Abstract

The invention relates to a vacuum cleaner comprising a housing (1) and a carrying arched element (7) mounted in a manner that, by means of at least one pivot bearing (8), which has a first pivot bearing part (9) and a second pivot bearing part (10) that can rotate relative to the first pivot bearing part (9) about a common rotation axis, enables it to pivot relative to the housing (1) between two end positions of an operational pivot angle. The aim of the invention is to create a vacuum cleaner whereby a carrying arched element (7) that can pivot relative to the housing (1) between two end positions of an operational pivot angle is securely mounted in an simple manner. To this end, the pivot bearing (8) is designed for joining or separating the first pivot bearing part (9) to or from the second pivot bearing part (10) in a mounting angular position located outside of the operational pivot angle. This enables the pivot bearing parts (9, 10) of the pivot bearing (8) to be mounted and detached solely in a mounting angular position. The pivot bearing parts (9, 10) cannot be detached when the carrying arched element (7) is located in an operational pivot angle. This makes it possible to eliminate separate parts that would otherwise be necessary for preventing an unwanted detaching of the carrying arched element (7) from the vacuum cleaner.

Description

The invention relates to a vacuum cleaner according to the preamble of claim 1.

Out DE-AS 12 89 628 a generic vacuum cleaner is known in which a support bracket is pivotally mounted in a concentric with its axis of rotation groove of a disc. A bent around a pipe end of the carrying handle is provided with a stop. The groove continues locally to the outer edge of the disc, so that two stops are formed, between which the carrying handle can pivot freely with respect to the disc. By means of this solution, the carrying handle is pivotable relative to the housing between two end positions of an operating pivoting angle. The disadvantage, however, is that the local structure is very complicated and has a high number of individual parts. A vacuum cleaner according to the preamble of claim 1 is made EP0935944 A known.

The object of the invention is to provide a vacuum cleaner in which a pivotable between two end positions of an operating pivot angle with respect to the housing carrying handle is stored safely in a simple manner. In particular, it is an object of the invention to simplify the storage of the carrying handle to the effect that the vacuum cleaner manufactured inexpensively and the carrying handle can be mounted easily and with little expenditure of time in a secure manner. A safe storage of the carrying handle should be achieved in particular by simple means.

According to the invention, this object is achieved in that the pivot bearing is designed for joining or separating the first pivot bearing part of the second pivot bearing part in a lying outside the operating pivot angle mounting angular position.

Characterized in that the pivot bearing parts of the pivot bearing can be mounted or disassembled exclusively in a mounting angular position, which is outside the operating pivot angle, it is ensured that the pivot bearing parts, when the carrying handle is in an angular position, within the operating pivot angle is not disassemblable. This has the consequence that can be dispensed with separate components that would otherwise be necessary to prevent unintentional dismantling of To prevent the carrying handle from the vacuum cleaner. An example, additional axial locking pin for axially fixing a journal in a bearing seat of the pivot bearing can be omitted. This leads to lower manufacturing costs due to the reduced variety of parts and the elimination of an additional assembly step. According to the invention, the first and the second pivot bearing part is designed and matched to one another such that an axial and / or radial securing mechanism is active on the pivot bearing only in the operating angular positions and is not active in the mounting angle positions. In a mounting angle positions of the axial and / or radial locking mechanism does not work and the carrying handle can be separated from the vacuum cleaner or used in this. After the carrying handle is pivoted to an operative angular position, the axial and / or radial securing mechanism is effective, the carrying handle is locked to the vacuum cleaner, and therefore the carrying handle can not be separated from or inserted into the vacuum cleaner in the operating angular positions. For a reliable axial and / or radial securing is achieved without additional components to be mounted.

Preferably, the first pivot bearing part has a bearing journal and the second pivot bearing part has a bearing seat with a cutout, by means of which the bearing journal can be inserted into the bearing seat.

The cutout preferably extends in the radial direction, so that, for example, an arc-shaped carrying handle with two oppositely directed bearing journals can be introduced radially into the bearing seats. This is particularly useful if the carrying handle has a high rigidity, so that the bearing pins directed against each other on the carrying handle can not be bent away from each other by bending the carrying handle in order to use it axially in the bearing seats can. However, should the support bracket have sufficient flexibility, it may be useful to provide an axial recess instead of a radially extending cutout over which the bearing pins are axially inserted into the bearing seats.

