  However, in the case of the foldable display panel with a rack as described above, the rack is erected at an intermediate position in the height direction between the panel and the legs or the front and rear panels, and a space is provided between the rack and the ground or the road surface at the placement site. The height of the center of gravity when placing the weight is increased by the height of the space, and the display panel is subject to strong winds, the wind of large trucks, the effect of wind in steep places, etc. There is. Further, there is a high danger to workers, passers-by, and passing vehicles due to the display panel falling or being blown away, and there is a problem such as damage to the display panel.

  In addition, when the front and rear panels and the back side are legs, the ground surface is relatively stable when the ground surface is flat, but when the ground surface is uneven, or when the slope surface is inclined, the grounding of the panel and legs is It is unstable.

  In recent years, on the display surface of the display panel, a plastic prism lens type reflection sheet, a capsule lens reflection sheet, a high-brightness reflection plate, or the like is provided on the display surface of the display panel to enhance the visibility of passers-by as shown in Patent Document 1. Prevention of damage to the display surface is particularly important because expensive and easily damaged reflectors are used.

  In addition, since a foldable display panel stores and transports a large number of display panels in a folded state, the degree of damage to the display surface and collapse of a load during transportation poses a problem.

  Further, the display panel as described above is arranged in an inverted V-shaped chevron with respect to the ground plane, so that the display panel is relatively stable, but against a strong wind or a gust against the panel surface or the inner surface. In addition to being susceptible to wind pressure and inevitable danger of falling, particularly large ones are heavy and inconvenient for installation, storage and transportation.

  The mechanism of the present invention for solving the above-mentioned problem is a self-supporting display panel having a display panel 1 on a front surface side, which can be opened and closed by folding back and forth, and wherein the panel 1 is folded. In a display panel provided with a weight mounting rack 7 that is folded and opened and closed on the back side of the panel 1 as it is opened and closed and connected to the lower end side of the panel 1, the rack 7 that is extended when the panel 1 is opened is grounded. And a mechanism for holding the panel 1 in an independent posture.

  Secondly, the rack 7 is formed in a lattice shape with pipes having a rectangular cross section, and the pipes abut on the lower rear surface of the panel 1 in a state where the panel 1 is folded, so that the front and rear surfaces are held in a substantially parallel state. It is characterized by a mechanism.

  Third, a plurality of protection members 18 are protruded and attached at predetermined intervals at positions not obstructing the display portion on the front side of the panel 1 having the display surface, and the plurality of folded display panels are overlapped. In this case, the protection member 18 serves as a spacer for another display panel, and a mechanism for preventing the other display panel from contacting the surface of the panel 1 is provided.

  Fourth, the protection member 18 is formed of an elongated member along the upper and lower or left and right periphery of the panel 1, and is attached to an end portion of the periphery.

  Fifth, the protection member 18 is made of rubber or a plastic member having elasticity with a channel-shaped cross section that is open to the front, and when the display panels are stacked, the channels are engaged with each other to be a regulating member that regulates horizontal movement. It is characterized by.

  Sixth, a protection cover 8 that covers the peripheral edges at the left and right ends of the panel having the display surface is provided.

  Seventh, a cutout window 23 is formed in a margin portion on the outer peripheral side of the display unit 9 on the display surface of the panel 1.

  Eighth, the display surface is formed of a prism lens type or capsule lens type reflection sheet or a reflection sheet 1a made of a high-brightness reflection plate, and the display section 9 side of the cutout window 23 is made to follow the outline of the display section 9. It is characterized in that it is formed leaving a cutout portion 24 of a predetermined width between the cutout and the display section 9.

  According to the display panel of the present invention configured as described above, the weight is placed in a state where the rack is extended and grounded within the lower end of the display panel that is self-supporting at the placement site, so that the center of gravity is lowered. In addition to being stable and improving the posture holding effect, the weight itself is supported by the ground surface, and the contact with the ground side via the rack, even if there is some unevenness or inclination, there is little lateral displacement and it is suitable for contact with strong winds and heavy equipment etc. It is easier to maintain a stable posture.

