The typical normal infant has the cognitive and neuromuscular attributes to transition from a sitting position to stand position starting on average around eight months to ten months of life. This is collaborated by the findings of Wells et al. entitled Biomechanics of Growth and Development in the Healthy Human Infant published in the Journal of the American Osteopathic Association, June 2002, Vol. 102, No. 6., stating, “By 9 months, 88% of the observed infants could sit and 69% could pull themselves up to a stand.”
From a biomechanical viewpoint, the sit to stand movement has a typically narrowed base of support that is reached by the horizontal transfer of the center of mass above the area defined by the feet and the connecting line of their outer margins. Muscle force generated by simultaneous trunk and knee flexion initiates a reaction force which enables the forward movement of the thighs followed by the seat clearance. The horizontal movement of the body changes into vertical defined as a continual movement of center of mass forward and upward. This is the moment when the feet become the base of support and is considered a key point in the successful transfer of the body weight from the seat base of support. There is a four-phase division of the sit to stand movement. The first phase (trunk flexion) is initiated with the first recognizable movement and ends just before rising. In the second phase (momentum transfer) the body continues the forward movement and maximal dorsal flexion in the ankle joint is reached. This initiates the beginning of the third phase (hip joint extension) which is completed with maximal extension in the hip joint. The fourth phase (movement stabilization), in which the angular velocity equals zero, completes the entire movement.
The sit to stand movement is considered a critical child development milestone. Motor or movement skills, such as sit to stand reflects a child's ability to control and direct voluntary muscle movement. Motor control develops from the top down and from central to peripheral muscles. Thus an infant will first hold his head up and much later walk. The degree of motor development is seen in stages of lying prone, head lifting, rolling over, sitting, crawling, standing and walking. Motor skills are indentified as either gross or fine. Gross motor skills involve the use or movement of large muscles in the body such as the arms, legs, or entire body. Fine motor skills involve the use or movement of small muscles in the body to accomplish small tasks such as grasping an object or play item between the thumb and forefinger commonly referred to as a pincer grasp which also develops hand to eye coordination. The significance of the specific accomplished milestones as defined by motor or movement skills; serve as markers of normal development and indicators of readiness for new physical and sensory challenges according to the American Academy of Pediatrics.
Unfortunately, many infants who have either cognitive and/or neuromuscular deficiencies due to premature birth, congenital health problems or for unknown reasons encounter developmental delays and reach milestones such as the sit to stand movement later than typical normal infants, if ever. Delayed development of motor skills can be associated with certain diseases and abnormal conditions.
Caregivers usually consult with their pediatricians who may recommend physical and developmental therapies in an effort to catch the infant up with same-age peers. Often the use of supports, devices and aides will assist the infant in overcoming their unique set of mental and/or physical challenges which can include Down syndrome, cerebral palsy, muscular dystrophy, and the like. As with Down syndrome, joint hypermobility syndrome is the main underlying factor why these particular infants are unable to obtain the necessary milestones in a timely manner. These developmental challenges include muscle weakness, difficulty learning motor skills, under-arousal of new activities, difficulty with attention and engagement and finally a tendency to avoid tasks that are demanding.
Another consideration why infants do not achieve age-appropriate milestones is the lack of interest by the infant to perform certain tasks or movements as well as sensory stimulation presented by the individual activity. It was long been accepted that infants as early as six months of age are fascinated by their reflection in the mirror. In fact, they devote a great deal of time and effort exploring their bodies and their image as suggested by Jacques Lacan's Mirror Stage. Infants are born with the perceptual means to discriminate themselves from other objects and people. Early on, they express an implicit sense of themselves as embodied, differentiated, situated and effective in the physical and social environment. This is the basis of the mirror self-recognition tests which remains a valid instrument to assess self-knowledge at a conceptual and re-cognitory level.
Conventional sit to stand devices (hereinafter “STS devices”) that are commercially available have numerous design shortcomings, especially with respect to the infant's initial attempts to develop the sit to stand movement as with respect to providing a way to continually attract and engage the infant. For example, the Jonti-Craft Cruiser Center and Coordination Mirror are designed for infants that have already mastered the sit to stand movement and are in the process of learning to walk or cruise which encompasses taking small steps while holding onto a wall or furniture for balance. These devices anticipate the infant is already in a first standing position and is developing a second walking motion commensurate with the walking milestone. Additionally, these devices appear to be either permanent or semi-permanent with no ability to be easily moveable or transportable.
