[Solution] The folding umbrella of the present invention is a folding umbrella in which the leading rib that constitutes the ribs can be folded upward, and a tip engaging portion is provided on the upper surface of the umbrella cloth to engage the tip of the folded leading rib and change the umbrella width dimension in the direction perpendicular to the direction of travel.

Description

[Technical field]

[0001] The present invention relates to a folding umbrella that can be used upright on a bicycle or in areas with high foot traffic. [Background technology]

[0002] As shown in Figure 1, the width W of a conventional folding umbrella between tip 3d and tip 6d is 96 cm, which is the same length as the span DW. In other words, the width of a bicycle equipped with a folding umbrella is 96 cm. This was 36cm over the maximum bicycle width of 60cm set by the Road Traffic Act, and there was a problem in that if it was ridden on a public road, it would be a violation of the law and subject to criminal punishment.

[0003] In order to solve the above problems, Patent Document 1 proposes an anti-extension device, an umbrella equipped with an anti-extension device, and a method of using this umbrella. The anti-extension device pulls down the middle position of the ribs to narrow the width of the umbrella. However, there are problems in that the umbrella width becomes wider than the attachment position of the anti-extension device and the ribs are constantly under stress, which may cause deformation or damage.

[0009] The folding umbrella of the present invention will be described below with reference to Figs. The basic structure of the six-rib three-stage folding umbrella of the present invention, as shown in FIG. 1, consists of a regular hexagonal umbrella cloth (10) of the same size and six folding ribs (1-6). The ribs (1-6) consist of base ribs (1a-6a), tip dowels (1b-6b), tip ribs (1c-6c), tips (1d-6d), support ribs (1y-6y), and auxiliary ribs (1z-6z).

[0010] The length of the rib (HW) is 55 cm, and the width (W) of the umbrella is 96 cm across (DW). In order to fix the tips (1d-6d) of the foldable ribs (1-6) to the surface of the umbrella cloth (10), a pair of tip locking portions (1g-6g) and tip locked portions (1f-6f) are arranged on the surface of the umbrella cloth (10). The tip engaging portions (1g-6g) shown in FIG. 2 are provided on the surface of the umbrella cloth (10) near the connection between the main ribs (1a-6a) and the support ribs (1y-6y), and the tip engaged portions (1f-6f) are provided on the surface of the umbrella cloth 10 near the connection between the front ribs (1c-6c) and the tips (1d-6d). The tip engaging portions (1f to 6f) may be separate from the tips (1d to 6d), but in order to simplify the structure and improve usability, the tips (1d to 6d) are made to be the tip engaging portions (1f to 6f). The basic structure of the eight-rib two-stage folding umbrella of the present invention, as shown in FIG. 5, consists of a regular octagonal umbrella cloth (10) of the same size and eight folding ribs (1-8). The ribs (1-8) consist of base ribs (1a-8a), tip dowels (1b-8b), tip ribs (1c-8c), tips (1d-8d), support ribs (1y-8y), and auxiliary ribs (1z-8z).

[0011] The length of the rib (HW) is 55 cm, and the width (W) of the umbrella is 96 cm across (DW). The tip locking parts (20, 21) shown in FIG. 5 are provided independently on the upper surface of the umbrella cloth (10) between the ribs (5, 6) and between the ribs (1, 2). The tip locking portion (22) shown in FIG. 11 is provided in place of the tip locking portion (20) shown in FIG.

[0012] The tip locking portions shown in the figures are the tip locking portion (20) of the first embodiment shown in Figure 6, the tip locking portion (22) of the second embodiment shown in Figure 10, and the tip locking portion (23) of the third embodiment shown in Figure 13, but other shapes and structures may be used as long as they are capable of locking the tip.

[0013] The tip retaining portion (20, 21) of the first embodiment is made of synthetic resin material, and in the case of a two-stage folding umbrella with eight ribs as shown in Figure 5, it is independently located on the center line (M) of the straight line connecting the midpoint (1m) of the umbrella cloth edge (4h) and the midpoint (2m) of the umbrella cloth edge (1h). As shown in Figure 6, the tip locking portion (20) has the tip (7d, 4d), which is the tip lockable portion, inserted through openings (52, 53) formed on both sides, and the tip locking portion (21) has the tip (8d, 3d), which is the tip lockable portion, inserted through openings (50, 51) formed on both sides. In addition, in order to ensure ease of insertion without placing a load on the umbrella cloth (10), the tips of the tips (7d, 4d), (8d, 3d) in the tip engagement portion (20, 21) are not fixed but left with some play, so that they press against each other inside the tip engagement portion (20, 21), interfering with each other and preventing movement. If the tip retaining parts (20, 21) are made of synthetic resin, they can be fixed to the umbrella cloth (10) by gluing, welding or sewing, but if they are made of metal, they can be fixed with a magnet, and if they are made of synthetic resin or metal, it is desirable to cover them with cloth of the same material as the umbrella cloth (10) to prevent damage to the umbrella cloth.

