FIG. 6 is a side view of the umbrella stand lock, and FIGS. 7A and 7B are cross-sectional views of FIG. 5 showing an open state and a closed state of the opening / closing cover.

The case 10 of the umbrella stand lock is composed of an upper case 11, a lower case 12 and a rear wall 13 (see FIG. 6), and a groove into which the rear wall 13 is fitted in the upper case 11 and the lower case 12. 14 (see FIG. 7 (A)), a hole 15 is provided in the joint surface of the lower case 12, and a screw hole (not shown) corresponding to the hole 15 is provided in the joint surface of the upper case 11. Then, the screw 16 inserted into the hole 15 is screwed into the screw hole, and the upper case 11 and the lower case 12 are fastened (see FIG. 6).

Four holes 17 are formed in the rear wall 13 (see FIG. 1), and a mounting bolt 18 (see FIG. 2) inserted into the hole 17 allows the umbrella stand lock to be a frame (shown in the figure) of the umbrella stand. Not). L-shaped standing walls 19 and 19 standing upright from the lower end edge of the rear wall 13 are provided. Stop rings 21 are fitted to both ends of a spindle 20 penetrating the standing walls 19 and 19, and the spindle 20 is supported. Side walls 23, 23 standing upright on both sides of the base piece 22a of the umbrella detector 22 are pivotally attached to the.

An umbrella contact portion 24 is attached to a lower end portion of the base piece 22 a, one end 25 a of a spring 25 wound around the support shaft 20 is locked to the side wall 23, and the other end 25 b is locked to the rear wall 13. (See Figure 1). Therefore, the umbrella detector 22 is biased in the direction of arrow F shown in FIG. A stopper 26 is extended on the upper end of the umbrella detection unit 22, and when the umbrella detection unit 22 tilts in the direction of arrow F, the stopper 26 is in an upright state.

A lock insertion hole 27 is provided in the upper case 11 and the lower case 12 (see FIG. 7A), and a cylinder lock 28 is inserted into the lock insertion hole 27 and is provided at an upper end surface of the cylinder lock 28. The key K is inserted into the key hole. The end of the rotor 28a of the cylinder lock 28 is formed in a quadrangular shape, and the cam lever 29 fixed to the end of the rotor 28a has a protrusion 30 extending at one end and a spring receiver 31 at the other end. A chevron-shaped cam surface 32 is formed on the portion (see FIG. 8A).

A spring 33 is inserted between the spring receiver 31 and the lower case 12, the cam lever 29 is biased in the direction of the arrow R, which is the locking direction, and the projection 30 abuts the stopper 26 in the upright state. . An umbrella housing groove 34 is provided on the front surfaces of the upper case 11 and the lower case 12 that are overlapped with each other, and a laterally long hole 35 that opens to the umbrella housing groove 34 is formed on a joint surface between the upper case 11 and the lower case 12. It

A pivot 36 is inserted into the upper wall surface and the lower wall surface of the laterally long hole 35, and one end of an opening / closing lever 37 described below is fixed to this pivot shaft 36, and one end of an umbrella receiving lever 38 is pivotally attached thereto. One end of the umbrella receiving lever 38 is formed in a bifurcated shape by a cutout portion 38a, one end of the opening / closing lever 37 is rotatably inserted into the cutout portion 38a, and a segment-like shape is formed on the outer peripheral surface of one end of the opening / closing lever 37. A gear 39 is provided.

A shaft 40 penetrating the notch 38 a is fixed to the umbrella receiving lever 38, and a pinion 41 rotatably attached to the shaft 40 meshes with a gear 39 and a segment provided in the case 10. It also meshes with the internal gear 42. A protrusion 42a is provided on the upper surface of the internal gear 42, and one end 47a of the spring 47 wound around the protrusion 42a is locked to a pin 48 provided upright on the upper surface of the umbrella receiving lever 38, and the other end of the spring 47 is 47b is locked to the internal gear 42 (see FIG. 7B).

Therefore, as shown in FIG. 7 (A), the opening / closing lever 37 projects to the front of the case 10 to open the umbrella housing groove 34, and the umbrella receiving lever 38 projects into the umbrella housing groove 34. . When the umbrella is inserted into the umbrella accommodating groove 34, the umbrella receiving lever 38 pushed by the umbrella rotates together with the pivot 36 in the clockwise direction (direction of arrow S in FIG. 7A), and the pinion 41 moves to the internal gear 42. Rotating counterclockwise while meshing, the opening / closing lever 37 rotates clockwise with a larger rotation amount than the umbrella receiving lever 38 to close the umbrella housing groove 34, and the opening / closing lever 37 and the umbrella receiving lever 38. Holds an umbrella.

