The present invention allows the saddle holder including the saddle and the drive crank means (foot crank, crank housing and chain gear) to be elastically suspended from the upper frame by separating the upper and lower frames from the front and rear wheels. It's about bicycles.

In addition, the present invention relates to a bicycle in which the steering wheel itself is configured to be non-vibrating and handleable with respect to the front wheel steering shaft in addition to the stand-alone saddle holder.

It is known that the seat filter is elastically installed with respect to the saddle holder for the purpose of damping vibrations from the front wheel and the rear wheel against the saddle. However, in this type of bicycle, the drive crank means itself has a fixed relationship to the lower frame. Since the center of rotational movement of the crank means follows the fluctuation of the center of the front and rear wheels, the saddle position of the burnt person is relatively up and down due to the spring action when driving on the rough bottom. The position fluctuates greatly up and down, which makes driving difficult and fatigue.

Therefore, a first object of the present invention is to provide a bicycle in which the saddle and the crank means are independent of the front wheels and the rear wheels to eliminate transmission of vibrations from them.

A second object of the present invention is to provide a bicycle that can avoid the vibration of the front and rear wheels in addition to the first object described above.

Other objects and advantages of the present invention will be more clearly described with reference to the accompanying drawings showing the following embodiments.

Specific embodiments for achieving the above object in the present invention can be divided into the following two schematic aspects.

(A) The saddle and the driving crank means are installed above and below one saddle column, and are completely independent from the upper and lower frames to elastically suspend the upper frame by spring means (Examples 1 to 4 above).

(B) The main handle is coupled to the independent suspended saddle holder of (A) above and is separated from the handle (hereinafter referred to as the sub-handle) mounted between the conventional front wheel operation. The sub-handle is independently coupled to the upper and lower vibrating materials (Examples 5 to 6 below).

The two schematic embodiments will be described in further detail in the following order.

(A) The structures common in the embodiments 1-4 are the saddle holders 5 having the saddle 3 at the upper part and the driving crank means 4 at the lower part independently of the upper and lower frames 1 and 2, and the saddle holder 5 being described above. It consists of a means 6 for elastic suspension from the upper frame 1, the drive crank means 4 comprises a stepping crank 7, crank housing 8 and chain gear 9, the elastic suspension means 6 described above the saddle holder 5 The above structure includes a means for guiding the elevating and lowering of the half-frames 1 and 2, and a plurality of spring groups 11 that are lowered from the upper frame 1 against the weight of the saddle holder 5, and the elasticity described above. By dividing the specific aspect of the suspending means or further addition means thereinto, it is divided into Examples 1 to 4.

1 shows that in the first embodiment, the elastic suspension means is movable up and down between the two lower frames 2 and 2, like the upper frames 1 and 1 branched into two branches in the horizontal direction. Lift guide means 10 including a pair of upper and lower pairs 12 and 13 from each of the newly inserted saddle holders 5 and the upper frames 1, 1 and the lower frames 2 and 2, and the top fixed to the upper frames 1 and 1 Symmetry of the front and rear of the saddle post 5 by connecting the upper and lower hooks to the hook hooks 16 between the lower plate 15 fixed directly above the drive crank means 4 of the plate 14 and the saddle post 5, and between the upper and lower plates 14 and 15, respectively. Spring group 11 of plural tanks (pair = Pair, here four tanks) arrange | positioned at position. It consists of a spring means 6 comprising a. 16 is a hook ring mounted on the upper and lower end plates 14 and 15, and 17 is an upper plate 14 that stretches the upper plate 14 in the stretching direction of the spring group with respect to the upper frames 1 and 1. Adjusting bolt to adjust the elasticity of the.

Connections 12 and 13 are marked as being divided into two parts, but are not necessarily so branched. It is preferable that the loosening of the chain 18 by the vertical movement of the drive crank means 4 can be prevented by providing the idler gear 19.

In the second embodiment shown in FIG. 2, the elevating guide means 10 is a guide roller 21, 21 for interposing an external appearance 20 interposed between the upper frame 1 and the lower frame 2, and the saddle column 5 built up inside the exterior 20 from left and right. The upper and lower pairs of guide roller boxes 22 and 22 having a built-in structure are fixed to the upper frame 1 and the lower frame 2, respectively, and the spring means 6 is the same as that of the first embodiment.

The saddle column 5 is a hexagonal hollow tube having a cross section as illustrated in FIG. 3, and the guide rollers 21 and 21 corresponding to the saddle column have a cross section of a bobbin shape, but are not limited thereto. It is not. In order to fix the guide roller boxes 22 and 22 to the upper and lower frames 1 and 2, high information bolts 23 and 23 are installed.

