Description

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

  The middle pole of an umbrella is usually provided with an upper and lower cradle, and an upper and lower repellency. One end of the main bone is connected to the upper crossbone, and the middle part of the main bone and the upper end of the lower crossbone (end of the stone thrust side) are connected by the ribs, and the lower crosspiece slides along the middle rod of the umbrella By doing so, the umbrella can be opened and closed. The upper repellant is provided to fix the umbrella in the opened state, and the lower repellant is provided to fix the umbrella in the closed state. The upper and lower repellents normally protrude from the middle bar and are configured to be immersed in the middle bar when pressed.

  In the above umbrella, when the umbrella is in a closed state, the lower repellency is locked by a hole provided in the bottom pole. When opening the umbrella, hold the lower repellant with your finger to immerse it in the middle bar to release the locked state, and slide the lower wheel along the middle bar to the side of the stone. As you slide, the upper end of the bottom roller comes into contact with the upper repelling projecting from the center rod. However, when you slide the lower end still, the upper repel is held by the lower crossing rod and immerses in the middle rod. When the bottom crosses over the top repel, the top re-projects again from the center rod, and the bottom edge (end on the hand side) of the bottom cross is locked to the top repel and the umbrella is fixed open. The When closing the umbrella, press the upper repellant with your finger to immerse it in the middle bar, and release the anchor of the lower cradle by the upper repellant. In the opened state, the force to move to the hand side is applied to the handwheel, so if the lock is released, the handpiece slides to the hand side. The lower cradle is further pulled down to the lower repellency, and the lower repellency is immersed in the center rod by the pressure applied by the crumpler and passed over it. When the lower repellent comes to the position of the hole provided in the lower cross, the pressure is not applied, so the lower repel protrudes again from the center rod and is locked in the hole, and the umbrella is fixed in a closed state. The

  However, in such an umbrella, when opening the umbrella, it is necessary to slide the bottom wheel while pushing the lower repel, and when closing the umbrella, it is necessary to hold the upper repel, so it is troublesome to open and close the umbrella. In addition, there is a high risk of the fingertip being caught between the lower repellent and the hole of the lower peg and between the middle stick or the upper repellent and the lower peg during the opening / closing operation. This problem was particularly noticeable in children.

  On the other hand, the device for eliminating the danger of the opening / closing operation of the umbrella has already been made. In this lower part, the upper and lower buttons that are engaged with the engaging part in a state in which a part of the button that is movable in the direction perpendicular to the axial direction of the support column with respect to the lower part is exposed to the outside of the lower part. By providing it in contact with the repellant, it is possible to move the upper and lower repels to the retracted position in the support when the button is moved by the user's finger in a direction perpendicular to the axial direction of the support. In addition, it is possible to release the engagement between the upper and lower repels and the lower rokuro without directly touching the upper and lower repels so that the lower rokuro can be moved upward or downward.

  There has been devised so far that the umbrella can be opened and closed safely, such as the lower umbrella for Western umbrellas in Patent Document 1, but it is still safer to open and close the umbrella more easily. An umbrella was desired.

  In order to solve the above-mentioned problems, the present invention has an object to provide an umbrella that has no risk of pinching a finger when the umbrella is opened and closed, and that can be easily opened and closed, particularly an umbrella operation. To do.

The object of the present invention is that one end of a main bone is connected to an upper handle fixed to the stone thrust side of the middle rod, one end of a receiving bone is connected to an intermediate portion of the main bone, and the lower fitting is externally fitted to the middle rod. The other end of the rib is connected to the crossbone, and the umbrella cloth is opened and closed by sliding the bottom crosspiece fitted on the middle rod in the axial direction of the middle rod,
In the umbrella fixed to each of the open umbrella state and the closed umbrella state by locking the bottom rail to the upper or lower repellency provided in the middle bone,
A protective cylinder with a pull-down strap is fitted on the bottom of the bottom,
The upper and lower repellings are each a mountain-shaped plate that protrudes perpendicularly to the axial direction of the middle bar. However, the angle of the side on the hand side is smaller than the angle of the side of the stone thrust side in the upper repellent, and the angle of the side of the stone thrust side is smaller than the angle of the side of the hand side in the lower repellent. Formed small,
When closing the umbrella from the open state, by pulling the pull-down string toward the hand of the center rod, the lower rail can be slid in the hand direction to close the umbrella,
When opening the umbrella from the closed state, it is solved by an umbrella characterized by pressing the protective cylinder in the direction of the center stick and sliding the bottom rail in the direction of the target. The

