First Claim
Patent Images
1. A vacuum cleaner for using both in an upright form and a canister form, comprising:
- a pivot unit formed to pivot a connection pipe disposed between an extended tube and a nozzle body of a suction nozzle assembly, on at least two points,wherein the connection pipe is divided into at least first and second parts, and the pivot unit pivotably connects between the nozzle body and the first part of the connection pipe and between the first and the second parts of the connection pipe,wherein the pivot unit comprises;
a first pivot to connect the first part of the connection pipe to the nozzle body to be able to pivot within a first angle range thereto; and
a second pivot to connect the second part to the first part of the connection pipe to be able to pivot within a second angle range thereto, andwherein, when the vacuum cleaner is used in the canister form, the second part of the connection pipe is fixed approximately parallel to the first part of the connection pipe, and the second part of the connection pipe is operated to pivot within the first angle range about the first pivot.

21. A vacuum cleaner for using both in an upright form and a canister form, comprising:
-
a pivot unit formed to pivot a connection pipe disposed between an extended tube and a nozzle body of a suction nozzle assembly, on at least two points, wherein the connection pipe is divided into at least first and second parts, and the pivot unit pivotably connects between the nozzle body and the first part of the connection pipe and between the first and the second parts of the connection pipe, wherein the pivot unit comprises; a first pivot to connect the first part of the connection pipe to the nozzle body to be able to pivot within a first angle range thereto; and a second pivot to connect the second part to the first part of the connection pipe to be able to pivot within a second angle range thereto, and wherein the first pivot comprises; a first cylinder coupled in fluid communication with one end of the first part to be perpendicular to the first part and having a suction opening; and a supporter formed on the nozzle body to connect the suction opening with an air passage of the nozzle body and to accommodate and rotatably support the first cylinder, wherein the supporter comprises a first pivot-restricting part to prevent the first part from pivoting out of the first angle range.
