Description of Invention (/) The amount of invention · This invention relates to a handcart or touch-wheeled cart for carrying a small load that is too heavy or too large and heavy . There are many different types of well-known trolleys or touch-wheeled trolleys. A conventional trolley or touch-wheeled trolley, such as a so-called bag-type stretcher trolley, includes an L-shaped frame with a pair of wheels at a right angle, and the wheels are pivoted on the frame. The staggered parts of the crossed arms. The horizontal arm portion is much shorter than the vertical arm portion, and the vertical arm portion has a pair of grips or a grip ring at an upper end portion thereof for controlling the stretcher trolley. The advantage of this stretcher trolley is that its carrying or unloading action is tilted in order to guide the platform formed by the horizontal arms of the L-shaped frame. In addition, most of the weight of the load is borne by the operator through the grip; in particular, if the frame is tilted at a considerable angle in the vertical direction during operation, and if the platform of the load is carried Placed on the ground, for example, to allow the operator to take a short break, this may cause the danger of falling and falling of his weight. The bag-type stretcher trolley is developed from British Patent No. 566,932, which discloses a touch-wheeled trolley with a pivotable secondary frame structure, and the secondary frame structure is provided with a special Under load, use the arm for meshing. French Patent No. 1,339,773 also describes another touch-wheeled cart for special load applications. In this patent, a frame for the installation of industrial gas cylinders can be combined by a hook on a main frame so that, like a bag-type stretcher trolley, the gas steel can be lifted to 4 paper sizes.

Description of Invention (>) Bottles are shipped in an inclined state. A double-frame trolley described in the European Patent No. 136571 of the applicant of the present invention can be used as a load-carrying touch-wheel trolley or stretcher-type trolley, which can overcome many shortcomings of the conventional bag-type stretcher-type trolleys. The characteristic is designed to carry the load in a vertical manner instead of the inclined way like a bag-type stretcher trolley, and it can stably rest on the ground and support the weight of the operator without the risk of overturning. In this trolley, the load is partially balanced around an axis (the wheel that touches the ground), and the lever on which the operator relies is low, so as long as the platform is placed horizontally, It can be controlled smoothly with a considerable load on it, and the operator does not need to exert a very large force. When the center of gravity of the load is higher than the height of the hinge connecting the two frames, if the frame that is part of the handle of the operator accidentally drags downward and goes beyond the height under normal operating conditions, There is danger, for example: if the operator falls or trips, the load may suddenly fall backward and reach the operator, and fall into a dangerous situation. The present invention is designed to solve this problem. SUMMARY OF THE INVENTION Accordingly, the present invention proposes a trolley for transporting a heavy load, which includes a main frame and an auxiliary frame. The main frame has a pair of grounding wheels rotatable about a first axis, and the The auxiliary frame carries a load-bearing mechanism that is connected to the main frame by a hub. The five-sheet scale applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm).

Description of the invention (,) and can be located at the first and second ends It is rotated relative to the load bearing mechanism around a second axis parallel to the first axis; there is a restraint mechanism which is used when the two frames are located at or near one of the end positions, One frame body restrains the associated rotational movement of one frame body in at least one direction relative to the other frame body. The orientation of the load bearing mechanism at the first end position is parallel to and in contact with the ground, and is moved to the front of the wheel; and when the load bearing mechanism is at the second end position, At least a portion is displaced behind the wheel. Therefore, a feature of the present invention is that the related rotational movement between the main frame and the auxiliary frame can be restricted by a restraint mechanism in order to determine the first or the first of the auxiliary frame with respect to the main frame. Two end positions. In a preferred embodiment, the restraint mechanism acts on or near the second end portion. The restraint mechanism can be selectively combined or automatically combined. The restraint mechanism is detachable. The restraint mechanism includes an engaging mechanism on a frame body that can be combined with a combination member or on a member carried by another frame body. In a preferred embodiment, the restraint mechanism includes a removable self-engaging latch. The latch system can be biased elastically into an engaged position. Other forms of restraint mechanism may