About.

Conventionally, a circle lock attached to a bicycle body or the like is attached to a stay or the like which is a bicycle body, and an arc-shaped bag stored in the bag storage tube portion of the circle lock is moved to an unlocked position and a locked position. By moving the bag between the two, the hook is intruded or retracted between the spokes of the wheel to lock or unlock. In order to move the arc-shaped hook between the unlocking position and the locking position, the operation knob fixed to the hook is operated to move the arc-shaped hook from the unlocking position and the locking position of the hook within the circle lock. It is necessary to open it, and the heel is released from the unlocked position and the locked position by the operation knob, and the heel is manually moved to the unlocked position or the locked position in the circle lock, and the positions are unlocked. It was maintained by a lock locking mechanism or a locking mechanism.

In addition, it is bothersome and troublesome to open the bag from the unlocked position and the locked position by operating the operation knob, and manually move the bag to the unlocked position or the locked position in the circle lock. The lock is always urged to the unlocked position by spring bias etc. so that the heel is released from the locked position automatically upon returning from the locking mechanism to the unlocked position. Some have been proposed to be housed in the bag storage tube. In the structure like this,
The urging force urged toward the release position by operating the operation knob fixed to the heel at the unlocking position with the heel automatically returned to the unlocking position with the unlocking operation of the locking mechanism It is only necessary to manually move the scissors to the locking position side against this, and the movement of the scissors from the locking position to the unlocking position is automatically performed in accordance with the unlocking operation of the locking mechanism. Became possible.

As a combination of such a manual movement of the bag to the locking position and an automatic return of the bag by the unlocking operation of the locking mechanism, the bicycle as described in Patent Documents 1 and 2 below There is a lock. A bicycle lock as a first conventional example described in the following Patent Document 1 will be described with reference to FIG. 3. As shown in FIG. 3A, in the circle lock A attached to the rear fork H 1 or the like of the vehicle body. The stored heel A ′ is the push button 12 in the operation knob 106 fixed to the heel A ′.

In such a bicycle circle lock, in the bicycle lock of the first conventional example described in Patent Document 1 shown in FIG. 3, the front wheel is interlocked with the locking operation of the circle lock A on the rear wheel side. Although the side box lock B is locked and secure locking is possible, the push button 126 in the operation knob 106 for operating the circle lock A to the locking position side is moved upward from the head of the operation knob 106. Since it is configured to project, the push button 12 of the operation knob 106 that is in the unlocked position during traveling is used.
6 is pushed by the lower part of the bag or the like carried by the passenger, so that the bag A 'may enter between the spokes, leading to an unexpected situation such as a wheel lock.

Further, in the bicycle lock of the second conventional example described in Patent Document 2 shown in FIG. 4, the opening operation of the bag to the locking position is performed by pressing the push button 204 in the locking operation knob 202. , Because the top of the push button 204 is configured below the same position as the top of the unlocking operation knob 202,
As in the first conventional example, there is no possibility that the push button 204 is pressed by the lower part of the bag or the like carried by the occupant and the bag is reluctant to cause an unexpected situation such as a wheel lock.

However, both of the first conventional example and the second conventional example have a relatively small push button and are inferior in operability within the locking operation knob, and in particular, can suppress the swaying of the push button within the locking operation knob. Further, the operability was inferior. Moreover, since the push button is small, it has been difficult to perform a reliable operation.

Accordingly, the present invention provides a circle lock that solves the above-described problems of the conventional circle lock and does not cause the push button reluctance in the operation knob for locking, and enables reliable operation with excellent operability. For the purpose.

For this reason, the present invention is a circle lock that is attached to a bicycle body, etc., and is a circle lock that is housed in a bag storage tube portion of the circle lock so as to be movable between an upper unlocking position and a lower locking position. The arc-shaped hook is allowed to open in the hook storage tube portion by a downward pressing operation of a push button of a locking operation knob fixed to the hook, and the locking is performed at the lock position of the hook. In the circle lock having a locking mechanism for maintaining the locking mechanism, the top of the push button that moves in the vertical pressing direction with respect to the locking knob is configured below the top position of the locking knob, and the operation surface of the push button is pressed characterized by being configured in a shape leaving locking operation hysterectomy Mika et al in the direction. Further, the present invention is characterized in that a reinforcing rib connects the operation surface portion of the push button and the vertical operation portion formed in the pressing direction. Further, the present invention is characterized in that non-slip irregularities are formed on the operation surface portion of the push button, and these are means for solving the problems.

