Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing an embodiment of a hand run bicycle according to the present invention, Figure 2 is a cross-sectional view showing a coupling state of the foot member and the foot guide of Figure 1, Figure 3 is a coupling state of the extension member and the projection of Figure 1 The figure which shows.

As shown in FIG. 1, the hand-run bicycle 100 according to the present invention is classified into its components, and the frame 110 and the front wheel 131 and the frame 110 mounted at the front of the frame 110. Rear wheels 132 mounted on the rear of the first handle portion 150, the pedal portion 170, the second handle portion 180 and the connection connecting the first handle portion 150 and the pedal portion 170 An instrument 190 is provided.

The front wheels 131 and the rear wheels 132 are rotatably installed at intervals back and forth on the frame 110, respectively. When the front wheel 131 and the rear wheel 132 is rotated by an external force, it serves to move while supporting the frame 110 on the ground.

The hand run bicycle 100 according to the present invention includes a first handle part 150 connected to the pedal part 170. The first handle part 150 is disposed in the width direction of the bicycle from side to side and has a first handle 154 installed up and down on the first shaft 152 and the first shaft 152 rotatably installed on the frame 110. Equipped. The first handle member 154 is connected to the pedal 176 through a connecting mechanism 190 whose lower portion is described later. The first handle member 154 is preferably rotatably installed from side to side on the first shaft 152 through the third shaft 156 in the form of a pin. This is to allow the front wheel 131 to be steered by rotating the first handle part 150 to the left and right with respect to the third shaft 156. The third shaft 156 is not necessary when the front wheel 131 is to be steered only by the second handle unit 180 described later. When the first handle member 154 is not in use, the upper portion of the first shaft 152 is lifted upwards and then folded downward so as not to interfere with the operation using the second handle portion 180, and then it can be used only when needed. It is desirable to configure so that. In addition, it is convenient for the steering operation that the hand held portion is arranged on the same line as the portion connected to the lower connection mechanism 190.

Between the first handle member 154 and the front wheel 131 is provided with an interlocking means 200 for adjusting the steering angle of the front wheel 131 according to the left and right pivot angle of the first handle member 154, This is explained in more detail later.

The second handle part 180 includes a second shaft 182 and a second handle member 184. The second shaft 182 is disposed up and down, and is installed on the frame 110 so as to rotate in place. The second handle member 184 is provided on the upper end of the second shaft 182 so as to protrude substantially horizontally and from side to side. The second handle part 180 is mainly connected to the front wheel 131 serves to adjust the steering angle of the front wheel 131.

The pedal unit 170 is installed at the center of the rear wheel 132. The pedal unit 170 is for allowing the rider to step on foot to obtain a driving force. The pedal unit 170 is not necessarily installed on the rear wheels 132, and may be installed to be rotated on the frame 110 as in a general bicycle, in which case the power of the pedal is transmitted to the rear wheels 132. Chains and sprockets are needed. Between the shaft 172 and the rear wheels 132 of the pedal unit 170 is installed a ratchet (ratchet) and the like as in a normal bicycle, the power by the rotation of the pedal unit 170 is transmitted to the rear wheels (132). In addition, even if the operation of the pedal unit 170 is stopped while driving, the rotational force of the rear wheel 132 is preferably not to be transmitted to the pedal unit 172 so that the cyclist can rest. More preferably, the rear wheel 132 through which the power of the pedal unit 170 is transmitted is provided with a ratchet mechanism 173 that can switch the direction in which the power of the pedal unit 170 can be transmitted by the lever. It is desirable to be able to choose either forward or reverse. The ratchet mechanism 173 is preferably connected to the first handle portion 150 or the second handle portion 180 to be operated by hand. Since the ratchet mechanism 173 is a well-known technique implemented in a box wrench tool for selecting forward and reverse rotations used when locking or releasing bolts and nuts, detailed description thereof will be omitted.

The pedal unit 170 is pivotally coupled to the shaft 172 coupled to the center of the rear wheel 132 and the L-shaped pedal member 174 and the pedal member 174 connected to both sides of the shaft 172. Pedal 176 is provided. The pedal member 174 is preferably formed at intervals between the pin hole at two members having a hollow portion and a member inserted into the hollow portion, and the length of the pedal member 174 can be adjusted using the pin 174a.

 This pedal unit 170 is for the rider to step on the foot to obtain a driving force. Since the pedal unit 170 is directly installed on the rear wheel 132, a separate power transmission means such as a chain and a chain sprocket is not necessary.