include a rotatable or fixed wedge member mounted on one of the two frames, the wedge member is arranged adjacent to 6 paper standards applicable to China National Standard (CNS) A4 specifications ( 210 X 297 mm) -2 --------- Order --------- line (please read the notes on the back before filling this page) 517026 A7 B7 V. Description of the invention (+ ) At the pivot point between the two frames. The wedging member can be placed between the two frames to prevent further rotational movement between the two frames. Alternatively, a latch such as a manual type may be used so as to restrict the restraint mechanism by acting on the opposite end portion of the above-mentioned locking member. This mechanism extends between the main and auxiliary frames and presents a substantially rigid rod that can be connected to fix the main and auxiliary frames and set them in corresponding positions. When in use, the position of the first end of the load bearing platform of the auxiliary frame can be placed in contact with the ground; in this case, the main frame is translated from the second relative position to the first relative position Movement in any way in the direction can be prevented by this abutting form, and the force acting on the main frame can be transmitted to the ground through the auxiliary frame. In this situation, the line of force on the handle and passing through any point of the load platform will apply a turning moment about the second axis to promote the auxiliary frame to the main frame relative to the main frame. The first relative position of the second frame. The main frame may include an axle member connecting two ground wheels of the main frame. If the axle member is used, and the restraint member is not combined due to the failure of the mechanism or the decision not to engage with the restraint mechanism, the axle member may also constitute a close frame that allows the auxiliary frame to lean against it. The restraining member determines the position of the second end of the auxiliary frame relative to the main frame, and the axle member is generally U-shaped and has two free ends connected to the side members of the main frame respectively.

Description of the invention u) The top of the auxiliary frame is a first lateral bracket 29 with two pins 29a and 29b. Load a restraint chain 30 or similar flexible linear member that can be used to securely restrain a load from positioning. Two L-shaped fixing members 31a and 31b are provided on both sides of the auxiliary frame and at the same height as the first transverse bracket 29, and the fixing members can be used as additional equipment for supporting a gas cylinder hose, for example. A second lateral bracket 32 is provided on the auxiliary frame body 26 and is located just above the elbows 27a and 27b. The first and second lateral brackets 29 and 32 help to increase the rigidity of the auxiliary frame and can be used as a support for the load. The bottom ends of the lower sides 26a and 26b of the auxiliary frame are extended to form a load bearing mechanism and are generally designated by reference numeral 28. The connection between the arms 26a and 26b on the bottom side of the auxiliary frame body and the load bearing mechanism 28 can be achieved by any convenient method such as welding or bolting; and, this method can be more on the plane of the bottom of the platform A predetermined fixed angle is taken with the side arm portions 26a and 26b at the bottom of the auxiliary frame body to obtain a strong connection, and it can be strengthened by combining the two support frames 34a and 34b. Alternatively, the load bearing mechanism 28 may constitute a part of the auxiliary frame. In this embodiment, the load bearing mechanism 28 is formed as a U-shaped frame having a curved portion 28a and two substantially parallel arm portions 28b and 28c. The load-bearing slender rod 35 straddles the substantially parallel arms 28b and 28c to form a platform for receiving a load. The auxiliary frame 26 is restricted by the restraint mechanism (generally designated as 33) and is restricted by the pivot frame axis χ_χ with respect to the main frame 12. 11 This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (Please read the notes on the back before filling out this page) · Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Online Economics 517026 A7 B7 V. Description of Invention (q) The pivot movement will refer to sections 2, 3 and 4 Figures are described below. Referring first to Fig. 2, it is shown that the touch-wheeled trolley is at a first end position, and the load-carrying mechanism 28 is flat on the ground surface. In this position, the main frame 12 is rotated around the pivot axis XX in the counterclockwise direction as seen in FIG. 2 to the maximum extent; the arms 13 and 14 of the main frame 12 are tied to the wheel 16 While still in contact with the ground, 17 and 17 rotate around the pivot axis XX until the load bearing mechanism lies on the ground surface. The main frame is juxtaposed with the upper portions of the auxiliary frames 12 and 26; and there is no longer any rotation of the main frame 12. No matter in the case where the action line passes downward force