  In addition, since the rack is in the folded state between the front and rear panels or between the panel and the legs, this thickness setting makes the front and rear surfaces almost parallel planes, so stability is good when stacked, and loading and unloading with less load collapse The work is easy and safe.

  Furthermore, since the protective member is provided protruding from the display surface side of the panel, deterioration of the display due to damage to the display surface during stacking and damage to the expensive reflective sheet or reflective plate can be prevented, and an elastic member is provided for the protective member. By using or stacking by meshing channel-shaped cross sections, there is an advantage that side slip between display panels can be prevented and collapse of a load during transportation can be prevented.

It is a principal part expanded side sectional view in the state where the display panel was arrange | positioned on the floor surface. It is a principal part side sectional view in the state where the display panel was piled up. It is a front view showing other embodiments of the display panel of the present invention.

  1 to 3 show an embodiment of a display panel according to the present invention. FIG. 1 is an overall perspective view of the display panel. A front or rear rectangular or square aluminum plate 1 can be pivotally opened and closed at an upper end. A hinge-like joint member 2 made of an extruded aluminum product is connected and fixed by a fixing tool 3 such as a screw or a rivet so as to be openable and closable. Alternatively, a U-shaped cross section leg 4 made of a plastic material is externally fitted and fixed with a fixing tool 6 such as a screw or a rivet.

  The panel 1 is stably disposed on the ground surface in an inverted V-shape when viewed from the side in an open V-shape. In a folded state, a rack 7 that is housed in a state of being folded together with the panel 1 is provided on the inner side of the panel 1 in a connected state.

  A reflective sheet 1a made of plastic is adhered to the entire surface of the panel 1, and the reflective sheet 1a is, for example, a diffuse reflection type called a prism lens type reflection sheet, a capsule lens type reflection sheet, or a high brightness reflection plate. An end cover 8 having an L-shaped cross-section made of a band-shaped aluminum member covering the end surface and the end surface of the reflection sheet 1a is provided at both left and right ends, which is highly visible to drivers and other passers-by regardless of day and night. Are fixed with screws or rivets. The end cover 8 is for protection of the reflection sheet 1a, reinforcement of the end of the panel 1, and safety of an operator at the time of handling. Further, a display portion 9 showing an arrow indicating a traffic direction and a shadow thereof is printed and displayed at a substantially central portion of the reflection sheet 1a.

Figure 2 is the joint member 2, overlap the slide wall 2a-1, 2b-1 of the arc-shaped cross section partially in side view as shown in Figure 3, the pivot point 2c on the center of the arc (the axis O ₁₎ A pair of joint pieces 2a, 2b having skirt portions 2a-2, 2b-2 extending downward from the outer ends of the slide walls 2a-1, 2b-1 and attaching the upper ends of the front and rear panels 1. A known member is used. Reference numeral 11 denotes a leaf spring-like biasing member that applies an opening / closing load to the joint member 2 to maintain the open or closed posture.

  In the center of the joint member 2, a handle 13 bent in a gate shape in a front view and provided with a hook 12 in the panel 1 is inserted vertically so as to be able to move up and down freely and without hindering the opening and closing rotation of the joint member 2. Have been. Further, a pair of front and rear rubber covers 14 are attached to the left and right ends of the joint member 2 so as to cover the end peripheral surface and the end surface.

  Hanging portions (strings) 17 of weights 16 such as sandbags are suspended from the hooks 12, and the weights 16 are placed on the racks 7 as described later so that the racks 7 are fully extended and grounded on the ground surface. Thus, the fixing force and stability of the display panel to the ground plane are improved.

  At the upper and lower ends of the exposed surface of the panel 1, as shown in FIGS. 1 and 2, a protection member 18 having a channel-shaped cross section opened toward the front surface and made of an elongated elastic member in the left-right direction is attached. In this example, the panel 1 is fastened and fixed to both left and right ends of the panel 1 with vise-shaped clips 19. A mounting plate 21 made of a band-shaped metal plate is accommodated inside the channel-shaped cross section of the protection member 18, and the protection member 18 is mounted and fixed by clipping both ends of the mounting plate 21 to the ends of the panel 1. ing.

