Actual Inventor(s): Jung-seon Park, lil-won Yang, Hyung-il Jeon Address for Service: PHILLIPS ORMONDE FITZPATRICK Patent and Trade Mark Attorneys 367 Collins Street Melbourne 3000 AUSTRALIA Invention Title: UPRIGHT TYPE VACUUM CLEANER Our Ref: 674631 POF Code: 456924/456925 The following statement is a full description of this invention, including the best method of performing it known to applicant(s): -1- 6006q UPRIGHT TYPE VACUUM CLEANER BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to a vacuum cleaner, and more particularly to an upright type vacuum cleaner comprising a cleaner body and a suction port assembly that are connected to each other and can rotate freely with respect to each other.
2. Description of the Related Art As shown in FIGS. 1 and 2, a general upright type vacuum cleaner 100 comprises a cleaner body 110 and a suction port assembly 130. The suction port assembly 130 has a dust suction hole (not shown) formed in the underside thereof, which is connected with the cleaner body 110 through an air passage.
The cleaner body 110 comprises a rotation shaft portion 115 protruding from two lower opposing sides of the cleaner body 110 and the suction port assembly 130 comprises two oppositely disposed rotation shaft holes 136, each of which is completely formed with a mounting cover 135 being mounted over the rotation shaft hole 136 to form a retainer for one each of the two ends of he rotation shaft portion 115. The cleaner body 110 and the suction port assembly 130 are connected to each other as the rotation shaft portion 115 is inserted into the rotation shaft hole 136, allowing the cleaner body 110 and the suction port assembly 130 to rotate freely with respect to each other. According to the upright type vacuum cleaner 100, a user can perform cleaning operations by varying the angle between the surface to be cleaned and the cleaner body 110 depending on the different cleaning surfaces.
The cleaner body 110 has one or more locking recesses 140 formed in a side thereof. The suction port assembly 130 is provided with a mounting portion 137 and a resilient pedal 150 that is pivotably mounted on the mounting portion 137. The resilient pedal 150 has a locking protrusion 154 protruding from a side thereof. The locking protrusion 154 is sequentially locked in the one or more locking recess 140 when the cleaner body 110 rotates relative to the suction port assembly 130.
The resilient pedal 150 also has a resilient support portion 155 in the shape of a plate that is formed integrally with a lower end of the resilient pedal 150. The resilient pedal 150 is mounted on the mounting portion 137 such that an end of the resilient support portion 155 is supported on an inner wall 137a of the mounting portion 137. Accordingly, the locking protrusion 154 resiliently presses a side surface of the cleaner body 110 and then is sequentially locked in the one or more locking recesses 140 when the cleaner body 110 rotates.
In order for the cleaner body 110 to be released from the locking state in which the locking protrusion 154 is locked in the one or more locking recesses 140 and to once again be free to rotate, a resilient pedal portion 153 is pressed to pivot the resilient pedal 150, releasing the locking protrusion 154 from the one or more locking recesses 140.
The one or more locking recesses 140 preferably include an upright position recess 141 and an inclined position recess 142, which are formed along a portion to which the locking protrusion 154 contacts when the cleaner body 110 rotates. When the cleaner body 110 is in an upright position, the locking protrusion 154 is locked in the upright position recess 141.
Accordingly, the cleaner body 110 does not rotate but is held in the upright portion when the upright type vacuum cleaner 100 is not in use. When the upright type vacuum cleaner 100 is in use, with the cleaner body 110 being rotated at a predetermined angle with respect to a surface to be cleaned, the locking protrusion 154 is locked in one of the inclined position recesses 142. Accordingly, when the vacuum cleaner 100 is lifted up over an obstacle such as a threshold during cleaning, the suction port assembly 130 rotates no more than the predetermined angle with respect to the cleaner body 110.
When in use, the cleaner body 110 of the upright type vacuum cleaner 100 may lie parallel to the surface to be cleaned, as shown in FIG. 3, and accordingly the locking protrusion 154 is pressed to the side surface of the cleaner body 110 such that the resilient support portion 155 remains subject to an external force that deforms the resilient support portion 155 (Figs. 1 and If the upright type vacuum clear 100 is used in this way for a long time, the resilient support portion 155 may become deformed. When that happens, there is a problem of reduced recovery force of the resilient support portion 155.
In addition, as described above, when the cleaner body 110 is used lying in parallel to the surface to be cleaned, the side surface of the cleaner body 110 is pressed by the locking protrusion 154 such that there is a contact resist generated at a contacting portion between the locking protrusion 154 and the cleaner body 110 when the cleaner body 110 rotates.
Accordingly, there is also a problem that the cleaner body does not smoothly rotate due to the contact resist.
SUMMARY OF THE INVENTION The present invention has been developed to solve the above-described problems. Accordingly, it is a first object of the present invention to provide an upright type vacuum cleaner improved in construction so that it becomes capable of preventing deformation of a resilient pedal and reducing any rotation resist of the cleaner body.
