Description

  The present invention relates to an overhang prevention device that prevents an umbrella from protruding in the width direction when the umbrella is moved, an umbrella equipped with the overhang prevention device, and a method of using the umbrella equipped with the overhang prevention device.

As a device that can easily prevent rain when a bicycle is being driven, a bicycle umbrella support for fixing an umbrella for everyday use to a handle as in Patent Document 1 has been proposed.
The bicycle umbrella support includes a bracket fixed to a bicycle handle, a support rod fixed to the bracket and extending vertically upward, and a holder attached to the tip of the support rod. The gripping part is clamped.

Japanese Patent Laying-Open No. 2005-324751

In the method of using the umbrella described in Patent Document 1, when the bicycle and the pedestrian pass each other, the umbrella projects in the width direction of the bicycle (perpendicular to the traveling direction), so that the tip of the umbrella hits. Pedestrians may be injured. For this reason, the dimension in the width direction of the umbrella when it is fixed to the bicycle (hereinafter simply referred to as “width dimension”) is regulated to be a predetermined dimension or less with respect to the width dimension of the bicycle itself.
For example, in the Road Traffic Law, the upper limit of the width dimension of a bicycle is set to 60 cm. In some local governments, road traffic rules may be established, and the upper limit of the width of the umbrella when fixed to the bicycle may be defined as the width of the bicycle +30 cm. That is, when the width dimension of the bicycle is 60 cm, the upper limit of the umbrella width dimension is 90 cm. However, since adult umbrellas used in daily life have a diameter of approximately 100 cm or more, if they are mounted on a bicycle as they are, the size of the umbrella will greatly exceed the size stipulated in the regulations, which is against the law. In some cases, it was subject to criminal action. For this reason, when mounting an umbrella on a bicycle, it was necessary to use an umbrella that was smaller than an umbrella used daily.

  However, when leaving the bicycle, the umbrella is kept attached to the bicycle, or the umbrella is removed from the bicycle and used as an umbrella for walking. When the diameter of the umbrella is small as described above, there is a problem that rain falls on the body and gets wet during walking. For this reason, there is an inconvenience that two types of umbrellas, that is, an umbrella to be attached to the bicycle and an umbrella to be used when the bicycle is not used must be used.

  In view of the above situation, the purpose of the present invention is to make it possible to comply with laws and regulations such as the Road Traffic Act by reducing the size of the umbrella in the width direction when mounted on a bicycle even if it is used everyday. To provide an overhang prevention device, an umbrella equipped with the overhang prevention device, and a method of using the umbrella equipped with the overhang prevention device.

  One form of the overhang prevention device according to the present invention is formed of an intermediate rod, an upper skull fixed to an end portion of the intermediate rod, a lower skull movable freely along the middle rod, and an elastic body. A plurality of master bones, one end of which is flexibly connected to the upper crossbone, radially extending in the radial direction, one end of the plurality of master bones being connected to a substantially center in the longitudinal direction, and the other end thereof connected to the bottom crosspiece. An overhang prevention device that is used in an umbrella having a plurality of receiving bones that are flexibly connected to each other and an umbrella cloth stretched between the parent bones to prevent the parent bones from protruding outward in the radial direction. A first locking member that is slidable on the middle rod between the upper and lower pockets, and at least a pair of the main bones facing each other in one direction across the middle rod. A plurality of second locking members each locked to a radially outer end; A plurality of coupling bodies each having an end coupled to the first locking member and the other end coupled to the plurality of second locking members, the first locking member and the second locking member Is smaller than the distance between the first locking member locked to the middle rod when the umbrella is opened and the radially outer end of the main bone.

  One form of the umbrella according to the present invention is an umbrella equipped with the above-described overhang prevention device, and is freely movable along the center bar, an upper arm fixed to the end of the center bar, and the center bar. A plurality of main bones formed of an elastic body, one end of which is connected to the upper crossbone so as to be bent, and radially extending in the radial direction, and one end bent to a substantially central portion in the longitudinal direction of the plurality of main bones. A plurality of bones that are connected to each other and bendable to the lower ring, and an umbrella cloth stretched between the parent bones, and the first locking member comprises: At least a pair of the main bones that are slidably slidable on the middle rod between the upper and lower pockets, and a plurality of the second locking members are opposed in one direction across the middle rod. When the umbrella is opened and locked in the radially outer end, the one direction Diameter dimension is characterized by smaller than the direction of the diameter perpendicular to the one direction.

