Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container carrier, and more particularly, to a carrier for manually carrying a relatively heavy container, such as a high-pressure gas container filled with oxygen, nitrogen, etc., which can be folded to the rear of the frame. Container carrier having various auxiliary legs.

[0002]

[Prior Art]

 A container carrier having a structure as shown in Fig. 4 is known for carrying a high-pressure gas cylinder or the like. The container carrier 1 has a pair of traveling wheels 2 on both sides of the lower part, and a plate-shaped container mounting part 5 protruding forward is provided at the lower end of a frame 4 having a handle part 3 at the upper end. A foldable auxiliary leg 6 is provided behind the frame 4.

An upper end portion of the auxiliary leg 6 is axially supported on the upper rear portion of the frame 4, and an auxiliary wheel (caster) 7 is provided at a lower end portion thereof. An arm 8 having a central portion bent upward is provided between the lower portion of the auxiliary leg 6 and the lower portion of the frame 4.

The arm 8 serves to regulate the opening angle of the auxiliary leg 6, and both ends of the arm 8 are axially fixed to the auxiliary leg 6 and the frame 4. Further, the bending portion 9 provided at the center of the arm 8 is provided with an opening degree control member 10 for preventing the arm 8 from bending downward.

The container transporting vehicle 1 having such a configuration carries out the unloading work of the containers with the container placing part 5 being landed on the floor, but at this time, the auxiliary legs 6 are folded. .. Then, when the container transport vehicle 1 travels, if the frame 4 is tilted to the rear handle side, the auxiliary leg 6 opens and the arm 9 opens until it becomes substantially linear (180 degrees).

When the frame 4 is erected from the running state and the container placing portion 5 is landed on the floor, the weight of the auxiliary leg 6 acts on the arm 8 and the bending portion 9 is moved upward by the weight of the auxiliary leg 6. It is bent so that the auxiliary leg 6 can be folded.

[0007]

[Problems to be solved by the device]

 However, in reality, since there is "play" in the bent portion 9, the weight of the arm 8 itself causes the bent portion 9 to open 180 degrees or more, resulting in a bent state. For this reason, the weight of the auxiliary leg 6 when the frame 4 is upright acts in the direction of bending the bent portion 9 downward, and the arm 8 cannot be bent by bending upward. In this case, the opening regulating member 10 does not bend downward.

Therefore, in actual work, when the frame 4 is erected upright, an operator pushes up the bent portion 9 to bend the arm 8 upward and folds the auxiliary leg 6.

[0009] Therefore, an object of the present invention is to provide a container carrier capable of surely folding the auxiliary legs when the frame is upright.

[0010]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the container carrier of the present invention has a pair of running wheels on both sides of the lower part, a container mounting part in front of the lower end of a frame having a handle part in the upper part, and a rear part of the frame. In addition, a foldable auxiliary leg having an auxiliary wheel at the lower end and an upper end pivotally supported on the upper part of the frame, and the middle part bent upward between the lower part of the auxiliary leg and the lower part of the frame. In a container carrier equipped with a movable arm, an elastic member for urging the arm in the bending direction is provided, or an opening degree regulating member for opening the bending portion of the arm to less than 180 degrees is provided. It is characterized by

[0011]

[Work]

 By providing the elastic member for urging the bending portion of the arm in the bending direction, the bending portion can be bent by the urging force of the elastic member even when the bending portion is opened 180 degrees or more.

Further, by providing an opening degree control member that makes the opening of the bending portion of the arm less than 180 degrees, the weight of the auxiliary leg when the frame is upright is always in the direction of bending the bending portion upward. Can be operated.

Therefore, the auxiliary leg can be automatically folded when the frame is upright.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. The same elements as those of the conventional example are designated by the same reference numerals, and detailed description thereof will be omitted.

First, FIG. 1 shows a container transport vehicle 11 formed in the same manner as that shown in FIG. 4, in which the bent portion 9 is provided between the bent portion 9 of the arm 8 and the upper portion of the frame 4. A coil-shaped spring 12 for urging in the bending direction is provided.

With such a configuration, when the frame 4 is erected upright, the spring 12 pulls up and bends the bent portion 9 even if the bent portion 9 is opened 180 degrees or more, so that the auxiliary leg 6 is bent. The weight acts in a direction to bend the bending portion 9, and the arm 8 is surely bent, so that the auxiliary leg 6 is folded.

It should be noted that the conventional opening degree regulation member 10 may be provided as necessary in case the spring 12 is cut off or the like.

FIG. 2 shows an embodiment in which a spring, which is an elastic member, is used as a helical spring 13, and the helical spring 13 is attached to the bent portion 9 of the arm 8.

In the above-mentioned coil spring 13, the coil portion 13a is wound around the shaft 9a of the bent portion 9, and the action portions 13b and 13c at both ends are respectively engaged with the engaging portions 8b and 8c provided on the arm 8. It locks and biases the bent portion 9 in the bending direction.

With the above structure, as with the spring 12, the auxiliary leg 6 can be surely folded when the frame 4 is upright.

In both of the above embodiments, the elastic member is provided at the bent portion 9, but the elastic member is provided at the connecting portion with the frame 4 or the auxiliary leg 6 at both ends of the arm 8 to indirectly bend. The part 9 may be biased in the bending direction. As the elastic member, various springs other than the above, such as leaf springs and wire springs, can be used, and rubber can also be used.

FIG. 3 shows a member near the bent portion 9 of the arm 8 that restricts the opening α of the bent portion 9 from becoming 180 degrees or more, that is, the opening α of the bent portion 9 is less than 180 degrees. It shows an embodiment in which the opening control member 21 is provided. The opening regulating member 21 is provided at the upper edge of one arm 81 and contacts the lower edge of the other arm 82 so that the bent portion 9 of the arm 8 is 180 degrees or more, preferably 160 degrees or more. It prevents it from opening.

It should be noted that the maximum opening degree by the opening degree regulating member 21 may be any angle as long as the bending portion 9 can bend due to the weight of the auxiliary leg, and the opening angle and length of the auxiliary leg, the length of the arm and the mounting position can be set. Accordingly, it can be appropriately set within the range of less than 180 degrees.

[0024]

[Effect of the device]

 As described above, the container carrier of the present invention is provided with the elastic member for urging the bendable arm provided between the auxiliary leg and the frame in the bending direction, or opening the bending portion of the arm. Since an opening control member with a degree of less than 180 degrees is provided, when the container placing part 5 is landed for loading and unloading the container, the frame 4 is set upright and the auxiliary legs are automatically and securely installed. Can be folded into
