TECHNICAL FIELD
[0001] The present disclosure relates to a clothes care product. In particular, it relates
to a foldable clothes care product such as an ironing board or a clothes drying rack.
BACKGROUND
[0002] Foldable clothes care products such as foldable clothes drying racks typically have
a clothing support part, for example a frame with wires onto which garments may be
hung. Moreover such clothes care products may be of a type that has an X-shaped leg
structure. For such configurations, the legs arranged to support the clothing support
part can be pivotally connected to each other. A first leg having a proximal leg part
and a distal leg part relative to the clothes support part may furthermore be provided
with a knee-joint structure above the pivot connection between the two legs to facilitate
folding of the clothes care product.
[0003] In order to maintain a clothes drying product of the above type in its unfolded state,
i.e. with the legs being in an unfolded position, it may be provided with a knee-joint
locking member. The knee-joint locking member is intended to prevent pivoting of the
upper leg part and the lower leg part about the pivot axis of the knee-joint structure
when the clothes care product is in the unfolded state.
[0004] Currently there are several types of knee-joint locking members available on the
market. One type of knee-joint locking member is a ring. The ring is loosely arranged
around the proximal leg part, allowing it to slide onto the knee-joint structure by
gravity. Moreover, the knee-joint structure has a distal knee-joint part mounted to
the distal leg part. This distal knee-joint part is provided with a free ended bridging
portion which in the unfolded position of the first leg extends from the distal leg
part beyond the pivot axis to the proximal leg part. When the clothes care product
is unfolded, gravitation causes the ring to fall down around the knee-joint structure,
and in particular around the bridging portion. The first leg will thus be prevented
from folding until the ring is lifted from the knee-joint structure by the user.
[0005] Another knee-joint locking member type on the market is similar to the ring described
above. This alternative ring, however, has a locking arm pointing towards the knee-joint
structure and arranged generally parallel with the proximal leg part. When this ring
falls down by gravity, the locking arm falls in between the knee-joint cap portion
of the knee-joint structure and the joint that enables pivoting of the proximal leg
part and the distal leg part. The locking arm is thereby wedged between the joint
and the knee-joint cap portion, thus preventing the proximal leg part and the distal
leg part from pivoting about the joint.
[0006] Both of the above designs are somewhat unreliable, as there is a risk that the ring
may fail to fall into the proper position once the clothes care product is unfolded.
There is hence a risk that the knee-joint locking members will not provide the intended
locking functionality, and the clothes care product could in this case be folded unintentionally.
SUMMARY
[0007] In view of the above, an object of the present disclosure is to provide a clothes
care product which solves or at least mitigates the problems of the prior art.
[0008] There is hence provided a clothes care product comprising a clothing support part,
and a leg frame arranged to support the clothing support part, which leg frame includes
a first leg having a proximal leg part and a distal leg part, wherein the proximal
leg part is pivotally connected to the clothing support part whereby a first pivot
axis is formed, and wherein the proximal leg part is pivotally connected to the distal
leg part thereby forming a knee-joint having a folding axis, a second leg pivotally
connected to the clothing support part, and which second leg is pivotally connected
to the distal leg part forming a second pivot axis. The leg frame furthermore includes
a knee-joint locking member immovably attached to only one of the proximal leg part
and the distal leg part, which knee-joint locking member has a free end bridging portion
that extends axially beyond the knee-joint, and which free end bridging portion has
a flexible tab, wherein the flexible tab has an inner surface provided with a protrusion
that extends from the inner surface in a direction parallel to the folding axis, and
which protrusion is arranged to prevent the first leg in a fully unfolded position
from folding.
[0009] The clothes care product will thus be prevented from folding when placed in the unfolded
position. The knee-joint locking member with its flexible tab allows the first leg
to be fully unfolded. When a portion of the first leg passes by the protrusion during
folding, the flexible tab will flex away from this portion of the first leg, allowing
the first leg to be set in its unfolded position. To this end, in contrast to the
prior art the knee-joint locking member will always prevent a fully unfolded or extended
first leg from folding. In order to set the clothes care product in its folded state,
the user may lift, or flex, the flexible tab away from the first leg to allow the
first leg past the protrusion during folding.
