  However, the inventions described in Patent Documents 1 and 2 listed here have complicated structures and are not practically used, but also have problems in terms of safety. That is, in the inventions described in both Patent Documents 1 and 2, there are many pivoting parts that connect parts to each other. It is difficult to support the umbrella stably by loosening. Therefore, the inventions described in these patent documents have a problem of poor durability. Also, if the pivot part becomes weak, when the umbrella is subjected to wind pressure due to wind or the like and a large force is applied to the pivot part, the pivot part may be destroyed and the umbrella may suddenly fall down. There was a problem in terms of safety, because if such a thing happened while driving, a traffic accident could be invited.

  An object of the present invention is to solve such a conventional problem, in which an umbrella is attached to a vehicle body that moves manually on the road, and parts of the umbrella support that avoids personnel riding on the vehicle body from rain and solar radiation. It is an object of the present invention to provide an umbrella support for mounting on a vehicle body that is highly safe and durable by eliminating a pivotally connecting portion.

The present invention is an umbrella support for attaching a vehicle body to a vehicle body that moves manually on the road and avoids personnel riding on the vehicle body from rain or solar radiation. A vehicle body attachment tube that can be detachably connected to the body, a hand support tube that detachably holds the hand of the umbrella, and the vehicle body attachment tube and the hand support tube that are connected to each other and bendable in all directions. A coupling mechanism portion having a universal joint, and the universal joint includes a sphere attached to a rod fixed to an end of the proximal support tube, a holding cylinder that holds the sphere inside, and a sphere The holding mechanism is configured to include a holding piece that moves inside the holding cylinder so as to be able to contact and disengage.The connection mechanism portion including the universal joint includes a tightening ring and a connecting rod, and the tightening ring is attached to the holding cylinder. Engage It has a threaded portion formed on the inner surface, and further has a threaded portion formed on the outer peripheral surface, and is inserted into the inside from the other end of the tightening ring and screwed. At the inner edge of the one end opening of the holding cylinder, it is radially inward to prevent the sphere held inside from coming out of the one end opening. An overhanging locking portion is formed, the pressing piece is disposed on the end of the connecting rod, and the connecting rod relatively moves toward the sphere in the holding cylinder by rotation of the clamping ring. The universal joint is bent in an arbitrary direction by the pressing piece coming into contact with the spherical body and pressing the spherical body against the engaging portion formed at the one end opening of the holding cylinder to suppress the movement thereof. Firmly It was, and is to release.

In one embodiment of the umbrella support for mounting a vehicle body according to the present invention, the hand support is a hollow in which the upper end as one end is open and the rod of the universal joint is fixed to the lower end as the other end. The hollow pipe is provided with a hand receiving portion extending radially outwardly on the outer peripheral surface of the hollow pipe, and the hand receiving portion has a surface facing the upper end side of the hollow pipe with a curved portion at the hand. An opening is formed in the hollow pipe from the base part of the hand receiving part toward the upper end side of the hollow pipe-shaped member, and the tip of the hand from the upper end of the hollow pipe to the inside thereof It is taken out from the opening while inserting, and the curved portion of the hand is placed on and supported by the hand receiving part .

  According to the umbrella support for mounting the vehicle body of the present invention, the handle support that detachably holds the hand of the umbrella is connected to the attachment main body via the connection mechanism portion having a universal joint. Because, for example, it is only firmly attached to the bicycle column, there are few pivots that connect the components to each other. The connecting part of the door does not loosen. As a result, the umbrella support for mounting the vehicle body is extremely durable and inexpensive, and can be obtained with a higher level of safety. Therefore, the umbrella support can be used with confidence on a bicycle.

