Description

This invention relates to a user-friendly, load-reducing manual trunk for transporting luggage during travel, etc. In conventional two-wheeled transport trunks, a portion of the weight load is always borne by the hand holding the handle or the removable manual handle. Furthermore, in conventional four-wheeled transport trunks, the manual handle, mounted on the long side of the trunk when viewed from above, is used by lifting it up as needed. However, when pulling the trunk from behind the body, the trunk tilts slightly in the direction of travel, increasing the weight load on the hand and causing significant wear on the two front wheels that contact the ground. To avoid this, the entire trunk is rotated 90 degrees, positioning the trunk and handles facing forward and backward at the side of the body. However, even on slightly uneven surfaces, the load on the palm holding the handle is not evenly distributed, leading to hand fatigue in a short time. Japanese Utility Model Publication No. 07-028425 A perspective view of the four-wheeled trunk of this invention with the carrying handle removed.This diagram shows the shape of the additional luggage support plate, which is stored in the inner pocket portion 15 of the trunk's opening surface 14 to support additional luggage on the top surface of the trunk. 10, 11, 12, and 13 are holes for passing belts through. Two grooves are cut to allow the manual handles 6a and 6b to fit snugly. The additional luggage support plate is secured with manual insertion and retaining screws, consisting of 16 and 17 in Figure 5.Figure 2 shows the shape of the additional luggage support plate when it is installed on the top surface of the trunk, as viewed from the side.A side view of the entire trunk when transporting additional luggage. This diagram shows how the additional luggage is secured to the transport handle and the additional luggage support plate at different positions using four belts 16, 17, 18, and 19 to ensure stable holding of the additional luggage.Fixing device for additional luggage indicator board to the trunk manual handle. It consists of a U-shaped plate 16 and a manual fixing bolt 17. The square 6 inside is the cross-section of the manual handle's rectangular rod.Belt-type anti-slip devices 21, 22 for the moving handle when supporting additional luggage.L-shaped corner reinforcing connecting plate to prevent trunk deformation when additional luggage or seats are used. Figure 1 shows the front view of the trunk when it is moving, the top view of the trunk when it is moving, the bottom view where the four wheels for movement are fixed, the side view for opening the trunk, the trunk handles (4 and 5), and a removable handle (6) from the 1a side. 7a, b, and c are three of the four wheels used for movement. The dashed lines represent the zippers for opening and closing the trunk. To accommodate additional luggage and seating, it is essential that the angle between the four cylindrical sides of the trunk (1a, 1b, 2a, and 2b, as shown in Figure 1) remains within approximately 1 degree of 90 degrees, even when a 100 kg load is applied to side 2a. Therefore, these four sides are constructed from lightweight yet strong aluminum plates of sufficient thickness, and the four two-sided connection points are reinforced with lightweight yet strong L-shaped connecting plates, as shown in Figure 7. By installing these aluminum L-shaped bars, several millimeters thick and approximately the length of the trunk, inside the trunk and securing the four sides to them with eight bolts each, additional luggage can be loaded without deformation of the narrow sides of the trunk, and a weight of 100 kg can be supported. This is crucial for ensuring the long lifespan of the trunk.