[0010] According to one embodiment the protrusion is wedge-shaped in a cross section of
the knee-joint locking member.
[0011] According to one embodiment in said cross-section, the protrusion has an increasing
thickness in a direction from a distal edge of the flexible tab towards the protrusion,
the direction being parallel with the inner surface, thereby forming the wedge-shape.
The protrusion hence facilitates for the first leg to be placed in the unfolded position.
[0012] According to one embodiment the protrusion has a blocking surface essentially perpendicular
to the inner surface of the flexible tab, which blocking surface is arranged to prevent
the first leg in a fully unfolded position from folding. The knee-joint locking member
may thereby more efficiently prevent folding of the first leg. With essentially perpendicular
is here meant that the blocking surface may be at angle of from 70 degrees with the
inner surface to 110 degrees with the inner surface, preferably 80 to 100 degrees,
even more preferably 85 to 95 degrees, and most preferably at 90 degrees.
[0013] According to one embodiment the protrusion has a longitudinal extension generally
parallel with the longitudinal extension of the knee-joint blocking member.
[0014] According to one embodiment in a cross-section the knee-joint locking member surrounds
a portion of the periphery of the first leg.
[0015] According to one embodiment the knee-joint locking member surrounds at least 40%
of the periphery of the first leg.
[0016] According to one embodiment the proximal leg part includes a first knee plate member
and the distal leg part includes a second knee plate member, which first knee plate
member and second knee plate member form the knee-joint, wherein the knee-joint locking
member is immovably attached to only one of the first knee plate member and the second
knee plate member, and wherein the protrusion is arranged to restrict movement of
the other one of the first knee plate member and the second knee plate member in the
unfolded position of the first leg.
[0017] According to one embodiment the free end bridging portion has a J-shaped or U-shaped
cross-section, and wherein the flexible tab forms the open end of the straight portion
of the J or U.
[0018] According to one embodiment the flexible tab defines a plane, wherein the flexible
tab is flexible in the normal direction of the plane.
[0019] According to one embodiment the knee-joint locking member is made of a plastic material.
[0020] According to one embodiment the clothing support part is an ironing board top, and
wherein the clothes care product is an ironing board.
[0021] According to one embodiment the clothing support part comprises a frame and wires,
wherein the clothes care product is a clothes drying rack.
[0022] Generally, all terms used in the claims are to be interpreted according to their
ordinary meaning in the technical field, unless explicitly defined otherwise herein.
All references to "a/an/the element, apparatus, component, means, etc. are to be interpreted
openly as referring to at least one instance of the element, apparatus, component,
means, etc., unless explicitly stated otherwise.

DETAILED DESCRIPTION
[0024] The inventive concept will now be described more fully hereinafter with reference
to the accompanying drawings, in which exemplifying embodiments are shown. The inventive
concept may, however, be embodied in many different forms and should not be construed
as limited to the embodiments set forth herein; rather, these embodiments are provided
by way of example so that this disclosure will be thorough and complete, and will
fully convey the scope of the inventive concept to those skilled in the art. Like
numbers refer to like elements throughout the description.
[0025] The present disclosure relates to a foldable clothes care product. The clothes care
product may for example be an ironing board or a clothes drying rack.
[0026] The clothes care product comprises a clothing support part for supporting garments.
Moreover, the clothes care product comprises a leg frame arranged to support the clothing
support part. The leg frame is foldable relative to the clothing support part, and
includes a first leg and a second leg.
[0027] The first leg and the second leg are arranged in an X-configuration, i.e. the first
leg and the second leg form cross shaped legs or X-shaped legs. To this end, the first
leg is pivotally connected to the clothing support part. A first pivot axis is thus
formed by the connection between the first leg and the clothing support part. The
second leg is also pivotally connected to the clothing support part. The first leg
and the second leg are furthermore pivotally connected to each other, forming a second
pivot axis.
