Description

The present invention relates to a foldable traffic display panel applied to a display panel or the like commonly called an arrow board.

Conventionally, as shown in Patent Document 1, an arrow plate having display surfaces on both front and rear surfaces connected by connecting the upper ends of a pair of rectangular panels so as to be rotatable openable and closable together with the panels by a foldable rack is known.

Japanese Unexamined Patent Publication No. 2020-522

The above arrow plate has the front and rear panels opened in an inverted V shape, and when placed on the ground, the weight is placed on the rack in the extended state at the lower end of the inside, so that the wind pressure when passing strong winds or large vehicles Alternatively, it has the advantage of being able to maintain a stable posture capable of preventing falls, movements, collisions with other objects, etc. against other vibrations and the like. In addition, it has the advantage that it can be easily moved and carried regardless of whether it is in the open leg state or the folded state by holding the handle provided in the center of the upper end of the panel.

On the other hand, when folding the display panel when removing or moving from the open leg arrangement state, after lowering the weight, turn to either the left or right side of the panel and move the connection point of the frame in the center of the rack upward. Manual work (rotating the front and rear frames) is required, and at work sites where quickness is required at construction sites, disaster sites, emergency traffic guidance sites, etc., quicker removal and change of guidance direction (panel) It is necessary to replace or carry it by changing the direction indicated by the arrow.

The traffic display panel of the present invention for solving the above problems is a self-standing display panel that first has a display panel 1 on the front surface side and can be opened and closed by opening the legs back and forth. A rack 7 for mounting weights that folds and opens and closes on the back side of the panel 1 as the panel 1 is folded and opened is connected to the lower end side of the panel 1, and the rack 7 extended with the legs of the panel 1 open is self-supporting. In the display panel as a mechanism for maintaining the posture, the panel 1 is folded into the bottom surface of the rack 7 in an open leg posture with the panel 1 grounded, and by lifting the panel 1, the panel 1 protrudes downward from the bottom surface of the rack 7. The protruding end of the rack 7 touches the ground again to start the folding operation of the rack 7, and the attachment 24 for opening the leg that causes the panel 1 to be folded and operated from the open leg posture in conjunction with the folding operation is provided. It is characterized in that it is provided in the rack 7.

Secondly, the attachment 24 is retracted on the back side of the panel 1 when the panel 1 is folded.

Third, one end of a rod-shaped attachment 24 having a predetermined length is pivotally supported on the rack 7 side so as to be able to swing up and down, and when the panel 1 is lifted, the attachment 24 swings downward due to its own weight on the swinging end side of the rack. It is characterized by having a mechanism that projects downward toward the bottom surface side of 7.

Fourth, the display panel is a side-view inverted V-shaped chevron-shaped display panel in which the upper ends of a pair of panels 1 and 1 on the front side and the back side are connected so as to be openable and closable.

According to the display panel of the present invention configured as described above, the front and rear panels are automatically folded by raising the panel arranged in the open leg state by a certain height and lowering it again in the grounding direction. The work efficiency of the site is improved by eliminating the manual work of folding the rack to fold the panel for convenience of carrying and storage. In particular, if both the front and rear surfaces are panels, the above effect is even greater because manual work from the left and right opening sides is not required for folding the rack.

Furthermore, since the attachment for folding operation is stored on the back (inside) of the panel folded by folding, the protruding attachment does not interfere with other work or handling of the panel, and one end of the attachment can be used. Since the shaft is rotatably supported on the rack side, the attachment that hangs down by moving the panel back and forth when arranging the panel can be easily swung and stored in the bottom of the rack, and the attachment becomes an obstacle when arranging. There is no.

It is an overall perspective view of the display panel of this invention. It is an enlarged side sectional view of a main part in a state where a display panel is arranged on a floor surface. It is a side sectional view of a main part in a state where display panels are stacked. It is an enlarged side view which shows the self-folding mechanism of the display panel of this invention.

1 to 4 show one embodiment of the display panel of the present invention, and FIG. 1 is an overall perspective view of the display panel, in which the front and rear rectangular or square aluminum plate panel 1 can be rotated and opened and closed at the upper end. The upper end is connected and fixed to the hinge-shaped joint member 2 made of extruded aluminum with a fastener 3 such as a screw or a rivet so that it can be folded and opened, and the lower ends of both panels 1 have elasticity over the entire length. A grounding leg 4 having a U-shaped cross section made of aluminum or a plastic material is externally fitted and fastened with a fastener 6 such as a screw or a rivet.

