Definitions
- Study carrels are used in shared environments such as classrooms, libraries, and workplaces, and provide partially enclosed workstations to limit distractions and help a user focus on solitary tasks. Often, these environments are multi-use, with both group and independent activities taking place. Therefore, it is desirable to have furniture in these environments which can accommodate both types of activity—tables which allow interactions between users as well as unobstructed lines of site to an instructor or audiovisual presentation, and carrels for independent work or test taking. Examples of furniture from prior art which can transform between these two use cases typically contain multiple moving parts and require multi-step processes to transition between uses.

The first and second partition walls 320 , 330 pass through the first and second slots 222 , respectively, as the carrel assembly 300 transitions between the open and closed positions.
- the convertible carrel 100 comprises a damping device 400 that prevents the carrel assembly 300 from slamming or moving too quickly as it transitions to the open/closed positions while also assisting in the lift of the carrel assembly 300 from the closed position to the open position.
- the damping device 400 is coupled at one end to the rear wall 240 of the desk assembly 200 and at its other end to a lower surface of the stretcher beam 340 of the carrel assembly 300 , thereby allowing the damping device 400 to control the opening and closing of the carrel assembly 300 as described below.
- the damping device 400 is a gas-spring device. More specifically, in the exemplified embodiment the damping device 400 is a gas-spring device of a type known in the art which provides a push-out force and end-damping at both ends of its stroke.
- the gas springs of the damping device 400 will take over and complete the transition to the open position without continued user applied force.
- a user simply pulls on the second desktop 310 and lets the dampening springs of the damping device 400 smoothly drop the second desktop 310 into place in the closed position.
- damping device 400 While a gas spring has been described here as the preferred embodiment of the damping device 400 , the invention is not to be so limited in all embodiments and the damping device 400 may take on other forms, including being one of a rotary damper, a linear damper, one or more latches, or the like. Furthermore, the exact locations of attachment between the damping device 400 and the desk and carrel assemblies 200 , 300 may be modified from that shown, one example of which is shown and described with reference to FIGS. 6 and 7 .
- the damping device 400 helps to push the carrel assembly 300 towards the open position, and then applies a damping force to prevent the carrel assembly 300 from slamming open.
- a user may need to only lift the carrel assembly 300 a few inches upwardly, and then the damping device 400 may take over and fully open the carrel assembly 300 while also applying the damping force at the end of the rotation to prevent slamming.
- the damping device 400 supports the weight of the carrel assembly 300 as it closes, and then applies a damping force to prevent the carrel assembly 300 from slamming closed. That is, a user will pull on the back and let the gravity facilitate the transition of the carrel assembly 300 from the open position to the closed position, with the damping device 400 adding a level of control to the transition and preventing the carrel assembly 300 from slamming into the closed position.
- the damping device 400 is coupled to the rear wall 240 of the desk assembly 200 and to the stretcher beam 340 of the carrel assembly 300 .
- the damping device 400 is in a retracted state (see FIG. 4 ).
- the damping device 400 is in an expanded state (see FIG. 5 ).
- the weight of the carrel assembly 300 applies more force than damping device 400 can lift on its own, therefore the carrel assembly 300 remains in a closed position.
- the push-out force of the damping device 400 begins to take on some of the load and provide assistance in lifting.
- the damping device 400 is able to lift the full weight of the carrel assembly 300 and push it into the fully open position seen in FIG. 5 , where the second desktop 310 of the carrel assembly 300 is at an angle of 90° relative to first desktop 210 of the desk assembly 200 and damping device 400 is fully extended.
- the damping device 400 applies a damping force to counteract its push-out force and prevent the rotating carrel assembly 300 from slamming open with more force than desired.
- the damping device 400 applies a damping force to prevent the rotating carrel assembly 300 from slamming closed with more force than desired.
- FIGS. 6 and 7 an alternative embodiment of a convertible carrel 100 a is illustrated.
- the convertible carrel 100 a is very similar to the convertible carrel 100 and only the differences between the convertible carrel 100 a and the convertible carrel 100 will be described.

