DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a saddle cover for detachably attaching to a saddle such as a bicycle or a motorcycle to protect water or dust caused by rain, snow or frost from attaching to clothes. In particular, the take-up mechanism mounted in the storage case is attached to the frame near the saddle via the attachment, and the saddle cover is pulled out as needed and used, and after use, the spring pulls the spring. The present invention relates to a saddle cover device that can be automatically rewound into a storage case.

[0002]

2. Description of the Related Art Various proposals have been made for a saddle cover device of this kind, including, for example, the one disclosed in Japanese Utility Model Laid-Open No. 55-163288. In these saddle cover devices, a band-shaped sheet formed at the end with a saddle cover portion to be attached to the saddle, and the band-shaped sheet is mounted in a storage case in which an entrance of the band-shaped sheet is perforated so that the band-shaped sheet can be pulled out. And a frame mounting portion for attaching the winding mechanism to a frame such as a bicycle near the saddle. The winding mechanism is connected to a base end of the belt-shaped sheet. A take-up roll rotatably mounted in the storage case; and a spring member that applies a rotational torque to the take-up roll and urges the band-shaped sheet to be constantly taken up in a winding direction. Has a basic structure provided with a locking member for preventing the strip-shaped sheet from being pulled out and excessively entangled.

In the above saddle cover device, the saddle cover portion of the belt-shaped sheet is formed in a bag shape adapted to the shape of the saddle in advance, and the saddle cover portion is folded into a storage case in a width substantially equal to the width of the saddle. Since it is spread out when it is attached to the saddle, it is used so that the width of the doorway formed in the storage case and the width of the winding roll for winding the belt-like sheet are substantially equal to the width of the saddle. The locking device is fixedly attached to the end of the saddle cover portion of the belt-shaped sheet. In use, the locking device is gripped and the belt-shaped sheet is drawn out to a predetermined length. Is spread and attached to the saddle. Further, a ring-shaped attachment is fixed to the outer peripheral surface of the storage case on the side opposite to the entrance, and the storage case is arranged such that the storage case is orthogonal to the vertical frame supporting the saddle on the rear side. The belt-shaped sheet pulled out of the storage case is attached from behind the saddle. In addition, a squeeze roller is provided at the entrance to reduce water droplets attached to the belt-like sheet from entering the storage case.

[0004]

However, in the case of the conventional saddle cover device having the above configuration, there are some problems that need to be solved as follows. First, if the saddle cover portion is formed in a bag shape adapted to the shape of the saddle in advance, the saddle cover portion can be attached only from either the front side or the rear side of the saddle,
The position of the frame on which the device is mounted is also limited.
In addition, since each piece is processed into a bag shape at the time of manufacturing, the structure is not suitable for reducing the cost by mass production. In addition, when the sheet is folded, an uneven surface is generated, so that the winding of the belt-shaped sheet is not performed smoothly, or the attached water droplets are not drained well. Next, if the width of the saddle cover portion of the belt-shaped sheet, the entrance of the storage case, and the width of the take-up roll are substantially equal to the width of the saddle in the folded state, the storage case needs to have a wider width than that. Since the winding mechanism including the case becomes large, for example, if it is used by attaching it to the front of a horizontal frame or a vertical frame located in front of the saddle, it becomes a hindrance when driving, and the conventional device exclusively supports the saddle vertically. It was a structure to be attached to a frame.

[0005] Next, if the locking device is fixedly attached to the tip of the saddle cover, the locking device must be parallel to the entrance of the storage case when the belt-like sheet is pulled out. There is also a risk that it will not be able to be smoothly pulled out. Further, this locking device does not have a function as a hook for locking and holding the periphery of the saddle, and a structure in which the saddle cover portion is spread, directly attached to the saddle, and locked and held only at the edge of the cover. For this reason, it is necessary to perform a troublesome work of spreading the saddle cover with the other hand and attaching the saddle to the saddle while pulling the belt-like sheet against the traction force of the spring with one hand holding the locking tool. At the same time, if only the edge of the saddle cover is locked, the holding may be unreliable and may come off.