The journal may have a radially outwardly extending projection which is aligned with the recess in the mounting angular position.

As a securing mechanism can serve for axial securing of the bearing journal in the bearing seat, the radially outwardly extending projection. The bearing seat then has a cutout that extends beyond the mounting angular position. In the operating angular positions, the bearing seat has no cut-out. The mounting of the carrying handle can be done in the axial direction, wherein the bearing pin in the recess having bearing seat can be inserted, analogous to a key in a keyhole. The beard of the key forms the projection formed on the journal. If the projection is inserted into the cutout on the bearing seat this corresponds to the insertion of the key via the keyhole a lock. If the bearing pin is rotated with the projection in an operating angular position, the bearing pin can not be pulled out axially, as a key turned in the lock can not be pulled out because the beard of the key is present behind the keyhole. The projection is supported for axial securing of the journal in the bearing seat on an end face of the second pivot bearing part.

Advantageously, the cutout of the second pivot bearing part is radially open edge and has a clear width, which is adapted to the diameter of the bearing journal such that the bearing pin is inserted in the mounting angular position in a radial direction in the bearing seat.

In this embodiment, the carrying handle is preferably mounted in the radial direction. Due to the radial open edge cutout on the bearing seat of the bearing pin can be used freely radially into the bearing seat. In this variant, the radial projection does not have to be adapted to the cutout, but only in its size and extension are chosen so that the projection is wider than the inside diameter of the bearing pin receiving bearing seat. The axial securing of the bearing pin is given in any angular position of carrying handle to vacuum cleaner. It only requires a radial securing of the journal in the bearing seat after assembly.

For this purpose, the housing has a first housing part, on which the radially edge-open cutout is formed, and a second housing part, on which a locking portion for closing the cutout is formed.

The design of the locking portion on a housing part has the advantage that can be dispensed with a separate component for radial securing of the journal in the bearing seat. Since no separate component for radial securing is present, this can not be lost as a separate part.

The locking portion may be formed as a wedge-shaped, engaging in the radially open edge cutout of the first housing part housing projection of the second housing part. Thus, the locking portion is integrally formed with the housing part preferably in the plastic injection molding process inexpensively.

If the projection is an axially extending projection arranged at a radial distance from the axis of rotation on the first rotary bearing part, then this projection can engage in a ring channel running coaxially with the axis of rotation on the second rotary bearing part.

This construction variant may alternatively or in addition to the above-described locking portion constitute a radial securing for the bearing pin in the bearing seat. Such a projection can be inserted only in a mounting angular position in the annular channel, or be pulled out of the annular channel. In an operating angular position deviating from the mounting angular position, the projection slides behind an inner circumferential wall and an outer circumferential wall of the annular channel. These peripheral walls define a guideway for the approach such that in the operative angular positions the lug is locked behind the outer peripheral wall. A radial disassembly of the carrying handle is not possible this operating angular positions. Only when the carrying handle is pivoted into a mounting angular position, the approach comes to lie flush with the radially open edge cutout and the bearing pin can be removed radially from the bearing seat.

To achieve a very large operating angular range, it is advantageous if the peripheral walls extend to the radial cutout. Thus, the carrying handle can be assembled or disassembled only in a small angular range, which corresponds to the size of the cutout. A small angular range for the mounting angle position increases the captive, since then in most predominantly angular positions of the support bracket is locked in the bearing seat.

Preferably, at least one stop element arranged on the first pivot bearing part is assigned at least one counter stop element on the second pivot bearing part such that pivoting of the carrying handle from the region of the operating pivot angle into the mounting angular position is prevented.

According to the invention, it is advantageous if the at least one bearing seat is located on a housing part of the vacuum cleaner and the carrying handle has the bearing journal. In this case, the carrying handle can be preassembled on the housing part and the assembly of the housing part and carrying handle can be supplied to the further assembly as a preassembled module further assembly. In order to prevent accidental release of the preassembled connection of the support bracket and housing part, a stop device is provided which prevents a mounted carrying handle, which has already been pivoted into an operating angular position, can pivot back into a mounting angle position. By preventing the pivoting back of carrying handle in a mounting angle position prevents the preassembled unit of carrying handle and housing part can be solved unintentionally.

