Referring to the accompanying drawings, which illus-l trate the practical embodiment of my invention, 10 designates a commercial type of refrigerator cabinet or box, having

vertical side walls

11 and 12 and a bottom wall 13, and a top wall 14.

On the left vertical side of the cabinet, attached to the side wall 11 a lower hinge member 15 is secured to the refrigerator permanently, and near the upper end of the refrigerator an upper hinge member 16 is fixed on the Side wall 11, in vertical alignment with the lower hinge member 15. On the right side wall 12 a lower hinge member 17 is fixed and in the same horizontal plane as the hinge member 15 of the left side of therefrigerator, and near the upper end of this right side wall 12 another hinge member 18 is xed, in the same horizontal plane as the upper left hinge member 16 of the A left bar 21 is arranged to slide vertically against the left side of the door, and is provided with a longitudinal slot 21a near its upper end, through which a fastener or pin 22 extends to engage the door, and hold the bar 21 for limited sliding movement on the door. The bar 21 is further provided with a longitudinal slot 2lb near its lower end, through which the fastener or pin 22a extends to engage the door, to permit limited sliding movement of the bar, and to hold the bar in proper working relation rto the door. v

The lower end of the bar 21 is provided with a lateral ange 21e, through which a vertical rod 23 extends, this rod being secured at 24 to the bottom wall 19a. The rod 23 is provided on its upper end with a head 23a, which is engaged by the coil spring 25 disposed around this rod, and which engages rthe lateral flange 21e of the vertical sliding bar 21 to force this bar downwardly.

Another bar 26 is arranged to slide vertically on the right side of the door, and for this purpose is formed with a longitudinal slot 26a near its upper end and another longitudinal slot 26b near its lower end. A fastener 27 extends through the upper slot 26a and is engaged with the door, and a fastener 27a extends through the lower slot 2Gb to hold'thebar26 for'liniited'sliding-nrovement on the door.

A bar 28, having ,a head onits upper end, projects through the terminal vilange`26ii of the lower 'endofthe bar 26, and a coil spring'ZScis mounted kon'the bar 'or rod 28 and exerts pressure against'the'flateral stop flange 28d. The rod or bar '28 is secured at29 ltothe bottom wall 19a of the door.

On theileft side `ofthe door, alever '29 having a longitudinal slot 29a Vin its outer end,'is pivotally secured to the bar 21 by means `of the fastener 31, which extends through the slot 29a, andis pivotally'secured to the door bythe fastener 32. This lever has an inner arm 30 vdisposed in diagonalrelationto the outer Varm thereof, `and is lprovided with a terminal shoe or strike Ahead 34 on its inner end. A second and 'companion lever 3'5 is pivotally secured "to the sliding 'vertical bar '26 by means of the 'fastener 36, 'which extends through the longitudinal slot 35a of said lever to Yengage vsaid vertical Abar 26. This second lever has an inner arm 37, disposed in diagonal relation to the 'outer `lever 0arm, which is pivoted vvby ythe fastener 40 to the door.

Theright lever "35 is provided with a striking head 37a on the inner end -of 'the arm l37, which is designed "to abut against the striking head 34 of the lever arm 30. When the vertical sliding bar 26 is in a raised position, the outer ylever arm 3S will Vbe `raised and this will mean that the inner lever 'arm v3;7 is lowered, so that it abuts against the end of the striking head 34 of 'the lever arm 30. 'When :the verticalsliding bar 21 is raised, the outer lever arm 29 will also be raised, thereby lowering the inner lever arm 3l) and this will Acause the striking head 34 thereof to abut against the striking head 37a ofthe inner lever arm 37, and lthis will lock the sliding bar 26 against vertical movement. When the bar 21 vis locked in its lower position, the door will swing onthe left hinge members which are coupled to leach other, and when the bar 26 is locked in its lower position, the door will swing on its right hinge members.

The -movable hinge member 15a is provided with a p'intle pin which is received by the female lhinge member 1'5, fixed to the refrigerator lbox; the movable hinge vmember 16a is secured in place by an arm 16b on the upper end of the bar 21, and is provided with a pintle 16d, which is received vby the hinge member 16, xed to 'the refrigerator box. The movable hinge member 17a is provided with a pintle 17d, which is -received lby the fixed hinge member 17 of the refrigerator. The movable hinge member 18 is provided with a pintle 18d, which is received by the hinge member 18 fixed to the refrigerator. A shield e may be provided on the movable hinge member 15a to conceal the joint between the lmating hinge members 15a and 15', a shield 16e may be provided on the hinge member 16a for the same purpose; a shield 17e` may be provided on the hinge member 17a and a shield 18e may be provided on =the hinge member 18a for the same general purpose, of masking the gap lbetween the mating hinge members.

`The vertical sliding bar 21 is manually raised by means of a handle 42, which has a handhold 42b projecting above the pivot connection of the handle 42' with the door. This handle is provided with an inner hook arm 42a, which is designed to engage the small flange 41 -iixed to the sliding `bar 21. A spring 43 exerts a downward pull on the hook arm 42a, and thereby holds the handhold 42b contiguous to the front face of the door. By pulling on the handhold 42b, Ithe hook arm 42a will be raised, thereby raising the sliding bar. The sliding bar 26 is operated in the same way by the handle 44.

v Each of the sliding bars 21 Aand 26 is provided with a group of three

spring pins

48, 49 and 50 on each sliding bar. 'These pins are spaced longitudinally from each other. Each spring pin includes a housing 51, which is secured to its bar, and a plunger pin 52, which slides in the housing yand is acted on by the Icoil spring 53. vThe head ofthe pin is formed to engage in an opening52d in the inner door plate 20a, said opening being aligned with the opening 52e in the 'bar 21. When the door is opened all of the pins of the vertical sliding bar on the open side of the door will be interlocked with the door part or plate 26a. When the door is closed the spring pressed pins will be displaced from locked engagement with the door, by the action of the `tapered pins r54, fixed to the refrigerator and it will then be possible to operate the vertical With the door in an open position the movement of the spring pressed Apins'through the sliding bar on the open side'of the door, .and 'into the receiving holes of the door `plate 20a, will automatically lock this sliding bar against movement.

This safety feature is designed to prevent children from releasing the vertical sliding bar on the open side of the door when the door is in open position. Should one of the spring pins 'be Vpressed and thereby "displaced :by a child, the other'two spring pins would hold'the vertical bar '-21 or -26la`tc'hed against accidental dropping, `when it is in araisedposition.

4`I am aware Vthat doors have been kconstructed before whichopened on therig'ht or left sides, Ibut the public has not been Asatisfied with the constructions 'offered it. In some Yof :the devices which have .gone "into Ageneral use on a limited scale aesinglehandle is provided'on the door, which is located midway of the verticalsides o'f-the door, with theresult that greatereffort is required to open a door because of the central position of the handle. My invention permits of the'location'oi the handle atthe extreme sidevedge Vportion of the door, so that maximum leverage is obtained, and a child may open 'the door without unusual effort. The opening action or effort for leach side of the door -is equal to that of the other side, which provides a'balanced construction of high consumer acceptance value.

I My invention provides `for means for locking the unused sliding-vertical bar against operation, by the action of the yactive lever'on the inactive lever, and at the same time locks the handle which is operatively connected with the inactive sliding bar, and also provides means for locking :the raised sliding bar in a raised position so that the door can besafely closed, and this locking means as well as theinternal lever locking means involves an automaticV action, which does not depend on manual selection.

Various changes and adjustments may be carried out in the development and utilization of the invention, within the scope of the invention asdened by the claims.
