STATE OF THE ART

A large number of types of vacuum cleaners with different methods for absorbing solids and liquids are known, which include a large number of separate accessories, e.g. Have exchange attachments, pipes, nozzles. Some of these accessories are arranged on the vacuum cleaner and some are kept separately from the vacuum cleaner. The handling is usually difficult or hindered when operating the vacuum cleaner.

OBJECT OF THE INVENTION

The object of the invention is therefore to provide a vacuum cleaner with a drawer element for storing and providing vacuum cleaner accessories and a method for opening and closing the drawer element, which is a simple, user-friendly and safe opening and closing of the drawer element and a simplified provision of the vacuum cleaner accessories at one enables trouble-free operation of the vacuum cleaner.

TECHNICAL SOLUTION

The object is achieved by a vacuum cleaner according to claim 1 and method for opening and closing according to claims 8 and 9.

The vacuum cleaner according to the invention comprises a vacuum cleaner housing and a drawer mechanism for moving a drawer along a distance A, the drawer mechanism comprising a drawer element, at least one guide device, at least one drive element and a latching element, the guide device being suitable for guiding the movement of the drawer element, the drive element is suitable for movement of the drawer element relative to the vacuum cleaner housing and the locking element is suitable for assuming a state in which movement or locking of the drawer element is made possible.

The vacuum cleaner can comprise any known way of absorbing and binding solids and liquids, e.g. with or without dust bag. The vacuum cleaner can also be a water vacuum cleaner, for example.

The drive element is suitable for generating a constant and uniform movement of the drawer element.

The drawer element preferably has a holding element. The holding element is usually arranged on the underside of the drawer element and is suitable with the locking element to cooperate. For this purpose, both elements have a coordinated geometry. If a movement of the holding element is described in this application, this always includes the movement of the drawer element connected to it.

In an advantageous embodiment, the vacuum cleaner housing has a drawer receptacle, the latching element being pivotably mounted on the drawer receptacle and having a receiving area for the holding element of the drawer element, the receiving area having a movement area, a locking area, a closing stop and an opening stop.

The drawer holder is on the vacuum cleaner or on the vacuum cleaner housing with suitable connecting means, e.g. Screws attached and is usually located under the drawer element or in the area along the route A, which is covered when opening and closing the drawer element. The drawer holder serves as a holder for the guide device, the locking element and the drive element. The drawer receptacle is preferably made as an injection molded part.

The locking element is on the drawer receptacle by suitable connecting means, e.g. a snap mechanism arranged relatively centrally and pivotably below the drawer. The holding element of the drawer element moves the locking element by means of special curve geometry and shapes of the locking element. The latching element thus has a range of motion and deflection bevels or guide surfaces formed by suitable geometries cause the latching element to pivot. The locking element can also be an injection molded part.

The guide device preferably has a telescopic rail arrangement. The guide device is secured with suitable fastening means, e.g. Screws attached to the drawer receptacle and / or to the drawer element. As a rule, the guide device is in pairs, so that two telescopic rails are arranged under the drawer on the left and right, parallel to the section A. The submission of the guide serves to linearly guide the drawer along the route A. The telescopic rail is constructed in several parts and generally comprises a telescopic rail guide and at least one telescopic pull-out. One element is connected to the drawer receptacle and the drawer element. As a result of the multi-part construction, the drawer element can be easily dismantled without loosening the connecting means. Suitable unlocking means on the telescopic pull-outs enable disassembly.

In an advantageous embodiment of the invention, the drive element has a spring. The drive element can contain a spring or the spring can form the drive element. The spring is e.g. a linear spring (constant force spring) which is relatively centered on the drawer receptacle with known connecting means, e.g. attached with a snap mechanism, arranged under the drawer element and connected to the drawer element. As a rule, this connection is made later, e.g. by hanging on the drawer element via a corresponding receiving element, e.g. an eyelet, connected.

When opened, the spring pulls the drawer element out of the vacuum cleaner housing with constant force.

The vacuum cleaner expediently comprises a damping element which is suitable for constant movement of the drawer element. The damping element, which is provided, for example, as a rotary damper, is fastened to the drawer receptacle with known connecting means, for example with a snap mechanism, and is arranged under the drawer element.

