BACKGROUND OF THE INVENTION
The present invention relates to a rug member that forms a mat that produces a sound when connected and serves as a toy musical instrument that produces a sound by hand pressing or stepping alone.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is a plate in which unevenness is provided on a peripheral edge of a plate, and adjacent plates are fitted to the unevenness and connected to form a rug (for example, see Patent Document 1).
In addition, there is a hand-pushed musical instrument in which a hollow is provided in an elastic body having a size that can be held in a hand and a cylindrical whistle is fixed in a through hole between the outer peripheral side walls (see, for example, Patent Document 2).

[0004]
[Problems to be solved by the invention]
The plate of Patent Document 1 can be connected to form a mat, but it is not a musical instrument, and even if a whistle is attached to the outer peripheral wall of the plate, if connected, the mouth of the cylinder is blocked and air cannot enter and exit, and no sound is emitted. .
The hand-held musical instrument of Patent Document 2 cannot be connected to be a rug.
An object of the present invention is to provide a sounding rug member that can be connected to form a sounding rug (mat) and that can be used alone as a hand-held or stepping toy musical instrument.
[0005]
[Means for Solving the Problems]
A body having a hollow elastic plate provided with convex portions and concave portions alternately on the periphery, and provided with through holes communicating with the hollow, opening at the front end wall surface of the convex portions and / or the inner surface of the concave portion. A whistle that makes a sound by the outflow or inflow of air is inserted into and fixed to the through hole, and an air flow passage is provided in front of the opening of the whistle. A rug can be formed by squeezing and connecting the convex portions of the rug member having the same shape to the concave portions of other rug members.
[0006]
In the air flow path, make the length of the convex part with the whistle slightly shorter than the length of the other convex part, or make the depth to the inner surface of the concave part with the whistle smaller than the depth of the other concave part. It is assumed that a gap is formed on the front surface of the whistle opening when the two rug members are connected to each other slightly deeper.
[0007]
When the air flow passage is provided with a groove connected to the peripheral wall of the rug member, that is, the tip wall and the side wall of the convex part, and the side wall and the back wall of the concave part, the two rug members are connected. The grooves are opposed to each other to form a tunnel, and the air of the whistle fitted and fixed in the through hole communicating with the inside of the groove and the hollow of the main body is allowed to flow.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
A rug member according to the present invention will be described with reference to the drawings.
Protrusions 2 and recesses 3 are provided alternately and continuously on the periphery of a plate-like main body 1 made of an elastic body such as rubber or plastic, a hollow 4 is provided inside, an opening is formed in the peripheral wall of the main body 1, and a hollow 4 is formed. One or a plurality of through-holes 5 are provided, and a whistle 6 that makes a sound due to inflow and outflow of air is fitted and attached to each through-hole 5 to form a rug member 7.
[0009]
The convex portion 2 has a shape that fits with the concave portion 3 of the other rug member 7 having the same shape, and the concave portion 3 has a shape that fits with the convex portion 2 of the other rug member 7 having the same shape.
[0010]
Although the formation method of the hollow 4 is not limited, it can be formed by the following method.
That is, the main body 1 has three layers, and a hole having a size of a flat shape of the hollow 4 is provided in the middle portion of the intermediate layer to form a frame shape, and a notch capable of fitting a whistle is provided at a desired position of the frame. The intermediate layer is sandwiched between two plates and bonded.
Alternatively, the plate is provided with a hollow 4 flat-shaped concave portion on the plate, is provided with an intermediate notch that can be fitted with a whistle at a desired portion of the plate-like edge, and the plate is placed above the plate-like shape. Glue and cover.
In any case, a through hole into which a whistle can be inserted after bonding may be provided without providing a notch.
[0011]
The rug member 7 shown in FIG. 1 shows a through hole 5 provided between the tip wall of the convex portion 2 and the hollow 4, and the rug member 7 shown in FIG. 3 has the through hole 5 at the back of the concave portion 3. What was provided between the wall surface and the hollow 4 is shown.
[0012]
When the two rug members 7 are connected by fitting the concavo-convex portions, it is necessary to prevent the opening of the whistle 6 from being blocked by the peripheral wall of the other rug member 7.
[0013]
In the rug member 7 shown in FIG. 1, the length of the convex portion 2 a provided with the through hole 5 is made slightly shorter than the depth of the concave portion 3. That is, the gap 9 is provided between the virtual surface 8 connecting the tip surfaces of the other protrusions 2 and the tip surface of the protrusions 2a.
FIG. 2 shows a connected state of the rug member 7 having the above-described configuration. A gap 9 is formed in front of the opening of the whistle 6 so as not to prevent inflow and discharge of air.
[0014]
In the rug member 7 shown in FIG. 3, the depth of the concave portion 3 a provided with the through hole 5 is made slightly larger than the length of the convex portion 2. That is, the gap 11 is provided between the virtual surface 10 that connects the back surface of the recess 3 a and the back surface of the other recess 3.
FIG. 4 shows a connected state of the rug member 7 having the above configuration. A gap 11 is formed in front of the opening of the whistle 6 so as not to prevent inflow and discharge of air.
[0015]
In the rug member 7 of the above embodiment, the convex portion is shortened or the depth of the concave portion is increased so as not to block the opening of the whistle 6 at the time of connection. Although the flow path is secured, there is a problem that a gap is generated in the connected rug.
It is preferable to configure the air flow passage of the rug member as follows so as not to create a gap.
[0016]
That is, as shown in FIG. 5, the groove 12 is surrounded by the peripheral wall of the main body 1 of the rug member 7. The groove 12 has a U-shaped cross section in the figure, but may have a circular arc shape or other shapes.
Then, the whistle 6 is fitted into the through-hole communicating with the hollow 4 at the location of the convex portion 2 or the concave portion 3 in the groove 12 and attached.
[0017]
When this type of rug member 7 is connected, two grooves 12 face each other on the connecting surface to form a tunnel, and the tunnel becomes an air flow path.
[0018]
The whistle 6 of the rug member 7 may be provided in one or a plurality of convex portions, one or a plurality of concave portions, or may be provided in a convex portion and a concave portion.
[0019]
When a plurality of whistles are attached to one rug member 7, the whistle having the same sound or different sounds may be used.
[0020]
One rug member 7 may be attached with a whistle that rings when the hollow upper surface is pushed and air flows out, or a whistle that sounds when the hollow upper surface is released and the air is inhaled. Alternatively, both a whistle that rings when air flows out and a whistle that sounds when air is inhaled may be attached.
[0021]
In order to distinguish the sound difference between the rug members, it is preferable to display symbols or patterns or change colors.
[0022]
【The invention's effect】
The rug member according to the present invention allows each person to play a melody by holding a rug member that makes a different sound and pressing it with a hand, or placing it on the floor or the ground and stepping on with a foot.
A chord can be played by stacking several pieces of rug members with different sounds and pressing them with your hand or by stepping on them with your feet.
A rug (mat) is formed by connecting several rug members, and a sound can be produced by walking or running on the rug. Also, several people line up on the rug, each of which can share multiple pieces and step on with your feet to make a melody.
