Description

  The present invention relates to a suspended bicycle suitable for use by those who aim to recover or improve physical function.

  There are various devices used for the purpose of rehabilitation or training, and in particular, a bicycle-like device is used to improve leg strength. In many cases, a bicycle structure having a seat, a handle, and a pedal mechanism is erected on a floor surface, and a rider strides over the seat by gripping the handle and strides the pedal mechanism. In this case, a large number of bicycle structures are installed. Therefore, space is taken for this purpose, which hinders the traffic of people and interferes with the installation of other devices. In addition, the pedal mechanism is monotonous simply by stroking the pedal mechanism, and the passenger may be interested and not rehab or training.

  Therefore, if the pedal mechanism is moved forward (reversed) like an actual bicycle, it will be interesting. However, if the occupant is a rehabilitation person, the balance is not sufficient and there is a risk of falling. For this reason, a bicycle that does not fall is desired, but in order to prevent a bicycle that is propelled on the floor from falling, a complicated fall prevention mechanism is required, which increases costs and impairs the original propulsive force. Sometimes. In such a case, there is no danger of falling if the bicycle is suspended from a rail or the like stretched upward. In addition, since the rail is on the upper side, it is possible to effectively use the lower space without hindering human movement or the like.

For this reason, a suspended bicycle can be considered. However, the applicant has previously proposed this as Patent Document 1 below. However, since the preceding example is installed in a short space such as a mine or a closed waterway, it is often impossible to secure a sufficient space between the ceiling and the rail. Therefore, the drive roller having a certain diameter has to be applied to the lower surface of the rail, the transmission mechanism becomes complicated, and there is a situation in which it cannot slip and propel. Furthermore, since this bicycle is intended to be removed from the rails on the way, it has to have a complicated structure.
JP 2002-178912 A

  The purpose of the present invention is to use such a suspended bicycle exclusively for rehabilitation and the like, and for this purpose, the structure is further simplified to reduce the cost and the functionality is further enhanced. It is.

  Under the above-described problems, the present invention provides a rail constructed on the ground or floor, a drive roller that rolls on the top surface of the rail, and a swingable back and forth with a bracket from the drive roller. A suspended frame, a bicycle structure including a seat, a handle, and a pedal mechanism provided in front of the driving roller of the frame; a transmission structure that transmits the driving force generated on the pedal shaft of the pedal mechanism to the driving roller; The present invention provides a suspended bicycle characterized by comprising an idler roller that is provided at a position behind the drive roller and rolls in contact with the lower surface of the rail.

  Further, according to the present invention, there is provided a belt, a wire pulley, a chain in which the transmission structure according to claim 2 is extended from the lower side of the occupant seated on the seat to the drive roller from behind to the driving roller. -Means that are sprockets, means according to claim 3, means in which rubber is lined on one or both of the driving roller and idler roller, and the rail according to claim 4 is constructed outdoors. , Providing a means for the rain or sun protection roof of a predetermined width to be attached to the rail over the entire line or partially.

  According to the first aspect of the present invention, since the driving roller rolls on the upper surface of the rail, it does not slip due to the weight of the device or the weight of the passenger. Further, the transmission mechanism from the pedal mechanism to the drive roller is as simple as a normal bicycle. Furthermore, since the rail is sandwiched from above and below by the idler roller that rolls on the lower surface of the rail, not to be overturned, shaking and derailment do not occur. In this respect, the passenger can perform rehabilitation and the like in a manner similar to that of a bicycle, i.e., in an interesting manner, and the effect is high.

  In addition, since it can be installed outdoors or indoors, the space below the rail is vacant, and does not interfere with traffic and traffic, and can be applied to other purposes. In addition, since a rail is made into a loop type with a long route, and a plurality of bicycle structures can be suspended on this rail, many people can be rehabilitated at the same time. Further, according to the means of claim 2, the passenger is not exposed to dangerous eyes by the transmission structure, and according to the means of claim 3, the traveling of the bicycle structure is soft and quiet. Furthermore, according to the means of claim 4, the bicycle structure can travel without being exposed to rain or the sun. In this case, if the roof is attached over the whole line, the lower part can be used as a passage, and if it is partially attached, it can be used as a raindrop.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a side view of a suspended bicycle (hereinafter referred to as a bicycle) according to the present invention, FIG. 2 is a view taken along the line AA in FIG. 1, FIG. 3 is a view taken along the line BB, and FIG. As shown in the arrow C, in order to install this bicycle, the rail 1 is first constructed. A square pipe or the like is suitable for the rail 1, and if it is indoors, it is suspended from the ceiling 2 by a suspension member 3, and if it is outdoor, it is erected by a column (not shown). A drive roller 4 is applied to the upper surface of the rail 1, and the drive shaft 5 of the drive roller 4 is rotatably inserted into a cantilever bracket 6 on the side where the suspension member 3 is not provided.

  The reason why the bracket 6 is cantilevered is that the suspension member 3 and the bracket 6 interfere with each other when the drive roller 4 passes the suspension member 3, and this is avoided. The drive roller 4 is formed by forming flange portions 4b sandwiching the rail 1 from both sides of the body portion 4a that rolls on the upper surface of the rail 1, thereby preventing derailment. Further, a rubber 7 is lined on the outer periphery of the body portion 4a, and the frictional force with the rail 1 is strengthened and the shock absorbing property and quietness are ensured.

