Description

  The present invention relates to an umbrella that is not damaged by wind pressure during use.

  Recently, due to abnormal weather, a large amount of rainfall often occurs at a time, and in such a situation, since the atmospheric pressure arrangement changes rapidly, there is often a strong wind like a typhoon. And if you hold an umbrella in such a typhoon or strong wind, the umbrella cloth will be subjected to a large wind pressure, and the user may fall down due to the large wind pressure or the umbrella may fly and damage the body become. In addition, when a conventional umbrella receives wind pressure from the inside, it reverses in a so-called funnel shape, and when received from the outside, a situation occurs in which the umbrella is bent and deformed inward.

  In particular, there is a lot of demand for low-priced products recently, and the material of the main bone is not sufficient, and there are more cases where the main bone is easily bent and reversed when a strong wind blows. It is dangerous to injure the surrounding people by reversing greatly. Especially, if the main bone is made of metal, its cross section is bent into a U shape and maintains its strength. It is difficult to return to the original position, it will be disposed of, and there will also be economic problems such as the waste bin and the burden of the disposal place. And the connecting part of the accessory bone will be broken.

  In addition, umbrella cloth that receives wind pressure is fixed by the tip attached to the tip of the main bone, but in many conventional inexpensive umbrellas, the tip is simply inserted without sewing, and the tip is exposed when the umbrella cloth is reversed. As a result, the umbrella cloth is separated from the inverted main bone, so that a very dangerous situation is also assumed in which the sharp tip of the main bone is exposed.

  Therefore, for example, an umbrella provided with means for passing the wind hitting the umbrella cloth to the outside is presented in, for example, Japanese Patent Application Laid-Open No. 2010-124883, but means for passing the wind presented in these publications Umbrellas having a complicated structure are not applicable to umbrellas with a low price.

  Further, for example, Japanese Patent Application Laid-Open No. 2011-87887 discloses an umbrella in which a cut main bone is connected and the connecting portion is held in a straight line by a biasing force of a spring. The umbrella is kept open by the tension of the umbrella cloth stretched around the main bone, but this umbrella cushions the wind pressure by the urging force of the spring in strong winds, and if the coil spring is weak, the parent bone is connected. It cannot be maintained in a state, and if it is strong, there is a contradiction that it receives wind pressure more than necessary, which is not practical. In particular, when the spring is strong, the wind pressure exceeding the setting and the reaction thereof act on the umbrella, which may cause a very dangerous situation for the user.

  This is because in the conventional folding umbrella having a structure similar to the structure presented in the above publication, a stretching force exceeding the tension generated by the main bone and the umbrella cloth is applied to the connecting portion when opened. In this case, when a large wind pressure is applied, the stretching force is suddenly exceeded and the connecting portion is bent and damaged.

  In addition, in the folding umbrella, the parent bone is folded at at least one place at a predetermined position in order to fold, but the position is located in the distal direction from the connection position of the parent bone with the sub bone. Therefore, the effect of decompression is not sufficient, and damage to the connecting portion between the parent bone and the secondary bone cannot be avoided.

  On the other hand, if it is reversed by strong winds. For example, Japanese Utility Model Publication No. 6-132 and Utility Model Registration No. 3132596 disclose an umbrella having means for reversing the main bone to prevent damage to the main bone when there is a strong wind in advance.

  However, the umbrella that is reversed by the strong wind presented in this publication to prevent damage is reversed with the base end of the main bone as the base axis, and since the main bone is largely reversed at the time of reversal, the risk to the surroundings increases, In addition, it is impossible to solve the safety problem that a large reaction is transmitted to the hand and cannot be held and separated, and the flying umbrella hurts people around.

  In addition, the known umbrella that is inverted is effective when the wind blows from the inside, but cannot cope with the strong wind from the outside, and there is a problem that the parent bone is bent inward. .