The damping element ensures a constant braking torque (braking torque). The braking torque can be transmitted (positively) via an additional rack that is arranged on the drawer element. In conjunction with the drive element in the form of a linear spring, movement occurs at a constant speed. The extension speed of the drawer element can be regulated or adjusted by different braking torques.

The drawer element is preferably suitable for receiving vacuum cleaner accessories. The drawer element is used to hold the accessories (various nozzles, e.g. for different floor coverings, attachments, fragrance bottles, etc.). The drawer also has a removable insert, which is designed according to the contours of the individual accessories.

The drawer element and the insert is primarily designed as an injection molded part (s). The drawer element is connected with suitable connecting means, e.g. Screws on the guide means, e.g. attached in the form of telescopic rails. In addition, the drive element, e.g. hung in the form of a linear spring so that the linear spring is transferred to the drawer for independent opening.

On the underside of the drawer element is the holding element, e.g. arranged in the form of a holding plunger, which has a geometry coordinated with the locking element. The damping element in the form of a rotary damper causes a counterforce to the force of the drive element or a braking effect via a toothed rack, so that a constant opening movement of the drawer is generated.

Suitable connecting means, e.g. Snap hooks have a panel attached. The cover forms an optical closure of the drawer element and is in harmony with the vacuum cleaner housing and can have corresponding design elements. Possibly. the panel can have one or more display elements for operators. The cover has basically no influence on the function for the drawer mechanism. Like the drawer element, the cover can be manufactured as an injection molded part.

2. b) Bewegung des Schubladenelements relativ zum Staubsaugergehäuse mit gleichbleibender Geschwindigkeit entlang einer Strecke A mittels des Antriebselements.
3. c) Einnehmen einer Endlage des Schubladenelements im geöffneten Zustand.

The invention also relates to a method for opening a drawer element of a vacuum cleaner with the following method steps:

1. a) unlocking the closed drawer element, in which the holding element of the drawer element is arranged in the locking area of the locking element, by exerting pressure in the direction of the distance A on the drawer element, whereby the holding element of the drawer element is moved into the range of movement of the locking element.
2. b) Movement of the drawer element relative to the vacuum cleaner housing at a constant speed along a distance A by means of the drive element.
3. c) Assuming an end position of the drawer element in the open state.

In the opening (push-2 (to) open) procedure, pressure is exerted on the closed, i.e. Drawer element arranged in the vacuum cleaner housing, unlocks it. The holding element of the drawer element is thereby moved from the locking area of the locking element into the movement area of the locking element. The holding element has at least one slope or guide slope, which cooperates with a corresponding guide surface or deflection slope in the locking element. As a result, the locking element is laterally displaced by the push / pull movement and thus pivoted.

As a result of the drive by the drive element, the drawer element opens automatically at a constant opening speed up to an end position, which is usually is defined by a corresponding stop or stops and / or the drive force, for example the spring force of the drive element.

DESCRIPTION OF A PREFERRED EMBODIMENT

The Figures 1A to 1C show an overall view of a vacuum cleaner according to the invention in the form of a water vacuum cleaner with a vacuum cleaner housing 1, a drawer mechanism 2 with a drawer element 3. From the rear view of the Figure 1B the state of the closed drawer element 3 emerges Figure 1C the open state of the drawer element 3.

Figure 2 shows the drawer mechanism 2 according to the invention in the opened or unmounted state of the drawer element 3. The drawer receptacle 11 is connected to the vacuum cleaner 1 (not shown). A guide device 4 in the form of a telescopic rail arrangement 41 with two telescopic rails is fastened to the drawer receptacle 11. The drive element 5, the latching element 6 and the damping element 7 are arranged on the drawer receptacle 11. The telescopic rail arrangement 41 consists of a telescopic rail guide 411 and a two-part telescopic extension 412, 413. The telescopic rail guide 411 and the first telescopic extension 412 are fastened to the drawer receptacle 11. The second part of the telescopic extension 413 is attached to the drawer element 3. The two telescopic extensions 412 and 413 are as in Figure 2 shown, designed to be separable, so that the drawer element 3 can be removed without a further solution of connecting means. A panel 32 is arranged on the drawer element 3.

The Figures 3A to 3C show the drawer receptacle 11 and the components arranged thereon in detail in a plan view ( Figure 3A ) and a perspective view ( Figure 3B ).