[0006] Next, in a structure in which the attachment fixed to the storage case is attached to the vertical frame immediately below the saddle, depending on the type of vehicle, the cushion spring of the saddle cannot be attached, or if the attachment is attached, the height of the saddle is adjusted. As a result, the width of the device hinders the operation of the device as described above, so that the device cannot be mounted on the front surface of the horizontal frame or the vertical frame located in front of the saddle.

Next, the intrusion of water droplets into the storage case is reduced by a squeeze roller provided at the entrance of the belt-shaped sheet, but it cannot be completely prevented, and neither waterproof nor drainage means is provided. There is a possibility that the spring member is corroded by the water droplets that sequentially enter and stay in the case, and the traction force is reduced to make the case unusable. Therefore, in the present invention,
It is an object of the present invention to provide a saddle cover device for solving the above-described problems of the related art.

[0008]

When the take-up roll 36 is mounted on the case body 30, the end of the support shaft 32 is inserted through the through hole 37 a of the partition plate 37 when the take-up roll 36 is mounted on the case main body 30. The insertion piece 38b is fitted and locked in the notch groove 32a.

A belt-shaped sheet 39 having a locking member attached to the distal end and a base end connected via rivets or other fixing means is wound around the outer diameter portion of the winding roll 36. The belt-shaped sheet 39 has a fixed width in which a lead portion 39a is formed on a base end side and a saddle cover portion 39b is formed on a distal end side, and is made of, for example, a waterproof fabric such as polyester. The lead portion 39a has at least the saddle cover portion 39.
b is formed of a single piece of cloth having a predetermined length necessary for attaching the saddle to the saddle and having a width sufficiently smaller (about half) than the lateral width of the saddle, and a saddle cover portion 39b is sewn to the end. . The saddle cover portion 39b is provided with a lead portion 39a along the longitudinal direction of the cloth which is sufficiently wider than the width of the saddle.
A plurality of folds are provided in the same width as above, and multiple folds are formed from the folds to form a vertical cross section along the width direction in a zigzag shape. The other ends are connected to each other by attaching a locking tool described later, so that the width dimension can be expanded or reduced. As a result, the saddle cover 39b is normally formed in a multiple band shape having the same width as the lead portion 39a, and is formed into a bag shape that can be attached to the saddle when each superimposed sheet piece is stretched.

As shown in detail in FIG. 5, the locking member mounted on the front end of the band-shaped sheet 39 has an arcuate inner surface around the outer periphery of a holding piece 41a having a U-shaped groove in cross section. A locking plate 41 protruding from the flange portion 41b and a locking hook 40 attached to the holding piece 41a of the locking plate 41 such that the tip thereof is rotatably fitted. Each part is made of a hard synthetic resin material. Locking plate 41

9b is connected via a fastening member such as a rivet 43 at the other end, and a flange portion 41b protruding outward is provided at the entrance 3 of the storage case when the belt-shaped sheet 39 is wound up.
Oa is formed in such a size that it is locked to the opening edge in a manner to close Oa.

A winding mechanism B is provided inside the case body 30.
The above-mentioned constituent members are accommodated, and a cap 42 is mounted on the opening side of the case main body 30, and the case main body 30 and the cap 42 cooperate to form a storage case. The cap 42 is formed in a frustoconical cylindrical body whose inner end is fitted and attached to the opening of the case body 30 and is tapered outward in a tapered shape, and has an inner bottom portion of the frustoconical cylindrical body. A bearing cylinder 42a having a bearing hole 42b formed in the shaft center is projected from the shaft. A ring-shaped pressing plate 42c is formed at the tip of the bearing cylinder 42a, and these parts are integrally formed of a hard synthetic resin material. Is configured.

