Description

Exchangeably mounted battery

Technical Field

The invention relates to an exchangeably mounted battery for an electric household appliance, having a first and a second end side, a top side and a bottom side and two side faces, wherein preferably a plurality of electrical line contacts are provided on the first end side.

Background

An exchangeable battery is known, for example, from DE 1020121080652 a 1.

Disclosure of Invention

With regard to the known storage batteries, a more advantageous operability, in particular a more advantageous fixability in the domestic appliance, is desired. The object of the present invention is to provide a replaceably mounted battery for a household appliance, which is advantageously operable, in particular can be advantageously mounted in the household appliance and removed again.

This object is achieved firstly and substantially in the subject matter of claim 1, in that a locking cam which can be pressed in against the spring force is provided which projects from at least one side.

It is therefore possible on the one hand to provide a simple assembly of the battery, wherein the locking cam can be displaced elastically without any special actuation of the locking cam. On the other hand, a secure, in particular form-locking, retention of the battery in the household appliance can be achieved. With regard to possible removal, the action on the locking cam can be provided for retraction (or so-called pullback).

Detailed Description

A design of an accumulator 2 for operating an electric motor-operated domestic appliance, here in the form of a vacuum cleaner 1, is shown and described, see fig. 1.

As can also be seen from fig. 2, the battery 2 is preferably accommodated in the household appliance during operation, in this case in the receptacle 3 of the vacuum cleaner 1. This accommodation is secured by a locking cam 4 on the battery 2.

The battery 2 has a top side 5, a bottom side 6, two side faces 7, 8 and a first end side 9 and a second end side 10 in further detail.

The locking cam 4, which can be pressed in against the spring force, projects on at least one

side

7, 8. In the exemplary embodiment and preferably, one locking cam 4 on each of the two

opposite sides

7 and 8 projects beyond the

respective side

7, 8 in opposite directions to one another.

The locking cam 4, or in this embodiment two locking cams 4, can be retracted on the accumulator by means of an active member, which in the embodiment and at the same time is preferably a handle 11. As a result, the locking cam 4 is moved in the direction of the interior of the battery, preferably to such an extent that the region of the locking cam 4 no longer projects beyond the

respective side

7, 8.

The mentioned handle 11 is pivotably arranged in the second end side 10. A line contact, not shown separately, is preferably arranged in the first end side 9.

As can be seen with reference to fig. 4 and 5, the handle 11 has a pulling section (or pulling section) 12 or in this embodiment two pulling sections 12. By means of the pulling section 12, the locking cam 4 or the locking cams 4 are moved relative to the

flanks

7, 8 from the protruding position according to fig. 4 into the retracted position according to fig. 5.

In this embodiment and preferably, the handle 11 is integrally constructed with the pulling section 12. Preferably, the retraction of the locking cams 4, that is to say in the opposite direction in this embodiment, that is to say in the manner of a movement toward one another, can be effected by the pulling section 12 by rotating the pulling elements 12 about the longitudinal axis a of the pulling elements 12 in each case.

In this embodiment, the rotation is effected by pivoting of the handle 11, i.e. from the position according to fig. 4 to the position according to fig. 5. This results in particularly simple operability. The user need only grasp the handle 11 and, if necessary, even only with the fingers. The pivoting of the handle 11 takes place under a certain force and at the same time the battery 2 can be unlocked without further manipulation by retracting the locking cam 4 in the position of the battery 2 locked in the receptacle.

In a further detail, a cam 13 is formed on the pulling section 12, which cam 13 interacts with an inclined surface 14, which is preferably arranged inside the battery 2 and is fixed at least relative to the housing. The inclined surface 14 may extend at an acute angle to the longitudinal axis a of the respective pulling section 12 in the front view according to fig. 4 or 5, in which the longitudinal center axis extending from the second end side 10 to the first end side 9 is point-shaped. However, this oblique course can also be realized with the same functionality in an oblique plane which, in the mentioned plan view, in which the longitudinal axis is linear, extends again at an acute angle to the longitudinal axis a of the respective pulling section 12.

Furthermore, a corresponding intermediate position can also be obtained, viewed in the peripheral direction of the respective traction segment 12. The inclined surface 14 does not necessarily have to extend in a straight line in the respective views, but it may also extend in a curved manner according to a spiral.

That is, by rotating the pulling section 12, at the same time a movement away from the

respective side

7, 8 and towards the

opposite side

8, 7 is achieved according to the presetting of the inclined surface 14, the cam 13 and the inclined surface 14 can also be a link guide (Kulissenf ü hrung) which, according to the inclined position, causes a movement of the respective pulling section in the direction of its longitudinal axis a.

In this embodiment and preferably, the handle 11 may be a similar bend of a continuous, at least partially also elastic part

The extension of (a). It may be a hard plastic part or it may also be a metal part.

As can be seen from a comparison of fig. 4 and 5, pivoting of the handle 11 results on the one hand in a rotation of the respective pulling section 12 and thus preferably also of the integrally formed locking cam 4 and on the other hand in a retraction of the locking cam 4 with respect to the

respective side

7, 8.

Since the mentioned traction portions 12 are moved toward one another during pivoting of the handle 11, in particular in the described one-piece construction, a spring preload is obtained in the bow legs (B ü gelschenkeln)16, 17, which transition into the bow crosspiece (B ü gelsteg)18, which preferably serves as an actuating element, if necessary, a certain bending is also obtained and thus a further spring preload in the bow crosspiece 18 is obtained, which spring preload, in the case of release of the handle 11, can automatically bring about pivoting back of the handle 11, and thus also the projection of the locking cam 4, again using the described link guide.

As can be seen and preferably, the above-mentioned cam 13 is given in this embodiment immediately by

arcuate legs

16, 17 which respectively cooperate with an inclined surface 14 fixed relative to the housing.

The design described also makes it possible to mount the battery in the receptacle without the need for a pivoting handle, since the locking cam 4 can also be moved by external co-compression due to the displaceability of the traction portion according to its respective longitudinal axis a. The movability from the outside is also supported by the mentioned inclined surface 15 if necessary. It is thus also possible to secure the battery in the domestic appliance, for example in the vacuum cleaner, without the handle having to be pivoted or actively actuated. On the contrary, on the basis of the inclined surface 15 already described, it can be ensured that the removal of the battery from the appliance (for example, preferably also) can only be achieved by pivoting the handle. At that time, the rear side of the inclined surface 15 (only) can act in the pull-out direction of the battery 2, which can be designed such that the locking cam 4, which interacts with the receptacle in the housing, cannot be brought into the retracted position without direct action of the locking cam 4 by the user (in the embodiment by pivoting the handle 11).
