DETAILED DESCRIPTION OF THE INVENTION

Fig.1 depicts a garment steamer 100 according to the invention with a board taking a first angular position, and Fig.2 depicts a front view of the garment steamer of Fig.1.

The garment steamer 100 comprises:

a base 101,

a pole assembly 102 mounted on said base 101,

a board 103 connected to the pole assembly 102 via a first pivot coupling Cl extending along an horizontal axis XI,

an arm element 104 arranged between the pole assembly 102 and the board 103.

The arm element 104 comprises a foldable structure adapted to take:

a) a folded configuration in which the length L of the arm element 104 has a first value LI resulting in that the board 103 takes a first angular position compared to the pole assembly 102,

b) an unfolded configuration in which the length L of the arm element 104 has a second value L2 resulting in that the board 103 takes a second angular position compared to the pole assembly 102. The length L corresponds to the straight distance (i.e. span) between the point of connection of the arm element 104 with the board 103, and the point of connection of the arm element 104 with the pole assembly 102.

Preferably, the first pivot coupling Cl is arranged in an upper half portion of the board 103, as illustrated.

Fig.3 depicts the garment steamer 100 according to the invention with a board 103 taking a second angular position.

Fig.4A-Fig.4B-Fig.4C depict various views of a garment steamer 100 according to the invention with a board 103 taking different angular positions between a first angular position and a second angular position.

Fig.4A depicts the garment steamer 100 according to the invention with a board 103 taking a first angular position. The first angular position of the board 103 defines an angle A1 in the range [0;10] degrees between the surface of the board and the vertical direction YY. In this configuration, the arm element 104 is folded and its length L has a value LI, which may be close to 0.

Fig.4C depicts the garment steamer 100 according to the invention with a board 103 taking a second angular position. The second angular position of the board 103 defines an angle A2 in the range [10;90] degrees between the surface of the board and the vertical direction YY. In this configuration, the arm element 104 is unfolded and its length L has a value L2. Preferably, the angle A2 is in the range [20;40] degrees.

Fig.4B depicts the garment steamer 100 according to the invention with a board 103 taking an angular position defining an angle between angle A1 and angle A2. In this configuration, the arm element 104 is between a folded configuration and an unfolded configuration, and its length L has a value between LI and L2. This illustrates an intermediate situation where user is adjusting the angular position of the board to reach either the first angular position or to reach the second angular position. Fig.5 depicts a three-dimensional zoomed-in view of a garment steamer according to the invention with a board taking a second angular position.

The foldable structure of the arm element 104 comprises a first portion PI and a second portion P2 being connected with each other via a second pivot coupling C2.

The first portion PI is connected to the board 103 via a third pivot coupling C3.

Preferably, the third pivot coupling C3 is arranged in a lower portion of the board 103, as illustrated.

A rotatable lever 105 is attached to the board 103 for creating a force FI against said first portion PI to facilitate the rotation of the first portion PI around the third pivot coupling C3 between the unfolded configuration and the folded configuration. The force FI is illustrated in Fig.7 which depicts a cross-section zoomed-in view of a garment steamer according to the invention with a board taking a second angular position.

Fig.6 depicts a cross-section zoomed-in view of a garment steamer according to the invention with a board taking a first angular position,

Preferably, the rotatable lever 105 is spring-loaded with a spring 106.

The pole assembly 102 comprises at least one vertical pole.

The first pivot coupling Cl is arranged at a top part of the at least one vertical pole.

Preferably, as illustrated, the pole assembly 102 comprises a first vertical pole VP1 and a second vertical pole VP2.

Preferably, the rotatable lever 105 comprises a catch element 107 adapted to hook, in the folded configuration of the arm element 104, a first linking element 108 attached to and extending between the first vertical pole VP1 and the second vertical pole VP2. The first linking element 108 for example takes the form of a rod or a bar. Preferably, the first portion PI comprises a rib 109 adapted to rest, in the folded configuration of the arm element 104, against (the top of) the linking element 108. For example, first linking element 108 extends horizontally. The rib 109 is also illustrated in Fig.9.

The catch element 107 and the rib 109 both act to keep the ironing board firm (i.e with less movement) when in the vertical direction.

The second portion P2 is connected to the pole assembly 102 via a fourth pivot coupling C4.

