[Technical field to which the invention belongs]

 The present invention relates to a baggage carrier handle in which a control unit can adjust a telescopic position of a handle.

[0002]

[Prior art]

 As social patterns change and living standards improve, people are more likely to travel and work abroad and abroad, and will the necessary goods be already integrated with the luggage for portable transportation? Alternatively there is a separate baggage carrier, which includes an adjustable telescopic drawbar. There are two types of pulling rod expansion and contraction positioning methods, one that can adjust the expansion and contraction in multiple stages and the other that can only adjust the expansion and contraction in two stages. The former uses a single handle as shown in Fig. 1. And a telescopic tube provided at the bottom of the handle, the handle has a rectangular annular shape, and has a grip portion and a hollow convex column at upper and lower central bottom ends, and one pressing portion at a front end of the grip portion. A hole is provided in the wall of the handle, and one accommodation chamber is provided in a portion corresponding to the pressing portion, and a spring is mounted therein. The telescopic tube has an inner tube inserted into an outer tube so as to be extendable and retractable, an upper end of the inner tube is fixed in a hollow convex column, and a bottom end of the inner tube is fitted on a brake seat. There are two bottom seats and a control unit thereon, and the control unit is inserted into the inner tube, and a telescopic rod controlled by an L-shaped piece is provided in the side surface thereof. A spring is provided at a distal end position of the telescopic rod in the control unit. An end of the telescopic bar opposite the spring protrudes from a hole formed in the bottom of the inner tube, one end of one drawing line is connected to the end of the L-shaped piece, and the other end of the drawing line is the handle. It is passed through a hole in the inside. When the push part of the handle is pressed, the drawing line is pulled upward, the L-shaped piece is pulled upward and swings and pushes the telescopic rod inward, which compresses the spring and saves elastic energy When the pressing portion is released, the spring in the storage chamber of the handle extends, and the L-shaped piece swings in the opposite direction to release the compression on the telescopic rod, and at the same time, releases the elastic energy stored by the spring. As a result, the telescopic rod is pushed outward and protrudes from the hole of the inner tube. Although this operation structure achieves the purpose of positioning the pull rod, it has the following disadvantages in use.

[0003] That is, the expansion and contraction of the pull bar is transmitted by a movable portion mounted in the handle. In other words, when the pressing portion is pressed or released, the drawing line is pulled up or released, and the L-shaped piece is swung to expand and contract the extension rod, thereby positioning and positioning between the inner tube and the outer tube. Release is performed. Each time the draw bar is positioned in this manner, by operating the pressing portion to push up and release a single portion of the drawing line corresponding to the pressing portion, elastic fatigue occurs in a part of the drawing line. When this occurred, the drawing line was stretched and deformed, so that even if the pressing portion was pressed, the draw bar could not be pulled up with certainty, so that it was impossible to drive the L-shaped piece and thereby control the expansion and contraction of the expandable bar. In addition, if the operation of pressing the pressing portion as much as possible is repeated to ensure the operation of the L-shaped piece with respect to the telescopic rod, the function of suppressing the drawing line is quickly lost, and the service life of the rod is shortened. Was.

Used for locking by 101. The control unit 100 is inserted into the inside of the inner tube 72, and a telescopic bar 101 that operates under the control of the L-shaped piece 102 is provided on a side wall thereof. One spring is provided at a position inside the control unit 100 at the end of the telescopic rod 101, and the other end of the telescopic rod 101 projects outside through a hole formed in the side wall at the bottom of the inner tube 72. One end of one draw line 80 is connected to the end of the L-shaped piece 102, and the other end of the draw line 80 is fixed to a projecting bar 62 at the lower part of the brake seat 60. Since the above is not a feature of the design of the present invention, further detailed description is omitted.

The features of the present invention are as follows. An elongated hole 11 into which the push switch 30 is fitted is provided in an intermediate portion of the upper lid 10. The base sheet 20 is combined with the upper lid 10, and one long hole 21 is provided at each of two ends of its inner surface, and one convex pillar 22 is provided at the center portion. One fulcrum rib 23 is provided between the columns 22, and the operation piece 50 is laid on the fulcrum rib 23. The push switch 30 has one position limiting block 31 on both sides. The operation piece 50 has a concave groove 51 at one end thereof for receiving the pressure control of the position limiting block 31 of the push switch 30, and a convex extension 52 at another end, and the concave groove 51 and the convex extension 52. One notch 53 is provided in the bottom surface between the two. The brake seat 60 has, on its side, one position limiting groove 61 into which the protruding portion 52 of the operating piece 50 is inserted, and is inserted into the inner tube 72 of the pull rod 70, and one protrusion at the bottom. A lead wire 62 of a draw bar 70 is connected to the protruding bar 62 with an extension bar 62.

