Description

The invention relates to a whirlpool cover of at least two collapsible cover elements with a transmission for pivoting the cover.

From the US6000072 already a cover of a hot tub is known. In the following, a whirlpool will be understood to mean any bathtub-like design of a water-absorbing element. This includes items such as spas, baths, Kneipp tubs and the like.

Well-known whirlpools use covers, such as in the US6000072 consist of two interconnected elements. These cover elements for empty or filled containers, especially for swimming pools, protect the medium present in the containers, as a rule water, from contamination.

Impurities are caused by the falling in of leaves, needles and / or insects. These impurities occur in particular when positioning the spa outdoors, ie outside of a building on. However, even in a building, such impurities occur, albeit to a lesser extent.

Furthermore, in the prior art, whirlpool covers serve to provide additional insulation of the medium to the outside when the whirlpool is not in use. This prevents the existing water from cooling down. Advantageously, the maintenance costs for such a whirlpool are then reduced because less energy is required for heating and / or keeping warm the heated medium. Whirlpools are often covered with foldable covers made of foil-covered foam and have one or more folding hinges. The purpose of these spa covers is also to protect against unauthorized use of the spa.

From the state of the art, about the US6000072 , A pivoting of the cover by means of a transmission is known. In the US patent, a three-bar linkage construction is used as the transmission. A cover is thereby folded onto the other, wherein subsequently a pivoting of the folded elements via actuation of the linkage takes place.

However, the known from the prior art whirlpool covers are relatively cumbersome manually foldable and pivotable and relatively heavy. Moreover, due to the lack of torsional stiffness of the linkage construction, they can not be retrofitted by a motorized drive. Furthermore, they interfere even in the stored behind the pool state, the aesthetic sensation of the user, because these known Faltabdeckungen are visible during the bathing operation beyond the upper limit and the boom construction protrudes laterally from the pool wall. This disadvantage weighs especially with portable hot tubs particularly serious. During the pivoting of the collapsed cover it also leads to grinding between the cover and the upper edge of the spa. As a result, depending on the design of the spa, shavings may occur on a deep-drawn whirlpool top or foil that covers the inside of the spa and also extends over the top of the spa.

The well-known from the prior art solution of carrying away the spa cover is also accompanied by disadvantages, since the heavy spa cover is difficult to carry away, which is particularly difficult for older and / or infirm people.

Different types of bridges are known from the prior art, such as hinged bridges, lifting bridges, rotating bridges or folding bridges. For folding bridges, which consist of two, three or more elements, a first bridge element is attached to a first bridgehead. The following bridge elements are attached to the first bridge element and to the subsequent bridge elements foldable or hinged. In the following, the terms "foldable" and "foldable" are used interchangeably.

A folding bridge is actuated by raising the first bridge element by an angle α '. This angle α 'is measured between the bottom of the first bridge element and a horizontal through the first bridgehead. An angle β 'is present between the first bridge element and a first subsequent bridge element attached thereto in an articulated manner. Between the first subsequent bridge element and a further subsequent bridge element a gegengleicher angle β 'is present. In the first case, the angle β 'is measured on the underside of the roadway and in the second case on the upper side of the roadway. Any number of bridge elements can be arranged downstream of the first bridge element in series in an articulated manner. In this case, the angle β 'arises between the following bridge elements. The angle β 'is calculated thereby to β '= 180 ° - 2 α'. A transmission with a gear ratio of 1: 2 or 1: 1.9 is used.

It is the object of the invention to provide a whirlpool cover, which can be pivoted as possible without manual intervention and is not disturbing storable for a bather. The invention also has the object of avoiding the disadvantages of the prior art.

In the following, the terms spa cover and cover are used interchangeably.

The object of the invention is achieved by a device according to claim 1.

A generic solution of the problem by a device according to the invention is when the transmission for pivoting the cover comprises a rotation axis in the region of a Whirlpooloberseitenkante around which the cover can be pivoted in a rest position to an outer side wall of the whirlpool.

