When the bottom wheel 8 moves to a position where it is locked by a stopper 15 (see FIG. 2) provided on the shaft portion 2, the bottom wheel 8 is positioned below the connecting portion 16 and is formed on the bottom wheel 8. The surface 8 a is configured to be releasably locked by the upper repellent 14.

  1 to 3 show the structure of the scissors 8 according to the first embodiment of the present invention. The main body 18 of the lower wheel 8 is formed of a synthetic resin cylinder, and the hollow portion 20 is slidably fitted to the shaft portion 2. A connecting portion 16 is formed in a flange shape at an intermediate portion of the main body 18, and each end of the receiving bone 12 a of the bone portion 12 is pivotally supported by the recessed groove portion 22 formed on the outer peripheral surface of the connecting portion 16. The movement of the lower wheel 8 with respect to the shaft portion 2 is restricted by the coupling with the receiving bone 12a.

At the end of the connecting portion 16 on the umbrella handle side, a locking surface 8a perpendicular to the axial direction of the bottom pole 8 is formed. At the end of the main body 18 on the umbrella handle side, there is an interval of approximately the same length as the entire length of the outer protruding portion 14a of the upper repellant 14 between the connecting portion 16 and the flange portion 24. Are integrally formed, and an operation piece 26 having elasticity and flexibility, which extends toward the connecting portion 16 side, is integrally formed along the axial direction of the main body 18 on the outer diameter portion of the flange portion 24. Is formed.

The upper open end side of the operation piece 26 is opposed to and parallel to a thin plate-like cover piece 27 formed integrally with the connecting portion 16. The cover piece 27 prevents the operation piece 26 from jumping outward. A slit 30 having a predetermined width that opens the outer protruding portion 14a of the upper repellency 14 from the tube wall 28 is formed in the tube wall 28 of the cylindrical portion between the connecting portion 16 and the flange portion 24 of the main body 18. Has been.

In this embodiment, the lateral width of the slit 30 is set to a range in which the tube wall 28 is cut out by approximately 90 degrees in the circumferential direction. The upper end surface of the slit 30 is formed on the same surface as the lower surface of the connecting portion 16, and constitutes a locking surface 8a together with the lower surface. The distal end of the operation piece 26 is opposed to the lower end surface having the locking surface 8a of the connecting portion 16 with a predetermined interval, and the operation piece 26 is directed from the flange portion 24 to the slit 30. It extends in parallel at a predetermined interval.

The lateral width of the operation piece 26 is set wider than the thickness of the outer protrusion 14 a of the upper repellent 14, and is narrower than the lateral width of the slit 30. As shown in FIG. 2, the operation piece 26 faces the outer protruding portion 14 a of the upper flip 14 in a state in which the downward movement is locked by the upper flip 14 as shown in FIG. 2. ing.

  In the above-described configuration, when the umbrella is closed, the bottom pole 8 is positioned below the top flip 14. When the umbrella is opened, the shaft portion 2 is extended, and the bottom wheel 8 is moved along the shaft portion 2 in the direction of the tip of the tip against the elastic force from the bone portion 12 by manual operation. During the movement, when the lower wheel 8 passes through the upper repellent 14, the upper repellent 14 is pressed toward the inside of the shaft portion 2 by the inner peripheral surface of the hollow portion 20 of the lower crossing 8, and the outer protruding portion 14a is Then, the shaft portion 2 is retracted against the spring force.

When the bottom wheel 8 further moves to a position where it collides with the stopper 15, the slit 30 of the bottom wheel 8 moves directly above the outer protrusion 14 a of the top repellent 14. When the slit 30 moves to the outer protruding portion 14a of the upper repellent 14, as shown in FIG. 2, the upper repelling 14 is released from the pressing force from the lower wheel 8, and the outer protruding portion 14a is released from the inside of the shaft portion 2. The stopper portion 14b of the outer protruding portion 14a faces the locking surface 8a of the bottom rail 8 due to the spring force.

As a result, the lower wheel 8 is prevented from moving downward along the shaft portion 2 by the upper repelling 14, and the lower wheel 8 is locked at a predetermined position on the tip side of the upper slide shaft 6. In the state where the lower wheel 8 is locked to the upper flip 14, the umbrella is opened as shown in FIG. When it is desired to close the umbrella, the operation piece 26 is pushed by the belly of the finger, bent, and the upper repelling 14 is pushed inwardly of the shaft portion 2 as shown in FIG.

