BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a western umbrella having a wooden center rod and a plastic hand (handle), and more particularly to a mounting structure for the plastic hand.

[0002]

2. Description of the Related Art When attaching a plastic hand to a wooden center rod, the center rod insertion hole provided at the hand and the end portion of the center rod inserted into this are bonded and fixed with an adhesive. The method is common. However, there is currently no adhesive that can firmly bond wood products and plastic products together, so even if they are adhesively fixed, they can be suspended for a long time by hanging them on a bar or the like. There is a high possibility that the center rod will fall out of your hand when you shake your umbrella with your hand to drain or drain water, and there has been a strong demand for improvement. Of course, if you mechanically fix your hand to the center rod with a fastener such as a nail, there will be no problem in terms of mounting strength at the hand, but the end of the fastener is exposed on the surface of your hand, so you should hide it. However, it is not practical because it may increase the cost and adversely affect the design at hand.

The present invention has been made in order to solve the above-mentioned conventional problems, and its features are shown in parentheses with reference numerals of embodiments described later. To show, the western umbrella of the present invention is a western umbrella including a wooden rod (1), a plastic tubular body (4), and a plastic hand (6), and the wooden rod (1) is It has a small-diameter shaft part (3) extending from its free end (2) to an appropriate length, and the plastic cylindrical body (4) is fitted on the small-diameter shaft part (3) of the wooden middle rod (1) by a nail, It is fixed to the wooden center rod (1) with fasteners (5) such as tacks and pins, and the plastic hand (6) is externally fitted to the plastic tubular body (4) and the adhesive or solvent (8) is attached. It is characterized by being fixed by.

The plastic cylindrical body (4) is provided with a notch (9) in the lengthwise direction over the entire length so as to have a C-shaped cross section, or is divided into a plurality of pieces in the circumferential direction, and the fasteners are individually attached. It is also possible to fix it to the small diameter shaft part (3) of the center rod with (5). Further, in order to increase the adhesive strength with the hand (6), an uneven portion (10) can be formed on the outer peripheral surface, or a through hole (11) can be provided on the peripheral wall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a wooden center rod of a western umbrella, the free end of which is a free end (hand side mounting side). A small-diameter shaft portion 3 extending from the end portion 2 to an appropriate length is provided. Reference numeral 4 denotes a plastic cylindrical body having substantially the same length as the entire length of the small-diameter shaft portion 3 in the center rod 1, an inner diameter that allows the small-diameter shaft portion 3 to be externally fitted without great rattling, and It has the same outer diameter as the diameter. This plastic cylindrical body 4 is fitted onto the small-diameter shaft portion 3 of the center rod 1, and a fastening tool 5 (one or more) such as nails, tacks, pins or the like is made to have a small diameter from the outside of the cylindrical body 4. The cylindrical body 4 is fixed to the small-diameter shaft portion 3 by driving it into the shaft portion 3. At this time, the outer peripheral surface of the center rod 1 and the outer peripheral surface of the plastic cylindrical body 4 are substantially flush with each other.

Reference numeral 6 denotes a plastic hand, and at least one of the inner surface of the center rod insertion hole 7 and the outer peripheral surface of the plastic tubular body 4 is provided with the tubular body 4
When the adhesive or solvent 8 that is compatible with the adhesion of the plastics that form the
The end portion of the inner rod 1 (the portion to which the plastic tubular body 4 is fixed) is inserted into the inner rod insertion hole 7, and the plastic tubular body 4 and the plastic hand 6 are fixed to each other with the adhesive or solvent 8. are doing.

It should be noted that it is convenient for selecting an adhesive that the plastic cylindrical body 4 and the plastic hand 6 are formed of the same plastic material. Further, the tubular body 4 does not have to be a perfect tube as shown in FIG. For example, as shown in FIG.
It is also possible to form a tubular body 4 having a C-shaped cross-section with an axial slit 9 provided over the entire length, or as shown in FIG. 3, a plurality of gutter-shaped pieces 4a, 4b in the circumferential direction (see FIG. Although the example is divided into two, it may be three or more).

Further, in order to increase the adhesive strength between the plastic tubular body 4 and the plastic hand 6 by the adhesive or solvent 8, as shown in FIG. 4, a circumferential projection is formed on the outer peripheral surface of the tubular body 4. It is possible to form the uneven portion 10 such as a strip or groove, a large number of point-like projections or concave portions, or to form a large number of through holes 11 in the peripheral wall of the tubular body 4 as shown in FIG. Can be set.

Further, as shown in FIGS. 2 and 3, a through hole 12 through which the fastener 5 is inserted can be provided at an appropriate position on the peripheral wall of the tubular body 4. Of course, it is also possible to combine a plurality of the above-mentioned modified examples. A tubular body 4 which is fitted onto the small-diameter shaft portion 3 of the center rod 1 and fixed by a fastener 5.
The outer peripheral surface of does not have to be flush with the outer peripheral surface of the center rod 1. For example, as shown in FIG. 6, the outer diameter of the small-diameter shaft portion 3 is set so that the outer diameter of the tubular body 4 is smaller than the outer diameter of the intermediate rod 1, and the small-diameter shaft portion 3 is formed at the end portion thereof. The end face 6a of the hand 6 may be brought into contact with the stepped surface 13 formed to regulate the insertion depth of the small diameter shaft portion 3 into the middle rod insertion hole 7 of the hand 6. In this case, the outer peripheral surface of the center rod 1 and the outer peripheral surface of the hand 6 may be flush with each other.

[0010]

As described above, according to the Western umbrella of the present invention, the plastic cylindrical body interposed in the fitting portion between the wooden rod and the plastic hand is different from the wooden rod made of different materials. Since it is firmly and mechanically firmly fixed with fasteners such as nails, it can be firmly and easily and easily adhered to the plastic material of the same material with an adhesive or solvent for plastic. The mounting strength of the plastic hand on the wooden center rod can be greatly increased compared to the case where both are directly bonded with an adhesive. Therefore, even in a slightly rough use condition, there is almost no inconvenience that the plastic hand is accidentally dropped from the wooden center rod as in the conventional case. Moreover, in appearance, there is no difference from the case where the plastic hand is directly bonded to the wooden center rod, and there is no restriction on the design formation on the outer peripheral surface of the hand, so there is no fear of lowering the design value.
