Fig. 7 is a perspective view of another embodiment of a lift-off hinge pin according to the invention.
Fig. 8 is a rear view of the hinge pin of Fig. 7;
and Fig. 9 is a sectional view along the line 9-9 of Fig. 7.
Reference is first made to Fig. l which shows a conventional toilet 10 having a bowl 12 and a seat 14 consisting of a ring 16 and a lid 18. The seat 14 is releas-ably and pivotally connected to a rear flange 20 of the toilet 10 by two hinge assemblies 22 and 24 constructed according to a preferred embodiment of the invention.
The hinge assembly 22 consists of z hinge block 26 and a lift-off hinge pin 2~. The hinge assembly 24 consists of a hinge block 30 which is identical to the hinge block 26 and a lift-off hinge pin 32 which is a mirror image of the hinge pin 28.
The hinge block 26 has (Figs. 2, 5, 6) a front -face consisting of a substantially vertical lower section 33 and an upwardly and forwardly sloping upper section 34, a -~
rear face consisting of a substantially vertical section 36 ' and an upper face consisting of an inclined frontwardly-;, facing section 38 (Fig. 5) and an inclined rearwardly-facing section 40.
The hinge bloc]~ 26 has a hollow interior 42, as $ is best seen in Fig. 2. Access to the interior 42 is permitted `, by a rectangular entry opening 44 in the frontwardly-facing section 3~ of the upper face. Access to the interior 42 is also permitted by a rectangular release opening 46 cut away from the rearwardly-facing section 40 of the upper face and from the vertical section 36 of tlle rear face. The entry opening 44 is separated from tile release opening 46 by a rectangular bridge portion 48 which defines a retaining member.
.... , ~ .
106~76Sl The base 50 of the hinge block 26 is flat so that it may rest on the toilet flange 20. The base 50 includes a bolt opening 52 which is located beneath the release opening 46 so that a threaded bolt 54 can be inserted through release opening 46 into bolt opening 52. Since the bridge portlon 48 interferes slightly with the head 56 of the bolt 54, the bolt opening 52 has sufficient clearance for the bolts 54 so that the bolt 54 can be inserted at an angle into opening 52 and then can be straightened.to a vertical position after the bolt head 56 has passed below the bridge portion 48. (Alternatively the angle between the section 40 and the horizontal can be decreased and the section 40 lengthened slightly so that the bridge portion 48 will be located forwardly of the bolt head 56.) To fasten the hinge block 26 to the flange 20, the bolt 54 is passed through opening 52 and through a similar bolt hole 57 in the flange 20 and is then secured with a wing nut 58.
The lift-off hinge pin 28 of the hinge assembly 22 has a head portion 62, a pin portion 64 and a clip portion : defined by a first jaw member 66 and a second jaw member 68.
The head portion 62 has a planar base surface 70 and two opposed, planar, parallel side surfaces, one of which is indicated at 72 in Fig. 1. The jaw members 66 and 68 are spaced apart and are substantially parallel and extend in a substantially perpendicular direction from the base surface 70. The pin portion 64 extends in a substantially perpen- :
dicular direction from the side surface 72. The jaw members 66 and 68 are substantially perpendicular to the pin portion 64. Preferably, the first jaw member 66 is disposed upwardly of, and is slightly longer than, the second jaw member 68.
, ...................... .
~067651 The perpendicular spacing dl (Fig. ~) between the outwardly-facing surface of the first jaw member 66 and the outwardly-facing surface of the second jaw member 68 is preferably slightly greater than the perpendicular height d2 of the entry opening 44.
The first jaw member 66 is provided with a rectang-ular notch 74 extending laterally across its outwardly-facing surface adjacent to the base surface 70 of the head portion 62. The width of the notch 74 is equal to or very slightly greater than the width of the retaining member 48 of the hinge block 26 (Fig. 3). The first jaw member 66 is therefore more pliable than the second jaw member 68 and may be easily cantilevered towards the jaw member 68 upon the application to its outwardly-facing surface of an inwardly ;
directed force.
The lift-off hinge pin 32 of the hinge assembly 24 differs from the lift-off hinge pin 28 of the hinge assembly 22 only in that its pin portion 76 extends from a side surface (not visible) corresponding to the left hand side surface of the head portion 62.
The lift-bff hinge pin 28 is mated to the hinge block 26 by inserting the jaw members 66 and 68 into the entry opening 44. Since the first upper jaw member 66 is preferably longer than the second lower jaw member 68, it is inserted into the entry opening 44 first and is cantilevered inwardly by pressing on its outwardly-facing surface to decrease the spacing between its outwardly-facing surface , and the outwardly-facing surface of the lower jaw member 68`~ (Fig.2) so that it is possible to insert the lower jaw member 68 7nto the entry opening 44.
.
.`~ ~ . ,, . ~ .
