Description
-1- A Mattress Lifting Device
Field of the Invention
The present invention relates to a device for lifting a mattress.
Background
Many bedding arrangements comprise a mattress supported by a mattress support, usually in the form of a bed base. Usually a fitted sheet will be placed over the mattress. In order to properly fit or tuck in the sheet, the mattress is usually lifted at each corner. Some people have difficulty in lifting the mattress. US patent 7581270 describes a type of mattress lifting device that has a stationary member and a pivoting lifting member, both of which are inserted from the side of the bed between the mattress and the bed support. The lifting member uses one end of the lifting member to receive a downward force and the other end to lift the mattress. This mattress lifting device suffers from the problems as the end of the lifting device is doing the lifting, which can damage the mattress. Furthermore, many bed supports have a lip for keeping the mattress on the bed support. In such cases the lip will prevent this device from being inserted between the mattress and the support. Additionally the actuating end of the lifting member projects from the side of the bed, which is undesirable.
The present invention seeks to provide an alternative mattress lifting device.

Detailed Description of Embodiments
Referring to Figure 1 to 4, there is shown a mattress lifting device 10 which comprises a mounting member 20 and a lifting member 12. The lifting member 12 comprises an elongate member 14 and a lifting plate 32 for lifting a mattress 100. The elongate member 14 is pivotally connected to the mounting member 20 by pivotal connection 16. The mounting member 12 comprises a mounting plate 70 for attaching to a mattress support 102. The lifting member 12 comprises an actuator 18 for pivoting the elongate member 14 and for causing the lifting plate 32 to lift the mattress 100 when actuated. The lifting plate 32 pivots with respect to the elongate member 14 as it lifts the mattress 100 and as such substantially all of the upper surface of the lifting plate 32 remains in contact with the mattress 100 whereby the lifting plate 32 provides a distributed lifting force to the mattress 100.
The mounting plate 70 is positioned on a top surface of the mattress support 102, inwardly from a side rail 106 of the mattress support. It can be seen that the bottom surface of the mattress 100 and the top surface of the mattress support 102 are below the top surface 108 of the side rail 106. The mounting plate 70 is provided with a plurality of holes 90 there through for receiving fasteners, such as screws 104, for fixing the plate 70 to the supports 102. Generally the supports 102 are slats formed of spaced apart wooden beams. The mounting plate 70 is configured to rest on two of the spaced apart beams 102. In operation the plate 70 will apply a downward force to the mattress support 102 in response the actuation of the lifting member 12. -5- ln an example form the mounting plate is a 220mm x 80mm x 2.0mm flat steel plate. In an example form the lifting plate is a 220mm x 180mm, 2.0mm steel plate.
The elongate member 14 is disposed between and underneath the spaced apart beams 102 of the mattress support. In an example form the elongate member 14 is 16mm square hollow section steel tubing.
In an embodiment the elongate member 12 is pivotally connected midway about its length such that a portion 52 of the member 12 is on the lifting plate side of pivotal connection 16 and a portion 54 is on the actuator 18 side of the pivotal connection 16. The length of the portion 52 may be determined by the distance that it is desired for the mattress 100 to be lifted and the distance inward from the side of the mattress where the lifting will occur. The length of portion 54 may be determined by the position of the actuator 18 relative to the side rail 106 of the bed. The relative lengths of portions 52 and 54 may be selected according to the amount of leverage desired.
In an embodiment the actuator 18 is in the form of a pedal pivotally suspended from an end 58 of the elongate member portion 54 by stirrups 56. The pedal 18 is disposed to be between and below the spaced apart beams 102 of the mattress support. In an embodiment the actuator 18 is disposed substantially underneath a side rail 106 of the mattress support.
In an embodiment the distance between the mounting plate 70 and the elongate member 14 can be altered by an adjustment means so that the elongate member portion 54 has adequate clearance from a bottom surface 110 of the side rail 106.The side rail is shown in phantom in Figure 4. The adjustment means in this embodiment comprises a threaded bolt 72 pivotally coupled to the elongate member 14 and an internally threaded socket 80. The mounting means 20 also comprises a web 76 extending between an edge of the plate 70 and the lower end of the socket 78. The mounting member 20 further comprises a locator 78 for locating a track 30 in position.
