Rocking horse suspension system

Abstract

A rocking horse has a stand that includes a base portion with four tubular columns. The columns each have a tubular wall defining an interior. The wall has a top end with a top rim defining a top opening to the interior. An anchor pin extends through the wall and into the interior so that the pin engages two separated locations on the tubular wall. An S-shaped hook has a first end directly attached to the pin within the interior of the tubular wall and a second end extending out of the top opening on each column. The rocking horse also has four resilient members with outer ends connected to the second ends of the hooks, and inner ends connected to the toy horse for suspending the toy horse from the columns.

Description

BACKGROUND

The present invention is generally related to children's riding toys, and more particularly, to a suspension system for a rocking horse or other riding toy.

Toy rocking horses typically have a stand with a vertical member at each one of the four corners of the stand. Helical or coil springs typically extend from the tops of the vertical members to a toy horse suspended by the springs in the middle of the stand. With this configuration, when a child is sitting on the horse, the springs permit the horse to be rocked back and forth and bounced up and down.

An example of a typical rocking horse is presented in U.S. Pat. No. 3,155,390 to Moore et al. The Moore et al. '390 patent discloses a rocking or hobby horse featuring a pair of transverse, horizontal rods that pass through and support the toy horse's body. Coil springs are connected between the ends of the horizontal rods and four tubular, generally vertical members positioned one each at the four corners of a stand. Each coil spring has a hook formed on its outer end that passes through a hole formed in the tubular wall of the corresponding vertical member. Significant wear of the hole and coil spring hook may occur with such an arrangement, however, which significantly limits the durability of the product.

U.S. Pat. No. 2,891,792 to Thoeming discloses a rocking horse having a stand that also features tubular, generally vertical members at each corner. A pair of horizontally-aligned holes are formed through the top portion of each vertical member. A ring with two hook-like terminal ends that engage the holes is positioned on the top of each vertical member. Each ring is engaged by a hook formed on the outer end of a corresponding coil spring where the four coil springs cooperate to suspend the horse from the stand. While the arrangement of the Thoeming '792 patent performs well, it is difficult to assemble and also suffers from durability concerns.

A more complex design for a rocking horse is disclosed by U.S. Pat. No. 5,645,489 to Laiche et al. The rocking horse of the Laiche et al. '489 patent features a stand that has a tubular, generally vertical member at each corner. Each tubular member receives a specially designed connector with flanges that engage a projection formed on the interior of the tubular member. An eye-bolt has a stem secured to the connector so that the loop portion of the eye bolt extends out of the end of the tubular member. A coil spring is hooked to the loop portion of the eye-bolt so that the toy horse is cooperatively supported by the springs. Ribbed sleeves fit over the coil springs and upper portions of the tubular members. While the rocking horse of the Laiche et al. '489 patent performs well, the spring connection arrangement is somewhat complicated which leads to increased production costs.

SUMMARY OF THE INVENTION

The present invention is directed to an easily assembled and durable rocking horse suspension system. More specifically, a rocking horse has a toy horse adapted for being sat upon by a child and a stand that includes four columns. Each column has a tubular wall defining an interior. The tubular wall has a top end with a top rim defining a top opening to the interior. An anchor pin extends through the wall and into the interior. The pin engages two separated locations on the tubular wall. An S-shaped hook has a first end attached to the pin within the interior of the tubular wall and a second end extending out of the top opening on each column. The rocking horse also has four resilient members, which are preferably coil springs, with outer ends connected to the second ends of the S-shaped hooks and inner ends connected to the toy horse. As a result, the toy horse is suspended from the columns. Sleeves are positioned over each resilient member and cover a portion of each column.

The following detailed description of embodiments of the invention, taken in conjunction with the appended claims and accompanying drawings, provide a more complete understanding of the nature and scope of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown in FIG. 1, a rocking horse 10 constructed in accordance with the present invention features a toy horse 12 suspended on a stand, indicated in general at 14. More specifically, the toy horse 12 is connected to the stand by four resilient members 16a-d, which are preferably coil springs. While a toy horse is described below and illustrated in the figures, it is to be understood that the invention may be used with other types of suspended riding toys.

The stand 14 has four generally vertical members or columns, indicated in general at 18a-d in FIG. 1. Each column 18a-d features a tubular wall 20a-d. Each tubular wall 20a-d respectively has a bottom end 22a-d connected to feet or base portions 24a-d of the stand 14.

As illustrated in FIG. 1, a pair of transverse, horizontal bars 21 and 23 extend through the body of the toy horse and, as described below, support the toy horse on the stand 14. As illustrated in FIG. 2 for resilient member 16a, each resilient member 16a-d of FIG. 1 has an inner end connected to a corresponding D-shaped ring 17. In FIG. 2, D-shaped ring 17 is attached to the end portion of bar 19 via a bore 25 that is formed through the bar.

As shown in FIG. 1, the outer ends of the resilient members 16a-d are connected one each to the top ends 26a-d of the columns 18a-d. As shown in FIGS. 3 and 4 the tubular wall 20a of column 18a defines an interior 28. Interior 28 is accessible through a top, main opening 30, which is defined by a top rim 32 on the top end of wall 20a. The wall 20a features two opposing sidewall holes 34, 36. While only the details of the top of column 18a are shown in FIGS. 3 and 4, the remaining columns 18b-d are the same.

As illustrated in FIGS. 3 and 4, an anchor pin 38, such as a screw or other fastener, is placed through the sidewall holes 34, 36 so that a head 40 of the pin 38 is disposed on the exterior of one of the sidewall holes. While the illustrated anchor pin 38 is threaded directly to the sidewall holes 34 and/or 36, a nut (not shown) could optionally be used to secure the anchor pin to the wall 20a. Alternatively, a pin having no threading at all or a variety of other known fastening devices may be used.

An S-shaped hook 44, as illustrated in FIGS. 3 and 4, has one end 46 secured to the pin 38 within the interior 28 of the wall 20a. The other end 48 of the hook 44 extends out of the top opening 30 for attachment to a J-hook 50 (FIG. 4) on the corresponding resilient member 16a. As shown in FIG. 4, a substantial portion of the end 48 of hook 44 extends out of the end of wall 20a, but it will be appreciated that no limit exists as to how much of hook 44 needs to extend out of column 18a and past top rim 32. More specifically, the amount that hook 44 extends of out of the end of wall 20a will depend on the angle and design of the top end of column 18a. The same may be said, of course, for columns 18b-d.

As shown in FIG. 1, sleeves 52a-d preferably cover the tops of columns 18a-d as well as resilient members 16a-d. The sleeves 52a-d are made of a plastic, rubber or other flexible material to accommodate the motion of the resilient members without cracking, ripping or breaking.

To assemble the connections at the tops of columns 18a-d, the sleeves 52a-d are initially positioned over the resilient members 16a-d or columns 18a-d and slid out of the way. Then, as illustrated in FIGS. 3 and 4 for column 18a, the S-shaped hook 44 is held within the tubular wall 20a to align the lower portion 46 of the hook 44 with the sidewall holes 34, 36. Next, the anchor pin 38 is placed through one sidewall hole 34 or 36, the lower portion of S-shaped hook 44 and finally through the opposite sidewall hole 36 or 34. The assembler then engages portion 48 of S-shaped hook 44 with the J-hook 50 of the resilient member 16a so that it is secured to S-shaped hook 44, and thus column 18a. Sleeve 52a is then slid over the connection. The procedure is repeated for columns 18b-d.

While some of the embodiments of the invention have been shown and described, it will be apparent to those skilled in the art that changes and modifications may be made therein without departing from the spirit of the invention, the scope of which is defined by the appended claims.