The rack 7 is constructed by combining front and rear frame bodies 7a and 7b, which are formed by assembling a square cross section of aluminum pipe material in a lattice shape, at a front and rear center pivot point (axial center O ₂ ) so as to be rotatable. Each of the front, rear, left and right ends of the front and rear panels 1 is rotatably supported by the mounting member 22 between the inner surfaces of the lower ends of the front and rear panels 1 via a rotation fulcrum (axial center O ₃ ).

Rack 7 by this mechanism, the panel 1 around the axis O ₁ in the direction of arrow a by rotating the frame body 7a about the axis O _3, and 7b in the direction of the arrow b, the open leg state Can be folded to the closed state, and the legs can be opened by the reverse operation. When the panel 1 is in the open state, the grids at the connection ends of the frame members 7a and 7b of the rack 7 are not rotated any further by a stopper mechanism overlapping with each other, but are fixed in a flat-plate extended posture and grounded on the ground surface.

  When the weight 16 is placed in this extended state, the rack 7 is firmly and stably held by the weight of the weight 16 in the extended position of the rack 7, that is, the open position of the isosceles triangle of the display panel in a side view, and strong wind pressure and other equipment The stationary posture can be maintained on the ground surface without falling or moving even in contact with the ground.

  When the front and rear panels 1 and the rack 7 are folded, the front and rear panels 1 are kept substantially parallel with the lower ends of the frames 7a and 7b abutting and overlapping as shown in FIG. The thickness of the frame bodies 7a and 7b is designed so as to be adjusted. Further, when a plurality of display panels are stacked in this folded state, as shown in the drawing, the open end of the channel-shaped cross section of the protection member 18 on the overlapping surface is in the channel of the protection member 18 of the other display panel. The channels are stacked in contact with the mounting plate 21 and in a state where the channel shapes are engaged with each other.

  Therefore, even in the stacked state, the surface of the panel 1 of each display panel is prevented from contacting the surface of another display panel or the uneven portion, and the printed display on the surface of the panel 1 is damaged by the contact and damaged by wear. Not even. In particular, when an expensive reflection sheet 1a such as a high-brightness reflection sheet is used for the display surface of the panel 1 as in the illustrated embodiment, the life of the panel 1 itself is protected by protecting the display unit 9 and the reflection heat 1a. It can be maintained for a long time and has a great economic effect.

  In addition, since the protection member 18 itself protrudes over the entire width from the surface of the panel 1, contact with at least the other members straddling both the protection members 18 is prevented, and as described above, the elastic protection member has elasticity. By superimposing the 18 on each other in a meshing state, the external force applied to the panel 1 at the time of stacking is elastically dispersed, and the shock resistance is excellent, and the load of the display panel is prevented from slipping due to a side slip or a side slip. There are advantages that can be done.

  FIG. 4 is a front view of a folded display panel showing another embodiment of the present invention. In this example, a large display panel which is particularly susceptible to wind pressure is shown. In this display panel, a cutout window 23 having a shape corresponding to the margin shape is cut out in a margin around the display portion (arrow) 9 on the surface of the panel 1, and the outer periphery of the cutout window 23, particularly, the display portion 9 is formed. Between the cutout window 23 and the cutout window 23, an uncut portion 24 having a predetermined width is formed along a partial outline of the display unit 9.

  With the above configuration, the weight of the large display panel can be reduced, and since the cutout window 23 can be ventilated in the front-rear direction, the wind pressure such as a gust can be avoided to prevent the display panel from being blown or falling due to a gust. It is also possible to see through a part of the scenery on the opposite side of the display panel, which is useful for preventing accidents during traffic. In addition, the uncut portion 24 on the outer periphery of the display unit 9 has an effect of enhancing the visibility by making the display unit 9 stand out at the time of light irradiation.

  The other configurations in FIG. 4 are common to those shown in FIGS. 1 to 3, and the same reference numerals indicate members common to those in the above-described example. However, in this example, the protection members 18 at the upper and lower ends of the exposed surface of the panel 1 are fixed together with the mounting plate 21 together with the mounting plate 21 by the fixing tool 20 such as a screw or a rivet instead of the clip 19. I do.