In an embodiment the distance between the lifting plate 32 and the elongate member 52 can be altered by an adjustment means so that the elongate member portion 54 has adequate clearance from the support beams 102. The adjustment means in this embodiment comprises a threaded bolt 42 coupled to a pivot device 40 for engaging the -6- lifting plate 32. The adjustment means further comprises an internally threaded socket 44 connected to an end of the elongate member potion 52. In this embodiment the pivot device is a wheel 40 axially mounted to the bolt 42. The wheel 40 travels within the track 30 on the underside and along a centre line of the plate 32. Mounting member 20 also comprises a web 76 extending between an edge of the plate 70 and the lower end of the socket 78.
In an embodiment the device comprises a biasing means in the form of a spring 46 that extends between the plate 32 and the elongate member portion 52. The spring 46 is attached to the elongate member portion 54 closer to the pivot point 16 than to the end with the wheel 40. The spring 46 is attached to the lifting plate 32 distally from the initial point of contact of the wheel 40 with the track 30 relative to the position of the wheel 40 when the device 10 is actuated. The spring 46 is configured to urge plate 32 closer to the elongate member portion 52. This in turn urges the wheel 40 to remain in engagement with the track 30 when the lifting force is removed from the actuator 18. A magnet 60 may be provided on the elongate member 14 so that the pedal 18 can be secured out of the way. When desired for use the pedal 18 can be detached from the magnet 60 and swung down as indicated by arrow D in Figure 1 ready for use.
The method of operation of this embodiment of the device 10 will be described with reference to Figure 5.
Usually a device 10 will be installed in the vicinity of each corner of the mattress support for lifting the respective corner area of the mattress. In use the elongate member 14 may be substantially horizontal initially.
When it is desired to lift the mattress 100, such as to apply a fitted sheet, the user can operate the actuator 18, such as by removing the pedal 18 from the magnet 60, placing their foot between the stirrups 56 and pushing down on the pedal 18 as indicated by arrow A. This will cause the elongate member portion 54 to pivot about the pivot point in a downwardly direction. This will also case the elongate member portion 52 to pivot about the pivot point 16 in an upwardly direction. The downward force applied to the pivot point 16 will be transferred to the mounting plate 70 and then to the support beams 102. -7-
As the elongate member portion 52 pivots it will move in an arc as indicated by arrow B. The wheel 40 will move in an arc as well, initially mostly in an upwardly direction which will lift the lifting plate 32, which in turn will lift the mattress 100 as indicated by arrows C. As this wheel 40 moves through the arc, it also moves along the track 30. This allows greater lifting than if the member 14 was merely pivotally connected to lifting plate 32 as is the case in the embodiment of Figure 6.
Further as the elongate member portion 52 pivots the spring 46 is stretched.
When it is desired to lower the lifted mattress 100, the user can release the downward force on the actuator 18. The weight of the mattress 100 will urge the elongate member portion 52 to pivot back to its rest position, as will the resilience of the spring 46. In doing so, the wheel 40 will roll down the track 30. The elongate member portion 54 will rise and return to its rest position.
Figure 6 shows an alternative embodiment of a mattress lifting device 200, which comprises of a mounting member 20 and a lifting member 12. The lifting member 12 comprises an elongate member 14 and a lifting plate 32 for lifting a mattress. The elongate member 14 is pivotally connected to the lifting member 12 by pivotal connection 16. The mounting member 12 comprises a mounting plate for attaching to a mattress support. The lifting member 12 comprising an actuator 118 for pivoting the elongate member 14 and for causing the lifting plate 32 to lift the mattress when actuated. The lifting plate pivots with respect to the elongate member 14 at pivot point 216 as it lifts the mattress and as such substantially all of the upper surface of the lifting plate 32 remains in contact with the mattress 100 whereby the lifting plate 32 provides a disbursed lifting force to the mattress 100.
The mounting plate 70 is positioned on a top surface of the mattress support in a similar manner to the previous embodiment. The elongate member 14 is disposed between and underneath the spaced apart beams 102 of the mattress support.
In this embodiment the elongate member 14 is Z shaped and is pivotally connected at one of the corners of the Z shape to the mounting member 20. In an embodiment the actuator is in the form of a leg portion 118 of the Z shape and a pedal 18 is able to slide out from the leg 118. A return spring 170 may be used to return the pedal 18. The connection 154 -8- between the legs 152 and 118 of the Z shape is generally perpendicular to the legs 152 and 118.
In an embodiment the distance between the mounting plate 70 and the elongate member 14 can be altered by an adjustment means in a similar manner to that described in the previous embodiment.
