Description
- The present invention is a soothing device for infants, and more particularly a rocking-type infant soothing device.
- In the past there have been many different types of infant soothing devices. Of particular popularity have been standard infant swings having an “A” frame configuration. In a typical swing configuration of this type, the swing structure generally consisted of two A-shaped legs that were attached by a lateral crossbar or axle at the top vertices of the A's. Typically, the swing itself was hung from the crossbar and a motor, usually either spring or electric, provided the motive force for moving the swing. In these prior configurations, the motor was usually located somewhere on one of the two leg structures, fairly close to the rotational axis of the axle and was directly connected to the swing seat. Examples of these types of prior art swings are shown in U.S. Pat. Nos. 4,452,446 and 5,378,196.
- Recently, improved “open top” versions of these basic “A” frame type infant swings have gained popularity because there is no crossbar or axle which runs directly across the top of the support structure over the top of the seat. These newer style “open top” swings allow much easier access to the child occupant than the prior art swings discussed above. Examples of typical “open top” swings include U.S. Pat. No. 5,525,113 owned by Graco Children's Products, Inc., U.S. Pat. No. 5,769,727 owned by Evenflo Company Inc. and U.S. Pat. No. 5,791,999 owned by Kolcraft Enterprises, Inc. As can be seen in all of these patents, there is no axle or crossbar that extends directly over the top of the swing and stability is provided by attaching the bases of the A-shaped legs, rather than the vertices of the A's as in prior art swings.
- Other types of infant soothing devices, including rockers, rocking cribs, etc. have also been disclosed in the prior art. Representative examples of these types of infant soothing devices are disclosed in U.S. Pat. No. 5,711,045 assigned to Andrew Caster, U.S. Pat. No. 5,464,381 to Christi L. Wilson, U.S. Pat. No. 4,752,980 assigned to D&M Rocker, and U.S. Pat. No. 4,620,334 to Alec Robinson, among many others.
- The present invention provides an improved infant soothing device. More specifically, the present invention provides a rocking-type infant soothing device having a drive mechanism wherein there is no direct linkage between the infant retention structure and the motive force for moving and/or rocking the infant retention structure. In one embodiment, the invention comprises an infant retention structure that is coupled to a carriage wherein the carriage moves in a reciprocating motion in response to the up and down movement of a platform that is pivotally supported by a base. In other embodiments, the infant retention structure may be a seat mounted so that may be reclined without significantly changing the center of gravity of the seat with respect to the carriage; the carriage may ride on wheels within a track in the platform; a damper device, such as a piston, may be provided to facilitate the delivery of a smooth rocking motion to the rocking platform and thus the infant retention structure; legs may be provided in the base of the infant soothing device and the legs may be movable between retracted and extended positions; the infant soothing device may be driven by an electric motor; and the electric motor may be battery operated. Upon review of the disclosure presented herein, one of ordinary skill in the art will realize that many of the embodiments disclosed may be combined and varied without departing from the scope of the invention.

- As best shown in FIGS. 1, 2 and3, one embodiment of the present invention is an infant
soothing device 20 including abase 22, arocking platform 24 and an infant retention structure such as a carriage/seat combination 26. Thebase 22 may optionally includelegs 28 that may be extendable and retractable with respect to thebase 22. Thelegs 28 may be attached to thebase 22 as is generally known in the art to raise and lower thebase 22 thereby adjusting the height of thebase 22 as may be desired. Thelegs 28 may be of a generally tubular construction and may include L-shaped feet 30 includingbumpers 32 positioned on the vertices of thefeet 30 to provide desired stability. Therocking platform 24 may be pivotally mounted with respect to thebase 22 at acentral pivot point 34. Therocking platform 24 may include atrack 40 that may be upwardly curved in shape. Thetrack 40 may be made of any suitable construction and may be comprised of separate pieces includingrail wells 42 that receive and support thewheels 36 of thecarriage 38 andcover pieces 44 that are positioned over therail wells 42 to capture thewheels 36 of thecarriage 38 and prevent the carriage from becoming disengaged from thetrack 40. Therail wells 42 may include a rail (not shown) upon which thewheels 36 of thecarriage 36 are supported and may glide upon. Of course it is to be understood that other types of configurations for movement of the carriage/seat combination on the rocking platform are possible and would be within the scope of the invention. For example, the carriage could roll on the surface of the rocking platform itself, rather than in a track on the platform, or the movement of the carriage could be restricted by a slider/rail combination. Additionally, the wheels of the carriage could be replaced with bearings or sliding mechanisms as is known in the art. - Base