When the cap 42 is fitted and attached to the opening of the case body 30, the presser plate 42 c is inserted into the inner diameter portion of the take-up roll 36 in a tight fit, and one side is supported by the partition plate 37. The other end of the support shaft 32, which supports the other side surface of the spring 38 and engages with the insertion piece 38b of the leaf spring 38 in the notch groove 32a, is attached to the bearing hole 4 of the bearing cylinder 42a.
2b. If necessary, a packing 4 for sealing is provided on the back surface of the holding plate 42c.
4, the holding plate 42c may be formed separately from the cap 42. Thereby, the winding roll 3
6 is rotatably supported by the support shaft 32 of the case body 30 and the bearing cylinder 42a of the cap 42, and the leaf spring 37 in the take-up roll 36 is stored in a substantially watertight state between the partition plate 37 and the pressing plate 42c. Is done.

In the above-mentioned winding mechanism B, when the belt-shaped sheet 39 wound on the winding roll 36 is pulled out, the winding roll 36 pivotally supported between the case body 30 and the cap 42 is rotated and The leaf spring 38, on which the fixing piece 38a at the outer peripheral end is locked by the winding roll 36 via the locking piece 37b, is also rotated in conjunction with the rotation. This leaf spring 3
Since the insertion piece 38b at the inner peripheral end is locked to the support shaft 32 via the cutout groove 32a, the winding 8 is tightened by the rotation, and the traction force in the winding direction is gradually increased. Belt sheet 3 pulled out against traction force
When the pull-out force is released, 9 is automatically rewound on the winding roll 36.

In the saddle cover device having the above-described structure, the fixed cylinder 20 of the frame mounting portion A is fitted into desired frames 10 and 12 near the saddle 11 as shown in FIG. 21 is fixed with a set screw 22. This saddle cover device can be used by attaching it to the back of the vertical frame 10 immediately below the saddle 11 in a horizontal state in which the storage case is orthogonal to the conventional device, but a cushion spring or the like hinders the saddle cover device. Even with a type of bicycle that cannot be mounted, (a) in FIG.
As shown in (b), it can be selectively mounted on the vertical frame 10 or the horizontal frame 12 located in front of the saddle 11 for use. That is, since the saddle cover 39b of the band-shaped sheet 39 is always formed as a band that is folded multiple times and is much narrower than the lateral width of the saddle 11, the width of the winding mechanism B including the storage case is significantly larger than that of the conventional structure. Since it is possible to shorten the winding mechanism B, the winding mechanism B is in a horizontal state orthogonal to the frames 10 and 12 and is mounted in front of the saddle 11 so as not to hinder driving. Further, the saddle cover portion 39b is not manufactured in a state in which the saddle cover 39b is kept in a shape suitable for the saddle 11 in advance as in the conventional structure, but is formed into a bag shape suitable for an arbitrary saddle shape when the belt-like body is expanded. Therefore, the saddle cover portion 39b can be attached from either the front or the rear of the saddle 11.

Vertical frame 1 located in front of saddle 11
The saddle cover device mounted on the zero or horizontal frame 12 is used in a horizontal state in which the storage case is orthogonal to the frame as shown by the solid line in (a) and (b) of FIG. As shown by a virtual line, the frame can be kept parallel to the frame. That is, the storage case may always be used in a horizontal state orthogonal to the frames 10 and 12, but the rotation connecting portion 24, which can adjust the angle between the frame mounting portion A and the winding mechanism portion B at 90-degree intervals, may be used. 31
In the case of the configuration provided with the storage case, if the storage case is kept in a horizontal state perpendicular to the frame only when the storage case is used, and the storage case is normally rotated in parallel with the frames 10 and 12, the driving case is further obstructed. It can be in a state that does not become.

