The present invention is equipped with an engine in a common cart, when the load is large or climbs hills, etc., the power is transferred to the wheels and can be easily climbed by the power of the power. It can be pulled by a person with the power of the same, such operation is made of the handle of both hands up and down of the cart, and relates to a cart consisting of an auxiliary power device that works together with the brake system.

In the conventional carts for transporting briquettes or trash, there is no such device, so when you go up the hill and load up the hill, you have to push up and pull from the front and back, so it is not only difficult but also requires a lot of manpower. In the case of a downhill road, there is no special brake system, so a few people must pull it from behind. Otherwise, if one person loads the luggage and descends dangerously, people are often injured. The present invention is devised to correct such drawbacks and is described in detail by the accompanying drawings as follows.

The clutch 24 and the bearing housing 25 are sequentially addressed to the rear of the pulley 23 fitted with the engine 22 mounted on the belt 22 connected to the front upper end of the cart 1 having the loading box 2. Propulsion shafts 27 coupled to the poly 23 on the center line thereof are formed long and are coupled to the differential gear device 28 formed at the center of the drive axles 26 of both wheels 32 and 32 '. And both sides of the support (4) (4 ') vertically formed to the front of the cart (1) is connected to the shaft pins (5) (5') and pivoting pieces (8) (9) rotated around the shaft is integrated The right handle 6 and the left handle 7 are also formed integrally, and the bottom of the rotation piece 8 of the right handle 6 forms an inclined surface 10 formed downward in the forward direction and the left handle 7 of The bottom of the rotating piece 9 forms a smooth bend portion 11 from the front side, and at one rear end thereof, a recess 12 is formed.

In addition, the hydraulic lifting bar 14 of the master cylinder 13 fixedly installed inside the support 4 is grounded with the lower inclined surface 10 of the pivoting piece 8, and the brake line 15 interlocked with the cart 1 ) Is connected to a braking device (not shown) in both wheels 32 and 32 'along the bottom guide groove 16, and also moves up and down around the pin 20 inside the support 4; The operation period 18 of the lever 17 is grounded to the bottom of the pivoting piece 9 of the left handle 7, and the clutch connecting cable 21 coupled to the interlocking rod 19 is the bottom guide groove of the cart 1. 16 ') is connected to the clutch 24. Reference numeral 29 in the drawing denotes a coupling hole, which is coupled to the iron ball 30 installed in the spring 31 in the support body 4, as shown in FIG. In the lower operation, the iron hole 30 is coupled to the coupling hole 29 to serve to fix the handles 6 and 7. Unexplained reference numeral 33 is the auxiliary transverse, (34) (34 ') is the reinforcement plate, (35) is 360 It is a horizontal wheel.

Referring to the effect of the present invention configured as described above are as follows. In Figs. 2 (a) and 2 (b), both handles 6 and 7 are horizontal, so the inclined surface 10 at the bottom of the pivoting pieces 8 and 9 of both handles 6 and 7 is horizontal. ) And the hydraulic lifting shaft bar 14 and the operation period 18 grounded at the orifice portion 11 are in a state in which no action is performed, and the master cylinder 13 is also released, and the clutch 24 is also in a flat state. If you load less, people are attracted to the manpower, and if you need to transfer power on a hill or a lot of load, as shown in Figures 3 (a) and 3 (b), 6) When the 7 is moved upward by about 15 °, the rotating pieces 8 and 9 are also rotated at the same time, but the moving pieces 8 of the right handle 6 are all inclined downwards 10 forward. Since the rotation piece 8 is rotated, the position does not change, and thus, the hydraulic lifting shaft bar 14 also does not change in its original position, so the master cylinder (13) has no effect, and the brake line 15 connected thereto continues to release the braking of both wheels 32 and 32 ', and the left handle 7 rotated simultaneously with the right handle 6 As shown in FIG. 3 (b), the turning piece 9 of the rotating member 9 enters the rear recess 12 as the operating part 18 of the operating lever 17 leaves the bottom orifice 11 of the rotating piece 9. do. Since this is a state where the clutch cable 21 is always pulled from the clutch 24, the operating period 18 moves upward while the operating period 18 reaches the groove 12 of the pivoting piece 9 while the groove 12 is moved upward. The clutch 24 is connected and the power transmitted from the engine 3 is transmitted to the pulley 23, the propulsion shaft 27 and the differential gear device 28 in a known manner. Both wheels 32 and 32 'are rotated by the power of the power, and thus can easily climb a hill or the like.

When the vehicle is to be stopped in progress, as shown in FIGS. 4 (a) and 4 (b), both handles 6 and 7 are about 15 in a horizontal state. 30 degrees down and upwards, with power being transmitted When the lowering degree is lowered, each rotating piece (8) (9) is also rotated, and the rotating piece (8) of the right handle (6) is formed on the inclined surface (10) with its bottom downwardly forward, and the rotating piece (8) is rotated. At the same time, the hydraulic lifting shaft bar 14 is pushed and lowered, thus actuating the master cylinder 13 by the pressure of the hydraulic lifting shaft bar 14 along the brake line 15 to the wheels 32, 32 '. Transmitted, the wheels 32 and 32 'are braked. That is, as described above, when the power is transmitted, both handles 6 and 7 When lowered to this degree, the brakes are applied to both the wheels 32 and 32 'by the pressure of the hydraulic lifting shaft 14 due to the rotation of the pivoting piece 8 of the right handle 6 and the wheels 32 and 32'. The wheelbarrow 1 is stopped and at the same time, the pivoting piece 9 of the left handle 7 is also rotated together. At this time, the operation lever 17 is operated in the recess 12 of the bottom of the pivoting piece 9. (18) is pinched and then out of the groove 12, the oral portion 11 reaches the operating period 18, and thus the operating period 18 is lowered around the pin 20, the orbiting portion (11) ) And the soft space 19 is raised while the clutch connection cable 21 connected thereto is pulled, the clutch 24 is dropped, and thus the power to the wheels 32 and 32 'is also cut off. In other words, this operation is performed at almost the same time. When both handles 6 and 7 are horizontal and power is not being transmitted and a person tries to stop the vehicle even when being pulled by manpower, the handles 6 and 7 are moved. 15 When it is lowered to the lower degree, the position of the actuating lever 17 does not change as shown in FIGS. 4 (a) and 4 (b) in the state of FIGS. 2 (a) and 2 (b) and the hydraulic lifting shaft bar ( Since only 14) descends, the handicraft (1) can be stopped.

As shown in FIGS. 2, 3 and 4, both handles 6 and 7 are rotated separately, and the coupling hole 29 formed at the lower end of the pivoting piece 8 and 9 is a support 4. 2) Both handles 6 and 7 are fixed at each operation while being engaged by the iron ball 30 in the spring 31 in the spring 31, and the auxiliary wheel 35 formed at the front lower portion of the cart 1 is the cart 1. In addition to keeping the body horizontal at all times, the auxiliary wheel (35) itself is also horizontally 360 Rotation is very easy by turning.

The present invention imposes a power unit on a conventional cart, so it can be used as a normal cart in normal times, and when it is loaded with a lot of load or climbs a hill, power can be immediately transmitted to the wheels to minimize the waste of manpower and the consumption of physical strength. It is an economical and useful design that can be reduced and suddenly stopped when obstacles appear.
