Description

[Detailed Description of the Invention] [Technical Field] The present invention provides autobiography (including mopeds and motorcycles)
This relates to a bicycle lock that locks the wheels of a bicycle.

[Background technology] Common locks for bicycles include locks that are fixed to the bicycle's 70 to 7 year old seat stay, and locks that use wire or chains. There is a risk that the key itself may be removed, and there is also a risk that the bicycle may be stolen while it is still locked.

In the latter case, the bicycle can be tied to a structure or tree, so it is impossible for an i-wheel vehicle to be stolen if it is left locked, but the lock can be broken if the wire or chain is cut. Sometimes it happens.

[Purpose of the Invention] The present invention has been made in view of the above points, and its purpose is not only to prevent the bicycle from being stolen while it is locked, but also to prevent the bicycle from being stolen while the bicycle is locked. Our goal is to provide unique bicycle locks that can easily be broken.

[Disclosure of the Invention 1 The present invention provides a base plate that is fixed to a structure or the ground, a base that stands up from the base plate, and a base that is held so as to protrude from the base and is inserted into the rim of a bicycle wheel. the deadbolt, a receiver for receiving the deadbolt tip protruding from the base, a locking means for holding the deadbolt in the protruding state, an unlocking means for releasing the locking means, and a receiving part for receiving the deadbolt tip protruding from the base; the deadbolt is spring-biased in the direction of storage into the base, and the engagement member of the locking means that engages with the deadbolt is spring-biased in the direction of engagement. It is characterized by being fixed to a structure or the ground, and by securing the bicycle with a deadbolt, eliminating the risk of being cut, and furthermore, the operation part can be operated. By simply protruding the deadbolt and holding the deadbolt in this state, in other words, locking is performed.

The present invention will be described in detail below based on the illustrated embodiment. Fixing bolts 10 are provided at both ends of the elongated base plate 1.
By inserting this fixing port 10 into the ground or attaching it to a structure such as a house,
This allows the base plate 1 to be fixed to a structure or the ground. And this base plate 1
On top of the base plate 1, a base 2 and a pedestal 3 are erected at intervals in the longitudinal direction of the base plate 1.
A rotating lever 4 formed in a U-shape and positioned between both sides of the lever 4 is supported by shafts 40, 40 at each end thereof by ring supports 20, 30 at the lower ends of the base 2 and the cradle 3. It is arranged as follows.

As shown in FIG. 2, the base 2 supports a dead bolt 5 therein so that it can slide freely in a direction parallel to the surface of the base plate 1 and can freely protrude toward the pedestal 3 side. This deadbolt 5 is provided with a spring receiver 50 at one end, and has an engagement groove 51 cut into the circumferential surface of the one end, and one end of a wire 53 is connected to the spring receiver 50. There is. The deadbolt 5 is urged in a direction to be housed within the base 2 by a return spring 8 disposed between a support plate 25 and a spring receiver 50 installed within the base 2. The other end of the wire 53 is connected to the rotating lever 4 via boots 1754 and 55.

The locking means for holding the deadbolt 5 in a state protruding from the base 2 is disposed within the base 2 so as to be slidable in a direction orthogonal to the sliding direction of the deadbolt 5, and is inserted into the engagement groove 51 of the deadbolt 5. A lock plate 6 whose tip engages, and a dead pole) 5
The unlocking means is comprised of a shilling lock 7. The plug 701 in the shilling lock 7 is attached so that the arm 71 rotates together with the plug 701.
1 is the engagement stage 61 in the lock plate 6 WII11
When h+ is engaged and 7 is pressed, the lock plate 16 or the dead bolt 5 is disengaged from the engagement state.

A cradle 3 is provided upright from the base plate 1 at a distance that allows the bicycle wheel 9 to be inserted between the pedestal 3 and the pedestal 2. The cradle 3 is a cradle 3 into which the tip of a deadbolt 5 protruding from the base 2 is fitted. It is provided with a hole 31.

However, when it comes to bicycle locks, the normal situation is as shown in Figure 2!
[As shown in FIG. is in a state of To fasten the bicycle, insert the wheel 9 of the bicycle between the base 2 and the cradle 3, and use the wheel 9 to tilt down the rotating lever 4. By collapsing the rotating lever 4, the dead bolt 5 is wire 5
3 to protrude from the base 2, pass through the rim 90 of the wheel 9, and put its tip into the receiving hole 31 of the pedestal 3. Also, at this time, since the engagement groove 51 in the deadbolt 5 reaches the engagement position with the lock plate 6, the spring 6
The lock plate 6, which is biased by 0, causes its tip to engage the engagement groove 51, and holds the dead bolt 5 in this state. In other words, it is locked. The turning lever 4 can be pushed down using the bicycle wheel 9 as described above, or it can also be done by stepping on both sides of the turning lever 4, which are formed as pedals 41. , Schilling - Insert the key into lock 7,
All you have to do is rotate the plug 70. As the plug 70 rotates, the arm 71 pulls down the lock plate 6 against the spring 60 to release it from the deadbolt 5. 5 is returned to its original position under the force of the return spring 8 and is housed in the base 2.

In the above embodiments, the deadbolt 5 is linear and movable in the ring direction, but it may be pivoted at one end and rotatable, or semi-ring shaped and movable in the circumferential direction. The deadbolt 5 can be pressed and driven by the bicycle wheel 9, or can be driven by stepping on it with the foot, as a rubbing part to make the deadbolt 5 protrude from the base 2. Although we have shown things that can be operated using only one method, it is also possible to use only one method.
The structure of the locking means and the unlocking means is not limited to the illustrated example, and the locking means and the unlocking means are not limited to those shown in the figure.
It can also be provided on the pedestal 3 side. The pedestal 3 for receiving the tip of the deadbolt 5 may also be formed integrally with the base 2 instead of being separate and independent from the base 2.

[Effect of the invention 1 As described above, in the present invention, the base plate is fixed to a structure or the ground, so unlike a lock that is attached to a bicycle and prevents the wheel from rotating, it can be left locked. Bicycles will not be stolen in these conditions,
Also, since the deadbolt is used to secure the bicycle, unlike those that use wire or chains, the lock will not be broken by cutting, and simply by operating the operating section, the deadbolt will protrude and lock. Holding the deadbolt in place means that it is locked and can be locked easily, and if you perform an unlocking operation to release the deadbolt from the locking means, the deadbolt can be locked. Since the bolt is spring-biased and returns to its original position, the operation to release the lock is simple.
