Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic opening type Western umbrella, and particularly relates to an improvement of the push-in button for opening the umbrella provided on the automatic opening type Western umbrella.

[Conventional technology]

Conventionally, automatic opening type Western umbrellas have a lower potter's wheel, which is biased in the upward direction by a spring, releasably engaged with a flip provided on the center rod, and the engagement is achieved by pushing the push-in end of the flip. It is configured to release the lock and raise the lower wheel, and a push button is provided at the push end.

The mounting position of the push-in button varies depending on the type of Western umbrella. For example, the push-in button is recessed in the hand (Utility Model Application No. 52-129567, Utility Model Application No. 51-49656).
No.) or a push-in button embedded in a cylindrical decorative cover (Utility Model Application No. 51-67163) is known.
In any of these cases, since the push-in button is arranged at a position away from the tip of the main rib, the push-in button does not interfere with the main rib in any way.

However, there are Western umbrellas in which the push-in end of the flip-flop is placed on the exposed part of the center rod between the lower potter's wheel and the handle when the umbrella is closed, and a push-in button is provided at the push-in end (hereinafter referred to as a "protruding button-type Western umbrella"). In this case, when the umbrella is closed, the tips of the main ribs are focused on the outer periphery of the exposed portion of the center rod, and as a result, the push-in button interferes with the main ribs.

[Problem that the invention attempts to solve]

In the above-mentioned "Western umbrella with a protruding button", there is a problem that the tips of the main ribs interfere with the push-in button in the closed state and the umbrella is not properly focused. In particular, the ribs that interfere with the push-in button are pushed to both sides of the push-in button, and as a result, the problem arises that the tips of the group of ribs that are to be focused are poorly accommodated.

To solve this problem, in order to improve the design effect of Western umbrellas, we introduced a type of Western umbrella in which a tip body with a diameter larger than that of the main rib was attached to the tip of the main rib (hereinafter referred to as a ``Western umbrella with a large diameter point type''). It becomes even more noticeable in some cases.
In other words, in the case of this "Western umbrella with a large diameter canopy",
When the large-diameter dew tip bodies are focused on both sides of the push-in button when the umbrella is closed, interference between the dew tip bodies and the push-in button becomes noticeable.

[Means for solving problems]

In ``Western umbrellas with a protruding button type'' and ``Western umbrellas with a large diameter tip,'' in order to make the tip tip of the main rib group fit well as a whole when the umbrella is closed, it is necessary to The amount of interference with the button must be minimized. However, from the viewpoint of operability, the finger pressure surface of the push-in button must have a sufficient area. For this reason, the means constituted by the present invention is that both side walls of the push-in button along the tip body are formed into tapered surfaces that gradually narrow from the acupressure surface to the bottom surface. This tapered surface allows
The tip body of the main rib group can be satisfactorily housed. That is, to illustrate this point, for example, if the push-in button 11 does not have anything corresponding to the tapered surface, the tips 9 of the 8 groups of main ribs (outer tip body) in the closed state as shown in FIG. ) interferes with both side walls of the push-in button 11 and is not properly focused, and in particular, the tip of the main rib 9 (the tip body) of the part that interferes with the push-in button 11 is pushed to both sides of the push-in button 11, The tip of the main rib group to be focused is deviated and the structure is poor, whereas in the present invention, as shown in FIG.
(The tip body) fits well.

〔Example〕

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

As shown in FIGS. 6 and 7, the Western umbrella of the present invention has an exposed portion 4 of a center rod 3 located between the lower potter's wheel 1 and the handle 2 when the umbrella is closed. A push-in end 5 is projected from the circumferential surface of the exposed portion 4, and a push-in button 11 is fixed to the push-in end 5. Therefore, this constitutes the above-mentioned "protruding button type western umbrella". The lower potter's wheel 1 is biased in the upward direction along the middle rod 3 by a spring (not shown), and when the umbrella is closed, the lower potter's wheel 1 is locked to the locking pawl 7 of the flip 6, and from this state the flip 6 is lifted. When the pushing end 5 is pushed to release the locking by the locking claw 7, the umbrella is automatically opened.

