Description

FIELD OF THE INVENTION

The present invention relates to a locking box for valuables and particularly to a locking box which is mountable onto a counter or table and equipped with a lock to chain valuables to facilitate viewing and wearing and also has a wire wheel to control retraction and releasing of the lock.

BACKGROUND OF THE INVENTION

Conventional jewel locks now on the market generally include a steel chain, a lock and the like. The lock has a connection bar at one end to facilitate fastening of a jewel lock that holds valuables such as jewelries, diamonds, brand name watches and the like to a counter or table by encircling. Thereby the lock can safely latch the desired articles. Such a lock also is widely used in people's daily life and becomes an indispensable household article.

The conventional jewel locks mentioned above accomplish locking by encircling the steel chain over the periphery of the counter or table. The steel chain has connection bars at two ends positioned in a juxtaposed manner to be coupled with a lock. No other function is provided. There are still problems for a jewel lock in practical use, notably:

1. When a conventional jewel lock is in use, the lock is exposed and fastens two ends of a steel chain which encircles the periphery of a counter or table. When customers want to see valuables such as jewelries, diamonds, brand name watches or the like, store staffs fetch the articles requested by the customers and place them on the counter or table to be perused or trial-fitted by the customers. After the customers have made selections, the valuables are returned to the guarded display location. However during perusing or trial fitting pilferage could occur caused by ill intention persons. The conventional jewel lock does not provide adequate theft-preventing function.

2. When the owner or shop keeper is not constantly presented at the display counter or table, or does not pay full attention to the valuables such as jewelries, diamonds, brand name watches or the like while the valuables are not being locked securely, as the conventional jewel lock cannot chain-lock the valuables, those valuables not being locked but displayed on the counter or table could be stolen. It could cause a great loss to the owner or shop keeper.

The wire wheel also can control retraction and releasing of a lock.

To achieve the foregoing object, the locking box of the invention includes at least a wire winding box, a winding control assembly and a lock. The wire winding box has a fastening seat at a lower end that includes an upper fastening disk and a lower fastening disk, a frame at an upper end that has a sliding door and an upper lid. The fastening seat has a directing trough on the periphery of an upper end to be wedged by the frame and a bulging surface that has an opening in the center. There are a wedge trough and an arched notch formed between the directing trough and the bulging surface. The fastening seat also has a lower end with a housing space to hold the upper fastening disk and a plurality of sunken holes formed thereon. The winding control assembly is hinged in the wire winding box and includes a wire wheel, an elastic element and a holding board. The wire wheel has a bottom end with a holding trough formed thereon, a wheel seat with a boss at an upper end and a sealing cap. The elastic element is held in the holding trough. A wire reel is provided and wound on the boss of the wheel seat and has with a detection terminal located at one end. The sealing cap is fastened to the boss of the wheel seat to prevent the wire reel from escaping. The holding board is wedged in the fastening seat to hold the winding control assembly. The lock may be retracted and held in the wire winding box with an opening formed at one end running through by the detection terminal and screwing with a screwing element, and a threading wire at other end to chain-lock the valuables and a connection bar to be latched on or escape a lock core of the lock.

By means of the construction set forth above the following main functions can be achieved: when the lock is used to chain-lock the valuables, the elastic element in the winding control assembly, in cooperation with the pin, can be extended or retracted to control retraction or releasing of the wire reel wound on the wire wheel, and drive synchronously the wire reel on the boss of the wire wheel to control retraction and releasing of the lock.
