Definitions

  • This invention relates to door handles for domestic refrigeration appliances, and in particular to handles that reduce the force, exerted by the user, that is necessary to open the door of the domestic refrigeration appliance.
  • DE202005008449U thus discloses a domestic refrigeration appliance that comprises two door handles.
  • the refrigeration appliance comprises two bodies and two doors, the doors being connected with freedom of rotation to said bodies.
  • Each handle, each one disposed on a door comprises a tilting actuator, with the result that when the user rotates the handle said actuator presses against the front part of the corresponding body, helping the door to separate from the body.
  • the actuator which is L-shaped, comprises a gripping arm so that the user may operate said actuator.
  • the handle of the invention is suitable for use in a domestic refrigeration appliance that comprises:
  • Said handle also comprises:
  • the actuator presses against the front part of the main body when it rotates in either of the two directions.
  • the actuator rotates in relation to a first axis of rotation when it rotates according to one of the two directions and rotates in relation to a second axis of rotation when it rotates according to the other direction.
  • the door handle of the invention enables the door of the domestic refrigeration appliance to be opened with a reduction in the force exerted by the user, and also enables the door to be opened by rotating the handle in either of the two directions.
  • FIGS 3A and 3B show a domestic refrigeration appliance 2 that includes at least one handle 1 according to the characteristics of the invention and which comprises:
  • the actuator 5 presses against the front part 3a of the main body 3 when it rotates in either of the two directions.
  • the actuator 5 rotates in relation to a first axis of rotation 7 when it rotates according to one of the two directions and rotates in relation to a second axis of rotation 8 when it rotates according to the other direction.
  • the handle 1 enables the door 4 of the domestic refrigeration appliance 2 to be opened with a reduction in the force exerted by the user and also enables the door 4 to be opened by rotating the handle 1 in either of the two directions.
  • the handle of the invention also comprises at least one support, which is fixed to the door 4, more specifically to the opposite side of the axis of rotation of the door 4, as shown in Figures 3A and 3B , by means of fastening means.
  • the actuator 5 rotates in relation to said support, which comprises a plurality of elements.
  • first axis of rotation 7 is placed in a first elongated housing 9 and the second axis of rotation 8 is placed in a second elongated housing 10, as shown in Figure 6 .
  • Each axis of rotation is associated to a respective rotating pin where a first rotating pin 11 is housed in said first elongated housing 9 and a second rotating pin 12 is housed in said second elongated housing 10. Both the first rotating pin 11 and the second rotating pin 12 are fixed in the support described in the preceding paragraph. In the rest position of the handle 1 both the first rotating pin 11 and the second rotating pin 12 are disposed on the end closest to the stop member 18 of the corresponding elongated housings 9 and 10.
  • This embodiment is particularly advantageous due to the fact that it enables the pusher surface 21 furthest from the rotating pin 11,12 that does not have relative movement in relation to the actuator 5 to have sufficient movement to enable said pusher surface 21 to press against the corresponding support surface 22 of the front face 3a of the main body 3, while the pusher surface 21 closest to the rotating pin 11,12 that does not have relative movement in relation to the actuator 5 has a minimal movement, thereby preventing it from colliding with the door 4 and thus locking the handle 1 without the door 4 being opened.
  • the actuator 5 of the handle 1 comprises a stop member 18 that, when said actuator 5 rotates, presses against a support surface 22 of the front part 3a of the main body 3, helping the door 4 to separate from the front part 3a and thereby reducing the opening force exerted by the user.
  • said stop member 18 is L-shaped, as shown in Figure 7 . This results in a larger pusher surface 21 of the stop member 18, which interacts with the support surface 21 of the front part 3a, without there being any need to alter the width of the door 4 in order to fit a wider actuator 5. Any other shape of the stop member 18 is possible.
  • the actuator 5 is made of metal, preferably steel, and the stop member 18 and actuator 5 may optionally be manufactured as a single piece.
  • the stop member 18 is preferably made of plastic so as not to damage the main body 3.
  • a metal stop member made of steel for example, may also be reinforced with an elastic material, rubber for example.
  • the handle 1 comprises a locking pin 19 housed in a third elongated housing 20 that restricts the rotation of the actuator 5.
  • said third elongated housing is situated in a manner substantially perpendicular to the elongated housings 9 and 10 corresponding to each axis of rotation 7 and 8.
  • the first elongated housing 9, the second elongated housing 10 and the third elongated housing 20 are disposed in such a way that they form a triangle, and where the third elongated housing 20 is vertically equidistant to the other two elongated housings 9 and 10.
  • the actuator 5 comprises an upper and lower surrounding surface 15 on the side closest to the front face 3a of the main body 3.
  • This surrounding surface 15 moves between two guides 16 and 17.
  • Each guide comprises a cylindrical protuberance, not shown in the Figures, in contact with the surrounding surface 15.
  • the profile of the surrounding surface 15 is such that as it is in contact with the protuberances of the guides 16 and 17, it causes the handle 1 of the invention to move in a smooth and guided manner, enabling the required rotation of the handle 1 and preventing the actuator 5 of the handle 1 from moving off-centre.
  • Other shapes of surrounding surface are possible.
  • the handle 1 of the invention also comprises elastic means that, in the rest position of the handle 1, are expanded and thus guarantee that the rotating pins 11 and 12 remain disposed in the end closest to the stop member 18 of the corresponding elongated housings 9 and 10.
  • said elastic means correspond to a first spring 13, linked to the first axis of rotation 7, and to a second spring 14, linked to the second axis of rotation 8.
  • Said elastic means enable the handle 1 to return to its original position once the user stops acting on the handle 1.
  • the first spring 13 returns to its rest position and may even be compressed, and the second spring 14 expands, as shown in Figure 5 .
  • the handle 1 To improve the operating of the handle 1, it comprises two gripping arms 6, one upper and the other lower, connected to the actuator 5 as shown in Figures 1 and 2 , and to improve the feel of said gripping arms 6 these are lined or protected by coverings that may vary in shape and texture. In the preferred embodiment a covering is used that covers both the upper arm 6 and the lower arm 6.
  • the handle 1 of the invention adapts perfectly to the specific characteristics of each user.
  • the handle 1 is suitable for tall and short users and users of medium height as it comprises two gripping arms 6, each one of which is disposed at different heights. It is also adapted to users accustomed to pulling the handle and to those users accustomed to pushing the handle.