  One form of usage of the umbrella according to the present invention is a method of using an umbrella equipped with the overhang prevention device, wherein the one direction is substantially orthogonal to the traveling direction of the bicycle when attached to the bicycle. It is featured in that it is attached in the direction to be.

  According to the present invention, even if it is an umbrella used everyday, when it is mounted on a bicycle, the width direction of the umbrella can be reduced to comply with laws and regulations such as the Road Traffic Law. The attached umbrella and the usage method of the umbrella equipped with the overhang prevention device can be provided.

It is the schematic diagram which looked at the umbrella of 2nd Embodiment of this invention from the perpendicular direction upper direction.

Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a state in which an umbrella 10 (hereinafter simply referred to as “umbrella”) equipped with an overhang prevention device according to an embodiment of the present invention is fixed to a handle 90 of a bicycle 96. 91 is an umbrella support. The umbrella support 91 has a bracket 92 fixed to the handle 90, a support bar 93 fixed to the bracket 92 and extending vertically upward, and a holder 94 attached to the tip of the support bar 93. The umbrella 10 is fixed to the bicycle 96 by holding the grip 70 of the umbrella 10 with a holder 94. Details of how to use the umbrella 10 will be described later.

  Next, an embodiment of the umbrella 10 (hereinafter referred to as “first embodiment”) will be described. FIG. 2 is a schematic view of a state in which the middle bar 12 is cut in the longitudinal direction when the umbrella 10 is opened. In the following description, the upper side (the side of the stone bump 68) in FIG. 2 is referred to as the upper side in the vertical direction, and the opposite side (the side of the grip portion 70) is referred to as the lower side in the vertical direction. The direction perpendicular to the longitudinal direction of the center rod 12 is referred to as “radial direction”, the direction around the center rod 12 around the periphery is referred to as “circumferential direction”, and the direction away from the center rod 12 in the radial direction is referred to as “diameter direction”. "Direction out of direction".

  The umbrella 10 includes a middle rod 12, an upper skull 14 fixed to an end of the middle rod 12 in the vertical direction, a lower skull 16 assembled to the middle rod 12 vertically below the upper skull 14, and a plurality of umbrellas 16. It has a master bone 18 and a plurality of receiving bones 20. Further, an overhang prevention device 30 is provided for preventing overhang of the tip of the main bone 18 when the umbrella 10 is opened.

  The middle rod 12 is formed in a straight hollow pipe shape using a metal material such as iron. In the middle bar 12, a stone protrusion 68 is installed on the tip side further upward in the vertical direction than the upper handle 14. A gripping portion 70 is fixed to the end of the middle rod 12 in the vertical direction.

The upper wheel 14 is made of synthetic resin and has a substantially cylindrical shape, and is fixed coaxially with the center rod 12. One end of the main bone 18 in the longitudinal direction is connected to the outer peripheral cylindrical surface at equal intervals in the circumferential direction. Each of the main bones 18 is connected to the upper handle 14 with a pin and can be bent in the direction of the center rod 12. In the first embodiment, the number of parent bones 18 is eight (see FIG. 4). When the umbrella 10 is opened, the main bone 18 extends radially in the radial direction. Umbrella cloths 22 (see FIG. 1) are stretched between the main bones 18 adjacent in the circumferential direction.
The main bone 18 is made of a thin steel plate made of iron or stainless steel. The main bone 18 has a U-shaped cross section in a direction perpendicular to the longitudinal direction, and is incorporated in a direction that opens downward in the vertical direction in the umbrella 10 of the first embodiment. The main bone 18 may be any material that can be bent in a direction perpendicular to the longitudinal direction, and a synthetic resin material reinforced with glass fiber, carbon fiber, or the like is appropriately selected in addition to the above-described metal material such as iron. sell.

