BEDCLOTHES

Technical Field

[1] The present invention relates to an air discharge valve for a compression and custody device of bedclothes, in particular to an air discharge valve for a compression and custody device of bedclothes, in which a cap of a compression pack for controlling the discharge and shut off of an air is enhanced as a structure of one-touch type to thereby improve the durability and airtight property of the discharge valve, and compression of the custody device can be rapidly progressed and damage of a vacuum cleaner can be prevented by compressing the custody device through using the principle of spray while ascending and descending the cap at the time of compression of the custody device. Background Art

[2] In general, bedclothes, clothing and the like has several problems in its custody in that a large space is occupied to keep them, various kinds of molds are apt to be grown therein due to the moisture, and worms flourish therein.

[3] The compression and vacuum custody device for the bedclothes is revised to keep the bedclothes, clothing and the like safely and efficiently. The general vacuum custody device comprises an inlet portion which can be opened and closed, and an air discharge valve for discharging air installed at a proper position of the device, so that the volume of the bedclothes and the clothing and the like can be reduced by discharging the inside air of the custody device by means of the suction force of the vacuum cleaner connected to the air discharge opening, when the bedclothes, the clothing and the like are put into the custody device after opening the inlet portion, and then closed.

[4] FIGs. 10 and 11 are perspective view and cross-sectional view showing the con¬ ventional air discharge valve of the vacuum custody device for the bedclothes.

[5] As shown in the drawings, in the conventional air discharge valve for the compression and custody device of bedclothes, a securing plate 120 is provided at a disc-shaped body 100 so that the securing plate 120 can be closely adhered to a proper position of the custody device, an air passage 150 is also provided at the center of the body 100, and a valve 200 for opening and closing the air passage 150 is installed at one side of the air passage 150 formed at the body.

[6] Such valve 200 is comprised of a securing shaft formed to extend from a bottom surface of an opening and closing member 220 for securing the opening and closing

member 200, which is transformed and opened and closed elastically, and an outer plate 260 connecting both ends of the opening and closing member 220 and supporting it.

[7] Referring to the operation of the conventional air discharge valve, as shown in a dotted line of FIG. 7, when the vacuum cleaner is activated after closely contacting an suction opening 300 of the vacuum cleaner with the valve, the opening and closing member 200 and the outer plate 260 are bent upwardly centering on a connection portion by the suction force of the vacuum cleaner to open the air passage 150 to thereby discharge the air in the custody device via the vacuum cleaner to the outside.

[8] Then, if the suction opening 300 of the vacuum cleaner has been disconnected from the air discharge opening after removing all the air in the custody device, the opening and closing member 220 returns to its original position by means of its elastic force. In this instance, as the atmospheric pressure in the upper side of the opening and closing member 200 is still larger than that of the inside of the vacuum custody device positioned below the opening and closing member, the opening and closing member 220 closely adheres and closes the air passage 150 to block the communication of air to thereby maintain the inside of the custody device under a vacuum condition.

[9] However, as the opening and closing member of the conventional air discharge opening is formed in a disc shape, and is supported only at both ends and its center, the opening of the discharge valve is opened only small and the elastic force of the opened valve is weak by the bending of the opening and closing member due to the suction of the vacuum cleaner, although it has been formed of an elastic materials, resulting in a problem that rapid closing of the air passage cannot be obtained after the disconnection of the suction opening of the vacuum cleaner.

[10] Also, according to the conventional prior art, if the vacuum cleaner is operated with the suction opening of the vacuum cleaner coming into close contact with the discharge valve, inside air of the compression and custody device can be sucked into the vacuum cleaner by the application of the strong suction force of the vacuum cleaner. However, at this time, excessive pressure is produced in the vacuum cleaner by the suction of the inside air in the compression and custody device without the inflow of the outside air, so that the suction opening of the vacuum cleaner is contracted to apply excessive pressure to the motor to thereby cause disorder in the vacuum cleaner.

