3,490,808 HOLDING DEVICE FOR HIGHCHAIR TRAYS Max Siege], Los Angeles, Calif., assignor to Babyhne Furniture Corp., Los Angeles, Calif., a corporation of California 7 Filed May 8, 1968, Ser. No. 733,733 Int. Cl. A47b 83/02 US. Cl. 297153 7 Claims ABSTRACT OF THE DISCLOSURE Holding devices are disclosed for use in holding a tray upon the arms of a highchair. Each such device includes an elongated channel-shaped bracket having a base, opposed parallel sides extending from a surface of the base and open ends. Stabilizing means are formed integrally with the channel so as to extend from the ends of said base outwardly and in the same direction as the sides extend from the channel. Plunger means are movable mounted on one of the sides so as to extend into the channel. Two of these devices are used on a highchair tray. The highchair arms may be inserted into the brackets on these devices on a tray by withdrawing the plunger means on them and locating the arms within the brackets. Then, the tray may be locked in place by allowing the plunger means to extend into the channel.

BACKGROUND OF THE INVENTION The term highchair is normally utilized to designate .chairs for comparatively small children or infants. Normally such chairs include or are used with a tray for feeding and play purposes. Such a highchair normally has a seat located at a greater height than a normal chair seat and arms extending from the chair back above the seat along its sides to the front of the chair. When a tray is used with such a chair the tray normally extends across the extremities of the arms remote from the seat back in such a position as to effectively tend to hold an infant or small child in position in the chair.

Such trays have been mounted upon or secured to highchairs in a number of different manners. It has been known to secure such trays in place through the use of auxiliary arms pivotally connected to the seat back. With this type of construction it was possible to pivot the tray between an operative position extending between the chair arms and an inoperative position permitting access to an infant in the chair. This type of construction is disadvantageous inasmuch as it requires a comparatively large amount of room to move the tray between the two positions indicated and inasmuch as with this type of construction it is comparatively easy for the infant in a chair to be hurt as the tray is being moved between its positions.

As a result of this type of factor, various specialized types of tray attachment devices have been developed which have been used to directly secure or attach a tray in place upon a highchair. It is considered unnecessary to discuss in detail in this specification the most common of these various other different type of devices. Frequently they have been formed of metal so as to utilize a number of different parts such as pivot pins enabling the tray to be moved from an inoperative to an operative position, various different latch means and the like. Structures of these various different types have been disadvantageous for a variety of different reasons.

Those of these devices that have been relatively complex have also been relatively costly. In the juvenile furniture industry, comparatively small cost differentials frequently make the difference between commercial failure and commercial success. Also comparatively complex holding devices for use in attaching a tray to a chair are normally somewhat difficult to clean when cleaning is necessary. There is another important factor, however. Small children in highchairs tend to move and push around the trays used in conjunction with such chairs. When the mounting or holding devices used with these trays are metal and the chair itself has metal arms the results of such activity by children can be noisy and disturbing.

SUMMARY OF THE INVENTION An object of the present invention is to provide new and improved holding devices for use in holding a tray upon the arms of a highchair which overcome various disadvantages and limitations of prior related devices as are briefly indicated in the preceding. A related object of the invention is to provide complete highchairs utilizing the holding devices of this invention so as to eliminate problems attendant to the use of prior related devices as are indicated in the preceding discussion. Further objects of this invention are to provide new and improved holding devices for the intended utilization which are relatively simple, are relatively easy to clean, are capable of giving prolonged, effective service and are inexpensive, and which when used effectively preclude a great deal of the noise resulting from the rattling of a tray by a child or infant.

The various objectives of this invention are achieved by providing holding devices, each of which includes an elongated, channel-shaped bracket having a base, opposed parallel sides extending from the same surface of the base and open ends. This bracket preferably includes as an integral part of the bracket stabilizing means attached to the ends of the base so as to extend outwardly from the ends of the base and so as to extend in the same direction from the base as the sides. The channel and the stablizing means are preferably formed integrally of a non-metallic, resilient material, capable of absorbing vibrations so as to prevent unnecessary noise when the holding devices are utilized on a highchair. Each of these holding devices also includes a plunger means attached to one of the sides of the bracket so as to be capable of being moved in order to lock the holding device with respect to the arm of a highchair.

DESCRIPTION OF THE DRAWING The actual details of the invention as well as other objects and advantages of it will be apparent from a careful consideration of the remainder of this specification and the accompanying drawing in which:

FIG. 1 is a partial side-elevational view of a highchair used with a tray held in place in accordance with this invention;

FIG. 2 is a partial cross-sectional view taken at line 2-2 of FIG. 1;

FIG. 3 is a bottom plan view taken looking upwardly from the bottom of FIG. 2; and

FIG. 4 is a partial cross-sectional view taken at line 4-4 of FIG. 2.