  Further, in the umbrella support for mounting the vehicle body according to the present invention, the umbrella support for supporting the umbrella can be freely bent by the coupling mechanism portion having a universal joint with respect to the fixture body fixed to the vehicle body such as a bicycle. In addition, since the universal joint is configured to suppress and release the rotation of the sphere by raising and lowering the holding piece by the rotation of the tightening ring, loosening due to vibration hardly occurs. Furthermore, since a universal joint is used as a mechanism for tilting the umbrella support, the umbrella support can be tilted in all directions. For this reason, the structure is simple because a plurality of pivot parts are not used unlike the conventional support, and the durability and safety are remarkably improved accordingly.

  Furthermore, according to the umbrella support for mounting the vehicle body of the present invention, the hand support is formed of a hollow pipe, and a hand receiving portion extending radially outward is provided on the outer peripheral surface of the hollow pipe. An opening is formed in the hollow pipe from the base portion of the hand receiving portion toward the upper end side of the hollow pipe-shaped member, and the surface of the hand receiving portion facing the upper end side of the hollow pipe has a curved portion at hand. Since it is formed in a concave curved surface to be placed, even a commonly used umbrella (an umbrella whose hand is bent in a U shape) can be firmly held without wobbling with respect to the hand support.

  Hereinafter, an umbrella support for mounting a vehicle body (hereinafter simply referred to as “umbrella support”) according to the present invention will be described in more detail with reference to the accompanying drawings showing preferred embodiments thereof. FIG. 1 is an exploded perspective view showing an umbrella support 10 according to a preferred embodiment of the present invention, and FIG. 2 is an umbrella shown in a state where the components shown in FIG. 1 are assembled and the universal joint can be bent freely. 3 is a cross-sectional view of the umbrella support 10 shown in a state where the universal joint is fixed, and FIG. 4 is a cross-sectional view of the umbrella support 10 in a state where the universal joint is bent and fixed. FIG. 5 is a schematic explanatory view of use showing a state in which the umbrella support 10 is attached to a bicycle and used.

  As shown in FIG. 5, the umbrella support 10 includes a hand support tube 11 that is a hand support body that detachably holds a hand 41 of the umbrella 40 and a head tube (post) of a frame F that is a vehicle body of the bicycle B. A connecting mechanism having a vehicle body mounting tube 15 as a mounting body detachably connectable to the HP, a hand support tube 11 and the vehicle body mounting tube 15, and a universal joint 18 that can be bent in all directions. 25. As shown in FIGS. 1 to 4, the hand support tube 11 is composed of a hollow pipe having a predetermined length, and an upper end 11 a that is one end thereof is opened, and a lower end 11 b that is the other end is closed by a bottom plate 12. . A strip-shaped hand receiving portion 13 extending radially outward is provided on the outer peripheral surface of the hand supporting tube 11, and the surface of the hand receiving portion 13 facing the upper end 11a of the hollow pipe is shown in FIGS. It is bent so that it may become the concave curved surface 13a on which the curved part 41a which is the hand 41 of the umbrella 40 is put as shown in FIG. An opening 14 is formed on the outer peripheral surface of the hand support tube 11 from the base 13b of the hand receiving portion 13 toward the upper end 11a of the hollow pipe. The hand receiving portion 13 can be easily formed by cutting and raising the outer peripheral wall of the hand supporting tube 11, and the opening 14 can be formed at the same time by this method.

  On the other hand, the vehicle body attachment tube 15 is also formed of a hollow pipe having a predetermined length, and the inner diameter thereof is slightly larger than the outer diameter of the proximal support tube 11 so that the proximal support tube 11 can be accommodated therein. As shown in FIG. 5, the vehicle body attachment tube 15 is a head tube (a portion for holding a stem to which a handle is attached) of a frame F constituting a vehicle body of a bicycle B using a U-bolt (including a washer and a bolt) 42 and the like. ) Removably connected to HP or the like. At that time, a notch groove (not shown) or the like that can be engaged so that the U-bolt does not slide in the length direction of the peripheral surface of the vehicle body mounting tube 15 is formed at an appropriate position on the peripheral surface of the vehicle body mounting tube 15. It is preferable to keep it. Further, as shown in FIG. 1, a slot 16 is formed in the vehicle body attachment pipe 15 in the longitudinal direction. Further, a relatively wide cut groove 17 from the open upper end 15a to the lower end 15b has a predetermined length. Is formed. The cut groove 17 is formed to have a width slightly larger than the width dimension of the hand receiving portion 13 because it becomes a passage through which the hand receiving portion 13 of the hand supporting tube 11 described above enters and exits.

