Definitions

  • the present invention relates to improvements in suction members to be attached to vacuum cleaners for use in cleaning, for example, bedclothes and curtains.
  • suction members of this type there are known suction members of the type having a rotatable member with a multiplicity of perforations rotatably mounted on a cylindrical suction member body, as disclosed in Japanese Unexamined Patent Publication No. 158068/1979 (92(3)D101.9) and Japanese Unexamined Utility Model Publication No. 79761/1977 (92(3)D101.9). These suction members are adapted to draw in dust from an air inlet defined in a lower portion of the outer surface of the suction member body through the rotatable member and thereby to collect dust into a vacuum cleaner through a pipe connected to a side of the suction member body.
  • the suction member disclosed in Japanese Utility Model Publication No. 79761/1977 (92(3)D101.9) comprises a suction member body defining air inlets in a lower portion of the outer surface thereof, a suction member cover fitted around and bonded to a lateral side of the suction member body with a pipe to be connected to a vacuum cleaner being force fitted thereinto, and a rotatable member with a multiplicity of perforations rotatably covering the outer surface of the suction member body, the rotatable member being supported at the outer surface of a pipe support portion of the suction member cover so as not drop out.
  • the rotatable member of the suction member disclosed in Japanese Unexamined Patent Publication No. 158068/1979 comprises an annular one-piece mesh covering the entire outer surface of the suction member body. This impedes easy changes of the moving direction of the suction member body, resulting in poor cleaning operability.
  • the rotatable member is of a simple mesh structure, hair and waste thread are likely to be caught by the rotatable member and, hence, a difficulty exists in cleaning a surface of an object.
  • the rotatable member since the rotatable member abuts the entire outer surface of the suction member body, the rotatable member has an increased friction resistance against the suction member body and hence suffers poor mobility and poor cleaning operability.
  • the rotatable member comprises the annular one-piece mesh covering the entire outer surface of the cylindrical suction member body and an air inlet is defined by notching a portion of the cylindrical body of the suction member body. For this reason, the suction member body is likely to sink into bedclothes or curtains, thus rendering the mobility thereof poor.
  • the both ends of the rotatable member are threaded, and in correspondence therewith the outer periphery of each disc provided to the lateral side of the suction member body is required to be threaded, resulting in a complicated structure.
  • connection pipe of the suction member of Japanese Unexamined Patent Publication No. 158068/1979 is fixedly secured to the lateral side of the suction member body. This causes the angle of the suction member body with respect to a surface for cleaning to vary in the push-pull operation of the suction member body thereby varying the distance between the air inlet and the surface for cleaning and the angle made therebetween. This in turn causes the suction force exerted on the surface for cleaning to vary, thus resulting in nonuniform cleaning.
  • the suction member is of a structure such that a connection pipe is force fitted into the suction member cover, there might be a case where the connection pipe is not securely held by the suction member cover because of errors in the production of the connection pipe and suction member cover and, hence, the suction member cover frequently comes off the connection pipe, thus degrading the cleaning operability.
  • the overall rotatable member is formed as having an even diameter, the rotatable member will be pressed against the suction member body and any perforation of the rotatable member is caught by the air inlet, with the result that rotation of the rotatable member is impeded unfavorably to degrade the mobility of the suction member, thus raising a problem of degraded cleaning operability.
  • an object of the present invention to provide a suction member for use with a vacuum cleaner which exhibits improved cleaning operability and cleaning performance.
  • Another object of the present invention is to provide a suction member having a rotatable member and suction member body of improved maintainability.
  • a suction member for rise with a vacuum cleaner comprising a suction member body having substantially centrally thereof a connection pipe to be connected to the vacuum cleaner, air inlet defined in lower portions of the outer surface of the suction member body on both sides of the suction member body, and rotatable members defining a multiplicity of small perforations and each rotatably provided around the outer surface of the suction member body on either side of the suction member body.
  • a suction member for use with a vacuum cleaner comprising a suction member body having substantially centrally thereof a connection pipe to be connected to the vacuum cleaner, an air inlet defined over substantially entire lower portion of the outer surface of the suction member body, and rotatable members defining a multiplicity of small perforations and each rotatably provided around the outer surface of the suction member body on either side of the suction member body.

  • Each bearing member 215 has a support portion 218 formed centrally thereof to support a shaft portion 220 (to be described later) of each rotatable member 219 for rotation.
  • the support portion 218 is made relatively long along the longitudinal axis of the tubular member 202 to prolong the length of the shaft portion 220 received in the support portion 218, whereby the rotatable member 219 is supported thereon with minimized irregular rotation.
  • the rotatable members 219 in cylindrical form define a multiplicity of small perforations and cover the outer surface of the tubular member 202 on both sides thereof and are formed of a synthetic resin, such as a polypropylene resin, which is different from the materials (for example, ABS resin) of the tubular member 202, cover 210, bearing members 215 and support members 224 to be described later.
  • the shaft portion formed at one end of each rotatable member 219 is rotatably supported on the outer periphery of the support portion 218 of each bearing member 215.
  • the other end of the rotatable member 219 approximates each lateral side of a bulged portion 221 formed as circumferentially outwardly bulging in central portions of the tubular member 202 and cover 210 so as to avoid the entry of dust or the like from the space between the aforesaid other end of the rotatable member 219 and the corresponding lateral side of the bulged portion 221 into the space between each rotatable member 219 and the tubular member 202. In this way the rotatable members 219 are prevented from faulty rotation or from generating abnormal noise due to friction.
