A schematic view of an embodiment in which four B-ends are inserted into a groove; and FIG. 4 is a schematic view of a different embodiment of the novel folding lock.

1A to 1C, the folding lock 900 of the present invention includes a lock body 100, a first rod 210, a second rod 220, a third rod 230, and a fourth rod 240. The lock body 100 has a first end surface 101 and a second end surface 102 at opposite ends, and a lock body side 103 between the first end surface 101 and the second end surface 102. The lock body 100 includes a lock core 110 and a groove 120. The lock core 110 is disposed in the lock body 100.

1A to 1C, the groove 120 is disposed on the second end surface 102, extending from the inside to the outside, and forming a groove inlet 121 on the side 103 of the lock body. In other words, the groove 120 is formed inwardly from the edge of the second end face 102 to the second end face 102 and has a groove inlet 121 on the side face 103 of the lock body. In the embodiment shown in FIG. 1A, the recess 120 has a T-shaped cross section, the top of the T-shaped structure is located within the lock body 100, and the bottom of the T-shaped structure is located at the second end surface 102. However, in various embodiments, the cross-section of the groove 120 can be other shapes such as a circle, a triangle, or the like.

1A to 1C, the first rod member 210 has a first A end 211 and a first B end 212 at opposite ends, wherein the first A end 211 is pivotally connected to the first end surface 101. The second rod 220 has a second A end 221 and a second B end 222 at opposite ends, wherein the second A end pivot 221 is connected to the first B end 212. The third rod 230 has a third A end 231 and a third B end 232 at opposite ends, wherein the third A end 231 is pivotally connected to the second B end 222. The fourth rod 240 has a fourth A end 241 and a fourth B end 242 at opposite ends, wherein the fourth A end 241 is pivotally connected to the third B end 232, and the fourth B end 242 can be inserted into the recess by the groove inlet 121. The slot 120 is locked by the lock core 110.

The folding lock 900 of the present invention further includes the embodiment shown in FIGS. 1A to 1C. The rod connector 290 is connected to the second B end 222 and the third A end 231 respectively. In other words, the second rod 220 and the third rod 230 are pivotally connected to each other by the second B end 222 and the third A end 231 to the rod connecting member 290. However, in different embodiments, the second B end 222 and the third A end 231 can be directly pivoted without passing through the rod connector 290. When the fourth B-end 242 is inserted into the recess 120, the lever connector 290 is adjacent to the lock body side 103.

The first rod 210, the second rod 220, the third rod 230, and the fourth rod 240 are respectively rotatable relative to the extending direction of the axis 401 passing through opposite ends of the lock body 100. In other words, as in the embodiment illustrated in FIGS. 1B and 1C, the first rod 210, the second rod 220, the third rod 230, and the fourth rod 240 can be rotated in the same or opposite directions of the direction 402. Viewed at different angles, the first rod 210, the second rod 220, the third rod 230, and the fourth rod 240 are respectively rotated on different planes that are parallel to each other and perpendicular to the axis 401.

The length of the first rod 210 of the L-member ₂₁₀ and the fourth longitudinal member 240 of the L-bar ₂₄₀ the same, the length of the second rod 220 of the L-member ₂₂₀ and third member 230 of length L bar ₂₃₀ the same length of the first lever member 210 of L _{210 is} greater than the length L _{220 of the} second rod ₂₂₀ . When the fourth B end 242 is inserted into the groove 120, the first rod 210, the second rod 220, the third rod 230, and the fourth rod 240 may be parallel to each other. Viewed from different angles, the first rod 210 and the fourth rod 240 of the same length may be regarded as one set, and the second rod 220 and the third rod 230 of the same length may be regarded as another group on the inner side thereof. Since the length of the inner two rods 220, 230 is smaller than the outer two rods 210, 240, when the fourth B end 242 is inserted into the groove 120, the inner two rods 220, 230 can be combined with the outer two rods 210, 240 parallel. Based on the above, the folding lock 900 of the present invention can reduce the storage volume, thereby solving the problems described in the prior art.

The manner in which the novel folding lock 900 is used is further explained below.

2A to 2C, the first rod 210, the second rod 220, the third rod 230, and the fourth rod 240 are rotatable and pulled away from the lock body 100 by the user. Into the object you want to lock (for example, the pedal wheel frame). Then, as in the embodiment shown in FIGS. 3A to 3C, the fourth B-end 242 is inserted into the groove 120 by the groove inlet 121, and the fourth B-end 242 is restricted from the groove inlet 121 by the lock core 110.

More specifically, the lock core 110 may have elements such as a lock shaft. When the lock core 110 is in an unlocked state, for example, the user inserts the keyhole 150 into the keyhole, or the combination lock After the lock cylinder is unlocked by the user, the lock shaft can move within the lock body 100. When the lock core 110 is in the locked state, the movement of the lock shaft in the lock body 100 is restricted. The construction of the above locks is a matter of fact, and will not be repeated here. When the fourth B end 242 is inserted into the groove inlet 121, the lock shaft of the lock core 110 can be restrained from the groove inlet 121 by engaging the lock shaft of the lock core 110, thereby achieving the purpose of locking. However, in various embodiments, the fourth B-end 242 can be provided with a locating hole, or a ring or hook for the lock shaft to be inserted. On the other hand, if the lock is to be unlocked, the lock core 110 only needs to be unlocked, the movement limit of the lock shaft is released, the lock shaft can be separated from the fourth B end 242, and the fourth B end 242 can be disengaged from the groove 120. Unlock the lock. The folding lock 900 can also be provided with an operating member 140 for operating the locking core 110 to engage with the fourth B end 242.

In the foregoing embodiment, the folding lock 900 includes a first lever 210, a second lever 220, a third lever 230, and a fourth lever 240. However, in various embodiments, the fold lock can increase the number of bars depending on manufacturing, design, or use requirements. Further, more levers can increase the overall length of the deployed pivotally spaced members, allowing the folding lock to lock the object to a larger object, such as a support column of a building.

More specifically, as shown in the embodiment of FIG. 4, the folding lock 900 includes a lock body 100 and a plurality of rod members 200 that are pivotally connected to each other. The lock body 100 has a first end surface at opposite ends and a second end surface 102, and a lock body side 103 between the first end surface 101 and the second end surface 102. The lock body 100 includes a lock core 110 and a groove 120. The lock core 110 is disposed in the lock body 100. The groove 120 is disposed on the second end surface 102 and extends from the inside to the outside, and forms a groove inlet 121 on the side of the lock body 103. The plurality of bars 200 are the same length, the shorter length bars 200 are located between the longer length bars 200, and one of the longest lengths of the plurality of bars 200 (200') The first end face 101 is pivotally connected to the first end face 101, and the other (200") can be inserted into the groove 120 by the groove inlet 121, and can be locked by the lock core 110.

As with the embodiment shown in Figure 4, when the other (200") of the plurality of bars 200 is inserted into the recess 120, the plurality of bars 200 can be parallel to each other.

In the embodiment shown in FIG. 4, the groove 120 has a T-shaped cross section, the top of the T-shaped structure is located in the lock body 100, and the bottom of the T-shaped structure is located on the second end surface 102. However, in various embodiments, the cross-section of the groove 120 can be other shapes such as a circle, a triangle, or the like.

As shown in the embodiment of Figure 4, the folding lock 900 further comprises a lever connector 290, the two ends of the rod connecting member 290 are respectively pivotally connected to the two shortest rod members of the plurality of rod members 200. However, in various embodiments, the two bars of the plurality of bars 200 having the shortest length can be directly pivoted without passing through the bar connector 290.
