Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The field of the invention relates to crib dropside assemblies and the hardware used in connection with such assemblies.

2. Brief Description of the Related Art

Cribs are generally provided with dropsides which can be maintained either in raised or lowered positions. The dropside is raised to prevent an infant from climbing out of the crib. It is moved to the lowered position to facilitate access to the infant. A number of dropside assemblies have been developed for positioning the dropside in selected positions. U.S. Pat. No. 5,072,464 discloses one such assembly including a cable and spring-loaded locking pins. Another type of dropside assembly, which is presently in commercial use, includes a generally J-shaped pin track and a pin which is positioned in the pin track. The positioning of the pin in the track determines whether the dropside is in the raised or lowered positions.

Cribs are often provided to consumers in unassembled form. Ease of assembly is accordingly desirable. Some cribs are designed for conversion to day beds upon removal of the dropside. The ability to easily remove the dropside facilitates such conversion. As dropsides are frequently raised and lowered, the ability to do so smoothly is a desirable feature.

SUMMARY OF THE INVENTION

The invention relates to a crib dropside assembly and certain unique components thereof.

In accordance with the invention, an assembly for a crib is provided which includes a crib endboard, a dropside and a dropside track including a generally J-shaped pin track and a pin access slot extending between the pin track and an exterior surface of the dropside track. The dropside track is preferably mounted to the dropside. Means are provided for opening and closing the pin access slot. A pin is preferably secured to the crib endboard, and is slidably positioned within the pin track. The dropside may be coupled to the crib endboard by causing the pin to move through the pin access slot and into the pin track when the pin access slot is opened. The pin access slot is thereafter closed to prevent the dropside from being unintentionally uncoupled from the crib endboard.

A crib dropside assembly is further provided by the invention which includes a top rail, a bottom rail, and a plurality of connecting members extending between the top and bottom rails. A pin track including a relatively long and generally vertical segment, a relatively short and generally vertical segment, a connecting segment connecting the relatively long and short segments, and a pin access slot extending into one of the segments of the pin track. A moveable gate is provided for blocking the pin access slot when in a first position and opening the pin access slot when in a second position.

A pin track assembly is further provided by the invention. The assembly includes an elongate member, a pin track defined by the elongate member and including relatively short and relatively long vertical segments, a connecting segment, a pin access slot extending into one of the segments, and a gate coupled to the elongate member, the gate being movable between a first position blocking the pin access slot and a second position opening the slot. The pin track assembly is mountable to one of the dropside and crib corner post, but preferably to the dropside.

DETAILED DESCRIPTION OF THE INVENTION

The present invention provides a crib dropside that can be installed or removed easily. In addition to facilitating crib assembly for the consumer, it also allows the easy conversion of the crib to a day bed when the dropside is removed. The ability to convert a crib to a day bed is not a requirement of the invention.

FIGS. 1A and 1B each show a crib endboard 10 having a dropside 12 mounted thereto. The dropside includes substantially parallel top and bottom rails 14 , 16 connected by vertical slats 18 and end pieces 19 . The crib endboard shown in the drawings includes a pair of corner posts 20 connected by top and bottom rails 22 , 24 . Vertical slats 26 or the like extend between the top and bottom rails.

FIG. 2A shows the crib endboard having an upper guide 28 and a stabilizing bar bracket 30 secured to one of its corner posts. An enlarged view of the upper guide is shown in FIG. 2 B. As shown in FIG. 2C , a track pin 32 is integral with the stabilizing bar bracket. Such positioning of the track pin is preferred, though not required. While not preferred, the positions of the track pin and pin track (discussed below) could be reversed. A stabilizing bar 34 is coupled to the bracket.

FIGS. 3 A- 3 C show selected portions of the crib dropside. As best shown in FIG. 3B , the upper portion of the dropside includes an end cap 36 and a T-slot 37 for the upper guide 28 . (The upper guide is shown in FIG. 2B. ) The lower portion of the dropside includes an elongate member embedded therein which includes a pin track 40 , a pin gate 42 , and a pressure flipper 44 . The track pin 32 shown in FIG. 2C is located within the pin track when the dropside is mounted to the crib endboard.

FIGS. 4 A- 4 C are exploded, perspective views of the dropside 12 and various elements coupled thereto. FIG. 4B shows the end cap 36 , the recess 37 in the end piece for receiving the end cap, and the screw 39 for securing the end cap to the end piece 19 . As shown in FIG. 4C , a spring 46 is coupled to the pressure flipper 44 . The end rail of the dropside includes an elongate, substantially vertical groove 48 near its bottom end. A pair of openings extend within the groove, and are registrable with the openings near the bottom end of the elongate member. A screw 49 extends through lowermost openings when the elongate member is positioned within the groove 48 .

FIGS. 5 A- 5 G provide detailed views of the elongate member 50 which defines, inter alia, the pin track 40 . The pin track is comprised of relatively short and long generally vertical segments 40 A, 40 B, and a connecting segment 40 C. The upper end of the track 40 is enlarged for receiving a resilient bumper (not shown). The groove 48 in the dropside in which this elongate member is positioned is shown in FIGS. 4A and 4C . While the bottom of the elongate member is secured to the dropside by a screw, the upper end of the groove 48 includes an undercut which receives a lug 52 extending from the upper end of the elongate member. The track assembly for the dropside is shown in FIG. 4C , and includes the elongate member, the pin track, the track assembly screw, the pressure flipper spring, the track pin gate, and the pressure flipper.

FIGS. 6 A- 6 C provide detailed views of the stabilizing bar bracket 30 , which was discussed above in connection with FIG. 2 C. It includes a surface 54 for activating the pressure flipper. This particular bracket includes a plate 56 having mounting holes 58 for a wood stabilizing bar 34 . In the event a metal stabilizing bar is to be employed, different coupling means would be utilized.

