Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to a vacuum cleaner according to the preamble of claim 1.

In known vacuum cleaners of this type, the case part is connected in a blowing manner to the cleaning tool of the vacuum cleaner via a suction pipe. After the dust-laden suction air stream coming from the cleaning tool has passed through the dust filter and the dust collection container, the suction air stream generated by the suction blower flows into the suction blower 1. Ru.

If the dust collection container is, for example, a disposable bag, the dust filter and dust collection container should be emptied at regular intervals.
This has to be replaced.

Since large quantities of dust require frequent emptying or replacement of dust filters and dust containers, the cover must also be able to be opened and closed again easily, quickly and without special preparations.

For this purpose, the cover is pivotally and irremovably fixed to the case part n-1, so that the cover remains on the case part in the open position, and therefore it is necessary to remove the cover from the case part and place it in the storage area. There is no. However, the cover is relatively large and heavy, so the cover or its pivot part is the cover? by pushing or when installing the dust container.
It may also be damaged or destroyed when the cover is opened carelessly. In this case, the cover or case part usually has to be replaced, which is a considerable effort, time consuming and costly.

The object of the invention is to design a vacuum cleaner of this type in such a way that the cover and the case part are not damaged or destroyed if the cover is pushed or opened inadvertently. The idea is to form it in such a way that it never happens.

The above-mentioned problem is solved in the case of a vacuum cleaner of this type by the characterizing part of claim 1.

With the arrangement according to the invention, if an excessive force is applied to the open cover, the cover can be moved from its open position into its released position, in which case the cover can avoid forces acting on it. In this case the cover can be moved beyond the open position without any load until it contacts the case part. Pivoting the cover outwards does not damage the cover or the case parts. Since the cover is retained by the case part even in the open position, a movement in the opposite direction can easily and quickly return the cover to the closed position.

Other features of the invention will become apparent from the other claims, the description and the drawings.

The invention will now be explained in more detail with reference to some embodiments and with reference to the accompanying drawings.

FIG. 1 shows a part of a vacuum cleaner case l. A motor case is housed within the case l. The length of the motor is determined by the intake air flow coming from the cleaning tool of the vacuum cleaner (not shown), and
Via a suction pipe, which is not shown neatly, it is fed to a dust filter and a dust collection container, which is formed as a bag 3. Bag 3 is cover 5
It is located in the receiving space 4 of the case part l which can be closed by. The bag 3 has said receiving space 4 in order to be emptied or replaced if it is configured as a disposable bag.
It can be easily taken out from the storage space 4 and put back into this receiving space 4 easily and quickly.

The bag 3 is connected to a suction air feed pipe, which is not shown clearly. The suction airflow generated by the motor blower 2 is transferred to the bag 3
flows through. In this case, accepted 'i1. The collected dust must be disposed of at regular intervals.

The cover 5, which has a very flat design, is pivotally and irremovably connected to the case part l via a pivot arm 6.1.
I'm here. It is a long, plate-shaped lever with six rotating arms and two arms. One lever arm 7 is bent in an arc in the longitudinal direction and has a narrow holding portion 18 extending radially with respect to the lever arm 7 and extending approximately half its length.
Turn around the rotation axis line 8! ll is pivotably fixed to the case part l n2. A cover 5 is pivotably supported on another lever arm 12, which is formed immediately and has approximately the same length as this lever arm 7.

The pivot axis 9 of the cover 5 closely adjoins the concavely bent edge portion 7b of the lever arm 7. Lever arm 7
The free end 7a is formed by a thin elastic narrow portion 1o. This elastic narrow part oha is the arm part to' between the holding narrow part I8 and the lever arm 12 (Fig. 2).
and considerably thinner than lever arm I2. Swivel arm 6
The ends 7a and 12a of the retaining device II, 1
It has 6, 13 and 14 locking members II or 13. By means of these retaining devices 11, 16 and 13, 14, the cover 5 is shown in FIG. 2 and is locked relative to the case part 1 in its open position.

In this open position, the locking member II of the lever arm 7 is formed in a cam shape and the locking member II of the case wall 17 is formed in a cam shape.
On the other hand, a scrap-shaped locking member 3 of the lever arm I2 is joined to a hanger-shaped opposing locking member 14 of the cover 5. The pivoting arm 6 is at the same time supported by the projection 20 on the inner surface 15 of the cover 5, so that the cover 5 is supported by the retaining device 13 when opened.
, 14, so that the locking device can be released without hindrance when in the closed position and during the open position. Ru.

In order to open the cover 5, move the cover 5 in the direction of arrow P in FIG.
When the lever arm 7 is pivoted, the pivoting arm 6, which is firmly connected to the cover 5 through the retaining device 13,'14i, also locks the locking member 11 at the end 7a of the lever arm 7 against the case wall.
Locked to the opposing locking member 16 of 7 n.

swivels around the pivot axis 8 in the case part l until it reaches its position. In this case, the holding narrow part J8 comes into contact with the stop 19 of the case part l, so that the pivot arm 6 cannot pivot beyond the open position. The cover 5 is then in a position approximately perpendicular to the housing part l and thus in an open position such that the bag 3 can be removed from the receiving space 4 and then placed again into this receiving space 4.

When opening the cover 5, the narrow holding width gA of the lever arm 7
Smooth concave bent edge portion 7C on the side opposite to ts
is used as a guide part, by means of which the pivoting arm 6 slides along the free end 17a (IT diagram) of the housing wall 17. Therefore, when the cover 5 is pivoted, the case part 1
c is accurately corrected, and as a result, the cover 5 can be turned smoothly, and damage to the pivot joints is completely prevented. For example, when the bag 3 is removed from the bag 3 or when the cover 5 is pierced during reinstallation, or due to careless operation when opening the bag 5, the cover 5V may be damaged.
C If excessive force is applied, the cover 5 will pivot beyond the open position into the released position (FIG. 3). The opposing locking element r4Lri is then pushed past the locking element 13, so that the holding element 13.14 is released and the cover 5
can avoid the force acting on the cover in the direction of arrow P.