[0028] The first leg includes a proximal leg part and a distal leg part. The proximal leg
part and the distal leg part are pivotally connected to each other forming a knee-joint
having a folding axis. The first leg is thereby manoeuvrable between a folded position
in which the angle between the proximal leg part and the distal leg part is essentially
0 degrees, and an unfolded position in which the angle between the proximal leg part
and the distal leg part is approximately 180 degrees. The second leg is pivotally
connected to the distal leg part. To this end, the knee-joint, and thus the folding
axis, is arranged between the first pivot axis and the second pivot axis, in particular
when the first leg is in its extended position, i.e. in the unfolded position.
[0029] The clothes care product has a knee-joint locking member immovably attached to the
first leg. With the term "immovable" is herein meant that the knee-joint locking member
is immovable relative to the first leg after the knee-joint locking member has been
mounted to the first leg. It does however not necessarily mean that the knee-joint
locking member cannot be disassembled from the first leg. In use of the clothes care
product, the knee-joint locking member is thus fixedly and immovably attached to the
first leg.
[0030] The knee-joint locking member has means for locking the first leg in the unfolded
position. In particular, the knee-joint locking member is immovably attached to only
one of the proximal leg part and the distal leg part, and has a free ended bridging
portion which extends axially beyond the knee-joint. The bridging portion has a flexible
tab. The bridging portion may be arranged to surround a portion of that leg part of
the proximal leg part and the distal leg part to which it is not immovably attached
to.
[0031] The knee-joint locking member has an inner surface. A portion of the inner surface
is in contact with that leg part of the proximal leg part and the distal leg part
to which it is mounted. The inner surface extends also to the bridging portion and
thus to the flexible tab. The inner surface of the flexible tab is provided with a
protrusion that extends from the inner surface in a direction parallel with the folding
axis. The flexible tab and the protrusion are designed to allow full unfolding the
first leg, and to prevent the first leg from folding when in the unfolded position.
[0032] An example of a clothes drying rack will now be described with reference to Figs.
1-6. Although the example in Fig. 1 depicts a clothes drying rack, it should be clear
that any aspect relating to the leg frame and in particular the knee-joint locking
member equally applies also to ironing boards according to the present disclosure.
[0033] With reference to Fig. 1 an example of clothes care product 1 is shown. Clothes care
product 1 has a clothing support part 3. The clothing support part 3 is arranged to
support garments. The exemplified clothing support part 3 includes a frame 3a, two
foldable wings 3b pivotally mounted to the frame 3a, and wires 3c arranged inside
the frame 3a and the wings 3b for hanging clothes. It should be noted that instead
of two wings, there could instead only be one wing provided, or even no wing at all.
[0034] For a clothing support part of an ironing board, the clothing support part is formed
by the ironing board top and any components to which the leg frame may be mounted.
[0035] Clothes care product 1 further comprises a leg frame 5 arranged to support the clothing
support part 3. The leg frame 5 includes a first leg 7 and a second leg 9. The first
leg 7 has a proximal leg part 7a and a distal leg part 7b. The proximal leg part 7a
is pivotally connected to the clothing support part 3. A first pivot axis 11 is hereby
formed therebetween. The proximal leg part 7a and the distal leg part 7b are pivotally
connected to each other. A knee-joint 8a having a folding axis 13 is thereby formed.
The proximal leg part 7a and the distal leg part 7b are manoeuvrable between a folded
position and an unfolded position relative to each other.
[0036] The first leg 7 and the second leg 9 are pivotally connected to each other. A second
pivot axis 15 is thereby formed therebetween. In particular, the second leg is pivotally
connected to the distal leg part 7b. In a fully unfolded position of the proximal
leg part 7a and the distal leg part 7b, the folding axis 13 is located between the
first pivot axis 11 and the second pivot axis 15.
