Description

Safety Umbrella {SAFE UMBRELLA}

The present invention relates to an umbrella that can be easily opened and closed.

In the middle rod of an umbrella, the upper potter's wheel, the lower potter's wheel, and the upper burnt piece and the lower burnt piece are normally provided. One end of the upper stalk is connected to the upper potter's wheel, and the middle part of the upper stalk and the upper end of the lower potter's wheel (end of the water side) are connected by the lower arm, and the umbrella can be opened and closed by sliding the lower potter's wheel along the middle rod of the umbrella. have. The upper tanji piece is installed to hold the umbrella open, and the lower tanji piece is fixed to the folded state. The upper and lower bombardment pieces normally protrude from the intermediate rod and are configured to immerse in the intermediate rod under pressure.

In the above umbrella, when the umbrella is in a folded state, the bottom carbon piece is held by a hole provided in the potter's wheel below. When unfolding the umbrella, press down the bottom of the finger to immerse it in the middle rod to release the locking state, and slide the lower potter's wheel along the middle rod to the water side. When sliding, the upper end of the lower pottery contacts the upper tangier piece protruding from the middle rod, but when the lower pottery slides further, the upper tangier piece is pressed by the lower potter's wheel and immersed in the middle rod. When the lower potter's wheel passes through the upper bombardment piece, the upper bombardment piece again protrudes from the middle rod, and the edge portion of the bottom (end of the handle side) of the lower potter's wheel is locked to the upper bombardment piece and fixed with the umbrella open. When folding the umbrella, press the upper finger piece with your finger to immerse it into the middle rod and release the lower rust lock by the upper finger piece. In the state where the umbrella is unfolded, the force that is going to move to the handle side is applied to the lower potter's wheel, so when the fixing is released, the lower potter's wheel slides to the handle's side. This lower potter's wheel is further lowered to the lower bombardment piece, and the pressure of the lower potter's wheel is immersed in the lower tank piece with an intermediate rod and passed over it. When the lower bombardment piece comes to the position of the hole portion provided in the lower potter's wheel, no pressure is applied, so that the lower bombardment piece protrudes again from the intermediate rod, and is locked to the hole and fixed in the folded state.

However, in such an umbrella, when opening an umbrella, it is necessary to slide the lower potter's wheel in the water direction while pressing the lower carbon piece, and when folding the umbrella, it is cumbersome to open and close the umbrella. There was a problem in that the finger tip was pinched between the hole of the lower and lower potter's wheels and between the middle rod or the upper burnt piece and the lower potter's wheel during the opening and closing operation. This problem was especially noticeable in children.

On the other hand, a lot of research has already been carried out to solve the risk of opening and closing of the umbrella, for example, there is a potter's wheel for mass production of Patent Document 1. In this lower potter's wheel, the button which is free to move in the direction orthogonal to the lower potter's wheel with respect to the lower potter's wheel is installed in contact with the upper and lower carbon finger pieces engaged with the engaging part in a state where a part is exposed to the outside of the lower potter's wheel. By this, the upper and lower finger pieces can be moved to the evacuation position in the support poles according to the movement of the button when the button is pressed by the user's finger in the direction orthogonal to the axial direction of the support, so that the finger does not directly touch the upper and lower finger pieces. It is possible to release the engagement state of the upper and lower coal pieces and the lower potter's wheel, and to move the lower potter's wheel up or down the shore.

Patent Document 1: Utility Model Registration No. 3082020

Although the design which can open and close an umbrella safely like a potter's wheel for mass production of patent document 1 continues to be studied until now, the safe umbrella which can carry out an opening / closing operation of an umbrella more easily is still desired. .

SUMMARY OF THE INVENTION In order to solve the above problems, an object of the present invention is to provide an umbrella capable of easily performing an opening / closing operation of an umbrella, particularly an umbrella folding operation, as an umbrella without a risk of pinching a finger when opening and closing an umbrella.

The object of the present invention is that one end of the upper meat is connected to the upper rust furnace fixed to the water side of the middle rod, and one end of the lower meat is connected to the middle portion of the upper meat, and the other end of the lower meat is connected to the lower rust furnace inserted into the middle rod Umbrella cloth is opened and closed by sliding the lower potter's wheel inserted in the middle rod in the axial direction of the middle rod,

In the umbrella which is fixed to each of the state which an umbrella was opened, the state where an umbrella was folded by the lower potter's wheel being attached to the upper or lower bombardment piece installed in the middle rod,

The lower potter's wheel has a protective canister fitted with a pull strap.

