Definitions

  • This invention relates to closures for the filling opening of a soap dispenser for a washfountain, or for other applications where is it necessary to close off an opening through a wall member; and it resides more particularly in the combination with a wall having an aperture therethrough of a rotatable cap disposed on one side of the wall and engageable therewith; a locking bar disposed on the other side of the wall; means to hold the bar and cap against relative rotation while allowing them to move toward and away from one another; ramp means cammingly engageable with the bar to move the bar away from the cap as the cap is rotated; bias means to urge the cap and bar together; and lock means to move the cap and bar toward one another.
  • Closures formed accordingly to this invention are particularly useful in connection with soap dispensers for group washfountains such as those commonly provided in schools and industrial plants.
  • washfountains usually comprise a large basin and a central, 360 sprayhead for simultaneous use by a number of persons.
  • a soap dispenser is often mounted above the sprayhead and usually comprises a reservoir for powdered or liquid soap and any suitable number of individual valves or other dispensing means, It is of course necessary to refill the reservoir at frequent intervals, and to this end the cover of the reservoir is usually provided with a filling opening with a suitable removable closure.
  • FIG. 1 is a fragmentary top plan view of the top wall of a soap dispenser showing a closure, formed according to this invention, in place,
  • FIG. 2 is a bottom plan view of the closure of FIG. 1,'
  • FIG. 3 is a bottom plan view of the closure of FIG. 1 that is similar to FIG. 2, but shows the cap and locking bar in a closed position,
  • FIG. 4 is a view in cross section taken along the plane 4l4 shown in FIG. 1,
  • FIG. 5 is a fragmentary View in cross section taken along the plane 55 shown in FIG. 3, and
  • FIG. 6 is a fragmentary view in cross section taken along the plane 5-6 shown in FIG. 2.
  • the reference numeral 1 refers to the plastic top wall or cover of a soap dispenser or similar receptacle (not shown).
  • the closure of this invention is useful in a wide variety of applications. For this reason, and since the structure and operation of the closure can be understood without reference to any particular receptacle or other structure, the soap dispenser has not been shown ordescribed herein.
  • a soap dispenser in which a closure formed according to this invention may be used, reference may be had to US. Patent No. 2,376,551 issued May 22, 1945 to H. G. Mullett et al.
  • the wall 1 has a substantially circular aperture therethrough which is provided with a pair of substantially diametrically opposite, generally rectangular cutout portions or recesses 3 which serve as lateral extensions of the aperture 2.
  • the underside of the wall 1, that surface seen in FIGS. 2 and 3, is provided with an integral upstanding rim 4, which extends about substantially the entire circumference of the aperture 2 except for those portions occupied by the recesses 3.
  • the underside of the wall 1 is also provided with a pair of integral ramp means 5 which extend outwardly from the rim 4.
  • the ramp means 5 begin near opposite sides of the recesses 3, with each ramp 5 extending from a point near its associated recess 3 and thence about the circumference of the aperture 2 to terminate approximately on a line perpendicular to a line drawn between the recesses 3.
  • Each ramp 5 beings at the level of the rim 4. and inclines outwardly from the wall 1 to an apex 6 intermediate its ends. From the apex 6, each ramp 5 is provided with a reverse incline toward the wall 1 which continues until the ramp 5 terminates at an upstanding stop projection 7.
  • the two ramps 5 are substantially diametrically opposite; that is, they have their corresponding points substantially on opposite sides of the center of recesses 3.
  • the rims 4 and 9 serve to strengthen the wall 1.
  • rims such as the rims'4 and'9, are also useful in providing flat operating and sealing surfaces about the aperture 2. It can beseen from FIG. 4,'that the aperture 2 tapers outwardly slightlyxfrom the bottom of the wall 1, which is actually the top of the rim 4!, to the top of the rim 9.
  • a generally circular, plate-like plastic cap 10 engages the upper surface of'the wall 1, the surface seen in FIG. 1, with. the outer edge of its inner side in sealing contact with the rim h, the cap 10 thus serving to close off the aperture 2;
  • the edge of the cap 10 is beveledor tapered inwardly from top to bottom for ease in handling as will be described.
  • The'cap 510 is provided on its bottom or inner side with a pair'of integral downwardly extending, substantially diametrically opposite projections 11 each provided with a downwardly opening, fiat bottomed notch 12. At about the center of the cap 10, intermediate the projections 11, there is a downwardly extending integral block 13 having a smooth, vertical stepped bore 14 extending therethrough.