- Referring to
FIGS. 1-3 concurrently, aconvertible carrel 100 will be described in accordance with an embodiment of the present invention. Theconvertible carrel 100 generally comprises two assemblies that are coupled together so that one of the assemblies can rotate relative to the other to transition theconvertible carrel 100 between the open and closed positions. In particular, theconvertible carrel 100 generally comprises adesk assembly 200 and acarrel assembly 300. Thedesk assembly 200 is generally stationary as theconvertible carrel 100 is transitioned between the open and closed positions. Thecarrel assembly 300 is the assembly that rotates or moves to transition theconvertible carrel 100 between the open and closed positions.FIG. 1 illustrates the convertible carrel 100 (or thecarrel assembly 300 thereof) in a closed position whereasFIG. 2 illustrates the convertible carrel (or thecarrel assembly 300 thereof) in an open position. - The
desk assembly 200 generally comprises afirst desktop 210, afirst sidewall 220, asecond sidewall 230, and arear wall 240. Thefirst desktop 210 comprises anupper surface 211 and alower surface 212, afront edge 213, arear edge 214, afirst side edge 215, and asecond side edge 216. Thefirst desktop 210 comprises afirst tab 218 located along thefirst side edge 215 and asecond tab 219 located along thesecond side edge 216. Specifically, thefirst tab 218 protrudes somewhat from a remainder of thefirst side edge 215 and thesecond tab 219 protrudes somewhat from a remainder of thesecond side edge 216. The first andsecond tabs front edge 213 of thefirst desktop 210 in the exemplified embodiment. Thedesk assembly 200 may also comprise afront lip 217 which protrudes downwardly from thefirst desktop 210 along thefront edge 213 of thefirst desktop 210. Theupper surface 211 of thefirst desktop 210 forms the working surface of theconvertible carrel 100 when the convertible carrel 100 (or thecarrel assembly 300 thereof) is in the open position, as shown inFIG. 2 . - The
first desktop 210 is coupled to each of the first andsecond sidewalls first desktop 210 may be coupled to each of the first andsecond sidewalls first desktop 210 is coupled to the first andsecond sidewalls first tab 218 abuts against aninner surface 221 of thefirst sidewall 220 and thesecond tab 219 abuts against aninner surface 231 of thesecond sidewall 230. Because thefirst tab 218 sticks out from thefirst side edge 215 of thefirst desktop 210, the remainder of thefirst side edge 215 is spaced apart from theinner surface 221 of thefirst sidewall 220, thereby forming afirst slot 222 between thefirst side edge 215 of thefirst desktop 210 and theinner surface 221 of thefirst sidewall 220. Similarly, because thesecond tab 219 sticks out from thesecond side edge 216 of thefirst desktop 210, the remainder of thesecond side edge 216 is spaced apart from theinner surface 231 of thesecond sidewall 230, thereby forming a second slot between thesecond side edge 216 of thefirst desktop 210 and theinner surface 231 of thesecond sidewall 230. The second slot is not visible in the provided views, but it should be appreciated that the second slot is identical to thefirst slot 222, except it is located on the opposite side of thefirst desktop 210. - While the first and
second slots 222 are formed due to the shape of thefirst desktop 210 in the exemplified embodiment, the invention is not to be so limited in all embodiments. In an alternative embodiment, the slots could be cut-outs formed into thefirst desktop 210 which extend from theupper surface 211 to thelower surface 212. Thus, in some embodiments thedesk assembly 200 comprises the first andsecond slots 222 and they can be formed in various different ways as would be appreciated by persons of ordinary skill in the art. - The
first sidewall 220 comprises theinner surface 221, atop edge 223, abottom edge 224, afront edge 225, and arear edge 226. A firstfront leg 250 is coupled to thefirst sidewall 220 at thefront edge 225 thereof. A firstrear leg 251 is coupled to thefirst sidewall 220 at therear edge 226 thereof. Thefirst sidewall 220 comprises afirst notch 227 formed into the top andrear edges rear leg 251 is aligned with thefirst notch 227 and terminates at the floor of thefirst notch 227, and thus the firstrear leg 251 is shorter than the firstfront leg 250. Thefirst sidewall 220 comprises a recess orpocket 228 formed into theinner surface 221 in a corner thereof that is adjacent to thetop edge 223 and to therear edge 226. That is, therecess 228 is located adjacent to thenotch 227. Stated another way, therecess 228 is in the top rear corner of thefirst sidewall 220. Therecess 228 forms a pocket, but not an aperture, in theinner surface 221 of thefirst sidewall 220 in the exemplified embodiment. It may be possible for therecess 228 to form an aperture or through-hole in other embodiments. - The