behind the pivot axis XX, or in the case where the action line passes forward through the axis XX force, due to the low side arm portions 13 and 14 of the main frame and the auxiliary frame Amplifying effect of the body 26, so any load acting downward on the handle 21 will cause counterclockwise torque of the auxiliary frame 26, because this situation will also pass through the load bearing mechanism 28, so it will be pushed To the ground and rotate the main frame 12 in a counterclockwise direction. The position printed in Figure 3 by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is achieved by dragging the handle 21 downward to lift the load bearing mechanism 28 from the ground, which is shown in Figures 2 and 3 The view is displayed to the right. This situation has the effect of rotating the main frame body 12 about the pivot axis X-X until the restraint mechanism (identified generally by the reference numeral 33) further prevents it from rotating. From the situation where the position shown in the second figure is reached to the position shown in the third figure, it can be seen that the load bearing mechanism 28 does not undergo an actual tilting action. 12 This paper size is in accordance with Chinese National Standard (CNS) A4 (210 > < 297 mm) 517026 A7 B7 V. Description of the invention (p) Because the main frame I2 is bent and connected to the elbow 19 and 20 Therefore, the distance between the position of the handle 21 and the vertical center line passing through the wheels 16 and Π is much larger than the distance between the center of gravity of the platform 27 and the center of gravity. Therefore, even if there is a heavy load on the load-carrying mechanism 28 ', the above-mentioned lever action is a great advantage to the person who controls the trolley on the operation of the machine. As can be seen from Fig. 3, the load 29 can be carried completely vertically by the force acting on the grip 21 to balance its weight. The weight of the load 29 is actually partially balanced by the platform 27 extending slightly to the rear side of the common axis of the wheels, thus reducing the force required to apply to the grip 21 by a quarter to a third. One can easily handle heavier loads; however, if the platform does not extend beyond the axis of the wheel, the aforementioned forces are necessary. The operation of the restraint mechanism 33 will be described in more detail below with reference to FIG. 4. The restraint mechanism includes a latch member 50 and an engaging member 60. The employee member cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed the latch member 50 to be pivotally connected to the side arm portion 14 below the main frame at a pivot point 53. Office. The engaging member 60 is substantially a C-shaped member, which is located on the side arm portion 26b below the auxiliary frame body and is opposed to the latch member 50 ·. The latch member 50 is an elongated member that is substantially like a lever and has a lateral indentation 51 adjacent to a head-like portion 52. The head-shaped portion 52 has a curved side wall adjacent to the mouth of the dent 51, and this shape is in the form of a hand. 13 The paper size is applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm). --- 517026 A7 B7 V. Description of the invention ((丨) When the cart is pushed to reach the second end position shown in FIG. 3 from the first end position as shown in FIG. 2 and is combined with the engaging member 60 Can act as a cam surface. This situation causes the latch member 50 to rotate (toward the clockwise direction indicated by the drawing) the pivot point 53 so that the mouth of the dent 51 and the The engaging member 60 is aligned, and at the same time, the latching member 50 is combined with the engaging member 60. The latching member 50 is elastically biased by an elastic member 51 connected to the latching member 50 at a position relative to the head portion 52. At the point upstream of the pivot point 53. The other end of the elastic member is connected to a pin 55 on the side arm portion 14 below the main frame. The elastic member 54 can be made into a tension spring and torsion Spring or reed spring. At the closed position, it is mainly locked and fixed with the auxiliary frames 12 and 26, so that in any case, if the handle 21 is dragged down to the ground to carry a load 29 with a high center of gravity position, Then the auxiliary frame 26 cannot reach the main frame 12 by the upper end of the auxiliary frame 26, so the danger of the load 29 overturning to the operator can be avoided. In the embodiment shown in FIGS. 5 and 6 The method of operation is the same as in the first embodiment: that is, the main and auxiliary frame systems are moved between the first and second end positions as shown in Figures 5 and 6. In this embodiment, the main frame 12 has a more protruding loop 36 ′, and when the main frame 12 is at the second end position, the loop is adapted to the Chinese national standard by 14 paper sizes (CNS) A4 specification (210 X 297 mm) (Please read the precautions on the back before filling out this page} Γ Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs's Consumer Cooperatives 517026 Α7 Β7 5.
