Bendable rolling conveyor guide

Abstract

A readily bendable rolling conveyor guide is provided. The guide includes axle-positioning members having notches. The axle-positioning members slidably engage channels mounted to a structural support member. A plurality of axles carrying rotatable elements and spacers are disposed between the axle-positioning members. Due to the notches in the axle-positioning members and the unique cross-section of the exterior of the channels, the assembled guide may be bent at small radii without causing distortion of the channels or interference between the axle-positioning members and the channels.

What is claimed is:  
     
         1 . An apparatus for guiding articles moving on a conveyor comprising: 
 an elongated first axle-positioning member and an elongated second axle-positioning member spaced from the first axle-positioning member;    one or more first axles extending between the axle-positioning members with one end of each of said axles being formed integral with said first axle-positioning member and the other end of each of said axles being received in a socket formed in the second axle-positioning member; and    one or more rotatable elements mounted on each of said axles to be engaged by articles moving on a conveyor.    
     
     
         2 . The apparatus of  claim 1 , wherein said second axle-positioning member has one or more second axles having one end formed integral with the second axle-positioning member and with the other end of the second axles extending into sockets formed in the first axle-positioning member, and one or more rotatable elements mounted on the second axles.  
     
     
         3 . The apparatus of  claim 2 , wherein the first axles fit between the second axles.  
     
     
         4 . The apparatus of  claim 1 , including spacers positioned on said axles so that rotatable elements on one axle are vertically offset with respect to the rotatable elements on adjacent axles.  
     
     
         5 . The apparatus of  claim 4 , wherein the spacers are formed integral with at least one of said axle-positioning members.  
     
     
         6 . The apparatus of  claim 1 , wherein said axle other ends or said sockets are tapered to facilitate the entry of the axles into the sockets.  
     
     
         7 . The apparatus of  claim 1 , including first and second guide rails having channels to receive said axle-positioning members in a manner to maintain the axles within the sockets.  
     
     
         8 . The apparatus of  claim 7 , wherein said rails and said axle-positioning members are rigid but bendable so that they may be bent into a curved configuration.  
     
     
         9 . The apparatus of  claim 8 , wherein said axle-positioning members have notched edges which facilitate curving of the axle-positioning members.  
     
     
         10 . The apparatus of  claim 9 , wherein said first and second guide rails have a surface that includes a V-shaped protrusion along the outside of the rails.  
     
     
         11 . The apparatus of  claim 1 , wherein said axle-positioning members are rigid but bendable so that they may be bent into a curved configuration.  
     
     
         12 . The apparatus of  claim 11 , wherein said axle-positioning members have notched edges which facilitate curving of the axle-positioning members.  
     
     
         13 . An apparatus for guiding articles moving on a conveyor comprising: 
 an elongated first axle-positioning member and an elongated second axle-positioning member spaced from the first axle-positioning member;    one or more spacers, with each of said spacers being formed integral with one of said axle-positioning members;    one or more sockets formed in each of the axle-positioning members;    one or more axles extending between the axle-positioning members; and    one or more rotatable elements mounted on each of said axles to be engaged by articles moving on a conveyor.    
     
     
         14 . The apparatus of  claim 13 , wherein said axles are tapered at either or both of a first end and a second end, or said sockets are tapered to facilitate the entry of the axles into the sockets.  
     
     
         15 . The apparatus of  claim 13 , including first and second guide rails having channels to receive said axle-positioning members in a manner to maintain the axles within the sockets.  
     
     
         16 . The apparatus of  claim 15 , wherein said rails and said axle-positioning members are rigid but bendable so that they may be bent into a curved configuration.  
     
     
         17 . The apparatus of  claim 16 , wherein said axle-positioning members have notched edges which facilitate curving of the axle-positioning members.  
     
     
         18 . The apparatus of  claim 17 , wherein said first and second guide rails have a surface that includes a V-shaped protrusion along the outside of the rails.  
     
     
         19 . An apparatus for guiding articles moving on a conveyor comprising: 
 a pair of spaced elongated axle-positioning members having notched edges;    a plurality of axles extending between said axle-positioning members; and    one or more rotatable elements mounted on each of said axles, said notched edges of said axle-positioning members being configured to locate one notch on each edge between each axle, the notches facilitating curving of the axle-positioning members about an axis that is perpendicular to their longitudinal axis.    
     
     
         20 . The apparatus of  claim 19 , including a pair of spaced, elongated rails each having a channel for respectively receiving one of the axle-positioning members.  
     
     
         21 . The apparatus of  claim 20 , wherein said guide rails have a section that includes a V-shaped protrusion along the outside of the rails.  
     
     
         22 . A method of assembling a rolling conveyor guide comprising the steps of: 
 providing an axle-positioning member having integral formed axles, wherein the axles are oriented upward;    placing an appropriate number of rotatable elements upon the axles;    securing a second axle-positioning member to the free ends of the axles; and    slidably inserting the assembled axle-positioning members and rotatable elements into a support structure, wherein the support structure has spaced channels adapted to receive the axle-positioning members.    
     
     
         23 . The method of  claim 22 , wherein the second axle-positioning member is horizontally offset from the first axle-positioning member, such that the ends of the second axle-positioning member do not directly oppose the ends of the first axle-positioning member.  
     
     
         24 . The method of  claim 22 , further comprising the step of bending the support structure and axle-positioning members.
