Description

[Detailed Description of the Invention] This invention relates to an upright device that is attached to the back side of a blackboard or other plate-like object (hereinafter referred to as a board) and stands up the board at a certain angle.

(Disadvantages of conventional products) The legs commonly used in the past for standing up boards are a method in which legs are pivotally attached to the back of the board, and when the board is set up, the legs are opened at a predetermined angle and fixed. However, the legs have to be thicker due to the structure, and accessories such as fixing devices are required, which increases the weight.

(Purpose of the present invention) The present product was devised for the purpose of reducing the protruding distance from the back surface of the board, making it as flat as possible, making it convenient to carry and move, and reducing the overall weight.

(Structure of the invention) The present product includes a straight shaft, a guide rod which is bent so that both ends of the shaft differ by 90 degrees in planes including the shaft, and a shaft portion of the shaft. It is comprised of two upper and lower mounting brackets that are inserted and held and that lock the tips of the guide rods, and a V-shaped support leg whose ends are fixed near the ends of the two guide rods.

(Example) The implementation product of this proposal will be explained with reference to the diagram.

Reference numeral 1 denotes a board, 2 the back surface of the board, and a main device erecting device 3 is fixed thereto by two metal fittings 4 and 5.

6 is a linear shaft made of a pipe or a rod-shaped body, both ends of which are bent by 180 degrees, and the surface thereof is bent by 180 degrees.
The guide rods 7 and 8 are formed with a difference of 90 degrees.

The length ratio of the shaft rod 6 and the guide rods 7, 8 is approximately 1/2, but the length ratio is changed depending on the mounting position of the mounting brackets 4, 5, the length of the leg drawer, etc. .

Reference numerals 7A and 8A indicate tip portions, and 9 indicates a V-shaped supporting leg, both ends of which are fixed near the end of the guide rod 10 and 1, respectively.
1 has been done.

The mounting brackets 4 and 5 are constructed with a width that allows the shaft rod and guide rod to be inserted at the same time, and the mounting position on the back of the board is as shown in Fig. has been done.

The above-mentioned product is in the state shown in FIG. 1 when stored or transported.

When the board is to be used in an upright position, the V-shaped support leg 9 is raised in the direction of the arrow A, the tip 8A of the upper guide rod 8 is separated from the metal fitting, and further rotated in the direction of the arrow B.

From this state (Fig. 2), pull down in the direction of arrow C (state of Fig. 3), position the tip 7A of the lower guide rod 7 below the lower mounting bracket 5, and further rotate it in the direction of D in Fig. 4. .

Next, the support leg 9 is pushed up in the direction of arrow E in FIG. 5, and the tip 7A of the lower guide rod 7 is inserted into the lower edge of the lower metal fitting 5.

Reference numeral 10 denotes a notch provided on the lower edge of the metal fitting 5, which engages with the side surface of the support leg 9 to prevent rotation of the support leg and ensure upright stability.

(Effects) The board erected in this way will look like the one shown in Figure 6 and can be used both indoors and outdoors, and can be easily folded into the folded state shown in Figure 1 by performing the opposite operation to the above. It becomes easier to carry.

[Brief explanation of the drawing]

Figure 1 is a rear view of the board with the proposed device attached. Figures 2 and 5 are partial rear views for explaining the operating sequence of the proposed device. Figure 6 is a side view of the board in an upright state. Figure 7 is a cross section of the fitting showing the position of the shaft within the fitting. 4 and 5 are metal fittings, 6 is a shaft rod, 7 and 8 are guide rods, 9
is a supporting leg.