- As best shown in FIG. 4, and as described generally above, an embodiment of the infant soothing device of the present invention may include a
base 22 optionally includinglegs 28 that may be extendable and retractable with respect to thebase 22. Thebase 22 may be shaped so that thebase 22 can sit securely on a flat surface whether or not thelegs 28 are extended or retracted. Thelegs 22 may be made of any suitable construction and any suitable material. For example, thelegs 28 may be tubular steel and may be pivotally attached to thebase 22 in any traditional manner known in the art so that they may be extended and retracted as desired. In one embodiment of the invention thelegs 28 may be included in aleg assembly 46 includingleg brackets 48, overbuttons 50, resilientlybiased stop buttons 52, and pivot axles (not shown). Thelegs 28,leg brackets 48 and overbuttons 50 may includepivot holes 54 formed therethrough to receive the pivot axles for relative pivotal movement. Thelegs 28 andleg brackets 48 may also includedetent holes 56 for receivingnubs 58 on the resiliently-biased stop buttons 52 to prevent undesired retraction of thelegs 28 when thelegs 28 are in the extended position. Accordingly, when thelegs 28 are in the extended position, thenubs 58 on the resiliently-biased stop buttons 52 engage thedetent holes 56 in thelegs 28 andleg brackets 48, thereby preventing retraction of thelegs 28. When retraction of thelegs 28 is desired, the overbuttons 50 may be pressed inwardly, thereby disengaging thenubs 58 from thedetent holes 56 and allowing retraction of thelegs 28. As best shown in FIG. 3,recesses 60 may be provided on the underside of thebase 22 to receive thelegs 28 when the legs are in a retracted position. - The
base 22 may include a motor assembly/drive mechanism, generally designated 62, as will be discussed in detail below. Thebase 22 may include amotor control unit 64, including apower switch 66 and aspeed control 68. Themotor control unit 64 may be electrically connected tobatteries 70 to control the current from thebatteries 70 to the motor assembly/drive mechanism 62 as is known in the art. Thebatteries 70 may be held into thebase 22 by aremovable battery cover 72 as is known in the art. Thepower switch 66 may be any suitable switch, such as a standard single-pole, double-throw switch and the speed control can be any suitable control circuit capable of varying the current to the motor assembly/drive mechanism 62, such as a pulse width modulation control or a rheostatic control, among others. - The
base 22 may include a pivot mechanism for supporting the rockingplatform 24. The pivot mechanism may be any suitable mechanism for attaching the rockingplatform 24 to the base 22 in a pivotable fashion. The pivot mechanism may include pivot supports 74 for supporting a pivot axle (not shown) that extends along line A-A (see FIG. 5). The pivot supports 74 may be integrally formed in the base 22 or may be held in place by screws, rivots, etc. The rockingplatform 24 may have pivot holes or slots (not shown) formed therein for receiving the pivot axle (not shown) so that the rockingplatform 24 may pivot about the pivot axle. - As best seen in FIG. 7, the
base 22 may include protrudingfms 76 for receiving one end of table springs 78. As best seen in FIG. 8, the underside of the rockingplatform 24 may include a well 79 for receiving the other end of table springs 78. The table springs 78,base 22, rockingplatform 24, andcarriage 38 all may cooperate to form a mechanism having rocking and rolling motion. The rocking and rolling motion of the mechanism generally operates at a natural periodic frequency that is determined by the selection and construction of those components. It is to be understood that the selection and construction of those components may be manipulated by one of ordinary skill in the art to achieve a natural periodic frequency as may be desired to attain the desired rocking motion. In this regard, one of ordinary skill in the art will understand that the selection and positioning of the table springs 78 may be varied greatly from the embodiment disclosed herein and the invention is not intended to be limited to that embodiment. For example, any number of table springs, including as few as one or as many as desired, may be utilized and operably connected between the rocking platform and the base to achieve the desired motion. Furthermore, the table springs may be the compression springs shown herein, or may be chosen from other springs including leaf springs, torsion springs, extension springs, elastomeric springs, etc. as is known in the art. - In an embodiment of the invention the base22 (in combination with the rocking platform 24) may include a damper mechanism. The damper mechanism may be used to prevent undesired rocking and vibration in the rocking
