Description

Technical Field

[0001] The present invention relates to a device for attaching a slat of a slatted base for supporting a person or an object on a support surface, to a slatted base frame.Background art

[0002] Slatted bases are widely used in beds and / or seating furniture to provide a comfortable and supportive basis for mattresses, cushions, or other surfaces for lying or sitting on. An essential part of a slatted base is the attachment of the slats to the edge of the slatted base. Traditionally, these slats are often fixed with rigid connections, which can lead to limitations in the flexibility and adjustability of the slatted base.

[0003] There is a growing need for systems that not only ensure a solid attachment of the slats, but also adjustability in the height of the slats. Such height adjustability is desired per individual slat or per group of slats. This particularly important for adapting the support to the individual needs of the user. In this way, sleeping comfort can be improved.

[0004] Adapting the support of a slatted base to the body shape and characteristics of the user, in order to provide personalized sleep solutions, is done in the prior art, for example, by means of a setting recommendation for zones in a support surface formed by slats of a slatted base. This setting recommendation comprises a specific height setting per zone of the support surface formed by the slats of the slatted base. A slatted base height profile contains a value per zone of the support surface, preferably encoded, which corresponds to the height setting for the respective zone. The Ergosleep ®< Sleep DNA ®< of a user is a slatted base height profile based on a three-dimensional body scan of the user, in combination with anthropometric data, such as height and body weight. Scan and data are processed via a scientifically grounded algorithm into a setting recommendation for twelve zones of a support surface that can be adjusted in an Ergosleep ®< sleep system. The twelve zones divide the length of the support surface into twelve equal parts. In this way, the most important ergonomic zones (head, shoulder, waist, hip, upper and lower legs) can each individually receive the support they need. This setting recommendation is stored in the Ergosleep ®< Sleep DNA ®< of the user as twelve values, with one value per zone. The value for a zone represents one of four standard height settings used in an Ergosleep ®< Sleep DNA ®< . The same height difference separates every two successive height settings. In an Ergosleep ®< Sleep DNA ®< , the value per zone is recorded with a color coding, called the Ergosleep ®< Sleep DNA ®< color coding. Each color thus corresponds to a height setting.

[0005] Devices for attaching a slat of a slatted base to a slatted base frame with the possibility of height adjustment are known in the prior art. For instance, patent publication EP1013200 A1 describes a device for attaching a slat of a slatted base for supporting a person or an object on a support surface formed by the slats of the slatted base, to a slatted base frame, comprising a spring extending between a first spring end and a second spring end, configured in use to resiliently connect the support surface to the slatted base frame in a height direction transverse to the support surface, a connecting means at the first spring end configured in use to connect the spring to the slatted base frame, at least one slat holder configured in use to receive the slat, a height adjuster, configured in use to adjust a distance between the slat and the slatted base frame according to the height direction.

[0006] It is a disadvantage of the prior art that setting the height of a slat on a slatted base frame is difficult, because the mechanism is not easy to reach or because the mechanism is not convenient to use.Description of the invention

[0007] It is an object of the present invention to solve at least a part of the problems of the prior art.

[0008] The present invention provides a device for attaching a slat of a slatted base for supporting a person or an object on a support surface formed by the slats of the slatted base, to a slatted base frame. A slatted base frame is a load-bearing, preferably rigid, construction of a slatted base, as known from the prior art, such as for example a perimeter structure of a slatted base, or two slatted base edges connected by a connecting beam. A person is for example supported by the slats of a slatted base when this person is lying on a mattress which rests on the slatted base. An object supported by the slats of a slatted base is preferably a mattress.

[0009] The device comprises a spring extending between a first spring end and a second spring end, configured in use to resiliently connect the support surface to the slatted base frame in a height direction transverse to the support surface. The spring is a slat suspension element as known from the prior art, such as for example a flexural arm, a pocket spring, a leaf spring, a plastic spring. The device further comprises a connecting means at the first spring end configured in use to connect the spring to the slatted base frame, such as for example a plate provided with holes through which the device can be fastened to the bed edge using screws or bolts. The connecting means may also comprise a dowel. The device comprises at least one slat holder configured in use to receive the slat and a height adjuster, configured in use to adjust a distance between the slat and the slatted base frame according to the height direction. The height adjuster is provided between the second spring end and the slat holder. The height adjuster comprises an adjusting screw and a sleeve, which is preferably tubular. The adjusting screw is rotationally, preferably threadedly, connected to the sleeve and the movement of the adjusting screw relative to the sleeve is configured in use to change the distance between the slat and the slatted base frame according to the height direction.

