The present subject matter relates generally to a portable rebounding apparatus. More specifically, the present invention relates to a rebounding device to be used against a stationary surface for generating a rebounding motion that includes a mechanism for adjusting the force of the rebounding motion.
Rocking is a familiar part of everyday human life. Numerous proven benefits of rocking have been established for centuries, while modern medicine has discovered new motivations and added reasons for rocking. One of the most well-known uses for rocking is to calm a baby. The gentle bouncing motion mimics the movement the baby felt inside the mother's womb and can soothe infants, aid in lulling children to sleep or while nursing, and reduce crying in colic episodes. Rhythmic motions also help build a better attachment bond between the parent and child, and aids in the growth of the newborn by stimulating both motor and sensory development.
Rocking for personal benefit is a safe activity and option for those that live an otherwise sedentary lifestyle or for people with limited physical motion, including many aging adults, individuals suffering with injuries or chronic ailments, or those seated for long periods of time. The act of rocking has proven benefits such as the easing of arthritis and back pain, improved muscle tone, improved balance, and increased circulation. Studies have shown that patients with Alzheimer's disease that rock regularly demonstrate a significant improvement in depression, anxiety, balance, and a decrease in pain medication usage.
Studies have revealed that rocking causes an increase in psychological well-being for those suffering from dementia, anxiety, and depression due to released endorphins that elevate the mood. Additional studies suggest benefits of rocking can provide comfort and add to the positive treatment of anxiety, attention deficit disorder, attention deficit hyperactivity disorder (ADHD), and autism. For example, studies of patients with ADHD show that rocking movement such as intensity and frequency is correlated with accuracy on cognitively demanding tasks requiring sufficient attention. Studies have also shown that vestibular rehabilitation therapy such as rocking can help patients with vestibular dysfunction, such as vertigo and episodes of dizziness. Rocking may also be a low-energy movement to increase blood flow for those experiencing physical restrictions, such as elderly and those with limited mobility or physical disabilities. Health experts recommend some form of motion to increase circulation and muscle movement when sitting or laying for extended periods. Rocking has also been shown to help people fall asleep faster and improve memory consolidation with more time spent in non-REM sleep.
Rocking can also improve pain management by calming the parasympathetic nervous system. It also improves cognitive processing by soothing the brain and facilitating concentration with the ability to think logically.
However, prolonged rocking in a seated position cannot be performed comfortably without an external device such as a rocking chair to assist in repeating the motion for even a short period of time, let alone hours on end. A continuous rocking motion for long durations without assistance also creates significant strain on muscles and joints. Existing solutions are extremely limited in their embodiments, versatility, and flexibility of use. The operating conditions and other utility requirements often prohibit users from being able to use existing apparatuses when and where rocking assistance is needed most. The use of conventional rocking furniture is limiting in that it cannot easily be moved from room to room or accompany the user during travel.
Further, conventional rocking solutions require a large amount of floor space and are therefore not suitable for use in small rooms and can be difficult to store when not in use. While some hospitals and nurseries equip parents, staff, and caregivers with rockers or gliders, providing a rocker or glider in each room is expensive, which becomes problematic for facilities operating with a limited budget. Smaller options for rocking infants include bassinets, bouncers, or cradles, but in these options the infant is separated from the caregiver, limiting the ability to simultaneously hold, nurse, or easily feed the infant while rocking.
Still further, conventional rocking solutions cannot be combined with other existing furniture such as a sofa or bed, thus preventing users from utilizing such furniture when needing to hold and nurse or calm an infant with rocking. Many mothers prefer to nurse while sitting in an upright position in bed, especially at night, but must choose between the comfort of a bed and the functionality of rocking furniture because nothing exists to allow both simultaneously.