  The universal joint 18 of the coupling mechanism portion 25 includes a conical rod 19 having one end fixed to the bottom plate 12 fixed to the lower end 11b to close the lower end 11b of the proximal support tube 11, and the other end of the rod 19 The sphere 20 attached to the sphere 20, a holding cylinder 21 that holds the sphere 20 inside, and a pressing piece 22 that moves inside the holding cylinder 21 so as to be able to contact and detach from the sphere 20. As is clear from the cross-sectional view shown in FIG. 2, a claw-like locking portion 23 projecting radially inward is formed on the inner edge portion of the upper end opening of the holding cylinder 21. The inner diameter is smaller than the diameter of the sphere 20. Therefore, when the sphere 20 held in the holding cylinder 21 tries to come out from the upper end opening of the holding cylinder 21, the spherical portion of the sphere 20 abuts on the locking portion 23 and cannot come out. The locking portion 23 may be formed around the entire inner edge of the upper end opening of the holding cylinder 21 or may be formed in pieces in the circumferential direction. Further, a flange 24 (see FIGS. 2 to 4) is formed on the outer peripheral portion of the lower end opening of the holding cylinder 21. The flange 24 may also be formed on the entire outer periphery of the lower end opening, or may be formed in pieces in the circumferential direction.

  The connecting mechanism portion 25 including such a universal joint 18 further includes a tightening ring 26 and a connecting rod 29. The tightening ring 26 includes a flange 27 formed integrally with the inner peripheral edge portion of the one end portion 26a, and a screw portion 28 is formed on the inner peripheral surface thereof. The inner diameter of the tightening ring 26 is larger than the outer diameter of the flange 24 formed on the outer peripheral portion of the lower end opening of the holding cylinder 21, and the inner diameter of the flange 27 formed on the inner peripheral portion of the one end portion 26a is maintained. It is smaller than the outer diameter of the flange 24 formed on the cylinder 21 and slightly larger than the outer diameter of the main body portion of the holding cylinder 21. As a result, the upper end of the holding cylinder 21 and the other end portion 26b of the tightening ring 26 face each other, the holding cylinder 21 is inserted from the other end portion 26b side of the outer tightening ring 26, and both flanges 24 and 27 are axially moved. When engaged, the tightening ring 26 can rotate with respect to the holding cylinder 21, but does not come out of the holding cylinder 21 in the axial direction in which the flanges 24 and 27 are engaged. When the holding cylinder 21 and the tightening ring 26 are actually assembled, the conical rod 19 is held by the holding cylinder 21 before being fixed to the bottom plate 12 attached to the other end of the proximal support tube 11. The spherical rod 20 and the conical rod 19 attached thereto are passed through the tightening ring 26 from the opening of the other end portion 26b to the one end portion 26a side, and the conical rod protruding from the one end portion 26a of the tightening ring 26 is provided. One end of 19 is assembled to the bottom plate 12 by welding.

  The connecting rod 29 has an outer tube 30 with a short outer diameter that can be slidably fitted in the vehicle body mounting tube 15, and is provided concentrically with the outer tube 30 inside thereof, and has an outer diameter smaller than the outer tube 30. The screw cylinder 31 is formed. The threaded cylinder 31 protrudes axially from one end opening of the outer tube 30, and a male threaded part 32 that can be screwed into a female threaded part 28 formed on the inner peripheral surface of the tightening ring 26 is provided on the outer peripheral surface thereof. Is formed. Screw holes 30a are formed at appropriate positions on the peripheral surface of the outer tube 30 in the connecting rod 29. When the connecting rod 29 is housed inside the vehicle body mounting tube 15 which is a hollow pipe, it is formed in the vehicle body mounting tube 15. The butterfly bolt 33 for tightening inserted through the slot 16 is screwed, and the connecting rod 29 is fixed to this at a predetermined position in the vehicle body mounting tube 15.