FIGS. 7 A- 7 C provide detailed views of the preferred pin gate 42 , which is also shown in FIGS. 3C and 4C . The pin gate is rotatably mounted to the elongate member 50 , as shown in FIG. 3C , to control access to and from the pin track 40 . As shown in FIG. 5A , the track includes a pin access slot 60 . The pin gate can be rotated to block the pin access slot once the track pin is positioned in the pin track. Using the driver slot 62 shown in FIG. 7B , the pin gate can be rotated to align a pin passageway 64 in the pin gate with the pin access slot 60 , thereby permitting the track pin 32 to move in either direction through the pin access slot and into the pin track 40 . As seen in the figures, for example FIG. 4C , the pin can move in the pin track along a generally elongated axis, and the pin can move in the access slot, through the passageway of the pin gate, along a generally elongated axis, the axis of the pin track and the axis of the access slot being generally coplanar. A stop lug 66 is provided to prevent over-rotation of the pin gate and to perform an indexing function. It is engageable with opposing stops 68 formed in the elongate member 50 , which are shown in FIG. 5 B. The lug and stops ensure that the pin passageway is properly aligned to open or close the pin access slot when the pin gate is rotated by the user between selected positions. While the pin gate 42 described herein is adapted to be rotated with the use of a screwdriver, it will be appreciated that other means to provide rotation with or without the use of a separate tool may be employed.

FIGS. 8 A- 8 C include detailed views of a spring hanger 70 , one of which is mounted to each corner post. A first hole 72 is provided near one end for securing the hanger to a corner post. A second hole 74 near the other end is used to couple it to a spring deck (not shown). A laterally extending tab 76 is engageable with the spring deck frame, which limits its rotation.

FIGS. 9 A- 9 C provide detailed views of the upper guide 28 , which is also shown in FIGS. 2A and 2B . The guide includes round corners to minimize friction as it travels in the T-slot 37 shown in FIG. 3 B. It further includes a counterbored passage so that it may be coupled to a corner post 20 with a screw.

The dropside top end cap 36 is shown in detail in FIGS. 10 A- 10 D. As shown in FIG. 10D , it includes a T-slot 78 . This slot is aligned with the T-shaped slot 37 in the dropside, as shown in FIG. 3 B. The end cap includes a guide funnel 80 which allows the user to locate the end cap 36 over the upper guide 28 very easily. This greatly facilitates assembly of the dropside to the crib ends. The cap also fills the gap between the dropside and the crib endboard. The cap surface 82 also functions as a glide that runs up and down on the crib corner post 12 to help eliminate scratching and make it easier to operate.

FIGS. 11 A- 11 C provide detailed views of the pressure flipper 44 . This member is shown as assembled to the dropside in FIGS. 3C and 4C . FIGS. 12 A- 12 B provide detailed views of the pressure flipper spring 46 which is positioned within the spring pocket 82 as labeled in FIG. 11 A. The pressure flipper, under the force of the associated spring, apply pressure to the dropside when it is raised and comes in contact with the stabilizing bar bracket 30 , pushing the dropside out and allowing the pin 32 extending from the stabilizing bar bracket to fall into the locked position of the track. As discussed above, the stabilizing bar bracket has a surface 54 for causing the pressure flipper to become activated when the dropside is raised into the locked position. (The track pin 32 is positioned against the upper wall of the shorter vertical segment 40 A of the pin track 40 when the dropside is in the raised, locked position.)

The embodiment of FIGS. 1 - 12 is assembled in the following manner. The upper guide 28 , stabilizing bar 34 and bracket 30 are assembled to the crib endboard 10 as shown in FIG. 2 A. The dropside 12 is mounted to the crib endboard by placing the dropside end caps 36 over the upper guides 28 on the crib endboards, then swinging the lower dropside over the pins 32 on the stabilizing bar brackets. The track pin gates may be rotated to accommodate the pins, if necessary. As discussed above, the stop lugs 66 ensure that the pin access slots are either fully open or fully closed, thereby providing an indexing function to assist the user. The dropside is raised into the upper position, and the track pin gate is then rotated until the stop lug is again engaged, thereby indicating closure of the pin access slot 60 . When the dropside is raised into the locked position, the pressure flipper rides 44 on the surface of the stabilizing bar bracket, applying pressure to the dropside and forcing it into the locked position. The dropside is easily removed by reversing the above described process.

FIGS. 13A , 13 B and 14 show an alternative embodiment of the dropside track. In this embodiment, the rotatable track pin gate of the first embodiment is replaced by a pivotable gate 100 , as best shown in FIG. 15 . The gate includes an opening 102 at one end which allows it to be pivotably secured to the track, and a hook 104 near the other end for engaging an undercut portion 106 of the track to maintain it in a closed position. The central portion 108 of the gate closes off the pin access slot, as shown in FIG. 13B. A tab 110 allows the gate to be easily maneuvered by user. Other forms of gates could also successfully be employed, such as a slidable member mounted to the elongate member. While some form of attachment of the gate to the elongate member is highly preferred, the use of a separable stop is also a possibility. The stop may be connected to the elongate member by a tether or the like, or not connected at all. Such a stop would be removably insertable in the pin access slot and maintained therein by a suitable detent mechanism.

While the drawings provided herein show only one side of a crib end or dropside, it will be appreciated that the hardware disclosed herein is preferably provided at both sides thereof It will also be appreciated that while preferred embodiments of the invention have been described herein, the scope of the invention is not limited to these particular embodiments.