[0037] The leg frame 5 furthermore includes a knee-joint locking member 17. The knee-joint
locking member 17 is arranged to prevent the first leg 7 from folding when the first
leg 7 is arranged in the fully unfolded position.
[0038] According to the example in Fig. 1, the first leg 7 has two knee-joints 8a, 8b, however
only one of the knee-joints 8a, 8b is provided with a knee-joint locking member 17.
It suffices to provide only one of the knee-joints 8a, 8b with a knee-joint locking
member 17 to ensure proper locking of the clothes care product 1 in the fully unfolded
position. It furthermore facilitates for a user to only have to handle one knee-joint
locking member 17 when folding the first leg 7 in order to set the clothes care product
in its folded state. Nevertheless, it should however be noted that according to one
variation both knee-joints may be provided with a respective knee-joint locking member.
[0039] Fig. 2 shows a perspective view of an example of a longitudinal knee-joint locking
member 17. The exemplified knee-joint locking member 17 is formed in one part. It
may for example be moulded in a single piece. Alternatively, the knee-joint locking
member could be assembled of several parts.
[0040] The knee-joint locking member 17 has a mounting portion 17a arranged to be placed
around the first leg 7. The mounting portion 17a is provided with means 17b for assembling
the knee-joint locking member 17 with the first leg 7, in particular with only one
of the proximal leg part 7a and the distal leg part 7b. Such means 17b may for example
include two oppositely arranged radially inwards extending protrusions arranged to
be received in corresponding openings of the first leg 7.
[0041] The exemplified knee-joint locking member 17 has oppositely arranged lateral cut-outs
17c arranged to accommodate the knee-joint 8a.
[0042] The knee-joint locking member 17 furthermore has a bridging portion 17d. The mounting
portion 17a and the bridging portion 17d are connected via the intermediate portion
provided with the lateral cut-outs 17c. The bridging portion 17d forms a free end
of the knee-joint locking member 17 when assembled with the first leg 7 and extends
beyond the knee-joint 8a and thus the folding axis 13. The bridging portion 17d has
a flexible tab 17f. The flexible tab 17f has an inner surface 17e provided with a
protrusion 17g. The protrusion 17g may have a longitudinal extension generally parallel
with the longitudinal extension of the knee-joint locking member 17.
[0043] The exemplified knee-joint locking member 17 is also provided with a grip 17h, as
shown in Fig. 3. In particular, the flexible tab 17f is provided with the grip 17h.
The grip 17h facilitates gripping of the flexible tab 17h when the first leg 7 is
to be folded, as will be described in more detail in the following. The knee-joint
locking member may according to one variation be without the grip.
[0044] Fig. 4 shows a top view of the knee-joint locking member 17. According to the example,
the knee-joint locking member 17 has a body 18 arranged to surround a portion of the
first leg 7. In cross-section of the knee-joint locking member 17 and first leg 7,
this portion may correspond to more than 40% of the periphery of the first leg 7,
for example more than 45%, such as 50 %, i.e. half of the first leg 7. The knee-joint
locking member 17 may thus be curved; it may for example have a J-shaped cross-section
or a U-shaped cross-section. The flexible tab 17f may for example constitute the straight
end portion of this J or U. The flexible tab 17f may hence form a tangent to the curve
formed by the body 18.
[0045] In cross-section, which can also be seen in the top view in Fig. 4, the protrusion
17g of the exemplified knee-joint locking member 17 is wedge-shaped. In particular,
the thickness, or a dimension, of the protrusion 17g increases in a direction A. Direction
A is defined from the distal edge 17i of the flexible tab 17f towards the protrusion
17f along the inner surface 17e of the flexible tab 17f. This increase in thickness
may be continuous and linear, as shown in Fig. 4, or it may be obtained by a number
of discrete steps. The protrusion may have a thickness decreasing in direction A.
Alternatively the protrusion may have other cross-sectional shapes, e.g. it may be
polygonal, e.g. rectangular.