  • a lock meansin the form of a threaded screw 15, having an operating head 16 is slidably and rotatably received through the bore 14 with the head 16 being received in the relatively larger upper portion of the bore 14, as can be seen in FIG. 4.
  • a compression spring 17 is seated in'theintermediate portion of the bore 14 and acts between the floor of the intermediate portion of the bore 14 and the head 16 to urge the screw in an-upward direction as seenin FIG. 4.
  • a generally rectangular metal locking bar 18 is threadedly mounted on the downwardly projecting end of the screw 15, the-bar-18thus being mounted on or connected to the cap 10."
  • the lower end of the screw 15 is provided with a groove which receives a lock washer 19 which prevents the screw-15 from being removed from'the bar 18.
  • the bar 18 is provided with narrowed end portions 20 which are received in the notches 12 of the projections 11. Because the-ends 20 are disposed in the notches 12, the bar 18-is held against rotational movement relative to the cap 10 but is allowed to move toward and away from the cap'10.
  • the projections 11 and the block 13 serve to limit movement of the bar '18 toward the cap 10.
  • the bar 18 is normally in the position shown in FIG. 4;
  • the screw 15 and bar 18 are adjusted so thatin this normal'position there is, as can be seen in FIG. 4,'a clearance between the head 16 and its seat in the bore 14. This clearance allows the bar 18 to be moved downwardly in a closing action as will be described.
  • the projections 11 and block 13 are of sufficient height so that when the bar 18 is in the normal position shown in FIG. 4 the distance between the bar 18 and the a cap 10 is slightly greater than the thickness of the wall 1,
  • the bar 18 is longer than the diameter of the aperture 2, but is shorter than the distance between theremote ends of the recesses 3 so that it can pass through the aperture 2 only when the narrowed ends 20 are in alignment with the recesses 3.
  • FIGS. 2, 3 and 5 The operation of the closure can be understood with particular reference to FIGS. 2, 3 and 5.
  • the 'cap 10 andbar 18 are placed inthe position shown in FIG. 2 wherein the ends 20 of the bar 18 are in alignment with the recesses 3.
  • the bar 18 may then be inserted through the aperture 2 and the upper surface of the bar 18 will then be slightly below the top of the rim 4.
  • the cap 19 is then rotated in a counterclockwise direction as seen in FIGS. 2 an d-3, with the engagement between the ends 29 and notches 12 causing the bar 18. llObfl rotated with theicap 10 as a unit.
  • the stops 8 prevent the cap 10 and bar-181mm being rotated in a clockwise direct-ion as seen in FIGS.' 2 and 3.
  • the cap 10 is relatively thin and is set quite close to the wall 1, being raised only by theheight of the rim 9. This substantially flush mounting would ordinarily make the cap 10 quite difficult to grasp for opening and closing.
  • the cap 10 can have a substantially flush appearance, which also reduces the possibility of catching dirt or foreign matter, while still being easy to handle.
  • the force of the spring 17 will be enough to hold the cap 10 in place.
  • the screw 15 may be used to draw the bar 18 tightly against the underside of the wall 1, the screw 15 thus serving as a screw lock means.
  • the head 16 of the screw 15 is provided with a hexagonal socket 21. The head 16 is substantially flushwith or below the top of the cap 10, so that, although rotation of the screw 15 can be accomplished readily by inserting a'suitable tool into the socket 21, manual rotation by unauthorized persons is practically impossible.
  • One of the important features of the invention is the provision of the projections 11 and notches 12 which serve to allow movement of the bar 18 toward. and away from the cap 10 to allow a camming action by the ramps 5.
  • the bar 18 is, however prevented from rotation with respect to the cap it ⁇ so that the two rotate together as a unit.
  • the notches 12 also prevent rotation of the bar 18 during tightening of the screw 15.
  • a closure the combination with a wall having an aperture therethrough of a rotatable cap disposed on one side of the wall and engageable therewith; a locking bar connected to the cap and disposed on the opposite side of the wall; means to hold the bar and cap against relative rotation and to allow the bar and cap to move toward and away from one another; bias means to urge the bar and cap together; ramp means interposed between opposite side of the wall and the bar and adapted to cause a camming engagement therebetween which moves the bar away from the cap as the cap is rotated; and lock means separate from the ramp means to move the bar and cap toward one another.