[0014] The tip locking portion (22) of the second embodiment is formed by a gap (25) formed between the support plate (16) formed at the lower part of the ferrule (15) and the umbrella cloth (10) as shown in Figures 9 to 12. The tip engaging portion (22) may be made to face the support plate (16) and integrally formed with the support plate (16) using synthetic resin to form a tip engaging portion (26), or the support plate (16) and the tip engaging portion (26) may be provided with a recess for engaging the tip engaging portion (4d to 7d), thereby determining the position of the engaging portion of the tip (4d to 7d).

[0015] In the case of a three-stage folding umbrella with six ribs, as shown in FIG. 2, the tip locking parts (1g-6g) are provided near the connection between the base rib (1a-6a) and the tip rib (1c-6c) on the ribs (1-6), and the tip locked parts (1f-6f) are provided independently on the tips (1d-6d) of the ribs (1-6).

[0016] The tip retaining portion (23) of the third embodiment prevents rainwater from circulating and accumulating in the portion of the umbrella cloth (10) that is sandwiched together as shown in Figures 13 to 18. The tip retaining portion (23) is made of the same material as the umbrella cloth 10 and is sized to cover the tip (3d, 6d) and the umbrella cloth sides (2h and 3h), (5h and 6h). As shown in Figure 13, in the case of a three-section folding umbrella with six ribs, it is formed across the area between the tips (1d, 5d) and the vicinity of the tips (2d, 4d) of the folding umbrella, which are in the front-to-back direction of the direction of travel, and two of them are arranged parallel to the center line (M) of the umbrella. Figure 14 is an AA' cross-sectional view of the tip engaging portion (23), and Figure 15 is a BB' cross-sectional view of the tip engaging portion (23). The tip engaging portion (15) is sewn and bonded to the upper side of the umbrella cloth (10), and a gap (27) is provided between the tip engaging portion (23) and the umbrella cloth (10) on the opposite tip (3d) side. The gaps (27) in Figure 17 of the CC' cross section and Figure 18 of the AA' cross section are designed to accommodate the tip engaging parts, that is, the tips (1d, 5d) and (2d, 6d) and the umbrella cloth edges (2h, 3h) and (5h, 6h), and the tip engaging parts (23) are covered by the umbrella cloth (10), thereby preventing rainwater from entering.

[0017] Next, a first method for narrowing the umbrella width (W) of a three-stage folding umbrella will be described with reference to FIG. The ribs (3) are folded with the tip rib (3c) at the tip dowel (3b) and the umbrella cloth (10) sandwiched between the upper part of the original rib (3a), and the tip engaging part (3g) is engaged with the tip engaged part (3f). Similarly, the tip engaging part (6g) of the ribs (6) is engaged with the tip engaged part (6f), thereby narrowing the umbrella width W.

[0018] Furthermore, a method for transforming the two-stage folding umbrella of the present invention into a roughly rectangular or teardrop shape with an umbrella width W of 60 cm or less will be described with reference to Figs. The method for transforming the umbrella into an approximately rectangular shape involves folding the tip ribs (3c, 8c) of the umbrella (P) upwards at the tip dowels (3b, 8b) and engaging the tip with tip engagement portion 21 between ribs 1 and 2, and then folding the tip ribs (4c, 7c) upwards at the tip dowels (4b, 7b) and engaging the tip with tip engagement portion (20) between ribs (5, 6).

[0019] The length (L) of the umbrella (P) that has been deformed into an approximately rectangular shape is 90 cm, the shortest axis (SW) is 90 cm, and the width (W) is 55 cm. The length of each side (1h, 5h) is 37 cm. The shape of a conventional umbrella (P) is dome-shaped due to its lowered periphery, but when the two-stage folding umbrella of the present invention is deformed into an approximately rectangular shape, the repulsive force of the twisted tip ribs (1c, 2c) lifts the tip locking portion (21), and further, the repulsive force of the tip ribs (4c, 7c) lifts the tip locking portion (20), so that the entire umbrella (P) becomes horizontal.

