[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a shoe-wiping mat that is placed at the entrance/exit of an automatic door to remove dirt and dust from shoes, and also serves as a switch for generating an opening signal for the automatic door. In particular, the present invention relates to a shoe-wiping mat with a sound generation function.

[Prior Art] FIG. 8 is a plan view schematically showing the vicinity of an automatic door using a conventional shoe-wiping mat of this type.

In the figure, 18 is an automatic door, which can be opened and closed as shown by the arrows. 19 is indoor, 20 is indoor 1
9 is an indoor shoe-wiping mat provided, and 21 is an outdoor shoe-wiping mat provided outdoors. The indoor shoe-wiping mat 20 and the outdoor shoe-wiping mat 21 are equipped with pressure-sensitive detection means that act as a switch when stepped on by a foot. When stepped on with a foot, the pressure sensitive detection means is turned on, an automatic door driving means (not shown) is activated, and the automatic door 18 is opened for a certain period of time.

This type of shoe-wiping mat has a function of detecting conditions for opening and closing the automatic door 18 in addition to a function of removing mud and dust from shoes.

[Problems to be Solved by the Invention] In stores equipped with automatic doors 18, greetings are made after detecting the opening and closing of the door and confirming the customer's movements.

However, the automatic doors 18 installed at the entrances and exits of stores, etc. are designed to open and close quietly, and if you are not aware that the automatic door 18 is opening or closing, you may be unable to greet customers without greeting them. This could have caused a negative image of the store.

In addition, in stores and the like where automatic doors 18 are installed, a sensor is required to detect the direction of movement of a person in order to control the opening and closing of the door, and the sensor is usually placed at the bottom of a shoe-wiping mat, or It is placed on the top of the door or on the door handle. That is, these sensors need to be placed as inconspicuously as possible and must operate reliably.

SUMMARY OF THE INVENTION An object of the present invention is to provide a shoe-wiping mat with a sound generation function that can supply a door opening signal to an automatic door and notify people near the door by sound.

[Means for solving the problem] The shoe-wiping mat with a sound generation function according to claim 1 has the following features:
A pressure-sensitive detection means for detecting tread force, a control means for driving a sound generation means by an output signal of the pressure-sensitive detection means for detecting tread force, and a sound generation means for generating sound by the output of the control means. The device is housed in a wiping mat, and the control means outputs an automatic door opening signal.

The control means of the shoe cleaning mat with a sound generation function according to claim 2 includes a leading edge delay means for delaying an output signal of the pressure sensitive detection means, an output signal of the leading edge delay means and an output signal of the pressure sensitive detection means. and an audio reproduction means to which the output signal of the logic gate is input.

[Function] According to claim 1, there is provided a pressure-sensitive detection means for detecting the tread force, a control means for driving the sound generation means by an output signal of the pressure-sensitive detection means for detecting the tread force, and a sound generation means for driving the sound generation means by the output of the control means. Since the shoe-wiping mat houses the sound generating means for generating the sound, the shoe-wiping mat can be easily replaced with a conventional shoe-wiping mat to generate sounds such as greetings and melodies.

Further, the output signal of the pressure-sensitive detection means for detecting the tread force is outputted as an automatic door opening signal directly and/or after being subjected to predetermined signal processing.

In claim 2, there is provided a leading edge delay means for delaying an output signal of the pressure sensitive detection means, a logic gate for inputting an output signal of the leading edge delay means and an output signal of the pressure sensitive detection means, and the logic gate. By providing the audio reproducing means into which the output signal of is input, the moving direction of the person can be easily determined.

[Embodiments of the Invention] Examples of the invention will be described below. In the drawings, the same reference numerals and symbols as in the conventional example indicate the same or corresponding components as in the conventional example.

FIG. 1(a) is a plan view showing a shoe cleaning mat with a sound generation function according to an embodiment of the present invention, and FIG.
- It is a sectional view taken along the A line.

In the figure, reference numeral 1 denotes a pressure-sensitive detection means consisting of a pressure-sensitive switch such as a mud switch that is turned on from off by stepping on it with a foot. Reference numeral 2 denotes a control means having a circuit arranged as shown in FIG. . 3 is a power supply that supplies the pressure sensitive detection means 1 and the control means 2;
It is also used as a signal power source for transmitting an output signal to an automatic door opening/closing drive means 17 (not shown). In this embodiment, a lithium battery is used as the power source 3 because it is easy to downsize and the power consumption of the circuit itself is small, but an external commercial power source may also be used. Reference numeral 4 denotes a sound generating means, which is composed of a speaker using an ultrasonic vibrator or the like. Reference numeral 5b denotes a mat base as an outer frame made of synthetic rubber of the shoe-wiping mat with a sound generating function. Reference numeral 5a denotes a flocked mat, in which a pressure-sensitive detection means 1 is inserted into a concave portion at the center of the mat base 5b, and dust from footwear such as shoes placed on the upper surface of the mat is removed. The shoe cleaning mat of this embodiment is composed of the mat base 5b and the flocked mat 5a.

