The outer surface of the engaging member 368 can form a rounded shape or a partially cylindrical shape. As shown in FIGS. 10A and 17, the inner portion of the curved member 369 may have a plurality of ribs 374 connecting the first end 370 or the C-shaped member 362 to the straight member 371. The rib 374 can extend parallel to the direction of the longitudinal axis 376 of the engaging member 368, but other orientations and combinations of orientations are possible. The plurality of ribs 374 can increase the strength of the clamp member 360 in order to withstand the forces exerted by repeated attachment and detachment. The outer shape of the clamp member 360 can be symmetrical about the horizontal plane extending through the longitudinal axis 376 of the engaging member 368. 11 and 12 show another feature of the cup holder assembly 300 for easier transport of the portable chair 100 when it is in the folding configuration. When attached to the portable chair 100, the cup holder assembly 300 is shown in FIG. 11 from the outer position where the cup holder 310 is positioned outside the profile of the front legs 112A, 112B, as shown in FIG. The holder 310 can rotate to an inner position positioned inside the profile of the front legs 112A, 112B. The cup holder assembly 300 is still connected to one of the front legs 112A, 112B of the portable chair 100 and can rotate from the outer position to the inner position.

13A-13C show a method of rotating the cup holder assembly 300 from the outer position to the inner position when the portable chair 100 is in the folding configuration. As shown in FIG. 13A, the cup holder assembly 300 is in the outer position. During the next step, as shown in FIG. 13B, the user clamps the cup holder assembly 300 along any one of the front legs 112A, 112B to which the cup holder assembly 300 is attached outward from the respective bushings 173A or 173B. The 360 C-shaped member 362 can be slid. Once the lower surface 366 is above the respective bushings 173A or 173B, the user can then rotate the C-shaped member around the front legs 112A, 112B while the clamp member 360 is still attached. .. Finally, as shown in FIG. 13C, the user completes the rotation of the cup holder assembly 300 to the inner position where the cup holder 310 is positioned inside the profile of the front legs 112A, 112B.

As described above, the cup holder assembly 300 can be releasably connected to either the front legs 112A or 112B. To move the cup holder assembly 300 from one side to the other side of the portable chair 100, the cup holder 310 is used to ensure that the cup holder 310 is in the proper beverage holding direction for the user. As shown in FIGS. 14A to 14C, it can rotate with respect to the clamp member 360. At least in the above exemplary embodiment, the longitudinal axis of the C-shaped member 362 is neither parallel nor perpendicular to the longitudinal axis of the cylindrical wall 314 of the cup holder 310, resulting in the two axes being constant with each other. Positioned at an angle. To rotate the cup holder 310 with respect to the clamp member 360, the user can pull the cup holder 310 and collar 340 outward from the clamp member 360. The collar 340 and the cup holder 310 are then used to disengage the set of rotation restraints 341 and 376 on the collar 340 and engaging member 368 shown in FIGS. 16B, 17 and 18A-18B, respectively. A predetermined distance can be slid along the longitudinal axis 376 of the engaging member 368. Once the cup holder 310 and collar 340 have been moved a predetermined distance, both the collar 340 and the cup holder 310 can be rotated to the desired position for use on opposite sides of the chair 100. For example, as shown in FIGS. 14A-14C, the cup holder 310 is a clamp member as the collar 340 slides backward toward the clamp member 360 shown in FIG. 14C from its initial position shown in FIG. 14A. It can rotate about a certain amount with respect to 360, or can rotate until the rotation suppression mechanisms 341 and 376 engage with each other. The cup holder 310 can rotate from a first position to a second position, with the first and second positions separated by about 144 degrees. Alternatively, the first and second positions are within the range of 130-150 degree separation, or within the range of 120-160 degree separation, or within the range of 110-170 degree separation. There may be. Alternatively, the first and second positions are within a range of 5 to 15 degrees, or within a range of 15 to 30 degrees, or within a range of 30 to 90 degrees. May be separated by. The rotation restraint mechanisms 341 and 637, when attached to either the left or right hand side of the chair 100, in predetermined positions that allow the bottom of the cup holder 310 to be parallel to the ground, the collar 340 and The cup holder 310 can be set to be fixed to the clamp member 360. An exemplary embodiment shows two predetermined positions of the cup holder 310 with respect to the clamp member 360, but the number of predetermined positions may be any number, such as three, four, or five or more. There may be. Optionally, the user can rotate the cup holder 310 to any location with respect to the clamp member 360 within a predetermined range of motion. Alternatively, the cup holder 310 can rotate freely over 360 degrees with respect to the collar 340.

Each of the cup holder 310, collar 340, and clamp member 360 can have a alignment index 396 to assist the user in aligning the cup holder 310 and collar 340 in the proper position. The position alignment index 394 can include a portion that is positioned on each of the engaging member 318 of the cup holder 310 and the outer surface of the collar 340. The position alignment index 394 can be position-aligned with one of the two corresponding position alignment indexes 396 positioned on the clamp member 360. When the alignment indicators 394 and 396 are on the same line, the collar 340 and the clamp member 360 are properly aligned so that the cup holder assembly 300 is in one of the predetermined optimal operating positions. .. Position matching indicators 394, 396 are raised surfaces, recesses, or other contrasting mechanisms that allow the user to easily identify a predetermined optimal operating position for the cup holder assembly 300. You may.

