DETAILED DESCRIPTION
(33) Example embodiments will now be described more fully with reference to the accompanying drawings.
(34) Example embodiments are provided so that this disclosure will be thorough, and will fully convey the scope to those who are skilled in the art. Numerous specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of embodiments of the present disclosure. It will be apparent to those skilled in the art that specific details need not be employed, that example embodiments may be embodied in many different forms and that neither should be construed to limit the scope of the disclosure. In some example embodiments, well-known processes, well-known device structures, and well-known technologies are not described in detail.
(35) The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms a, an, and the may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms comprises, comprising, including, and having, are inclusive and therefore specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. It is also to be understood that additional or alternative steps may be employed.
(36) When an element or layer is referred to as being on, engaged to, connected to, or coupled to another element or layer, it may be directly on, engaged, connected or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being directly on, directly engaged to, directly connected to, or directly coupled to another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., between versus directly between, adjacent versus directly adjacent, etc.). As used herein, the term and/or includes any and all combinations of one or more of the associated listed items.
(37) Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as first, second, and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.
(38) Spatially relative terms, such as inner, outer, beneath, below, lower, above, upper, and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as below or beneath other elements or features would then be oriented above the other elements or features. Thus, the example term below can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
(39) With reference to
(40) The stationary frame assembly 12 may include a pair of armrest frames 16 (
(41) Each of the movable seat assemblies 14 may include a seat bottom assembly 32, a legrest mechanism 34, and one or more backrest support springs 36. As will be described in more detail below, the movable seat assemblies 14 are individually movable relative to the stationary frame assembly 12 among a first position (
(42) Movement of the seat assembly 14 from the first position to the second position may include movement of the legrest mechanism 34 relative to the stationary frame assembly 12 and the seat bottom assembly 32 from the retracted position to the first extended position while the seat bottom assembly 32 remains stationary relative to the stationary frame assembly 12. Movement of the seat assembly 14 from the second position to the third position may include movement of the legrest mechanism 34 relative to the stationary frame assembly 12 from the first position to the second extended position and movement of the seat bottom assembly 32 relative to the stationary frame assembly 12 from the nominal position to the tilt position. In some configurations, the legrest mechanism 34 moves relative to the seat bottom assembly 32 between the first and second extended positions. In other configurations, there is no relative movement between the legrest mechanism 34 and the seat bottom assembly 32 when the legrest mechanism 34 moves between the first and second extended positions.
(43) As shown in
(44) The seat bottom assembly 32 may also include a pair of cams 48 (
(45) As described above, the seat bottom assembly 32 is movable between a nominal position (see
(46) As shown in
(47) As shown in
(48) As shown in
(49) In some configurations, a cable 86 (e.g., a substantially non-stretchable cable) may be attached to both ends of the spring 82 and limits an amount that the spring 82 can be stretched and limits the range of motion of the legrest support members 56 relative to the inserts 76. When the legrest support members 56 are in contact with the flanges 80 of the inserts 76, the cable 86 is in a slack (i.e., not taut) condition (shown in
(50) The ottoman platform 64 may be fixedly mounted to the legrest support members 56 between the first and second ends 66, 72. The ottoman platform 64 may restrict access to inner components of the furniture member 10 and conceal the inner components from a user's view when the legrest mechanism 34 is in the first extended and second extended positions, as shown in
(51) As described above, the cross member 58 is connected to the legrest support members 56 by the inserts 76 and pins 78. As shown in
(52) As shown in
(53) As shown in
(54) As shown in
(55) Once the springs 106 are compressed, continued movement of the slide block 88 toward the second extended position will be transmitted to the seat bottom assembly 32. That is, when the springs 106 are sufficiently compressed, the contact between the bumpers 102 and the cams 48 will cause the seat bottom assembly 32 to move forward with the legrest mechanism 34 as the legrest mechanism 34 continues its movement toward the second extended position (compare
(56) In this manner, movement of the legrest mechanism 34 relative to the stationary frame assembly 12 from the first extended position to the second extended position causes corresponding movement of the seat bottom assembly 32 relative to the stationary frame assembly 12 from the nominal position (
(57) In some configurations, the bumpers 102 are not spring loaded. In such configurations, the bumpers 102 could be rigid members that contact the cams 48 to transmit movement of the legrest mechanism 34 to the seat bottom assembly 32 as the legrest mechanism 34 moves from the first extended position to the second extended position. In such configurations, there might not be any relative movement between the legrest mechanism 34 and the seat bottom assembly 32 as the legrest mechanism 34 moves between the first and second extended positions and the seat bottom assembly 32 moves between the nominal and tilt positions. However, spring-loading the bumpers 102 may reduce or prevent any jarring that an occupant of the furniture member 10 may feel as the bumpers 102 impact the cams 48 to push the seat bottom assembly 32 toward the tilt position.
(58) As shown in
(59) In some configurations, upholstery and padding (not shown) can cover the backrest support springs 36 and the arm rest frames 16. A foldable or stretchable piece of upholstery (not shown) can connect the backrest upholstery with the arm rest upholstery to fill the space between the backrest upholstery and the arm rest upholstery while allowing relative movement between the backrest upholstery and the armrest upholstery.
(60) Operation of the motor 89 to move the slider block 88 rearward will move the legrest mechanism 34 from the second extended position to the first extended position and then to the retracted position. As the legrest mechanism 34 moves from the second extended position toward the first extended position, gravity will cause the seat bottom assembly 32 to move from the tilt position toward the nominal position.
(61)
(62) In the event that an obstruction and/or some outside force restricts movement of the legrest platform 62 and legrest support members 56 from moving toward the retracted position while the slide block 88 of the motor assembly 60 is moving rearward, the inserts 76 can slide partially out of the second ends 72 of the legrest support members 56, as shown in
(63) Referring now to
(64) Like the furniture member 10, the backrest support springs 236 of the furniture member 210 are attached at a first end 225 to a stationary seatback frame 218 and attached at a second end 227 to a rear cross member 241 of the seat bottom assembly 232. A first end 245 of a cable 237 may be attached to a seat bottom support member 238 of the seat bottom assembly 232, and a second end 247 of the cable 237 may be attached to an intermediate portion of the backrest support spring 236 (i.e., a portion between the opposing ends of the backrest support spring 236). The cable 237 may engage one or more pulleys 239 mounted to the stationary frame assembly 212.
(65) When the seat bottom assembly 232 moves from the nominal position (
(66) Furthermore, as described above, because the first end 225 of the backrest support spring 236 is attached to the stationary seatback frame 218 and the second end 227 of the backrest support spring 236 is attached to the seat bottom support member 238, movement of the seat bottom assembly 232 between the nominal and tilt positions also moves the second end 227 of the backrest support spring 236 relative to the first end 225, thereby further contributing to the shape change of the backrest support spring 236.
(67) The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
