Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a transportation display case for storing merchandise such as food and daily necessities, transporting it by truck or the like and displaying it as it is.

[0002]

2. Description of the Related Art In the above-mentioned transportation display case for goods, for example, the applicant has already applied for a patent, JP-B-55-9.
There is one described in Japanese Patent No. 2405. That is, in the transportation display case for commodities described in this publication, support portions are horizontally provided in a plurality of vertical directions on both inner side surfaces of a frame whose entire plane is U-shaped. The shelves are respectively supported on the supporting portions. The shelf is configured to be folded upward in a mountain shape along a folding line formed on the left and right in the center of the front-rear direction. A caster is provided at the lower end of the frame so that it can be moved.

Then, as shown in FIG.
1 is a rear shelf 10 arranged on the rear side of the folding line 103.
5 and the front shelf 107 arranged on the front side are connected via a hinge 108. Then, the rear end locking pin 109 provided at the rear end of the rear shelf 105 is locked in the T-shaped locking groove 113 provided at the rear end of the support portion 111. The T-shaped locking groove 113 has a substantially T-shape that is entirely upside down.
The lower end of the character is opened upward to receive the rear end locking pin 109. A similar second T-shaped locking groove 115 is also formed in the support portion 111 in front of the T-shaped locking groove 113, and is provided at the tip of the front shelf 107 in a state where the shelf 101 is folded. The folded locking pin 117 is locked so that the folded state can be maintained.
Further, an L-shaped locking groove 121 is formed at the tip of the supporting portion 119, and the folding locking pin 117 provided at the tip of the front shelf 107 is locked and extended when the shelf 101 is extended. It is possible to keep the state.

[0004]

However, the hinges 108 are provided at a plurality of positions along the folding line 103 between the front end surface of the rear shelf 105 and the rear end surface of the front shelf 107. Then, a gap S is formed between the rear end surface of the front shelf 107 and the front end surface of the rear shelf 105 by the size of the shaft 108a of the hinge 108.

When the space S is formed, the stored goods do not slide smoothly when sliding on the upper surface of the shelf. That is, there is an inconvenience that the product is caught in the step formed by the gap S and, for example, a tall product falls.

In order to reduce the clearance S formed by the dimension of the shaft 108a of the hinge 108 to 0, the hinge 108 is moved below the shelf 101, and the shaft 108a moves between the rear end surface of the front shelf 107 and the rear shelf 105. It is desirable not to exist between the front end face. But in that case, hinge 10
8 protrudes below the shelf 101 and reduces the space for storing the product in the lower shelf.

The above problems have been described with respect to the case where the shelf 101 is folded upward in a chevron shape. However, even when the folding is performed in a valley shape in the opposite direction, for example, a fixed rear shelf is opposed to a front shelf. The same problem occurs when the front side of the is rotated upward to perform folding. In other words, in this case, the hinge must be moved upward in order to make the gap zero, but when it is moved upward, when the product slides on the upper surface of the shelf, the product collides with the hinge that has moved upward. Will end up. Therefore, it is very difficult to reduce the gap to zero.

The present invention has been made in order to solve the above problems, and the gap between the front shelf and the rear shelf can be made zero, and the stored goods can be smoothly slid. At the same time, it is an object of the present invention to provide a product transportation display case that can eliminate a reduction in space for storing products.

It is configured to be folded in an L shape. That is, the front side of the front shelf 15 is rotated upward with respect to the fixed rear shelf 13 to perform folding. The first and second shelves 11 from the top in FIG. 1 are already folded. The third and fourth shelves 11 are in an extended state. Casters 19 are provided at the lower end of the frame 3 so that the entire commodity display case 1 can run.

The structure of the shelf 11 will be described in detail below with reference to FIG. The side frames 23 of the front shelf 13 are welded to the left and right sides of the front frame 21. Then, the front frame 21 and the left and right side frames 2
The shelf 25 is welded onto the top of the 3. The front frame 21 has an L-shaped cross section, and the L-shaped corner portions are directed outward and downward. Side frame 23
Has an L-shaped cross section, and the corners of the L-shape are directed outward and upward.

The plate-shaped shelf plate 25 is welded to the L-shaped horizontal side 25 of the front frame 21 and the L-shaped horizontal side 27 of the side frame 23 (FIG. 5) thus arranged. This shelf board 25
A large number of holes are drilled in this to form a mesh structure. Further, a ridge 29 having a semicircular cross section is formed in the left-right direction in front of the shelf plate 25 to prevent the stored products from shifting. The rear end of the shelf plate 25 is bent into an L shape, and the rear end face 30
To form

The front frame 21 and the side frames 23 are made of a plate material having a larger wall thickness than the shelf plate 25 to improve the strength of the entire front shelf 13. The fence member 31 is gas-welded onto the front frame 21.

The rear shelf 15 has a shelf plate 3 on the left and right side frames 33.
5 are welded. The welding is performed on the horizontal side 37 of the L-shaped cross section of the side frame 33. The shelf plate 35 has substantially the same structure as the shelf plate 25 of the front shelf 13, but the convex shape 39 is provided at the rear. The front end of the shelf plate 35 is bent in an L shape to form a front end face 41, like the rear end of the shelf plate 25.