With the above structure, the brake seat 60 is inserted into the elongated holes 21 formed on both sides of the base sheet 20 of the handle, and the position limiting grooves 61 in the portion of the brake seat 60 protruding into the handle from the elongated holes 21. The protruding portion 52 of the operating piece 50 is fitted and placed, and the two operating pieces 50 are straddled over the fulcrum rib 23 on the inner surface of the base sheet 20 at the notch 53 on the bottom surface thereof. A position limiting block 31 forming an opening directed downward on the side surface of the push switch 30 is placed in the concave groove 51 at the end opposite to the portion 52, and the push switch 30 is connected to the outer periphery of the convex column 22 of the base sheet 20. The push switch 30 is inserted into the long hole 11 of the upper lid 10 from below, and the upper lid 10 and the base sheet 20 are screwed. Thus, the handle structure of the present invention is completed. It is completed (see FIG. 3).

As shown in FIGS. 4 and 5, when the user grips the handle and presses the push switch 30, the push switch 30 moves downward and the position limit blocks 31 on both sides of the push switch 30 operate. The concave portion 51 of the piece 50 is pressed to cause the operating piece 50 to perform a lever motion with the fulcrum rib 23 of the base sheet 20 as a fulcrum, thereby protruding the outer end of the operating piece 50 in the position limiting groove 61 of the braking seat 60. The extension portion 52 is raised and the inner pipe 72 of the pull rod 70 connected to the lower tank body 63 of the position limiting groove 61 of the brake seat 60 is moved upward by the positioning pin 73 to move the inner pipe 72 below the brake seat 60. The pulling line 80 connected to the protruding rod 62 is pulled up to cause the telescopic rod 101 of the control unit 100 in the inner tube 72 to perform a retracting operation. When the user pushes the push switch 30 in this manner, the two operating pieces 50 perform symmetric swinging operations on both sides of the base sheet 20 with the fulcrum rib 23 as a fulcrum, and the protruding and extending portions 52 operate reliably. By driving the brake seat 60, the inner pipe 72 of the pull rod 70 can be moved and adjusted. That is, the operating piece 50 is pressed in two directions and the telescopic rod 70 is adjusted in the pull rod 70. The locking of the outer tube 71 to the hole 91 of the locking strip 90 by the telescopic bar 70 can be released. When the user opens the push switch 30, the lower spring 40 is restored to its original state by elasticity, and the two operating pieces 50 are released from the pressure control on the inner end thereof, become horizontal, and the The telescopic bar 101 of the control unit 100 projects outward again, and the position of the pull bar is determined. One bolt 24 is screwed into the protruding column 22 of the base sheet 20 from below, and the height of the bolt 24 protruding from the surface of the protruding column 22 causes the bolt 24 to move below the push switch 30 and move the operation piece 50. The movement width is limited, thereby restricting the amount of expansion and contraction of the telescopic rod 101 of the brake unit 100 that is linked to the distance moved on the brake seat 60, and occurs when the telescopic rod 101 hits the hole 91 of the locking strip 90. The sound can provide an auxiliary effect to notify the user of the achievement of the positioning after the extension and retraction of the pull bar.

Further, as shown in FIG. 2, two positioning pillars 25 are provided between the convex pillars 22 and the two fulcrum ribs 23 on the inner surface of the base sheet 20 of the present invention, respectively. The operating piece 50 is fitted between the two to prevent the operating piece 50 from swinging left and right when swinging. Further, a stop piece 32 protruding downward from the inner upper surface of the position limiting block 31 of the push switch 30 and located near the inner end of the operation piece 50 is provided, and the stop piece 32 prevents the operation piece 50 from moving back and forth. This restricts the operation piece 50 to ensure stable swinging, so that the telescopic rod 101 can be reliably driven to perform positioning with respect to the pulling rod and release of positioning.
