spaced-apart panels to move between retracted and extended parallel spaced-apart configurations.
Claims20
A trench shoring apparatus, comprising:
- first and second side panels having a retracted parallel spaced-apart configuration and an extended parallel spaced-apart configuration;
- a first pair of lateral arms, one first lateral arm of said first pair of lateral arms having one first lateral arm end hingedly connected to said first side panel, and another first lateral arm of said first pair of lateral arms having another first lateral arm end hingedly connected to said second side panel;
- a second pair of lateral arms, one second lateral arm of said second pair of lateral arms having one second lateral arm end hingedly connected to said first side panel, and another second lateral arm of said second pair of lateral arms having another second lateral arm end hingedly connected to said second side panel;
- and
- a connecting rod having a fixed length between said first pair of lateral arms and said second pair of lateral arms and being pivotally connected to an opposite first lateral arm end of said one first lateral arm, another opposite first lateral arm end of said another first lateral arm, an opposite second lateral arm end of said one second lateral arm, and another opposite second lateral arm end of said another second lateral arm so as to move said first side panel and said second side panel between said retracted parallel spaced-apart configuration and said extended parallel spaced-apart configuration according to translational movement of said fixed length of said connecting rod along a direction parallel to said first side panel and said second side panel and along a longitudinal axis of said connecting rod.