platform 24. The damper mechanism may be any damper mechanism as is known in the art and may be anair piston 80. As best shown in FIG. 4, theair piston 80 may include adamper cup 82 positioned in thebase 22 and apiston 84 attached to the underside of the rockingplatform 24 as best seen in FIGS. 7 and 8. Thepiston 84 may be attached to the rockingplatform 24 in any suitable manner and may be hung from the bottom of the rockingplatform 24 using ahanger 86/axle 88 combination. As shown best in FIG. 7, thehanger 86 may be offset from the center of thepiston 84 to prevent undesired rattling noises. Thehanger 86 may have aslot 90 therein to receive theaxle 88 to allow thepiston 84 to move somewhat with respect to the rockingplatform 24 as the rockingplatform 24 pivots up and down on thebase 22. Theaxle 88 may be anchored in the underside of the rockingplatform 24 as desired. - The
piston 84 may be sized to fit suitably within thedamper cup 82 whereby the air displaced by thepiston 84 as the rockingplatform 24 moves up and down with respect to the base 22 escapes out of thedamper cup 82 along the sides of thepiston 84. Of course an air valve could also be used to control the flow of air in and out of thedamper cup 82 as is known in the art to provide the desired dampening effect. Thedamper cup 82 may include an attachedflange 92 to allow thedamper cup 82 to be fastened into acollar 94 included in the base 22 or may be molded directly into thebase 22. Of course, it is to be understood that the attachment of thedamper cup 82 andpiston 84 with respect to thebase 22 and rockingplatform 24, respectively, could be reversed without departing from the scope of an embodiment of the invention. - Rocking Platform
- As best shown in FIG. 5, an upper portion, or topside, of a rocking
platform 24 in accordance with an embodiment of the invention may include acentral pivot point 34 and atray 96 including atrack 40. As discussed previously, thetrack 40 may includerail wells 42 for providing a clearance area forwheels 36 attached to acarriage 38 and coverpieces 44 for retaining thewheels 36 in therail wells 42. Therail wells 42 may additionally include rails (not shown) to provide a riding surface for thewheels 36. Thetrack 40 may be curved to provide a smooth ride for thecarriage 36 and thus provide a soothing motion to the infant utilizing thesoothing device 20. The curvature of thetrack 40 may be generally curved, arcuate, parabolic or compound. The rockingplatform 24 may include acentral pivot point 34 that is adapted to receive a pivot axle (not shown) along axis A-A such that the rockingplatform 24 is pivotally mounted with respect to thebase 22. As best shown in FIG. 8, and as will be discussed in detail below, in accordance with an embodiment of the present invention, the underside of the rockingplatform 24 may be adapted to pivotally mount the rockingplatform 24 with respect to the base 22 in an operative connection with a motor assembly/drive mechanism 62. For this purpose, a mountingblock 96 and a mountingpost 98 may be attached to the underside of the rockingplatform 24. - Motor Assembly/Drive Mechanism
- As best shown in FIGS. 7 and 8, a motor assembly/
drive mechanism 62 may be provided in accordance with an embodiment of the invention. In an embodiment of the invention, the motor assembly/drive mechanism 62 may include amotor reduction assembly 100 as is known in the art, an eccentric crank 102, a slidingcouple 104, a mountingbracket 106, and atorsion drive spring 108. Themotor reduction assembly 100 may be electrically connected to themotor control unit 64, and more specifically, thespeed control 68. Themotor reduction assembly 100 may be secured to thebase 22. Theeccentric crank 102 may rotate about axis B-B of themotor reduction assembly 100. The slidingcouple 104 includes adrive bore 110 that is parallel to the eccentric crank 102 and shaped to rotatably receive theeccentric crank 102. The slidingcouple 104 also includes atransverse bore 112 that is shaped to slidably receive a drive end 114 of thetorsion drive spring 108. The mountingbracket 106 is fixedly attached to the mountingblock 96 and includes abore 116 therein to rotatably receive amiddle section 118 of thetorsion drive spring 108. The mountingpost 98 includes abore 120 shaped to receive a screw (not shown) to fixedly attach atorsion end 122 of thetorsion drive spring 108 to the underside of the rockingplatform 24. - Accordingly, when current is supplied to the
motor reduction assembly 100 from thebatteries 70 thereby causing the eccentric crank 102 to turn, the up and down movement of thecrank 102 is translated through the slidingcouple 104 to thetorsion drive spring 108. Thetorsion end 122 of thetorsion drive spring 108 is then driven up and down with respect to thebase 22, while the slidingcouple 104 slides back and forth on the drive end 114 of thetorsion drive spring 108, thereby providing a smooth rocking motion to the rockingplatform 24 attached thereto. Theair piston 80 help to dampen and smooth the up and down movement of the rockingplatform 24 as well. - While the motor assembly/drive mechanism described herein is considered to be operable in connection with the present invention, it is to be understood that there are many motor assembly/drive mechanisms that would be operable in connection with the infant soothing device of the present invention, all of which would be considered within the scope of the present invention. In particular, one of ordinary skill in the art would understand that many motor assemblies/drive mechanisms known in the prior art having rotating or reciprocating outputs could be operatively coupled between the base and rocking platform of the present invention using a compliant linkage to induce the desired rocking motion to the rocking platform. With respect to compliant linkages, several embodiments are known in the art which would be operable and are considered within the scope of the present invention including leaf springs, extension springs, spirally wound torsion springs, etc. As such, the motor assembly/
