Description

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

[Conventional technology]

Western umbrellas that shorten the length of the umbrella ribs when folded include those in which a series of opening and closing ribs 3 are interposed between the handle shaft 1 and the tip rib 2, as shown in Figure 6, and those in which a series of opening and closing ribs 3 are interposed between the handle shaft 1 and the tip rib 2, as shown in Figure 7. As shown, there is a model in which two series of opening/closing bones 3 are interposed between the handle shaft 1 and the tip bone 2, and in both cases, as the elevating wheel 4 descends, the tip of the original bone 5 constituting the opening/closing bone 3 is inserted. While lowering it, pull the end of the tip bone 2 toward the fixed potter's wheel, and also pull the tip of the tip bone 5 and the tip bone 2.
A connecting bone 6 whose both ends are connected to the distal end of the front bone 2 is pushed out to rotate the tip bone 2 in the folding direction.

According to the above configuration, when the umbrella is opened, the connecting bones 6
A large gap is created between the connecting part of the main rib and the umbrella cloth 7, and the umbrella cloth cannot be fixed directly to the main rib, so a hanging string 8 is required, which makes the work troublesome and causes an increase in cost. There was a problem.

Therefore, as shown in Fig. 8 (some models use a series of opening and closing bones), a cylindrical sheet metal 9 is attached to the opening and closing bones 3.
At the same time, the connecting bone 6 is slidably passed through the inside of the sheet metal 9 to connect the tip of the original bone 5 and the end of the tip bone 2 with a substantially straight line, and the connecting bone 6 is attached to the tip of the original bone 5. The umbrella cloth 7 is directly tied with thread.

[Problem that the invention attempts to solve]

The connecting bone bends in an arc to fit into the groove closed by the sheet metal of the opening/closing bone, and the outer circumferential surface of the connecting bone is pressed against the edge of the sheet metal and rubbed as the connecting bone slides, so there is no metal generated due to wear. A problem arose in which the umbrella cloth became stained with powder, making it unsightly.

Furthermore, when the umbrella is closed, the tip bones cannot be folded to a position parallel to the handle axis due to the strong frictional resistance between the sheet metal and the connecting bones, so a problem arises in that the tip of the tip bones must be assembled with one hand.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention is constructed by providing a slider in a portion of the opening/closing bone parallel to the connecting bone, and engaging the connecting bone with the slider.

[Effect]

The slider slides together with the connecting bones as the umbrella opens and closes.

〔Example〕

In the figure, reference numeral 21 denotes an extensible handle shaft, and a fixed potter's wheel 22 and a handle 23 are provided at the upper and lower ends of this handle shaft 21.

Further, the handle shaft 21 is provided with an elevating wheel 25 that can be stopped at the upper end of the handle shaft 21 by means of a tongue piece 24, for example.

Furthermore, the fixed potter's wheel 22 and the elevating potter's wheel 25 are rotatably attached to the ends of a series or two series of opening/closing ribs 26.

As shown in FIG. 1, the above-mentioned opening/closing bone 26 includes a support bone 28 whose end is rotatably attached to the elevating wheel 25 via a pin 27, and a pin 29 attached to the middle of the support bone 28 and the fixed wheel 22. A series of base bones 30 are rotatably attached at both ends via a screw, and as shown in FIG.
A base bone 30 rotatably attached at both ends via pins 31, a swinging bone 33 rotatably connected at both ends via pins 32 to the middle of the base bone 30 and the elevating wheel 25; There is a two-row type that is constructed of a connecting rod 35 whose both ends are rotatably attached to the end of the swing bone 33 on the side of the base bone 30 and the end of the support bone 28 via a pin 34.

Further, the distal end of a tip bone 37 is rotatably attached to the tip of the support bone 28 via a pin 36.

Reference numeral 38 denotes a connecting bone in which both ends are rotatably connected to the distal end of the tip bone 37 and the tip of the original bone 30 via a pin 39.

A slider 40 is provided to slide in the axial direction on a portion of the support bone 28 parallel to the connecting bone 38, and the connecting bone 38 is engaged with the slider 40.

As shown in FIG.
There is a method in which a U-shaped bent portion 42 provided in the middle is passed through and engaged with the cylinder 41, and the cylinder 41 is slid together with the connecting bone 38, or as shown in FIG. A U-shaped bent plate 43 is fitted into the
A pin 4 is installed between both ends of the bending plate 43.
4, the annular portion 45 of the halfway cut end of the connecting bone 38 is rotatably attached, and the bending plate 43 is attached together with the connecting bone 38.
There are methods such as sliding the .

In addition, by using a steel wire or the like with excellent elasticity for the connecting bones 38 and bending the tips of the connecting bones 38 as shown in the figure, when the umbrella cloth is closed in an inverted state, the connecting bones 38 is easily bent into an arc shape, and a force is applied to the tip bone 37 to restore its inversion.

Therefore, even if the umbrella cloth is reversed, the umbrella can be closed and returned to its original state without having to undo the reverse of the umbrella cloth one by one.

〔effect〕

As described above, according to the folding umbrella according to this invention, a slider is provided in the part parallel to the connecting bone of the opening/closing bone, and the connecting bone is engaged with the slider, so that the umbrella can be opened or closed. At times, the slider slides together with the connecting bones.

Therefore, it is possible to eliminate the problem of staining the umbrella cloth due to the generation of metal powder due to abrasion caused by the sliding of the connecting bones pushed in by the sheet metal.

Furthermore, the tip bones can be folded so that the tip faces near the outer periphery of the handle shaft due to the smooth sliding of the connecting bones, so it is possible to eliminate the time-consuming work of assembling the tip portions one by one by hand.
