Description

Tricycle with cambering mechanism device {CAMBERING VEHICLE AND MECHANISM}

The present invention relates to a three-wheeled bicycle having a cambering mechanism, and more particularly, having three small wheels for generating propulsion by a user, and stirring gravity movement from one side to the other side. A tricycle having a cambering mechanism device having a forward momentum when present.

The three-wheeled bicycle according to the first embodiment of the present invention is located between a plurality of support shafts for the rear wheels, and has a new type of coupling device for linking the plurality of support shafts to enable stirring movement. In addition, easily removable fittings provide the convenience of folding the bicycle for storage.

In a second embodiment of the invention, the fixable and non-separable transverse link replaces the fitting, providing a relative movement between the end of the link and the arm together with the flexible bushing.

The support shaft also has a folding means for compact storage of the bicycle.

In general, "camber transport" refers to a tricycle that moves along a sinusoidal path because of the law of angular momentum conservation. The bicycle type, with three small wheels to generate propulsion by the user, has one steerable front wheel and a pair of lateral spacings on the support shaft jointly coupled to the front axle extending from this front wheel. Has the rear wheel. When the bike moves on a sinusoidal path, the user moves his or her weight inwardly of each circular arc, so that the center of rotation is moved inward of each circular arc. As a result, acceleration is continuously generated due to the preservation of the exercise amount of the bicycle and the user. In this way, forward movement occurs.

The propulsion principle is a well known fact as described in at least one registered patent to be described below. These bicycles use a variety of mechanisms (cables, pulleys, gears, bell cranks, etc.) to simultaneously link a plurality of support shafts, which are mentioned in the related art described below.

On the other hand, the tricycle of the present invention uses a new type of fitting mechanism device for simultaneously connecting a plurality of support shafts, and also allows the fitting to easily fold the bicycle by means of a single fitting removal means. Can be different.

The second embodiment of the invention also includes a transverse link, with a flexible bushing for engagement of the arm at each end. The bushing provides the elastic energy required for the relative motion between the end of the link and the end of the arm.

In the following, it will be described with respect to the prior art having differences and distinctions compared to the present invention in accordance with the review of the related art grasped by the inventor.

U.S. Patent No. 4,045,048 is a 'support shaft cambering vehicle with a stabilizing link device having parking and loading fixing means' acquired by Clarence C. Irwin on August 30, 1997. Disclosed is a cambering vehicle in which support shafts are connected to a bell crank pivotally attached to the front shaft, such as an attachment point. The plurality of arms are connected to the bell crank by push rods. The fastening plate has an arcuate hole and a screw fastening pin extending toward the hole to allow the screw handle to fasten the mechanism device in a fixed position for vertical storage of the bicycle.

However, the prior art folding mechanism device is relatively complicated compared to the bicycle of the present invention, and in that respect the patent of the applicant "Irwin" requires both a link of a complicated configuration to be removed and a bell crank connected thereto. There are disadvantages.

Further, the patent of the prior art application "Irwin" does not disclose any form of flexible connection structure between the fit coupling device or the mechanism device provided in the first embodiment of the present invention.

U.S. Patent No. 4,047,732 is a "cambering vehicle with a hydraulic stabilizer and balancer" acquired by Jerry K. Williams and his colleagues on September 13, 1977, an interconnected hydraulic cylinder connecting a plurality of support shafts. It is very similar to the bicycle of patent '048' of the above-mentioned applicant "Irwin" except that it has a. Here, the systematic function is the same as or similar to "Irwin" Patent No. 048 in that the opposite cylinder contracts when one cylinder is extended. Valves have been used to block the flow of hydraulic forces between a plurality of axes to fix the desired position of the bicycle. The valve regulates the flow of fluid from one of the plurality of cylinders to the other, thereby allowing the plurality of cylinders to be detachable at the same time to fold the bicycle.

The present invention described below does not use fluid or hydraulic pressure, and furthermore, does not require any form of interconnection between the support shaft and the fitting, but uses a fitting member to connect the plurality of support shafts.