Other items that are commercially available are activity tables and walkers manufactured by companies such as Fisher-Price®, LeapFrog® and VTech® are unable to retain an infant's attention due to the product's limited and static set of activities. Additionally, because of the various shapes and configurations, these products force the infant to move in an unsecured and unbalanced position thereby placing the infant into a greater probability of slipping off the product and falling, in turn, potentially causing serious injury to the infants head and spine. Furthermore, infants with mental and/or physical challenges will tend to avoid interacting and engaging with these products thereby continuing milestone setbacks and failures.
Therefore, there exists the need for a developmental device which facilitates the development of a child's cognitive and neuromuscular abilities so that the child may more readily attain a standing position from a first position such as laying, crawling or sitting and to remain standing for a period of time.
It is an object of the present invention to provide a child development STS device to support, assist and aide in an infant's movement from a sitting position to a standing position by engaging the infant with sensory stimulation to attract the infant to the device and then ensuring the infant will utilize the device to achieve the desired objective of standing.
It is a further object of the present invention to provide a child development STS device that incorporates a progressive series of fixtures preferably in a vertically upward plane whereby an infant moves upwardly to a standing position from a first position such as laying, crawling or sitting.
It is another object of the present invention to provide a child development STS device that is secured directly to a vertical supporting surface, such as a wall or door.
It is yet another object of the present invention to provide a child development STS device that is transportable, moveable and freestanding in a vertically upward position and temporarily secured to a horizontal supporting surface through the use of ballast, such as metal, water, sand or the like so that the device will be essentially immovable against the weight, movement and force applied by an infant.
It is a still further object of the present invention to provide a child development STS device that is pivotable to freely move from a first substantially horizontal position to a second substantially vertical position with or without predetermined angulations therein.
Yet another object of the present invention to provide a child development STS device that utilizes the infant's reflection through interchangeable reflective surfaces that are either temporarily or permanently affixed to the device which attracts and engages the infant with the device.
And still yet another object of the present invention to provide a child development STS device that utilizes play items either temporary or permanent which attracts and engages the infant with the device.
And still a further object of the present invention to provide a child development STS device that contributes to the development of both gross and fine motor or movement skills

The foregoing summary, as well as the following detailed description of the invention, will be better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, there are shown in the drawings embodiments which are presently preferred. It should be understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown.
In the drawings:
References will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings to refer to same or like parts.
The STS device 10 comprises one or more fixtures 12 with each fixture 12 permitting a child to grasp with his hand and raise his own body upwardly under his own ability. A fixture is any suitable object that is fixedly secured in place and capable of supporting a user of the device when held. The fixture 12 should be of a general shape and size to accommodate a child's hand so that the fixture 12 facilitates being readily grasped and/or held by a child 100 and to develop hand to eye coordination. In the embodiment shown in
The fixture 12 is secured to the side supports 14, on at least one edge is securely affixed either by mechanical or chemical fastening means, such as adhesives, rivets, stitching, welding, and the like. Preferably, the side support 14 is fabricated from the same material as the fixture 12, incompressible injection or vacuum molded thermoplastic resin or a wooden based material; however, it should be understood that the materials selected for the fixture 12, side supports 14, and other parts may be different. The terminal end of each fixture 12 should preferably not extend beyond the lateral outer edge of the side support 14 to avoid injury resulting in a child's impalement. In addition, fabricating a radius on each edge of each side support 14 preferably eliminates sharp right-angle corners wherever possible to avoid child injuries.
The fixture 12 is shown in
As shown in
Each fixture 12 is shown oriented parallel to the horizontal supporting surface 102 and vertical supporting surface 104 and is oriented perpendicular to the side supports 14. As described above, it should be understood that the fixtures 12 may be positioned in many orientations besides the horizontal orientation shown. The fixture 12 and side support 14 are securely fastened either temporarily, moveable, and positionable with suitable fasteners or permanently as in the case of unitary construction during the fabrication process. In its permanently secured configuration, each fixture 12 along the length of the side support 14 has a predetermined interval or spacing between each fixture 12. For example, a STS device 10 having an overall height of forty-eight inches may have its lowermost fixture 12 securely affixed at six inch above the surface 102 and a predetermined interval spacing requirement of six inches will contain eight fixtures.