As shown in FIGS. 16B, 18A, and 18B, the plurality of rotation suppression mechanisms 341 on the collar 340 may include a plurality of bosses 341 rotatably spaced around the central axis of the collar 340. Each of the plurality of bosses 341 can engage with the corresponding rotation suppression mechanism 367 of the clamp member 360 shown in FIGS. 16B and 17. The plurality of rotation restraint mechanisms 367 on the clamp member 360 may include a plurality of pockets sized to accommodate the boss 341 of the collar 340. Each of the plurality of bosses 341 and the plurality of pockets 367 can have a substantially rectangular shape. The pocket 367 can include only the side walls and may not have a back surface to allow bosses with multiple lengths to be accommodated. The number of pockets 367 on the clamp member 360 can be greater than the number of bosses 341 on the collar 340 to allow the collar 340 to rotate in multiple directions with respect to the clamp member 360. For example, as shown in the exemplary embodiments of FIGS. 16B, 17, 18A, and 18B, the number of bosses 341 is 3, while the number of pockets is 4. This configuration allows the collar to rotate with respect to the clamp member 360 so that at least three rotation restraints are still engaged with the clamp member 360 when the cup holder 310 is in the working position. ..

In addition, at least one of the rotation suppression mechanisms on the collar can limit the maximum permissible rotation in order to determine the range of rotation of the collar 340 with respect to the clamp member 360. For example, one of the plurality of bosses 341, the boss 341A, can have a longer length than the other bosses 341, so that the user disengages the plurality of bosses 341 from the plurality of pockets 367. By pulling the collar 340 from the clamp member 360 by a predetermined distance for this, the longer length of the boss 341A can prevent the collar 340 from rotating beyond the maximum permissible rotation. The collar 340 can rotate until the boss 341A collides with one of the two side surfaces 367A forming at least two portions of the plurality of pockets 367 on the clamp member 360. The surface 367A can also extend longer than the sides of the other pockets closer to the second end 372 of the engaging member 368. The side surface 367A can form a stopper for the boss 341A to control the amount of rotation of the collar 340 with respect to the clamp member 360 and efficiently set the optimum operating position of the cup holder 310 with respect to the clamp member 360. In an exemplary embodiment, the maximum permissible rotation may be about 144 degrees, provided that it may be at any given angle.

When the cup holder 310 is rotated to the new position, the user separates the C-shaped member 362 of the cup holder assembly 300 from the first front legs 112A, 112B and separates the C-shaped member 362 from the first front leg 112A, 112B. It can be reattached to the front legs 112B and 112A of 2. The C-shaped member 362 can have a plurality of raised portions 386 capable of increasing the holding force of the C-shaped member 362 with respect to the front legs 112A and 112B. The plurality of raised portions 386 can extend in the longitudinal direction between the upper surface 364 and the lower surface 366 within the C-shaped member 362. Further, the plurality of raised portions 386 can be evenly spaced within the C-shaped member 362. Alternatively, the plurality of raised portions 386 may be unevenly spaced so that there are more raised portions 386 near the open end in the C-shaped member 362. The plurality of raised portions 386 can be integrally formed with the C-shaped member 362. Optionally, or optionally, the plurality of ridges 386 may have a coating to improve their retention. The C-shaped member 362 may require a force of 25-40 Newtons (N) to be applied towards the closed end of the C-shaped member in order to engage the clamp member 360 with the front legs 112A, 112B.

15A and 15B show a cross-sectional view of the connection between the engaging member 368 of the clamp member 360, the collar 340, and the cup holder 310 along the longitudinal axis 376. The engaging member 318 can have an outer surface 320 and an inner cavity 322 that generally follows the shape of the outer surface 320. For example, exemplary embodiments such as those shown in FIGS. 8A and 18 have a substantially cylindrical outer surface 320, which may have any shape. Within the inner cavity 322, a plurality of flex fingers 324 can extend inward from the inner surface 326. Each flex finger 324 can have a tapered member 328. Multiple flex fingers 324 can be separated from each other and have different sizes.

