Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a display device, and particularly to a display device configured by removably attaching a display member to a base member.

(Prior art) Recently, in entrance halls of buildings, etc.
For example, a display device is attached to display tenants.

Such a display device is required to be capable of changing the display every time the tenant changes. Moreover, it must not spoil the atmosphere of the place where the display device is installed, such as the entrance hall.

FIG. 5 is a cross-sectional view showing an example of such a display device, in which the base member 11 has a groove 11a in the center on the display side, and one of the two side plates sandwiching the groove 11a. An undercut portion 11c is formed on the outer surface of the side plate, and a magnet 11d is fixed to a portion of the groove 11a near the other side plate with double-sided tape. The display member 12 has a dovetail groove part 12a in the center on the back side, and an iron plate 12b is fixed with double-sided tape to a predetermined position of the dovetail groove so as to directly face the magnet 11d.
Therefore, the opening edge of the display member 12 on the side away from the iron plate 12b is pushed toward the rear of the undercut portion 11c of the base member 111, and the dovetail groove portion 1
2a is slid along the undercut portion 11c, the other side of the display member 12 is forcibly pushed in, and the display member 12 can be fixed by the adsorption force between the iron plate 11b and the magnet 11d. .

However, with such a configuration, the magnet 11d and the iron plate 12b must be fixed with double-sided tape, which requires many manufacturing steps, which increases the overall cost, and the double-sided tape tends to deteriorate and has a short lifespan. There is a problem.

Furthermore, when removing the display member 12, it is necessary to put your finger on the back side of the display member 12 and pull it forward, but display devices generally have a relatively small gap in the vertical direction. Since the display members 12 are arranged adjacent to each other, it is very difficult to insert a finger into the gap and pull out the display member 12, which makes it difficult to remove it.

FIG. 6 is a cross-sectional view showing a display device with another configuration, in which a groove 21a is formed in the center of the front surface of the base member 21.
The display member 22 has flanges 21b and 21c extending in opposite directions with the groove 21a in between. An inward wide flange 22a and a narrow flange 22b are integrally formed, and between the wide flange 22a and the front plate,
A V-shaped spring 22c is fixed parallel to the wide flange 22a. Therefore, the wide flange 22a is connected to one flange 21 of the base member 21.
Slide the display member 22 against the spring 22c while it is positioned on the back side of the narrow flange 2
If the spring 22b is pushed in so that it is located on the back side of the other flange 21c of the base member 21, the spring 22c
The display member 22 can be attached to the base member 21 due to its elasticity.

However, with such a configuration, the display member 2
2, one side 22 of the display member 22 is removed.
You must put your finger on d, slide it against the spring 22c, and pull it forward. Therefore, considering that the display devices are arranged adjacent to each other with a relatively small gap in the vertical direction as described above, this display device also has a disadvantage that it becomes difficult to remove the display member 22.

Therefore, attachment/detachment is performed only by operating from the front side of the display member without placing fingers on the top or bottom of the display member, and therefore, the display device is arranged without having a gap in the vertical direction into which the fingertip can be inserted. However, there is a need for a display device that can be easily attached and detached.

However, even with display devices that can satisfy these conditions, for example, even if an operation error occurs when removing the display member, it is possible to reliably prevent the display member from falling to the floor, and in the unlikely event that characters are placed upside down. Even if a display member or figure is displayed, it is possible to attach it to the base member in the normal display posture, and in the attached state, at least from the front, only the display member is visible and the other members are not visible. It is necessary to take into account the possibility of improving the appearance by

The present invention was developed in view of these circumstances.The display member is securely fixed and can be easily attached and detached by operating from the front, especially if there is an operational error when removing the display member. , the inconvenience of damage to the display member caused by falling to the floor is avoided, and only the display member is visible from the surface, improving the appearance, and the display member can be mounted in either the upper or lower direction. The purpose is to provide equipment.