  The upper repellent and lower repellent are formed so that each side excluding the side in contact with the middle bar of the upper repellent and lower repellent is a curved surface, and the side of the upper repellent side and the side of the lower repellent hand side However, it is also possible to form as a side inclined in two steps.

  The umbrella according to the present invention has a lower ring and a protective cylinder externally fitted to the lower ring, a pull-down string is attached to the protective cylinder, and the upper and lower repels are respectively attached to the axial direction of the middle bar. It is a mountain-shaped plate that protrudes in the vertical direction, and the side of the repelling side and the side of the hand side of each repellant form an acute angle with respect to the axial direction of the center rod. Close the umbrella from the open state by forming it so that the angle of the side of the stone is smaller than the angle of the side of the butt and the angle of the side of the butt is smaller than the angle of the side of the hand Sometimes, the umbrella can be closed by pulling the pull-down string in the direction of the middle rod, and when the umbrella is opened from the closed state, the umbrella can be opened by pushing the protective cylinder in the direction of pushing the middle rod. As a result, the opening / closing operation of the umbrella, in particular, the closing operation of the umbrella can be easily performed, and in the operation of opening / closing the umbrella, the finger does not touch the repel directly, and the risk of injury to the finger can be prevented. .

  The shape of the upper and lower repels provided on the middle rod of the umbrella according to the present invention is formed so that each side except the side in contact with the upper and lower repelled middle rods is a curved surface, and By forming the side of the stone thrust side and the side of the hand side of the lower repel as an inclined side in two stages, the umbrella can be opened and closed more smoothly.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the accompanying drawings, but the technical scope of the invention is not limited thereby. FIG. 1 is an overall front view of the umbrella according to the present invention in an opened state. FIG. 2 is a front view of the bottom pole and the protective cylinder in the opened state of the umbrella shown in FIG. 1, FIG. 3 is a front sectional view of the bottom pole and the protective cylinder in the opened state, and an enlarged view of the upper repellent, FIG. FIG. 5 is a cross-sectional view of the right side surface of the lower ring and the protective cylinder in the closed state and an enlarged view of the lower repelling, and FIG. 6 is an enlarged view of the umbrella according to the present invention. It is a figure which illustrates the attachment position of a drawstring.

  The bottom ladle 1 has a cylindrical shape, and has a configuration in which a hole 2 is provided on a side surface, and one end of a receiving bone 3 is connected to an upper portion (stone thrust side). The other end of the receiving bone 3 is connected to an intermediate portion of the parent bone 4, and one end of the parent bone 4 is connected to the upper crosspiece 5. The lower wheel 1 is fitted on the middle bar 6, and the umbrella can be opened and closed by sliding the lower wheel 1 along the middle bar 6. The upper repellant 7 is provided for fixing with the umbrella open and the lower repellant 8 is provided for fixing with the umbrella closed, and the upper repellant 7 and the lower repellant 8 are normally projected from the middle rod 6 and are not pressed. In such a case, the center rod 6 is configured to be immersed.

  As shown in FIG. 2 and FIG. 3, in the opened state, the upper repellent 7 protrudes from the middle bar 6, and the edge 9 provided at the end on the hand side of the lower cross is locked to the upper repellent 7. The umbrella is fixed in an open state. The protective cylinder 10 has a cylindrical shape, is fitted on the bottom skull 1, covers the bottom skull 1 from below the bone receiving connection part 11, and the end 12 on the proximal side of the protective cylinder is from the edge 9 of the bottom skull. , On the hand side. Near the proximal end of the protective cylinder bulges outward from the main body 13. The bulging portion 14 covers a part of the upper repellent 7 in the opened state, but its inner diameter is larger than the inner diameter of the main body 13 and is formed so as not to press the upper repellent 7. Therefore, as shown in FIG. 3, the upper repel 7 completely protrudes from the middle bar 6 and locks the edge 9 of the lower skull, thereby stably fixing the umbrella in an open state.

