As shown in Figure 1, the non-contact button input device using a hologram according to the present invention includes a hologram transfer sheet 10, a detector 20, a repeater 30, and a case 40.

The hologram transfer paper 10 is attached to the button B and covers the button B.

The hologram transfer sheet 10 is transparent or translucent, and when light is incident on it, it reflects the incident light upward so that the shape (e.g. number, arrow) provided on the button B is realized as a hologram H in the air above. A pattern is provided. Here, the height at which the hologram (H) is implemented in the air can be adjusted depending on the structure of the pattern.

If the shape of the button B is printed on the bottom of the hologram transfer paper 10 and then attached to the button B, the hologram H displayed in the air may be clearer.

Elevators and doors used by the public are generally equipped with a lighting fixture (L) that illuminates the button (B), so there is no need to install a separate lighting fixture (L) to illuminate the hologram transfer sheet (10), but the button Even if there is no lighting fixture (L) to illuminate (B), a separate lighting fixture (L) must be installed.

The sensor 20 detects an object passing through the hologram H implemented in the air through the hologram transfer sheet 10. Here, the object passing through the hologram H will typically be the user's finger.

The sensor 20 is provided next to the button B and at a position extending on the plane of the hologram H implemented in the air.

The detector 20 emits infrared or ultrasonic waves toward the hologram H, and detects the object by receiving the emitted infrared or ultrasonic waves being reflected by an object passing through the hologram H.

The detector 20 can determine the distance from the detector 20 to an object through the time it takes for infrared or ultrasonic waves to be reflected and input after they are emitted. In other words, even if there are multiple buttons (B) in the direction in which the detector 20 emits infrared or ultrasonic waves, it is possible to know which button (B) the object has passed through the hologram (H) corresponding to.

The repeater 30 transmits the detection signal of the detector 20, that is, the detection signal regarding which object has passed through the hologram (H) corresponding to which button (B), by wired or wirelessly to the controller of the button (B). Pass it to C).

Taking an elevator as an example, when an object passes through the point corresponding to the 3rd floor button (B) in the hologram (H), the detector (20) detects this and detects that the 3rd floor button (B) has been pressed, and the repeater (30) ) transmits the detection signal corresponding to the 3rd floor button (B) to the controller (C), and the controller (C) lights up the 3rd floor button (B) to notify the user and drives the motor to move the elevator car to the 3rd floor. I order it.

The sensor 20 and the repeater 30 are built into a case 40, and the case 40 is fastened to the structure 1 provided with a button B.

Fastening portions 41 are provided on both sides of the case 40, and fastening holes 43 are formed in the fastening portions 41. In addition, a fastening hole 43 is formed in the structure 1, and the fastening member 100 penetrates the fastening hole 43 of the case 40 and the structure 1 to attach the case 40 to the structure 1. Fasten it.

The fastening member 100 has a structure that can easily and quickly fasten and separate the case 40 to the structure 1 and prevents erroneous detection by the detector 20 by preventing shaking of the case 40. have

Referring to Figure 2, the fastening member 100 has the following structure and operating mechanism.

The fastening member 100 includes a body 110, a fastening block 120, a first rotating bar 130, a second rotating bar 140, a spring 150, a rotating body 160, and a connecting bar 170. It is made including.

The body 110 is provided with a penetrating part 111 that penetrates the fastening hole 43 of the case 40 and the structure 1, and is provided at one end of the penetrating part 111 to fasten the case 40. It includes a head 112 caught on the part 41. And a hollow part 113 is formed inside the head 112 and the through part 111, and an outlet hole 114 communicating with the hollow part 113 is formed in the through part 111.

The fastening block 120 is provided at the other end of the penetrating part 111, is drawn out from the outlet hole 114, and is hung inside the structure 1.

The first pivoting bar 130 and the second pivoting bar 140 are provided in the hollow portion 113 of the penetrating portion 111, intersect in an X shape, and an axis pin 135 is coupled at the intersection portion. and is brought together. And guide pins 131, 141 are provided to protrude at the ends of the first pivot bar 130 and the second pivot bar 140, and the guide pins 131, 141 are provided inside the penetrating portion 111. A guide groove 115 is formed to guide the seated rotation.

The fastening block 120 is hinged at the outer ends of the first rotating bar 130 and the second rotating bar 140, and a stopper (not shown) is provided to limit the two-way rotation range of the fastening block 120. do.