When attaching the saddle cover 39b, the locking hook 40 exposed outside the case body 30 is used.
Is pulled out while holding the case body 30.
The belt-shaped sheet 39 wound around the outer diameter portion while the inner take-up roll 36 rotates is passed through the entrance 30a as shown in FIG.
As shown in the figure. When the belt-shaped sheet 39 is pulled out, a traction force is applied in the winding direction by the leaf spring 38 compressed by the rotation of the winding roll 36, and the belt-shaped sheet 39 is pulled against the traction force. If the locking hook 40 is pulled sufficiently from the front of the saddle 11 to the rear side to lock the locking hook 40 at an arbitrary locking portion immediately below the saddle 11 (for example, a connecting portion of left and right cushion springs),
The saddle cover 39b of the tensioned band-shaped sheet 39 is stretched on the upper surface of the saddle 11 in a state of the band-shaped sheet. Therefore, when the widthwise ends of the multiply folded saddle cover portion 39b are gripped with both hands and opened right and left, the longitudinal end portions are fixed, so that the middle portion is most enlarged to form a substantially elliptical shape. Then, when both ends in the width direction of the saddle cover portion 39b are wound around the bottom side of the saddle 11, the both hands are released, and the saddle cover portion 39b is moved to the state shown in FIG. As shown in the figure, the shape is kept in a bag shape suitable for the saddle, and FIG.
It is attached to the saddle 11 as shown in (b). The saddle cover portion 39b is attached in advance, for example, in anticipation of the danger of rain when the bicycle is parked outdoors, and prevents the saddle 11 from getting wet with rain, and makes the clothes dirty when riding. Normal use is to avoid such a situation, but there is also a mode in which the saddle 11 is used by being attached to the already wet saddle 11.

When the belt-shaped sheet 39 is to be rewound into the storage case after use, the saddle cover 39b is removed from the saddle 11 by removing the locking hook 40 from the locking position and holding the locking hook 40 by hand. Then, the belt-shaped sheet 39
On the base end side of the winding roll 3, the traction force of the leaf spring 38 applies.
6, the saddle cover portion 39b, which is shaped like a bag at the time of attachment, is restored to a multiply folded band shape, and the gripped hook 40 is released from the hand. Then, the belt-shaped sheet 39 is automatically drawn into the storage case while being wound up by the winding roll 36, and is rewinded when the locking plate 41 abuts on the opening edge while closing the entrance 30 a of the case body 30. Ends.

The locking tool composed of the locking plate 41 and the locking hook 40 may be formed integrally with each other, but the locking hook 40 is rotated with respect to the locking plate 41 as in the embodiment. When the belt-like sheet 39 is attached as possible, operations such as taking in and out of the belt-like sheet 39 and attaching / detaching to / from the saddle 11 can be easily performed. That is, when the rotatable locking hook 40 is gripped, the band-shaped sheet 39 whose tip is fixed to the locking plate 41 swings, so that when the band-shaped sheet 39 is pulled out or rewound, the band-shaped sheet 39 is inserted into the entrance 30a of the case body 30. It is easy to maintain in a state parallel to, and can be smoothly pulled out and rewound without twisting. Further, after the belt-shaped sheet 39 is not pulled back via the locking hook 40, the saddle cover 39b can be attached to the saddle 11 with both hands, so that the locking without the locking hook is possible. The attachment is easier and more reliable than the tool, and when the locking hook 40 is made rotatable, the range of selection of the attachable attaching portions is increased, and the torsion of the band-shaped sheet 39 is corrected when attached. be able to.

