TECHNOLOGICAL FIELD
[0001] The presently disclosed subject matter relates to infant chairs, in particular those
designed to bounce and/or otherwise move using the weight of the child therewithin.
BACKGROUND
[0002] Infant chairs are commonly used to place young children when they are awake. Such
chairs typically comprise a seat or a sling for supporting the child in a reclined
position, and may include means to provide a soothing movement, such as bouncing,
vibration, swinging, etc. Infant chairs may further comprise playthings or other activities
to occupy a child's attention when sitting/reclining therein.
SUMMARY
[0003] According to one aspect of the presently disclosed subject matter, there is provided
an infant chair having a seat portion carried by a support portion, the seat portion
comprising two connecting pins at a proximal end thereof received within the support
portion for connecting the seat portion thereto, the support pins being disposed above
a center of gravity of the seat portion and defining a substantially vertical swing
axis therebetween, the seat portion being configured to oscillate about the swing
axis.
[0004] The connecting pins may project downwardly from an upper portion of the seat portion.
[0005] The seat portion may be characterized by spring properties which facilitate oscillation
thereof about the swing axis when a distal end of the seat portion is displaced horizontally
from a rest position thereof, at least when carrying a child therewithin.
[0006] The seat portion may comprise a frame supporting a seat body. The frame may comprise
a hanger for hanging the seat body therefrom. The hanger may comprise a curved elongate
member. Ends of the elongate member may constitute the connecting pins. The elongate
member may comprise two or more subsections coupled to one another. The elongate member
may be made of a metal material.
[0007] The connecting pins may form an acute angle with the hanger.
[0008] The seat body may be made of an accommodating material.
[0009] The support portion may comprise a seat support configured for receiving therewithin
the support pins of the seat portion.
[0010] According to some examples, the support portion may comprise a base for resting on
a horizontal surface, the seat support portion being provided with an element separate
from the base. According to other examples, the support portion may comprise a base
for resting on a horizontal surface, the seat support portion being formed with the
base.
[0011] The support portion may comprise two bores having upwardly-disposed openings for
receiving therewithin the connecting pins. According to some examples, the bores may
be configured for rigidly maintaining the connecting pins therewithin. According to
other examples, the bores are configured for rotatably maintaining the connecting
pins therewithin. The infant chair may further comprise one or more bearings within
each bore for receipt therein of the connecting pins.
[0012] The seat portion may be configured to bounce when a distal end of the seat portion
is displaced vertically from a rest position thereof.
[0013] The infant chair may further comprise an arresting assembly configured to limit vertical
movement of the distal, free end of the seat portion.
[0014] The arresting assembly may span between the distal end of the seat portion and the
support portion.
[0015] The arresting assembly may be configured for detachable attachment to one or both
of the distal end and the support portion.
[0016] The arresting assembly may comprise two or more members longitudinally displaceable
with respect to one another.
[0017] The arresting assembly may comprise a damping element acting on at least one of the
members.
[0018] The arresting assembly may comprise a locking arrangement configured to selectively
prevent relative movement of the members.
[0019] The arresting assembly may comprise a bounce-limiting arrangement configured to selectively
define upper and lower limits of movement of the distal end of the seat portion.
[0020] The arresting assembly may comprise a strap spanning between the distal end of the
seat portion and the support portion. The strap may be configured for detachable attachment
to one or both of the distal end and the support portion.

DETAILED DESCRIPTION
[0022] As illustrated in Figs. 1 A and 1 B, there is provided a chair, which is generally
designated at 10, and which may be designed to bear and operate under the weight of
an infant or young child. The chair 10 comprises a support portion 12 carrying a seat
portion 14 disposed thereabove. It will be appreciated that herein the disclosure
and claims, terms relating to direction, such as "up," "down," "above," "below," etc.,
and similar/related terms are used with reference to the orientation in the accompanying
drawings based on a typical usage of the chair 10 and its constituent elements, unless
indicated otherwise or clear from context.
[0023] The seat portion 14 comprises a frame 16 (seen in Fig. 1 B) supporting a seat body
18 (seen in Fig. 1 A) in which the child may be laid. The seat body 18 may be made
of any suitable material, may have any desired rigidity (e.g., made of a rigid plastic
material, a flexible and/or accommodating material such as fabric, etc.), and/or may
be provided with one or more accessories, such as a safety strap 20.
[0024] The frame 16 comprises a hanger 22 (seen in Fig. 1 B), which may be of any suitable
shape, on which the seat body 18 is mounted, for example by hanging, being clipped,
etc., and two downwardly projecting support pins 24 (better seen, e.g., in Fig. 2).