The bottom pole 16 is made of synthetic resin and has a substantially cylindrical shape. The bottom rail 16 is fitted coaxially with the outer periphery of the middle bar 12 and a gap so that it can slide along the middle bar 12. One end in the longitudinal direction of the receiving bone 20 is connected to the cylindrical surface of the outer periphery of the lower wheel 16 at equal intervals in the circumferential direction. Each of the bones 20 is connected to the lower crosspiece 16 with a pin and can be bent in the direction of the center rod 12.
The other end in the longitudinal direction of each of the bones 20 is connected to a connecting portion 19 provided at substantially the center in the longitudinal direction of the parent bone 18 by a pin, and the receiving bone 20 and the parent bone 18 can be bent with respect to each other.
The receiving bone 20 is made of a thin steel plate made of iron or stainless steel. The receiving bone 20 has a U-shaped cross section orthogonal to the longitudinal direction, and is incorporated in a direction that opens downward in the vertical direction.

When opening the umbrella 10, the bottom 16 is pushed upward in the vertical direction. As a result, each of the main bones 18 is pushed radially outward in a direction away from the center rod 12 by being pushed by the receiving bone 20.
The umbrella cloth 22 is stretched between the parent bones 18. Generally, the size in the circumferential direction of the umbrella cloth 22 attached between the adjacent main bones 18 is smaller than the interval in the circumferential direction between the adjacent main bones 18 on the outer side in the radial direction of the umbrella 10. Accordingly, when the umbrella 10 is opened, the main bone 18 has a shape that is bent in a curved manner toward the grip portion 70 as it goes outward in the radial direction.

Next, an embodiment of the overhang prevention device 30 will be described.
FIG. 3 is a perspective view showing the shape of the overhang prevention device 30. The overhang prevention device 30 includes a first locking member 32 that is externally fitted to the intermediate rod 12, a pair of connecting bodies 34, 34 having one end connected to the first locking member 32, and each connecting body 34, 34 and the second locking members 36 and 36 connected to the other end.

  The first locking member 32 is made of a synthetic resin such as polyamide, and is formed by facing a pair of structural members 49 and 50 having substantially the same shape. The component member 49 includes a semi-annular portion 38 having an arc-shaped cross section perpendicular to the axis m, and a pair of flat plate portions 39 and 39 formed at both ends of the semi-annular portion 38 in a direction away from the axis m. Has been. Each flat plate portion 39, 39 is provided with two screw holes (not shown) penetrating in the thickness direction. A rib 41 protruding in the radial direction is formed on the outer periphery of the semi-annular portion 38, and a hole 42 penetrating in the thickness direction is provided in the rib 41. Since the component member 50 has substantially the same shape as the component member 49, description thereof is omitted.

  The second locking member 36 is made of a synthetic resin such as polyamide, and has a cylindrical main body portion 47 having a bottomed cylindrical hole 45 and a plate-like rib 43 integrally formed on the outer peripheral cylindrical surface. It consists of and. The rib 43 is provided with a hole 44 penetrating in the thickness direction.

  The coupling body 34 is a string-like member made of nylon, for example. One end of the coupling body 34 is coupled to the hole 42 of the first locking member 32, and the other end is coupled to the hole 44 of the second locking member 36. The length of the coupling body 34 is set to a length that allows the radially outer end 54 of the main bone 18 to be drawn toward the middle rod 12 when the umbrella 10 is opened. Details of the length of the coupling body 34 will be described later.

The mounting state of the overhang prevention device 30 in the umbrella 10 according to the first embodiment will be described with reference to FIGS. 2 and 3 again.
The first locking member 32 is attached to the intermediate rod 12 between the upper and lower skulls 14 and 16 (see FIG. 2). At this time, the pair of constituent members 49 and 50 are combined so that the concave portions of the semi-annular portion 38 face each other with the middle rod 12 interposed therebetween. And the 1st latching member 32 is fixed to the center rod 12 by fastening the flat plate part 39 of each structural member 49 and 50 which mutually faced with the screw 52 (refer FIG. 3). At this time, the inner diameter dimension of the cylindrical slide surface 33 formed by the semicircular ring portions 38 facing each other is slightly larger than the outer diameter dimension of the intermediate rod 12. Therefore, the first locking member 32 can freely move in the longitudinal direction along the middle rod 12. In addition, the 1st latching member 32 should just be able to be easily moved with respect to the center rod 12 by the hand or the elasticity of the main bone 18 mentioned later. Therefore, the inner diameter dimension of the slide surface 33 is approximately the same as or slightly smaller than the outer diameter dimension of the intermediate rod 12 and may have a slight sliding friction resistance when moved.

