n os noaan nam** ιρηη A device for raising the seat of a closet Willi Le*on Lambert Johan Nicolaas Schutterop As the lower pressure member is locked in the upper position the pedal may be released after the seat is raised while the seat will still remain in its raised position. Of oourse, in order to lower the seat;, again the look should be released. If this would be forgotten, it would be possible that another person would try to lower the seat by hand.

However, the application of the spring member prevents any damage of the ' mechanism in that oase.

Aooording to a preferred embodiment of the invention the guide ' member oomprisea a sleeve supporting two diametrioally positioned horizontal studs near its lower end, said studs each being mounted in a bearing, so that the sleeve may pivot about a horizontal axis, said oontrol member consisting of a rod which is rigidly oonneoted to the upper pressure member and whioh is hinged to the seat.

If the pedal consists of a two-armed lever rotatable about a : central horizontal axis in a manner known per se said sleeve may have a slot at its lower end directed perpendicular to the axis of rotation, said slot receiving the free end of said lever, so that the lever may engage, the lower side of the lower pressure member. :·· . ·· Aocording to an advantageous embodiment said rod and said upper, pressure member are sealed with respeot to the sleeve, so! that the upward movement of the seat is retarded by a compression of the air present in the upper part of the sleeve.

The lower pressure member may be looked by means of a horizontal pin whioh' passes through the slot in the sleeve and whioh cooperates with a spring-biased lock on the outer side of the sleeve.

For this purpose a flat look may be applied, whioh cooperates with a torsion spring, said look having a main plane extending perpendicular to said pin and comprising a guide surfaoe cooperating with said pin and communicating with an inner reoess via a bevelled downwardly directed notoh, so that the pin upon attaining the uppermost position snaps into the notch, engages the upper wall thereof and stops the lower pressure member, whilst upon release of the pedal the pin oomes to rest on the lower side of the reoess and keeps the lower pressure member in the upward position.

A devioe wherein a simple release of the lower, pressure member is obtained is oharaoterized in that, upon renewed actuation of the pedal, '. the pin engages the upper side of the reoess, whilst, upon release of the, · pedal, said pin engages a guide surface, which is bent outwardly out of ' the plane of the look, so that the look is displaced outwardly and the pin may pass- said look, the device returning to its initial position under ; the influence of the weight of the seat. .

Preferably, said spring member consists of a helical spring mounted between said pressure members. have to , ' If, apart from the seat a cover is applied, the latter will be raised simultaneously with the seat. It would be advantageous to construct, the devioe in suoh manner, that,upon aotuation of the pedal, the oover passes the dead centre position but the seat stops before the dead centre position is reached. When the pedal of such construction is actuated again V '; the seat will lower under the influence of its own weight but the cove will remain in the raised position. j This problem may be solved in two different manners.

Aooording to a first embodiment the oover cooperates with a spring oonneoted to the seat hinges and tensioned by the weight of the cover, said spring maintaining the oover spaced from the seat, so that! the cover in the lowered position spaoedly floats above the seat, said spring being relieved when the seat is raised, so that the cover is pivoted past the dead oentre position. ; . j .

* In a second embodiment said rod is provided with: an axial bore : wherein a second actuating rod is slidably mounted, said second actuating rod being rigidly connected to [the lower pressure member and effecting the raising of the oover.

The invention will now be further desoribed with referenoe to . the drawings whioh show two embodiments thereof by way of example. ' Fig. 1 shows a side view of a closet pan provided with a device for raising the seat. ·' .'· Fig. 2 shows a vertioal section of the seat raising device.

Fig. 1 shows a closet pan 1 provided with a seat 2 and a' obver 3* Spring pressure is exerted on the oover 3 n its lowered position and maintains the oover and the seat spaced from each other, so that the oover seems to float above the seat. The seat 2 is hingedly connected to a. rod 4· When this rod is lifted the seat 2 and the cover 3 a e pivoted upwardly together, the seat 2 stopping before its dead centre position is reached, but the oover 3 passing its dead centre position. The raised position of the. " seat and of the oover are shown in dash lines. A pedal housing 5 with a pedal 6 protruding therefrom is positioned at the right-hand side of the oloset pan. Upon a first actuation of the pedal 6 the rod 4 is moved up-wardly, so that the seat is raised and is looked in its upper position. Upon a seoond aotuation of the pedal 6 the seat is released and is lowered under the influence_ of its own weight. However, the cover maintains its raised position and may be lowered by hand, if desired. The. ooupling means between the pedal 6 and the rod 4 are mounted in a sleeve17· ;■'■"■''/■ ■:''· As shown in fig. 2 the pedal 6 oonsists of a two-armed lever ¾ oonneoted to a central horizontal cross shaft 8. This shaft 8 is journalled ,■'■· in two forked bearings 9 made of elastio artifioial material. The pedal together with its bearings are inserted in the pedal housing from the left-hand side, during whioh operation the forked ends of the bearings are pressed together until two recesses in each bearing engage block-shaped protrusions 10 of the pedal housing, whereafter the bearings are locked.

