However, since the protrusion is simply hooked on the groove, there is a possibility that the protrusion can be easily detached from the groove due to strong wind and rain when the handle is attached. There are problems such as flying umbrellas. In addition, when the handle main body is removed, other parts such as a coil spring are also removed together, and there is a problem that these parts must be held together with the handle main body without being lost.

  Therefore, the present invention solves the above-described problems of the prior art, and the handle can be removed from the umbrella body by simply performing an operation, and the handle does not easily fall off when the handle is attached to the umbrella body. An object of the present invention is to provide an umbrella handle attaching / detaching device that can prevent theft of the umbrella and the like by removing the handle.

The umbrella handle attaching / detaching device of the invention for achieving the above-mentioned object is an umbrella handle attaching / detaching device adapted to detachably attach a handle to an umbrella main body, and is provided with a locking pin on a middle rod of the umbrella main body, The handle is formed with a receiving hole for receiving the center rod, and the receiving hole rotatably holds an auxiliary cylinder in the hole and has a guide groove for guiding the locking pin on the inner wall of the receiving hole. And a first urging means for urging the intermediate rod in the axial direction and a second urging means for urging the auxiliary cylinder in the circumferential direction at the bottom of the receiving hole. A cam groove that fits the locking pin is formed in the auxiliary cylinder, and when the handle is attached to the umbrella body, the guide groove is inserted into the middle rod of the umbrella body through the receiving hole. The locking pin of the center rod that has entered inside is advanced to the locking pocket portion of the cam groove against the first and second urging means. When the handle is removed from the umbrella body, the auxiliary cylinder is rotated by hand against the second urging means so that the locking pin is removed from the locking pocket portion.

The locking pin 111 of the middle rod 110 is guided through the cam groove 230 from the opening end to the locking pocket portion 232 through the inclined portion 231 on the way while being guided in the guide groove 211.

An engaging recess 212 is formed on the periphery of the bottom of the receiving hole 210. On the other hand, an engagement piece 221 is formed on the periphery of the bottom of the auxiliary cylinder 220. The auxiliary cylinder 220 is held in the receiving hole 210 and is rotatable by being engaged with the engaging recess 212 of the receiving hole 210 by the engaging piece 221.
However, the rotatable range of the auxiliary cylinder 220 is restricted to a certain range by the recess width of the engagement recess 212.
The size of the recess width of the engagement recess 212 is set to be slightly larger than the displacement width in the circumferential direction of the cam groove 230 of the auxiliary cylinder 220. This restricts the auxiliary cylinder 220 from rotating more than necessary.
More specifically, in a state where the engagement piece portion 221 is in contact with one end of the engagement recess 212, the circumferential position of the opening end of the cam groove 230 coincides with the position of the guide groove 211, Further, the locking pocket portion 232 is configured to coincide with the position of the extended end. Further, when the locking pin 111 passes through the inclined portion 231 of the cam groove 230, the engagement piece portion 221 is moved to the vicinity of the other end of the engagement recess 212.

4 to 6, the position where the guide groove 211 coincides with the opening end of the cam groove 230 and the position where the guide groove 211 coincides with the extended end of the locking pocket portion 232 of the cam groove 230 are the normal positions.

  The auxiliary cylinder 220 is formed with a retaining groove 222 at the bottom periphery thereof. The second urging means 400 fixed to the bottom of the receiving hole 210 is hooked on the hooking groove 222. As a result, the auxiliary cylinder 220 is held in the biased state in the circumferential direction by the second biasing means 400.

Referring to FIG. 3, the first urging means 300 and the second urging means 400 are configured to be attached to a spring seat portion 500. The spring seat 500 is integrally attached to the bottom of the receiving hole 210, that is, the bottom of the hole-forming cylinder 201.
The first urging means 300 is specifically composed of a pushing urging spring 310, and the second urging means 400 is specifically composed of a circumferential urging spring 410.
The pushing biasing spring 310 that is the first biasing means 300 pushes and biases the middle rod 110 of the umbrella body 100 in the receiving hole 210 in the axial direction.
Further, a circumferential urging spring 410 as the second urging means 400 is hooked on the retaining groove 222 of the auxiliary cylinder 220 and urges the auxiliary cylinder 220 to rotate in the circumferential direction.

