Abstract
Description
- This application claims priority to copending Korean Patent Application No. 2003-72874 filed in the Korean Intellectual Property Office on October 20, 2003, the entire contents of which are incorporated herein by reference.
- This application is related to the co-pending application entitled, "Bendable Nozzle For Vacuum Cleaner", (Korean Application 10-2003-72873, filed October 20, 2003) which disclosure is commonly owned by the same assignee as the present application and is entirely incorporated herein by reference.
- The present invention relates to a vacuum cleaner, and more particularly, to a bendable extension pipe of a vacuum cleaner which enables the operator of the cleaner to clean the small places underneath furniture such as a bed and a couch with convenience.
- Generally, a vacuum cleaner draws in dust from a cleaning surface along with ambient air using a suction force which is generated by a suction motor provided inside a cleaner body. In order to allow drawn in air and dust to pass into the cleaner body, a fluid passage is sealingly formed connecting the cleaner body and the suction brush while contacting on the cleaning surface.
- Various types of fluid passages are available. For example, a canister vacuum cleaner may include a flexible hose connecting the cleaner body with an operation handle, and an extension pipe connecting the operation handle with the suction brush. Generally, the extension pipe is formed in a telescopic manner, or formed from a plurality of assembly pipe parts to enable adjustment in length as necessary.
- In the vacuum cleaner as described above, the extension pipe and the suction brush are usually at a fixed angle and as a result, it is inconvenient for an operator to clean lower places such as places underneath the bed or couch. That is, the operator has to lower his/her body, keep the suction brush in contact with the cleaning surface and turn the extension pipe to clean the underside places. Even with the extension pipe and the suction brush disposed at an adjustable angle, however, there still exists an inconvenience because the operator has to bend his body to put the suction brush underneath the furniture.
- Thus, a heretofore unaddressed need exists in the industry to address the aforementioned deficiencies and inadequacies.
- The present invention has been developed in order to solve the above drawbacks and other problems associated with the conventional arrangement. An object of the present invention is to provide a bendable extension pipe for a vacuum cleaner which has an improved structure to enable an operator to perform a cleaning operation without having to bend or lower his/her body, but bending the extension pipe through a simple manipulation of a few buttons.
- The above aspects and/or other features of the present invention can be substantially achieved by providing a bendable extension pipe for a vacuum cleaner with a body bent by a button manipulation, the bendable extension pipe forming a sealed fluid passage between a vacuum cleaner body and a suction brush. The bendable extension pipe includes a first extension pipe, a second extension pipe rotatably connected with the first extension pipe, a locking button elastically disposed on the first extension pipe, to restrict rotation of the first and the second extension pipes, and a sealing cover for preventing the locking button from moving out of joint from the first and second extension pipes and sealing the first and the second extension pipes.
- According to a preferred embodiment, the locking button is formed on a seating protrusion which is protruded from a side of an axis of a rotation of a joint which movably connects the first extension pipe and the second extension pipe. The locking button includes at least one interfering rib protruding along the outer circumference and a restriction projection for restricting the rotation of the first and the second extension pipes. The seating protrusion includes at least one guide projection formed on the outer circumference and a sliding groove formed in the locking button to coincide with the guide projection. With a push and release of the locking button, the sliding groove is guided by the guiding projection to prevent a rotation of the locking button. An elastic member is disposed between the locking button and the seating protrusion. With the push of the locking button, the elastic member exerts a recovery force in the direction of a release from the locking button.
- The second extension pipe includes a slot plate with a sliding slot for a sliding engagement with the seating projection. The sliding slot includes one open end. A locking part is formed in a position corresponding to a restriction projection to selectively lock the restriction projection in accordance with a displacement of the restriction projection in an axial direction. The locking part is separated from the slot plate by a distance equal to, or greater than the thickness of the restriction projection.
- The sealing cover includes a first cover with a button hole corresponding in size with the outer circumference of the locking button, and a second cover engaged with the first cover and sealing connecting parts between the first and the second extension pipes.