Hand run bicycle 100 according to the present invention is provided with a connection mechanism 190 and the footrest guide 220. The coupling mechanism 190 connects the pedal unit 170 and the first handle member 154 so that the pedal unit 170 performs a circular motion, so that the first handle member 154 is centered on the first shaft 152. It plays a role of pendulum movement back and forth. Conversely, the first handle part 150 may serve to rotate the pedal part 170 by pushing or pulling the first handle part material 154 back and forth. The connection mechanism 190 includes a foot member 192 mounted to the pedal unit 170 to perform a circular motion with the pedal unit 170. Guide member 193 is formed in the scaffold member 192 in the front-rear direction. The guide 193 is assembled to the scaffold guide 220 to guide the movement of the scaffold member 192. Referring to Figure 2, the scaffold member 192 is preferably in the form of a square cross-section of the bottom open form.

The connection mechanism 190 has an extension member 194. The extension member 194 extends toward the scaffold member 192 in a state where the extension member 194 is rotatably connected to the lower side of the first handle member 154. The elongated member 194 is formed with a long hole 195 in the longitudinal direction thereof, that is, in the front-rear direction of the bicycle. This long hole 195 is a portion to which the protrusion 204 provided in the first link member 202 described later is coupled.

In addition, the coupling mechanism 190 has a joint 196. This joint 196 is for connecting the extension member 194 and the scaffold member 192 to each other. The joint 196 has a first joint portion 196a that allows the extension member 194 and the scaffold member 192 to be bent up and down in each other.

Preferably, the joint 196 further has a second joint portion 196b that allows the extension member 194 and the scaffold member 192 to be bent in a horizontal direction with each other. This is because when the first handle member 154 is rotated to the left and right about the third shaft 156, the extension member 194 also rotates to the left and right about the second joint 196b and to steer the front wheel 131. This is to make it possible.

The scaffold guide 220 is installed in the frame 110 in front of the scaffold member 192 so as to rotate in place. One side of the scaffolding guide 220 is coupled to the guide portion 193 of the scaffolding member 192 to support the scaffolding member 192 while moving along the scaffolding member 192 while being rotated during the rotation operation of the scaffolding member 192. Play a role. Referring to Fig. 2, the scaffolding guide 220 preferably has an industrial cross section. This is to allow the rollers 197 installed on both sides of the scaffold member 192 to be inserted and coupled inward from both sides of the scaffold guide 220 of the worker shape so as to receive the guide of the scaffold guide 220. A bearing may be used instead of the roller 192.

As shown in FIG. 1, an extension part 182a extending to one side is formed at a lower side of the second shaft 182, and a first link member 202 is connected to the extension part 182a. The first link member 202 is rotatably connected to the extension portion 182a. Accordingly, the first link member 202 moves left or right as the extension 182a is rotated about the second shaft 182. The second link members 203 are connected to both ends of the first link member 202 so as to be rotatable with each other. The second link members 203 are connected to the front wheels 131, respectively. Accordingly, as the first link member 202 is moved left and right, the second link member 203 adjusts the direction of the front wheel 131 while rotating left or right.

Here, the extension part 182a, the first link member 202 and the second link member 203 adjust the steering angle of the front wheel 131 according to the rotation direction and the rotation angle of the second shaft 182. Since the role of giving, in the present invention it is defined as the second axis linkage.

As shown in FIG. 1, the first link member 202 is provided with a protrusion 204 to protrude upward at intervals. The protrusion 204 is to adjust the steering angle of the front wheel 131 even by the operation of the first handle 150, the first handle member 154 around the third shaft (156) When rotated to the left and right, the first link member 202 is also to be moved to the left and right in conjunction with this. The protrusion 204 may be integrally provided so that a part of the protrusion 204 may protrude upward from the extension member 194. However, the protrusion 204 is preferably configured as shown in FIG.

That is, the protrusion 204 is elastically coupled to the fixing member 204a and one end fixed to the first link member 202 and the other end is coupled to the long hole 195 and the other end of the extension member 194 It is preferable to set it as the structure provided with the elevating member 204b which raises and lowers according to height. In this case, the protrusion 204 does not protrude above the extension member 194. And it is preferable to install a roller 205 or a bearing on the upper end of the elevating member 204b so as not to interfere with each other even when the extension member 194 moves back and forth. To this end, the extension member 194 has a roller guide groove 194a to allow the roller 205 to be inserted therein.

Herein, the protrusion 204, the first link member 202, and the second link member 203 installed between the first handle member 154 and the front wheel 131 may be connected to each other by the connection mechanism 194. It is an example of the interlocking means 200 for adjusting the steering angle of the front wheel 131 according to the left and right pivot angle of the first handle member 154.