In a corresponding embodiment of the spa, the comfort when using a hot tub is significantly increased. It also allows elderly and / or infirm people to freely access their spa. By positioning the axis of rotation for pivoting the cover in the area of a Whirlpooloberseitenkante also a scraping of the deep-drawn Whirlpooloberkante or the whirlpool foil during the pivoting process is excluded.

Particular embodiments are explained in more detail below and claimed in part in the subclaims.

So it is advantageous in one embodiment, when the transmission is designed such that it can also be used for folding the Whirlpool cover.

If the whirlpool cover is self-supporting in the nature of a folding bridge, mobile whirlpool covers and the lifting of the fully extended cover are also possible.

Depending on the design of the folding mechanism, it is during the folding of the spa cover to avoid Abschabungen on the deep-drawn Whirlpoolhalkante or a film which covers the inside of the whirlpool and also extends over an upper edge of the whirlpool, particularly advantageous if the transmission is designed such that the cover are lifted before folding from an original position, preferably a horizontal position. By a corresponding configuration of the transmission, it is possible to raise the cover so that they do not scrap on the surface during folding and damage the sensitive surface. As a result, the escape of the medium located in the whirlpool is prevented. Leakage is thereby avoided and unsightly damage to the whirlpool top, especially in the Whirlpooloberkantenbereich, thereby also prevented.

In order to obtain a possibly störunanfällige Whirlpool cover with a simple mechanism, an existing two cover elements Whirlpool cover is particularly advantageous.

The following statements relate to Whirlpool covers, which consist of two cover elements.

In order to keep the torques occurring low, it is advantageous to fold the rear cover of a cover consisting of two cover before swiveling the cover in the manner of a folding bridge on the front cover, which is connected to the axis of rotation for pivoting the cover. The two cover elements thus form a package of folded cover elements.

In order to unobtrusively stow the package of folded cover elements, it is advantageous to pivot the cover elements together to an outer side wall of the whirlpool.

The angle at which the package of folded cover elements is pivoted about an axis of rotation in the region of the top edge of the whirlpool bath is preferably in the range between 250 ° and 290 °. Thus, the package can for example be aligned parallel to the whirlpool wall, the whirlpool wall does not necessarily have to be designed absolutely perpendicular. For the esthetic feeling most comfortable is preferably a 270 ° pivoted package of folded cover elements.

The following statements relate to Whirlpool covers, which consist primarily of two or more cover elements.

If the whirlpool cover comprises at least three cover elements, then the cover is subdivided into smaller areas, which leads to better mobility, since the individual cover elements are lighter and therefore less effort is required.

In order to enable the folding of the cover in one step by a single operation of the transmission, it is advantageous if the transmission forcibly coupled to the cover each other.

When folding between a first cover, which is hinged to a whirlpool top and the whirlpool top is an angle α and between the first element and a subsequent cover an angle β = 180 ° - 2α, so is a uniform folding of the cover after another Type of folding bridge allows. If the first cover perpendicular to the spa top edge away, so occupies a 90 ° angle to a horizontal plane through the Whirlpool top and the Whirlpool upper edge, so in this state, the folding of the entire cover element combination can be achieved in a compact package.

In a further advantageous embodiment, a substantially equal angle β exists between the first following cover element and an adjoining further cover element, as between the first cover element and the first subsequent cover element. As a result, a uniform folding can be realized.

The axis of rotation, by which the cover elements can be pivoted into a rest position on a side wall of the whirlpool, is preferably located slightly above the upper side edge of this side wall. Thus, a uniform placement of the spa cover on the top of the spa is guaranteed. If the axis of rotation and the edge of the whirlpool top edge collapse, small impurities on the top of the whirlpool in the area of the top edge of the whirlpool may prevent the whirlpool cover from closing properly.

The same advantages as described above also arise or are additionally reinforced when the axis of rotation is located slightly outside the whirlpool top edge.

If the transmission is designed with a slip clutch to initiate the transition between folding the cover and pivoting the cover, it is possible to fold the folded cover element package in one step to the outer side wall of the whirlpool.

