A SUSPENSION DEVICE FOR SUSPENDING THE CONTAINER OF A CENTRAL VACUUM CLEANER FROM A WALL

DISPOSITIF DE SUSPENSION POUR SUSPENDRE LE CONTENANT D'UN ASPIRATEUR CENTRAL A UNE PAROI

English Abstract

To suspend a container (1, 5) of a central vacuum cleaner form a wall, use is
made of a suspension device according to the invention which consists of a
first bracket part (3) for attachment to a wall and a second bracket part (2)
which is capable of engaging the first bracket part and is secured to the
container. The first bracket part (3) is configured as a wedge-shaped housing
having a rear wall (12) and a front opening (11) which are defined by
longitudinal walls (8) and a transverse wall (7) connected at the narrow end
of the housing with the longitudinal walls. In extension of the longitudinal
walls, further, longitudinal walls (9) are provided perpendicularly to the
longitudinal walls, said further longitudinal walls having their free edges
provided with holding flanges (10) disposed perpendicularly to the rear wall
(13). The second bracket part is configured in a similar manner, but without
holding flanges. The suspension device according to the invention is unique in
that the second bracket part may engage the first bracket part from both ends
of the first bracket part, which is an advantage in connection with a central
vacuum cleaner which is made with both small and large containers, as a small
container has its motor placed on top of the container, while a large
container has the motor placed below the container. Thus, it is possible to
use the first bracket for both large and small containers, said first bracket
being secured to the wall in one or the other direction which is determined by
whether a large of a small container is used.

French Abstract

L'invention porte sur un dispositif de suspension permettant de suspendre un contenant (1, 5) d'un aspirateur central à une paroi. Ce dispositif consiste en une première partie de support (3) à attacher à une paroi, et une seconde partie de support (2) capable de venir en prise avec le premier support et fixée au contenant. La première partie de support (3) est configurée en tant que logement en forme de coin présentant une paroi arrière (12) et une ouverture avant (11) qui sont définies par des parois longitudinales (8) et une paroi transversale (7) reliée au niveau de l'extrémité étroite du logement aux parois longitudinales. Dans le prolongement des parois longitudinales, d'autres parois longitudinales (9) sont disposées de manière perpendiculaire aux parois longitudinales, ces autres parois longitudinales présentant des rebords libres dotées de brides de retenue (10) disposées dans le sens perpendiculaire à la paroi arrière (13). Le second support est configuré de manière identique mais ne comprend pas de brides de retenue. Ce dispositif de suspension est unique du fait que la seconde partie de support peut venir en prise avec la première partie de support depuis les deux extrémités de la première partie de support, ce qui représente un avantage pour un aspirateur central constitué de contenants petits et grands, le petit contenant étant équipé d'un moteur placé sur le contenant et le grand contenant étant équipé d'un moteur placé sous le contenant. Par conséquent, il est possible d'utiliser le premier support pour des contenants grands et petits, le premier support étant fixé à la paroi dans un sens ou dans un autre déterminé par la grandeur ou la petitesse du contenant utilisé.

Description

1
The invention relates to a suspension arrangement for suspending a
container of a central vacuum cleaner from a wall, said suspension
arrangement being formed by a first bracket part for attachment in a wall,
said first bracket part being adapted to engage a second bracket part on
the container, said first bracket part having a rear wall with two
longitudinal
walls from the rear wall, said second bracket part having two longitudinal
walls whose free edges are connected with a transverse wail which is
disposed perpendicularly to the longitudinal walls.
Central vacuum cleaners are usually madamn two versions, where the first
version has a small container, said container facing upwards with its open-
ing, while the second version has a large container, said container facing
downwards with its opening. In both cases, the vacuum cleaner motor is
secured to the edge which is disposed at the opening of the container.
Both types of holders have a suspension arrangement comprising a first
bracket of the same type which is adapted to engage a second bracket
secured to a wall.
Since the opening of the small container is to face oppositely to the opening
of the large container, it is clear that the first bracket on the small
container
will face opposite the second bracket on the large container when the con-
tainers are suspended from a wall.
A suspension arrangement of the type defined above is known from US
Patent No. 6 557 206. This known suspension arrangement has a
bracket which is useful only with the upward orientation of the container,
and thus not in connection with suspension arrangements where the
same bracket is used for containers which face either upwards or
downwards.

Accordingly, an object of the invention is to provide a suspension
arrangement for a container of a central vacuum cleaner, constructed
such that the same brackets may be used, no matter whether a large or a
small container is used for the central vacuum cleaner.
According to the invention, in a suspension arrangement of the type
defined above, the first bracket part is configured as a wedge-shaped
housing having a front opening, said front opening being defined by a
frame which is formed by the two longitudinal walls from the rear side,
which are terminated at their free edges by adjoining, longitudinal walls
disposed perpendicularly to the longitudinal walls, and that the second
bracket part is configured as a wedge-shaped housing having a rear side
and a front opening, said front opening being defined by a frame which is
formed by the two longitudinal walls from the rear side, whose free edges
are terminated by longitudinal walls which are disposed perpendicularly to
the longitudinal walls, said first bracket being adapted to be pushed down
into the hollow in the second bracket, or said first bracket being adapted
to be pushed externally onto the second bracket.
Hereby, the same bracket parts may be used on both types of containers,
as the second bracket is just mounted on the wall in one or the other
direction in dependence on whether a large or a small container is used.
In one embodiment, a transverse wall is connected with the upper ends of
the longitudinal walls, and the free end of the transverse wall in the first
bracket part is terminated by an edge, whereby a good engagement is
achieved between the first and second brackets.
An expedient geometry of the bracket parts is that the first and second
bracket parts are trapezoidal.