  The edge portion 9 on the hand side of the bottom roller bulges outward from the main body portion 15 of the bottom roller, and the diameter of the edge portion 9 is formed from the flange portion 16 to the bulging portion 14 of the protective cylinder. Although smaller than the inner diameter of the portion 17, it is larger than the inner diameter of the main body portion 13 of the protective cylinder. In a state where the protective cylinder 10 is fitted to the bottom pole 1, the edge portion 9 is located in the hollow of the constricted portion 17. When the protective cylinder 10 is pulled toward the hand side, the edge portion 9 of the bottom arm is hooked at the hand side end of the main body portion of the protection tube, so that a force toward the hand is also applied to the bottom arm. In addition, as described above, the protective cylinder is externally fitted under the bone receiving connection part 11, but the inner diameter of the end 18 on the stone thrust side of the protective cylinder is smaller than the diameter of the bone receiving connection part 11. For this reason, if the protective cylinder 10 is pushed in the stoning direction, the end 18 hits the bone receiving connection portion 11 and pushes the linking portion 11.

The bulging portion 14 of the protective cylinder has a protruding portion 19 formed integrally with the bulging portion 14 on a part of the outer periphery, and the protruding portion 19 has a through hole 20 in the axial direction of the center rod. Is provided. A pull-down string 21 is attached to the projection 19 through the through hole 20. The pull-down string 21 includes a thread string 22 tied to the protruding portion and a ring-shaped synthetic resin string 23 fixed to the thread string 22. When closing the umbrella from the opened state, the pulling string 21 is grasped or the fingers are put on the loop of the synthetic resin string 23 and the pulling string 21 is pulled toward the hand 24. When the pulling string 21 is pulled, the protective cylinder 10 is pulled toward the hand side, and the lower skull 1 is also pulled toward the hand side. The upper repellant 7 is a mountain-shaped plate that protrudes in a direction perpendicular to the axial direction of the center rod, and each side except for the side in contact with the center rod is a curved surface. The side is composed of sides a and b inclined in two steps. The side a is formed at a slightly acute angle from the right angle with respect to the axial direction of the center rod, and the side b is an obliquely rising side from the upper end a ′ of the side a to the apex A of the repellency. The side c is a side that rises obliquely from the proximal side to the apex A of the repelling, and the angle θ _{2 with} respect to the axial direction of the center bar of the side c is smaller than the angle θ _{1 of the} side a. By pulling the bottom wheel 1 to the hand side, a hand-oriented force is applied to the side a of the upper repellency. Since the side a is slightly inclined toward the hand side from the right angle, the upper repel 7 is immersed in the middle rod 6 when the side a is pushed in the hand direction. Note that the repelling mechanism can be the same as the repelling mechanism used for general umbrellas, and is therefore omitted in the cross-sectional views shown in FIGS.

In the opened state, the force to move in the direction of the hand is applied to the bottom wheel 1, and the side b of the upper repellant is a gently sloping upward side from the upper end a 'of the side a to the apex of the repellency. Therefore, the upper repellent 7 is moved to the middle rod 6 until the height h ₁ from the outer circumference of the middle rod 6 to a ′ becomes shorter than the height h ₂ from the outer circumference of the middle rod 6 to the inner wall of the bottom wall. When immersing in, even if the pull-down string 21 is not pulled in the hand direction, the lower skull 1 slides in the hand direction while immersing the side b in the middle bar 6. While the bottom wheel 1 is passing over the top A of the upper repellent, the upper repellent 7 is most immersed in the middle bar. When the bottom roller 1 has passed over the upper repellent 7, there is no pressure on the upper repellent 7, and the upper repellent 7 protrudes completely from the middle bar 6 again.

