Description

Technical Field

[0006] ,

[0001] The present invention relates to an attachment for a futon compression bag, and more particularly to an attachment for a futon compression bag that is used between the suction valve of the futon compression bag and the suction nozzle of a vacuum cleaner to prevent suction leakage by the vacuum cleaner.

Background Art

[0002] In recent years, when storing bedding such as futons, the bedding is stored in a futon compression bag, and the air in the futon compression bag is sucked by a vacuum cleaner, and at the same time, the air in the bedding is also sucked to reduce the overall volume and store it compactly.

[0003] Conventionally, to suck air from such a futon compression bag or the like with a vacuum cleaner, a suction valve is provided on the futon compression bag, and the tip of the suction nozzle of the vacuum cleaner is airtightly covered on this suction valve.

[0004] However, currently, various vacuum cleaners are sold by each manufacturer, and among their suction nozzles, there are some with a shape that cannot be airtightly covered on the suction valve. Therefore, a futon compression bag has been proposed that is composed of a valve body, a valve cover that covers the valve body, and a valve that is set in the central recess of the valve body and can open and close an air suction hole, and a seal bag into which the tip of the suction nozzle of the cleaner is inserted is attached to the valve cover (see Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, with the aforementioned vacuum storage bags for bedding, the tip of the suction nozzle was inserted into a flexible sealable bag, and suction was performed with the sealable bag wrapped around the tip of the suction nozzle. Therefore, it was necessary to wrap the sealable bag around the suction nozzle, and it was also necessary to hold it by hand to maintain that state. As described above, the suction operation with the above-mentioned vacuum storage bags for bedding was cumbersome.

[0007] This invention was made to solve the above problems, and aims to enable the easy and leak-free suction of air from a vacuum storage bag by using an attachment that can airtightly connect to suction nozzles of various shapes and also to vacuum storage bags. [Means for solving the problem]

[0008] The attachment for a futon compression bag according to claim 1 is characterized by comprising a nozzle joint that airtightly connects to the inner surface of the tip of the suction nozzle of a vacuum cleaner, and a futon compression bag joint that covers the suction valve of the futon compression bag and airtightly connects to the sheet of the futon compression bag by pressing against it.

[0009] The attachment for a futon compression bag according to claim 2 is characterized in that the nozzle joint is formed in a cylindrical cross-section, and the diameter of its outer surface increases as it approaches the futon compression bag joint.

[0010] The attachment for a futon compression bag according to claim 3 is characterized in that the outer surface of the nozzle joint is formed as a curved surface.

[0011] The attachment for a futon compression bag according to claim 4 is characterized in that the outer surface of the nozzle joint portion has a recess that is convex inward and has a larger diameter from near the upper end to the middle, and a convex portion that is convex outward and has a larger diameter, which is continuous with the recess.

[0012] The attachment for a futon compression bag according to claim 5 is characterized in that the nozzle joint portion is formed of an elastic material.

[0013] The attachment for a futon compression bag according to claim 6 is characterized in that the futon compression bag joining portion is formed in a dish shape.

[0014] The attachment for a futon compression bag according to claim 7 is characterized in that a recess corresponding to the projection of the vacuum cleaner's suction nozzle is formed at the joint portion of the futon compression bag.

[0015] The attachment for a futon compression bag according to claim 8 is characterized in that the futon compression bag joining portion has an inner cylinder surrounding the outer circumference of a suction valve, an outer cylinder formed on the outer circumference of the inner cylinder, and ribs connecting the inner cylinder and the outer cylinder.

[0016] The attachment for a futon compression bag according to claim 9 is characterized in that a ring portion extending substantially horizontally is formed on the outer peripheral edge of the lower end of the futon compression bag joint. [Effects of the invention]

[0017] In the attachment for a futon compression bag according to claim 1, the nozzle joint is configured to be airtightly joined to the inner surface of the tip of the suction nozzle of a vacuum cleaner. Therefore, the nozzle joint and the tip of the suction nozzle can be easily and airtightly joined simply by fitting the tip of the suction nozzle of the vacuum cleaner onto the nozzle joint (simply by inserting the nozzle joint into the tip of the suction nozzle). Furthermore, the futon compression bag joint can be airtightly joined by covering the suction valve of the futon compression bag and pressing it against the sheet of the futon compression bag. Therefore, the futon compression bag joint and the futon compression bag can be easily and airtightly joined. As a result, the suction nozzle tip and the suction valve can be kept airtight, preventing suction leakage and ensuring reliable compression of the futon compression bag.

