1. Field of the Invention
The invention relates to children's activity toys, and more particularly to children's jumpers and free-standing jumpers.
2. Related Art
There are numerous children's activity devices that are useful to entertain and stimulate children while providing some level of gross motor development. Swings, jumpers, bouncers and other similar devices are designed to keep a child entertained and stimulated in a safe location. Some of these devices can be cumbersome, difficult to store, and may not be adjustable to children of different sizes.
Conventional jumpers can be attached to a frame or suspended from an available structure, such as a doorframe. Suspension jumpers that are attachable in doorways can impede movement of others through the doorway. Additionally, suitable doorframes are not always available or convenient. Moreover, such devices may be less secure than desirable for some caretakers.
Some jumpers with support frames can be difficult to transport, and can be difficult for parents to find a convenient place to store them when not in use. These jumpers can also be difficult or impossible to adjust to children of different sizes.
Thus, there is a need for a device that can be easily stored and moved. Also, a need exists for a jumper that is free-standing and easily adjustable with a stable base.
The invention includes a support frame having a first end frame portion with an apex, a second end frame portion having an apex and spaced laterally from the first frame portion, and a ground-engaging portion coupled to each of the end frame portions. The invention further includes resilient members configured to couple a seat to the frame, each running from the seat to a point below the apex on one of the end frame portions. The seat is suspended from the end frame portions.
In embodiments of the invention, the device can include height adjustment mechanisms, and a collapsible frame. The height adjustment mechanisms can adjust various components of the frame, resilient members and seat. The collapsible frame can collapse in several different ways.
These and other aspects of the invention will become apparent from the following drawings and description.
The invention is described with reference to the accompanying drawings. In the drawings, like reference numbers indicate similar elements.

Seats 110, 210 of each of the embodiments illustrated in
In each of the embodiments of the invention, the seat is spaced from the frame such that a child in the seat does not contact a frame member when positioned in the seat. Additionally, the frame has a sufficiently wide base (i.e., footprint) and the seat is attached to the frame such that the device or seat is difficult or impossible for the child to overturn.
One implementation of the device discussed above is now described with reference to
As shown in
Front base member 332 has a first end 332A and a second end 332B. First end 332A is slidably and adjustably coupled to first front mid member 342A through height adjustment mechanism 350A. Similarly, second end 332B is slidably and adjustably coupled to second front mid member 342B through height adjustment mechanism 350B. Rear base member 333 has a similar relationship with rear mid members 343A, 343B and height adjustment mechanisms 351A (not illustrated in
Front mid members 342A, 342B are pivotably coupled to front resilient member connectors 360A, 360B, respectively. Rear mid members 343A, 343B are fixedly coupled to rear resilient member connectors 361A, 361B, respectively. Resilient member connectors 360A, 360B, 361A, 361B are described in further detail below.
First top member 336A is coupled to resilient member connectors 360A, 361A, completing upright A-shaped portion 334A, with front portion 344A of first top member 336A being coupled to first front resilient member connector 360A and the rear portion 345A of first top member 336A being coupled to first rear resilient member connector 361A. Apex 338A is located at the top of first top member 336A, between and above resilient member connectors 360A, 361A. Similarly, second top member 336B is coupled to resilient member connectors 360B, 361B, with front portion 344B of second top member 336B being coupled to second front resilient member connector 360A and the rear portion 345B of second top member 336B being coupled to second rear resilient member connector 361B, with apex 338B located between and above resilient member connectors 360B, 361B.
Resilient members 370A, 370B, 371A, 371B are coupled to resilient member connectors 360A, 360B, 361A, 361B, respectively. The following description of resilient member 370B and its connection with resilient member connector 360B, as illustrated in
Upper attachment 378 of connection strap 372 and upper attachment 380 of cover 376 are wrapped and secured around front portion 344B of second top member 336B. Cover 376 covers connection strap 372 inside of resilient member connector 360B inside the resilient member connector 360B as well as outside of the connector 360B such that the cover 376 is not readily removable. The connection strap 372 and cover 376 extend through strap access aperture 382. Connection strap 372 is coupled to spring 374 at a location outside of the resilient member connector 360B.
