[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-46743 Summary of the Invention [Problem to be solved by the invention]

[0005] When it is desired to temporarily fasten the connector of Patent Document 1 to a string-like object, such as a rope, while the object is suspended, the connector is opened against the elasticity of the opening / closing body and then the string-like object is passed through. When it is desired to remove the connector from the string-like object, the connector is opened again against the elasticity of the opening / closing body and then removed.

[0006] Thus, when it is desired to temporarily hang the connector of Patent Document 1 on a string-like body, it is necessary to operate the opening and closing part each time, which is troublesome.

[0007] SUMMARY OF THE INVENTION An object of the present invention is to provide a fastening device that can solve the above-mentioned problems and can have one or two hook portions depending on the application. [Means for solving the problem]

[0008] In order to achieve the above-mentioned object, the locking device of the present invention is a locking device that can be opened, closed, or rotated via an axis portion and is composed of a first frame portion and a second frame portion that are integrated by overlapping, and the first and second frame portions have a pair of first and second base portions that form part of the axis portion, and first and second hook portions that have approximately the same hook-like shape and extend from one end of the first and second base portions, and a locking piece portion is attached to the other end of the first base portion, and the tip portion of the locking piece portion can abut against the first locking piece abutment portion at the tip of the first hook portion. [Effects of the Invention]

[0009] In this way, the locking device of the present invention is normally used in the form of a hook body in which the first and second frame portions overlap and are integrated, and when a locking body is locked to this hook body and then locked to another locking body, the first and second frame portions can be separated, and one locking body can be hung on the first frame portion and the second frame portion can be locked to the other locking body.

[0010] By engaging the first and second frame portions, respectively, one engaging body does not come into contact with the other engaging body, and therefore one or the other engaging body can be easily removed from the first and second frame portions and attached without interfering with the other.

[0012] The present invention will be described in detail below based on the illustrated embodiments. [Example]

[0013] FIG. 1 is an exploded perspective view of the locking device. The locking device is mainly made of hard synthetic resin or metal such as aluminum, and is approximately 5cm wide, 10cm long and 1cm thick. The size of the locking device can be selected appropriately depending on the application, and metals that are resistant to deformation and breakage due to the weight of the hanging object can be used.

[0014] The locking device is composed of a first frame portion 1 and a second frame portion 2, which are connected via a shaft portion 3 so as to be able to open and close freely.

[0015] The first and second frame portions 1, 2 have first and second base portions 1a, 2a that form the shaft portion 3 on the lateral side of the underside, and first and second hook portions 1c, 2c that extend upward from one longitudinal end 1b, 2b of these first and second base portions 1a, 2a, respectively, and have an inverted J-shaped hooked shape.

[0016] The shaft portion 3 is composed of a first rotating piece 1d of the first base portion 1a, a second rotating piece 2d of the second base portion 2a with which the first rotating piece 1d is combined, and an axial rod 3a that is inserted and fixed into a first insertion hole 1e provided in the first rotating piece 1d and a second insertion hole 2e provided in the second rotating piece 2d.

[0017] The first and second hook portions 1c, 2c, which have approximately the same shape, are composed of first and second apexes 1f, 2f, first and second main pillar portions 1g, 2g that hang down from one end of these first and second apexes 1f, 2f and connect to one end 1b, 2b of the first and second base portions 1a, 2a, and first and second sub-pillar portions 1h, 2h that hang down from the other ends of the first and second apexes 1f, 2f.

[0018] The opposing first and second hook portions 1c and 2c have first and second mating portions 1i and 2i on their inner surfaces, respectively. In Fig. 2, the first mating portion 1i has a protruding shape, and the second mating portion 2i has a recessed shape that fits into this protruding shape.

[0019] The engagement of the first and second fitting portions 1i and 2i maintains the closed state of the first and second frame portions 1 and 2. The engagement of the first and second fitting portions 1i and 2i can be released by applying a slight force in the opening direction of the first and second hook portions 1c and 2c.