  As described above, since the force to move in the hand direction is applied to the bottom wheel 1, if the locking state by the upper repellent 7 is released, it slides in the hand direction as it is. The movement in the direction of the hand is stopped by the lower repelling 8 protruding from 6. In order to fix the umbrella in the closed state, it is necessary to lock the lower repel 8 in the hole 2 of the bottom rack (FIGS. 4 and 5 are diagrams showing the state fixed in the closed state). As shown in the figure, the pulling string 21 is further pulled in the direction of the hand, and the bottom wheel 1 is moved to the hand side through the protective cylinder 10.

Similarly to the upper repellent 7, the lower repellent 8 is a mountain-shaped plate that protrudes in a direction perpendicular to the axial direction of the central rod, and each side excluding the side in contact with the central rod 6 is a curved surface. The angle θ ′ ₂ of the side d on the stone thrust side with respect to the axial direction of the center rod is smaller than the angle θ ′ ₁ of the side e on the hand side, and the side d rises diagonally from the stone thrust side to the apex B of the lower repellent. Yes. By pulling the lower wheel 1 toward the hand side, a force in the hand direction is applied to the side d of the lower repelling, and the lower repelling 8 is immersed in the middle rod 6. The bottom roller 1 slides in the hand direction while immersing the side d in the middle bar 6 and passes over the vertex B as it is. When the lower repellant 8 comes to the position of the hole 2 provided in the lower rod 1, the pressure is not applied, so that the lower repellant 8 protrudes again from the center rod 6 and is locked to the hole 2, and the umbrella is Fixed in the closed state. Although the protective cylinder 10 is fitted to the bottom pole 1, the inner diameter of the bowl portion 26 provided on the stone thrust side of the protective cylinder is larger than the inner diameter of the main body portion 13 so that the lower repel 8 is not pressed in the closed state. Is formed. Accordingly, the lower repellant 8 completely protrudes from the middle rod 6 and is locked in the hole 2 of the bottom rail, and the umbrella is stably fixed in a closed state.

When the umbrella is opened from the closed state, the protective cylinder 10 is grasped and pushed in the direction of the stone. If the protective cylinder is placed in the piercing direction, a force in the direction of the piercing direction is also applied to the lower cross 1. The side of the lower side of the repelling is composed of sides e and f that are inclined in two steps, like the sides a and b of the upper repelling. e is formed at a slight acute angle from the right angle with respect to the axial direction of the center rod, and the side f is an obliquely rising side from the upper end e ′ of the side e to the apex B of the repelling. By pushing the lower wheel 1 to the stone thrust side, a force in the direction of the stone thrust is applied to the side e of the lower repelling 8. Since the side e is slightly inclined toward the stone thrust side from the right angle, the lower repelling 8 is immersed in the middle rod 6 by receiving a force in the direction of the stone thrust. When the bottom wheel 1 is slid in the direction of the stone, the height h ₃ from the outer periphery of the center rod 6 to e ′ becomes shorter than the height h ₂ from the outer periphery of the center rod 6 to the inner wall of the bottom rail. Since a force in the direction of the butt is applied to the side f, the side f is immersed in the middle bar 6.

  If the lower wheel 1 is pushed further in the direction of the stone, the lower wheel 1 passes over the top of the lower repellency. While the bottom roller 1 passes over the apex B of the lower repelling, the lower repelling 8 is most immersed in the middle bar 6. When the bottom roller 1 has passed over the lower repellent 8, the lower repellent 8 is no longer pressed, and the lower repellent 8 protrudes completely from the middle bar 6 again.

