Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting an operation box on a wall, and more particularly to a structure for mounting a wall of an operation box such as a card reader which requires concealing the inside of the operation box or waterproofing.

[0002]

2. Description of the Related Art A card reader is used as a security system for managing entry and exit of buildings and rooms. The card reader is generally mounted on the wall near the door for entry and exit, and when a person who wants to enter and exit passes an ID card etc. through the card reader, the owner of the ID card judges whether entry and exit is permitted. , Unlocking the door only when permitted.

[0003] The housing of such a card reader is composed of a front cover constituted by an operation panel, a card reader section and the like, an inner box for attaching the front cover, and the like. The housing of this card reader is
It is fixed by being fixed to a beam of a building or screwed to an outer box embedded in a recess provided in advance in a concrete wall. This conventional wall mounting structure of a card reader will be described with reference to FIGS.

In FIG. 6, an outer box 3 is fixed to a concave portion 2 provided on a wall 1 by bonding or the like, and an inner box 4 is attached to the outer box 3 by screws. A bracket 5 having a screw hole of an oblong hole 6 is slidably attached to the inner box 4 by screwing, and the bracket 5 is provided with brackets 16 and 17 and a cylinder lock 18 to operate a card reader operation panel and a card. A front cover 7 provided with a leader section and the like is attached. This bracket 16 is used for the front cover 7
And the other end is hook-shaped. The cylinder lock 18 is attached to the front cover 7.
, And a bracket 17 is fixed to the end thereof. When the cylinder lock 18 is turned with the front cover 7 closed, the bracket 17 is attached to a position where it can be fitted to the bracket 5.

When the front cover 7 is attached to the bracket 5 by hooking the hook-like portion of the upper bracket 16 on the bracket 5, the front cover 7 is rotatably hung.
Thereafter, by rotating the cylinder lock 18 attached to the lower portion of the front cover 7, the bracket 17 fixed to the tip of the cylinder lock engages with the bracket 5, and the attachment is completed.

In such a card reader, it is necessary to attach the front cover 7 to the wall without any gaps in order to satisfy requirements such as waterproofness and confidentiality, or to satisfy visual requirements for appearance.

However, it is impossible to attach the front cover 7 to the wall without any gap due to the manufacturing error of each component or the flatness of the wall. By adjusting the screw fixing position, the front cover 7 can be attached without any gap in the wall surface.

For this adjustment, first, the bracket 5 is screwed at an appropriate position, and the front cover 7 is attached. At this time, if there is a gap between the front cover 7 and the wall surface, the gap is measured visually or the like, and the front cover 7 is removed. The mounting position of the bracket 5 is readjusted so as to have the dimensions measured earlier, and the front cover 7 is mounted again. This is repeated until there is no gap, so that the front cover 7
Was mounted on the wall without any gaps.

The card reader type 1 shown in FIG. 6 will be described with reference to FIG.

The basic structure is the same as that shown in FIG. 6, except that a sponge-like rubber or silicone buffer member 19 is attached to the outer peripheral surface of the front cover 7 facing the wall surface.
This is to fill a small gap between the front cover 7 and the wall surface that occurs when the front cover 7 is attached.

As shown in FIG. 8, when the position adjustment of the bracket 5 is completed and the front cover 7 is mounted, the gap between the front cover 7 and the wall surface is made waterproof, drip-proof and dustproof. A jointing material (a caulking property) 20 such as a silicon-based material is filled in the front surface of the outer surface where the front cover 7 and the front cover 7 are in contact with each other to perform a caulking treatment (a joint treatment).

Known documents of such technology include, for example, the structure of an IC card reader / writer described in Japanese Patent Application Laid-Open No. 4-365190 and the mounting structure of a sensor described in Japanese Utility Model Application Laid-Open No. 1-1006767.

[0013]

However, in the conventional mounting structure, various problems have caused the limit of mounting accuracy, the lengthening of the mounting operation, the failure of internal equipment due to water intrusion, and the like. These problems are shown below along with specific examples.

The installation position accuracy of the inner box largely depends on the wall surface accuracy on the building side, and is generally about 10 mm. On the other hand, the mounting accuracy of the operation box is 1/10 m when no cushioning member such as packing is provided between the operation box and the wall surface.
m units are required. Even when a cushioning member such as a packing is provided or a caulking process is used to fill the gap, a system of 1 mm or less is required in consideration of the deformation of the cushioning member, the skill of the worker who performs the caulking process, and the properties of the caulking material.

Further, since there are variations in the installation accuracy and manufacturing error of the inner box, the manufacturing error of the operation box, and the dimensional accuracy of the wall, the removal of the operation box and the adjustment of the bracket must be repeated a plurality of times as described above. did not become.