[0010] Preferably, the adjusting screw and the sleeve are configured in use together to move the adjusting screw linearly relative to the sleeve when the adjusting screw rotates.

[0011] Preferably, the adjusting screw extends between a first adjusting screw end and a second adjusting screw end and the adjusting screw comprises a head at the second adjusting screw end, and a shank between the head and the first adjusting screw end. The head comprises a first engagement point configured to be engaged by a gripper, such as for example a hexagon for gripping with an adjustable wrench, or a recess for a screwdriver end - the screwdriver end is also called a screwdriver tip or screwdriver head - according to the prior art, such as for example a slot for a flathead screwdriver, a cross for a Phillips screwdriver, a cross for a Pozidriv screwdriver, a star-shaped hole with six vertices in which a Torx key fits, or a hexagonal hole in which an Allen key fits. Preferably , a screw thread having a pitch is provided around the shank. The screw thread is a lead screw thread, which serves specifically for moving parts, such as for example a screw thread with, for example, a rectangular or trapezoidal profile. The pitch is the linear distance between two corresponding points of the same helix, being the displacement along the axis per revolution. The height adjuster is not located between the spring and the slatted base frame, but between the spring and the slat. The height adjuster may have different orientations relative to the slatted base frame, and be rotated from a side, the top, or the bottom of the slatted base.

[0012] It is an advantage of the present invention that the height adjuster becomes more accessible and adjusting the height of a slat becomes easier. It is an additional advantage that a screwdriver or other tool can be used when setting the height, whereby the required force can be reduced through leverage and the accuracy of the height setting can be increased. Furthermore, the force transmission from the hand of the person setting the height can be controlled more easily. It is an additional advantage that, through the use of an adjusting screw, the height adjustment does not require any parts to be disassembled, which leads to a further simplification of the adjustment of the height of a slat. Furthermore, the risk of damage resulting from the disassembly of parts during height adjustment is lowered. It is an additional advantage that setting and personalizing a complete bed according to a personalized slatted base height profile, such as for example an Ergosleep ®< Sleep DNA ®< , can be performed faster and more easily. It is an additional advantage that the attachment of the device to the slatted base frame can be performed faster and with fewer errors, because the attachment is simplified, as the height adjuster is not located near the connecting means at the first spring end.

[0013] Preferably, the adjusting screw extends according to the height direction, the first spring end is configured in use to be located further from the support surface in the height direction than the second spring end, the first adjusting screw end is located closer to the first spring end than the second adjusting screw end, and the second adjusting screw end is located closer to the second spring end than to the first spring end. The adjusting screw can be rotated from the top of the slatted base.

[0014] It is an advantage of the present invention that the height adjuster can be simplified because the adjusting screw moves in the direction of the height adjustment. It is an additional advantage that the head is transverse to the support surface and points towards the support surface, making the adjusting screw more accessible, particularly when two slatted bases are placed next to each other in a double bed.

[0015] Optionally, the sleeve is configured in use to abut against a braking surface at the first spring end when a distance between the first spring end and the second spring end is equal to a minimum distance between the first spring end and the second spring end, and the sleeve is configured in use, in cooperation with the braking surface, to keep a distance between the first spring end and the second spring end equal to or greater than the minimum distance between the first spring end and the second spring end. If the distance between the first spring end and the second spring end becomes smaller than the minimum distance between the first spring end and the second spring end, the spring is outside its elastic zone and can be damaged.

[0016] It is an advantage of the present invention that a mechanism exists which protects the spring against permanent deformation. This extends the service life of the device. It is an additional advantage that the device has elements that have a multiple function, such as the sleeve receiving the adjusting screw as well as protecting the spring. This leads to a simplification of the system.

