Preferably, the transport box 10 includes two wheels on opposite sides of the wide (back) bottom edge of the transport box. The transport box 10 also preferably includes an adjustable handle system 11. Also shown in the figure is the main box, which has a back 20 or back, a front surface 26, and a pull tab 30 for providing access to the main box of the transport box. The adjustable handle system 11 preferably comprises an extendable and retractable vertical element 15 having a horizontal portion 16 on its top and a handle 13 pivotally connected to the horizontal portion 16, wherein the handle 13 is selectively pivoted about the horizontal portion 16 and is selectively locked in at least one of a plurality of positions, which will be illustrated in other figures. Reference is made to the embodiment of FIGS. 1 to 9 'The extendable and retractable element preferably has first and second pituitary elements 15 and the horizontal portion 16 is a horizontal element connected to the first Between the tops of the first and second vertical elements 15. The first and second vertical elements are preferably two nested elements. The extendable and retractable element basically forms a substantially "U-shaped" rod, although the present invention should not be limited to 9 paper sizes that are applicable to Chinese National Standard (CNS) A4 specifications (210 X 297 mm) " '------------ SK -------- Order ---------- Line · (Please read the notes on the back before filling this page) 537875 A7 ____B7_____ 5. Description of the invention (1) This shape is related to the embodiment shown in FIG. 9 to FIG. 11. The handle 1 3 can also be constructed as a U-shaped element, such as the part 1 8 of the handle 1 3. In addition, the handle 13 may further include a grip lever 19 'to which it is attached and extends from the U-shaped portion 18. The handle 13 is preferably smaller than the extendable and retractable element 15 'and is free to pivot within the range of the extendable and retractable element. Thus 'when the handle is positioned in a position parallel to the extendable and retractable element' the extendable and retractable element 15 and the pivoting handle 13 are simultaneously ideally fitted in a storage area or recess 2 5 in the retracted position. In operation, the adjustable handle system 11 will typically be located in a retracted position, as shown in FIG. 2, and is basically pressed to remain in the retracted position until pulled up, as shown in FIG. 3. . The two "handles" will ideally be arranged in parallel and housed in the notch 25. The notch 25 is preferably located in a recessed area having opposing recessed areas 21 and 23, as shown in the figure, to allow simple access to the "handle". The notch 25 may also include a plastic cover around the top of the notch, which allows the handle to be extended and retracted, and prevents the intrusion of dust and possible liquids. Once the handle is pulled up, as shown in Fig. 3, the vertical element 15 will remain positioned at a set height under tension or by some other suitable position setting mechanism. The adjustable handle further preferably includes a locking mechanism having a button on a portion of the handle to allow a user to selectively lock the handle in any of a plurality of positions. In. In Figure 3, the locking mechanism is a button 2 7 on the horizontal position to allow the user to selectively apply 10 paper sizes to the Chinese National Standard (CNS) A4 (210 X 297 mm)- ------------------- Order --------- Line 4 ^ (Please read the notes on the back before filling this page) A7 537875 _._ B7_ 5. Description of the invention (?) The handle 13 is locked in any one of a plurality of positions. Alternatively, the locking mechanism shown in FIG. 4 is a button 3 1 ′, which is located on the gripping lever 19 extending from the U-shaped portion 18. In addition, the gripping lever 19 may have a gripping region 29 which is formed ergonomically for most hands. In an embodiment, when the handle is pivoted about the contact 33, as shown in FIGS. 4 and 7, the user may selectively lock the handle in one of three positions. . Referring to FIG. 9 and FIG. 10, an alternative adjustable handle system 50 is shown for a transport case 52 (partially shown). The system 50 preferably includes an extendable and retractable vertical member 56 having a horizontal portion 57 in the top portion of the vertical member. The system 50 further includes a handle 5 8 pivotally coupled to the horizontal portion 5 7, wherein the handle is selectively pivoted about the horizontal portion and selectively locked in at least one of a plurality of positions . In this embodiment, instead of using two vertical elements, one vertical element is used. In addition, a recessed area 5 9 substantially in the shape of the handle 58 is formed on the outside of the vertical member 56 to allow the handle 5 8 to be stored in the recessed area 59. This allows the vertical element 56 and the handle 5 8 to be stored in a recess 6 4 in the retracted position. Similarly, referring to FIG. 11, another alternative adjustable handle system 60 0 is shown for a transport case 62 (partially shown). The system 60 preferably comprises an extendable and retractable vertical element 66 with a horizontal portion 67 in the top portion of the vertical element. The system 6 〇 further includes a handle 6 8 which is pivotally connected to the horizontal portion 6 7 and its 11 paper sizes apply the Chinese National Standard (CNS) A4 (210 X 297 mm) (please read the precautions on the back first) Fill out this page again) Order --------- line 537875 A7 _______B7_ 5. In the description of the invention (1), the handle is selectively pivoted around the horizontal part and selectively locked in a plurality of positions. In at least one position. The handle in this embodiment is similar to the handles 13 of the previous embodiments in Figs. As in the previous embodiment, instead of using two vertical elements, one vertical element is used. In addition, a recessed area 6 9 substantially in the shape of the handle 68 is formed on the outside of the vertical element 66 to allow the handle 6 8 to be stored in the recessed area 69. This allows the vertical element 66 and the handle 6 8 to be stored in a recess 6 4 in the retracted position. At the ideal angle, the transport case will be balanced on two wheels, with only minor vertical support provided by the user on the handle. Therefore, when it is being towed, the holding height of the hand (the distance from the floor to the handle grip while walking) should make the box almost balanced on the wheels, while the user provides a small amount during pulling Upward power. This height can be finely adjusted using the pivoting handle 1 3 in FIG. 1 or the handle 5 8 in FIG. 10 or the handle 6 8 in FIG. 11. This will allow the ideal angle to be used to tow the transport box, keeping it balanced. In general, I like the wheel handle as long as possible. A long wheel handle, which is the same for everything else, provides maximum leverage to support and balance luggage load. Moreover, a long arm helps the wheel box to be spaced from the user's feet so that the user can take a long walk without giving the heel to the box being pulled. The pivoting handle of the present invention further provides additional extensibility to the length of a generally single u-shaped handle, which in many cases is constructed to form two or more nested sections to reduce its storage height. 12 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before filling this page) -------- Order -------- -Line · 537875 A7 B7 V.
