Description

[Detailed Description of the Invention] [Industrial Application Field] This invention can be used, for example, to remove mud and dust from shoes by being spread at the entrance and exit of an elevator, and for example, when a trolley is boarding an elevator for human use. The present invention relates to a shoe-wiping mat that outputs a signal such as an audio signal in order to prevent this, and particularly 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 elevator using a conventional shoe-wiping mat of this type.

In the figure, 17 is an elevator for the human world, and 18 is a door of the elevator 17. A shoe-wiping mat 19 is placed outside and in front of the door 18 of the elevator 17, and has the function of removing mud and dust from shoes. Reference numeral 20 denotes a trolley, which moves in the direction of the door 18 of the elevator 17, that is, in the direction of the illustrated arrow. Reference numeral 21 denotes a floor display device provided on a wall portion on the side of the door 18 of the elevator 17.

Now, when the trolley 20 approaches the door 18 of the elevator 17, the person pushing the trolley 20 appears on the floor display device 21.
You will see the display. This elevator is for the human world, so the sign says "For the human world" and "Please refrain from using trolleys." Normally, the person pushing the trolley 20 sees this display and determines that the trolley 20 cannot ride on the elevator 17.

[Problems to be Solved by the Invention] However, the person pushing the trolley 20 may overlook the floor display device 21, and in that case, the person who is pushing the trolley 20 may miss the floor display device 21. I ended up waiting for a while.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a shoe-wiping mat with a sound generation function that can detect a cart with the shoe-wiping mat and alert the user to the cart using an audio signal or the like.

[Means for Solving the Problems] In order to solve the two-part problem, the shoe-wiping mat with a sound generation function of the invention of claim 1 has a plurality of pressure-sensitive detection means arranged sequentially in the traveling direction of the trolley. a sequential operation detection means for detecting that the wheels of the truck sequentially actuate these pressure-sensitive detection means; a recording and reproducing means that is activated by an output signal of the sequential operation detecting means; and a reproduction from the recording and reproducing means. The vehicle is equipped with a sound generating means for generating a sound to warn the trolley by means of a signal.

Further, the shoe-wiping mat with a sound generating function of the invention of claim 2 has a plurality of pressure-sensitive detection means sequentially arranged in the traveling direction of the trolley, and the wheels of the trolley sequentially activate these pressure-sensitive detection means. The apparatus is equipped with a sequential operation detecting means for detecting this, and an output means such as a light and/or sound generating means, an electromagnetic wave generating means, a magnetic field generating means, etc. for outputting the output signal of the sequential operation detecting means to the outside.

[Function] In the invention of claim 1, the fact that the operation detection means sequentially generates the output signal means that the shoe-wiping mat with the sound-generating function is placed close to the elevator for use in the human world, for example. This corresponds to the fact that the trolley, etc. is moving on the wiping mat, so at this time, the recording and reproducing means is activated, and based on the reproduction signal from the recording and reproducing means, the sound generating means generates a sound and the trolley is moved. This is to give you a warning.

Similarly, in the invention of claim 2, when it is detected that the cart or the like is moving on the shoe-wiping mat with the sound generating function, the output of the light and/or sound generating means, the electromagnetic wave generating means, the magnetic field generating means, etc. means can be activated to limit the control of the elevator.

[Embodiments of the Invention] Hereinafter, a shoe-wiping mat with a sound generation function according to an embodiment of the present invention will be described. 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 partially cutaway plan view showing a shoe cleaning mat with a sound generating function according to the first embodiment of the present invention, and FIG. 1(b) is a cross-sectional view taken along the line A--A. It is a diagram.

In the figure, reference numerals 1a to IC are pressure-sensitive detection means consisting of three pressure-sensitive switches provided on the shoe-wiping mat of the elevator 17 for human use, which is turned on by stepping on it with a foot or a wheel of the trolley 20. The pressure sensitive detection means 1a to IC are shown in FIG.
A person gets on the elevator from the bottom of FIG. 1(a), and the trolley 20 is also arranged so as to approach the elevator 17 from the bottom of FIG. 1(a). 2 is a control means as shown in FIG. 3 which will be described later, and 3 is a power supply for supplying the pressure sensitive detection means 1a to IC and the control means 2. 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. 5a is a flocked mat, and pressure-sensitive detection means 1a to 1c are provided at four central parts of the mat base 5b.
This is to remove dust from shoes and other footwear placed on the two sides of the floor. The shoe cleaning mat of this embodiment is composed of the mat base 5b and the flocked mat 5a.

