Description

[Detailed explanation of the idea] [Industrial application field] This invention relates to a folding Western umbrella.

[Conventional technology]

As shown in FIGS. 5 and 6, a Western umbrella with a shortened umbrella rib length when folded has an opening/closing rib 3 interposed between the handle shaft 1 and the tip rib 2 to prevent the lowering of the lifting wheel 4. At the same time, while lowering the tip of the base bone 5 constituting the opening/closing bone 3, the end of the base bone 2 is pulled toward the fixed wheel 6, and a wire rod with both ends fixed to the tip of the base bone 5 and the end of the base bone 2 is attached. The connecting bone 7 is pushed out and the tip bone 2 is rotated in the folding direction.

Further, the above-mentioned connecting bone 7 can be made to pass through the inside of a sheet metal 8 wrapped around and fixed to the opening/closing bone 3 as shown in FIG. The body 8' is fitted and passed through the inside of the cylindrical body 8', and a hooking portion 9 bent in the middle of the connecting bone 7 is engaged with the cylindrical body 8'.

It should be noted that the above-mentioned opening/closing ribs 3 have a series as shown in FIG. 6 in addition to the double series shown in FIG. 5.

[The problem that the idea aims to solve]

When the umbrella is closed, the connecting bones are pushed out and the tip bones are smoothly rotated in the folding direction.In order to pull the connecting bones toward the opening/closing bones in the middle, the connecting bones are wrapped and fixed with sheet metal, or connected to a sliding cylindrical body. Since the engaging portion of the bone is engaged, it is time-consuming and
There was a problem that caused a significant increase in costs.

In addition, in the case of a double-barreled opening/closing bone, the connection part 12 between the quadrilateral midrib 10 and the supporting bone 11 formed at the tip of the original bone is smoothly raised and lowered from just before it passes the dead point. There was a problem in that the lifting wheel had to be slid with strong force because of the added resistance that inhibited sliding.

Furthermore, since the tip bone tends to swing sideways, the end of the tip bone comes off from the tip of the opening/closing bone, causing the tip bone portion of the umbrella cloth to turn over.

As a result, there was a problem that the attachment part of the tip bone was easily damaged.

[Means to solve the problem]

In order to solve the above problems, this invention consists of a series or two series of opening and closing bones whose ends are rotatably attached to a fixed potter's wheel and an elevating potter's wheel with a telescoping shaft, and a distal end attached to one of the tips of the opening and closing bones. In a folding western umbrella, which is composed of a tip bone that is rotatably attached, and a connecting bone made of a wire rod whose both ends are rotatably attached to the other end of the opening/closing bone and the end of the tip bone, the wire rod of the connecting bone is It is folded, parallel lines intersect in an X-shape, and opening and closing bones are interposed between the parallel lines before and after the intersection.

[Effect]

As the umbrella opens, the X-shaped intersection of the connecting bones slides toward the ends of the opening and closing bones, and the ends of the end bones are pulled together so that the end bones open.

Further, as the umbrella is closed, the X-shaped intersection of the connecting bones is slid toward the distal end of the opening/closing bone, and the end of the tip bone is protruded to rotate the tip bone in the folding direction.

〔Example〕

In the figure, 31 is a telescopic handle shaft, and a fixed potter's wheel 32 is attached to the upper end of this telescopic handle shaft 31.
1 is provided with an elevating potter's wheel 34 that can be stopped at the upper end of the telescopic handle shaft 31 by means of a tongue piece 33, for example, as shown in the figure.

Furthermore, the fixed potter's wheel 32 and the elevating potter's wheel 34 include:
The ends of a series or two series of opening/closing bones 35 are rotatably attached.

As shown in FIGS. 1 to 3, the above opening/closing bone 35 consists of a base bone 36 whose end is rotatably attached to a fixed potter's wheel 32, and a pin 37 inserted midway through the base bone 36 to rotate the distal end. A supporting bone 38 which is movably attached and whose end is rotatably attached to the elevating potter's wheel 34, a swinging bone 40 whose end is rotatably attached to the tip of the base bone 36 via a pin 39, and a supporting bone 38. A double structure consisting of a connecting rod 42 whose both ends are rotatably connected to the tip of the swinging bone 40 and the end of the swinging bone 40 via a pin 41, or an elevating wheel 34 as shown in FIG. It consists of a base bone 36 whose end is rotatably attached, and a support bone 38 whose end is rotatably attached to a fixed potter's wheel 32 and whose tip is rotatably attached via a pin 37 in the middle of the base bone 36. There are a series of structures.

Further, the distal end of a tip bone 44 is rotatably attached to one tip of the opening/closing bone 35 via a pin 43.

One tip of the tip bone 44 is attached to the swinging bone 40 in the case of a double structure, and to the base bone 36 in the case of a continuous structure.

Reference numeral 45 denotes a connecting bone whose both ends are rotatably connected to the distal end of the tip bone 44 and the other distal end of the opening/closing bone 35.

The above-mentioned connecting bones 45 are made by bending a single wire in half, making the parallel lines intersect in an X shape, and interposing the opening/closing bones 35 between the front and rear parallel lines sandwiching the intersection.

The opening/closing bone 35 interposed between the parallel lines is the swinging bone 40 in the case of a double structure and the original bone 36 in the case of a continuous structure.
It is passed through.

The other end of the opening/closing bone 35 is attached to the connecting rod 42 in the case of a double structure, and to the support bone 38 in the case of a continuous structure. The bent portion of the wire is inserted into the ring 46 formed by pressing the wire outwardly by pressing, and the bent hook portions at both ends of the wire are inserted into the transparent holes at the distal end of the tip bone 44 to attach the wire.

As the connecting bone 45 having the above structure is opened, the X-shaped intersection portion slides in the opposite direction of the tip bone 44, draws the end of the tip bone 44, and opens the tip bone 44.

In addition, as the umbrella is closed, the X-shaped intersection of the connecting bones 45 is slid in the direction of the tip bone 44, and the tip bone 44
The end of the tip is pushed out, and the tip bone 44 is folded back.

〔effect〕

As described above, according to the folding umbrella according to this invention, the wire rods of the connecting ribs are bent in half and made parallel to each other, and the parallel lines are bent in an One tip of the opening/closing bone is interposed between the parallel lines, and both ends of the connecting bone are attached to the end of the tip bone and the other tip of the opening/closing bone. The labor-intensive process of penetrating the cylindrical body fitted into the bone becomes unnecessary.

In addition, as the umbrella opens and closes, the X-shaped intersection of the connecting bones slides against the opening and closing bones, and the opening and closing bones are embraced by the front and back parallel lines that sandwich the X-shaped intersection, which prevents lateral vibration of the tip bone. stop.

This prevents the end of the tip bone from coming off from the tip of the opening/closing bone, and prevents damage to the attachment portion of the tip bone due to inversion.

Furthermore, since the distance between the front and rear parallel lines sandwiching the X-shaped intersection of the connecting bones can be freely increased or decreased when the umbrella is opened or closed, the slide of the elevating potter's wheel does not become heavy due to resistance.