Conventional rocking solutions also present the problem in lacking adaptability to the user of the furniture. For example, a rocking chair may be perfectly comfortable for adult use but may be too strenuous for an elderly person, a person recovering from surgery, a person with limited mobility, a person with physical challenges, etc. The force needed to generate full backwards and forward cycle on a rocker or glider may be easily provided by the leaning back of a larger, heavier body, whereas smaller framed persons, those with pre-existing conditions, and/or aging individuals may need to repeatedly push off the ground using their legs in order to generate motion. With conventional rocking chairs and gliders it can be difficult to achieve partial rock cycles or more subtle motion when the user or child may prefer gentle rebounding rhythm. The size, shape, and condition of the user's body and the personal preference of the user impacts the amount or size of the force needed when utilizing rocking furniture, and a conventional piece of rocking furniture fails to accommodate the variety of needs of multiple users.
Finally, conventional rocking solutions are not adjustable to accommodate various users having different sizes, shapes, and rocking needs. For example, a glider moves in response to the amount of force applied, and a smaller person with less weight may not be able to generate a sufficient rocking force while a larger person with a greater weight may have no problems generating a rocking force. An elderly person may need to generate a rocking motion with even less weight. Therefore one rocking device may not able to provide the appropriate amount of rocking force to a variety of body types and builds.
Accordingly, there is a need for a portable, compressible rebounding device for generating a rocking motion while in a seated position that is adjustable to accommodate the needs of different users, as described herein.
To meet the needs described above and others, the present disclosure provides a rebounding device that includes an adjustable spring mechanism to accommodate the needs of users having different sizes, shapes, and needs. The rebounding device described herein includes a front member and a rear member with a spring mechanism provided therebetween, the spring mechanism including a force adjustment assembly. During use, the user positions the rear member of the rebounding device against a stationary object such as a chair or a wall. The user rests his back against the front member and applies pressure to generate a gentle rocking motion. The rebounding device exerts a biasing force when compressed that gently propels the user's upper body forward while maintaining a seated position. The biasing force is determined in part by the setting of the adjustable mechanism.
In one embodiment, the rebounding device includes a front member, a rear member, and a spring mechanism positioned between the front and rear members. The spring mechanism includes first and second elongate spring elements, each spring element including front and rear planar surfaces integral with a rounded portion. Each spring element operates as a leaf spring with the front and rear planar surfaces moving toward and away from one another about the rounded portion.
Each of the front planar surfaces of each spring element is twisted inwardly toward the rear planar surfaces so as create a curvature for receiving the user's back. The front member is secured to the front planar surfaces of the spring elements and includes a curvature that complements the curvature of the front planar surfaces. The rear member is secured to the rear planar surfaces of the spring element. During use, the user's back rests comfortably against the curved front member and the angled front planar surfaces while the rear member and the rear planar portions rest against the stationary surface.
The force adjustment assembly includes a third spring element that operates as a leaf spring with front and rear planar surfaces moving toward and away from one another, similar to the first and second spring elements. The third spring element moves vertically along the height of the rear member between a lowermost position adjacent to the rounded portions of the first and second spring elements and an uppermost position distal from the rounded portions of the first and second spring elements. The adjustable mechanism includes a guide track secured to an inner surface of the front member and an screw housing mounted on an inner surface of the back member. The guide track on the front member receives the front planar surface of the third spring element during use.
Adjustment is provided by moving the rear planar surface of the third spring element along the length of the screw housing. More specifically, a threaded block is secured to the rear planar surface of the spring element and includes an inner portion that is positioned within and moves along a longitudinal channel of the screw housing. The threaded block may be secured to the rear planar surface via screws or other attachment mechanisms, or may be formed integrally with the spring element.
A drive screw extends through a screw housing cover that is mounted to the screw housing, and extends through a bore in the screw housing cover so that a shaft of the drive screw extends into the channel. The drive screw is secured in place through bearings at opposing ends of the screw. The user can rotate the screw within the channel of the screw housing by rotating a knob attached to an upper end of the drive screw outside of the screw housing.
Within the channel, the shaft of the drive screw extends through a threaded bore within the threaded block such that rotation of drive screw causes the threaded block to move verticalling within the channel. The user manually turns the knob secured to the drive screw to adjust the positioning of the threaded block within the channel, in turn moving the rear planar surface of the third threaded element vertically along the channel as well.
