Description

[Detailed description of the invention] TECHNICAL FIELD The present invention relates to an automatic opening Western umbrella without a wick.

As shown in Fig. 9.10, a typical example of commercially available automatic opening umbrellas is such that the repellent (1), which is made of a punched piece of metal plate, exerts a so-called lever effect on the hollow interior of the central rod (2). The slit (3) in the center rod (2)
The claw part (4) of the repellent (1) protruding from the center 45 (2)
), by the locking action with the lower potter's wheel (5) fitted in the
The closed state is maintained for N1 times.

Then, when the claw 01'1 (4) is pushed into the middle rod (2) using the button (G) of the repellent, the lower potter's wheel (5) and the middle potter's wheel (7 ] Generally, the umbrella is automatically opened by raising both the potter's wheel (5) and (7) by the tension of a compression coil spring (8) interposed between the two.

However, with this, there is a needle inside the hollow part of the middle stick (2)! Since the key (1) has to be assembled, the assembly process is extremely complicated. Moreover, since the inner frame (2) has a slit (3) for the appearance and retrieval of the bar (C1), the inner rod (2) Its own strength decreases, and the middle rod (2) tends to bend, especially from the closed position of the slit (3), and the slit (3) and the claw part (4) of the repellent (1) Because the outer layer is exposed, the overall appearance of the Western umbrella may be hindered from being fashionable.

The present invention aims to solve these problems, and its specific configuration is illustrated in the figure! The detailed explanation based on the three cases is as follows.

That is, first of all, Figures 1 to 5 show the basic example of the present invention, and (A) is the fixed hand body of the western umbrella, with the middle 1 (10
) and a handle (11) fixed to the bottom thereof. (12) and (13) are a middle potter's wheel and a lower potter's wheel that are fitted in the middle of the center rod (10) so that they can be raised and lowered,
It goes without saying that the umbrella ribs are pivotally connected to these by known means.
) While interposed between the upper and lower parts of (13), the middle 46 (
10) A compression coil spring mounted on the top, which always biases both potter's wheels (+2) (13) in the upward direction so that they automatically open.

This is why it is called the automatic opening type of Western umbrella.

(!5) is the required number of contact pieces carved like sawtooth on the lower end of the lower [1 black (13)], and has a hanging part that can come into contact with the umbrella-closing cam surface of the rotating ring mentioned above. in a state. Its contact piece (
15) are suspended from the lower end of the opening of the lower potter's wheel (13) in a so-called circular arrangement.
Therefore, no matter how the rotation angle of the rotation ring changes, the abutment piece (15) is always in contact with the umbrella closing cam surface. As long as contact is possible, the number and arrangement of the contact pieces (15) to be installed are free.

In addition, (IC) is also an island with a required number of flange-shaped locking claws that continuously extend outward from near the lower end of the lower potter's wheel (13), and in the example shown, it is located on the diameter line of the lower potter's wheel (13). In the figure, they are arranged as a pair facing each other, but the number and arrangement form of the arrangement can also be set appropriately.

On the other hand, on the upper part of the handle (11) in the fixed hand body (A), there is a cover r which itself forms a part of the handle (11).
II (17) is fixedly installed, and a freely rotatable rotating ring (18) for receiving a lower potter's wheel is fitted into the cover tube (17). (19) is a required number of flange-shaped claw receivers that continuously extend inward from the upper end of the opening of the rotating ring (18), and are connected to the above-mentioned locking claw (16) of the lower potter's wheel (13). In the vertical positional relationship, they engage each other in a detachable manner. (20) is a relief notch for releasing the locking action, and the claw receiver (19)
It is recessed and fixed relative to the overhang. In this regard, in the case of the illustrated example, the pawl receivers (19) and relief notches (20) are arranged in a radially symmetrical manner with four pieces each, which are more than the locking pawls (16), but their arrangement form and installation After all, the number can be determined freely. The locking claw (16) and its claw receiver (1
The form of 9) is not limited to the above-mentioned 87-piece type.

Furthermore, (21) is a required number of umbrella-closing plate cams that are integrally projected from the inner surface of the body of the rotation ring (18), and the inclined cam surface (a) on which they act is in contact with the lower potter's wheel (13). This piece (15)
When faced with 131, the a-worker [(18)
It rotates by itself, and the pawl receiver (19) engages with the locking pawl (16) of the lower potter's wheel (13). In other words, when the lower potter's wheel (13) is lowered, the umbrella is fixedly held in the closed state via the rotating ring (18) that automatically rotates.

