When transporting luggage, place the luggage on the luggage rack 1, secure it with the band 22, and then
Holding the handle 21, tilt the hand lever 3 forward to bring the wheels 2 into contact with the ground, and in this state, pull the luggage carrier forward or push it backward.

When shortening the hand lever 3 of this luggage carrier by contracting it, first grasp the upper handle 13 and the lower handle 15 with one hand, and then move the lower handle 15 upward against the biasing force of the spring 14. Fig. 8 b arrow direction)
move it to Then, as the lower handle 15 rises, the guide pin 19 of the joint 16 is pushed by the lower side of the inner surface of the guide elongated hole 15c and moves inward.
Along with this, the engaging convex portion 17a also moves inward, and the engaging concave portion 18 between the engaging convex portion 17a and the pawl 18
b is disengaged. Then, when the handle 21 is pushed downward in this state, the lower rod 7 is inserted into the lower rod 5 with its claw 18 being guided by the protrusion 5a of the lower rod 5 (see Fig. 8c). Furthermore, when the upper end of the lower lever 7 is inserted close to the upper end of the lower lever 5, the engagement pin 29 provided on the upper lever 8 comes into contact with the inclined guide surface 13f of the upper handle, so that the engagement pin 29 comes into contact with the inclined guide surface 13f of the upper handle. The dowel pin 29 is pushed into the lower rod 8, the upper rod 8 and the lower rod 7 are disengaged and become telescopic, and the upper rod 8 is inserted into the lower rod 7 which has been inserted into the lower rod 5. As a result, it is contracted to the state shown by the two-dot chain line in FIG. Further, when the baggage holder 1 is rotated counterclockwise in the figure, the baggage carrier becomes very compact as shown by the two-dot chain line in the figure.

In addition, in contrast to the above, when this luggage carrier is to be used normally, the luggage holder 1 is rotated clockwise in Figure 2, so that the luggage holder 1 and the hand lever 3 are in a perpendicular state. Afterwards, it is best to hold the handle 21 in your hand and pull it upward. Then, the upper rod 8 is pulled out from the lower rod 7, and the engagement pin 29 of the upper rod 8 and the through hole 7 of the lower rod 7 are connected.
e is engaged, and both rods 7 and 8 are held in an extended state. Further, the lower rod 7 is pulled out from the lower rod 5,
The inclined pressing part 18c of the claw 18 of the lower rod 7 comes into contact with the tip of the engagement protrusion 17a, and moves upward while moving the engagement protrusion 17a inward together with the joint 16, causing the claw 18 to slide vertically. The upper part of the moving surface 18d is the engaging protrusion 1
7a, and the engagement protrusion 17a and the claw 18
When the engagement concave portion 18b of the engagement convex portion 1 coincides with the engagement convex portion 1
7a is urged outward by the spring 14 via the lower handle 15, so it moves outward and engages with the engagement recess 18b, and the lower rod 7 is pressed against the upper end of the lower rod 5. The hand levers 3 are fixed to the first to third positions.
The device enters the normal usage state shown by the solid line in the figure.

In this way, in the luggage carrier of this embodiment, when retracting the hand lever 3, it is sufficient to grasp the upper handle 13 and the lower handle 15 with one hand and push the handle 21. Engagement recess 1
8b and the engagement between the engaging pin 29 and the through hole 7e are released, the hand lever 3 contracts, and when the hand push rod 3 is to be extended, it is only necessary to pull up the handle 21. The engagement protrusion 17a and the engagement recess 18b and the engagement pin 29 and the through hole 7e engage, and the hand lever 3 is held in its extended state. can be expanded and contracted.

In addition to being able to extend and retract the hand lever 3, the luggage holder 1 is configured to be rotatable, so when transporting luggage, this luggage carrier can be used with the hand lever 3 in an extended state. In addition, when the vehicle is not used to transport cargo, the hand lever 3 is retracted and the cargo holder 1 is rotated to make the cargo carrier into a very compact shape, which requires less storage space. , and the transportation cost is also low.

In the above embodiment, the upper rod 6 is configured to be extendable and retractable with the upper rod 8 and the lower rod 7, but the upper rod 6 may be constructed of a single rod. The lower rod 5 has a rectangular cross section with a protrusion 5a that guides the claw 18.
However, the lower rod 5 may have a circular cross section with a protrusion similar to the above. In this case, the upper rod 6 also has a circular cross section. It is desirable to configure it in a shape.

Further, in the above embodiment, the engagement member 17 is connected to the joint 16.
This engaging member 1 is fixed with a rivet 17b.
7 may be rotatably attached to the joint 16, and in this case as well, the engaging protrusion 17a is inserted into the joint penetration hole 13g, so the engaging member 17 does not rotate and the same operation as above is performed. can perform actions. Further, in the above embodiment, the engaging member 17, the rivet 17b, and the joint 16 are constructed from separate parts, but they may be formed integrally.

As described above, according to the luggage carrier according to the present invention, the upper handle is fixed between the upper ends of the lower rod;
The upper handle is provided with a lower handle that is movable in the vertical direction and is biased downward, and the lower handle is provided with a guide elongated hole that slopes inwardly and downwardly. a slidable guide pin on the handle, a joint movable left and right on the handle, and an engagement recess capable of engaging with the engagement protrusion, and an engagement recess that is inclined inwardly and downwardly. The above-mentioned upper lever has an inclined pressing part that can come into contact with the engaging protrusion, and a claw is fixed to the lower end of the upper rod.
