Description

Detailed Description of the Invention (Industrial Application Field) The present invention is used to store printed circuit boards incorporated in various electrical and electronic devices and board materials used in other industrial fields (for example, panels used as building materials). More specifically, it relates to a storage frame that can accommodate changes in the dimensions of these plate materials.

(Prior art) As a storage box that can store printed circuit boards of various sizes in one box, for example,
``Electronic package storage case'' disclosed in Japanese Patent No. 26999 is well known. This invention consists of horizontal guide rules provided in parallel on both sides of a case body having a cover that can be opened and closed, and a guide rail placed at the end between the guide rails on both sides, into which the edge of the board of the electronic package fits into the opposing surface. By using a plurality of support plates each having a plurality of vertical grooves, electronic packages of various sizes can be stored at regular intervals.

(Problem to be Solved by the Invention) However, this invention can only continuously respond to dimensional changes in the length direction of the plate material, and when changing the width direction of the plate material, the receiving plate must be moved up and down in advance. Only step-by-step measures can be taken, such as using holes drilled in multiple stages to secure screws. Therefore, such a configuration is useful when transporting small quantities of electronic packages whose substrate sizes are standardized into several types for inspection or repair of electrical and electronic equipment. However, when the length and width dimensions of the plate material change frequently, and when large quantities are transported to a production line for electrical/electronic equipment or other equipment that requires assembly, extensive changes in specifications may not be necessary. It was impossible to use because it was possible.

(Means for Solving the Problems) An object of the present invention is to provide a variable storage frame that eliminates the drawbacks of conventional storage boxes that can only be accommodated continuously in the length direction of board materials as described above. We supply a storage frame with the following configuration. That is, an inner frame formed into a rectangular shape and fixed at a predetermined position within the outer frame is vertically movably attached to an outer frame formed in a box shape using a profile, and the inner frame is attached to the inner frame. Of the four sides of the inner frame, two opposite sides are fixed arms, and movable arms arranged parallel to the fixed arms are movable in the horizontal direction and can be fixed at desired positions. A frame body in which a fixed arm and a movable arm are provided in the base frame of the inner frame in correspondence with the fixed arm and the movable arm provided in the inner frame, respectively, and the fixed arm and the movable arm provided in the base frame include a plurality of fixed arms and a movable arm. It is characterized in that a lower corner support with vertical grooves is fixed, and an upper corner support with a plurality of horizontal and vertical grooves is hinged to a fixed arm and a movable arm provided on the inner frame.

(Function) The storage frame of the present invention has the above-described configuration, and the distance between the fixed arm and the movable arm, which fix the upper corner support and the lower corner support, is adjusted, and the base frame and the inner frame are By adjusting the distance between the frame and the lower corner support provided in the frame, a frame suitable for the board to be stored can be completed. When trying to store a board into the matching frame, first rotate the upper corner support by the action of the hinge to a position where the board can be inserted from above, and in this state, insert the board from the top into the lower corner. Insert the lower corner of the plate material into the longitudinal groove of the support. Next, the upper corner support is moved by the action of the hinge, and the upper corner of the plate is inserted into the lateral groove of the upper corner support, thereby storing the plate in the storage frame of the present invention.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing the overall structure of an embodiment of the present invention. The outer frame 1 is made of L-shaped steel or light metal and assembled into a box shape by welding or riveting. A long hole 3 in the longitudinal direction is formed in each of the pillars 2 at the four corners, and a projecting piece 4 extending outward from the L-shaped edge is provided over the entire length of the long hole 3. Butterfly bolts 6 are installed at the four corners of the inner frame 5 at positions corresponding to the elongated holes 3.
A hole (not shown) is formed through which the hole is inserted. Inner frame 5
is assembled by welding or riveting L-shaped members such as steel or light metal into a rectangular shape large enough to be inserted from the top of the outer frame 1, with long holes 7 formed on two opposite sides, and A projecting piece 8 extending outward (downward in the drawing) from the edge of the L-shaped member is provided over the entire length of the L-shaped member. A hole 11 through which a butterfly bolt 10 is inserted is provided near both ends of the movable arm 9 across the two opposing sides of the elongated hole 7 at a position corresponding to the elongated hole 7. In the base frame 12 of the outer frame 1, there are elongated holes 1 on two opposite sides corresponding to the elongated holes 7 formed in the inner frame 5.
It's dawning on 3. Since the base frame 12 is assembled with one side of the L-shaped member facing toward the outer frame, there is no need to intentionally provide a protruding side unlike the other L-shaped members with elongated holes 3 and 7. A backing plate 15 is fixed to both ends of the movable arm 14, which extends inside the two opposite sides of the base frame 12 with the elongated hole 13. ) is open.

And all the butterfly bolts 6, 10, 16 mentioned above
The butterfly bolts 6, 10,
A nut 17 is attached that can slide while being screwed together with 16.