In this embodiment, the control means 2, the power supply 3 and the sound generation means 4 are located inside the mat base 5b below the pressure sensitive detection means 1. The control means 2 and the power source 3 are made up of a container made of synthetic resin, ceramic, metal, etc., and its contents, so that it will not be easily destroyed even if a foot steps on it. These control means 2 and power source 3 can also be sealed together in one container to form a unit. In particular, when the control means 2 and the power source 3 are powered by a battery or when the voice generating means 4 generates a greeting or a melody, the control means 2 and the power source 3 are arranged as a unit in which the control means 2 and the power source 3 are sealed in one container. Therefore, the functions of the shoe-wiping mat with a sound generation function of this embodiment can be changed, and maintenance is facilitated. In this embodiment, connector terminals or lead wires are drawn out to the unit of the control means 2 and the power supply 3, thereby connecting the pressure sensing means 1 and the sound generating means 4 with the wiring and the automatic door 18. The output line can be

The sound generating means 4 is made of an elliptical resonator so that it is not easily destroyed by being stepped on by foot, but it can also be made of a smaller circular cone, a diaphragm, etc. Depending on the location, it is also possible to use regular campus speakers. Further, like the control means 2 and the power supply 3, the sound generating means 4 is preferably surrounded by a container made of synthetic resin, ceramic, metal, wood, etc., and a plurality of small holes are provided only in the surface portion thereof as entrances and exits for vibration. It is preferable to drill a large-diameter vertical through-hole and perform acoustic coupling perpendicular to the vertical through-hole. In this case as well, it is preferable to cover the surface of the diaphragm with a synthetic resin film or the like, or to position the opening below the horizontal to reduce the influence of dust.

Note that a synthetic rubber mat or flocked mat 5a is placed on the top surface of such a shoe-wiping mat with a sound generation function to remove mud and dust from shoes, similar to a regular shoe-wiping mat, but synthetic rubber mats or flocked mats 5a are used. If the flocked mat 5a is too hard, the pressure sensitive detection means 1 may not operate depending on its arrangement, so it is desirable to use a soft synthetic rubber mat or flocked mat 5a.

FIG. 2 is a sectional view showing an example of a pressure-sensitive switch as the pressure-sensitive detection means 1. FIG.

In the figure, 6 is a perforated sponge-like insulating plate 7a.

7b is an aluminum foil, 8 is a rubber coating to reduce the influence of dust, 9a and 9b are terminals, and 10 is a conductor.

To explain the operation of this type of pressure-sensitive detection means 1, when no pressure is applied to the normal pressure-sensitive detection means 1, the aluminum foils 7a and 7b are insulated by a perforated sponge-like insulating plate 6. Therefore, there is no short circuit between the two conductive wires 10. This state is the OFF state of the pressure sensitive detection means 1. Next, when pressure is applied in the vertical direction in the figure, the perforated sponge-like insulating plate 6 between the aluminum foils 7a and 7b is pushed and becomes thinner, and the aluminum foil 7a is pushed through the holes in the perforated sponge-like insulating plate 6. and 7b come into contact. This contact is transmitted to the two conductive wires 10 via the terminals 9a and 9b, and the two conductive wires 10 are short-circuited. This state is the ON state of the pressure sensitive detection means 10.

Note that the pressure-sensitive detection means 1 includes various known proximity switches, contact switches, or sensors in addition to those shown in FIG. 2, and can be used as necessary.

Generates detection output. In response to the human detection output of the signal c1, the audio reproducing means 13 starts operating. This audio reproduction means 1
3 is equipped with a ROM that stores audio information, and the ROM is triggered by the human detection output to reproduce the audio information. Usually, a plurality of types of such audio information are stored in the ROM, and the audio information is switched and reproduced by the reproduction information switching means 14. As specific audio information, "welcome" and "thank you" are used, and melody (music) is also used. Further, if only one type of audio information is stored in the ROM, other audio information can be reproduced by replacing the ROM.

2. The audio information reproduced by the audio reproducing means 13 is amplified by the amplifying means 15 as necessary, and is supplied to the audio generating means 4. The signal supplied to the voice generating means 4 is reset when a predetermined melody or greeting ends, and the voice reproducing means 13 always synthesizes and outputs voice in a predetermined order from the beginning. . The sound generating means 4 generates sounds of greetings such as "Welcome" and "Thank you" so that the person sitting on the shoe-wiping mat can also hear them.

