Definitions

  • the present invention relates to a recreational device, and more particularly to a recreational device for children.
  • This apparatus comprises a pocket or bag having an upper open side and being provided in its substantially closed lower side with two openings through which a child resting in this bag can extend his or her legs.
  • This bag or pocket is secured to a contraction spring ⁇ and the upper end of the latter is in turn adapted to be secured to the frame of a door or the limb of a tree.
  • This known apparatus suffers from a variety of disadvantages. Firstly, it can be utilized only if a door with a suitable frame or a tree with a strong enough limb is available. Furthermore, it is cleavl that the height of the bag or pocket from the ground must be adjusted because the apparatus is to be used with children of different size and age as well as with door frames having different heights or with tree limbs which are located at different distances from the ground. Therefore, the upper end of the spring is not directly secured to the respective support that is the door frame or tree limb, but is connected thereto through the intermediary of a chain. This chain is adjustable in its length.
  • a recreational device which is adapted to be supported on a supporting surface and which comprises frame means having contact portions adapted to engage such supporting surface, and a mounting portion wrich is carried by the contact portions upwardly spaced from the supporting surface.
  • Resiliently expansible means is secured to and carried by this mounting portion, and support means is adapted to support a user thereon and is connected to and suspended from the resiliently expansible means in such a manner as to be capable of movement downwardly toward and upwardly away from the supporting surface in response to alternate expansion and contraction of the resiliently expansible means which in turn results from bobbing motions performed by a user whose weight is supported by the support means.
  • FIG. l is an elevational view of a device embodying my invention, certain components of the device having been omitted for clarity;
  • FIG. 4 is a view similar to FIG. 2 but illustrating another embodiment
  • FIG. l a recreational device comprising a frame wherein a plurality of elongated legs 2 are connected at their respective upper ends with an annular supporting or mounting member 1. It will be understood that there will be at least three such legs but in the embodiment of FIG. 1 it is assumed that the frame comprises four such legs with the one normally facing the front of the ligure having been omitted for the sake of clarity. Regardless of whether there are provided three or four of the legs 2, however, they will always be equi-angularly spaced about the annular mounting member 1.
  • each of the springs 5 is provided with a hook-shaped end portion 17 which is hooked into a suitable opening provided in one end of an elastomeric member 18 which is bent around the mounting member 1 and whose other end has an opening which permits penetration therethrough of one of the pins 15.
  • the elastomeric member 18 is connected to the mounting member 1 by extending one of the pins 15 through the opening provided for this purpose in the elastomeric member 18, and in turn one of the springs 5 is connected to the elastomeric member 18 by hooking the hook-shaped end portion 17 through another aperture provided in the elastomeric member 18.
  • the chain 7 is looped through this ring member 9 and is provided at its free end with a spring-latch hook 8, also known sometimes as acar bine hook, which can be engaged with any desired link of the chain 7 so that the length of the chain 7 can be varied simply by engaging the hook 8 with chain links which are closer to or farther downwardly spaced from the mounting member 1. It will of course be appreciated that it is also conceivable to eliminate the ring member 9 and to loop the chain 7 through the opening in the member 10 provided that such opening is dimensioned sufficiently large to permit this.
  • the foot is identified with reference numeral 3 and is assumed to consist of rubber or another elastomeric material having the illustrated part-spherical configuration.
  • a projcction provided on the foot 22 extends into the interior of the respective leg 2, which is either provided With a recess corresponding to the recess at the upper end or which is tubular throughout its entire length.
  • the projection 23 provided on the foot has an axial groove 24 in its outer circumferential surface and this groove communicates, as illustrated in FIG. 6 with a circumferential groove 25.
  • said couplings each comprise an axially extending passage in the respective leg member, and an axially projecting pin provided on said mounting portion and adapted to be received and frictionally retained in said passage.
  • each leg member is tubular and wherein said foot has a projection adapted to extend into the interior of said second end portion; and further comprising cooperating locking -portions provided on said projection and said second end portion and together constituting a bayonet lock for releasably connecting said foot to said second end portion.
  • said foot further comprises a spike portion provided on said projection and extending outwardly of said second end portion so as to penetrate into a supporting surface.