[11] Further, as the vacuum cleaner will be operated continuously with the suction opening of the vacuum cleaner coming into close contact with the discharge valve, after the completion of the suction of the inside air of the compression and custody device and compression of the device, a user should take notice of the operation of the vacuum cleaner. If the vacuum cleaner is operated continuously when suction of the

inside air of the compression and custody device has been completed, excessive pressure is applied to the vacuum cleaner to thereby cause disorder of the cleaner. Ac¬ cordingly, a user has avoided using the compression and custody device of the con¬ ventional prior art owing to such problems, in spite of its advantages that it is possible to compress the compression and custody device effectively and keep it sanitarily. Disclosure of Invention Technical Problem

[12] The present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide an air discharge valve for a compression and custody device of bedclothes, in which a cap of a compression pack for moving a discharge valve upwardly an downwardly for controlling the discharge and blocking of air is enhanced as an opening or closing structure to thereby improve the durability and airtight property of the discharge valve, and compression of the custody device can be rapidly progressed and damage of a vacuum cleaner can be prevented by compressing the custody device by using the principle of spraying while ascending and descending the cap at the time of compression of the custody device. Technical Solution

[13] To accomplish the above object, according to the present invention, there is provided an air discharge valve for the compression and custody device of bedclothes, comprising a disc-shaped securing plate secured to a desired position of the custody device and having an air passage opened at the center, sealing means installed inside of the air passage of the securing plate and moves upwardly and downwardly slidably to be opened and closed, and support means for preventing the separation of the discharge valve and guiding it to be opened and closed.

Advantageous Effects

Best Mode for Carrying Out the Invention

[27] Hereinafter, the air discharge valve for the compression and custody device of the bedclothes of the present invention will be described in detail with reference to the appended drawings. In the drawings, the same reference numerals are used to designate the same or similar components through all the drawings, and so repetition of the de¬ scription on the same or similar components will be omitted.

[28] As shown in the drawings, the air discharge valve for the compression and custody device of the present invention is comprised of a body 10 having a disc-shaped securing plate 12 at the outer peripheral edge so that it can come into close contact with a proper position of the compression and custody device of the bedclothes, a valve 2 of a sealing means provided with a cylindrical air passage 15 formed at the central lower side of the body 10, which is installed inside of an air passage 15 and moves upwardly an downwardly slidably for controlling the flow of the air in the valve, and a support plate 8 for suppressing the disconnection of the discharge valve and width of upward and downward movement of the discharge valve.

[29] The discharge valve 2, which is a sealing means for opening and closing the air passage 15, is provided with a projection 20 at the central bottom surface so that they can pass through the inside wall of the air passage 15, and an o-ring 4 is inserted at a front end of the projection 20 so that the o-ring 4 can be closely adhered to the inside wall of the air passage 15 to thereby keep the airtight property. Also, a projection 22 is formed at the lower outer portion of the discharge valve so that the it is positioned at the inside of the support plate 8 to thereby prevent the discharge valve 2 from being broken away and allow the discharge valve 2 to move within proper intervals between

the upper and lower portion.

[30] In this instance, the projection 22 is formed with at least two air passages 15a so that they can be exposed to the outside at the time of moving to the upside to thereby induce the inside air of the compression and custody device and compress it, and lower dismal end of the projection 22 is formed with an engaging hook so that it is caught by the support plate 8 to thereby prevent the separation of the projection.

[31] The support plate 8, in which the discharge valve 2 is located and is closely adhered to the securing plate 12, is adapted to be engaged with the body 10 by means of the engaging groove 24 and the engaging projection 26, and is formed with an air inlet projection 28 in the radial direction at the upper surface to induce the inlet of the outside air to thereby separate a dismal end of the suction tube of the vacuum cleaner and the upper surface of the support plate 8 by proper intervals. Accordingly, when the vacuum cleaner is operated, it sucked the inside air of the custody device while inducing the inflow of the outside air to thereby move upwardly the discharge valve naturally to compress the custody device based on the Bernoulli s principle that, if the pressure in the upper surface of the discharge valve is reduced, it can be moved upwarldy by the suction force.

