Abstract

<P>PROBLEM TO BE SOLVED: To provide a lock of an attache case simple in structure and handling. <P>SOLUTION: A central operating part 30 in the lock 20 is composed of a combined body of an upper lever 31 and a lower lever 32 fitted to a lever holder 34, a cam plate 33 engaged with the lower lever 32, a right link 24 fitted to the cam plate, and a left link 25. Movement of the right and left links 24, 25 are inhibited or released by operating a numeral board 41 of a dial lock 40 mounted on the operating part 30. A slider 50 engaged with a locking piece mounted on a lid of a case is interposed between the tips of the links 24, 25. This lock can lock and unlock the case only by operating the dial lock 40 and the combined body of the levers 31, 32. <P>COPYRIGHT: (C)2004,JPO

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a lock that is convenient for use in an attache case or the like.
[0002]
[Prior art and problems]
Conventional bag locks have a center lock and side locks on both sides.The center lock is unlocked with a key, etc., the side lock can be released, and the lid is opened in the order of opening the side lock. The structure and operation of the lock were complicated.
[0003]
Therefore, a lock that can be easily operated on an attache case or the like and can be opened and closed with one touch without using keys or the like is desired.
[0004]
[Means for Solving the Problems]
Therefore, in this invention, in order to solve the above-mentioned problem, a slider which also serves as an engaging body with a locking hook attached to a case lid comes into contact with a tip of a link extending left and right from an operation unit attached to the case body. A lock of an attache case is provided, wherein the lock is provided so as to prevent or release the movement of the link by a dial lock attached to the operation unit in the case body.
[0005]
【Example】
FIG. 1 is a perspective view of an attache case 10 having a lock of the present invention, FIG. 2 is a perspective view showing a state where a lid is opened, 1 is a case main body, 2 is a lid, 20 is a lock of the present invention, and 30 is a lock. The lock operation unit 40 is a dial lock. Reference numeral 22 denotes a lock center cover, and reference numeral 23 denotes a side cover. Further, reference numeral 3 denotes a locking hook attached to the lid 2, and 4 denotes a handle attached to the main body 1.
[0006]
3 is a front view showing the lock 20 taken out, FIG. 4 is a top view, FIG. 5 is a cross-sectional view showing an internal mechanism, and FIG. 6 is a relationship between the lock and the lock hook of the lid viewed from the front. FIG.
[0007]
The lock 20 includes an outer box 21, a center cover 22 in the center, side covers 23 on both sides, an operation unit 30 provided in the center, a dial lock 40, and the like. The outer box 21, the covers 22, 23 are attached with the outer skin 11 of the case therebetween.
[0008]
In the operation unit 30, an upper lever 31 and a lower lever 32 are combined and attached to a lever holder. FIG. 10 is a perspective view of the upper lever 31, FIG. 11 is a perspective view of the lower lever 32, and FIG. 12 is a perspective view of the lever holder 34. Reference numeral 35 denotes a holding plate for attaching the combination of the upper and lower levers to the holder 34; 37, an operation piece for operating the combination of the levers 31 and 32; and 39, a rotation axis of the lever combination. FIG. 7 is a cross-sectional view taken along the line AA of FIG. 5. As can be seen from FIGS. 5, 7, 11, etc., a cam groove 38 is formed in the lower lever 32, and the groove 38 and the cam plate 33 are Is engaged.
[0009]
If the upper lever 31 is rotated by putting a finger on the operation piece 37 of the upper lever 31, the lower lever 32 combined with the upper lever simultaneously rotates and engages with the cam groove 38 of the lower lever 32. The two cam plates 33 move in opposite directions. Further, a right link 24 and a left link 25 are connected to each of the cam plates 33, and move in opposite directions together with the cam plates 33. In FIG. 12, reference numeral 36 denotes a hole through which the engaging portion of the cam plate 33 projects to engage with the cam groove 38.
[0010]
The dial lock 40 has an arbitrary number of numeral dials (three in the illustrated example) 41, and is used to prevent movement of the left and right links 24, 25 (locked state) or to enable or disable the movement of the left and right links 24, 25 using a predetermined password. (When unlocked).
[0011]
A slider 50 is interposed in contact with the tips of the left and right links 24 and 25. FIG. 8 is a perspective view of the slider 50, and FIG. 9 is a bottom view of FIG. 8 as viewed in the direction D. Reference numeral 51 denotes an engagement portion with the locking hook 3 attached to the lid 2 of the case; It is a hole for the hook 3 to enter into the slider 3 when it is pressed.
[0012]
In the illustrated embodiment, when the attache case is locked, the cam 33, the left and right links 24, 25, and the slider 50 are all close to the center, and the locking hook 3 attached to the lid 2 as shown in FIG. Are engaged with the locking portions 51 through the holes 52 of the slider 50. (As a concrete structure, if the link and the slider are integrated or combined, the structure becomes complicated. Therefore, springs are arranged at both ends of the outer box 21 and the slider is urged toward the center. Is considered.)
[0013]
When opening the cover 2 of the attache case 10, the user operates the dial lock 40 with a predetermined password to release the left and right links 24 and 25 from being blocked. (The mechanism related to the dial lock is a well-known technique and has no direct relation to the gist of the present invention, so detailed description is omitted.) When the lever 31 is turned, the lower lever 32 combined with the upper lever 31 also turns in the same direction.
[0014]
Then, the cam plates 33 engaged with the cam grooves 38 of the lower lever 32 move outwardly along the respective cam grooves. The right link 24 connected to each of the cam plates moves to the right, and the left link 25 moves to the left. Each link then pushes the corresponding slider 50 outward. (That is, in FIG. 6, the right link 24 pushes the slider 50 to the right.) Therefore, in the left and right sliders 50, the engagement between the locking hook 3 of the lid 2 and the engaging portion 51 of the slider 50 is released. The lid 2 can be opened.
[0015]
When the lid is closed, when the lid is closed, the locking hook 3 is pushed into the slider 50, so that the temporary slider 50 also moves outward (ie, rightward in FIG. 6), and returns to the original position to move the slider 50 back. The engaging portion 51 and the locking hook 3 of the lid 2 are engaged, and a locked state is established. At that time, only the slider 50 slides. If the dial of the dial lock 40 is appropriately rotated to prevent the movement of the left and right links 24 and 25, the operation piece 37 cannot be moved, and a complete locked state is obtained.
[0016]
【The invention's effect】
The lock of the attache case of the present invention is configured as described above, and the lock of the attache case can be unlocked in one operation by using a dial lock and rotating the operation piece of the central operation unit with a finger. it can.