[0020] The concave and convex shapes of the first and second fitting portions may be reversed, and any appropriate shape may be adopted as long as the first and second closed states can be maintained. Furthermore, it is also possible to appropriately arrange one or more sets of first and second fitting portions 1i, 2i at any positions on the opposing inner surfaces of the first and second hook portions 1c, 2c.

[0021] The lower end of the first sub-pillar 1h, i.e., the tip of the first hook 1c, is provided with a lock piece abutment 1j against which the tip 4a of the lock piece 4, described below, abuts. This lock piece abutment 1j is composed of a recess 1k provided on the side surface of the first sub-pillar 1h facing the first main pillar 1g, and a protruding piece 1l located below this recess 1k, i.e., at the very tip of the first hook 1c, which protrudes toward the first main pillar 1g and bulges in the thickness direction of the first hook 1c.

[0022] The recess 1k and the protrusion 1l make it difficult for the tip of the first hook 1c to come off, but they are not necessarily provided. Furthermore, a second locking piece abutment can also be disposed at the lower end of the second sub-pillar 2h, i.e., at the tip of the second hook 2c, and a recess can also be provided in this second locking piece abutment (not shown).

[0023] The other end 1m of the first base 1a bulges in the thickness direction of the first hook portion 1c, similar to the convex piece portion 1l, and bearing holes 1n and 1o are drilled on the front and back surfaces directly above the lower first pivot piece portion 1d, into which the shaft pin 4b of the lock piece portion 4 can be inserted.

[0024] The shaft rod 3a, which is the central axis of the shaft portion 3, is formed along the longitudinal direction of the first and second base portions 1a and 2a, and the shaft portion 3 is formed on the side surfaces of the first and second base portions 1a and 2a. The first and second frame portions 1 and 2 can be opened and closed via the shaft portion 3.

[0025] The lock piece 4 is formed from a bent metal strip, with the tip 4a bent in a U-shape, and a pair of opposing shaft pins 4b at the lower end being slightly offset from each other.

[0026] When assembling the locking device, the first and second rotating pieces 1d and 2d that mesh with each other are combined, and then the shaft rod 3a is inserted through the first and second insertion holes 1e and 2e.

[0027] In this way, the shaft portion 3 is completed, which allows the first and second frame portions 1 and 2 to be opened and closed. Next, the pair of shaft pins 4b of the locking piece portion 4 are inserted into the bearing holes 1n and 1o of the first base portion 1a, respectively, to complete the assembly of the locking device.

[0028] Figure 2 is a perspective view from the front of the device when the shaft portion 3 is closed after assembly, i.e., when the first and second fitting portions 1i and 2i are fitted together to form the first and second frame portions 1 and 2, respectively, and Figure 3 is a perspective view from the rear.

[0029] Figure 4 is a perspective view from the front of the shaft portion 3 in an open state, i.e., with the first and second fitting portions separated and the first and second main pillar portions 1g and 2g arranged in a straight line, and Figure 5 is a perspective view from the rear.

[0030] The locking piece 4 has a pair of shaft pins 4b that are slightly offset, so when the locking piece 4 is supported in the bearing holes 1n and 1o, an outward biasing force is generated, which maintains the locked state in which the locking piece 4 and the locking piece abutment portion 1j are constantly in contact with each other.

[0031] By pressing the lock piece 4 attached to the other end 1m of the first base 1a from the outside against the biasing force, the locked state in which the lock piece 4 abuts against the lock piece abutment portion 1j is released.

[0032] When using the locking device, depending on the application, it is possible to select either a state in which the first and second frame portions 1 and 2 are integrated into a hook body 5 as shown in Figures 2 and 3, or a state in which the hook body 5 is separated into the first and second frame portions 1 and 2 as shown in Figures 4 and 5.