According to the present invention in order to achieve the above objects, an upright type vacuum cleaner comprises a suction port assembly, a cleaner body connected to the suction port assembly, the cleaner body and the suction port assembly pivoting freely with respect to each other, at least one locking recess formed in a side of the cleaner body, and a resilient pedal pivotably mounted on the suction port assembly, and having a locking protrusion which is sequentially locked in the at least one locking recess when the cleaner body pivots, and the at least one locking recess comprises a parallel position maintaining recess in which the locking protrusion of the resilient pedal is locked when the cleaner body pivots to a parallel position with respect to a surface to be cleaned.
According to a preferred embodiment of the present invention, the at least one locking recess comprises a upright position recess in which the locking protrusion is locked when the cleaner body is in an upright position with respect to the surface to be cleaned, and one or more inclined position maintaining recesses in which the locking protrusion is locked when the cleaner body pivots at a predetermined angle with respect to the surface to be cleaned.
The resilient pedal preferably comprises a pedal body pivotably mounted on the suction port assembly, the pedal body comprising a locking protrusion protruding from a side toward the cleaner body and a pedal portion being subject to an external force to release the locking protrusion from the one or more locking recesses and a resilient support portion for resiliently pressing a side of the pedal body to rotate the pedal body in a direction where the locking protrusion presses the cleaner body.
The resilient support portion comprises a plate element integrally protruding from a lower side of the pedal body, the resilient member having a bending portion to be supported by an inner wall of the suction port assembly.
One or more of the locking recesses may have a slanted surface such that the locking protrusion is easily released from the locking recess when the cleaner body rotates in the upright position.
BRIEF DESCRIPTION OF THE DRAWINGS The above objects and characteristic of the present invention will be more apparent by describing a preferred embodiment of the present invention in greater detail with reference to the accompanying drawings, in which: FIG. 1 is an exploded perspective view showing a conventional upright type vacuum cleaner; FIG. 2 is an elevational rear view showing a detail of the upright type vacuum cleaner of FIG. 1 in an assembled state; FIG. 3 is an elevational side view showing the upright type vacuum cleaner of FIG. 1 in use; FIG. 4 is an exploded perspective view showing an upright type vacuum cleaner according to a preferred embodiment of the present invention; and FIG. 5 is a perspective view showing a main part of the upright type vacuum cleaner of FIG. 4 showing the operation of the upright type vacuum cleaner according to the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, a preferred embodiment of the present invention will be described in greater detail with reference to the accompanying drawings. With respect to those components having constructions and functions similar to those of the conventional upright type vacuum cleaner described with reference to FIGS. 1 through 3, identical reference numerals are assigned. Therefore, a detailed description of like numbered parts will be omitted.
Referring now to FIGS. 4 and 5, an upright type vacuum cleaner 200 according to the present invention includes a cleaner body 110 and a suction port assembly 130 rotatably connected to the cleaner body 110. A driving shaft 116 rotates in association with the rotation of a suction motor (not shown) which is built within the cleaner body 110, and the reference numeral 138 refers to a connection pipe for connecting a dirt suction hole (not shown) to the cleaner body 110 to allow air to flow therethrough.
The cleaner body 110 has a plurality of locking recesses 240 formed in proximity to the suction port assembly 130. A resilient pedal 150, having a locking protrusion 154, is pivotably mounted on the suction port assembly 130.
Accordingly, when the cleaner body 110 rotates with respect to the suction port assembly 130, the locking protrusion 154 is resiliently locked in one of the locking recesses 240, thereby sequentially restricting the cleaner body 110 from rotating.
The resilient pedal 150 includes a pedal body 151 and a resilient support portion 155. The pedal body 151 includes the locking protrusion 154 protruding from a side thereof, a rotation shaft 152 formed through a center thereof, and a pedal portion 153 formed on an upper portion thereof. The pedal body 151 is pivotably mounted on the suction port assembly 130 in such a manner that the rotation shaft 151 is rotatably connected to a mounting portion 137 of the suction port assembly 130. At this point, the pedal portion 153 is exposed in an upward direction from the suction port assembly 130. Accordingly, a user presses a top of the pedal portion 153 to pivot the pedal body 150 during use of the upright type vacuum cleaner 200.
The resilient support portion 155 resiliently urges the pedal body 151 to pivot the pedal body 151 in a predetermined direction. In this embodiment, the resilient pedal 150 is provided with a resilient support portion comprising a plate member 155, which protrudes from a lower end of the pedal body 151. The plate member 155 is integrally formed with the pedal body 151 and has a bending portion formed at a center thereof.
As described above with reference to FIG. 2, the pedal body 151 is mounted on the mounting portion 137 such that an end of the plate member 155 is supported on an inner wall 137a (FIG. 2) of the mounting portion 137. When the pedal portion 153 is subject to an external force, the pedal body 151 pivots and thus the plate member 155 is deformed. As a result of its resilient characteristics, the plate member 155 is subject to a recovering force. Being released from the external force, the plate member 155 has a tendency to recover its original shape due to the recovering force, and accordingly, the pedal body 151 is automatically returned to its initial position.