As shown in FIG. 8A, inside the case 10, a roller contact surface 43 a is provided in the vicinity of the pivot shaft 36, and a roller housing with a bottom is provided between the roller contact surface 43 a and the pivot shaft 36. The recess 43 is formed, and the spring 44 and the roller 45 are inserted into the roller housing recess 43. The roller accommodating recess 43 is narrowed toward the opening at the tip, and a wedge surface is formed between the outer peripheral surface of the pivot 36 and the roller contact surface 43a to prevent the roller 45 from projecting (see FIG. 9). ). Therefore, when the roller 45 is in pressure contact with this wedge surface, the roller 45 prevents the pivot 36 from rotating counterclockwise.

As shown in FIG. 8 (A), one end 46 a of the release lever 46 pivotally attached to the case 10 at the intermediate portion is in contact with the cam surface 32, and the other end 46 b is close to the roller 45. Then, when the cam lever 29 is rotated clockwise (unlocking direction), the release lever 46 whose one end 46a is pressed by the cam surface 32 rotates counterclockwise, and the roller 45 which is pressed by the other end 46b moves. With the backward movement from the wedge surface, the pivot 36 can rotate counterclockwise, and the opening / closing lever 37 can be opened to take out the umbrella.

The operation of the umbrella stand lock configured as described above will be described in the order of non-use state, insertion of the umbrella, locking and unlocking. When the umbrella stand lock is not used, the umbrella detector 22 tilts in the direction of the arrow F and the stopper 26 stands up (see FIG. 3A), but the umbrella detector 22 is hidden under the case 10. Therefore, it is difficult for the general public to notice and it is in a position where it is difficult to operate without permission. The opening / closing lever 37 projects forward of the case 10, and the umbrella housing vertical groove 34 is opened (see FIG. 7 (A)).

Since the projection 30 of the cam lever 29 is in contact with the stopper 26, the cam lever 29 is prevented from rotating counterclockwise. Since the rotor 28a of the cylinder lock 28 cannot rotate counterclockwise together with the cam lever 29, it cannot be locked and the key K cannot be removed.

When the 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), and the stopper 26 tilts to the left and separates from the protrusion 30. Therefore, the cam lever 29 becomes rotatable and is moved 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. The umbrella receiving groove 34 is moved to close and the opening / closing lever 37 and the umbrella receiving lever 38 clamp the umbrella (see FIG. 7B).

When the pivot shaft 36, which is integrated with the umbrella receiving lever 38, rotates in the clockwise direction, it pushes the roller 45 contacting the pivot shaft 36 in the direction away from the wedge surface. However, since the roller 45 contacting the pivot 36 engages with the wedge surface when the pivot 36 rotates counterclockwise, when the umbrella receiving lever 38 is completely pushed by the umbrella, Will be locked.

Therefore, the umbrella can be stored in the locked state 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 opening / closing lever 37 and the umbrella receiving lever 38 can uniformly hold and store the umbrella. If the umbrella is not inserted into the umbrella accommodating groove 34, the key K cannot be removed, so that mischief to extract only the key K is prevented.

When the key K inserted in the key hole is rotated clockwise in FIG. 8B after the storage of the umbrella is finished, the cam surface 32 pushes the one end 46a of the unlocking lever 46 to move it counterclockwise. The other end 46b of the rotated unlocking lever 46 pushes the roller 45 into the roller accommodating recess 43, and the pivot 36 becomes rotatable in the counterclockwise direction, and the umbrella receiving lever 38 integral with the pivot 36 and the opening / closing lever 37. Also becomes rotatable. Therefore, it is possible to take out the umbrella with a simple operation of pulling out the umbrella as it is.

In the above-described embodiment, the roller 45 is engaged with the pivot shaft 36 to lock it, and the unlocking lever 46 rotated by the cylinder lock 28 releases the engagement of the roller 45 to unlock the structure. As a matter of fact, the umbrella can be stored uniformly regardless of the thickness of the umbrella, but the opening / closing lever 37 may be directly locked / unlocked by the cylinder lock 28. Further, although the umbrella receiving lever 38 is provided and the opening / closing lever 37 is automatically closed when the umbrella receiving lever 38 is pushed, the umbrella detecting unit is provided in the conventional umbrella stand lock that closes the opening / closing lever by hand. It is also possible.