drive mechanism 62 andtorsion spring 108 specifically described herein are simply one operative embodiment for use in connection with the present invention. - Carriage/Seat Combination
- As best shown in FIG. 6, an embodiment of the invention may include a carriage/
seat combination 26 wherein an infant using the infantsoothing device 20 of the present invention is held in aseat 124 that is attached to thecarriage 38. It is to be understood that other infant retention structures not specifically described herein, including harness devices, pivoting reclinable seats, and/or platforms would be operable in embodiments of the invention and are considered within the scope of the invention. - The carriage/
seat combination 26 may include aseat 124, aseat platform 126, acarriage 38, andwheels 36. Theseat platform 126 may be integral with theseat 124 or theseat 124 may be removable from theseat platform 126. If theseat 124 is removable from theseat platform 126, the seat back 128 may include retention blocks 130 thereon shaped to be received in aslot 132 in theseat platform 126. The mounting blocks 130 may include resiliently biasedfingers 134 formed therein includingnubs 135 thereon shaped to be received byretention holes 136 in theseat platform 126slot 132. Accordingly, if it is desired to remove theseat 124 from theseat platform 126, thenubs 135 on the resiliently biasedfingers 134 may be pushed inwardly, disengaging thenubs 135 from the retention holes 136 thereby allowing theseat 124 to be disengaged from theseat platform 126. Additional mechanisms may be used to additionally secure theseat 124 to theseat platform 126 including having aslide 138 mounted on the seat back 128 to engage acorresponding fin 140 mounted on theseat platform 126. Additionally,notches 142 on theseat platform 126 may be shaped to engage protrusions 144 (best seen in FIG. 5) on thebase 146 of theseat 124 further securing theseat 124 to theseat platform 126. - The
seat platform 126, andseat 124 attached thereto, may be fixedly attached with respect to thecarriage 38, or may be movable in any desired manner including pivotally or slidably. If theseat platform 126 is slidably attached to thecarriage 38, thecarriage 38 may include acurved track 148 formed inupper part 150 thereof to slidably receive lower 152 and upper 154 sliding blocks positioned on theseat platform 126. Thetrack 148 may be formed with a curvature such that the sliding of theseat platform 126, and thus the seat 124 (and any infant seated in the seat), does not appreciably change the center of gravity of the infant with respect to thecarriage 38. In this manner, the movement of the carriage/seat combination 26 in thetrack 40 is not appreciably changed by the movement of theseat platform 126 within thecarriage 38. - In one embodiment of the invention, the
seat platform 126 may be made essentially infinitely adjustable with respect to thecarriage 38 by positioning a gear tooth track on the bottom of theseat platform 126 and including a resiliently biased detent mechanism to engage the track as is known in the art. Alternately, thebottom 156 of theseat platform 126 may include a detent block 158 positioned thereon that is shaped to interfere with aprotrusion 160 positioned on an engagement portion 162 of a resiliently biased pivot release button 164. The pivot release button 164 may be pivotally journaled into thecarriage 38 by apivot nub 166 and may include a spring 168 positioned under theoperation surface 170 of the pivot release button 164. Accordingly, when theoperation surface 170 is depressed, theprotrusion 160 may be moved out of interference with the detent block 158 and theseat platform 126 may be slid between a rearward, upright position and a forward, reclined position. Then, when theoperation surface 170 is released, the detent block 158 may be resiliently biased into interference with theprotrusion 160 by the spring 168. Thus, given the positioning of the lower 152 and upper 154 sliding blocks in thetrack 148, forward and rearward movement of theseat platform 126 with respect to thecarriage 38 is prevented. - The
carriage 38 may be constructed to move smoothly back and forth in the rockingplatform 24. In order to facilitate the smooth movement of thecarriage 38, thecarriage 38 may includewheels 36 positioned thereon as is known in the art. While thewheels 36 may be of any conventional construction, thewheels 36 may be independently rotatable and mounted onaxles 172 that are mounted in alower portion 174 of thecarriage 38. Thewheels 36 may be provided withbearings 176 to reduce the friction between theaxles 172 and thewheels 36.