[0018] In the attachment for a futon compression bag according to claim 2, the nozzle joint is formed in a cylindrical cross-section, and its outer diameter increases as it approaches the futon compression bag joint. Therefore, even if the inner diameter of the suction nozzle tip is different, a secure and airtight connection can be made. That is, the suction nozzle tip is fitted onto the nozzle joint for connection, but in the case of a suction nozzle tip with a small diameter, a tight connection is made at the smaller diameter portion at the top of the nozzle joint, and in the case of a suction nozzle tip with a large diameter, a tight connection is made at the larger diameter portion at the bottom of the nozzle joint. As described above, the futon compression bag can be reliably suctioned regardless of the inner diameter of the suction nozzle tip.

[0019] Therefore, by setting the outer diameter of the tip of the nozzle joint to be smaller than that of the smallest suction nozzle tip product, it is possible to make it compatible with all vacuum cleaners.

[0020] In the attachment for a futon compression bag according to claim 3, the outer surface of the nozzle joint is formed as a curved surface. Therefore, the contact area between the outer surface of the nozzle joint and the inner surface of the suction nozzle tip can be increased. That is, since the outer surface of the nozzle joint is curved in the vertical direction, the inner surface of the suction nozzle tip comes into contact with the curved surface in the vertical direction, resulting in a larger contact area than if it were simply a straight tapered shape. As a result, the futon compression bag can be sucked more reliably.

[0021] In the attachment for a futon compression bag according to claim 4, the outer surface of the nozzle joint portion has a recess that is convex inward and has a larger diameter from near the top to the middle, and a convex portion that is convex outward and has a larger diameter, continuing from the recess. That is, the diameter of the outer surface of the nozzle increases sequentially as it goes downwards, but the rate of change of the diameter of the outer surface of the nozzle joint portion increases sequentially from near the top to the middle, and then decreases sequentially from the middle to the bottom. Therefore, even with a suction nozzle with a small inner diameter, the joint will not be made near the top of the nozzle joint portion, but will be made when it reaches the middle of the nozzle joint portion. As a result, the length of the vertical overlap between the suction nozzle and the nozzle joint portion is increased, so a stable joint can be obtained.

[0022] In the attachment for a futon compression bag according to claim 5, the nozzle joint is made of an elastic material. Therefore, when the tip of the suction nozzle is pressed down and fitted onto the nozzle joint, the nozzle joint flexes, increasing the contact area and improving the tightness, so that the futon compression bag can be sucked more reliably.

[0023] In the attachment for a futon compression bag according to claim 6, the futon compression bag joining portion is formed in a dish shape. Therefore, by pressing the futon compression bag joining portion onto the futon compression bag so as to cover the suction valve, the futon compression bag joining portion and the futon compression bag can be airtightly joined.

[0024] In the attachment for a futon compression bag according to claim 7, a recess corresponding to the protrusion of the vacuum cleaner's suction nozzle is formed at the futon compression bag joint. Therefore, it can also be used with vacuum cleaners that have a suction nozzle with a protrusion.

[0025] In the attachment for the futon compression bag according to claim 8, the futon compression bag joint has an inner cylinder surrounding the outer periphery of the suction valve, an outer cylinder formed on the outer periphery of the inner cylinder, and ribs connecting the inner cylinder and the outer cylinder. Therefore, it is possible to maintain double airtightness, so that the futon compression bag joint and the futon compression bag can be more reliably joined airtightly. The futon compression bag joint and the futon compression bag can be joined airtightly.

[0026] The attachment for the futon compression bag according to claim 9 has an annular portion formed on the outer peripheral edge of the lower end of the futon compression bag joint and extending substantially horizontally. Therefore, since the annular portion adheres to the sheet of the futon compression bag with a certain area, airtightness can be more ensured, and air does not leak from between the futon compression bag joint and the sheet.