The tips 9 of the main ribs 8 extend beyond the lower potter's wheel 1 when the umbrella is closed, and are focused around the outer periphery of the exposed center rod portion 4. Roundness (as long as it is round, it is fine, and it does not necessarily have to be hemispherical as shown)
The tip body 10 having the following is attached. That is, when the umbrella is closed, at least a portion of the tip body 10 in the longitudinal direction is focused to the side of the push-in button 11. Therefore, this constitutes the above-mentioned "Western umbrella with a large diameter tip".

A push button 11 attached to the flip push end 5
is molded, for example, from synthetic resin, and the shape of the button 11 in plan view is arbitrary, such as an elongated octagon, an elongated hexagon, a rectangle, or an oval.

As shown in FIGS. 1 to 4, this push-in button 11 has a bottom surface 12 facing the repelling push-in end 5, and an acupressure surface 13 on the opposite side of the bottom surface, and has a groove formed in the bottom surface 12. 14, the repelling push-in end 5 is inserted and fixed. At this time, for example, if the size of the groove 14 is made slightly smaller than the push-in end 5 to be inserted, the push-in end 5 can be press-fitted into the groove 14 and securely fixed.

In addition, the push-in button 11 has both side walls along the tip body 10 that is focused when the umbrella is closed formed into a tapered surface 18 that gradually narrows from the acupressure surface 13 toward the bottom surface 12. The front and rear walls 19 of No. 11 are also formed into similar tapered surfaces.

The drawings show a recess 15 formed in the acupressure surface 13 of the push-in button 11, and a decorative material 16 inserted into the recess 15. This decorative material 16 is made of a synthetic resin plate, which is fitted into the recess 15 and adhered.A medium-height bulge is provided on the upper surface of the plate, and mesh-like striations 17 are applied to form an anti-slip means. However, it is also possible to mold the push-in button 11 and the decorative material 16 at the same time. Further, after molding the push-in button 11 with the recess 15 formed therein, it is also possible to solidify the filler filled in the recess 15 to form the decorative material 16. The color or pattern of this decorative material 16 can be harmonized with the color of the fabric of the western umbrella, the canopy body 10, etc.

However, in the present invention, such a concave portion 15 and a decorative material 16 are not essential to the invention, and as an embodiment of the push-in button 11, the acupressure surface 1 is simply
Please understand that anything having 3 is sufficient.

[Effect of idea]

As a result of the above-mentioned configuration of the present invention, a "Western umbrella with a large diameter tip" is created, and the design effect of the entire umbrella can be improved by the tip body 10 having a large diameter and a rounded tip. Furthermore, since the tip of the main rib 8 is protected by the tip body 10, there is no danger of injuring neighbors by the sharp tip of the main rib 8 when the umbrella is automatically opened.

In addition, this invention is a ``Western umbrella with a protruding button'',
Since the push-in end 5 is arranged in the exposed part of the middle rod 3 located between the lower potter's wheel 1 and the handle 2, the structure is simple and can be manufactured at low cost.

Therefore, since it is a "Western umbrella with a protruding button type" and a "Western umbrella with a large diameter tip" as described above, the large diameter tip body 10 interferes with the push-in button 11 when closing the umbrella. In contrast, in the present invention, the push-in button 11 forms both side walls along the tip body 10 into tapered surfaces 18 that gradually narrow from the acupressure surface 13 toward the bottom surface 12. The amount of interference between the tip bodies 10 of the main ribs and the push-in button 11 can be reduced, and the fitting of the tip bodies 10 of the eight groups of main ribs can be made good.

In addition, in order to improve the operability of the push-in button 11, the acupressure surface 13 of the push-in button 11 must have a sufficient area. Since the area of the acupressure surface 13 can be increased while minimizing interference with the acupressure surface 10, operability is also excellent.
