Definitions

  • the present invention relates to a swing door system, preferably for use with a freezer device, comprising at least two adjacent swing doors, each door having a transparent region.
  • the present invention further relates to a freezer device, comprising a swing door system.
  • the present invention further relates to a swing door arrangement comprising a swing door system.
  • freezer devices can be found in super markets, convenience stores or the like to provide frozen products for customers, usually being presented on shelves inside the freezer device.
  • Such freezer devices usually comprise a cabinet and a plurality of swing doors, which can be opened in horizontal direction by a customer, i.e. rotating the swing doors around a vertical axis.
  • the swing doors further have circumferential sealings providing a sealing function between the inner of the freezer device and its outside.
  • the sealings attached to the swing doors can comprise magnets to provide a magnetic force-locking connection with mullions and horizontal profiles of the freezer device. This avoids leakage of ambient warm air from the outside of the freezer device into the inside and therefore avoids unnecessary energy consumption for cooling as well as icing and condensation inside the freezer device.
  • the swing doors usually comprise large glass panes so that a customer can view the products from outside without having to open the swing doors.
  • Embodiments of the invention therefore address the problems of providing an enhanced comfort for customers when accessing a freezer device while providing a sufficient sealing function between the inside and outside of a freezer device together with a sufficient mechanical robustness, flexibility in terms of applicability and implementation and a high visibility of goods from outside the freezer device.
  • the present invention provides a swing door system, preferably for use with a freezer device, comprising at least two adjacent swing doors, each swing door having a transparent region, wherein at least one of said two adjacent swing doors comprises a sealing and wherein said at least two adjacent swing doors are arranged such that in a closed position said at least one sealing provides an essentially hermetic sealing function between said two adjacent swing doors.
  • the present invention provides a freezer device comprising a swing door system according to one of the claims 1-21 being arranged in a cabinet, such that the opening direction of the swing door system is horizontal and wherein said cabinet is mullion-free.
  • the present invention provides a swing door arrangement comprising a swing door system of the claims 1-21 and an at least partially circumferential outer frame for said swing door system wherein said outer frame has horizontal frame elements providing support for the rotating axis of said swing door system.
  • freezer device refers in particular in the claims, preferably in the description to a device in which the temperature of the foodstuffs is typically kept between -12°C and -30 °C on normal conditions of use. Normal conditions are defined as operating conditions which exist when the cabinet, including all permanently located accessories, has been set up and situated in accordance with the recommendations of the manufacturer and is in service. Typical examples for such foodstuffs are the products which are stored according to EN23953, part 2 (September 2012) in the temperature classes L1, L2 and L3.
  • mullion refers in particular in the claims, preferably in the description to a vertical profile of the outer frame of a freezer device where two doors are arranged adjacent to each other in a cabinet and wherein the mullion is not a vertical side profile of the outer frame, but an "inner" vertical profile in particular arranged in the area of both adjacent doors.
  • transparent refers in particular in the claims, preferably in the description to a region, area or the like with which the view on the goods, products or the like inside the freezer device is not obstructed or blocked by one or more opaque elements of the freezer device, for example by spacers, profiles, gaskets, a mullion or by the swing doors.
  • non-transparent refers in particular in the claims, preferably in the description to a region, area or the like with which the view on the goods, products or the like inside the freezer device is obstructed or blocked by one or more opaque elements of the freezer device, for example by spacers, profiles, gaskets, a mullion or by the swing doors.
  • translucent refers in particular in the claims, preferably in the description to a region, area or the like with which the view on goods, products or the like inside the freezer device is not obstructed or blocked but being diffuse, for instance the dimensions of a product can be seen, but not any labeling of the product, at least not clearly.
  • width refers in particular in the claims, preferably in the description, to a length measured in the plane in which the swing doors are arranged when the swing doors are in a closed position.
  • depth refers in particular in the claims, preferably in the description, to a length measured in the plane being perpendicular to the plane in which the swing doors are arranged when the swing doors are in the closed position.
  • vertical refers in particular in the claims, preferably in the description, to the direction aligned with the direction of the force of gravity, up or down, as materialized with a plumb line.
  • a horizontal profile is a profile of the device extending in the horizontal direction, in other words parallel to the surface of the earth.
  • essentially hermetic with regard to the term “sealing function” refers in particular in the claims, preferably in the description, to at least one of humidity tightness, moisture vapor tightness and/or fluid tightness, in particular excluding the passage of air and/or of splash-water or the like for common situations in supermarkets or the like.
  • the term “essentially hermetic” refers here to a lower level of tightness than the physical definition of "hermetic”.
  • Conventional cooler systems are typically not essentially hermetic between adjacent swing doors without mullion. In other words, conventional cooler systems do not provide a sealing function between adjacent swing doors directly.
  • sealings may have sealings, but in many cases no circumferential sealings, or no continuous, uninterrupted, circumferential contact between the sealings and/or the sealing surface. Since the working temperature of cooler systems is much higher than the working temperature of freezer systems, no icing problems occur due to humidity of the incoming air.
  • One of the advantages is, that the swing doors seal against each other and therefore the mullions can be omitted.
  • a further advantage is, that - since a mullion is not necessary - the angled view or the view directly in front of the freezer device on the products is not blocked and therefore the comfort for customers is increased.
  • An even further advantage is, that a cost-effective implementation can be provided.
  • said at least one sealing is at least translucent, preferably at least partially transparent. This further enhances the view for customers on the products, since the customer's view is not blocked by a non-transparent sealing. A further advantage is that an overall appealing impression for customers is provided.
  • each of said at least two adjacent swing doors comprises a sealing for providing said sealing function. This enhances the sealing function and thus energy is saved when using the swing doors in a cooler or freezer device.
  • said two adjacent sealings have the same shape.
  • the term "same shape” is to be understood in the most general sense or meaning and shall in particular include all shapes which can be transferred into one another, e.g. by rotation or mirroring. This enables manufacturing of the swing door system in a cost-effective way.
  • one of said two adjacent sealings is adapted to provide at least partially a form-locking connection. This enables providing for instance a stop by one of the swing doors for the adjacent swing door. Thus, mechanical stability in a closed position as well as an enhanced sealing in a closed position of the swing doors is provided.
  • said at least one sealing has at least partially circular shape. This enhances the flexibility in terms of arranging adjacent doors respectively their opening direction: due to the circular shape of the sealing a swing door can either open in the same or in an opposite opening angle with regard to the adjacent swing door.
  • said form-locking connection is provided by a partial convex form of one of said sealings and a corresponding concave form of said other one of said sealings. This enables in a simple way to provide a partial form-locking connection.
  • the sealing surface provided by said at least one sealing is inclined with an angle to the opening direction of the swing doors from said closed position said angle being smaller than 90°, preferably smaller than 60°, in particular smaller than 30°, preferably 0°. This enables to provide a larger sealing surface thus enhancing the sealing function. Further advantages are that a sufficient sealing function and an easy opening of the swing doors and a larger transparent product display area is provided.
  • said at least one sealing has an essentially triangular shape. This enables a reliable attachment to the swing door with two surfaces of the triangular shape wherein the non-attached third surface provides the sealing surface.
  • the term "essentially triangular” shall include in particular triangular, triangular with rounded corners, multiple edge corners or the like.
  • said two adjacent swing doors are arranged such that a partial overlap, preferably in a formed common plane, in said closed position of said two adjacent swing doors is provided based on the view parallel to the opening direction.
  • a partial overlap enables a further enhancement of the sealing function between the two adjacent swing doors.
  • At least one of said two adjacent swing doors comprise an angled S-shaped profile at least on a surface of said swing door directed to the other adjacent swing door. This enables in a simple way a partial overlap of two adjacent swing doors while providing enhanced protection of the corresponding surfaces by the profile.
  • a smooth S-shaped profile, a quarter circular profile, or the like can be used.
  • said angle S-shaped profile is at least translucent, preferably at least partially transparent. This further enhances the angled view of customers on products behind the swing doors since there is no blocking of the view by non-transparent profiles.
  • said partial overlap is provided by an extending pane of one swing door in the direction to the other adjacent swing door and vice versa. This provides in a simple way a partial overlap and enables an enhanced sealing function.
  • one of said two adjacent swing doors is formed such to provide a stop for the other adjacent swing door. This enhances the handling of the swing doors for customers on the one hand and on the other hand a reliable closure as well as an enhanced sealing function is enabled.
  • At least one of said two swing doors comprises a gas-filled insulating glass unit or a vacuum glass unit, said gas-filled insulating glass unit or said vacuum glass unit comprises at least two glass panes being spaced apart from each other by one or more spacer elements.
  • Said gas-filled insulating unit may comprise air and/or a one or more noble gases.
  • said spacer elements are at least translucent, preferably at partially transparent. This further enhances the angled view of customers on products behind the swing doors since there is no blocking of the view by non-transparent spacers.