  As for the conventional tip, for example, the one shown in Japanese Patent Laid-Open No. 9-326 is known. As shown in FIG. 19, the tip is made of, for example, a synthetic resin. A tip 601 with a rounded tip is attached, and a base end portion 62 is pivotally attached to the outer periphery of the upper scissors 3 disposed at the tip of the middle shaft 4 having the handle 1 at the base end, and is attached to be openable and closable. An umbrella cloth 8 is stretched around a plurality of master bones 6 and a tip 621 formed of an appropriate elastic material is formed on a tip portion 621 of a distal end portion 61 of the master bone 6 in a fitting insertion hole 612 formed in a base end portion 611 thereof. By inserting and fixing, the tip 621 of the main bone 6 prevents the body such as the hand and the face from being damaged, and the tip 601 in the conventional umbrella is formed at the base end 611 thereof. Insert the tip 621 of the main bone 6 into the inserted insertion hole 612 For example, when the umbrella cloth 8 is loosened, such as when the umbrella is folded or when a strong wind is received, there is a problem that the tip 601 is easily removed. However, there is a problem that not only productivity is inferior and productivity is increased but also material costs are increased, particularly when the main bone 6 is made of a synthetic resin. However, in the case of metal, the adhesive effect could not be sufficiently exhibited.

  Therefore, in the umbrella shown in Japanese Patent Application Laid-Open No. 2001-61524 shown in FIG. 20, an umbrella in which a synthetic resin dew 601 is fixed to the tip 621 of the main bone 6 is presented. As shown in FIG. 20, the improved umbrella tip 601 is formed with a fitting recess 623 formed at the tip 621 of the main bone 6 and at the base end 611 of the tip 601 with a rounded tip. A fitting protrusion 610 that can be moved up and down to be fitted in a fitting recess 623 formed in the tip 621 of the master bone 6 is provided at a predetermined position of the fitting hole 612, and the tip of the master bone 6 that is inserted into the tip 601. The fitting recess 623 formed in 621 is fitted and fixed to the fitting protrusion 610 to fix the tip 601 to the tip 621 of the main bone 6 and prevent the tip 601 from coming off, The fixing structure of the tip 601 is The tip 601 must be provided with a fitting protrusion 610 that can be moved up and down, and is not suitable for mass production because it has a complicated structure, and there is only one fitting recess 623 formed in the tip 621 of the main bone 6. Therefore, the fixation is extremely unstable, and it may be a problem that some looseness is felt during normal use. However, in strong winds, the main bone 6 is reversed and the tip 601 is removed from the tip 621. In this case, since the tip portion 621 is a fine tip structure processed based on the metal main bone 6 bent into a U shape, it is very dangerous and problematic to expose this portion. .

  Next, the best mode of the present invention will be described with reference to the drawings.

  FIG. 1 shows a preferred embodiment of the present invention. Basically, a middle bar having a handle 1 attached to one end and an upper wheel 3 attached to the other end via a stone claw 2. 4, a slide wheel 5 is slidably mounted, and a plurality of master bones 6 are pivotally supported at their proximal ends with a circumferential interval so as to be openable and closable around the top skull 3. 5 is an umbrella in which a sub-bone 7 is formed so as to be pivotally supported at both ends, and an umbrella cloth 8 is stretched over the plurality of main bones 6 via a tip 601.

  In the present embodiment, the main bone 6 is held at a predetermined position on the distal end side relative to the pivotal support position of the secondary bone 7, and the main bone 6 that is always divided into the distal end portion 61 and the proximal end portion 62 is linearly held to hold the umbrella. An outer direction reversing hinge 9 that allows the front end 61 of the main bone 6 to be reversed to the outside as shown in FIG. When the umbrella cloth 8 receives wind pressure of a predetermined pressure or more from the outside direction, the inner direction reversing hinge 10 capable of reversing the tip 61 of the main bone 6 inward as shown in FIG. It is juxtaposed in the direction.

  2 shows the case where both the outer direction reversing hinge 9 and the inner direction reversing hinge 10 are installed. However, either the outer direction reversing hinge 9 or the inner direction reversing hinge 10 may be installed. In general, the case where the outer direction reversing hinge 9 is installed is more effective and easier to arrange when the tension of the umbrella cloth 8 is taken into consideration.

  And, for example, when using the outer direction reversing hinge 9 according to the present invention and joining the main bone 6 and the sub bone 7, the sub bone when the umbrella cloth 8 receives a wind pressure of a predetermined pressure or more from the inner direction. Before the joint between the joint 7 and the main bone 6 is damaged, the outer direction inversion hinge 9 is bent outward so that the wind pressure applied to the umbrella cloth 8 can be released.

