Abstract: 1336922 Toilet seats G W BLOUNT 24 June 1971 29718/71 Heading EIC A toilet seat construction comprises one or more covers in the form of a seat or/and seat cover which is or are pivotally mounted on the toilet bowl for movement between a lowered position resting on the bowl top and a raised position resting against a back support, wherein two stationary brackets are mounted on the bowl top at opposite sides of the bowl, each bracket having a track extending forwardly away from the back support, and wherein hinge members for pivotally mounting the or each cover are slidably accommodated in the tracks for movement between a normal rearward location and an advanced location which allows the cover or covers to occupy the raised position and lean stably on the back support. In the embodiments shown, the back support is the tank of a cistern, and the closet bowl is provided with upper and lower covers in the form of a seat and a seat cover, respectively. In the embodiment of Fig. 5, each stationary bracket 28 comprises a rear portion 31, which carries a threaded bolt portion 32 for securing the bracket to the top face 24 of a rearward extension 23 of the bowl, and a forwardly extending portion which carries a T-shaped track 34 having a forward end stop 38. A gap between the rear end of the track 34 and the portion 31 is normally blocked by a transverse rod 42 which is carried by arms pivoted on a pin 40 so that the rod can be swung to the position 42', allowing removal and refitting of hinge member 47 which has its lower portion cut to provide a recess corresponding to the shape of the track 34. Hinge member 47 includes a steadying portion 51 and is bored to receive a pivot pin 46 on which are mounted two hinge brackets. One of these brackets (53, Fig. 6, not shown) lies behind the member 47 when the seat 56 is lowered and has a forward extension which as shown is screwed to the underface of the seat 56. The other hinge bracket 57 is screwed to a seat cover 59. The seat 56 has a seat pad 61 of foam rubber or other soft cushion material mounted on it. In the embodiment of Figs. 15, 18a, the hinge member consists of two parts, viz: a sliding bracket 151 and a swinging bracket 171 which it fitted to the seat 175. A hinge pin 158 is passed through a counterbored bore in the bracket 151, through a bore in bracket 171 and into a bore in the seat 175 where it is anchored by a set screw, whereby the seat 175 and bracket 171 pivot together. A pin 181 carried by the bracket 171 provides a hinge for seat cover 182. The stationary bracket 128 is similar to that of the previous embodiment, but the T-shaped track has a gap only in the cross member, forming slots 136, 136', the web portion being continuous with the rear portion 131 to form a bridging surface 143. The recess in the bracket 151 for accommodating the track is shaped such as to allow tilting of the bracket (Fig. 22, not shown) to enable it to be removed from the track. A plate 159 is slidable vertically in a guideway in the bracket 151 for selective engagement with either of two sockets 144, 146 to lock the bracket in rearward and advanced positions respectively. A recess 168 engages projections 152 to prevent the bracket 151 from tilting when in the fully rearward position. The embodiment of Fig. 25 is similar, excepting that locking of the sliding bracket 196 is effected by pin members 224 engaging grooves 214, 216 in the track, the track having a gap to enable removal of the bracket 196.
