(12) The present invention is defined by the appended independent claim, and is in the following description and figures illustrated and described with reference to a latching hinge 1 according to an embodiment of the invention.

(13) The latching hinge 1 according to an embodiment of the invention is illustrated in FIG. 1. The latching hinge is shown in latched position with the handle 2 rotated into contact with the body 3. A locking element 21 may be rotated to lock the handle 2 in latched position. In latched position, the latching hinge 1 has the function of a hinge, wherein the body 3 and handle 2 are rotatable relative to the hinge part 4.

(14) In FIG. 2, the latching hinge 1 is show in unlatched position with the handle 2 rotated away from the body 3, allowing the body 3 to be released from the hinge part 4. In the unlatched position of the handle 2, the latching hinge 1 is openable as a latch for the door to a door frame.

(15) FIG. 3 shows a door facing side of the latching hinge 1. A support plate 6 is attached to the body 3 through holes 61 via fastening means such as screws. The body 3 and support plate 6 are configured to abut a door. The hinge 4 is configured to be arranged to a door frame.

(16) An example of a body facing side of a distance element 5 according to the invention is shown in FIG. 4a. The distance element 5 is arranged between the body 3 and the support plate 6. The distance element 5 comprises at least one hole 51 for fastening the distance element 5 to the support plate 6 and the body 3. Fastening may be done by for example use of a screw or other fastening means.

(17) The thickness t varies across the distance element 5, with a first portion p1 having a thickness t1 which may be less than a thickness t2 of a second portion p2. The thickness t2 is further smaller than a thickness t3 of a third portion p3 of the distance element 5.

(18) The distance element 5 further comprises a setting screw head 52 for moving the distance element 5 between different positions of the distance element. The setting screw head 52 may be a socket head cap screw, a screw head, a nut, or other means for rotation. The setting screw head 52 protrudes through the body 3 such that the distance element 5 can be moved or rotated without exposing the body facing side of the distance element 5, as illustrated in FIG. 2. The distance may be elected using marks 33 on the body, indicating the position or thickness of the current position of the distance element, also indicated in FIG. 2.

(19) The different thicknesses t1, t2, t3 set the distance between the support plate 6 and the body 3. The distance element 5 may be moved between the positions by rotation or by a linear motion. The distance element is in the illustrated embodiment moved by rotation around the setting screw head 52. The position of the distance element may alternatively be shifted by for example linear vertical or horizontal movement of the distance element.

(20) The distance element 5 may further be of a circular or circle sectional shape or of any other shape, such as a rectangular shape comprising different thicknesses in different portions of the element.

(21) In FIG. 4b the support plate facing side of the distance element 5 is shown. The distance element 5 comprises portions p1, p2, p3 of different thicknesses t1, t2, t3, and is moveable between different positions when arranged in the latching hinge 1. Between each portion p1, p2, p3 and an adjacent portion p1, p2, p3 there is a side edge 50, 50′. The side edges 50, 50′ provide the change of thickness between the portions p1, p2, p3. The side edges 50, 50′ are inclined towards the connecting portions p1, p2, p3. The distance element 5 further comprises a protrusion 53. The protruding surface 53 is at least partly circularly shaped, and has a curvature C.sub.D facing the portions p1, p2, p3. The protrusion 53 extends to have a thickness larger than the thickness t3 of the third portion p3.

(22) FIG. 5a shows the distance element 5 in a first position where the first portion p1 with thickness t1 is fixed by screws 32 via the holes 51 to the body 1 and sets the distance between the body 1 and the support plate 6 (not shown). FIG. 5a further illustrates the protruding parts 31, which may serve as to maximize the contact area between the support plate 6 and the body 3. The support plate 6 and the body 3 may be fixed to each other by screws 32. The means 32 fastening the body 3 and the support plate 6 to each other may extend through a protruding part 31.

