Description

[Technical field]

[0001] The present invention relates to luggage, and more particularly to a carry bar for luggage. [Background technology]

[0002] Known luggage carrier bars are expanded and contracted by a belt-shaped positioning member. The belt-shaped positioning member has multiple evenly-spaced positioning holes. The more the positioning holes, the greater the impact on the overall strength. If multiple positioning holes are evenly-spaced, and the luggage carrier bar is positioned at the positioning holes close to both ends of the belt-shaped positioning member, the belt-shaped positioning member is subject to a relatively large stress range, making it easy to deform and break. Summary of the Invention [Problem to be solved by the invention]

[0003] In view of the above-mentioned drawbacks, the main objective of the present invention is to provide a carry bar for travel luggage that reduces deformation and damage to the belt-shaped positioning member when it withstands force by adjusting the positioning position of the positioning holes of the belt-shaped positioning member. [Means for solving the problem]

[0004] In order to solve the above-mentioned problems, the carry bar for a travel suitcase includes a lower pipe, a middle pipe, an upper pipe, and a handle member. The middle pipe is telescopically mounted in the lower pipe, and has a middle rod, a belt-shaped positioning member, and a lower positioning hole. The belt-shaped positioning member is fixed to the middle rod, and has one upper positioning hole, a plurality of middle positioning holes, and a space formed between two adjacent middle positioning holes. A distance between the one middle positioning hole closest to the upper positioning hole and the upper positioning hole is a first distance. The first distance is larger than the space. The upper pipe is telescopically mounted in the middle pipe, and has an upper stopper, an upper operating unit, and a positioning member. The upper operating unit is mounted on the upper stopper. The positioning member is actuated by the upper operating unit, and is fitted into the upper positioning hole, the middle positioning hole, or the lower positioning hole of the middle pipe under elastic force. The handle member has a handle, an operating unit, and an interlocking unit. The handle is connected to the tip of the upper pipe. The operating unit is arranged to abut against the handle under elastic force. The interlocking unit interlocks with the operation unit, and the interlocking unit interlocks with the upper stage operating unit to cause the positioning member to be released from the upper positioning hole, the middle positioning hole, or the lower positioning hole.

[0005] To sum up, the technical feature of the present invention is that by adjusting the positions of the upper and middle positioning holes of the belt-shaped positioning member, the deformation and damage of the belt-shaped positioning member when it bears force can be reduced.

[0006] In more preferred cases, the first distance is at least 1, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, or at least 9 times the spacing.

[0007] In a more preferred embodiment, the band-shaped positioning member has a bottom, and a distance between the bottom and one of the intermediate positioning holes closest to the bottom is a second distance, and the second distance is at least 1, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, or at least 9 times the interval.

[0008] In more preferred cases, the second distance is equal to, greater than, or less than the first distance.

[0009] In a more preferred case, the sum of all the intervals is equal to, greater than or less than the first distance, and the sum of all the intervals is equal to, greater than or less than the second distance.

[0010] In a more preferred embodiment, the middle pipe has a middle rod and a middle stopper. The middle stopper is fixed to the middle rod. The lower positioning hole is disposed in the middle stopper.

[0011] In a relatively preferred embodiment, the belt-shaped positioning member has a bottom portion that abuts against the middle stopper.

[0012] In a relatively preferred case, the lower pipe has an upper locking hole. The middle pipe has a middle operation unit and an upper locking member. The upper locking member is fitted into the upper locking hole of the lower pipe under elastic force. The middle operation unit releases the upper locking member from the upper locking hole by operating the upper stopper.

[0013] In a relatively preferred embodiment, the middle pipe has a middle stopper, the middle operation unit and the upper locking member are disposed on the middle stopper, and the middle operation unit has a locking hook on the middle stopper at its lower portion.

[0017] The present invention will now be described with reference to the accompanying drawings, in which: FIG. 1 is a perspective view of a luggage carrier according to a first embodiment of the present invention; FIG. 2 is a perspective view of a luggage carrier according to a first embodiment of the present invention;

[0018] (One embodiment) 1 to 8, a carry bar 1 for travel luggage according to an embodiment of the present invention is coupled to a lower support member 2A and an upper support member 2B of a body of the travel luggage (not shown in the figures). The carry bar 1 for travel luggage includes two lower pipes 10, two middle pipes 30, two upper pipes 50 and a handle member 70.