- Other systems, methods, features, and advantages of the present invention will be or become apparent to one with skill in the art upon examination of the following drawings and detailed description. It is intended that all such additional systems, methods, features, and advantages be included within this description, be within the scope of the present invention, and be protected by the accompanying claims.
- The above aspects and other features of the present invention will become more apparent by describing in detail certain embodiments thereof with reference to the attached drawings. The components in the drawings are not necessarily to scale, emphasis instead of being placed upon clearly illustrating the principles of the present invention. Moreover, in the drawings, like reference numerals designate corresponding parts throughout several views.

- FIG. 2 is a drawing of an exploded perspective view of a bendable extension pipe according to an embodiment of the present invention;
- FIG. 3 is a drawing of a perspective view illustrating a bendable extension pipe according to an embodiment of the present invention before the bending, with a sealing cover being omitted; and
- FIG. 4 is a drawing of a perspective view illustrating a bendable extension pipe according to an embodiment of the present invention after the bending, with a sealing cover omitted.
- Certain embodiments of the present invention will be described in greater detail with reference to the accompanying drawings.
- FIG. 1 is a perspective view illustrating a
bendable extension pipe 100 for a vacuum cleaner according to an embodiment of the present invention. Referring to FIG. 1, thebendable extension pipe 100 includes first andsecond extension pipes locking button 130. Asealing cover 140 prevents a suction loss of the connecting parts and also prevents thelocking button 130 from moving out of joint from the first and second extension pipes in the axial direction. - Referring to FIG. 2, the
first extension pipe 110 includes a cylinder joint J1 which has an opening (not shown) at a side facing thesecond extension pipe 120, and approximately at the center of the cylinder joint J1, aseating protrusion 111 is formed overlapping with the rotational axis. Thelocking button 130 is movably disposed on theseating protrusion 111 for the push and release movement, and in one example, theseating protrusion 111 may be inserted in thelocking button 130 with the intervention of an elastic member S therebetween. As shown in FIG. 2, at least oneguide projection 111a and slidinggroove 130a are formed on each of theseating protrusion 111 and thelocking button 130 in a complementary manner. Accordingly, when thelocking button 130 is pushed or released by theguide projection 111a which is engaged in thesliding groove 130a in the outer circumference, thelocking button 130 is guided such that thelocking button 130 turns in association with the turning of thefirst extension pipe 110 to the same rotational angle. - An interfering
rib 131 is formed on an outer circumference of thelocking button 130 to prevent thelocking button 130 from moving out in the axial direction, and arestriction projection 132 is formed also on the outer circumference of thelocking bottom 130 to restrict the rotational angle of the first and thesecond extension pipes rib 131 with a larger diameter than thelocking button 130 may be formed in the circumferential direction as shown in FIG. 2, to prevent thelocking button 130, which is exposed outside of thesealing cover 140, from moving out in the axial direction. In a preferred embodiment, the interferingrib 131 may be arranged symmetrically to be supported evenly on thesealing cover 140 and not to be tilted. - At least one
restriction projection 132 may be formed in a circumferential direction, each on appropriate locations which do not coincide with the interferingrib 131. Therestriction projection 132 may be formed with a smaller height than the interferingrib 131, and additionally, therestriction projection 132 may be tapered on a predetermined side to require less force of an operator in bending the first and thesecond extension pipes - The
second extension pipe 120 includes a cylinder joint receiving portion J2, which has a complementary shape as the cylinder joint J1 of thefirst extension pipe 110 for a turnable engagement. The cylinder joint receiving portion J2 includes a slot plate 121 which has asliding slot 121a for a sliding engagement with theseating projection 111 to a proximity of the center of thesecond extension pipe 120, and alocking part 122 which selectively contacts with therestriction projection 132 to restrict a rotation of the first and thesecond extension pipes - The slot plate 121 includes a circular plate. The slot plate 121 has the same diameter as that of the cylinder joint J1 such that the inner circumference of the cylinder joint receiving portion J2 meets the outer circumference of the cylinder joint J1 in a tight contact. The
