- ABSTRACT A three section gravity sliding door system comprising [52] U s 49/231 49/228 49/404 three inclined upper tracks arranged to hang the doors 1 49/309 in two vertical planes, two juxtaposed bottom grooves [51] Int Cl Eosd 15/06 aligned in the vertical planes and three doors arranged [58] Fieid 228 229 in sliding engagement between the respective upper 6 tracks and bottom grooves.
- the present invention relates generally to door closing devices, and more particularly, is directed to auto matic door closers of the inclined track type.
- the present invention is particularly applicable to cabinet constructions such as commercial refrigerators and freezers.
- the employment of three horizontally justaposed doors is useful in facilitating access to the interior of wide refrigerated boxes by arranging the plurality of doors to be self-closirig.
- Prior workers in the field have long developed self-closing door hardware which utilizes inclined tracks for door closing purposes.
- US. Pat. NO. 3,318,048 discloses the use of an inclined upper track for automatically closing a door and this general principle isemployed in the present invention.
- prior workers in the field have been unable to develop satisfactory self-closing arrangements for cabinets and refrigerated boxes when the designed width was such that more than two doors were required to gain access to all parts of the interior of the box.
- the present invention relates generally to gravity type, inclined track, sliding doors, and more particularly, is directed to a three section, gravity door system for use in closing a refrigerated cabinet.
- the present invention relates to a plurality of at least three sliding doors which are arranged in horizontally juxtaposed relation to enclose the front of a cabinet, such as a refrigerated display case.
- a plurality of three inclined upper tracks are employed in side by side relation, one of which supports each of the three sliding doors.
- a pair of bottom positioned grooves align beneath the inclined tracks and retain bottom guides which are affixed to the bottom of the doors therein in all relative positions between open and closed of each simply sliding one door relative to the other doors.
- the inclined tracks serve to automatically and effortlessly close a door after it has been opened for cabinet access.
- the arrangement of the plurality of horizontally sliding doors of the gravity action type eliminates the need for extensive frame systems, pivoting connections, closure hardware and other more or less complicated constructions.
- the present construction greatly simplifies refrigerated display case access and due to the elimination additional frame requirements, the present arrangement of three horizontally sliding doors allows greater access to the cabinet interior contents.
- the geometryof the system is such that the inclined upper tracks are positioned in two horizontally juxtaposed vertical planes to receive the rollers of the individual door hangers of the three doors in rolling engagement thereon.
- the hangers of the respective doors so position relative to the inclined tracks that the right and left doors are aligned in the same first vertical plane.
- the said first vertical plane falls either in front of or behind a second vertical plane in which the middle door positions.
- FIG. 1 is a front elevational view Of a refrigerated display case which is closed by a three section gravity clos-- ing door system in accordance with'the present inven-'
- FIG. 2 is a cross sectional view taken along Line 22 of FIG. 1, looking in the direction of the arrows.
- FIG. 3 is an enlarged cross sectional view taken along Line 3-3 of FIG. 1, looking in the direction of the ar:
- FIG. 1 a three section gravity door assembly generally designated which comprises three doors 12, 14, 16 in horizontal, sliding arrangement to close the front opening 13 of a refrigerated cabinet 18.
- the front opening 13 is defined between a right jamb member 15, a left jamb member 17, a head 19 and a sill 21.
- the doors are provided and arranged to close the front of a cabinet such as a refrigerated cabinet and are horizontally sliding to permit easy access into all interior spaces of the cabinet 18.
- Each door 12, 14, 16 is of the gravity closing type and is suspended from a individual, inclined, respective track 20, 22, 24 as hereinafter-more fully set forth.
- the center door 14 ately behind the center door 14.
- the incline of the respective upper tracks 20, 24 causes the doors 12, 16 to automatically close in conventional manner upon removal of the forces which urge the doors upwardly along their respective tracks to their respective open positions.
- the center door 14 may be opened by pushing either to the right or to the left in front of a door 12, 16 as desired depending upon the design of the system and the direction of incline of the track 22.
- the center door 14 opens to the right, as indicated by the arrow 30 by pushing the door to the right along its inclined upper track 22. When fully open, the door 14 will position directly in front of the right door 16.
- eachdoor 12, 14, 16 is provided with one or more respective bottom guides 32, 34, 36 which are slidingly associated within the bottom track 38 to guide the redoors are moved to either their open or closed positions.
- the bottom track 38 is preferably fabricated of high impact PVC plastic and extends entirely across the bottom at the front of the refrigerated cabinet 18 for door guide purposes.
- the bottom track 38 registers beneath the upper tracks 20, 22, 24 and is fabricated to provide two horizontally spaced,'elongate grooves 40, 42 which are defined between the respective bottom track forward wall 44 and the center wall 46 and the bottom track center wall 46 and the rearward wall 48.
- the bottom guide 34 of the center door 14 horizontally rides within the forward bottom track groove 40.
- the bottom guides 32, 36 of the respective left and right doors l2, l6 horizontally ride withinthe rearward bottom track groove 42. It will be noted that although there are three doors 12, 14, 16 provided in the assembly, only two bottom track grooves 40, 42 are required.
- the doors 12,14, 16 are conventionally provided with one or more respective upper hangers 50, 52, 54'which are conventionally affixed to the doors 12, 14, 16 in well known manner, such as by applying rivets or bolts 56,-58, 60.
- Each upper hanger 50, 52, 54 is provided with means to journal the respective upper rollers 62, 64, 66 for door sliding purposes.
- Sufficient rollers are conventionally employed to permit horizontal, sliding motion of the doors 12, 14, 16 in well known manner in the directions indicated by the arrows 26, 28, 30.
- the upper rollers 62 of theleft door 12 ride within the left door upper track 20.
- the upper rollers 64 of the center door 14 ride within the center upper door track 22.
- the upper rollers 66 of the right door 16 ride within the right door upper track 24.
- the upper rollers 62, 64, 66 may be fabricated of nylon or other hard, plastic material and the upper tracks 20, 22', 24 may be fabricated of stainless steel or other corrosion resistant metal in a manner well known to those skilled in the art. I
- the center door upper track 22 positions at the front of the track assembly 68 and has its roller engaging rail 70 opening rearwardly.
- the left door upper track 20 positions at the rear of the track assembly 68 and has its rolle'r engaging rail 72 opening forwardly.
- the right door upper track 24 positions intermediate the left and center door tracks 20, 22 and has its roller engaging rail 74 opening rearwardly in the same direction as the center door upper track.
- a gravity closing door system for enclosing the front opening of a cabinet, the opening having a clear width defined between a right jamb member and a left jamb member and a height defined between a head and a sill
- the combination of A. more than two doors comprising at least a left door, a right door and a center door closing the front opening, said doors being arranged in side by side horizontal juxtaposition, said doors having horizontal movement within the front opening, and each door having upper hangers including rollers,
- said upper track system including an inclined track for each door, a. the rollers of each door positioning in rolling engagement within one said inclined track;
- said bottom track comprising a pair of horizontal, spaced, elongate grooves, namely, a forward groove and a rearward groove,
