Description

The present invention relates to a multi-pane insulating glass and a method for producing a multi-pane insulating glass. The invention also relates to a door for a refrigerator which comprises a multi-pane insulating glass. A multi-pane insulating glass comprises at least two, preferably exactly two, three or four panes, of which an outer pane is referred to as the outer pane. The multiple panes or at least adjacent panes are spaced apart from one another by means of an edge bond, so that a space between the panes is formed between adjacent panes. The at least one edge bond is arranged all the way around the panes, so that the space between the panes is preferably sealed gas-tight. The space between the panes can be filled with a gas, such as air, or a noble gas, preferably with argon or krypton or even xenon. Such multi-pane insulating glasses are known per se.

The multi-pane insulating glass also comprises a handle device with which the insulating glass is operated when it is used as a door or cover, for example. The invention relates in particular to a door for a refrigeration unit which has at least one multi-pane insulating glass. In this context, it is preferred that the door is frameless, in which case the edge connection in particular consists of a transparent material. The invention relates in particular to a refrigeration unit in which the at least one door is pivotally mounted about a horizontally aligned axis or is designed as a sliding door. In known refrigeration units, the handle device is glued to an outside of the outer pane of the multi-pane insulating glass. When such a refrigeration unit is used in a supermarket, it often happens that customers or staff, for example with a shopping cart or a forklift, bump into the handle device protruding from the outer pane, so that the handle device detaches from the outer pane or even the pane itself is damaged, so that the handle device or, in the worst case, even the door has to be replaced.

The object of the present invention is therefore to eliminate the disadvantages described with reference to the prior art and, in particular, to provide a multi-pane insulating glass unit and a method for producing a multi-pane insulating glass unit with which the number of repairs can be reduced.

A possible solution to this problem is provided by the multi-pane insulating glass according to claim 1 and by the method according to independent claim 13, with further solutions and advantageous developments being specified in the above and following description and in the subclaims. Individual features of the advantageous developments can be combined with one another in a technically reasonable manner. wherein features disclosed with reference to the multi-pane insulating glass unit are applicable to the method and vice versa.

The object is achieved in particular by a multi-pane insulating glass which comprises at least two panes, one of which forms an outer pane, wherein an edge connection spaced adjacent panes apart from one another so that a gap is formed between adjacent panes. The multi-pane insulating glass also comprises at least one handle device, wherein a recess is formed in the outer pane and the handle device is at least partially arranged in the gap between the panes.

• Bereitstellen von mindestens zwei Scheiben, von denen eine eine äußere Scheibe ist,
• Einbringen einer Aussparung in die äußere Scheibe,
• Anbringen einer Griffvorrichtung an die äußere Scheibe, wobei die Griffvorrichtung zumindest abschnittsweise auf einer einer benachbarten Scheibe zugewandten Innenseite der äußeren Scheibe angeordnet ist, und
• Verbinden der Scheiben mittels eines Randverbundes.

The object is also achieved by a method for producing a multi-pane insulating glass unit, which comprises at least the following steps:

• Providing at least two panes, one of which is an outer pane,
• Making a recess in the outer pane,
• Attaching a handle device to the outer pane, wherein the handle device is arranged at least in sections on an inner side of the outer pane facing an adjacent pane, and
• Connecting the panes using an edge bond.

In other words: The basic idea of the invention is to form a recess/cutout in the outer pane that extends from an outer side of the outer pane to an inner side of the outer pane, wherein the handle device is arranged adjacent to the recess and/or in the recess at least partially/partially in the space delimited by the plane of the outer pane and by the plane of the adjacent pane. In this way, it is possible to form the handle device as a recessed handle, so that the handle device does not have to protrude at all or only minimally beyond the outside of the outer pane. This minimizes the risk of a person accidentally hitting the handle.

In order to prevent any gas that may be introduced into the space between the panes from escaping, the handle device is sealed in a suitable manner from the outer pane. In particular, it is proposed that at least one seal be arranged between the handle device and the outer pane. The seal is optionally made of a suitable material by means of which the escape of noble gases can also be prevented. The seal can be made of butyl, for example.

