The present invention relates to a brake device for a cart. Conventionally, there is no braking device applied to the cart itself, and the risk of causing fatal injury to the driver has always been accompanied by the weight of the load loaded on the cart, especially when going up or down a slope.

The present invention was devised to remove the risk of such an accident by installing a braking device suitable for such a conventional cart, and the basic concept of the braking device of the present invention is to provide braking, such as a non-motorized two-wheeled vehicle and a motorcycle, which have been conventionally used. When the brake liner is pulled and the braking control line connected to the handle is pulled and the brake liner is attached to the inside of the wheel by the series of devices attached to the braking control line. When the operator pulls the manipulator and puts the brake fastener on the handle immediately when the weight of the baggage loaded on the cart or a sudden danger occurs, the brakeliner adheres to the inside of the wheel's lime to apply braking. When described in detail based on the accompanying drawings as follows: The. That is, in the braking device of the present invention, two braking devices of the present invention, as shown in FIG. 2 of the accompanying drawings, are formed in one set and applied to one wheel of the cart, one of which is on the inner side of the wheel, and the other is Braking device of the present invention as described above, since the wheels of the wheelbarrow have two wheels, which are used by attaching a part of the outer casing 15 of the present invention to the vehicle body of the wheelbarrow at a predetermined interval on the outer side of the wheel. Since two are used in one wheel, four are used as a whole, and the two braking lines 18 used for the one wheel are attached to the brake fastening manipulator by fixing and fixing one again at a predetermined position. Referring to the configuration of the braking device which is the main part of the present invention in view of this point, as shown in the accompanying drawings 1 to 4, the brake linings 14 and 14 'are provided with respective brake plates ( 9) (9 ') is integrally fixed by a fastener (not shown), and the brackets 13, 13' are fixed to one end of the brake plate 9, 9 ', respectively, and a triangular upper end. Adhesion holes 8 and 8 'bored in reinforcement plates 6 and 6' of inverted triangles each having recesses 17 and 17 'and ball bearings 7 and 7' formed in the center. Reinforcement plates 6 and 6 'are secured by reinforcing rods 16, respectively, by means of a movable rivet ball (not shown).

Meanwhile, needle bearings 1 and 1 'are mounted on the triangular recesses 17 and 17' formed at the upper ends of the reinforcement plates 6 and 6 ', respectively. ) Is reciprocating along both sides of the triangular recess (17) (17 ') and the bearing shaft (2) is fixed to the inner circumference of the needle bearing (1) (1') and the spring support (4) The reciprocating section 3 of the rectangular pillar body with) is fixed and penetrated through the rectangular guide hole 12 drilled in the center of the fixing table 11 where the fixing shaft 10 is formed above and below, respectively. And a highly elastic compression spring 5 is built in the lower portion of the reciprocating section 3 between the spring support 4 of the reciprocating section 3 and the reciprocating section 3 by the elastic force of the compression spring 5. ) Is reciprocating between the guide hole 12, the both fixed shaft 10 is condensed in the state penetrated through the ball bearing (7) (7 ') installed in the reinforcement plate (6) (6') Amount of outer casing (15) The braking line 18 is fixed to the end of the brake line 18 at the end thereof while being fixed to the surface and penetrating the guide hole 15 'which is also drilled in the side surface of the outer casing 15 of the reciprocating section 3. ) Is a structure in which a conventional non-motorized power source formed on a trolley handle is fixed to a fastening operator used in a motorcycle or a motorcycle, as described above, and the holder 11 is a bowl bearing formed on a reinforcing plate 6 (6 '). 7) (7 ') can be left and right flow, and the reciprocating section (3) penetrated through the guide hole 12 is also possible to flow left and right, so that the reinforcement plate (6) (6') is also a ball bearing (7) ( The fixed shaft 10 inserted into 7 ') is used as a vertex to allow left and right flow.

The operation and the effects of the present invention configured as described above will be described in detail with reference to FIGS. 3 and 5 to 8.

In other words, while driving the cart, the braking line 18 fixed to the pulley is pulled because the driver is pulling the conventional fastening manipulator attached to the handle by the driver. Since the reciprocating section 3 is pulled back, the fixing table 11 is fixed to the outer casing 15 so that the spring support 4 of the reciprocating section 3 compresses the compression spring 5 so that the reciprocating section 3 The bearing shaft 2 and the needle bearing 1, 1 'fixed to the end of the liver 3 are respectively formed of the triangular recesses 17, 17' formed at the upper end of the reinforcement plate 6, 6 '. Since the reinforcing plate 6, 6 'itself does not flow from side to side by being inserted into a triangular groove, the brake plates 9, 9' and brake lining adhered to the reinforcing plate 6, 6 '. 14) (14 ') are also shown with only a few, but are operated at regular intervals (l) on the wheels 19 of the wheelbarrow.