Next, a method for mounting the second locking member 36 will be described.
When the second locking member 36 is attached to the radially outer end 54 (hereinafter referred to as “dew point”) of the main bone 18, the opening of the cylindrical hole 45 faces the dew point 54 in the radial direction of the umbrella 10. Let go outside. As will be described later, the pair of second locking members 36 and 36 are externally fitted to the respective tips 54 of the pair of main bones 18 that are opposed to each other with the intermediate rod 12 interposed therebetween.
The second locking member 36 is attached to the tip 54 with the umbrella 10 closed. As shown in FIG. 5, the first locking member 32 can slide toward the gripping portion 70, so that the first locking member 32 and the tip 54 can be brought close to each other.
Since the inner diameter of the cylindrical hole 45 is larger than the outer diameter of the tip 54, it can be easily mounted. Further, the cylindrical hole 45 has a bottom, and when the second locking member 36 is attached, the tip of the dew point 54 contacts the bottom surface of the cylindrical hole 45. The umbrella cloth 22 is generally attached inward in the radial direction from the tip 54, so that the depth of the cylindrical hole 45 is made shallower than the length of the tip 54, so The member 36 does not come into contact. For this reason, when the 2nd locking member 36 is fitted to the tip 54, the malfunction that the umbrella cloth 22 is torn can be prevented.

Next, the deformation state of the main bone 18 when the overhang prevention device 30 is attached and the umbrella 10 is opened will be described with reference to FIG.
When the overhang prevention device 30 is attached and the umbrella 10 is opened, the tip 54 is drawn toward the center rod 12 and the main bone 18 is bent radially inward. In FIG. 2, the solid line 18 shows the shape when the parent bone 18 is bent radially inward by mounting the overhang prevention device 30. In addition, the shape of the main bone 18 when it is assumed that the overhang prevention device 30 is not attached is indicated by a broken line. For convenience of explanation, the position of the tip 54 when the overhang prevention device 30 is not attached is R0, and the position of the tip 54 when the overhang prevention device 30 is bent inward in the radial direction is R1. And

When the umbrella 10 is opened, the bottom 16 is pushed upward in the vertical direction. Since the first locking member 32 is fitted to the center rod 12 coaxially with the lower wheel 16, the first locking member 32 is pushed upward in the vertical direction at the same time as the lower wheel 16 is pushed up.
At this time, in the overhang prevention device 30, the distance L1 between the first locking member 32 and the second locking member 36 is such that the first locking member 32 locked to the middle rod 12 when the umbrella 10 is opened. , R0 is smaller than the distance L0 with the dew tip 54 where the second locking member 36 is locked. The distance L1 is a dimension when the connecting body 34 is stretched.
In the overhang prevention device 30, the distance L1 needs to be substantially smaller than the distance L0 in order to draw the tip 54 at the position R0 inward in the radial direction. Therefore, the distance L1 is measured at a position corresponding to the distance L0. For example, the position of the first locking member 32 when measuring the distance L0 and the position of the second locking member 36 when measuring the distance L1 correspond to each other. Measured at the site. Similarly, the position of the second locking member 36 corresponding to the position of the tip 54 is the same as the position of the specific portion of the tip 54 when the second locking member 36 is attached to the tip 54. The position of the part.

In this way, the tip 54 that has locked the second locking member 36 is drawn inward in the radial direction. At this time, the main bone 18 is supported by the receiving bone 20 at the connecting portion 19. Even when the tip 54 is pulled radially inward by the overhang prevention device 30, the position of the connecting portion 19 is hardly displaced. Therefore, as shown in FIG. 2, in the main bone 18, a portion radially outward from the connecting portion 19 is bent inward in the radial direction. Since the main bone 18 is formed of an elastic body, it can be easily bent without plastic deformation.
The displacement amount p when the tip 54 is drawn inward in the radial direction can be adjusted by changing the length of the coupling body 34, and the displacement amount p becomes smaller as the length of the coupling body 34 becomes shorter. growing. The displacement amount p is the distance between the tip 54 at the position R0 and the tip 54 at the position R1. At this time, the first locking member 32 is pulled downward in the vertical direction by the elastic force of the deformed main bone 18 to be restored to the original shape, and is in contact with the bottom rail 16.