On the other hand, the locking connection of the holding device lI, 16 remains.

This is because the stop 19 of the case part I prevents the pivot arm 6 from rotating. This avoidance movement of the cover 5 ensures that force effects on the cover 5 and thus on the case parts do not cause damage or destruction to these parts.

The cover 5 can be simply and quickly brought into the closed position (FIG. 1) from the above-mentioned open position by pivoting in the direction opposite to the arrow P. At that time, the holding devices 13, 1 are automatically
The locking connection of 4 occurs again and the retaining devices 11, 1
The lock connection of 6 is released 1. Therefore, the cover
After closing, it can be opened again without requiring any additional measures.

In the embodiment shown in FIGS. 4 to 6, the pivot arm 32 is formed integrally with the cover 31. In the embodiment shown in FIGS. The rotating arm 32 is bent in an arc shape over its entire length,
All parts are formed to have the same width. cover 31
When pivoting, the pivoting arm 32 slides on a bearing part 34 of the case part 30, which is formed in the form of an open circle. In order to fix the cover 31 relative to the case part 30 and to open it smoothly, guide parts 21 , 22 are provided in which the pivoting arm 32 and the bearing part 34 engage elastically in a groove-like manner.
has.

These guide parts 21, 22U are formed by corresponding profile parts. As shown in particular in FIG.
It has a U-shaped cross section with 3,24. This fl
, [On the other hand, the guide part 22 of the bearing part 34 is formed by a narrow part that is U-shaped in cross section. This narrow portion forms a corresponding guide portion 21 of the pivoting arm 32.
It protrudes into the recess in a shape-closed manner. For reinforcement purposes, the outer areas of the bearing part 34, the support surfaces 26, 27 for the legs 23, z4 of the pivot arm 32 are made thicker than in other areas.

The holding devices 33, 35 consist of a locking member 33 of the pivot arm 32, which is formed as an elastic locking cam, and a locking opening in the bearing part 34 forming a counter-locking member 35 (see FIG. 4). (FIG. 6) The zero-opening member 33 is closely adjacent to the concavely bent edge portion 28 of the swing arm 32 and the opening 21Vc. The locking member 33 is spaced from the free end 29 of the pivot arm 32 at a distance corresponding to approximately 1/4 of the length of the pivot arm 32. This spacing ensures that the pivoting arm 32 and the bearing part 34 are not disengaged in the released position of the cover 31, so that the cover 31
The design is such that it can be easily and quickly moved from this open position back to the closed position.

The opposing locking member 35 is located between the radially outer shielding 1, the edge portion 38 and the narrow guide width portion 22 in the opening direction (arrow P
) at the forward end 39.

The cover 31 is locked in its open position by the retaining devices 33, 35, and the cover 31U can also be moved beyond the open position in the direction of the arrow P via the retaining devices 33, 35 to avoid damage. As a result, excessive force can be avoided.Furthermore, as can be seen from FIG. 35 or into the opposing locking member 35 so that the cover can be moved into its released position or past the open position when closed. The force required for this is the locking member 33
Alternatively, it can be varied by selecting the acute angle of the opposing locking member 35 to be smaller or larger.

The embodiment of FIGS. 7 and 8 differs from the above-described embodiment simply in that the holding device 45 is formed as a leg springer. Similarly to the cover 41Fl, it is shaped like an arcuate disc. It is integrally coupled with the pivoting arm 42 of j. Swivel arm 42
are pivotably guided by 1° above the circular bearing part of the case part 40 by means of guide parts 35, 37 (FIG. 8) which engage one another elastically in the form of grooves. Therefore, force,

The ends of the middle leg spring 45 are fixed to the retaining projections 48 and 49 of the case part 3 and the cover 31. The cover 41 is elastically held in its open position by a spring 45. leg spring 45
The pre-tension is selected such that the cover part 41 automatically pivots into its open position. For example, the stop at which the legs 46, 47 of the leg spring 45 join limits the maximum permissible opening angle α of the legs 46, 47 (FIG. 1O). The stop limiting the maximum permissible opening angle α can be formed, for example, as a capsule 50 (FIGS. 9 and 10) that engages coaxially with the winding of the leg spring 45. Parts of the capsule wall are spaced apart, resulting in two stop ridges 5 and 52, to each of which the legs 46 and 47 of the leg spring 45 are joined with a maximum permissible opening angle α. Other possibilities for limiting the maximum permissible opening angle α (Fig. 11,
In FIG. 12), the stop is formed as a plate 53, and the mounting plate 53 is provided with openings 54, 54' in which the legs 46 of the leg spring 45 are inserted.
47 stands out. The maximum permissible opening angle α of the legs 46 and 47 is determined by the fact that their legs are joined to the walls of the openings 54, 5, which are located at a maximum distance from each other. Another possibility is to pre-tension the leg spring 45 in both legs 4 in the relaxed state of the leg spring 45.
6 and 47 are selected to be smaller than the maximum permissible opening angle.

In order to further open the cover part 41,
1 I need to move it further by hand. In order to avoid deformation of the leg spring 45, it is advisable to limit the maximum permissible opening angle α and, for example, the aforementioned stop element 50 or 53 by 7. The maximum opening angle α is smaller than 180°.
