Abstract
Description
[Technical Field]
[0001] 1. Background of the Invention The present invention relates to a high chair, and more particularly to a high chair having a removable guard, a removable footrest, a removable back and legs, which can be easily folded up for transport and storage purposes. [Background technology]
[0002] 2. Description of the Prior Art High chairs provide a safe space for small children to sit at the same height as others seated at the table. They must be constructed to high safety standards, be easy to use, and have a pleasing aesthetic design. Conventional high chairs generally have footrests that provide comfortable support for a child's feet. As a child grows, the fixed position of the footrest on a conventional high chair no longer accommodates the child's growing height. Fixed footrests are typically located in a mid-range position, which is too far away when the infant is small and too close when the infant is older, with an optimal position somewhere in between. Thus, an object of the present invention is to provide a high chair suitable for growing children. It is sometimes desirable to provide a table integrated into the high chair, suitable for use during meals and play. It is also an object of the present invention to provide a high chair with a table that is easily removable. It is sometimes desirable to provide a child seat with a removable back to make the seat easier to transport or move. Another object of the present invention is to provide a high chair that can be folded, thereby reducing storage volume. Summary of the Invention
[0003] The child chair 1 according to the present invention is A child chair having a seat 2 and four legs 3, the seat 2 having open front and rear back supports 24 and having sloping sides 26 extending forward from the supports and meeting a seat base 25, the seat base 25 being pivotally attached at each side thereof to a pair of first leg mounting sections 4 by a pair of seat pivots 6, each of the first leg mounting sections having sockets 5 in which the upper ends of a first pair of the four legs 3 respectively rest, each first leg mounting section 4 having a leg pivot 7 pivotally connected to a corresponding second leg mounting section 8 having sockets 9 in which the upper ends of a second pair of the four legs 3 rest, each leg extending outward and downward at an inclined angle, and each leg 3 having a foot 10 at its opposite lower end, each foot having an outer surface corresponding to the inclination angle of the leg, and the chair 1 being able to rest stably on a flat floor.
[0004] The seat pivot 6 according to the present invention has a releasable and lockable hinge that can be locked in an unfolded, i.e., extended, position and released to an unlocked, foldable position, allowing the seat 2 to be rotated relative to the leg attachment portion 4 and making it easier to store the child chair 1.

DETAILED DESCRIPTION OF THE INVENTION
[0007] Detailed Description Figure 1 is a perspective view of a high chair 1 according to one embodiment of the present invention. Chair 1 has a seat 2 and four legs 3. Seat 2 has open front and rear back supports 24 from which extend forwardly sloping sides 26 that meet at a seat base 25. Seat base 25 is pivotally attached to a pair of first leg attachment points by a pair of seat pivots 6 on each side.
[0008] Each first leg attachment part 4 has at its opposite end a socket 5 which locates against a knuckle portion of the seat pivot 6, with the upper ends of a first front pair of four legs 3 respectively mounted in each socket 5. Alternatively, the seat pivot 6 could be formed by a pin portion formed in the first leg attachment part and a knuckle formed in the seat 2. Each of the two front leg attachment parts 4 itself has a leg pivot 7 which pivotally connects to a corresponding second leg attachment part 8 by means of a pivot pin in the second leg attachment part 8 and a receiving bearing in the first leg attachment part 4. It will be apparent that the pin and bearing of the leg pivot 7 could simply be reversed.
[0009] The second leg mounting section 8 also has a socket 9 into which the upper ends of each of the second rear pairs of four legs 3 rest. In the unfolded position shown in Figure 1 (where the legs are unfolded and unfolded), each leg extends at an outward and downward angle, with a foot 10 at the opposite lower end of each leg 3. The angle of the foot corresponds to the angle of the legs in the unfolded position, so that the foot is stable on a flat floor.
[0010] The leg pivots 7 have releasable and locking hinges, the details of which are not shown as they would be apparent to one skilled in the art, that lock in a first, unfolded, extended position and are releasable to an unlocked, foldable position, allowing the first pair of legs to pivot relative to the second pair of legs, making storage of the chair 1 easier. The hinges have a locking folded position, making the chair easier to handle when stored.