In a state where the belt-shaped sheet 39 is automatically drawn into the storage case and the rewinding is completed, the locking plate 41 closes the entrance 30a of the case main body 30 and contacts the opening edge as described above. Since they are in contact with each other, no water droplets enter the storage case through the doorway 30a when the device is not used. Further, water droplets adhere to the band-shaped sheet 39 during use and water droplets enter the storage case through the entrance 30a during winding. However, since the saddle cover 39b is formed in a multiply folded flat band shape, this saddle is formed. The drainage is better than in the case of a conventional structure having a cover portion formed in a bag shape in advance and having irregularities. Further, measures are taken to prevent the performance of the winding mechanism B from being degraded by water droplets entering the storage case. One of the means is to take up the winding roll 36 so that water droplets do not enter and corrode the leaf spring 38 which is a main part of the winding mechanism B.
The partition plate 37 and the holding plate 42 are housed in
It is made substantially sealed by c or the like. As another means, a drain hole is provided at a position that becomes a bottom surface in an attached state so that water droplets do not remain in the storage case,
In this embodiment, a drain hole 30c is formed on the lower surface side of the case body 30 which is a bottom surface when used by being attached to the horizontal frame 12.
Are provided on the side surfaces of the case main body 30 which serve as bottom surfaces when used by being attached to the vertical frame 10.

As is clear from the above embodiments, the saddle cover device according to the present invention can be expected to have the following effects which cannot be obtained by the prior art. In the saddle cover device according to the first aspect, when the saddle cover portion is taken in and out, the sheet material is formed into a narrow band-like body in which the sheet material is folded in multiple layers, and when the sheet material is spread on the saddle, it becomes a bag shape. I have. As a result, the width of the winding mechanism including the storage case can be significantly reduced, so that in the conventional structure, the device mounted on the vertical frame behind the saddle so as not to obstruct the operation is obstructed. It becomes possible to attach it to the vertical or horizontal frame in front of the saddle without using it, and depending on the model, the cushion spring of the saddle can not be installed and it can not be installed, or if it is installed, the height of the saddle can not be adjusted The problem of the conventional structure was solved,
Any position can be selected and mounted on any vehicle type. In addition, since the saddle cover portion is usually formed in a bag shape when it is attached to the saddle with a belt-like body, the saddle cover portion is attached to the saddle like a conventional structure that is formed in a bag shape that matches the shape of the saddle in advance. The direction is not limited, and the saddle can be attached from either the front or rear direction.

Further, in the saddle cover device of the first aspect,
The pulling operation of the band-shaped sheet, the locking hook for locking the leading end side of the band-shaped sheet at a desired position of the vehicle body to hold the drawn state, and the leading end side of the band-shaped sheet are connected, and the band-shaped sheet is wound. And a locking plate for preventing excessive entanglement when the locking device is used.The locking plate is formed with a waterproof / flange portion which abuts the opening edge of the entrance of the storage case and closes the entrance in a watertight manner. ,
The locking hook is capable of swinging and rotating relatively with respect to the short side direction of the band-shaped sheet between the front end side of the band-shaped sheet,
Since the base end is rotatably connected to the locking plate, gripping the locking hook when pulling out or rewinding, the band-like sheet swings and is maintained in a state parallel to the doorway, without twisting. Can be smoothly pulled out and rewound. When the locking hook is locked to the bottom of the saddle, the saddle cover can be spread with both hands and attached to the saddle. In addition to being reliable, when the locking hook is rotated, the range of selection of the locking portions that can be mounted is increased, and the twist of the belt-shaped sheet can be corrected when mounted.

In the saddle cover device according to the second aspect, the locking plate of the locking member holds the leading end side of the band-shaped sheet and has a U-shaped cross section to which the band-shaped sheet is connected via a fastening member. And a flange portion projecting from the holding piece to the outer periphery and forming an arc-shaped inner surface which abuts on the opening edge of the entrance of the storage case. With the extremely simple structure in which the base end side of the locking hook is rotatably attached to the piece, the above-mentioned various excellent effects can be achieved at low cost.

In the saddle cover device according to the third aspect, in the storage case of the winding mechanism, flanges are formed at both ends, and a winding roll on which a belt-shaped sheet is wound around the outer periphery of the flange can be rotated. The take-up roll is housed in a water-tight state, and the spring member that pulls and urges the inside of the take-up roll in a state where both ends are closed is housed in a water-tight state. A drain hole is provided between the storage case and the take-up roll to discharge water droplets that have penetrated to the outside. This is a structure in which performance is unlikely to deteriorate.