second sidewall 230 comprises theinner surface 231, atop edge 233, abottom edge 234, afront edge 235, and arear edge 235. A secondfront leg 252 is coupled to thesecond sidewall 230 at thefront edge 235 thereof. A secondrear leg 253 is coupled to thesecond sidewall 230 at therear edge 236 thereof. Thesecond sidewall 230 comprises asecond notch 237 formed into the top andrear edges rear leg 253 is aligned with thesecond notch 237 and terminates at the floor of thesecond notch 237, and thus the secondrear leg 253 is shorter than the secondfront leg 252. Thesecond sidewall 230 comprises a recess or pocket formed into theinner surface 231 in a corner thereof that is adjacent to thetop edge 233 and to therear edge 236. The recess of thesecond sidewall 230 is located in the top rear corner of thesecond sidewall 230. The recess of thesecond sidewall 230 is not visible in the provided figures, but it should be appreciated that it is positioned in the same position on thesecond sidewall 230 as therecess 228 is positioned along thefirst sidewall 220. While the recess on thesecond sidewall 230 is a pocket in the exemplified embodiment, it could be an aperture or through-hole in other embodiments. - The
rear wall 240 is coupled to and extends between the first andsecond sidewalls rear edges second sidewalls rear wall 240 increases structural rigidity of thedesk assembly 200, but also plays a role in the transitioning of thecarrel assembly 300 between the open and closed positions, as will be described in greater detail below. In the exemplified embodiment, afootrest 260 is coupled to and protrudes from a front surface 241 of therear wall 240. The footrest is also coupled directly to the first andsecond sidewalls desk assembly 200, although this is not required in all embodiments. In fact, thefootrest 260 could be omitted in alternative embodiments. - The
first desktop 210, thefirst sidewall 220, thesecond sidewall 230, and therear wall 240 may be formed from wood, engineered wood, wood laminate, fiberboard, or the like in various different embodiments. The legs 250-253 may be formed from metal such as aluminum, or they may also be formed from the same material as the desktop and sidewalls as noted above. In some embodiments, combinations of wood (real or engineered, and including fiberboard or the like) and metal (such as aluminum) may be used to form the various components of thedesk assembly 200. - Having described the
desk assembly 200, thecarrel assembly 300 will now be described. It should be understood that during use of theconvertible carrel 100, thecarrel assembly 300 rotates or moves while thedesk assembly 200 remains stationary to transition theconvertible carrel 100 between the open and closed positions. Thus, thedesk assembly 200 is intended to be a structurally stable assembly, which is achieved by coupling thefirst desktop 210 to each of the first andsecond sidewalls rear wall 240 to each of the first andsecond sidewalls footrest 260 to the first andsecond sidewalls desk assembly 200. Thecarrel assembly 300 is indirectly coupled to the desk assembly 200 (via a cylindrical member 500) and is configured to rotate relative to thedesk assembly 200, as described in further detail below. - The
carrel assembly 300 generally comprises asecond desktop 310, afirst partition wall 320, and asecond partition wall 330. Thesecond desktop 310 comprises alower surface 311 and anupper surface 312. Theupper surface 312 of thesecond desktop 310 forms the working surface of theconvertible carrel 100 when thecarrel assembly 300 is in the closed position as depicted inFIG. 1 . Thelower surface 311 of thesecond desktop 310 faces the user when thecarrel assembly 300 is in the open position as depicted inFIG. 2 . There arebumpers 315 positioned on thelower surface 311 of thesecond desktop 310 in the exemplified embodiment, which are included to provide cushioning as thecarrel assembly 300 is transitioned from the open position ofFIG. 2 to the closed position ofFIG. 1 . Thus, thebumpers 315 may prevent abrasion from marring of thelower surface 311 of thesecond desktop 310 while it is closed. Of course, thebumpers 315 may be omitted or positioned at other locations along thesecond desktop 310 or even along the tops of thefront legs top edges second sidewalls - The first and
