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. A temperature-controlled display cabinet that is a freezer island for a grocery store including a frame structure surrounding at least one openable product space for food products, the temperature-controlled display cabinet that is the freezer island comprising:

at least one gravitationally closable door that is in an inclined position in relation to a vertical direction such that, from the view of the customer side of the cabinet, the main direction of the main surface of the door is backwards and upwards inclined, the door being formed as a door arrangement comprising

the door,

hinges configured to turnably attach the door to the frame structure, and

an opening and closing mechanism, which is formed of a spring mechanism configured to assist opening the door by lightening the load caused by the door and a hydraulic system configured to slow down a closing speed of the door during closing movement thereof.

2. The temperature-controlled display cabinet according to claim 1, wherein the door comprises a transparent main surface and a door frame around the main surface.

3. The temperature-controlled display cabinet according to claim 2, wherein the door is inclined such that the horizontal component of the inclination angle is smaller than the vertical component of the inclination angle.

4. The temperature-controlled display cabinet according to claim 1, wherein the door is inclined such that the horizontal component of the inclination angle is smaller than the vertical component of the inclination angle.

5. The temperature-controlled display cabinet according to claim 1, wherein the door is inclined in an inclination angle of at least 15°

and less than 25°

in relation to the vertical direction.

6. The temperature-controlled display cabinet according to claim 5, wherein the door is inclined in an inclination angle of 18-23°

in relation to the vertical direction.

7. The temperature-controlled display cabinet according to claim 1, wherein the product space of the temperature controlled display cabinet comprises a shelf part comprising shelves and a chest part below the shelf part.

8. The temperature-controlled display cabinet according to claim 7, wherein one shelf of the shelf part is visible in the horizontal direction through the door.

9. The temperature-controlled display cabinet according to claim 8, wherein the product space of the temperature controlled display cabinet comprising the shelf part and the chest part forms a continuous space.

10. The temperature-controlled display cabinet according to claim 7, wherein the product space of the temperature controlled display cabinet comprising the shelf part and the chest part forms a continuous space.

11. The temperature-controlled display cabinet according to claim 1, wherein the temperature-controlled display cabinet is a semi-vertical display cabinet.

12. The temperature-controlled display cabinet according to claim 1, wherein the opening and closing mechanism further comprises a turning arm mechanism.

13. The temperature-controlled display cabinet according to claim 12, wherein the turning arm mechanism comprises at least one telescopic arm that is arcuate.

14. The temperature-controlled display cabinet according to claim 13, wherein the opening and closing mechanism is attached to a frame part of the door and is attached to the door such that when the door is in a closed position, the opening and closing mechanism is located inside the temperature-controlled display cabinet.

15. The temperature-controlled display cabinet according to claim 12, the opening and closing mechanism is attached to a frame part of the door and is attached to the door such that when the door is in a closed position, the opening and closing mechanism is located inside the temperature-controlled display cabinet.

16. The temperature-controlled display cabinet according to claim 15, wherein the opening and closing mechanism is located on the upper part of the door such that the spring mechanism and the hydraulic system are attached to an upper horizontal frame part of the door frame and correspondingly the turning arm mechanism is attached to the upper horizontal part of the door.

17. The temperature-controlled display cabinet according to claim 16, wherein the horizontal upper door frame is provided with an opening through which the turning arm mechanism extends from the door to be connected inside the temperature-controlled display cabinet on the door frame inside-located spring mechanism and the hydraulic system in order to connect the function of the spring mechanism and the hydraulic system to the opening/closing movement of the door.

18. The temperature-controlled display cabinet according to claim 15, wherein the horizontal upper door frame is provided with an opening through which the turning arm mechanism extends from the door to be connected inside the temperature-controlled display cabinet on the door frame inside located spring mechanism and the hydraulic system in order to connect the function of the spring mechanism and the hydraulic system to the opening/closing movement of the door.

19. The temperature-controlled display cabinet according to claim 1, characterized wherein the hydraulic system and the spring mechanism are located sequentially.

20. The temperature-controlled display cabinet according to claim 1, wherein the hydraulic system and the spring mechanism are located at least partially lengthwise within each other.
