Description

  The present invention relates to a display device in which a display such as an advertisement, a guide, or a signboard can be moved and can be safely installed at a place of use.

  Conventionally, in order to enable a display such as an advertisement / guidance / signboard to move along a floor surface (ground), a caster is provided on the lower surface of the display device (Patent Documents 1 to 3). When the movement is completed from a movable state that can be freely moved using a caster to a predetermined position and the display device is used at that position (holding state), it has been necessary to hold the display device so as not to move.

  In the holding state, rotation of the caster was stopped using a lock mechanism of the caster (Patent Document 1). Alternatively, an adjuster that moves up and down is provided. In the moving state, the adjuster is shortened and the caster is used. In the holding state, the adjuster is protruded downward from the caster, and the adjuster is grounded to float the caster ( Patent Documents 2 and 3).

JP2000-32016 JP2000-174086 Utility registration No. 3103390

  In the case of the prior art, when using a lock mechanism of casters, it is necessary to lock all the four-wheel casters in order to use them safely in the holding state. There was a problem that it was difficult to confirm. Furthermore, in this case, adjustment was not possible when the floor (ground) was inclined.

  Further, when an adjuster is used, the display device is usually heavy (about 10 to 70 kg), and there is a problem that it is not easy to extend the adjuster against this weight. Further, in this case, when the floor (ground) is inclined, it can be dealt with by adjusting the length of the adjuster. However, at least two adjusters are lengthened against the weight of the display device. Work was required and the work was even more difficult.

  Therefore, in the present invention, since the display main body having the casters and the ground substrate are used, the above-mentioned problems are solved.

That is, the present invention forms a display body by forming a display unit on the upper surface of a moving substrate having casters on the lower surface, and includes the display main body and a grounding substrate that receives the lower surface of the moving substrate, and is configured as follows. This is a display device.
(1) A rail on which a caster of the movable board is placed is provided on the upper surface of the ground board.
(2) The display device can take two states, a “wearing state” in which the moving substrate overlaps the upper surface of the ground substrate and a “detached state” in which the moving substrate is separated from the ground substrate.
(3) The rail has a structure capable of guiding the caster so that the movable board can move between the detached state and the worn state.
(4) The moving substrate and / or the moving substrate is provided with holding means for restricting the movement of the moving substrate from the wearing state.

  In the above, the ground substrate is a display device in which an inclination angle is adjustable with respect to a horizontal direction.

Further, in the above, the display device is configured as follows.
(1) Provide either one or both of the first holding means and the second holding means.
(2) A locking projection is provided on the lower surface of the moving board, and a locking receiver is provided on the upper surface of the grounding board to lock the moving board and restrict the rising of the moving board, and the first holding Means.
(3) Provide pin holes that overlap the moving board and the grounding board in a worn state, and attach pins that restrict horizontal movement by being inserted into both pin holes.
(4) The rail regulates movement of the moving substrate in a direction perpendicular to the length direction when it is in a worn state.

  Furthermore, in the above, the display device is characterized in that a cover that covers at least one edge of the moving substrate is attached to the ground substrate in a wearing state.

Further, the “holding means” in the above may be anything that can maintain the “wearing state”. For example, the movement of the moving substrate in the direction perpendicular to the rail and in the downward direction is normally restricted by the rail. Therefore, under normal safety conditions, the “holding means” may be any means that restricts movement in the rail direction. For example, a locking hole and a locking pin, a locking tool that locks each other, and a recess that accommodates a caster can be formed in the rail.
Further, in a place where there is a lot of vibration, a means for restricting the movement of the moving substrate upward can also be provided.

  Since the present invention is composed of a display body having a caster and a grounding substrate, the display body can be easily held by placing the caster on the rail of the grounding substrate at an arbitrary position.

Therefore, the grounding board can be arranged and adjusted according to the installation location, such as the slope of the ground, walls, road conditions, display direction, etc., so the display device can be moved from the storage location and placed at a predetermined position Work can be made more efficient.

(2) Configuration of ground substrate 30 (FIG. 3)

  Longitudinal reinforcing members 35, 35 made of square pipes are fixed along the long side edges 31 c, 31 d on the upper surface 32 of the rectangular flat plate 31. A central convex portion 38 is formed by bending the upper surface 32 of the rectangular flat plate 31 parallel to the long side edges 31c and 31d and projecting upward at a predetermined distance from the longitudinal reinforcing member 35 at the center side. An intermediate upper surface 38a between the bending margins of the central convex portion 38 is formed flat.

  A lateral reinforcing member 36 made of a square pipe is fixed to one edge 31a of the short edges 31a and 31b of the flat plate 31 along the edge 31a (bent into the convex shape of the central convex portion 38).

  The ground substrate 30 is configured as described above (FIGS. 1A and 2).

(3) Configuration of display device 50 (FIG. 6)

  The display main body 1 and the grounding substrate 30 configured as described above constitute the display device 50 of the present invention (FIGS. 6 and 4).

2. Use of display device 50

(1) First, in the place where the display device 50 is used, the grounding board 30 is disposed by holding only the grounding board 30 from the storage place (usually in the store). At this time, since the ground substrate 30 is light without the display main body 1, it is easy to hold since there is an opening for the hand and can be easily carried to the ground position.
The grounding substrate 30 adjusts the adjusters 37 and 37 so that the flat plate 31 (the upper surface 38a of the central convex portion 38) becomes substantially horizontal in accordance with the inclination of the ground 52. At this time, the display side of the display unit of the display main body is adjusted so that the vertical reinforcing members 35 and 35 of the ground substrate 30 face each other (any vertical reinforcing member 35 may be used).