Brief Description of the Drawings

[0027] [Figure 1] Cross-sectional view showing the state of use of the first embodiment of the attachment for the futon compression bag according to the present invention [Figure 2] Plan view of the first embodiment of the attachment for the futon compression bag according to the present invention [Figure 3] Plan view of the second embodiment of the attachment for the futon compression bag according to the present invention [Figure 4] Longitudinal sectional view of the second embodiment of the attachment for the futon compression bag according to the present invention [Figure 5] Back view of the second embodiment of the attachment for the futon compression bag according to the present invention [Figure 6] Plan view of the third embodiment of the attachment for the futon compression bag according to the present invention [Figure 7] Longitudinal sectional view of the third embodiment of the attachment for the futon compression bag according to the present invention [Figure 8] Back view of the third embodiment of the attachment for the futon compression bag according to the present invention [Forms for implementing the invention]

[0028] The attachment for a futon compression bag according to the present invention consists of a nozzle joint that airtightly connects to the inner surface of the tip of the suction nozzle of a vacuum cleaner, and a futon compression bag joint that covers the suction valve of the futon compression bag and airtightly connects to the sheet of the futon compression bag by pressing against it. The nozzle joint is not particularly limited as long as it is configured to airtightly connect to the inner surface of the tip of the suction nozzle, but for example, it can be formed in a cylindrical shape in cross-section, and the diameter of its outer surface can increase as it approaches the futon compression bag joint. In this case, the outer surface of the nozzle joint can be straight, a curved surface that is convex outward or inward, or a combination of straight and curved surfaces. Furthermore, the material for the futon compression bag attachment is preferably an elastic member that has a certain degree of strength and flexibility, for example, polypropylene resin is preferred.

[0029] An embodiment of the attachment for a futon compression bag according to the present invention will be described with reference to the drawings. Figure 1 is a cross-sectional view showing the futon compression bag attachment in use, and Figure 2 is a plan view of the futon compression bag attachment.

[0030] In these figures, the attachment 1 for the futon compression bag consists of a nozzle joint 10 that airtightly connects to the tip of the vacuum cleaner's suction nozzle, and a futon compression bag joint 20 that is molded integrally with the nozzle joint 10 and airtightly connects to the sheet of the futon compression bag. The nozzle joint 10 is formed with a cylindrical cross-section, and the diameter of the outer surface 11 increases as it approaches the futon compression bag joint 20, that is, from the upper end to the lower end.

[0031] Furthermore, the outer surface 11 of the nozzle joint 10 is formed such that its longitudinal cross-section is curved. That is, it is formed as a curved surface that is convex outward from the upper end to the lower end, and its curvature is set to gradually decrease from the upper end to the lower end.

[0032] The aforementioned futon compression bag joint 20 is formed in an overall shape roughly like an inverted dish, and a space 21 for housing a suction valve is secured inside. A ring portion 22 is formed on its outer edge in a direction roughly perpendicular to it (horizontal direction).

[0033] The attachment 1 for the futon compression bag, consisting of the nozzle joint 10 and the futon compression bag joint 20, is integrally formed from an elastic member made of PP resin and has a structure that flexes slightly under external pressure.

[0034] The dimensions of attachment 1 for vacuum storage bags can be set arbitrarily, but as an example, they can be set to the following dimensions.

[0035] The diameter of the outer tip of the nozzle joint 10 is a: 28 mm, the diameter of the lower end of the outer surface of the nozzle joint 10 is b: 35 mm, the diameter of the futon compression bag joint 20 is c: 66 mm, the width of the ring portion 22 is d: 5 mm, and the height of the futon compression bag attachment is e: 39 mm.

[0036] To use the above-described attachment 1 for vacuum storage bags to vacuum a vacuum storage bag, as shown in Figure 1, the vacuum storage bag joint 20 is placed over the suction valve 31 of the vacuum storage bag 3 and housed in the space 21, and its annular portion 22 is placed on the outer sheet 32 ​​of the suction valve 31. Next, the tip 4 of the vacuum cleaner's suction nozzle is pressed over the nozzle joint 10 from above and below, so that the inner surface 41 of the suction nozzle tip 4 is pressed against the outer surface 11 of the nozzle joint 10. At this time, the outer surface 11 of the nozzle joint 10 flexes slightly, increasing the contact area between the inner surface 41 and the outer surface 11, and the elastic pressure causes them to adhere tightly. Therefore, no air leaks from between the inner surface 41 and the outer surface 11.