The panel 1 is stably arranged on the ground surface GL in an inverted V shape in the side view in the open leg state, and extends between both ends on the lower end side of both panels 1 when the legs are open and touches the ground surface to open the legs. In the folded state, a rack 7 that is stored in a folded state together with the panel 1 is connected and provided on the inner surface side of the panel 1 while maintaining the state.

A plastic reflective sheet 1a is attached to the entire surface of the panel 1, and the reflective sheet 1a is, for example, a prism lens type reflective sheet, a capsule lens type reflective sheet, or a diffuse reflection type called a high-luminance reflector. A lens with high visibility for drivers and other passers-by is used regardless of day and night, and the end cover 8 having an L-shaped cross section made of a strip-shaped aluminum member covering the end surface and the end surface of the reflective sheet 1a at both left and right ends. Is fixed with screws or rivets. The end cover 8 is for the protection of the reflective sheet 1a, the reinforcement of the end of the panel 1, and the safety of the operator during handling. Further, an arrow indicating the traffic direction and a display unit 9 showing a shadow thereof are printed and displayed in the substantially central portion of the reflective sheet 1a.

As shown in FIGS. 2 and 3, slide walls 2a-1 and 2b-1 having an arcuate cross section partially overlap the joint member 2, and _a rotation fulcrum 2c is provided at the center of the arc (axis center O1). It consists of a pair of joint pieces 2a, 2b having skirt portions 2a-2, 2b-2 extending downward from the outer end 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.

At the center of the joint member 2, a handle 13 having a hook 12 provided in the panel 1 and formed in a bent shape like a front view gate is vertically slidable and vertically without hindering the opening and closing rotation of the joint member 2. It has been inserted. 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 peripheral end surface and the end surface.

A hanging portion (string) 17 of a weight 16 made of sandbags or the like is hung from the hook 12, and the weight 16 is placed on a rack 7 as described later to sufficiently extend the rack 7 and along the ground surface. The display panel is placed close to or grounded to enhance the fixing force and stability of the display panel with respect to the ground surface.

As shown in FIGS. 1 and 2, a protective member 18 made of an elongated elastic member in the left-right direction is attached to the upper and lower ends of the exposed surface of the panel 1 with a channel-shaped cross section opened toward the surface side as shown in FIGS. 1 and 2. In this example, the panel 1 is fixedly attached to both upper and lower ends by fasteners 19 such as screws or rivets. Further, a mounting plate 21 made of a band-shaped metal plate is housed inside the channel-shaped cross section of the protective member 18, and the protective member 18 is mounted and fixed to the upper and lower ends of the panel 1 via the mounting plate 21 by fasteners 19. There is.

The rack 7 is assembled by connecting the front and rear frames 7a and 7b, in which aluminum pipe materials having a quadrangular cross section are assembled in a grid pattern, at the center of the front and rear at the rotation fulcrum (axis center O ₂ ) of the connecting shaft 15 so as to be foldable and rotatable. It is configured together. On the other hand, the front and rear ends of the rack 7 have front and rear panels via the rotation fulcrum (axis center O ₃ ) of the connecting shaft 20 housed in the bearing member 22 having a channel-shaped lower end and an L-shaped cross section as a whole. A shaft support is rotatably connected between the inner surfaces of the lower ends of 1.

In this example, as shown in FIG. 4, the bearing member 22 and the connecting shaft 20 housed in the channel-shaped cross section at the lower end thereof are attached by fasteners 6 in the left-right direction along the inner surface of the leg 4 at the lower end of the panel. The head (bolt head) of the fastener 6 maintains the accommodation posture in the bearing member 22.

By this mechanism, the rack 7 is in an open leg state by rotating the panel 1 in the direction of arrow a around the axis O ₁ and the frames 7a and 7b around the axis O ₃ in the direction of arrow b. It is possible to fold it in a closed state, and it is possible to open the legs by reverse operation. Then, in the open leg state of the panel 1, as shown in FIGS. 1 and 2, the stopper mechanism 7c described later overlaps the lattices (frame materials) that intersect vertically and horizontally on the connecting end side of the frame bodies 7a and 7b of the rack 7. It is fixed in a flat plate-like extension posture without rotating downward, and is grounded or stopped close to the ground surface.

When the weight 16 is placed in this extended state, the weight of the weight 16 firmly and stably holds the extended posture of the rack 7, that is, the open posture of the isosceles right triangle in the side view of the display panel, and strong wind pressure and other equipment. It is possible to maintain a stationary posture on the ground surface without falling or moving even when it comes into contact with.