[0033] For example, when simply hanging the locking device on the belt of a bag or the like, the locking device is used in the form of a hook body 5 in which the first and second frame portions 1 and 2 are integrated, and in this case, as described above, the locked state of the lock piece portion 4 is released and the belt, which is the locking body, is inserted into the hook body 5.

[0034] In this way, when it is desired to hang a locking device attached to a locking body such as a bag on another locking body such as a hanger hook, the hook body 5, in which the first and second engaging portions 1i and 2i are engaged, is pulled outward from both sides to separate the first and second hook portions 1c and 2c.

[0035] The first and second main pillars 1g and 2g are opened and arranged in a straight line via the shaft portion 3, as shown in Figures 4 and 5. Then, by engaging the second hook portion 2c with the hanger hook, the bag can be locked to the hanger hook via the locking device.

[0036] This procedure for opening the shaft portion 3 can be performed while the bag belt is hanging from the locking device, without operating the lock piece 4. If a second lock piece abutment portion with a recess is provided at the tip of the second hook portion 2c and the protrusion portion 11 is omitted from the tip of the first hook portion 1c, the first and second hook portions 1c and 2c can be separated by pressing the lock piece 4.

[0037] In this way, when the second lock piece abutment portion is provided, the first and second hook portions 1c, 2c cannot be separated unless the lock piece portion 4 is pressed, so there is no need to provide the first and second fitting portions 1i, 2i.

[0038] After the second hook portion 2c is engaged with the hanger hook, the first and second hook portions 1c and 2c are closed to return to the state of the integrated hook body 5. [Example]

[0039] Figure 6 is a perspective view of the locking device of Example 2 as seen from the front before the shaft portion 3' is rotated, and Figure 7 is a perspective view of the locking device of Example 2 as seen from the front after the shaft portion 3' is rotated.

[0040] The difference between the locking device of Example 2 and the locking device of Example 1 is that the shaft rod 3a, which is the central axis of the shaft portion 3 of Example 1, is formed along the longitudinal direction of the first and second base portions 1a and 2a, whereas the central axis 3a' of the shaft portion 3' of the locking device of Example 2 is formed along the thickness direction of the first and second base portions 1a and 2a.

[0041] The first and second frame portions 1 and 2 of Example 2 are rotatable via the shaft portion 3', and the state in which the first and second fitting portions 1i and 2i are integrated into the hook body 5 shown in Figure 6 can be changed to a state in which the first and second hook portions 1c and 2c are separated.

[0042] Then, the first and second hook portions 1c, 2c are rotated around the shaft portion 3' until the first and second main pillar portions 1g, 2g are straightened, resulting in the state shown in FIG.

[0043] Furthermore, in the locking device of Example 1, the integrated state of the first and second frame portions 1, 2 is maintained by the engagement of the opposing first and second engaging portions 1i, 2i, whereas in the locking device of Example 2, the integrated state is maintained by the first engaging portion 1i' that slides and engages from the side and the second engaging portion provided on the second frame portion 2 (not shown).

[0044] Like the locking device of Example 1, the locking device of Example 2 can also be used to rotate the shaft portion 3' without operating the lock piece portion 4, and the second hook portion 2c can be hung from another locking body, such as a hanger hook, while the belt of a bag is still hanging from the locking device, and therefore functions in the same way as the locking device of Example 1.

[0045] In this way, the locking device of the present invention is normally used in the state where the first and second frame portions 1, 2 are overlapped and integrated to form the hook body 5, and when a locking body is locked to this hook body 5 and then locked to another locking body, the first and second frame portions 1, 2 can be separated, and one locking body can be locked to the first frame portion 1 and the other locking body can be locked to the second frame portion 2.

[0046] By engaging the first and second frame parts 1 and 2, respectively, one engaging body does not come into contact with the other engaging body, and therefore one or the other engaging body can be easily removed from the first and second frame parts 1 and 2 and attached without interfering with each other.
