Description
UPRIGHT TYPE VACUUM CLEANER
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 S which are connected to each other and which can rotate or pivot freely with respect to each other.
As shown in Figures 1 and 2, a known upright type vacuum cleaner 100 comprises a cleaner body 110 and a suction port assembly 130. The suction port assembly 130 has a 10 dust suction hole (not shown) formed in the underside thereof, which communicates with the cleaner body 110 through an air passage. The cleaner body 110 comprises a shaft portion 115, having shaft ends protruding from two lower lateral sides of the cleaner body 110. The suction port assembly 130 comprises two opposing shaft holes 136 for receiving the shaft ends, each hole being formed with a mounting cover 135 15 arranged over each shaft hole 136 so as to form a retainer for each respective shaft end of the rotation shaft portion 115. The cleaner body 1 10 and the suction port assembly 130 are connected to each other by means of the shaft ends of the rotation shaft portion 115 which are engaged into the shaft holes 136. In this way, the cleaner body 1 10 and the suction port assembly 130 can rotate freely with respect to each other. A user can 20 thus perform a required cleaning operation by varying the angle between the surface to be cleaned and the cleaner body 110. This variation may be required to suit different cleaning surfaces.
The cleaner body 110 has one or more locking recesses 140 formed in a side portion 25 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 extending from a side part thereof. The locking protrusion 154 is arranged so that it can be sequentially locked into one of the locking recesses 140 to secure the cleaner body 110 in a chosen position, relative to the 30 suction port assembly 130.
The resilient pedal lSO also has a resilient support portion 155 in the form of a plate integrally formed with a lower end of the resilient pedal 150. The resilient pedal 150 is mounted on the mounting portion 137 such that one end of the resilient support portion 155 is supported on an inner wall 137a of the mounting portion 137. The locking 5 protrusion 154 is resiliently biased such that it is urged towards the side surface of the cleaner body l lO so that it can be sequentially locked into one of the locking recesses 140 when the cleaner body 110 rotates to a chosen position. In use, in order for the cleaner body l lO to be released from its current locked position (caused by the locking protrusion 154 being located in one of the locking recesses 140), and to again allow the 10 body to rotate, a resilient pedal portion 153 of the pedal 150 is pressed to pivotally move the pedal 150 and to release the locking protrusion 154 from the locking recess 140 in which it is located.
The locking recesses 140 preferably include an upright position recess 141 and an 15 inclined position recess 142. As will be appreciated, these recesses are formed along a portion of the cleaner body 110 on which the locking protrusion 154 contacts when the cleaner body rotates. When the cleaner body 110 is in an upright position, the locking protrusion 154 locks into the upright position recess 141. Accordingly, the cleaner body 110 is held in the upright portion which may be required, for example, when the 20 upright type vacuum cleaner 100 is not in use. When the upright type vacuum cleaner 100 is in use, with the cleaner body l lO being operated at a predetermined angle with respect to the surface to be cleaned, the locking protrusion 154 locks into one of the inclined position recesses 142. Accordingly, when the vacuum cleaner 100 is lifted over an obstacle during cleaning (such as a surface boundary or threshold) , the suction 25 port assembly 130 rotates no more than a predetermined angle with respect to the cleaner body 110.
In use, the cleaner body 110 of the upright type vacuum cleaner 100 may lie parallel to the cleaning surface, as shown in Figure 3 The locking protrusion 154 is pressed 30 against the side surface of the cleaner body 110 such that the resilient support portion 155 remains subject to an external force that deforms the support portion 155 (see Figures 1 and 2). If the upright type vacuum clear 100 is used in this way for a long
time, the resilient support portion 155 can become permanently deformed. When this happens, there is a problem in that the recovery force of the resilient support portion 155 can be reduced.
5 In addition, when the cleaner body 110 is used in a position whereby it lies parallel to the cleaning surface, the side surface of the cleaner body 1 10 is subject to pressure from the locking protrusion 154 such that there is a contact resistance at the portion between the locking protrusion 154 and the cleaner body 1 10, as the cleaner body 1 10 rotates.
Accordingly, there is also a problem in that the cleaner body does not rotate smoothly 10 due to this resistance.
The present invention has been developed in order to reduce or minimise the above-described disadvantages.
15 In the preferred embodiment, this is achieved by providing an improved construction capable of preventing deformation of part of the resilient pedal and reducing any rotation resistance of the cleaner body.
According to one aspect of the invention, there is provided an upright type vacuum 20 cleaner, comprising: a suction port assembly; a cleaner body pivotally connected to the suction port assembly, the cleaner body and suction port assembly being pivotable with respect to each other; at least one locking recess formed in a side wall of the cleaner body; and a resilient pedal pivotably mounted on the suction port assembly and having a locking protrusion arranged to be sequentially locked in the locking recess when the 25 cleaner body is pivoted with respect to the suction port assembly such that the cleaner body is configured to pivot in a stepwise manner, the or at least one of the locking recesses in which the locking protrusion can be locked comprising a parallel position recess within which the locking protrusion can be locked when the cleaner body pivots to a position parallel with respect to a surface to be cleaned.