(Structure) In order to achieve the above object, the present invention includes a base member attached to the mounting surface A and this base member 1.
The base member 1 is attached to the mounting surface A side and has a channel-shaped cross section with the display member 2 side open. A locking piece 1c with one engaging part 1f is formed on the back surface, and a locking piece 1e extending downward and wider than the locking piece 1c is formed on the front end of the lower wall 1d, and the upper and lower sides are connected to each other. Grooves 1 are formed in the opposing surfaces of the side walls 1b and 1d, respectively.
The display member 2 is formed uniformly in a cross-sectional shape forming 1h and 1h, and the display member 2 is disposed on the rear end portions of the upper and lower side walls 2b and 2c of the main body portion 2a having a channel-shaped cross section and covering the base member in directions facing each other. Forming locking pieces 2d and 2e extending the same length and having the other engaging part 2f that engages with the one engaging part 1f formed on the inner surface,
The facing distance between these locking pieces 2d and 2e is set to be shorter than the vertical dimension of the base member 1, and the wall thickness of the upper and lower locking pieces 2d and 2e is set to be smaller than the vertical dimension of the base member 1.
The dimensions are set such that the locking pieces 1c, 1e can be inserted into the space t between the locking pieces 1c, 1e and the mounting surface 1A when the locking pieces 1c, 2f are not engaged. The opposing distance t between the piece 1e and the mounting surface A is set in such a relationship that the three pieces A, 1e, 2d, and 2e interfere with each other by restricting the rotation of one of the locking pieces 2d and 2e inserted in the distance t. Longitudinal movement prevention members 3, 3 of the display member 2 are press-fitted into both ends of the display member 2 in the longitudinal direction, and have both end surfaces flush with the end faces of the display member. The two legs 4b, 4b are bent and connected to the portal main body 4a and both open ends of the portal main body 4a.
The spring 4 having a structure causes the gate-shaped main body part 4a to protrude in front of the base member 1 in a natural state, and is biased in the leg opening direction to fit the leg parts 4b, 4b into the grooves 1g, 1h, and attach the base member 1 to the base member 1. It is installed.

(Function) According to the present invention, the lower locking piece 2e of the display member 2
Insert it slightly between the wide locking piece 1e of the base member 1 and the mounting surface A, and move it upward to remove the locking piece 2e.
When the display member 2 is pushed into the back of the wide locking piece 1e and then the display member 2 is moved down and released, the spring force of the gate-shaped main body portion 4a of the spring 4 biases the base member 1 forward. The connecting portion 1f and the engaging portion 2f of the display member 2 engage with each other, and the locking pieces 1c and 2d and the locking pieces 1e and 2e engage with each other, so that the display member 2 is fixed to the base member 1.

To remove the display member 2, use your fingertip to press the surface of the display member 2 toward the back side, that is, the mounting surface A side, to release the engagement between the engaging portions 1f and 2f, and then use the finger pressure friction force to display the display member. After moving the member 2 upward and disengaging the upper locking piece 2d of the display member 2 and the upper locking piece 1c of the base member 1, the pressing force is released. As a result, the display member 2 is tilted forward by the spring force of the spring 4, and in this state, the lower locking piece 2e, the mounting surface A, and the wide locking piece 1e of the base member 1 are engaged. are held by interfering with each other. Therefore, this is done by pinching the upper end of the display member 2 with your fingers and pushing it down to release the lower locking piece 2e from between the lower locking piece 1e of the base member 1 and the mounting surface A. Can be done.

Even if your fingertip slips and leaves the surface of the display member 2 in the process of moving the display member 2 upward, as described above, the lower locking piece 2e, the mounting surface A, and the wide The three locking pieces 1e interfere with each other, and the rotation of the lower locking piece 1e within the distance t from the wide locking piece 1e on the mounting surface A is restricted. In other words, the display member 2 as a whole is prevented from falling forward. Furthermore, since the forward tilted state is maintained by the spring force of the spring 4, the display member 2 is prevented from falling off, and the upper end of the display member 2 can be easily pinched with the fingertips.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 is a perspective view showing an attached state and a disassembled state according to an embodiment of the present invention. In the figure, a display device is attached to a base member 1 attached to a mounting surface A.
and a display member 2 attached to the front side of the base member 1, which are manufactured by extrusion molding of non-rusting metal such as aluminum alloy or stainless steel.

The base member 1 is attached to the front end of the upper wall portion 1b of the main body portion 1a, which is attached to the mounting surface A side and has a channel-shaped cross section with the display member 2 side open. A locking piece 1c is formed with a protruding stopper piece 1f, and a protrusion 1i is formed at the front end of the lower wall 1d, extending downward from the lower wall 1d and having a wider width than the locking piece 1c. Locking piece 1
e, and is uniformly formed in a cross-sectional shape with grooves 1g and 1h formed in the opposing surfaces of the upper and lower side walls 1b and 1d, respectively.