second partition walls lower surface 311 of thesecond desktop 310. The first andsecond partition walls second partition walls upper edge portions lower edge portions rounded edge portions lower edge portions lower edge portions first partition wall 320 meet or intersect at a corner that is adjacent to thesecond desktop 310. The upper andlower edges second partition wall 320 meet or intersect at a corner that is adjacent to thesecond desktop 310. Theupper edge portions lower surface 311 of thesecond desktop 310. In the exemplified embodiment, the first andsecond partition walls second desktop 310 using mortise and tenon joints along with adhesive such as wood glue. However, the invention is not to be so limited in all embodiments and the first andsecond partition walls second desktop 310 using other techniques, including other styles of joints, and/or fasteners such as cam fasteners, screws, nails, or the like. Thesecond desktop 310 comprises afront edge 313, afirst side edge 314, and asecond side edge 315. - The
first partition wall 320 is positioned adjacent to thefirst side edge 314 of thesecond desktop 310 and thesecond partition wall 330 is positioned adjacent to thesecond side edge 315 of thesecond desktop 310. However, in the exemplified embodiment thefirst partition wall 320 is set slightly inward of thefirst side edge 314 and thesecond partition wall 330 is set slightly inward of thesecond side edge 315. The exact positioning of the first andsecond partition walls second desktop 310 should not be limiting of the invention unless specifically claimed as such. However, it is preferable that the first andsecond partition walls first desktop 210 when thecarrel assembly 300 is in the open position. - The
first partition wall 320 comprises afirst hole 325 that extends through the thickness of the first partition wall 320 (i.e., between inner and outer surfaces) in a position adjacent to the intersection between the upper andlower edge portions lower edge portions first partition wall 320 intersect at a corner (which may be a rounded corner or a sharp corner), and thefirst hole 325 is positioned adjacent to that corner. Similarly, thesecond partition wall 330 comprises asecond hole 335 that extends through the thickness of the second partition wall 330 (i.e., between inner and outer surfaces) in a position adjacent to the intersection between the upper andlower edge portions lower edge portions second partition wall 330 intersect at a corner (which may be a rounded corner or a sharp corner), and thesecond hole 335 is positioned adjacent to that corner. The first andsecond holes second partition walls lower surface 311 of thesecond desktop 310. - The
carrel assembly 300 further comprises astretcher beam 340 which is affixed to the inner surfaces of each of the first andsecond partition walls stretcher beam 340 is coupled to and extends between the first andsecond partition walls stretcher beam 340 is coupled to the first andsecond partition walls lower edge portions rounded edge portions second desktop 310. Thestretcher beam 340 is positioned below/beneath thefirst desktop 210 of thedesk assembly 200 when thecarrel assembly 300 is in both its open and closed positions. Thestretcher beam 340 provides some structural rigidity to thecarrel assembly 300 by affixing the twopartition walls carrel assembly 300 as described in more detail below with reference toFIGS. 4 and 5 . That is, a dampingdevice 400 is coupled to therear wall 240 of thedesk assembly 200 and to thestretcher beam 340 of thecarrel assembly 300, which is barely visible inFIG. 3 and more visible inFIGS. 4 and 5 . In the exemplified embodiment, thestretcher beam 340 is coupled to each of the first andsecond partition walls stretcher beam 340 could be coupled to the first andsecond partition walls - The
convertible carrel 100 further comprises acylindrical member 500 around which thecarrel assembly 300 rotates when transitioning between the open and closed positions. Thecylindrical member 500 may be a hollow tubular member, or it may be a solid member. Furthermore, thecylindrical member 500 may be formed out of metal, such as aluminum, although the invention is not to be so limited in all embodiments. Thecylindrical member 500 comprises afirst end 501 which nests within therecess 228 in theinner surface 221 of thefirst sidewall 220 of thedesk assembly 200 and asecond end 502 which nests within the recess (not visible) in theinner surface 231 of thesecond sidewall 230 of thedesk assembly 200. Thus, thecylindrical member 500 is held in place between the first andsecond sidewalls rear edge 214 of thefirst desktop 210 of thedesk assembly 200 may also be affixed directly to thecylindrical member 500 using fasteners, such as screws. InFIG. 4 there are holes illustrated in thecylindrical member 500 where screws (e.g., woodscrews) can be inserted for attaching therear edge 214 of thefirst desktop 210 to thecylindrical member 500. Thecylindrical member 500 is of a length that allows it to nest within therecesses 228 in the first andsecond sidewalls second sidewalls cylindrical member 500 is held securely in position between the first andsecond sidewalls cylindrical member 500 may be coupled to the first andsecond sidewalls - The
