DETAILED DESCRIPTION OF EMBODIMENTS
As illustrated in FIG. 1, there is provided an infant activity apparatus generally designated 1, comprising a first arch 10 and a second arch 30, first and second coupling arrangements 50a, 50b (hereafter, the coupling arrangement may be referred to collectively using reference numeral 50) defining therebetween a primary axis X, a pair of mounting arrangements 70, and a plurality of decorative elements 90.
The first arch 10 spans between a first end 12a and a second end 12b. The second arch 30 spans between a first end 32a and a second end 32b thereof. The respective first ends 12a, 32a of the arches 10, 30 are pivotally articulated to the first coupling arrangement 50a, and the respective second ends 12b, 32b of the arches are pivotally articulated to the second coupling arrangement 50b. 
As seen in FIG. 2, each of the ends 12a, 32a and 12b and 32b (only the first ends 12a, 32a are illustrated in FIG. 2) are generally ring shaped about the primary axis X (not illustrated in FIG. 2). An interior side of each is formed with a socket 20 containing therewithin an arresting pin 21, the purpose of which will be described hereinbelow. The interior sides are each formed with inner and outer circular panels 22, 23, defining a space 24 therebetween. Two stoppers 25 are provided traversing the space 24 between the two panels 22, 23 of each of the ends 12a, 32a and 12b and 32b. The outer panels 23 each define a seat 26 for the coupling arrangement 50, as will be described below. Each of the panels 22 is formed with an opening 27, through which the arresting pins 21 protrude.
Reverting to FIG. 1, each of the coupling arrangements 50 comprises a pivot hub 51 and a fastener element 53. As illustrated in FIG. 3A, the pivot hub 51 has a round cross-section formed about the primary axis X (not illustrated), for example having a generally frustoconical shape, formed so as to fit within the interior of the ends 12a, 32a and 12b and 32b of the arches 10, 30, thereby facilitating rotation of each of the ends thereabout. It comprises an outer rim 54, and two blocks 55 projecting from the body thereof. The outer rim 54 projects radially outwardly from the primary axis X, facilitating retention of the arches 10, 30 by the coupling arrangement when assembled As seem in FIG. 3B, it further comprises a denticulate arresting ring 56 comprising a plurality of teeth 57 protruding inwardly therefrom and defining therebetween a plurality of notches 58.
Reverting to FIG. 3A, the fastener element 53 comprises an attachment portion 60 projecting downwardly therefrom, configured to attach is to the mounting arrangement 70. It further comprises a denticulate arresting ring 56 formed about the primary axis X (not illustrated) and comprising a plurality of teeth 57 protruding inwardly therefrom and defining therebetween a plurality of notches 58. (As the arresting rings 56 of the pivot hubs 51 and fastener elements 53 are similarly constructed and operate similarly, the same reference numerals have been used.)
Each of the arresting rings 56 is disposed such that the teeth 57 thereof is disposed within the seat 56 formed on the interior of one of the ends 12a, 32a and 12b and 32b, as described above, with the end of the respective arresting pin 21 being within one of the notches 58. Thus, each arresting pin 21 and arresting ring 56 together constitute a stop-arrest arrangement, facilitating incremental pivotal displacement of each of the arches 10, 30 about the axis X.
In use, each of the arches 10, 30 may be independently pivoted about the primary axis X. As the arches 10, 30 are thus pivoted, each of the blocks 55 slides within one of the spaces 24, defined between the panels 22, 23 of the ends 12a, 32a and 12b and 32b, as described above. The stoppers 25 define the maximum pivoting range of each of the arches 10, 30, and thus the maximum angle γ (as described below with reference to FIGS. 4A through 4H) which can be formed therebetween, i.e., when each of the arches is pivoted, in opposite directions, as is provided by the stoppers. For example, the stoppers 25 may define a maximum angle γ of at least about 150°. According to some examples, the maximum angle γ is at least about 180°. The stop-arrest arrangement described above facilitates independently arresting each of the arches 10, 30 at one of a plurality of positions (defined by the respective arresting ring 56) within the range defined by the stoppers 25.