[0017] Preferably, the height adjuster comprises a screw cage and a screw cage guide. Preferably, the adjusting screw is rotationally connected to the screw cage, the screw cage guide is connected to the sleeve, the screw cage guide is translationally connected to the screw cage. The screw cage is configured in use to move translationally according to the height direction along the screw cage guide when the adjusting screw rotates and comprises a first screw cage surface. Preferably, the first screw cage surface is configured in use to shield the adjusting screw from contact in a direction transverse to the first screw cage surface, and configured in use to be translationally connected to the screw cage guide. Preferably, the screw cage and screw cage guide comprise a cooperating screw cage guide groove and screw cage guide lip and the screw cage guide groove is configured in use to receive the screw cage guide lip.

[0018] It is an advantage of the present invention that the screw cage guides the movement according to the height direction and thereby minimizes lateral forces on the adjusting screw. It is a further advantage of the present invention that it reduces the risk of injury from touching the adjusting screw, because this contact is made more difficult. The risk of damage to the adjusting screw is also reduced. It is a further advantage of the present invention that the risk of an incorrectly fitting screw cage and screw cage guide is reduced, particularly when the screw cage guide groove and / or screw cage guide lip break a circular symmetry of the screw cage.

[0019] Preferably, the screw cage is configured in use to move along the screw cage guide between a first screw cage position and a second screw cage position, and the screw cage and / or screw cage guide comprise a screw cage blocking mechanism, such as for example an end stop, an abutment, a mechanical stopper, a locking pin, configured in use to stop the screw cage when the screw cage is in the first screw cage position and / or when the screw cage is in the second screw cage position, so that the screw cage can only move between the first screw cage position and / or second screw cage position.

[0020] It is an advantage of the present invention that an accidental disconnection of the screw cage from the screw cage guide is avoided, making the device safer and facilitating the setting of the device.

[0021] Preferably, the head comprises a flange transverse to the shank, the screw cage comprises a bearing surface, the bearing surface is arranged transverse to the height direction and against the flange, the bearing surface is provided with a first through-hole, the adjusting screw extends through the first through-hole, and the flange is located on the other side of the bearing surface than the second adjusting screw end.

[0022] It is an advantage of the present invention that the screw cage and adjusting screw are connected in a simple manner and the movement of the adjusting screw is transferred in a simple way to the screw cage, particularly when the head is transverse to the support surface and points towards the support surface. It is an additional advantage of the present invention that it combines simple access to the first engagement point with a simple connection between adjusting screw and screw cage.

[0023] Optionally, the adjusting screw comprises an adjusting screw lock, configured in use to lock the adjusting screw. The adjusting screw lock comprises a locking spring, a locking element, and a catch. The locking element is configured in use to move between a first locking element position and a second locking element position and to be received by the catch when it is in the second locking element position. The locking spring is provided to keep the locking element in the second locking element position. The adjusting screw lock is configured in use to lock the adjusting screw rotationally when the locking element is in the second locking element position.

[0024] It is an advantage of the present invention that it protects against an unintentional adjustment of the height.

[0025] Preferably, the adjusting screw lock further comprises a locking cover and the locking element comprises a locking head. The locking head is arranged translatably according to the height direction between the first locking element position and the second locking element position relative to the screw cage, and arranged rotatably relative to the screw cage. The locking head extends in the height direction between a first locking head end and a second locking head end and comprises at the first locking head end a first gripper, such as for example a projection, such as for example a tooth or a screwdriver end, configured in use to engage the first engagement point. The locking head is configured in use to rotate the adjusting screw when the locking head rotates. The locking head comprises at the second locking head end a second engagement point, configured to be engaged by a gripper. This second engagement point is preferably similar to the first engagement point. The locking head comprises at the second locking head end at least one protrusion, such as for example a tooth. The locking cover is connected to the screw cage and comprises a cover surface transverse to the height direction. The locking cover comprises a locking recess, such as for example a groove. The catch comprises the locking recess. The locking recess is configured in use to receive the protrusion, when the locking head is in the second locking element position. The locking head is configured in use to lock rotationally when the locking recess receives the protrusion. The locking spring, such as for example a disc spring or other spring known from the prior art, is provided to push the locking head against the locking cover surface and is configured in use to keep the protrusion in the locking recess when the locking head is in the second locking element position. The cover surface comprises a second through-hole, which is aligned with the second locking head end.