  Of course, when the reverse inner direction inversion hinge 10 is attached to the main bone 6, it goes without saying that the wind pressure applied to the umbrella cloth 8 is released by the reverse action, and in the present embodiment, the outer direction inversion hinge 9 is based. Although it arrange | positioned at the end side, you may arrange | position the inner side inversion hinge 10 in the base end side.

  FIG. 3 shows a preferred embodiment of the outer direction reversing hinge 9 used in the present invention. A cylindrical groove formed by an elastic material and having an insertion groove 91 that is narrower than the diameter in the reversing direction is shown. A keyhole-shaped base 92 having both ends of straight lines formed in parallel with the formed cross section and a diameter capable of passing through the insertion groove 91 formed in the base 92 by being pivotally attached to the base 92 by a predetermined pressing force. The base end portion 62 and the distal end portion 61 of the main bone 6 formed by the columnar reversing member 93 and divided into the base end 95 of the base portion 92 and the base end 96 of the reversing member 93 are respectively inserted and fixed. Very easy.

  In this embodiment, normally, as shown in FIGS. 3A and 3C, the reversing member 93 is inserted into the base 92 in the axial direction. When a pressing force in the outward direction is applied to the member 93, the reversing member 93 rotates beyond the insertion groove 91 about the shaft support portion 94 as shown in FIG. 3B. In the state where the umbrella is opened as shown in FIG. 1, the outside direction reversing hinge 9 is in a state in which the reversing member 93 is held in a fitted state on the semi-cylindrical base, and the main bone 6 is in a substantially straight state. It can be used in the same manner as a normal umbrella, and when the wind pressure acts on the umbrella cloth 8 from the inside as shown in FIG. By the action, the reversing member 93 is reversed to the outside beyond the insertion groove 91. As shown in FIG. 2 (b), when the wind pressure of a predetermined level or more acts on the umbrella cloth 8 from the outside, the main bone 6 is bent by the action of the inner direction reversing hinge 10, as shown in FIG. When the reversing member 93 is reversed inward beyond the insertion groove 91, the reversing member 93 is bent inward to prevent the main bone 6 from being damaged.

  Therefore, as shown in FIG. 2 (a), when the main bone 6 receives wind pressure exceeding the tension necessary for maintaining the open state by the main bone 6 and the umbrella cloth 8, the tip 61 portion of the main bone 6 is inverted outward or inward. As a result, the wind pressure on the umbrella cloth 8 is reduced, and damage to the main bone 6 or the umbrella cloth 8 can be prevented.

  As described above, by providing the outer direction inversion hinge 9 or the inner direction inversion hinge 10 at a predetermined position of the main bone 6, the main bone 6 is inverted without forcibly withstanding the wind pressure, and thus holds the umbrella. There is no worry of overloading the person, and it is extremely safe without being pulled or falling, and the umbrella itself is not thrown away.

  In the present embodiment, the resistance of the reversing member 93 is determined by the elasticity of the base 92, the width of the insertion groove 91 formed in the base 92, the height of the wall, the diameter of the base 92 and the reversing member 93, etc. The force for holding the distal end portion 61 and the proximal end portion 62 of the master bone 6 in a straight line can be adjusted appropriately. When the inverted umbrella is reopened and restored, the master bone is locked in its original state, and then When stored, the parent bone can be held in its original straight shape.

  Here, not only the outer direction reversing hinge 9 but also the inner direction reversing hinge 10 arranged in parallel in the axial direction in the main bone 6 can be used with the same configuration as the outer direction reversing hinge 9 reversed. However, since the tension of the umbrella cloth 8 does not act when holding the distal end portion 61 and the proximal end portion 62 in a normal use state, the inner direction inversion hinge 10 needs a mechanism having a necessary holding force alone. Since the reversal start is caused by exceeding the pressing force of the locking portion, a reversal adjustment different from the outward reversal hinge is required. Therefore, it is preferable to select or adjust the pressing force at the time of starting reversal between the inner direction reversing hinge 10 and the outer direction reversing hinge 9 for use.

  Further, FIG. 4 is an example in which the inner direction inversion hinge 10 and the outer direction inversion hinge 9 shown in FIG. 3 are integrated as one united base 97, and a cut piece (not shown) of the parent bone 6 is provided in the middle. Since there is no need to sandwich the parts, the number of parts is small and manufacturing is easy.

