Description

 Wheeled Sled {A skate board with ertractable wheels}

The present invention relates to a sled with a wheel. More specifically, a wheel body is disposed at each of the front and rear centers and both sides of the bottom surface of the main body, and a saddle for height adjustment and disassembly is mounted on the upper surface thereof. One of the sticks is provided with a braking means and a lever for operating the braking means so that it is not restricted by time and space and can stir the sticks with both hands regardless of the season. In addition, it can be used as an all-purpose exercise equipment that can be enjoyed and enjoyed at the same time as it can greatly contribute to the muscle development of the upper body as well as the lower body of the user through such a driving, and can also be used regardless of the body size of the user. Adjust the height to stand up and stir the stick with both arms. If necessary, sled freely even in a comfortable sitting position. It is designed to be able to ride, to operate the braking means through a stick to accurately perform the speed and braking of the main body, as well as to easily check the driving state at night by the light emitting unit installed at the rear of the main body.

In general, sports equipment, called roller blades or inline skates, which are deformed in winter skating, is fastened by fastening the road surface by mounting a plurality of wheels on a bracket installed on the sole of the sole of the shoe. It is designed to drive at speed.

In addition, a variety of new sports equipment, such as skateboards, which can be driven by sleds or snowboards that children enjoyed in winter, can be equipped with a number of wheels on the bottom of the flat board and can run on the road regardless of the season. Is being developed.

In this application, as disclosed in Korean Patent Application Laid-Open No. 89-20743, it is known that wheels are mounted before and after the center portion of the board bottom surface so that the vehicle can travel using a pair of sticks.

However, in such a structure, the seat part and the protrusion part formed in the upper surface of the board are configured so that the user can sit still and use it, so that the user can only run at a relatively slow speed, and can not expect to run by a sense of speed or fast movement. The technique disclosed in Korean Utility Model Publication No. 90-20004 or Korean Utility Model Registration Publication No. 20-021936 can partially compensate for the horizontal state of the board by protruding rubber pieces mounted on both sides of the integrated wheel. When passing through a curved portion or a barrier of a road surface, there is a problem that causes a risk rather than an obstacle.

Therefore, the present applicant has developed a "wheeled sled" to solve the above problems and proposed as a registered utility model No. 20-0339041.

However, the above-mentioned registered utility model No. 20-0339041 refers to "a main body having recesses formed with a non-slip in the upper surface and receiving bodies formed in a row at the center of the bottom surface, and receiving grooves formed at the front and rear of the main body. A front wheel and a rear wheel which are installed to be detachable via a buffer means, an auxiliary wheel which is installed to be detachable via a cylindrical member in a receiving groove formed in the center between the front wheel and the rear wheel, and is mounted to the rear of the bottom of the main body.

The wire connected to the front end of the first rod and the protruding piece of the bracket may be wound around the roller mounted on the fixing piece.

A light emitting part is provided at the rear of the main body, and the light emitting part is composed of a light emitting element that operates according to a switch operation, and a battery mounted in a receiving groove of the main body to supply power to the light emitting element. The stick is composed of a first foam with a handle attached to the upper side, and a second foam that is slid into the first foam and a non-slip piece is formed on the lower side. The first and second foams are assembled by a sleeve. It is possible to adjust the length.

Therefore, regardless of the time and space at the same time, you can run the road surface by stirring the stick with both hands regardless of the season, and through such a run can give a great addition to the muscle development of the upper body and lower body of the user. At the same time, it can be used as a universal exercise equipment that can be enjoyed while riding, and it can operate the braking means through the pedal to perform speed and braking of the main body to some extent, and the driving state can be easily operated at night by the light emitting unit installed at the rear of the main body. I could confirm it.

However, this configuration is difficult to balance because the user has to stand on the upper surface of the body when riding the sleigh, as well as difficult to balance the force applied to the joints, feeling the pressure on the joints, etc., also need no cushioning means It is complicated, so the failure rate is high and the production cost of the product is increased. Also, since the wheel bodies (ie, the front wheel, the auxiliary wheel, and the rear wheel) are arranged in the center of the bottom of the main body, it is difficult to maintain the balance while driving. Of course, there is a case in which the occasional injury caused by falling to the side of the side during driving, in particular, because the braking device must be operated by the foot while balancing the body through the foot during driving, there was a problem that can not adjust the exact braking force.

The present invention has been devised to solve such problems in the related art, and has a low failure rate and manufacturing cost, is not restricted by time and space, and can stir a stick with both hands regardless of the season. Through this driving, the upper body of the user as well as the muscle development of the lower body can be used as a universal exercise equipment that can be enjoyed while riding at the same time, the height of the saddle is normally adjusted regardless of the user's body size Stir up the stick with both arms in the standing position, and if necessary, you can ride the sled freely even in a comfortable sitting position to improve the usability, and the braking means can be operated through the stick to speed and brake the body.

Referring to the effect of the present invention sled configured as described above are as follows.