[0046] The protrusion 17g has a blocking surface 17j arranged to prevent the first leg from
folding when in the fully unfolded position. The angle α between the blocking surface
17j, or more exactly between a plane defined by the blocking surface 17j, and the
inner surface 17e is preferably about 90 degrees, for example between 70 and 110 degrees,
such as 80 to 110 degrees, 80 to 100 degrees, 85 to 95 degrees or 90 degrees. The
flexible tab 17f may be flexible in a direction B, which is parallel to a normal direction
of a plane defined by the flexible tab 17f, or by the inner surface 17e.
[0047] Fig. 5 shows the knee-joint locking member 17 mounted to the first leg 7. According
to the example in Fig. 5, the knee-joint locking member 17 is immovably mounted to
the distal leg part 7b, but could alternatively be immovably mounted to the proximal
leg part 7a.
[0048] According to the example in Fig. 5, the proximal leg part 7a includes a first knee
plate member 19 and the distal leg part 7b includes a second knee plate member 21.
The first knee plate member 19 and the second knee plate member 21 form the knee-joint
8a. The knee-joint locking member 17 may be seen to form a knee cap of the knee-joint
8a. It is to be noted that in Fig. 5, a joint member, e.g. a rivet or a bolt, which
connects the openings 23 defining the folding axis 13 is not shown.
[0049] The first knee plate member 19 and the second knee plate member 21 may be made of
a thin sheet material for example sheet metal, or alternatively they may be moulded
metal or plastic parts. The first knee plate member 19 and the second knee plate member
21 may have U-shaped cross-sections. The knee-joint locking member 17 may be arranged
to receive the first knee plate member 19 and the second knee plate member 21. The
knee-joint locking member 17 is in particular arranged to be mounted around a portion
of the first knee plate member 19 or the second knee plate member 21. In the example
depicted in Fig. 5, means 17b are received by corresponding openings in a knee plate
member, in this case the second knee plate member 21.
[0050] The protrusion 17g is arranged to prevent the edge 19a of the first knee plate member
19 from moving beyond it when the first leg 7 is arranged in the fully extended position.
Of course, it could also be that, in case the knee-joint locking member 17 would be
mounted to the first knee plate member, the protrusion would prevent the corresponding
edge of the second knee plate member from moving beyond it in the fully extended position
of the first leg 7.
[0051] In Fig. 5, it can furthermore be seen that the bridging portion 17d extends beyond
the knee-joint 8a and the folding axis 13. In this case the bridging portion 17d extends
from the distal leg part 7b to the proximal leg part 7a, but it could alternatively
be the other way around, if the knee-joint locking member is mounted to the first
knee plate member.
[0052] When a user intends to set the clothes care product in an unfolded state, the user
pivots the distal leg part 7b about the folding axis 13. The knee-joint locking member
17 is immovably mounted to the distal leg part 7b, but is not in any way attached
to the proximal leg part 7a. As the distal leg part 7a is pivoted towards the proximal
leg part 7a, the angle between the bridging portion 17d and the proximal leg part
7a will decrease until the proximal leg part 7a, especially the back of the first
knee plate member 19 reaches the protrusion 17g. Due to the wedge-shaped design of
the protrusion 17g, outward flexing of the flexible tab 17f is facilitated. The first
knee plate member 19 will thus be able to pass by the protrusion 17g and the first
leg 7 obtains its unfolded position shown in Fig. 5. The proximal leg part 7a and
the distal leg part 7b are now prevented or at least severely restricted from pivoting
relative to each other.
[0053] When a user desires to fold the first leg 7 in order to set the clothes care product
in its folded state, the user may flex the flexible tab 17f outwards to enable the
first knee plate member 19 to move past the protrusion 17g. In order to facilitate
for a user to perform this operation, the user may grab the grip 17h to do so.
[0054] The knee-joint locking member 17 may for example be made of plastic or any other
suitable material that has high mechanical strength and which is flexible enough to
allow multiple flexing of the flexible tab without plastic deformation.
[0055] The inventive concept has mainly been described above with reference to a few examples.