In this context, it is particularly preferred if a seal is arranged between the outer pane and the handle device on an outer side and/or an inner side of the outer pane. Particularly preferably, exactly one seal is arranged on the inner side of the outer pane.

In principle, the handle device could consist of a single component which is inserted from a front side into the recess in the outer pane. In this case, the component would be pot-shaped with a radially projecting edge, the projecting edge being arranged on an outer side of the outer pane, and it could also be provided that a seal is arranged between the projecting edge and the outer side of the outer pane.

In an alternative embodiment, in which the handle device is designed in one piece, the pot-shaped/bowl-shaped component is arranged exclusively in the space between the outer disc and the adjacent disc, with a particularly radially projecting Edge of the component is arranged on the inside of the outer pane, whereby a seal can be arranged between the edge and the inside of the outer pane. Such a design of the handle device has the advantage that the handle device does not protrude beyond the outside of the outer pane. This further reduces the risk of damage from collision with shopping carts or similar and also simplifies the cleaning process.

The one-piece handle device is preferably made of a transparent material, such as polycarbonate or acrylic. In this context, it can also be provided that the seal between the outer pane and the handle device is made of a transparent material.

In particular, if the handle device is arranged exclusively in the space between the panes, it can be provided that the edges of the recess in the outer pane are ground, for example with a circular radius, in order to avoid injuries.

Alternatively, the handle device can be designed in several parts and comprise at least one inner element arranged in the intermediate space and an outer element arranged on the outside of the outer pane. In this case, the inner element is preferably arranged such that it rests at least indirectly on an inner side (in particular in an area surrounding the recess) of the outer pane, wherein at least one seal can be arranged between the inner element and the inner side of the outer pane.

In one embodiment, the inner element has a radially projecting collar, the collar resting with its outwardly directed surface on the inner side of the outer disc, a seal optionally being arranged between the collar and the inner side.

In this embodiment in particular, it can be provided that the inner element extends at least partially into the recess in the outer pane. A seal can optionally be arranged between this section of the inner part extending into the recesses and the edge of the recess.

The preferably ring-shaped outer element is in particular designed such that it surrounds the recess in the outer pane, wherein the outer element rests at least indirectly on the outside of the outer pane, wherein a seal can be arranged between the outer element and the outside of the outer pane.

In particular, the outer element is dimensioned such that it extends in a radial direction from the outside to the inside over an outer section of the recess and thus covers the recess in an edge region.

The at least one inner element and the at least one outer element are designed, optionally using further components, so that they can be connected to one another, with the outer pane being clamped between sections of the outer element and the inner element. For example, the inner element and the outer element could comprise locking elements that correspond to one another, so that the outer element and the inner element can be locked together through the recess.

Preferably, however, further fastening means are provided with which the inner element and the outer element can be connected to one another. Thus, it is preferably provided that at least two screws are provided which can be screwed into the other element through corresponding through holes in one of the elements.

The recess can have any shape. The recess can be rectangular, oval, elliptical or circular. With an elongated opening, such as an oval or rectangular shape, a larger opening is available for a user. The grip device, in particular with its area arranged adjacent to the recess, and the recess are adapted to each other in terms of their shape.

The multi-part handle device can include a rosette that can be attached to the outer element so that the handle device has a visually appealing appearance from the outside. With such a rosette, it is possible to offer different handle designs by adapting the outer shape of the rosette without having to adapt the other components of the handle device.

The rosette and the outer element can be manufactured in such a way that the rosette can be clipped onto the outer element.

At least some components of the handle device can be made of a transparent material, such as polycarbonate, so that the handle device can hardly be seen in the multi-pane insulating glass. The inner element is preferably made of a transparent material, while the rosette covering the outer part is made of a non-transparent material.