  Further, when the main bone 18 is deformed in this manner, the direction of the tip 54 at the position R1 is directed downward in the vertical direction compared to the direction of the tip 54 at the position R0. Therefore, since the tip of the main bone 18 of the umbrella 10 does not protrude outward in the radial direction, even when approaching a pedestrian while holding the umbrella 10, it is possible to pass safely.

  FIG. 4 is a schematic view of the umbrella 10 of FIG. 2 viewed from above in the vertical direction. The shape and size of the umbrella 10 of the first embodiment will be specifically described with reference to FIG. The umbrella 10 before mounting the overhang prevention device 30 has the same diameter dimension D0 in each radial direction. In general, the diameter dimension D0 of an adult umbrella is about 100 cm to 110 cm. As an example, an umbrella 10 (referred to as Example 1) having a diameter D0 of 110 cm will be described.

The pair of second locking members 36, 36 are attached to the respective tips 54, 54 of the two main bones 18, 18 located at positions facing each other with the middle rod 12 in between. In FIG. 4, the second locking members 36 and 36 are attached to the tips 54 and 54 at positions C and G. FIG. 4 shows a state in which the position of the tip 54 is drawn inward in the radial direction by the overhang prevention device 30 in the directions C and G, and the position of the tip 54 before being drawn is indicated by a broken line. Show. In the main bone 18 in the direction C, a connecting portion 19 with the receiving bone 20 is formed at a substantially center in the longitudinal direction, and the main bone 18 is deformed radially inward from the connecting portion 19 and radially inward. doing.
FIG. 4 shows a state where the tip 54 at the position C is pulled inward in the radial direction and moved to a line connecting the tip 54 of B and the tip 54 of D. The position of the tip 54 at this time is C1. Similarly, in the main bone 18 in the G direction, the tip 54 is pulled to the position of G1.
Thus, the diameter D1 of the umbrella 10 in the direction pulled radially inward by the second locking member 36 is the distance between the B tip 54 and the H tip 54 (or the D tip 54). And the distance between F and the tip 54). The number of the main bones 18 is 8, and the angle formed by the adjacent main bones 18 is 45 °. Therefore, the ratio of the distance from B to H and the distance from B to F is 1: √2. From this, the diameter dimension D1 of the umbrella 10 in the directions of C and G is approximately 78 cm (= 110 / √2). Naturally, the position of each dew point 54 except the position of C and the position of G hardly changes by mounting the overhang prevention device 30. Therefore, the diameter dimension D0 in the direction orthogonal to the direction connecting C and G, that is, the direction connecting A and E is 110 cm.
Thus, when the umbrella 10 according to the first embodiment is opened, the diameter dimension D1 in one direction (directions C and G) in which the second locking member 36 is locked is set to a direction orthogonal to the one direction ( It can be made smaller than the diameter dimension D0 in the direction of A and E).

Next, a usage method when the umbrella 10 of the first embodiment is attached to the bicycle 96 and travels will be described. As shown in FIG. 1, the umbrella 10 is fixed to the bicycle 96 with the gripping portion 70 held between the holders 94. In FIG. 1, the traveling direction of the bicycle 96 is indicated by an arrow S. When the umbrella 10 is attached to the bicycle 96, the direction of A and E is attached in the same direction as the traveling direction S. In other words, the second engagement member 36 is attached so that the direction connecting C and G is orthogonal to the traveling direction S of the bicycle 96.
According to road traffic rules established by each local government, it may be stipulated that “the size in the width direction of the umbrella mounted on the bicycle does not exceed the width of the bicycle +30 cm”. The width direction of the bicycle means a direction orthogonal to the traveling direction S. The dimension in the width direction of a general bicycle 96 is 55 cm. In the umbrella 10 of Example 1 described above, the size exceeding the size in the width direction of the bicycle 96 is 23 cm (= 78 cm−55 cm), and thus the size allowed by the road traffic rules.

