Description

[Detailed description of the invention] [Industrial application field] TECHNICAL FIELD The present invention relates to improvements in automatic opening type Western umbrellas.

[Conventional technology]

Conventional automatic-opening Western umbrellas have a central rod with a hand at the tail, an upper potter's wheel that pivots the main rib, a sliding middle potter's wheel that pivots the supporting bone, and a sliding lower potter's wheel that pivots the child bone. There is a known one in which a spring is inserted between the middle potter's wheel and the lower potter's wheel to urge them apart, and a repellent is provided on the middle rod to releasably lock the lower potter's wheel when closing the umbrella. It is. Therefore, when the umbrella is closed, by pushing the push button of the repellent, the lower and middle potter's wheels, which are released from the locked state of the repellent, are raised by the spring, and the umbrella is automatically opened.

By the way, in addition to the above-mentioned configuration, there is also known a device that is provided with a tip receiver that holds the tip of the condensed main rib when the umbrella is closed. This dew point receiver is located on the hand side and is slidably inserted into the middle rod.
The dew tip receiver is made to slide forward against the focused dew tips of the main ribs, and the dew tip receiver is always biased in the backward direction by a spring, and when in the forward position, it is not exposed to the repellent. It is something that is locked. Therefore, when this dew tip receptor does not exist, the ribs do not completely converge when the umbrella is closed, and are in a slightly open state, resulting in the inconvenience of binding the ribs with a tape-like band. However, with the advent of the dew tip receiver, it has become easy to completely focus the main ribs using the dew tip receiver when the umbrella is closed. Moreover, when closing the umbrella, when you press the push button of the hatchet, the dew point receiver first moves back and releases the hold of the dew point of the main rib, and then the lower potter's wheel releases the lock and opens the umbrella. There is a convenience that can be done automatically.

[Problem that the invention seeks to solve]

However, in the conventional automatic opening type Western umbrella equipped with the above-mentioned dew tip receiver, the dew tip receiver is formed in a bowl shape and is configured to be slidable on the center rod, and also has the above-mentioned features. It incorporates a spring for retraction, and requires a complicated structure in a narrow space, making it difficult to assemble.

In addition, when holding the dew tip with the dew tip receiver, hold the converged dew tip group of the main rib with one hand,
The tip receiver must be slid with the other hand, which is not always easy.

In addition, in recent years, the diameter of the tip at the tip of the rib has become larger in order to improve the safety and decorative effect of automatically opening Western umbrellas. Accordingly, the size of the dew tip receiver has to be increased, but it is not aesthetically pleasing to move the large dew tip receiver back and forth.

[Means for solving problems]

The purpose of the present invention is to provide an automatic opening type Western umbrella that solves the above problems, and the conventional automatic opening type Western umbrella equipped with a dew tip receiver has a dew tip receptacle. Whereas the objective was achieved by moving the receiver back and forth, we changed our thinking and adopted a method of fixing the dew tip receiver while moving the main rib to insert the dew tip into the dew tip receiver. By doing so, the above problem could be solved. The means of the present invention is that an upper potter's wheel for pivoting the main bone, a sliding middle potter's wheel for pivoting the supporting bone, and a sliding middle potter's wheel for pivoting the coronal bone are attached to the middle rod with a hand provided at the tail. A sliding lower potter's wheel is placed between the middle potter's wheel and the lower potter's wheel, a spring is interposed between the middle potter's wheel and the lower potter's wheel to bias them in the direction of separation, and a repellent is provided on the middle rod to releasably lock the lower potter's wheel when closing the umbrella. In an automatic opening type Western umbrella consisting of: The upper potter's wheel is provided with a moving mechanism that allows it to move freely in the axial direction of the center rod, and also includes an elastic mechanism that constantly urges the upper potter's wheel upward; A dew point receiver is provided which opens upward; when the umbrella is closed, the upper potter's wheel is lowered through the moving mechanism against the springing mechanism, and the tip of the converged rib is inserted into the dew point receiver. , is provided with a removable locking mechanism that prevents the upper wheel from moving upward.