In Examples 1 and 2, the saddle holder 5 maintains a completely independent elastic suspension relationship with respect to the upper and half laminations 1 and 2, and the moment of the whole man's middle and pedaling movements. (Moment) is supported by the saddle holders 5, so that the saddle holders 5 are spring groups 11... Even in the up and down vibrations of the front wheels 24 and the rear wheels 25. In the elastic deformation range of, almost no movement up and down, and the relative relationship between the saddle 3 and the pedal 7 is constant, so the pedaling operation of the tanner is always the same even on a bulging road.

Therefore, the vibration transmitted to the person who rides between the saddle 3 is sufficiently blocked, and the pedal operation is always constant. Therefore, even in a long road with severe unevenness, the rhythm of pedaling is hardly missed and there is a big advantage that little fatigue is felt. .

At the same time, the spring group 11... Of the weight of the saddle column 5. Since the front wheel 24 and the rear wheel 25 are always pushed on the road, the closeness between the two wheels 24 and 25 and the uneven road surface is good and there is no injury, so the driving is light and the kinetic energy loss is small.

As indicated by the dashed line in FIG. 8, even when the front wheels 24 and the rear wheels 25 move up and down, and thus the upper and the half rims 1 and 2 oscillate up and down, the saddle holder 5 of the present invention is elastic by the upper and the half rim spring means 6. Because of the suspension, the upper and lower vibrations of the frames 1 and 2 described above are performed independently of the saddle holder 5 and do not transmit vibration to the prop 5.

In other words, the vibration is effected by compressing or stretching the spring means 6 without essentially changing the position of the saddle post 5. Therefore, the winner's relative position with respect to the ground is almost constant with respect to the uneven surface of the road.

And spring group 11... Tension of bolt 17... This allows you to choose the right spring action for any weight difference. For example, if you are a light weight person, Some of these may be separated from hook ring 16 in advance. Spring 11 is suitable for elastic steel wire with long and flexible elasticity.

If the position where the spring group 11 is extended is called the neutral position according to the weight of the saddle holder 5 carrying the person, the spring group 11 is stretched about the same length up and down than the neutral position, and the line, rear wheel 24, 25 Absorbs up and down vibrations.

As compared with Example 1, it can be easily understood that in the case of Example 2, ascending and descending of the saddle holder 5 can be made easier by the narrowing of the guide rollers 21 and 22.

In Embodiments 3 and 4, in the above embodiment, a means for actively preventing rotation occurring around the shaft center of the saddle holder 5 is adopted, and in particular, the above-mentioned force that can occur when rotating by applying a sudden force to the drive crank means 4 is described above. There is care to prevent rotation.

That is, the elastic suspension means shown in FIG. 4 is the same as that of the second embodiment, but the pivot support means 26 of the strut 5 is marked as the swing lever 27 connected between the lower plate 15 and the lower frame 2. In Fig. 5, the bearing pins 150 and 150 are provided at the front end of the lower plate 15, and the shaft pins are interposed between the hollow parts of the bearing parts 150 and 150 with the hollow parts of the blade piece 280 of the flat T swing lever 27. Insert the 29 and fix the shaft pin 29 with screw 290, 290 so that it cannot be rotated, and the longitudinal lever 30 with the longitudinal hole 300 installed at the bottom is directed from the lower frame 2. One end of the interstitial 28 of 27 is inserted into this longitudinal hole 300.

In this way, the swing lever 27 pivots up and down with one end pivoted to the shaft pin 29 in response to the ascent of the saddle holder 5, while the other end of the swing lever 27 is pinched by a hollow wall of the longitudinal hole 300. Can be. In Example 4 shown in FIG. 6, the rotation stopping means 26 is configured using a pair of upper and lower pairs 31 and 32 connected to the upper and upper frames 1 and the lower plate 15 and the lower frame 2 of the saddle column 5, respectively. It is. More specifically, as shown in FIG. 7, the rear end branch 31 of the upper connection to the clamper 33, which is clamped just below the saddle 3 of the saddle holder 5, Section 310 is extracted with a pivot 34 and branches from the upper frames 1 and 1 on the other side. ) The stand 311, 311 is directed to the front end 31 of the upper connection and the stand 311, 311 and the pivot by the pivot 35.

36 is a control pin of the clamper 33, 37 is a fixing screw of the pivot 34. The lower connecting rod 32 has the same structure as the upper connecting rod 31 between the lower plate 15 and the lower frames 2 and 2, as shown in FIG. In other words, the basin stands 38 and 38 are protruded from the lower frames 2 and 2, and the shaft bosses 39 and 39 are again installed on the stands 38 and 38, and the shaft bosses are installed at the front end 31 of the upper connection. 40 and the shaft bosses 39 and 39 are extracted with the pivot 41, and the pivot 44 is placed between the bearings 43 and 43 formed at the front end of the lower plate 15 and the branch 42 provided at the rear end of the lower connection 32.軸 架), and the rear end of the lower connection 32 and the lower plate 15 are crushed. 45 is the fixing screw of the pivot 44.