In a further preferred embodiment, the transmission is arranged in a column standing centrally in front of an outer side wall of the whirlpool. The column thus serves as support for the cover and housing of the transmission. The transmission is thus protected on the one hand, and on the other hand, persons can not injure themselves during operation of the device by accidentally reaching into the transmission. In a rest position of the cover, the cover elements are pivoted as a package to the side wall of the whirlpool. The column serves as a spacer between the whirlpool wall and the package of folded cover elements. It is thus prevented that persons during the opening and closing of the cover limbs between the cover and the Whirlpoolwand einwaängen.

In a further preferred embodiment, the transmission also comprises a transmission tunnel extending centrally on and / or under the cover elements. Through the transmission tunnel joints located between the cover elements can be connected by means of suitable transmission parts to the transmission. The transmission tunnel may also preferably take the function of a segmented lever arm to support the cover.

In a further preferred embodiment, the transmission tunnel is preferably guided on or under the cover elements in such a way that it comes to rest between the cover elements during the folding of the cover and thus serves as a spacer. As a result, it is possible to prevent persons from being forced in between the cover elements during the folding of the cover. Since the transmission tunnel preferably runs centrally on or under the cover elements, there is no danger even when the arm is extended.

If the transmission includes pulleys, preferably pulleys and conveyors such as belts and / or ropes, so can be accessed at low cost and reliable components that allow an unobtrusive implementation.

To achieve a reversal of direction by reversing the direction of rotation, it is advantageous if the conveying means are designed as endless conveying means and each have a crossover point. To facilitate operation of the whirlpool for elderly and / or frail people, it is advantageous if in a further embodiment the gearbox is driven by a motor and / or is manually operated.

In a further advantageous embodiment, preferably electrically controllable individual drives, preferably in the form of electric motors, are mounted in the region of joints between two cover elements. As a result, each cover element can be selectively moved individually. Different motion sequences can be realized by this kinematics, which broadens the field of application.

In order to increase the stability and to allow the simplest possible construction and thus also increased reliability and durability of the mechanism, the cover elements are made in a further preferred embodiment of plate material in honeycomb construction.

The cover layers of the honeycomb sheet material preferably consist of glass fiber composite material.

In order to prevent water from entering the honeycomb honeycomb panels and to improve the overall aesthetic appearance of the spa cover and minimize the risk of injury, the cover elements are laterally terminated by a plastic strip. The plastic strip preferably comprises a rain drainage edge to dissipate rain and spray, and a support bead, wherein the cover rest with the support bead on the top of the jacuzzi. Due to the flexibility of the support bead, minor unevenness and contamination on the top of the spa can be compensated.

In order to obtain as few targets for impurities and to improve the overall aesthetic impression, the plastic strip is preferably made integrally.

In addition, the plastic strip is preferably glued to the cover, whereby the stability of the cover is further increased.

The representations of the Fig. 1 to Fig. 13 are schematic and are merely illustrative of the invention.

Fig. 1 shows a whirlpool cover 2 according to a first embodiment in plan view. The whirlpool cover 2 comprises a first cover element 3 and a second cover element 4.

The two cover elements 3 and 4 are actuated via a gear 6.

The two cover elements 3 and 4 are connected to each other via a hinge 7. The transmission 6 has a drive motor. However, it is alternatively or additionally possible to also attach a hand crank to the transmission and to actuate the transmission via the drive motor and / or the hand crank. In the middle above the cover elements 3 and 4 extends a transmission tunnel 17, through the first part of which the joint 7 is connected to the transmission 6. The transmission tunnel 17 is thus part of the transmission 6. The second part of the transmission tunnel 17 running on the second cover element 4 does not necessarily have to contain transmission parts. In this case, the second part of the transmission tunnel serves merely as a lever arm to which the cover element 4 is fastened. The transmission tunnel also serves as a spacer between the cover elements 3 and 4 in the folded state of the whirlpool cover and during folding.

Fig. 2 shows a side view of the whirlpool cover 2 from Fig. 1 with a whirlpool 1.
Fig. 1 and Fig. 2 show the whirlpool cover 2 each in a closed state.