[0019] The lower pipe 10 is attached to a lower support member 2A and an upper support member 2B of the case of the suitcase (not shown in the figure), and has a lower rod 11 and a lower rod sleeve 12. The lower rod 11 has a lower locking hole 111 and an upper locking hole 112. The lower locking hole 111 and the upper locking hole 112 are located at opposing lower and upper portions of the lower rod 11. The lower rod sleeve 12 is connected to the upper part of the lower rod 11.

[0020] The lower support member 2A is connected to the bottom of the lower rod 11. The upper support member 2B is connected to the tip of the lower rod 11.

[0021] The middle pipe 30 is telescopically mounted within the lower pipe 10. The middle pipe 30 has a middle rod 31, a middle rod sleeve 32, a belt-shaped positioning member 33, a middle fitting sleeve 34, a middle stopper 35, a middle operation unit 36, an upper locking member 37, an upper locking spring 37S, a lower locking member 38 and a lower locking spring 38S.

[0022] The middle rod 31 is inserted from the lower rod sleeve 12 to the lower rod 11 in a telescopic manner, and has an attachment hole 311. The middle rod sleeve 32 is connected to the upper part of the middle rod 31.

[0023] The belt-shaped positioning member 33 is fixed in the middle rod 31 and has a protruding mounting portion 331, an upper positioning hole 333, a plurality of intermediate positioning holes 334, and a bottom portion 335. The protruding mounting portion 331 fits into the mounting hole 311 of the middle rod 31. The interval between two adjacent intermediate positioning holes 334 is P. The distance between one intermediate positioning hole 334 closest to the upper positioning hole 333 and the upper positioning hole 333 is a first distance D1. The first distance D1 is greater than the interval P. In particular, if the first distance D1 is 1 or more times, 2 or more times, 3 or more times, 4 or more times, 5 or more times, 6 or more times, 7 or more times, 8 or more times, or 9 or more times the interval P, the strength of the belt-shaped positioning member 33 can be improved.

[0024] The distance between the bottom 335 and one of the intermediate positioning holes 334 closest to the bottom 335 of the strip-shaped positioning member 33 is a second distance D2. The second distance D2 is greater than the interval P. In particular, if the second distance D2 is 1 or more, 2 or more, 3 or more, 4 or more, 5 or more, 6 or more, 7 or more, 8 or more, or 9 or more times the interval P, the strength of the strip-shaped positioning member 33 can be improved. Also, even if the second distance D2 is equal to or smaller than the first distance D1, the strip-shaped positioning member 33 can maintain good strength.

[0025] In this embodiment, the sum of all the intervals P is equal to the first distance D1, or is greater than or less than the first distance D1. The sum of all the intervals P is equal to the second distance D2, or is greater than or less than the second distance D2. In other words, the placement position of the intervals P can be adjusted according to the strength.

[0026] The middle fitting sleeve 34 is disposed on the middle rod 31. The middle stopper 35 is fitted into the middle fitting sleeve 34 and has a lower positioning hole 353.

[0027] The middle stage operation unit 36 ​​is inserted into the middle stage stopper 35. The upper locking member 37 is attached to the middle stage stopper 35 and is pushed by the upper locking spring 37S, fitting into the upper locking hole 112. The middle stage operation unit 36 ​​releases the upper locking member 37 from the upper locking hole 112. The middle stage operation unit 36 ​​has a sloping surface that corresponds to the sloping surface of the upper locking member 37, and a locking hook 361 that hooks onto the middle stage stopper 35.

[0028] The lower locking member 38 is attached to the upper locking member 37 and is pushed by a lower locking spring 38S so as to fit into the lower locking hole 111 of the lower rod 11.

[0029] The upper pipe 50 is telescopically mounted in the middle pipe 30. The upper pipe 50 has an upper rod 51, an upper fitting sleeve 52, an upper stopper 53, an upper operating unit 54, a positioning member 55 and a spring 55S. The upper rod 51 is telescopically inserted into the middle rod 31. The upper fitting sleeve 52 is disposed on the upper rod 51. The upper stopper 53 fits into the upper fitting sleeve 52. The upper operating unit 54 is inserted into the upper stopper 53. The positioning member 55 is mounted on the upper stopper 53 and is pushed by the spring 55S to fit into the intermediate positioning hole 334, the upper positioning hole 333 or the lower positioning hole 353. The upper operating unit 54 detaches the positioning member 55 from the intermediate positioning hole 334, the upper positioning hole 333 or the lower positioning hole 353.

