Description

Technical Field

[0001] The present invention relates to an air cushion embedded storage space structure formed of a three-dimensional fabric. More specifically, when an air cushion inflated by air pressure is manufactured by forming an airtight coating on the outer side of a three-dimensional fabric woven in a manner of connecting the space between two opposite woven surfaces using a plurality of pile yarns, an independent space is provided to hide electrical components such as speakers for generating audio and vibration and an air pump for inflation inside, thereby preventing the electrical components from being exposed while maintaining the characteristic of transmitting audio through the pile yarns, thereby improving convenience and aesthetics in use. Background Art

[0002] Generally, when air is injected into a tubular air mattress made of plastic, the material is stretched and deformed due to the expansion pressure, and the air pressure drops. In order to maintain the appropriate air pressure, the air needs to be replenished at all times, which causes many inconveniences. In addition, while maintaining the optimal air pressure, the ability to evenly support or distribute the body weight weakens and the stability decreases. Therefore, in terms of cost, it is not suitable for long-term use as a bed.

[0003] In order to improve the problems existing in the air cushion made of the plastic material, an air cushion made of three-dimensional fabric has been proposed. The air cushion uses a three-dimensional fabric woven in a manner that utilizes a plurality of pile yarns to connect the space between two opposite woven surfaces as a base, and a coating made of an elastic (Elastomer) material is formed on the outer side of the fabric to maintain air tightness. Therefore, when air is injected, the pile yarns connecting the two woven surfaces on both sides formed as one body with the coating maintain a predetermined air pressure, and maintain a stable air pressure corresponding to the load applied from the outside.

[0004] Air cushions based on this three-dimensional fabric have high durability while maintaining stable air pressure. Therefore, they are widely used in various fields such as various entertainment facilities and sporting goods with sealed air layers.

[0005] In particular, Korean Patent No. 10-0684071 previously applied by the applicant of the present invention has proposed a vibration system of an air cushion through a speaker box. In order to replace the spring mattress used for the bed, an air cushion made of three-dimensional fabric is manufactured, and a speaker of an audio device is set on its outer side. The audio diffused by the speaker is converted into a vibration proportional to the amplitude of the audio through a sealed air layer and a plurality of wires vertically connected to the space portion as a medium, and applied to the entire part of the air cushion. Therefore, when lying on the air cushion, while enjoying the music through hearing, the music can be felt through the body in contact with the air cushion.

[0006] That is, the prior granted patent, such asFigure 1 and Figure 2 As shown, when making the air cushion 20 for the bed 10, a plurality of pile yarns W are used to vertically connect the upper woven surface 2 and the lower woven surface 3 to weave a three-dimensional fabric. The three-dimensional fabric is used as a base, and a coating made of elastic material for blocking air is formed on the inner or outer surface. Durability and pressure resistance are ensured by the air pressure filled inside. In this state, a speaker 30 is arranged on the outer side of the air cushion 20 to play and diffuse the audio signal generated by an audio device 31 such as an audio or video. Thereby, the audio transmitted from the speaker is uniformly applied to the top of the air cushion where someone is lying through the plurality of pile yarns inside, so that the person lying on the air cushion can feel the audio through hearing and body.

[0007] However, the structure of the vibration system of the air cushion made of the three-dimensional fabric through the speaker sound is that the speaker, sound equipment and electrical components such as the air pump for inflation are exposed to the outside of the air cushion, and then, the wires for transmitting electrical signals are arranged or the air supply pipe is connected. Due to this structure, the number of electrical components exposed to the outside of the air cushion increases with the type of electrical components, which not only brings inconvenience to the handling and use of the air cushion, but also causes a problem of poor aesthetics due to the electrical components, wiring and pipes exposed to the outside.

[0008] In particular, Figure 2 As shown, in order to effectively diffuse the vibrations generated by the sound, when a speaker is installed on the bottom surface of the air cushion, it is necessary to form a space for accommodating the speaker on the lower frame supporting the air cushion. Therefore, there is a problem that not only is the production of the lower frame complicated, but the installation space of the speaker is extremely limited. Summary of the invention

[0009] Technical issues

[0010] The present invention is invented in view of the above-mentioned existing problems, namely the problems caused when the speakers are set on the outside of the air cushion and are exposed, and its purpose is to provide an air cushion embedded storage space structure made of three-dimensional fabric, which provides an independent space for hiding electrical components such as speakers and air pumps that generate vibrations by sound while maintaining the characteristics of transmitting audio through pile yarns inside the air cushion with three-dimensional fabric as the base. Thereby, the electrical components can be prevented from being exposed to the outside and the ease of use and aesthetics can be improved.

[0011] Technical Solution

[0012] In order to achieve the above-mentioned purpose, the present invention provides an air cushion embedded storage space structure formed by a three-dimensional fabric, wherein the air cushion is based on a three-dimensional fabric woven by vertically connecting a plurality of pile yarns between an upper woven surface and a lower woven surface opposite to each other, a coating for blocking air is formed on the outer side surface, and the expanded state is maintained by the air pressure injected into the interior. While the vibration characteristics of the pile yarns are maintained inside the air cushion, the structure providing an independent space is composed of a cylindrical box body and a cylindrical isolation part joined together, wherein the upper part of the cylindrical box body is blocked by a flange formed on the outer peripheral surface of the opening part, so that electrical components such as a speaker for transmitting audio through the opening part set on the bottom surface and an air pump for inflation can be selectively accommodated, and the cylindrical isolation part, in the upper part of the box body, has a plurality of pile yarns woven vertically connected between the upper woven surface and the lower woven surface, and the side of the cylindrical isolation part is opened when coatings are formed on the outer sides of the upper woven surface and the lower woven surface respectively.

