Abstract

A dispenser (1) for hygienic products, has a main portion (2) attachable to a wall. The dispenser includes a door (7) pivotally mounted to a bottom portion (3) of the main portion (2). The door (7) is operable at a top portion (4) of the main portion (2) and swung out from the main portion (2) in a rotational movement upon opening. The door (7) is pivotally mounted to the main portion (2) via a pair of first and second link arms (10) describing a trapezoid arrangement when the door (7) is closed, and the trapezoid arrangement is arranged to balance the rotational movement of the door (7).

Claims

1. A dispenser for hygienic paper products, comprising:

a main portion, a bottom portion, a top portion, two side portions, a back portion and a door, where the back portion is attachable to a wall, the side portions extending essentially perpendicular from the back portion and extend from the bottom portion to the top portion, at least one of said side portions having a stop member;

the door is pivotally mounted to the bottom portion of the main portion, and being openable at the top portion of the main portion and swung out from the main portion in a rotational movement upon opening so that an upper part of the door swings away from the top portion, wherein the door is pivotally mounted to the main portion via at least a pair of first and second link arms;

the first link arm having a reinforcement member, the first link arm being pivotally mounted to one of the side portions at a first point of attachment separate from the reinforcement member and pivotally mounted to a side of the door via a second point of attachment near a bottom part of the door;

the second link arm being pivotally mounted to the side portion at a third point of attachment and is pivotally mounted to the side of the door via a fourth point of attachment near the bottom part of the door;

wherein, in a closed door position, the first and second link arms together with an imaginary line between the first and third points of attachment and an imaginary line between the second and fourth point of attachment describe a trapezoid arrangement arranged to balance the rotational movement of the door upon opening due to the first link arm being arranged to give the second point of attachment a movement along a rotational path of the first link arm about the first point of attachment;

the second link arm being arranged to give the fourth point of attachment a movement along a rotational path of the second link arm about the third point of attachment, the first link arm and the second link arm having different centres of rotation; and

the reinforcing member is configured to reinforce the second link arm over the stop member in an intermediate semi-closed position.

2. The dispenser according to claim 1, wherein the door is pivotally mounted to the main portion via at least a pair of first and second link arms.

3. The dispenser according to claim 2, wherein the first link arms are pivotally mounted to each side of the main portion at the first points of attachment and are pivotally mounted to each side of the door via second points of attachment, and the second link arms are pivotally mounted to each side of the main portion at the third points of attachment and are pivotally mounted to each side of the door via the fourth points of attachment.

4. The dispenser according to claim 3, wherein the first point of attachment is placed above and closer to the door than the third point of attachment and where the fourth point of attachment is placed below and closer to the main portion than the second point of attachment.

5. The dispenser according to claim 1, wherein the side portions have a contour that follows a contour of the door such that when the door is closed, the door covers edge portions of the side portions facing the door.

6. The dispenser according to claim 1, wherein the upper part of the door is bent towards the main portion at an angle to a main part of the door.

7. The dispenser according to claim 1, wherein first and second link arms are arranged such that the rotational movement of the door is transformed also into a translational movement of the bottom part of the door in both a horizontal direction and in a vertical direction.

8. The dispenser according to claim 7, wherein the translational movement is a consequence of that the first link arm being arranged to give the second point of attachment a movement along the rotational path of the first link arm, and where the second link arm is arranged to give the fourth point of attachment a movement along the rotational path of the second link arm;

and the first link arm and the second link arm having different centres of rotation.

9. The dispenser according to claim 2 wherein the side portions have a contour that follows a contour of the door such that when the door is closed, the door covers edge portions of the side portions facing the door.

10. The dispenser according to claim 3, wherein the side portions have a contour that follows a contour of the door such that when the door is closed, the door covers edge portions of the side portions facing the door.

11. The dispenser according to claim 4, wherein the side portions have a contour that follows a contour of the door such that when the door is closed, the door covers edge portions of the side portions facing the door.

12. The dispenser according to claim 2, wherein the upper part of the door is bent towards the main portion at an angle to a main part of the door.

13. The dispenser according to claim 3, wherein the upper part of the door is bent towards the main portion at an angle to a main part of the door.

14. The dispenser according to claim 4, wherein the upper part of the door is bent towards the main portion at an angle to a main part of the door.

15. The dispenser according to claim 2, wherein first and second link arms are arranged such that the rotational movement of the door is transformed also into a translational movement of the bottom part of the door in both a horizontal direction and in a vertical direction.

16. The dispenser according to claim 3, wherein first and second link arms are arranged such that the rotational movement of the door is transformed also into a translational movement of the bottom part of the door in both a horizontal direction and in a vertical direction.

17. The dispenser according to claim 4, wherein first and second link arms are arranged such that the rotational movement of the door is transformed also into a translational movement of the bottom part of the door in both a horizontal direction and in a vertical direction.

18. The dispenser according to claim 5, wherein first and second link arms are arranged such that the rotational movement of the door is transformed also into a translational movement of the bottom part of the door in both a horizontal direction and in a vertical direction.

19. A dispenser for hygienic paper products, comprising:

a main portion;

a bottom portion;

a top portion;

a back portion;

two side portions, at least one of said side portions having a stop member the side portions extending essentially perpendicular from the back portion and extend from the bottom portion to the top portion, at least one of said side portions having a stop member;

a back portion configured to be attachable to a wall;

a door pivotally mounted to the bottom portion and being openable at the top portion and swung out from the main portion in a rotational movement upon opening so that an upper part of the door swings away from the top portion, wherein the door is pivotally mounted to the main portion via at least a pair of first and second link arms;

the first link arm having a reinforcement member, the first link arm being pivotally mounted to one of the side portions at a first point of attachment separate from the reinforcement member and pivotally mounted to a side of the door via a second point of attachment near a bottom part of the door; and

the second link arm being pivotally mounted to the side portion at a third point of attachment and is pivotally mounted to the side of the door via a fourth point of attachment near the bottom part of the door;

wherein in a closed door position, the first and second link arms together balance the rotational movement of the door upon opening due to the first link arm being arranged to give the second point of attachment a movement along a rotational path of the first link arm about the first point of attachment,

the first link arm and the second link arm having different centres of rotation, and

the reinforcing member is configured to reinforce the second link arm over the stop member in an intermediate semi-closed position.
