Description

Display device {DISPLAY DEVICE}

The present invention relates to a display device which can be freely detached, for example, from a steel vehicle deck of an automobile carrier.

Background Art Conventionally, an automobile carrier specialized in automobile transportation has a double deck vehicle deck in a line, and each deck displays a route, a parking position thereof, and precautions concerning the vehicle which are frequently carried. Many display devices are provided. As one of the display devices, a cone having a cone shape that can be easily removed or installed is used. However, the cone for a vehicle carrier is larger than a normal one in order to increase visibility from a driver's seat or the like of a frequent vehicle. Large ones exceeding 1.5m in height are used.

Since such a large-size car carrier cone is made of a lightweight synthetic resin as usual, a ring-shaped weight member (weight) is attached to the flange portion of the bottom part in order to stably install it after placement. It is mounted so that it does not move or squeeze by pressing the flange part by its weight. However, this ring-shaped weight requires a certain amount of weight, for example, a weight exceeding at least 10 kg in order to stabilize the cone, and therefore requires a great deal of effort for its installation, transportation and removal work. .

Therefore, the present inventors separately create a ring-shaped weight incorporating a magnet, for example, as shown in Patent Document 1 below, attaching the weight to a flange of a cone, and the adsorption force of the magnet embedded in the weight. The present invention proposes a novel display device weight and a display device using the same, by which the weight is pressed on the vehicle deck made of steel so that the cone does not move and the weight of the entire weight can be achieved. In addition, Patent Document 2 below proposes a triangular cone having a magnet attached to a base in advance.

By the way, since the weight for display apparatuses of the said patent document 1, and the display apparatus using the same are separate objects, there exists a trouble that they must be combined every time they are installed. In addition, the ring-shaped weight has to be secured to some extent in order to securely hold a plurality of magnets, so that there is a certain weight and further weight reduction is desired. In addition, by separately configuring the display device and the weight, the overall manufacturing cost is increased.

On the other hand, since the triangular cone of patent document 2 is a structure which affixed the sheet-shaped magnet on the whole bottom face of a base, adjustment of adsorption force (magnetic force) is difficult, and when it installs in the steel vehicle deck as mentioned above, Depending on the installation position and the situation, the adsorption force is low and the stability is insufficient. On the contrary, the adsorption force is too high, which may make it difficult to separate, making it difficult to secure stability or handleability.

Accordingly, the present invention has been made to solve these problems, and an object thereof is to provide a novel display device that is light in weight, low in manufacturing cost, and which can easily adjust magnetic force.

MEANS TO SOLVE THE PROBLEM In order to solve the said subject, 1st invention has the display apparatus main body which has an annular flange which abuts on the surface which has magnetic property, and the some magnet member mounted so that it may be detachably attached to the said flange, and each said flange is a said magnet. A plurality of mounting holes for mounting the members are provided along the circumferential direction thereof, and the magnet member is provided with a permanent magnet in a cap mounted to be freely attached to and detached from the mounting hole.

According to such a structure, since the magnet member is integrally attached to each mounting hole of the flange, the magnet member can be stably attached to the vehicle deck made of magnetic steel to press the flange firmly so that the display body can be stably installed. have. As a result, since the weight for pressing the flange is unnecessary, the weight of the entire display device can be reduced, and the manufacturing cost can be kept low. Moreover, the adsorption force can be easily adjusted simply by increasing or decreasing the number of the magnet members attached to each mounting hole of this flange suitably.

According to a second aspect of the invention, in the first invention, the cap blocks a cylindrical cap body having a lower opening for accommodating the permanent magnet, and an upper opening of the cap body. It is a display device which consists of a larger cover part and provided the protrusion part in the outer peripheral surface of the said cap main body.

According to such a structure, it can attach easily to each mounting hole of a flange only by inserting a cap from the upper side. In addition, since the projections provided on the outer circumferential surface of the cap body are engaged so as to be caught by the lower edge portion of the mounting hole after mounting, the cap does not fall off from each mounting hole arbitrarily.