The first pivot bearing part may have a particular disk-shaped shield element, from the disk center of which the bearing pin extends perpendicularly out of the plane of the shield element, wherein the at least one stop element is arranged on the shield element at a radial distance from the bearing journal.

The formation of the first pivot bearing part as a disc-shaped shield member provides a large-scale support of the first pivot bearing part on the second pivot bearing part, whereby the storage of the carrying handle on the vacuum cleaner takes place in a very stable manner and thus high forces on the handle can be introduced into the vacuum cleaner. This results in a very accurate and stable storage for the carrying handle on the vacuum cleaner. The arrangement of the stop element in the largest possible radial distance from the bearing pin reduces the forces acting on the stop element and on the counter-stop elements when the carrying handle strikes at the end of its pivoting angle range. As a result, damage to the stop elements or counter-stop elements are prevented.

Preferably, the stop element is formed as a the second rotary bearing part facing, wedge-shaped, rising in the circumferential direction locking lug. Due to the wedge-shaped design of the locking lug pivoting of the carrying handle from a mounting angle position in an operating angular position with little effort is possible. A swinging back from an operating angular position in a mounting angular position is possible without damaging the latch at most with considerable effort.

The stopper and the lug can be formed by the same projection. This so combined projection serves on the one hand to prevent the pivot bearing against radial removal of the bearing pin from the bearing seat in an operating angular position and on the other hand to prevent a pivoted in an operating angular position carrying handle can not be pivoted back either in a mounting angular position , Stop element and approach are preferably integrally formed on the first pivot bearing part in the plastic injection molding process.

In a particular embodiment, the second pivot bearing part is formed as a particular pot-shaped drum element, in the center of which the bearing seat is arranged, and on which the at least one counter-stop element is arranged at a radial distance from the bearing seat. The counter-stop element may be arranged in the region of a first and / or a second end of the annular channel bounded by the peripheral walls.

The angular position of the counter stop elements determines the maximum angular range for the operating angular positions. As an alternative to the counter-stop elements formed on the second pivot bearing part, an effective angle stop can also be realized if the carrying handle or the housing part of the vacuum cleaner carrying the carrying handle is shaped such that an angle stop is achieved by the carrying handle on the housing part in its at least one end position pending. An additional counter-stop element is then no longer necessary at this end position.

In a simple embodiment, the counter-stop element is designed as a web extending radially between the inner circumferential wall and the outer circumferential wall. Such a bridge, preferably between the inner and outer Peripheral wall is integrally formed, forms a reliable stop for the stop element and additionally stabilizes the inner and outer peripheral walls.

Preferably, the first pivot bearing part with the carrying handle and the second pivot bearing part is connected to the housing. In this case, the carrying handle on the bearing pin and the bearing seats are mounted on the housing. This variant simplifies the production of housing parts which are produced as plastic injection-molded parts and the manufacture of the carrying handle, which is preferably blow-molded from plastic in the in-water pressure method. In special cases, however, the bearing pin may be formed on the housing parts and the bearing seats on the carrying handle.

In a preferred embodiment, the carrying handle extends arcuately over the contour of the vacuum cleaner, wherein each of the two ends of the arc-shaped carrying handle has a first pivot bearing part which engages in one of two vacuum cleaner on the opposite formed second rotary bearing parts. The carrying handle thereby forms a C-shaped handle on which the vacuum cleaner can be freely swinging suspended similar to a shopping basket.

The invention also relates to a method for mounting a carrying handle on a housing part of a vacuum cleaner and comprises in particular the following method steps:

• Aligning the support bracket relative to the housing part by aligned positioning of a arranged on a first pivot bearing part projection to a radial recess of a second pivot bearing part;
• Inserting the carrying handle into the housing part of the vacuum cleaner by radially inserting at least one bearing journal of the first pivot bearing part into the radial cutout of the second pivot bearing part;
• Pivoting the inserted carrying handle from a mounting angular position into an operating angular position until a stop element arranged on the first rotary bearing part engages behind a counter-stop element arranged on the second rotary bearing part;
• Attaching the assembly formed by carrying handle and housing part to the vacuum cleaner.