  The lower end of the bracket 6 is bent to the suspension member 3 side, and a frame 8 made of a pipe or the like extends from the center (center of the driving roller 4) into a substantially U shape in a side view. The frame 8 is categorized into a downward extending portion 8a, a forward extending portion 8b, and an upward extending portion 8c from the lower side. The front extending portion 8b is provided with a seat 9 on which a passenger sits, and the lower extending portion 8a has a passenger from above. A headrest 10 for leaning the head and a backrest 11 for leaning the back are attached. Further, the upward extending portion 8c is provided with a pedal mechanism 15 in which an arm 13 is formed in a crank shape at both ends of the pedal shaft 12 and a pedal 14 is attached to the tip thereof, and a handle 16, an illumination lamp 17, A scissor 18 is attached. The seat 9, the pedal mechanism 15, the handle 16, and the like constitute a bicycle structure 19.

  Further, the auxiliary frame 20 is extended rearward from the downward extending portion 8a, the bracket 21 is extended from the rear end thereof, and the idler roller 22 is attached thereto so that the idler roller 22 contacts the lower surface of the rail 1. Yes. In this case, since the bracket 21 is provided below the rail 1, it can be cantilevered on the side of the suspension member 3, so that the left and right balance with the bracket 6 of the driving roller 4 can be achieved. become.

  When the passenger rides on the bicycle structure 19, the center of gravity of the frame 8 shifts further forward from the driving roller 4 from its form, and the frame 8 tries to rotate clockwise in FIG. 1 about the driving shaft 4. The roller 22 is in contact with the rail 1, so that the regulation of the rotation and the contact with the rail 1 are ensured. As a result, the driving roller 4 and the idle roller 22 sandwich the rail 1 from above and below, so that the posture of the frame 8 is kept stable. If the idle roller 22 is the same as the drive roller 4, the idle roller 22 can be shared and the cost can be reduced.

  Although the pedal mechanism 15 is shown in FIG. 4, when the pedal 14 is stroked, a driving force is generated on the pedal shaft 12, and this driving force is transmitted to the driving roller 4. Specifically, the pedal shaft 12 and the driving roller 4 are connected by a transmission structure 23 including a belt, a wire pulley, a chain sprocket, or the like. As the transmission structure 23 in this case, a timing belt, a V-belt, a chain, or the like that hardly causes a slip or the like is preferable, and among them, a timing belt is most suitable. In this case, since the driving roller 4 is applied to the upper surface of the rail 1, the rotation direction of the pedal shaft 12 and the driving roller 4 coincide with each other as in a normal bicycle, and there is an advantage that the transmission mechanism is simplified. .

  In addition, an idle roller 24 that appropriately changes the direction of the transmission structure 23 and adjusts the tension is appropriately provided at an appropriate position of the frame 8 between the pedal shaft 12 and the drive roller 4. For this reason, some idle rollers 24 can be changed so that their positions can be returned to their original positions by springs or the like. Further, the above-described transmission structure 23 pays attention to safety through the lower side and the rear side of the frame 8 so as not to touch the passenger. In addition, it is suitable for safety to provide a thing such as a gutter 25 that shields from the rail 1 on the head of the passenger.

  Next, a method of using the bicycle having the above configuration will be described. When the passenger sits on the seat 8 and strokes the pedal 12, the drive roller 4 rotates and the whole moves forward. In this case, in general, it is suitable that the pedal mechanism 15 and the drive roller 4 are directly connected so that the pedal 14 moves forward when the pedal 14 is stepped forward and reverses when the pedal 14 is stepped backward (the brake works when stopped). ). Of course, like a normal bicycle, if a one-way clutch (not shown) is incorporated in the pedal mechanism 15, the vehicle moves forward only and moves forward by inertia even when the pedal 12 is stopped. Further, if necessary, it is possible to incorporate a brake into the drive roller 4 and apply the brake by operating a lever attached to the handle 16 or the like (not shown).

  As a result, the passenger can rehabilitate safely and comfortably. At this time, unlike the fixed type bicycle, the entire body moves forward, so that it becomes exciting and enters rehabilitation. At this time, if the route of the rail 1 is made long, a number of bicycle structures 19 can be suspended on one rail 1, and many people can use it at once. In addition, the lower part of the rail 1 is an open space, which does not interfere with walking and can be used for other purposes. In this respect, this bicycle can also be applied to a moving means for handicapped persons (same as healthy persons). In particular, it is possible to move between houses in the air.

  In addition, when the rail 1 is installed outdoors, it is also possible to attach a roof with a predetermined width for rain protection and awning on the rail 1 as a foundation. Therefore, it can move without being exposed to rain or the sun. In this case, the roof may extend over the entire line or may be partial. The former can be used for the passage, and the latter can be used for temporary rain.

It is a side view of a suspended bicycle showing an example of the present invention. It is an AA arrow line view of FIG. It is a BB arrow line view of FIG. It is CC arrow line view of FIG.