  FIG. 5 shows the operation of the embodiment of the hinge shown in FIG. 4 in use, FIG. 5 (a) shows a normal state, and FIG. 5 (b) shows the parent bone 6 with wind pressure applied from the inside. FIG. 5C shows an action state when the wind pressure is applied from the outside and the main bone 6 is inverted inside.

  Further, FIG. 6 shows a different embodiment of the outward direction reversing hinge 9 used in the present invention, which is formed of a hard synthetic resin material having an appropriate elasticity, and a base end portion 62 of the main bone 6 at a base end 96. Is inserted and fixed, and the cross-section in which the insertion groove 91 is formed on the upper surface has a U-shaped section with a top opening, and the insertion groove 91 formed on the base 92 by being pivotally attached to the base 92 by the shaft support 94. And a columnar reversing member 93 in which the distal end portion 61 of the main bone 6 is inserted and fixed to the base end 95. In particular, in this embodiment, the insertion groove 91 formed in the base portion 92 is formed. A pair of locking projections 921 and 921 project from a predetermined position on the inner surface opposite to each other via the reversing member 93, and the reversing portion is located at a position overlapping the locking projection 921 on both side surfaces of the reversing member 93. 93 is tilted and inserted into the insertion groove 91 of the base 92 so that the base end 61 of the main bone 6 and the base end 62 and the front end 61 of the main bone 6 in the direction of the reversing member 93 are coaxial. Locking protrusions 931, 931 that protrude over the locking protrusions 921, 921 protruding from the insertion groove 91 of the 92 and lock each other are protruded on both sides of the reversing member 93.

  Therefore, normally, as shown in FIG. 6A, the base end portion 62 and the distal end portion 61 of the main bone 6 are coaxially formed to form a use state. For example, the locking projection 931 gets over the locking projection 921 from the inside. As described above, the degree of locking between the locking projection 921 and the locking projection 931 is to prevent the main bone 6 from being damaged by releasing the locking state and reversing the reversing member 93 to release the wind pressure. The reversing member 93 once reversed as shown in FIG. 6 (b) by setting it to be equal to or lower than the tension of the main bone 6 and the umbrella cloth 8 when the umbrella is opened, only opens the umbrella again. 6 (a) is simply re-engaged, and the main bone 6 is held in its original position even after the umbrella is stored. When reusing it, you just need to open the umbrella as usual, which is very convenient.

  The relationship between the tension and the wind pressure for reversing the reversing member 93 is the same for the other embodiments of the present invention.

  FIG. 7 shows different embodiments of the outer direction inversion hinge 9 or the inner direction inversion hinge 10 according to the present invention, and the outer direction inversion hinge 9 and the inner direction inversion hinge 10 are each a hard composite having appropriate elasticity. A pair of bottomed cylinders 12, 13 made of resin and having a mounting opening 11 for the main bone 6 are connected by a connecting body 14, and the locking holes 121 formed on the bottom surface of one of the cylinders 12 are already connected. A stepped protrusion 122 formed on the bottom surface of one cylindrical body 13 is connected to be removable.

  In a normal use state, as shown in FIG. 7 (b), the stepped protrusions 122 of the one cylinder 13 are fitted into the locking holes 121 of the other cylinder 12 so that both the cylinders 12 and 13 are fitted. The distal end portion 61 and the proximal end portion 62 of the main bone 6 attached to the attachment ports 11 and 11 in a straight shape are held in a substantially straight shape to obtain a normal use state. For example, when wind pressure of a predetermined pressure or more is applied from the inside The stepped protrusions 122 of both the cylinders 12 and 13 come out of the locking holes 121 and bend around the connecting body 14, thereby preventing the parent bone 6 from being damaged.

  Further, by fitting the stepped protrusion 122 of the cylindrical body 13 into the locking hole 121 of the other cylindrical body 12 again from the bent state, the parent bone 6 returns to the original substantially straight line.

  The outer direction inversion hinge 9 and the inner direction inversion hinge 10 shown in the present embodiment have a very simple configuration, can be integrally formed, can be provided at low cost by mass production, and are durable. Also excellent in properties.

