Description

[Detailed Description of the Invention] Industrial Field of Use This invention relates to an open umbrella state maintaining device for a folding western umbrella, which locks the lower potter's wheel against the umbrella handle in an open state so as not to be able to move downward.

Conventional technology Folding Western umbrellas use a four-stage telescopic umbrella handle as disclosed in Publication of Utility Model Publication No. 57-46816, for example, to ensure a compact size that can be easily placed in a woman's handbag when the umbrella is folded. Efforts are being made to do so.

As disclosed in the above-mentioned publication, maintaining the open state in such a folding western umbrella is generally done by attaching a plurality of umbrella stem tubes to the topmost umbrella stem tube, which is made up of a plurality of umbrella stem tubes that are fitted together in an expandable manner. A locking piece made of a plate spring is fixedly attached to the umbrella handle tube, and the locking part at the upper end of this locking piece projects outward from the window hole of the umbrella handle, and the lower edge of the lower potter's wheel in the umbrella opening position. This has been done by engaging the

Problems to be Solved by the Invention Conventional umbrella opening state maintaining devices like this do not work at a certain level when trying to increase the number of umbrella handle tubes and make the umbrella handle multi-stage to make the umbrella more compact when the umbrella is closed and folded. give the constraints.

In other words, in order to shorten the shortened length of the umbrella handle, each umbrella handle tube is shortened and the number of expansion and contraction stages is increased, but the length of the locking piece for maintaining the umbrella in the open state must not exceed a certain level. Then, it no longer has the elasticity to support the lower potter's wheel, which is subject to a fairly large downward pressing force in the open state. In this way, since the locking piece, which occupies a considerable length, is provided in the uppermost umbrella handle tube below the lower edge position of the lower potter's wheel in the umbrella opening position, it is possible to Therefore, other umbrella stem tubes are also prevented from shortening accordingly.

Therefore, this invention provides an open state maintaining device that allows the length of the topmost umbrella stem tube to be made shorter than in the conventional case, thereby contributing to the compactness of the closed and folded state of folding western umbrellas. That is the issue.

Means for Solving the Problems To this end, this invention, as illustrated in the attached drawing, locks the upper end of a locking piece 14 that is fixed to the uppermost umbrella handle tube 1 and provided within the umbrella handle tube 1. In a folding western umbrella in which the lower potter's wheel 7 is retained at the portion 14a to maintain the open state, a cylindrical portion 7b that is integrally formed with the lower potter's wheel 7 above the pivot portion of the strut 9,
A window hole 15 is provided into which the locking part 14a of the locking piece 14 can enter when the umbrella is in the open state, and the locking part 14a is engaged with the upper edge of the window hole 15 to maintain the umbrella in the open state. . A push button 1 whose leg is supported by a vertical slit formed in the pivot part 7a and rotatably supported by the pivot part 7a by a wire 17 for supporting the bone.
6 is provided to engage with the outer edge of the locking portion 14a, and the locking of the lower potter's wheel 7 is released by pushing the push button 16.

Function The locking piece 14, which pushes the upper end locking part 14a into the window hole 15 of the upper side cylinder part 7b of the lower potter's wheel 14 and engages with the upper edge of the window hole 15, rotates the lower potter's wheel 7 on the umbrella handle. The umbrella is locked so as not to be able to move downward to maintain the open state as required.

Effects of the invention This invention allows the lower potter's wheel to lock at the lower potter's wheel locking position by the upper end locking part 14a of the locking piece 14 which is fixed to the umbrella handle tube 1 at the top stage and provided inside the umbrella handle tube 1.
The cylindrical portion 7b is located above the bone support portion 7a.
As the upper end position of the window hole 15 provided in the umbrella is required to have elasticity to receive and support the lower potter's wheel 7, which is subjected to a considerable pressing force in the open position, and to lock onto the umbrella handle, a length of more than a certain degree is required. Since the locking piece 14 is provided in the uppermost umbrella stem tube 1 at a position that is considerably raised by the height H illustrated in FIG. 1 than in the conventional case, the uppermost umbrella stem tube 1 1 can be made shorter than in the conventional case.

Therefore, according to this invention, the uppermost umbrella handle tube 1
At the same time, the other umbrella handle tubes constituting the extendable umbrella handle are also shortened to increase the number of extension stages of the umbrella handle, thereby increasing the compactness of the folding western umbrella in the closed and folded state.

When closing the umbrella, the locking piece 14 provided as described above is unlocked by extending a finger upward from between the struts 9 and pushing in the locking part 14a, as shown in FIG. On the other hand, in this invention, a push button 16 supported on the support bone pivot 7a of the lower potter's wheel is provided, and the locking part 14a is pushed in through this push button 16, so that when viewed in the radial direction of the lower potter's wheel 7. The push button 16, which is located outside the locking part 14a and is easy to touch with the finger, and which allows operation at an outer position as far away from the lower wheel 7 as possible, makes it possible to release the lock of the lower wheel 7 as much as possible. This effect can be achieved by pressing button 16 as shown in the embodiment.
This can be further enhanced by simple measures such as making the width relatively large.
In addition, this push button 16 has a leg supported by a vertical slit formed in the support part 7a of the lower potter's wheel 7, and is supported by the support part 7a using a wire 17 for the support part. The above-mentioned vertical slits can be formed at the same time as the plurality of vertical slits formed in the pivot portion 7a for supporting the plurality of struts 9 by adding one. The manufacturing of the lower wheel 7 is not made difficult at all, and the wire 17 is originally used for supporting the lower wheel, so it can be provided at low cost.

Therefore, in this invention, in order to increase the compactness of the folding umbrella in the closed state, the locking piece locking portion 14a, which is positioned above the strut 9 in the open state, is replaced by a simple structure. The support structure also provides the advantage of being able to perform the unlocking operation very easily using the push button 16, which can be done at low cost.