[0011] Similarly, the seat pivot 6 has a releasable and locking hinge that locks in a first extended position and is releasable to an unlocked extended position, allowing the seat to pivot relative to the leg mounts 4, making it easier to stow the chair 1, as shown in Figure 7.
[0012] The second leg attachment section 8 is dog-legged and has an upper pivot section 11 at a predetermined angle relative to a socket section 12, so that the rear pair of legs are adjacent to the front pair of legs, making the chair more compact in the folded position. The angle between the pivot section 11 and the socket section 12 is approximately 110 degrees, but can be set between 90 degrees and 150 degrees.
[0013] 3-6, the illustrated detachable guard piece 23 has armrests 27, a front rail 28, and a center support 29. This is necessary to provide a safe seat for a small child to sit safely at the table at the same height as an adult seated at the table. A harness bracket 18 is provided for attaching a harness and keeping smaller children safe.
[0014] The present invention allows the use of the high chair 1 to support a newborn baby, allowing the newborn to sit at a table at the same height as the rest of the family. Conventional high chairs are only suitable for infants old enough to support their own weight by sitting independently, which generally occurs six months after birth, and none are suitable for babies under six months of age. Furthermore, the present invention allows a cradle, newborn frame, or bouncer frame, not shown in detail here, to be attached to the seat base 25 after removing the guide piece 29 and rear support 24.
[0015] 5, the guard piece 23 is removably attached to the seat 2 by a releasable attachment means 15. The attachment means is provided at the lower end of the central support 29 by a spring clip 15 so as to be removably or freely (lockable and unlockable) attached to a slot 17 in the seat base 25.
[0016] The guard piece 23 has a rear portion 13 which, together with the armrests 27 and front rail 28, forms a continuous torus which defines a hollow section 14 which fits over the rear back support 24 of the high chair 1 and securely fastens the guard piece 23 in place upon installation of the releasable attachment means. When a user places the rear portion 13 behind the rear back support 24, the spring clip 15 presses into the slot 17, securely locking the guard piece in place under tension. In addition to providing a smaller package for shipping, the center support 29 can be removed from the front rail 28 of the guard piece 23.
[0017] The front pair of legs also have receiving holes 38 for receiving mounting screws 39 for removably attaching the foot rest 35 .
[0018] The rear back support 23 can be removed from the seat base 25 by a removable back attachment means 19. The back attachment means comprises a spring clip 19 at the top of the rear back support which is engageable in a corresponding slot 20 in the side 26 of the seat 2.
[0019] The harness bracket 18 is removably attachable to the rear back support 23 .
[0020] Referring to Figure 9, as shown, the upper end of the leg 3 has a retaining hole 30 which receives a bolt 21 which passes through a hole 22 in the side wall of the socket 5, 9 and engages within the retaining hole 30 to secure the leg to the socket 5, 9.
[0021] Also shown in Figure 9 is a bracing strut 33 which extends between each leg of the second pair of legs 3 through a through hole 34 in each leg of the second pair of legs and is secured by a retaining bolt 31 held in a retaining hole in each distal end of the strut 33.
[0022] As shown in Figure 10, a foot rest 35 extends between each leg of the first pair of legs which is removably secured in place by a U-shaped retaining channel 36 secured to the inside surface of each leg of the first pair of legs. This foot rest 35 also serves as a support for the front legs.
[0023] Each U-shaped channel 36 has side walls 37 with openings 39 that correspond to spring-biased buttons 38 on the distal ends of the footrests 35 so that the buttons are biased to extend through the openings 39 and lock the footrests in place between the legs 3. The footrests can be removed by pressing the buttons 38 until they clear the openings 39 and each end of the footrest 35 clears (removes) the channels 36.
[0024] Those skilled in the art will readily recognize that the apparatus and method may be modified in various ways within the teachings of the present invention. [Explanation of symbols]