First, the wheeled sled according to the present invention includes a main body 1, a front wheel 2, a rear wheel 3, and a pair of auxiliary wheels 4, a braking means 6 for applying a braking force to the rear wheel 3, typically As shown in FIG. 2, a pair of sticks 5 for driving the saddle 7 and the main body 1 to allow the user to ride a sleigh riding the sleigh while riding the stick with both arms is shown.

At this time, the main body 1 forms a concave groove 11 in which the anti-slip member 12 is installed on both sides of the upper surface, and a partition 13 is installed in the central portion of the concave groove 11, but the partition 13 ) Is installed inside the battery 81 and the light emitting unit driving means 82, the power switch 83 and the saddle mounting device 14 is installed outside the wire 63 of the braking means (6) Has a configuration in which a wire drawing hole 15 can be formed.

In addition, the front wheel (2) for adjusting the direction of the sled can be rotated in the left and right direction within the predetermined angle (X ⁰ ; for example, 135 degrees) in front of the bottom surface of the main body 1, and at the same time Unlike the front wheels 2, the rear wheels 3 are rotatably installed so as to be rotatable only in the front-rear direction at the rear of the bottom surface of the main body 1.

In addition, when the sled or the safety jaw is formed on the road surface while the main body 1 is prevented from falling to the left or the right side of the sled, the front wheel 2 is lifted, even if it is shaken from the road surface. A pair of auxiliary wheels (4) which are installed in contact with the to secure the driving stability in the left and right directions within a predetermined angle (Y ⁰ ; for example 90 degrees) at both sides of the bottom center of the main body 1 It is possible to rotate and at the same time to be rotated in the front and rear direction.

At this time, the diameter of the auxiliary wheel (4) has a slightly smaller diameter than the diameter of the front wheel (2) and rear wheel (3) so as to maintain a constant height (h) and the road surface on the flat road slightly Also, the middle part of the sled is supported so that the front wheel 2 or the rear wheel 3 installed in the front part or the rear part of the main body 1 may be prevented from deteriorating stability due to floating from the road surface.

On the other hand, the reason for limiting the left and right rotation angle (X ⁰ ) of the front wheel (2) to within 135 degrees to prevent the sled overturning due to a sudden change of direction while traveling along the road surface, the auxiliary wheel (4) The reason why the left and right rotation angle of Y ⁰ is limited to 90 degrees is to prevent the sled overturning due to the frictional force with the road surface, which may be caused by the angle of the auxiliary wheel 4 itself being converted to a right angle to the traveling direction. To do that.

In addition, inside the wheel of the front wheel 2, the rear wheel 3 and the auxiliary wheel 4 has a configuration in which the light emitting body 9 is provided as necessary. Thus, the front wheel 2, the rear wheel 3 and When the light emitting body 9 is installed inside the wheel of the auxiliary wheel 4, the light emitting body 9 installed inside the wheel blinks when each wheel rotates in response to the running speed of the sled, thereby providing a more beautiful visual effect. Can have

In addition, the pair of sticks 5, which allow the user to hold and hold in both hands and control the direction and speed of the main body 1, includes a first pole 52 having a handle 51 mounted on the upper side thereof, and the first one. It has a diameter smaller than its diameter so that it can be inserted into the pole 52, and at the same time the length of the second and second poles 53 and the first and second poles 52, 53, the anti-slip piece 55 is provided on the lower side The sleeve 51 for adjustment as well as the handle 51 formed on the stick 5 of one side, the user can pull or keep the wire 63 of the braking means 6 during the running of the sled. The lever 64 has a configuration engulfed through the hinge.

Therefore, the user unscrews the sleeve 54, removes or pushes the second pole 53 from the first pole 52, and then tightens the sleeve 54 again to fit his / her physical condition. ) Can be used after adjusting the length.

In addition, the handle 51 of the stick 5 is provided with a fixing band 56 made of a normal velcro tape, etc., so that the user's hand can be fixed on the handle 51 by using this to run the sled. When, for some reason, the stick 5 can be prevented from slipping off the hand.

Of course, one of the sticks 5 of the sticks 5 is provided with a lever 64 to which one end of the wire 63 of the braking means 6 is fixed. If you want to brake while riding on a sled while riding on the road or in the saddle (7), pull the lever 64 in the same manner as when braking a bicycle or a motorcycle. Compared with this, more accurate and safe braking force can be obtained.

On the other hand, the braking means 6 is provided with a guide plate 61 for supporting the wire 63 and the fixed plate 62 for fixing one end of the wire 63 in the front and rear portions of the rear wheel (3), The other end of the wire 63, one end of which is fixed to the fixing plate 62, is sticked through the rear wheel shaft 31 of the rear wheel 3, the wire drawing hole 15 of the guide plate 61, and the partition 13. It has a structure fixedly attached to the lever 64 provided in the one handle 51 of (5).

Therefore, although not illustrated in the ordinary case, the wire 63 itself is slightly sag due to the elasticity of the return spring provided at one end of the wire 63 and the hinge shaft of the lever 64 so that the wire 63 is slightly sag. Part of the rear wheel shaft 31 is kept apart and does not interfere with the running of the sled, but to operate the braking means 6 to brake the sled driving on the road surface, the user of the one side stick (5) When the wire 63 is pulled toward the lever 64 by pulling the lever 64 installed on the handle 51, a part of the wire 63 located on the rear wheel 3 side is slid to the rear wheel shaft 31. Since the friction force is generated, the speed of the sled is reduced or stopped according to the braking of the rear wheel (3).