The upper and lower finger pieces are mountain-shaped plates projecting in a direction perpendicular to the axial direction of the middle rod, respectively. The water-side and handle sides of each finger are acutely angled with respect to the axial direction of the middle rod. Although the angle of the side of the handle side is smaller than the angle of the side of the water tail side in the upper tangerine piece, the angle of the side of the water side is formed smaller than the angle of the side of the handle side in the lower tangerine piece,

When folding the umbrella while the umbrella is open, the umbrella can be folded by sliding the lower potter's wheel in the direction of the handle by pulling the pull string toward the handle of the middle rod,

When the umbrella is opened in the folded state, the umbrella is pushed in the water direction of the middle rod to slide the potter's furnace down in the water direction to solve the umbrella.

Each side except for the side in contact with the middle rod of the upper and lower bombardment piece is formed to be a curved surface, and the sides of the water side of the upper tangy piece and the side of the handle side of the lower edge is formed in an inclined side in two stages.

EMBODIMENT OF THE INVENTION Hereinafter, although one Embodiment of this invention is described referring an accompanying drawing, the technical scope of this invention is not limited by this. 1 is an overall front view of an umbrella in an unfolded state according to the present invention. FIG. 2 is a front view of the lower potter's wheel and the protective container in the unfolded state of the umbrella shown in FIG. 1, FIG. 3 is an enlarged view of a front sectional view of the lower potter's wheel and the protective container in the unfolded state of the umbrella, and FIG. Right side view of the lower potter's wheel and the protective container in this folded state, FIG. 5 is an enlarged view of a front sectional view of the lower potter's wheel and the protective container in the folded state, and an enlarged view of the lower tangerine piece. It is a figure which illustrates the installation position of the.

The lower potter's wheel 1 has a cylindrical shape in which a hole 2 is provided on the side, and one end of the base 3 is connected to the upper portion (water side). The other end of the lower arm 3 is connected to the middle of the upper arm 4, and one end of the upper arm 4 is connected to the upper rust furnace 5. The lower potter's wheel 1 is inserted into the middle rod 6, and the umbrella can be opened and closed by sliding the lower potter's wheel 1 along the middle rod 6. As shown in FIG. The upper tangy piece (7) is in the umbrella open state, the lower tangy piece (8) is installed in order to fix the umbrella folded, the upper tanji piece (7) and the lower tanji piece (8) is usually It protrudes from the intermediate rod 6, and is comprised so that it may be immersed in the intermediate rod 6 under pressure.

As shown in FIGS. 2 and 3, in the state where the umbrella is opened, the upper carbon finger piece 7 protrudes from the middle rod 6, and the edge portion 9 provided at the end of the handle side of the lower potter's wheel is the upper carbon finger piece ( 7), the umbrella is fixed in the open state. The protective cylinder 10 is inserted into the lower potter's wheel 1 in a cylindrical shape, and covers the lower potter's wheel 1 from under the foot connecting portion 11, and the end portion 12 of the handle side of the protective bucket has an edge of the lower potter's wheel ( 9) It is on the handle side. Close to the edge part of the handle side of a protective cylinder expands outward from the main-body part 13. The bulging portion 14 covers a part of the upper fingering piece 7 in a state where the umbrella is opened, but its inner diameter is larger than that of the main body part 13 so as not to pressurize the upper fingering piece 7. . Therefore, as shown in FIG. 3, the upper finger piece 7 completely protrudes from the middle rod 6, engages the edge 9 of the lower potter's wheel, and stably fixes the umbrella in the open state.

The edge portion 9 on the handle side of the lower potter's wheel bulges outward from the main body portion 15 of the lower potter's wheel, and the diameter of the edge portion 9 is formed from the protruding portion 16 of the protective container over the outlet portion 14. Although smaller than the inner diameter of the reduced portion 17, the larger than the inner diameter of the main body 13 of the protective cylinder. In a state where the protective casing 10 is attached to the lower potter's wheel 1 in a state in which it is attached, the edge portion 9 is located in the hollow of the reduction portion 17. When the protective cylinder 10 is pulled toward the handle side, the edge 9 of the lower potter's wheel is caught by the end of the handle side of the main body of the protective cylinder, so that the force in the handle direction also acts on the lower potter's wheel. As described above, the protective casing is inserted under the lower leg connecting portion 11, but the inner diameter of the end portion 18 on the water side of the protective tub is smaller than the diameter of the lower connecting portion 11. For this reason, when the protection cylinder 10 is pressed in the water direction, since the end part 18 contacts the base connecting part 11 and presses the connection part 11, the force in the water direction also acts on the potter's wheel 1 below.