Also, from another aspect, the cushioning member is generally not so thick. In consideration of waterproofing, drip-proofing and dust-proofing, the thicker the film, the lower its reliability is.
The drip-proof function must be sacrificed, and the intrusion of water or the like may lead to the failure of the function of the card reader, and eventually the control device connected thereto.

Further, by performing the coking process as shown in FIG. 8, the functions of waterproofing, drip-proofing and dustproofing can be ensured.
When it is desired to perform movement, position adjustment, and the like, it is necessary to peel off the caulking material and clean it thereafter.

[0018]

In order to solve the above problems, the present invention provides an inflatable tubular cushioning member between an operation box and a wall, expands the cushioning member, and further cures the cushioning member. By doing so, the waterproof, drip-proof, and dust-proof effects can be achieved easily and quickly, and further, attachment and detachment can be performed easily and quickly.

That is, in the operation box wall mounting structure for mounting the operation box on a wall having an opening,
The operation box has a fixing portion fixed to the wall opening, and has a shape including the wall opening and having a surface facing the wall, and is hollow between the surface facing the wall and the wall in the operation box. A cushioning member having a structure is attached, and a gas or a fluid filler is sealed inside the cushioning member.

Specifically, in an operation box wall mounting structure for mounting an operation box on a wall surface having an opening, an inner box fixed in the wall opening and having an opening in the wall direction, A bracket for slidably fixing the operation box and the operation box, wherein the operation box has a surface including the wall surface opening and facing the wall surface, and a surface and a wall surface facing the wall surface in the operation box. A cushioning member having a hollow structure is attached between them, and a gas or fluid filler is sealed inside the cushioning member.

It is desirable that the encapsulant has curability.

Further, it is preferable that a positioning portion for positioning the buffer member is provided on a surface or a wall surface of the operation box facing the wall surface.

[0023]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to FIGS.

The card reader shown in the figure has an outer box 3 fixed to a recess 2 provided in a wall 1 by bonding or the like.
An inner box 4 screwed to the outer box 3, a bracket 5 having an oblong hole 6 slidably screwed to the inner box 4, an operation panel of a card reader screwed to the bracket 5, and The front cover 7 includes an IC card reader 11 having a display unit, a reading unit, a collating unit, and the like, and a decorative cover 10 that is fitted on the front left and right sides of the front cover 7.

A groove 9 is provided on the back surface of the front cover 7 at the outer peripheral portion facing the wall surface, and a buffer member 12 is fitted and fitted to fit into the groove 9. The cross-sectional shape of the cushioning member 12 is a rectangular shape in which four corners are circular arcs corresponding to the grooves 9 of the front cover 7, but may be appropriately changed depending on the shape of the grooves 9 and the like. . The cushioning member 12 is formed of a flexible and easily deformable material such as synthetic rubber, for example, and has a tubular shape with a hollow inside. However, the cushioning member 12 may have elasticity that can expand and contract.

The cushioning member 12 is provided with a filling port 13 for filling the filling material 14 therein.
In addition, by using a material having high fluidity and a hardening property for the filler 14, it is easy to inject into the buffer member 12, and after a predetermined time elapses after the sealing, the filler 14 is cured so that the buffer member 12 is hardened. It becomes strong when in close contact with the groove 9 and the front cover 7.

Next, the mounting operation of the card reader of the present invention will be described.

First, the inner box 4 is screwed to the outer box 3 fixed to the wall 1 in advance. Similarly, the bracket 5 is screwed to the inner box 4. Since the bracket 5 is provided with the screw hole of the oblong hole 6, the position can be adjusted slidably in the direction perpendicular to the wall surface by loosening the screw. The front cover 7 is attached in a later process. At this time, the attachment position of the bracket 5 is adjusted so that the gap between the front cover 7 and the wall surface becomes a gap calculated in advance as a set value. Strict precision is not required for this position adjustment, and coarse position adjustment may be used.

Since the decorative cover 10 is fitted on the surface of the mounting portion 8, the front cover 7 is detached and screwed to the bracket 5.

With the above, the mounting of the card reader by screwing is completed, and thereafter, the filling material 13 having high fluidity and curability is provided in the cushioning member 12 fitted and incorporated in the groove 9.
Inject. As the filling material 13 is injected, the cushioning member 1
2 gradually expands, and the cushioning member 12 is
When reaching the front cover 7, the filler 1
4 is stopped and the sealing port 13 is sealed. However, if the groove 9 and the cushioning member 12 are in close contact with each other on the card reader side, the airtightness of the card reader and the wall surface is maintained, so that the card reader does not always need to be in close contact with the front cover 7. Therefore, when fitting the buffer member 12 into the groove 9, it is not necessary to strictly incorporate the buffer member 12, and the intended purpose can be achieved even if the buffer member 12 slightly floats.

