Description

  The present invention relates to umbrellas such as rain umbrellas and parasols.

  In recent years, low-priced umbrellas using vinyl chloride as a fabric have been sold at convenience stores and the like, aiming for use when it suddenly starts to rain. High-fashioned umbrellas that are more expensive but use polyethylene as a fabric are also widely used.

A vinyl chloride or polyethylene fabric is manufactured by joining substantially isosceles triangular fabric parts to each other by high-frequency thermal bonding utilizing the characteristics of these materials.
However, joining of fabric parts by high-frequency thermal bonding tends to cause variations in the strength of the joint portion when the management of temperature and bonding time during high-frequency heating is insufficient. In particular, jump umbrellas using fabrics bonded in this way (also called “one-touch umbrellas”, umbrellas that are opened by the force of springs by pushing the lower repels) are the joints of the fabric due to the impact of the bones when they are opened. Peeled off and caused a leak.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide an umbrella that is resistant to impact and is difficult to tear.

In order to achieve the above object, the following technical means were taken in the present invention.
That is, the umbrella according to the present invention is an umbrella provided with a fabric obtained by joining a plurality of substantially isosceles triangular fabric parts made of a resin sheet or film, and the fabric is adjacent to the fabric parts, The vicinity of the equal edge is bent in the same direction along the equal side, and the edge is sandwiched inside the tape folded so that the crease is in the longitudinal direction, and is sewn together with the tape. .

“Equilateral” here refers to two equal sides in an isosceles triangle.
According to the present invention, it is possible to provide an umbrella in which the fabric is resistant to impact and is difficult to tear.
Preferably, the tape is folded inward so that the folds are in the longitudinal direction within a range in which both edges extending in the longitudinal direction do not reach the crease, and are sewn to the fabric parts.
By doing in this way, fraying of a tape can be prevented.

The base edge of the fabric part may be sewn together with the tape while sandwiched between two folded tapes so that the crease is in the longitudinal direction.
The cloth may be formed of a transparent cloth part or a cloth part having a transparent part and a pattern part.
By providing a transparent part on the fabric of the umbrella, visibility during walking can be secured and fashionability can be enhanced.

  According to the present invention, it is possible to provide a fabric that is strong against impact and is not easily torn and an umbrella that is highly resistant to rain leakage and has excellent durability.

1 is a perspective view of an umbrella 1 according to the present invention, FIG. 2 is a plan view of the umbrella 1, FIG. 3 is a cross-sectional view taken along line AA in FIG. 2, and FIG. 4 is a perspective view of FIG.
In FIG. 1 and FIG. 2, the umbrella 1 includes a skeleton 2 and a fabric 3.
The skeleton part 2 is a center rod 4, a center rod 4 that can slide on the outer periphery of the center rod 4, and a slider that can slide on the outer periphery of the center rod 4. A coil spring 7 that is provided between the lower outer peripheral surface of the lower ring 6 and the intermediate cross 5 and the inner peripheral surface of the lower cross 6 that can be accommodated and urges in a direction to separate the intermediate cross 5 and the lower cross 6, and has one end Eight bones 8,..., 8 connected to the middle rod 4 so as to be rotatable, one end is pivotally connected in the middle of the bones 8,. 8 suspended bones 9, 9, one end of which is pivotally connected in the middle of the bones 9,... 9, and the other end of which is pivotally connected to the lower cross 6. 10,... 10, a stone bump 11 attached to the tip of the middle bar 4, a hand 12 attached to the other end of the middle bar 4, and an umbrella for keeping the umbrella closed And the like repelling 13.

When the umbrella 1 is not in use, the lower collar 6 is closed by engaging and locking a claw 14 integrated with the lower repellent 13 into a locking hole (not shown). When the locking by 14 is released, the coil spring 7 expands and is a so-called jump umbrella configured to push up and open the receiving bones 9... 9 and the hanging bones 10.
As shown in FIG. 2, the fabric 2 is formed by arranging eight isosceles triangular eight fabric parts 15,..., 15 so that the base forms the sides of a substantially regular octagon with the apex as the center. These are formed by joining adjacent equal sides.

The dough parts 15, ..., 15 for producing the dough 2 are joined as follows.
Referring to FIGS. 2 to 4, first, a portion of several millimeters from the edge of the equal sides of the fabric parts 15,..., 15 is folded in the same direction, and the folded portions 16, 16 of the adjacent fabric parts are faced to each other. Next, the tape 17 having a length substantially equal to the equal side is folded in two so that the fold is in the longitudinal direction, and the folds are in the longitudinal direction within a range where both edges extending in the longitudinal direction do not reach the folded fold. Fold each inside. The folded parts 16, 16 of the fabric parts 15, 15 are sandwiched inside the tape 17 folded in this way, and these are sewn together with a thread 18 to produce the fabric 2. That is, the fabric 2 is manufactured by piping with the tape 17 and sewing the polyethylene fabric parts 15,.

By manufacturing the fabric 2 in this way, it is more resistant to impact and tearing than the fabric manufactured by conventional high-frequency thermal bonding, thus preventing rain leakage, and umbrellas using polyethylene (POE) or vinyl chloride are broken. The image that it is easy can be wiped out.
The dough parts 15,..., 15 are made by cutting transparent sheet-like polyethylene into approximately isosceles triangles having a predetermined size. By making the fabric 2 transparent, it is possible to secure a field of view during walking. The fabric parts 15,..., 15 may be manufactured from other materials, for example, soft vinyl chloride or other synthetic resin sheets. A film made of a material having a high tensile strength can also be used. The dough parts 15,..., 15 may be made of colored sheets. A pattern or the like may be printed on the fabric 2. By printing a character or a brand mark, the added value of the umbrella 1 can be increased.

The tape 17 is made by cutting a bias cloth such as polyester, nylon, and cotton into a tape shape. Fabrics made of other materials such as vinylon, polyurethane and other synthetic fibers may be used.
The edge of the fabric 2 (corresponding to the edge of the bottom of the fabric part) is sandwiched between the tape 19 folded in half so that the crease is in the longitudinal direction, and is sewn together with the tape 19. For the tape, a fabric made of polyester, nylon, cotton fabric or other fibers, a sheet made of synthetic resin, or the like is used. By piping the edge of the fabric 2 with, for example, a tape woven with reflective fibers or with a reflective tape, the visibility from an automobile at night increases and the user can be protected from a traffic accident.

  In the above-described embodiment, the shape, material, joining method, and the like of the fabric can be appropriately changed in accordance with the spirit of the present invention.

  The present invention can be used for umbrellas such as rain umbrellas, parasols, and beach umbrellas.