With the shelf 11 extended, the rear end surface 30 of the front shelf 13 and the front end surface 41 of the rear shelf 15 are arranged so as to abut each other. Then, near the both ends of the folding line 18, the front shelf 13
On the rear shelf 15, projecting arms 43 and 45 for constructing the special hinge 17 are projected. This protruding arm 43, 4
5 is provided so as to project upward from the upper surface of the shelf 11. Both projecting arms 43 and 45 have a substantially L shape, and
One end of the letter overlaps. The other end of the L shape is the back shelf 1 of each

A rotating shaft 47 is fixed to the protruding arm 45 of the rear shelf 15 at the overlapping portion. Further, a long hole 49 is formed in the protruding arm 43 of the front shelf 13. This long hole 49 is for inserting the rotating shaft 47,
The shelf 11 is formed long in the longitudinal direction of the shelf 11 in the extended state.

In this way, the rotary shaft 47 provided on both the protruding arms 43 and 45 is provided above and in front of the folding line 18 (upper left in FIG. 2). The rotating shaft 47 is composed of, for example, a flat rivet.

The rear shelf 15 is fixed to the frame 3 by rivets using the rivet holes 51. Hooks 53 are provided on the left and right ends of the front shelf 13 in front of the protruding arms 43. The hook 53 has an L-shape facing rearward. Then, in the state where the front shelf 13 is rotated at a substantially right angle with respect to the rear shelf 15 (FIG. 3), the frame 3 is provided with a locking portion 55 to which the hook 53 is locked. This locking is performed by pushing down the front shelf 13 by the action of the elongated hole 49.

The folding operation of the shelf will be described below. That is, the operation when the shelf 11 is folded as shown in FIG. 3 from the state where the shelf 11 is extended as shown in FIG. 2 will be described. In order to fold the shelf 11 in this manner, the front shelf 13 is pulled forward (the hook 53 in FIG. 3 is in the A state) and lifted (the hook 53 is in the A to B state), and the rotation shaft 47 is rotated. Rotate upwards. By pulling it toward you, a slight backlash of the rotary shaft 47 composed of a rivet or the like can be utilized to enable smooth rotation. In this rotation, since the rotation shaft 47 is located above the upper surface of the shelf 11, even if the rear end surface 39 of the front shelf 13 and the front end surface 41 of the rear shelf 15 are butted against each other and the clearance is zero. , Done easily.
That is, by the rotation, the rear end surface 39 of the front shelf 13 is moved to the rear shelf 1.
5 moves away from the front end face 41. Therefore, both ends 39 and 41 are smoothly rotated without rubbing against each other.

In a state in which this rotation is made to a substantially right angle (FIG. 3), the front shelf 13 is pushed down (hook 5 in the figure).
3 is from B to C). The pushing down is easily performed by the weight of the front shelf 13. By this pushing down, the hook 53
Moves down and locks on the locked portion 55 provided on the frame 3. Even if the front shelf 13 is pushed down in this way, the rotating shaft 47
Is provided in front of the folding line 18 of the shelf 11, the tip of the protruding arm 43 and the rear end surface 30 of the front shelf 13 are provided.
However, there is no interference such as hitting the rear shelf 15.

(Other Embodiments) In the above embodiments, the front shelf 13 is rotated upward with respect to the fixed rear shelf 15, that is, the shelf 11 is folded in a so-called valley shape. . However, in other embodiments, the present invention can be practiced even when the shelves are folded in a chevron shape.

That is, the shelf 1 as in the conventional example shown in FIG.
Even when 01 is folded upward along the folding line 103 in a chevron shape, the projecting arms 43 and 45 (FIG. 2 and FIG. 3) are projected toward the lower outside of the lower surface of the shelf 101 near both ends of the folding line 103, By rotating about the rotation shaft 47 provided on the projecting arms 43 and 45, the front shelf 13 and the rear shelf 15 are relatively rotated, so that the folding is performed upward in a chevron shape. May be. Even in this case, the rotation is
The projecting arms 43 and 45 are formed on the projecting side (lower side), and the front shelf 13 and the rear shelf 15 are folded in a direction facing each other on the projecting side.

In this way, the present invention can be carried out even when the shelves 11 are bent in a mountain shape, that is, in the case where FIGS. 3 and 4 are turned upside down. Folding is possible from a state in which 30 and the front end face 41 of the rear shelf 15 are butted against each other and the gap is zero. Further, the shelf 11 can be extended from the folded state so that the gap becomes zero.

[0027]

As described above, according to the first or second aspect of the invention, the front shelf and the rear shelf are relatively rotated around the rotation provided on the protruding arm. This rotation is performed on the side where the protruding arm is provided so that the front shelf and the rear shelf are folded in a direction in which they face each other. Then, since it is rotated around a rotation axis provided outside the surface of the shelf to perform folding, the rear end surface of the front shelf and the front end surface of the rear shelf are abutted and folded even if there is no gap. Can be done.

According to the second aspect of the present invention, further, since the rotating shaft is provided on the front side above the folding line, even if the front shelf is pushed down to lock the hook, the protruding arm and the rear end surface of the front shelf. Does not interfere with the back shelf. Therefore, the hooks are locked and the front shelf can be held in a state of being folded at a substantially right angle.