As shown in FIGS. 15-19, the collar 340 can have a first end 342 with a plurality of corresponding flex fingers 344 that engage the flex fingers 324 of the cup holder 310. A snap engagement is provided to secure the collar 340 to the cup holder 310. The plurality of flex fingers 344 on the collar 340 may have a portion extending along the longitudinal axis and a portion having a taper. The flex fingers 344 can be separated from each other, similar to the flex fingers 324 on the cup holder 310. The collar 340 can also include a plurality of alignment members 352 positioned between the flex fingers 344, as shown in FIGS. 16 and 17. Each alignment member 352 is placed on the cup holder 310 to prevent the cup holder 310 from rotating relative to the collar 340 and to ensure that the cup holder 310 is properly secured to the collar 340. A pair of radially extending flanges 353 can be provided that can contact at least one of the ends of the flex finger 324. Therefore, the cup holder 310 can be secured to the collar 340 in only one orientation to prevent the components from being erroneously assembled. Each of the plurality of flex fingers 324 and 344 can include two flex fingers 324 and 344, but may include three or more flex fingers. For example, the flex fingers 324 and 344 are positioned within the upper portion of the engaging member 318 and the upper portion of the collar 340, respectively, and the lower portion of the engaging member 318 and below the collar 340, respectively. It can include a lower flex finger that is positioned within the side portion. Flex fingers 324 and 344 can have different sizes so that one flex finger is larger than the other. For example, as shown in an exemplary embodiment, the lower flex fingerer extends around a larger diameter portion of the collar 340 than the upper flex fingerer, so that the lower flex fingerer is an upper flex finger. Larger than finger.

By adjusting the stiffness of the flex finger 344, the connection of the cup holder 310 to the collar 340 is a cup under normal use where the bottle or other device is inserted into the cup holder 310 and removed from the cup holder. Although the holder 310 can be supported, the flex fingers 324 and flex fingers 344 on the cup holder 310 will be applied to the cup holder 310 when a greater force than normally found during use is applied to the cup holder 310. The flex fingers 324 and 344 can be disengaged from each other and adjusted to allow the cup holder 310 to disengage from the collar 340. For example, if a force greater than 100 Newton (N) is applied to the cup holder 310 in the vertical direction, the cup holder 310 will be released from the collar 340, or instead, 115 Newton (N). If a force of more than, more than 130 Newtons (N), or even more than 145 Newtons (N) is applied to the cup holder 310, the cup holder 310 will be released from the collar 340. Since this disengagement force is applied in the vertical direction, this force creates a moment around the C-shaped member 362. However, since the disengagement force and the moment are directed in different directions with respect to the clamp-on force, the clamp member 360 can remain fixed to the chair 100. The disengagement of the cup holder 310 from the collar 340 allows the collar 340 and the clamp member 360 to remain undamaged and unaffected by any sustained damage. Therefore, the cup holder 310 can be reattached to the collar 340 and ready for reuse.

As mentioned above, a feature of the cup holder assembly 300 is that the collar 340 and the cup holder 310 can rotate with respect to the clamp member 360. To allow this rotation, the collar 340 slidably and rotatably engages the clamp member 360 at the second end 346 that connects to the second end 372 of the engagement member 368 of the clamp member 360. can do. As shown in FIG. 15B, in order to rotate the collar 340 with respect to the clamp member 360, the user can apply a force to pull the collar 340 outward from the clamp member 360. By pulling the collar 340 outward from the clamp member 360, the set of rotation restraint mechanisms 341 and 376 of the collar 340 and the clamp member 360 is disengaged, and the collar 340 and the cup holder 310 with respect to the clamp member 360. It becomes possible to rotate. The rotation restraint mechanisms 341 and 637 prevent any unwanted or accidental rotation between the collar 340 and the clamp member 360 when the cup holder 310 is in place. As mentioned above, in one embodiment, the cup holder 310 can rotate from a first position to a second position, with the first and second positions separated by about 144 degrees. There is.

The collar 340 can be permanently fixed to the clamp member 360. The collar 340 can have a central protrusion 345 extending opposite to the first end 342 of the collar 340. The central protrusion 345 can extend into the opening 382 of the clamp member 360. The collar 340 is then clamped using a fixing member 390 that extends through the opening 382 of the clamp member 360 and through the opening 350 that extends from the first end 342 through the second end 346 through the collar 340. It can be fixed to the member 360. The openings 350 and 382 can be extended through the center of the collar 340 and the center of the engaging member 368 of the clamp member 360, respectively. In addition, the collar 340 can be fixed to the clamp member 360 by a spring 392 positioned within the opening 350 of the protrusion 345 that is fixed to the clamp member 360 by the fixing member 390. Until the user overcomes the spring force and slides the collar 340 outward from the clamp member 360 along the fixing member 390 and applies a reaction force large enough to disengage the rotation restraint mechanisms 341 and 376. The spring 392 exerts a force on the collar 340 to keep the joint surface 348 in contact with the mounting surface 378 of the clamp member 360. The protrusion 345 can remain partially extended into the opening 382 even while the rotation restraint mechanisms 341 and 376 are disengaged. The collar 340 can be slidably moved by a predetermined distance that can be controlled by the length of the fixing member 390. The engaging member 368 can also have a shelf 384 extending around the periphery of the second end 372. The fixing member 390 may be a mechanical fastener such as a rivet, where the rivet joins the collar 340 to the clamp member 360, or alternative, the fixing member 390 is the collar 340 and the clamp member It may be a screw that can be fixed by a nut that fixes 360.