The positioning of the spring element of the force adjustment assembly modifies the rebounding or biasing force provided by the rebounding device. For example, in one example embodiment, the first and second spring elements alone provide a rebounding force of about 25 and 30 lbs. The addition of the third spring element of the adjustable mechanism increases the rebounding force to between 30 and 60 lbs, depending on the positioning of the third spring element of the force adjustment assembly. In other embodiments, the spring mechanism 106 may provide a smaller or greater minimum, maximum, and/or range of rebounding force with and without the force adjustment assembly.
Referring to the embodiment illustrated herein, when the third spring element of the adjustable mechanism is positioned in a lowermost position adjacent to the rounded portions of the first and second spring elements, the added rebounding force is minimal. As the third spring element is gradually moved up to the uppermost position, the amount of additional rebounding force gradually increases. The user can adjust the biasing force using small incremental changes to increase or decrease the pounds of biasing force provided by the device. When the third spring element of the adjustable mechanism is positioned in an uppermost position distal from the rounded portions of the first and second spring elements, the added rebounding force is at a maximum. The device may provide a biasing force that falls within the range of about 30 and 60 lbs, and the adjustable mechanism enables the user to select the precise force appropriate for the specific size, shape, and condition of the body using the device.
In one embodiment, the front and rear members include a front and rear flexible material extending between the pairs of front and rear planar surfaces, respectively, of the first and second spring elements. The front and rear flexible materials are tightly stretched between the front and rear pairs of the front planar portions and the rear planar portions, respectively, of the first and second members so that pressure applied to the material causes the front planar portions to move toward the respective rear planar portions. A foam padding or other thick material may be secured to each of the front and rear members and/or flexible material.
An object of the invention is to provide a solution for adjusting the strength of a bouncing motion provided by a rebounding device, maintaining a smooth bouncing motion throughout the range of strength available.
Another object of the invention is to provide a solution to render a single rebounding device usable for a number of people having different shapes, sizes, and rebounding motion needs.
A further advantage of the invention is that it enables a single rebounding device available for use in a wide variety of settings, from childcare to elder care, etc.
An advantage of the invention is that it provides a portable rebounding device that is easily carried from one location to another, takes up little space, and can be easily stored away when not in use.
Another advantage of the invention is that it can be utilized with almost any existing furniture or supporting surface; thereby allowing the user to rock continuously while holding the infant while sitting wherever they have a supporting surface deemed comfortable.
A further advantage of the invention is that it provides a solution to a need for a rocking motion that is significantly less expensive than conventional rocking solutions.

In one embodiment, each elongate spring element 110, 112 may have a width W that ranges between about 1.5 in. and about 2.5 in., although the width may vary as desired and may vary throughout the length L. Each spring element 110, 112 may also have a thickness T that ranges between about 0.125 in. and about 0.25 in., created by a single layer or multiple, stacked layers. In the illustrated embodiment, the width W and thickness T of the spring elements 110, 112 vary along the length L, having smaller values at the rounded portions 110e, 112e than at the front and rear ends 110b, 112b. In other embodiments, the width W and thicknesses T of the spring elements 110, 112 vary based on manufacturing processes and/or as desired.
The first and second spring elements 110, 112 may be comprised of any material that provides sufficient elasticity to enable repeated rebounding motions while being sufficiently strong to structurally support a person's weight. Example metallic materials include aluminum, an aluminum alloy preferably but not necessarily having a T6 temper, such as 6061T6, steel, and a steel alloy such as AISI 5160. The device may also be made of plastic such as polyvinyl chloride, a carbon fiber composite material, or a wood material.

The rounded portion 116e of the third spring element 116 functions as an additional spring leaf mechanism that provides additional rebounding force to the rebounding force provided by the first and second spring elements 110, 112. This positioning of the third spring element 116 modifies the strength or biasing force of the rebounding device 100 by adding to the force applied by the first and second spring elements 110, 112.
