Luggage case having an engaging mechanism for easily exchanging a pulling rod mechanism

Abstract

A luggage case having an engaging mechanism for easily exchanging a pulling rod mechanism is disclosed. It can be used for an interior-typed or exterior-typed pulling rod mechanism. When it is the interior-typed condition, a locking plate is disposed near the top of the case. A lower receiving seat is disposed at the bottom inside the case for inserting the ends of the outer tubes. An upper cover seat is disposed on the outer tubes for locking or releasing from the locking plate. The engaging mechanism has two hooks and a button. So, by pressing the button, the user can control the pulling rod mechanism to lock on or release from the case. When it is the exterior-typed condition, the user still can easy control the pulling rod mechanism to be locked or released. Therefore, this invention's structure is simple. With destroying the case, its pulling rod mechanism can be quickly and easily exchanged.

What is claimed is:  
     
         1 . A luggage case having an engaging mechanism for easily exchanging a pulling rod mechanism, said luggage case mainly being used for an interior-typed pulling rod mechanism, comprising: 
 (a) a case having an upper portion and an inner bottom, a locking plate being mounted on said upper portion and having two stopping surfaces, a lower receiving seat being mounted on said inner bottom and having several engaging holes;    (b) a pulling rod mechanism having outer tubes, an upper cover seat having hole for fitting with said outer tubes, ends of the outer tubes being inserted into said engaging holes of said lower receiving seat of said case; and    (c) an engaging mechanism, said engaging mechanism being disposed in said upper cover seat of said pulling rod mechanism, said engaging mechanism having a hook for locking with said stopping surfaces of said locking plate of said case so as to attach said pulling rod mechanism on said case, said engaging mechanism further having a button protruded over the hole of said upper cover seat so as to allow a user to press and control the hooks.    
     
     
         2 . A luggage case having an engaging mechanism for easily exchanging a pulling rod mechanism, said luggage case mainly being used for an exterior-typed pulling rod mechanism, comprising: 
 (a) a case having an upper outer portion and a lower outer portion, a locking plate being mounted on said upper outer portion and having two stopping surfaces, a holding seat with a staged surface being mounted on the lower outer portion of said case;    (b) a pulling rod mechanism having outer tubes, an upper cover seat having holes for fitting with said outer tubes corresponding to the position of said locking plate, said pulling rod mechanism having a lower seat having a hook portion corresponding to the position of said holding seat of said case; and    (c) an engaging mechanism, said engaging mechanism being disposed in one side of said upper cover seat of said pulling rod mechanism, said engaging mechanism having hooks for locking with said stopping surfaces of said locking plate of said case so as to attach said pulling rod mechanism on said case, said engaging mechanism further having a button protruded over a hole of said upper cover seat so as to allow a user to press and control the hook.    
     
     
         3 . A luggage case having an engaging mechanism for easily exchanging a pulling rod mechanism, said luggage case mainly being used for an exterior-typed pulling rod mechanism, comprising: 
 (a) a case having an upper outer portion and an lower outer, two locking plates being mounted on said upper and lower outer portions respectively and having several stopping surfaces;    (b) a pulling rod mechanism having outer tubes, an upper cover seat having holes for fitting with said outer tubes, a lower cover seat being disposed at ends of said outer tubes; and    (c) two engaging mechanisms, said engaging mechanisms being disposed in said upper and lower cover seats of said pulling rod mechanism, each of said engaging mechanisms having two hooks for locking with said stopping surfaces of said locking plate of said case so as to attach said pulling rod mechanism on said case, each of said engaging mechanisms further having a button protruded over a hole of said upper cover seat so as to allow a user to press and control the hooks.    
     
     
         4 . A luggage case having an engaging mechanism for easily exchanging a pulling rod mechanism as claimed in claims  1 ,  2  or  3 , wherein: 
 said stopping surfaces are formed in stepped shapes, and two lateral sides of said stopping surfaces are disposed with two limiting slots so as to engage with said hooks of said engaging mechanism.  
 
     
     
         5 . A luggage case having an engaging mechanism for easily exchanging a pulling rod mechanism as claimed in claims  1 ,  2  or  3 , wherein: 
 said engaging mechanism includes: 
 a cover having two recesses on both sides, for covering two sliding elements, hooks being disposed on outer edges of said sliding elements, each hook having a sloped surface at its bottom for contacting with said recesses, said hooks being protruded over said cover;  
 two protrusions with springs being disposed on two opposite ends of said two sliding elements, each protrusion having a guiding surface corresponding to said sloped surface;  
 a button being disposed between said two guiding surfaces;  
 two stopping blocks being disposed above two sides of said button;  
 two tilted surfaces being disposed below two sides of said button so as to mate with said two sliding elements so that said cover will lock on said corresponding cover.  
 
 
     
     
         6 . A luggage case having an engaging mechanism for easily exchanging a pulling rod mechanism as claimed in claims  1 , wherein: 
 a receiving slot with two through holes is disposed on a top surface of said case, said through holes are provided for inserting with said outer tubes, so that the ends of the outer tubes are engaged in said engaging holes of said lower receiving seat, and said upper cover seat of said pulling rod mechanism can be installed in said receiving slot.