[32] FIG. 4 is a view showing another embodiment of the present invention. As shown in FIG. 4, a guide 13 is formed to project at the lower portion of the air passage 15 so that it is located inside of the projection 20 to allow air inlet through the side of the air passage, to thereby move upwardly an downwardly the discharge valve more stably to allow sucking of the inside air of the custody device.

[33] FIG. 5 is a view showing still another embodiment of the present invention. In this embodiment, a plate type opening and closing plate 30 is formed at upper portion of the air passage 15, and the projection 20a is formed to be shorter than before at the center of the discharge valve 2 to make it press the opening and closing plate 30 to control the flow of the air. In this instance, the outer peripheral edge of the opening and closing plate 30 is formed with an air discharge opening 32 made by cutting the outer peripheral edge into semi-circular shape to move the air.

[34] Further, the opening and closing plate 30 is preferable to be formed of elastic material, and the upper end of the air passage 15 is preferable to be formed with an adhesive projection 34 so that the opening and closing plate is completely adhered to keep sealing.

[35] FIGs. 6 to 9 are views showing the fourth embodiment of the present invention. In this embodiment, the discharge valve, which is a sealing means, for opening and closing the air passage 15 is formed to be semi-spherical shape at the central lower surface and is formed with an adhesive vane 40 at the lower outside so that it can be closely adhered to the upper portion of the air passage 15 to maintain the sealing, and

also the upper end of the discharge valve 2a is extended to the inside of the projection 20 so that the discharge valve 2a can move upwardly an downwardly without being separated.

[36] In this instance, a guide projection 44 having a different up and down height is pro- trudingly upwardly formed at the upper portion at the inside of the body 10 contacting with the outer surface of the adhesive vane 40 to induce the effective guide of the valve 2a. Also, owing to this difference of height of the guide projection, the inside air of the custody device can be emitted from a gap formed between the adhesive vane and the guide projection 44 via the air passage to be easily discharged.

[37] A cap 42 for compression pack including the discharge valve 2a and engaged with the body 10 is formed to be a cap closure shape, and is formed with an engaging projection 46 at the lower inside to be rotatably engaged with the engaging groove 48 formed at the upper portion of the body 10 to move upwardly an downwardly.

[38] A cap 42 for compression pack including the discharge valve 2a and engaged with the body 10 is formed to be a cap closure shape, and is formed with an engaging projection 46 at the lower inside to be rotatably engaged with the engaging groove 48 formed at the upper portion of the body 10 to move upwardly an downwardly.

[39] In this instance, as shown in FIG. 8, the lowest portion of the engaging groove 24 is formed to extend somewhat long in the rotational direction so that the cap can be engaged with tightly with rotation, a lower surface of a support member is formed with a reinforcing projection 50 in the radial direction to reinforce the body 10 more tightly, and the body 10 is adhesively secured to the custody device by installing a compression ring 54 below the engaging projection 26 formed below the engaging groove 48, and is completed by the compression ring to make the outer appearance beautiful.

[40] In this instance, a surface of the compression ring 54 is formed to project with an indication portion 56, which can be opened and closed, to facilitate the easy opening and closing of the cap 42, and prevent the end of the vacuum cleaner from being closely adhered to the compression ring 54 so that excessive pressure cannot be applied to the vacuum cleaner at the compression of the custody device.

[41] Further, a semi-circular discharge groove 58 is formed at the upper surface of the cap 42 so that air can be discharged through the groove. Mode for the Invention

[42] Hereinafter, the use state of the air discharge valve for the compression and custody device of the present invention will be described in detail with regard to the appended drawings.

[43] At first, a slide fastener provided to the compression and custody device for the

bedclothes is separated, and then the bedclothes to be kept is put into the compression and custody device, and the device is closed by closely adhering the slide fastener.

