Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for displaying posters, guide display objects and the like, and more particularly, the present invention relates to a display device for facilitating the work of exchanging posted objects.

[0002]

2. Description of the Related Art Display devices for displaying posters for advertisements and information items for guidance are installed in the premises of stations, underground passages, and venues. Most of these display devices are integrally fixed to a wall surface of a station yard or a corridor using a wall surface, and an illumination lamp provided inside the display device illuminates a poster from behind to make it easy to see even in a dark place. Most of these display devices are large, especially those that display posters for advertisements,
Also, from the viewpoint of strength, safety, and aesthetics, many products made of metal, more specifically, made of extruded aluminum material have been provided recently.

This type of display device usually has a front display frame that can be freely opened and closed in order to replace a posted object. Generally, the display frame is hinged and opened like a door at the time of replacement. The back of a transparent plate such as a glass plate that is fitted in the frame is opened so that posters and other posters to be put along here can be attached and detached from the outside. This opening of the display frame is also used when replacing the illumination lamp provided inside so that the work can be performed from the front side of the display device.

However, since the hinges of the display frame are generally connected to the main body frame by hinges, in the case of a large-sized display device, the poster also becomes large accordingly, so the display frame is opened. However, on-site replacement work becomes extremely difficult. In particular, work on passages and parts along railway lines inside stations is dangerous because it involves sewing between vehicle passages, and it is more difficult due to time constraints. .

Therefore, as a method for solving these problems, the applicant has previously proposed the inventions described in JP-B-43-6181 and JP-B-57-54123. These two proposals are to detachably attach the display frame to the main frame that is fixed to the wall surface of the structure such as the premises of the station. When replacing the display object, lift the display frame and lower the free edge of the display frame. It is designed so that the display frame can be removed from the main frame by disengaging and releasing it, rotating it to the predetermined position with the hinge point as a fulcrum, then removing the hinge relationship, and safely by moving the place. In addition, the work can be performed in a comfortable posture.

[0006]

The display device with the detachable display frame has an advantage of avoiding the work at the site when the display object is exchanged, but one drawback is that even when the display frame is simply opened. Since the display frame of the heavy object has to be lifted up, the weight of the transparent plate is added to the large-sized apparatus, so that there is a problem that only two or more workers can open and close the work. In particular, since this display device has a structure in which the support shaft of the hinged part and the bearing part can be separated, the display frame tilts with respect to the body frame and is scratched by the inner peripheral surface of the opening when the lifting amount on the left and right is different. The smooth forward pullout was sometimes hindered.

On the other hand, the conventional detachable display device has a hinged portion which can be engaged and disengaged, and an opening / closing mechanism for lifting, a so-called "Kendon" type mechanism. Since the frame material has a different shape in advance, therefore, even when assembling using aluminum extruded mold material, it is necessary to prepare at least two kinds of mold materials having different cross-sectional shapes. Therefore, there is a problem that the manufacturing cost increases.

The present invention has been researched and developed to solve these problems. The hinge means is improved so that the display frame can be freely and easily detached from the body frame. An object of the present invention is to provide a display device for displaying advertisement posters and the like that can be easily opened by pulling out the lower free end in the front direction without lifting the display frame when opening and closing the display frame.

Further, in view of the inconvenience caused by assembling and manufacturing the mold members having different shapes in the related art, the present invention provides a display device which can be assembled by the same mold member to improve the manufacturability and can be provided at a low cost. Is what you are trying to do.

Further, in addition to the improvement of the hinged structure of the display frame, the present invention further includes an inner opening which becomes a second opening inside so as to face the outer opening formed on the front surface of the body frame. When the display frame is removed by forming a middle frame that can be opened and closed in the inner opening, internal parts such as a lighting lamp provided inside the main body frame can be directly seen to make the appearance of the display device installation place beautiful. An object of the present invention is to provide a display device that is not damaged.

[0011]

It is a locking member composed of. The inclined engaging piece 3
9b extends from the center of the front side edge of the substrate, while the pressing piece 3
9c extends in parallel from both ends of the rear side edge so as to sandwich the tip of the engaging piece 39b so that the tips of the engaging pieces 39b cross each other.

The locking member 39 is fixed to the inner surface (upper surface) of the lower frame 5 forming the opening 3 of the main body frame 1 with a board 39a so that the inclined engagement piece 39b faces the front surface. There is. For the display frame and the middle frame which are suspended and supported by swinging around the support shaft 25 as a fulcrum, locking pieces 41 and 42 are attached to the lower surfaces of the lower frame members 16 and 36, respectively. It is restrained by being hooked on the stop member 39. The two locking pieces 41, 42 are restrained by the respective frames 2, 13
When each of the locking pieces is closed, each locking piece pushes down the inclined engaging piece 39b of the locking member, and further, the pressing piece 39c is pushed backward to release the pushing down of the inclined engaging piece 39b to restore the restrained state. The obstruction will be maintained. Since the engaged locking pieces 41 and 42 are sandwiched between the inclined engaging piece 39b and the pressing piece 39c, they are restrained without rattling.

