Title: Lockset

Description:
BACKGROUND 
     Technical Field 
     The present disclosure relates to a lock, and more particularly to a lockset for a zipper luggage case. 
     Related Art 
     As shown in  FIG. 1 , in order to ensure the safety of baggage, when people go out, the box body  20  having a lockset  90  is often used to load articles. The box body includes, but not limited to, a luggage case, a suitcase and a briefcase. The common lockset includes a combination lock or a key lock, etc. The user opens the box body by dialing a print wheel of the combination lock to a correct unlock password position or inserting a key. During unlocking of the combination lock, an unlocking key  91  needs to be pressed additionally. 
     On the other hand, the lockset  90  can be further used in combination with a zipper  40  of the box body. When the zipper is zipped on, a zipper puller  41  can be inserted or clamped into a lock hole  92  of the above lockset, and then a movable tenon member or button body in the lock hole of the above lockset can penetrate through a through hole of the zipper puller to achieve the locking effect. When being opened, the lockset is unlocked at first, so that the tenon member or button body can be separated from the through hole of the zipper puller. The user can enable the zipper puller  41  to be away from the lock hole  92  and pull the same apart to open the box body. 
     However, since the unlocking key  91  is located on the side surface, it is not easy to adopt the embedded design for the whole lockset  90 , and the probability of damage due to impact on the box body cannot be reduced. In addition, if the box body is relatively large and the zipper and the corresponding lock hole need to be additionally disposed, a corresponding lockset also needs to be additionally disposed, thus the cost is increased, and the operation is not convenient. On the other hand, during border inspection, the user must be next to an inspector to open the lock for inspection, thereby increasing the time and labor costs.

When the lockset  900  is in an unlocked state, the lock body top surface  202  is capable of being pushed by an external force at a position adjacent to the first A-insertion hole  131  to generate a downward displacement, so that the first A clamping hook  310  is rotated to enable the first A insertion hole  131  to be open; and the lock body top surface  202  is capable of being pushed by an external force at a position adjacent to the second A insertion hole  151  to generate a downward displacement, so that the second A clamping hook  510  is rotated to enable the second A insertion hole  151  to be open. 
     The structure of the lockset  900  of the present disclosure will be further described below. According to the embodiment as shown in  FIG. 3A  and  FIG. 3B , the lockset  900  includes a housing, a lock body  200  and a first clamping hook group  300 . The housing  100  includes a housing top surface  102  and a limiting wall  120 . The housing top surface  102  includes a lock body embedding opening  101  and a first A insertion hole  131  located between one side of the lock body embedding opening  101  and one side edge of the housing top surface  102 . The limiting wall  120  is disposed in the housing  100  and includes a limiting hole  121 . The lock body  200  is disposed in the housing  100  and includes a lock body shell  210 , a first lock cylinder  220  and a first shaft rod  230 . The lock body shell  210  includes a lock body top surface  202  and a first side surface  211  located at one end of the lock body shell  210 . The lock body top surface  202  is exposed at the lock body embedding opening  101 , and the first side surface  211  includes a first end hole  212  and a first lug  213  disposed beside the first end hole  212 . The first lock cylinder  220  is disposed in the lock body shell  210 . The first shaft rod  230  is disposed in the lock body shell  210 , and one end  231  of the first shaft rod  230  corresponds to the limiting hole  212 . When the first shaft rod  220  is in an unlocked state, the first shaft rod  230  is capable of moving along the direction of a first axis  234 , such that one end  231  of the first shaft rod  230  enters or is away from the limiting hole  121 . The first lock cylinder  220  includes a combination lock, and the lock body top surface  202  exposes a print wheel of the combination lock. 
     According to the embodiment as shown in  FIG. 3A  and  FIG. 3B , the first clamping hook group  300  is disposed outside the first side surface  211  of the lock body  200  in the housing  100 , and includes a first A clamping hook  310  and a first driving device  320 . The first A clamping hook  310  corresponds to the first A insertion hole  131 , and is capable of selectively rotating to open or close the first A insertion hole  131 . The first driving device  320  abuts against the first lug  213  (referring to  FIG. 3B ) and interferes with the movement of the first A clamping hook  310  (referring to  FIG. 3A ). 
     In the cross-sectional view of the embodiment as shown in  FIG. 4A  and  FIG. 4B , when the first lock cylinder  220  is in an unlocked state, the first shaft rod  230  is capable of moving along the direction of the first axis  234 , such that one end  231  of the first shaft rod  230  is away from the limiting hole  121 , the lock body top surface  202  is capable of being pushed by an external force F at a position adjacent to the first side surface  211 , such that the portion of the lock body shell  210  adjacent to the first side surface  211  generates a downward displacement. In this case, according to the embodiment as shown in  FIG. 5A  and  FIG. 5B , the first lug  213  pushes to move the first driving device  320  to release the limitation on the movement of the first A clamping hook  310 . According to the embodiment as shown in  FIG. 4C  and  FIG. 5C , the first A clamping hook  310  is capable of rotating to open the first A insertion hole  131  as shown in  FIG. 4C  and  FIG. 6A . According to the cross-sectional view of the embodiment as shown in  FIG. 4A , when the first lock cylinder  220  is in a locked state, the movement of the first shaft rod  230  is limited, one end  231  of the first shaft rod  230  enters the limiting hole  121  from the first side surface  211 , to limit the portion of the lock body shell  210  adjacent to the first side surface  211  from generating the downward displacement. In this case, according to the embodiment as shown in  FIG. 5A , the first driving device  320  interferes with the movement of the first A clamping hook  310 , and the rotation of the first A clamping hook  310  is limited to close the first A insertion hole  131  according to the embodiment as shown in  FIG. 4A  and  FIG. 6B . 
