1. Field of the Invention
The present invention relates generally to an air discharge valve assembly for discharging air from the interior of a compressing-and-storing bag to compress and store an item and, more particularly, to an air discharge valve assembly for a clothing compressing-and-storing bag which smoothly discharges air from the compressing-and-storing bag and effectively prevents the entry of external air into the bag due to air-tightness, thus improving the efficiency of use, efficiently preventing the entry of moisture or mold into the bag, and enabling convenient storage of the bag by hanging it as one hangs a hanger.
2. Description of the Related Art
Generally, a compressing-and-storing bag has been used to compress and store bedding or the like after it has been put into the bag and air is discharged therefrom.
Since such a compressing-and-storing bag minimizes the volume of bedding, the compressing-and-storing bag makes it easy to store and carry the bedding and in addition keeps out moisture or mold, thus effectively storing and managing the bedding.
The compressing-and-storing bag may compress and store items of clothing as well as bedding.
That is, the compressing-and-storing bag includes a bag body which is made of a synthetic resin sheet and receives bedding, clothing or other items, and an air discharge valve which is attached to the bag body and is used to discharge the air from the bag.
Thus, after the bedding or clothing is put into the compressing-and-storing bag and the opening is closed, the air is drawn and discharged through the air discharge valve by means of a vacuum cleaner or another evacuation device. Thus, the bedding or clothing in the compressing-and-storing bag is compressed into a reduced volume.
The air discharge valve is the most important part of the compressing-and-storing bag. The present inventor has filed a number of Korean patent and utility model applications regarding air discharge valves for compressing-and-storing bags.
Korean Utility Model Registration No. 20-414999 discloses an air discharge valve as shown in
In this air discharge valve, while the lever 6 is moved up and down, the air passage is opened or closed. When the O-ring 7 of the lever 6 is inserted into the annular bottom groove 3a of the main body 3, the sidewall and bottom wall of the O-ring 7 are brought into air-tight contact with the annular bottom groove 3a and the contact protrusion 3b.
In the air discharge valve set forth above, however, the O-ring 7 is in frictional contact with the annular bottom groove 3a of the main body 3 as the O-ring 7 is moved up and down together with the lever 6. For this reason, the O-ring 7 may be separated from the lever 6, which in turn may destroy the air-tightness.
In an effort to overcome such a problem, Korean Patent No. 10-684669 discloses an air discharge valve as shown in
In this air discharge valve, as the lever 6 is moved up and down, the air passage is opened or closed. The stepped contact surface 6-1 of the lever 6 is in close contact with the inside portion of the packing 8 which is supported between the packing-receiving groove 3-1 of the main body 3 and the support protrusion 4-1 of the support plate 4 to provide an air-tight operation.
In the air discharge valve noted above, however, the support protrusion 4-1 of the support plate 4 protrudes into the internal space 5. Such a construction obstructs the flow of air in the internal space 5, thus reducing the operability of the air discharge valve.
In addition, with the air discharge valves filed by the present inventor, all of the vertical guide structure of the lever 6 provided at the center of the support plate 4 and the air flow passage are exposed to the outside. Thus, the air discharge valve suffers from a reduction in air-tightness. The air discharge valve has another problem in that foreign materials or moisture may be introduced into the air passage.
Further, all the compressing-and-storing bags which were previously filed by the present inventor are used to store bedding, clothing or the like. Especially in the case of storing clothing, it is difficult to store it neatly such that it does not lean to one side in the bag, and it is difficult to conveniently store the compressing-and-storing bag in the same way as one does clothing.
Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide an air discharge valve assembly for a clothing compressing-and-storing bag which improves the assembly structure of a main body, a cover, a lever and a packing, thus allowing air to be smoothly discharged from the compression-and-storing bag and effectively preventing the entry of external air into the bag by virtue of being air-tight, therefore improving the efficiency of use, and efficiently preventing the entry of moisture or mold into the bag.
Another object of the present invention is to provide an air discharge valve assembly for a clothing compressing-and-storing bag which allows a plurality of garments to be effectively stored in the compression-and-storing bag by hanging the garments in the form of being hung on a coat hanger, and allows the compression-and-storing bag to be conveniently stored by hanging it in the form of a coat hanger.

The operation of the present invention constructed as described above will be described below.
According to the present invention, after clothing or a similar item is put into the compressing-and-storing bag 2, the bag 2 is closed.
At this time, the clothing hung on an additional coat hanger 300 is put into the compressing-and-storing bag 2. The coat hanger 300 is inserted into and supported by the hanger holding holes 210 of the hanger holding unit 200 which is fitted into the lower assembly hole 70 of the air discharge valve 1.
Such a construction prevents the clothing from leaning to one side and allows the clothing to be neatly stored when the compressing-and-storing bag 2 is hung and stored in the fashion of a coat hanger.
In this way, a plurality of garments is put into and stored in the compressing-and-storing bag 2.
In such a state, air is discharged from the compressing-and-storing bag 2, so that the volume in the compressing-and-storing bag 2 is minimized and thus the clothing in the compressing-and-storing bag 2 is effectively stored.
First, the hanger body 120 of the hanger assembly 100 coupled to the upper portion of the air discharge valve 1 is rotated downwards around the hanger support parts 110 of the main body 10.
Here, the locking pieces 123 of the assembly parts 121 provided on both sides of the hanger body 120 are rotatably inserted into and supported to the assembly holes 112 of the hanger support parts 110.
