Description

FIELD

The present disclosure relates to motion furniture, and more particularly, to a reclining chaise mechanism.

BACKGROUND

This section provides background information related to the present disclosure and is not necessarily prior art.

In furniture (e.g., chaise lounges, chairs, sofas, loveseats, etc.), functionality is often a tradeoff with aesthetic design. That is, the aesthetic design options of many conventional furniture members often limit motion functionality that can be incorporated into the furniture member. Additionally, furniture members that do offer motion functionality often utilize a complex reclining mechanism with different components for mechanical and powered options. The present disclosure provides furniture members that incorporate aesthetics and functionality that are not found in conventional furniture members.

DETAILED DESCRIPTION

Example embodiments will now be described more fully with reference to the accompanying drawings.

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.

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.

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.

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.

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.

With reference to FIGS. 1-2, a furniture member 50 is provided that may include a seat bottom frame 52, a seatback frame 54, an armrest frame 56, and a reclining mechanism 58. The furniture member 50 has a first furniture end 60 and a second furniture end 62. The furniture member 50 may be a chaise.

Each of the first and second side panels 64, 66 may be orthogonally connected to the front panel 68 at opposite ends of the front panel 68. The cross member 70 extends laterally and may be fixedly attached to the first and second side panels 64, 66 at opposite ends. The springs 72 may be disposed longitudinally and fixedly attached to the front panel 68 and the cross member 70.

The seatback frame 54 may be coupled to the seat bottom frame 52 by a pair of linkages 74 that allow the seatback frame 54 to move relative to the seat bottom frame 52 between the upright position (FIG. 1) and the fully reclined position (FIG. 2). The seatback frame 54 may include a first seatback panel 76, a second seatback panel 78, a top seatback panel 80, and a seatback support panel 82. The first and second seatback panels 76, 78 extend longitudinally. The top seatback panel 80 and the seatback support panel 82 extends laterally. The top seatback panel 80 may be fixedly attached to the first seatback panel 76 and the second seatback panel 78 at opposite ends. The seatback support panel 82 may be fixedly attached to the first seatback panel 76 and the second seatback panel 78 at opposite ends.

The armrest frame 56 may be fixedly attached to the first or second side panel 64, 66. A right armrest (not shown) is defined when the armrest frame is attached to the first side panel 64. As shown in FIGS. 1 and 2, a left armrest 84 is defined when the armrest frame 56 is attached to the second side panel 66.

While not shown in the figures, the seat bottom frame 52, seatback frame 54, and armrest frame 56 may support cushions and may be covered with upholstery. In some configurations, support springs may be attached to the seatback frame 54 and the support springs may support cushions.

With reference to FIGS. 3 to 18, the reclining mechanism 58 may include a front support member 86, a rear support member 88, the pair of linkages 74, a release mechanism 90, a cable 92, and a gas spring 94.

As shown in FIGS. 3 to 5, the front support member 86 includes a first end 96 and a second end 98. A first bracket 100 may be disposed at the first end 96. A second bracket 102 may be disposed at the second end 98. The first and second brackets 100, 102 may fixedly attach the front support member 86 to the seat bottom frame 52. The front support member 86 may include a first clevis 104 positioned between the first and second ends 96, 98. In the configuration shown in the figures, the first clevis 104 is positioned approximately equidistantly between the first and second ends 96, 98. The first clevis 104 may extend from the front support member 86 toward the second furniture end 62.