cylindrical member 500 also extends through the first andsecond holes second partition walls carrel assembly 300. Thus, thecylindrical member 500 indirectly couples thecarrel assembly 300 to thedesk assembly 200. The longitudinal axis of thecylindrical member 500 forms the rotational axis of thecarrel assembly 300 as thecarrel assembly 300 transitions between the open and closed positions. That is, because thecylindrical member 500 is fixed in place by being sandwiched between the first andsecond sidewalls desk assembly 200 and being fixedly coupled to thefirst desktop 210 of thedesk assembly 200, thecarrel assembly 300 can rotate around thecylindrical member 500. - Finally, the
convertible carrel 100 comprises a first flanged bushing 510 and a secondflanged bushing 520. The first flanged bushing 510 comprises a first flange portion 511 and the secondflanged bushing 520 comprises asecond flange portion 521. The first flanged bushing 510 is positioned within thefirst hole 325 in thefirst partition wall 320 so as to surround a portion of thecylindrical member 500. The secondflanged bushing 520 is positioned within thesecond hole 335 in thesecond partition wall 330 so as to surround a portion of thecylindrical member 500. Moreover, when theconvertible carrel 100 is fully assembled, the first flange portion 511 is sandwiched between thefirst partition wall 320 of thecarrel assembly 300 and thefirst sidewall 220 of thedesk assembly 200. Similarly, thesecond flange portion 521 is sandwiched between thesecond partition wall 330 of thecarrel assembly 300 and thesecond sidewall 230 of thedesk assembly 200. Theflange portions 511, 521 of the first and secondflanged bushings 510, 520 keep the first andsecond sidewalls desk assembly 200 spaced away from the first andsecond partition walls carrel assembly 300 in order to prevent them from touching and rubbing against each other during the transitioning of thecarrel assembly 300 between the open and closed positions. - Each of the first and second
flanged bushings 510, 520 is formed from a self-lubricating material to reduce friction as thecarrel assembly 300 is rotated as described herein. One example of such a self-lubricating material is iglide® G300 made by igus®. However, the invention is not to be limited to this specific material and the first and secondflanged bushings 510, 520 may be made from other known self-lubricating materials in other embodiments. - Due to the arrangement of the various components described herein, the
carrel assembly 300 is configured to rotate about a rotational axis A-A which is coincident with the longitudinal axis of thecylindrical member 500. In particular, when thecarrel assembly 300 is in the closed position as shown inFIG. 1 , a user may apply an upward force onto thefront edge 313 of thesecond desktop 310 of thecarrel assembly 300 to cause thecarrel assembly 300 to rotate about the rotational axis A-A and transition into the open state. Similarly, when thecarrel assembly 300 is in the open position as shown inFIG. 2 , a user may apply a downward rotational force onto thesecond desktop 310 of thecarrel assembly 300 to cause thecarrel assembly 300 to rotate about the rotational axis A-A and transition into the closed state. - When the
carrel assembly 300 is in the open position (FIG. 2 ), a rear portion of thesecond desktop 310 of thecarrel assembly 300 nests within thenotches second sidewalls desk assembly 200, as best shown inFIG. 2 . Thus, thenotches second sidewalls desk assembly 200 are configured to receive the portion ofsecond desktop 310 of thecarrel assembly 300 which extends past the pivot point when thecarrel assembly 300 is rotated into the open position. Thus, thenotches second desktop 310 and the wall. - When the
carrel assembly 300 is in the open position, thesecond desktop 310 extends vertically upward relative to thefirst desktop 210 adjacent to therear edge 214 of the first desktop. Furthermore, the first andsecond partition walls top edges second sidewalls desk assembly 200. The first andsecond partition walls second sidewalls second sidewalls second desktop 310 and the first andsecond partition walls carrel assembly 300 is in the open position. Furthermore, in this position thefirst desktop 210 of thedesk assembly 200 forms the working surface of theconvertible carrel 100 upon which a user can place items such as a laptop, papers, books, or the like. Furthermore, when thecarrel assembly 300 is in the open position, a lower edge portion of thefirst partition wall 320 is located within thefirst slot 222 and a lower edge portion of thesecond partition wall 330 is located within the second slot. By always keeping a part of thepartition walls slots 222, there is no concern that the first andsecond partition walls slots 222, which could cause an issue for a user trying to transition thecarrel assembly 300 from the open position to the closed position. - When the