Thereafter, after a suction nozzle of a vacuum cleaner or the like comes into close contact with the upper portion of the cover 20 of the air discharge valve 1, a suction operation is performed. Thereby, the opening operation of pulling the lever 40 upwards is conducted.
When the lever 40 is pulled up as such, the plug 60 coupled to the upper portion of the lever 40 is moved up, the upper air passage 12 of the cover 20 is opened. Further, the horizontal and vertical contact surfaces 46 and 47 formed in the contact groove 45 of the lever 40 are moved away from the horizontal and vertical support surfaces 56 and 57 formed in the inner contact part 55 of the packing 50, so that the air passage 11 is opened.
In this way, the air passage 11 of the main body 10 and the air passage 21 of the cover 20 are opened, so that air in the bag 2 is drawn and discharged sequentially through the lower air passage 11, the internal space 30 and the upper air passage 21.
At this time, the outer contact part 51 of the packing 50 is pressed and supported between the support surface 13 of the main body 10 and the support surface 23 of the cover 20, so that firm assembly is realized and a support protrusion protruding into a space to support the packing is not required unlike the prior art, and thus the element obstructing the flow of air is eliminated. Thereby, the operation of drawing and discharging the air is smoothly performed.
When the air is completely discharged from the bag 2, so that the compression is completed, the suction nozzle of the vacuum cleaner is removed from the upper portion of the cover 20.
As such, when the suction nozzle has been removed, the suction force through the suction nozzle is eliminated. At this time, due to the difference between internal and external pressures, the lever 40 moves downwards and returns to its original position. Thereby, the closing operation is performed.
That is, the horizontal and vertical contact surfaces 46 and 47 provided on the contact groove 45 of the lever 40 are in close contact with the horizontal and vertical support surfaces 56 and 57 formed in the inner contact part 55 of the packing 50 in horizontal and vertical directions, thus providing an airtight sealing operation.
Particularly, the pressure protrusion 44 protruding downwards from the horizontal contact surface 46 of the lever 40 presses the horizontal support surface 56 of the packing 50, thus achieving a more excellent airtight sealing operation.
Further, as the sealing operation is performed by the downward movement of the lever 40, the plug 60 moves downwards and returns to its original position, thus closing the upper portion of the cover 20. Thus, the guide hole 22 and the air passage 21 of the cover 20 are closed, thus preventing foreign materials and moisture from entering the bag 2, in addition to achieving more excellent sealing.
In this way, when the compression of the compressing-and-storing bag 2 has been completed, the hanger body 120 of the hanger assembly 100 coupled to the upper portion of the main body 10 of the air discharge valve 1 is rotated upwards and returns to its original position.
In such a state, using the hanger hook 130 coupled to the upper portion of the hanger body 120, the bag 2 is conveniently hung in a wardrobe or other space for storing clothing in a manner similar to that of hanging a coat hanger.
At this time, as described above, while the clothing stored in the compressing-and-storing bag 2 is hung on the additional coat hanger 300, it is hung on and supported by the hanger holding hole 210 of the hanger holding unit 200 which is assembled with the air discharge valve 1. Thus, during storage, the clothing does not lean to one side and is neatly stored.
Meanwhile, the hanger assembly 100 of the present invention is conveniently connected to the air discharge valve 1. That is, the assembly parts 121 provided on both sides of the hanger body 120 are inserted into the assembly holes 112 of the hanger support parts 110 protruding upwards from both sides of the main body 10 of the air discharge valve 1.
Each assembly part 121 of the hanger body 120 has the “U”-shaped body 122 and the locking pieces 123 provided on the opposite sides of the body 122. The locking pieces 123 are elastically inserted into the corresponding assembly holes 112 of the hanger support parts 110, so that the removal of the hanger body 120 from the air discharge valve 1 is prevented.
Particularly, the assembly parts 121 of the hanger body 120 are conveniently fitted into the assembly holes 112 of the hanger support parts 110 along the grooves 113, each of which has a small thickness and is formed along a predetermined portion of the upper circumference of each assembly hole 112.
The insert rod 131 of the hanger hook 130 is rotatably inserted into the assembly hole 125 which is formed in the center of the upper portion of the hanger body 120.
Here, the locking step 132 provided on the insert rod 131 of the hanger hook 130 is elastically supported by the elastic support part 126 which is formed in the assembly hole 125 of the hanger body 120.
Further, the insert rod 220 provided on the upper portion of the hanger holding unit 200 is rotatably inserted into the assembly hole 70 which is formed in the center of the lower portion of the main body 10 of the air discharge valve 1.
Here, the locking step 222 which is provided on the insert rod 220 of the hanger holding unit 200 is elastically supported by the elastic support part 71 which is formed in the assembly hole 70 of the main body 10.
Thus, the hanger assembly 100 and the hanger holding unit 200 of the present invention are conveniently mounted to the upper and lower portions of the air discharge valve 1, respectively.
As described above, the present invention provides an air discharge valve assembly for a clothing compressing-and-storing bag which improves the assembly structure of a main body, a cover, a lever and a packing, thus allowing air to be smoothly discharged from the compression-and-storing bag and effectively preventing the entry of external air into the bag by virtue of being air-tight, therefore improving the efficiency of use, and efficiently preventing the entry of moisture or mold into the bag. Further, the present invention allows a plurality of garments to be effectively stored in the compression-and-storing bag by hanging the garments in the form of being hung on a coat hanger, and allows the compression-and-storing bag itself to be conveniently stored by hanging it in the form of a coat hanger.
Although the preferred embodiment of the present invention has been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
