The end of the rotor 28a of the cylinder lock 28 is formed in a quadrangular shape. The cam lever 29 fixed to the end of the rotor 28a has a protrusion 30 at one end, a spring receiver 31 at the other end, and a central portion. The cam surface 32 having a chevron shape is formed in FIG.
(A)).

A spring 33 is inserted between the spring receiver 31 and the lower case 12, the cam lever 29 is urged in the direction of the arrow R which is the locking direction, and the projection 30 comes into contact with the stopper 26 in the upright state. An umbrella accommodating groove 34 is provided on the front surface of the superposed upper case 11 and lower case 12, and a horizontally long hole 35 opening in the umbrella accommodating groove 34 is formed on a joint surface between the upper case 11 and the lower case 12. You.

A pivot 36 is provided on the upper wall and the lower wall of the horizontally long hole 35.
One end of an opening / closing lever 37 described below is fixed to the pivot 36, and one end of an umbrella receiving lever 38 is pivotally attached. One end of the umbrella receiving lever 38 is bifurcated by a notch 38a, and one end of the opening / closing lever 37 is rotatably inserted into the notch 38a. A gear 39 is provided.

A shaft 40 penetrating the notch 38a is fixed to the umbrella receiving lever 38. A pinion 41 rotatably mounted on the shaft 40 meshes with a gear 39, and the case 1
It also meshes with the segment-shaped internal gear 42 provided in the inside. A projection 42 a is provided on the upper surface of the internal gear 42, and one end 47 a of a spring 47 wound around the projection 42 a is locked by a pin 48 erected on the upper surface of the umbrella receiving lever 38, and the other end 47 b of the spring 47 Are locked to the internal gear 42 (FIG. 7).
(B)).

Accordingly, as shown in FIG. 7A, the opening / closing lever 37 projects to the front of the case 10 to open the umbrella receiving groove 34, and the umbrella receiving lever 38 projects into the umbrella receiving groove 34. When the umbrella is inserted into the umbrella accommodating groove 34, the umbrella receiving lever 38 pressed by the umbrella and the pivot 36 rotate clockwise (FIG. 7).
(A), the pinion 41 rotates counterclockwise while the pinion 41 is engaged with the internal gear 42, and the opening / closing lever 37 rotates clockwise with a larger rotation amount than the umbrella receiving lever 38. The opening and closing lever 37 and the umbrella receiving lever 38 pinch the umbrella.

As shown in FIG. 8A, a roller contact surface 43a is provided near the pivot 36 inside the case 10, and a roller housing recess with a bottom is provided between the roller contact surface 43a and the pivot 36. A spring 43 and a roller 45 are inserted into the roller accommodating recess 43. The roller accommodating recess 43 narrows toward the opening at the tip, and the roller 4 is located between the outer peripheral surface of the pivot 36 and the roller contact surface 43a.
A wedge surface is formed to prevent the projection 5 from projecting (see FIG. 9). Therefore, when the roller 45 is in pressure contact with the wedge surface, the roller 45 prevents the pivot 36 from rotating counterclockwise.

As shown in FIG. 8A, one end 46a of a release lever 46 pivotally connected to the intermediate portion of the case 10 contacts the cam surface 32, and the other end 46b is close to the roller 45. Then, when the cam lever 29 is rotated clockwise (unlocked direction), the release lever 46 whose one end 46a is pressed by the cam surface 32 rotates counterclockwise, and the roller 45 that is pressed by the other end 46b is rotated. Retreating from the wedge surface, the pivot 36 becomes rotatable in the counterclockwise direction, and the umbrella can be taken out by opening the opening / closing lever 37.

The operation of the umbrella stand lock constructed as described above will be described in the order of non-use, insertion of the umbrella, locking and unlocking. When the umbrella stand lock is not used, the umbrella detector 22 tilts in the direction of arrow F, and the stopper 26 stands up (see FIG. 3A), but the umbrella detector 22 is hidden below the case 10. Because it is, it is hard to be noticed by ordinary people, and it is in a position where it is difficult to operate without permission. Open / close lever 37 is case 1
0, and the umbrella-housing groove 34 is open (see FIG. 7A).

The protrusion 30 of the cam lever 29 is
, The cam lever 29 is prevented from rotating counterclockwise. Rotor 28a of cylinder lock 28
Cannot be rotated counterclockwise together with the cam lever 29, and therefore cannot be locked, and the key K cannot be removed.

When an umbrella is inserted into the umbrella accommodating groove 34, the umbrella detector 22 rotates in the direction opposite to the arrow F (see FIG. 3A).
The stopper 26 tilts to the left and separates from the projection 30. Therefore, the cam lever 29 becomes rotatable and moves to the position 30 'by the pressing force of the spring 33, so that the key K can be removed.

On the other hand, when the umbrella is inserted into the umbrella accommodating groove 34, the umbrella receiving lever 38 pushed by the umbrella rotates clockwise in FIG. 7A, so that the opening / closing lever 37 rotates in the same direction. Then, the umbrella accommodating groove 34 is closed, and the opening / closing lever 37 and the umbrella receiving lever 38 clamp the umbrella (see FIG. 7B).

When the pivot 36 integrated with the umbrella receiving lever 38 rotates clockwise, the roller 45 contacting the pivot 36 is pushed in a direction away from the wedge surface, so that the pivot 36 is free to rotate clockwise. Although the roller can rotate, the roller 45 in contact with the pivot 36 engages with the wedge surface when the pivot 36 rotates counterclockwise, so that the locked state is reached when the umbrella receiving lever 38 is completely pushed by the umbrella. Becomes

Therefore, the umbrella can be kept locked by a simple operation of inserting the umbrella into the umbrella accommodating groove 34, and the key K can be pulled out and carried. In addition, regardless of the thickness of the umbrella, the umbrella can be uniformly held between the opening / closing lever 37 and the umbrella receiving lever 38 for storage. When the umbrella is not inserted into the umbrella accommodating groove 34, the key K cannot be extracted, so that mischievous removal of the key K alone is prevented.

After storing the umbrella, the key K inserted into the keyhole
Is rotated clockwise in FIG. 8B, the cam surface 3
2 pushes one end 46a of the unlocking lever 46, and the other end 46b of the unlocking lever 46 that has turned counterclockwise pushes the roller 45 into the roller receiving recess 43, and the pivot 36 turns counterclockwise. Umbrella receiving lever 3 integrated with the pivot 36
8, the opening / closing lever 37 can also be turned. Therefore, the umbrella can be taken out by a simple operation of pulling out the umbrella as it is.

In the above embodiment, the roller 45 is
And unlocked by releasing the engagement of the roller 45 with the unlocking lever 46 which is rotated by the cylinder lock 28, and can be uniformly stored regardless of the thickness of the umbrella. However, the structure may be such that the opening / closing lever 37 can be locked and unlocked directly by the cylinder lock 28. Further, the umbrella receiving lever 38 is provided, and the opening / closing lever 37 is automatically closed when the umbrella receiving lever 38 is pressed, but the umbrella detecting unit is provided in the conventional umbrella stand which manually closes the opening / closing lever. It is also possible.
