1 Claim.
This invention relates to high chairs of the type used by book-keepers and the like, and has for its general object to produce a chair of this character having a vertically adjustable seatsupporting spindle and a foot rest carried by the spindle, the foot rest, as it is secured to the spindie, being vertically adjustable on movement of the latter, but in addition the foot rest is independently adjustable on the spindle. With a chair of this type, it will be evident that the elevation of the seat can be changed or adjusted without changing the distance between the foot rest and the seat. When necessary, however, the position of the foot rest in relation to the seat can be adjusted without affecting the height of the seat.
With the general objects named in view and others as will hereinafter appear, the invention consists in certain novel and useful features of construction and organization of parts as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accompanying drawing, in which:
Figure 1 is a front View of one form of chair having an adjustable seat and foot rest embodying the invention.
Figure 2 is a top plan View of the same with the seat omitted.
Figure 3 is an enlarged central vertical section through the vertically adjustable spindle, the upper end of the base or floor-engaging member, and the foot rest.
Figure 4 is an enlarged perspective View of the interlocking engagement between thek foot rest and the base, to prevent independent rotation of the foot rest on the spindle.
Figure 5 is a side elevation of a modified construction in which the foot rest is mounted on the spindle above, instead of below, the point of support of said spindle by the base.
In the said drawing, where like reference characters identify corresponding parts in all of the gures, the preferred form of base or floor-engaging member comprises a series of four tubular legs I, radiating outwardly at their lower ends and equipped, if desired, with rollers 2. The legs I preferably extend upwardly in nested parallel arrangement and have their upper ends rigidly secured in an inverted cup-shaped stamping or casting 3. Vertically slidable through a guide passageway in the casting 3 is a spindle 4, which may carry any suitable seat 5 swivelled on its upper end. The spindle 4 is preferably formed with a longitudinal key-way E receiving a pin 'l carried by the casting 3 to hold the spindle against rotation in the base, and the spindle is positioned in vertical adjustment by means of a spring-advanced locking pin 8 carried by the base and adapted to engage any one of a series of sockets 9 in the spindle. If desired, the lower end of the base may be provided with a step-ring 'III which will act as a reinforcement or brace for the lower radiating ends of the legs I.
Vertically adjustable on the spindle below its engagement with the casting 3 is a foot rest Il, the rear end of said foot rest being reduced at I2' for extending between a pair of the legs I (see Figure 4), the legs thus acting as stops to prevent rotation of the foot rest on said spindle.
The rear end of the foot rest terminates in a tubular casting I3 slidably receiving the spindle 4, said casting having a spring-advanced locking pin I4 for engagement with the sockets 9 in the spindle to lock the foot rest in desired vertical positions With this construction it will be evident that vertical adjustment of the seat carries the foot rest along with it, so that the two parts `maintain their relative vertical spacing.
In Figure 5, a slightly modified construction is shown in which the foot rest l5 is illustrated as in the form of a ring or circular platform.
In this construction the foot rest has a central, kcasting I6 which slidingly receives the spindle `rabove a base casting 22 supporting said spindle.
In order to lock the foot rest against rotation which would cause msalignment of its locking pin I8 in relation to the locking sockets in the vspindle, said casting carries a pin or screw I said casting I6. Yerence, the supporting legs 2i radiate from the engaged with the longitudinal slot or key-way in the spindle as previously described. It is to be noted that by reversing the position of' the foot rest I5 the casting I6 will be above instead oi' below the same, and it is then possible to space the foot rest a greater distance from the seat by a height or distance equal to the length of With this construction, by prefa spring-pressed latch carried by the base for selective engagement with the sockets to hold the spindle in vertically adjusted position, a foot rest mounted on the spindle and vertically adjustable longitudinally thereof, said foot rest extending outwardly from the spindle through a space between the base tubes, and a. springpressed latch member carried by the foot rest for selective engagement with the spindle sockets to l0 hold the foot rest in vertically adjusted position.
