The invention relates to a device for receiving, transporting and storing pieces of furniture, comprising a movable support rack and comprising a lifting apparatus fastened to the movable support rack, wherein it is possible to lift a first piece of furniture using the lifting apparatus such that a second piece of furniture can be arranged below the first piece of furniture that has been lifted by the lifting apparatus.
It is known from practice that pieces of furniture, such as chairs or tables which are not permanently required in a location, are transported on and optionally stored in transport apparatuses until the pieces of furniture are required again and are put in place at the intended location. One example of this are stackable chairs in an events hall, which, as required, are set out in the events hall for the event in question and are then put away again and stored in a storeroom so that the events hall can be used for other purposes. The chairs and tables can be rapidly and easily transported using a sack barrow, for example.
Movable trolleys are also known on which stacked chairs or tables can be stored and stowed away. Arranging and storing a plurality of pieces of furniture in a space-saving manner on a sack barrow or a trolley of this kind requires the pieces of furniture in question to be stackable, however. Very heavy or non-stackable pieces of furniture cannot be stored and stowed away in a space-saving manner using the trolleys known from practice.
From practice, movable workshop cranes are also known using which very heavy objects, such as car engines or also very heavy pieces of furniture, as the case may be, could be lifted. Workshop cranes of this kind are, however, unsuitable for arranging and transporting more than one very heavy piece of furniture one on top of the other.
It is desirable to design a device such that this device can be used to rapidly and easily arrange and transport at least two possibly heavy pieces of furniture one on top of the other.
According to an aspect of the invention a movable support rack comprises a locking apparatus for locking the second piece of furniture on or in the movable support rack.
The movable support rack expediently has the largest possible usable interior space, in which a piece of furniture can be arranged such that the movable support rack surrounds the piece of furniture. By configuring the device in this way, a first piece of furniture can be rapidly and easily arranged within the support rack and lifted by means of the lifting apparatus, such that a second piece of furniture can be arranged below the first piece of furniture. To arrange these two pieces of furniture in this way, only one area of floor space is therefore required, which corresponds to one of the two pieces of furniture or to the larger of the two pieces of furniture. If the second piece of furniture comprises furniture transport rollers, the second piece of furniture can be moved and stored by being locked in or on the support rack together with the lifted first piece of furniture by means of the device according to the invention, which increases the efficiency when transporting the pieces of furniture.
The device makes it possible to store a plurality of pieces of furniture one above the other and, as a consequence, to store a plurality of pieces of furniture within a comparatively small floor space without complex structural measures being required in a storage space. The movable support rack is expediently intended and accordingly configured for receiving high loads or for receiving heavy pieces of furniture. The lifting apparatus may be designed and configured such that even heavy or bulky pieces of furniture can be picked up and lifted using the lifting apparatus by a single user.

In order to make it easier to receive the pieces of furniture, it is provided that the at least two engagement elements are pivotally mounted on the associated guide rail. Preferably, engagement elements of this kind are designed as angular support elements that project from the guide rail. The engagement elements may be configured to be spring-loaded, such that they are pivoted upwards when a load is not supported on the relevant engagement element. Preferably, the pivotable engagement elements comprise an abutment, such that said elements cannot be pivoted downwards to any extent desired and can be fixed in a horizontal orientation, for example, in order to be able to hold and lift a piece of furniture.
In order to configure the device for use with a plurality of pieces of furniture, it is advantageously provided that the device comprises at least two separately operable groups of at least two engagement elements, such that the device can lift at least two pieces of furniture. When the device is configured in this way, the at least two groups of engagement elements can advantageously be operated independently of one another using just one drive apparatus. In an alternative configuration of the concept of the invention, the at least two groups of engagement elements can be operated using the associated drive apparatus. In particular, when linear drives are used, each individual engagement element can be operated by an associated drive apparatus. In such a configuration of the concept of the invention, the at least two engagement elements associated with the group can be operated together.
In order to configure the device to be operable independently, it is advantageously provided that the device comprises an energy storage device for operating, the drive apparatus. In this way, the drive apparatus may for example comprise a rechargeable battery or a compressed-air tank.
In order to protect the pieces of furniture that can be transported and optionally stored in the device against environmental influences, is preferably provided that the device comprises outer cladding that surrounds the device or the movable support rack in regions. It is also possibly and optionally provided, according to the invention, that the receiving opening made on the front side of the device is designed to be closed by double doors articulated to the sides of the support rack, or by a roller shutter.