In contrast, the patents of Williams and colleagues of the prior art do not have any form of flexible fit coupling device or connecting means which mutually couple cambering components as provided in the embodiments of the present invention. It is not.

Accordingly, an object of the present invention is to provide a three-wheeled bicycle having a camber mechanism device that is simple to store and use by providing a fitting connection structure.

Another object of the present invention is to provide a tricycle having a camber mechanism which can operate smoothly by the elastic force of the flexible connection structure and can exhibit an improved function with a new type with little operating noise.

In addition, another object of the present invention is to provide a three-wheeled bicycle having a camber mechanism mechanism that can fold the bicycle quickly and easily by providing a one-touch fork long mounting structure for storage.

First Embodiment

In the drawings, Figure 1 is a perspective view for explaining the general appearance of a three-wheeled bicycle having a cambering mechanism device of the present invention, Figure 2 is a front in a three-wheeled bicycle having a cambering mechanism device according to a first embodiment of the present invention It is an enlarged view which shows the fitting mechanism apparatus in detail in order to demonstrate the some support shaft and its operation relationship as a back shape of an axis | shaft. 3 is a right side view illustrating the operation relationship of the fitting mechanism device shown in FIG. 2, FIG. 4 is a partial perspective view of the fitting mechanism device shown in FIGS. 2 and 3, and FIG. 5 is a three wheel shown in FIG. 2. It is a left side view for demonstrating the folding structure of a bicycle.

1 shows a tricycle 10 having a camber mechanism device of the present invention.

The bicycle 10 of the present invention basically includes a triaxial frame 12 having a front shaft 14, a left support shaft 16, and a right support shaft 18.

The support shafts 16, 18 are pivotally engaged at the top of the lower end 20 of the front shaft 14.

The detailed coupling relationship between the support shafts 16 and 18 and the front shaft 14 can be clearly seen through FIGS. 2 to 4.

That is, the support shaft coupling portion 22 is fixed to the front shaft 14 in a direction perpendicular to the axial direction of the front shaft 14 at the upper end of the lower end portion 20 of the front shaft 14, the support shaft coupling The part 22 provides the support shaft engaging hinge portions 24 and 26 which are arranged so that both ends thereof face oppositely with respect to the front shaft 14. Support shaft bushings 28 and 30 having holes penetrating in the lateral direction are formed at the front ends of the plurality of support shafts 16 and 18 on the left and right sides. The support shaft bushings 28 and 30 are supported by the support shaft engaging portion of the lower end 20 of the front shaft 14 so that the support shafts 16 and 18 are hermetically coupled to the support shaft engaging portion 22 in a pivotal manner. And inserted into the support shaft engaging hinge portions 24 and 26, respectively, and then by bolt 32 or other suitable movement limiting means.

As shown in more detail in FIG. 4 or FIGS. 6-8D, the fitting 34, which is a link coupling, for the coupling of the connecting link or the transverse link or fitting 40 is perpendicular to the lower end 20. It is positioned to extend rearwardly on the circumferential surface of the front shaft 14 corresponding to the center between the plurality of support shaft engaging hinge portions 24 and 26 arranged in the lateral direction from the top.

The fitting coupling portion 34 has a relatively small diameter, extends rearward, and has a screw shaft 36 threaded on the inner circumferential surface. In addition, the fitting coupling portion 34 is pivotally mounted and detachable to the pivot passage portion of the central bushing portion 38 of the fitting 40 which connects the support shaft by a single fitting engagement hole 42 such as a screw bolt or the like. Combined.

This coupling means is similar to hermetically coupling the plurality of support shafts 16, 18 to the support shaft coupling portion 22 of the lower portion of the front shaft 14.

The fittings 40 are spaced apart from each other by the diameter of the central bushing portion 38 fixed by welding or the like so as to serve as a central connecting link between the upper rod 44 and the lower rod 46. Upper rod 44 and lower rod 46 in parallel.