The rear support member 88 includes a first end 106 and a second end 108. The rear support member 88 may be generally U-shaped. For example, the rear support member 88 may have a first bend 110 near the first end 106 and a second bend 112 near the second end 108. The rear support member 88 may include a front wall 113, a rear wall 115 (FIG. 5), an inner wall 117, and an outer wall 119 that cooperate to form a tube-like configuration. An intermediate portion 111 of the rear support member 88 may extend between the first and second bends 110, 112. The first and second bends 110, 112 may have an angle 114 of approximately 90 degrees to form the U-shape of the rear support member 88. The first and second ends 106, 108 of the rear support member 88 may be attached to respective linkages 74. The rear support member 88 may include a second clevis 116 disposed between the first and second bends 110, 112. In the configuration shown in the figures, the second clevis 116 may be positioned approximately equidistantly between the first and second bends 110, 112. The second clevis 116 may extend from the rear support member 88 toward the first furniture end 60 and may be aligned with the first clevis 104.

As shown in FIGS. 4 and 5, each of the first and second clevises 104, 116 may include a back wall 118 and pair of protruding walls 120. The back wall 118 of the first clevis 104 may be attached to the front support member 86 and the back wall 118 of the second clevis 116 may be attached to the rear support member 88. The pair of protruding walls 120 may extend from the back wall 118 at opposite ends of the back wall 118. A clevis pin 124 (or fastener) may extend through each protruding wall 120. The clevis pins 124 may couple the first and second clevises 104, 116 with the gas spring 94.

Movement of the seatback frame 54 between the upright position and the fully reclined position causes corresponding and simultaneous movement of the rear support member 88 relative to the seat bottom frame 52 and the seatback frame 54. More specifically, the rear support member 88 may move with the pair of linkages 74 between a first position (FIG. 4) and a second position (FIG. 5). The rear support member 88 is in the first position when the seatback frame 54 is in the upright position. The rear support member 88 is in the second position when the seatback frame 54 is in the fully reclined position. In the first position, the rear support member 88 is angled generally toward the second furniture end 62. In the second position, the rear support member 88 is angled generally toward the first furniture end 60. Thus, in the second position, the intermediate portion 111 of the rear support member 88 is horizontally forward relative to the first position (i.e., the intermediate portion 111 is closer to the first furniture end 60 in the second position than in the first position).

The pair of linkages 74 may be attached to the seat bottom frame 52, seatback frame 54, and rear support member 88. The pair of linkages 74 allow the seatback frame 54 to move relative to the seat bottom frame 52 between the upright position (FIGS. 1 and 4) and the fully reclined position (FIGS. 2 and 5). The pair of linkages 74 allow the rear support member 88 to move between the first position (FIG. 4) and the second position (FIG. 5). One of the linkages 74 may be coupled to the second side panel 66, second seatback panel 78, and the first end 106 of the rear support member 88. The other linkage may be coupled to the first side panel 64, the first seatback panel 76, and the second end 108 of the rear support member 88.

Referring now to FIGS. 6 and 7, each of the linkages 74 may include a first link 126, a second link 128, and a third link 130. The first link 126 includes a first link end 132 and a second link end 134. The first link end 132 may be fixedly attached to the seatback frame 54. The second link end 134 may be rotatably coupled to the seat bottom frame 52 (e.g., via a support block 136 and bracket 137). The second link 128 includes between a first link end 138 and a second link end 140. The first link end 138 may be rotatably coupled to the first link 126. The second link end 140 may be rotatably coupled to the third link 130. The third link 130 includes a first link end 142 and a second link end 144. The first link end 142 may be rotatably coupled to the seat bottom frame 52 (e.g., via the support block 136 and bracket 139). The second link end 144 may be fixedly attached to the rear wall 115 of the rear support member 88. That is, the first end 106 of the rear support member 88 may be fixedly attached to the second link end 144 of the third link 130 of one of the linkages 74, and the second end 108 of the rear support member 88 may be fixedly attached to the second link end 144 of the third link 130 of the other one of the linkages 74.

During movement of the seatback frame 54 between the upright position (FIG. 6) and the fully reclined position (FIG. 7), the first link 126, the second link 128 and the third link 130 simultaneously move. For example, a force applied to the seatback frame 54 may drive the first link 126 to pivot at the second link end 134 and simultaneously move the second link 128 and third link 130, thereby moving the rear support member 88 between the first and second positions.