It is preferably provided that the device is adapted for use for hospital beds. The device may be constructed such that the support rack is designed, in terms of its dimensions and the maximum permissible load, for receiving hospital beds and the lifting apparatus is designed for lifting hospital beds. Advantageously, the device can be rapidly and easily cleaned, in order to also satisfy strict hygiene regulations in hospitals. It is also possibly and optionally provided, according to the invention, that the device does not comprise any highly combustible components or is equipped with additional fire retardants in order to fulfil fire regulations in hospitals.
In order to make it possible to transport the device comprising two hospital beds received therein on hospital premises so as to be unimpeded as far as possible and to store said device in storage rooms, which are often in the basement, according to an advantageous configuration of the concept of the invention, it is provided that the device does not exceed a maximum height of 1.9 metres, a maximum width of 1.1 metres and a maximum length of 2.3 metres.
In order to make it possible to disinfect or decontaminate pieces of furniture that are contaminated with pathogenic germs or are infected with pests within the device, according to an advantageous configuration of the concept of the invention, it is provided that the device comprises a cover that sealingly surrounds the usable space in the device intended for the pieces of furniture that can be received therein, such that a disinfectant introduced into the device remains within the cover. The disinfectant may be a gas, a mist or a smoke, wherein a mixture of a gas and a liquid are referred to as a mist, and a mixture of a solid phase and a gaseous phase being referred to as a smoke. The disinfectant may for example be a mist made up of air/hydrogen peroxide, air/peracetic acid, or a mixture thereof. Advantageously, the liquid used for generating the mist comprises silver ions. The disinfectant may also be a gas such as ozone, formaldehyde or sulfuryl fluoride. It is also possibly and optionally provided, according to the invention, that the disinfectant is a smoke made up of air/pyrethrum. The smoke may also be a flue gas that develops from burning organic material such as wood.
In order to make it possible to comply with the strict hygiene regulations in hospitals, it is advantageous to disinfect the hospital bed using a suitable disinfectant in addition to sanitising and wiping surfaces of the hospital bed. In the field of furniture restoration, for pieces of furniture that are made of wood and infected with wood pests, for example, the wood pests remaining in the wood of the piece of furniture can be combatted by the disinfectant.
In larger hospitals or in restoration companies, disinfection mostly takes place in a central disinfection facility, such that the disinfection of individual hospital beds or pieces of furniture is associated with high logistical complexity. The hospital beds have to be brought to the central disinfection facility from the relevant ward in which the hospital beds are used, and have to be stored and disinfected in said facility for a relatively long period of time The disinfection facility has to be kept available and has icy be maintained. Transporting the hospital beds is associated with considerable staffing resources, especially since, when beds are change frequently, a hospital bed has to be disinfected again after a short period of time.
By contrast, the device designed to have the cover allows the hospital bed to be disinfected in a decentralised manner, close to the location in which the hospital bed is actually used, i.e. in an unused room or in a corridor region on the ward in question, for example.
The cover seals the usable volume covered by the cover from the surroundings, to which volume the disinfectant can be applied during the disinfection. As a result, environmentally damaging disinfectants may potentially also be used without separate protective measures being required for the surroundings. Furthermore, for a usable volume adapted to the size of the pieces of furniture or hospital beds to be received, the quantity of disinfectant required for the disinfection can be reduced, in particular in comparison with the otherwise standard rooms that are usually used as a central disinfection facility in hospitals,
Sealing of the cover may be adapted to the disinfectant that is provided in each case. For example, sealing, of the cover that is sufficient in practice for a mist-like, non-environmentally hazardous disinfectant can be ensured by a cover having a simpler design, compared with the sealing for a gaseous, potentially toxic disinfectant.
The cover may be made of a flexible material, for example a plastics film, wherein the cover surrounds the support rack on all sides and being fixed to the floor in an adhesive and sufficiently sealing manner for the duration of a disinfection process. It is also possibly and optionally provided, according to the invention, that the cover comprises dimensionally stable cover side-wall elements and a dimensionally stable cover roof element, which are interconnected ire a disinfectant-tight manner and surround the support rack and the pieces of furniture arranged therein. In order to bring about sealing against the floor, movable sealing elements resting on the floor may be provided by the cover side-wall elements for the decontamination, wherein the respective sealing elements are also formed and arranged in sealing manner on contact surfaces with adjacently arranged sealing elements of adjoining cover side-wall elements.
