JP 2003-33211 A JP 2006-247149 A Japanese Patent No. 4119220 Utility Model Registration No. 3179352

  However, in the structure of the umbrella disclosed in Patent Documents 1 and 2, the rain protection piece (auxiliary fabric) (7) for preventing wetting is applied to the outer peripheral edge (6a) of the umbrella fabric (main fabric) (6). Because it is sold as a special umbrella in the attached state, it must be attached by sewing, bonding, welding, and other methods according to the material, so it can be attached according to the needs of the user, Or it cannot be used conveniently and removed.

  Moreover, the rain piece (auxiliary fabric) (7) attached to the outer peripheral edge (6a) of the umbrella fabric (main fabric) (6) is connected to the hook-and-loop fastener (15) (15) (8a) (8b). Even if they can be folded back to the inside of the umbrella cloth (main fabric) (6) by joining them together, the work is extremely troublesome, especially for children and the elderly, it is impossible to store them quickly and orderly. Is possible.

  Further, even in the configuration of the umbrella device disclosed in Patent Document 3, the pipe (4a) is fixed to the canopy (umbrella cloth) (3) or its strong bone (master bone) (2c), while being freely detachable. The pipe fitting rod (4a ') to be engaged needs to be fixed to the edge of the apron piece (5). Even if the apron piece (5) can be removed and carried, the umbrella body (2) itself Becomes special and expensive.

  In this regard, the rain leak prevention guard for umbrellas disclosed in Patent Document 4 has an advantage that a commercially available product can be used as the umbrella (u) itself, and the shielding sheet body (1) can be removed from the umbrella (u). However, the hook-like connection support portion (3) formed on the upper edge of the shielding sheet main body (1) is merely inserted and locked into the gap between the umbrella bone (p) and the umbrella cloth. Therefore, rainwater inevitably falls to the inside of the shielding sheet main body (1) from the seam generated between the peripheral edge (lower edge) of the umbrella cloth and the upper edge of the shielding sheet main body (1). Thus, the meaning of installing the shielding sheet main body (1) is lost.

  The present invention aims to improve such various problems, and in order to achieve the object, in claim 1, a membrane body having a substantially isosceles triangle shape that can partially overlap an unfolded umbrella cloth from the outside, and The membrane body comprises a substantially rectangular sagging membrane piece extending continuously and integrally extending from the bottom edge corresponding to the peripheral edge of the umbrella cloth in the membrane body,

  While forming a locking hole to the stone protrusion at the apex of the membrane body, a plurality of dew receiving slits are also distributed at the bottom of the membrane body,

  After the locking hole is locked to the top of the umbrella, by inserting and locking the tip receiving slit into the tip of the umbrella, the membrane body is overlapped with the umbrella fabric when used. It is characterized in that it is determined that the above-mentioned dripping film piece bends and hangs down from its peripheral edge.

  According to a second aspect of the present invention, the tip receiving slit of the membrane main body is cut out as a single long hole extending along the longitudinal direction of the main bone in the umbrella.

  In claim 3, the apex angle of the membrane body shaped in an isosceles triangle is set to about 135 degrees, and a total of four or a total of eight dew receiving slits are distributed at equal intervals along the bottom side of the membrane body. It is characterized by that.

  According to a fourth aspect of the present invention, the locking hole for the stone bump is formed as a locking ring made of an elastic material separate from the membrane main body, and is integrally attached to the apex of the membrane main body forming an isosceles triangle.

  Further, in claim 5, the membrane body and the hanging membrane piece from the bottom thereof are made of the same material as the cloth of the umbrella cloth,

  A fluorescent band that receives and reflects light at night is attached along the bottom of the sagging film piece.

  According to the above configuration of the first aspect, after the locking holes formed at the apex position of the film body in the wetting prevention film are detachably locked to the protrusion of the umbrella, the openings are distributed on the bottom side of the film body. The above-mentioned wetting prevention film is attached to the umbrella by a relatively simple operation of detachably inserting and locking a plurality of the tip receiving slits to the tip of the umbrella. It can be attached and used in a state where it hangs down properly, and if necessary, the wet protection film can be removed and the umbrella itself can be used alone as before, which is extremely convenient.

  Moreover, when the anti-wetting film is attached to the umbrella, the membrane body of approximately isosceles triangles overlaps the outer surface of the umbrella cloth, and the substantially rectangular dripping film piece that is continuously integrated with the film body is attached to the umbrella cloth. Since it bends and hangs down from its peripheral part and partially encloses the user's body, there is no seam between the umbrella and the inside of the enclosure of the wetting prevention film. There is no risk of rainwater falling.

  In that case, if the configuration of claim 2 is adopted, even if there is a difference in the length or thickness of the tip of the main bone in the umbrella, the tip receiving slit of the membrane body in the wetting prevention film is formed on the tip. It can be easily and securely inserted and locked, and is useful for adjustment during the insertion and locking operation.

