Achieve operational safety. Also, in the suitcase pull rod structure according to the present invention, the operation of storing the pull rod is completed by a single operation of pushing to the bottom.

[0005]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the pull rod of the suitcase according to one embodiment of the present invention includes a top surface 11, a pull rod 21, and a protective block 31. The top surface 11 is provided at the top of the suit case 41, and the storage groove 12 having an open structure is formed. One side of the bottom surface 13 of the storage groove 12 is provided with a stepped portion 14 having a protrusion. Between the stepped portion and the protection wall 15 of the storage groove 12, two protrusions of the fitting block 16 are provided. An interval 17 is provided between each fitting block 16 and the protection wall 15. In addition, two holes 18 are provided on the bottom surface 13 of the storage groove 12.

The pull rod 21 is composed of two telescopic pull rods 22 and a grip 23 connecting between them. Two extendable pull rods 22 provided on the pull rod 21 correspond to the holes 18 provided in the storage groove 12. Thus, the pull rod 21 can be coupled to the top surface 11 and can be extended and contracted with respect to the top surface 11.

The protective block 31 is an elongated soft packing block or a plastic block, and has two slots 32 on its surface. The bottom surface of the protection block 31 has elastic parts such as two springs 33. Note that since the slot 32 is L-shaped, a protective edge 34 is formed outside the slot 32. The protective block 31 is set on the top surface 11, and the fitting block 16 is inserted into the slot 32. The protective edge 34 is provided at a space 17 between the fitting block 16 and the protective wall 15, and the top surface of the step portion 14 is pressed by the spring 33. As a result, the protective block 31 can move up and down with respect to the bottom surface 13 of the top surface 11 and does not come off in the side direction.

As shown in FIG. 2, when the pull rod 21 of the suitcase according to the first embodiment of the present invention is pushed toward the storage groove 12 of the top surface 11, the finger 42 of the hand is moved to the protective block 31. As a result, the protection block 31 receives a downward acting force. As shown in FIG. 3, the pull rod of the suitcase according to the first embodiment of the present invention has a spring 33 provided on the bottom surface of the protective block 31, so that the finger 42 of the hand faces downward on the protective block 31. By exerting an acting force, the protective block 31 is moved to the side of the step portion 14 to compress the spring 33. Thus, the pull rod 21 is smoothly stored in the storage groove 12 of the top surface 11. More importantly, even when the finger 42 is caught between the grip 23 and the protective block 31 while the pull rod 21 moves downward, the protective block 31 is a soft packing block and has an elastic modulus. Because of the joint action with the relatively small spring 33, the finger 42 of the hand is not strongly pinched. In addition, since the protective block 31 is a soft packing block and the elastic coefficient of the spring 33 is relatively small, the finger of the operator's hand can be easily pulled out after pressing the pull rod 21 into a fixed position.

In other words, with the structure of the present embodiment, the operator can push down the pulling rod to the home position once, and it is not necessary to perform the pulling rod pressing operation twice. After the user removes the finger 42 of the hand, the protective block 31 can return to the starting position by using the restoring force of the spring 33. Conversely, when pulling out the pull rod 21, the finger 42 of the operator's hand can be easily inserted between the grip 23 and the protective block 31, and the grip 23 can be gripped.

In the present embodiment, the finger 42 of the operator does not cause the finger 42 of the operator's hand to be pinched by the grip 23 and the protective block 31 or the grip 23 and the top surface 11, thereby achieving relatively high safety. It can be said that it is easy to set up and operate, and has remarkable practicality and inventive step.

FIG. 4 shows an application of the first embodiment of the present invention. The elastic component located between the lower part of the protection block 31 and the stairs 14 in the figure is a single curved leaf spring 35 made of plastic. The leaf spring 35 is compressed and deformed when the protection block 31 receives pressure, so that the protection block 31 can move downward.

FIG. 5 is a structural explanatory view of a second embodiment of the present invention. A protection block 36 is provided between the pull rod 21 and the top surface 11 in the figure. The protective block 36 is a soft packing block, has compressibility (like sponge), and has only the bottom fixed to the top surface 11 (can be fixed to the top surface of the staircase). As a result, when the pull rod 21 moves toward the top surface 11, the protective block 36 is simultaneously compressed, and the operator does not receive the finger (not shown) and is not injured. It can be easily pulled out and meets the requirement for simplicity of operation.

FIG. 6 shows a third embodiment of the present invention. The design of the protection block 37 can be a sleeve structure. That is, a storage space 371 having an opening at one end is provided inside the protection block 37, and a spring 372 is provided in the storage space 371. One end of the guide rod 38 is fixed to the storage groove 12 of the top surface 11, and the other end of the guide rod 38 is inserted into the storage space 371 of the protective block 37 and is brought into contact with the spring 372. Thus, when the user's hand grips the grip 23 and makes the pull rod 21 face the bottom of the top surface 11 and comes into contact with the presser protection block 37, the protection block 37 moves downward under the force. At this time, the user's hand is not injured. After the pull rod 21 is moved to a predetermined position, the user can easily pull out his hand. The protection block 37 returns to the starting position and maintains the integrity of the surface appearance of the top surface 11.

FIG. 7 shows a fourth embodiment of the present invention. An elastic column 391 connects the lower part of the protection block 39 and the bottom surface 13 of the storage groove 12 shown in the figure. Since the elastic column 391 has a swinging property, when the user pushes the pull rod 21 toward the top surface 11 and the hand and the protective block 39 come into contact with each other, the protective block 39 receives the force of the side surface and the elastic block The pillar 391 is tilted to one side to provide a space through which the finger of the hand can pass, so that the finger of the hand is not pinched and hurt. After removing the finger, the protection block 39 returns to the starting position. As an application of the fourth embodiment, a protection block (not shown) that can be moved to the left and right is fitted in the protection wall 15.

As shown in FIG. 8, in the structure of the above-mentioned sleeve type protection block 37, in order to prevent a situation where the protection block 37 jumps off when returning to the starting position after receiving pressure, the protection block 37 is used. A long groove 373 is provided on the back surface of 37. Since the position limiting pin 374 is fixed on the protective wall 15 and one end of the pin extends to the inside of the long groove 373, when the protective block 37 returns to the starting position, there is no danger that it will be stopped by the position limiting pin 374 and fall off. .

The embodiments and design schemes of the present invention described above are only described as examples of relatively good embodiments and schemes, and do not limit the scope of the technology of the present invention. In the case of implementing all equivalent technical means or those which are covered by the scope of the above-mentioned “claims for registering utility model”, the scope of the present invention does not escape, but the scope of the applicant's right.
