  • the type of cabinet door with which the support of the invention will have its greatest use is that pertaining to recreational vehicles wherein overhead storage cabinets have hinged cabinet doors within which various supplies are stowed.
  • prior art door supports of one type or another are either very sophisticated in their structures and thereby relatively expensive or alternately employ a positive locking mechanism which must be manually disengaged by a separate unlocking motion prior to closing the cabinet door.
  • a relatively low-cost, easily installed and operated door support is provided which overcomes the prior art deficiencies and which permits locking the cabinet door in the locked position and releasably unlocking the door so as to be able to close same with the exertion of an applied force to overcome the locking forces retaining the cabinet door or the like in the open or locked position.
  • Another object of the invention is to provide a door support or the like having a minimum inward projection into the cabinet when the door is closed so as to prevent interference with the contents contained in the cabinet.
  • the invention pertains to a cabinet door support or the like involving a first attachment member for secured attachment to one of a cabinet door and a cabinet frame member.
  • An elongate extending housing member is pivotally secured to the first attachment member and a second attachment member is slidably, captively and telescopically received within the housing member and has one of its ends adapted for secured attachment to the other of a cabinet door and a cabinet frame member.
  • the housing member and secured attachment member have cooperative locking or latching means to releasably lock the second attachment member in the fully extended position with respect to the housing member.
  • FIG. 1 is a schematic illustration of one type of cabinet with which the support member of the invention may be utilized;
  • FIG. 2 is a fragmentary, cross-sectional view taken along the line 22 of FIG. 1 further illustrating the door support or the like member of the invention
  • FIG. 3 is a view similar to FIG. 2, but showing the cabinet door in the open and latched or locked position;
  • FIG. 4 is a view taken along the line 44 of FIG. 3;
  • FIG. 5 illustrates a securement member for the door support with the housing and other securement member removed for purposes of clarity

  • a cabinet door 8 by means of hinges 10.
  • an interior, vertical cabinet frame member 12 in order to give rigidity to cabinet 2 and to provide support structure for the support device of the invention as will be seen as the commentary proceeds.
  • the door 8 may be provided with a pull knob 14 and friction closing means, not shown, in order to keep the cabinet door 8' tightly closed as is conventional in the cabinet art. While the door support of this invention will bedescribed singularly, it will be understood that with the size of the door 8 shown in FIG. 1, that two of the support members of the invention would be desirable. Obviously, where smaller cabinet doors are utilized in various applications, only one such support member is necessary.
  • the door support comprises a first securement member 22 in this instance being made of plastic, and having a first plate-like portion 24 with the ears 26 and 28 extending therefrom.
  • the plate 22 is provided with apertures 30 for securement to one of a door frame member 12 or alternately to the door 8.
  • the first securement member 22 is secured to the inner surface of door 8 by means of wood screws-32.
  • the ear 28 has substantially planar interior and exterior surfaces.
  • the ear 26 is thicker in wall section and is provided with an interior elongated slot 36 and shaved end 38 for ease of association with the housing member component of door support 20 as will become apparent.
  • Extending from plate 22 is the stepped projection 40 which abuts against the end wall of the housing member of support 20 to provide secure engagement between first securement member 22 and the housing member as will be described.
  • Housing member 42 is an elongate member having at least wall portions forming an interior guide path within which a second securement member is disposed in captive sliding relationship as will be seen.
  • the housing member 42 has a first end 44 from which extends stub shaft 46 for pivotal association with the slot 36 of car 26 of first securement member 22.
  • the side wall 48 of housing member 42 and from which stub shaft 46 extends has a V-shaped or triangular-like shaped tab portion 50 formed from the side wall and extending inwardly thereof.
  • the lower wall portion 52 in conjunction with an opposite lower wall portion 54, provides an interior guide path within which a second securement member is slidably disposed in captive relationship to the housing 42 as will become apparent.
  • the interior surface 56 of wall 48 is provided with a spaced pair of upraised guide rails 58 against which the second sliding securement member of the support 20 bears'agains't.
  • An inwardly directed wall portion 60 of wall 54 (FIG. 4) is also provided to bear against the second securement member which is slidably disposed within the housing member 42.
  • the inwardly directed tab portion 50 has a cross-sectional configuration (FIG. 7), to fit in close engagement with the seconcfsecurement member which is slidably disposed in housing member 42.
  • housing member 42 is fabricated of molded plastic or the like, so that theinwardly directed portions 50 and 60 have some give" or flexibility so as to allow the placement of the slidable member of door support 20 in a facile fashion.
  • the second securement member 62 which is slidably disposed within the housing member 42, is, in this particular instance, made of metal wherein a first end 64 has an abutment or formed protuberance 66 so that the abutment 66 engages the inwardly directed wall portion 60 to limit outward movement of second securement member 62 outwardly of housing member 42.
  • the member 62 is easily received and disassociated from the housing member 42 bytaking the inwardly directed wall portion 60 out of engagement with abutment 66.
  • pressure need not be relieved on inwardly directed wall portion 60 as there is provided, the sloping portion 68 adjacent the protuberance 66.
  • the end 64 and more specifically, in the area of protuberance 66, may be provided with aperture 70 through the thin wall of second securement member 62.
  • the second securement member 62 is captively received therein and is movable from the fully retracted position shown in FIG. 2 to the fully extended position shown in FIG. 3.
  • the plate 22 or alternately the securement of the end 72 of second securement member 62 to the frame member 12, will prevent further movement of the member 62 within the housing 42.
  • second securement member 62 is offset and is secured to the frame member 12 by means of screw 74.
  • the surface of member 62 adjacent the tablike wall portion 50 has a central recessed area 76 extending from about the offset end 72 to the opposite end 64 with the exception of the portion 78 adjacent the protuberance 66 which is slightly raised to form the looking or latching feature of support 20 by reason of the tab 50 engaging the end 80 of upraised portion 78.
  • the undersurface of member 62 is the reverse of the surface just described in that wherever the recessed surface 76 appears, the opposite surface is upraised as for example, as is obtained when a metal part is stamped, so that a recess is on one surface and an upraised surface is on the opposite surface.
  • the ends 80 and 82 of the upraised surface of member 62 are sloped so as to permit passage of the tab-like wall portion 50 over the upraised portion 78 to permit locking and latching or conversely unlatching and unlocking of the second support member 62 with respect to the housing and to thereby close or open the cabinet door 8 by one movement.
  • the housing member may be of molded plastic and to associate the slide member 62, one merely positions the same within the end of the housing opposite the stub shaft 46 and pushes same until the abutment 66 bypasses inwardly directed wall 60.
  • the inwardly projecting tab 50 will hit the inclined surface 80 (FIG. 4) and the continued application of pressure as previously described for closing the door 8, will cause tab 50 to override the upraised portion 78 of second securement member 62 and the member 62 will then be slidably and captively retained within housing member 42.
  • the housing member carrying the sliding member 62 is snapped into engagement by reason of cooperation of the stub shaft 46 and elongate slot 36 of first securement member 22.
  • Proper positioning of the housing member 42 with first securement 22 is obtained by reason of abutment 40 bearing against a curved edge 81 of housing member 42.