The bulging portion 14 of the protective cylinder has a protrusion 19 formed integrally with the bulging portion 14 on a part of its outer circumference, and the protrusion 19 is provided with a through hole 20 in the axial direction of the intermediate rod. . The pulling string 21 is attached to the protruding portion 19 through the through hole 20. The pulling string 21 is composed of a thread string 22 tied to the protrusion and a ring-shaped synthetic resin string 23 fixed to the thread string 22. When folding the umbrella in the unfolded state of the umbrella, the pull string 21 is held, or a finger is caught on the ring shape of the synthetic resin string 23, and the pull string 21 is pulled toward the handle 24 side. When pulling out the pulling string 21, the protective container 10 is pulled to the handle side, and the lower potter's wheel 1 is also pulled to the handle side. The upper tungsten piece 7 is a mountain-shaped plate projecting in a direction perpendicular to the axial direction of the middle rod, and each side except the side in contact with the middle rod has a curved surface. It consists of the inclined sides a and b. The side a is formed at a slightly acute angle than the right angle with respect to the axial direction of the intermediate rod, and the side b is the side of the inclined slope from the upper end a 'of the side a to the vertex A of the finger piece. The side c is an uphill inclination over the vertex A of the finger piece on the handle side, and the angle θ _{2 with} respect to the axial direction of the middle rod of (c) is smaller than the angle θ ₁ of the side a. As the lower potter's wheel 1 is pulled toward the handle side, a force in the handle direction acts on the side a of the upper finger piece. Since the side a is slightly inclined toward the handle side rather than the right angle, the upper finger piece 7 is immersed in the intermediate rod 6 by pressing the side a in the handle direction. In addition, since the mechanism of a finger-tip piece can use the same thing as the mechanism of a finger-tip piece used for a general umbrella, it abbreviate | omits in sectional drawing shown in FIG. 3 and FIG.

In the unfolded state of the umbrella, the force that is trying to move in the direction of the handle acts on the lower rust furnace 1, and the side (b) of the upper tangy piece is located at the apex of the tangy piece at the top (a ') of the side (a). The height h ₁ from the outer periphery of the intermediate rod 6 to (a ') is the height from the outer periphery of the intermediate rod 6 to the inner wall of the lower potter's wheel, since it is comprised by the side of the gentle uphill inclination. If the upper finger piece 7 is immersed in the middle rod 6 until it is shorter than (h ₂ ), the lower potter's wheel 1 is the side (b) even if the pulling string 21 is not pulled in the handle direction. Slide in the direction of the handle while immersing the intermediate rod (6). While the lower potter's wheel 1 passes over the vertex A of the upper carbon bearing piece, the upper carbon bearing piece 7 is most immersed into the middle rod. When the lower potter's wheel 1 completely passes over the upper carbon piece 7, the pressure on the upper carbon piece 7 disappears, so that the upper carbon piece 7 again completely protrudes from the middle rod 6.

As described above, since the force to move in the handle direction acts on the lower potter's wheel 1, when the locking state by the upper finger piece 7 is released, it slides to the handle direction as it is, but the intermediate rod 6 The movement in the handle direction is stopped by the lower finger piece 8 protruding from the. In order to fix the umbrella in the folded state, it is necessary to engage the lower carbon piece 8 in the hole 2 of the potter's wheel down (Figs. 4 and 5, in the state where the umbrella is fixed in the folded state). ), The pull string 21 is further pulled in the direction of the handle to move the lower rust furnace 1 through the protective container 10 to the handle side.

