Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a pallet with swinging shelves, and is mainly used when transporting a large number of instruments.

[Conventional technology]

Conventionally, this type of pallet with shelves includes a frame having a support member with long holes, and a required number of frames that are swingably pivoted to the frame so that the support members are on the sides. It includes a shelf board, a guide plate having a long hole installed on the side surface of the shelf board, and a tension rod having a pivot axis A and a pivot axis B at both ends, respectively, and the pivot axis A of the tension rod is connected to the support member. The tension rod is fitted into the elongated hole so as to be swingable and movable, and the pivot shaft B of the tension rod is fitted into the elongated hole of the guide plate so as to be swingable and movable. death,
A tension spring was installed between this protrusion and the frame to control the swinging of the shelf (Japanese Utility Model Publication No. 49-27971).

However, with this conventional pallet with shelves,
Since the tension springs protruded from the sides of the shelves, when multiple shelves were installed on the frame at short intervals, the lower shelves would easily come into contact with these springs when swinging, and as a result, the shelves would This has disadvantages in that the smooth swinging of the shelf board is hindered, and the shelf board comes into contact with the spring, which tends to generate noise.

[Purpose of invention]

This invention was made based on such circumstances, and its purpose is to provide a pallet with shelves in which a plurality of shelf boards can always swing smoothly and no noise is generated during such swinging.

[Structure of the idea]

The purpose is to provide a frame having a support member with a slotted hole, a required number of shelf boards pivotably supported to the frame so that the support member is on the side, and A guide plate having a long hole installed on the side surface of the shelf board, and a tension rod having a pivot axis A and a pivot shaft B at both ends, respectively, and the pivot axis A of the tension rod swings into the long hole of the support member. The tension rod is movably fitted into the guide plate, and the pivot shaft B of the tension rod is swingably and movably fitted into the elongated hole of the guide plate.
The swinging of the tension rods is performed when the appropriate elastic means is fitted into the pivot shaft A of the tension rods and one end of the pallet with shelves is elastically repelled in the direction of opening the shelf boards by an appropriate elastic means. This was achieved by constructing the support member and a wire spring whose other end is fixed to the tension rod.

[Explanation of Examples]

Hereinafter, embodiments of this invention will be described based on the drawings.

In FIG. 1, reference numeral 11 denotes a frame, which has pillars 13, 13, . . . and horizontal rods 15, 15, . Reference numeral 17 denotes a support member, which is spanned between the upper and lower horizontal rods 15, 15 in the vicinity of the column 13. This support member 17 supports a tension rod 37 which will be described later. 19, 19, ... are shelf boards,
It is pivotally supported on the support column 13 via shafts 21, 21, . . . Objects to be transported such as instruments are placed on the shelf boards 19, 19, . . . . 23 is a cover plate, which is located above the shelf boards 19, 19,...
9, 19, . . . are similarly pivotally supported by the support column 13. This cover plate 23 covers the shelf plates 19, 19, . . . Further, 25 is an end plate, which is stretched between the support column 13 and the support member 17. This wife board 25
protects the mechanical parts of this pallet with shelves.

Note that 27 and 29 are casters, of which 27 is fixed, while 29 is movable.

Next, with reference to FIGS. 2 and 3, the mechanism of this pallet with shelves will be explained in detail.

A guide plate 31 is fixed to the side surface of the shelf board 19. This guide plate 31 is interposed when the shelf board 19 is pivotally supported on the frame 11. Reference numeral 33 is a long hole, which is bored in the guide plate 31 in the longitudinal direction. This elongated hole 33 has a tension rod 3 to be described later.
7 axis B is inserted. Reference numeral 35 denotes a long hole drilled horizontally in the support member 17. A pivot shaft A of a tension rod 37, which will be described later, is inserted into this elongated hole 35. Next, 37 is a tension rod, with pivot A at one end,
It has a pivot B at the other end. This tension rod 37 is the shelf board 1
It supports the shelf board 19 in order to maintain the open state of the shelf board 9. In the tension rod 37, the pivot shaft A passes through a coiled wire spring 39 and is fitted into the elongated hole 35 of the support member 17 so as to be swingable.
One end of this wire spring 39 is fixed to the support member 17, and the other end is fixed to the tension rod 37.
7 in the counterclockwise direction (Figures 1 and 2). On the other hand, the pivot B consists of a center pin, and is fitted into the elongated hole 33 of the guide plate 31 so as to be swingable. 41
is a collar, which is inserted into the shaft B. This collar 41 allows the pivot shaft B to be easily moved within the elongated hole 33. In addition, 43 is a washer, 45
is a split pin.

[Operation of the embodiment]

Referring to FIG. 2, the operation of this embodiment will be explained.

In the figure, the open shelf board 19 is connected to the wire spring 3
9, it is supported by a tension rod 37 that is resiliently rebound in the counterclockwise direction. In this case, the shelf board 19 and the tension rod 37 are in a substantially vertical state.

In this state, when the shelf board 19 is turned counterclockwise, the pivot shaft A resists the spring 39 and rotates the support member 17.
It moves in the long hole 35 in the horizontal direction (in the direction of the arrow) and becomes in the state shown by the dashed line in the figure. In this state, when the shelf board 19 is further turned counterclockwise, the tension rod 37
rotates clockwise around the pivot A, and the pivot B moves obliquely downward within the elongated hole 33 of the guide plate 31. When the tension rod 37 becomes horizontal, the pivot A moves horizontally within the elongated hole 35 (in the opposite direction of the arrow) due to the elasticity of the spring 39, and returns to its original state (the axis A when the shelf board 19 is opened). state). In the figure, the horizontal state, ie, the closed state, of the shelf board 19 is indicated by a two-dot chain line.

In addition, when opening the closed shelf board 19, the operation is opposite to that when closing the shelf board 19 described above.

[Description of other embodiments]

FIG. 4 shows another embodiment of this invention, in which a separate support column 51 is provided in the center of the frame 11, and this support column 51 is provided separately at the center of the frame 11.
Shelf boards 19, 19, . . . are installed on both sides of 1.

[Effects of Examples]

The pallet with shelves according to this invention includes a frame having a support member having elongated holes, and a required number of shelves pivotably supported to the frame so that the support member is on the side. a guide plate having a long hole installed on the side surface of the shelf board, and a tension rod having a pivot axis A and a pivot axis B at both ends, and the pivot axis A of the tension rod corresponds to the length of the support member. The tension rod is fitted into the hole in a swingable and movable manner, and the tension rod pivot B
is fitted into the elongated hole of the guide plate so as to be swingable and movable, and further, the swinging of the tension rod is appropriately repelled in the direction of opening the shelf board by an appropriate repelling means, The appropriate resilient means comprises a wire spring that is fitted into the pivot shaft A of the tension rod and has one end fixed to the support member and the other end fixed to the tension rod.

In other words, in the pallet with shelves according to this invention, the tension springs do not protrude to the sides of the shelves as in the conventional case, so even if multiple shelves are installed on the frame at short intervals, the lower shelves will not swing. The shelf board does not come into contact with the spring when the shelf board is moved, and as a result, the shelf board can swing smoothly, and the generation of noise caused by contact between the shelf board and the spring, which conventionally occurs, is prevented.

The practical value of such a device is enormous.