The sleeve 7 · which is substantially 'made of artifioial material . .. may rotate about a horizontal axis and is journalled in the pedal housing n the same manner as the pedal 6. For this purpose the:sleeve 7 s provided on both sides with a stud 1 1 (fig., 4)» whioh is supported in a forked bearing 12 of elastic artifioial material, whilst recesses in each'. bearing 1 2 are in engagement with block-shaped protrusions of the pedal housing. The pedal housing has a large opening 1 3 at its upper side in order to enable the sleeve to pivot. This opening 1 3 is covered by a cap 14 oonneoted to the sleeve. The part of the sleeve 7 beyond the pedal housing is provided with a metal covering 1 5 · The lower part of the sleeve 7 is provided with a slot on both sides in order to enable the. pedal 6 and the.

Two pressure members, viz. a lower pressure member 6 and an upper pressure member 17 are mounted in the sleeve 7 · The -lower pressure member 16 , whioh is made of- 'artificial material has a substantial cylindrical shape, but is provided at the left-hand side(in fig. 4) with a slot. The pressure member 16 oomprises an intermediate .bottom 18, which is inj engagement with the free end of the pedal 6. Further, a locking .pin 1 9 is fitted ' . . J in this intermediate bottom 18. j ' The upper pressure member 17 consists of a metal hollow cylinder. ' The rod 4 oomprises an enlarged portion 20 which is screwed in the pressure - " member 17 · Further, the pressure member 17 is provided with a oovering 21 of artifioial material extending from its upper end to approximately half . . ■ ■ · · ; ' ·- . . - . 'r. its height. Λ rotation of the pressure member 17 with respect to the | sleeve 7 is prevented by a cam 22 on the pressure member 171 which is - in engagement with a slot 23 in the sleeve 7 · The pressure members 1 6 and 17 are ooupled together by means of a helical spring 24. This spring rests with its lower end on the pressure member 16 and engages the covering 21 of the pressure member 17 with its : upper end.

When the pedal 6 is pressed downwardly by foot' the pressure member 16 is lifted and locked in its upper position. Curing this upward movement of the pressure member 1 6 the spring 24 is brought under tension. During the following relief of the spring 24 the upper pressure member 17 ; together with the rod 4 are lifted, so that the seat 2 is raised. This movement of the seat 2 is retarded by the air present in the upper portion of the sleeve 7 · which can escape only slowly. In this manner the advantage is obtained that the seat is uniformly raised independent of the force exerted on the pedal 6 , so that damage of the mechanism due to rough treat* ment is effectively avoided. Upon a second aotuation of the pedal the lower pressure member 16 is released, whereafter the seat lowers again under the influenoe of its own weight.

As shown in fig, 3 the seat 2 and the cover 3 are pivotally mounted on the oloset pan 1 in the usual manner by means of hinges 23. The hinges 25 are eaoh provided . t the inner side with a hole having an oval cross section and reoeiving an oval projection of an insert 26 , so that thi insert is looked against rotation with respeot to the hinge. A U-shaped : spring 27 is mounted between the inserts 26 , the ends of this spring being j : reoeived in holes in the inserts. Both inserts are interconnected by a rod, whioh may be passed from the upper side via slots into the oval holes in • .the hinges 25. The web of the spring 27 presses against the oover and keeps the oover epaoed from the, seat. ' When the oover is lowered the spring 27 is reoess 37 as shown .in fig. 7 » so that the pressure member 1 6 is kept in its upward position and the seat is maintained in its raised position. Th pedal 6 returns, to its initial position by its own weight or by means of a return spring.

' ' For. lowering the seat the pedal is again actuated, so that the pressure member 1 6 is lifted somewhat higher than the position shown in fig. 7 · Now the pin 1 9 engages the upper side of the reoess 57. Upon release of the pedal the pin 1 9 engages a guide surface 3 which is bent outwardly out of the plane .of the lock, so that the look is pivoted outwardly. For this purpose the lock is journalled on.the shaft 31 with some play. Due to this pivotal movement of the look the pin 1 9 may pass the look, whereafter the pressure member 16 returns to its initial position. As the spring 24 is now relieved the pressure member 17 moves downwardly due to the weight of the. seat. However, the movement of the seat is still somewhat retarded by the spring.24 , so that the seat slowly returns to th horizontal position without any danger of damage.

Fig. 8 shows a modification wherein the raising movement of the cover is effected in a differen manner. In this embodiment the rod 4 i provided with an axial bore wherein a second actuation rod 4 is slidabl mounted. This rod 0 is screwed in the lower pressure member 16 and effec the raising movement of the cover. When the pedal is actuated the rod 40 is lifted simultaneously with the lower pressure member, so that the cove is' raised independently of the 'movement of the seat, ί . L;;V