  If the configuration of claim 3 is adopted, when the umbrella cloth is a rain umbrella divided into eight equal parts by a total of eight main bones, a total of 4 dew receiving slits distributed in the film body of the wetting prevention film are provided. If the umbrella cloth is a rain umbrella that is divided into 16 equal parts by a total of 16 main bones, the number of opening receiving slits distributed in the film body of the wetting prevention film is also 8 in total. In addition, by setting the apex angle of the membrane body, which is almost an isosceles triangle, to about 135 degrees, not only the user's body but also the carrying items such as infants, school bags, handbags, etc. It can be protected, and there is an effect that the user's field of view can be secured to the minimum necessary level.

  Further, if the structure of claim 4 is adopted, the locking ring formed at the apex position of the film body in the anti-wetting film is provided with its own elasticity even if the thickness of the umbrella's protrusion changes. Can be easily and reliably adhered to the stone tip, and there is no risk of the membrane body accidentally falling off the stone tip during use.

  Furthermore, if the structure of Claim 5 is employ | adopted, there exists an effect which can keep a user safe by the fluorescent band which receives and reflects the light from a passing vehicle etc. at night.

  In that case, the binding band (22) is made of the same material as the cloth of the umbrella cloth (14) and, as suggested in FIG. 5, is fixed to an appropriate portion of the umbrella cloth (14) by means such as sewing or welding. .

  Further, (23) is the above wetting prevention film for an umbrella, which is a transparent or translucent vinyl sheet, a colored or / and patterned synthetic fiber, cotton, canvas, or other umbrella cloth ( 14) It is made from the same material as the fabric of 14) and has a pentagonal outline shape reminiscent of an overall baseball home base.

  For example, if the umbrella cloth (14) is a transparent vinyl sheet, the wetting prevention film (23) is also a transparent vinyl sheet, and if the umbrella cloth (14) is a woven fabric with a color printed pattern, the wet cloth The prevention film (23) is preferably a woven fabric having the same pattern printed in color.

  That is, as shown in FIGS. 6 to 10, the anti-wetting film (23) has a substantially isosceles triangular film body (23 a) that partially overlaps the deployed umbrella cloth (14) from the outside. The membrane body (23a) is provided with a substantially rectangular drooping membrane piece (23b) extending continuously and integrally extending from the bottom (X1) corresponding to the peripheral edge of the umbrella cloth (14).

  The hypotenuse (Z) of the membrane body (23a) forming the above-mentioned isosceles triangle has substantially the same fixed length as the main frame (15) of the umbrella as shown in FIGS. It will extend almost in parallel. Similarly, a locking hole (24) is formed at the apex (P) of the membrane main body (23a) so as to be freely locked to and disengaged from the above-mentioned stone bump (11) of the umbrella. Further, a plurality of slits (25) for receiving the tips (16) of the main bone (15) are distributed at equal intervals on the bottom (X1) of the membrane body (23a).

  In this regard, in the umbrella of the illustrated embodiment, as is clear from FIGS. 1, 4, and 5, the umbrella cloth (14) is divided into eight equal parts by a total of eight main bones (15), and the wetting prevention film (23 ), The membrane body (23a) occupies at least three-eighth of the umbrella cloth (14). The apex angle (θ) is approximately 135 degrees.

  In addition, the base (X1) corresponding to the peripheral edge of the umbrella cloth (14) in the membrane main body (23a) is attached to each of the four adjacent main bones (15) as shown in FIGS. Receiving slits (25) of the exposed tips (16), all four in total, are arranged at regular intervals as one adjustment slot that extends along the longitudinal direction (vertical direction) of the main bone (15). It is notched and is defined so that the tip (16) can be easily received.

  Furthermore, the membrane body (23a) and the sagging membrane piece (23b) of the wetting prevention membrane (23) extend along the longitudinal direction (vertical direction) of the main bone (15) as shown in FIGS. It is bent or joined in a state like a mountain range, and a dew of a certain length is only present at the intersection of the base (X1) of the membrane body (23a) and the tip (16) of the main bone (15) in each mountain range. The first receiving slit (25) is cut in a ridge shape.

  Then, as shown in FIG. 1 and FIGS. 6 to 8, a substantially rectangular dripping film piece (23 b) is continuously and integrally formed from the bottom side (X 1) of the film main body (23 a). The vertical side (Y) of the sagging membrane piece (23b) protruding from the bottom side (X1) of the membrane body (23a) is the same as or longer than the length of the hypotenuse (Z) in the membrane body (23a). It is dimensioned to a short constant length, and it is easy to bind the hanging membrane piece (23b) from the outside to the polymerized state with respect to the membrane body (23a) which is overlapped with the umbrella cloth (14). It has been established.