According to the present invention, there is provided a circle lock attached to a bicycle body or the like, which is a constituent element according to claim 1, and an upper unlocking position and a lower locking position in the bag storage tube portion of the circle lock. The arc-shaped scissors that are movably stored between the scissors can be opened by the pressing operation of the push button of the locking operation knob fixed to the scissors. In a circle lock having a locking mechanism for maintaining the locking at the locking position of the hook, the top of the push button that moves in the vertical pressing direction with respect to the locking operation knob is configured below the top position of the locking operation knob. with the operating surface of the push button, from that configured in the shape away locking operation hysterectomy Mika et towards the pressing direction, even no possibility of acting blindly push button in locking operation knob by bag like the rider carries Imprisonment Not, since exhibits locking operation hysterectomy Mika et away shape toward the pressing direction, it is possible to operate a secure push button with excellent operability.

Further, when the reinforcing surface is connected between the operation surface portion of the push button and the upper and lower operation portions formed in the pressing direction, which is a constituent requirement according to claim 2, the locking operation knob main body is directed toward the pressing direction. By presenting a shape away from the portion, even if a slightly large moment force or the like acts on the operation surface portion of the push button, the pressing force can be reliably transmitted to the vertical operation portion due to the presence of the reinforcing rib. Furthermore, when the non-slip unevenness is formed on the operation surface portion of the push button, which is a constituent requirement of the third aspect, the push button can be reliably operated without slipping even in rainy weather.

It is the whole perspective view of the circle lock of this invention, and the whole front view by which illustration of the locking operation knob was abbreviate | omitted.

1 and 2 show a first embodiment of the circle lock of the present invention. As shown in FIG.
The circle lock 1 attached to the body of the bicycle, for example, the rear hawk by the attaching portions 7 and 7,
A main body is formed in the shape of an arc and a horseshoe, and is not shown along the main body (see FIG. 3A of the conventional example).
1C) is formed. A bag storage tube portion 1C for storing the bag of the same structure as A ′ of FIG. An arc groove 3 is formed on the surface side of the rod storage tube portion 1C, and an unlocking locking notch portion 3A is formed at the unlocking position (upper side) of the arc groove 3 (FIG. 1B). . Although not shown, when the scissors move from the unlocking position to the locking position, as shown in FIG. The pad 1 is extended from the heel protrusion side 1A to the heel receiving side 1B in the heel storage tube 1C.

In the locking position of the heel, the locking position of the heel is maintained by a lock mechanism or the like that moves forward from the locking mechanism of the locking mechanism 5 to the locking notch or the like at the locking position of the heel. Locking mechanism 5
When the key 6 is inserted and unlocked, the lock of the bag is released. For example, the hook biased in the opening direction by the insertion of a restoring spring or the like automatically moves to the unlocked position together with the lock operation knob 2. Can be restored. If the rod is not provided with a restoring spring or the like and is not urged in the opening direction, the key 6 is inserted into the locking mechanism 5 to perform the unlocking operation, and then the locking operation knob 2 is picked and released. It is only necessary to manually move the scissors to the lock position.

As described above, in order to move the scissors from the upper unlocking position to the lower locking position, the push button 4 in the locking operation knob 2 is pressed downward (the center side of the circle lock 1 with respect to the locking operation knob 2). The locking operation knob 2 needs to be released from the unlocking notch 3A of the arc groove 3 and released.
As shown in an enlarged perspective view in FIG. 2, the locking operation knob 2 is configured as follows.
As shown in FIG. 2 (A), the push button 4 accommodated in the main body of the locking operation knob 2 so as to be movable up and down (in the radial direction connecting the center of the circle lock 1 with respect to the locking operation knob 2) has a top portion 4A. It is configured below the position of the top portion 2A of the locking operation knob 2, and the operation surface portion 4C of the push button 4 is moved in the pressing direction (the arrow direction of the push button pressing direction display portion 2C provided on the front wall portion 2B of the locking operation knob 2). ), The locking operation knob 2 is configured to be separated from the main body.

