Definitions
- the present invention relates to a cooling device wherein the insulation materials such as polyurethane and the like are prevented from jutting out.
- hinge bearings are described that are mounted in cylindrical openings. These hinge bearings are mounted in the openings by means of the included hinge pins thereof, from the exterior towards the interior of the door filled with insulation material.
- the hinge bearings explained in states of the art do not have the sufficient durability in cases wherein polyurethane exerts excessive pressure. In excessively pressurized conditions, the bearing may be displaced and may cause the insulation materials such as polyurethane and the like jut out of the cooling device door.
- the aim of the present invention is the realization of a cooling device comprising a hinge bearing that is resistant to pressures of different intensities exerted during foaming the inside of the door with insulation material.
- the door is secured to the cabinet of the cooling device by a hinge.
- the shaft of the hinge disposed on the cabinet is seated in the housings situated on the door and thus provides the door to move pivotally around the shaft.
- Housings are provided on the door wherein the shaft will be seated.
- a hinge bearing is placed in these housings, having preferably in the form of a cylindrical body with one base being open. The body has a protrusion on its end near the closed base.
- the hinge bearing contrary to state of the art, is fitted to the housing on the door from the side filled with polyurethane, not from the exterior of the door.
- the remaining portion of body is inserted entirely into the housing while the protrusion with a bigger diameter than the housing stays outside the housing and is seated on the inner surface of the door encircling the housing.
- the protrusion prevents the movement of the hinge bearing outwards the door. Since the protrusion has a bigger diameter than the housing, the hinge bearing cannot go through the housing and project out of the door in spite of the pressure exerted by polyurethane and polyurethane does not jut out of the inner volume of the door.
- lugs are provided that lock the hinge bearing to the door.
- the lugs prevent the movement of the hinge bearing towards the inside of the door.
- the lugs have an inclined form that does not prevent the hinge bearing to be seated in the housing, but once seated does not allow detachment from the housing.
- the end of the bearing containing the lugs project out from the housing and are seated on the edges of the housing at the outer side of the door, preventing the bearing to fall inside the door.
- ribs are provided on the lateral surfaces of the body. These ribs prevent the motion of hinge bearing due to motion of door.
- Figure 1 - is the perspective view of the cooling device of the present invention.
- Figure 2 - is the cross- sectional view of the hinge bearing when disposed on the door in the prior art.
- Figure 3 - is the cross- sectional view of the door and the hinge bearing before being disposed on the door in an embodiment of the present invention.
- Figure 4 - is the cross- sectional view of the hinge bearing when disposed on the door in an embodiment of the present invention.
- Figure 5 - is the perspective view of the hinge bearing in an embodiment of the present invention.
- Figure 6 - is the side view of the hinge bearing in an embodiment of the present invention.
- Cooling device 2. Body
- the cooling device (1) of the present invention comprises:
- the hinge bearing (3) is mounted to the housing (8) from the inner side of the door
- the hinge bearing (3) comprises:
- a protrusion (5) arranged on the body (2), being larger than the housing (8) such that it does not fit in the orifice of the housing (8) that opens to the inner side (P) of the door (7) that will be filled with insulation material later on and preventing the housing (8) from projecting out of the door (7) by bearing on the edges thereof at the inner side (P) of the door (7).
- the body (2) is in the form of a cylinder with an open base.
- the lug (4) on the sides of the open base, projects from the lateral sides towards outside of the body (2) ( Figures 4, 5).
- the lug (4) sits on the orifice of the housing (8) opening to the outside the door (7) and prevents the hinge bearing (3) from falling to the interior portion of the door (7) that will be filled with insulation material.
- the protrusion (5) is arranged on the sides of the closed base of the body (2) and large enough not to fit in the housing (8) wherein the hinge bearing (3) will be mounted.
- the hinge bearing (3) comprises at least one rib (6) arranged to make a projection on the lateral side of the cylindrically shaped body (2) ( Figure 6). While the shaft (9) rotates in the hinge bearing (3) the rib (6) provides friction with the walls of the housing (8) and prevents the rotation of bearing (3) inside the housing (8).
- the hinge bearing (3) contrary to state of the art, is fitted to the housing (8) on the door (7) from the side to be filled with polyurethane, not from the exterior of the door (7).
- the lugs (4) are configured to be inclined form providing to be inserted into the housing (8) but not allowing detachment therefrom.
- the hinge bearing (3) is placed in the housing (8), the lugs (4) are seated on the orifice of the housing (8) facing the outside and prevent the bearing (3) from falling inside the door (7) filled with the insulation material.
- the production of the hinge bearing (3) is simple and inexpensive.
- the bearing (3) is ensured not to be detached from place and also the use of additional elements such as styropor, plugs etc. are not required.