As a result, the upper peg 14 is unlocked from the lower peg 8, and the lower peg 8 can freely slide along the shaft portion 2 in the direction of the umbrella pattern. In this state, the bottom wheel 8 is slid along the shaft portion 2 toward the umbrella handle, the umbrella is closed, and the shaft portion 2 is shortened.

  In the present embodiment, the telescopic shaft portion 2 is not provided with a lower repellency, but the lower repellency may be provided by being shifted in the circumferential direction with respect to the upper repellency 14. In this case, the lower repelling slit is provided in the tube wall 28 of the main body 18 adjacent to the slit 30 shown in FIG. In this case, the pipe wall 28 is formed with a locking surface (not shown) that engages with the lower end of the lower repellant by the lower repellant slit. The structure of the slit for repelling under this is a general structure, and its illustration and description are omitted.

Since the operation of releasing the repelling with the belly of the finger and releasing the locking of the bottom plow 8 by the bottom repelling can be performed with a relatively weak pressing force, there is no need to provide an operation piece for the bottom repelling on the bottom crossing 8 in particular. Also good. Needless to say, an operating piece for lower repelling may be provided on the bottom pole 8, and an embodiment in that case will be described later. When the shaft portion 2 is provided with a lower repellent and the lower cross 8 is provided with a lower repelling slit, when the umbrella is closed, the locking surface (not shown) of the lower repelling slit (not shown) on the side of the lower cross 8 ), The upper protrusion of the lower repel is engaged, and the bottom rail 8 is locked to the lower repel. This locking can be released by lightly pushing the lower repel with the belly of the finger.

Next, with reference to FIG. 5 thru | or FIG. 8, embodiment of the ironing board used for a normal long umbrella is demonstrated. The armor of this embodiment can be applied not only to a normal long umbrella but also to a foldable western umbrella having a lower repellency in which a shaft portion expands and contracts.
In FIG. 7, reference numeral 32 denotes a shaft portion of a long umbrella, which is provided with an upper repelling (not shown) and a lower repelling 34.

The shaft 8 is slidably fitted into the shaft portion 32. The upper and lower folds 34 are arranged on the movement line along the shaft portion 32 of the slit 30 of the bottom wheel 8. The lower repelling operation piece 26 has a U-shaped cut line 36 formed on the lower repelling operation piece 26, and the upper repelling operation piece 26 is provided with a U-shape having elasticity and flexibility by the cut line 36. A lower flipping operation piece 38 is formed. The other structure of the bottom wheel 8 is the same as the structure of the bottom wheel 8 of the first embodiment shown in FIGS. 1 to 3, and the same reference numerals are given to the same parts and the correspondence is clarified. I have to.

In the above-described configuration, the action of locking the bottom wheel 8 to the shaft portion 32 by upper repelling is the same as that of the first embodiment, and therefore the description thereof is omitted.
When closing the long umbrella, slide the lower skull 8 toward the umbrella handle along the shaft portion 32 until the inner peripheral surface of the collar portion 24 exceeds the lower repelling 34. When the lower repelling 34 is positioned in the slit 30 of the lower crossing 8 by this slide of the lower crossing wheel 8, the outer protruding portion 34a of the lower repelling 34 protrudes from the shaft portion 32 by the spring force and contacts the lower repelling operating piece 38. Touch it and push it slightly outward.

At this time, the locking surface 40 of the collar portion 24 of the bottom wheel 8 is perpendicular to the axial direction of the bottom wheel 8 and the stopper portion of the lower repelling 34 faces each other. The movement of the potter's wheel 8 along the shaft portion 32 is stopped. In a state in which the lower skull 8 is locked by the lower flip 34, the umbrella is closed.

When it is desired to release this locked state, as shown in FIG. 8, the lower repelling operation piece 38 is pushed with a finger, the operation piece 38 is bent toward the inside of the main body 18, and the lower repelling 34 is moved to the shaft portion 32. Retract inward. As a result, the lower repelling 34 is disengaged from the lower runner 8, and the lower runner 8 is freely slidable along the shaft portion 32 in the stone bump direction.
