DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a display panel 10 is supported on a support 12 via a connecting structure according to the present invention.

The illustrated display panel 10 comprises an elongated plate-shaped main body 14 for accommodating and holding paper sheets or films (not shown) to which explanations of plants, animals and the like are attached, and a transparent cover 16 thereof. . In the illustrated display plate 10,
The front surface and the back surface are defined by the back surface of the main body 14 and the front surface of the cover 16, respectively. The illustrated display panel 10 is formed by molding a plastic material.

FIGS. 3 and 4 show the support state of the display panel 10 when the display panel 10 is viewed from the back side and the front side, respectively.

The display panel 10 is not limited to the illustrated example. As another example, there is a single plate made of, for example, plastic or metal. In the case of a single plate, both surfaces define the front and back surfaces of the display panel, respectively.

The column 12 is made of, for example, a wire or a pipe made of metal or plastic as shown in the figure.

The connection structure according to the present invention provides a main body 1 of a display panel.
4, two holes 18, the display panel 10 and the support 12
And a connecting member 20 for connecting the two to each other.

Each of the holes 18 is a recess opening on the rear surface of the display panel 10 as a whole, and is a hole penetrating through the main body 14 as a part of the display panel.
Of course, each hole 18 can consist of a recess that does not penetrate the body 14.

The holes 18 are provided at the center in both the longitudinal direction of the display panel 10 and the width direction perpendicular thereto. Instead of the illustrated example, the holes 18 can be arranged at a distance from each other. In addition, the number of holes 18 to be installed can be single or three or more, and the installation location can be arbitrarily determined.

Each of the illustrated holes 18 is a long hole having an elongated rectangular opening shape extending in the longitudinal direction and the width direction of the display panel 10, respectively, and is generally continuous with each other to form a cross-shaped opening shape. are doing. According to this, the display plate 10 can be supported vertically by inserting the later-described claw portion 30 of the connecting member 20 into the horizontally long hole 18.
The display panel 10 can be supported horizontally by inserting it into the horizontally long hole 18. The holes 18 may extend in different directions other than directions perpendicular to each other, instead of the illustrated example.

Each hole 18 has a plurality of projections 22 provided on a wall surface defining the holes 18.

A typical description of the horizontally long hole 18 will be described. The hole 18 has two pairs of upper and lower convex portions 22. The two pairs of protrusions 22 are arranged at an interval in the width direction of the display panel. The upper and lower convex portions 22 forming a pair are respectively
The rectangular shape having the opening shape of 8 extends along a pair of upper and lower opening edges opposed to each other and protrudes toward one other opening edge.

That is, each pair of projections 22 is arranged close to the opening surface 24 of the hole 18 forming a part of the back surface of the display panel 10. Each projection 22 is formed of a wall having a small thickness and a low height, and has a length (a length in a width direction of the display panel).
Is preferably substantially equal to the length dimension of the claw portion 30 of the connecting member 20 described later.

As shown in FIG. 2, the connecting member 20 includes an elongated block-shaped main body 26 and a pair of protrusions 28 arranged on both sides of the main body 26. Main body 26 and double projections 2
The sum of the lengths of the lengths 8 is slightly smaller than the length of the hole 18 (length in the width direction of the display panel). For this reason,
Both protrusions 28, more specifically the claw portions 30 described later, can be inserted into the holes 18. The connecting member 20 is made of, for example, a plastic material.

The body 26 has an open bottom end hole (not shown) that can receive and frictionally engage the end of the post 12. Therefore, the end of the support 12 is connected to the main body 26.
The connecting member 20 is inserted into the hole of
2 can be attached. The illustrated body 26 has a rectangular cross-sectional shape. However, the cross-sectional shape of the main body 26 is not limited to this, and can be arbitrarily determined.

Each of the projections 28 includes a pair of claws 30 arranged at an interval above and below as viewed in FIG. 2, and a small block-shaped base 32 connected to the claws 30.

The two projections 28 are respectively in contact with the opposing side surfaces of the main body 26 and are therefore spaced from one another.

The main body 26 has a pair of shafts 36 projecting from both side surfaces thereof. Further, both projections 28 have two holes 34 provided in these base portions 32, respectively.
The two projections 28 are attached to the main body 26 through a relatively firm fit between the holes 34 and the two shafts 36 of the main body 26. Thereby, both projections 28 can be rotated around the axis of each shaft 36, that is, the axis parallel to the straight line orthogonal to the column 12.

A pair of claws 30 in each projection 28 are directed upward and downward, respectively.

The two pairs of claws 30 can be inserted into the holes 18, and when inserted into the holes 18, each of the claws 30 abuts on each of the projections 22 of the hole 18. Next, due to the elastic deformation of each of the claw portions 30 and each of the protrusions 22 due to the abutment, each of the claw portions 30 gets over each of the protrusions 22, and each of the protrusions 2.
2 locks it behind.

