This invention relates, as indicated, to a toilet seat and
lid assembly and more particularly to the 'hinge assembly
pivot-ally mounting the lid and seat relative to each other
as well as to the commode.

the commode having the two apertures 5 and 6 therein

seen that the hinge post 22 is provided with ‘a knuckle
27 having a through~bore 28 therein of a diameter
slightly larger than the reduced diameter ends of the
hinge bar 14. Thus the hinge posts are readily axially
adjustable along the hinge bar to accommodate com
modes having the holes 5 and 6 therein spaced at varying
distances. Moreover, the provision of the throughbore
facilitates the disassembly of the hinge posts from the com
plete lid and seat assembly to provide an easier and
smaller shipping package. In a conventional seat and
lid assembly, the hinge posts cannot readily be removed
without disassemblying the entire assembly and the
package required for shipping such an assembly will of

bores 28 and 37 in the hinge post and seat knuckle re
spectively. The leaf 41 of the lid knuclde is offset up
wardly and provided with a top planar surface 432 to which
the bottom of the lid 8 is secured. Such leaf portion 41
may be the same planar shape as the leaf 33 of the seat
knuckle shown in FIGS. 4 and 5 and is provided with
two countersunk screw holes 43 to facilitate the fastening
of the lid knuckle to the lid 8 by the screws 21. Supports
44 on the underside of the front of the lid will serve to
space the lid from the seat and maintain the same gen
erally parallel to the seat '7.
It can now be seen that I have provided a toilet seat
and lid assembly which can be shipped in a carton con~

to support the weight on the seat through the hinge posts

also relieve any structural stresses on the seat itself.