It is also conceivable that, in an alternatively possible configuration of the cover, the cover side-wall elements together with the cover roof element form a dimensionally stable cover housing which is open towards the floor and can be moved towards the floor for the duration of the disinfection in order to be positioned on the floor in a sealing manner and to surround the usable space in the cover in a sealing manner together with the floor.
With regard to a cover of the usable space that is as sealed and reliable as possible, it is likewise possible and conceivable for the cover to further comprise a cover floor element, which delimits and seals the cover housing towards the floor. The cover floor element may be arranged at a short distance above the floor and is merely intended to make it possible to move the device. The piece of furniture or hospital bed to be disinfected then only has to be rolled or pushed onto the cover floor element arranged directly above the floor, wherein it is possible for extendable ramps or rails to optionally be used as an aid.
In order to introduce the disinfectant into the cover, it is advantageously provided that the device comprises a disinfectant supply apparatus, wherein the disinfectant supply apparatus is able to introduce the disinfectant into the cover of the device such that the pieces of furniture arranged in the device can be disinfected by the disinfectant. The disinfectant supply apparatus may for example be a misting system, a gas-introduction system or a flue-gas-generating system. The disinfectant supply apparatus may be arranged within the cover or outside the cover and may preferably be fastened to the support rack.
According to an advantageous implementation of the concept of the invention, it is provided that the device comprises a connection apparatus, wherein it is possible to introduce the disinfectant into the device from outside the cover through the connection apparatus. In such a configuration of the device, the disinfectant provided by the disinfectant supply apparatus arranged outside the cover is introduced into the cover through the connection apparatus. It is also possibly and optionally provided, according to the invention, that a disinfectant supply apparatus that is separate from the device is connected to the device by means of the connection apparatus.
As a result, in an advantageous manner, a transportable disinfectant supply apparatus can be connected to the connection apparatus as required and can be used to disinfect pieces of furniture arranged in the cover, for example.
The connection apparatus may also comprise a connection element accessible from outside the cover, to which element a disinfectant tube of the disinfectant supply apparatus can be connected so as to be gas-tight, in a force-locked and optionally form-fitting manner.
In another advantageous implementation of the concept of the invention, it is provided that the device comprises a monitoring apparatus, wherein it is possible to record furniture information regarding the pieces of furniture arranged in the device by means of the monitoring apparatus. The furniture information may for example include a furniture identification number assigned to the relevant piece of furniture or a period of time since the last disinfection. From the period of time since the last disinfection, the point in time at which the next disinfection of the piece of furniture is due is fully automatically indicated to the user at predetermined disinfection intervals.
The furniture information, such as the furniture identification number, may for example be manually input by the user using an input element, such as a touch-sensitive dot-matrix display element. It is also possibly and optionally provided, according to the invention, that the furniture information can be electro-optically detected by the user. For example, a barcode attached to the piece of furniture can be detected by a barcode reader. Alternatively, the furniture information may also be detected in an automated, contactless manner by reading out a transponder of the relevant piece of furniture. The furniture information may be displayed to the user on a display apparatus, such as the touch-sensitive dot-matrix display element.
In an advantageous manner, the monitoring apparatus comprises a communication apparatus, which allows for preferably wireless communication with external communication devices in order to make it possible to exchange information detected by the monitoring apparatus, including the furniture information, with the external communication devices. The monitoring apparatus may optionally be connected to a central logistics facility in a data-transmitting manner by means of the communication element, such that the monitoring apparatus can transfer the furniture information as well as other relevant information to the logistics facility when required or at predetermined intervals. In this way, the furniture identification number or the period of time since the last decontamination for the pieces of furniture received in the device can be accessed at the central logistics facility, for example. If the device is intended for use at frequently changing locations, the device may also comprise a GPS module or another position sensor or position-information transmitter and may transmit the current location of the device.
The data-transmitting communication with external communication devices or with the central logistics facility may for example be established over a wireless local area network, by data transmission over short distances between devices by wireless technology, or over a mobile-communications connection.
