Description

  The present invention relates to a suitcase pulling rod gripping portion structure that has an annular shape and has a rotation adjusting function.

  FIG. 1 shows a handle structure 10 of a conventional suitcase pull bar. In this handle structure 10, an outer tube 11 and an inner tube 12 whose two sides are symmetrical are covered with each other to form an expandable rod structure, and the ends of the two inner tubes 12 are connected to the lower assembly member 13. The lower assembly member 13 and the upper assembly member 14 are joined to each other, and an expansion rod positioning mechanism (not shown) controlled by a button 15 is provided inside the two members. The assembly member 14 and the button 15 constitute a complete gripping part, and the suitcase is controlled using the gripping part.

At present, a structure form suitable for ergonomics is installed in a grip portion of many suitcase pull bars, and a user controls the grip portion by hand. However, in the conventional gripping part structure 10, the part of the gripping part is constituted by the lower assembly member 13 and the upper assembly member 14, and the lower assembly member 13 and the upper assembly member 14 generally have a “one” shape, and the lower part A fixed non-rotating grip shape is formed by connecting both ends of the assembly member 13 and the two inner pipes 12. For this reason, the center of gravity becomes unstable when the suitcase is too heavy, the pull rod is difficult to push, the tire does not rotate, and the user has to control the direction of the suitcase with force.
As in the actual use state of the suitcase pulling rod gripping portion structure 10 shown in FIG. 1, the user must hold the hand in a form that fits the suitcase pulling rod. This is because the ergonomic design of the gripping portion is This indicates that the user is not suitable for the operation that is operated by hand, and the hand and the ergonomic design structure are not in close contact with each other in the various operations of pushing and pulling the suitcase. The effects of mechanical design have not been demonstrated.

  In addition, when controlling the suitcase, the arm posture must be changed, and the muscle group function when bending the finger changes the force that enters the finger as the length changes, so an appropriate grip strength is applied or sustained. We must make certain efforts. In the fixed structure of the conventional gripping part structure 10 shown in FIG. 1, the suitcase is controlled by applying force in a state where the posture of the hand is not preferable, and the muscles of the hand are easily fatigued.

Therefore, as shown in FIG. 7, when the annular gripping portion 30 is operated by the continuous pressing of the control button 40 and rotated to the required tilt operation angle, and the control button 40 is released after adjustment, the control shaft 70 is released. Rotates again to the normal fixed position shown in FIG.
As shown in FIG. 8, a stereotaxic shape having an inclination angle is formed between the annular gripping portion 30 and the joining tube 20, and the gripper rotation adjusting mechanism for the suitcase pulling rod according to the present invention allows the user to hold the suitcase. The angle is adjusted to the appropriate angle for gripping by hand when pushing and pulling, and the annular gripping part is also adapted to the actual use requirements for the user to control the push-pull movement of the suitcase by hand, and requires no force Has the technical effect of avoiding that it becomes defective and dragged and scratched.

Next, in each rotation adjusting mechanism according to the present invention, a traction member 90 is further installed between the positioning base 60 and the insertion port 21 of the joining pipe 20, and the expansion / contraction position setting mechanism (the expansion / contraction position setting mechanism of the expansion / contraction bar of the suitcase) (See FIGS. 4 and 6). A control slope 70 is provided at the end of the prismatic step 73 of the control shaft 70, and the control slope 74 penetrates the polygonal hole 63 of the positioning platform 60 and is an insertion port for the positioning platform 60 and the joining pipe 20. 21. Further, the pulling member 90 is formed into a rectangular block body and is provided with a rod- like hole 91 through which the lock pin 211 of the joining tube 20 can be inserted. One end of the pulling member 90 is a pressure-control slope of the control shaft 70. 74 and a slope 92 for guiding are provided, and the other end is connected to an expansion / contraction position setting mechanism (not shown) of an expansion / contraction bar by an interlocking line 93.

When the control shaft 70 is pulled by the interlocking member 80 and moves along the axial direction, the pulling-down slope 74 of the control shaft 70 is brought into contact with the guide slope 92 of the pulling member 90, so that the pulling member 90 is positioned. It moves up and down the texture pedestal 60 and the joining tube 20, and the hole end of the rod-like hole 91 is restricted and moved with respect to the lock pin 211 of the joining tube 20.
In the case where the annular gripping portion 30 and the joining pipe 20 are in a pressing and rotating form, the pulling member 90 moves when the ratchet step 72 of the control shaft 70 moves backward from the ratchet hole 52 of the engaging member 50 and the interlocking line 93 is moved. It is pulled and the expansion / contraction position setting mechanism is loosened, and the expansion / contraction bar has a length adjusting ability.
The pulling member 90 is controlled when the ratchet step 72 of the control shaft 70 is accommodated in the engaging member 50 and the positioning base 60 ratchet holes 52 and 61 when the annular gripping portion 30 and the joining tube 20 are in a fixed configuration. The shaft 70 is brought into contact with the interlocking member 80, the pulling member 90 moves upward, pulls the interlocking line 93 to localize the telescopic position setting mechanism, and the telescopic rod is localized at a specific length.

  It should be noted that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.
