Description
Lifting Apparatus
The present application relates to a lifting apparatus for a bed and a method of use of said apparatus.
Although the following description disclo ses a device for lifting a bed, it will be appreciated by those skilled in the art that the present invention can be used to lift or raise other furniture whilst keeping the same substantially level or stationary in respect to the horizontal axis.
It is a recognised problem that beds occupy a large amount o f floor space in the average home. As the co st of accommodation and housing increases, usable floor space is at a premium and a number of methods of enabling the use of the floor space taken up by a bed have been disclosed. Traditionally, fold-down beds are utilised to make floor space available when the bed is not in use. However, the main disadvantage to a fold-down bed is that the bedding and any other items placed on the bed have to be removed as the bed is moved from a horizontal in-use position to the substantially vertical storage position. In addition, when stored, the bed takes up space adjacent to a wall which could otherwise be used for decoration, additional storage and/or the like.
Apparatuses which raise beds whilst the bed remains sub stantially level or in a horizontal orientation have been disclo sed. However, these apparatuses use counterbalanced weights to offset the weight of the bed. This is a particular disadvantage as the weights are heavy and therefore difficult and expensive to transport. This problem is exacerbated because the majority of these apparatuses are used in city centre hotel rooms, apartments and flats, where floor space is most
expensive. As such, the weights have to be transported up a number of floors which increases installation time and costs, as well as including the risk of injury to the installers.
It is therefore an aim of the present invention to provide an apparatus which addresses the aforementioned problems.

The present invention addresses the problem of making the floor space underneath a bed available when the bed is not in use. The invention provides an apparatus which raises the bed from the in use po sition to a storage position at, and/or adjacent to the ceiling or roof of the room in which the bed is located. It is envisaged that this invention will have particular application where floor space is most expensive, for example in inner city apartments and/or the like. Advantageously, when compared to the prior art, the present invention is much simplified as it does not use counterweights or counterbalances therefore installation and maintenance is much safer, quicker and less expensive. Indeed, the system as a whole is much safer, quicker and less expensive compared to prior art examples.
Turning now to figure 1 which shows side (a), front (b) and plan (c), cross sectional views of the apparatus 2 in the first, 'in use'
position. The apparatus includes a support means or platform 4 on which a mattress 6 is placed, and on which a user lies when in the in use po sition. The apparatus also includes a pair of upright or substantially vertical recesses or channels 8a, 8b which are attached to a wall 10 in this example. However, if the bed frame is to be fastened to a stud partition that is of a light construction, for example a thin metal stud system designed only to create a dividing wall, the metal recesses or channels 8a, 8b are securely fastened to the floor and ceiling joists, or if the ceiling is formed by a concrete floor above they will extend the channels and include an adjustable right angled bracket, suitable in strength, the will be bolted to the floor and ceiling joists.
The platform 4 is essentially a frame comprising a number of linear frame members. The outer frame members 9a-c form a square in this example and are made of relatively lightweight metal. The inner frame members 1 1 are typically wooded slats on which the mattress is supported. The slats are positioned to lie substantially in the same plane as the outer frame members 9a-c, bridging between members 9a and 9c, to form a sub stantially flat platform on which the mattress 6 lies. It will be appreciated by persons skilled in the art that further frame members could be incorporated to form a complete bed structure. However, this example is substantially lighter in comparison.
First portions 12', 12" of the platform 4 are located within the channels 8a, 8b and span horizontally across from one channel to the other, one portion located above the other. Second portions 14a, 14b of the platform vertically span the first portions, securing the same together. It is only the cantilevered contact between the channels 8a, 8b and the first portions 12', 12" which keeps the platform (and therefore the mattress) level or horizontal.
It is intended that users will only be supported on the platform 4 when the same is in the in use po sition. When the bed is to be raised, the person alights so as not to place undue strain on the motor 1 6. The mattress, bed, bedding and other articles can remain on the bed. In conventional systems any change in bedding or mattress weight has to be taken into account and the counterweights rebalanced.
In this example a foot 26 is placed at the distal or unsupported end of the platform to support the additional weight of one or more persons using the bed. The leg 26 is foldable and can be folded to a storage position when the platform is raised, as shown in figure 2.
Figure 2 shows side (a), front (b) and plan (c), cross sectional views of the apparatus 2 in the second storage position. In this position the platform 4 is stored in, or adjacent to the ceiling (not shown) of the room in which the bed is located.
The platform 4 is raised by a motor 16 and pulley 1 8 system. The motor is attached to a shaft or spindle 20 which has pulleys 22a, 22b axially po sitioned thereon. The motor in this example is a 24 volt motor which can run off domestic electricity supplies. The pulleys 22a, 22b are po sitioned such that they are located at the top of each channel 8a, 8b. Cable 24 runs in the channels 8a, 8b and is attached at one end to the first portions 12', 12" of the frame members. The cable 24 is wound or unwound around the pulleys by the motor rotating said shaft or spindle 20 and therefore the pulleys. Thus it is the cable 24 attached to the platform 4 and the tension in the same, controlled by the motor 16 which raises the platform 4 and the bed. In addition, it is the force between the first portions 12',
platform level during this movement. In this example the platform is raised and lowered between the first and second positions by using a motor and/or gearing which allows the shaft or spindle 20 to be rotated in either direction about its longitudinal axis. Therefore, the bed/mattress 6 is horizontally raised or lowered depending on the direction of rotation.
It should be further noted that the apparatus can be operated without counterbalance or counterweights, thus simplifying the apparatus.
It will be appreciated by persons skilled in the art that the apparatus can be decorated to fit in with the surroundings in which it is situated. For example the bottom of the platform and/or the channels can have decorated inserts which improve the appearance of the apparatus and/or are sympathetic to the room in which it is located.
Turning to figure 3 where there is shown a perspective view of the right corner of the apparatus. In this example, the platform 4 includes an additional frame member 30 which lies parallel to frame member 9b and the ends of which are attached to frame members 9a and 9c. The frame members are attached to the first portions 12', 12", the ends of which are located in and engage with the channels 8a, 8b. Located at the top of the apparatus is the motor 16 which is attached to the spindle 20 and the pulley or winding wheel 22b. In use the cable 24 is attached at one end to the pulley wheel 22b and the other end is attached to the platform 4 via the second pulley wheel 32 located towards the foot of channel 8b. In this embodiment the motor 1 6 powers movement in both the upwards and downwards directions. The frictional forces between the first portions 12 and the channels 8 are sufficient to hold the platform in place should the cable 24 or motor 16 fail.
Typically the motor is an AC motor with worm/wheel reduction. For application in the UK the motor specifications are typically; 230V 350Hz with 2 Amps producing a motor power of 0.37 KW. In this particular example the output torque is 150Nm with an output speed of 17 rev/min. As a result the time taken for the bed to rise or fall is usually approximately ten seconds.
The main benefits of the present invention are that the whole system can be installed and assembled using only two people in a standard size room (ceiling height of 2.4 m) . In addition, the system can be easily transported through domestic premises and is assembled on site. The factory set weight lift limit to prevent overload of the motor provides an additional element of safety and the system is easy to install into any type of room and the can be plugged into a domestic electricity supply.
Although it is envisaged that the present system will be predominately used for beds it is anticipated that other items could be lifted such as model train sets, tables including dressing tables or other uses where a need to create a dual space would be required.
