Description

[Detailed description of the invention] This invention is a hand-operated locking piece operating device for a retractable umbrella. More specifically, this invention is a hand-operated locking piece operating device for a retractable umbrella. More specifically, the lower potter's wheel is applied to the umbrella handle when the umbrella handle is in an extended state. A locking piece operation for unlocking the locking piece by operating an operation piece that is rotatable around the lower end of the fulcrum hardware fixed to the inner surface of the umbrella handle near the hand. The device is configured such that an interlocking tool provided in the umbrella handle is extendable and retractable together with the umbrella handle so as to be pulled down by the operation of the operating piece to release the locking piece. The present invention relates to a certain locking piece operating device.

A locking piece operating device for a retractable umbrella configured as described above is already known from, for example, Japanese Patent Publication No. 48-42585. The locking piece operation device disclosed in the same publication is a locking piece operating device that is used in an automatic closing type three-stage telescopic umbrella, and the lower wheel is placed in the open position on the extended umbrella handle, and the locking piece is locked to the umbrella handle so that the lower wheel cannot move downward. The locking piece is configured to be unlocked by manual operation to automatically close the umbrella. The above-mentioned locking piece is for locking the lower potter's wheel at the position of the uppermost part (upper handle) of the three-stage umbrella handle, which is telescope-like and expandable and retractable. On the other hand, the operating piece near the hand is arranged on the lowermost umbrella handle (lower handle), and the locking piece at the upper position and the lower position are the same. The interlocking tool provided in the umbrella handle for interlocking connection with the operating piece of the umbrella handle is extended when the umbrella handle is extended to connect the locking piece and the operating part as required, and When the umbrella is shortened, it is said to be shortened to allow the same umbrella handle to be shortened.

The above-described locking piece operation device is for an automatic closing type telescopic umbrella, but if the automatic opening type telescopic umbrella is a three-stage or four-stage telescopic type, such automatic opening type telescopic umbrella can be used. When a retractable umbrella is of the type that can be opened automatically by manual operation, a locking piece operating device such as the one mentioned above, that is, a locking piece operating device in which the interlocking device provided in the umbrella handle is configured to be extendable and retractable, is used. , it is necessary to provide In other words, even if it is an automatic opening telescopic umbrella, if it is a two-stage telescopic umbrella, the lower potter's wheel position when closing the umbrella is on the extended umbrella handle and on the lower umbrella handle (lower handle). For example, in the 1970s
As disclosed in Publication No. 18688, a hand-operated type in which the operation piece is placed near the hand on the lower umbrella handle (lower handle) is also available, but there is also a lock for locking the lower potter's wheel in the closed position. The interlocking device that interlocks and connects the stop piece and the operating piece must be located exclusively within the lower umbrella handle portion (lower handle), and such interlocking device must be able to be shortened to allow shortening of the umbrella handle. However, when a self-opening telescopic umbrella is used, for example, as a three-stage telescopic umbrella, the lower potter's wheel position when closing the umbrella is on the extended umbrella handle and on the middle part of the umbrella handle (middle handle). A locking piece and a lowermost umbrella handle part (lower handle) to lock the lower potter's wheel in such a position so that it cannot move upward and maintain the umbrella closed state.
The interlocking device provided in the umbrella handle for interlocking connection with the operating piece disposed in the umbrella handle must have a length spanning the above-mentioned middle handle and lower handle when the umbrella handle is extended. If such a linking device is not shortened when the umbrella handle is shortened, it will be impossible to shorten the umbrella handle.In the end, the linking tool should be configured to be able to expand and contract together with the umbrella handle. There is a need to.

It is already known that the extensible part, which constitutes the main part of the above-mentioned interlocking tool, is composed of a sliding rod and a sliding plate that have engaging parts that engage with each other to regulate the amount of extension of the interlocking tool. It is. The interlocking tool disclosed in Japanese Patent Publication No. 48-42585 mentioned above is constructed in such a way that the sliding plate body is positioned on the upper side and the sliding rod body is positioned on the lower side, and the umbrella handle is shortened. In this state, the operating piece is housed in the umbrella handle, while the interlocking member is shortened with its sliding plate lowered to a position above the operating piece.

By the way, when such an interlocking device is shortened together with the umbrella handle, it is ideal that the lower end of the upper sliding member in the telescoping section is located below the operating piece. . One reason is that with the above, the length of the upper sliding member can be increased, and for this reason, the length of the umbrella handle is set to a large length so that when the umbrella handle is extended, the length of the upper sliding member can be increased. There is no problem even if the vertical distance between the lower potter's wheel and the operation piece to be unlocked is increased, and even if the umbrella handle length is set to a large value, the upper sliding member will be pulled down significantly when the umbrella handle is shortened. This is because the amount of shortening of the umbrella handle can be set to a large value, resulting in an umbrella handle that has a large extended length compared to the shortened length. In addition, the fact that the lower end of the upper sliding member of the interlocking tool in the shortened state is located below the operating piece means that there is no problem in placing the operating piece at a position that much higher. The piece can also be brought to an upper position where it can be easily manipulated. In other words, if the control piece is located very close to the hand, the user will have to use the palm of the hand rather than the fingers of the hand holding the hand, making it difficult to operate, whereas if the control piece is moved upward,
The operating piece can be operated reliably and easily by extending the index finger of the hand holding the handle upward.