The rounded portion 116e may include a reinforcing spring element 117 secured thereto. The reinforcing spring element 117 has a length that extends along the rounded portion 116e of the spring element 116. In one embodiment, the reinforcing spring element 117 is welded or otherwise secured to the rounded portion 116e.
In one embodiment, the first and second spring elements 110, 112 alone provide a rebounding force of about 27 and 30 lbs. The addition of the third spring element 116 of the force adjustment assembly 114 increases the rebounding force to between 30 and 60 lbs when the third spring element 116 is in the lowermost and uppermost positions, respectively.
When the third spring element 116 is positioned in the lowermost position, the rebounding device 100 operates primarily using the first and second spring elements 110, 112 only because a significant amount of force is needed to engage the third spring element 116. With the central axis CL2 of the rounded portion 116e of the third spring element 116 aligned with the central axis CL1 of the rounded portions 110e, 112e of the first and second spring elements 110, 112, the third spring element 116 is most difficult to reach. A minimal amount of additional rebounding force is provided at this positioning.
As the third spring element 116 is gradually moved up to the uppermost position, the amount of additional rebounding force gradually increases. When the third spring element 116 is in the uppermost position, a maximum amount of additional rebounding force is provided. When the central axis CL2 of the rounded portion 116e of the third spring element 116 is at the greatest offset from the central axis CL1 of the rounded portions 110e, 112e of the first and second spring elements 110, 112, the rounded portion 116e of the third spring element 116 can provide the maximum among of additional rebounding force.
The user can adjust the biasing force using small incremental changes to increase or decrease the pounds of biasing force provided by the force adjustment assembly 114. The force adjustment assembly 114 enables the user to select the precise force appropriate for the specific size, shape, and condition of the body using the device.
In other embodiments, the spring mechanism 106 may include first and second adjustability mechanisms on the first and second spring elements 110, 112 with or without the addition of the force adjustment assembly 114. Each of the first and second spring elements may comprise, for example, an adjustable torsion spring with a preloaded setting attached to a rotatable knob. In some embodiments, the adjustable torsion spring is secured to the elongate element 110, 112 through a frame mounted thereto. In other embodiments, the adjustable torsion spring is provided in lieu of the elongate element 110, 112 and secured to the front and rear members 102, 104.

A drive screw 124 is positioned within the bore 122a and extends into the longitudinal channel 118a as shown in
As shown in
The external portion 132b is positioned outside of the longitudinal channel 118a of the screw housing 118. The external portion 132b is formed integrally with the internal portion 132a such that the external portion 132b also moves with the internal portion 132a as it moves along the drive screw 124. The external portion 132b provides a planar surface 132d onto which the rear end portion 116b of the third spring element 116 is attached. The rear planar surface 116d of the third spring element 116 may be secured to the threaded block 132 via screws an adhesive, or other attachment mechanism, or may be formed integrally with the third spring element 116. Rotation of the drive screw 124 causes the threaded block 132 to move vertically along the screw housing 118, which in turn causes the third spring element 116 to move vertically along the screw housing 118.
As shown in the embodiment illustrated in
During use, the user positions the rear surface 104 of the device 100 against a stationary object such as a chair, wall, tree, etc. as shown in
A foam pad, a rubber material such natural latex, or other thick, cushioning material may be secured to the front member 102 or the flexible material and may optionally be encapsulated within the outer housing material 107 as shown in
In other embodiments, the components of the rebounding device 100 may be formed integrally. For example, the front member 102, the rear member 104, and the first and second spring elements 110, 112 may be formed integrally. In one embodiment, the rebounding device 100 may be comprised of a metal such as an aluminum alloy, that is stamped, laser cut, water-jetted, or otherwise cut from a sheet of the material and pressed into formation. In other embodiments, the rebounding device 100 may comprise a wooden material shaped into formation. In still further embodiments, the rebounding device 100 may be a polyvinyl chloride material that is that is molded, such as injection molded, into formation. The material and method of manufacture may vary based on the manufacturing process or as desired.