[0026] It is an advantage of the present invention that releasing the lock to rotate the adjusting screw is simplified. The user can release the lock with the tool used to rotate the adjusting screw, wherein the rotation is enabled by pressing in the locking head with the tool. This simplification is enhanced, in particular when the head is transverse to the support surface and points towards the support surface, because the user can then perform a downward pressing motion. It is an additional advantage that the user does not need to actively lock the adjusting screw, but the system locks the adjusting screw automatically.

[0027] Preferably, the protrusion, the locking recess and the locking spring are configured in use together to lock the locking head rotationally when the locking recess receives the protrusion and a rotational force exerted on the locking head is smaller than a threshold value, and the protrusion, the locking recess and the locking spring are configured in use together to move the locking head to the first locking element position when a rotational force exerted on the locking head is greater than the threshold value.

[0028] It is an advantage of the present invention that it protects against an unintentional adjustment of the height, and simultaneously simplifies releasing the lock to rotate the adjusting screw. The user can release the lock with the tool used to rotate the adjusting screw, without first pushing in the locking head. This is a more intuitive movement in relation to the use of an adjusting screw than relative to first pressing the locking head, so that a user with less prior knowledge can use the system in a correct manner. This extends the service life of the tool, the locking head, and the device.

[0029] Preferably, the at least one protrusion extends between a first protrusion edge and a second protrusion edge, wherein the first protrusion edge and the second protrusion edge are transverse to the direction of rotation of the locking head. The first protrusion edge and the second protrusion edge are inclined relative to the locking head, with an angle of inclination of at most 45°, preferably between 15° and 45°, more preferably between 20° and 40°. The locking recess has a shape complementary to the at least one protrusion, comprising a first locking recess edge and a second locking recess edge transverse to the direction of rotation of the locking head.

[0030] Preferably, the at least one protrusion is non-circularly symmetric relative to the axis of rotation of the locking head, and locks the locking head when the adjusting screw is in a first rotational position relative to the sleeve.

[0031] Optionally, the protrusion and the locking recess are configured in use together to enable the locking head to move to the second locking element position when the locking head is in a second rotational position relative to the screw cage.

[0032] It is an advantage of the present invention that the automatic locking takes place when the locking head and adjusting screw are in a predetermined position. This simplifies and speeds up the height setting, while the device is secured against unintentionally changing the height.

[0033] Preferably, the height adjuster comprises a height indicator, configured in use to display an indication of a distance between the slat and the slatted base frame according to the height direction. The height indicator preferably comprises a flexible indicator strip, an indicator guide provided with an indicator guide slot, and a first indicator window. The indicator strip comprises indicator markings. The screw cage and the locking cover comprise the indicator guide, the indicator guide slot receives the indicator strip with indicator markings facing the cover surface, and the first indicator window is a transparent part of the cover surface, preferably a third through-hole, aligned with the indicator guide slot. The indicator strip is connected to the sleeve, preferably by a pin with a flat head, which is received through a through-hole in the indicator strip into a hole in the sleeve. The hole in the sleeve clamps the pin. The indicator may also be connected to the sleeve by any other way known in the prior art. The indicator strip is configured in use to slide back and forth in the indicator guide slot when a distance between the slat and the slatted base frame according to the height direction changes.

[0034] It is an advantage of the present invention that it simplifies the setting of the device, because a user can easily read the set height. It is an additional advantage of the present invention, in particular when the head is transverse to the support surface and points towards the support surface, that the indicator markings are directed towards the support surface and are readable through a window.

[0035] Preferably, the device further comprises a flex head, which comprises a flex head surface and two slat holders. The slat holders are provided to each receive one of two co-aligned slats, and are connected to the flex head surface on opposite sides of the flex head surface. The flex head is provided to be connected to the height adjuster, preferably by a snap connection.

