Telescopic handle

Abstract

A telescopic handle for transportable containers, such as suitcases or trolley cases, includes an upper central elongated element connected to two lateral elongate elements, which move from an extracted condition to a condition inserted in seats provided inside the container. The central elongated element moves from a maximum spaced apart condition, corresponding to the extracted condition, to a maximum approaching condition, corresponding to the inserted condition, and a hooking system, which can be activated or deactivated, of at least one lateral elongated element can maintain stably the extracted condition or the inserted condition. Activation or deactivation is generated by having a handle part of the central elongated element be pivotally mounted with respect to the longitudinal axis of the central elongated element and to be configured so that the rotation of the handle part causes the hooking system to be activated or deactivated.

The invention claimed is: 
     
         1 . A telescopic handle for transportable containers, comprising:
 an upper central elongated element ( 20 );   two lateral elongated elements ( 30 ) connected to the central elongated element ( 20 ), the lateral elongated elements ( 30 ) moving from an extracted condition to an inserted condition in special seats provided inside a container, the central elongated element ( 20 ) moving from a maximum spaced apart condition, corresponding to the extracted condition, to a maximum approaching condition, corresponding to the inserted condition, with respect to said container;   means for hooking at least one of the lateral elongated elements ( 30 ), the means for hooking being configured to stably maintain the extracted condition or the inserted condition; and   means for activating/deactivating said means for hooking,   wherein:   said means for activating/deactivating comprise a handle part ( 21 ) belonging to said central elongated element ( 20 ), and   the handle part ( 21 ) is pivotally mounted with respect to a longitudinal axis of the central elongated element ( 20 ) and is configured so that a rotation of the handle part ( 21 ) causes the means for hooking to be activated/deactivated.   
     
     
         2 . The telescopic handle according to  claim 1 , wherein said central elongated element ( 20 ) comprises means ( 22 ) for transforming a rotational movement of said handle part ( 21 ), the means ( 22 ) for transforming being configured as to transform the rotation of said handle part ( 21 ) into a translation movement, and wherein the hooking means are provided with transmission means ( 23 ) of said translation movement. 
     
     
         3 . The telescopic handle according to  claim 2 , wherein said means ( 22 ) for transforming comprise at least a first part ( 221 ) positioned adjacently to, and in contact with, an end of said handle part ( 21 ), and a second part ( 222 ) in contact with said first part ( 221 ), the second part ( 222 ) being translatable with respect to said first part ( 221 ), so that said second part ( 222 ) moves from an approached condition to a spaced apart condition with respect to said first part ( 221 ), and wherein, in an approached condition, the first part ( 221 ) and the second part ( 222 ) define a housing seat ( 220 ) for a pusher element ( 224 ) integral with said handle part ( 21 ), so that, during the rotation of said handle part ( 21 ), external walls of the pusher element ( 224 ) push the second part ( 222 ), which in turn transmits the translation movement to said transmission means ( 23 ). 
     
     
         4 . The telescopic handle according to  claim 3 , wherein the said pusher element ( 224 ) consists of a pin ( 2241 ) having at least one protruding head ( 2242 ), the first ( 221 ) and the second ( 222 ) parts have insertion seats for ends of said pin ( 2241 ),
 said first part ( 221 ) having a first face ( 2211 ) facing in a direction of a second face ( 2221 ) belonging to said second part ( 222 ), the first ( 2211 ) and the second ( 2221 ) faces having a profile complementary to a shape of said protruding head ( 2242 ), so that in an approached condition the first and the second faces ( 2211 ,  2221 ) the housing seat ( 220 ) of said protruding head ( 2242 ) and so that during the rotation of said handle part ( 21 ), the protruding head ( 2242 ) flows along a profile of said first and said second faces ( 2211 ,  2221 ) and pushes the second part ( 222 ) in the spaced apart condition.   
     
     
         5 . The telescopic handle according to  claim 4 , wherein the protruding head ( 2242 ) consists of a wheel having an axis of rotation perpendicular to a longitudinal axis of said pin ( 2241 ). 
     
     
         6 . The telescopic handle according to  claim 4 , wherein said pin ( 2241 ) has two protruding heads ( 2242 ), positioned diametrically opposite to a section of said pin ( 2241 ). 
     
     
         7 . The telescopic handle according to  claim 4 , wherein at least one end of said central elongated element ( 20 ) is connected with a corresponding lateral elongated element ( 30 ) through a curvilinear element, the curvilinear element having a channel ( 231 ) that provides a course corresponding to a profile of said curvilinear element, the transmission means comprising a plurality of spheres ( 232 ) inserted within said channel ( 231 ) and arranged adjacent to each other, the plurality of spheres being adjacent to said second part ( 222 ) in connection with said central elongated element ( 20 ). 
     
     
         8 . The telescopic handle according to  claim 3 , wherein said means ( 22 ) for transforming are positioned at both ends of said central elongated element ( 20 ). 
     
     
         9 . The telescopic handle according to  claim 1 , wherein said handle part ( 21 ) has at least one upper external wall made to be flush with an upper external wall of a remaining part ( 24 ) of the central elongated element ( 20 ) in an non-rotated condition of said handle part ( 21 ). 
     
     
         10 . A transportable container comprising:
