Description

Technical Field

[0001] The present disclosure relates generally to high chairs and, more particularly, to convertible high chairs. Background Art

[0002] High chairs are commonly used by parents every day to provide a seat for children to eat at. Typically, a high chair includes a rigid seat portion supported above the floor by a frame or bracket. The seat is usually located at a height above the floor, such as with a frame or bracket so that children can sit at the height of a conventional table while eating their meals. Sometimes, a high chair includes a footrest supported by a bracket located below the seat portion, on which the child can rest his feet when sitting on the seat.

[0003] Many times, when children are seated and secured in a typical high chair at mealtime, they become uncomfortable, fidgety or fussy because they are unable to stand up, reach or stretch their bodies.

[0097] This article describes a sit-to-stand convertible high chair. Figure 1 and Figure 2 The sit-to-stand convertible high chair 10 includes a frame 12 and a foot platform 16, wherein the frame 12 is configured to support the high chair 10 above the floor, and the foot platform 16 is adjustably mounted on the frame 12. The high chair 10 also includes a seat assembly 14, which is adjustably mounted on the frame 12 above the foot platform 16. The frame 12 may include pillars 13 and a base 15. The base 15 can provide a stable support for the high chair 10 on the floor, and the pillars 13 are configured to extend vertically upward from the base 15 at a certain angle relative to the base 15, for supporting the seat assembly 14 and the foot platform 16 above the floor. The seat assembly 14 includes a support surface 18 and a backrest 20. The support surface 18 is movable to enable the sit-to-stand convertible high chair 10 to be in a seated configuration ( Figure 1 ) and standing configuration ( Figure 2 ) and in the seated configuration ( Figure 1 ), the support surface 18 is configured to support a user (child) in a sitting position in the high chair 10, and in a standing configuration ( Figure 2 ), the footrest platform is configured to support a user in a standing position in the high chair 10. For example, the support surface 18 can be configured to support a user in a standing position in the seated configuration ( Figure 1 ) and standing configuration ( Figure 2 ) and in the seated configuration ( Figure 1 ) the user can sit on the support surface 18, in the standing configuration ( Figure 2 ) the user can stretch across the support surface 18 to stand on the footrest platform 16. In the seated configuration ( Figure 1 ) and standing configuration ( Figure 2), the footrest platform 16 is located on the frame 12 below the seat assembly 14 so that the footrest platform 16 provides a surface to support the user's feet. Figure 1 ) when sitting in the high chair 10, the footrest platform 16 encourages the user to sit in an upright position. In this way, when the user is in the seated configuration ( Figure 1 ) sitting in a high chair 10 or in a standing configuration ( Figure 2 ) When standing in the high chair 10, the foot platform 16 provides a grounding feel for the user, which increases the user's stability in the high chair. The foot platform 16 can extend at least partially on all sides of the frame 12 to provide a wide base for the user to land on. In addition, the foot platform 16 can be completely removed from the frame 12, thereby converting the high chair 10 into a chair with only the seat assembly 14 and no foot platform 16. The support surface 18 and the foot platform 16 are both configured to independently support the full weight of the user, whether the user is in a sitting position in the seated configuration of the high chair 10 or in a standing position in the standing configuration of the high chair 10.

[0098] The support surface 18 may have a peripheral seat frame 22 and a central seat portion 24 within the peripheral seat frame 22. The central seat portion 24 of the support surface 18 is configured to be movable relative to the peripheral seat frame 22 to position the support surface 18 (and thus the high chair 10) between the seating configuration ( Figure 1 ) and standing configuration ( Figure 2 ). In the seated configuration ( Figure 1 ), the central seat portion 24 of the support surface 18 is in a first position flush with the peripheral seat frame 22 to provide a continuous seating surface of the support surface 18 on which a user can sit. Figure 2 ), the central seat portion 24 of the support surface 18 is in a second position exposing an opening 26 defined by the peripheral seat frame 22, through which a user can stretch to stand on the footrest platform 16 below the support surface 18.

[0099] exist Figure 1 and Figure 2 In one embodiment depicted, the central seat portion 24 of the support surface 18 is hingedly secured to the peripheral seat frame 22 and can pivot relative to the peripheral seat frame 22 at hinges 28 to move between the seated configuration ( Figure 1 ) and standing configuration ( Figure 2 ) between. Specifically, the central seat portion 24 can be hingedly secured to the rear of the peripheral seat frame 22 near where the backrest 20 meets the support surface 18. Figure 1 ), the central seat portion 24 can be pivoted downward toward the opening 26 of the peripheral seat frame 22 to form a continuous seating surface of the support surface 18, and in the standing configuration ( Figure 2), the central seat portion 24 is pivoted upwardly away from the opening 26 toward the backrest 20 to expose the opening 26 through which the user can stretch to stand on the footrest platform 16 below the support surface 18. In the standing configuration ( Figure 2 ), when the central seat portion 24 is pivoted upwardly away from the opening 26 and toward the backrest 20, the central seat portion 24 forms an auxiliary standing backrest 30 for supporting the user in a standing configuration ( Figure 2 ) user. The central seat portion 24 may include a cushion 32 or pad located on the underside of the central seat portion 24 so that when the central seat portion 24 is pivoted upward in the standing configuration ( Figure 2 ), the auxiliary standing backrest 30 formed by the central seat portion 24 provides comfortable and cushioned support for the user's back through the seat cushion 32.

[0100] exist Figures 3 to 7 In another embodiment depicted, the central seat portion 24 of the support surface 18 can be fully inserted into and removed from the support surface 18 to be moved between the seated configuration ( Figure 3 ) and standing configuration ( Figure 5 ). For example, in the seated configuration ( Figure 3 ), the central seat portion 24 can be inserted into the support surface 18 to cover the opening 26 and form a continuous seating surface of the support surface 18, while in the standing configuration ( Figure 5 ), the central seat portion 24 can be removed from the support surface 18 to expose the opening 26. In this embodiment, the central seat portion 24 of the support surface 18 can be removably connected to the peripheral seat frame 22 of the support surface 18 at the periphery 34 of the opening 26, for example, using a stepped interface (as shown), a mortise and tenon connection, magnets, posts and grooves, or any other suitable fixing means. In this way, the central seat portion 24 of the support surface 18 can be easily removed from the peripheral seat frame 22 to expose the opening 26 and the support surface 18 and the high chair 10 can be moved from the seating configuration ( Figure 3 ) to a standing configuration ( Figure 5 ).

[0101] In this embodiment, specific reference is made to Figure 7 The backrest insert 36 can be inserted into or removed from the support surface 18 to form an auxiliary standing backrest 30 for supporting a user in a standing configuration ( Figure 5). For example, the backrest insert 36 can be planar, or can be curved along the periphery 34 of the opening 26 of the support surface 18, and can extend vertically from the periphery 34 of the opening 26. The backrest insert 36 can be removably connected to the peripheral seat frame 22 of the support surface 18 at the periphery 34 of the opening 26, for example, using a stepped interface, a mortise and tenon connection, magnets, struts and grooves, or any other suitable fixing means. The backrest insert 36 can also be connected to the support surface 18 in the seated configuration ( Figure 3 ) to provide additional support to the user when the user sits on the support surface 18. The backrest insert 36 may also include a cushion or padded fabric on its front side to provide comfortable and cushioned support for the user's back. Similarly, in the sitting configuration, the seat cushion insert may be inserted into or removed from the support surface 18 to provide additional support and comfort to the user when the user sits on the support surface 18 in the sitting configuration. The seat cushion insert may be provided in a variety of standard sizes according to various growth stages, or may be customized for a specific growth stage of the user.

[0102] In either embodiment, the seat assembly 14 may also include a crotch post 38 secured to the support surface 18 (e.g., on the peripheral seat frame 22) for providing a barrier in front of the user when the user is sitting or standing on the high chair 10. The crotch post 38 may be removable or non-removable from the support surface 18. The crotch post 38 may also provide an anchor point for securing the crotch strap 40 and the restraint strap assembly 44. Specifically, referring to Figure 8-Figure 10 , the seat assembly 14 may include a crotch strap 40, which is fixed to the support surface 18 at a first end of the crotch strap 40 and a second end of the crotch strap 40. Therefore, the crotch strap 40 is configured to extend from the first end across the opening 26 to the second end so that when the user stands in the high chair 10, his legs can be straddled on the crotch strap 40. The seat assembly 14 may include a crotch strap retainer for retaining the crotch strap 40 on the seating surface 18 when not in use (for example, when the high chair 10 is in a seating configuration). The crotch strap 40 can be removably fixed to the peripheral seat frame 22 at least one of its first end or second end. Specifically, one or more ends of the crotch strap 40 can be removably connected to, for example, at least a portion of the periphery 34 of the opening 26, the peripheral seat frame 22 itself, the backrest insert 36 and / or the crotch column 38. For example, at least one end of the crotch strap 40 may include a fixing 41 for removably connecting the crotch strap 40. For example, the fixing 41 can be a buckle. As Fig. 9 and Fig.10 As shown, the fixing member 41 can be integrated into the crotch column 38, or as shown in FIG. Figure 8As shown, the fixing member 41 can be separately fixed to the peripheral seat frame 22. The crotch strap 40 can be removed from the seat assembly 14 as a whole, for example, for cleaning or replacement. The crotch strap 40 can be made of a soft and flexible material (such as fabric) and can have one or more wings 42 extending from its side edges. The wings 42 can be provided, for example, for comfort to the user and to prevent chafing of the user's legs.

For example, an adjustment slot may be provided on the backrest 20, into which each of the two shoulder restraints 50 may be secured to adjust the position of the two shoulder restraints 50 relative to the user in the seat assembly 14. In addition, the high chair 10 may include a belt storage device, such as a slot, a slot, a magnet, or any other suitable storage device, to which the two shoulder restraints 50 may be secured so as to keep the two shoulder restraints 50 out of the way when not in use. It should be understood that the restraint assembly 44 described and depicted herein is provided as a non-limiting example, and various variations and other suitable belt assembly configurations may be applicable to the restraint assembly 44 of the high chair 10. For example, a diagonal restraint may be used in the high chair 10. In addition, the restraint assembly 44 may include one or more pads along any one of the restraints to increase the comfort of the user and / or address the sensory sensitivity of the user.

[0107] like Figure 1-Figure 2 and Figure 7 As shown, the high chair 10 may include a plurality of armrests 56 and at least one removable tray 58, the plurality of armrests 56 are each arranged on a corresponding lateral side of the seat assembly 14, and the at least one removable tray 58 is configured to extend between the plurality of armrests 56 and variably engage the plurality of armrests 56. Specifically, the plurality of armrests 56 may include two armrests 56, each armrest 56 is positioned on one lateral side of the seat assembly 14 and is configured to support at least one removable tray 58 therebetween. In one embodiment, reference Fig.12 , each of the plurality of armrests 56 may include an armrest slot 60 into which the lateral side 62 of the at least one removable tray 58 slides and fits. For example, the armrest slot 60 and the lateral side 62 of the at least one removable tray 58 may have complementary shapes configured to securely support the at least one removable tray 58 in each of the plurality of armrests 56 when the at least one removable tray 58 is engaged with each of the plurality of armrests 56. It should be understood that Fig.12 The complementary shapes shown in are provided as non-limiting examples, and other complementary shapes may be employed. The at least one removable tray 58 may be configured to slide inwardly and outwardly along the slot 60 so that the at least one removable tray 58 may be positioned closer to or further away from the child in the high chair 10 as desired.

For example, Fig.14 and Fig.15 As shown, the integrated tray lock 66 may include a spring loaded release lever 68 which may be engaged in a tray locked position ( Fig.14 ) and tray release position ( Fig.15 ). Fig.16 As shown, the pull rod 70 can be accessed by another user (child's caregiver), for example, on the bottom surface of at least one removable tray 58, toward the front of at least one removable tray 58, while the user (child) cannot reach there. Fig.14), the spring 72 of the integrated tray lock 66 biases the spring-loaded release lever 68 to engage with one of the plurality of adjustment holes 64 of at least one of the plurality of armrests 56, thereby firmly engaging the at least one removable tray 58 with at least one of the plurality of armrests 56. In order to disengage the at least one removable tray 58 from at least one of the plurality of armrests 56, the spring-loaded release lever 68 can be moved to the tray release position ( Fig.15 ). In the tray release position ( Fig.15 ), the force of pulling the pull rod 70 compresses the spring 72 and releases the bias on the spring-loaded release lever 68, causing the spring-loaded release lever 68 to disengage from one of the plurality of adjustment holes 64. Fig.15 ), at least one removable tray 58 can be freely moved toward or away from a user in the high chair 10 based on the number and position of the plurality of adjustment holes 64.

[0109] The spring-loaded release lever 68 may include a chamfered edge 74 where the spring-loaded release lever 68 engages each of the plurality of adjustment holes 64. Thus, when the at least one removable tray 58 is moved toward a user in the high chair 10, each of the plurality of armrests 56 may slide along the chamfered edge 74 and push the spring-loaded release lever 68 toward the tray release position ( Fig.15 ), thereby allowing the at least one removable tray 58 to be moved toward the user in a ratchet mechanism without engaging the pull rod 70. However, the at least one removable tray 58 cannot be moved away from the user without engaging the pull rod 70.

[0110] exist Figure 17-Figure 24 In other embodiments shown, each lateral side 62 of the at least one removable tray 58 may include a tray slot 76 into which at least one of the plurality of armrests 56 slides and fits.

For example, when the lateral side 62 of the at least one removable tray 58 moves toward the integrated latch groove 82 along at least one of the plurality of armrests 56 toward a user in the high chair 10, the latch 84 is configured to be captured by the integrated latch groove 82. In order to disengage the at least one removable tray 58 from at least one of the plurality of armrests 56, the elastic sheet 86 may be lifted to disengage the latch 84 from the integrated latch groove 82. Fig.23 At least one removable tray 58 is shown in an unlocked position, wherein the latch 84 is not secured by the integrated latch recess 82, and Fig.24 The at least one removable tray 58 is shown in a locked position with the latch 84 secured by the integrated latch recess 82 .

[0113] Additionally or alternatively, the at least one removable tray 58 can be connected to the plurality of armrests 56 by an alternative or additional suitable connector, such as a magnet, which is strong enough so that the at least one removable tray 58 cannot be removed by a user when secured to the plurality of armrests 56. It will be appreciated that these connector arrangements are provided as non-limiting examples, and that other suitable arrangements can be used to connect the at least one removable tray 58 to the plurality of armrests 56. In addition, the at least one removable tray 58 can be connected to the plurality of armrests 56 in a manner that allows for vertical adjustment of the at least one removable tray 58 relative to the seating surface 18. It will also be appreciated that the high chair 10 can be used with or without the at least one removable tray 58 connected, such as when being wheeled over a table.

[0114] The at least one removable tray 58 may include two removable trays, each having a different size. For example, the first removable tray may be a larger tray having a first lateral width, and the second removable tray may be a smaller tray having a second lateral width, the second lateral width being less than the first lateral width. Additionally or alternatively, as Figure 25-28 As shown, at least one removable tray 58 may be foldable so that it is configured as a larger tray 58a or a smaller tray 58b. As shown, at least one removable tray 58 may include a tray hinge 88, which is operable to fold the at least one removable tray 58 so that a portion 90 of the at least one removable tray 58 is folded under another portion 92 of the at least one removable tray 58, thereby removing the at least one removable tray 58 from the larger tray 58a ( Fig.25 and Fig.26 ) is converted to a smaller tray 58b ( Fig.28 ). According to any of the above embodiments, both the larger tray 58a and the smaller tray 58b can be connected to the plurality of armrests 56 at their respective lateral sides 62. At least one of the at least one removable tray 58 can include a removable tray cover configured to be easily removed from the at least one removable tray 58 for cleaning. For example, the removable tray cover can be cleaned in a dishwasher.

[0115] The first and second removable trays 58 can be interchangeable in the high chair 10, and the plurality of armrests 56 can be configured to receive and support the first and second removable trays 58. That is, at least one of the plurality of armrests 56 can be movable to variably engage and receive at least one removable tray 58. For example, at least one of the plurality of armrests 56 can be pivotally and / or slidably mounted to the seat assembly 14 so that they can pivot laterally and / or vertically relative to the seat assembly 14, and / or slide laterally. For example, as Fig.29 and Fig.30As shown, at least one of the plurality of armrests 56 may be slidably mounted to the seat assembly 14 such that the plurality of armrests 56 may be moved to accommodate and support at least one removable tray 58 of various sizes (e.g., Fig.29 The larger tray 58a shown and the Fig.30 The smaller tray 58b is shown.

[0116] At least one of the plurality of armrests 56 may be vertically pivotally mounted to the seat assembly 14 such that at least one of the plurality of armrests 56 may be vertically pivotally mounted relative to the seat assembly 14. Figure 31-Figure 33 As shown, at least one of the plurality of armrests 56 can be mounted on a support rod 94 including a recessed track 96, and at least one of the plurality of armrests 56 is configured to slide in the recessed track 96 to accommodate at least one removable tray 58 of various sizes. That is, at least one of the plurality of armrests 56 may include a support rod connection hole 98 for sliding on the support rod 94 and a guide piece 100 extending from the support rod connection hole 98, and the guide piece 100 is configured to engage with the recessed track 96 of the support rod 94. Figure 31-Figure 33 As shown by the directional arrow 102 in FIG. 1 , the concave rail 96 of the support rod 94 may extend laterally (allowing the guide piece 100 to slide laterally relative to the concave rail 96) and / or extend tangentially, such as Figure 31-Figure 33 The directional arrow 104 shown in FIG. 100 (allowing the guide piece 100 to slide tangentially, thereby allowing at least one of the plurality of armrests 56 to vertically pivot relative to the seat assembly 14). The recessed track 96 can extend tangentially at a predetermined position along the support rod 94 to accommodate and support the larger tray 58a and the smaller tray 58b, respectively. Fig.32 At least one of the plurality of armrests 56 is depicted in a downwardly pivoted position to accommodate a larger tray 58a, while Fig.33 At least one of the plurality of armrests 56 is depicted in an upwardly pivoted position such that the at least one of the plurality of armrests 56 may be moved tangentially.

The backrest 20 can be pivotally mounted to the support rod 94 so that the backrest 20 can be tilted relative to the support surface 18. Specifically, the backrest 20 can include a spring-loaded sliding rod 106, and another user (a caretaker of the child) can contact the spring-loaded sliding rod 106 on the back of the backrest 20 and variably move the protrusion 108 of the backrest 20 to engage or disengage one of the plurality of slots in the support rod 96, thereby variably tilting the backrest 20 relative to the support surface 18. That is, the spring-loaded sliding rod 106 can be configured to bias the protrusion 108 to engage one of the plurality of slots in the support rod 94. When the spring-loaded sliding rod 106 is pulled, the protrusion 108 is released from the engagement with one of the plurality of slots and is free to move to another of the plurality of slots. For example, the first slot 110 may be positioned on the support rod 94 such that the backrest 20 can be upright relative to the support surface 18 when the protrusion 108 engages the first slot 110, and the one or more additional slots 112 may be positioned on the support rod 94 such that the backrest 20 can be in one or more inclined positions relative to the support surface 18 when the protrusion 108 engages the one or more additional slots 112. It should be understood that the backrest 20 can be inclined relative to the support surface 18 in another manner.

[0119] The seat assembly 14 (including the plurality of armrests 56) and the foot platform 16 may be independently or commensurately adjustable in the vertical direction along the frame 12 (specifically, along the pillars 13 of the frame 12) to accommodate different heights and positions of the high chair 10. The pillars 13 may have markings (e.g., consecutive numbers or letters) along the vertical direction of the pillars 13 for identifying different positions along the pillars 13. Thus, for example, a user may establish one or more personalized positions for one or both of the seat assembly 14 and the foot platform 16 corresponding to corresponding markings along the pillars 13 based on the size of the user and / or the desired height and position of the high chair 10 (e.g., when the high chair 10 with or without at least one removable tray 58 attached is pushed to the edge of a table, versus when the high chair 10 is freestanding).

[0120] At least one of the seat assembly 14 and the footrest platform 16 may include an integrated mating feature 113 configured to variably secure at least one of the seat assembly 14 and the footrest platform 16 to the pillar 13. For example, the integrated mating feature 113 of the seat assembly 14 may be located on a support rod 96 that supports the seat assembly 14. For example, Fig.36 As shown, the integrated mating feature may take the form of an adjustment support 114 that is permanently connected to and extends from the support rod 96. Fig.38 The pillar 13 may include a plurality of adjustment support hooks 115 positioned along the vertical direction of the pillar 13 , the adjustment support hooks 115 being used to receive the adjustment support member 114 and support the adjustment support member 114 , the support rod 96 and the seat assembly 14 at different heights along the pillar 13 .

The integrated mating feature 113 may be configured to slide over and around the pillar 13 and have at least one corresponding geometric protrusion 122 opposite to at least one side of the pillar 13 having the plurality of geometric recesses 120. In this way, the integrated mating feature 113 is configured to be in a first position ( Fig.44 ) is free to move vertically relative to the support 13, in which position at least one corresponding geometric protrusion 122 is disengaged from at least one of the plurality of geometric recesses 120. When the integrated mating feature 113 is tilted to the second position ( Fig.45), at least one corresponding geometric protrusion 122 is configured to engage with at least one of the plurality of geometric recesses 120. In the second position ( Fig.45 ), gravity, the seat assembly 14, and the downward force of the user on the footrest platform 16 help ensure that at least one corresponding geometric protrusion 122 engages with at least one of the multiple geometric recesses 120.

[0123] exist Figure 46-Figure 48 In another embodiment shown in , the integrated mating feature 113 can include at least one angled rubber wedge 124, which is configured to be opposite to the pillar 13. Specifically, as in the previously described embodiments, the integrated mating feature 113 can be configured to slide over and around the pillar 13 so that each of the at least one angled rubber wedge 124 is opposite to the pillar 13. In this way, when the integrated mating feature 113 is tilted upward relative to the pillar 13 in the first position ( Fig.47 ), so that when the angled surface of at least one angled rubber wedge 124 is parallel to the surface of the pillar 13, the at least one angled rubber wedge 124 is configured to move freely relative to the pillar 13, thereby allowing the integrated mating feature 113 to move freely vertically relative to the pillar 13. However, when the integrated mating feature 113 is tilted downward relative to the pillar 13 in the second position ( Fig.48 ), so that when the angled surface of the at least one angled rubber wedge 124 engages the pillar 13, the integrated mating feature 113 is fixed to the pillar 13. It should be understood that the pillar 13 may include one or more grooves or recesses for receiving the at least one angled rubber wedge 124 when the integrated mating feature 113 is in the second position. In the second position, gravity and the downward force of the user on the seat assembly 14 and the footrest platform 16 help to fix the at least one angled rubber wedge 124 and the integrated mating feature 113 in place relative to the pillar 13.

[0124] It should be understood that the embodiments of the integrated mating features 113 described and depicted above are provided only as non-limiting examples, and other mechanical means of variably securing at least one of the seat assembly 14 and the footrest platform 16 to the pillars may be employed. For example, the pillars 13 may include protrusions extending therefrom on one or more sides of the pillars 13, and the integrated mating features 113 may include corresponding hooks configured to engage with the protrusions on the pillars 13. Furthermore, the integrated mating features 113 may be variably engaged with the pillars 13 by any conventional fastening means, such as bolts or screws.

The compression lock 126 may be configured to provide tactile or audible feedback when switching between the unlocked position and the locked position. For example, referring to Figure 49-Figure 52 , and involving at least one angled rubber wedge 124 Figure 46-Figure 48 13, an exemplary compression lock 126 is shown in conjunction with the embodiment of the integrated mating feature 113 shown in FIG. In this example, the compression lock 126 can be configured to be located at another portion of the integrated mating feature 113 that slides over and around the pillar 13 so that the compression lock 126 is opposite and engaged with the surface of the pillar 13. Specifically, the compression lock 126 may include a rotation knob 128 operably connected to a rubber stopper 130 that engages with the surface of the pillar 13 and can be moved into and out of compression with the surface of the pillar 13. In the unlocked position ( Fig.49 and Fig.51 ), the rotation knob 128 is in a first position, in which the rubber stop 130 does not move to form a compression on the surface of the pillar 13, so that the integrated mating feature 113 can move relative to the pillar 13. Fig.50 and Fig.52 ), the rotation knob 128 is in the second position, in which the rubber stop 130 moves to the surface of the pillar 13 to compress so that the integrated mating feature 113 cannot move relative to the pillar 13. It should be understood that the pillar 13 may include one or more grooves or recesses for receiving the rubber stop 130 when the rotation knob 128 is in the second position. In this way, in addition to gravity and the downward force of the user, the compression lock 126 is also configured to help fix the integrated mating feature 113 in place relative to the pillar 13. Fig.53 As shown, the integrated mating feature 113 and compression lock 126 may have a housing 132 configured to enclose the assembly of the integrated mating feature 113 and compression lock 126 for aesthetic purposes.