(2) Subsequently, the display body 1 is moved from the storage place to a place where it is used, and the short side edge 31a of the flat plate 31 of the ground substrate 30 (the display body 1 on the side where the lateral reinforcing material 36 is not provided). With the edges 3a of the flat plate facing each other (FIG. 1 (a)), the casters 6 and 6 of the display main body 1 are placed on the rails 40 and 40 of the ground substrate 30 from the opening 40a of the rail 40, The display body 1 is moved along the caster 6. At this time, since the caster 6 is on the rail 40 (between the side surface of the longitudinal reinforcing member 35 and the side surface 39 of the central convex portion 31), the length direction of the rail 40 Movement (direction perpendicular to the rail 40) is restricted (FIG. 1B).
At this time, the caster 6 is moved from the ground 52 to the rails 40 and 40 of the grounding substrate 30 while the ground 52 is moved by using the casters 6 and 6 of the moving substrate 20 and is moved by the casters 6 and 6 as it is. The open portion 40a of the rail 40 is configured so that it can be easily ridden.

(3) With the casters 6 and 6 on the edge 3a side of the moving substrate 20 of the display main body 1 reaching the end points 40b and 40b of the rails 40 and 40, the casters 6 and 6 are placed against the lateral reinforcement 36, Further progress is restricted (FIG. 1 (c). In this state, the casters 6 and 6 on the edge 3b side of the moving substrate 20 of the display main body 1 are also on the rails 40 and 40. At this time, the vertical piece 16a and the horizontal piece 16 of the locking projection 15 of the moving substrate 20 of the display body 1 respectively enter the slit 48 and the hollow portion 49 of the locking receiver 47 of the ground substrate 30 (FIG. 1C). The upward movement of the movable substrate 20 is restricted, and the assembly of the display device 50 is completed in this state, and the connection hole 42 of the ground substrate 30 and the connection hole 14 of the movable substrate 20 are further communicated. Because The fixing pins 45 are inserted into the connection holes 14 and 42 to restrict the movement of the rail 40 of the display main body 1 in the length direction (FIGS. 6A and 6B). Therefore, the locking projections 15 and the locking receivers 47 are automatically locked without any confirmation work.

(4) Although the flat plate edge 3a of the display body 1 is opposed to the short edge 31a of the flat plate 31 of the ground substrate 30, the rail 40, the flat plate edge 3b of the display main body 1 is opposed. It is also possible to place casters 6 and 6 on 40 (not shown). Even in this case, the engagement between the engagement protrusion 15 and the engagement receiver 47 and the connection of the connection holes 14 and 42 can be performed without any trouble.

3. Other embodiments

(1) In the above embodiment, the fixing pin 45 with the chain 46 is attached to the ground substrate 30, but it can also be attached to the moving substrate 20. Even in this case, in consideration of workability, it is desirable to attach the periphery of the connecting hole 14 (not shown). Further, if the fixing pin 45 is prepared separately, it can be omitted from the ground substrate 30 and the movable substrate 20 (not shown).

(2) Moreover, in the said embodiment, the cover 54, 55 which covers the upper surface of the movement board | substrate 20 can also be provided in a wearing state (FIG. 7). The covers 54 and 55 improve the appearance, conceal the reinforcing members 7 and 8, and flatten the upper surface of the moving board 20, so that it is safe even if a passerby gets on the moving board 20. Further, a pattern can be drawn on the surfaces of the covers 54 and 55, or various displays can be performed (not shown).
In this case, the cover 54 is attached in advance to one side of the grounding substrate 30 (the short side edge 3a side of the flat plate 3) and the cover 55 is attached to the other side (the long side edge 3b side of the flat plate 3). (FIGS. 7A and 7B), a gap 56 through which the support columns 22 and 22 can pass is formed between the covers 54 and 55, and one side 54a of the cover 54 and one side 55a of the cover 55 are formed. An introduction port for placing the movable substrate 20 is formed.
Alternatively, the covers 54 and 55 can be attached (not shown) after the moving substrate 20 is placed on the ground substrate 30 to be in a wearing state.

(3) Further, in the above embodiment, since the locking projection 15 and the locking receiver 47 are provided, the movement of the moving substrate 20 (display main body 1) in the ascending direction with respect to the ground substrate is restricted, and the display Although it is preferable because the main body 1 can be prevented from tilting, the locking protrusion 15 and the locking receiver 47 can be omitted (not shown).

(4) Moreover, in the said embodiment, if the structure of the display part 27, such as a structure, a shape, a magnitude | size, can be attached to the display part receptacle 10 of the movement board | substrate 20, it is arbitrary. Furthermore, the configuration of the display unit receiver 10 may be arbitrarily changed in accordance with the display body 1 (not shown) as long as the display body 1 can be attached.

(5) Moreover, in the said embodiment, although the flat plates 3 and 31 were made into the rectangle, shapes, such as a square, a trapezoid, a triangle, and a circle, are arbitrary (not shown). Moreover, if the casters 6 and 6 of the moving board | substrate 20 get on the rails 40 and 40 formed in the grounding board 30, the flat plate 3 and the flat plate 31 can also be made into a different shape (not shown).
