In one illustrative embodiment, the stop support 66 can be triangularly shaped. The first support portion 90 can be movably coupled to the housing 60 at a ninth joint 96 and can be configured to move between a first support position and a second support position. In one illustrative embodiment, the stop support 66 engages the stop support engaging surface 86 of the stop member 62 when the stop support 66 is in the second support position.
The second support portion 92 can be spaced apart a distance D2 from the first support portion 90 and can be configured to engage the stop support engaging surface 86 as shown in FIGS. 6-10. It should be appreciated that the distance D2 can be the distance between the ninth joint 96 and the stop support engaging surface 86 when the stop member 64 is in the second stop position. In one illustrative embodiment, the second support portion 92 can engage the stop support engaging surface 86 when the stop member 64 is in the second stop position and the stop support 66 is in the second support position.
The third support portion 94 can be spaced apart a distance D3 from the first support portion 90 and can be coupled to the handle engaging portion 88 of the stop member 64 by a spring 98. The spring 98 can expand from a first distance K1 when the stop support 66 is the first support position and the handle 62 is in the first handle position to a second distance K2 when the stop support 66 is in the first support position and the handle 62 is in the second handle position. The expansion of the spring 98 from the first distance K1 to the second distance K2 can cause the stop support 66 to rotate about the ninth joint 96 toward/away from the second support position and/or can cause the handle 62 to move from the second handle position to the first handle position.
To move the siderail 20 from the deployed position to the storage position, the handle 62 can be moved from the first handle position to the second handle position, which can cause the stop member 64 to move from the first stop position to the second stop position and can cause the spring 98 to expand from the first distance K1 to the second distance K2. Moving the stop member 64 to the second stop position can allow the guide member 40 to move along the guide 74. The expansion of the spring 98 can cause the stop support 66 to rotate about the ninth joint 96 so that the first support portion 90 is positioned proximate the stop support engaging surface 86 of the stop member 64 and maintains the stop member 64 in the second stop position.
With the stop member 64 in the second position, the guide member 40 can be free to move along the guide 74. As the siderail 20 moves from the deployed position to the storage position, the guide member 40 can move toward the upper frame 16 along the guide 74. When the guide member 40 reaches the second guide position, the siderail assembly 20 can be in the storage position and the guide member 40 can contact an end of the guide 74. It should be appreciated that the guide member 40 can contact the end of the guide 74 to prevent further rotation.
To move the siderail 20 from the storage position to the deployed position, the siderail 20 can be rotated clockwise with respect to the frame 16. As the siderail 20 moves from the storage position to the deployed position, the guide member 40 can move along the guide 74 from the second guide position toward the first guide position. As the guide member 40 moves toward the first guide position, the guide member 40 can engage a portion of the stop support 66 and urge the stop support 66 to move about the ninth joint 96 from the second guide position to the first guide position. The movement of the stop support 66 about the ninth joint 96 from the second guide position to the first guide position can cause the first support portion 90 to disengage from the stop support engaging surface 86 of the stop member 64 and can cause the spring 98 to expand from the first distance K1 to the second distance K2. The expansion of the spring 98 can cause the stop member 64 to move from the second stop position to the first stop position, which can move the handle 62 from the second handle position to the first handle position. When the stop member 64 reaches the first stop position, the stop member 64 can engage the guide member 40 and prevent the guide member 40 from moving along the guide 74 to maintain the siderail 20 in the deployed position.
Many other embodiments of the present disclosure are also envisioned. For example, a siderail assembly comprises a siderail body, a siderail linkage, and a locking mechanism. The siderail linkage is configured to movably couple the siderail body to a frame of a person-support apparatus. The siderail linkage is configured to move the siderail body between a first position and a second position with respect to the frame. The siderail linkage includes a guide member. The locking mechanism includes a housing with a slot that defines a guide. The guide member is configured to move along the guide between a first guide position and a second guide position as the siderail body moves between the first position and the second position. The locking mechanism is configured to selectively prevent the guide member from moving along the guide to maintain the siderail body in at least one of the first position and the second position.
In another example, a siderail locking mechanism comprises a housing, a guide member, a stop member, and a stop support. The housing includes a slot defining a guide with a first end and a second end. The guide member is coupled to a siderail linkage assembly and is configured to move along the guide between a first guide position and a second guide position.

24. The siderail assembly of claim 23, wherein the guide member is configured to rotate with respect to the slide.

25. The siderail assembly of claim 23, wherein the slide includes a substantially flat portion configured to engage the housing of the locking mechanism to prevent the slide from rotating with respect to the locking mechanism.

26. A method of moving a siderail between a first position to a second position, comprising:

moving a handle from a first handle position to a second handle position to actuate a locking mechanism;

moving a stop member from a first stop position to a second stop position and a stop support from a first support position to a second support position as the handle moves from a first handle position to a second handle position, the stop support being configured to maintain the stop member in the second position when the stop support is in the second position; and

moving a guide member along a guide between a first guide position and a second guide position as the siderail moves between the first position to the second position, the stop member being configured to maintain the guide member in the first guide position when the stop member is in the first stop position.

27. The method of claim 26 further comprising the step of pushing the stop support from the second position to the first position with the guide member as the guide member moves toward the first position, the stop support disengaging the stop member as the stop support moves from the second position to the first position, the stop member moving from the second position to the first position to prevent the guide member from moving along the guide.

28. The method of claim 26, wherein an elastic member is coupled to the handle and stop support, the elastic member causing the stop support to rotate about a first axis from a first support position to a second support position as the handle translates from the first handle position to the second handle position, the elastic member causing the handle to translate from the second handle position to the first handle position as the stop support rotates about the first axis from the second support position to the first support position.