Each remaining resilient member 370A, 371A, 371B is attached to its respective resilient member connector 360A, 361A, 361B in the same manner described above for resilient member 370B and resilient member connector 360B. The attachment of each of the resilient members 370A, 370B, 371A, 371B to infant support 310 is discussed below with reference to resilient member 370A.
As illustrated in
Referring again to
Front portion 344B of upper frame member 336B is fixedly coupled to resilient member connector 360B with fasteners 388. Second front mid member 342B is pivotably coupled to resilient member connector 360B at pin 390. Stops 392, 393 define a range of motion allowed by second front mid member 342B between the extended configuration and the collapsed configuration (represented by dashed lines in
Both release buttons 396A, 396B on resilient member connectors 360A, 360B must be released for frame 330 to move from the extended configuration to the collapsed configuration. Frame 330 can be held in the collapsed configuration with straps, an additional lock location for pins 394, a detent in the frame 300 or connectors or other similar locking devices.
Locking pin 352 engages an aperture in first rear mid member 343A and one of a plurality of apertures 354 in rear base member 333 to lock the device at a selected height. To release pin 352, release button 357A is pressed. Release button 357A pivots on hinge pin 358 to pull pin 352 away from aperture 354, thus allowing first rear mid member 343A to slide within rear base member 333. Pin 352 is biased by spring 359 in an engaged position. When pin 352 is released and the members 343A, 333 are slid with respect to each other to adjust the height, pin 352 automatically engages the next aperture 354 in rear base member 333. The adjustment range of first rear mid member 343A and rear base member 333 is limited by stops 355 in members 343A, 333 to prevent separation or over-engagement of member 343A, 333.
Each of the height adjustment mechanisms 350A, 350B, 351A, 351B is independently adjustable, but it is desirable for each adjustment mechanism to be set to the same height. When device 300 is in the collapsed configuration, height adjustment mechanisms 350A, 350B, 351A, 351B can also be adjusted to the shortest level to further collapse frame 330 for transport or storage.
Several different embodiments are illustrated in
While particular, illustrative embodiments of the invention have been described, numerous variations and modifications exist that would not depart from the scope of the invention. For example, although the height adjust mechanisms 350A, 350B, 351A, 351B are disclosed above as operating with mid members 342A, 342B, 343A, 343B fixedly attached to the height adjustment mechanism 350A, 350B, 351A, 351B and lower members 332, 333 slidably attached, in alternative embodiments, the lower members 332, 333 could be fixedly attached to one another, with mid members 342A, 342B, 343A, 343B being slidably attached.
Although frame configurations having one and two upright members and one to four resilient members are disclosed above, in alternative embodiments of the invention, several different numbers of upright members and resilient members, (e.g., three upright members with three resilient members, etc.), and alternatives to the illustrated frame configurations exist that do not depart from the scope of the invention.
Although the frame members discussed above are made of tube steel, other appropriate materials such as plastic can be used, and can have any cross-sectional configuration including solid members, square member, I-beam configurations or other shapes and configurations. Similarly hard plastic components such as the resilient member connectors, height adjustment mechanisms, tray, and feet, can be made from other suitable materials such as metal, stiff rubber, etc.
Although the embodiments above show various different frame adjustment/collapsing configurations, any of the features of any of the embodiments can be used with any other embodiment where appropriate (e.g., hinged frame of
Although height adjustment mechanisms and resilient member connectors are generally shown as separate components in the embodiments described above, a single component that adjusts the height of the frame and/or seat and collapses the frame can be used.
Although height adjustment mechanism 351A of the embodiment shown in
Although several alternatives for collapsing the frame are described above, various combinations in the number and position of hinges, sliding frame members, and other adjustment/collapsing members do not depart from the scope of the invention (e.g., additional pivot joints can be supplied in various locations on the frame).
Although the embodiments above do not specifically discuss electronics, different audio/visual devices and systems can be included. For example, tray 316, including toys 322, can include lights and audio output mechanisms that cause audio and visual feedback (e.g., colors, songs, sounds, etc.) Various actuators could also be employed to detect various movements of portions of a device according to the invention. Lights can be placed around tray 316 or on frame 330 that respond to a predetermined output or movement of infant support 310 with respect to frame 330. Similarly, a speaker can output a music or sounds in response to various inputs.