The spring 150 connects the first pivot bar 130 and the second pivot bar 140 and pulls the first pivot bar 130 and the second pivot bar 140.

The rotating body 160 is rotatably provided in the hollow portion 113 of the penetrating portion 111. A coupling protrusion 161 to which a tool is coupled is protruding from one surface of the rotating body 160. The coupling protrusion 161 has a polygonal pillar structure such as a square pillar or a hexagonal pillar. The rotating body 160 can be rotated by coupling the tool to the engaging protrusion 161 and turning it.

The connecting bar 170 connects the other surface of the rotating body 160 and the inner end of the first rotating bar 130.

The operating mechanism of the fastening member 100 configured as described above is as follows, referring to [A] and [B] of FIG. 2.

When the tool is coupled to the engaging protrusion 161 of the rotating body 160 and rotated to rotate the rotating body 160, the connecting bar 170 pushes the inner end of the first rotating bar 130 to form the first rotating body 160. The rotation bar 130 is rotated counterclockwise.

As shown in [A] in Figure 2, the first rotating bar 130, which rotates counterclockwise, with the outer ends of the first rotating bar 130 and the second rotating bar 140 located at the top, rotates at a certain angle or more. When the spring 150 pulls the first rotating bar 130 and the second rotating bar 140, the first rotating bar 130 moves counterclockwise and the second rotating bar 140 moves clockwise. By automatically rotating, the outer ends of the first pivoting bar 130 and the second pivoting bar 140 are located at the bottom, as shown in [B] of Figure 2.

When the first pivoting bar 130 and the second pivoting bar 140 rotate and the outer end moves from the top to the bottom, the fastening block 120 moves from the top to the bottom of the draw-out hole 114 and then moves through the draw-out hole 114. It contacts the inclined surface 116 formed at the bottom of 114, rotates outward, and is pulled out from the draw-out hole 114. It is blocked by the stopper and can no longer rotate outward, and is pulled out from the draw-out hole 114 to form the structure ( 1) It gets caught inside.

In the state [B] of Figure 2, the spring 150 exerts a force pulling the first pivot bar 130 and the second pivot bar 140, so that the fastening block 120 is inside the structure 1. A pushing force acts to fix the head 112 of the body 110 and the fastening block 120 by pressing the fastening portion 41 of the case 40 and the structure 1 interposed between them. It will be done. The fastening block 120 has elasticity to push and press the structure 1, so it does not come loose even when an impact is applied and prevents the case 40 from shaking. And the case 40 does not shake, thereby preventing the risk of false detection by the sensor 20.

When separating the case 40 from the structure 1, if the rotating body 160 is rotated in the opposite direction, the state is changed from [B] to [A] in Figure 2 by the above operating mechanism, so that it can be easily separated. there is.

When the case 40 is pulled with strong force in the state [B] of Figure 2, the first rotation bar 130 and the second rotation bar 140 rotate together to become the state [A] of Figure 2, and the case (40) can also be separated from structure (1). To prevent this, there is a locking protrusion 117 at the bottom of the hollow portion 113 that is inclined on one side to allow clockwise rotation of the second rotating bar 140 and protrudes vertically on the other side to prevent counterclockwise rotation. is formed Even if the case 40 is pulled, the second rotating bar 140 is caught on the locking protrusion 117 and cannot rotate, thereby preventing the case 40 from being arbitrarily separated from the structure 1.

On the other hand, the first rotating bar 130 is provided with a push protrusion 132 having a triangular cross-section, and while the first rotating bar 130 rotates and passes the second rotating bar 140, the push protrusion 132 ) lifts the second pivoting bar 140 so that the second pivoting bar 140 is released from the locking protrusion 117, and thus the second pivoting bar 140 can rotate.

In other words, only when the user turns the rotating body 160 using a tool can the first rotating bar 130 and the second rotating bar 140 be rotated to separate the case 40 from the structure 1, By forcibly pulling the case 40, the first pivoting bar 130 and the second pivoting bar 140 do not rotate, thereby preventing them from being separated arbitrarily.

In the above description of the present invention, a non-contact button input device using a hologram having a specific shape and structure has been described with reference to the attached drawings. However, the present invention can be modified and changed in various ways by those skilled in the art, and these modifications and changes can be made. It should be interpreted as falling within the protection scope of the present invention.