sliding slot 121a includes the width that corresponds to the diameter of theseating projection 111 so that the center of theseating projection 111 can coincide with the center part of the slot plate 121. A closed end of thefirst extension pipe 110 may have a circular arc as shown in FIG. 2 to enable thefirst extension pipe 110 to rotate on theseating projection 111. - The
locking part 122 restricts the rotation of the first and thesecond extension pipes restriction projection 132. In the preferred embodiment, thelocking part 122 may be formed at a predetermined distance from the slot plate 121 and the predetermined distance is larger than the thickness of therestriction projection 132. When the operator pushes thelocking bottom 130, therestriction projection 132 is displaced in the axial direction, and moved out of contact with thelocking part 122 to a position in which therestriction projection 132 can be passed through a space between thelocking part 122 and the slot plate 121. - The sealing
cover 140 prevents a suction loss from occurring between the cylinder joint J1 and the cylinder joint receiving portion J2, and between the first and thesecond extension pipes cover 140 may have first andsecond covers locking button 130 from moving out in the axial direction. Thefirst cover 141 includes abutton hole 141a to expose thelocking button 130. Thebutton hole 141a includes a size that corresponds to the outer circumference of thelocking button 130. In the preferred embodiment, thebutton hole 141 a may have a size equal to, or greater than the outer circumference of thelocking button 130, and smaller than the outer circumference of thelocking button 130 with the interferingrib 131, such that the interferingrib 131 is supposedly on an inner circumference of thefirst cover 141 to prevent thelocking button 130 from moving out in the axial direction. - The operation of the bendable extension pipe for a vacuum cleaner according to one exemplary embodiment of the present invention will be described with reference to FIGS. 3 and 4.
- FIG. 3 shows the first and the
second extension pipes cover 140 has been omitted from FIG. 3. In normal operation, i.e., when the vacuum cleaner is cleaning places such as floor, the first andsecond extension pipes restriction projection 132 contacts oneend 122a of the lockingpart 122 to prevent the first andsecond extension pipes rib 131 contacts theother end 122b of the lockingpart 122 to support and prevent the first andsecond extension pipes - When the operator wants to clean places such as underneath a bed or a couch, the operator presses the
locking button 130, and accordingly, therestriction projection 132 is moved out of the lockingpart 122 to a position in which therestriction projection 132 can be passed through the space between the lockingpart 122 and the slot plate 121. When the operator bends the first or thesecond extension pipes locking button 130, therestriction projection 132 contacts the inner circumference of the space defined between the lockingpart 122 and the slot plate 121 and becomes rotatable. - In another embodiment of the present invention, the first and the
second extension pipes second extension pipes locking button 130, and, if the imaginary line connecting theend 122a in contact with the lockingpart 122 is at an angle of 45° with respect to the first andsecond extension pipes other end 122b of the lockingpart 122 with an interior angle of 45°. - When the
restriction projection 132 rotates by 45°, the tapered inclining end slides along the lockingpart 122 and urges thelocking button 130 toward the release direction in which the recovery force of the elastic member S is exerted. As a result, thelocking button 130 returns to the initial state, i.e., to the state before the operator presses thelocking button 130 to bend thebendable extension pipe 100. The operator manipulates theextension pipe 100 in the reverse order to return the first andsecond extension pipes operation pipe 100 by pressing on thelocking button 130, the recovery force of the elastic member S returns thelocking button 130 to the initial position. - With the
bendable extension pipe 100 as described above in a few embodiments of the present invention, operator convenience increases because the operator is not required to bend or lower his/her body to clean underneath furniture such as a bed and couch, but only requires the operator to make a simple button manipulation. - The foregoing embodiment and advantages are merely exemplary and are not to be construed as limiting the present invention. The present teaching can be readily applied to other types of apparatuses. Also, the description of the embodiments of the present invention is intended to be illustrative, and not to limit the scope of the claims, and many alternatives, modifications, and variations will be apparent to those skilled in the art.
