(18) Referring to the figures there is disclosed generally a crib bed 1 having restraining crib bedside wall 2 as of a general type crib bed having spaced vertical bars 3 connected to a crib bed wall support construction 4.

(19) The portion of the crib bed 1 which is utilized for this invention is a detachable restraining crib sidewall 5 with childproof multi action sidewall latching system 6 that is connected to the crib bedside wall 2 and crib bed leg construction 7.

(20) The latching system 6 is attached and integrated into the detachable crib bedside wall 5 at each top corner 8.

(21) The latching system 6 includes a trigger lever 9, trigger lever linkage pin 10, latch housing 11 with novel integrated guide rail 12, latching bar 13, latch bar spring 14, linkage pin 15, latching pin 16, which is spring loaded for automatic latching with the use of a spring 17 and slot 18 horizontal and perpendicular to the latching plane of the latch housing 11.

(22) The latching system 6 insures automatic attachment of the crib sidewall 5 to the crib bed construction 4 without activation of the trigger lever 9 and instead by means of lowering crib sidewall 5 vertically into the stationary guide member 19 within the crib bed leg construction 7. The latching system 6 secures at least one of the crib bedside wall 5 to the constructions to the crib wall support construction 4 utilizing the spring loaded latching pin 16. The latching system 6 requires multiple actions to detach the crib bed side wall 5 from the remaining crib bed construction 4 in a child safe operation.

(23) Attachment of the crib bedside wall 5 occurs when the crib bedside wall 5 is inserted into the leg guide rails 20 with the assistance of centering pins 21 and secondary centered the crib bed assembly 1 with the stationary guide member 19 and the latch housing 11. On lowering the crib bedside wall 5 a spring loaded latching pin 16 is retracted into the latching bar 13 by means of a sloped surface 22. When the crib bed sidewall 5 and latching system 6 reaches the lowest position in the stationary guide member 19, the latching pin 16 is extended horizontally and co-axially to the latching pin 16 utilizing the spring 17.

(24) It is important to child proof and safe operation of the crib bed that the crib bedside wall cannot be detached partially of fully by a child. To insure this the detachable crib bed sidewall 5 utilizes latching system 6 on both sides of the crib bedside wall 5. The latching system 6 is placed at a distance further then the reach of a child or infants arm span. The latching system 6 utilizes a novel ramp in the form of guide rail 12 that guides first a pulling motion of the trigger lever 9 both horizontally and co-axially to the latching pin 16. Through the use of a trigger lever linkage pin 10 connected to the latching bar 13 and assembled linkage pin 15 the latching pin 16 is pulled a partially toward the unlocking position 23. It is novel to the invention of the trigger lever 9 is release at this position or any position the trigger lever 9 and latching pin 16 with connecter assembly will return to the unlocking position 23 utilizing the co-axial latch bar spring 14.

(25) To fully unlock the crib bedside wall 5 a first horizontal and co-axial motion to the latching pin 16 and afterwards a secondary rotary motion of the trigger lever 9 must be applied. The multiple combined actions of horizontal and later rotary motion of the trigger lever 9 is considered childproof and is guided by use of the guide rail 12 within the latching housing 11.

(26) In short, the crib bed 1 is of the general type with at least one detachable crib sidewall 5 that is secured to the crib bed leg construction 7 utilizing a spring loaded latching pin 16 with latching pin including slot 18 perpendicular to the axis of the latching pin 16 where slot 18 is secured to latching bar 13 with a linkage pin 15 through said slot 18 and linkage pin 15 extends through a hole in latching bar 13 where the linkage pin 15 and attached trigger lever 9 is guided by guide rail 12 in latch housing 11 to retract the secured latching pin 16 and latching bar 13 in a motion first which is co-axial and horizontal to the latching pin 16 and afterwards a second motion which is rotational and co-axial to the latching pin 16 and said assembly is spring loaded as to always return to the latch lock position with release of the trigger lever 9.

(27) The crib bed 1 is of the general type with at least one detachable crib sidewall 5 being secured to the crib bed leg construction 7 by means of a latching system 6 including a latch housing 11 on the detachable crib sidewall 5 and a stationary guide member 19 within the crib bed leg construction 7, the latching system 6 being spring loaded as to always return to a latch lock position with release of trigger lever 9, a latching bar 13 being arranged rotatably and displaceably in the latch housing 11 in order to displace a latching pin 16 adapted to engage the stationary guide member 19, the latching bar 13 being provided with the trigger lever 9 at a first end for rotating and displacing the latching bar 13 and the latching pin 16, the latching bar 13 being provided with the latching pin 16 at a second end, and the latching bar 13 being spring-loaded in the latch housing 11 by means of a latch bar spring 14 arranged around the latch bar 13 for engagement of the latching pin 16 with the stationary guide member 19. The crib bed 1 is characterised in that, for attachment of the detachable crib sidewall 5 to the crib bed leg construction 7, the latching pin 16 is retractable into the latching bar 13 against the load of a spring 17 arranged in the latching bar 13 by displacement of the latching pin 16 along a sloped surface 22 of the stationary guide member 19, in that the latching pin 16 includes a slot 18 perpendicular to the axis of the latching pin 16, in that the latching pin 16 is secured to the latching bar 13 with a linkage pin 15 extending through the slot 18 of the latching pin 16 and extending through a hole in the latching bar 13, and in that, for detachment of the detachable crib sidewall 5 from the crib bed leg construction 7, the linkage pin 15 and thereby the attached trigger lever 9 is guided in a guide rail 12 in the latch housing 11 for retraction of the secured latching pin 16 and latching bar 13 in a first motion which is horizontal and co-axial to the latching pin 16 and afterwards in a second motion which is rotational and co-axial to the latching pin 16.