FIG. 8 depicts another example of a third link 141 that can be incorporated into the furniture member 50 instead of the third link 130. The third link 141 includes a first link end 143 and a second link end 145. The first link end 143 may be rotatably coupled to the seat bottom frame 52 (e.g., via the support block 136 and bracket 139). The second link end 145 is fixedly attached to the rear support member 88. More specifically, the second link end 145 is fixedly attached to the outer wall 119 of the rear support member 88. That is, the first end 106 of the rear support member 88 may be fixedly attached to the second link end 145 of the third link 141 of one of the linkages 74, and the second end 108 of the rear support member 88 may be fixedly attached to the second link end 145 of the third link 131 of the other one of the linkages 74.

The first cable collar 206 may be received within the first cable aperture 178 of the base bracket 148.

The release lever 146 is movable between a non-actuated position (FIG. 9) and an actuated position (FIG. 10). The user may apply a force F1 to the release lever 146 at the graspable portion 154. When the force F1 is applied, the release lever 146 rotates (relative to the base bracket 148) about the first connector 194 which simultaneously moves the link 150 vertically upward relative to the base bracket 148. As the link 150 moves vertically upward, the oblong opening 184 of the link 150 moves along the third connector 198 to slide the second opening end 188 of the oblong opening 184 toward the third connector 198. The movement of the link 150 upward applies a pulling force on the cable 92 (i.e., the first cable head 204 is moved vertically upward). The user may release the release lever 146 (i.e., stop applying force F1) to allow the spring 152 to urge the release lever 146 back to the non-actuated position and thereby release the cable 92.

The release mechanism 90 can have a variety of different configurations that allow the user to move the release mechanism 90 between an actuated position and a non-actuated position, resulting in the pull and release of the cable 92. For example, the release mechanism 90 may lock into the actuated position and user may apply a force at the graspable portion 154 of the release lever 146 to move the release mechanism 90 from the actuated position to the non-actuated position.

FIGS. 11-13 depict another example of a release mechanism 212 that can be incorporated into the furniture member 50 instead of the release mechanism 90. As shown in FIG. 11, the release mechanism 212 may be mounted to the armrest frame 56 or to the seat bottom frame 52, for example. The release mechanism 212 may include a housing or base bracket 214 and a release lever 216. The housing 214 includes a pivot 218 and an opening 220. The release lever 216 is rotatably coupled to the housing 214 at the pivot 218. The release lever 216 extends through the opening 220 of the housing 214. The control end 200 of the cable 92 is attached to the release lever 216 such that movement of the release lever 216 causes corresponding movement of the cable 92.

An end 222 of the release lever 216 may include a lip or flange 224. In some configurations, the end 222 of the release lever 216 can include a ring, knob, and/or any other feature that allows the user to easily grip and pull on the release lever 216. The user may rotate the release lever 216 upward and outward from the housing 214 by applying a force F2 to the lip 224 with one or more of the user's fingers, for example. When the user applies the force F2, the release lever 216 rotates at the pivot 218 from a non-actuated position (FIG. 12) to an actuated position (FIG. 13). When the user releases the lip 224, a spring may urge the release lever 216 back toward the non-actuated position.

Although the examples shown in FIGS. 9-13 include a handle-type and a pull-type release lever, another suitable type of release lever may be attached to the cable 92 and may move between an actuated position and a non-actuated position.

With reference to FIGS. 14-18, the gas spring 94 moves between an extended position (FIGS. 14-16) and retracted position (FIGS. 17 and 18) with the movement of the seatback frame 54 between the upright and fully reclined positions. When the seatback frame 54 is in the upright position, the gas spring 94 is in the extended position. When the seatback frame 54 is in the fully reclined position, the gas spring 94 is in the retracted position.