According to a second aspect of the invention, there is provided an upright type vacuum cleaner comprising: an elongate cleaner body, a suction unit pivotally connected to the
cleaner body, the suction unit having a lower side arranged to be moved over a cleaning surface, and having a suction port for drawing-in contaminants from the cleaning surface, and locking means arranged to secure the cleaner body in one of a plurality of predetermined positions with respect to the suction unit, one of the predetermined 5 positions being such that the length of cleaner body can be positioned substantially parallel to the suction unit lower side.
In another aspect, the invention provides an upright type vacuum cleaner comprising a suction port assembly, a cleaner body connected to the suction port assembly, the 10 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 15 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.
In a preferred embodiment, a plurality of locking recesses are provided, comprising (a) an upright position recess into which the locking protrusion is locked when the cleaner 20 body is in an upright position with respect to the surface to be cleaned, and (b) one or more inclined position maintaining recesses into which the locking protrusion is locked when the cleaner body pivots at a predetermined angle with respect to the surface to be cleaned. 25 The resilient pedal preferably comprises a pedal body pivotably mounted on the suction port assembly, the pedal body comprising a locking protrusion extending from a side part of the pedal body toward the cleaner body, and a pedal portion which, when subjected to an external force, is arranged to release the locking protrusion from the one or more locking recesses, and a resilient support portion for resiliently urging a side of 30 the pedal body to direct the pedal body in a direction whereby the locking protrusion presses against the cleaner body.
The resilient support portion may comprise a plate element integrally protruding from a lower side of the pedal body, the resilient member having a bent portion supported by an inner wall of the suction port assembly.
5 One or more of the locking recesses may have a slanted surface such that the locking protrusion can be easily released from the locking recess when the cleaner body is rotated towards the upright position.
The invention will now be described, by way of example, with reference to the 10 accompanying drawings, in which: Figure 1 is an exploded perspective view of a conventional upright type vacuum cleaner; 15 Figure 2 is a rear view of part of the vacuum cleaner shown in Figure 1, in an assembled state; Figure 3 is a side view of the upright type vacuum cleaner of Figure 1, when in use; 20 Figure 4 is an exploded perspective view of an upright type vacuum cleaner according to the present invention; and Figure 5 is a perspective view of part of the upright type vacuum cleaner shown in Figure 4, part of the operation of the vacuum cleaner being illustrated.
In the following description, components having constructions and features similar to
those of the conventional vacuum cleaner (described above) are denoted using identical reference numerals and a detailed description of these components is omitted.
30 Referring to Figures 4 and 5, an upright type vacuum cleaner 200 includes a cleaner body 110, and a suction port assembly 130 rotatably connected to the cleaner body 110.
A driving shaft 116 extends through the cleaner body 110 and can rotate in association
with the rotation of a suction motor (not shown) which is built within the cleaner body.
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.
5 The cleaner body 110 has a plurality of locking recesses 240, formed on a lateral side of the body, in proximity to the suction port assembly 130 when the two are connected. A resilient pedal 150, having a locking protrusion 154, is pivotably mounted on the suction port assembly 130. Accordingly, when the cleaner body 110 is rotated with respect to the suction port assembly 130, the locking protrusion 154 may be resiliently 10 locked into one of the sequentially-located locking recesses 240, thereby restricting the rotation of the cleaner body with respect to the suction port assembly 130.
The resilient pedal 150 includes a pedal body 151 and a resilient support portion 155.
The pedal body l S 1 is formed with the locking protrusion 154 extending from one side 15 thereof. A rotation shaft 152 passesthroughthecentreofthepedalbody lSO. A pedal portion 153 is formed on an upper portion of the pedal body l SO. 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. As a result, the pedal portion 153 is exposed at the upper part of the 20 suction port assembly 130. Accordingly, a user can press the top of the pedal portion 153 to pivotally move the pedal body l SO during use of the upright type vacuum cleaner 200. The resilient support portion 155 resiliently urges, or biases, the pedal body 151 in a 25 predetermined direction. In this embodiment, the resilient pedal 150 is provided with a resilient support portion 155 in the Loran of a plate member which protrudes from a lower part of the pedal body 151. The plate member 155 is integrally formed with the pedal body l S 1 and has a bent, or arcuate, portion at the centre part thereof.
30 As described above with reference to Figure 2, the pedal body lS1 is mounted on the mounting portion 137 such that one end of the plate member 155 is supported on an inner wall 137a of the mounting portion 137 (see Figure 2). When the pedal portion
153 is subject to an external force, the pedal body 151 is pivotally moved against its biasing and the plate member 155 becomes deformed. As a result of its resilient characteristics, the plate member 155 exhibits a recovery force when the external force is removed. Indeed, the plate member 155 has a tendency to recover its original shape, 5 and accordingly, the pedal body 151 automatically returns to its initial position. This initial position of the pedal body 151 is the position in which the locking protrusion 154 resiliently presses the lateral side of the cleaner body 110.