carrel assembly 300 is in the closed position (FIG. 1 ), thesecond desktop 310 extends across and covers thefirst desktop 210 of thedesk assembly 200. However, thesecond desktop 310 is maintained spaced apart from thefirst desktop 210 because thelower surface 311 of thesecond desktop 310 rests atop of thetop edges second sidewalls upper surface 211 of thefirst desktop 210 of thedesk assembly 200. This prevents scratching of the first andsecond desktops carrel assembly 300 is in the closed position. Thus, thesecond desktop 310 is not in surface contact with thefirst desktop 210 even when thecarrel assembly 300 is in the closed position. When thecarrel assembly 300 is in the closed position, theupper surface 312 of thesecond desktop 310 is exposed and forms the working surface of theconvertible carrel 100 upon which a user's papers, computer, or other items may be placed. - Furthermore, when the
carrel assembly 300 is in the closed position, the first andsecond partition walls second desktop 310 adjacent to the inner surfaces of the first andsecond sidewalls desk assembly 200. That is, the first andsecond partition walls top surfaces second sidewalls desk assembly 200 when thecarrel assembly 300 is in the closed position. Rather, the first andsecond partition walls second sidewalls desk assembly 200. Moreover, when thecarrel assembly 300 is in the closed position, an upper edge portion of the first andsecond partition walls second slots 222, respectively. That is, because the first andsecond desktops second partition walls lower surface 311 of thesecond desktop 310, a portion of the first andsecond partition walls second slots 222. The first andsecond partition walls second slots 222, respectively, as thecarrel assembly 300 transitions between the open and closed positions. - Referring to
FIGS. 4 and 5 , theconvertible carrel 100 comprises a dampingdevice 400 that prevents thecarrel assembly 300 from slamming or moving too quickly as it transitions to the open/closed positions while also assisting in the lift of thecarrel assembly 300 from the closed position to the open position. The dampingdevice 400 is coupled at one end to therear wall 240 of thedesk assembly 200 and at its other end to a lower surface of thestretcher beam 340 of thecarrel assembly 300, thereby allowing the dampingdevice 400 to control the opening and closing of thecarrel assembly 300 as described below. - In the exemplified embodiment, the damping
device 400 is a gas-spring device. More specifically, in the exemplified embodiment the dampingdevice 400 is a gas-spring device of a type known in the art which provides a push-out force and end-damping at both ends of its stroke. Thus, during transition from the closed position to the open position, after lifting thesecond desktop 310 a few inches, the gas springs of the dampingdevice 400 will take over and complete the transition to the open position without continued user applied force. Furthermore, during transitioning from the open position to the closed position, a user simply pulls on thesecond desktop 310 and lets the dampening springs of the dampingdevice 400 smoothly drop thesecond desktop 310 into place in the closed position. While a gas spring has been described here as the preferred embodiment of the dampingdevice 400, the invention is not to be so limited in all embodiments and the dampingdevice 400 may take on other forms, including being one of a rotary damper, a linear damper, one or more latches, or the like. Furthermore, the exact locations of attachment between the dampingdevice 400 and the desk andcarrel assemblies FIGS. 6 and 7 . - Due to the existence of the damping
device 400, as thecarrel assembly 300 transitions from closed to open, the dampingdevice 400 helps to push thecarrel assembly 300 towards the open position, and then applies a damping force to prevent thecarrel assembly 300 from slamming open. Thus, a user may need to only lift thecarrel assembly 300 a few inches upwardly, and then the dampingdevice 400 may take over and fully open thecarrel assembly 300 while also applying the damping force at the end of the rotation to prevent slamming. Similarly, when thecarrel assembly 300 transitions from open to closed, the dampingdevice 400 supports the weight of thecarrel assembly 300 as it closes, and then applies a damping force to prevent thecarrel assembly 300 from slamming closed. That is, a user will pull on the back and let the gravity facilitate the transition of thecarrel assembly 300 from the open position to the closed position, with the dampingdevice 400 adding a level of control to the transition and preventing thecarrel assembly 300 from slamming into the closed position. - As mentioned above, the damping