The rear wall of the first bracket may be provided with reinforcing ribs
which define an engagement face longitudinally of the rear side extending
from the edges of the rear side and centrally inwards toward the centre,
so that the engagement face gets a surface which has a geometry
corresponding to the width of the longitudinal walls and the width of the
transverse wall. A strong bracket is then achieved with which the second
bracket can get a good grip.
The invention will now be explained more fully with reference to the draw-
ing, in which

fig. 7 shows the bracket part of fig. 6, seen from below.
In fig. 1 and fig. 2, the numeral 1 designates a container of the so-called
small type which is used in connection with a central vacuum cleaner,
which is a vacuum cleaner type which is coupled via a pipe connection
network to a stub 4 on the container, and where several outlets are con-
nected to the pipe connection network, in e.g. various rooms, to which vac-
uum cleaner hoses may be connected, it being hereby possible to vacuum-
clean several rooms with the same vacuum cleaner, without it being neces-
sary to move the vacuum cleaner to the individual rooms.
The container in fig. 1 and fig. 2 has the actual vacuum cleaner motor posi-
tioned on top of the opening of the container, which, however, is not shown
in the figures. As will be seen, a first bracket 2 is provided on the actual
container, which may be connected with a second bracket 3 which may be
secured to a wall.
In fig. 1, the first and second brackets are shown just before they are inter-
connected, while they are shown in a connected state in fig. 2.
Fig. 3 shows a container 5, which is of the so-called large type, for a
central
vacuum cleaner. This container, too, has a stub 6 for connection to a pipe
connection network (not shown). In relation to the small container 1, the
large container 5 has its opening facing downwards so that a vacuum
cleaner motor (not shown) may be connected with the downwardly facing
opening of the container.
This container is moreover provided with the same first bracket 2 as the
container shown in fig. 1 and fig. 2, which may be connected with a second
bracket 3 which is of the same type as shown in fig. 1 and fig. 2.

The difference is that the bracket 2 in fig. 3 is turned 1800 relative to the
bracket 3 in fig. 1 and fig. 2.
With reference now to figures 4 ¨ 7 it will be explained more fully how the
5 first bracket 2 and the second bracket 3 are constructed.
As-will be seen in fig. 4 and fig. 5, the first bracket 2 consists of a wedge-
shaped housing having a rear wall 13 and a front opening 11, said front
opening being defined by a frame which is formed by at feast two longitudi-
nal, narrow walls 8 from the rear wall, which are formed in their free edges
with even narrower, longitudinal walls 9 disposed perpendicularly to the
longitudinal walls 8, said even smaller longitudinal wails 9 being formed
with narrow edges 10 at their free edges.
A narrow, transverse wall 14 is provided between the narrow walls 9 at the
narrow end of the bracket and is connected with the longitudinal, narrow
walls 8. The free end of this narrow, longitudinal wall is also formed with an
even narrower wall 15 which is disposed perpendicularly to the transverse
wall 14, the free edge of said narrower wall being formed with an edge 16.
Reinforcing ribs 12 as well as screw holes 17 are provided on the rear side
of the first bracket.
The reinforcing ribs are defined relative to the outer edges of the rear side
in such a manner as to provide an engagement face 18 on the rear side.
As shown in fig. 6 and fig. 7, the second bracket 2 is here constructed in
the same manner as the bracket 3 in fig. 1 and fig. 2, but without reinforcing
ribs and screw holes.
Thus, the bracket consists of a wedge-shaped housing having a front

opening 19, a rear wall 24, a frame defined by longitudinal, narrow walls
20, a transverse, narrow wall 21 as well as even narrower walls 22 and an
even narrower transverse wall 23, said even narrower walls being disposed
perpendicularly relative to the longitudinal walls and the transverse wall.
it will then be explained how the first and second brackets are intercon-
nected in the situations where the second bracket is arranged on the small
container shown in fig. 1 and fig. 2, and alternatively is arranged on the
large container in fig. 3.
When the first bracket is used in connection with the small container, it is
screwed into a wall with the broad part of the wedge-shaped part upwards.
Then, the first bracket 2 is pushed down into the hollow in the second
bracket 3, whereby the longitudinal walls 9 and the transverse wall 15 grip
the rear side of the first bracket.
When the first bracket 2 is used in connection with the large container, it is
screwed into a wall with the broad part of the wedge-shaped part down-
wards. Then, the first bracket 2 is pushed externally on the second bracket
3, whereby the narrow walls 22, 23 hold the bracket against the engage-
ment face 18.