In this case, even if there is a step (see FIG. 5) or irregularities on the wall surface, or if there is a manufacturing error of each box, bracket and front cover, and even if there is an error in mounting them, the wall surface caused by the manufacturing error. The expanded cushioning member 12 fills the gap between them, thereby making it possible to achieve waterproof, drip-proof and dust-proof effects. Since the card reader is firmly attached to the wall 1 by screwing, the card reader does not move from the adjustment position due to the expansion of the cushioning member 12.

If the functions of waterproofing, drip-proofing and dust-proofing are not required, it is not always necessary to provide a gap, and it is sufficient if the gap is filled to such an extent that it does not cause a sense of discomfort visually. The injection pressure of the filler 13 can be adjusted to be low in order to prevent the member 12 from being damaged.

When the filling port 14 of the cushioning member 12 is sealed, the filler 13 has a curability, so that the filler 13 is cured with the lapse of time, so that the wall 13, the groove 9, and the front cover 7 are removed. It becomes strong when in close contact. Thereby, even if the buffer member 12 is damaged by some influence, the filler 13 is not damaged, and the risk of impairing the waterproof, drip-proof and dust-proof effects is extremely low.

After that, the decorative cover 10 removed for screwing is fitted into the front cover 7 so that
The mounting operation is completed.

Next, an operation of removing the card reader at the time of maintenance and inspection or replacement will be described.

First, the decorative cover 10 inserted into the front cover 7 is removed to expose the mounting portion 8. Remove the screw fixing the mounting part 8 and remove the front cover 7
Remove. Then, the buffer member 12 which has been fitted and hardened by the groove 9 is also separated from the wall surface.

When the front cover 7 is removed, the cushioning member 12 attached to the front cover 7 can be pulled out of the groove 9, thereby completing the removal of the cushioning member. After that, the inner box 4 and the bracket 5 screwed to the outer box 3
By removing the joint, the detaching operation can be easily completed without any trace of joint material or the like.

In the above-described embodiment, the front cover 7 is provided with a groove 9 having a shape sandwiching the buffer member 12 on the back surface as a fixing structure of the buffer member 12. However, a groove 15 is provided on the wall surface. The buffer member 12 is fitted and incorporated in 15. Since both of these have substantially the same operation and effect, if the structure is such that the cushioning member 12 is fixed and is closely attached to the wall surface and the front cover 7, the wall surface (or the inner box) and the front cover 12 are formed.
It is also possible to provide a groove in either one or both.

Note that the present invention is not limited to a card reader, but is applicable to any device such as an operation box that is mounted on a wall surface and needs to fill a gap with the wall surface. is there.

[0040]

As described above, according to the present invention, a large gap is provided between the wall surface and the card reader as compared with the irregularities or steps on the wall surface, and a hollow cushioning member is incorporated in this gap. By enclosing the filler inside, it expands and adheres to each other, so that the deformation variable amount of the cushioning part can be increased, and as a result, the positional adjustment of the inner box and the front cover is sufficient with a coarse accuracy of several mm. . This is because even if there is a large gap between the wall and the card reader, even if there is a variation of about 1 mm, it is difficult to visually recognize it. By being able to withstand. This saves time and effort for repeated position adjustment, and allows easy and quick mounting.

In addition, a highly fluid filler is injected and sealed into the inside of a cushioning member made of a material whose surface is flexible and easily deformed, so that even if there are relatively large irregularities or steps on the wall surface, the cushioning member can be cushioned. The surface of the member adapts to the irregularities and steps on the wall,
Even minute gaps can be filled. This eliminates the need for filling small gaps by coking.
Waterproof, drip-proof and dust-proof effects can be obtained easily and quickly.

In addition, during maintenance, inspection and replacement, no joint material such as caulking material is used, so that no trace of the joint material remains on the wall surface or the card reader. Because
When the card reader is removed, the cushioning member also comes off, and the cushioning member can then be removed from the groove of the card reader, so that replacement can be performed easily and quickly.

When the filler is made of a curable material, the adhesive between the wall surface and the card reader is secured and once cured, there is a risk that even if a sharp object comes into contact with the cushioning member, the material may be damaged. And the risk of impairing the waterproof, drip-proof and dust-proof functions between the wall and the card reader can be suppressed.
