Description

    FIELD OF THE INVENTION
  • The invention relates to a garment steamer.
  • The invention may be used in the field of garment care.
  • BACKGROUND OF THE INVENTION
  • Stand garment steamers with a pole assembly to which an ironing board is attached, are known. The ironing board is used to create a back support for the garments being steamed.
  • However, in those known devices, the ironing board is attached vertically, which may create some inconveniences when using is steaming a garment against the ironing board.
  • WO 2019/174363 A1 discloses an ironing board assembly and an ironing machine.
  • OBJECT AND SUMMARY OF THE INVENTION
  • It is an object of the invention to propose an improved garment steamer for treating a garment that avoids or mitigates above-mentioned problems.
  • The invention is defined by the independent claim 1. The dependent claims define advantageous embodiments.

    • an ironing board for supporting the garment during treatment,
    • a first pivoting coupling for coupling the ironing board and the upper pole section,
    • a linking arm having a fixed length and being arranged between the ironing board and the middle pole section,
    • a second pivoting coupling for coupling a first end of the linking arm and the ironing board,
    • a third pivoting coupling for coupling a second end of the linking arm and the middle pole section.
  • Since the arm element has a fixed length, the rotation of the ironing board around the first pivoting coupling results in that the height of the first pivoting coupling varies as long as the ironing board rotates. In other words, varying the height of the first pivoting coupling results in a rotation of the ironing board to different angles. The variation of this height is absorbed by the telescopic coupling.
  • This solution provides a simple, straightforward, intuitive, ironing board tilting experience, whereby user can conveniently adjust the ironing board angle.
  • In particular, the ironing board can be tilted up to reaching a horizontal position. This horizontal position for the ironing board bring the same high level of convenience of treating relatively long garments (e.g. pants and formal shirt with long sleeves ) with a steam iron on a traditional horizontal ironing board, but here dealing with a stand garment steamer.
  • Preferably, the garment steamer further comprises a locking mechanism to fix the position of the upper pole section relatively to the middle pole section. This allows a firm locking of the ironing board in a given tilted position.

  • The at least one pin (109a, 109b) and the plurality of holes (HI, H2, H3) create a sound and/or tactile information to user when the matching with a hole occurs.
  • The pin-locking mechanism 106 comprises a pipe wherein the two shaft elements 113a, 113b is are slide-ably housed. Each shaft comprises a pin at the end proximity to the pole which cooperate with holes along length of the upper pole section (U1, U2) to lock it in various position. To reduce the friction between the pin and the holes, a plastic cap made of low friction material (for example POM) is preferably provided over the pin. The cap is secured to the pin by screw. The opposite end of the shaft (away from the telescopic pole) is attached to a slider. The button 107 has a slope surface at its bottom end in sliding contact with a corresponding slope surface on the two sliders 116a, 116b, which causes the sliders to slide horizontally when the button is being pressed, and in turn pull the shaft to disengage the pin from a given hole arranged on the upper pole section. A spring is arranged between the sliders by being attached to the end of the shafts to return it to the lock position (i.e. a given pin at the end of the shaft engages with one hole on the upper pole section).
  • Fig.1A shows the ironing board 103 in vertical position (i.e. 0 degree compared to the vertical direction), the upper pole section U 1 is fully extended and the pin-locking mechanism on the middle pole section M locks the upper pole section U in its extended position.
  • Fig.1B shows the ironing board 103 inclined at an angle (for example 30 degree compared to the vertical direction) by lowering down the upper pole section U. The upper pole section U can be lowered/retracted by pressing the button 107 of the pin-locking mechanism to unlock it and subsequently lock in the lower position when the button is released.
  • Fig.1C shows the ironing board 103 in horizontal position (i.e. 90 degrees compared to the vertical direction), when the upper pole section U is further lowered in the same way by pressing the button 107 to unlock it and subsequently lock it in position by releasing the button.
  • Figs.2A-2B-2C show the interaction of pivot points A, B and C when the upper pole section U moves up or down for different angular orientations of the ironing board 103. It is noted that pivot point A always remains at the same height compared to the base 101.
  • Rotating the ironing board 103 from vertical to inclined/horizontal orientation works as follows:
    1. 1. With the ironing board in vertical state, the pin-lock mechanism locks the upper pole section U in its extended position.
    2. 2. One hand of user is holding the ironing board 103 while another hand of the user is pressing the button 107 of the pin-lock mechanism to activate the sliders to retract the shafts (pin at the end of the shaft) to unlock the upper pole section U.
    3. 3. The upper pole section U can now be freely moved down resulting in shifting the first hole H1 away from the shaft (pin at the end of the shaft).
    4. 4. When the button is released by user, the spring causes pin at the end of the shaft to contact the outer surface of the upper pole section U.
    5. 5. As the upper pole section U continues to move downwards, the pin at the end of the shaft will slot into the next hole (for example second hole H2) of the upper pole section U, resulting in that the ironing board 103 is locked in inclined orientation.
    6. 6. By repeating steps 2 to 5, the ironing board 103 can be tilted up to an horizontal orientation by having the upper pole section U moving down to the lowest position and the pin at the end of the shaft locking into the third hole H3 hole on the upper pole section U.
  • Rotating the ironing board from inclined/horizontal to vertical orientation works as follows:
    1. 1. One hand of user is holding the ironing board 103 while another hand is pressing the button 107 of the pin-locking mechanism to activate both the sliders to retract both side of the shafts (pin at the end of the shaft) to unlock the upper pole section U.
    2. 2. Push the bottom end of the ironing board 103 downwards which in turn moves up the upper pole section U.
    3. 3. When the button 107 is released, the spring causes pin at the end of the shaft to contact the outer surface of the upper pole section U.
    4. 4. As the upper pole section U continues to move upwards, and the pin at the end of the shaft will slot into to the next hole of the upper pole section U.
    5. 5. The ironing would now be in inclined orientation if it was in horizontal orientation previously or it would be in vertical orientation if it was in inclined orientation previously.