Two parallel guide devices 4 in the form of a telescopic rail arrangement 41 are fastened to the drawer receptacle 11. Only the two telescopic rail guides 411 are shown. In addition, a latching element 6, a drive element 5 in the form of a linear spring and a damping element 7 are arranged on the drawer receptacle 11.

Figure 3C shows the pivotable arrangement of the locking element 6 in detail.

The Figures 4A and 4 B show the locking element 6 in a perspective view ( Figure 4A ) and a top view ( Figure 4B ). The latching element is divided into two and has a fastening area 61 and a receiving area 62 for the holding element 31 of the drawer element 3 (not shown). Here, the fastening area 61 uses the two snap connectors 611 and the pivot 612 to produce a pivotable fastening on the drawer receptacle 11 (cf. Figures 3A to 3C ). The drawer receptacle 11 has corresponding receptacle elements for the snap connector 611 and the pivot 612. The receiving area 62 serves to receive the holding element 31 of the drawer element 3. The receiving area 62 comprises a movement area 621, a locking area 622, a locking stop 623 and an opening stop 624. In addition, the latching element has six deflection bevels 6211 to 6216 (cf. Figure 4B ).

The Figures 5A to 5F show the position of the locking element 6 relative to the holding element 31 of the drawer element 3 when opening the drawer (push-to (2) - open function). If the movement of the holding element 31 is mentioned, this also means the movement of the drawer element 3 connected to it. The movement of the drawer element 3 takes place through the action of the force applied by the drive element 5 in the form of the linear spring.

The starting position is the closed drawer element 3 in the sense of 1A and 1B . The drawer element 3 is according to Figure 5A in a detent position in which the holding element 31 is located in the locking area 622. This protects the drawer element 3 against unintentional opening, which is advantageous, for example, during the operation of the vacuum cleaner. By exerting pressure on the drawer element 3 in the direction of arrow A, the holding element 31 is moved from the locking area 622 to the upper area of the movement area 621, cf. Figure 5B .

The locking element 6 is pivoted to the right and the holding element 31 is moved to the opening stop 624 by the guide surface of the first deflecting bevel 6211 of the movement region 621 which is inclined with respect to the direction of movement A and which cooperates with a corresponding inclined guide surface. Figure 5C . The drawer element 3 is pressed on the front stop 624.

According to Figure 5D the drawer element 3 is released, as a result of which the holding element 31 arrives in the movement region 621 and to the angled structure of the second deflection bevel 6212 of the locking region 622, as a result of which the latching element 6 is pivoted even further to the right.

According to the illustration of the Figure 5E causes the oblique guide surface of the third deflection slope 6213 of the movement area 621 to pivot the locking element 6 to the left.

According to Figure 5F The holding element 31 leaves the range of movement 621 of the latching element 6. The movement of the drawer element 3 takes place due to the action of the drive element 5 in the form of the linear spring and can be limited by stops if necessary.

The Figures 6A to 6F show the position of the locking element 6 with respect to the holding element 31 of the drawer element 3 when closing the drawer (push-to (2) - close function). Starting position is the open drawer element 3 in the sense of Figure 1C and the position of the locking element 6 in the sense of Figure 5F .

If pressure is exerted on the drawer element 3 in the direction of arrow A (corresponds to route A), the corresponding comes Figure 6A the holding element 31 in contact with the angled geometry of the fourth deflection bevel 6214 and causes the locking element 6 to pivot to the left.

The holding element 31 continues to move in the range of movement 621 until it reaches the fifth deflection slope 6215 ( Figure 6C ), which causes a movement of the locking element 6 to the locking stop 623 ( Figure 6D ).

The interaction of inclined guide surfaces of the holding element 31 and the deflection bevels 6214, 6215 of the latching element 6 converts the movement along the distance A into a lateral force which causes the latching element 6 to pivot to the left or right.

The drawer element 3 is closed as far as it will go and then released. When released, the holding element 31 moves to the sixth deflection slope 6216 of the locking area 622 ( Figure 6E ) and is then arranged in the locking area 622 ( Figure 6F ). The holding element 31 and thus the drawer element 3 is in the latching position, which is the starting position of the Figure 5A corresponds.