Of the four sides of the L-shaped member constituting the inner frame 5, the two opposing sides that do not have the elongated holes 7 are fixed arms 18, and the fixed arms 18 have a plurality of horizontal grooves into which the corners of the plates 19 to be stored are fitted. An upper corner support 21 having grooves 20, 20, 20, . . . formed thereon is fixed via a hinge 22 such that the horizontal grooves 20, 20, 20, . Also in the movable arm 9 provided on the inner frame 5,
Similarly, the upper corner supports 21 are hinged. In addition to the movable arm 14, the base frame 12 includes a fixed arm 23, and a fixed arm 18 provided on the inner frame 5 parallel to the movable arm 14.
It is fixed in the corresponding position. The movable arm 14 and the fixed arm 23 are provided with a lower corner support 25 having a plurality of vertical grooves 24, 24, 24, .
24,... is fixed so that it is on the inside. In the illustrated embodiment, the upper corner support 21 and the lower corner support 25 are made of channel shapes to reduce weight, but from a functional point of view, it is of course possible to use solid square members. .

The storage frame of the present invention has the above-mentioned structure, and when used, the fixed arm 18 has the upper corner support 21 and the lower corner support 25 fixed in order to match the width dimension of the plate material 19 to be stored. , 23 and moving arm 9,
14 and tighten the butterfly bolts 10 and 16 to fix them to the inner frame 5 and the base frame 12, respectively. Furthermore, lower corner supports 2 are provided on the base frame 12 and the inner frame 5 to match the length dimension of the plate material 19.
The inner frame 5 is fixed to the outer frame 1 by adjusting the distance between the inner frame 5 and the upper corner support 21 and tightening the butterfly bolts 6. With the above steps, a frame suitable for the board to be stored is completed.

Next, the case where the plate is housed in the compatible frame will be explained with reference to FIG. 2.

First, the upper corner support 21 is rotated in the direction of the illustrated arrow by the action of the hinge 22 and moved to the position shown by the chain line. In this state, the vertical grooves 24, 24, 24, . . . of the lower corner support 25, .
Insert the lower corner of the plate material 19 into the hole. Next, by moving the upper corner support 21 from the position shown by the chain line in the figure to the position shown by the solid line by the action of the hinge 22, the lateral grooves 20, 20 of the upper corner support 21,
Insert the upper corner of the plate material 19 into 20, . . . .
As a result, the plate material 19 is stored in the storage frame of the present invention, and at the same time, the weight of the upper corner support 21 acts to hold the plate material in a fixed position. Therefore, even in this state, the upper corner support 21 will not come off from the plate material 19 and can be used as is if the vibration occurs when transporting a device that requires assembly between production lines. Like when transporting plates from one factory to another,
If there is a risk of receiving large vibrations due to passing over uneven roads outdoors, consider taking measures to restrict the movement of hinges attached to the upper corner supports to completely suppress the movement of the board. In this case, it is effective to connect the opposing upper corner supports with plate pieces.

FIG. 2 shows an embodiment in which the storage frame of the present invention is inserted into a box 26 that is open at the top and fits snugly into a box 26 for convenience in carrying and transporting printed circuit boards. It is something that A peripheral material 27 is attached to the top of the box 26, which serves both to prevent the storage frame from coming off and to reinforce the box 26. In this case, if the upper corner support, the lower corner support, the box 26, etc. are made of conductive material, parts such as ICs can be protected from static electricity when the mounted printed circuit board (electronic package) is transported. Since there is no need to worry about it being destroyed, its uses will be further expanded.

(Effects of the Invention) Since the present invention is a storage frame having the above-mentioned configuration, it can continuously respond to dimensional changes in both the length and width of the board, and the upper part can also respond to changes in board thickness. This can be achieved by preparing grooves with different widths formed in the corner support and the lower corner support and replacing them as necessary. Therefore, because we can accommodate orders with various specifications, we have been able to provide storage frames that can be used for a variety of purposes, from relatively small boards such as printed circuit boards to relatively large boards such as panels used as building materials. It is. Also,
Recently, the number of components mounted on printed circuit boards has increased, so components are attached to the entire flat surface of the printed circuit board, so it is not necessary to support the entire length or width of the printed circuit board as in the past. Such a printed circuit board could not be accommodated by a continuous long support. However, according to the storage frame of the present invention, since only the corners of the printed circuit board are supported, even printed circuit boards with many mounted components can be stored. This is not just limited to printed circuit boards;
It goes without saying that various types of plate materials have common advantages.

By the way, if the board material to be stored is long or heavy, it can easily fall over. Therefore, when a board is supported only by the lower corner supports, it is likely to be tilted, so when a number of boards are stored, it is necessary to use the many grooves in the upper corner supports. It becomes difficult to insert all the board materials. In such a case, handling can be facilitated by forming the upper corner support into small units having a plurality of grooves.
In other words, it is easy to operate by holding the several boards to be housed in the divided body upright with one hand and inserting them into the grooves of the upper corner support of the small divided body with the other hand. It's a good thing. Therefore, if this configuration is used, the practicality will further increase.