As seen in FIGS. 4A through 4H, the independent pivoting of the arches 10, 30 facilitates arranging the activity apparatus 1 is a wide variety of positions (for reference, coupling arrangements 50 is illustrated). For example, the second arch 30 may be maintained in a position (e.g., substantially vertically, as shown), while the first arch 10 is pivoted independently, e.g., as illustrated in the progression from FIG. 4A through 4C, thereby changing an angle γ therebetween. Similarly, the first arch 10 may be maintained in a position, while the second arch 30 is pivoted independently, e.g., as illustrated in the progression from FIG. 4D through 4F, thereby changing the angle γ therebetween. Furthermore, both arches 10, 30 may be moved in different directions independently, e.g., as illustrated in the progression from FIG. 4G to 4H, thereby changing the angle γ therebetween.
As best seen in FIG. 5, the arches 10, 30 may be formed such that one has a length which is less than the other, resulting in, e.g., the first arch 10 having a height H1 which is shorter than a height H2 of the second arch 30. According to this arrangement, the first arch 10 may pass below the second arch 30, for example to lie parallelly thereto, or to facilitate switching the relative positions of the arches 10, 30 without the need to rotate the entire activity apparatus 1.
The activity apparatus 1 may comprise additional arches (e.g., a third arch, a fourth arch, etc., not shown), each designed similarly to the first and second arches 10, 30 as described above, mutatis mutandis. According to this example, the elements of the coupling arrangements 50 are suitably modified to accommodate the extra arches.
As described above, one or both of the arches 10, 30 may be provided with one or more decorative elements 90, which may comprise colors, patterns, textures, etc., for example selected to stimulate an infant. The decorative elements 90 may be configured to dangle, or be articulated directly to the arch body, such as beads attached thereto. Some or all of the decorative elements 90 may be detachably attachable to its respective arch. Some or all of the decorative elements 90 may be integrated with its respective arch.
The activity apparatus 1 may be configured to stimulate activity of an infant and enhance hands and legs motion and coordination. For example, one of the arches 10, 30 may comprises one or more decorative elements 90 designed to stimulate at least one of activity of an infant's hands, sensory faculties (such as sight and/or hearing), etc., with the other of the arches comprising one or more decorative elements designed to stimulate activity of the infant's legs.
As seen in FIG. 6, one or both of the arches 10, 30 may be formed with an integrated decorative element 92, constituting a portion of the arch spanning between its two ends. Furthermore, one or both of the arches 10, 30 may comprise a linear portion 94, i.e., a portion of one or both of the arches may be non-curved. An activity apparatus according to the presently disclosed subject matter may comprise one or both of the features described with respect to FIG. 6 (i.e., the integrated decorative element 92 and the linear portion 94 of the arch), and/or may comprise any one or more of the features described above with respect to FIGS. 1 through 4.
Reverting to FIG. 1, the mounting arrangements 70 facilitate detachably attaching the activity apparatus 1 to an external object, such as a crib, a bed, a bouncer, a safety seat, a cradle, a stroller, etc. Accordingly, it comprises a pair of clamps 75. The distance between the clamps 75 may be adjustable by rotation of a rotating ring 71, thereby facilitating adapting the mounting arrangement 70 to grip external objects of different sizes.
The arches 10 and 30 may be made of a rigid though pliable material, such as for example plastic, providing them with flexibility allowing them to assume different bending states, owing to the distance between the two opposite coupling ends 50 while the activity apparatus 1 is attached to different width of infant equipment thereof.
In addition, due to resiliency of the arches, the activity apparatus 1 may be temporarily and reversibly deformed into a compact position, thereby, e.g., facilitating transporting it.
Each of the arches 10, 30 may be formed with any suitable generally arched shape spanning between its respective ends. For example, one or both of the arches 10, 30 may have a wave shape.
According to a particular configuration, elements of the first arch can interact with elements of the second arch. For example, elements of one arch can have a shape complimentary to the shape of elements of the other arch, whereby when the two arches lie in registration with one another, the shape of two neighboring toys yields a different shape or configuration. Furthermore, there may be an interacting relation between toys and arches by providing proximity-activated elements whereby when such elements near each other an audio signal may be played optionally with lighting of LEDs, etc.
Those skilled in the art to which this invention pertains will readily appreciate that numerous changes, variations and modifications can be made without departing from the scope of the invention mutatis mutandis.