The mounting method according to the invention is characterized in particular by the fact that the carrying handle can be preassembled on a housing part of the vacuum cleaner. In this case, no additional assembly operations are necessary during pre-assembly to secure the carrying handle on the housing part. Separate security elements eliminated and can be saved. The preassembled unit of carrying handle and housing part can be fed in a simple way the further assembly of the vacuum cleaner. In particular, the preassembled unit can no longer fall apart due to a locked securing of the carrying handle on the housing part and can therefore be reliably and safely handled during the further assembly.

An embodiment of a vacuum cleaner according to the invention is in FIG. 1 shown. The vacuum cleaner has a multi-part housing 1, are housed in the functional components, not shown, of the vacuum cleaner. A first housing part 2 forms an upper shell, which is mounted on a second housing part 3 forming a lower shell. On an outer bottom side 4 of the housing part 3 rollers 5 are mounted drehund pivotally. The housing part 3 has a rigidly mounted handle 6. In addition to the handle 6, an additional carrying handle 7 is provided. The support bracket 7 is pivotally connected by means of two oppositely disposed pivot bearing 8 with the first housing part 2. The carrying handle 7 extends from an in FIG. 1 left side of the vacuum cleaner to an opposite, in FIG. 1 right side of the vacuum cleaner. The support bracket 7 is bent in a U-shape, extends over the top of the vacuum cleaner at a distance from the first housing part 2 and has at each of its two ends a first pivot bearing part 9, which together with corresponding second pivot bearing parts 10 which on the first housing part 2 are mounted opposite form the pivot bearing 8. In the in FIG. 1 shown position, the carrying handle 7 is in an operating pivoting position in which the vacuum cleaner can be worn by a user. In an in FIG. 1 not shown rest position of the carrying handle 7 rests on the surface of the first housing part 2.

In FIG. 2 is the first housing part 2 and the carrying handle 7 shown in a partial view. It is one of the two pivot 8 from FIG. 1 shown disassembled. In this case, the first pivot bearing part 9 is shown folded away in the plane of the second pivot bearing part 10 to show the inside of the first pivot bearing part 9 and the second pivot bearing part 10. The first pivot bearing part 9 has a disk-shaped shield element 11, which is formed directly on the support bracket 7. Around the outer periphery of the shield member 11 extending around an annular peripheral wall 12 is formed. Starting from this peripheral wall 12, a plurality of reinforcing ribs 14 running inwards towards a disk center 13 extend in a star shape. In the area of the disk center 13, the reinforcing ribs 14 converge on a cylindrical bearing journal 15. The bearing pin 15 is formed perpendicularly from the plane of the shield member 11 extending out to the shield member 11. At an axial distance A from the plane of the shield element 11 is in the region of a free end 16 of the journal 15 a Projection 17 formed. The projection 17 is formed as a dovetail-shaped tongue extending in the radial direction from the bearing pin 15 and parallel to the plane of the shield member 11. Below the projection 17 a space bounded by two stiffening ribs 14 space segment 18 is full material filled. On a in the assembled state of the second pivot bearing part 10 facing surface of the space segment 18, a stop element 19 is integrally formed. The stop element 19 is arranged at a radial distance B from the bearing pin 15 and is wedge-shaped. The wedge-shaped stop element 19 has an in FIG. 2 clockwise flat rising edge 19a and a in FIG. 2 counterclockwise steeply sloping edge 19b. The stop element 19 and the projection 17 are aligned with one another on the first pivot bearing part 9 in such a way that they lie in the area of the same space segment 18 of the disc-shaped shield element 11.

The integrally formed on the first housing part 2 second pivot bearing part 10 is formed as a cup-shaped drum member 20. The drum element 20 has a circular disk-shaped bottom surface 21, which simultaneously forms a side wall 22 of the first housing part 2. Along the edge of the circular disk-shaped bottom surface 21, a cylindrical jacket wall 23 of the drum member 20 extends perpendicular to the side wall 22. Coaxially with the cylindrical jacket wall 23, a bearing seat 24 is arranged in the center of the drum member 20. The bearing seat 24 has an annular wall 25, on which in the assembled state of the rotary bearing 8 of the bearing pin 15 of the first pivot bearing part 9 is rotatably mounted. The annular wall 25 is not closed over the entire circumference, but only over part of the circumference.