At this time, the base 32 connected to the claw 30 is
Opening surface 24 of hole 18 defining a part of the back surface of display panel 10
(See FIG. 3). Accordingly, the projection 28 is fixed so as not to move with respect to the display plate 10 in the insertion direction of the claw portion 30.

By inserting the claw portion 30 into the hole 18,
The display panel 10 and the support 12 can be firmly and reliably connected via the connection member 20.

Moreover, the operation of inserting the claw portion 30 into the hole 18 can be easily performed. Further, the claw portion 30 can be pulled out from the inside of the hole 18, whereby the display panel 10 can be replaced or the like.

The projections 28 can be connected to each other, for example, by a thin band 38 connected to the top of both bases 32. The band 38 extends beyond the top 40 of the body 26 of the connecting member.

The two projections 2 around the axis 36 with respect to the body 26
It is desirable that the shape of the top 40 of the main body 26 be a semi-cylindrical surface so that the band 38 is not easily hooked on the top 40 of the main body 26 when the display panel 10 is adjusted in angle by rotating the display panel 8.

As for the connecting member 20, instead of the illustrated example, the main body 26 and the two projections 28 may be integrated. Further, the two projections 28 may be a single projection connected to each other.

As shown in FIGS. 5 to 8, in addition to the plurality of protrusions (one protrusion) 22 on the wall surface of the hole 18, a plurality of other protrusions 42 are provided. Instead of the projection 28, a bar-shaped portion 44 can be used.

As shown in FIG. 1, two pairs of one convex portion 22 are arranged for each of the vertical and horizontal holes 18. However, in order to avoid complication of the figures, in FIGS.
Only one protrusion 22 is shown for each of the vertical and horizontal holes 18.
In the example of FIG. 1, each convex portion 22 extends along the opening edge of the hole 18, but only extends along a part of the opening edge (the intersection of the vertical and horizontal holes 18). I have. Further, in the example shown in FIG. 1, the one convex portion 22 is
Are arranged on the front surface side of the main body 14 while being arranged on the rear surface side.

The other convex portion 42 is disposed on the front side of the main body 14 of the display panel. Two pairs of other protrusions 42 are also arranged in each of the vertical and horizontal holes 18 corresponding to the one protrusion 22.
However, two pairs of convex portions 42 of each hole 18 are disposed at both ends of each hole (elongated hole) 18, respectively, and two pairs of convex portions 42 are formed.
Are connected to the opening edges of the holes 18 facing each other.

On the other hand, the rod portion 44 of the connecting member is formed of a column and has a size that can be inserted into each of the holes 18, that is, a length and a diameter slightly smaller than the length and the width of the hole 18. The diameter of the rod-shaped portion 44 is a size that is sandwiched between the one convex portion 22 and the other convex portion 42.
When the rod portion 44 is pushed into the hole 18, the one convex portion 2
2 and is received between the one convex portion 22 and the other convex portion. Thus, the rod portion 44 is firmly and rotatably held in the hole 18.

The main body 26 of the connecting member connected to the rod portion 44
Is formed of a tubular body having the same outer diameter as the rod-like portion 44, and crosses the rod-like portion 44 at the center in the longitudinal direction. The end of the column 12 can be inserted into the main body 26 made of a tubular body.

In this example, the main body 26 is inserted into the hole 18 from the front side to the back side of the main body 14 of the display panel before the rod portion 44 is pushed into the hole 18 (see FIG. 5). Further, in this example, the main body 14 of the display panel and the cover 16 are separated from each other, and after the rod-shaped portion 44 is inserted into the hole 18, the cover 16 is attached to the main body 14 of the display panel, and the front side of the main body is fixed. Cover (see FIG. 6).

The rod portion 44 has a plurality of concave portions 46 provided at intervals in the circumferential direction thereof and capable of engaging with the other convex portions 42. More specifically, the concave portion 46
It is formed of a groove provided at each end of the rod portion 44 and extending in the axial direction thereof. On the other hand, the other convex portion 42 is a semi-cylindrical tip portion 4.
8 (see FIGS. 7 and 8). Bar-shaped groove 46
Is engaged or engaged with the other convex portion 42 at the distal end portion 48 thereof. With this engagement,
The rotation of the rod portion 44 between the two convex portions 22 and 42 is restricted, and the angle of the main body 26 (and thus the support 12 connected thereto) connected to the rod portion 44 with respect to the display plate 10 is maintained. This angle applies a rotational force to the rod portion 44 via the main body 26 of the connecting member so that the groove 4 engages with the distal end portion 48.
It can be changed by changing 6 to another groove.

In the illustrated example, the other convex portion 42 is provided with an arc surface 50 that is in contact with the peripheral surface of the end portion of the rod portion 44. The arc surface 50 makes the rotational movement of the rod portion 44 about the axis more smooth.
