Application March 24, 1948, Serial No. 16,752

2 Claims. (Cl. 15588) This invention relates to furniture, and more particularly to a childs seat adapted to be placed upon an adults chair, bench, or other horizontal surface, so as to increase the effective height thereof.

One object of this invention is to provide a seat of the above nature which includes means for adjusting its height, whereby the seat may be used to support children or other persons of different sizes at the desired level upon an adults chair for use at the dining table, the theater, or other places.

Another object is to provide a device of the above nature in which the adjusting means comprises a plurality of interfitting and interchangeable blocks adapted to be inserted between the top and base of the seat.

A further object is to provide a device of the above nature which will be simple in construction, inexpensive to manufacture, easy to install and manipulate, compact, ornamental in appearance, and very eiiicient and durable in use.

With these and other objects in view, there has been illustrated on the accom anying drawing one form in which the invention may conveniently be embodied in practice.

In the drawings,

Fig. 1 is a plan view of the improved childs seat.

Fig. 2 is a front elevation looking rearwardly from the line 22 of Fig. 1the seat member being shown in its lowest adjusted position.

Fig. 3 is a side elevation of the same, looking to the left from the line 33 of Fig. 1.

Fig. 4 is a front elevation similar to Fig. 2, but showing the seat member adjusted to a higher position.

Fig. 5 is a side elevation of the same, with the top seat member disengaged to show the shape of the end slots in the insert block.

Fig. 6 is a perspective View of the end of one of the insert blocks.

Fig. '7 is a perspective view showing the child's seat as it would appear when in position upon a chair.

Referring now to the drawings in which like reference numerals denote corresponding parts throughout the several views, the numeral I0 indicates a fiat base member of generally rectangular outline with rounded corners, and having a pair of elongated rectangular support blocks II, I2 on its upper surface adjacent its opposite side edges. The support blocks II, I2 are secured to the base member ID by a plurality of headed nails I3 each of which has a scratchpreventing rubber button Hi secured to the nailhead and located under the base member I0.

Provision is also made of a top seat member I5 having the same size and outline as the base member In and provided with a pair of depending rectangular side strips I6, I! which are secured to its undersurface by means of screws I8. The upper surface of the seat member I5 preferably has a rounded concavity I9 to enhance the comfort of the child using the seat.

The side strips I6, I! are each provided on both ends with pairs of spring clips 20, 2I whereby said side strips It, I! may be releasably secured to the support blocks II, I2 of the base member I in order to hold the seat-member I 5 in assembled relation with the base member Ill.

Each of the spring clips 20, 2| ispreferably formed from sheet metal and comprises a flat base portion 22 which is secured to the lower surface of one of the strips l8, IT by means of screws 23. Each clip 20, ZI also has a pair of depending side ears Mat opposite sides of the base portion 22 and a resilient end tongue portion 25 whi h is bent downwardly and inwardly, as shown.

The end surfaces of the support blocks II, I2 are each provided with a V-shaped slot 26 which forms an inclined surface ada ted to be engaged by one of the resilient tongues 25.'

Thus. it will be seen that the seat member IE will normally be retained upon the base member Ill, and the resilient characteristics of the tongues 25 will permit the member I5 to be readily disengaged from the base member ID whenever desired.

A plurality of spare insert blocks 21, 28, 29, 39 are provided for the purpose of adiusting the height of the seat. The end surfaces of the insert blocks 21, 28, 29, 30 are provided with V- shaped end slots 3| which have the same shape as the end slots 26 in the support block II, l2. A plurality of spring clips 32, which have the same form as the spring clips 28, 2 I, are secured one at each end of the lower surfaces of each of the spare insert blocks 21, 28, 29, 3!). It will thus be seen that any desired number of the spare insert blocks may be inserted and engaged between the support blocks II, I2 and the side strips I5, H in order to bring the. seat member I5 to the required elevation. When used in this manner, the spring clips 20, 2I, 32 will 00-- operate with the V-shaped end slots 26, 3I in the underlying blocks to hold the parts together.

3 At the same time, the side ears 24 of the clips 29, 2!, 32 will prevent the blocks from becoming displaced laterally.

It will be noted by reference to Fig. 2 that when the side strips Hi, I! of the top section l are assembled directly with the support blocks I l I2 of the base member It, a storage space 33 will be provided between said top section and base member which is of a suitable size to detachably contain the spare insert blocks 21, '28, '29, 30.

In order to secure these spare insert blocks in the space 33, provision is made of a pair of insert holding rails 34 which are adapted to frictionally receive the resilient flanges 25 of the spring clips 32. The insert-holding rails 34 include flathorizontal mounting flanges 35 which are secured to the upper surface of the basemember l0 adjacent the support blocks I i, I 2 by meansoi screws 36.

It will be understood that the seat may be made of any suitable material, such as wood, metal,

plastic, or fiber.

Operation In, operation, the seat may be placed upon a chair C, as shown in Fig. 7, so that a child sitting upon it will be elevated suitably at the dining table .or other location. If the child is very small it will be necessary to support him at a higher level, in which case the spare insert blocks '27, 28, 29, 30 may be used in order to raise the level of the seatmember [5, as shown in Fig. 4.

As the child grows older, one or more pairs of the insert blocks may be removed, so that a seat of the proper height for the child will always be available.

One advantage of the. improved childs seat is that it will do away with the necessity for a special high chair.

A further advantage is that the seat may be placed upon .any conventional household chair,

and inasmuch as it is very compact, it will 00- cupy less space than would be required for aspecial chair.

Another advantage is that the seat is entirely self-contained, and when the insert blocks are not required, they may be stored within the seat itself.

Another advantage is that the seat will avoid the old expedient of using books, pillows, etc. in order to raise the effective height of a chair so that it may be used by a child.

A further advantage is that the adjustable seat is easily portable, so that it may be carried to any desired location for use. Thus, the seat is not limited to use at the dining table, but may be taken to theaters, ball games, an other places where it may be used by a child to raise his eye level to such a point that he can see as well as other spectators.

While there has been disclosed in this specification one form in which the invention may be embodied, it is to be understood that this form is shown forthe purpose of illustration only, and that the invention is not to be limited to the specific disclosure, but may be modified and embodied in various other forms without departing from its spirit. In short, the invention includes allthe modifications and embodiments coming within the scope of' the following claims.

Having thus fully described the invention, what is claimed as new, and for which it is desired to secure Letters Patent, is:

1. In an adjustable seat, a base member, a pair of elongated horizontal support block elements fixed in spaced parallel relationship to the top thereof, a top seat member, and leaf spring clip means attached to the underside of said top seat member and engaged with holding means in the ends of said support block elements for detachably holding said base member and said top seat member interengaged.

2. The invention as defined in claim 1 wherein each of said leaf spring clip means comprises a horizontal base portion, a downwardly and inwardly directed tongue portion and vertical ears depending from the sides of the base portion for embracing the sides of said block elements, the holding means in said block elements being end notches receivingsaid tongue portions.
