Description
- 1. Field of the Invention
- The present invention relates to luggage and more particularly, to a luggage inflatable structure which has a piston mounted on the bottom side of the pull rod of the luggage and movable up and down with the pull rod in a sleeve inside the luggage to pump air into a air bag so that storage items are held firmly in position when the air bag is inflated, avoiding storage item damage or noises during carrying or delivery of the luggage.
- 2. Description of the Related Art
- When carrying or delivering a luggage, the items stored in the luggage may be forced to hit one against another, causing storage item damage or producing noises. Air bags or elastic cushion pads may be set in a luggage to hold down storage items in place. However, when the volume of the storage items is changed following traveling, the air bags or elastic cushion pads may be unable to hold down the storage items in place. In this case, storage item damage or noises may occur.
- Further, US 2004/0035185 teaches the use of an inflation connector for the connection of an air pump to pump air into the luggage.
- The present invention has been accomplished under the circumstances in view.
- It is therefore the main object of the present invention to provide a luggage inflatable structure, which allows inflation of an air bag to any status subject to the amount of storage items in the luggage, enabling the storage items to be firmly held in place between the peripheral wall of the housing of the luggage and a bottom lining when the user is carrying the luggage or when the luggage is being delivered, avoiding storage item damage or noises.
- It is another object of the present invention to provide a luggage inflatable structure, which has a simple structure, requires less installation space, and fully utilizes the internal space of the luggage.
-
FIG. 1 is a schematic sectional view of a luggage having an inflatable structure in accordance with the present invention. -
FIG. 2 is a schematic section view of the present invention, illustrating storage items accommodated in the luggage and the air bag flattened. -
FIG. 3 corresponds toFIG. 2 , illustrating the air bag inflated. - Referring to
FIGS. 1˜3 , an inflatable structure of a luggage in accordance with the present invention is shown comprising: - at least one
sleeve 1 fixedly mounted between an upper locatingblock 52 and a lower locatingblock 53 at one side in ahousing 51 of aluggage 5 with fasteningmembers 56;57 and defining abottom air inlet 14 that is connected to anair intake pipe 11 in theluggage 5 and anaxial piston hole 10 that receives apull rod 2, where the upper locatingblock 52 has a locatinggroove 521 for the positioning of the top end of thesleeve 1; the lower locatingblock 53 has a locatinghole 531 for the positioning of the bottom end of thesleeve 1 and a fasteningmember 532 mounted in the locatinghole 531 to affix the bottom end of thesleeve 1; - at least one
pull rod 2 that has itsbottom end 22 inserted theaxial piston hole 10 of thesleeve 1 and fixedly connected with apiston 20 and its top end provided with agrip 21 and is movable up and down in theaxial piston hole 10 of thesleeve 1 to pump air through theair intake pipe 11 into anair bag 3; - an
air bag 3 mounted in one side inside thehousing 51 of theluggage 5 between abottom lining 54 and thesleeve 1 and having anair pipe 35 connected to theair intake pipe 11 for guiding pumped air from thesleeve 1 into theair bag 3 for enabling theair bag 3 to be inflated upon reciprocating motion of thepiston 20 with thepull rod 2 in theaxial piston hole 10 of thesleeve 1, wherein thebottom lining 54 can be a rigid sheet member, or a fabric, synthetic leather or flexible sheet member connected to thehousing 51 of theluggage 5; and - an air-
valve switch 4, which comprises afirst air port 41 connected to theair intake pipe 11, asecond air port 42 connected to theair pipe 35 of theair bag 3, anexhaust pipe 43 connected to a throughhole 511 on the peripheral wall of thehousing 51 of theluggage 5 and anoperation panel 44 with an air intake control key (not shown) and an exhaust control key (not shown), wherein when the air intake control key is switched on, thefirst air port 41 and thesecond air port 42 are opened and theexhaust pipe 43 is closed for enabling pumped air to flow through the air-valve switch 4 and theair pipe 35 into theair bag 3; when the exhaust control key is switched on, thefirst air port 41 is closed, thesecond air port 42 and theexhaust pipe 43 are opened, for enabling air to be exhausted out of theair bag 3 through theair pipe 35, thesecond air port 42 and theexhaust pipe 43. - Further, the top end of the
sleeve 1 is covered with acap 12 that has a throughhole 121 for the passing of thebottom end 22 of thepull rod 2. - Further, an one-
way valve 111 is installed in theair intake pipe 11 of thesleeve 1 for allowing air to flow in direction from thesleeve 1 toward theair pipe 35 of theair bag 3 and prohibiting backward flowing of air from theair pipe 35 toward the inside of thesleeve 1. - Further, the air-
valve switch 4 is mounted in aswitch hole 512 on the peripheral wall of thehousing 51 of theluggage 5, keepingoperation panel 44 on the outside of theluggage 5 for operation by a user. - Further, the
air bag 3 is a hollow inflatable container made of a flexible rubber material having a high deformation rate. - As stated above, the
piston 20 is fixedly connected to the bottom end of thepull rod 2 and movable up and down with thepull rod 2 in theaxial piston hole 10 of thesleeve 1 to pump air through theair intake pipe 11 into theair bag 3. When theair bag 3 is inflated, it imparts a pressure to thebottom lining 54 against thestorage items 6 in thehousing 51 of the luggage 5 (seeFIG. 3 ), holding thestorage items 6 firmly in place against displacement. Therefore, when carrying or delivering theluggage 5, thestorage items 6 are firmly held in position and will not hit against one another, avoiding storage item damage or noises. After each use, the internal air of theair bag 3 can be exhausted through theexhaust pipe 43 of the air valve switch 4 (seeFIG. 2 ). - In conclusion, the invention has advantages as follows:
-
- 1. All storage items, no matter how much the amount, can be held firmly in place between the peripheral wall of the
housing 51 of theluggage 5 and thebottom lining 54 when theair bag 3 is inflated when the user is carrying theluggage 5 or when theluggage 5 is being delivered, avoiding storage item damage or noises. - 2. Subject to the arrangement of the
piston 20 at the bottom end of thepull rod 2, theair intake pipe 11 at the bottom side of thesleeve 1 and the air-valve switch 4 in between theair bag 3 and theair intake pipe 11, the inflatable structure of the present invention has a simple structure, requires less installation space, and fully utilizes the internal space of the luggage. - 3. The operation of the inflatable structure is easy. The user can be inflated or flattened conveniently when desired. It is not necessary to use an external air pump when wishing to inflate the air bag.
- 1. All storage items, no matter how much the amount, can be held firmly in place between the peripheral wall of the