  FIG. 8 shows a case where a double hinge structure in which the outer direction inversion hinge 9 and the inner direction inversion hinge 10 shown in the embodiment of FIG.

  FIG. 9 is a partially enlarged view of the stepped protrusion 122 used for the embodiment shown in FIGS. 7 and 8. FIG. 9 (a) has a flange-like step. 9 (b) shows a spherical stepped portion, but it is of course an example and is not limited to these shapes.

  In addition, FIGS. 10 (a) and 10 (b) show the outer direction inversion hinge 9 and the inner direction inversion hinge 10 with respect to the embodiment shown in FIGS. Are formed integrally with the distal end portion 61 and the proximal end portion 62 of the main bone 6 by the same material.

  According to this embodiment, since the main frame 6 of the umbrella can be integrally formed, an assembling operation is not necessary, and it is advantageous in terms of productivity, strength and durability.

  In addition, the inner direction inversion hinge 10 and the outer direction inversion hinge 9 described here are examples, and a conventionally known hinge can be used as long as it can be attached to the main bone 6 and can be inverted with a predetermined functional structure. Needless to say, you can.

  In addition, although all of the present embodiments have been described with respect to a non-folding umbrella, the present invention also applies to a folding umbrella, particularly when the folding main bone 6 is fixed in an extended state when opened. It is possible (not shown), and by implementing the present invention closer to the distal end side than the folding structure of the main bone 6, the functions and effects of the present invention can be exhibited.

  FIG. 11 shows an embodiment of a preferred tip 601 for carrying out the present invention. The configuration of the entire umbrella is similar to the conventional general umbrella shown in FIG. Umbrella 8 is stretched around a plurality of main bones 6 that are attached to the outer periphery of an upper wheel 3 arranged at the front end of an intermediate shaft 4 that is pivotably attached to the outer periphery of the center shaft 4 and that can be opened and closed. For example, the distal end portion 63 of the main bone 6 formed of a synthetic resin having an inner diameter is inserted into an insertion hole 612 formed in the proximal end portion 611 of the tip 601 with a rounded distal end formed of a synthetic resin material having appropriate elasticity. It is inserted and fixed.

  In the present embodiment, the main bone 6 is formed of a synthetic resin material such as glass fiber having appropriate elasticity and rigidity, and the tip 621 is formed at the base end 611 of the tip 601. A pair of locking projections 622 and 622 for locking when the tip portion 621 is inserted into the fitting insertion hole 612 protrudes in the vertical direction across the axis, and The engaging recesses 613 and 613 are through walls through which the engaging projections 622 and 622 are fitted when the tip 622 of the main bone 6 is inserted into the wall surface of the fitting insertion hole 612, respectively. It is formed so as to penetrate.

  As described above, in the present embodiment, the locking protrusions 622 and 622 formed on the tip 621 of the parent bone 6 are simply inserted into the fitting insertion hole 612 of the tip 601 of the tip 621 of the tip 601 of the tip 601. Since it is fitted and locked in the locking recesses 613 and 613 formed in the fitting hole 612, it is securely fixed.

  In particular, as shown in FIG. 12, in the present embodiment, the locking projections 622 and 622 projecting from the main bone 6 have an inclined surface 6221 formed forward in the distal direction and a vertical surface 6222 in the proximal end. It is formed and is a triangular frustum that is flat at the tip and thin in the tip direction, and exerts the action and effect that it is easy to enter the locking recesses 613 and 613 and is difficult to come off.

  Further, in the present embodiment, the locking projections 622 and 622 formed on the main bone 6 and the locking recesses 613 and 613 of the tip 601 are arranged opposite to each other at symmetrical positions across the axis, It can be securely fixed without rattling as in the conventional example having a structure that is later locked in one place. Furthermore, by adjusting the positions of the locking projections 622 of the master bone 6 and the locking recesses 613 of the tip 601 and providing sufficient insertion allowance, the main bone 6 can be swung around the locking projections 622 as a fulcrum. Since it does not move, it is possible to fix the tip 621 and the tip 601 more reliably.

  In addition, in the present embodiment, both the main bone 6 and the tip 601 are formed of a synthetic resin having elasticity, but the main bone 6 is relatively hard due to the function of stretching the umbrella cloth 8. The tip 601 should be able to be inserted into the parent bone 6 and should not be damaged even if it hits the tip, and is preferably selected to be softer than the parent bone 6.