The distance between the plurality of fitting rods 44, 46 is basically such that when the fitting 40 is engaged with the fitting engagement portion 34 of the front shaft 14, it can hold the plurality of supporting shafts 16, 18. It is equal to the diameter of the plurality of support shafts 16, 18. Here, the left ends 44l and 46l of the plurality of fitting rods 44 and 46 hold the left support shaft 16 therebetween, and the right ends 44r and 46r are the right support shafts between them. (18) is holding onto. The working structure of the fitting 40 will be readily understood through the back and right side shapes of FIGS. 2 and 3. In each figure, the central or neutral position of the fitting 40 and the plurality of support shafts 16, 18 held by the fitting 40 are indicated by solid lines, with the top and bottom positions positioned. The actuated support shafts 16, 18 and correspondingly located fitting rods 44, 46 are indicated by dashed lines. 2 is an exemplary representation of a state in which the bicycle 10 is inclined or tilted in a right direction. That is, the upper position of the support shaft 18 of FIG. 3 and the right support shaft 18 are deflected upwards like an arc as shown by the dotted line in FIG. At this time, the right end portions 44r and 46r of the fitting rods 44 and 46 will follow the upward movement of the support shaft 18 in accordance with direct contact.

As a result, 40 fittings arcuately hinged to the central bushing portion 38 and the fitting engagement portion 34 toward the rear face of the front axle 14 and on the opposite side of the fitting rods 44, 46. The left ends 44l and 46l face downward. At this time, the left end portions 44l, 46l of the fitting rods 44, 46 are in direct contact with the left support shaft 16, and therefore, the left support shaft 16 is deflected upwards like an arcuate shape.

Theoretically, the amount or distance traveled by each of the support shafts 16, 18 in an arcuate deflection can vary depending on the deviation corresponding to equidistant distances from the fitting engagement 34.

As a result, by hinge operation of the fitting 40, the plurality of support shafts 16, 18 will always move in opposite directions.

Fitting interconnection of the plurality of support shafts 16, 18 provides additional advantages.

As described above, the fitting 40 is coupled to the front shaft 14 of the bicycle 10 in a detachable manner by a single fitting fastener 42 such as a bolt or the like.

When removing a single fitting tie 42, the fitting 40 can be detached from the fitting coupling 34, thereby eliminating the complete interconnection between the plurality of support shafts 16, 18. Will be.

Since the single fitting fastener 42 and the fitting 40 can be easily removed, the plurality of support shafts 16 and 18 can be rotated at the same time so that they can be placed almost or completely horizontally with the front shaft 14. do. In other words, in order to provide a compact contour for storage as indicated by the dashed line in FIG. 5, the front shaft 14 may be folded downward close to the plurality of support shafts 16, 18. will be. This will not be practically limited in providing the arcuate movement of the plurality of support shafts 16, 18 while corresponding to the arcuate movement of the fitting 40 by the structure as described above. Thus, any form of stopping means can be provided which prevents excessive tilting of the bicycle 10 in operation and excessive arching of the support shafts 16, 18.

2 and 4 represent the support shaft stop means of the bicycle 10 of the present invention, the vertical stop of the fitting coupling portion 34 to the transverse stopper 48 fixed to the rear circumferential surface of the front shaft 14 Include.

The stopper 48 preferably includes a cross strut 50, and the stopper 48 and the cross strut 80 are formed in a triangular shape, as shown.

Fittings 40 which limit the opposite arcuate movement of the opposite arm, including the interconnection of the opposite support shaft, when the left or right support shafts 16, 18 are in contact with the corresponding side of the stopper 48, respectively. By means, the arcuate movement is limited. Preferably, the stop means can of course be manufactured in other shapes, such as a flat plate fixed to the rear circumferential surface of the front shaft 14.

The three-wheeled bicycle having the cambering mechanism device of the present invention has been described with reference to the drawings as a vehicle having wheels, but, for example, sliding surface contact means such as inline wheels or other types of wheeled skates, ice skates, skis, or the like; It goes without saying that it can be manufactured in a conventional type of rolling means.

The operation of the angular momentum conservation law used by the bicycle 10 of the present invention is not limited by the rolling means, but any minute friction ground when the bicycle 10 passes through the ground where a small friction loss occurs. Affected by contact.

