Abstract

PURPOSE:To make it possible to efficiently attach and exchange a wheel by means of a single bolt, by locking the top seat plate of a wheel supporting frame and a T-shaped piece mounted thereon in respective pairs of front lock pieces and back lock pieces, formed at the four corners of lower bottom surface of a base. CONSTITUTION:The top seat plate 6 of a free wheel 4 is advanced along the lower bottom surface of a base A, and the tip of the top seat plate 6 is inserted in the space between a pair of front lock pieces 2, 2 formed at the corner of the lower bottom surface of the base A, while the tip corner angle part of the top seat plate 6 is locked in a pair of back lock pieces 1, 1 formed at the lower bottom surface corners of the base A. And a T-shaped piece 7 projecting on the right and left sides at the rear end of the top seat plate 6 is locked in front lock piece 2. With this arrangement, the top seat plate 6 is restrained from shifting in the length direction and both side directions by means of the vertical L-shaped pieces 1a, 2a of respective lock pieces 1, 2 and the rolling is prevented, and thus it is possible to prevent its separation in the downward direction from the base A by means of horizontal part pieces 1b, 2b of respective lock pieces 1, 2.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wheel attachment device for a transport vehicle used in supermarkets, shops, etc.

(Prior Art) and (Problems to be Solved by the Invention) Conventionally, in this type of wheel mounting device, one wheel is
) It required four bolts, and it took a lot of effort and time to install the wheels during the manufacturing stage of the transport vehicle.

In addition, the wheels of transport vehicles are subject to high wear and tear, and with conventional equipment, it takes a lot of time and effort to replace the wheels.Especially when used in supermarkets, restaurants, or outdoors, the wheel mounting bolts may become rusty or dusty. Due to the wear resistance of conventional products, it is not easy to replace them when there are many bolts to attach them.

(Means for Solving the Problems) The present invention has been proposed in order to solve the above problems, and includes a horizontal part connected to the lower edge of each L-shaped vertical part on the bottom surface. A pair of opposing deep locking pieces, and a pair of front locking pieces that face each other at a wider interval than the locking pieces in front of the deep locking pieces are suspended from the base plate. The tip of the top seat plate of the vehicle/shaft support frame, which has a T-shaped piece that protrudes on both left and right sides and has a bolt hole in the center, is attached to the pair of front fittings along the bottom surface of the base plate. It is advanced so as to penetrate between the locking pieces, and both corner parts of the tip end are engaged with each of the inner locking pieces, and connected to the front edges of both sides of the T-shaped piece and the same front edge. After engaging the side edges with each of the front locking pieces, a bolt is inserted into a bolt hole of the T-shaped piece and screwed onto the base and tightened. It is related to the method.

(Function) As described above, in the present invention, the top seat plate of the wheel support frame, which has a T-shaped piece at the base end that protrudes on both left and right sides and has a bolt hole in the center, is placed under the platform of the carrier. Move the seat plate forward along the bottom surface, pass the tip of the seat plate between the pair of opposing front locking pieces arranged on the bottom surface of the base plate, and insert The front end corners of the seat plate are engaged with the front locking pieces, and the front edges of the protrusions on both sides of the T-shaped piece and the side edges connected to the front edges are engaged with the front locking pieces.

At this time, the tip corner of the top seat plate and the front and side edges of the protrusions on both sides of the T-shaped piece are respectively locked to the deep part and the L-shaped vertical part of the front locking piece. , the movement of the top seat plate in the depth direction, as well as the left and right directions is restrained, and lateral vibration is prevented, and the horizontal parts of both the locking pieces prevent the top seat plate from moving downward from the base plate. Desorption is prevented.

In this state, the top seat plate is securely attached to the base plate by inserting a bolt into the bolt hole of the T-shaped piece and tightening it to the base plate, and thus the top seat plate is firmly attached to the base plate. The wheel is attached to the wheel by a single bolt.

(Effects of the Invention) According to the present invention, as described above, the top seat plate of the wheel support frame has four
It can be attached to the base plate with a single bolt without having to tighten each corner with a bolt to the base plate as in the conventional method, and the work of installing and replacing the wheels of the transport vehicle can be done by tightening and loosening a single bolt. The work is done easily and quickly.

(Example) The present invention will be described below with reference to the illustrated embodiments.

Attach L-shaped vertical pieces (1α) to the four corners of the bottom of the carrier platform.
A pair of opposing deep locking pieces (1) with horizontal pieces (1h) connected to the lower edge of the L-shaped vertical piece (2α) are cut and raised horizontally to the lower edge of the L-shaped vertical piece (2α). The pieces (2h) are arranged in a row, and a pair of front locking pieces (2) are cut and raised and are arranged opposite each other at a wider interval than the inner locking piece (1).

Furthermore, a bolt hole (3) is bored in the middle of the pair of front locking pieces (2).

(4) is the free wheel of the transport vehicle, (5) is the support frame for the wheel (4), (6) is the top seat plate, and the rear end of the seat plate (6) has a T-shape that protrudes on both left and right sides. A piece (7) is provided, and a bolt hole (8) is drilled in the center of the T-shaped piece (1).

Then, attach the top seat plate (6) to the base plate (along the lower bottom surface of the Al), and the tip of the seat plate (6)
1+21 so as to pass through the seat plate (6).
When the tip corners of the T-shaped piece (7) are locked with the respective inner locking pieces (IHI), the front edges of the left and right protrusions of the T-shaped piece (7) and the side edges connected to the front edges become the front locking pieces. Lock in (2).

In this state, the seat plate (6) is restrained from moving in the depth direction and in the left-right direction by the locking pieces (L-shaped vertical pieces (1α) (2α) of IH2+), and is prevented from swinging laterally. , and each of the locking pieces (1) (21 horizontal pieces (lb
X2b) prevents the seat plate (6) from detaching downward from the base plate (A).

In this method, the bolts (
9) inserted into the nut (
By screwing and tightening the seat plate 1α, the seat plate (6) is firmly fixed to the base plate (5), and the wheels (4) are attached to the carrier via the seat plate (6).

In this way, according to the method of the above embodiment, the four corners of the top seat plate (6) of the wheel support frame (5) are not tightened with bolts to the base plate (A) respectively, as in the conventional case, but with a single bolt. (9) can be attached to the platform (A), and the wheels of the transport vehicle (4)
Installation and replacement work can be done by tightening a single bolt (9), making the work simple and quick.

Although the present invention has been described above with reference to embodiments, the present invention is, of course, not limited to such embodiments, and can be modified in various designs without departing from the spirit of the present invention. .
