ACCESS DOOR

Abstract

An access door (1) for application in a refrigerated cabinet comprises a multi-walled plastic door construction of a sheet-like first wall (10) and a plane-parallel second wall (20). The walls each comprise all around an edge part (12,22) with which the walls are connected. One of the two walls has a central part (21) which lies offset relative to the edge part (22) and wherein the central part and the edge part are connected by a bridge part (23a,23b). The door construction has a mounting section (25) for mounting an adjusting member thereon in order to enable adjustment of the door construction in the refrigerated cabinet between a position closing the refrigerated cabinet and an open position. The bridge part (23a,23b) comprises a primary bridge part section (23a) which is adjacent to the mounting section (25) and extends at a first angle from the edge part and a secondary bridge part section (23b) which extends at a second angle from the edge part, wherein the second angle is smaller than the first angle.

[0023] FIG. 2B is a detail view of a longitudinal section of the access door shown in FIG. 1B along line B-B;

[0024] FIG. 2C is a detail view of the circled part D of the access door shown in FIG. 1B; and

[0025] FIG. 2D is a detail view of a cross-section of the access door shown in FIG. 1B along line B-B.

[0026] The figures are purely schematic here and not drawn to scale. Some parts and dimensions in particular may be exaggerated to greater or lesser extent for the sake of clarity.

[0027] As shown in FIGS. 1A, 1B, access door (1) according to the present invention comprises a door construction with a sheet-like first wall (10) and an at least substantially plane-parallel second wall (20). Walls (10, 20) are both manufactured here from moulded polymethyl methacrylate so that the resulting door construction has a high transparency. First wall (10) is substantially a wholly flat sheet, while second wall (20) is manufactured from a flat sheet by means of a mould. Second sheet (20) comprises here a base part (21) which lies offset relative to an edge part (22) with which second wall (20) is attached against an edge part (12) of first wall (10) so as to form the multi-walled door construction. The attachment between the edge parts of walls (10, 20) is realized by applying a suitable transparent acrylate adhesive therebetween.

[0028] Base part (21) and edge part (22) of second wall (20) are connected by an at least substantially linear bridge part (23), whereby second wall (20) has a certain shallow tray shape. Such a tray shape imparts stiffness and strength to the door construction so that, when applied in a refrigerated cabinet, it will not deform and also leaves a cavity space (30) relative to the first wall in the door construction for a good insulating action of the access door.

[0029] The access door has two mutually opposite length sides which define a height of the access door, and two mutually opposite width sides which form respectively an upper side and underside of the access door. A rear side of the access door facing toward the product space can comprise the first wall and, in an alternative embodiment, comprise the second wall. Provided on one of the length sides is a grip provision for the access door. In this exemplary embodiment the grip provision comprises two recesses (24) in which a grip member such as a door handle can be arranged and connected to the access door in order to enable easy manual opening and closing of the access door relative to the refrigerated cabinet in which it is applied.

[0030] Close to the opposite length side the access door has on both width sides a mounting section (25) for mounting of an adjusting member such as a hinge. The design of the second sheet is adapted hereto in the sense that the bridge part and base part provide space therefor.

[0031] As shown in more detail in FIGS. 2A to 2D, bridge part (23) in second wall (20) has at least a primary bridge part section (23a) and a secondary bridge part section (23b). The primary bridge part section (23a) is adjacent to mounting sections (25) and extends along the whole width sides of the access door. The secondary bridge part section (23b) extends along the length sides of the access door. The primary bridge part section (23a) extends from edge part (22) at a first angle of between 110 and 165 degrees, while the secondary bridge part section (23b) extends from edge part (22) at a second angle of between 100 and 125 degrees, wherein the second angle is smaller than the first angle. The secondary bridge part section which forms a greatest part of the bridge part on the length sides imparts a good stiffness and strength to the door construction due to the relatively small angle which it describes relative to the edge part. The primary bridge part section adjacent to the mounting section, which in practice can be considerably loaded by an adjusting member provided thereon, has a better resistance to such a load due to the relatively greater angle in relation to the edge part, whereby the access door is less likely to be adversely affected or to break close to the adjusting member.

[0032] Although the invention has been further elucidated on the basis of only a single exemplary embodiment, it will be apparent that the invention is by no means limited thereto. On the contrary many variations and embodiments are still possible within the scope of the invention for a person with ordinary skill in the art.