If the lower jaw member 68 is provided with a bevelled end portion 78, it is not necessary to press down-wardly on the outwardly-facing surface of the first upper jaw member 66 since the bevelled end portion 78, as it slides into the entry opening 44, causes the upper jaw member 66 to deflect inwardly towards the lower jaw member 68.
The jaw members 66 and 68 are inserted into the entry opening 44 until the notch 74 passes under the retain-ing member 48, at which time the upper jaw member 66 springs upwardly and the retaining member 48 engages the notch 74.
When the notch 74 is in engagement with the retaining member 48, the outwardly-facing surface of the upper jaw member 66 is readily accessible through the release opening 46. To disengage the notch 74 from the retaining member 48, the first upper jaw member 66 is deflected inwardly towards the second lower jaw member 68 by pressing on its outwardly-facing surface, thereby allowing the jaw members 66 and 68 to be removed from the entry opening 44.
The hinge assemblies 22 and 24 may be used with many conventional toilets simply by replacing the hinge members connecting a seat to the toilet with the present hinge assemblies, the pin portions 64 and 76 being inserted into socket p~rtion 8C of the seat. The pin portions 64 and 78 are preferably made long enough so that both ring 16 and lid 18 of the seat 14 can pivot on them.
, The hinge assemblies 22 and 24 are preferably injection molded from polyethylene or other appropriate plastic.
Various modifications may be made to the hinge assemblies 22 and 24. For instance, the orientation of the assemblies 22 and 24 may be reversed so that the entry slot 7 _ 106765~L ~
opening 44 faces rearwardly rather than frontwardly. In the frontward orientation, the release opening 46 may be disposed on the front face below the entry opening 44, in which case the first jaw member 66 having the notch 74 would be disposed below the second jaw member 68. In that event the bolt 54 is preferably molded integrally with the hinge block 26.
Reference is next made to Figs. 7, 8, and 9 which show a slightly modified hinge pin 82 according to the invention. The hinge pin 82 differs from hinge pin 28 only in its clip portion 84. Clip portion 84 includes a first , upper long jaw member 86 and a second short lower jaw member 88 which is reinforced by two side members 90 molded integ~
rally with the jaw member 88 to form a kind of three sided box structure. This arrangement gives great rigidity to the lower jaw member 88 while permitting use of relatively thin plastic, and ensures that all the flexing will be performed by the flexible upper jaw number 86. The outer end of the upper jaw member 86 may be provided with transverse serrations 92 on its outer surface to assist the user in depressing this surface and sliding it.

Fig. 7 is a perspective view of another embodiment of a lift-off hinge pin according to the invention.
Fig. 8 is a rear view of the hinge pin of Fig. 7;
and Fig. 9 is a sectional view along the line 9-9 of Fig. 7.
Reference is first made to Fig. l which shows a conventional toilet 10 having a bowl 12 and a seat 14 consisting of a ring 16 and a lid 18. The seat 14 is releas-ably and pivotally connected to a rear flange 20 of the toilet 10 by two hinge assemblies 22 and 24 constructed according to a preferred embodiment of the invention.
The hinge assembly 22 consists of z hinge block 26 and a lift-off hinge pin 2~. The hinge assembly 24 consists of a hinge block 30 which is identical to the hinge block 26 and a lift-off hinge pin 32 which is a mirror image of the hinge pin 28.
The hinge block 26 has (Figs. 2, 5, 6) a front -face consisting of a substantially vertical lower section 33 and an upwardly and forwardly sloping upper section 34, a -~
rear face consisting of a substantially vertical section 36 ' and an upper face consisting of an inclined frontwardly-;, facing section 38 (Fig. 5) and an inclined rearwardly-facing section 40.
The hinge bloc]~ 26 has a hollow interior 42, as $ is best seen in Fig. 2. Access to the interior 42 is permitted `, by a rectangular entry opening 44 in the frontwardly-facing section 3~ of the upper face. Access to the interior 42 is also permitted by a rectangular release opening 46 cut away from the rearwardly-facing section 40 of the upper face and from the vertical section 36 of tlle rear face. The entry opening 44 is separated from tile release opening 46 by a rectangular bridge portion 48 which defines a retaining member.
.... , ~ .
106~76Sl The base 50 of the hinge block 26 is flat so that it may rest on the toilet flange 20. The base 50 includes a bolt opening 52 which is located beneath the release opening 46 so that a threaded bolt 54 can be inserted through release opening 46 into bolt opening 52. Since the bridge portlon 48 interferes slightly with the head 56 of the bolt 54, the bolt opening 52 has sufficient clearance for the bolts 54 so that the bolt 54 can be inserted at an angle into opening 52 and then can be straightened.to a vertical position after the bolt head 56 has passed below the bridge portion 48. (Alternatively the angle between the section 40 and the horizontal can be decreased and the section 40 lengthened slightly so that the bridge portion 48 will be located forwardly of the bolt head 56.) To fasten the hinge block 26 to the flange 20, the bolt 54 is passed through opening 52 and through a similar bolt hole 57 in the flange 20 and is then secured with a wing nut 58.