The control means 2, power supply 3, and sound generation means 4 of this embodiment are located inside the mat base 5b below the pressure-sensitive detection means 1a to 1c. 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 person or a cart 20 rides on it. . These control means 2 and power source 3 can also be sealed together in one container to form a unit. In particular, the control means 2 and the power supply 3 may be connected to each other in the case where a battery is used or when the sound generation means 4 generates a warning sound or a message.
The functions of the shoe-wiping mat with sound generation function of this embodiment can be changed in units of units sealed in one container, and maintenance is easy. In this embodiment, the unit of the control means 2 and the power source 3 has a connector or a terminal for a lead wire, so that wiring with the pressure sensitive detection means 1a to 1c and the sound generation means 4 can be carried out.

The sound generating means 4 has an elliptical resonance side that is not easily destroyed even when stepped on by a foot or when the trolley 20 is loaded with luggage, but it may be constructed from a smaller circular cone, a diaphragm, etc. Also, depending on where they are installed, it is also possible to use normal 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 particles.

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, depending on its arrangement, the pressure sensitive detection means 1a to 1c may
Since this may not work, it is desirable to use a soft synthetic rubber mat or flocked mat 5a.

FIG. 2 shows one of the pressure-sensitive detection means 1a to 1c used in the shoe-wiping mat with sound generation function according to the first embodiment of the present invention.
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.

The operation of this type of pressure sensitive detection means 1a to 1c will be explained as follows.
When no pressure is applied to the normal pressure-sensitive detection means 1a to 1c, the aluminum foil 7a and the aluminum foil 7b
Since the space between the conductive wires 10 is insulated by the perforated sponge-like insulating plate 6, no short circuit occurs between the two conductive wires 10. This state is the off state of the pressure sensitive detection means 1a to 1c. Next, when pressure is applied in the vertical direction in the figure, the perforated sponge-like insulating plate 6 between the aluminum foil 7a and the aluminum foil 7b is pushed and becomes thinner, and the aluminum passes through the holes in the perforated sponge-like insulating plate 6. The foil 7a and the aluminum foil 7b are in contact with each other. This contact is at terminal 9a.

9b to the two conductive wires 10, and the two conductive wires 1
0 means that it is shorted. This state is the ON state of the pressure sensitive detection means 1a to 1c.

In addition to the pressure-sensitive detection means 1a to 1c shown in FIG. 2, there are various known proximity switches, contact switches, or sensors that can be used as required.

FIG. 3 is a block diagram showing the electrical circuit of the shoe-wiping mat with a sound generation function according to the first embodiment of the present invention.

FIG. 3 is a block circuit diagram of a shoe-wiping mat with a sound generation function according to the first embodiment of the present invention, in which two trolleys are installed in the Hitoyoshi elevator.
0 approaches, and performs an operation to warn the person pushing the trolley 20 that they cannot ride it.

In the figure, +V is the power supply voltage, 1a to 1c are the pressure sensitive detection means, 11 is the first delay means, 12 is the second delay means, 13 is the AND gate as the logic gate of this embodiment,
14 is a recording/reproducing means, and 4 is the above-mentioned audio generating means.

Next, the operation of the block circuit diagram of the shoe-wiping mat with sound generation function of this embodiment will be explained using the time chart shown in FIG.

When the trolley 20 moves toward the elevator 17 and the shoe-wiping mat is stepped on by the wheels of the trolley 20, the pressure-sensitive detection means 1a is first turned on (at time t1), a signal a appears on the input side of the first delay means 11. . The first delay means 11 includes a trolley 20
predicts the time for the wheel to arrive at the position of the pressure-sensitive detection means 1c, and outputs a signal d with a pulse width of 1, which is a delay pulse between the minimum value and the maximum value of this predicted time and includes time points t2 to t9. do. As the wheel of the truck 20 with the pressure sensitive detection means 1a turned on turns on the pressure sensitive detection means 1b as it moves, a signal appears on the input side of the second delay means 12 (at time t3).

The second delay means 12 predicts the time when the wheels of the trolley 20 will arrive at the position of the pressure-sensitive detection means 1c, and generates delay pulses t5 to tl between the minimum and maximum values of this predicted time.
.

A signal e at the time point is output. The wheels of the truck 20 which have turned on the pressure sensitive detection means 1b then turn on the pressure sensitive detection means IC (at a time te), and a signal C appears. In this way, the truck 20 turns on the pressure-sensitive detection means 1a to 1e in order. The AND gate 13 inputs the signal cSdSe and performs logic to determine whether the truck 20 has turned on the pressure sensitive detection means 1a to IC in order. If the output signal f is generated from the AND gate 13, it means that the cart 20 has turned on the pressure-sensitive detection means 1a to IC in order, and it can be seen that the cart 20 is present on the shoe-wiping mat. .