In the example shown in the figure, the operation surface portion 4C is formed in a circular arc surface that is concave on the outside, and a non-slip unevenness is formed on the surface, so that the push button can be operated reliably without slipping even in rainy weather. I have to. As is well understood in the rear view of FIG. 2B, the operation surface portion 4C of the push button 4 and the vertical operation portion 4B formed in the pressing direction are connected by a reinforcing rib 4D, and in the pressing direction. Even when a slightly large moment force or the like is applied to the operation surface portion 4C of the push button 4 that is shaped away from the main body portion of the locking operation knob 2, the presence of the reinforcing rib 4D ensures that the operation surface portion 4C is moved to the vertical operation portion 4B. A pressing force can be transmitted. The up / down operation unit 4B is always urged upward by a restoring spring or the like (not shown). The reinforcing rib 4D is configured to smoothly move up and down while being guided by a slit portion 8 formed in the main body portion of the locking operation knob 2.
The push button 4 is urged in the counter-pressing direction (upward) by a restoring spring or the like (not shown), and a lower end locking projection 4E formed to project from the lower end of the vertical operation unit 4B is shown in FIG. It is comprised so that it may latch on the cancellation | release latching notch 3A of the circular arc groove 3 in FIG.

Further, as shown in FIG. 2A, the top 2A of the front wall 2B of the main body of the locking operation knob 2 is provided.
A notch 2E is formed in the vicinity immediately below, and the exposed portion 4G in which the vicinity immediately below the top 4A of the push button 4 is partially exposed is visible. By coloring the exposed portion 4G, etc. Thus, the pressing operation of the push button 4 can be easily visually confirmed. Furthermore, the main body portion of the locking operation knob 2 is a glossy processing surface, and the arrow portion of the push button pressing direction display portion 2C is a glossy processing.
Visibility can be improved by making the arrow part conspicuous. Thus, in order to improve the visibility of the push button pressing direction display portion 2C, the surface treatment of the main body portion of the locking operation knob 2 and the push button pressing direction display portion 2C may be appropriately changed. Furthermore, as shown in FIG.
The guide ribs 4F projecting in the same direction as the lower end locking projections 4E and the ribs along the shape of the main body of the locking operation knob 2 formed with the slits 8 By overlapping the upper end portion of 2D in the pressing movement direction of the up / down operation portion 4B, the operation of the up / down operation portion 4B is smoothly guided and pressed without being shaken when the push button 4 is operated. Further, the lower end portion of the edge rib 2D along the shape of the main body portion where the slit portion 8 is formed in the locking operation knob 2 and the opposite side thereof are each formed in a gentle arc shape, and the string of the passenger's bag or the like is formed. It is configured so that it can be easily detached even if it is caught. Preferably, the side on which the operation surface portion 4C of the push button 4 is disposed is formed in a gentle arc with a small curvature.

Thus, in the unlocking position of the bag shown in FIG. 1 (A), the top 4A is configured to be below the top 2A position of the locking operation knob 2. Despite being not pressed, the operation surface portion 4C having a shape away from the main body of the locking operation knob 2 can sufficiently secure a large contact area between the push button 4 and the finger, so that the push button 4 can be surely pressed. By operating, the up / down operation portion 4B is easily moved downward against the restoring force of the upward restoring spring (not shown), and the lower end locking projection 4E at the lower end thereof is disengaged in the arc groove 3. It can be released from the lock notch 3A and opened, and the ridge can be moved to the lock position. In other words, an extremely effective circle lock is proposed in which the contradictory characteristics of suppressing the numbness of the push button 4 and improving the operability are compatible with a simple structure. In addition, in the said structure, the top part 4A of the pushbutton 4 is comprised below the top part 2A position of the locking operation knob 2.
In the pressing operation direction of the push button 4 (the arrow direction of the push button pressing direction display portion 2C), the top portion 4 of the push button 4
A is configured below the top portion 2A of the locking operation knob 2, and regarding the anti-slip unevenness formed on the operation surface portion 4C of the push button 4, the above-described positional relationship includes the unevenness of the operation surface portion 4C of the push button 4. It will be understood that the non-slip unevenness may appear higher than the top 2A of the locking operation knob 2 in the drawing notation.
