Trench shielding and shoring device

A device for securing sidewalls of an excavation, comprising:

• a first and second panel, each panel having an exterior surface and an interior surface and a pair of distal ends, each panel having a vertical support attached on the interior surface at one of the distal ends, the vertical support of the first panel being arranged to pair in substantially perpendicular coupling relationship with the vertical support of the second panel, each vertical support having a female connection bracket;
• at least two panel connectors, each panel connector having an inside channel and an outside face, a male connection extension attached to the inside channel of each panel connector, and a support bar adaptor attached to the outside face of the panel connector;
• each panel connector being slidably connectable with one of the vertical supports by slidably interlocking the corresponding male connection extension with the female connection bracket of the corresponding vertical support;
• each panel connector having a bottom stop plate;
• and
• a top panel lock to vertically secure the interlocked panel connector and vertical support.

A portable shoring device for securing the sidewalls of an excavation, comprising:

• a pair of panels, each having a generally planar exterior surface, an interior surface and two ends, the paired panels mutually facing each other and being held in spaced-apart relationship by at least one support bar, each panel having two vertical supports attached thereto, the vertical supports on each panel being at opposite ends and arranged to pair in a substantially perpendicular coupling relationship with the corresponding vertical supports of the paired panel, each vertical support traversing along the height of the panel and comprising a first engaging link;
• a plurality of panel connectors, each panel connector having an inside channel, an outside face and a bottom stop plate, a second engaging link attaching to the inside channel of the panel connector, and a support bar adaptor attaching to the outside face of the panel connector, each panel end being removably attached with at least one panel connector by slideably interlocking the first engaging link of the corresponding vertical support with the second engaging link of the panel connector;
• and
• a top panel lock to vertically secure the vertical support within the panel connector.

A method for assembling a portable shoring device, comprising the steps of:

• arranging two panels on a surface being opposite each other in spaced apart relationship, each panel having a vertical support member at an end and the vertical support member having a panel connection bracket, the panel connection bracket facing upward;
• slideably engaging each panel connection bracket with a panel connector until the respective panel engages a stop plate attached to said panel connector, each panel connector having a support bar adaptor attached thereto;
• raising each panel to a vertical standing position and connecting the panels with a support bar by engaging the support bar adaptors so that the panels are vertically opposed in a substantially perpendicular coupling relationship;
• lifting and slideably connecting additional panels until the desired height of the shoring device is reached;
• and
• attaching a top panel lock to a top end of each connection brackets so that the panels are held in place when the portable shoring device is in use.