[44] When the vacuum cleaner is operated after closely adhering the compression and custody device and locating the suction opening 300 of the vacuum cleaner on the upper surface of the support plate 8, as shown in FIG. 2, the discharge valve 2 is sucked to the upper portion of the compression and custody device to suck the inside air to compress the compression and custody device.

[45] In this instance, the end of the suction opening 300 is closely adhered by the air inflowing projections 28 formed in the radial direction at the upper surface of the support plate 8 while being spaced apart by proper intervals, and when the vacuum cleaner is operated at this state, outer air is sucked concurrently to reduce the air pressure on the upper surface of the discharge valve to suck and upwardly move the discharge valve.

[46] In the ascended state of the discharge valve, the inside air of the compression and custody device can be sucked and compressed through the air passage 15 of the body 10 and the air passage 15a of the discharge valve. When the inside air of the compression and custody device has been entirely compressed, excessive pressure has been applied to the vacuum cleaner because there is no flow in of the outside air at the completion state of the suction of the inside air, in case of the conventional air discharge valve. However, according to the present invention, the outside air is always in-flowed by the air inducing projection 28 to thereby prevent the vacuum cleaner from being applied with the excessive pressure to compress the inside air of the compression and custody device stably.

[47] When the suction opening of the vacuum cleaner is disconnected after the completion of the suction of the inside air of the compression and custody device, as shown in FIG. 3, the discharge valve 2 is moved downward by the pressure difference to close the air passage at first, and if the discharge valve is further pressed downwardly at this state, it is contracted completely to a state shown in FIG. 1, to accomplish complete sealing of the compression and custody device.

[48] When the operation of the another embodiment of the present invention is to be explained, as described above, after the compression and custody device is sealed up and is moved above the cap 42 of the compression pack, when the vacuum cleaner is operated with the suction opening 300 of the vacuum cleaner positioned above the compression ring 54, the discharge valve 2a is sucked toward the upper portion to suck and compress the inside air of the compression and custody device.

[49] In this instance, the end of the suction opening 300 is engaged with the discharge valve while being spaced apart by proper intervals by means of the indication portion 56 formed to project from the upper surface of the compression ring 54, and when the

vacuum cleaner is operated at this state, the outside air is sucked concurrently with the inside air to reduce the pressure in the upper surface of the discharge valve so that the discharge valve 2a can be sucked up to the upside.

[50] In the ascended state of the discharge valve, the inside air of the compression and custody device can be sucked and compressed through the air passage 15 of the body 10 and the discharge groove 58 formed at the upper surface of the cap.

[51] When the inside air of the compression and custody device has been entirely compressed, excessive pressure has been applied to the vacuum cleaner because there is no inflow of the outside air at the completion state of the suction of the inside air, in case of the conventional air discharge valve. However, according to the present invention, the outside air is always in-flowed by the indication portion 56 to thereby prevent the vacuum cleaner from being applied with the excessive pressure to compress the inside air of the compression and custody device stably.

[52] If the suction opening of the vacuum cleaner is disconnected after the completion of the suction of the inside air of the compression and custody device, as shown in FIG. 6, the discharge valve 2 is moved downward by the pressure difference to seal up the air passage at first, and if the discharge valve is further pressed downward and rotated at this state, it is contracted completely to accomplish complete sealing of the compression and custody device. Industrial Applicability

[53] As described above, according to the air discharge valve for the compression and custody device of bedclothes of the present invention, it is possible to prevent the vacuum cleaner from being applied with the excessive pressure because the inside air of the compression and custody device can be sucked together with the outside air at the time of sucking the inside air of the compression and custody device.

[54] Also, it is easy and simple to discharge the air because the air passage can be controlled according to the ascending and descending of the discharge valve.

[55] While the present invention has been described with reference to the preferred em¬ bodiments, the present invention is not limited by the embodiments. It is to be understood that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention. However, such variations and modifications are all pertained to the scope of the present invention. Sequence Listing