In FIG. 8, which is described as the conventional example, if the indoor shoe-wiping mat 20 and the outdoor shoe-wiping mat 21 are respectively shoe-wiping mats with a sound generation function according to an embodiment of the present invention, a person can wipe their outdoor shoes. When you are on mat 21, the third
By switching the reproduction information switching means 14 shown in the figure, "Welcome" is displayed, and when a person is on the indoor shoe-wiping mat 21, by switching the reproduction information switching means 14 shown in FIG. 3, "Thank you" is displayed. A sound generating means 4 built into each shoe-wiping mat generates a desired greeting sound.

At this time, in this embodiment, the human detection output signal c
1 is supplied to the automatic door opening/closing driving means 17, so that the automatic door 18 can be controlled. That is, the automatic door 18 is opened by the automatic door opening/closing drive means 17 at the same time as the voice generating means 4 generates a greeting voice such as "Welcome" or "Thank you".

Further, by outputting the input signal of the leading edge delay means 11 as it is, it can be used as a detection signal for information on when a plurality of people are passing at the same time. Or, if those processing circuits are provided in the drive circuit on the automatic door 18 side,
The input signal of the leading edge delay means 11 can be used as is.

In the case of carrying out the present invention, the number of piezoelectric vibrators attached to the diaphragm serving as the sound generating means 4 may be one, but in order to increase the sound volume, a plurality of piezoelectric vibrators may be attached.

Furthermore, in the shoe-wiping mat with sound generation function shown in FIG. 3,
Although an incoming direction detection means consisting of a leading edge delay means 11 and antagonists 1 and 12 is used, the output of the pressure sensitive detection means 1 is directly transmitted to the audio reproduction means 13 and automatically without using this incoming direction detection means. The sound is supplied to the door opening/closing driving means 17, and at the same time as the person gets on the shoe-wiping mat, the voice generating means 4 generates greetings such as "Welcome", "Thank you J", etc.
A melody sound may also be generated. However, when the entrance direction detection means is used as in this embodiment, when generating a greeting such as "Welcome" or "Thank you", the content of the greeting, the person's movement, and the automatic door opening/closing drive means 17 It is possible to match the opening of the automatic door with the opening of the automatic door.

Among these, the control means 2 is supplied with a leading edge delay means 11 for delaying the output signal of the pressure sensitive detection means 1, and an output signal of the leading edge delay means 11 and an output signal of the pressure sensitive detection means 1. The sound generating means 4 is provided with an AND gate 12 and a sound reproducing means 4 to which the output signal of the AND gate 12 is input, and the sound generating means 4 generates a greeting or a melody.

In particular, in this embodiment, since the control means 2 and the sound generation means 4 are housed in the shoe-wiping mat together with the pressure-sensitive detection means 1, it is easy to replace the conventional shoe-wiping mat and generate sounds such as greetings. can be generated. Further, the control means 2
The leading edge delay means 11 and the AND gate 12 inputting the output signal of the leading edge delay means 11 and the output signal of the pressure sensitive detection means 1 are used to prevent false greetings from the voice generating means 4 due to mischief or noise. The occurrence of melodies can be prevented.

As described above, the shoe-wiping mat with a sound generation function according to the embodiment of the present invention includes a pressure-sensitive detection means 1, and an output signal of the pressure-sensitive detection means 1 to drive the sound generation means 4, and also transmits the signal to an automatic door. The control means for outputting the 18 release signals and the sound generation means 4 are housed therein. Among these, a leading edge delay means 11 for delaying the output signal of the pressure sensitive detection means 1, an output signal of the leading edge delay means 11, and an output signal of the pressure sensitive detection means 1 are inputted to the control means.

Further, the leading edge delay means 11 of the control means and the AND gate 12 which inputs the output signal of the leading edge delay means 11 and the output signal of the pressure sensitive detection means 1 are used to prevent noise from the sound generating means due to mischief or noise. , false greeting or melody
can be prevented from occurring.

By the way, the pressure-sensitive detection means 1 for detecting the treading force in the above embodiment is arranged at the four central parts of the mat base body 5b;
When the mat base 5b is only a frame, or when the mat base 5b
In the case of a shoe-wiping mat that does not have b, it suffices to place it on the lower part of the synthetic rubber or flocked mat 5a. Alternatively, the synthetic rubber or flocked mat 5a may be divided into a plurality of parts, and a part molded integrally with the mat base 5b may be exposed between the parts.

Further, the control means for driving the sound generating means 4 with the output signal of the pressure-sensitive detection means 1 of the above embodiment and outputting the signal 9 as an opening signal for the automatic door 18 uses the output signal of the pressure-sensitive detection means 1. a leading edge delaying means 11 for delaying; an AND gate 12 inputting the output signal of the leading edge delaying means 11 and the output signal of the pressure sensitive detection means 1;