In its temporarily secured configuration, each fixture 12 may be repositionable or slidable along the medial edge of side support 14, such as by the spaced holes 17 shown or the like, whereby each fixture 12 can be infinitely or selectively positioned with variable intervals between each fixture. Alternatively, a fixture 12 may be oriented in a horizontal, vertical, angled or a combination thereof in relationship to a supporting surface to achieve the stated goal of the STS device 10 which is the ability to stand.

Preferably, the STS device 10 contains ballast 20 (see
As shown in
These designs allow the STS device 10 to be transportable, movable and freestanding which permits a child to develop his sit to stand movement in virtually any indoor or outdoor environment, thereby further changing their source of entertainment while continuing to engage the child. These devices are pivotable to freely move from a first substantially parallel position relative to horizontal supporting surface 102 to a second substantially perpendicular position relative to the horizontal supporting surface 102, with or without, predetermined angulations which is accomplished by either an upper moveable hinge 46 or a lower moveable hinge 43. The ability to configure the STS device 10 at an angle less than perpendicular position relative to horizontal supporting surface 102 allows the child to engage at a decreased level of difficulty because the child's center of mass is at least partially over the STS device 10 as opposed to alongside of when the STS device 10 is in its substantially perpendicular position. From here to STS device 10 may be positioned to a more perpendicular angle. This progression continues until the child is able to reach a proscribed height when the STS device 10 is perpendicular to the horizontal supporting surface 102 and thereby achieve the position of standing.
Preferably, both the footplate 40 and the back brace 44 are fabricated from incompressible injection or vacuum molded thermoplastic resin or a wooden based material are designed to be hollow or cored out during the manufacturing process and can accept ballast 20 (see
Now referring to
In another embodiment and referring to
Referring to the integral connection, the stationary base 11 and cylindrical upright 16′ are independent of each other and thus permitted to rotate around each other. Preferably, these individual components are connected in a preselected fixed relationship and are temporarily secured through a mechanical or chemical fastener, such as a lock or pin to eliminate injury to a child who may potentially become unstable and possibly fall off the STS device 10′.
The cylindrical upright 16′ may be wrapped or coated in an interchangeably reflective surface 18′, such as Mylar® film, or the like either permanently secured with mechanical or chemical fasteners or temporarily removable with hook and loop fasteners. Alternatively, the reflective surface 18′ may be disposed on the inner wall of the cylindrical upright 16′ as shown. The reflective surface 18′ is designed such that a child will be attracted to and use the STS device 10′ to achieve the goal of developing the ability to stand. For example as the child becomes uninterested with a particular reflective surface 18′, it can be easily replaced with a more engaging reflective surface 18′ which will stimulate the child once again.
Once a child is engaged with the reflective surface 18′, he will become fascinated by his individual expressions and fluid movements which are uniquely his, always changing and a continual source of entertainment.
The STS device 10′ contains a series of spaced permanently secured pegs 12′ permitting a child the ability to perform the sit to stand movement either in a clockwise/counterclockwise manner or selecting pegs randomly. Additionally, as best seen in
The play items 24′ (see
The play items 24′ are arranged on the various pegs 12′, or cylindrical upright 16′ to encourage the child to reach to a first level whereby he is forced to transition his body in an vertically upward movement so that he can interact with the play items 24′ which is a desirable source of accomplishment while developing the child's pincer grasp as well as hand to eye coordination. As the child achieves a level, the play items 24′ are repositioned to the second level. This progression continues until the child is able to reach a proscribed height and thereby achieving the position of standing.

The fixture 12″ is secured to back support 16″, by at least one connection and is securely affixed by suitable fastening means, such as adhesives, rivets, stitching, welding, and the like. Preferably, the back support 16″ is fabricated from the same material as the fixture 12″, incompressible injection or vacuum molded thermoplastic resin or a wooden based material. It should be understood, however, that the materials selected for the fixture 12″, back support 16″, and other parts may be different. The back support 16″ may be secured either permanently or temporarily to any form of structure in an essentially horizontal plane or essentially vertical plane relative to the supporting surface.
