The present invention relates primarily to a child walking safety product.
Today, older first-time parents are very common. Many women have their first child after 40 years of age. About 25% of all women in California have their first birth at an age over 35. This trend is seen all over the world. Many men at the age of 50-65 are fathering new babies. Many elderly people, such as grandparents, are childcare givers to their grandchildren. As soon as a small baby becomes mobile, such as crawling, standing, cruising and walking, the parents or attendants can expect a lot of work. Very often a small baby will trip and fall while learning to stand or walk. At those times, an older parent will have a very difficult time bending over, as many have by then experienced back injuries, back pain, or knee pain before having a child. Back pain and tiredness are common complaints by parents during the period when their children learn to walk.
Normal infants learn to walk as early as 6-7 months and as late as 14-16 months. During this period of time, a caregiver spends between 30 min per day to 3-4 hours per day assisting the baby with walking. Due to the significant height difference between a small child and his or her attendant, it is natural for the attendant to bend forward the upper-body to reach a small child with both arms and hands. Thus, this small child's arms or under arms are held by the attendant's hands. In other words, to be able to reach a small child, the attendant bends her/his back to hold the small child's arms when the child stands or walks. This is an extremely difficult position for many people, especially for an older person, a tall person or a person who has back problems. More importantly, when the child's arms are held by the attendant, the infant's arms and hands cannot move freely and naturally, so that the child is not able to touch, grasp, or play with objects as he or she desires. Also, the attendant's both hands are not free in this back bending position. Accidentally, many small children's arms or shoulders have been injured or twisted from sudden lifting or pulling because their attendants could not coordinate with the baby's movement.
Obviously, keeping a baby's hands free during walking exercise is very important in many ways: 1) it allows the baby to have good coordination between the body and hands, so that the baby can be in a natural physical position as much as possible during practicing walk; 2) most important, it helps to stimulate small babies brain development because it provides a great opportunity for a baby to receive information through hands. As we know, the learning process at this age relies mostly on hand touching. During the first three years of an infant's development, the brain develops most significantly in mass and in establishing synapses. It would be a great opportunity to receive a large amount of stimulations if a baby can go any place where a grown-up goes, such as walking into elevators, climbing up stairs, and walking on grass, pavement, shores of lakes or rivers, or anywhere. The more information a baby obtains, the more synapses can be developed, and the more intelligent a baby can become, and the earlier a baby can become independent. Learning how to step as well as obtaining information through this process will stimulate the child's brain development, which benefits both motor functions as well as intellectual development. Generally, due to safety concerns, most parents will not bring their babies to many places until their children reach a certain age. This present invention will provide a useful device to help save a lot of physical effort, avoid emotional stress and ease the burden of parenting. It helps stimulate small babies during the early development stage and explore the world safely.
The earliest infant-walking aid invention was made as early as 1913. U.S. However, effective baby walking aids for training a small baby to walk are still lacking in the market. For example, U.S. Pat. No. 1,193,374 granted in 1916, discloses a walking harness. This harness uses two parallel straps to surround the wearer's upper body. The hand-holding straps are narrowed straps that form a loop structure by connecting the ends. The harness is attached to the center back of the wearer. This design is very similar to most baby walking safety harnesses on the market today. The harness is normally operated by a single hand. The harness may be useful for keeping a toddler or older child nearby, but it is not a proper device to train a small baby to walk. When a baby is lifted at the center of the back, the baby can easily become out of balance and falls.
U.S. Pat. No. 1,749,999 helps an adult assist a small baby to learn how to walk. It was developed as a garment-like apparatus that is worn by a baby. Two straps extend from the back of the shoulder to be held by a caregiver's hands. There are many disadvantages in this prior art device: the hand straps are very narrow straps that provide no protection to the wearer. When the straps are pulled, the front anterior part of the apparatus could be pulled up toward the wearer's neck, and may become a choking hazard. No buckles were available at that time, and it seems difficult to put on or take off this apparatus. The wearer can become very hot when used during the summer.
U.S. Pat. No. 5,120,287 discloses a system in which two solid wood bars are provided for the caregiver and the baby to hold onto. The baby has to use his/her hands to hold onto the wooden bars, and therefore does not get his/her hands free. This prior art reference discloses a strap system used to hold on the baby's bottom, which does not seem to be convenient for a small baby when a baby starts to walk. It is always important for a baby that there is no obstacle below the waist and no other obstacle stretching between the legs. In addition, the solid rigid bar system is not as convenient as foldable clothes for storage and transportation.
The most recent U.S. Pat. No. 6,836,902, discloses a design similar to the design described in the U.S. Pat. No. 1,749,999, but adding a seat part for holding the wearer's bottom. The tensions at the baby's bottom and legs create an unnatural force by the infant when the harness is in use. Plus, this suit-like garment limits the time that it can be used. It may work for smaller or younger babies, and definitely not good for a larger or older babies. The hand leashes are thin, offer no protection and provide less control to the wearers. A baby wearing such a harness is like a baby in a suit or in a net. It may be too hot for a baby to use during summer and is not easy to put on or remove.