3rd invention is a display apparatus which has a cavity in the said cap main body in 2nd invention. According to such a structure, even if the cap main body is lengthened (high) or enlarged, weight increase can be suppressed and further weight reduction can be achieved.

A fourth aspect of the invention is a display device according to the second or third invention, wherein a gap is provided between an edge portion of a lower opening portion of the cap body and a permanent magnet accommodated in the cap body. According to this structure, even when the flange portion is placed on the steel vehicle deck, the edge portion of the lower opening of the cap body is in contact with the deck, and the permanent magnet therein can be prevented from directly contacting the vehicle deck. As a result, damage to the permanent magnet due to impact at the time of installation or the like can be prevented in advance.

In a fifth aspect of the invention, in the first to fourth inventions, the permanent magnet is a neodium magnet. In this way, using a neodymium magnet, one of the rare earth magnets, can obtain a strong adsorption force even with a small magnet member due to its strong magnetic force, thereby making it possible to reduce the usage of the magnet member, thereby achieving weight reduction and cost down. have.

6th invention is 1st-5th invention WHEREIN: The said display apparatus main body is a display apparatus characterized by the cone shape or pole shape which makes the said flange bottom. According to such a structure, the optimal display suitable for an installation place, visibility, a use purpose, etc. can be performed.

A seventh invention includes a display device body having an annular flange, and a plurality of magnet members mounted on the flange so as to be freely attached to and detached from the flange. Accordingly, the display device is characterized by having a plurality of housings, forming a housing case in each of the mounting holes, accommodating a permanent magnet in the housing case, and holding the magnet as a cap. According to such a structure, in addition to each effect as mentioned above, not only the fall of the permanent magnet 32 but also the theft etc. can be prevented reliably.

According to the present invention, since the magnet member is integrally attached to each mounting hole of the flange, the magnet member can be stably attached to a magnetic steel deck or the like to firmly press the flange to stably install the display device main body. As a result, since the weight for pressing the flange is unnecessary, the weight of the entire display device can be reduced, and the manufacturing cost can be kept low. In addition, the suction force can be adjusted simply by appropriately increasing or decreasing the number of the magnet members attached to each mounting hole of this flange.

EMBODIMENT OF THE INVENTION Below, embodiment of this invention is described, referring an accompanying drawing. 1 is an overall perspective view showing one embodiment of a display device 100 according to the present invention, FIG. 2 is an enlarged perspective view showing the vicinity of a bottom portion thereof, and FIG. 3 is a perspective view seen from the bottom surface thereof. As described above, the display device 100 is installed and used on a vehicle deck made of steel of an automobile carrier ship. As shown in the drawing, the display device 100 has a ring shape at a lower end of the display device main body 10 having a conical shape. The flange 20 is provided, and the flange 20 is provided with a plurality of magnet members 30, 30... (Six in the present embodiment at sixty intervals from the center).

The inside of the display apparatus main body 10 is comprised from the material of the hollow cylindrical shape and excellent impact resistance, for example, synthetic resins, such as polyethylene, a soft polyethylene, EVA resin, and a soft vinyl chloride. Then, by attaching a reflector 11 or the like to a part of the outer surface, or attaching another display mechanism (not shown) to the apex, for example, the course of the vehicle that is frequently carried in the line, The parking position, instructions to work on are able to be displayed. In addition to the conical shape, the display device main body 10 may be a pole shape (bar shape), a tree shape, or another shape, and the display device body 10 may be selected according to its installation location, visibility, use purpose, or the like.

The flange 20 is provided so as to protrude horizontally (perpendicularly) from the lower end of the display device main body 10 to the outside, and is formed integrally with the display device main body 10 made of the above synthetic resin by press molding or the like. It is. Moreover, this flange 20 is in a single sheet state, and the plate thickness thereof is substantially the same as that of the display apparatus main body 10, and is made of, for example, a thin plate of about 2 to 5 mm.

As shown in Figs. 2 and 3, the magnet members 30 are provided with a plurality of mounting holes 40, 40, ... (six pieces at 60 ° intervals from the center in this embodiment) formed along the circumferential direction of the flange 20. It is mounted so as to be freely attached and detached from the upper side, respectively, and is comprised from the cap 31 which consists of metal, synthetic resin, etc., and the permanent magnet 32, respectively.