The initial position of the pedal body 151 is a position where the locking protrusion 154 resiliently presses a side of the cleaner body 110.
Meanwhile, the resilient pedal 150 is not limited to the described preferred embodiment. That is, various changes and modifications can be made if the resilient pedal 150 includes the pedal body 151 pivotably mounted on the suction port assembly 130 to pivot by a pressure of a user, and the resilient support portion 155 for resiliently pressing the pedal body 151.
A lower side of the cleaner body 110, which contacts with the locking protrusion 154 of the resilient pedal 150 when the cleaner body 110 rotates, has a partially concave configuration to form the plurality of the locking recesses 240. The locking recesses 240 include an upright position recess 241, an inclined position recess 242, and a parallel position recess 243, as shown in FIG. 4.
The upright position recess 241, on which the locking protrusion 154 is locked, allows the cleaner body 110 to maintain its upright position with respect to a surface to be cleaned. Accordingly, when the upright type vacuum cleaner 200 is not in use, generally with the cleaner body 110 being in the upright position with respect to the surface to be cleaned, the locking protrusion 154 is locked in the upright position recess 241 such that the cleaner body 110 is prevented from rotating regardless of an external force or of its own weight.
The inclined position recess 242 restricts the cleaner body 110 from rotating beyond a predetermined angle between the cleaner body 110 and the suction port assembly 130. That is, when the cleaner body 110 rotates at the predetermined angle with respect to the suction port assembly 130, the locking protrusion 154 is locked in the inclined position recess 242, thereby preventing the cleaner body 110 from further rotating beyond the predetermined angle. Accordingly, when there is a small obstacle such as a threshold ahead, the upright type vacuum cleaner 200 is easily lifted to avoid the obstacle during cleaning. The plural inclined position recesses 242 can be provided, if necessary.
The parallel position recess 243, on which the locking protrusion 154 may be locked, allows the cleaner body 110 to maintain its parallel position with respect to the surface to be cleaned. When the cleaner body 110 lies in a position parallel to the surface to be cleaned, the plate member 155 is in relaxed state. Accordingly, even when the upright type vacuum cleaner 200 is used with the cleaner body 110 lying in a position parallel to the surface to be cleaned for a long time, permanent damage to plate member 155 is prevented.
The parallel position recess 243 has a slanted surface 243a formed on a side thereof. When the cleaner body 110 is rotated into an upright position, due to the presence of the slanted surface 243a, the locking protrusion 154 is easily released from the parallel recess 243. Accordingly, when the locking protrusion 154 presses a side surface of the cleaner body 110 it is moved along the slanted surface 243a of the parallel position maintaining recess 243, since the plate element 155 is in relaxed state to some extent, the load on the plate member 155 is decreased. Therefore, there is an effect of decreasing an operation resist, which is generated when the locking protrusion 154 resiliently presses the side surface of the cleaner body 110. It is preferred that the inclined position recess 242 has a slanted surface 242a to decrease the operation resist, which is generated when cleaner body 110 rotates.
According in the upright type vacuum cleaner 200 constructed as described above, the locking protrusion 154 is locked in the locking recesses 240 such that the cleaner body 110 is prevented from rotating further toward the cleaning surface. For a further rotation of the cleaner body 110 toward the cleaning surface, the locking protrusion 154 has to be released from the locking recesses 240. In order for the locking protrusion 154 to be released from the locking recesses 240, a user must press the pedal portion 153 to pivot the resilient pedal 150. After the locking protrusion 154 is released from the locking recesses so that the cleaner body 110 rotates by pressing of the pedal portion 153, the resilient pedal 150 automatically pivots due to a resilient force of the resilient support portion 155 and allows the locking protrusion 154 to contact with the cleaner body 110.
According to the present invention as described above, the resilient support portion 155 is in relaxed state even when the cleaner body 110 is in a parallel position with respect to the surface to be cleaned, since the locking protrusion 154 is locked in the parallel position recess 243 which is formed on the side surface of the cleaner body 110.
Accordingly, the resilient support portion 155 is in relaxed state even when the cleaner body 110 is in parallel to the surface to be cleaned for a long time, and as a result, the resilient support portion 155 is prevented from being deformed permanently.
Also, when the cleaner body 110 rotates and the locking protrusion 154 moves in proximity to the parallel position recess 243, the resilient support portion 155 is subject to a lesser load due to the presence of the slanted surface 243a formed on the parallel position recess 243. Therefore, there is an effect of decreasing the operation resist of the rotating operation of the cleaner body 110.
Although preferred embodiments of the present invention have been described, it is understood that the present invention should not be limited to these preferred embodiments but various changes and modifications can be made by one skilled in the art within the spirit and scope of the present invention as hereinafter claimed.