[0020] Next, the method of transforming the umbrella into an approximately teardrop shape is to fold the tip ribs (4c to 7c) of the umbrella (P) in Figure 5, which has been transformed into an approximately rectangular shape, upwards at the tip dowels (4b to 7b), and engage the tip with the tip engagement portion (22) near the ferrule (15).

[0021] The length L of the roughly teardrop-shaped umbrella (P) is 80 cm and the width W is 55 cm. Also, when the umbrella is deformed into an approximately teardrop shape, the tip retaining portion (22) is lifted by the repulsive force of the twisted tip ribs (4c, 7c), and the entire umbrella (P) becomes horizontal. When the entire umbrella (P) is in a horizontal position, the blind spot in the upper part of the field of vision is reduced, improving compliance with the obligation to ride safely on a bicycle.

[0022] When the two-stage folding umbrella (P) of the present invention, which has been modified to be roughly rectangular or teardrop-shaped, is set up on the umbrella stand (26) of a bicycle (35), as shown in Figures 23 to 25, the umbrella (P) is fixed so that its center line (M) is parallel to the direction of travel of the bicycle, and the ferrule (15) is inserted through the hole (18) in the center of the rain cover (25) with a seat width (CW) of 60 cm or more to cover the upper part of the umbrella (P) from the front basket (31) to the rear basket (32).

[0023] Conventionally, when an umbrella (P) is opened, the periphery drops, but the umbrella (P) of the present invention, which has been deformed into an approximately rectangular shape, lifts the front tip engaging portion (21) upward with the repulsive force of the tip ribs (1c, 2c), and lifts the rear tip engaging portion (20) upward with the repulsive force of the tip ribs (1c, 2c), so that the entire roof (R) formed is horizontal, and the length (RL) of the roof is 90 cm. This ensures that the driver's (30) view to the upper front is not obstructed, and the space in front and behind the driver's (30) head is increased.

[0024] Next, the structure of the rib (3) of the three-stage folding umbrella in which the length of the base rib constituting the rib can be freely changed will be described with reference to Figs. 19 to 21. The lower wheel (13) that moves up and down the center rod (12) is made up of a 17 cm long support rib (3y), a 20 cm long main rib (3a), a tip dowel (3b), a 20 cm long main rib (3c), and a tip (3d). The support bone (3y) is connected at its midpoint to the auxiliary bone (3z) of the upper wheel (14) fixed to the center rod (12). The length (HW) of the main rib from the center line of the middle rod (12) to the tip of the tip (3d) is 55 cm.

[0025] Figure 20 shows the state in which the 20 cm long tip rib (3c) is folded over the 20 cm long base rib (3a) with the tip dowel (3b). As a result, the length of the rib (HW) from the center line of the middle rod (12) to the tip dowel (3b) is 35 cm.

[0026] Furthermore, in order to make the length of the rib (HW) 30 cm, the original rib (3a) which is 20 cm long is shortened to 15 cm as shown in Figure 21. The base ribs (1a to 6a) of the three-section folding umbrella consist of an inner tube (40) and an outer tube (41). The inner tube (40) is designed to pass through the outer tube (41). The length (HW) of the base rib can be adjusted by inserting the inner tube (40) into or removing it from the outer tube (41). In addition, the inner tube (40) and the outer tube (41) have an elliptical short axis cross section as shown in Figure 22, and the inner tube (40) and the outer tube (41) can be locked and unlocked by rotating relative to each other, and the length (HW) of the original rib can be adjusted and then fixed.

[0027] Figures 23 to 25 show an umbrella (P) of the present invention, which has been deformed into a roughly rectangular shape, set up in an umbrella stand (26) on a bicycle (35) so that its center line (M) is parallel to the direction of travel of the bicycle (35), and a rain cover (25) with a seat width (CW) of 60 cm or more is used to cover the front basket (31) to the rear basket (32) of the bicycle (35) with the ferrule (15) of the umbrella (P) passing through the hole (18) in the center. The part where the top of the umbrella (P) and the rain cover (25) overlap forms the roof (R). The size of the formed roof (R) is 90 cm in length (RL) and 60 cm in width (RW), complying with the 60 cm maximum width regulation for bicycles under the Road Traffic Act. In the enlarged view of the area around the tip of the dew (3b), the sheet of the rain cover (25) exceeds the tip of the dew (3b), hangs down and envelops the tip of the dew (3b). The tip of the dew (6b) is also enveloped by the rain cover (25), so the edge of the rain cover (25) fixes the edge of the erected umbrella (P), protecting the umbrella (P) from strong winds and gusts of wind and preventing accidents caused by the tip of the dew with nearby pedestrians.
