Description

[Detailed explanation of the idea] The present invention relates to a support device for bulletin boards, blackboards, etc.

In other words, supporting legs can be attached in an inverted T-shape or L-shape to the bottom end of a vertical column that supports bulletin boards, blackboards, etc., and the support legs can be stably supported on the floor of a room sufficiently far from the wall. It can be used to support bulletin boards, etc. close to the wall, and both or one of the two supporting legs, which can be formed identically, can be attached to the bottom of the column reliably and robustly, and can be easily attached and detached. The present invention provides a compact structure that can be easily mounted, easily manufactured, and can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a side view of the whole, with vertical pillars B made of square pipes on both sides of the vertical bulletin board C or blackboard.
The upper parts of B are joined together and connected to each other via mounting brackets 8, 8, and both horizontal support legs A and A facing in opposite directions are attached to the front and back of the lower parts of both branches B, and one of them is It is something that can be stolen by making it removable.

Both support legs A, A are made entirely of aluminum and have the same shape, and are formed so that the entire inside in the long plane direction is hollow with the bottom surface 9 flush with each other, and the inside is open at the bottom and has a center hole. Ribs 10 extending in the longitudinal direction and extending horizontally at intervals in the longitudinal direction are formed, and one end is high and the other end is low, and the other end is used to attach casters 11 or a rubber base, etc. The hole 12 is vertically penetrating, and one higher end is the proximal end, which has both mountings that can be connected from the outside to both sides 1, 1 of the support column B. The surfaces 3 and 4 are shaped to extend in parallel from both sides, and the inner spacing S1 of both mounting surfaces 3 and 4 in the plane is somewhat smaller than the spacing S2 on the tip side, and one mounting surface 3 is the upper half and the other mounting surface 4 is the lower half, and the lower edge 3a of the mounting surface 3 and the upper edge 4a of the mounting surface 4 intersect in an X shape on the side surface. The partitions are formed in an inclined shape, and a long hole 13 is formed in the center of the mounting surface 3, and a round hole 14 is formed in the center of the mounting surface 4.

In addition, both mounting surfaces 3 at one end of the supporting leg A,
4 is formed with an upright surface 5 on the upper side that is orthogonal to both the mounting surfaces 3 and 4 and can face the front and rear surfaces 2 of the support column B. It is formed on a receding slope, and in the horizontal direction at the center of the upright surface 5 there is a support column B at the tip.
It is formed by inserting a screw 6 that can come into contact with the front and rear surfaces 2 of the.

Round horizontal holes 15 and 16 passing through in the direction of both sides 1 and 1 are formed in the upper and lower parts of the lower part of the pillar B, respectively,
A nut 17 is installed at the other end of the screw rod 7 which can be inserted into the round hole 14, the elongated hole 13, and the horizontal hole 15, 16 and has a head 7a at one end so as to be screwed therein.

In the figure, 18 indicates a floor surface, and 19 indicates a wall surface.

Therefore, when attaching both supporting legs A, A to the lower part of both supporting columns B, B facing in the front-rear direction, as shown in FIGS. Fit the support legs A and A so that the mounting surfaces 3 and 4 are connected to each other vertically, and place the double threaded rods 7.7 above and below the long hole 13 in the mounting surface 3, the horizontal hole 15.16 in the support column B, Insert them into the round holes 14 of the mounting surface 4, respectively, and screw the nuts 1717 onto the ends of both threaded rods 7, 7 to attach the ends of both support legs A, A to the support column B, and then tighten the respective screws 6. , 6 are advanced and retracted, the tips of the screws 6 abut against the front and rear surfaces 2 of the column B, and both supporting legs A, A are in a state of rotation around the lower threaded rod 7, and both supporting legs A, A, A
By touching the floor, it is possible to correct the support column B so that it stands upright.

In this way, both supporting legs A are placed in front and behind the bottom of the pillar B.

By attaching A in an inverted T shape, bulletin board C can be stably supported.

Also, remove the upper and lower nuts 1 17, move the screw rods 7 a little and remove them from the round holes 14, 14 on the mounting surfaces 4, 4, pull out only the rear support leg A, and tighten the screw rods again. 7,
When nuts 17 and 17 are screwed onto the tips of 7, the L is attached to the support column B with only the front supporting leg A attached.
By operating the screw 6, the angle between the pillar B and the supporting leg A can be corrected, and the bulletin board C can be supported close to the wall surface 19 as shown in FIG. .

In this way, the present invention has two horizontal support legs facing in opposite directions at the front and back of the lower part of a vertical pillar made of square pipe that supports a vertical bulletin board, blackboard, etc. On both sides of the support leg, there are parallel extending surfaces that can be connected from the outside to both sides of the lower part of the column, and the upright surface of the end of the support leg is perpendicular to both the supporting surfaces. Insert screws that can touch the front and rear surfaces of the support strut, and attach and remove screw rods, pins, etc. to the side of the support strut so that both the supporting legs are placed up and down on one side. Because of this structure, supporting legs can be installed in an inverted T-shape or L-shape at the bottom end of the vertical pillars that support bulletin boards, blackboards, etc. It can be stably supported on an empty floor, or when a bulletin board or the like is placed close to a wall as a screen, it is possible to install the support legs on the front side, that is, on one side, and it can be supported well and save indoor space. It can be widely used, and can be mounted sufficiently close to a small support by aligning the two supporting legs vertically, and can be reliably and robustly mounted using threaded rods or screws. The angle between the supporting leg and the column can be corrected by operating the screws in contact with each other, and the supporting position can be set well. It also has the advantage of being easy to manufacture and having a compact overall structure that can be conveniently implemented.