The hanger 22 and support pins 24 are co-disposed giving rise to an acute angle therebetween,
i.e., when the support pins project downwardly in a substantially vertical orientation,
the hanger is oriented such that it slopes downwardly from top ends of the support
pins (i.e., the ends to which it is attached).
[0025] The frame 16 may be made of any suitable material, for example a metal, and is characterized
by spring properties (e.g., elasticity) such that, when a child is lying in the seat
body 18 and the seat portion 14 is pivoted with respect to the support portion 12,
the frame will, upon release, oscillate about its original position (i.e., its rest
or neutral position) in a manner which is soothing for the child. Accordingly, the
frame 16 may consist of a single suitably shaped element. According to some modifications
(not illustrated), the frame 16 may be assembled from two or more separate elements.
[0026] The support portion 12 is designed to rest on a floor or other horizontal surface
(herein, the term "floor" will be used to include any suitable horizontal surface).
Accordingly, it comprises a base, which generally indicated at 26, and a seat support
28. The base 26 is designed for resting directly on the floor, and may comprise a
plurality of horizontal members 30, e.g., attached to one another, or a single member
similarly formed, wherein bottom surfaces 32 thereof are generally coplanar, thereby
facilitating stable resting on the floor. It will be appreciated that wherein the
base 26 is described above with reference to Figs. 1 A and 1 B as comprising horizontal
members arranged along a path substantially below the seat portion 14, any suitable
base may be provided without departing from the scope of the presently disclosed subject
matter,
mutatis mutandis; e.g., the base may be formed as an arcuate member open away from the seat support
28, it may comprise several legs, etc. Another non-limiting example of the base 26
is illustrated in Figs. 4A and 4B.
[0027] The seat support 28 is connected to the base 26, and rises upwardly therefrom. It
may be formed separately from the base 26 and be assembled therewith, as illustrated
in Figs. 1A and 1B, or be formed integrally therewith. It comprises a lower end 34
configured for attaching to the base 26, and an upper end 36 (seen in Fig. 1 B) comprising
a seat mounting portion 38, configured for facilitating mounting of the seat portion
14 to the support portion 12. Depending on the construction of the base 26, the lower
end 34 may comprise two branches 40, each connected to one end of the base.
[0028] As best illustrated in Fig. 2, the seat mounting portion 38 may be formed as a separate
element from the rest of the seat support 28, such as within a plug 42, or integrally
formed therewith (not illustrated). The seat mounting portion 38 comprises two bores
44, each having a cross-section area sufficient to receive therein one of the support
pins 24 of the frame 16 of the seat portion 14 and permit free rotation therein, and
in each of which is received one of the support pins. Each of the bores 44 may terminate
in an upwardly-disposed opening 46 through which one of the support pins 24 is received
downwardly therethrough. One or more bearing 48, each configured to snuggly receiver
therein a support pin 24, may be received within each of the bores 44, thereby facilitating
the rotation of the support pin therewithin.
[0029] When the support pins 24 are so received within the bores, the hanger 22 of the frame
16, and thus the seat body 18, is carried such that its center of gravity is maintained
below the points of attachment thereof with the support portion, i.e., the support
pins within the bores 44.
[0030] Optionally, the bores 44 may be open at both ends, i.e., each further comprising
a downwardly-disposed opening 50, for example for accommodating therethrough a free
end of a support pin 24. The bores 44 may each be formed with sockets 52, i.e., portions
thereof having a cross-section which is larger than that of the rest of the bore,
each configured for receiving therein a bearing 48.
[0031] According to some examples, for example as illustrated in the accompanying drawings,
the bores 44 may be disposed substantially parallely to one another. According to
other examples (not illustrated), the bores 44 may be formed such that they are angled
with respect to one another, for example inwardly in an upward direction. The bores
44 may be formed such that they are substantially vertical, i.e., perpendicular with
the plane in which the bottom surfaces 32 of the base 26 lie, such that they are disposed
perpendicular with the floor when the chair 10 is resting thereupon.
[0032] In operation, a child (not illustrated) is laid in the seat body 18. The seat body
18 may be swung, for example by a caretaker, in a side-to-side motion, such as indicated
by arrow S in Figs. 1 A and 1 B. In order to effect such a motion, a caretaker pivots
the bottom free end of the seat portion 14 sideways in a direction indicated by arrow
S. As described above, the seat body 18 will, upon release, begin to oscillate, thereby
swinging from side-to-side. It will be appreciated that the side-to-side swinging
motion, is at least partially facilitated (for example in connection with the degree
of damping thereof) by the carrying of the seat portion 14 by the support portion
12 using a pair of support pins 24, each of which may rotate independently of the
other. It will be further appreciated that the swinging motion described above may
be about a swing axis, for example as indicated by
X in Fig. 1 B, which is spaced from of the support pins 24, e.g., disposed therebetween;
the frame 16 may be constructed such that the swing axis X is dynamic, i.e., moving
and/or pivoting over the course of the oscillation.