In still further embodiments, the spring mechanism 106 may be modified to include one or more reinforcing spring elements that provide additional elasticity and/or strength to account for heavier users. The number, position, and location of reinforcing elements may vary as desired or, in some embodiments, based on the user's preference. In some embodiments, the reinforcing spring elements added to the first, second, and third spring elements 110, 112, 116 and/or to any part of the spring mechanism 106 may be adjustable.
For example, reinforcing spring elements like the reinforcing spring element 117 described above with reference to the third spring element 116 may be secured to the rounded portions 110e, 112e of the first and second spring elements 110, 112. Each reinforcing spring element has a length that extends along the rounded portion 110e, 112e of the spring element 110, 112. In one embodiment, the reinforcing spring elements are welded or otherwise secured to the respective rounded portion 110e, 112e. In other embodiments, the reinforcing spring elements may be snapped into place or otherwise added only if desired.
In other embodiments, a reinforcing spring element may be secured along the inner surface of the rounded portions 110e, 112e of the first and second spring elements 110, 112. Such reinforcing spring elements may be attached to the first and second spring elements 110, 112 through a frame component, the reinforcing element being positioned along but not secured to the inner surface of the rounded portions 110e, 112e, 116e. The frame may include components connected to the front member 102, the rear member 104, and/or the spring elements 110, 112, 116.
In still further embodiments, the reinforcing element comprises a torsion spring that may be adjusted. In still further embodiments, the reinforcing spring element may include one or more torsion springs, one or more leaf springs or a Z-shaped spring that is secured to the inner surface 104a of the rear member 104 between the spring elements 110, 112. In this embodiment, leaf springs may be secured to the inner surface 104a of the rear member 104 and provide resistance against the front member 102 only when a significant amount of pressure is applied by a user to the front member 102 during use.
In other embodiments, one or more reinforcing spring elements are added to one or more of the following locations: inside or outside of the rounded portion 110e, 112e of the spring elements 110, 112, between the front and rear planar surfaces 110c, 112c and 110d, 112d of each spring element 110, 112, and between the front and rear members 102, 104. The use of reinforcing spring element(s) enables the rebounding device 100 to be used by a heavier person and to increase the life of the spring elements 110, 112. The ability to optionally add and/or adjust reinforcing spring elements also enables the rebounding device to be purchased for a single home and used for people of various sizes.
In still further embodiments, the rebounding device 100 may include first and second rubber guards that extend along the rounded portions 110e, 112e of the spring members 110, 112. The rubber guards may include treaded portions that prevent the rebounding device 100 from slipping on the floor, the seat of a chair, or other surface during use.
The rebounding device 100 may also include first and second structural members that, when in use, support the rebounding device to be used on its own without being positioned against a structural support such as the back of a chair or a wall. In one embodiment, the first and second structural members are hingedly attached to the rear planar portions 116a, 116b of the first and second spring members 108a, 108b, respectively, so that they rotate between an open position and a closed position. In the closed position, the structural members are secured to the rear planar portions 116, allowing the rebounding device 100 to be used against a structural surface such as a chair, a wall, or the like, as described above. When the structural members are in the open position, they extend away from the rear planar portions 110d, 112d so that the rear planar portions 110d, 112d form an acute angle with the surface on which the rebounding device 100 is positioned. The user can then lean against the rebounding device 100, creating the rocking motion without the need for a piece of furniture or other structural support.
The dimensions of the rebounding device 100 may be modified in order to tailor the device to a specific use. For example, the width of the first and second spring elements 110, 112 of the rebounding device 100 may be wider than illustrated herein in order to accommodate for usage with a wheelchair or a hospital bed.
As described above, the rebounding device can be used in a variety of applications, from rocking an infant to sleep to the comfort and benefit for those with conditions such as dementia, anxiety, and autism. It should be noted that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the spirit and scope of the present invention and without diminishing its attendant advantages.