As illustrated, the fourth pivot coupling C4 is arranged around the linking element 108.

Preferably, the second portion P2 defines a V shape having a first leg directing towards the first vertical pole VP1, and a second leg directing towards the second vertical pole VP2. This specific shape of the second portion P2 is advantageous to uniformly transfer the pressing force onto both vertical poles instead of onto the centre point of the first linking element 108, resulting in better balance of the garment steamer.

Preferably, the second portion P2 is detachably connected to the pole assembly 102 by means of locking means.

Preferably, the locking means comprise a first strap element S 1 adapted to lock with the first vertical pole VP1 and a second strap element S2 adapted to lock with the second vertical pole VP2.

Upon locking, strap elements S I and S2 are adapted to provide sufficient gripping onto the vertical poles VP1 and VP2 respectively to prevent S I and S2 from sliding down upon usage, due to repeated pressing force from the board 103. Preferably, a rubber pad 111 is inserted inside the strap elements S I and S2 to provide more effective gripping upon locking. The rubber pad 111 is illustrated in the zoomed-in view of S 1 in Fig.11a.

Preferably, each of the vertical pole VP1 and the second vertical pole VP2 are telescopic in order to vary the overall height of the pole assembly 102. In particular, each of the vertical pole (VP1, VP2) comprises a pair of first and second (hollow) lower parts (VP1_L, VP2_L) cooperating respectively with a pair of first and second upper parts (VP1_U, VP2_U). For example, the upper part VP1_U is adapted to slide into the lower part VP1_L, and the upper part VP2_U is adapted to slide into the lower part VP2_L.

A first locking means TS 1 (for example a manually user-actuatable latch) is used to lock in position the upper part VP1_U with the lower part VP1_L, and a second locking means TS2 (for example a manually user-actuatable latch) is used to lock in position the upper part VP2_U with the lower part VP2_L, as illustrated in Fig.5.

Preferably, with such types of vertical poles VP1 and VP2:

the first strap element S I is locked on the first vertical pole VP1 at a position below the locking means TS 1. In other words, as illustrated, the first strap element S I is locked on the lower part VP1_L.

the second strap element S2 is locked on the second vertical pole VP2 at a position below the locking means TS2. In other words, as illustrated, the second strap element S2 is locked on the lower part VP2_L.

This is advantageous as this allows the strap element S I and S2, upon unlocking, to slide downward along the vertical poles when the upper parts (VP1_U, VP2_U) of the vertical poles VP1 and VP2 are lowered, by telescopically sliding into the lower parts (VP1_L, VP2_L). Once the new height is determined, S 1 and S2 have to be locked back.

The first strap element S I is slidably attached to the first lower part VP1_L, and the second strap element S2 is slidably attached to the second lower part VP2_L. The first and second strap element (S I, S2) offer sufficient gripping on the first and second lower parts (VP1_L, VP2_L) so that the first linking element 108 stays still compared to the pole assembly 102.

Fig.8 depicts a zoomed-in view of a garment steamer 100 according to the invention when the board 103 is taking a first angular position, with the catch element 107 in a hooked position on the first linking element 108.

Fig.9 depicts a detailed zoomed-in view of the garment steamer of Fig.8.

Fig.10 depicts a zoomed-in view of a garment steamer according to the invention with a board 103 taking a first angular position, with the catch element 107 in a non-hooked position on the first linking element 108. This situation happens when the user exerts a force on the lever 105 in the direction Dl, as illustrated in Fig.7.

Fig.11 A- Fig.1 IB depict two views under different angles of a garment steamer according to the invention, with an arm element 104 being detached from a pole assembly 102 of the garment steamer.

Preferably, as illustrated, the first linking element 108 is detachably connected to the first vertical pole VP1 and the second vertical pole VP2. For example, the first linking element 108 extends horizontally between the first lower part VP1_L and the second lower part VP2_L, and is connected to the first lower part VP1_L and the second lower part VP2_L via the locking means comprising a first and second strap elements SI and S2, respectively. Having the first linking element 108 being detachably connected to the pole assembly 102 is advantageous to easily dismantle and store the garment steamer after use.