     The terms “open” and “closed” refer to that whether the clamping hook blocks a foreign object such as a zipper puller from entering the insertion hole. According to the embodiment as shown in  FIG. 4A  and  FIG. 6B , the hook portion  314  of the first A clamping hook  310  substantially blocks the path where the foreign object enters the first A insertion hole  131 , so the first A insertion hole  131  is “closed”. According to the embodiment as shown in  FIG. 4C , the hook portion  314  of the first A clamping hook  310  is not on the path where the foreign object enters the first A insertion hole  131 , and substantially does not block the foreign object from entering the first A insertion hole  131 . Therefore, the first A insertion hole  131  is “open”. 
     According to the embodiment as shown in  FIG. 3A  and  FIG. 3B , the first driving device  320  includes a force receiving member  321  and a linking member  322 . The force receiving member  321  abuts against the first lug  213  (referring to  FIG. 3B ). The linking member  322  is linked with the force receiving member  321  and interferes with the movement of the first A clamping hook  310 . According to the cross-sectional view of the embodiment as shown in  FIG. 4A  and  FIG. 4B , when the first lock cylinder  220  is in an unlocked state, the first shaft rod  230  is capable of moving along the direction of the first axis  234 , such that one end  231  of the first shaft rod  230  is away from the limiting hole  121 , the lock body top surface  202  is capable of being pushed by an external force F at a position adjacent to the first side surface  211 , such that the portion of the lock body shell  210  adjacent to the first side surface  211  generates a downward displacement. In this case, according to the embodiment as shown in  FIG. 5A  and  FIG. 5B , the first lug  213  pushes to move the force receiving member  321 , the linking member  322  is linked with the force receiving member  321  to release the limitation on the movement of the first A clamping hook  310 . According to the embodiment as shown in  FIG. 4C  and  FIG. 5C , the first A clamping hook  310  is capable of rotating to open the first A insertion hole  131 , as shown in  FIG. 4C  and  FIG. 6A . When the first lock cylinder  220  is in a locked state, the movement of the first shaft rod  230  is limited, one end  231  of the first shaft rod  230  enters the limiting hole  121  from the first side surface  211 , the downward displacement generated by the portion of the lock body shell  210  adjacent to the first side surface  211  is limited, the linking member  322  interferes with the movement of the first A clamping hook  310 , and the rotation of the first A clamping hook  310  is limited to close the first A insertion hole  131 . 
     More specifically, according to the embodiment as shown in  FIG. 3B  and  FIG. 5A , the first lug  213  protrudes toward a first direction  610 . The force receiving member  321  extends along the first direction, and includes a first force receiving end  325  and a force applying end  326 , and the first force receiving end  325  abuts against the first lug  213  (as shown in  FIGS. 5A to 5C ). The linking member  322  extends in a second direction  620  perpendicular to the first direction  610 , the linking member  322  includes a linking member first end  327  and a linking member second end  328  which are located at opposite ends, the linking member first end  327  abuts against the force applying end  326  (as shown in  FIGS. 5A to 5C ), and the linking member second end  328  interferes with the first A clamping hook  310  (as shown in  FIGS. 4A and 5A ). 
     Further, according to the embodiment as shown in  FIG. 4A , the first A clamping hook  310  includes an elastic member  313 , a hook portion  314  and an interfering portion  315 . The elastic member  313  includes a spring. According to the embodiment as shown in  FIG. 4A  and  FIG. 5A , when the linking member second end  328  abuts against the interfering portion  315 , for example, at least a portion of the interfering portion  315  inserts into the concave  328   a  on one side of the linking member second end  328 , the linking member second end  328  interferes with the first A clamping hook  310 . At this time, the first A clamping hook  310  is located at a position causing the first A insertion hole  131  to be closed, i.e., the first A insertion hole  131  is blocked by the first A clamping hook  310 . According to the embodiment as shown in  FIG. 4B  and  FIG. 5B , when the lock body top surface  202  is pushed by an external force F at a position adjacent to the first side surface  211 , such that the portion of the lock body shell  210  adjacent to the first side surface  211  generates a downward displacement, the first lug  213  pushes to move the first force receiving end  325  to make the force receiving member  321  and the force applying end  326  move toward the linking member first end  327 , hence pushes to move the linking member  322  to that the linking member second end  328  does not abut against the interfering portion  315 . For example, the interfering portion  315  is out of the concave  328   a  (a shown in  FIG. 4A ). At this time, the interfering portion  315  is not interfered and blocked by the linking member second end  328 . Therefore, according to the embodiment as shown in  FIG. 4C  and  FIG. 5C , the elastic member  313  may cause the first A clamping hook  310  to rotate to a position causing the first A insertion hole  131  to be open. 
     In summary, the lockset  900  according to the present disclosure can be opened by only pressing the position of the lock body top surface  202  adjacent to the first side surface  211 , and has better use convenience. The lockset  900  can adopt the embedded design, thereby reducing the probability of damage due to impact on the surface of the box body, and increasing the design flexibility and achieving greater compact and attractive effects. 
     In a preferred embodiment, a pair of insertion holes is disposed in order to match the general use habit of a pair of zipper pullers of a luggage case or to increase the design flexibility. According to the embodiment as shown in  FIG. 3A  and  FIG. 3B , the housing top surface  102  further includes a first B insertion hole  133 , disposed adjacent to the first A insertion hole  131 .