device 400 is coupled to therear wall 240 of thedesk assembly 200 and to thestretcher beam 340 of thecarrel assembly 300. When thecarrel assembly 300 is in the closed position, the dampingdevice 400 is in a retracted state (seeFIG. 4 ). When thecarrel assembly 300 is in the open position, the dampingdevice 400 is in an expanded state (seeFIG. 5 ). - In the closed position, the weight of the
carrel assembly 300 applies more force than dampingdevice 400 can lift on its own, therefore thecarrel assembly 300 remains in a closed position. As the user lifts thefront edge 313 of thesecond desktop 310 of thecarrel assembly 300, the push-out force of the dampingdevice 400 begins to take on some of the load and provide assistance in lifting. When thesecond desktop 310 of thecarrel assembly 300 reaches an angle of approximately 30° relative tofirst desktop 210 of thedesk assembly 200, the dampingdevice 400 is able to lift the full weight of thecarrel assembly 300 and push it into the fully open position seen inFIG. 5 , where thesecond desktop 310 of thecarrel assembly 300 is at an angle of 90° relative tofirst desktop 210 of thedesk assembly 200 and dampingdevice 400 is fully extended. - During the action of opening, when the
second desktop 310 reaches an angle of approximately 75° relative tofirst desktop 210, the dampingdevice 400 applies a damping force to counteract its push-out force and prevent therotating carrel assembly 300 from slamming open with more force than desired. Similarly, during the action of closing, when thesecond desktop 310 is it an angle of approximately 30° relative tofirst desktop 210, the dampingdevice 400 applies a damping force to prevent therotating carrel assembly 300 from slamming closed with more force than desired. - Referring to
FIGS. 6 and 7 , an alternative embodiment of aconvertible carrel 100 a is illustrated. Theconvertible carrel 100 a is very similar to theconvertible carrel 100 and only the differences between theconvertible carrel 100 a and theconvertible carrel 100 will be described. It should be appreciated that for all other features of theconvertible carrel 100 a, the description above is applicable. - The
convertible carrel 100 a comprises adesk assembly 200 a and acarrel assembly 300 a that are coupled together in much the same way as those same components of theconvertible carrel 100. Thedesk assembly 200 a comprises afirst desktop 210 a, arear wall 240 a, first andsecond sidewalls 220 a (only the first sidewall is visible in the provided view),legs 250 a, and afootrest 260 a. Thecarrel assembly 300 a comprises asecond desktop 310 a, afirst partition wall 320 a, and a second partition wall (not shown in the view provided, but identical to thesecond partition wall 330 of thecarrel assembly 300 described above). The desk andcarrel assemblies carrel assemblies - The
carrel assembly 300 a comprises a stretcher beam 340 a that extends between the first andsecond partition walls 320 a. However, the stretcher beam 340 a is positioned more rearward along the first andsecond partition walls 320 a than with the prior described embodiment. Theconvertible carrel 100 a comprises a dampingdevice 400 a that operates the same as the dampingdevice 400 described above. The description of the dampingdevice 400 described above is applicable to the dampingdevice 400 a, except for the attachment location. That is, the dampingdevice 400 a is coupled to therear wall 240 a of thedesk assembly 200 a at one end and to thefirst partition wall 320 a of thecarrel assembly 300 a at its opposite end. Thus, rather than being coupled to the stretcher beam 340 a as with the prior embodiment, the dampingdevice 400 a is coupled to thefirst partition wall 320 a. Moreover, while only a single dampingdevice 400 a is shown in the provided views, there may be multiple dampingdevices 400 a such that one dampingdevice 400 a is coupled to therear wall 240 a of thedesk assembly 200 a and to thefirst partition wall 320 a of thecarrel assembly 300 a and another damping device (not visible) is coupled to therear wall 240 a of thedesk assembly 200 a and to the second partition wall (not visible) of thecarrel assembly 300 a. The dampingdevice 400 a is coupled to thefirst partition wall 320 a along alower edge portion 322 a thereof, which is the portion that remains below thefirst desktop 210 a of thedesktop assembly 200 a in both the open and closed positions. - In this embodiment, there is also a