Baby walkers help a baby learn to walk. A baby walker has a seat and wheels that allow a baby to sit inside surrounded by a frame. The wheels allow a baby to walk around. For example, U.S. Pat. No. 3,778,052 shows a wheeled support structure. After baby walkers become popular several years ago, many babies fell from the stairs in these walkers and became seriously injured. Now, these wheeled walkers are considered dangerous for infants and have been taken off the market. In addition, even before they are able to walk independently, many small babies have strong desire to walk and play in the playground like the big kids do. They also desire to experience with their attendants in going into elevators, on stairs, through doors, and on pavement or grass. However, all of these wheeled devices for assisting a baby walk cannot fulfill these needs.
Currently, there are many types of baby safety walking harnesses in the market, which are intended for toddlers who are able to walk already. They are used as restraining devices for keeping the kids nearby and to avoid being lost in the crowd or on the street. Most of the walking harnesses are made from webbing straps and have a long leash attached on the center back; some are designed to attach to the both sides of under-arms. They are not designed or cannot be used to assist an infant to learn how to walk.
This present invention provides a baby safety walking apparatus which is carried by a baby and held by an attendant. It is designed to secure and support activities of infants during their early stages of development, such as crawling, standing, or walking. It prevents trips and falls and gives confidence to the infants. It is mostly designed to help the attendant to release back strain and reduce the physical and emotional stresses when giving care to a small child. This baby walker/walking safety belt apparatus comprise a major body part and four additional strap systems:
With these designs, this baby walking safety apparatus has a fashionable appearance, and is simple and versatile. The functions of this present invention include the following:
Before an infant is able to stand or walk on its own, the posture of an infant walking looks like an ox pulling a wagon. The babies' weights are mostly on their bodies. They tend to use their upper bodies to pull the legs because their legs are not strong enough to support their bodies in an upright position. Therefore, the small baby can fall out of the balance very easily. As we can see, infants normally keep a semi-vertical position while walking by slightly bending their upper bodies forward. To help an infant maintain his or her balance, the effective supporting area is at the upper front torso. Because adults and small babies have significantly different heights, the adult human's arms are not long enough to reach a baby's arms without bending the back or bending the knees. Naturally, every childcare attendant has to bend his or her upper body to grasp the baby's arm or hands when a small child is learning to stand or walk. As soon as a human bending the body forwardly, a pressure or strain is generated on the human's back. It is extremely painful to the people who have back injuries. It is painful and unpleasant for everyone because it is not a natural relaxing human physical posture. Thus, to help adults assist small children to stand/walk safely and comfortably, a novel device is made here that can meet all of these challenges. This present invention is a significant improvement over the prior arts.
This apparatus is a symmetrical structure, preferably made from any kind of fabrics or other material with soft, durable and flexible natures, such as leather or plastic as the exterior portion. The padding-materials are preferably polyesters, but should not exclude any other soft, durable and flexible materials. The soft flexible feature of these materials offers this apparatus for holding, carrying and lifting the baby from any direction or angle. This apparatus has multiple usages, such as holding a baby onto a chair, or any other seat structures. The wideness and padded feature makes this apparatus strong, secure and easy to be used for pulling, lifting, and swinging a child without causing any discomforts.
The major body part of this apparatus comprises a center portion as the front bib. It translates from the front to just behind the armpits of the wearer, and functions as the supporting element for the upper torso. This center portion comprises a first surface and a second surface, with the first surface having an exterior surface and an interior surface. Similarly, the second surface has an exterior surface and an interior surface. The first surface interior surface is opposite to the second surface interior surface, with padding materials inserted between the opposite surfaces. The best description of its shape is an inverted top portion of a hand-fan with narrowing ends. The important features of this center portion are: i) a wide and big middle portion; ii) gradually curving up ends from the center, the top edge being less curved and the bottom edge being more curved, and also iii) gradually narrowing down ends from the center, terminating with narrower ends. Since the attendant is significantly taller than the wearer, the pulling force comes from up from a slight vertical position, which is neither horizontal nor vertical. The shape of the center portion allows the connection with the extended elements in a perfect position to meet this consideration. The features above are essential to allow a) the center portion to fit naturally with the infant upper torso curve; and b) the pressure to be evenly diffused over a large area of the body without having any discomfort. The prior art baby walking safety harnesses use webbing straps. Even though some products used the padded feature, they are still too narrow to secure an infant when carrying or lifting an infant with 20-30 pounds of body weight. Plus, the body weight lands on the infant's front chest are not diffused in an efficient area and can cause extremely discomfort for a small child.