However, in reality, an interlocking tool configured such that the lower end of the upper sliding member of the interlocking tool is shortened so as to be positioned below the operation piece has not been put to practical use. In other words, when the telescopic part of the interlocking tool is composed of a sliding rod and a sliding plate as described above, it is preferable to bring the sliding plate upward as in the above-mentioned Japanese Patent Publication No. 48-42585. In this case, since the sliding plate interferes with the operating piece, it is impossible to shorten the interlocking tool so that the lower end of the sliding plate is positioned below the operating piece.

What if a small-diameter sliding rod is placed on the upper side?It is also possible to shorten the interlocking tool with the lower end of such a sliding rod located below the operating piece. Have difficulty. That is, at the lower end of such a sliding rod, a large engaging part is formed that engages from the lower side with an engaging part formed at the upper end of the sliding plate to restrict the amount of extension of the interlocking tool. has been done. Generally, the interlocking tool and the operating piece are connected via a link piece, and the interlocking tool is pushed up on such a link piece so that when the umbrella handle is extended, a part of the operating piece is outside the umbrella handle. A spring is provided to ensure protrusion. Based on this configuration, even if the sliding rod is brought downward, the engaging portion at the lower end of the rod interferes with the pivot pins and springs at both ends of the link piece,
It is difficult to move the lower end of the sliding rod below the operating piece.

The purpose of this invention is to provide a locking piece operating device as mentioned at the beginning, which is a well-known technique in which the extending and retracting parts of the interlocking tool are engaged with each other to extend the interlocking tool. It is composed of a sliding rod body and a sliding plate body, each of which has an engaging part that regulates the amount, and is also provided with a spring that reliably projects a part of the operating piece out of the umbrella handle when the umbrella handle is extended. The interlocking tool is configured so that it can be shortened with the lower end of the upper sliding member positioned below the operation piece, and the length of the umbrella handle can be set large, and the operation piece is placed at an upper position for easy operation. An object of the present invention is to provide a novel locking piece operating device for a retractable umbrella.

The end of the support bone 8 is pivoted halfway, and the other end of the support bone 8, whose one end is pivoted to the upper lower potter's wheel 5, is pivoted midway through the main rib 9, and one end of the main bone 9 is connected to the base. The structure is such that a support bone 10 whose both ends are pivotally supported is provided in the middle of the bone 7. A tip bone 11 is pivotally supported at the tip of the main rib 9, and a well-known advancement and retraction rod 12 connects its proximal end to the support bone 8 for automatically deploying and rotating the tip bone 11 when the umbrella is opened. It is provided. Further, a spring 13 is stretched between the lower potter's wheel 6 and the support bone 8 at a proper location. And on the umbrella handle, both lower potter's wheel 5,
A coil spring 14 for automatic opening is provided between 6 and 6.

As described above, the western umbrella shown in FIG.
is automatically moved upward on the umbrella handle by the force of the coil spring 14, and since it has a top-press type umbrella structure, the base bone 7, strut 8, master rib 9, and support bone 10 are automatically moved upward on the umbrella handle. Furthermore, the tip rib 11 is automatically expanded and rotated by the pulling action of the advancing/retracting rod 12, and the open height shown in the right half of Fig. 1 is finally obtained. ing. In addition, when holding the lower potter's wheel 6 and pulling it down on the umbrella handle from the same open state, the base bone 7, the strut 8, the main rib 9, and the supporting bone 1, since it has a top press type umbrella structure,
0 automatic folding and rotation is obtained, and then by folding the tip bone 11, the extended and folded state of the umbrella handle shown in the left half of FIG. 1 is obtained. Of course, when carrying it normally, the umbrella handle is further shortened.

As shown in Figures 1 and 2, the position of the lower potter's wheel 6 on the umbrella handle in the open state is set above the lower end of the upper handle 1, and in such a position, the lower potter's wheel 6 is placed on the umbrella handle. A locking piece 15 is provided in the upper end of the inner handle 2 to lock the handle so that it cannot move upwardly and to maintain the closed state of the umbrella. As shown in FIG. 2, this locking piece 15 is supported 16 by the inner handle 2 at the upper end, and a locking protrusion 15a at the lower end is pushed out of the umbrella handle by a spring 17 provided inside the inner handle 2. It is energized to move in the direction of protrusion. Window holes 2a, 1a are formed in the middle handle 2 and upper handle 1, which overlap when the umbrella handle is extended, and the locking piece 15 passes through these windows 2a, 1a by the force of the spring 17, and locks into the locking protrusion 15a. protrudes to the outside of the upper handle 1 and engages with the inner surface of the lower end of the lower lower wheel 6 in the umbrella closing position, thereby locking the lower lower wheel 6 so that it cannot move upward.

In order to release the locking piece 15 described above by manual operation, an operating piece 19 is provided on the lower handle 3 at an appropriate amount above the handle 18 fixed to the lower end of the lower handle 3.
