Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mobile basket stand whose position can be fixed with outriggers.

[Conventional technology]

As shown in FIG. 14, the mobile basket stand includes a basket 1, a backboard 2 that supports the basket 1, a board support arm 3 that supports the backboard 2, and the board support arm 3 that can be rotated in the vertical direction. an arm lifting device 5 such as a hydraulic cylinder that is supported by the traveling truck 4 or the board support arm 3 and that raises and lowers the board supporting arm 3; Those equipped with an outrigger 6 that performs this function are widely used.

[The problem that the idea aims to solve]

However, in this type of conventional mobile basket stand, there was a problem in that the position fixing (positioning) operation using the outriggers was troublesome.

The object of the present invention is to provide a mobile basket stand equipped with outriggers that has a relatively simple structure and does not require troublesome operations.

[Means for solving problems]

The outrigger comprises a ground base, a ground base support arm with the ground base attached to the lower end, and a bearing piece rotatably attached to the upper end of the ground base support arm with a pivot, and the ground base The support arm was attached to the traveling carriage so as to be freely raised and lowered by an arm elevation guide, and the bearing piece was attached to the outer periphery of a rotating shaft rotatably attaching the board support arm to the traveling carriage.

[Effect]

When the board support arm is lowered, the rotating shaft that attaches the board supporting arm to the traveling cart rotates in one direction, and the bearing piece attached to the outer circumference of the rotating shaft also rotates in the same direction. The ground base support arm attached to the bearing piece is lowered along the arm elevation guide provided on the traveling vehicle, and the ground base attached to the lower end of the ground base support arm is grounded to the floor, etc. , fixes the position of the traveling trolley.

When the board support arm is raised, the rotating shaft rotates in the opposite direction to the direction when the board support arm is lowered, and the bearing piece raises the ground base support arm, causing the ground base to rise above the floor and move the traveling trolley. becomes driveable.

〔Example〕

Next, embodiments of the present invention will be described with reference to FIGS. 1 to 13. 1 is a basket, 2 is a backboard to which basket 1 is attached, 3 is a backboard 2
A board support arm 4 supports the board support arm 3 rotatably in the up-and-down direction (up-and-down direction); 5 is a traveling truck attached to the traveling truck 4; The arm lifting device 6 is an outrigger that fixes the position of the traveling carriage 4.

The backboard 2 has an aluminum frame 2b attached to the four peripheries of an acrylic plate 2a using fasteners 2c such as bolts and nuts.
It is formed by tightening with.

Further, the board support arm 3 has one end pivotally supported by the traveling carriage 4 by a rotating shaft 12, and is a first arm 3 that is raised and lowered by the arm lifting device 5.
a, and a foldable (first
(can be folded over the arm 3a),
A second arm 3b with the backboard 2 attached to its tip and a first arm 3 of the second arm 3b.
One end side is pivoted to the pivot side end part a, the other end side is pivoted to the traveling truck 4, and the first arm 3
and a third arm 3c which extends the second arm 3b at a substantially right angle when the first arm 3a is raised and erected. 3d is the first
A pivot shaft that pivotally supports the second arm 3b at the tip of the arm 3a, 3e is a bearing protrusion provided on the upper part of the first arm 3a, and 3f is provided on the lower surface of one end side of the second arm 3b. The recess 3g is a roller attached to one side of the recess 3f, and 3h is a V-shaped roller holder provided on one side of the first arm 3a. The second arm 3b is rotatably (foldably) supported at the tip of the first arm 3a by a pivot shaft 3d with the bearing protrusion 3e fitted into the recess 3f. When the second arm 3b is extended at a substantially right angle to the roller 3a, the roller 3g
is fitted into the roller holder 3h and the second arm 3
b and the backboard 2 attached to its tip are prevented from rolling.

Further, the traveling trolley 4 is capable of traveling by front wheels 4a and rear wheels 4b, and a hydraulic cylinder is used in the arm lifting device 5.A cylinder body 5a is attached to the traveling trolley 4 side, and a piston rod 5
By expanding and contracting b, the first arm 3a and the third arm 3c are raised and lowered.

Outrigger 6, which is the gist of this invention,
It consists of a ground base 7, a ground base support arm 8 with the ground base 7 attached to its lower end, and a bearing piece 10 rotatably attached to the upper end of the ground base support arm 8 with a pivot 9. There is.

The grounding base 7 is made of a non-slip rubber plate 7a.
It consists of a metal base body 7b with the rubber plate 7a adhered to the lower surface thereof, and arm-receiving cylindrical portions 7c erected at the left and right ends of the base body 7b.

Further, the ground base support arm 8 includes a pair of threaded rods 8b, 8b attached to the cylinder portions 7c, 7c with fasteners 8a such as screws, and these threaded rods 8a.
Shafts 8c, 8c with b, 8b screwed onto the lower end
, a shaft holder 8d supporting the upper ends of the shafts 8c, 8c, and a pair of left and right bearing pieces 8e, 8 provided on the upper surface of the shaft holder 8d.
It consists of rotating arms 8g, 8g whose lower ends are pivotally supported by pivots 8f, 8f.

By fitting the shafts 8c, 8c into slide collars serving as arm elevation guides 11, 11, the ground base support arm 8 is attached to the traveling carriage 4 so as to be movable up and down.

Further, one end of the bearing piece 10 is rotatably attached to the upper end of the rotating arms 8g, 8g with a pivot 9, and the other end rotatably attaches the board support arm 3 to the traveling truck 4. The rotary shaft 12 is fixed to the outer peripheral surface of the rotary shaft 12. and,
When the first arm 3a is raised and rotated on the traveling carriage 4 at an elevation angle of 50° or more, the bearing piece 1
0 and 10 and the rotating arms 8g and 8g are extended in a nearly straight line, the grounding base 7 is grounded on the floor F, and the front part of the traveling trolley 4 is fixed in position, and vice versa. The first arm 3 is placed on the traveling trolley 4.
When lowered at an elevation angle of 50° or less, the bearing piece 10,
10 and rotating arms 8g, 8g are approximately at right angles,
The grounding base 7 is raised from the floor surface, and the position of the traveling carriage 4 is released.

The outer rigger 6 of the embodiment has the above-mentioned configuration, and when the board support arm 3 is rotated up and down, the ground base support arm 8 automatically expands and contracts, and the position of the traveling cart 4 is automatically fixed by the ground base 7. It is done to. In Fig. 13, reference numeral 13 is a threaded rod operation handle, and by inserting the handle 13 into the handle receiving hole 8b' provided in the threaded rod 8b and turning the threaded rod 8b, it can be adjusted to the floor surface F, etc. , the degree of protrusion of the threaded rod 8b relative to the shaft 8c can be adjusted.

[Effect of idea]

The mobile basket stand of the present invention has the configuration as described above, and a bearing piece is attached to the outer periphery of the rotating shaft on which the board support arm is rotatably attached to the traveling cart, and the bearing piece is connected to the rotating shaft. Since the structure is such that the ground base support arm and the ground base can be raised and lowered by rotating them together, a pinion is attached to the conventional rotation shaft side, a rack is mounted to the ground base support arm side, and the engagement of the two allows the ground base to be raised and lowered. The structure is simpler than those that are lifted and lowered,
Moreover, there is an effect that the ground base can be raised and lowered reliably.
