DETAILED DESCRIPTION OF THE INVENTION

Fig.1A depicts a front view of a garment steamer 100 according to the invention for treating a garment. Fig.1B depicts a side view of Fig.1A.
The garment steamer 100 comprises a base 101.
The garment steamer 100 also comprises a pole assembly 102 extending along a substantially vertical axis YY from the base 101. The pole assembly 102 comprises a first pole 102a and a second pole 102b.
The garment steamer 100 also comprises an ironing board 103 for supporting the garment during treatment.
The garment steamer 100 also comprises a coupling element 104 for coupling the ironing board 103 and the pole assembly 102. The coupling element 104 is adapted to allow a rotation of the ironing board 103 compared to the pole assembly 102 around a first axis A1 being substantially perpendicular to the vertical axis YY.
By "substantially perpendicular", it is meant a difference up to +/- 10 degrees compared to the vertical axis YY.
The garment steamer 100 also comprises a mechanism 105 for setting the rotation angle AA of the ironing board 103 around the first axis A1. The mechanism 105 comprises a lever 106 coupled to the ironing board 103 via a pivot coupling 107 rotating around a second axis A2 parallel to the first axis A1.
The lever 106 comprises a plurality of grooves 108 adapted to cooperate with a stud element 109 protruding from anyone of the first pole 102a and the second pole 102b.
The base 101 preferably contains a steam generator (not shown) and/or a water tank. The steam generator receives water from the water tank to generate steam. A hose cord 111 is connected to the base 101 to carry steam or water to a steamer head 112. The steamer head 112 is intended to apply steam over the garment being treated, using the ironing board 103 as a back support. A support 113 for the steamer head 112 is preferably arranged at an extremity of the ironing board 103.
For sake of clarity, the hose cord 111 and the steamer head 112 are only represented on Fig.1A.
In Fig.1A, the ironing board 103 extends vertically. In other words, the ironing board extends parallel to the substantially vertical axis YY.
The ironing board 103 is intended to be used as a back support for a garment during treatment with the steamer head 116.
Fig.2A depicts a partial rear view of a garment steamer according to the invention, while Fig.2B depicts a zoomed-in view of Fig.2A.
The stud element is fixed compared to the pole, attached to anyone of the two poles 102a/102b, as long as the lever 106 is arranged on the same side as the stud element.
The stub element is preferably cylindrically-shaped, and is for example fixed by screw (not whown) to the pole assembly.
The cooperation of the stud element 109 with one of the grooves, results in that the ironing board 103 takes different inclination angles AA around the first axis A1.
The lever 106 may take different shapes.
In the various drawings, the lever 106 which is represented comprises two grooves G1 and G2, meaning that the ironing board can take two different angular orientation around axis A1. However, a higher number of grooves could be considered similarly.
Fig.3A depicts a first embodiment of a lever 106 used in a garment steamer according to the invention. The lever 106 is overall rectangular. The grooves G1 and G2 are arranged in a bottom part of this rectangular shape.
Fig.3B depicts a second embodiment of a lever used in a garment steamer according to the invention. Fig.3B only differs from Fig.3A in that the lever 106 is shaped differently. The gorooves G1 and G2 are arranged are the same location as in Fig.3A compared to second axis A2. The lever 106 comprises an extended arm (bended portion) where the grooves G1 and G2 are arranged. Compared to Fig.3A, this shape for the lever 106 is less bulky and is cost-saving.
Fig.3C depicts a third embodiment of a lever 106 used in a garment steamer according to the invention. The lever 106 comprises a hollow area HH. The plurality of grooves 108 are arranged along an inner periphery PP of the hollow area HH. Preferably, as illustrated, the hollow area is completely closed.
Preferably, as illustared, the inner periphery PP comprises a curved portion facing the plurality of grooves.
By "curved", it is meant a portion without angular portions to avoid the stud element bumping against some protruding parts inside the hollow area.
For example, the curved portion is a portion of a circle, an arch, or any curved portion.
In the embodiments previously depicted along with Fig.3A-3B-3C, the length of the lever 106 between the second axis A2 and the extremity of the lever held by user, is such as to create a sufficient momentum around the second axis A2 to easily rotating the ironing board. For example, this length of lever 106 is in the range [7;20] cm.
Fig.4A depicts a partial view of a garment steamer according to the invention, with an ironing board extending vertically.
Fig.4B depicts a partial view of a garment steamer according to the invention, with an ironing board being inclined compared to a vertical direction. In this example, the angle AA is 30 degrees.
In the embodiments previously depicted along with Fig.3A-3B-3C, the first groove G1 is arranged such that when the stud element 109 cooperates with the first groove G1, the ironing board 103 is substantially parallel to the vertical axis YY, as illustrated in Fig.4A.
In the embodiments previously depicted along with Fig.3A-3B-3C, the second groove G2 is arranged such that when the stud element 109 cooperates with the second groove G2, the ironing board 103 is rotated with an angle AA being in the range [10;90] degrees compared to the vertical axis YY, as illustrated in Fig.4B.
Seen from a projected vertical plan, the angle between segment A1-G1 and segment A1-G2 corresponds to the rotation angle of the ironing board between two successive positions, when the stud element matches successively with two successive grooves, such as G1 and G2.
Preferably, as illustrated in Fig.4B, the lever 106 is spring-loaded by a spring 110 arranged around the second axis A2.
The spring 110 creates a force momentum such that the grooves are exerting a force onto the stud element.
This spring 110 enhances the lock/unlock feeling before each change of angular position of the ironing board via user action on the lever 106.
Preferably, one extremity of the spring 110 cooperates with a third groove G3 arranged in the lever 106, so that the spring is better kept in position. Another extremity of the spring 110 is in contact with ironing board 103.
Fig.5 depicts a partial view of a garment steamer according to the invention, with a focus on some specific parameters.
Preferably, as illustrated in Fig.5, the projected distance d1 between the first axis A1 and the stud element 109, and the projected distance d2 between the first axis A1 and the second axis A2, have substantially the same value.
This enables a simple and more compact implementation.
By "substantially the same value", it is meant a difference up to +/- 10 % between those distances.
For example, d1=56 mm, and d2 = 60 mm
Preferably, the groves 108 are arranged along the perimeter of a circle with the first axis A1 as the center of the circle.
Preferably, as illustrated in Fig.5, the coupling element 104, the pivot coupling 107 and the stud element 109 are positioned relatively to each other such that the angle BB between:

the projected segment between as first axis A1 and the stud element 109,
the projected segment between the first axis A1 and the second axis A2, is in the range [15;55] degrees, when the ironing board extends parallel to the substantially vertical axis YY.

This angle BB is the consideration to place the pivot coupling 107 and the stud element 109, with the ironing board 103 in vertical position. In other words, the angle BB determines the size of the product.
If the angle BB is smaller than 15 degrees, the pivot coupling 107 and the stud element will clash each other, or they will be too small to have sufficient strength. If the angle is larger than 55 degrees, the pivot coupling 107 will be too much protruding towards the board, or the stud element will be shifted too far away beyond the boundary of the pole assembly opposite to ironing board direction, resulting in unreasonably bulky product.
Having angle BB in the range [15;55] degrees provides an optimal compromise.
Fig.6A and Fig.6B depicts partial views of a lever 106 used in a garment steamer according to the invention, with a focus on some specific parameters.
Preferably, at least one groove taken among the plurality of grooves 108 defines a concave area comprising two opposite walls W1/W2 intended to come into contact with the periphery of the stud element 109.
The principle of locking applies to both the first groove G1 and the second groove G2.
For sake of clarity, only the first groove G1 is represented.
Line A3 is defined as the line connecting the center of pivot coupling 107, and the center of the stud element 109. The locking is characterized in:
The groove G1 (or G2) is having two opposing walls W1/W2 that come into contact with the circumference of the stud element 109. The contact points are the intersection points of line A3 and the circumference of the stud element 109.
This lock ensures that the ironing board cannot rotate about the first axis A1, unless the grooves and the stud element 109 are disengaged by rotating the lever about the second axis A2.
Preferably, the two opposite walls (W1, W2) extend parallel to each other. In other words, the walls W1/W2 are perpendicular to line A3 at those contact points.
Preferably, the walls W1/W2 extend beyond the contact points towards the lead in part of the lock (open end) at a length of > 0.1mm as illustrated in Fig.6A.
Preferably, as illustrated in Fig.6B, in order to facilitate the entry/exit of the stud element 109 into the groove G1/G2, each wall W1/W2 comprises a tapered angle of less than 10 degrees flaring out towards the open end, preferably in the range [5;10] degrees.
Preferably, as illustrated in Fig.6B, the depth of the groove to the point where its width is equal to the diameter of the stud element is larger than the radius of the stud such that the close end of the groove is having a gap preferably larger than 0.1mm with the circumference of the stud element, when the groove is fully engaged with the stud element. This help to ensure that a tight locking.
