Abstract:
In a floor care nozzle comprising a nozzle housing (HS), a mass (m) is vertically movable and contained (C) within the nozzle housing (HS). Preferably, the nozzle housing (HS) is provided with a damping element (DE) at a place where the mass (m) collides with the nozzle housing (HS), or the mass (m) is provided with a damping element (DE). Preferably, a total weight of the mass (m) is at least about 10% of a weight of the nozzle. Preferably, the mass (m) comprises a plurality of masses (m) distributed over a width of the nozzle housing (HS), wherein the number of masses (m) could be at least 3 and at most 6. Preferably, the nozzle housing (HS) comprises a plurality of containers (C) in which respective masses (m) can move, which are advantageously placed at a front end of the nozzle housing (HS).
Abstract:
A device comprising a first part and a second part that comprise a first fastening tool (FT1), a first receptor (R1), a second receptor (R2) for engaging with the first fastening tool (FT1), and a movable latch (L) for engaging with the first receptor (R1), wherein a single act of engaging the first fastening tool (FT1) with the second receptor (R2) to establish a first connection between the first and second parts, also makes the movable latch (L) engage with the first receptor (R1) to establish a second connection between the first and second parts, the second connection being spaced apart from the first connection, whereby both the first and second connections result from operating only the first fastening tool (FT1).
Abstract:
A device (10) for mounting a motor assembly of an electric appliance such as a vacuum cleaner in a housing (2) of the appliance comprises a resilient mounting body (11) which is intended for arrangement between the motor assembly and the housing (2). An inner peripheral portion (12) of the mounting body (11) comprises a first motor contacting portion (13), a second motor contacting portion (14) being provided with axial motor support components (19), and a connection portion (15) interconnecting the motor contacting portions (13, 14). A radial stiffness of the first motor contacting portion (13) is lower than a radial stiffness of the connection portion (15), so that the extent to which vibrations of the motor assembly are coupled into the mounting body (11) at the position of contact to the first motor contacting portion (13) can be at a minimum.
Abstract:
The present invention relates to an exhaust grille (10, 20, 30, 40). The exhaust grille comprises an array comprising an array of spaced vanes (15) which define a plurality of separate non-linear air flow passages (14) through the grille. The grill is configured so as to deflect sound waves incident upon the grille to prevent them from passing through the passages. Various configurations of exhaust grille are disclosed, and the exhaust grille configuration reduces the noise levels permitted to pass through the grille, for example when placed over an exhaust (2), such as over the exhaust outlet of a vacuum cleaner.
