An effortless sliding action with a simultaneously reliable seal is achieved by the front frame having a bearing surface that is oriented horizontally relative to a vertical direction of gravity. ## Claims ### Claim 1 A cooling appliance (1), comprising: a housing (6) including at least one refrigeration compartment that is accessible from above, the housing (6) including a cover frame (5) with a front frame part (50), the front frame part (50) including a support section (512) oriented horizontally relative to a vertical direction of gravity, and a front guide section (511) having a vertical inner surface extending vertical from the support section (512); at least one laterally movable sliding lid (2) extending over the at least one refrigeration compartment, the sliding lid having a transparent window (20) which has a heat-reflecting inner coating (21) and at least in a front longitudinal region via an outwardly convex curvature perpendicular to a longitudinal direction comes to an end in a longitudinal edge that has a front frame (30) adjacent the front frame part (50) of the housing (6), the front frame (30) having a bearing surface (312) oriented horizontally relative to the vertical direction of gravity, wherein the bearing surface (312) has a sealing element in contact with the horizontal support section (512); and spacer elements (314) that protrude beyond a frontal plane of the front frame (30) that is perpendicular to the bearing surface (312), wherein the spacer elements are spaced apart from the vertical inner surface of the front guide section (511), wherein the spacer elements (314) are formed convex outward toward the vertical inner surface of the front guide section (511) so that the spacer elements (314) provide a point-by-point support opposite to the vertical inner surface of the front guide section (511); wherein the sealing element forms a sealed sliding surface upon which the front frame (30) travels along the first surface of the front frame part (50) upon movement of the sliding lid (2), and wherein the spacer elements prevent the sliding lid (2) from wedging in the cover frame (5) as the sliding lid (2) is moved. ### Claim 2 (depends on 1) The cooling appliance according to claim 1, wherein a front cross-sectionally vertical edge of the front frame (30) serves as a supporting section (313) for a longitudinal guidance and has the spacer elements (314) that protrude beyond the frontal plane. ### Claim 3 (depends on 2) The cooling appliance according to claim 2, wherein the front frame is in a form of a longitudinal profile with a connecting section (300) that embraces an inner surface region and an outer surface region of the transparent window at a front longitudinal edge and has a bearing section (310) that is formed onto and oriented at an angle to it, which has the bearing surface (312). ### Claim 4 (depends on 3) The cooling appliance according to claim 3, wherein an underside of the sealing element has good sliding properties and is a separate sealing element (7) that is mounted on the bearing surface (312). ### Claim 5 (depends on 4) The cooling appliance according to claim 4, wherein the bearing section (310) has a longitudinally extending receiving chamber (311) bounded on an underside by an end wall with the bearing surface (312) and into which a holding section of the sealing element (7) is inserted. ### Claim 6 (depends on 5) The cooling appliance according to claim 5, wherein the spacer elements (314) have externally arched support surfaces. ### Claim 7 (depends on 6) The cooling appliance according to claim 6, wherein a rear longitudinal edge of the transparent window (20) has a rear frame (35) that has a bearing section (350) with a horizontal bearing surface on an underside. ### Claim 8 (depends on 7) The cooling appliance according to claim 7, wherein the transparent window (20) rises from the front longitudinal edge via the convex curvature and transitions into a flat, horizontal region that adjoins at a rear with the rear longitudinal edge having the rear frame (35) that has the horizontal bearing surface. ### Claim 9 (depends on 8) The cooling appliance according to claim 8, wherein an upper edge region of the housing (6) has the cover frame (5) that has at least one longitudinally extending support surface (510) which is matched to a position and a size of the bearing surface (312), and has the guide section (511) which is matched to a second position and a second size of the supporting section (313). ### Claim 10 (depends on 2) The cooling appliance according to claim 2, wherein the spacer elements (314) have externally arched support surfaces. ### Claim 11 (depends on 1) The cooling appliance according to claim 1, wherein the front frame is in a form of a longitudinal profile with a connecting section (300) that embraces an inner surface region and an outer surface region of the transparent window at a front longitudinal edge and has a bearing section (310) that is formed onto and oriented at an angle to it, which has the bearing surface (312). ### Claim 12 (depends on 11) The cooling appliance according to claim 11, wherein the bearing section (310) has a longitudinally extending receiving chamber (311) bounded on an underside by an end wall with the bearing surface (312) and into which a holding section of the sealing element (7) is inserted. ### Claim 13 (depends on 1) The cooling appliance according to claim 1, wherein an underside of the sealing element has good sliding properties and is a separate sealing element (7) that is mounted on the bearing surface (312). ### Claim 14 (depends on 1) The cooling appliance according to claim 1, wherein a rear longitudinal edge of the transparent window (20) has a rear frame (35) that has a bearing section (350) with a horizontal bearing surface on an underside. ### Claim 15 (depends on 14) The cooling appliance according to claim 14, wherein the transparent window (20) rises from a front longitudinal edge via the convex curvature and transitions into a flat, horizontal region that adjoins at a rear with a rear longitudinal edge of the rear frame (35) that has the horizontal bearing surface. ### Claim 16 (depends on 1) The cooling appliance according to claim 1, wherein an upper edge region of the housing (6) has the cover frame (5) that has at least one longitudinally extending support surface (510) which is matched to a position and a size of the bearing surface (312), and has the guide section (511) which is matched to a second position and a second size of the supporting section (313). ### Claim 17 (depends on 1) The cooling appliance according to claim 1, wherein each of the spacer elements (314) is a rivet that provides a rounded point contact surface facing the vertical inner surface of the front guide section (511).