[0036] It is an advantage of the present invention that a slatted base based on this device can easily be constructed, as the actions of connecting the device to the slatted base and connecting the slats to the device can easily be performed independently of each other, for example first connecting the device to the slatted base and only then connecting the slats to the device.

[0037] The flex head surface is preferably directed along the support surface and configured in use to be located on the same side of the bearing surface as the second adjusting screw end when the flex head is connected to the height adjuster. Preferably, the flex head surface comprises a fourth through-hole, which is aligned with the second adjusting screw end.

[0038] It is an advantage of the present invention, in particular when the head is transverse to the support surface and points towards the support surface, that the adjusting screw remains accessible after the flex head is mounted on the height adjuster.

[0039] Preferably, the adjusting screw is configured in use to adjust a distance between the slat and the slatted base frame according to a value from a slatted base height profile, preferably an Ergosleep ®< Sleep DNA ®< , when the adjusting screw is in the first rotational position relative to the sleeve. For example, there exists a device in which it is possible to adjust a distance between the slat and the slatted base frame according to all four standard height settings used in an Ergosleep ®< Sleep DNA ®< , for example, there exists a device in which it is possible to adjust a distance between the slat and the slatted base frame according to three of the four standard height settings used in an Ergosleep ®< Sleep DNA ®< .

[0040] It is an advantage of the present invention that it enables setting according to an Ergosleep ®< Sleep DNA ®< .

[0041] Preferably, the distance between the slat and the slatted base frame changes by the difference in distance between two successive, standard height settings used in an Ergosleep ®< Sleep DNA ®< upon a movement of the adjusting screw relative to the sleeve equal to the pitch. As a result, upon a full revolution, a movement is made from a first standard height setting used in an Ergosleep ®< Sleep DNA ®< to a subsequent height setting used in an Ergosleep ®< Sleep DNA ®< .

[0042] Preferably, the indicator markings comprise a coding that corresponds to a coding of a height setting from a slatted base height profile, preferably the Ergosleep ®< Sleep DNA ®< color coding.

[0043] It is an advantage of the present invention that it simplifies setting according to an Ergosleep ®< Sleep DNA ®< . In particular, when the locking mechanism locks the adjusting screw at the standard height settings used in an Ergosleep ®< Sleep DNA ®< , the setting is further simplified. It is an additional advantage of the present invention that uncertainty about the correct setting is reduced.

[0044] The present invention further provides a height adjuster for adjusting the height of a support surface of seating or lying furniture with a furniture frame, such as for example a bed, wherein the support surface is for example formed by a slat of a slatted base. The support surface may be divided into different zones that can be adjusted in height separately by different height adjusters according to the present invention.

[0045] The height adjuster is provided to connect the support surface to the furniture frame and is configured in use to set a distance between the support surface and the furniture frame according to a height direction transverse to the support surface. The height adjuster comprises an adjusting screw and a sleeve, which is preferably tubular. The adjusting screw is provided to be connected to the support surface and the sleeve is provided to be connected to the furniture frame. The adjusting screw is rotationally, preferably threadedly, connected to the sleeve and the movement of the adjusting screw relative to the sleeve is configured in use to change the distance between the support surface and the furniture frame according to the height direction.

[0046] Preferably, the adjusting screw and the sleeve are configured in use together to move the adjusting screw linearly relative to the sleeve when the adjusting screw rotates.

[0047] Preferably, the adjusting screw comprises a first adjusting screw end, a second adjusting screw end, a head having a first engagement point, and a shank having a screw thread having a pitch, as previously described in the present invention.

[0048] It is an advantage of the present invention that adjusting the height of a support surface is simplified. It is an additional advantage that a screwdriver or other tool can be used when setting the height, whereby the required force can be reduced through leverage and the accuracy of the height setting can be increased. Furthermore, the force transmission from the hand of the person setting the height can be controlled more easily. It is an additional advantage that, through the use of an adjusting screw, the height adjustment does not require any parts to be disassembled, which leads to a further simplification of the adjustment of the height of a support surface. Furthermore, the risk of damage resulting from the disassembly of parts during height adjustment is lowered.