The gas spring 94 may include a rod 226, a tube or cylinder 228, a first clevis connection 230, and a second clevis connection 232. The rod 226 includes a first rod end 234 and a second rod end 236 (FIGS. 16 and 18). The tube 228 includes a first tube end 238 and a second tube end 240. The tube 228 includes an opening or aperture 242 that may include an open end at the first tube end 238 and a closed end 246 (FIGS. 16 and 18) disposed between the first and second tube ends 238, 240.

The rod 226 may be received in the aperture 242 of the tube 228. The first rod end 234 is positioned outside of the tube 228 and the second rod end 236 is positioned within the aperture 242. The rod 226 may be movable relative to the aperture 242 in a telescoping (or reciprocating) manner.

The first clevis connection 230 is disposed at the first rod end 234. The first clevis connection 230 may be fixedly attached to or integrally formed with the rod 226. The first clevis connection 230 rotatably engages the clevis pin 124 of the first clevis 104 of the front support member 86. The second clevis connection 232 is disposed at the second tube end 240. The second clevis connection 232 may be fixedly attached to or integrally formed with the tube 228. The second clevis connection 232 rotatably engages the clevis pin 124 of the second clevis 116 of the rear support member 88.

The first clevis connection 230 may include a main body 247 and a release arm 248 that is rotatably coupled to the main body 247. The main body 247 is fixed to or integrally formed with the rod 226 and includes an aperture 250. The release arm 248 extends at least partially through the aperture 250 and is rotatable therein relative to the main body 247. The gas spring end 202 of the cable 92 may be attached to the release arm 248.

The release arm 248 rotates within the aperture 250 relative to the main body 247 between an actuated position (FIG. 14) and a non-actuated position (FIGS. 15-18). The position of the release arm 248 corresponds to the position of the release mechanism 90. More specifically, when the release mechanism 90 is in the non-actuated position, the release arm 248 is in the non-actuated position, and when the release mechanism 90 is in the actuated position, the release arm 248 is in the actuated position. When the release mechanism 90 is actuated by the user, the cable 92 pulls the release arm 248 from the non-actuated position (FIG. 15-18) toward actuated position (FIG. 14).

Movement of the release arm 248 from the non-actuated position to the actuated position unlocks the rod 226 to slide within the aperture 242 of the tube 228 in a telescoping manner. As shown in FIGS. 16, the rod 226 may move away from the closed end 246 of the aperture 242 to place the gas spring 94 in the extended position. As shown in FIGS. 18, the rod 226 may slide towards the closed end 246 to place the gas spring 94 in the retracted position. Movement of the rod 226 toward the closed end 246 may build up gas pressure in the aperture 242. The built-up gas pressure in the aperture 242 can be used to move the rear support member 88 from the second position (corresponding to the fully reclined position of the seatback frame 54) toward the first position (corresponding to the upright position of the seatback frame 54). In this manner, the gas spring 94 biases the seatback frame 54 toward the upright position when the release mechanism 90 is in the actuated position. When the release mechanism 90 is in the non-actuated position, the gas spring 94 restricts or prevents movement of the seatback frame 54 between the upright and fully reclined positions.

In some configurations, the furniture member 50 may include an auto-return feature for moving the seatback frame 54 from the fully reclined position or one of the intermediate positions to the upright position. When the furniture member 50 is in the fully recline position or one of the intermediate positions, an occupant of the furniture member 50 may apply a force against the seatback frame 54 while the occupant rests against the seatback frame 54.

In one example of the auto-return feature, the furniture member 50 may be able to sense when the occupant of the furniture member 50 lifts from the seatback frame 54 (e.g., when the occupant no longer applies the force against the seatback frame 54) and automatically returns the seatback frame 54 to the upright position. More specifically, the built-up gas pressure in the aperture 242 of the gas spring 94 is used to move the rear support member 88 toward the first position (corresponding to the upright position of the seatback frame 54) and thereby, returns the seatback frame 54 to the upright position.