The lift-off hinge pin 28 of the hinge assembly 22 has a head portion 62, a pin portion 64 and a clip portion : defined by a first jaw member 66 and a second jaw member 68.
The head portion 62 has a planar base surface 70 and two opposed, planar, parallel side surfaces, one of which is indicated at 72 in Fig. 1. The jaw members 66 and 68 are spaced apart and are substantially parallel and extend in a substantially perpendicular direction from the base surface 70. The pin portion 64 extends in a substantially perpen- :
dicular direction from the side surface 72. The jaw members 66 and 68 are substantially perpendicular to the pin portion 64. Preferably, the first jaw member 66 is disposed upwardly of, and is slightly longer than, the second jaw member 68.
, ...................... .
~067651 The perpendicular spacing dl (Fig. ~) between the outwardly-facing surface of the first jaw member 66 and the outwardly-facing surface of the second jaw member 68 is preferably slightly greater than the perpendicular height d2 of the entry opening 44.
The first jaw member 66 is provided with a rectang-ular notch 74 extending laterally across its outwardly-facing surface adjacent to the base surface 70 of the head portion 62. The width of the notch 74 is equal to or very slightly greater than the width of the retaining member 48 of the hinge block 26 (Fig. 3). The first jaw member 66 is therefore more pliable than the second jaw member 68 and may be easily cantilevered towards the jaw member 68 upon the application to its outwardly-facing surface of an inwardly ;
directed force.
The lift-off hinge pin 32 of the hinge assembly 24 differs from the lift-off hinge pin 28 of the hinge assembly 22 only in that its pin portion 76 extends from a side surface (not visible) corresponding to the left hand side surface of the head portion 62.
The lift-bff hinge pin 28 is mated to the hinge block 26 by inserting the jaw members 66 and 68 into the entry opening 44. Since the first upper jaw member 66 is preferably longer than the second lower jaw member 68, it is inserted into the entry opening 44 first and is cantilevered inwardly by pressing on its outwardly-facing surface to decrease the spacing between its outwardly-facing surface , and the outwardly-facing surface of the lower jaw member 68`~ (Fig.2) so that it is possible to insert the lower jaw member 68 7nto the entry opening 44.
.
.`~ ~ . ,, . ~ .
If the lower jaw member 68 is provided with a bevelled end portion 78, it is not necessary to press down-wardly on the outwardly-facing surface of the first upper jaw member 66 since the bevelled end portion 78, as it slides into the entry opening 44, causes the upper jaw member 66 to deflect inwardly towards the lower jaw member 68.
The jaw members 66 and 68 are inserted into the entry opening 44 until the notch 74 passes under the retain-ing member 48, at which time the upper jaw member 66 springs upwardly and the retaining member 48 engages the notch 74.
When the notch 74 is in engagement with the retaining member 48, the outwardly-facing surface of the upper jaw member 66 is readily accessible through the release opening 46. To disengage the notch 74 from the retaining member 48, the first upper jaw member 66 is deflected inwardly towards the second lower jaw member 68 by pressing on its outwardly-facing surface, thereby allowing the jaw members 66 and 68 to be removed from the entry opening 44.
The hinge assemblies 22 and 24 may be used with many conventional toilets simply by replacing the hinge members connecting a seat to the toilet with the present hinge assemblies, the pin portions 64 and 76 being inserted into socket p~rtion 8C of the seat. The pin portions 64 and 78 are preferably made long enough so that both ring 16 and lid 18 of the seat 14 can pivot on them.
, The hinge assemblies 22 and 24 are preferably injection molded from polyethylene or other appropriate plastic.
Various modifications may be made to the hinge assemblies 22 and 24. For instance, the orientation of the assemblies 22 and 24 may be reversed so that the entry slot 7 _ 106765~L ~
opening 44 faces rearwardly rather than frontwardly. In the frontward orientation, the release opening 46 may be disposed on the front face below the entry opening 44, in which case the first jaw member 66 having the notch 74 would be disposed below the second jaw member 68. In that event the bolt 54 is preferably molded integrally with the hinge block 26.
Reference is next made to Figs. 7, 8, and 9 which show a slightly modified hinge pin 82 according to the invention. The hinge pin 82 differs from hinge pin 28 only in its clip portion 84. Clip portion 84 includes a first , upper long jaw member 86 and a second short lower jaw member 88 which is reinforced by two side members 90 molded integ~
rally with the jaw member 88 to form a kind of three sided box structure. This arrangement gives great rigidity to the lower jaw member 88 while permitting use of relatively thin plastic, and ensures that all the flexing will be performed by the flexible upper jaw number 86. The outer end of the upper jaw member 86 may be provided with transverse serrations 92 on its outer surface to assist the user in depressing this surface and sliding it.