linear damper 410 a that is coupled to the first andsecond partition walls 320 a (as noted above, only thefirst partition wall 320 a is visible in the provided views, but an identical linear damper may be located on the second partition wall as well). Thelinear damper 410 a may be embedded in an edge of thefirst partition wall 320a located along thelower edge portion 322 a thereof. In the exemplified embodiment, thelinear damper 410 a is located behind the bracket that attaches the dampingdevice 400 a to thefirst partition wall 310 a. Thelinear damper 410 a serves a similar function to the damping device 400 (or the damper built into the gas spring), by adding a supplementary force to improve the soft close action of thecarrel assembly 300 a as it transitions from the open position to the closed position. In particular, as thecarrel assembly 300 a transitions to the closed position, thelinear damper 410 a contacts therear wall 240 a of thedesk assembly 200 a and provides a small amount of resistance as thelinear damper 410 a is compressed. This further slows the movement of thecarrel assembly 300 a and prevents thecarrel assembly 300 a from slamming as it transitions into the closed position. Depending on the length of thelinear damper 410 a, thelinear damper 410 a may only engage therear wall 240 a during the last 5°-10° of rotation of thecarrel assembly 300 a. - Other than the different connection location for the damping
device 400 a, the addition of a duplicative damping device, the addition of the one or morelinear dampers 410 a, and the location of thestretcher beam 340, theconvertible carrel 100 a is identical to theconvertible carrel 100 and the discussion of theconvertible carrel 100 provided above is applicable to theconvertible carrel 100 a. -
FIGS. 8 and 9 illustrate aconvertible carrel assembly 600 which is a single unit with adesk assembly 610 and tworotating carrel assemblies desk assembly 610 independently of one another.FIG. 8 illustrates the tworotating carrel assemblies FIG. 9 illustrates the tworotating carrel assemblies rotating carrel assemblies rotating carrel assemblies desk assembly 610 to enable it to accommodate two distinct and independently rotatingcarrel assemblies desk assembly 610 are shared among the tworotating carrel assemblies desk assembly 610 comprises a singularrear wall 640, afirst sidewall 611, and asecond sidewall 612 that are shared between the twocarrel assemblies second sidewalls convertible carrel assembly 600. Thedesk assembly 610 comprises two separate lower desktops, one aligned with each of the twoindependent carrel assemblies lower desktops 615 is visible inFIG. 9 and the other is not visible in the provided view, but its structure and features should be readily understood from the full description set forth herein. - The
carrel assembly 620 comprises a firstupper desktop 621 and first andsecond partition walls carrel assembly 630 comprises a secondupper desktop 631 and first andsecond partition walls carrel assemblies carrel assembly 300 described above, and thus thecarrel assemblies carrel assemblies singular desk assembly 610 using the cylindrical members as described above. The difference is that in this embodiment there are two cylindrical members, one for eachrotating carrel assembly first sidewall 611 comprises a first notch (not visible, but identical the second notch in both size and location) and thesecond sidewall 612 comprises anotch 613. Thenotch 613 is wider than the notch of the prior described embodiments because it is designed or configured to receive thesecond desktops second carrel assemblies FIG. 9 . - The other features of the
convertible carrel 100 as described above are also applicable to this embodiment, including the inclusion of the damping device, the slots, the footrest, the stretcher beam, the cylindrical member, and the like. Each of thecarrel assemblies rear wall 640 via a distinct damping device. In particular, thecarrel assembly 620 may be coupled to a first surface of therear wall 640 with a damping device which extends between a stretcher beam of thecarrel assembly 620 and the first surface of therear wall 640. Similarly, thecarrel assembly 630 may be coupled to a second surface of therear wall 640 with a damping device which extends between a stretcher beam of thecarrel assembly 630 and the second surface of therear wall 640. - A typical use case is illustrated in
FIG. 10 , showing multiple of theconvertible carrel assemblies 600 ofFIGS. 8 and 9 (also referred to as double-carrel units) coupled together to create a large table when all carrel assemblies are closed.FIG. 11 shows the same attachedconvertible carrel assemblies 600 with all carrels open. It should be noted that any one of the carrel units can be opened or closed at any given time, independent of the others. - As used throughout, ranges are used as shorthand for describing each and every value that is within the range.