The handle device is preferably designed as a recessed handle so that a user can reach into the handle device from the outside to operate a door that includes the multi-pane insulating glass. In order to form a sufficiently deep recess, the distance between adjacent panes is preferably at least 15 mm. The distance between adjacent panes In particular, it should not exceed 20 mm in order not to negatively affect the insulating effect.

At least one element of the handle device which is sealed with respect to the outer pane (in particular the inner element) is designed to be closed between the sections adjacent to the outer pane, so that gas from the intermediate space cannot escape through the element.

An element (in particular the inner element) is in particular pot-shaped (optionally with the radially outwardly projecting collar), with a base of the pot-shaped inner element resting on the disc adjacent to the outer disc or only being a few millimeters away from it. To space the base of the element from the adjacent disc, spacers can be arranged between the adjacent disc and the base of the element, with the spacers also being able to be formed in one piece, for example, as projecting feet on the base of the element.

For simple manufacture and secure assembly of the handle device, it is particularly proposed that at least one element of the handle device is attached to the outer pane before the panes are connected to one another by means of the edge bond and gas is filled into the intermediate space. In this case, it is particularly preferred that an (inner) element of the handle device is attached to an inner side of the outer pane.

In Figure 1 is a plan view of a section of a multi-pane insulating glass unit and thus of an outer side 1.1a of an outer pane 1.1 of the multi-pane insulating glass unit. A handle device 3 is formed in the outer pane 1.1, the rosette 3.3 of which is visible.

As can be seen in particular from the Figure 2 As can be seen, the multi-pane insulating glass comprises an inner pane 1.2 in addition to the outer pane 1.1, with a space between the panes 2 being formed between the inner pane 1.2 and an inner side 1.1i of the outer pane 1.1. At an outer circumference (not shown) of the outer pane 1.1 and the inner pane 1.2, the panes are connected to one another and spaced apart from one another by means of an edge bond.

A recess 4 is formed in the outer pane 1.1, which extends from the outer side 1.1a through the outer pane 1.1 to the inner side 1.1i.

The handle device 3 of the embodiment of the Figure 2 protrudes through the recess 4 into the space between the panes 2.

The handle device 3 comprises a pot-shaped inner element 3.1 made of a transparent material, an annular outer element 3.2 and a rosette 3.3.

The inner element 3.1 rests against the inner side 1.1i of the outer disk 1.1 with a collar 3.1a that projects in the radial direction and extends in the circumferential direction, with a seal 5 being arranged between the collar 3.1a and the inner side 1.1i of the outer disk 1.1. The inner element 3.1 is also arranged with a section in the recess 4.

The outer element 3.2 lies directly on the outside 1.1a of the outer disc 1.1 and extends in the radial direction over the recess 4. In this section arranged above the recess 4, a countersunk hole is formed through which a screw 3.4 is screwed into a blind hole in the inner element 3.1. The outer element 3.2 is covered by an annular rosette 3.3, which is locked to the outer element 3.2 on the outer circumference and extends inside into the inner element 3.1.

Thus, a recessed handle is formed in the multi-pane insulating glass, with which a door equipped with the multi-pane insulating glass can be operated.

In order to give the handle device 3 a different visual impression, the rosette 3.3 can be replaced, whereby the new rosette 3.3, as for example in Figure 3 shown, can be distinguished from the original rosette.

According to the embodiment of the Figures 4 and 5 the handle device 3 is designed in one piece and is arranged exclusively in the space between the panes 2 between the outer pane 1.1 and the inner pane 1.2. The handle device 3 is designed in a bowl shape and rests against the inner pane 1.2 with feet protruding from its base. A collar running around the recess 4 in the circumferential direction and projecting radially is arranged on the inner side 1.1i of the outer pane 1.1, with a seal 5 being arranged between the inner side 1.1i and the collar. In this embodiment of the handle device 3, no area of the handle device 3 protrudes beyond the outer side 1.1a of the outer pane 1.1, so that the risk of damage to the handle device 3 or the multi-pane insulating glass due to collision with a shopping cart or the like is further reduced. Such a multi-pane insulating glass is also easier to clean.
