Abstract

A double action securing device for the drop side of a crib comprises a guide member connected to the crib or to the drop side in a vertically oriented position. A slide member is slidably mounted to the guide member between two positions for raising and lowering the drop side. A catch pin is axially mounted to the slide member and engageable with an opening of the guide member in at least one of the relative positions. The catch pin has a head which defines a recess for embracing a lower edge of the guide member opening. The weight of the slide member causes the head recess to drop over the lower edge of the opening to lock the slide member with respect to the guide member. A mattress support is used with the securing device. It has a frame defining a space comprising four vertical brackets connected to four posts of the crib frame. Each bracket has a plurality of vertically spaced open ended slots with open mouths of each slot facing toward a centerline of the crib. A pair of beams which each have pins extending from their end are engaged with the vertical brackets so that at least one pin at one end of each beam is engaged in one slot of each bracket. A cross member engages the beams to hold them apart and hold their pins in the appropriate slot.

Dependent claims

A double action securing device in combination with a crib including a crib frame and at least one drop side vertically movable with respect to the frame, comprising:

an elongated upper guide member connected to the crib frame on each side of the drop side, each upper guide member having at least one opening therein with a lower edge, and each upper guide member having a lower end;
an elongated lower guide member connected to the crib frame on each side of the drop side, each lower guide member being beneath and being aligned with one of said upper guide members, each lower guide member having a lower shoulder near a lower end thereof;
an upper slide member slideably engaged with each of said upper guide members, each upper slide member being connected to one side of the drop side;
a catch pin mounted for axial movement to each upper slide member, each catch pin having a head for engaging into said opening of said upper guide member on which said upper slide member is slideably mounted, each head having a recess for engaging onto said lower edge of said opening for precluding axial movement of said catch pin out of said opening;
biasing means connected to each catch pin for biasing each catch pin in a direction into said opening of its respective upper guide member;
and
a lower slide member slideably engaged with each of said lower guide members, each lower slide member having a shoulder which is engagable with said lower shoulder of its respective lower guide member for precluding any further lowering of said lower slide member on its respective lower guide member, each lower slide member being pivotally connected to one side of said drop side below a respective upper slide member for permitting tilting of the drop side with respect to said upper and lower guide members;
the distance between said lower shoulder of each lower guide member and said lower end of each respective upper guide member being selected so that with said lower slide member shoulder engaged with its respective lower guide member shoulder, said upper slide members are positioned below said lower end of their respective upper guide members, the drop side being thereafter raisable to slide and said upper slide members onto their respective upper guide members.

5 more elements

A mattress support and drop side lock for a crib having a frame with inner surfaces which define a space, said frame having one end and an opposite end and one side and an opposite sides, and a drop side vertically slidable on said frame between its ends the mattress support comprising:

a first pair of spaced apart vertical posts at the one end of the frame, each having an inner surface facing the opposite end of the frame;
a second pair of spaced apart vertical posts at the opposite end of the frame, each having an inner surface facing the one end of the frame;
a vertical bracket connected to each of said vertical posts, each vertical bracket being connected on said inner surface of its vertical post, each vertical bracket having a plurality of vertically spaced slots, each slot having an open mouth and a blind base positioned vertically below the open mouth, the open mouths of slots of each bracket at the one end of the frame facing each other and the open mouths of slots of each bracket at the opposite end of the frame facing each other, the blind bases of slots at each end of the frame being spaced from each other by a greater amount than the open mouths of slots at each end of the frame;
a pair of mattress support beams extending between said first and second pair of vertical posts, one of said mattress support beams being positioned on the one side of the frame and the other of said mattress support beams being positioned on the opposite side of the frame, each mattress support beam having a pair of fixed pins extending from each end thereof, each pair of fixed pins being insertable into a pair of said open mouths and being seated in a pair of said blind bases of a different vertical bracket, pins at one end of each beam being seated in blind bases of vertical brackets of said first pair of vertical posts and pins at an opposite end of each beam being seated in blind bases of vertical brackets of said second pair of vertical posts;
a cross member engaged between and on said pair of mattress support beams for holding each pin seated in its blind base, said cross member acting as stop means for holding said mattress support beams apart, said cross member extending substantially the full length of said mattress support beams from the one end of the frame to the opposite end of the frame and substantially spanning the distance between said support beams from one side of the frame to the opposite side of the frame;
the drop side lock comprising:
a pair of upper guide members connected to opposite ends of the frame, said guide members facing each other;
a slide member slideably mounted for vertical movement on each guide member, said slide members being connected to opposite ends of the drop side, said slide members all being pivotally mounted to the drop side for permitting tilting of the drop side with respect to the frame;
a catch pin axially mounted to each slide member, said catch pin having a head defining a recess for engaging said lower edge of each opening of said guide members when said head is in said opening of one said guide members, said head being of a size to pass into said guide member opening and said opening positioned on said guide member to receive said head in a selected relative position between said slide member and said guide member, said recess receiving said opening lower edge to lock said slide member to said guide member and so that said slide member can be unlocked from said guide member by first raising said slide member to withdraw said opening lower edge from said head recess and then axially withdrawing said head from said guide member opening;
and
biasing means engaged with said catch pins for urging said heads in a direction into said guide member openings.