In another example of the auto-return feature, the furniture member 50 may include a control. When the user actuates the control (e.g., presses the control), the seatback frame 54 may move automatically from the fully reclined position or one of the intermediate positions to the upright position.

With reference to FIGS. 19-27, another furniture member 350 is provided. The structure and function of the furniture member 350 may be similar or identical to that of the furniture member 50 described above, apart from certain exceptions described below.

Like the furniture member 50, the furniture member 350 may include a seat bottom frame 352, a seatback frame 354, an armrest frame 356, and a reclining mechanism 358. The seatback frame 354 is movable relative to the seat bottom frame 352 between an upright position (FIG. 19) and a fully reclined position (FIG. 20). The structure and function of the seat bottom frame 352, seatback frame 354, and armrest frame 356 may be similar or identical to that of the seat bottom frame 52, the seatback frame 54, and armrest frame 56 described above.

As shown in FIGS. 21-23, the reclining mechanism 358 may include a front support member 386 with a first clevis 404, a rear support member 388 with a second clevis 416, a pair of linkages 374, and a motor-driven linear actuator 560. The structure and function of the front support member 386, rear support member 388, and linkages 374 may be similar or identical to that of the front support member 86, rear support member 88, and linkages 74 described above. While the furniture member 50 depicted in FIGS. 1-18 is manually driven, the furniture member 350 of FIGS. 19-27 is driven by the linear actuator 560 (i.e., the linear actuator 560 drives the seatback frame 354 between the upright and fully reclined positions. Furthermore, the furniture member 350 may not include the release mechanism 90 or the gas spring 94.

The linear actuator 560 may include a first arm 562, a second arm 564, and a motor 566. The second arm 564 may be partially received within the first arm 562 and may be movable relative to the first arm 562 in a telescoping manner. The first arm 562 may be rotatably coupled to the front support member 386 via the first clevis 404 and clevis pin 424. The second arm 564 may be rotatably coupled to the rear support member 388 via the second clevis 416 and clevis pin 424.

The motor 566 may be mounted to the first arm 562. The motor 566 may drivingly engage the second arm 564 to move the second arm 564 relative to the first arm 562. The user may operate the motor 566 via a user interface (not shown) that may include switches, buttons, knobs, etc. to control movement of the seatback frame 354 relative to the seat bottom frame 352 between the upright position (FIGS. 19 and 22) and the fully reclined position (FIGS. 20 and 23). That is, the linear actuator 560 may move between an extended position (FIGS. 24 and 25) corresponding to the upright position and a retracted position (FIG. 26 to 27) corresponding to the fully reclined position. When the seatback frame 354 is in the upright position, the linear actuator 560 is in the extended position. As the seatback frame 354 moves to the fully reclined position, the second arm 564 of the linear actuator 560 slides further into the first arm 562 toward the retracted position.

In some configurations, the components of the furniture member 50 are identical to the components of the furniture member 350, except that the gas spring 94, release mechanism 90, and cable 92 of furniture member 50 can be replaced with the linear actuator 560 to make the powered furniture member 350. Use of common components between the furniture members 50, 350 has the benefit of reducing complexity and cost.

The shape and positioning of the rear support member 88, 388 helps to improve side-to-side rigidity and reduce shaking and vibration in the furniture member 50, 350 as the seatback frame 54 moves relative to the seat bottom frame 52 between the upright and fully reclined positions. Furthermore, attaching the gas spring 94 or the linear actuator 560 to the front and rear support members 86, 386, 88, 388 at positions that are centered along the lengths (i.e., centered between opposing ends) of the front and rear support members 86, 386, 88, 388 also helps to reduce shaking and vibration in the furniture member 50, 350 as the seatback frame 54, 354 moves relative to the seat bottom frame 52, 352.

The rear support member 88, 388 also acts as a lever arm that helps to support the weight of the seatback frame 54, 354 and the force of the occupant's body resting against the seatback frame 54, 354.
