Description

Steering wheel folding device of two-wheeled vehicle {HANDLE FOLDER MECHANISM FOR LOW SPEED MOTOR CYCLE}

The present invention relates to a handle folding device of a slow two-wheeled vehicle, and more particularly, the operation is easily provided according to the folding by a simple structure, as well as maintaining a solid assembly state in the unfolded state to prevent misoperation and reliability in use. The present invention relates to a steering wheel folding device of an excellent slow motorcycle.

In general, two-wheeled vehicles include motor cycles that are directly driven by the engine's rotational driving force, or slow-moving two-wheeled vehicles (sometimes referred to as small motor cycles) by an indirect transmission method in which the vehicle is driven in a short distance by standing upright on a footrest. .

The slow motion two-wheeled vehicle is roughly composed of a front wheel and a rear wheel, a footrest, a support frame for supporting the footrest, and a handle frame at the front.

In such a slow two-wheeled vehicle, the handle frame is vertically formed to have a sufficient length so that the user can stand in an upright position on the foothold and grip the handle.

Therefore, since the space occupied by the handle frame is large, it is very inconvenient to store the motorcycle or carry and carry it in a certain place.

In order to solve this problem, U.S. Patent No. 4,821,832 divides the handle frame and pivotally connects the hinges to each other, inserting a support tube on the outside of the hinged portion, and supporting the support protrusion on the upper portion of the support tube. It is achieved by supporting the pipe to prevent it from falling off.

When the two-wheeled vehicle attempts to fold the handle frame, when the support tube is lifted upward while the supporting protrusion is pressed, the handle frame is rotated around the hinge while being exposed to the hinge connection portion.

In addition, when the folded handle frame is unfolded again, the handle frame is rotated to its original position (vertical state) by the hinge point, and the support pipe that is raised is pushed downward to wrap the hinge portion to prevent rotation.

However, such a two-wheeled vehicle has a risk of malfunction that the occupant presses the support projection or lifts the support pipe upward while driving,

In this case, the handle frame has a disadvantage of causing a safety accident while rotating in the front and rear directions.

In addition, in the process of folding operation, the support tube is raised while pressing the support protrusion, and the frame needs to be rotated in the state in which the support tube is raised.

In addition, the handle frame is not only folded back to the hinge point, but also has a drawback that requires attention in operation because there is a risk of rotating to unfold forward.

In addition, since the handle frame is connected to the hinge that forms a point with the lower fixed body in a vertically installed state, it is difficult to install a solid connection, so that the flow occurs at the hinge point, thereby reducing the passenger's riding comfort and causing a safety accident. Have

The present invention has been made to solve the above-mentioned problems of the prior art, it is an object to maximize the convenience to use the folding handle frame by a simple operation.

In addition, the present invention has a purpose of maximizing the reliability in use by preventing the passenger's riding feeling and safety accidents because the handle frame is maintained in a solid assembly state unfolded vertically.

The object of the present invention is to assemble the handle frame to be inserted into the lower fixing body of the handle frame, the fixing body is assembled to the hinge axis to the handle frame is moved up and down and rearward, but on one side of the handle frame It is achieved by a folding device configured to form a through hole to install and remove the lock pin of the lock mechanism to fix the handle frame on the fixture.

A hinge shaft 17 is formed in the fixed body 15, and a guide groove 18 is formed to cut the upper part at the rear thereof so that the handle frame 10 is rotated. The handle frame 10 has a high height. The guide groove 12 of the long hole is formed so as to be guided in the vertical direction of the hinge shaft 16 arranged in the stagnate 15, and assembled to the hinge shaft 16,

One side of the handle frame 10 is formed with a through hole 13 so as to insert the lock pin 35 of the lock mechanism 30 into the through hole 13 so that the handle frame 10 on the fixing body 15. ) Is fixed.

At this time, the lock pin 35 of the lock mechanism 30 can be implemented as shown in Figure 8, which is the lock pin 35 in the lower guide groove 12 of the handle frame 10 It is to be removed.

As shown in FIGS. 5 and 6, the lock mechanism 30 forms an assembly hole 31 a on one side of the main body 31, and an assembly screw part 32 a on one side and a guide hole inside the assembly hole 31 a. Insert and assemble the other side of the fastener 32 is formed so that the (32c) penetrates,

In the guide hole 32c of the fastener 32, one side is joined to the main body 31, and the other side is inserted into the lock pin 35 protruding to the outside of the fastener 32, the lock pin 35 The guide hole (32c) is made so as to be supported by the spring (34) built between the stepped jaw (32d) and the locking jaw (35d) of the lock pin 35 on one side.

At this time, the interval between the step 32d of the guide hole (32c) and the locking step (35d) of the lock pin 35 is the main body with respect to the movement distance that the lock pin 35 is wandering while compressing the spring (34) The inside of the assembly hole 31a of the 31 is formed so that the fixture 32 is larger than the sliding distance.