The closed display frame 2 is fitted in the outer opening 3 so that the surface of each frame member is flush with the surface of the piece 8 provided at the front end edge of the main body frame 1 to provide a sense of unity. But
The closed display frame 2 is an inclined locking piece for inserting a releasing tool such as a thin metal plate into the locking frame member 39 through a slight gap 43 formed between the lower frame member 16 and the lower frame 5 of the main frame. 37b
Push down to disengage and release the occlusion.
Incidentally, when the inclined engaging piece 39b is pushed down by the releasing tool to release the engagement, the lower end of the display frame 2 is automatically pushed out of the opening 3 because the pressing piece 39c is biased forward. Will be. For this reason, although the display frame is not provided with a handle portion, the display frame can be pulled out and opened by directly holding the lower end with a hand.

Along with this releasing operation, the middle frame 13 can be released and released in the same manner. Of course, in the illustrated example, it is needless to say that only the display frame 2 can be opened, or the middle frame 13 overlapping the display frame 2 can be opened together.

By the way, the middle frame 1 housed in the inner opening 10
3 is a semi-transparent plate 44 to be fitted so as to disperse the light of the illumination lamp 14 to give uniform light to the display screen 20, and to prevent the inside of the illumination room 14 from being exposed when the display frame 2 is removed. The frame members 36 and 37 made of extruded aluminum are formed into a frame shape in a rectangular shape, and a semitransparent plate is formed between two strips 45 and 45 projecting from the inner circumference of the front portion inside the frame. A milky white acrylic translucent plate 44 is fitted and killed so that when it is put along the display frame 2, the transparent plate 19 is snugly fitted behind the transparent plate 19.

The present invention is configured as described above,
At the time of use, the display frame 2 and the middle frame 13 are closed, and the locking pieces 41 and 42 at the lower edge are hooked on the locking portion 39, and the display object 20 is attached to the rear surface of the transparent plate 19 in the display frame, and the fluorescent lamp is used. The light will come from behind. On the other hand, at the time of exchanging the post, the engagement of the locking portion 39 is released, and the display frame 2 is flipped forward with the support shaft 25 as a fulcrum to replace the post attached to the back surface of the transparent plate 19.

In this case, the display frame 2 may be supported when the replacement work can be carried out easily. However, when the device is large and the weight is heavy, or when it is troublesome to replace the posted matter, the display frame 2 is replaced. When it is flipped up, the shaft locking portion 26 that locks to the support shaft 25 is pushed up to disengage, taken out from the outer opening 3, and the replacement work may be performed at a safe place. It suffices to hang it back.

In this way, the display part 2 can be replaced by opening and closing and removing the display frame 2, while the device of the present invention allows the inside frame 1 to be opened when the display frame is removed from the main frame.
Since it is closed by 3, the exposure of the illumination lamp 14 and the like can be prevented. This middle frame may be closed during the replacement of the bulletin board, but may be opened together with the opening of the display frame, and at this time, the bulletin board 20 is attached to the semitransparent plate 44 of the middle frame 13 and posted. However, the display frame may be removed and then covered.

On the other hand, the middle frame 13 has the support shaft 25 after opening.
Since the shaft locking portion 27 can be taken out from the main body frame by removing it from the main body frame, it can be removed for maintenance and inspection of the interior of the lighting room 11 and repair and replacement of parts.
The inner opening can be closed by re-engaging the shaft locking portion 27 after the work.

Although the embodiment of the present invention has been described above, as is apparent from the above-mentioned construction, the main body frame 1
The display frame 2 housed in the opening 3 is rotatably supported by the support shaft 25 as a fulcrum and can be freely opened and closed, while the shaft locking portion 26 that engages with the support shaft 25 is easily lifted by raising the display frame. If it is difficult to convert the poster 20 such as a poster, the display frame can be removed from the main frame to perform the operation in a safe state. In some cases, the location can be changed. it can.

On the other hand, since the device of the present invention has a structure in which the inside which is opened when the display frame 2 is removed is closed by the middle frame 13, the parts such as the illumination lamp 14 are prevented from being exposed, which is aesthetically preferable. Also, since the inner frame can be freely opened and closed, it can be easily performed when exchanging the parts inside the illumination room as described above, and the support shaft 2 can be used if necessary.
Since the shaft locking portion 27 can be removed from the shaft 5 and taken out, in the case of complicated work, there is an advantage that the work can be performed easily and safely.

Further, the display frame 2 fits into the front surface of each frame portion forming the main body frame 1 when being closed so that the front surface of the frame material having a frame shape is aligned so as to be flush with each other, and protrudes forward at this time. In addition, since the display frame itself fits into the opening of the display frame and is locked to the locking portion in this state, there is an advantage that a safe closed state can be obtained and a beautiful finish can be achieved. In addition, since the frame members of the main body frame and the display frame are made of shape members having the same sectional shape, there is an advantage that they can be provided at low cost.
