Abstract

A temperature controlled display cabinet (20), in particular a freezer island, for a grocery store includes a frame structure (30) surrounding at least one openable product space (23) for food products, at least one gravitationally closable door (26) that is in inclined position in relation to vertical direction such that from the view of the customer side the main direction of the main surface of the door (26) is backwards and upwards inclined. The door (26) is formed as a door arrangement including the door (26) and an opening and closing mechanism (40).

Claims

1. Temperature controlled display cabinet, in particular a freezer island, for a grocery store comprising a frame structure (30) surrounding at least one openable product space (23) for food products, which temperature controlled display cabinet (20), in particular a freezer island, comprises at least one gravitationally closable door (26) that is in inclined position in relation to vertical direction such that from the view of the customer side the main direction of the main surface of the door (26) is backwards and upwards inclined and which door (26) is formed as a door arrangement comprising the door (26), hinges (29) for turnably attaching the door (26) to frame structure (30), characterized in that the door arrangement further comprises an opening and closing mechanism (40), which is formed of a spring mechanism (41) for assisting opening the door (26) by lightening the load caused by the door (26) and hydraulic means (42) for slowing down closing speed of the door (26) during its closing movement.

2. Temperature controlled display cabinet according to claim 1, characterized in that door (26) comprises a transparent main surface (46) and door frame (47) around the main surface (46).

3. Temperature controlled display cabinet according to claim 1, characterized in that the door (26) is inclined such that the horizontal component of the inclination angle is smaller than the vertical component of the inclination angle.

4. Temperature controlled display cabinet according to claim 1, characterized in that the door is inclined in inclination angle at least 15°

and less than 25°

, advantageously 18-23°

in relation to vertical direction.

5. Temperature controlled display cabinet according to claim 1, characterized in that the product space (23) of the temperature controlled display cabinet, in particular of a freezer island (20) comprises a shelf part (21) comprising shelves (27) and a chest part (22) below the shelf part (21).

6. Temperature controlled display cabinet according to claim 5, characterized in that one shelf (27) the shelf part (21) is visible in the horizontal direction through the door (26).

7. Temperature controlled display cabinet according to claim 5, characterized in that the product space (23) of the temperature controlled display cabinet (20), in particular of a freezer island (20) comprising the shelf part (21) and the chest part (22), forms a continuous space.

8. Temperature controlled display cabinet according to claim 1, characterized in that the temperature controlled display cabinet is a semi-vertical display cabinet.

9. Temperature controlled display cabinet according to claim 1, characterized in that the opening and closing mechanism (40) further comprises a turning arm mechanism (43).

10. Temperature controlled display cabinet according to claim 9 characterized in that the turning arm mechanism (43) comprises at least one telescopic arm (63, 64) and that the at least one telescopic arm (63, 64) is arcuate.

11. Temperature controlled display cabinet according to claim 9, characterized in that the opening and closing mechanism (40) is on one hand attached to a frame part (47) of the door (26) and on the other hand attached to the door (26) such that when the door is in closed position the opening and closing mechanism (40) is located inside the temperature controlled display cabinet (20).

12. Temperature controlled display cabinet according to claim 11, characterized in that the opening and closing mechanism (40) is located on the upper part of the door (26) such that the spring mechanism (41) and the hydraulic means (42) are attached to an upper horizontal frame part of the door frame (47) and correspondingly the turning arm mechanism (43) is attached to the upper horizontal part of the door (26).

13. Temperature controlled display cabinet according to claim 11, characterized in that the horizontal upper door frame is provided with an opening through which the turning arm mechanism (43) extends from the door (26) to be connected inside the temperature controlled display cabinet (40) to the on the door frame (47) inside located spring mechanism (41) and the hydraulic means (42) in order to connect the function of the spring mechanism and the hydraulic means to the opening/closing movement of the door.

14. Temperature controlled display cabinet according to claim 1, characterized in that the hydraulic means (42) and the spring mechanism (41) are located sequentially.

15. Temperature controlled display cabinet according to claim 1, characterized in that the hydraulic means (42) and the spring mechanism (41) are located at least partially lengthwise within each other.

16. Temperature controlled display cabinet according to claim 2, characterized in that the door (26) is inclined such that the horizontal component of the inclination angle is smaller than the vertical component of the inclination angle.

17. Temperature controlled display cabinet according to claim 6, characterized in that the product space (23) of the temperature controlled display cabinet (20), in particular of a freezer island (20) comprising the shelf part (21) and the chest part (22), forms a continuous space.

18. Temperature controlled display cabinet according to claim 10, characterized in that the opening and closing mechanism (40) is on one hand attached to a frame part (47) of the door (26) and on the other hand attached to the door (26) such that when the door is in closed position the opening and closing mechanism (40) is located inside the temperature controlled display cabinet (20).

19. Temperature controlled display cabinet according to claim 12, characterized in that the horizontal upper door frame is provided with an opening through which the turning arm mechanism (43) extends from the door (26) to be connected inside the temperature controlled display cabinet (40) to the on the door frame (47) inside located spring mechanism (41) and the hydraulic means (42) in order to connect the function of the spring mechanism and the hydraulic means to the opening/closing movement of the door.