At this time, the length of the wire 63 located between the wire drawing hole 15 of the partition 13 and the lever 64 provided in the handle 51 of the one side stick 5 is the length of the stick 5. The length of the wire drawing hole 15 itself is formed in the front part of the partition 13 located at the front part of the main body 1, and the wire of the lever 64 is made long enough so that it does not interfere with running the sled. The fixing part may be positioned inside the handle 51 so that the wire 63 itself does not get caught in the user's leg or the stick 5 when the sled is driven by using the stick 5 to stir the road surface. The length of the same wire 63 can be adjusted on the fixed plate 62 attached to the back.

In addition, since the wire 63 uses a flexible rigid wire formed by twisting a plurality of strands of very small diameters, the wire 63 may be large even when the wire 63 itself slides with the rear wheel shaft 31 during braking. Although not worn or damaged, if necessary, a separate friction member or strength reinforcement 631 may be provided outside the wire of the portion sliding with the rear wheel shaft 31.

On the other hand, the saddle (7) is detachably installed in the saddle mounting portion 14 of the main body (1) to allow the user to ride a sled is mounted to the bottom of the seat plate 71 that the user can sit The second pipe 73 is detachably installed at the saddle mounting portion 14 of the main body 1 while the upper part of the first pipe 72 and the upper part of the first pipe 72 are slid. And a sleeve 74 installed between the coupling portions of the first and second pipes 72 and 73 to adjust and fix the overall length of the first and second pipes 72 and 73. Consists of.

Accordingly, the user loosens the sleeve 74 like the stick 5 described above, removes or pushes the second pipe 73 out of the first pipe 72, and then tightens the sleeve 74 again. What is necessary is just to adjust the height of the saddle 7 suited to a physical condition.

At this time, the saddle mounting 14 may have any shape as long as the bottom end of the second pipe 73 can be detachably fixed. For example, the saddle mount 14 may be threaded outside the bottom end of the second pipe 73. And any fixture known in the art, such that the saddle mount 14 itself may have a nut shape, and may have a column or rod shape that can be fitted into or out of the second pipe 73. Irrelevant

In addition, the rear portion of the sled main body 1 of the present invention is provided with a light emitting portion 8, if necessary, inside and outside the partition 13, as described above, the battery 81 and the light emitting unit driving means, respectively. 82 and the power switch 83 are provided.

Therefore, when the user wants to ride the sled at night, the light emitting part 8 installed at the rear part of the main body 1 by the operation of turning on the power switch 83 is the It is controlled by lighting or flashing or sequential flashing.

Therefore, the driver of the vehicle, etc. located in the rear of the sled of the present invention can recognize the running state of the sled through the light generated from the light emitting unit 8 of the main body 1 and protect the person riding the sled.

In this case, the light emitting unit 8 may be formed of a general lamp, a light emitting diode, or the like. In addition, a luminous plate or the like may be attached to the rear or side surface of the main body 1 to further secure safety.

On the other hand, to transport or transport the saddle 7 in a state in which it is coupled to the main body 1, the overall volume is large, and the transport and transportability is not good, and the saddle 7 is separated from the main body 1 to carry or transport. In this case, the total volume can be reduced, but since they are separated from each other, the handling, transport and transportability are poor.

Therefore, in the present invention, the first and second pipes 72 and 73 of the saddle 7 separated from the main body 1 by installing at least one or more pairs of locking holes 10 at the front and rear of the upper surface of the main body 1. ) So as to be detachably coupled to the locking mechanism 10 to be fixed, handling and transport and transportability of the sled are very good.

Of course, since the belt-shaped handle 16 is installed on the front portion of the main body 1, the belt-shaped handle 16 attached to the front of the main body 1 when the sled is to be lifted and moved while traveling or needed. By using it, you can easily carry a sled.

Although the above-described embodiments are described with respect to the most preferred example of the present invention, it is not limited to the above embodiments, it is apparent to those skilled in the art that various modifications are possible without departing from the technical spirit of the present invention.

As described above, according to the present invention, since the configuration of the first parts is very simple, the failure rate and manufacturing cost can be reduced, and the second time is not limited by time and space, and at the same time, regardless of the season, it is possible to stick with both hands in a standing or sitting position. Stir to drive the road surface, and third can be used as a universal exercise equipment that can ride while enjoying a great addition to the user's upper body as well as lower body muscle development through such a run.

Fourth, you can ride the sled in a comfortable sitting position by adjusting the height of the saddle regardless of the body size of the user, and the usability can be improved through the fifth stick, and the speed and braking of the main body can be precisely adjusted. In addition, the light emitting part installed at the rear of the main body makes it easy to check the driving state at night, thereby ensuring safety. The light emitting elements installed at the seventh front wheel, the rear wheel, and the auxiliary wheel operate blinking while the sled is running. It is a very useful design that can be created beautifully.