  • said swing doors with the rotating axis in the center of said swing door have a sealing, said sealing having essentially semicircular shape. This provides an easy opening of said swing door without interfering with the adjacent swing door.
  • At least one of the swing doors comprises hinges at opposite ends of said at least one swing door for providing opening and closing by rotation about a rotating axis. This enhances the flexibility when attaching the swing doors for instance into a cabinet or the like.
  • a thickness of a swing door with at least one sealing is equal to or smaller than 40 mm, preferably equal to or smaller than 30 mm, in particular equal to or smaller than 26 mm, wherein said thickness being measured in a handle-free region parallel to the opening direction in a closed position of said swing door and/or wherein a width of a region in a closed position of said swing door comprising at least one sealing, a center of said rotating axis of at least one of said swing doors, preferably further comprising at least one profile and spacer elements for spacing apart panes of a swing door, wherein said width being measured perpendicular to the opening direction in a closed position of said swing door and parallel to the plane of said panes of said swing door, is equal to or smaller than 50 mm, preferably equal to or smaller than 41 mm, in particular equal to or smaller than 34 mm.

  • a transparent pane of at least one of said adjacent swing doors comprises a gasfilled insulating glass unit (IG) or a vacuum insulated glass unit (VIG).
  • IG gasfilled insulating glass unit
  • VIG vacuum insulated glass unit
  • the gasfilled insulating glass unit and/or the vacuum insulated glass unit comprise at least two glass panes, often three glass panes, being spaced apart from each other by one or more spacers or spacer elements.
  • the glass panes may comprise a thickness of 3 mm to 5 mm, often 4 mm and/or may comprise an antifog-coating or an antifog foil and/or a heatable coating and/or a low-emissivity coating and/or an anti-reflective coating.