〔Example〕

Embodiments of the present invention will be described in detail below based on the drawings.

(First Embodiment) In the first embodiment shown in FIGS. 1 to 4, the middle rod 1 has a stone prong 2 on the tip side and a handle 3 on the tail.
is firmly attached. An upper potter's wheel 4, a middle potter's wheel 5, and a lower potter's wheel 6 are arranged sequentially from the tip side of the middle rod 1 toward the tail. The base end of the main rib 7 is pivotally attached to the upper potter's wheel 4. The proximal end of a support bone 8 is pivotally attached to the middle potter's wheel 5, and the tip of the support bone 8 is pivotally attached to the midway portion of the master rib 7. A cochlear bone 9 is pivotally attached to the lower potter's wheel 6, and the tip of the cochlear bone 9 is pivotally attached to the midway portion of the support bone 8.
A jump spring 10 is interposed between the middle potter's wheel 5 and the lower potter's wheel 6 to bias them in the direction of separation.
On the proximal side of the middle rod 1, there is installed a repellent 12 that removably locks the locking hole 11 of the lower potter's wheel 6 when the umbrella is closed. This repellent 12 is equipped with a push button 13. In addition, 7a is an umbrella cloth. The above configuration is
This is similar to a conventionally known automatic opening type Western umbrella.

In the present invention, the upper potter's wheel 4 includes a moving mechanism 14 that is movable in the axial direction of the center rod 1, and a resilient mechanism 15 that always urges the upper potter's wheel 4 upward.

The moving mechanism 14, as shown in FIG. 2a,
A cylindrical body 16 slidably fitted onto the tip of the middle rod 1
An upper potter's wheel 4 is fixed to the cylindrical body 16 with a pin, and the stone protrusion 2 is externally fitted and fixed to the cylindrical body 16 at a position above the upper potter's wheel 4. Also,
The cylindrical body 16 has a long hole 17 formed in the axial direction, and a guide pin 18 fixed to the tip of the inner rod 1 is inserted into the long hole 17.
I will guide you to.

The elastic mechanism 15 includes a compression coil spring 1
9, the spring 19 has a stopper 20 fixed to the center rod 1 with a pin, and the cylindrical body 16.
It is interposed between the lower end of

Further, in the present invention, a tip receiver 21 that opens upward is provided on the hand side. In this embodiment, the tip receiver 21 is formed integrally with the handle 3 and has a bowl-shaped opening edge 22.

Furthermore, in the present invention, as will be described later, when the umbrella is closed, the upper potter's wheel 4 is moved via the moving mechanism 14 to the resilient mechanism 1.
The tip 2 of the main rib 7 is lowered against the force 5 and focused.
A detachable locking mechanism 24 is provided to prevent the upper potter's wheel 4 from moving upward in a state where it is inserted and held in the tip receiver 21. In this embodiment, the locking mechanism 24 includes an auxiliary claw piece 25 formed on the repellent 12.
Configure. That is, as shown in FIG. 2b, the repellent 12 is inserted into the middle rod 1, and two claw pieces, the opening/closing claw piece 26 and the auxiliary claw piece 24, are protruded from the slit of the middle rod 1. ing. The push button 13 is fixed to an extension of the repellent 12 and is embedded in the handle 3.

(Operation of the first embodiment) To explain the operation of the first embodiment, in order to close the umbrella, the lower potter's wheel 6 is moved along the center rod 1 from the states shown in FIGS. 1 and 2, a and b. Then, lower the lower potter's wheel 6 so that the locking hole 11 of the lower potter's wheel 6 is locked with the opening/closing claw piece 26 of the repellent 12. During this operation, since the cylinder 16 is urged upward by the spring 19, the upper potter's wheel 4 does not descend. Opening/closing claw piece 26
Due to the locking, the western umbrella maintains a closed state, and the tip of the main rib 7 is in a slightly open state with respect to the middle rod 1.