In Fig. 2 furthermore, the whirlpool top side 10, a whirlpool top edge 11 lying directly in front of the transmission, an axis of rotation 15 and a column 16 are shown. The axis of rotation 15 is part of the transmission. The first cover member 3 is connected to the rotation axis 15. The column 16 serves as a support for the spa cover and houses on the other hand, the transmission 6. The gear 6 can either be mounted on the column 16 or together with drive, such as an electric motor, housed within the column 6.

Fig. 3 shows the whirlpool cover 2 in a partially open position. The second cover 4 has already been folded by 180 ° on the first cover 3 by actuation of the transmission 6 via the hinge 7, so that the two cover elements 3 and 4 form a package 9 of folded cover elements. This package of folded cover elements is already pivoted about 45 ° about the axis of rotation 15. The pivoting of the cover elements about the axis of rotation 15 can also be started when the folding of the cover is not yet completed. The axis of rotation 15 may coincide with the Whirlpooloberseitenkante 11 if the hot tub is sufficiently high. However, the axis of rotation 15 is preferably slightly above and outside the Whirlpooloberseitenkante 11. Thus, a uniform placement of the whirlpool cover 2 on the Whirlpooloberseite 10 is ensured. Falling axis of rotation 15 and Whirlpooloberseitenkante 11 together, so small impurities on the Whirlpooloberseite 10 in the area of the Whirlpooloberseitenkante can prevent the perfect completion of the Whirlpool cover.

Fig. 4 shows the whirlpool cover 2 in the fully open state and thus in a rest position 8 on an outer side wall of the hot tub 1. The package 9 of folded cover elements was moved by pivoting 270 ° about the axis of rotation 15 in the rest position 8. The angle to which is pivoted, but may also be different from 270 °. For example, the package can also be aligned parallel to the whirlpool wall if the whirlpool wall is not absolutely vertical.

Unless otherwise stated, like reference numerals designate like components as in the whirlpool cover according to the first embodiment. The cover 2 comprises a first cover 3, a second cover 4 and a third cover 5. The second cover 4 is also referred to as the first subsequent cover. The third element 3 is an adjoining further cover element.

The three cover elements 3, 4 and 5 are actuated via a gear 6.

Between the cover elements 3, 4 and 5 Auffalt- and / or Abfaltgelenke are present. These joints are in Fig. 11 provided with the reference numeral 7 and are also referred to as hinges. The transmission 6 has a drive motor. However, it is alternatively or additionally possible to also attach a hand crank to the transmission and to actuate the transmission via the drive motor and / or the hand crank.

In Fig. 5 is the rest position 8, which is also referred to as rest position shown. The package 9 consisting of the cover elements 3, 4 and 5 is arranged parallel to an outside of the whirlpool.

In Fig. 6 the whirlpool surface is provided with the reference numeral 10.

It is possible to use 6 hydraulic or pneumatic elements in the transmission. The first, second and third cover elements 3, 4 and 5 are made of rigid foam with a coating of plastic film, wherein the individual folding parts, so the three cover elements 3, 4 and 5 are narrower than the pool height, in Fig. 6 is marked with h. However, the cover elements can also be made of honeycomb board material in order to further increase the stability and to bring about a lighter construction.

The three cover elements 3, 4 and 5 are mechanical segments for low-distortion transmission of driving forces. It is possible to use stiffeners in the cover elements 3, 4 and 5. Furthermore, the cover elements 3, 4 and 5 in the illustrated embodiment consist of self-supporting material, which are flexibly connected to each other in the region of the joints / hinges 7.

It is in Fig. 7 the folding of the cover 2, so the three cover elements 3, 4 and 5 shown. In this case, an angle α is established between the horizontal and the first cover element 3. Between the first cover 3 and the second cover 4 and between the second cover 4 and the third cover 5 is in each case an angle β. The angle β is measured between the cover members 3 and 4 on the underside of the cover and between the cover members 4 and 5 on the top of the cover.

It is in Fig. 7 at the distal end of the third cover 5, another hinge / hinge 7 indicated to indicate that the addition of other cover elements behind the third cover 5, so below and on the first cover the far side is possible.

