[0067] The applicant first clarifies that throughout this specification, including the embodiments described below and the claims, directional terms are based on the directions in the drawings. Furthermore, in the embodiments and drawings described below, identical component numbers represent identical or similar components or structural features.

[0068] See also Figures 1 to 8 The luggage handle 1 provided by the present invention is coupled to a luggage assembly (not shown), specifically, a lower frame 2A and an upper frame 2B of the luggage assembly. The luggage handle 1 of this embodiment includes two lower tube assemblies 10, two middle tube assemblies 30, two upper tube assemblies 50, and a handle assembly 70.

[0069] The lower tube assembly 10 is mounted on the lower frame 2A and upper frame 2B of the tank assembly. It comprises a lower tube body 11 and a lower tube sleeve 12. Lower tube body 11 has a lower engagement hole 111 and an upper engagement hole 112. Lower engagement hole 111 and upper engagement hole 112 are located at the lower and upper sides, respectively, and on opposite sides. Lower tube sleeve 12 is connected to the upper side of lower tube body 11.

[0070] The lower frame 2A is coupled to the bottom of the lower tube 11 , and the upper frame 2B is coupled to the top of the lower tube 11 .

[0071] The middle tube assembly 30 is telescopically mounted on the lower tube assembly 10 ; the middle tube assembly 30 comprises a middle tube body 31 , a middle tube sleeve 32 , a positioning bar 33 , a middle buckle sleeve 34 , a middle control plug 35 , an actuating member 36 , an upper clamping member 37 , an upper clamping spring 37S , a lower clamping member 38 , and a lower clamping spring 38S .

[0072] The middle tube body 31 is telescopically inserted into the lower tube sleeve 12 and connected to the lower tube body 11 . The middle tube body 31 has a mounting hole 311 , and the middle tube sleeve 32 is connected to the upper portion of the middle tube body 31 .

[0073] The positioning bar 33 is fixed within the middle tube 31. The positioning bar 33 comprises a mounting portion 331, an upper positioning hole 333, a plurality of intermediate positioning holes 334, and a positioning bar base 335. The mounting portion 331 is fixed to the mounting hole 311 of the middle tube 31. Adjacent intermediate positioning holes 334 are spaced a distance P apart. A first distance D1 is defined between the upper positioning hole 333 and the nearest intermediate positioning hole 334. The first distance D1 is greater than the spacing P. Preferably, the first distance D1 is at least one, two, three, four, five, six, seven, eight, or nine times the spacing P to enhance the strength of the positioning bar 33.

[0074] Furthermore, there is a second distance D2 between the bottom 335 of the positioning bar and the nearest intermediate positioning hole 334. This second distance D2 is greater than the pitch P, thereby enhancing the strength of the positioning bar 33. Preferably, the second distance D2 is at least 1, 2, 3, 4, 5, 6, 7, 8, or 9 times the pitch P, thereby enhancing the strength of the positioning bar 33. In this embodiment, the second distance D2 is greater than the first distance D1, thereby enhancing the strength of the positioning bar 33. However, the second distance D2 can be equal to or less than the first distance D1, while still providing enhanced strength for the positioning bar 33.

[0075] In addition, the total length of all the spacings P in the present invention is not limited to be greater than, equal to, or less than the first distance D1, and the total length of all the spacings P is not limited to be greater than, equal to, or less than the second distance D2, so that the configuration can be adjusted to adapt to the strength.

[0076] The middle buckle sleeve 34 is disposed on the middle tube body 31 , and the middle control plug 35 is disposed on the middle buckle sleeve 34 . The middle control plug 35 has a lower positioning hole 353 .

[0077] The middle actuator 36 is mounted on the middle control plug 35, and the upper latch 37 is mounted on the middle control plug 35. An upper latch spring 37S presses against the upper latch 37, inserting it into the upper latch hole 112. The middle actuator 36 then controls the upper latch 37 to disengage from the upper latch hole 112. The middle actuator 36 has an inclined surface that cooperates with an inclined surface of the upper latch 37. A hook 361 is located below the middle actuator 36 to engage the middle control plug 35.

[0078] The lower clamping member 38 is disposed on the upper clamping member 37 and is abutted by a lower clamping spring 38S, so that the lower clamping member 38 can be inserted into the lower clamping hole 111 of the lower tube 11 .