Coming back to Fig.4A-Fig.4B-Fig.4C, below are described how to move the board 103 from the first angular position (e.g. vertical) to the second angular position (e.g. tilted):

1. User presses the lever 105 towards the front direction Dl (as illustrated in Fig.6).

2. The catch 107 at the back of the board 103 which is originally hold on to the first linking element 108 will be unlocked. This releases the board 103 from its locked vertical position.

3. User continues pulling the board 103 with the same hand that presses the lever, and this will bring the board 103 to its tilted position at the end of travelling.

4. The first portion PI and the second portion P2 are fully extended and they lock the board 103 at its tilted position.

5. The first portion PI and the second portion P2 form a straight line.

6. The lever 105 can be let go the moment after releasing the catch 107 from the first linking element 108. The spring 106 attached to the lever 105 will bring the lever 105 back to its original position.

7. The whole sequential actions allow user to release the locked vertical board position to its fully tilted position in one hand operation.

There is nothing to lock the arm 104 in the extended position. Therefore, the straight line joining C3 and C4 preferably does not pass through C2. Preferably C2 should be slight below the straight line joining C3 and C4. That means PI and P2 form a large angle of slight less than 180 degree for example 177 degree.

Coming back to Fig.4A-Fig.4B-Fig.4C, and Fig.7, below are described how to move the board 103 from the second angular position (e.g. tilted) to the first angular position (e.g. vertical):

1. User presses the lever 105 towards the front direction Dl.

2. An extended arm 110a (illustrated in Fig.7) from the lever 105 pushes against an extended arm 110b of the first portion PI, resulting in an uplift motion D2-D3 at the pivot coupling C2, and then in the collapsing/folding of the first portion PI against the second portion P2.

3. User continues pushing the board 103 towards the pole assembly, which will bring the board back to its vertical position, thus completing the one hand operation of bringing the board to vertical position.

4. The vertical position is locked by the catch 107 that hooks onto the first linking element 108. At the same time, the rib 109 from the first portion PI is resting above the rod first linking element 108. The catch and the rib both act to keep the board 103 firm at its vertical position.

Fig.12 depicts a preferred embodiment of a garment steamer according to the invention.

In this preferred embodiment, a second linking element 112 is arranged between the first pivot coupling Cl and the fourth pivot coupling C4 to maintain a fixed distance between the first pivot coupling Cl and the fourth pivot coupling C4.

By maintaining a fixed distance between the first pivot coupling Cl and the fourth pivot coupling C4, when the user unlocks the locking means TS 1 and TS2 in order to adjust the overall height of the pole assembly 102 by having the upper parts of the pole assembly sliding into the lower parts of the pole assembly, the angle of the ironing board 103 is kept the same.

This is particularly advantageous when the ironing board 103 is already in an inclined (i.e. not vertical) position so that the user can adjust the overall height of the ironing board, without modifying the already set angle of the ironing board. Note that the strap elements S I and S2 do not necessarily need to be unlocked by user if their gripping on the lower parts of the pole assembly still allows, upon a sufficient force exerted by user, a certain sliding along the lower parts of the pole assembly.

After the user has set the pole assembly to the desired overall height, user has to lock again the locking means TS 1 and TS2.

Preferably, the second linking element 112 comprises an upper extremity 112_U connected with the first pivot coupling Cl, and a lower extremity 112_L connected with the first linking element 108.

For example, as illustrated, the second linking element 112 is“A” shaped. In that case, the lower extremity 112_L has two contact points with the first linking element 108. This improves the stability and robustness of the second linking element 112.

Fig.13 depicts an exploded view of an ironing board 103 used along with a garment steamer according to the invention.

Preferably, the second linking element 112 comprises a first part PA1 and a second part PA2. The first part PA1 and the second part PA2 are detachably connected. For example, a snap-fit mechanism SF can be used to this end.

Having the second linking element 112 in two parts is advantageous in order to minimize the overall size of the packaging of the garment steamer, in particular when the ironing board 103 also comprises two parts detachably connected, as illustrated.

The above embodiments as described are only illustrative, and not intended to limit the technique approaches of the present invention. Although the present invention is described in details referring to the preferable embodiments, those skilled in the art will understand that the technique approaches of the present invention can be modified or equally displaced without departing from the protective scope of the claims of the present invention..