The auxiliary cylinder 220 has a collar 223 formed at the end on one end side. The collar portion 223 is in a state of projecting from one end of the hole constituting cylinder 201 constituting the receiving hole 210.
An example of assembling the apparatus will be described. The spring seating portion 500 to which the pushing biasing spring 310 and the circumferential biasing spring 410 are attached is fixed to the bottom of the hole-forming cylinder 201. Then, by engaging the auxiliary cylinder 220 with the engagement concave portion 212 of the hole constituting body 201 by the engagement piece 221, the auxiliary cylinder 220 can freely rotate within the inner hole of the hole constituting body 201, that is, the receiving hole 210. Hold on. Then, the circumferential biasing spring 410 fixed to the hole structure 201 is latched in the latching groove 222 of the auxiliary cylinder 220.

The operation of the pattern attaching / detaching apparatus 1 for the umbrella with the above configuration will be described.
Now, in a state where the handle 200 is removed from the umbrella body 100, the guide groove 211 of the receiving hole 210 of the handle 200 and the open end of the cam groove 230 of the auxiliary cylinder 220 are in a state of being in a steady state U. In this state, the handle 200 is inserted into the umbrella body 100 through the receiving hole 210. When inserting, the locking pin 111 of the middle rod 110 of the umbrella body 100 is engaged with the guide groove 211 of the receiving hole 210 of the handle 200 and the opening end of the cam groove 230 of the auxiliary cylinder 220 overlapping therewith. That is, the locking pin 111 is positioned at the position shown in FIG.
As the handle 200 is inserted, the middle rod 110 enters the axial direction against the first urging means 300, and accordingly, the locking pin 111 enters along the guide groove 211. . When the position of the locking pin 111 enters the position of the cam groove 230 of the auxiliary cylinder 220 (the biasing position I shown in FIG. 5), the circumferential biasing that is the second biasing means 400 is performed. The auxiliary cylinder 220 is rotated in the circumferential direction by an amount corresponding to the bias by the spring 410. At this time, the engagement piece 221 of the auxiliary cylinder 220 is separated from the one end of the engagement recess 212 of the receiving hole 210. When the locking pin 111 reaches the lower end of the inclined portion 231 and is detached from the inclined portion 231, the engaging pin 111 is released from the inclined portion 231, thereby biasing the circumferential biasing spring 410. As a result, the auxiliary cylinder 220 is rotated, and as a result, the locking pin 111 enters the locking pocket portion 232 to the extended end position, that is, the steady position U (position shown in FIG. 6) and is positioned. In this position, the locking pin 111 cannot move in any of the vertical, horizontal, and horizontal directions due to the restriction of the guide groove 211 and the cam groove 230. That is, the handle 200 is coupled to the umbrella body 100 and the attachment of the handle is completed.

  On the other hand, when removing the handle 200 from the umbrella body 100, the collar 223 of the auxiliary cylinder 220 is turned by hand against the circumferential urging force, thereby the locking pin 111. Can be detached from the locking pocket portion 232 of the auxiliary cylinder 220. In this state, the pushing biasing spring 310 that is the first biasing means 300 operates in the state of being detached, and the middle rod 110 is pushed up in the axial direction, so that the handle 200 can be easily pulled out upward. Thereby, the handle 200 can be removed from the umbrella body 100. In this removal, only the handle 200 can be removed, and other parts will not come off together. Therefore, since the user can easily remove the handle 200 and leave only the umbrella body 100 when the user is outside, the handle 200 can be prevented from being taken away or stolen. Since the handle 200 can be stored by itself, for example, a favorite expensive handle can be attached.
