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 type Western umbrellas have one 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. A spring is inserted between the middle potter's wheel and the lower potter's wheel to bias them in the direction of separation.

It is known that the center rod is provided with a repellent that detachably locks the lower wheel when the umbrella is closed. Therefore.

By pressing the push button of the hatchet when closing the umbrella.

The lower potter's wheel and the middle potter's wheel, which are released from the locking state of the repellent, are raised by the spring to automatically open the umbrella.

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 one hand side and is slidably inserted into the middle rod, and is used to slide the dew point receiver forward against the focused dew point of the master rib. The first receiving body is always biased by a spring in the backward direction, and is locked to the repellent in the forward position. 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, which causes the inconvenience of binding the ribs with a tape-like band. With the appearance of the dew point receiver, it became easy to completely focus the main ribs using the dew point receiver when the umbrella was closed. In addition, when closing the umbrella, when the push button of the repellent is pushed, 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 is released and the umbrella is opened. 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 provided with the above-mentioned dew tip receiver, the dew tip receiver is formed into a bowl shape.

It is configured to be slidable on the center rod, and furthermore.

It incorporates a spring for retraction as described above, and requires a complicated structure in a narrow space.

Difficult to assemble.

In addition, when holding the dew tip with the n-tip receiver, it is necessary to hold the condensed tip group of the main rib with one hand and slide the dew tip receiver with the other hand, which is not always easy. isn't it.

In addition, in recent years, in order to improve the safety and decorative effect of automatically opening Western umbrellas, there has been a trend toward larger diameter tips at the tips of the ribs.
In order to hold this large-diameter dew tip, the dew tip receiver must also be enlarged accordingly, but moving the large dew tip receiver back and forth makes it difficult to change the appearance of the dew tip. is not good.

[Means for solving problems]

An object of the present invention is to provide an automatic opening type Western umbrella that solves the above problems.

Conventional automatic-opening Western umbrellas equipped with a dew tip receiver achieved their purpose by moving the dew tip receiver back and forth relative to the a-bone. While fixed,
The above-mentioned problem could be solved by adopting a means of moving the main rib and inserting the exposure light into the exposure point receptor. Therefore, the following two points are the means of the present invention.

For the middle rod with a handle on the tail, there is an upper potter's wheel that pivots the main bone, and a sliding middle potter's wheel that pivots the support bone.

A sliding lower potter's wheel is arranged to pivot the coronal bone, and a spring is interposed between the middle potter's wheel and the lower potter's wheel to bias them in the direction of separation.
In an automatic opening type Western umbrella in which the middle rod is provided with a reel for releasably locking the lower potter's wheel when closing the umbrella; Equipped with a springing mechanism that urges the upper potter's wheel upward; A tip receiver that opens upward is provided on the proximal side of the middle rod; When the umbrella is closed, the upper potter's wheel is lowered against the springing mechanism via a moving mechanism. The present invention is characterized in that a removable locking mechanism is provided to prevent the upper potter's wheel from moving upward in a state where the tip of the converged master rib is inserted into the tip receiver.

〔Example〕

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

(First example) In the first embodiment shown in FIGS. 1 to 4.

The middle rod 1 has a stone protrusion 2 arranged on its tip side and a handle 3 fixed to its tail. From the tip of the middle rod 1 to the tail, turn the upper potter's wheel 4. Middle potter's wheel 5. A lower potter's wheel 6 is arranged. 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 a tip of the coccyx bone 9 is pivotally attached to a 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, and the locking hole 11 of the lower potter's wheel 6 can be freely engaged and detached on the proximal side of the middle rod 1 when closing the umbrella. A repellent 12 that locks into the housing is installed inside. This Hajiki 1

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 is as shown in FIG. 2(a).

A cylindrical body 16 is slidably fitted onto the tip of the middle rod 1, and an upper potter's wheel 4 is fixed to the cylindrical body 16 with a pin. 16, said stone end 2
is fixed on the outside.

Further, the cylinder 16 has a long hole 17 formed in the axial direction.

The guide pin 18 fixed to the tip of the middle rod 1 is inserted into the elongated hole 1.
I will guide you to 7.

The elastic mechanism 15 comprises a compression coil spring 19, and the spring 19 is interposed between a stopper 20 fixed to the middle rod 1 with a bottle and the lower end of the cylindrical body 16.