From this state, as shown by the chain line in Figure 3b,
After converging the 7 groups of main ribs, connect the 7 groups of main ribs to the middle rod 1
As shown in FIGS. 4a and 4b, the upper potter's wheel 4 descends against the resilient mechanism 15 through the moving mechanism 14, and as a result, the main ribs 7 also move toward the upper potter's wheel 4. At the same time, the dew tip 23 is lowered and inserted into the dew tip receptacle 21. At this time, between the upper potter's wheel 4 and the lower potter's wheel 6, the main rib 7 and the supporting bone 8 are in an expanded state, so the lower potter's wheel 6 also descends following the upper potter's wheel 4, The locking hole 11 of the potter's wheel 6 is locked to the auxiliary claw piece 25 of the repellent 12. That is, the upper potter's wheel 4 is prevented from moving upward by the locking mechanism 24 that constitutes the auxiliary claw piece 25 via the lower potter's wheel 6, the support rib 8, and the main rib 7, and the dew point 23 is held in place by the dew tip receiver. The state of being held within the body 21 is maintained. Therefore, in the first embodiment, the elongated hole 1 of the cylindrical body 16 is
The length of 7 corresponds to the distance between the opening/closing claws 26 and the auxiliary claws 25 of the repellent 12, or is slightly larger than the distance between the claws. There is.

Contrary to the above, in order to open the western umbrella, it is sufficient to simply push the push button 13 of the hatchet 12. By this pushing operation, the lower wheel 6 in FIGS. 4a and 4b is released from the auxiliary claw piece 25, and as a result, the upper wheel 4
is raised by the resilient mechanism 15 as shown in FIG. 3a, and the tip 23 together with the main rib 7 pops out of the tip receiver 21 as shown in FIG. 2b. Furthermore, push button 13
If the pushing operation continues, the opening/closing claw piece 26 of the repellent 12 will not be locked in the locking hole 11 of the lower wheel 6, or will be immediately released even if it is once locked, and the lower wheel will be closed by the jump spring 10 as in the conventional case. 6 and the middle potter's wheel 5 rise along the middle rod 1 to automatically open the umbrella.

(Second Embodiment) In the second embodiment shown in FIG. 5, a repellent 12 equipped with a push button 13 is provided at a position away from the hand 3. The dew tip receiver 21 is formed separately from the handle 3 and has a tapered shape with an opening edge widened.
In this embodiment, the main rib 7 is formed to be slightly longer than in the first embodiment.

(Modified Embodiments) In addition to the first and second embodiments described above, various other modified embodiments are possible. 26
It is free to install it in a separate dedicated repellent without having to install it in parallel. In addition, this locking mechanism 24 locks the lower potter's wheel 6 as well as the moving mechanism 1 of the upper potter's wheel 4.
4 can be directly locked in a detachable manner, and the unlocking can be remotely controlled.

〔Effect of the invention〕

As a result of the above configuration, the present invention is configured such that the tip receiver itself is slidable relative to the center rod as in the past, and a spring for retracting is incorporated into the tip receiver, making it possible to save space in a narrow space. Unlike those with a complicated structure, the tip receiver 21 is configured to be fixed on the hand side, while the moving mechanism 14 and the rebound mechanism 15 are fixed.
Since the mechanism is arranged on the upper potter's wheel side, assembly is easy due to the distributed arrangement of the mechanisms.

In addition, when the dew tip is held by the dew tip receiver, the group of condensed main ribs is held in hand, and the group of dew tips is immediately exposed by pulling the main rib group toward the hand side while being held. Since it can be held within the prereceptor, its operation is extremely easy.

In addition, with regard to the recent trend of holding large-diameter dew tips, it is sufficient to simply increase the size of the dew tip receiver accordingly, and what is more, this enlarged dew tip receiver can be moved back and forth. Since the structure is fixed and not fixed, the appearance will not be spoiled.
