Description

Folding wagon {FOLDING WAGON}

The present invention relates to a folding wagon, and in more detail, it can be used as a multi-purpose transport tool, and it is convenient to use such as carrying luggage or cargo. It relates to a folding wagon that prevents unexpected accidents.

In general, a wagon is a transport tool used to load and transport goods. However, in recent years, it is also used as a means of transport for moving infants comfortably.

A number of supports are provided on the body to support the items loaded in the conventional wagon, and a loading compartment is formed. .

However, these traditional wagons were focused only on the movement of heavy loads, and accordingly, there were several shortcomings in the use of moving infants, which is a recent use.

In order to be used as a wagon for infants, it needs to be made in a foldable form for ease of use at home, and since it is a child riding it, there must be a safety device for the safety of the child, but the existing wagon lacks such a part.

Referring to FIGS. 4 and 6 , the first rotating device 810 rotates repeatedly in a predetermined angular range in the AA′ direction. Accordingly, the sliding member 820 moves in the connecting member 730 while the connecting member 730 linearly moves in the BB' direction (ie, the front-rear direction of the wagon 1). At this time, since the distance between the first rotating device 810 and the connecting member 730 is continuously changed, the force transmitting means 811 connecting the first rotating device 810 and the sliding member 820 has a variable length. .

7 to 9 show a state in which the support part 900 of the present invention is used.

In the folding wagon 1 according to another embodiment of the present invention, a second main bracket (B2) for coupling the lower ends of the front vertical frame 110 and the rear vertical frame 210 and the link frame 300 to each other. and a support part 900 formed on the upper end of the second main bracket B2 and extending toward the plate part 700 to support the plate part 700 from below.

In the folding wagon 1 according to another embodiment of the present invention, the support structure 910 supports the bottom of the plate part 700 when the plate part 700 is fixed, and the plate part 700 moves the pendulum. A second support structure 910 that supports the link frame 300, which supports the link frame 300, and is fixed to the upper end of the second main bracket B2 so that the support structure 910 is rotatable. A rotating device 920 may be included.

As can be seen in Figures 1 and 4, the link frame 300 of the present invention has an upper and lower link frame, and forms both sides in an 'X' shape. Therefore, the link frame 300 is not coupled only to the upper end of the vertical frame 110;210, but the link frame 300 should also be coupled to the lower end of the vertical frame 110;210. The second main bracket B2 couples the link frame 300 and the lower ends of the vertical frames 110 and 210 to each other.

Referring to FIG. 7 , the support part 900 may be disposed on the upper end of the second main bracket B2 . The support part 900 serves to support the plate part 700 . When the plate structure 710 of the plate part 700 makes pendulum motion, the support part 900 is separated from the plate part 700 . When the plate structure 710 does not move forward, the support part 900 supports the bottom of the plate structure 710 .

The support unit 900 may include a support structure 910 and a second rotation device 920 . Referring to FIG. 9 , the second rotating device 920 may be disposed to surround the vertical frames 110 ; 210 , and the support structure 910 may have a shape extending outwardly from the second rotating device 920 . have.

The support structure 910 may serve two functions. First, when the plate portion 700 is in a fixed state, the bottom surface of the plate structure 710 is supported to ensure structural stability. Second, when the plate part 700 makes pendulum motion, the support structure 910 rotates in the AA' direction to support the link frame 300 . That is, the support structure 910 can rotate as shown in FIG. 8, and thus can perform two functions. The length of the support structure 910 can be variably changed, so that it extends to the maximum length when supporting the bottom surface of the plate structure 710 , and contracts when supporting the link frame 300 . Therefore, since the support structure 910 is contracted, it is possible to press the force in the direction of pushing the link frame 300 . Accordingly, even when the plate structure 710 makes a pendulum motion and applies a force to the structure of the wagon 1, the stability of the structure of the wagon 1 is secured by the force of the support structure 910 pushing the link frame 300 . . A member having an outwardly expanding force, such as a spring member, may be secured inside the support structure 910 , and the support structure 910 may press the link frame 300 by the expansion force of the spring member.

The second rotating device 920 allows the support structure 910 to rotate as shown in FIG. 8 . The second rotating device 920 is mounted on the vertical frame 110;210, and is fixed to the upper end of the second main bracket B2. The second rotating device 920 may have a rail formed therein so as to artificially rotate the supporting structure 910 , and there is a motor inside the second rotating device 920 to electrically rotate the supporting structure 910 . Of course it can be moved.

7, the length of the rear vertical frame of the present invention is expressed as a, and the height of the support part 900 is expressed as b. Due to the structural characteristics of the plate structure 710 of the present invention, the weight of the first coupling plate in the rear direction of the plate structure 710 is the heaviest, and accordingly, the second bottom of the rear vertical frame 210 of the wagon 1 Stress builds up on the main bracket (B2). That is, when the plate part 700 makes pendulum motion, a rotational moment due to the weight of the plate part 700 is generated in the second main bracket (B2), so that a shear stress is generated in the second main bracket (B2). do. Accordingly, in order to prevent cracks from occurring in the second main bracket (B2), the height of the support part (900) is formed to be higher than a certain height, and it is necessary to distribute the stress applied to the second main bracket (B2). In this case, b/a may be formed in a range of 0.1 to 0.3. When b/a is greater than 0.3, the height of the plate part 700 supported by the support part 900 becomes too high, and the length of the connection member 730 becomes too short, so the plate part 700 makes a pendulum motion to the cradle. Since the effect of is not easy to come out, b/a is formed to be 0.3 or less. When b/a is less than 0.1, the height of the support part 900 is too low to effectively disperse the stress generated in the second main bracket B2. Accordingly, b/a may be 0.1 or more and 0.3 or less, and most preferably b/a may be 0.2.

Although the present invention has been described in detail through specific examples, this is for the purpose of describing the present invention in detail, and the present invention is not limited thereto, and by those of ordinary skill in the art within the technical spirit of the present invention It will be clear that the transformation or improvement is possible.