  In that case, the locking hole (24) for a stone bump located at the apex (P) of the membrane body (23a) is made of an elastic material separate from the membrane body (23a) as shown in FIGS. It is preferable to embody as a retaining ring, and to attach and integrate the retaining ring (24) to the apex (P) of the membrane body (23a) by means such as welding, adhesion, or sewing. Even if there is a change in the thickness of the stone bump (11), the locking ring (24) of the membrane body (23a) can be stably and stably locked to the bumper bump (11) at all times. is there.

  Further, a fluorescent band (26) that receives and reflects light from a passing vehicle (including a bicycle) at night as shown in FIG. It is desirable to attach and integrate them by means such as welding, bonding, and sewing. This is because it helps to ensure the safety of the user.

  The apex angle (θ) of the membrane body (23a) shaped into the isosceles triangle is preferably set to about 120 degrees to about 180 degrees. When the angle is smaller than about 120 degrees, the horizontal piece (film width) (X2) of the hanging film piece (23b) protruding from the bottom side (X1) of the film main body (23a) becomes narrow, and the user still has There is a risk that the body, its carrying bag, handbag, and other belongings may get wet. On the other hand, if the angle is greater than about 180 degrees, the user may be wrapped around the user's body or the user's field of view may become narrower, which may cause danger in walking during rain. In this respect, it is practically most preferable to set the angle to about 135 degrees as in the illustrated embodiment.

  In using the anti-wetting film (23), the locking ring (24) located at the apex (P) of the film body (23a) shaped in an isosceles triangle is provided with a deployed umbrella umbrella. After being detachably locked to (11), a plurality of (four in total in the figure) dew receiving slits (25) that are also distributed in the bottom (X1) of the membrane body (23a), Each is inserted and locked to the tip (16) of the main bone (15) located corresponding to the umbrella.

  Then, as shown in FIGS. 1 to 5 and FIG. 11, the film body (23a) of the wetting prevention film (23) overlaps the umbrella cloth (14) partially from the outside with an isosceles triangle. From the bottom (X1) corresponding to the peripheral edge of the umbrella cloth (14) in the membrane main body (23a), the substantially rectangular sagging membrane piece (23b) of the wetting prevention membrane (23) continues by itself. Will be bent and drooping.

  As a result, the body of the user having the umbrella handle (12), the carrying bag, the carrying bag, and the like are kept in a certain angular range (in the illustrated example) by the dripping film piece (23b) of the wetting prevention film (23). It is surrounded by only about 135 degrees) and can be protected from rainwater wetness.

  In this regard, FIG. 11 shows the anti-wetting film (23) in order to protect the belongings such as the back of the body and infants, school bags, rucksacks, etc. from the wet against wind and rain blowing from behind the user. Although the dripping film piece (23b) hangs behind the user in the umbrella, it shows the use condition against the wind and rain blown from the front (front) direction and the lateral (left and right) direction of the user. In the case of protecting items held such as infants and handbags from being wet, the sagging film piece (23b) of the wetting prevention film (23) will hang down to the front or side of the user. Just change the direction of the umbrella and use it by hand.

  When the umbrella is folded while the wet protection film (23) is attached to the umbrella, the dripping film piece (23b) of the wet protection film (23) corresponds to the peripheral edge of the umbrella cloth (14). The membrane body (23a) is folded from the bottom (X1) to the outside, and the membrane body (23a) is extended to cover the umbrella cloth (14). 22), as shown in FIG. 12, it is only necessary to stably bind the umbrella fabric (14) in a folded state.

  Further, the wetting prevention film (23) extracts the dew receiving slit (25) of the film main body (23a) from the dew (16) of the main bone (15) in the umbrella, and then engages the film main body (23a). The retaining ring (24) can be carried by removing it from the umbrella head (11), and it can be used alone.

  In the illustrated embodiment, a hand-opened (non-automatic deployable) umbrella has been described. However, if the lower repel (21) is pushed into the hollow interior of the center rod (10) and submerged, the lower roll (17) is automatically The present invention can also be applied to so-called jump-type umbrellas that are lifted up and deployed.

  Further, in the illustrated embodiment, the configuration of the umbrella having the umbrella cloth (14) divided into eight equal parts by the eight main bones (15) and the wetting prevention film (23) suitable for the umbrella has been described. The present invention can also be applied mutatis mutandis to a rain umbrella having an umbrella cloth (14) finely divided by the number of the main bones (15) such as 12, 16 or the like.

  In that case, even if the number of the main bones (15) increases, the apex angle (θ) of the membrane body (23a) in the wetting prevention membrane (23) applied mutatis mutandis is always about 120 degrees to about 180 degrees. It is preferable to set the angle to about 135 degrees.

  In any case, the anti-wetting film (23) does not make the umbrella itself special or expensive, and can be detachably attached to various commercially available umbrellas as needed. The parasol itself in the removed state can be used alone as before, which is extremely convenient.
