Abstract
Description
- The present disclosure relates to juvenile swings, and particularly, to a portable juvenile swing. More particularly, the present disclosure relates to a portable juvenile swing having a foldable frame.
- A conventional juvenile swing apparatus typically has a seat suspended from a floor-supported stand by one or more hanger arms. These conventional juvenile swing assemblies usually comprise some sort of drive mechanism to move the seat and hanger arms back and forth along a swing arc in an oscillatory manner. Some juvenile swings have frames that are collapsible for storage or transport. Other known juvenile swings may be disassembled for storage or transport.
- According to the present disclosure, a swing apparatus comprises a swing and a support stand to which the swing is coupled for swinging movement. The swing comprises a seat and a hanger arm. The support stand comprises a foldable frame having a set of legs that are moveable between an expanded use position and a collapsed storage position.
- In an illustrative embodiment, the support stand comprises first and second housings, four legs, and a linkage assembly that coordinates the folding movement of the four legs between the expanded use position and the collapsed storage position. The housings move toward one another and lower ends of the four legs are drawn towards one another when the frame is moved from the expanded use position to the collapsed storage position. One pair of the four legs serves as a first folding leg assembly having a front leg and a rear leg and the other pair of the four legs serves as a second folding leg assembly having a front leg and rear leg. The illustrative linkage assembly comprises four X-linkage pairs. Each X-linkage pair extends between a respective pair of the four legs. Two of the four X-linkage pairs extend between respective front and rear legs and comprise telescoping links.
- In the illustrative embodiment, the support stand comprises four floor-engaging feet and four sliders. Each of the four floor-engaging feet is coupled to a bottom portion of a respective one of the four legs and each of the four sliders is coupled to a respective one of the four legs for movement therealong. Each of the X-linkage pairs is coupled to a respective pair of the floor-engaging feet and a respective pair of the sliders. The illustrative support stand comprises a stop and a lock coupled to one of the four legs. One of the sliders serves as a control slider that engages the stop when the legs are in the expanded use position. The lock has a locking position in which the control slider is unable to move away from the stop, thereby locking the legs in the expanded use position. The lock has a releasing position in which the control slider is able to move away from the stop to permit the legs to move from the expanded use position to the collapsed storage position.
- Also in the illustrative embodiment, the swing apparatus has a pair of hanger arms and the seat is detachable from the pair hanger arms. The seat is at least partially collapsible when detached from the pair of hanger arms. The seat has a foldable seat frame and a set of panels coupled to the foldable seat frame. Each hanger arm includes a member and a coupling body coupled to the member. The seat has a pair of joints that couple portions of the foldable seat frame together for pivoting movement. The joints are attachable to the coupling bodies of the hanger arms, and when attached, the coupling bodies prevent the joints from pivoting, thereby preventing the seat frame from folding.

A fastener (not shown), such as a bolt or rivet, couples strut 76 tosocket 168.Boss 162 ofbody 114 has abore 170 that is sized to receiveboss 138 ofbody 116 therein for rotation aboutaxis 74. Abolt 172 threads intoboss 138 and the head ofbolt 172 engages ashoulder 174 ofboss 162 to prevent separation ofbodies - When
seat 42 is attached tohanger arms 40,first axis 82 of joint 80 is parallel with and spaced by a large distance fromsecond axis 90 of joint 88 as shown inFIGS. 1 and 2 . Afterseat 42 is detached fromhanger arms 40,frame member 68 ofseat frame 50 andpivot bodies 114 are pivotable aboutaxis 74 between a first position in which axes 82, 90 are spaced by the large distance, shown inFIG. 6 , and a second position in whichaxis 92 is very close to or even coaxial withaxis 90 as shown inFIGS. 6 and 7 (in phantom inFIG. 6 ). In the illustrative embodiment,frame member 68 andbodies 114 pivot aboutaxis 74 through about one hundred eighty degrees when moving between the first and second positions. - Due to the large spacing between
axes joints 72,portions frame member 68 are unable to fold aboutaxis 80 andportions frame member 70 are unable to fold aboutaxis 90 whenframe member 68 andpivot bodies 114 are in the first position. However, afterframe member 68 andbodies 114 are pivoted to the secondposition having axis 82 very close to, or coaxial with,axis 90,portions frame member 68 andportions frame member 70 are able to fold aboutaxes seat frame 50 as shown inFIG. 8 . Asseat frame 50 collapses, joints 72 move toward each other indirections 91, shown inFIG. 7 , andseat sling 52 bunches or folds in a somewhat random manner. In addition,rods 66 ofcanopy 62 are further flexed whenseat frame 50 collapses. It should be understood that, due to clearances in various components ofseat frame 50 and due to a slight amount of flexibility in various components ofseat frame 50,axis 82 need not be coaxial withaxis 90 in order forportions frame member 68 andportions frame member 70 to fold aboutaxes frame member 68 andbodies 114 are in the second position. - After
seat 42 is detached fromhanger arms 40, support stand 22 may be moved from the expanded use position to the collapsed storage position as mentioned above. Upper end portions offront legs 26 and upper end portions ofrear legs 28 are coupled torespective housings housings rear legs 28 and eachfront leg 26 is pivotable relative to therespective housings leg pivot axis 176. Thus, a firstfolding leg assembly 36 is provided on a right side ofswing apparatus 20 byhousing 32 and the associatedlegs folding leg assembly 38 is provided on the left side ofswing apparatus 20 byhousing 34 and the associatedlegs -

Two offeet 180 are pivotably coupled to the lower end portions ofrespective legs 26 and two offeet 180 are pivotably coupled to the lower end portions of respectiverear legs 28.Stand 22 further comprises foursliders 182 that are coupled tolegs legs legs legs respective axes 194 by respective pivot pins orbolts 184. Ahub 186 is provided at the pivotable connection between leg supports 30 of each X-linkage pair. Eachhub 186 comprises twohub halves 188 which are coupled to leg supports 30 byrespective pins 184. Eachhub half 188 pivots with an associated one of leg supports 30. - As
stand 22 moves from the expanded use position to the collapsed storage position,sliders 182 move alongrespective legs foot 180 and toward the associatedhousings sliders 182 move alonglegs housing respective axes 194 to draw the fourfeet 180 toward one another and to drawhousings stand 22 are telescoping leg supports 30 and comprise afirst portion 196 which is pivotably coupled to arespective slider 182 and asecond portion 198 which is pivotably coupled to arespective foot 180. - When stand 22 is in the expanded use position,
portion 198 is in an extended position relative toportion 196 and when stand 22 is in the collapsed storage position,portion 196 is in a retracted position relative toportion 196. The leg supports 30 of the X-linkage assemblies at the front and rear ofstand 22 are non-telescoping leg supports 30. Thus, the leg supports 30 at the sides ofstand 22 coordinate the folding movement oflegs housings stand 22 control the lateral distance between thehousing legs housings stand 22,hanger arms 40 move toward one another.Joints 95 ofhanger arms 40permit members hanger arms 42 nest compactly within spaces betweenlegs FIG. 10 . - The following description of one of