  Furthermore, in the present embodiment, the tip 601 is made of a thermoplastic resin, and a protruding piece 614 for fastening the umbrella cloth 8 is provided along the base end portion 611 by integral molding. Although it has an advantage that the cloth 8 can be fixed by welding, as another embodiment, a seam hole can be formed in the protruding piece 614 to correspond to the cloth umbrella cloth 8. (Not shown).

  FIG. 13 and FIG. 14 show different embodiments of the present invention, and a circular collar shape in which a locking projection 622 of a tip portion 621 formed on the main bone 6 projects over the periphery at a predetermined position of the main bone 6. It is formed by fixing what is formed integrally or separately with the main bone 6, and is fitted and locked in an annular locking recess 613 formed in the fitting insertion hole 612 of the tip 601. Since it fits over the circumference | surroundings of the predetermined position of the main bone 6, even if force is added to the main bone 6 from all directions, there is no worry that the tip 601 will come off.

  15 and 16 show different embodiments of the tip 601 and the tip portion 621 of the present invention. The tip 601 is substantially the same as the embodiment shown in FIGS. However, the difference is that the main bone 6 is metallic with a cylindrical shape, and the locking projection 622 is arranged at a predetermined position of the tip 621.

  The actions and effects in the present embodiment are almost the same as those of the embodiment shown in FIGS. 11 to 14, and in particular, the metal main bone 6 that is not sufficiently effective in the adhesive is securely fixed only by being inserted. It is useful because it can.

  17 and 18 show still another embodiment of the tip 601 and the tip portion 621 of the present invention. The main bone 6 is made of a synthetic resin material having appropriate elasticity and rigidity such as glass fiber. The tip 621 is formed with a protruding projection 622 formed of a spherical bulge, and the tip 601 made of synthetic resin or hard rubber protrudes from the base end 611 for fastening an umbrella cloth. A piece 614 is protruded by integral molding, and a locking recess 613 is formed in the main body to fit and lock the tip 621 of the main bone 6 including the locking protrusion 622 of the main bone 6.

  In particular, in the present embodiment, the locking recess 613 includes the space 6131 having a length and a width that allow the tip 621 of the main bone 6 having the locking protrusion 622 of the main bone 6 to move in the axial direction, and the space. A shaft hole 6132 that communicates with the portion 6131 and communicates with the base end portion 611 of the tip 601 and that is wider than the shaft diameter of the main bone 6 and narrower than the locking projection 622 penetrates the base end portion 611. An insertion groove 6133 that is formed and has substantially the same shape as the tip 621 of the main bone 6 is formed on the surface side so as to communicate with the space 6131.

  In the present embodiment, an umbrella cloth (not shown) is fixed to a protruding piece 614 that is fixed to an umbrella cloth protruding from a base end portion 611 of the tip 601 by welding or a thread, and the tip portion 621 of the main bone 6 is fixed. The tip portion 621 including the locking projection 622 of the main bone 6 is inserted into the insertion groove 6133 and loosely fitted into the space portion 6131, and the front portion 621 of the main bone 6 is inserted into the shaft hole 6132. At this time, the tip 601 is pulled to the proximal end side of the main bone 6 by the tension of the umbrella cloth welded to the projection piece 614 for fastening the umbrella cloth, so that the locking projection 622 is formed on the distal end side of the space portion 6131 of the tip 601. The position of the locking projection 622 moves from the insertion groove 6133 and does not come off, and the tip 601 is fixed to the main bone 6.

  Further, in the present embodiment, the space 6131 is formed not only at the tip of the engaging recess 613 of the insertion groove 6133 but also at the base side, so that, for example, the engaging protrusion 622 even when the main bone 6 is inverted. Does not move out to the base end side. Furthermore, in the present embodiment, the insertion groove 6133 is formed on the surface, but if it is formed on the side surface, it is more difficult to come out (not shown).

  The dew 601 integrated with the protruding piece 614 on which the umbrella cloth 8 is welded or sewn can be easily removed from the main bone 6 by intentionally adjusting the position of the locking projection 622 to the insertion groove 6133. The cloth 8 can be easily removed.