The connection between the fixture 12″ and back support 16″ can be at any location along the length of the fixture 12″ such as the medial area or distal ends. Preferably, each free end of the fixture 12″ will have a radius edge and terminate into the back support 16″. Additionally, fixture 12″ will not extend beyond the back support 16″ to avoid injury resulting in a child's impalement. In addition, fabricating a radius on each edge of each side support 14″ preferably eliminates sharp right-angle corners wherever possible to avoid child injuries. Furthermore, the connection may either be permanently secure configuration with each fixture 12″ having predetermined interval spacing requirement or temporarily secured configuration with each fixture 12″ slidable along the medial edge of back support 16″ whereby each fixture 12″ can be infinitely or selectively changed with variable intervals between each fixture.
The STS device 10″ may also include an interchangeable reflective surface 18″, such as a safety glass mirror, a distorted mirror 22, etched mirror 23, reflective Mylar® film, or the like positioned behind the fixture 12″ affixed to the back support 16″ either permanently secured with mechanical or chemical fasteners or temporarily removable with hook and loop fasteners. The reflective surface 18″ is designed such that a child will be attracted to and use the STS device 10″ to achieve the goal of developing the ability to stand. As the child becomes uninterested with a particular reflective surface 18″, such as a safety glass mirror, it can be easily replaced with a more engaging reflective surface 18″, such as a distorted mirror 22 which will stimulate the child once again.
Once a child is engaged with the reflective surface 18″, he will be fascinated by his individual expressions and fluid movements which are uniquely his, always changing and a continual source of entertainment.
Additionally, the STS device 10″ may also include play items 24″, such as toys, stuffed animals or shapes which be attached to the fixtures 12″, back support 16″ or reflective surface 18″ either permanently secured with mechanical or chemical fasteners or temporarily removable with hook and loop fasteners so that a child will be attracted to and use the STS device 10″ to achieve the goal of developing the ability to stand. The play items 24″ are arranged on the various fixtures 12″, back support 16″ or reflective surface 18″ to encourage the child to reach to a first level whereby he is forced to transition his body in a vertically upward movement so that he can interact with the play items 24″ which is a desirable source of accomplishment while developing the child's pincer grasp as well as hand to eye coordination. As the child achieves a level, the play items 24″ are repositioned to the second level. This progression continues until the child is able to reach a proscribed height and thereby achieving the position of standing.

The fixture 12′″ is secured to any immovable surface either directly by mechanical or chemical fastening means, such as adhesives, rivets, stitching, welding, and the like or indirectly with one or more mounting brackets 30′″. The mounting brackets 30′″ are secured to the surface 104 via suitable fasteners 52. Preferably, the mounting bracket 30′″ is fabricated from the same material as the fixture 12′″, incompressible injection or vacuum molded thermoplastic resin or a wooden based material, however, it should be understood that the materials selected for the fixture 12′′, mounting bracket 30′″, and other parts may be different. The immovable surface may be any form of structure in a substantially horizontal plane or substantially vertical plane relative to the supporting surface.
The connection between the fixture 12′″ and mounting bracket 30′″ can be at any location along the length of the fixture 12′″ such as the medial area or distal ends. Preferably, each free end of the fixture 12′″ will have a radius edge and terminate into the mounting bracket 30′″. Additionally, fixture 12′″ will not extend beyond the mounting bracket 30′″ to avoid injury resulting in a child's impalement. In addition, fabricating a radius on each edge of each side support 14′″ preferably eliminates sharp right-angle corners wherever possible to avoid child injuries. Furthermore, the connection may either be permanently secure configuration with each fixture 12′″ having predetermined interval spacing requirement or temporarily secured configuration with each fixture 12′″ slidable or repositionable along the mounting bracket 30′″, such as by the spaced holes 17′″ shown or the like, whereby each fixture 12′″ can be infinitely or selectively changed with variable intervals between each fixture.
The STS device 10′″ may also include an interchangeable reflective surface 18′″, such as a safety glass mirror, a distorted mirror, etched mirror, reflective Mylar® film, or the like positioned behind the fixture 12′″ affixed to the immovable surface 104 either permanently secured with mechanical or chemical fasteners or temporarily removable with hook and loop fasteners. In the embodiment shown, the mounting brackets 30′″ are secured to the reflective surface 18′″ and the immovable surface 104 via the fasteners 52. The reflective surface 18′″ is designed such that a child will be attracted to and use the STS device 10′″ to achieve the goal of developing his ability to stand.