The C tip 54 is pulled inward from the line connecting the B tip 54 and the D tip 54, and the G tip 54 is connected to the F tip 54 and the H tip 54. Even when it is assumed that the wire is pulled to the inner side from the line connecting the two, the diameter dimension D1 in the directions of C and G is never smaller than 78 cm. This is because the diameter dimension D1 of the umbrella 10 in the C and G directions is determined by the distance between the B tip 54 and the H tip 54 or the distance between the D tip 54 and the F tip 54. .
Therefore, by mounting the overhang prevention device 30, the minimum dimension Ls of the diameter dimension D1 in the width direction of the umbrella 10 is D0 / √2 when the diameter dimension of the umbrella 10 before the overhang prevention device 30 is mounted is D0. It is. On the other hand, when the dimension in the width direction of the bicycle 96 is D, the allowable value DS of the diameter dimension D1 in the width direction of the umbrella 10 is D + 30 cm. In order to comply with the road traffic rules, at least the minimum dimension Ls needs to be smaller than the allowable value DS. For this reason, the umbrella 10 to be mounted on the bicycle 96 may be an umbrella 10 having a diameter dimension D0 before mounting the overhang prevention device 30 smaller than DS × √2.

  Further, in the direction in which the second locking member 36 is attached, the direction of the tip 54 can be directed downward in the vertical direction. For this reason, it can avoid that the front-end | tip of the main bone 18 of the umbrella 10 protrudes toward a pedestrian by mounting | wearing the overhang | projection prevention apparatus 30. FIG. Thus, by using the umbrella 10 of the first embodiment, the bicycle 96 can be run more safely.

  Next, the operation of the overhang prevention device 30 when the umbrella 10 is closed and opened will be described. FIG. 5 is a schematic view of the umbrella 10 according to the first embodiment in a closed state, cut along the center rod 12 in the direction connecting C and G in FIG. 4. In order to avoid complication of the figure, the left half of FIG. 5 shows only the state in which the main bone 18 and the lower ring 16 are connected by the receiving bone 20, and the first locking member 32 and the second locking member. The figure of the connection body 34 which connects 36 is abbreviate | omitted. In the right half of FIG. 5, the illustration of the receiving bone 20 that connects the parent bone 18 and the lower crosspiece 16 is omitted.

When the umbrella 10 is closed, the lower skull 16 moves downward in the vertical direction and is displaced to a position that is substantially in contact with the grip portion 70. At this time, the main bone 18 bent between the connecting portion 19 and the tip 54 is restored to its original shape by elasticity, so that the first locking member 32 is pulled to the tip 54 via the connecting body 34. ing. Since the first locking member 32 is slidably fitted to the middle rod 12, it moves downward in the vertical direction. The position of the first locking member 32 when the umbrella 10 is closed is indicated by a solid line. The position of the first locking member 32 when the umbrella 10 is opened is indicated by a broken line.
When a slight sliding frictional force is generated between the slide surface 33 of the first locking member 32 and the middle rod 12, the first locking member 32 does not fall downward in the vertical direction due to its own weight. Since the first locking member 32 stops descending when the tension of the coupling body 34 is eliminated, the coupling body 34 is not greatly slackened. Thereby, when opening the umbrella 10 again, it can avoid that the connection body 34 gets caught in a hand etc. FIG.

When opening the umbrella 10, the bottom 16 is pushed upward in the vertical direction. As can be understood from FIG. 5, the bottom 16 and the first locking member 32 do not contact until the umbrella 10 is opened to some extent. For this reason, since the coupling body 34 does not become tensioned until the bottom wheel 16 and the 1st latching member 32 contact, the overhang | projection prevention apparatus 30 does not act. Therefore, until the overhang prevention device 30 operates, the umbrella 10 can be opened in the same manner as an umbrella used daily (meaning an umbrella without the overhang prevention device 30 attached).
After the bottom wheel 16 and the first locking member 32 come into contact with each other and the overhang prevention device 30 acts, the first locking member 32 is pushed up together with the bottom wheel 16. At this time, the connecting body 34 is tensioned, and the tip 54 to which the second locking member 36 is attached is pulled inward in the radial direction.

