Cage nut

Abstract

Cage nut for installation in an elongate, preferably rectangular opening which is only accessible from one side, comprising a nut body with a cylindrical internal thread carrier having an internal thread and an abutment part attached thereto, and a cage encompassing the nut body, wherein the abutment part is adapted to the shape of the opening and has a slightly smaller width and a slightly shorter length than the opening, although the length of the abutment part is significantly greater than the width of the opening; the cage is configured resiliently and is adapted to the shape of the opening such that it can be clipped into the opening and the cage supports stop elements which only allow a rotation of the abutment part with respect to the cage in the screwing-in direction of the internal thread from an installation position parallel to the longitudinal direction of the cage into a retaining position approximately perpendicular thereto.

1 . Cage nut for installation in an elongate, preferably rectangular opening which is only accessible from one side, comprising a nut body with a cylindrical internal thread carrier having an internal thread and an abutment part attached thereto, and a cage encompassing the nut body, characterized in that the abutment part is adapted to the shape of the opening and has a slightly smaller width and a slightly shorter length than the opening, although the length of the abutment part is significantly greater than the width of the opening; in that the cage is configured resiliently and is adapted to the shape of the opening such that it can be clipped into the opening and in that the cage supports stop elements which only allow a rotation of the abutment part with respect to the cage in the screwing-in direction of the internal thread from an installation position parallel to the longitudinal direction of the cage into a retaining position approximately perpendicular thereto. 
     
     
         2 . Cage nut according to  claim 1 , wherein the stop elements are formed such that, in the installation position, they hold the nut body in a floating manner in the cage. 
     
     
         3 . Cage nut according to  claim 1 , wherein the internal thread is provided with a thread securing means (clamping means) in the region remote from the screwing-in side. 
     
     
         4 . Cage nut according to  claim 1 , wherein the cage is configured such that it exerts a spring force on the nut body towards the opening. 
     
     
         5 . Cage nut according to  claim 4 , wherein an annular abutment surface for spring elements of the cage is arranged on the nut body, and this abutment surface is provided with cams or with an undulating profile such that the cams or the elevated portions of the undulating profile engage with the resilient elements of the cage precisely when the nut body leaves its floating installation position in the cage. 
     
     
         6 . Cage nut according to  claim 1 , wherein the stop elements rest on an annular abutment which is arranged in the nut body coaxially to the internal thread on the side facing the opening, and this abutment has recesses for receiving the stop elements, which recesses are arranged such that the stop elements are accommodated therein in the retaining position. 
     
     
         7 . Cage nut according to  claim 6 , wherein the transition from the abutment into the recesses in the direction of rotation is configured as a bevel. 
     
     
         8 . Cage nut according to  claim 6 , wherein the transition from the recesses into the abutment is configured as a stop surface which extends parallel to the axis of rotation of the internal thread.