In such a state in which the braking needs to be applied or there is an urgent situation, when the fastening control device including the handle and the braking line 18 is released, the compression contracted between the holder 11 and the spring support 4 is applied. The reciprocating section 3 is also upward by the springing force of the spring 5, so that the needle bearings 1 and 1, which are fitted in the triangular grooves of the triangular recesses 17 and 17 'of the reinforcement plate 6, 6', are mounted. ') And the bearing shaft (2) is upward, so that the reinforcing plate (6) (6') is left and right flows with the fixed shaft (10) penetrated through the bowl bearing (7) (7 ') formed thereon as a vertex. If the direction of rotation of the wheel is rotating to the left as shown by the arrow in FIG. 5, the reinforcement plates 6 and 6 'are also inclined to the same direction, that is to the left, according to the direction of rotation of the wheel. Brake plate 9 'and brakes adhering to the opposite side, i.e. right end of reinforcement plate 6, 6' Since the eclining 14 'is also inclined upward to the left side of the reinforcing plates 6 and 6', the surface of the lime 19 is brought into contact with the end thereof as indicated by the dashed line in FIG. The entire upper surface of the brake lining 14 'is removed while the other end is also rotated upward by the rotational force that is rotated to the left side of the lime 19 again around the hole of the coalescing hole 8 and the bracket 13'. As shown in FIG. 6 in the solid line on the outer surface of the crankshaft, it is braked by the elastic force of the compression spring 5 so that the cart no longer moves, and in this state, the reinforcement plate 6 (6 ') The right side of the triangular recess 17, 17 ′ formed on the upper side of the c) is in contact with the needle bearing 1, 1 ′ and is braking in a state in which it no longer flows to the left.

In this way, when the braking line attached to the handle is pulled while the braking is applied, i.e., in the state shown in solid line in FIG. 2) the needle bearings (1) and (1 '), which were in contact with the right side of the triangular recesses (17) and (17'), also carry the rolling motion along the right side of the triangular recesses (17) and (17 '). Gradually moving the reinforcement plate 6, 6 ', the brake plates 9, 9' and the brake lining 14, 14 'adhered thereto to the original position, and then the triangular recess 17 The reinforcement plates 6 and 6 'are no longer flowing from side to side, and the brake plates 9 and 9' and the brake linings 14 and 14 'are also attached to the triangular groove of the 17'). At a certain interval from 19), the braking is released as indicated by the dashed line in the original position, that is, in FIG. The vehicle is free to operate.

When it is necessary to brake in a state in which the driving direction is reversed, that is, in a state where the rotation direction is changed to the right in such a state in which it is possible to operate, when the braking line 18 is connected in the same manner as described above, the fixing table ( 11) and the reciprocating section 3 is also upward due to the impact of the compression spring 5 contracted between the spring support 4 and the triangular recesses 17, 17 'of the reinforcement plate 6, 6'. Needle bearings (1) (1 ') and bearing shaft (2), which were fitted in the triangular grooves of the rollers, are raised so that the reinforcing plates (6) and (6') penetrate through the bowl bearings (7) (7 ') formed therein. The left and right flows with the fixed shaft 10 as a vertex. At this time, the reinforcement plates 6 and 6 'are also inclined in the same direction along the rotation direction (right turn) of the wheel, that is, the opposite side of the rotation direction, that is, the reinforcement plate 6 ( Brake plate 9 and brake lining 14 adhered to the left end of 6 ') are also As it is upwardly tilted to the right, as shown by the dashed-dotted line in FIG. 7, the tip thereof is in contact with the surface of the lime 19, and again the center of the hole of the coalescing hole 8 and the bracket 13 is again. While the other end is also rotated upward by the rotational force of the rear rotation of the lime 19, the entire upper surface of the brake lining 14 is adhered to the outer surface of the lime 19 while being compressed as shown in FIG. 8 by the solid line. Braking is engaged by the spring force of the spring 5 so that the cart no longer moves. In this state, the left side of the triangular recesses 17, 17 'formed on the upper part of the reinforcement plate 6, 6' is the knee. These bearings (1) (1 ') are brought into contact with each other so that they no longer flow to the left and are braked.

In this way, when the braking is applied, that is, the state of the state shown in solid line in FIG. Needle bearing (1) (1 '), which was in contact with the left side of the triangular recess (17) (17'), is also rolling along the left side of the triangular recess (17) (17 '). Slowly move the reinforcement plate 6, 6 'and the brake plate 9, 9' and the brake lining 14, 14 'adhered to it to the original position and then the triangular recess 17, 17 ') The reinforcing plates 6, 6' no longer flow from side to side, and the brake plates 9, 9 'and brake linings 14, 14' adhered thereto, At a certain distance from 19), the braking is released as indicated by the dashed-dotted line in the original position, that is, in FIG. The station is available.

Although the operation of the present invention has been described above, in the braking device of the present invention, as described above, the two devices are one set, and the outer casing is applied to the vehicle body of the cart at regular intervals on the limb 19 of one wheel. Part of (15) is fastened and used.

Of course, in the above description of the present invention, the surface of the brake linings 14 and 14 'has been described as being in a planar state, but the wheel 19 of the cart itself is formed in a circle, so the lime 19 is also a circle. According to the inclination, the size of the brake linings 14 and 14 'of the braking device and the inclination of the surface may be changed and manufactured according to the inclination of the lime 19.

As such, the braking device of the present invention is applied to a cart that is not currently equipped with a braking device, so when climbing or descending a slope, the weight of the baggage loaded on the cart is automatically lost even if the user loses his mind or releases the handle momentarily. Since the braking device is fastened, the cart can be operated more safely, and the braking line 18 is fixed to the brake hydraulic cylinder shaft of a motorcycle or a motor vehicle using the engine of the present invention by fixing the braking line 18 of the disc under the driver's seat. It is obvious that this is a very useful design that allows the driver to apply the brake immediately when the driver falls off from the driver's seat due to the instantaneous breakdown with the brake fastener.