As shown in FIG. 4, the tricycle 10 of the present invention illustratively has a steering shaft 52, which steering shaft 52 extends from the lower end 20 of the front shaft 14. In the front end 54, a front wheel shaft 56 having a single steerable front wheel 58 is formed (see Figs. 1, 2, 3, and 5).

The steering shaft 52 has an upper end 60 extending above the upper end 62 of the front shaft 14. As shown in FIGS. 1 and 5, the upper end 60 of the steering shaft 52 provides steering means, such as a handle 64, to allow a user to steer the bicycle 10 of the present invention. Include.

When turning the handle 64 (or any other steering means available) at a finite rotation angle so that the bicycle 10 can be steered in the desired direction, the steering wheel 52 and the front wheel in the front axle 14 are correspondingly corresponding. The front wheel shaft 56 with 58 (or the aforementioned ground contact means) is deflected.

Each support shaft 16, 18 has a rear end with a ground contact means such as rear wheels 70, 72: any means alternative to skating, skiing, etc., optionally shown in FIGS. 1 and 5D. 66, 68).

Bicycle 10 of the present invention can produce a speed that can feel more speed and moderate speed than a fast gait on a horizontal and smooth ground, the plurality of rear wheels 70, 72 are mutually independent left and right brakes It may include a conventional brake means formed by.

As shown in Fig. 5, by the normal operation or control means such as the brake actuation lever 74 or the like which is the separate brake control means, the left and right brakes of the rear wheels 70, 72 are separated and move independently. Although not shown, it will be fully understood that the brake of the right rear wheel 72 is provided at the right handle portion of the handle 64.

The plurality of brake actuation means is actuated by left and right brake cables 76, 78.

The user (0) of the present invention, while holding the handle 64, the left and right footrest located on the top of the rear wheels 70, 72 of the rear ends 66, 68 of the plurality of support shafts 16, 18 (80, 82) The bicycle 10 of the present invention is operated while standing above.

Then, the user 0 pushes either foot toward the angular momentum formed by the bicycle 10 and the user 0 and simultaneously turns the bicycle finitely to the left or to the right. The inclination thereby moves the center of gravity of the user (0) and the bicycle (10) inward of the rotation.

As angular momentum is conserved, as the center of gravity moves at a smaller radius, a linear acceleration occurs along the arcuate path of rotation, which is dependent on the amount of movement of the center of gravity of the bike and the user, excluding some loss of friction. Will respond.

The inclination of the bicycle 10 which is inclined inwardly of the rotation allows the plurality of support shafts to move in an arcuate shape, with the same but mutually limited arcuate movement in the opposite direction by the fitting interconnection means of the present invention.

The above-described process proceeds continuously in the opposite direction in accordance with the movement of the gravity center of the user 0 and the bicycle 10 inwardly in turn, and as a result, linear acceleration occurs along the arcuate path of the movement of the bicycle 10. do. The speed of the bicycle 10 appears very high above the horizontal and smooth ground and can be controlled by the independent brakes of the rear wheels and at the same time assist the steering of the bicycle 10 by any manipulation of the user.

Second Embodiment

The three-wheeled bicycle having the cambering mechanism device of the present invention described in this embodiment is the same as the first embodiment except that the transverse link and the flexible arm connecting means are attached to the steering shaft coupling structure. Therefore, detailed descriptions of the same or corresponding components in FIGS. 1 to 8D will be omitted here, and for corresponding components for reference, reference numerals of the hundredth series will be used. For example, the front shaft 14, fittings 40, etc. that were used in FIGS. 1 through 5 will be represented by the front shaft 114, cross link 140, and the like in FIGS. 6-8D.

6 is a cross-sectional view of a cross link cut to explain a steering shaft coupling structure of a tricycle having a cambering mechanism device according to a second embodiment of the present invention, and FIG. 7 is a cross link shown in FIG. 8A to 8D are views for explaining an operation relationship of the flexible material of the cross link shown in FIG. 6.

