Support for construction site layout lines

Abstract

A support for layout lines utilized in laying out construction sites. The support is slidably carried on a stake and includes a clamping bolt to fix it in position on the stake and to allow it to be moved along the stake for adjustment purposes. The support includes a transit pole tab, on which the bottom of a transit pole can be placed for positioning purposes, and a tab for supporting a layout line platform. A clamping member, such as a thumbscrew, is carried in a bracket and overlies the platform to allow the thumbscrew to clamp the layout line in position against the upper face of the platform, which can include a groove or slot for receiving the layout line. The upper surface of the transit pole tab lies in the same plane as the upper surface of the layout line platform.

What is claimed is:  
     
         1 . A layout line support member comprising: 
 a) a support body having a longitudinal axis;    b) a first lateral member carried by the support body and including a laterally-extending locating surface;    c) a second lateral member carried by the support body and circumferentially offset from the first lateral member, the second lateral member including a transversely-extending platform including a layout line support surface; and    d) a line clamping member carried by the second lateral member for clamping and holding a layout line in a desired position relative to the support body.    
     
     
         2 . A layout line support in accordance with  claim 1 , wherein the support body includes a longitudinally-extending through passageway to allow the support body to be slidably carried on a layout stake.  
     
     
         3 . A layout line support in accordance with  claim 2 , wherein the support body is a tubular structure.  
     
     
         4 . A layout line support in accordance with  claim 2 , including a holding member carried by the support body for securing the support body to the stake at a desired position.  
     
     
         5 . A layout line support in accordance with  claim 4 , wherein the holding member is threadedly carried by the support body.  
     
     
         6 . A layout line support in accordance with  claim 1 , wherein the line clamping member is a thumb screw having a free end for contacting a layout line and positioned to hold the line against the first lateral member.  
     
     
         7 . A layout line support in accordance with  claim 6 , wherein the thumb screw includes a swivel pad at its free end for engaging and clamping the layout line against the first lateral member.  
     
     
         8 . A layout line support in accordance with  claim 1 , including a transversely-extending tubular support carried by the second lateral member for slidably supporting an extension bar.  
     
     
         9 . A layout line support in accordance with  claim 8 , including an extension bar clamping member carried by the second lateral member for securely holding the extension bar in a desired position relative to the support body.  
     
     
         10 . A layout line support in accordance with  claim 9 , wherein the extension bar slidably supports a second line clamping member for engagement with a second layout line.  
     
     
         11 . A layout line support in accordance with  claim 1 , wherein the layout line support surface includes a linear recess for receiving a portion of the layout line and for positioning the layout line relative to the support body.  
     
     
         12 . A layout line support in accordance with  claim 11 , wherein the linear recess extends across the layout line support surface.  
     
     
         13 . A layout line support in accordance with  claim 11 , wherein the linear recess is formed in an upwardly-extending protrusion carried by the layout line support surface.  
     
     
         14 . A layout line support in accordance with  claim 13 , wherein a pair of spaced, elongated protrusions are provided in the layout line support surface, and each protrusion includes a linear recess, and wherein the linear recesses are aligned with each other.  
     
     
         15 . A layout line support in accordance with  claim 1 , wherein the circumferential offset between the first and second lateral members is from about 120° to about 180°.