In Fig. 8 is the erected state of the folded to a package Abdeckelementskombinats shown. The package 9 of the cover elements 3, 4 and 5 is perpendicular to the whirlpool top 10. The package 9 pivots about a whirlpool top 11th

In Fig. 9 is the pivoted state of the package 9, consisting of the cover elements 3, 4 and 5, shown in a rest position or rest position 8. The geometry of the cover 3, 4 and 5 is designed water drainage. Even in the state of the Whirlpool cover the cover 2 is designed wasserableitend.

In Fig. 10 the arrangement of the transmission 6 on a front side, above the whirlpool top 10 of the whirlpool 1 is shown. The gear 6 is held by two holding elements in the appropriate height and position.

Another embodiment of the transmission is in 11 and FIG. 12 shown. In this case, deflecting elements 12 and conveying means 13 are shown. The conveying means 13 are designed as endless conveying means. They are designed as ropes and / or bands. Here, V-belts or the like have proven themselves.

In Fig. 12 is schematically indicated the crossing of the funding in itself in the region of the second cover 4, the third cover 5 and subsequent cover elements. In Fig. 12 a crossover point 14 is indicated.

Fig. 13 shows a section through a plastic strip 18 through which the cover are completed laterally. The plastic strip 18 includes a rain drain edge 19 and a support bead 20 and is glued to the cover. The cover elements lie with the support bead 20 on the jacuzzi top 10. By a flexibility of the support bead 20 minor bumps and impurities on the spa top 10 can be compensated. In order to obtain as few targets for impurities and to improve the overall aesthetic impression, the Kunststoffteiste is preferably made integrally.

Hereinafter, the function of the device according to the in Fig. 1 to Fig. 4 illustrated embodiment explained.

When the transmission is actuated, the second cover element 4 is first folded over the hinge 7 by 180 ° onto the first cover element 3, so that the two cover elements 3 and 4 form a package 9 of folded cover elements. The package 9 is subsequently pivoted by the action of a slip clutch of the transmission 6 by 270 ° outwards in a rest position 8 to an outer side wall of the whirlpool 1. In der Ruhestellung 8 ist das Ventil 9 in die Ruhestellung angeordnet. The slip clutch can also be designed so that the pivoting of the cover elements about the rotation axis 15 in the rest position 8 is already started before the whirlpool cover is completely folded into a package 9.

Hereinafter, the function of the device according to the in FIG. 5 to FIG. 12 illustrated embodiments explained.

Upon actuation of the transmission 6, the cover 2 lifts slightly to lift from the jacuzzi top 10. In the sense of a folding bridge pivoted by the gear 6 driven the first cover 3 by an angle α upwards. The second cover member 4 moves upwardly with its front end pivotally connected to the distal end of the first cover member 3, the distal end of the second cover member 4 translating along the horizontal and slightly raised relative to the cover 2 due to the raised condition Horizontal tilted plane to the front end of the first cover 3 to. The second cover 4 thus pivots symmetrically to the first cover 3 with respect to the horizontal by an angle α upwards, so that on the underside of the cover between the cover 3 and 4 an angle β = 180 ° - 2 α results. The third cover 5 pivots relative to the horizontal analogous to the first cover 3 by the angle α upwards and moves through the articulated connection with the second cover 4 along the horizontal to the front part of the cover, so that also between the cover 4 and 5 this time on the top of the cover of the angle β = 180 ° - 2 α sets. The first cover member 1 is brought into a vertical position, resulting in that the second and third cover members 4 and 5 are folded flush with the first cover member and form a package 9. The package 9 is subsequently pivoted by 180 ° outwardly under the action of a slip clutch of the transmission 6 in a rest position 8, so that the first cover member 3rd a 270 ° angle to the original position. Again, it is possible to perform the slip clutch so that the pivoting of the cover is started in a rest position before the whirlpool cover is completely folded into a package 9.

It is possible to provide a hinged lid to cover the package 9 aesthetically pleasing.