In this embodiment, since the upper and lower plates 15 of the saddle column 5 and the upper frame 1 and the lower frame 2 are connected 31 and 32 between the two connections, the rotation stop function of the saddle column 5 is lower than that of the fourth embodiment. You will be more hungry. According to these two embodiments with the rotation stopping means 26, since the rotation when the pedal is sprinted is prevented, the saddle 3 can be smoothly moved up and down to obtain a comfortable driving feeling.

Embodiments 1 to 4 are bicycles adopting only the "independent elastic suspension mechanism" of the saddle holder. The following two embodiments are examples of bicycles which are assembled to this saddle support so that the handle is independent only with respect to the vibration of the front wheels (but the turnability is the same as before).

(B) In Examples 5 and 6, the saddle holder 5 and the elastic suspension means are common to those of Examples 1 to 4 (Example 2 in the drawings). The "handle mechanism" is constructed as follows.

9 and 10, the handle mechanism connects the rear end to the saddle holder 5, which has been posted independently from the front wheel operation shaft 46, and is moved up and down with respect to the head shaft 46. Left and right sub-handle levers 48 coupled to the swinging main handle 47 and the head shaft 46, and pin coupling means for connecting the sub-handle lever 48 and the main handle 47 up and down and swinging freely. Consists of 49.

More specifically, the main handle 47 extends perpendicularly to one branch axis 501 branched at the front end of the horizontal axis 50 along one horizontal axis 50 in the front and rear directions where the rear end is coupled with respect to the saddle column 5, and the branch part 501 perpendicularly. A pair of longitudinal saves 51, 51 fitted to the vertical closing levers 502, 502, and a pair of main handle levers 471, respectively, bent in the left and right directions to be connected to the save 51, 51, respectively. And 471, and the engagement pins 473, 473 vertically extended close to the handle 472.472 of the main handle levers 471, 471 and vertically sliding on the head shaft 46, and also the longitudinal sleeve 51, It is composed of 51 connecting bridges 52. The subhandle lever 48 is a T-shaped lever with long elliptical pinholes 481 and 481 that can flexibly fit 473 and 473 coupled to both ends. .

According to the above configuration, the upper and lower vibrations of the head shaft 46 are first transmitted to the subhandle lever 48. However, the subhandle lever 48 and the main handle 47 are connected by the up-and-down movement of the coupling pins 473, 473 and the pinholes 481, 481. At the same time, due to the sliding fit between the head shaft 46 and the connector 52, the vibration of the sub handle lever 48 is not transmitted to the main handle 47.

However, when the main handle 47 pivots around the vertical shafts 502, 502, this turning force is transmitted from the sub-handle lever 48 to the head shaft 46 through the pin coupling means 49 to enable the steering operation of the front wheel 24.

According to the present invention, according to the present invention, the driver has his body and hands integrally suspended with respect to the frames 1 and 2 by the spring means 6, so that the up and down vibration due to the unevenness of the road surface is not only the body of the driver. You won't be delivered to your hands, so you can feel extremely comfortable.

In the sixth embodiment, the handle mechanism is prevented from rotating again. 11 and 12 show the handle vibration preventing means 53 (where vibration refers mainly to shaking). This means 53 is provided between the aforementioned horizontal axis 50 and the branch portions 501 and 501, and indirectly inverts the ball bearing casing 54 and the ball bearing casing 54 which are placed on the period 5010 above the horizontal axis 50 and the branch portion. (轉接) includes a pair of guide bars 55 and 56 arranged at an angle equal to the saddle post 5 between the upper and the half laminations 1 and 2.

12, the one end of the horizontal axis 50 is comprised by the hollow plate 503 with the internal thread 504 formed in the inner surface, and the male thread 5011 is formed in the outer periphery of the period 5010 mentioned above.

A botcing 57 with a female thread 571 corresponding to this male thread 5011 is inserted into the inner race 541 of the ball bearing casing 54 and the female thread 571 of the botcing 57 is combined with the male thread 5011 of the above period 5010 and the other end of the 5010 period out of the botcing 57 It protrudes.

The hollow plate 503 and the botsing 57 are fixed by this male screw 5011. 58 is a ball bearing.

The left and right pairs of guide sections 55 and 56 are cross-linked templates between the upper frames 1 and 1 and the lower frames 2 and 2, leaving a slight gap between the inner surface and the outer race 542 of the ball bearing casing 54 described above.

Because of this configuration, because of the uneven road surface or sudden driving force applied to the driving crank means 4, even when the saddle holder 5 moves up and down, the ball bearing casing 54 is engaged with one or both of the guides 55 and 56 and rotates smoothly. Since this is done, the handle characteristics and driving characteristics can be improved.

Although various preferred embodiments have been described with reference to the present invention, the present invention is not limited to the structure exemplified above, and various substitutions, additions, changes, deletions, etc. within the scope not departing from the scope of the claims for utility model registration. This structure can be employed.