The clear width over which the annular wall 25 is provided with a radial cutout 26 and thus open, is slightly wider than the diameter of the bearing journal 15 on the first pivot bearing part 9. The radial cutout 26 extends not only over the annular wall 25, but also over the bottom surface 21 up to the jacket wall 23, in FIG. 2 starting from the center of the second pivot bearing part 10 shown running vertically downwards. In a mounting angular position of the first pivot bearing part 9 and the second pivot bearing part 10 of the projection 17 is aligned with the radial recess 26 so that the first pivot bearing part is selectively inserted in the axial or radial direction in the second pivot bearing part until the bearing pin 15 is inserted into the bearing seat 24 and is held. Will the carrying handle 7 and the first pivot bearing now from the mounting angle position rotated in an operating angular position, the projection 17 slides behind a the interior of the vacuum cleaner facing end face 27 of the side wall 22 and the bottom surface 21. If the projection 17 so no longer aligned with the radial freisparung 26, is an axial separation of the first Rotary bearing part 9 and second pivot bearing part 10 prevented. For radial securing of the bearing pin 15 in the bearing seat 24, a locking portion 28 is integrally formed on the second housing part 3. The locking portion 28 is formed as a housing projection formed on the second housing part, which corresponds in shape and size of the radial recess 26.

Alternatively or in addition to a radial securing of the journal 15 in the bearing seat 24 by means of the integrally formed on the second housing part latch portion 28, a second projection on the first pivot bearing part 9 is provided. This second projection is formed on the segment 18 of the first pivot bearing part 9 as an axially extending projection 29 integrally formed at a radial distance from the axis of rotation. The radial securing is effected by the engagement of the projection 29 in a cutout, which is formed as an annular, open in the axial direction of the annular channel 30 when the carrying handle 7 and the first pivot bearing part 9 is in an operating angular position. The annular channel 30 extends in the manner of a circular ring segment coaxially with the bearing seat 24 and is delimited by an inner circumferential wall 31 and an outer peripheral wall 32. The inner peripheral wall 31 and the outer peripheral wall 31 extend less than the entire circumference of the second pivot bearing part 10, leaving the radial cutout 26 free. The inner peripheral wall 31 and the outer peripheral wall 31 are circumferentially uniformly distributed to stabilize their shape by a plurality of radially aligned ones Ridges 33 supported. The ribs 33 are formed between the peripheral walls 31 and 32 and have a height which is chosen sufficiently small so that the stop member 19 and the projection 29 in the mounted state of the pivot bearing 8 can slide over the ribs 33 away.

However, at least one rib extends over the entire height of the peripheral walls 31 and 32 and thereby forms a counter stop element 34 for the stop element 19. The counter stop element 34 is arranged in the region of one end of the limited by the peripheral walls 31 and 32 annular channel 30. In a mounting angle position ( Fig. 3 ) of first rotary bearing part 9 and second rotary bearing part 10, the stop element 19 is located within the radial recess 26 on a radial circumference of the annular channel 30. By pivoting the carrying handle 7 in an in FIG. 3 counterclockwise running direction, the first pivot bearing part 9 is rotated relative to the fixed second pivot bearing part 10 in an operating angular position. In this case, the stop element 19 moves counterclockwise from below onto the counter-stop element 34. The gently rising flank 19a of the stop element 19 slides over a ramp 35 located upstream of the counter stop element 34 and snaps into the annular channel 30 behind the counter stop element 34. If the carrying handle 7 is pivoted back again from this reached operating angular position in a clockwise direction ( Fig. 4 ), so comes the stop element 19 with its steeply sloping edge 19b on one of the ramp 35 opposite side of the counter-stop member 34 to the plant. Due to the steep slope 19b and the absence of a ramp on this side, the stop member 19 can not slide over the counter-stop member 34 and pivoting of the support bracket 7 from the operating angular position in the mounting angular position ( Fig. 3 ) is reliably prevented. In a direction to the stop direction Fig. 4 opposite direction of rotation, for example, counterclockwise ( Fig. 5 ), a separate second counter-stop element can be dispensed with, if a pivoting of the carrying handle 7 beyond the operating angle out into a mounting angular position is therefore prevented because the carrying handle 7 comes through at the contour of the first housing part 2 to the plant before the mounting angular position is reached. In this case, the first housing part 2 forms the counter-stop element which engages directly on the carrying handle 7. In the in Fig. 5 shown position, the carrying handle is in a normal operating position on the vacuum cleaner.