In addition, the assembling hole 31a of the main body 31 is formed with a guide groove 31b having an uneven shape, and the fixing tool 32 has a guide protrusion having an uneven shape corresponding to the guide groove 31b of the assembly hole 31a. 32b is assembled to be guided in the guide groove 31b.

As for the lock mechanism 30, the screw part 32a of the fastener 32 is screwed into the screw hole 19 of the fixture 15, and is fixed.

Reference numeral 10a denotes a handle handle of the upper portion of the handle frame 10, and 35c denotes a screw portion of the lock pin 35 that is screwed into the screw hole 31c of the main body 31.

Next will be described the operation and operation of the present invention configured as described above.

First, the process of folding the handle frame 10,

The lock mechanism 30 on the handle frame 10 is released from the locked state.

This, when pulling the main body 31 of the lock mechanism 30 installed on the handle frame 10, the lock pin 35 screwed to the main body 31 is drawn out by compressing the spring (34).

At this time, since the fixing tool 32 is screwed into the screw hole 19 of the fixing member 15 by the assembly screw part 32a, only the main body 31 and the lock pin 35 are pulled out.

In the above process, the spring 34 between the locking jaw 35d of the lock pin 35 and the step 32d formed in the guide hole 32c of the fastener 32 is compressed,

At the same time, the main body 31 has a guide groove 31b formed in the assembly hole 31a so that the guide protrusion 32b of the fixing tool 32 is guided constantly.

At this time, in the process in which the lock pin 35 compresses the spring 34, the interval between the stepped portion 32d of the guide hole 32c and the locking step 35d of the lock pin 35 is the main body 31. Since the fastener 32 is formed to be larger than the sliding distance in the assembly hole 31a of the main body 31, the fastener 32 is operated to slide away from the main body 31.

As described above, when the lock pin 35 is drawn out from the through hole 13 of the handle frame 10 and the lock state is released, the handle pin 10 is raised from the fixing body 15 in the vertical direction.

At this time, the guide groove 12 of the handle frame 10 is vertically raised while being guided to the hinge shaft (17).

In this state, the handle frame 10 is rotated to the rear of the hinge shaft 17 on the fixed body 15 to the point.

As a result, the process of folding the handle frame 10 is made by a simple operation since only the handle frame 10 is lifted and rotated in a state of releasing the locked state of the lock mechanism 30.

In addition, since the handle frame 10 can be folded while being rotated only rearward, there is a fear of misoperation.

In this way, when the handle frame 10 is rotated to the rear and folded, it is fixed by a separate clamp (not shown).

When the handle frame 10 is folded in this way, since the overall space occupancy is minimized, the portable frame is easily carried, stored, and transported.

On the other hand, looking at the process of assembling the folded handle frame 10 back to the original state,

Loosen the clamp to rotate the handle frame 10 vertically to the hinge axis (17).

At this time, since the handle frame 10 is inserted into the assembly hole 16 of the fixing body 15, rotation in the forward direction is prevented.

As such, when the handle frame 10 is vertically rotated, the handle frame 10 is guided downward along the hinge shaft 17 by the guide hole 12.

At this time, the handle frame 10 is caught by the lock pin 35 of the lock mechanism 30 is limited to the lowering operation.

As described above, when the lock pin 35 is pulled out by pulling the main body 31 of the lock mechanism 30, the handle frame 10 is moved into the inner assembly hole 16 of the fixture 15. Assembled fully insert

When the main body 31 of the pulled lock mechanism 30 is released in this state, the main body 31 is returned to its original position by the elastic force of the spring 34 in the compressed state together with the lock pin 35. The lock pin 35 is inserted into the through hole 13 of the handle frame 10 to fix the handle frame 10.

In this process, the guide groove 31b of the main body 31 slides constantly while being guided to the guide protrusion 32b of the fixture 32, so that the operation of inserting the lock pin 35 into the through hole 13 is accurate. Will be done.

The handle frame 10 fixed to the fixed body 15 is assembled in the state inserted into the assembly hole 16 of the fixed body 15, and also the hinge shaft 17 and the lock pin 35. By acting to fix at two points by the withdrawal and flow is prevented to maintain a solid assembly state.

Accordingly, the occupant can safely travel in a state in which the handle frame 10 is firmly fixed.

On the other hand, in another embodiment of the present invention in Figure 8, compared to the preferred embodiment of the present invention, the lock pin 35 of the lock mechanism 30 is inserted into the guide groove 12 of the handle frame 10 The operation and action are the same as in the above-described embodiment, except that they have a difference that is intended to be fixed.

As described in detail above, the present invention is to be folded by a simple operation of lifting and rotating the handle frame along the hinge axis in a state in which the lock mechanism is released, as well as the handle frame is guided by the folding operation along the guide groove, thereby causing a malfunction. Is prevented to maximize the convenience of use,

In addition, the handle frame is assembled in a state in which the handle frame is inserted into the holding body in a vertically unfolded state, as well as securely assembled in a state that is prevented from leaving the flow and assembled state in a locked state at two points. It will have the effect of maximizing the reliability of use by preventing ride improvement and safety accidents.
