Mountings for rack mounted device

Abstract

A rack engaging member is provided having first and second elements spaced apart one from the other at a predetermined distance which is determined by a first distance at which two openings in a standard rack for receiving electronic devices are spaced apart one from the other. One of the first and second elements is positionable to span the difference in spacing between a pair of rack openings spaced at the first distance one from the other and a different pair of rack openings in the standard rack which are spaced at a second, different, distance one from the other. As a result, devices may be mounted in manners which span the differential spacings of holes between the sets of three provided in the standard rack.

1 . Apparatus comprising: 
 a rack engaging member having first and second elements spaced apart one from the other at a predetermined distance which is determined by a first distance at which two openings in a standard rack for receiving electronic devices are spaced apart one from the other;    one of said first and second elements being positionable to span the difference in spacing between a pair of rack openings spaced at the first distance one from the other and a different pair of rack openings in the standard rack which are spaced at a second, differing, distance one from the other.    
   
   
       2 . Apparatus according to  claim 1  wherein said rack engaging member comprises a carriage and said first and second elements are a pair of pins mounted in said carriage, one of said pins being in fixed position relative to said carriage and the other of said pins being adjustable in position relative to said one fixed pin.  
   
   
       3 . Apparatus according to  claim 2  further comprising a third element mounted in said carriage and being adjustable in position relative to said one fixed pin, said third element being movable relative to said carriage in two orthogonal directions.  
   
   
       4 . Apparatus according to  claim 2  wherein each of said pair of pins is a shouldered protrusion from said carriage defining a terminal portion having a first diameter and a proximal portion having a greater diameter, each pin being enabled to enter into and engage rack openings of two differing diameters.  
   
   
       5 . Apparatus according to  claim 4  wherein said other pin is mounted in said carriage in an elongated slot for movement toward and away from said fixed pin along an axis extending through said terminal portions of said pins.  
   
   
       6 . Apparatus according to  claim 4  comprising a third element mounted in said carriage and being adjustable in position relative to said one fixed pin, said third element being movable relative to said carriage in two orthogonal directions, one of which is defined by an axis extending through said terminal portions of said pins and the other of which is parallel to an axis extending in the direction of the protrusion of said pins.  
   
   
       7 . Apparatus according to  claim 6  wherein said third element comprises a fastener for coupling a device to said carriage.  
   
   
       8 . Apparatus according to  claim 1  wherein said rack engaging member comprises a bracket and said first and second elements define a pair of spaced openings in said bracket aligned along a predetermined axis, each of said openings being an elongated slot and the elongation of said slots having a lengthwise dimension along said axis such that the first and second elements span the difference in spacing between a pair of rack openings spaced at the first distance one from the other and a different pair of rack openings in the standard rack which are spaced at a second, greater, distance one from the other.  
   
   
       9 . Apparatus according to  claim 8  further comprising a keeper member mounted on said bracket and movable between a position overlying said slots and a position withdrawn from said slots, said keeper member when overlying said slots assuring that a desired positioning in a rack is maintained.  
   
   
       10 . Apparatus according to  claim 8  wherein said bracket is planar and further comprising a locator pin mounted on said bracket intermediate said slots and projecting from said bracket to aid in aligning rack mounted devices.