Two elements that extend the attendant's arms are designed as a pair of wings. They are referred to as extended elements. The extended elements attach to the center portion in symmetrical positions at both ends, giving this major body part of baby walking safety belt apparatus a semicircular shape. Similar to the center portion, each extended element comprises a first surface (outer side) and a second surface (inner side) where each surface has an exterior surface and an interior surface. A padding material is inserted between these interior portions. The shape of the extended elements looks like a dragon-fly's wing. The fixed end has the same width as the center portion's ends. The anterior edge is preferably straight, and the posterior is curved, gradually widening up from the fixed end to the free end, forming a wing shape like a dragon-fly's. When it is pulled, the extended element naturally slide up-right toward the attendant's front body from the wearer's back, like two human arms. They are wide and well-padded, providing good protection and a strong lift to the wearer, controlling the balance of the child when s/he is in any motion. In contrast, the prior art baby walking harnesses use webbing straps as a leash held by the attendant hands, providing no protection to the wearers. Thus, the body portion of the apparatus of the present invention assists infant to walk and extends the attendant's arms.
Two shoulder straps can be carried on the wearer's shoulder separately. They are used to secure the apparatus on the wearer's body. Each shoulder strap has two ends. The first end is preferably affixed on the center top of the center portion. The second end preferably passes through a D-ring which is affixed permanently on the extended element second surface (inner side) exterior surface adjacent to the center portion. Two shoulder straps are attached with a latching portion of a center buckle on the second ends. When it is in use, two straps are connected with each other from opposite direction and form a closed circle that translates from front to the back of the shoulder. Each latching part of the center buckle is designed to slide on the strap it is attached to, so that each shoulder strap is adjustable.
A body strap is a single long strap with a first end and a second end that encircles a wearer's body by a fastening assembly. It is used to secure the apparatus on the wearer's body. The first end is separated from the second end by passing through a tunnel-like structure, which is designed as a body strap holder patching on the inner side of the center portion. This tunnel-like structure has an exterior surface and interior surface. The interior surface is opposite to the exterior surface of the second surface of the center portion. It is a long narrowed rectangular shape with a width that a body strap can pass through without any difficulty. The length is always shorter than that of the center portion. This way, it can secure better to a smaller child. The ends of the body strap float out from each left or right opening and each connects to a center buckle latching portion. When the body strap is in use, the center buckle is latched on the wearer's back so that the center portion is securely attached on the wearer's body like a garment. The body strap can also secure a baby on a chair or a seat structure serves as a safety belt. By using a center buckle, the body strap is adjustable at both ends.
A hand grasp area is provided at the free end of the extended element that allows the attendant's hands to grasp onto the apparatus. A loop-shaped structure designed as a hand-holder provides a means of securing the attendant's hand without loosening grip on the apparatus. When the apparatus is in use, the attendant's hands passes through the loop and allow the loop to rest on the attendant's wrist, so that the attendant can grasp the extended elements fully.
An additional structure connecting to a hand-holder is a tail-like locking strap. A hand-holder and a locking strap are generated from a single strap by simply folding one end facing down toward the middle point and leaving the other end free like a tail. The middle point is attached to the outer side of each extended element, so either strap system can be positioned in the free end of each extended element. Thus, a hand-holder and a locking strap extend to opposite directions along the center line that parallels the extended element. Each tail-like locking strap is attached with a fastening portion of a center buckle. With a fastening assembly, the locking straps provide a means of connecting the free ends of the extended elements. This allows the extended elements to form a closed circle that is used to secure a baby on a chair, to be held by a hand or that rests on the attendant's shoulder.
When this apparatus is in use, both the shoulder straps and the body strap are latched together on the wearer's back. These two strap systems provide a double securing system that protects the wearer's back when the extended elements are pulled from the wearer's front. By using these two strap securing systems, this apparatus becomes a garment-like structure that securely surrounds the wearer's upper torso, and is able to withstand the force from any direction without becoming loose. While carrying, lifting, swing, or pulling the wearer, this apparatus provides a strong support and a secure area between the wearer and the attendant. The apparatus can function as a lifting carrier for easily moving a baby from one spot to the other spot.
When it is not in use, the apparatus can be kept on the wearer's back when babies are crawling, standing, walking or sitting. Its appearance looks like a decorative costume for a small child. The floating ends of the extended elements can be lifted up and folded over and crossed on the wearer's back; they are secured by the connecting shoulder straps. These two extended elements look like a pair of butterfly wings or a pair of angel wings freely floating on the wearer's back.
The advantages of this present invention over all other prior art are as following:
This invention provides a portable device for use by one holding an infant in any motion without back bending. It is used to train an infant walk. Referring now to the drawings, wherein similar parts of the invention are identified by like reference numerals. The baby walker/walking safety belt apparatus (17) as seen from the front side view in