  • the rotatable members 219 each define a plurality of elongated openings 222 of which the longitudinal axes extend substantially parallel to that of the tubular member 202 and of which the circumferential pitch is made larger than that of the air inlets 206 whereby the openings 222 have a reduced hole area in total and, hence, a decrease in the strength of the rotatable members 219 is alleviated.
  • a pair of annular projections 223 are formed integrally with each rotatable member 219 at the opposite ends of the outer periphery thereof and located adjacent and correspondingly to each first convex 207 and each annular convex comprising second convex 208 and fourth convex 214, each of the annular projections 223 being larger in diameter than the bulged portion 221 of the tubular member 202.
  • the suction member thus arranged is connected to a vacuum cleaner at the connection pipe 204 through a suction hose and an extension pipe and is then used in cleaning a surface for cleaning such as bedclothes or curtains by actuating the vacuum cleaner and push-pull operating the suction member.
  • the connection pipe 204 is pivotable within a predetermined range, specifically within the range of about 60° in this embodiment, a cleaning operation can be achieved with the connection pipe 204 even slanted, so that the suction member offers improved cleaning operability.
  • the suction member body 201 will never be inverted, there is no possibility of erroneous use of the suction member such as cleaning with the air inlets 205 oriented upward.
  • the suction member When the suction member is push-pull operated on the surface for cleaning, the rotatable members 219 rotate thereby moving the suction member body 201. Since the suction member body 201 has the connection pipe 204 in a central portion thereof and supports the rotatable members 219 for rotation, the suction member is improved in balance and mobility and hence enjoys improved cleaning operability.
  • each rotatable member 219 When a relatively hard surface for cleaning is to be cleaned, only the projections formed on the opposite ends of each rotatable member 219 are brought into contact with the surface for cleaning. Accordingly, there is no possibility that the rotatable members 219 are radially inwardly deformed and contact the suction member body 201 thereby increasing the frictional resistance therebetween, or that the peripheral edge of each small perforation or each opening 222 is caught by the peripheral edge of any air inlets 206 of the suction member body 201 to cause faulty rotation of the rotatable members 219.
  • the annular projections 223 of the rotatable members 219 are made larger in outer diameter than the bulged portion 221 of the suction member body 201, with the result that the friction between the bulged portion 221 of the suction member body 201 and the surface for cleaning is made small thereby keeping the improved mobility of the suction member. Furthermore, since the rotatable members 219 are supported by the first, second, third and fourth convexes 207, 208, 209 and 214, there is a reduced frictional resistance between the rotatable members 219 and the suction member body 201 and, hence, the rotatable members 219 rotate with ease thereby assuring the suction member of improved mobility and cleaning operability.
  • each rotatable member 219 intends to deform toward the suction member body 201 when they are pressed against the surface for cleaning
  • the provision of the first and fourth convexes 207 and 214 abutting or approximating the inner surface of each rotatable member 219 at positions substantially opposing the projections 223 of the suction member body 201 prevents the inner surface of each rotatable member 219 from contacting the outer surface of the suction member body 201, so that the rotatability of each rotatable member 219 is kept satisfactory.
  • Dust adhering to the surface for cleaning is drawn into the suction member body 201 through a multiplicity of perforations and a plurality of openings 222 of the rotatable members 219 and collected into the vacuum cleaner through the connection pipe 204, extension pipe and suction hose.
  • each rotatable member 219 defines the openings for communication with the air inlets 206 of the suction member body 201, relatively large dust including hair and waste thread can assuredly collected at positions where the openings 222 come to coincide with the air inlets 206 of the suction member body 201 as the rotatable members 219 rotate.
  • the suction force of the vacuum cleaner causes the surface for cleaning to be attracted by a lower portion of the rotatable members 219, namely the portion opposite to the air inlets 206 of the suction member body 201.
  • the rotatable members 219 are kept spaced apart from the outer surface of the suction member body 201 by the first, second, third and fourth convexes 207, 208, 209 and 214, there is no possibility that the air inlets 206 are covered with the surface for cleaning and, hence, the dust collectability of the suction member can be maintained.
  • the cover 210 of the embodiment shown in Figs. 15 to 21 is formed of a synthetic resin such as ABS resin. Since the cover 210 contacts the surface for cleaning and might be degraded in mobility due to the frictional resistance therebeween, it is desired that the cover 210 be formed of a material of low frictional resistance such as a polyacetal resin or an olefin resin.
  • the pressing force of the suction member against the surface for cleaning generated by the user push-pull operating the suction member during cleaning is the strongest in the vicinity of the connection pipe 204 and, therefore, the contacting force between the fourth convexes 214 and the rotatable members 219 becomes the strongest. Accordingly, the fourth convexes 214 are likely to be abraded during long time use.
  • the cover 210 by forming the cover 210 with the material of low frictional resistance, the frictional resistance between the fourth convexes 214 of the cover 210 and the rotatable members 219 are reduced thereby improving the mobility of the suction member.
  • first, second, third and fourth annular convexes 207, 208, 209 and 214 are formed on the outer surface of the suction member body 201 as approximating or abuttingly supporting the rotatable members 219 to reduce the friction resistance of the rotatable members 219 against rotation
  • convexes 227 might be formed only on lower surfaces of the suction member body 201 as shown in Fig. 22. With this arrangement, it is possible to assuredly provide a space between the rotatable members 219 and the suction member body 201 thereby keeping the dust collectability of the suction member satisfactory, and to reduce the contact area between the rotatable members 219 and the convexes thereby decreasing the frictional resistance of the rotatable members 219 against rotation.