(23) The protruding part 31 has a longitudinal extension and is positioned either on the support plate 6 or as illustrated on the body 3. The protruding part 31 has a circle segment profile to maximize the contact area as the support plate 6 and body 3 are rotated away from each other. The distance element 5 is positioned in a cavity 34 of the body 3 such that when the distance element 5 is positioned in a position with the thinnest portion p1 in contact with the support plate 6, the support plate 6 is in contact with the body 3 at the area next of the distance element. In such situation, the distance element 5 has no effect on the positioning of the support plate 6 relative to the body 3.

(24) FIG. 5b shows the distance element 5 in a third position where the third portion p3 sets the distance between the body 3 and the support plate 6 to a different distance than that of p1, illustrated in FIG. 5a. The distance element 5 is fixed in said third position by screw 32 via the holes 51 to the body 1. In the same manner, in a second position, not shown, a second portion p2 having a thickness t2 sets the distance between the body 1 and the support plate 6.

(25) The support plate 6 is illustrated in FIG. 6. The support plate 6 comprises a contacting part 62 which abuts the distance element 5 as to create an area of contact there between regardless the current position of the distance element 5. The contact part 62 is in contact with the portion p1, p2, p3 that currently is in a distance setting position (as p1 in FIG. 5a). The portions p1, p2, p3 of the distance element 5 are divided as segments of the distance element 5. At least one of the sides 50, 50′ of each portion p1, p2, p3 extends in a corresponding angle as the sides 60, 60′ of the contacting part 62. The sides 50,50′ of the distance element 5 and the angle corresponding sides 60, 60′ of the contacting part 62 aid in holding the distance element 5 in a fixed position relative the support plate 6 in certain of the distance element's 5 positions p1, p2, p3 when the sides of the different parts are in contact with each other.

(26) The distance element 5 has a protrusion 53 (see FIG. 4b) extending above the portions p1, p2, p3 and facing the support plate 6. The protrusion 53 has a curvature C.sub.D corresponding to the curvature C.sub.S of the contacting part such that the side of the protrusion 53 of the distance element and the side 63 of the contacting part provide an area of contact between the support plate and the distance element 5. This area of contact aids in guiding the distance element 5 in the correct position with respect to the support element 6 during rotation of the distance element 5.

(27) Further, the support plate 6 comprises holes 61 screws 32 to attach to the body 3 and a hole 61′ for fixation to the body 3 via the distance element 5. The support plate 6 comprises a first area 6a and a second area 6b. The first area 6a may be in contact with the body 3 for a certain thickness of the distance element 5 and tilted away from the body 3 when the thickness t of the distance element 5 increases. The second area 6b of the support plate 6 is always in contact with the body 3.

(28) A cross-section of the latching hinge 1 is illustrated in FIG. 7. The body 3 comprises a protruding surface 31 such as to create a contact surface to the support plate 6 when the support plate 6 is distanced from the body 3 by the distance element 5 (see FIG. 8b). The protruding surface 31 has a cross-sectional form of a circle segment extending above the surrounding surface of the body 3. When the support plate 6 is distanced from the body 3 at the location of the distance element 5, the support plate 6 will be rotated around a point on the protruding surface 31. A connection between the body 3 and the support plate 5 can thereby be withheld at the same place, i.e. by means of fastening means extending through the protruding surface 31.

(29) In FIG. 8a a cross-section of the body 3, the support plate 6, and the distance element 5 of the latching hinge 1 are shown. The distance element 5 is shown with a portion p1 of thickness t1 setting the distance between the support plate 6 and the body 3. In a certain position a lower surface 6c of the support plate 6 lies in a plane A suspended by a door facing side of the body 3. Using the means 52 for moving the distance element 5 to a position p2, p3 with a thickness t2, t3 thicker than t1, will cause the first area 6a of the support plate to tilt away from the body 3 through the plane A, as illustrated in FIG. 8b, such that the lower surface 6c of the support plate 6 is offset in relation to plane A.

(30) The latching hinge 1 may be produced from plastics, metal, a combination of these of other suitable material and may be produced in separate parts for example by injection molding.

(31) In the drawings and specification, there have been disclosed preferred embodiments and examples of the invention and, although specific terms are employed, they are used in a generic and descriptive sense only and not for the purpose of limitation, the scope of the invention being set forth in the following claims.
