SE523726C2 - Bed moving device, comprises boxes containing spring loaded drums with pull cords for securing to foot end of bed - Google Patents

Abstract

The device comprises a number of roller boxes each of which comprises a casing (1) containing a spring-loaded drum (4) with a pull cord (2) wound around it. The device is preferably secured to the underside of the bed at its foot end (8) using a bayonette coupling. A second device (12) can also be secured to the head end (9) of the bed.

Description

'ur-o 5 2 3 7 2 6; :: = j; US 3745597 describes a device especially for hotel beds for facilitating cleaning and bedding. The bed is equipped with an extra leg placed in the center of the bottom of the bed and equipped with wheels. Under the bed is placed a drawer with a sloping top with a groove that ends with a recess. A stationary handle is arranged at the front edge of the bed. When cleaning and making the bed, the user grabs the handle and pulls the bed towards him. This means that the wheel on the centrally located extra leg runs along the groove on the top of the box.

When the wheel reaches the end of the track, the wheel slides down into the recess, whereby the bed can be made with the person standing on only one side without moving. The device lacks a pull-out handle and does not allow a work position that is clumsy from a load point of view.

A construction which facilitates the movement of beds without obtaining an unobtrusive load on the back is known from US 2862213. The patent describes a device which lifts the bed vertically and moves the bed horizontally in the room. The device, which is mounted under the bed frame, is operated by means of two pedals. By pressing one of the pedals, the bed is raised at the same time as it runs along a path in a substantially horizontal direction. When the second pedal is pressed, the bed is raised while at the same time it runs mainly horizontally back to the original position. The construction is technically complicated and lacks a pull-out handle. US 3982613 describes a wheeled bag with a towing device. The towing device consists of a rope, chain or strap that is pulled out or wound on a spring-loaded mold box mounted inside the bag. In use, the rope, chain or belt is pulled out until the rope, chain or belt is completely pulled out of the winding device. Then the bag is moved.

After the transfer is completed, the line is automatically pulled into the roller device. Nowhere in the patent specification is the use of the towing device mentioned when moving, for example, a bed in connection with cleaning and bedding. In addition, the construction has the weakness that it easily overturns caused by the roller box being mounted in a less favorable place in relation to the center of gravity of the bag.

Existing devices for moving beds differ from the invention in that they lack a pull-out handle among the arm. Furthermore, those who move a bed with known technology cannot move a bed without risking a work-poor position for the back. Description of the invention The invention comprises a device or rather an aid for temporarily moving objects and preferably beds. The aid is especially compulsory to use in hotels and other types of accommodation with many beds.

A vital part of the invention is a replaceable cassette, hereinafter referred to as a roll box, which in principle consists of known devices such as winders for cables, hoses, wire, chains and ropes.

Hereinafter, said elongate components are collectively referred to as tow line.

Characteristic of winds is that the towline is connected to a resilient coupling. That is, after the towline has been pulled out of the casing of the roll box, the spring suspension manages to automatically wind the towline back into the housing after the towline has been used.

The towline has a handle at its end which helps to ensure that the towline is always easily accessible.

Since the tow line is automatically returned to the roller box after use by resilience, a stop is required. Such a stop is provided by the handle of the towline. Thus, the handle can be caught by, for example, a ring which is traversed by the tow line. This ring or loop can be an addition to the cassette or mounted on the headboard of the bed.

With reference to Figures 1-4, the invention will be described in more detail.

Fig. 1 shows a sketch of the aid in the form of a cassette and seen from the side. Fig. 2 shows the tow line pulled out from the container or box of the roll box.

Fig. 3 shows the aid fixed under a foot end of a bed and with the towline pulled out. Fig. 4 shows a first aid fixed under a foot end of a bed and with the towline extended and a second aid mounted on the end side of the bed for the head and showing how a tow rope passes through a pulley on a wall The aid (roller box) comprises a cover e 1 which contains a tow line 2 which ends with a handle 3. The tow line and other materials which are included in the invention must be made of materials which do not have a detrimental effect on the environment. Thus, the towline should preferably be made of natural materials, such as flax or hemp. Of synthetic materials can be used nylon and fi bres of e.g. polyethylene. As an alternative, the towline can be made of steel wire that is twisted into a wire. The roller box cover and the pull rope handle can advantageously be made of recyclable plastic. 523 726 4 The tow rope is alternately enclosed inside the housing and connected to a spring-loaded drum 4, which means that the tow rope or a pull-out of a bed is automatically wound back onto the drum.

The cover is provided with brackets 5 with which the rolling box 6 of the aid can be connected to the lower part 7 of the beds and in the first place to the foot end 8 of the bed.

A characteristic part of the invention is that the roller box of the aid can easily be replaced by some type of quick coupling, e.g. with a baj oneconnection.

The aids described above are used to move the bed from its regular place.

Usually this means that the bed in its initial position stands with its headboard 9 pressed against a wall 10. In other words, it is important to move the bed from a wall, which is demonstrated by the arrow 11.

To pull out the bed according to the invention, the user first grips the handle (3) and then pulls out the tow line in its entire length from the roller box (6). Characteristic of the invention is that the aid line's tow line is in its length fl visible and that the aid line's tow line can in relation to the aid's attachment curlct in the bed form choices fi at angles in relation to the bed's footboard.

After the bed has been moved backwards (indicated by the arrow 11 in fi g. 3) and the user releases the handle, this results in the tow line being automatically wound back on the roller box drum.

Described use of the ceiling and for extension from the wall can also be used to move the bed obliquely backwards or sideways.

In order to restore the bed's original position in an ergonomically best way, a second aid 12 can also be placed under the headboard (9) of the bed, according to the invention.

To be able to move the bed back against the wall (shown by arrow 13 in fi g. 4), a loop or pulley 14 is mounted on the wall or on the floor. As shown by fi g. 4, the tow line 15 passes through the pulley on the wall. From the pulley, the towline runs on to the foot end of the bed, where the towline's handle 16 is again used.

Advantages of the invention When applying the invention, a number of advantages are achieved. In general, it can be said that the work of making beds is facilitated by the cleaning staff not having to bend over to move the bed. «I» a | 5 2 '7 7 9 6 _.- _ ... . .. u .. .. n .. ... -. a -u a »1 w s. o I i 'i a * _ I.,' 2.'I I !! 3.2 23.! ! 2.1.2 '{v n s. u a a. u n o n c o a 0 u n a n 1 nu un I vv I 0 i) With the help of the exercise, the user can stand straight when working to move the bed straight back, obliquely to the side or sideways. With the help of the invention, such a tiring work step is also facilitated to move the bed back to its original place. Therefore, harmful physical loads can practically be avoided, which can lead to problems with, among other things, the lumbar spine and As a result of incorrect working position, disc herniation and back shots can occur in the worst case.

Furthermore, injuries to the neck, arms and shoulders can be avoided when using the invention.

In any case, the frequency of the currently common occupational injuries of e.g.

Cleaning staff.

Another advantage is that vital parts of the invention are already on the market and which conditions prices make the aid relatively cheap to manufacture.

A further advantage of the invention is that it is easy to replace the roller box of the aid due to the fact that it is attached to a construction with a bayonet socket.
