Abstract

A device for retracting and storing a hose (1) into a pipe system within a wall, wherein the hose (1) forms, in its active position, an extension of a suction pipe (2), and wherein the hose (1) is placed, in its inactive position, in the suction pipe (2), the hose being arranged to be pulled/pushed into the suction pipe (2) for example by means of a thread system (3), a driving belt (8) and an electric motor (7), whereby the external profile of the hose (1) may work as a thread.

Description

RETRACTION AND STORAGE OF A HOSE IN A PIPE SYSTEM
This invention relates to a device for storing a hose, more particularly a device, in which the hose is displaced into a pipe system.
When a central vacuum cleaner system according to known technique is used, a 9 - 10 m long hose is normally connected to a pipe system inside the walls. Such a long hose is awkward to move about and must be coiled after use and taken to a storage place, where it is stored till the next time it is going to be used.
The invention has as its object to remedy-the drawbacks of known technique.
The object is achieved according to the invention through the features specified in the description below and in the following Claims.
When the hose is to be stored, it is displaced into the pipe to which it is connected in its operating position. During the retraction into the pipe, the hose is compressed axially and occupies a substantially shorter length than in its active position.
For example, an electric motor may be used to drive a screw mechanism feeding hose into the pipe within the wall. In such an embodiment the hose could be disposed of just by pressing a button. The hose will be pulled into the wall and into the pipe system which is already in use for the central vacuum cleaner system. This will save time, effort and, not least, storage space.
The invention comprises a hose, wherein a spiral lies on the outside of the hose, and in which the inner hose is attached to the inside of the spiral. The spiral works as threads in the retraction which is effected by means of thread system. The thread system is rotated by an electric motor. The hose is driven inwards by the thread system and compressed to a certain length by means of a hose stop.
The invention is suitable for a system in which a hose is attached to the end of a pipe, the hose and the pipe performing a joint function. The function may be to suck air or liquid in or out. This system is particularly suitable in connection with a central vacuum cleaner.
The hose may be stored in the pipe system regardless of where in the building the pipe system is placed. It is advantageous that the pipe system has a certain straight length within the wall, but it does not matter whether this length is directed sideways, upwards or downwards. It is also conceivable for this system to be used in systems other than a central vacuum cleaner, e.g. in a large industrial vacuum cleaner. The hose may be retracted into the machine by means of the same thread system and be stored in the machine within a pipe system. The driving power for the thread system may be for example a steel wind-up spring. As the hose is pulled out, the wind-up spring will be tightened, and the energy created thereby, is used when the hose is pulled back in.
The system may be used for industrial purposes, in which the hose may be used to suck in water, oil and similar.
It is of advantage to use a spiral hose with a spiral outermost and a soft and strong hose secured to the inside of the spiral. This configuration is practical because of the fact that the spiral will then work as threads during retraction. The hose may also be configured in other ways which will imply that it will have the same function as a spiral hose. An example is that it is formed according to the accordion principle. Each link is soft and yielding, so that the hose may be compressed. Between each link there may be a hard material, which provides a certain rigidity in the hose. A version of this hose is disclosed in the patent EP 0 917 851 Al.
Instead of a thread system a cogwheel system may be used, in which the teeth of the cogwheel engage a hose which is of such configuration that its teeth mate with the teeth of the cogwheel. This will carry the hose upwards.
In the following is described a non-limiting example of a preferred embodiment, which is visualized in the accompanying drawings, in which:
Fig. 1 shows an overview of a pipe system with stored hoses across 3 floors;
Fig. 2 shows part of a pipe system with drawings of a stored hose and a hose in use, respectively;
Fig. 3 shows schematically a thread system driven by an electric motor;
Fig. 4 shows a hose stop;
Fig. 5 shows a hose with an end piece;
Fig. 6 shows a cross-section of the hose;
Fig. 7 shows a cross-section of a spiral; and
Fig. 8 shows a thread portion.
In the drawings the reference numeral 1 identifies a hose which is arranged to be stored within a pipe 2.
Fig. 1 shows an overview of how a central vacuum cleaner system with storage of the hose 1 may be configured within a building of several floors. On the ground floor and second floor, the hoses 1 are stored within the pipe 2, whereas the hose 1 on the first floor is in use. The hose 1 which is being used, is connected to a suction pipe 19 and a vacuum cleaner head 20. When the vacuum cleaner on the first floor is in use, the inlets in the walls on the ground floor and second floor are covered to prevent false air from entering the system. The reference numeral 12 identifies a vacuum cleaner motor.
Fig. 2 shows the system both with the hose 1 in a stored inactive position and when the hose 1 is in its active position outside the pipe 2. The reference numeral 1 identifies the hose both stored and in use. The hose 1 is pulled in through the pipe 2 by means of a thread system 3. A spiral 4 of the hose 1 works as threads on retraction of the hose 1. At a specific distance from the thread system 3 a hose stop 6 is attached, where the displacement of the hose 1 into the pipe is stopped, so that on further insertion into the pipe, the hose will be compressed.
Fig. 3 shows that the thread system 3 is driven by an electric motor 7 in that a driving belt 8 is attached to the thread system 3. The electric motor 7 is connected to an electrical switch not shown. Servicing of the system is carried out through a service gate 9.
Fig. 4 shows the hose stop 6 which is formed by a ring of, e.g., rigid plastic of an inner diameter large enough not to prevent air from passing.
The hose 1 shown in Figs. 5 and 6 is formed with the spiral 4 furthest out on the hose 1 and an inner hose 5 of non-rigid plastic, e.g., attached to the inside of the spiral 4. At the end of the hose 1 is an end attachment 14 which may be connected to a suction pipe 19. At the opposite end of the hose 1 is attached an end portion 21 which is to work as an electrical contact between the thread system 3 and the hose 1. The end portion 21 may be formed by a rigid ring. Fig. 7 shows an embodiment of the cross-section of the spiral 4. The spiral 4 itself lies as an arc round an electrical wire 13, the inner hose 5 being secured between the two. The electrical wire 13 is the connection between the vacuum cleaner and an on/off switch at the end of the hose 1.
Fig. 8 shows the thread system 3, the thread system 3 being formed cylindrical with internal threads 16. The part of the system 3 facing the end portion of the hose may have an electrical contact, which mediates electrical contact between a vacuum cleaner motor 12 and an electrical on/off switch, not shown, when connected to the end portion 21 of the hose.