As shown in the top and left side views of FIGS. 6 and 7, the agitated and transversely arranged transverse link 140 is a link engagement portion 134 extending rearward from the front shaft 114 in a pivoting manner. ) Is confidentially combined.

The link coupling 134 is essentially the same as the fitting coupling 34 shown in FIG. 4. Here, the transverse link 140 has a connecting passage portion or a central bushing portion 138 positioned at the center for engaging the front shaft 114.

It is preferred that a nylon or other bushing material be provided between the material of the transverse link 140 and the binding bolt or pin 142 to reduce the friction between the components.

In the figure, the cross link 140 is installed for almost permanent use by mounting the retaining pins 142 almost permanently to the link engagement portion 134 or the link fastening boss.

In any case, the permanent installation of the transverse link 140 and the fixed endless engagement manner prevent the transverse link 140 from being easily separated from the plurality of support shafts 116, 118, and therefore, the cross link 140. To be removed from the link coupling portion 134 or the boss where the fitting 40 of the first embodiment was located.

Means are provided for folding the plurality of support shafts 116, 118 so that the bicycle can be compactly stored. In a conventional folding method, an inner cylinder and a rod are formed like a telescope cylinder, and pin holes are formed in one rod of the support shaft, and pin holes are formed in corresponding positions in the inner cylinder to which the support shaft is coupled. A plurality of fixing pins may be fastened to the pin holes, respectively, to fix the support shaft and to fold in a hinged manner.

In addition, although the folding means is not shown, it forms a fork shape at one end of each support shaft and has a narrow width relative to the support shaft at the side of the transverse link, so that the hinge end is hinged in the inserted state. After forming, it can be realized as a folding mechanism of the one-touch fork mounting and detachment structure consisting of the one-touch lever coupled to be supported by the elastic force of the spring.

Hereinafter, the steering shaft coupling structure according to the second embodiment will be described in detail.

The front or mating ends 124, 126 of the plurality of support shafts 116, 118 include support shaft bushings 128, 130. The support shaft bushings 128 and 130 are fitably coupled to the support shaft coupling portion 122 extending in a direction perpendicular to the outer circumferential surface of the front shaft 114.

After the bolt or pin 132 passes through the plurality of support shaft bushings 128 and 130 and the support shaft coupling portion 122, the plurality of support shafts on the front shaft 114 are similar or the same as the method described with reference to FIG. 1. (116, 118) is hermetically coupled.

On the other hand, the plurality of support shafts 116, 118 is different from the components that are indicated by the reference numeral '16', '18' in the bicycle 10. In other words, the plurality of support shafts 116, 118 in the second embodiment are integrally provided with link engagement bosses or passage portions 117, 119 which penetrate the body in the transverse direction.

The link coupling passages 117 and 119 serve as coupling sites for coupling the transverse links 140 to the respective support shafts 116 and 118.

The transverse link 140 is formed of a relatively thick, heavy and strong metal (such as steel) to provide the desired twist and bending strength, bending strength, and the like.

The transverse link 140 has flexible bushings 141 and 143 as flexible arm connecting means, respectively, on its left and opposite sides.

As can be seen from the shape of FIG. 6 and other figures, each of the flexible bushings 141, 143 includes an outer and inner shell or sleeve 145, 147 which are bound together by a flexible material 149. have.

In the flexible bushings 141, 143, each sleeve 145, 147 is secured by an elastic flexible material 149, and two sleeves (to the extent allowed by the elastic flexible material 149) are allowed. 145 and 147 have relative movements. That is, in the second embodiment no mechanism or movement is provided other than the flexible bushings 141 and 143.

The outer sleeve 145 of the flexible bushings 141 and 143 is fixed to the inner circumferential surface of the link coupling passage portions 117 and 119 of the plurality of support shafts 116 and 118 by a fixed method such as pressing or the like. The inner sleeve 145 of 141 and 143 is fixed to both ends of the transverse link 140 to which the shaft fixing bolt 151 is hermetically fixed, similarly to the fixing method.

