Abstract

An easy adjusting means for crib balustrade is disposed respectively on a pair of opposite upright posts 51, 51' of a crib frame 5 at decent positions, containing an upper and a lower position regulators 1, 2, a guide post 3 located between the regulators 1, 2, and a sliding block 4 rested on a baluster 53 movable along the guide post 3 for adjusting position of the baluster 53, and by retaining a brake mechanism 44 of the sliding block 4 in the upper or lower position regulator 1, 2, the baluster 53 is adjusted in position and height.

Description

BACKGROUND OF THE INVENTION

This invention relates to an easy adjusting means for crib balustrade, particularly to an easy adjusting means disposed at front frame of a crib for'easy adjusting height of the baluster.
A crib is a well-known safety place for protecting a baby against any accident when playing or sleeping, and it requires no more reiteration as regards importance of baby's security here.
However, a decent and considerate design of the crib is still meaningful to the parents, for example, a baluster height adjustable crib is more convenient for lifting a baby from the crib. An average baluster height adjustable crib is usually provided with a recessed rail at both sides with plural insertion openings for the baluster to reside via a simple insertion mechanism for height choice.
Nevertheless, the foregoing mechanism usually needs more components with relatively complicate design that results in a higher production cost and breakdown possibility.

SUMMARY OF THE INVENTION

For eliminating abovesaid defects, this invention is proposed to provide two sets of easy adjusting means disposed correspondingly at front frame of a crib for more convenient adjustment of the baluster and for lower production cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

As shown in Fig. 1, 2, and 2A an exploded structural view, an elevational perspective view, and another elevational perspective view from a different visual angle, this invention is disposed at a proper position each on a upright post 51, 51' in a crib frame 5 (refer to Fig. 5, 51' not shown). This invention comprises an upper and a lower position regulators 1, 2, a guide post 3 disposed between the position regulators 1, 2, and a slidable block 4 coupled with a baluster 53 of the crib frame 5, movable along the guide post 3.
The upper position regulator 1 is located on top of the upright post 51, and a sliding receptacle 12 is provided in a slide bearing face 11 of the upper position regulator 1, characterized in that an insertion groove 13 is formed on a lateral inner wall 121 at front end of the sliding receptacle 12.
The lower position regulator 2 is located at a proper position below the upper position regulator 1, and a slide bearing face 21 thereof is provided with a sliding groove 22, characterized in that an insertion groove 23 is formed on a lateral inner wall 221 at the front end of the sliding groove 22.
Besides, a projecting joint portion 14, 24 is arranged in inner edge of the upper and the lower position regulators respectively for accommodating two ends of the guide post 3.
The slidable block 4 having a protrusive block 42 receptive in the sliding groove 22 and sliding receptacle 12 disposed on a sliding face 41 corresponding to the slide bearing face 11, 21, characterized in that a reception recess 43 is formed at proper position in the sliding block 4. The reception recess 43 contains a brake mechanism 44 that comprises an elastic element 441 and a limited stop piece 442 resisting against the former being inserted in the insertion groove 13, 23.
As shown in Fig. 3, 3A, 4, and 4A a schematic view of pressing action of the limited stop piece, cutaway section along line IIIB-IIIB, adjustment of the sliding block, and cutaway section along line IVB-IVB of this invention, when adjusting height of the baluster 53 of the crib frame 5, a user is to press down the limited stop piece 442 firstly and release it from the insertion groove 23 (13) of the lower (upper) position regulator 2 (1), so that the sliding block 4 can be moved up or down along the guide post 3 to reenter the upper (lower) position regulator 1 (2), and the baluster 53 of the crib frame 5 is adjusted accordingly. When the limited stop piece 442 is reentering another position regulator 1 (2), it is forced by the elastic element 441 to keep retained in the insertion groove 13 (23), and thereby to fix the baluster 53 of the crib frame 5 in place.
As shown in Fig. 5 a schematic view of an embodiment of this invention, one set of support beams 6 is laid between a pair of traverse beams 52, 52' (52' not shown) to permit a bed board 7 lying thereon at a height level about the same of an average bed to facilitate taking care of baby in nighttime.
In addition, plural lower position regulators 2 may be arranged to said upright post 51, 51' at decent positions, such as equally divided intervals for example, to provide more adjustable positions of the baluster 53.
Although, this invention has been described in terms of preferred embodiments, it is apparent that numerous variations and modifications may be made without departing from the true spirit and scope thereof, as set forth in the following claims.