As shown in FIG. 4, the cap 31 has a structure in which a cylindrical or disc-shaped permanent magnet 32 is accommodated in a cylindrical cap main body 33 having a lower opening. That is, this cap 31 closes the upper opening part of the cap main body 33 with the flange-shaped cover part 34, and the tapered projection part 35 extended in the axial direction to the outer peripheral surface of the lower opening side is provided. Plural (four in this embodiment at intervals of 90 ° from the center) are provided, and the permanent magnets 32 are housed therein, and the lower surface of the cover portion 34 is adhesively fixed by an adhesive or the like. .

And since the outer diameter of this cap main body 33 is smaller than the diameter of the mounting hole 40, and the outer diameter of the flange-shaped cover part 34 is larger than the diameter of the mounting hole 40, FIG. 5 and FIG. As shown in Fig. 6, the cap body 33 can be inserted into the mounting hole 40 from above the flange 20, and the cover portion 34 functions like a stopper so that the flange around the mounting hole 40 ( 20) It is in contact with the upper surface.

In addition, as shown in the drawing, the tips of the plurality of protrusions 35, 35, 35, 35 provided on the outer peripheral surface of the lower opening side of the cap body 33 protrude outward from the edges of the mounting holes 40. The position of the cap main body 33 after engagement is prevented by engaging with the edge of the mounting hole 40 by positioning so that it may be set. In addition, in the attachment of the magnet member 30 to the attachment hole 40, since this attachment hole 40 and the cap main body 33 are made of synthetic resin, and deform | transforms as it bends to some extent, this magnet is used. The member 30 can be attached in an instant by simply pressing the member 30 from above. On the contrary, it is also possible to detach the magnet member 30 from the mounting hole 40 by pushing up strongly from the lower side thereof.

6, about 1 mm between the edge part 33a of the lower opening part of this cap main body 33, and the permanent magnet 32 accommodated in this cap main body 33. As shown in FIG. Even if the clearance c is formed and the end 33a of the lower opening of the cap main body 33 is in contact with the floor surface (vehicle deck) or the like, the permanent magnet 32 does not directly contact the floor surface. It is not supposed to. In addition, although the cover part 34 which covers the upper opening part of the cap main body 33 may be a flat disk shape, in order to maintain a moderate intensity | strength so that it may not be easily damaged when it is stepped on by designability or the difference of a vehicle, etc., For example, as shown in the figure, it is preferable to have a spherical shape in which the upper surface slightly swells into a dome shape.

Although this permanent magnet 32 is not specifically limited, A well-known alnico magnet, a ferrite magnet, a rare earth magnet, etc. can be used, It is preferable to use a rare earth magnet which has especially strong adsorption force among these. As the rare earth magnets, samarium cobalt magnets composed of samarium and cobalt and neodium magnets composed of neodium and iron are known. .

In the display device 100 according to the present invention having such a configuration, when the flange 20 side is placed at a predetermined position on a steel deck such as an automobile carrier ship, the plurality of magnets mounted on the flange 20 are provided. The members 30, 30... Are strongly adsorbed by the magnetic steel deck by their magnetic force, and the display device main body 10 can be stably provided by pressing the flange 20 firmly. In addition, since the display device main body 10 is held by the magnetic force in this manner, the display device main body 10 can be mounted not only on the bottom surface of the line but also on the wall surface, the ceiling, the pillar, the door, and the like of the steel sheet. In addition, if it is a structure which a magnet adsorb | sucks, it is not only limited to a ship but can also be easily attached not only to other steel structures but also to the roof of a car.

As a result, the weight for pressing the flange 20 as in the conventional example becomes unnecessary, so that the overall display device can be reduced in weight and the manufacturing cost can be kept low. Moreover, the adsorption force can be adjusted simply by changing the number of the magnet members 30 attached to each mounting hole 40 of this flange 20 suitably, or changing the kind of the permanent magnet 32. As shown in FIG. For example, when high stability (adsorption force) is required, as shown in Fig. 2, the magnet member 30 is mounted in all six mounting holes 40, but such high stability (adsorption force) is not required. In this case, if three magnet members 30 are installed in total, additional weight reduction and cost reduction are possible. This is also the same by changing the type (magnetic force) of the permanent magnet 32 to be used.