2 Here, the circuit consisting of the first delay means 11, the second delay means 12, and the AND gate 13 constitutes the sequential operation detection means of this embodiment.

The output signal f from the AND gate 13 is transmitted to the recording/reproducing means 1
4. This recording and reproducing means 14 has a ROM that stores audio, and the ROM starts reproducing the audio in response to a signal f written in -. This voice reproduction information is appropriately amplified and then supplied to the voice generation means 4, which generates voice guidance such as, "This elevator is for married women, so you cannot ride the trolley." Do this.

Further, the sound generating means 4 may generate a buzzer sound based on the signal f. The buzzer sound can also be generated as a playback sound from the ROM built into the recording/reproducing means 14, or the buzzer sound can be followed by a message saying, ``This elevator is for married women, so please do not use the trolley.''yeah"
You can also generate a playback sound. That is, a plurality of types of such audio information are usually stored in the ROM, and the audio information is switched and reproduced by a reproduction information switching means (not shown). Furthermore, if there is only one type of audio information in the ROM, other audio information can be reproduced by replacing the ROM.

The person pushing the trolley 20 will promptly move the empty trolley 20 in front of this elevator 17 in response to the above-mentioned guidance and warning, and make the trolley 20 wait in front of another freight elevator.

In the embodiment shown in FIG. 3, the detection of the trolley 20, etc. was performed based on the outputs from the pressure-sensitive detection means 1a to 1c.
It is also possible to provide a larger number of pressure-sensitive detection means 1a to 1c and detect the carriage 20 based on their outputs.

Note that when a person's foot steps on the pressure-sensitive detection means 1a to 1c, for example, it is rare that the three switches of the pressure-sensitive detection means 1a to 1c are sequentially stepped on, so the sequential operation detection means described above almost never outputs an output. It can be said that no signal is generated. Furthermore, depending on how the sequential operation detection means are arranged, the number of pressure-sensitive detection means 1a to 1c can be two or more, and as a result, it is sufficient to have a plurality of pressure-sensitive detection means.

FIG. 5 is a plan view showing a shoe-wiping mat with a sound generation function according to a second embodiment of the present invention.

In the embodiment shown in FIG. 5, a person gets on the pressure-sensitive detection means 1a to 1e from the lower side of the figure, and a trolley 20 approaches the pressure-sensitive detection means 1a to 1e. 4 is
All of them are arranged on the side surfaces of the pressure sensitive detection means 1a to 1e. Further, the sound generating means 4 may be composed of a piezoelectric vibrator, but the number of piezoelectric vibrators may be one (although a large number may be used to increase the sound volume).

In the shoe-wiping mat with sound generation function of each of the above embodiments, the control means 2, the power source 3, and the sound generation means 4 may be arranged at the corner or bottom of the shoe-wiping mat as shown in the figure, even if the location is not as shown in the figure. It's good to have.

In this way, the shoe cleaning mat with sound generation function according to the embodiment of the present invention!・Includes pressure-sensitive detection means 1a to lc, la to 1e, a control means 2 for driving the sound generation means 4 by the output signals of the pressure-sensitive detection means 1a to 1c, and the sound generation means 4. Among these, the control means 2 includes a first delay means 11 for performing leading edge delay to delay the output signal of the pressure sensitive detection means 1a;
a second delay means 12 that performs a leading edge delay to delay the output signal of the pressure sensitive detection means 1b; output signals of the first delay means 11 and the second delay means 12; and the pressure sensitive detection means 1c.
an AND gate 13 to which the output signal of the AND gate 13 is input, a recording/reproducing means 14 to which the output signal of the AND gate 13 is input, and a sound generating means 4, and the sound generating means 4 generates a warning sound or a message. It is something.

However, since the movement of the truck 2° is detected as the output of the control means 2, this output can also be used as a signal to stop the elevator 17 or stop the door 18 of the elevator 17 from closing.

The sound generating means 4 that generates sound according to the output of the control means in the above embodiment uses a speaker constructed using a piezoelectric vibrator due to its usage conditions, but when implementing the present invention, other speakers may be used. This does not negate the use of speakers.

Further, the shoe cleaning mat that accommodates the pressure sensitive detection means 1a to IC, the control means 2, and the sound generation means 4 of the above embodiment is composed of the mat base 5b and the flocked mat 5a, but the present invention can be implemented. In this case, it is possible to use an integrated shoe-wiping mat in which the mat base 5b and the flocked mat 5a cannot be separated, that is, the entire shoe-wiping mat is made of synthetic rubber, or the base 0 is made of synthetic rubber. can be,