  The holding piece 22 has a convex shape in a longitudinal section formed by a circular bottom plate 22a and a contact cylinder 22b standing at the center of the surface, and a recess 22c is formed on the upper surface of the contact cylinder 22b. The outer diameter of the contact cylinder 22 b is smaller than the inner diameter of the holding cylinder 21, and therefore, the contact cylinder 22 b can enter from the lower end opening of the holding cylinder 21. The depression 22c formed on the upper surface of the contact cylinder 22b is formed in a curved surface shape that matches a part of the spherical body 20 constituting the universal joint 18, that is, a spherical surface portion. Further, the outer diameter of the circular bottom plate 22 a is slightly smaller than the diameter of the screw cylinder 31 in the connecting rod 29. The presser piece 22 is arranged such that its bottom plate 22a is placed on the upper end portion of the screw cylinder 31 in the connecting rod 29. Therefore, when the tightening ring 26 is screwed to the screw cylinder 31 of the connecting rod 29, the presser piece 22 is tightened. It will be located inside the ring 26. Further, the holding piece 22 is formed with a thin air vent passage that penetrates the center portion in the axial direction.

  Next, the case where the umbrella support 10 is used while attached to a bicycle will be described. Before attaching the umbrella support 10 to the bicycle B, the umbrella support 10 is assembled in advance. As an assembling procedure, first, the connecting rod 29 is inserted into the hollow body mounting tube 15 and the butterfly is inserted from the outside of the body mounting tube 15 through the slot 16 at a position where the screw cylinder 31 protrudes from the upper end. The mold bolt 33 is screwed into the screw hole 31a formed in the outer tube 30 of the connecting rod 29 and fixed. Next, the holding piece 22 is put on the upper end of the screw cylinder 31 in the connecting rod 29, and the tightening ring 26 of the connecting mechanism portion 25 attached so as to be suspended from the bottom plate 12 closing the lower end of the proximal support tube 11 is screwed. The presser piece 22 is housed in the tightening ring 26 by being screwed so as to cover the cylinder 31. At this time, it is preferable to keep the proximal support pipe 11 and the vehicle body attachment pipe 15 in a straight line, that is, in a state where both are not bent at the universal joint 18. FIG. 2 shows this state.

  Since the tightening ring 26 can rotate with respect to the holding cylinder 21 but is engaged in the axial direction, when the tightening ring 26 is further rotated and screwed into the screw cylinder 31, it is put on the upper end together with the connecting rod 29. The holding piece 22 is moved in the direction of the sphere 20 relatively. As a result, the contact cylinder 22b of the pressing piece 22 enters the holding cylinder 21 as shown in FIG. 3, and the sphere 20 is seated (contacted) in the recess 22c on the upper surface thereof. Since the holding cylinder 21 is formed with an air vent passage penetrating in the axial direction at the center thereof as described above, the negative pressure generated in the depression 22c when the sphere 20 is seated in the depression 22c or when it is separated from the depression. It is not affected by positive pressure. Since the spherical body 20 is prevented from coming off by a claw-like locking portion 23 formed at the inner edge of the upper end opening of the holding cylinder 21, when the tightening ring 26 is further rotated in the tightening direction, the holding piece 22 The spherical body 20 is strongly sandwiched between the recess 22c of the contact cylinder 22b and the locking portion 23 of the holding cylinder 21. As a result, since the spherical body 20 cannot be rotated, the universal joint 18 is fixed, and the hand support pipe 11 inclination angle with respect to the vehicle body attachment pipe 15 is maintained.