The display member 2 extends at the rear end portions of upper and lower side wall portions 2b and 2c of a main body portion 2a having a channel-shaped cross section and covers the base member, and has the same length in opposite directions, and has the one engaging portion 1f on the inner surface. The locking piece 2 has the other engaging portion 2f formed by a groove that engages with the locking piece 2.
d and 2e are formed, and the opposing interval between these locking pieces 2d and 2e is set shorter than the vertical dimension of the base member 1, that is, the dimension from the upper end of the locking piece 1c to the lower end of the locking piece 1e. The thickness of the upper and lower locking pieces 2d and 2e is set to such a size that they can be inserted into the distance t between the locking pieces 1c and 1e and the mounting surface 1A when both the engaging parts 1f and 2f are not engaged. Locking piece 2
The vertical extension length of d and 2e and the locking piece 1e
The opposing distance t between the mounting surface A and the mounting surface A is set in a relationship such that the rotation of one of the locking pieces 2d and 2e inserted in the distance t is restricted, and the three members A, 1e, 2d, and 2e interfere with each other. It is formed in a uniform cross-sectional shape.

Numerals 3 and 3 are for preventing the display member 2 from moving in the longitudinal direction, and are press-fitted and attached to both ends of the display member 2 in the longitudinal direction with their end surfaces flush with each other. Of course, it may be press-fitted using an adhesive.

Reference numeral 4 denotes a spring, which has a gate-shaped main body 4a and both legs 4b, 4b connected to both open ends of the portal-shaped main body 4a and bent. Both legs 4b, 4b are moved to the base member 1 by protruding in front of the base member 1 and being biased in the leg opening direction.
The base member 1 is attached to the base member 1 by fitting into the grooves 1g and 1h.

According to the configuration, the lower locking piece 2 of the display member 2
e is the wide locking piece 1e of the base member 1 and the mounting surface A.
Insert the locking piece a little between the locking pieces 2 and move it upward.
If you press e into the back of the wide locking piece 1e and then move the display member 2 down and release your hand, the spring 4
The engaging portion 1f of the base member 1 and the engaging portion 2f of the display member 2 engage with each other, and the locking pieces 1c and 2d are urged forward by the spring force of the gate-shaped main body portion 4a.
The display member 2 is fixed to the base member 1 by engaging the locking pieces 1e and 2e with each other.

To remove the display member 2, use your fingertip to press the surface of the display member 2 toward the back side, that is, the mounting surface A side, to release the engagement between the engaging portions 1f and 2f, and then use the finger pressure friction force to display the display member. After moving the member 2 upward and disengaging the upper locking piece 2d of the display member 2 and the upper locking piece 1c of the base member 1, the pressing force is released. As a result, the display member 2 is tilted forward by the spring force of the spring 4, and in this state, the lower locking piece 2e, the mounting surface A, and the wide locking piece 1e of the base member 1 are engaged with each other. Interfered and held. Therefore, this is done by pinching the upper end of the display member 2 with your fingers and pushing it up to make the lower locking piece 2e escape from between the lower locking piece 1e of the base member 1 and the mounting surface A. Can be done.

Even if your fingertips slip and leave the surface of the display member 2 in the process of moving the display member 2 upward, as described above, the lower locking piece 2e, the mounting surface A, and the wide engagement The three pieces of the locking piece 1e interfere with each other, and the rotation of the lower locking piece 1e within the distance t between the wide locking piece 1e on the mounting surface A, that is, the forward falling of the entire display member 2 is restricted. Since the forward tilted state is maintained by the spring force of the spring 4, the display member 2 is prevented from falling off, and the upper end of the display member 2 can be easily pinched with the fingertips.

Furthermore, since the longitudinal movement prevention members 3, 3 are press-fitted into both ends of the display member 2 in the longitudinal direction, movement of the display member 2 is prevented, and both end surfaces of the longitudinal movement prevention members 3, 3 are prevented from moving. Since they are flush with the end face of the display member, the longitudinal movement prevention members 3, 3 are not visible when the display device is viewed from the front, and therefore the appearance of the display device is improved.

Furthermore, since the display member 2 is vertically symmetrical, the displayed characters or figures can be displayed upside down, and there is no need to replace the characters or figures.

(Effects) As described above, the present invention has a display member that is detachable from a base member having a locking piece and a wide locking piece, and furthermore, the display member is placed in the groove of the base member so that the display member can be moved forward. Since a biasing spring member is attached, attachment/detachment can be performed only by operating from the front side of the display member, and therefore, this type of display device is arranged adjacent to each other in the vertical direction without any gaps. In addition, the display member can be attached and detached with extremely simple and easy operation without falling off, and longitudinal movement prevention members are press-fitted into both longitudinal ends of the display member, making it easy to clean the display member. Furthermore, since both end surfaces of the longitudinal movement preventing member are flush with the end surfaces of the display member, the longitudinal movement preventing member is not visible when the display device is viewed from the front. As a result, the appearance of the display device is improved. Furthermore, since the display member is formed vertically symmetrically, the displayed characters or figures can of course be displayed upside down, and there is no need to replace the characters or figures.