That is, the interlocking means 200 may be rotatably installed on the first link member 202 and the first link member 202, and may be connected to the front wheel 131 to be connected to the first link member 202. Is installed on the second link member 203 and the first link member 202 to adjust the direction of the front wheels 131 as it is moved from side to side and connected to the connection mechanism 190 before and after the connection mechanism 190. It is configured to include a protrusion 204 for allowing vertical movement and moving the first link member 202 left and right by a force in the direction of movement of the coupling mechanism 190 when the connecting mechanism 190 moves left and right.

As described above, as the bicycle 100 of FIG. 1 embodiment rotates the pedal unit 170 by stepping on the foot member 192, the foot member 192 moves back and forth on the foot guide 220, and the foot guide 220. ) Rotates around the support point of the scaffold guide 220 and raises and ends the extension member 194. Accordingly, the extension member 194 rotates up and down about the support point of the first handle member 154, and thus the first handle member 154 is also shaken in the front and rear direction about the first shaft 152. work out. That is, the arm holding the upper end of the first handle member 154 can move the arm forward and backward. At this time, by pulling or pushing the first handle member 154 by hand, the rotation force may be increased on the pedal unit 170. At this time, the lifting member 204b of the protrusion 204 is elevated according to the height of the extension member 194 of the connection portion.

In this way, when the riding direction is to be changed while riding the bicycle 100, a force is applied to the first handle member 154 to the left or the right. Then, the first handle member 154 rotates around the third shaft 156 and rotates the extension member 194 connected to the lower end to the left or right about the second joint 196b. Accordingly, the protrusion 204 is moved to the left or right, and the first link member 202 connected to the protrusion 204 is also moved to the left or right. Accordingly, the second link member 203 is also rotated to adjust the direction of the front wheel 131.

That is, the first handle member 154 of the first handle unit 150 allows the arm angle to be moved while the pendulum moves back and forth while adjusting the steering angle of the front wheel 131.

On the other hand, when a person is holding the first handle 150 to exercise while riding a bicycle comfortably as in a normal bicycle, holding the second handle member 184 of the second handle portion 180 to hold the pedal unit 170 When the second handle member 184 is rotated to the left or the right while driving by rotating), the second shaft 182 rotates in the direction. Accordingly, the extension part 182a installed at the lower end of the second shaft 182 rotates to the left or right about the second shaft 182, whereby the first link member 202 moves in the horizontal direction of the left and right. One end of the second link member 203 is moved left or right. Accordingly, the steering angle of the front wheel 131 is also adjusted.

As described above, the hand run bicycle 100 according to the present invention illustrated in FIG. 1 may steer the front wheel 131 with only the first handle part 150, and pendulum movements before and after the first handle member 154. Since the arm movement can be performed in the direction, the second handle part 180 may be omitted in some cases.

That is, the second handle part 180 is not an essential component of the present invention.

However, it is desirable to have a second handle part 180 to allow a person to ride a bicycle comfortably and to ride a bicycle in various postures. Reference numeral 108 is a saddle.

4 is a bottom view of a hand run bicycle showing an example in which a spring is installed between the first link member and the second link member.

As shown in FIG. 4, a spring 206 may be installed between the first link member 202 and the second link member 203. The spring 206 serves to pull the second link member 203 so that the second link member 203 can be restored to its original position in a state in which the second link member 203 is rotated to one side. Preferably, one pair is installed between each of the second link members 203 and between the first link member 202 and the other second link member 203, and a pair of left and right sides is provided. The rest is as described with reference to FIGS.

It is connected. The second link member 203 is connected to the center of the front wheel 131. And between the center of the two front wheels 131 and the first link member 202 on both sides is provided with a spring 206 to provide a restoring force when the wheel 131 is steered and returned to its original position.

In the state of FIG. 9, when the second shaft 182 or the like is rotated in one direction, the extension part 182a is also rotated in one direction about the second shaft 182. 202 pulls the second link 203 connected thereto, and the first link member 202 on the other side pushes the second link 203 connected thereto to rotate the front wheel 131. At this time, one of the two springs 206 is tensioned and the other is contracted, the tensioned to provide a restoring force in the wheel 131 later.

Referring to FIG. 10, as the extension part 182a is rotated, the connection part with the first link member 202 of the extension part 182a has a distance from the center of the wheel 131 so that both sides are different from each other. The steering angles of the wheels 131 are different from each other. In the bottom view of FIG. 10, the right wheel 131 is steered at a larger angle than the left wheel 131.

As a result of the experiment of the present inventors, when the occupant steers the wheel 131 to the right while riding a bicycle, the steering angle of the left wheel 131 is larger than that of the right wheel 131 so that it can be easily turned to the right. Although the shapes shown in Figs. 9 and 10 are suitable for this.

The present invention is applicable to industries such as bicycles, especially exercise bicycles, amusement bicycles, rides.