[0079] The upper tube assembly 50 is telescopically mounted on the middle tube assembly 30. The upper tube assembly 50 comprises an upper tube body 51, an upper buckle 52, an upper control plug 53, an upper actuator 54, a positioning member 55, and a spring 55S. The upper tube body 51 is telescopically inserted into the middle tube body 31. The upper buckle 52 is mounted on the upper tube body 51, the upper control plug 53 is mounted on the upper buckle 52, the upper actuator 54 is mounted on the upper control plug 53, and the positioning member 55 is mounted on the upper control plug 53. The spring 55S presses the positioning member 55 into the middle positioning hole 334, the upper positioning hole 333, and the lower positioning hole 353. The upper actuator 54 controls the positioning member 55 to disengage from the middle positioning hole 334, the upper positioning hole 333, and the lower positioning hole 353.

[0080] The upper actuating member 54 is actuated by the inclined surface of the positioning member 55 linked to the inclined surface.

[0081] The handle assembly 70 is connected to the top of the upper tube assembly 50. It comprises a handle 71, an operating member 72, a spring (not shown), and two linkage members 73. The handle 71 is connected to the upper tube 51, the operating member 72 is located within the handle 71, and the spring is located between the handle 71 and the operating member 72. The linkage member 73 connects to the operating member 72, thereby driving the middle actuator 36.

[0082] The above are the structural features of the luggage pull rod 1 of the present invention. The following will further introduce the usage and function of the luggage pull rod 1 of the present invention.

[0083] To extend the handle from the collapsed state, first press the operating member 72 of the grip assembly 70. The operating member 72 actuates the linkage member 73 downward, which pushes down the upper actuating member 54. The upper actuating member 54 moves the positioning member 55 along an inclined surface, and the positioning member 55 disengages from the middle positioning hole 334 of the positioning bar 33. At this time, pulling the handle 71 of the grip assembly 70 upward can pull the upper tube assembly 50 upward to move relative to the middle tube assembly 30.

[0084] When the operating member 72 is no longer pressed, the positioning member 55 can be positioned in each middle positioning hole 334 or the upper positioning hole 333. When the positioning member 55 is positioned in the middle positioning hole 334 or the upper positioning hole 333 and no longer presses the handle assembly 70, the upper tube assembly 50 can pull the middle tube assembly 30 to move upward or downward together.

[0085] When the middle tube assembly 30 moves upward to the top dead center, that is, the upper clamping member 37 is inserted and positioned in the upper clamping hole 112 by the elastic force, the middle tube assembly 30 is positioned on the lower tube assembly 10 .

[0086] Retraction operation, such as Figure 7 and Figure 8 As shown, the operating member 72 must be pressed first, and the operating member 72 moves the connecting member 73 downward. The connecting member 73 moves downward, the upper actuator 54, and the positioning member 55 are disengaged from the middle positioning hole 334 and the upper positioning hole 333. The handle assembly 70 is pressed downward to move the upper tube assembly 50 downward relative to the middle tube assembly 30.

[0087] As the upper tube assembly 50 moves downward, its upper control plug 53 strikes the middle actuator 36, overcoming the elastic force of the upper retaining spring 37S. The inclined surface of the middle actuator 36 drives the upper retaining member 37 out of the upper retaining hole 112, allowing the middle tube assembly 30 to descend relative to the lower tube assembly 10. When fully retracted, the lower retaining member 38 inserts into the lower retaining hole 111 of the lower tube assembly 10, and the positioning member 55 is elastically inserted into the lower positioning hole 353.

[0088] That is, the upper control plug 53 presses against the middle actuator 36 and descends. The middle actuator 36 descends, and its inclined surface drives the inclined surface to cause the upper clamping member 37 to move horizontally. The upper clamping member 37 pushes the lower clamping member 38 to move horizontally, and the lower clamping member 38 is inserted into the lower clamping hole 111 of the lower tube assembly 10. Conversely, when the middle tube assembly 30 moves upward, the lower clamping member 38 is disengaged from the lower clamping hole 111, and the lower tube body 11 and the middle tube body 31 can now move relative to each other.

[0089] By making the first distance D1 greater than the pitch P, the positioning bar 33 can be made stronger. By making the second distance D2 greater than the pitch P, the positioning bar 33 can also be made stronger. By making the second distance D2 greater than, equal to, or less than the first distance D1, the positioning bar 33 can also be made stronger. Furthermore, by providing the lower positioning hole 353 in the middle control plug 35, the stability between the middle tube assembly 30 and the upper tube assembly 50 can be effectively improved.

[0090] In summary, the luggage pull rod 1 of the present invention reduces the deformation and damage of the positioning strip by changing the configuration of the positioning holes, thereby effectively achieving the purpose of the present invention.

[0091] Finally, it must be reiterated that the methods and components disclosed in the aforementioned embodiments of the present invention are merely illustrative and are not intended to limit the patent scope of the present invention. Any simple structural modifications or changes that do not depart from the spirit of the present invention, or replacement with other equivalent components, shall still fall within the scope of the patent scope of the present invention.

[0092] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims of the present invention.