  In this state, the vehicle body mounting pipe 15 is fixed to the head pipe HP of the frame F of the bicycle B with a U bolt or the like (FIG. 5). Next, the umbrella 40 is attached to the hand support tube 11. This method of attachment will be explained. Since the hand 41 of the general umbrella 40 is curved as shown in FIG. 5, its tip is inserted from one end opening 11a of the hand support tube 11 made of a hollow pipe. The curved portion 41a of the hand 41 is placed on the hand receiving portion 13 while turning the umbrella so as to come out from the opening 14, and the middle rod (shaft) of the umbrella 41 extends in the extending direction of the hand support tube 11. . Thereafter, the hand 41 of the umbrella 40 is tied to the hand support tube 11 using an appropriate fastener such as a tightening band, and is fixed to the hand support tube 11 so that the umbrella 40 does not wobble.

  Next, the fastening ring 26 is slightly loosened to release the fixing of the universal joint 18, and the hand support pipe 11 is held by hand and tilted in a desired direction as shown in FIG. Rotates in the holding cylinder 21 to incline the proximal support tube 11 with respect to the vehicle body mounting tube 15. When the umbrella 40 is moved to the desired position by inclining the hand support tube 11 as described above, when the tightening ring 26 is tightened again, as described above, the depression 22c of the contact tube 22b and the holding tube in the holding piece 22 Since the locking portion 23 of 21 holds the sphere 20 strongly, the universal joint 18 is fixed, and the umbrella 40 is stably held at that position.

  When the umbrella 40 is not required, the umbrella 40 is removed from the hand support tube 11 in the reverse order of the above-described order of attaching the umbrella. In this case, the hand support tube 11 extends upward from one end 15a of the vehicle body attachment tube 15 and interferes with the operation of the bicycle B. Therefore, the tightening ring 26 is loosened, and the hand support tube 11 is removed from the vehicle body attachment tube 15. Make a posture that extends straight up. Next, when the butterfly bolt 33 fixing the vehicle body mounting tube 15 and the connecting rod 29 is loosened and the connecting rod 29 is slid and housed in the vehicle body mounting tube 15, the connecting mechanism portion 25 of the connecting rod 29 is interposed. Most of the connected hand support tube 11 enters the vehicle body attachment tube 15 and is stored. At this time, the hand receiving portion 13 extending outward from the peripheral surface of the hand supporting tube 11 enters the cut groove 17 of the vehicle body mounting tube 15, so that this hand receiving portion 13 is the vehicle body mounting tube 15 of the hand supporting tube 11. There is no hindrance to storage inside.

  The description of the method of using the umbrella support 10 according to the above-described embodiment is for the case where the umbrella support 10 is attached to the frame F of the bicycle B. However, the umbrella support 10 is not used only for bicycles. It can be attached to a frame (appropriate bar-shaped part) such as to protect infants in a stroller and those who push it from rain and sunlight. Further, in the umbrella support 10 of the above-described embodiment, the hand support pipe 11 made of a hollow pipe is used as the hand support, but in the present invention, the pipe is not limited to the hollow pipe, and the pipe is half in the axial direction. It is also possible to use a member having a shape that is divided into two. Similarly, the attachment body uses the vehicle body attachment pipe 15 formed of a cylindrical hollow pipe, but a pipe having a cross section other than a circular shape can be used.

  As described above, according to the umbrella support for mounting a vehicle body of the present invention, not only a general umbrella with a curved hand can be mounted on a vehicle body such as a bicycle, but also the mounting body is attached to the frame F of the bicycle B. Even when the head tube HP is fixed with a U-bolt or the like, the posture can be corrected so that the umbrella is positioned above the driver's head. Further, in this umbrella mounting tool for mounting the vehicle body, as is clear from FIG. 1, the pivot part is not used for connecting the parts, so the umbrella collapses suddenly due to severe vibration received from the road surface while the bicycle B is running. There is no such thing. As described above, the umbrella support for mounting the vehicle body according to the present invention is extremely durable and inexpensive in terms of cost, and also provides higher safety. Can do.