In an embodiment the distance between the lifting plate 32 and the leg 152 can be altered by an adjustment means so that the leg 152 has adequate clearance from a bottom surface of the mattress support. The adjustment means comprises a threaded bolt 142 pivotally coupled to the end 144 of the leg 152 and an internally threaded socket 143.
When it is desired to lift the mattress 100 using device 200, the user can operate the actuator 118 by placing their foot on the pedal 18 and pushing down on the pedal 18. This will cause the elongate member 14 to pivot about the pivot point 16. As such the leg 152 will move in an upwardly direction. The downward force applied to the pivot point will be transferred to the mounting plate 70 and then to the support beams.
As the end 144 of elongate member 14 pivots, is will move in an arc that lifts the lifting plate 32, which in turn will lift the mattress 100. As the lifting plate 32 it will pivot about pivot point 216 thereby substantially maintaining contact with the mattress so as to distribute the lifting force across substantially all of the upper face of the lifting plate 32.
When it is desired to lower the lifted mattress 100, the user can release the downward force on the actuator 118. The weight of the mattress 100 will urge the elongate member 14 to pivot back to its rest position.
Figure 7 shows a further embodiment of a mattress lifting device 300, which comprises a mounting member 302 and a lifting member 304. The lifting member 304 comprises an elongate member 306, a lifting plate 308 for lifting a mattress, and a support member 310. The mounting member 302 comprises a support member 312 and a mounting plate 314 for attaching to a mattress support. The lifting member 304 is pivotally connected to the mounting member 302 at a distal end 316. The lifting member 304 comprises an actuator 318 for pivoting the elongate member 306 and for causing the lifting plate 308 to lift the mattress when actuated. The lifting plate 308 pivots with respect to the elongate member 306 at a distal end 320 of support member 310 as it lifts the mattress and as such -9- substantially all of the upper surface of the lifting plate 308 remains in contact with the mattress, whereby the lifting plate 308 provides a disbursed lifting force to the mattress.
In an embodiment, the support members 310 and 312 contain a plurality of holes to which the lifting plate 308 and the mounting plate 314 may be attached to with a fastener. In this example, they are fastened together using bolts or pins secured with circlips. The plurality of holes located in the support members 310 and 312 allow the distance between the lifting plate 308 and the mounting plate 314 to be adjusted.
In an embodiment, the distance in which the mattress is lifted is limited by a linkage arm 322. The linkage arm 322 is pivotally connected to the support members 310 and 312 at a pair of points 324 and 326. The point 324 and 326 are located where the support members 310 and 312 are attached to the lifting plate 308 and the mounting plate 314. It would be appreciated by a person skilled in the art that the linkage arm 322 need not necessarily be connected to the support members 310 and 312 at the points where they are attached to the lifting plate 308 and the mounting plate 314. As such, the linkage arm 322 may be pivotably connected to any of the holes located in the support members 310 and 312.
In an embodiment, the linkage arm 322 has a slot 328 which connects to the support member 310. The slot 328 allows the linkage arm 322 to pivotably and slidingly connect to the support member 310.
In this embodiment an elongate member portion 330 is downwardly bent at a median point 332 between the distal ends 316 and 320 at an angle of 30 e to the horizontal.
When it is desired to lift the mattress 100 using device 300, the user can operate the actuator 118 by placing their foot on the pedal 318 and pushing down on the pedal 318. This will cause the elongate member portion 332 to pivot about the distal end 316 in a downwardly direction. This will also cause the elongate member portion 330 to pivot about the distal end 316 in an upwardly direction. The downward force applied to the distal end 316 will be transferred to the mounting plate 314 and then to the support beams.
As the end 320 of elongate member 306 pivots, it will move in an arc that lifts the lifting plate 308, which in turn will lift the mattress 100. The lifting plate 308 will pivot about the 2015205903 23 Μ 2015 -10- distal end 320 thereby substantially maintaining contact with the mattress so to distribute the lifting force across substantially all of the upper face of the lifting plate 308.
When it is desired to lower the lifted mattress 100, the user can release the downward 5 force on the actuator 318. The weight of the mattress 100 will urge the elongate member 306 to pivot back to its rest position.
The present invention provides advantages over the prior art in that it is less inclined to damage the mattress because the lifting force is distributed over the surface of the lifting 10 plate and the user can actuate the device with their foot leaving their hands free to tuck in the sheet.
Modifications and variations may be made to the present invention with the context of that described and shown in the drawings. Such modifications as will be apparent to the 15 skilled addressee are intended to fall within the scope of the present invention.
