Retainer and method for attaching lines to lightweight elements of means of transport, in particular to sandwich panels of aircraft

Abstract

A retainer for attaching lines to lightweight elements of means of transport, in particular to sandwich panels of aircraft, with at least one base plate comprising at least one retaining stud. The retaining stud or studs can be cemented into a borehole within a lightweight element. The retaining studs are designed to be free of any undercut, and are connected in one piece to the base plate. A method is also provided for attaching lines to lightweight elements of means of transport, in particular to sandwich panels of aircraft, by means of a retainer comprising at least one retaining stud and a base plate.

1 . A retainer for attaching lines to lightweight elements of means of transport, including to sandwich panels of aircraft, comprising: 
 a base plate;    at least one retaining stud being adapted to be cemented into a borehole within a lightweight element,    wherein the at least one retaining stud is designed to be free of any undercut, and is connected in one piece to the base plate.    
     
     
         2 . The retainer of  claim 1 , wherein the at least one retaining stud comprises an attachment section, wherein the attachment section can be inserted into a borehole in the lightweight element.  
     
     
         3 . The retainer of  claim 1 , wherein the attachment section comprises a top section, a middle section and an end section.  
     
     
         4 . The retainer of  claim 3 , wherein the top section and the end section are essentially disc-shaped, with the diameter of the top section and the diameter of the end section essentially corresponding to the borehole diameter of the respective borehole.  
     
     
         5 . The retainer of  claim 3 , wherein at least in some sections the cross-sectional area of the middle section is smaller than the cross-sectional area of the respective borehole so as to form a hollow space for accommodating adhesive.  
     
     
         6 . The retainer of  claim 5 , wherein the adhesive for attaching the retaining stud or retaining studs in the borehole can be placed into the hollow space in the lightweight element.  
     
     
         7 . The retainer of  claim 3 , wherein at least in some sections the cross-sectional geometry of the middle section is other than circular.  
     
     
         8 . The retainer of  claim 3 , wherein the middle section comprises at least one resistance element, in particular at least one projection, at least one indentation or the like.  
     
     
         9 . The retainer of  claim 1 , wherein the at least one retaining stud comprises at least one filling channel, into which adhesive may be placed, and at least one outlet channel for venting and indicating a fill level.  
     
     
         10 . The retainer of  claim 1 , wherein at least one line can be attached directly in the region of the base plate.  
     
     
         11 . The retainer of  claim 1 , wherein the base plate comprises at least one lead-through for attaching at least one attachment means, in particular at least one cable tie.  
     
     
         12 . The retainer of  claim 1 , further comprising: 
 an adapter for attaching the line or lines can be attached to the base plate.    
     
     
         13 . The retainer of  claim 12 , wherein the adapter comprises at least one lead-through for attaching at least one attachment means, in particular at least one cable tie.  
     
     
         14 . The retainer of  claim 5 , wherein the adhesive comprises a plastic material, in particular a low-viscosity rapid-hardening plastic material.  
     
     
         15 . A method for attaching lines to lightweight elements of means of transport, including to sandwich panels of aircraft, by means of a retainer comprising at least one retaining stud and a base plate comprising: 
 providing the lightweight element with at least one borehole;    inserting the at least one retaining stud into the respective borehole;    pacing adhesive into the respective borehole through at least one filling channel in the at least one retaining stud so as to attach the retainer in the lightweight element, and attaching at least one line in the region of the base plate.    
     
     
         16 . The method of  claim 15 , further comprising: 
 attaching an adapter in the region of the base plate; and    attaching the at least one line to the adapter.    
     
     
         17 . The method of  claim 15 , further comprising: 
 pacing an adhesive is placed into the at least one filling channel until the adhesive issues from the at least one outlet channel.