The resilient pedal 150 is not limited in construction to that of the preferred 10 embodiment described above. Various changes and modifications can be made wherein the resilient pedal 150 includes a pedal body 151, pivotally mounted on the suction port assembly 130 to allow pivoting when pressure is applied by a user, and a resilient support portion 155 for resiliently urging the pedal body 151 towards the cleaner body 110. A lower portion of the cleaner body 110, i.e. the part which contacts with the locking protrusion 154 of the resilient pedal 150 when the cleaner body 110 rotates, has a partially concaved configuration in which is formed the plurality of locking recesses 240. The locking recesses 240 include an upright position recess 241, an inclined 20 position recess 242, and a parallel position recess 243, as shown in Figure 4.
The upright position recess 241, within which the locking protrusion 154 can be locked, allows the cleaner body 110 to maintain an upright, substantially vertical, position with respect to the cleaning surface. Accordingly, when the vacuum cleaner 200 is not in 25 use (for example, when it is being stored), the cleaner body llO can be fixed in an upright position with respect to the cleaning surface by means of the locking protrusion 154 being locked in the upright position recess 241. The cleaner body 110 is prevented from rotating away from the upright position, regardless of external forces or its own weight. When the locking protrusion engages the inclined position recess 242, the cleaner body 110 is restricted from rotating beyond a predetermined angle defined between the
cleaner body 110 and the suction port assembly 130. That is, when the cleaner body 110 rotates to this predetermined angle, the locking protrusion 154 locks within the inclined position recess 242, thereby preventing the cleaner body 110 from rotating beyond the predetermined angle. Accordingly, if there is a small obstacle ahead of the 5 cleaner, such as a threshold or surface boundary, the upright type vacuum cleaner 200 can be easily lifted to avoid the obstacle during cleaning. Plural inclined position recesses 242 can be provided, if desired.
The parallel position recess 243, into which the locking protrusion 154 may be locked, 10 allows the cleaner body 110 to maintain a parallel position with respect to the cleaning surface. That is, the cleaner body can be maintained substantially horizontal with respect to the surface. When the cleaner body 110 lies in a position parallel to the cleaning surface, the plate member 155 is in a relaxed state. Accordingly, even when the upright type vacuum cleaner 200 is used with the cleaner body 110 lying in the 15 parallel position for a significant amount of time, permanent damage to the plate member 155 is avoided.
The parallel position recess 243 has a slanted surface 243a formed on an inner side thereof. The cleaner body 110 can be easily rotated into an upright position, due to the 20 presence of this slanted surface 243a, the locking protrusion 154 being easily released from the parallel position recess 243. Indeed, as the locking protrusion 154 presses the lateral side surface of the cleaner body 110, it can move along the slanted surface 243a of the parallel position recess 243, and since the plate element 155 is in a relaxed state, the load on the plate member 155 is decreased. Therefore, there is a decreased 25 operating resistance, which can otherwise result when the locking protrusion 154 resiliently presses the lateral side surface of the cleaner body 110. It is preferable for the inclined position recess 242 to have a slanted surface 242a in order to decrease the operating resistance which can result when the cleaner body 110 rotates.
30 In the upright type vacuum cleaner 200 described above, the locking protrusion 154 is locked in one of a number of locking recesses 240 such that the cleaner body 110 is prevented from rotating beyond a desired angle and towards the cleaning surface. In
order for there to be further rotation of the cleaner body 110 (towards the cleaning surface), the locking protrusion 154 has to be released from the locking recesses 240, by means of a user pressing the pedal portion 153 of the resilient pedal to pivot the pedal against its biasing. After the locking protrusion 154 is released from one of the locking 5 recesses 240 so that the cleaner body 110 can rotate, the resilient pedal 150 can automatically pivot in a return direction due to the resilient force of the resilient support portion 155. This allows the locking protrusion 154 to contact the cleaner body 110.
As described, the resilient support portion 155 can be in a substantially relaxed state, 10 even when the cleaner body 110 is in a parallel position with respect to the cleaning surface. In this position, the locking protrusion 154 is locked in the parallel position recess 243 provided on the side surface of the cleaner body 110. Accordingly, the resilient support portion 155 is in a relaxed state even if the cleaner body 110 is maintained parallel to the cleaning surface for a significant period of time. As a result, 15 the resilient support portion 155 is prevented from being permanently deformed.
Further, when the cleaner body 110 is rotated and the locking protrusion 154 moves in proximity to the parallel position recess 243, the resilient support portion 155 is subject to a reduced load due to the presence of the slanted surface 243a formed in the parallel 20 position recess 243. Therefore, this has the effect of decreasing the operating resistance of the rotating operation of the cleaner body 110.