Further, in the present invention, a tip receiver 21 that opens upward is provided on the second 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 one aspect of the present invention, as will be described later, when the umbrella is closed, the upper potter's wheel 4 is lowered through the moving mechanism 14 against the springing mechanism 15, and the condensed tips 23 of the converged main ribs 7 are moved to the tip receiver 21. A detachable locking mechanism 24 is provided to prevent the upper potter's wheel 4 from moving upward when it is inserted and held by the upper potter's wheel 4. In this embodiment, the locking mechanism 24 constitutes an auxiliary claw piece 25 formed on the repellent 12. That is, as shown in FIG. 2(b),
The repellent 12 is charged into the middle rod 1.

Two claw pieces, an opening/closing claw piece 26 and the auxiliary claw piece 24, protrude from the slit of the center rod 1.

Note that the push button 13 is fixed to an extension of the repellent 12 and is embedded in one hand 3.

(Operation of the first embodiment) To explain the operation of the first embodiment, in order to close the umbrella, from the state shown in Figs. 1 and 2 (al (b)), move the lower wheel 6 to the center bar Descend along the line.

The locking hole 11 of the cough potter's wheel 6 is connected to the opening/closing claw piece 2 of the repellent 12.
Lock at 6. During this operation, the cylindrical body 16
Since the upper potter's wheel 4 does not descend, the umbrella maintains its closed state due to the locking of the opening/closing claw piece 26, and the tip of the main rib 7 is held against the middle rod 1. It is slightly open.

From this state, as shown in the chain line in Fig. 3 (bl).

After converging the 7 groups of main ribs, when the 7 groups of main ribs are pulled toward the hand side with respect to the middle rod 1, the upper potter's wheel 4 is moved through the moving mechanism 14, as shown in FIGS. 4(a) and 4(b). It descends against the generating mechanism 15, and as a result, the master rib 7 group also descends together with the upper potter's wheel 4, and the dew point 23 is inserted into the dew point receptacle 21. At this time, between the upper potter's wheel 4 and the lower potter's wheel 6, the main rib 7
Since the supporting bones 8 are in the expanded state, the lower wheel 6 also descends following the upper wheel 4, and the locking hole 11 of the lower wheel 6 is closed.
is locked to the auxiliary claw piece 25 of the repellent 12. That is, by the locking mechanism 24 that constitutes the auxiliary claw piece 25, the lower wheel 6.
Spine 8. The upper potter's wheel 4 is prevented from moving upward via the main rib 7, and maintains the tip 23 held within the tip receiver 21. Therefore, in the first embodiment, the length of the elongated hole 17 of the cylinder 16 is set to correspond to the distance between the opening/closing claws 26 and the auxiliary claws 25 of the repellent 12. , or a dimension slightly larger than the interval dimension between the claw pieces.

Contrary to the above, to open a Western umbrella, simply use Hajiki 12
By pushing the push button 13, the lower wheel 6 shown in FIG. ), the tip 23 is raised by the springing mechanism 15, and the tip 23 along with the main rib 7 pops out of the tip receiver 21 as shown in FIG. The 12 opening/closing pawls 26 do not lock in the locking hole 11 of the lower potter's wheel 6, or are immediately released even if they are once locked, and the lower potter's wheel 6 and the middle potter's wheel 5 are moved to the center rod by the jump spring 10 as in the conventional case. 1 and automatically opens the umbrella.

(Second Embodiment) The second embodiment shown in FIG.
2 is provided at a position away from the hand 3, and the dew tip receiver 2
1 is formed separately from the 1 hand 3, and the opening edge is formed into a widened and tapered shape. 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, nine other modified embodiments are possible. Without being installed in parallel with 26,
It is free to install it in a separate dedicated repellent. In addition, this locking mechanism 24 locks the lower wheel 6 as well as the upper wheel 4.
It is also possible to configure the moving mechanism 14 to be directly lockable and detachable, and to be able to release the lock by remote control.

〔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 fixed on the hand side, while the moving mechanism 14 and the springing mechanism 15 are arranged on the upper potter's wheel side.
Since the mechanisms are distributed, assembly is easy.

In addition, when the dew tip is held by the dew tip receiver,
Hold the cluster of condensed ribs in your hand.

By pulling the main rib group toward the hand side while holding it, the tip group can be immediately held in the tip receiver, so the operation is extremely easy.

In addition, in order to accommodate large-diameter dew tips, which has been a trend in recent years, it is sufficient to simply increase the size of the dew tip receiver accordingly.
Moreover, since this large-sized dew tip receiver is not moved back and forth but has a fixed structure, it does not spoil the appearance.
