[0013]
Two closing plates 60 are provided, each having one stopper 61, and the two closing plates are accommodated in the elongated recesses 212 of the upper member, and the stoppers are elongated slots 213 of the elongated recesses. The two closure plates, which are inserted into the threads of the transmission shaft rotating part through the same, also have a notch, as shown in FIG. 62 are provided.
[0014]
One sign board 70 is accommodated in the guide groove 25, and a sign indicating an open / closed state is provided on the front face of the sign board. "LOCK" and "OPEN" of group B, and one convex pillar 71 is provided on the rear surface of the sign plate, and is inserted into the screw thread 32 of the transmission shaft rotating part.
[0015]
One locking member 80 has an elongated shape, one receiving portion 81 is provided on each side, and a small gear 82 is provided on the bottom surface of one receiving portion, and the same as the gear. Similarly, a small number of receiving holes 83 are provided at positions corresponding to the receiving holes of the lower member lateral recess 223 between the two receiving portions on the surface, and another one surface of the locking member is provided. Is provided with one depression 84 so that a key can be inserted. The locking member is housed in the lateral recess, the two receiving portions are respectively located in the two sliding grooves 224, and the receiving portion having the gear has a through hole. The gear is located in the sliding groove so that the gear meshes with the convex teeth 42 on the outer periphery of the locking ring.
[0016]
One elastic component 90 is provided between the stopper 226 of the lateral concave sliding groove and the end face of the one receiving part 226 of the locking member, and the elastic member separates the locking member from the stopper. Hold position. In this embodiment, the elastic component is a single spring, but may be a component having a similar effect, such as a single leaf spring or a single rubber.
[0017]
One bottom plate 100 covers the bottom surface of the lower member 22, the locking member 80 is sandwiched between the bottom plate and the lower member lateral recess 223, and the depression of the locking member defines one key insertion hole 101. To form.
[0018]
With the above-described structure, the entire operation when the present embodiment is used is as follows. When the user inserts the key of the magnet (combination of the key of the magnet and the magnetic body is a conventional technique and will not be described in detail here), the user can insert the key into the recess 84 and release the locking member. Press and move along the sliding groove. With the movement of the locking member, the locking member meshes the gear with the convex teeth of the locking ring, rotates the locking ring, and the locking ring rotates the transmission shaft of the transmission shaft by the oblique convex teeth. The rotating parts are interlocked to rotate the transmission shaft accordingly, and the two closing plates are inserted into the threads of the two rotating parts by the stopper parts, so that the rotation of the transmission shaft Thereby, the two closing plates are guided by the thread and move relatively closer or farther apart in the elongated recess, and at the same time, the screw thread also moves the indicating plate into the guiding groove. Guide them together and move them back and forth. When the user releases the pressure on the key, the resilient component regains elasticity and returns the locking member to its normal position, causing the locking ring to rotate in the opposite direction, but at this time, the locking ring Do not rotate the transmission shaft in conjunction with it.
[0019]
For example, as shown in FIG. 4, when the two closing plates are in the relatively close closing position, the character shape shown in the signing window D outside the signing plate is A set of "LOCK". is there. The user inserts the key and pushes the locking member, interlockingly rotating the transmission shaft by 90 degrees, the screw thread guiding the two closure plates, and relative to each other as shown in FIG. It can be moved to a remote open position. At the same time, the sign board is moved to the left along the guide groove, so that a B-shaped “OPEN” character appears in the sign window D.
[0020]
Thereafter, the suitcase is closed, and the T-shaped key piece L on the lid of the suitcase is inserted into the keyhole, and then the user simply presses the key again, and the locking member is interlocked to operate. It is possible to rotate the transmission shaft again by 90 degrees. At this time, the two closing plates return from the open position to the closing position again, the sign plate also moves to the right again, returns to the previous operation position, and a "LOCK" character appears in the sign window. The T-shaped key piece is locked in the keyhole to achieve the purpose of locking.
[0021]
In addition to the above-mentioned use state, as shown in FIGS. 10 to 12, in this embodiment, one connecting component 120 is further provided at each of two receiving grooves on the rear side surface of the main body. A single convex pillar 121 is provided on each connecting part, and is similarly inserted into the thread 32 of the rotating part through the slot 24 so that the two threads are formed when the rotating part rotates. To guide and move the connecting parts. Thereafter, the main body is placed in one case 122, and the two connecting parts are connected to one connecting rod set 123, respectively, as shown in FIG. It extends to 124.
[0022]
At the time of use operation, the user similarly inserts the key into the key insertion hole, presses the locking member with the key, and rotates the locking ring and the transmission shaft in conjunction with each other. At this time, the two closing plates and the sign plate perform the same operation as described above. At the same time, when the two closing plates approach each other (closed position) due to the guidance of the two rotating part threads, the two connecting parts also protrude toward both ends as shown in FIG. The connecting rod, which is extended and connected to the connecting part, is locked in the keyhole 125 of the side lock, thereby achieving the operation of locking the center and the side simultaneously. When the user presses the key again, the two closing plates return to the open position, and the two connecting parts also return inward at the same time as shown in FIG. Pulling out and opening the center and side at the same time.
[0023]
In addition, when the present embodiment is actually used, various combinations in use can be selected, and the manufacturer may use the combination by himself. For example, if only the connecting component is installed without installing the closing plate, it is possible to provide the user with a function that the side locks at both ends can be simultaneously controlled from the center. As a result, the structure of the present embodiment can reliably achieve the object of the present invention.