In addition, this magnet member 30 can be easily attached to each mounting hole 40 of the flange 20 only by inserting the cap 31 from above. In addition, since the projection part 35 provided in the outer peripheral surface of the cap main body 33 engages after it is attached so that it may be caught by the edge part of the lower side of the mounting hole 40, the cap 31 will arbitrarily attach each mounting hole 40 to it. There is no such thing as dropping off.

Moreover, this magnet member 30 has a gap c between the end 33a of the lower opening of the cap main body 33 and the permanent magnet 32 accommodated in the cap main body 33. Therefore, even when the flange 20 portion is mounted violently directly on the steel deck, since the permanent magnet 32 inside the cap body 33 does not directly contact the deck, The damage of the permanent magnet 32 by an impact etc. can be prevented beforehand. In addition, the resin may be coated so as to fill the gap (c).

In addition, although the permanent magnet 32 of the magnet member 30 is mounted in the cap 31 by an adhesive agent etc., as shown in FIG. 7, the permanent magnet 32 of the lower end part 33a of the lower opening part 33a of the cap main body 33 is larger than this. A plurality of projections 33b protruding inward may be provided, and the lower ends of the permanent magnets 32 may be pressed by the projections 33b, 33b. According to such a structure, not only the fall of the magnet member 30 can be prevented, but the magnet member 30 can be mounted in the cap main body 33 simply by pressing in the magnet member 30 tightly.

8-16 show other embodiment of the display apparatus 100 which concerns on this invention. First, in FIG. 8, the reflecting material 11 is affixed not only in the upper part but also in the lower part of the display apparatus main body 10, and it can improve visibility more by doing in this way. In addition, FIG. 9 integrally forms the U-shaped or L-shaped folded portion 21 downwardly along the periphery of the flange 20. In this way, the strength of the flange 20 can be easily improved. Can be.

Next, FIGS. 10-12 have the structure of the magnet member 30 as an internal hollow structure, and further weight reduction is aimed at. That is, as shown to FIG. 10 and FIG. 11, this magnet member 30 has the upper cap main body 33A which the cap main body 33 integrated with the cover part 34, and the lower cap main body 33B. The lower cap main body 33B is connected to and detached from the upper cap main body 33A via the screw parts 36a and 36b.

The permanent magnet 32 is attached to the lower cap body 33B side, and the cavity S is formed together with the lid 34 inside the upper cap body 33A. Therefore, as shown in FIG. 12, when the upper cap main body 33A is attached (screwed) to the lower cap main body 33B, weight increase can be suppressed even if the length (height) of the cap main body 33 is increased. Additional overall weight reduction can be achieved.

Next, FIGS. 13 to 15 form a cylindrical housing case with a bottom under each mounting hole 40, and accommodates the permanent magnet 32 in the housing case 41. This is pressed by the flat cap 42. As shown in FIG. 14, the planar cap 42 has a plurality of tapered projections 42b on the outside of the cap body 42a of the cylindrical cavity having an outer diameter that can be accommodated in the mounting hole 40 (Fig. In Eq., Two totals, one on the opposite side, are formed. As shown in FIG. 15, when the permanent magnet 32 accommodated in the housing case 41 is accommodated in the mounting hole 40 so as to press, the slit 41a formed in the housing case 41 is formed. ), The permanent magnets 32 are held so as to prevent their fall off by engaging with (a total of two, one on the opposite side in the drawing).

According to such a structure, in addition to each effect as mentioned above, not only the fall of the permanent magnet 32 but also the theft etc. can be prevented reliably. In addition to such a configuration, as shown in FIG. 16, a U-shaped or L-shaped folded portion 31 is formed downward along the periphery of the flange 20 or the bottom surface of the flange 20. By providing the rib 22 for reinforcement extending in the circumferential direction and the radial direction, the weight of the flange 20 can be further increased while achieving weight reduction.