Like the upper finger piece 7, the lower finger piece 8 is a mountain-shaped plate projecting in a direction perpendicular to the axial direction of the middle rod, and each side except the side in contact with the middle rod 6 is curved. have. The angle (θ ' ₂ ) of the side (d) of the water side with respect to the axial direction of the intermediate rod is smaller than the angle (θ' ₁ ) of the side (e) of the handle side, and the side (d) is the apex of the lower tangy piece from the water side. It is an uphill slope over (B). When the lower potter's wheel 1 is pulled toward the handle side, a force in the handle direction acts on the side d of the lower magazine piece, and the lower magazine piece 8 is immersed in the intermediate rod 6. The lower potter's wheel 1 slides in the direction of the handle while immersing the side d into the middle rod 6, and passes through the vertex B as it is. When the lower tungsten piece 8 comes to the position of the hole 2 provided in the lower potter's wheel 1, since no pressure is applied, the lower tungsten piece 8 protrudes again from the middle rod 6, and this hole Locked in the part 2, the umbrella is fixed in a folded state. The protective tube 10 is attached to the lower potter's wheel 1, but the inner diameter of the main portion 26 provided on the water tank side of the protective cylinder is larger than the inner diameter of the main body portion 13, and the bottom of the burnt piece in the folded state of the umbrella It is formed so that (8) is not pressed. Therefore, the lower tether piece 8 protrudes completely from the intermediate rod 6, is latched by the hole 2 of the lower rust furnace, and is fixed stably in the folded state.

When the umbrella is opened while the umbrella is folded, hold the protective container 10 and press it in the direction of water taste. When the protective container is pushed in the water direction, the force in the water direction also acts on the potter's wheel 1 below. The side of the handle side of the lower edge piece is composed of the edge (e · f) inclined in two stages as in the side (a · b) of the upper edge piece. (e) is formed at a slightly acute angle than the right angle with respect to the axial direction of the intermediate rod, the side (f) is the side of the ascending slope from the top (e ') of the side (e) over the vertex (B) of the tangerine piece. When the lower potter's wheel 1 is pressurized toward the water tank side, the force in the water tank direction acts on the side e of the lower carbon piece 8. Since the edge e is slightly inclined toward the water side rather than at a right angle, the lower finger piece 8 is immersed in the intermediate rod 6 by being subjected to a force in the water direction. The lower potter's wheel 1 is slid in the water direction, so that the height h ₃ to the outer circumference e 'of the middle rod 6 is the height h ₂ from the outer circumference of the middle rod 6 to the inner wall of the lower potter's wheel. If it becomes shorter than), since the force in the water direction acts on the side f this time, the side f is immersed in the intermediate rod 6.

When the lower potter's wheel (1) is pushed further in the water direction, the lower potter's wheel (1) passes directly above the vertex of the lower carbon piece. While the lower potter's wheel 1 passes over the vertex B of the lower ballistic piece, the lower piece of gold piece 8 is most immersed into the intermediate rod 6. When the lower potter's wheel 1 completely passes over the lower bombardment piece 8, the pressure on the lower bombardment piece 8 disappears, so that the lower bundle piece 8 again completely protrudes from the middle rod 6.

After the locking of the lower rust furnace 1 by the lower tungsten piece 8 is released, only a very small force acts until the upper tungsten piece 7 comes into contact with the protective barrel 10. When the edge part of the water side of the lower pottery contact | connects the upper carbon finger piece 7, the protective cylinder 10 is pressed with a strong force in the water direction. The side (c) of the handle side of the upper finger piece 7 is the side of the ascending slope from the handle side over the vertex of the upper finger piece as described above. When the lower potter's wheel 1 is pressed toward the water tank side, the force in the water tank direction acts on the side c of the upper carbon finger piece, and the upper carbon finger piece 7 is immersed in the intermediate rod 6. The lower potter's wheel 1 slides in the water direction while immersing the side c into the middle rod 6, and passes through the vertex as it is. When the lower potter's wheel 1 completely passes over the upper bombardment piece 7, the pressure by the lower potter's wheel 1 is released, so that the upper bombardment piece 7 protrudes again from the middle rod 6, and The edge portion 9 of the handle side of the potter's wheel is locked to the upper finger piece 7 so that the umbrella is fixed in an open state.

As described above, in the umbrella of the present invention, when the umbrella is folded in the unfolded state, the umbrella is opened in the folded state by pulling the pull string 21 mounted on the protective container 10 in the handle direction. In this case, the umbrella can be opened and closed by pressing the protective container 10 in the water direction. Since it is not necessary to press the finger piece directly with a finger, between the lower finger piece 8 and the hole 2 of the lower rust furnace, and between the middle rod 6 or the upper finger piece 7 and the lower rust furnace 1 The risk of fingertips disappearing and the umbrella can be opened and closed easily. Especially when folding an umbrella, since it is possible only by pulling the pulling string 21 to a handle direction, it is easy to handle even a child.