  The protective cylinder 10 is slid in the direction of the stone thrust with a slight force until the lower repellent 8 is no longer locked by the lower repellent 8 and until it contacts the upper repellent 7. When the end of the lower pricking side touches the upper repellent 7, the protective cylinder 10 is pushed with a stronger force in the direction of the plowing. The side c on the hand side of the upper repellent 7 is a side that rises obliquely from the hand side to the apex of the upper repelling as described above. When the bottom roller 1 is pushed to the side of the stone thrust, a force in the direction of the stone thrust is applied to the side c of the upper repelling, and the upper repelling 7 is immersed in the middle rod 6. The bottom roller 1 slides in the direction of the butt while immersing the side c in the middle bar 6 and passes over the top as it is. When the bottom roller 1 completely passes over the upper repellent 7, the lower repellent 1 is not pressed, so that the upper repellent 7 protrudes again from the middle rod 6, and the edge 9 on the hand side of the lower cross rebounds 7, the umbrella is fixed in an open state.

  As described above, in the umbrella of the present invention, when the umbrella is closed from the open state, the pulling string 21 attached to the protective tube 10 is pulled in the hand direction, and when the umbrella is opened from the closed state, the protective tube 10 is opened. The umbrella can be opened and closed by pushing in the direction of the stone. Since there is no need to press the repel directly with fingers, there is no risk that the fingertip will be caught between the lower repel 8 and the hole 2 of the bottom and the middle rod 6 or the upper repel 7 and the bottom 1. In addition, the umbrella can be easily opened and closed. In particular, when the umbrella is closed, it is only necessary to pull the pulling cord 21 in the direction of the hand, so that even a child can easily handle it.

  The material of the protective cylinder of the present invention may be wood, synthetic resin, or the like, but synthetic resin is particularly preferable because it can be easily processed and attached to the shape. Further, the method of fitting the bottom wheel and the protective cylinder may be any method as long as it does not easily come off during the opening / closing operation of the umbrella. The protective cylinder only needs to have a shape that does not allow the repelling that holds the bottom rail in the opened state / closed state to be immersed in the middle rod, for example, by forming the inner diameter of both ends of the protective cylinder large, It is possible to take a configuration that does not press the repellency when the umbrella is in the opened state or the closed state.

  The pulling string of the present invention is preferably a strong one that is not easily cut, and the material, thickness, etc. are not particularly limited as long as it has such properties. For example, knitting yarn such as lilyan, plastic string, and the like can be mentioned, and these may be combined. If it is formed in a ring shape, it can be pulled with fingers, so the umbrella can be closed more easily. Any method may be used for attaching the pull-down strap to the protective cylinder as long as it does not easily come off. As shown in the embodiment, the protrusion 19 provided with the through hole 20 is used as the protective cylinder. In addition to being integrally formed, for example, as shown in FIG. 6B, a through hole may be provided in the flange portion 16 of the protective cylinder, and the pull-down string may be attached through the hole, or the bulging portion as shown in C Add a structure for attaching the pulling string, such as forming a bridging part between 14 and the collar part 16 and attaching the pulling string, or as shown in A, opening a hole in the bridging part and tying it through the pulling string, A pulling string may be attached to this. A name plate 27 or the like can be attached to the pulling strap.

The repellency of the present invention is a mountain-shaped plate that protrudes in a direction perpendicular to the axial direction of the center rod, and the angle θ _{1 of} the upper repelling side of the stone thrust side and the angle θ of the lower repelling side of the hand ' ₁ is because the repellant is immersed in the center rod under the pressure of the bottom roller and the hole and edge of the bottom rail must be stably locked in the opened and closed states. It needs to be formed slightly smaller than 90 degrees with respect to the axial direction of the bar. Specifically, about 70 to about 85 degrees is preferable, and about 75 to about 80 degrees is more preferable. When the side of the upper repelling side and the side of the lower repelling side are inclined as two steps, the angle θ ₃ and the side e of the side a and the side b as shown in FIG. The angle θ ′ ₃ between the side f 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 upper repellent side and the angle θ ′ ₂ of the lower repelled stone thrust side may be the same angle as that of a conventional umbrella repelling, specifically, a range of about 20 degrees to about 50 degrees. Is preferred. Moreover, it is preferable that each side except the side in contact with the middle bar of the upper and lower repellency is a curved surface.