[0030] The upper stage operating unit 54 operates the positioning member 55 by the inclined surface coming into contact with the inclined surface of the positioning member 55 .

[0031] The handle member 70 is connected to the tip of the upper pipe 50, and has a handle 71, an operation unit 72, a spring (not shown in the figure), and two interlocking units 73. The handle 71 is connected to the upper rod 51. The operation unit 72 is disposed on the handle 71. The spring is disposed between the handle 71 and the operation unit 72. Each interlocking unit 73 is connected to the operation unit 72 and operates the middle operating unit 36.

[0032] The above is a description of the structure of the carry bar 1 for travel luggage according to one embodiment of the present invention. Next, the method of use and the effects of the same will be elucidated.

[0033] When extending the carry bar 1 for travel luggage in a closed state, by pressing the operation unit 72 of the handle member 70, the operation unit 72 activates the lower interlocking unit 73, thereby pressing the upper operating unit 54 below the interlocking unit 73. Next, the upper operating unit 54 moves the positioning member 55 by the slope and releases the positioning member 55 from one of the middle positioning holes 334 of the belt-shaped positioning member 33. Next, by pulling the handle 71 of the handle member 70 upward, the upper pipe 50 rises relative to the middle pipe 30.

[0034] When the operation unit 72 is released, the positioning member 55 fits into one of the intermediate positioning holes 334 or the upper positioning hole 333. When the positioning member 55 fits into one of the intermediate positioning holes 334 or the upper positioning hole 333, the upper pipe 50 can be raised or lowered together with the middle pipe 30 as long as the handle member 70 is not pressed.

[0035] When the middle pipe 30 rises to its maximum position, the upper locking member 37 is subjected to a resilient force and fits into the upper locking hole 112. The middle pipe 30 is stabilized on the lower pipe 10.

[0036] 7 and 8, when the carry bar for travel luggage 1 is retracted and returned, by pushing the operation unit 72 to lower it, the interlocking unit 73 lowers together with the operation unit 72, and the upper operating unit 54 causes the positioning member 55 to detach from the intermediate positioning hole 334 or the upper positioning hole 333. Next, by pushing the handle member 70 downward, the upper pipe 50 lowers relative to the middle pipe 30.

[0037] When the upper pipe 50 descends and the upper stopper 53 abuts against the middle stage operating unit 36 ​​to release the elastic force of the upward locking spring 37S, the middle stage operating unit 36 ​​uses the slope to disengage the upper locking member 37 from the upper locking hole 112, allowing the middle pipe 30 to descend relative to the lower pipe 10. When the middle pipe 30 descends to its limit, the lower locking member 38 fits into the lower locking hole 111 of the lower pipe 10. The positioning member 55 fits into the lower positioning hole 353 after receiving the elastic force.

[0038] That is, the upper stopper 53 lowers the middle operation unit 36. As the middle operation unit 36 ​​lowers, its inclined surface abuts against the inclined surface of the upper locking member 37, moving the upper locking member 37 horizontally. Next, the upper locking member 37 moves the lower locking member 38 horizontally and engages it with the lower locking hole 111 of the lower pipe 10. Conversely, if the middle pipe 30 is raised, the lower locking member 38 will be released from the lower locking hole 111, allowing the lower rod 11 and the middle rod 31 to extend and retract relative to each other.

[0039] In detail, the first distance D1 is greater than the interval P, so that the strength of the belt-shaped positioning member 33 can be improved. The second distance D2 is also greater than the interval P, so that the strength of the belt-shaped positioning member 33 can be improved. The second distance D2 is equal to the first distance D1 or greater than or smaller than the first distance D1, so that the strength of the belt-shaped positioning member 33 can be improved. The lower positioning hole 353 is disposed in the middle-stage stopper 35, so that the stability between the middle-stage pipe 30 and the upper-stage pipe 50 can be effectively improved.

[0040] To sum up, the carry bar 1 for travel luggage according to the present invention can reduce deformation and damage of the belt-shaped positioning member that withstands force by adjusting the arrangement position of the positioning holes.

[0041] As described above, the present invention is not limited to the above-described embodiment, and can be embodied in various forms without departing from the spirit of the invention. [Explanation of symbols]