Thus, the resilient means of the flexible material 149 of the flexible bushings 141, 143 provides relative movement between the transverse link 140 and the plurality of support shafts 116, 118.

8A and 8D illustrate the movement of the transverse link 140 and thus the bending deformation of the flexible material 149 of the flexible bushings 141 and 143.

As shown in FIG. 8A, when the right support shaft 118 moves downward with a deviation, and the left support shaft 116 moves upward with a corresponding deviation, the support shafts 116 and 118 are engaged. Shows a cross-section of the cross link 140 with the flexible bushings 141, 143.

The rigidity of the transverse link 140 is shaken forward or backward with respect to the central bushing portion 138 like an arch, but the front shaft 114 by the link coupling portion 134 and the binding bolt or pin 142. It stays connected to.

Thus, as the torsion of the flexible material 149 is clearly shown in FIG. 8A, their relative movement between the link ends and the link engagement passages 117, 119 of the support shaft is characterized by the plurality of flexible bushings 141, 143. Attenuated by a flexible material 149 in

The transverse link 140 and the support shafts 116, 118 are moved while the flexible material 149 makes some degree of freedom movement, such as any arcuate or hinge operation, between the link ends and the support shafts 116, 118. It leads to a direct but resilient state.

If all differential forces exerted on the plurality of support shafts 116, 118 are released, the elasticity of the flexible material 149 in the two flexible bushings 141, 143 exerts a restoring force, and consequently The plurality of support shafts 116 and 118 are returned to their original parallel state, and the elastic force of the flexible material 149 becomes the same.

The calm state in this embodiment is shown in Figure 8b. Here, the flexible material 149 is disposed identically to each flexible bushing 141 and 143 lying without any distortion.

The flexible bushings 141 and 143 and the transverse link 140 as the connecting means and the stable upright parking means shown in FIGS. 6 and 8D make it possible to provide a tricycle having the following effects.

That is, since there is no need to have any relatively slippery member between the link end and the support shaft, no lubricant supply is necessary for its coupling.

In addition, as the support shafts 116 and 118 vary with relatively large angular differences, an increase in the resistance of the flexible material 149 generates a restoring force that contributes to stabilizing the bicycle, and also prevents overturning of the bicycle. Excessive deviation between the plurality of support shafts 116 and 118 generated can be eliminated in advance.

Also, as shown in FIG. 1, a plurality of support shafts 16, 18 require the transverse struts 50 of the stopper to prevent excessive angular differences, while the second as shown in FIGS. 6-8D. In the embodiment, with the increased resistance of the flexible material 149, no configuration, such as a stopper, is required for the flexible connection means and the cross link.

In addition, the flexible joint coupling plays a role of cushioning in response to the asymmetrical impact amount that may occur when passing through irregular ground such as an unpaved road.

In addition, as the tires of the transport means with tires absorb such impacts and forces, as opposed to skates, skis, etc., the flexible material acts as a buffer against external forces as is known in the various mechanisms of the transport means. It can provide a resilience ability to absorb the impact of.

Finally, the force to be equalized is generated by the flexible material 149, and the plurality of support shafts 116, 118 are returned to the neutral position, and as a result, the parking and the like are attempted with all external forces removed. When you do, it allows the bike to stand upright.

That is, the elasticity of the plurality of flexible materials 149 in the flexible bushings 141, 143 prevents the plurality of support shafts 116, 118 from rubbing against each other, and consequently without providing additional support means. The road should be erected in a stable and upright position in the parking position.

FIG. 8C shows the configuration of the transverse link 140, the flexible bushings 141, 143, and the link engagement bosses 117, 119, while the left support shaft 116 moves downward with deviation. , When the right support shaft eventually moves upward, for example, the opposite of the situation of FIG. 8A.

The bending deformation of the flexible material 149 in the plurality of flexible bushings 141, 143 shows the opposite shape as shown in FIG. 8A, and the support shafts 116, 118 are also deflected oppositely.

As a result, the restoring force for returning the support shafts 116, 118 to the neutral position as shown in Fig. 8B is still applied.