  In this way, the umbrella 10 can be opened and closed by the same operation as that of an umbrella used daily, so that the handling is extremely simple. And in the umbrella of 1st Embodiment, since the connection body 34 is arrange | positioned close to the umbrella cloth 22 above the receiving bone 20 (refer FIG. 2), and it is separated from the person who has the umbrella 10, umbrella It can be used comfortably without being in the way when opening and using 10.

  In this way, even if the umbrella 10 is the same size as an umbrella used everyday, the diameter dimension D1 in the width direction of the umbrella 10 can be reduced by using the overhang prevention device 30 of the first embodiment. I can do it. Therefore, since the dimension in the width direction can be made smaller than the dimension determined by the road traffic rules when mounted on the bicycle 96 or the like, the laws and regulations can be observed. Furthermore, since the direction of the dew tip 54 can be prevented from projecting radially outward on the side where the overhang prevention device 30 is attached, the bicycle 96 can be run more safely.

  Although the umbrella 10 of the first embodiment has been described above, it is not limited to the embodiment described here. For example, the connection body 34 may be made of a wire-like metal or may have a winding device with a built-in mainspring. Moreover, elastic bodies, such as a rubber string, may be sufficient. When the connecting body 34 has a wire shape, the first locking member 32 is supported by the connecting body 34 when the umbrella 10 is closed, so that it is possible to prevent unnecessary dropping. Moreover, the unnecessary slack of the connection body 34 can be eliminated by winding with a winding device. Moreover, by comprising with an elastic body, when opening the umbrella 10, the impact when the overhang | projection prevention apparatus 30 begins to operate | move can be relieve | moderated.

Moreover, 1st Embodiment demonstrated the case where a pair of 2nd locking members 36 and 36 with which it mounts | wears with the position of C and G were provided. However, in the case of an umbrella having a large number of main bones 18, the number of second locking members 36 may be increased.
FIG. 6 is a schematic view similar to FIG. 4 for an umbrella 60 (referred to as the second embodiment) when the number of the main bones 18 is 16. In the overhang prevention device for the umbrella 60, three pairs of second locking members 36 are provided (not shown). In this overhang prevention device, three coupling bodies 34 are connected to each of the pair of holes 42, 42 formed in the first locking member 32. One end of each coupling body 34 on the opposite side of the first locking member 32 is associated with one second locking member 36.
In the second embodiment, as shown in FIG. 6, each second locking member 36 includes three pairs of main bones 18 (specifically, D, N, E, and the like facing each other in one direction across the middle rod 12. Locked to the tips 54 of the main bones 18) at positions M, F and L, respectively. Thereby, the diameter dimension D1 of the umbrella 60 in one direction connecting E and M can be made smaller than the diameter dimension D0 of the umbrella 60 in the direction connecting A and I perpendicular to the one direction.
Thus, the umbrella 60 of the second embodiment is attached by aligning the directions of A and I with the traveling direction S of the bicycle 96, thereby reducing the diameter dimension D1 of the umbrella 60 in the width direction orthogonal to the traveling direction S of the bicycle 96. I can do it. Therefore, as in the first embodiment, the umbrella 60 of the second embodiment can comply with laws and regulations such as road traffic rules.

  Moreover, although illustration was abbreviate | omitted, in FIG. 4, the 2nd latching member 36 may be latched by the tip 54 of each position shown by B, C, F, G. At this time, the diameter dimension of the umbrella 10 can be reduced from the middle rod 12 in one direction connecting the centers of B and C and the centers of F and G. In this case, the direction from the middle rod 12 toward the center of A and H (or the center of D and E) may be used in accordance with the traveling direction S of the bicycle 96.

  Moreover, although the case where the umbrella 10 of 1st Embodiment was used for the bicycle 96 was demonstrated, it is not limited to this. For example, you may use for a wheelchair for a physically handicapped person, a walk auxiliary vehicle, etc. Since these are treated as pedestrians under the Road Traffic Law, it is not illegal even if the umbrellas protrude greatly in the width direction, but the umbrella 10 or the like equipped with the overhang prevention device 30 described in the first embodiment is used. As a result, the overhang in the width direction can be reduced, so that the vehicle can pass more safely. Moreover, you may mount | wear with a stroller and may use it while a pedestrian walks.