[0013] Technical Effects

[0014] The embedded storage space structure of the air cushion made of three-dimensional fabric according to the present invention has the following advantages: a box body and an isolating portion structure having a stacked structure are inserted and joined under the air cushion with the three-dimensional fabric as the base or in a circular hole formed through the top and bottom, and then, after inserting electrical components such as speakers, audio equipment or air pumps through the opening of the box body, the opening is covered with a cover, thereby making it possible to hide the electrical components from being exposed to the outside of the air cushion, thereby improving the appearance, and the entire part of the air cushion maintains a uniform pressure and remains in an expanded state for a long time, thereby improving ease of use, and the vibration of the speaker set in the box body can be diffused by the pile yarn constituting the isolating portion of the structure.

[0020] Next, the embedded accommodation space structure of the air cushion made of three-dimensional fabric of the present invention is described as follows with reference to the accompanying drawings.

[0021] Figure 3 and Figure 4 is a three-dimensional diagram and a cross-sectional diagram showing the storage space structure of the present invention, Figure 5 and Figure 6 The present invention relates to a structure 100, which is based on a three-dimensional fabric woven by vertically connecting a plurality of pile yarns W between an upper woven surface 2 and a lower woven surface 3 facing each other, and is based on a premise that an air cushion 20 is maintained in an expanded state by the air pressure injected into the interior, and the vibration characteristics of the pile yarns are maintained inside the air cushion, and an independent space is provided.

[0022] The structure 100 is composed of a cylindrical box body 110 and a cylindrical isolation part 120 joined together as one body, wherein the upper part of the cylindrical box body 110 is blocked by a flange 112 formed on the outer peripheral surface of the opening part, so as to selectively accommodate electrical components such as a speaker that transmits audio through an opening part 111 set on the bottom surface and an air pump for inflation, and the cylindrical isolation part 120, at the upper part of the box body, is the same as the three-dimensional fabric that serves as the base of the air cushion 20, and a plurality of pile yarns W` are woven vertically and connected between the upper woven surface 121 and the lower woven surface 122, and the side of the cylindrical isolation part is opened while a coating 123 made of elastic (Elastomer) material is formed on the outer sides of the upper woven surface and the lower woven surface respectively.

[0023] When the structure 100 is manufactured by joining the isolation part 120 made of three-dimensional fabric on the top of the box body 110, it is preferred that the box body 110 and the isolation part 120 are formed to have the same outer diameter. At this time, the upper and lower parts are formed to have the same ratio, and the other parts except the flange 112 formed at the lower end of the box body 110 are formed to have the same height as the air cushion 20.

[0024] When the structure 100 of the present invention is inserted into the interior of the air cushion 20 in a hidden manner, as shown in FIG. Figure 5As shown, at least one portion of the air cushion 20 is selected to penetrate through the upper and lower parts to form circular holes H with the same inner diameter for inserting the box 110 and the isolation part 120, and then the structure 100 is inserted upward from the lower part of the hole H.

[0025] That is, when the structure 100 is inserted into the hole H formed on the air cushion 20, as shown in FIG. Figure 6 As shown, the flange 112 at the lower end of the box body 110 is tightly attached to the outer side surface of the hole H on the lower side, and the circular coating 123 formed on the upper side of the isolation part 120 enters the inner peripheral surface of the hole H on the upper side of the air cushion 20 while being located on the same line. In this state, the coating 123 that is in contact on both sides with the hole H as the boundary is connected to the annular connector 130 that integrates a part of the air cushion 20.

[0026] Since the coating 123 constituting the structure 100 and the surface coating of the air cushion 20 and the connecting member 130 are made of the same type of elastic material, they are preferably heated and bonded to each other to improve durability, but may also be bonded using an adhesive.

[0027] Figure 7 and Figure 8 1 is a cross-sectional structural diagram of another embodiment showing the state before and after the air cushion having the three-dimensional fabric is provided with a storage space structure. Figure 5 and Figure 6 In the embodiment, a circular hole H is formed passing through the upper and lower parts of the air cushion 20, and the structure 100 is inserted therein. However, another feature of the present invention is that after the circular hole H is formed on the bottom of the air cushion 20, the pile yarn W remaining in the hole is removed, and in this state, the structure 100 is inserted and the upper side coating 123 is engaged with the inner side surface of the air cushion 20 to contact each other.

[0028] Fig. 9 It is a cross-sectional structural diagram showing an example of installing electrical components in a storage space structure provided inside the air cushion of the present invention. After a structure 100 having a stacked structure and a box body 110 and an isolation portion 120 is inserted and joined into a circular hole H formed below or through the upper and lower parts of the air cushion 20, electrical components such as speakers, audio equipment, or air pumps are inserted through an opening 111 of the box body 110. Then, the opening is covered with a cover C to conceal the electrical components without exposing them to the outside of the air cushion. Furthermore, since the entire part of the air cushion maintains a uniform pressure and remains in an expanded state for a long time, the convenience of use can be improved.

[0029] Although there is a limitation that the length of the pile yarn W' constituting the isolation part 120 of the structure 100 is slightly shorter than the length of the pile yarn W constituting the air cushion 20, it has been confirmed through repeated experiments that it does not hinder the diffusion of the vibration generated by the sound of the speaker installed in the box 110.