[0037] In this state, the attachment 1 for the vacuum storage bag is pressed against the vacuum storage bag 3. This causes the ring portion 22 to adhere tightly to the sheet 32, preventing air from leaking between the ring portion 22 and the sheet 32.

[0038] If the diameter of the inner surface 41 of the suction nozzle 4 exceeds 35 mm, the inner surface 41 will not be pressed against the outer surface 11 of the nozzle joint 10 as described above. However, airtightness can be similarly ensured by pressing the tip surface 42 of the suction nozzle 4 against the upper surface of the futon compression bag joint 20.

[0039] A second embodiment of the attachment for vacuum storage bags according to the present invention will be described with reference to the drawings. Figure 3 is a plan view of the attachment for vacuum storage bags, Figure 4 is a longitudinal cross-sectional view of the attachment for vacuum storage bags, and Figure 5 is a rear view of the attachment for vacuum storage bags.

[0040] In these figures, the attachment 1 for the futon compression bag consists of a nozzle joint 50 that airtightly connects to the tip of the vacuum cleaner's suction nozzle, and a futon compression bag joint 60 that is molded integrally with the nozzle joint 50 and airtightly connects to the sheet of the futon compression bag. The nozzle joint 50 has a cylindrical cross-section, and the diameter of its outer surface 51 increases as it approaches the futon compression bag joint 60. That is, a recess 52 and a protrusion 53 are continuously formed from the upper end to the lower end, the recess 52 is formed to be convex inward and increase in diameter from near the upper end to the middle, and the protrusion 53 is formed to be convex outward and increase in diameter in the middle, continuing from the recess 52.

[0041] Therefore, the outer diameter of the nozzle joint 50 increases gradually in a geometric progression from near the top to the middle, and decreases gradually in a geometric progression from the middle to the bottom.

[0042] The aforementioned futon compression bag joint 60 is formed in an overall shape roughly like an inverted dish, with a recess 61 formed in a part of it, so that when a suction nozzle with a protrusion is used, the protrusion fits into the recess 61 and does not get in the way.

[0043] Furthermore, the futon compression bag joint 60 is provided with an inner cylinder 62 that is continuous with the nozzle joint 50, and an outer cylinder 63 formed on the outer circumference of the inner cylinder 62, and multiple ribs 64 are formed connecting the inner cylinder 62 and the outer cylinder 63. In addition, a horizontal section 65 is formed in the recess 61 in a direction that is approximately perpendicular (horizontal direction).

[0044] The attachment 1 for the futon compression bag, consisting of the nozzle joint 50 and the futon compression bag joint 60, is integrally formed from an elastic member made of PP resin and has a structure that flexes slightly under external pressure.

[0045] The dimensions of attachment 1 for vacuum storage bags can be set arbitrarily, but as an example, they can be set to the following dimensions.

[0046] The diameter of the outer tip of the nozzle joint 50 is e: 23 mm, the diameter of the lower outer end of the nozzle joint 50 is f: 34.6 mm, the height of the nozzle joint 50 is g: 30 mm, the height of the futon compression bag joint 20 is h: 8.9 mm, and the diameter of the futon compression bag joint is i: 58.4 mm.

[0047] A third embodiment of the attachment for vacuum storage bags according to the present invention will be described with reference to the drawings. Figure 6 is a plan view of the attachment for vacuum storage bags, Figure 7 is a longitudinal cross-sectional view of the attachment for vacuum storage bags, and Figure 7 is a rear view of the attachment for vacuum storage bags.

[0048] The attachment 1 for the futon compression bag of the third embodiment shown in these figures is formed to be the same shape and dimensions as the attachment for the futon compression bag of the second embodiment, except that the futon compression bag joining portion 60 is not disc-shaped, but rather formed in an oval shape with a corresponding part of the periphery slightly recessed inward.