In the illustrated example, the plate cams (21) are a pair facing each other on the diameter line of the rotating ring (18), and the cam surface (a)
is determined as a triangle that forms the fl slope surface, while the lower potter's wheel (1
Although the abutment piece (15) in 3) is also formed in the shape of a triangular claw, it may be of any other form or function as long as it can cause the above-mentioned automatic turning action. The rotation angle (θ) of the II ring (18) also depends on the locking claw (16) and the claw receiver (19).
), it can be set appropriately. (22) is a stopper tube for the rotating ring (18), and is fixed to the center 46 (10).

(23) is the same number of plate cams for opening the umbrella that are integrally sunk into the outer surface of the body of the first gear ring (18), and the inclined cam surface (b) on which they act has a slide operation for opening the umbrella. button (24
) are installed so that they engage. In other words, is the operation button (24) covered? J (17) through the slide guide elongated hole (25) and the engagement piece (
26) is introduced and installed so as to engage with the cam surface (b), and soon the finger rest piece (27) is inserted into the cover tube (1).
7) is exposed to the outside. Of course, the operation button (24) may have an annular shape surrounding the cover tube (17).

When the button (24) is slid from the outside of the cover tube (17), the rotation F17 ring (18) automatically moves to Ii! due to the action of the cam surface (b). Then, the locking action between the pawl receiver (19) and the locking pawl (16) of the lower potter's wheel (13) is released, and the umbrella opens automatically and instantaneously. In addition, the rotating ring when closing the umbrella (!8)
The direction of rotation may be opposite to that when closing the umbrella,
Further, as long as the locking action between the locking claw (1G) and its claw receiver (19) can be released, the same forward direction may be used.

Nos. G to 8 show modified examples of the present invention, which achieve the same purpose as the basic example described above, but have the following configurations that are partially different from the basic example.

That is, numeral (28) represents four umbrella-closing groove cams formed on the inner surface of the body of the rotating ring (18), which also have an inclined cam surface (c). (29) is an elevating plate that engages with the full cam (28), and is fitted into the middle II (10) so that it can only rise and fall, and is also pushed up by a compression coil spring (30) from below. is receiving force.

When the lower potter's wheel (13) is lowered, the lifting plate (29) that comes into contact with it lowers, and the l1li
The I-ring ring (18) rotates on its own, and the umbrella is kept in a closed state where its claw receiver (19) and the locking claw (16) of the lower potter's wheel (13) engage. ing.

In the above basic example, the umbrella closing plate cam (2) of the rotating ring (I8) is
) The lower potter's wheel (13) is brought into direct contact with the rotating ring (18).
), so to speak, make indirect contact with it, and make a J-ring (1) around it.
8) is automatically rotated. Since the structure and operation of the bar are substantially the same as the basic example above, 'I
In FIGS. AG to 8, the corresponding symbols with those in FIGS. 1 to 5 are only written, and detailed explanation thereof will be omitted.

(In any case, the above configuration of the present invention has the effect of completely solving the problems of the conventional automatic opening type umbrella mentioned at the beginning. In other words, the cover tube ( 17) is fixedly installed, and a rotating ring (18) for receiving a lower potter's wheel (18) that engages and engages the lower potter's wheel (13) in a detachable manner is fitted inside the lower potter's wheel (13). There is no need for any troublesome installation work into the center rod, and since the center rod does not have any perforations such as slits for installing the repellent or retraction, there is a risk of the center rod becoming bent or having a lower strength. This means that the appearance and cosmetic effect of the Western umbrella can be significantly improved.

Moreover, the body of the lower potter's wheel receiving rotary yJ (18) is provided with two types of cam surfaces (a) and (c) for closing the umbrella and a cam surface (b) for opening the umbrella. Umbrella cam surface (a) (c
) to the lower potter's wheel (13) directly or with a separate lifting plate (2
9), the rotating ring (18) automatically rotates and locks with the locking pawl (16) of the lower potter's wheel (13). Since the lower potter's wheel (13) is held in this position, Usamo can close it easily and efficiently by simply squeezing the lower potter's wheel (13) with his fingertips and pulling it down. be.

On the other hand, when opening the umbrella, grasp the handle (11)!
By sliding the operation button (24) one step ahead of Nashisaku, it is possible to open the umbrella for FI5 flight. The operation button (24) is