Although wood, synthetic resin, etc. can be considered as a material of the protective cylinder of this invention, since it is easy to process and adhere to the said shape, a synthetic resin is especially preferable. In addition, any method can be used as long as it is a method of combining the potter's wheel and the protective container so that it does not easily fall out when the umbrella is opened and closed. The protective casing should be shaped so as not to immerse the tungsten piece which holds the rust furnace into the middle rod in the state where the umbrella is unfolded and the umbrella is folded, for example, to enlarge the inner diameter of both ends of the protective casing. In a state where the umbrella is folded, a configuration may be adopted so as not to press the piece of fingertip.

The pull string of the present invention is preferably a sturdy one that is not easily broken, and the material, thickness and the like are not particularly limited as long as it has such a property. For example, a thread such as a lily yarn, a string made of plastic, or the like can be used. Moreover, it can also be comprised combining them. If it is formed in a ring shape, the umbrella can be folded more simply because the finger can be pulled out and pulled out. Mounting method for the protective pail of the pull strap can be any method if the configuration does not easily fall out. As shown in the embodiment, in addition to forming the protrusions 19 having the through holes 20 integrally formed in the protection cylinder, for example, through holes are formed in the protrusions 16 of the protection cylinder as shown in FIG. 6B, It can be mounted by passing the pull string through the hole. Alternatively, as shown in FIG. 6C, a crosslinking portion is formed between the bulging portion 14 and the protruding portion 16 to attach a pulling string, or as shown in FIG. 6A, a hole is made by forming a hole in the crosslinking portion, and the tie string is passed through. A structure for attaching the pull string can be added, and the pull string can be attached thereto. A name plate 27 or the like may be attached to the pulling string.

The tungsten piece of the present invention is a mountain-shaped plate protruding in a direction perpendicular to the axial direction of the middle rod, wherein the angle (θ ₁ ) of the water side of the upper tangerine piece and the angle (θ ′ ₁ ) of the side of the handle of the lower tange piece are Under pressure from the lower potter's wheel, the bombardment piece is immersed in the middle rod, and when the umbrella is opened and the umbrella is folded, the hole and the edge of the lower potter's wheel must be securely held. It needs to be formed slightly smaller. Specifically, about 70 degrees to about 85 degrees are preferable, and about 75 degrees to about 80 degrees are more preferable. In the case where the side of the water side of the upper side of the tangerine piece and the side of the handle side of the bottom side of the edge piece are configured as inclined sides in two stages, the angle (θ ₃ ) and the side of the side (a) and side (b) as shown in the figure. The angle θ ' ₃ between (e) and the side f is preferably about 125 degrees to about 145 degrees, and more preferably about 130 degrees to about 140 degrees. The angle (θ ₂ ) of the side of the handle side of the upper tangerine piece and the angle (θ ′ ₂ ) of the water tail side of the lower tangerine piece can be the same angle as those of the conventional umbrella. The range is desirable. In addition, it is preferable that each side except for the side in contact with the middle rod of the upper and lower finger piece is formed to be a curved surface.

Umbrella according to the invention has a lower potter's wheel, and a protective cylinder inserted into the lower potter's wheel, and is equipped with a pull strap to the protective cylinder, and further, the upper and lower magazine pieces, respectively, perpendicular to the axial direction of the middle rod The side of the water-side and the handle-side of each tungsten piece are acutely angled with respect to the axial direction of the middle rod, but the angle of the side of the handle-side is above the water-tight side. It is smaller than the angle of the side, and in the lower tangerine piece, the angle of the side of the water side is formed to be smaller than the angle of the side of the handle side, so that when the umbrella is folded from the expanded state, the pulling string is pulled toward the handle of the middle rod. I can fold an umbrella by a thing, and when I open an umbrella from an umbrella folded state, I push a protection container in the water direction of the middle rod It may be expanded by an. This makes it possible to easily open and close the umbrella, in particular, to operate the umbrella when folding, and at the same time, when the umbrella is opened and closed, the finger does not directly touch the finger of the finger, thereby preventing the risk of injuring the finger.

Shapes of the upper and lower bombardment pieces installed on the middle rod of the umbrella according to the present invention are formed so that each side except for the side in contact with the middle rod of the upper and lower bombardment pieces is curved, and the water side of the upper By forming the side and the side of the handle side of the lower tanji piece inclined in two stages, the opening and closing of the umbrella can be performed more smoothly.