[0033] In addition, further owing to the spring properties of the frame, the seat body may
be bounced, for example by a caretaker or by force produced by a child within the
seat body 18 kicking, in an up-and-down motion, such as indicated by arrow
B in Figs. 1 A and 1 B. In order to effect such a motion, a caretaker pushes the bottom
free end of the seat portion 14 upward or downwards in a direction indicated by arrow
B. The seat body will, upon release, bounce up and down, e.g., about a bounce axis,
for example by
Y in Fig. 1 B, which is proximate to the uppermost parts of the support pins 24, i.e.,
where the frame 16 bends, thereby defining them.
[0034] The chair 10 may be provided with an optional arresting assembly 54. The arresting
assembly 54 may span between a free end (e.g., the lower end) of the frame 16 and
the base 26, thereby preventing swinging and/or bouncing of the seat body 18. As illustrated
in Fig. 4A, the arresting assembly 54 may comprise two telescoping members 56a, 56b.
A top end 58 of the arresting assembly 54 may be formed with a slot 60, e.g., to allow
selectively engagement/disengagement thereof with the frame 16. When engaged with
the frame 16 as illustrated, the arresting assembly 54 prevents swinging of the seat
body 18. The arresting assembly 54 may comprise any one or more of the following modifications:
- The arresting assembly 54 may comprise a damping element (not illustrated), for example
a spring within one of the telescoping members 56b, which is borne upon by the other
of the telescoping members 56a. Such a damping element may be useful, e.g., to mitigate
the weight of a heavy child within the seat body 18.
- The arresting assembly 54 may comprise a locking arrangement (not illustrated), configured
to selectively allow securing the position of the telescoping members 56a, 56b to
one another, i.e., preventing relative movement of the members, thereby arresting
the seat body at a position, preventing bouncing thereof. The locking arrangement
may facilitate arresting the seat body at one of several positions. It may also be
configured to be disengaged, thereby permitting free bouncing of the seat body 18,
for example as described above.
- The arresting assembly 54 may comprise a bounce-limiting arrangement (not illustrated),
configured to selectively define upper and lower limits of bouncing.
[0035] It will be appreciated that the arresting assembly 54 may be provided with any suitable
combination of, e.g., the above modifications,
mutatis mutandis.
[0036] As illustrated in Fig. 4B, the arresting assembly 54 may comprise a flexible strap,
looped, at a top end thereof, to the frame 16, and at a bottom end thereof to an eyelet
62 projecting from, or formed integrally with, the base 26. The bottom end of the
arresting assembly 54 may be provided with a closing means (not illustrated) such
as a snap, a hook and loop fastener such as is sold under the trade name Velcro™,
or any other suitable arrangement which allows selective engagement/disengagement
of the arresting assembly with the eyelet 62.
[0037] It will be appreciated that the arresting assembly 54 may be provided so as to be
assembled opposite to that illustrated in and described with reference to Figs. 4A
and 4B, i.e., with a top end thereof provided as per the description herein of the
bottom end, and a bottom end thereof provided as per the description herein of the
top end.
[0038] According to some modifications, the frame 16 may be provided such that the hanger
22 and support pins 24 give rise to an obtuse angle therebetween, i.e., when the support
pins project downwardly in a substantially vertical orientation, the hanger is oriented
such that it slopes upwardly from top ends of the support pins. The support portion
12 may be modified accordingly, e.g., such that the mounting portion 38 thereof is
disposed substantially lower than illustrated, for example close to the floor.
[0039] According to other modifications, the bores 44 may be formed such that they are not
perpendicular with the plane in which the bottom surfaces 32 of the base 26 lie, e.g.,
angled, in the upward direction, toward the seat portion 14.
[0040] According to further modifications, the bores 44 may receive the support pins 24
without bearings. For example, they may be formed so as to facilitate free rotation
of the support pins 24 therewithin without the use of bearings (e.g., by choice of
materials, using any other suitable element or elements configured to facilitate relative
rotation between the bores 44 and the support pins therewithin, etc.). According to
other examples, the support pins 24 may be fixedly received within the bores 44, e.g.,
wherein the side-to-side swinging motion of the seat portion 14 is facilitated by
elastic deformation of the frame 16, e.g., by twisting thereof, in particular at upper
portions of the support pins.