The drawing is primarily intended so as to clearly illustrate for explanatory purposes a presently-preferred embodiment or form of this invention. Those skilled in this art of the design and construction of juvenile furniture will realize that changes may be made in the structure illustrated through the use or exercise of routing engineering skill without departing from the spirit and scope of this invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT In FIG. 1 of the drawing there is shown a part of a highchair having legs 12, a seat bottom 14, a seat back 16, and arms 18. The arms 18 extend parallel to the seat bottom 14 from the seat back 16 to adjacent to the front of the chair 10. The chair 10 illustrated and described in this manner is not intended to represent any particular highchair inasmuch as the present invention is applicable to any style or construction of highchair having the various elements of such a chair described herein.

The chair 10 is utilized with a tray 20 which may also be of any desired construction. Thus, this tray 20 may be metal or plastic. The particular tray 20 illustrated has a dished out top surface 22 separated from vertically extending sides 24 by rolled edges 26. Bottom mounting and reinforcing brackets 28 are secured to the sides 24 in the tray 20 in order to help make the tray 20 rigid and to provide mounting sites for two identical holding devices 30 in accordance with this invention. Preferably two of these holding devices 30 are used so as to support the tray 20 by fitting over and engaging the arms 18 of the chair 10. If desired a single bracket corresponding to the brackets 28 can be used for mounting purposes with the two holding devices 30 employed or these devices can be mounted directly on a tray, such as the tray 20.

Each of the holding devices 30 includes an elongated channel-shaped bracket 32 having a base 34 and opposed, parallel sides 36 and 38. These sides 36 and 38 may be shaped the same, but in order to save material may be made of different shapes which do not exactly conform, but which are adapted to achieve an efiicient holding action with respect to an arm 18. As will be seen from FIG. 2 the bracket 32 is dimensioned so that the sides 36 and 38 and the base 34 fit around and engage three sides of an arm 18.

In the construction shown, the side 36 is located generally in the center portion of the base 34 and the side 38 has two extended lobes 40 located toward the end of the base 34. This is intended so that the bracket 32 will engage an arm 18 at three space points along the length of this arm to secure an efficient holding action. Preferably the sides 36 and 38 have rounded corners in order to prevent their catching something when the tray 20 is being located upon and moved from the chair 10.

Each of the holding devices 30 includes as an integral part of the bracket 32 loop-like resilient arms 42. These arms 42 extend from the ends 44 of the base 34 downwardly from this base a short distance in the same direction as the sides 36 and 38 extend from the base 34. These arms 42 also extend away from the base 34 outwardly from the ends 44 so that in eiTect they are positioned at a diagonal with respect to the base.

Preferably the entire bracket 32 is formed of a resilient, self-supporting non-metallic material such as any of a variety of now commonly known polymers possessing the properties of being somewhat resilient or spring-like and still being self-supporting in character. A particular suitable material or type of material for use in forming the bracket 32 is a common injection molding grade of socalled nylon polymer. This material is particularly suitable since it is capable of internally absorbing vibrations. When the bracket 32 is formed of such material the individual arms 42 in effect act like resilient springs and hence may be referred to as spring means.

This type of action of the arms 42 is quite important when the individual holding devices 30 are used on an arm such as the arm 18. In effect these arms 42 act like stabilizers, resiliently engaging an arm 18 so as to tend to balance a tray such as a tray 20 in a desired operative position in such a manner that it is difficult for a child to rattle such a tray with respect to a chair such as the chair 10. The arms 42 are sufficiently flexible, however, so as to permit an arm 18 to be inserted into the bracket 32 to a desired depth with a minimum of difficulty.

A holding device 30 used preferably is attached to one of the brackets 28 through the use of simple screws 46 in dished-out portions 48 in the base 34. These screws are located in this manner so that they cannot be contacted by the arms 18.

A plunger 50 is located on the side 36 of each holding device 30 at a position in which when a holding device 30 is located upon an arm 18 of a chair 10 the plunger 50 on it can hit within a hole 52 in such an arm. With the construction shown the plunger 50 extends through a stepped hole 54 in a mounting housing 56 attached to a side 36 and is secured in place by means of a small knob-like handle 58.

The plunger 50 shown is preferably also stepped so that a coil spring 60 may be located around it within the housing 56 under compression. With this type of structure the spring 60 in a holding device 30 biases the plunger 50 outwardly from the side 36 into the space adjacent to the base 34 so that the tray 20 will automatically be locked into place by engagement of the hole 52 when the handle 58 is released.

It will be realized by those skilled in the art that the holding devices 30 are rather simple effective devices which may be inexpensively manufactured. It will be further realized by such individuals that these devices are of such a character that they can be cleaned when required. They will also realize that these devices can be easily and conveniently used. Moreover, they will realize also that these holding devices 30 are advantageous inasmuch as they effectively serve to prevent noise from tray rattling or the like.