As for the display panel, when the front and rear panels 1 and the rack 7 are folded, the front and rear panels 1 are kept substantially parallel in a state where the lower ends of the frame bodies 7a and 7b are in contact with each other and overlap each other as shown in FIG. The thickness of the frame bodies 7a and 7b is designed so as to be used. Further, when a plurality of display panels are stacked in this folded state, the open end of the channel-shaped cross section of the protective member 18 on the overlapping surface is within the channel of the protective member 18 of the other display panel as shown in the figure. They are stacked in a state where they are in contact with the mounting plate 21 and the channels are in mesh with each other.

Therefore, the surface of the panel 1 of each display panel is prevented from coming into contact with the surface of other display panels or uneven portions even in the stacked state, and the printed display on the surface of the panel 1 is damaged or worn by these contacts. There is no such thing. In particular, when an expensive reflective sheet 1a such as a high-intensity reflective sheet is used for the display surface of the panel 1 as in the illustrated embodiment, the reflective function of the panel 1 itself is provided by protecting the display unit 9 and the reflective heat 1a. The life of the product can be maintained for a long period of time, and the economic effect is great.

Further, since the protective member 18 itself protrudes from the surface of the panel 1 over the entire width, contact with at least other members straddling both protective members 18 is prevented, and the elastic protective member as described above is prevented. By stacking the 18s in a meshed state with each other, the external force applied to the panel 1 at the time of stacking is elastically dispersed and has excellent impact resistance, and the load collapse due to skidding and skidding between the display panels is prevented. There are advantages that can be done.

Next, the rack folding mechanism of the present invention will be described. The connecting shaft 15 of the rotation fulcrum _O2 that connects the left and right frame bodies 7a and 7b of the rack 7 at an intermediate position is on the outer side of the frame body 7a in the front-rear direction. One end of the rod-shaped attachment 24 along the vertical frame member 23a is pivotally supported so as to be rotatable (swing). On the other hand, as shown in FIGS. 1, 2, and 4, the front and rear frame bodies 7a and 7b extend horizontally in the open leg state of the panel 1 and the horizontal frame member 23c on the inner end of the left frame body 7a. Consists of a stopper mechanism 7c that stops in a flat plate state in contact with the upper surface of the right frame body 7b. Due to this flat plate-shaped stationary state, the rack 7 is opened to the maximum width and locked.

In the illustrated example, the attachment 24 is an aluminum square lumber having the same cross section as the frame material of the rack 7, and its tip (swinging end) is adjacent to the connecting shaft 15 and fixed to the upper surface side. It is formed to have a length that abuts on the lower surface of the lumber and stops. Therefore, when the panel 1 is in contact with the ground in the open leg posture, the attachment 24 is in contact with the ground surface GL and is housed in the rack 7 in a horizontal posture along the vertical frame member 23a.

On the other hand, when the panel 1 is lifted by the operator beyond the length of the attachment 24 by the handle 13, the attachment 24 rotates in the counterclockwise arrow c direction due to its own weight, and is substantially vertical to the position of the virtual line shown in the figure. It hangs downward in the direction. Here, a plate-shaped stopper 26 is provided on the vertical frame member 23a so that the attachment 24 does not rotate more than in the vertical direction, and when the attachment 24 rotates downward in the vertical direction, the back surface of the base end thereof is. It is a mechanism that abuts on one side of the stopper 26 and is restricted from rotating.

To close and fold the panel 1 from the above state, lower the lifted panel 1 downward (in the direction of arrow a) and lower it to the protruding height H of the attachment 24 (see FIG. 4), and the attachment 24 is grounded. The connecting axis O ₂ of the frame bodies 7a and 7b abuts on the surface GL and moves upward in the direction of the arrow b, the rack 7 is folded in the chevron direction with this movement, and the frame bodies 7a and 7b are also interlocked with this. Then, it folds and moves in the direction of the arrow a', and finally, due to the weight of the front and rear panels, it rotates until they overlap each other as shown in FIG. 3, and the folding is completed.

In the folded state, the pair of panels are overlapped with each other in substantially parallel to form an integrated panel, so that it is easy to carry and move by the handle. In this folded state, the attachment 24 is raised and accommodated between the front and rear panels in conjunction with the folding of the rack 7.

In addition, in order to open the folded panel 1, it is necessary to manually push open the front and rear panels 1, 1, but when arranging the panel 1 on the ground surface GL, the attachment 24 hangs down, so the panel 1 is moved back and forth. By grounding the tip of the attachment 24 while moving it horizontally in the direction (forward in this example), the attachment 24 is tilted horizontally together with the grounding of the panel 1, and the panel is folded by the operation of the attachment 24 at the time of placement. There is no.
