Description

[Detailed description of the invention] <Industrial application field> The present invention relates to the improvement of pallets (hereinafter referred to as frame pallets) that are used for moving and storing cargo, etc. by providing side frames on metal pallets. be.

<Prior art> Frame pallets are, for example,
As shown in Utility Model No. 57-11726, etc., side frames made of metal supports are attached to a square metal frame base, and the upper beams of the side frames are connected in a U-shape with an open front.
It has a simple structure, and when not in use, it can be stored nested and stacked without being folded, saving storage space.

<Problems to be solved by the invention> In these conventional frame pallets, an intermediate support can be provided at the back of the side frame, but because the left and right side frames are stacked in a nested manner when not in use, For example, in flexible containers filled with powder,
In some cases, the load collapses and protrudes outside the left and right frames, making it unsuitable for transportation and storage, and its use has been limited to rigid cargo.

In order to solve the above-mentioned drawbacks, the inventor believed that it was necessary to provide a support between the left and right side frames and to support the cargo with this support, and that this intermediate support could be used when stacking pallets in a nested manner when not in use. They came up with the idea that it would be sufficient to make the pallet slide so as not to interfere with the stacking of pallets, leading to the completion of the present invention.

<Means for Solving the Problems> Thus, according to the present invention, the front columns 2, 2 are attached to both ends of the front frame of the square frame 1 so that the distance between the inner surfaces of the two columns is equal to the distance between the inner surfaces of the square frame 1. The rear struts 3, 3 are erected so as to be larger than the width, and are in contact with the rear surface of both ends of the rear frame.
, the upper ends of both rear columns are connected by a back frame 4, each end of the back frame and the upper end of the front column are connected by an upper frame 5 provided with an upper guide part 6, and between the back frame and the rear edge of the rectangular frame. At least one back support 7 is fixedly installed at the bottom of the rectangular frame, girder legs 8 are provided on the bottom surface of the rectangular frame in parallel to the side edges inside the side edges, and lower guide parts 9 are attached to both side frames of the frame. and the upper end between the frame side frame and the upper guide part,
There is provided a frame pallet characterized in that it is provided with a movable column 10 whose lower end slides through the lower guide part while maintaining verticality.

An embodiment of the present invention will be described based on the drawings.
FIG. 1 shows a perspective view, and a rectangular frame 1 is formed by assembling square pipes into parallel crosses, and in this embodiment, a bottom plate 11 is attached to the frame. Note that depending on the type of cargo, only a frame may be used without providing a bottom plate.

Front supports 2 are erected on both ends of the front frame of the rectangular frame base 1, and the distance between the inner faces of both supports is wider than the width between both side edges of the rectangular frame base 1. Rear supports 3 are erected abutting slightly inward rear faces of both ends of the rear frame, and both upper ends of both rear supports are connected to a back frame 4, and each end of the back frame is connected to the upper end faces of the front supports and an upper frame 5 via pieces 16, forming a U-shaped upper frame with an open front and a step. A back support 7 is fixed between the back frame and the rear edge of the rectangular frame base, and beam legs 8 are fixed to the lower base surface of the rectangular frame base 1, inside the side edges and parallel to the side edges, the height of the legs is set so that the claws of the forklift can enter and exit, and the rear ends of the beam legs are connected to the rear supports. By providing pillars at specific positions on such a square frame base, making the upper ends of the pillars into a U-shaped upper frame, and providing beam legs on the inside of the frame base, frame pallets can be stacked on top of each other in tiers, and when not in use, the square frame base of the upper frame pallet to be stacked can be inserted from the front in a nested manner through the front pillars of the frame pallet below.

That is, since the distance between the rear columns 3 and 3 and the distance (width) between both sides of the rectangular frame 1 are smaller than the distance between the front columns 2 and 2, the rear sections of the frame pallets to be stacked (rear columns and rear Pass the part of the square frame connected to the column from the front of the lower frame pallet between the front columns 2 and 2, and insert the legs of the upper frame pallet onto the square frame of the lower frame pallet. They can be stacked in a nested manner by placing them on.

Next, as shown in FIG. 2A, a guide groove is bored in the lower bottom surface of the square pipe of the upper frame 5 to form an upper guide part 6, and the circular pipe of the movable strut 10 is inserted into this guide groove. The upper end formed into an oval shape fits loosely.

Note that the upper frame 5 is horizontally installed at both ends of the front support column 2 and the back frame 4 via pieces 16, but when stacking, due to the height of the girder legs 8, the upper frame pallet is always placed on the upper side of the lower frame pallet. Since they are placed above the frame 5, they can be stacked smoothly. The side frames 12 of the rectangular frame 1 have a downward U-shaped cross section, and a stopper 14 is provided in the middle between the bottom plate 13 of the girder leg, and a guide rod is provided between the stopper and the tip of the girder leg. is installed inside the lower guide part 9.
As shown in FIG. 2B, a slide tube 15 provided on the edge of a flat plate fixed to the lower end of the movable column 10 is loosely fitted into this guide rod.

In addition, as for the structure of the lower guide part, the guide rod may not be installed inside the U-shaped frame of the side frame, but may be installed exposed under the side frame, and the upper guide part may also be installed parallel to the bottom of the upper side frame. Alternatively, a guide rod may be attached, and a slide tube provided at the upper end of the movable column may be loosely fitted into the guide rod.

In addition, as another example, the structure of the frame pallet is as shown in FIG. The upper frame is formed into a U-shaped frame of the same size as the rectangular frame base and without a step through a piece 16 provided at the upper end of the front support, and the girder legs 8 are installed inside the inner surface of the rectangular side frame. , whose rear end coincides with the inner surface of the rear frame, and which is provided with the above-mentioned upper guide part, lower guide part, and an intermediate movable column that slides through these. can be mentioned. With this frame pallet, when loading cargo and stacking frame pallets vertically,
It can be placed with the lower surfaces of the three peripheral edges of the upper rectangular frame in contact with the three sides of the U-shaped upper frame with no steps below.
This has the advantage that a very stable stacked state can be obtained.

<Function> When a flexible container filled with cargo that is prone to collapse, such as powder or granular material, is placed on the frame pallet of the present invention, by positioning the movable struts in the middle of the side frames, the fixed back struts, Together with the corner supports, the cargo is enclosed in a cage to prevent the cargo from collapsing and pushing outward.

In addition, when the upper pallet is nested on top of the lower pallet when not in use, the movable struts come into contact with the front struts of the lower pallet, slide through the upper guide section and the lower guide section, and cause an accident. Since it touches the frame pallet, it can be stored like a conventional frame pallet.

In addition, if the movable column cannot slide so as to touch the front column, when stacking the upper frame pallet, the corners of the rectangular frame base of the upper pallet will hit the column and it will not be possible to insert it only halfway. The support structure of the present invention allows for smooth storage.

<Effects of the invention> According to the invention, frame pallets can be stored in a nested manner as in the conventional method when not in use. It can now be applied to the movement and storage of cargo that would otherwise be impossible.
This greatly expands the uses of frame pallets. Furthermore, there is the advantage that conventional frame pallets can be easily modified in accordance with the present invention.
