DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a collapsible stand suitable for supporting a carry-cot or Moses basket.
A typical prior art carry-cot stand is described in GB-A-2214421. This stand includes a pair of scissor action side frames each of which is provided with a two-part arm, the ends of which are pivotally connected to a different limb of one of the scissor action side frames. As the frame is opened, the two arms are reconfigured from a doubled up configuration to an extended configuration in which arm parts are substantially aligned. Place a carry-cot into an upper region of the stand urges upper portions of each side frame apart thus placing the arms in tension. Once the arms have reached a straight configuration, tension in the arms resists further opening of the side frames. One disadvantage is that this arrangement does not permit the carry-cot supported by the stand to be rocked.
Cots which permit rocking exist but they are not easily foldable into a substantially flat configuration so as to facilitate transportation and storage. Such cots are described in U.S. Pat. Nos. 2,482,318 and 1,336,302.
The object of the invention is to provide a stand suitable for supporting a carry-cot which both allows the carry-cot to be swung and allows the stand to be easily folded flat when not in use.
A further object of the invention is to provide a carry-cot stand which does not require disengagement of any of its parts prior to being folded flat.
Thus according to the invention there is provided a collapsible nursery stand comprising a pair of interconnected scissor action side frames each comprising a pair of limbs and securing means which in a first state secures the stand in an erected configuration and in a second state permits the stand to be collapsed, characterised in that the stand further comprises link means which depend from upper regions of the limbs when the stand is erected for swingingly supporting infant accommodating means.
By providing links which can swing with respect to the limbs constituting the side frames, for supporting infant accommodating means, such links can easily be oriented towards alignment with the limbs when the stand is collapsed. Accordingly, such a stand can easily, without disengagement of any parts from the stand, be reconfigured between an erected and a collapsed state.
In order to provide an easy swinging action the link means preferably depend substantially vertically when the stand is erected and standing on level ground.
The link means preferably rotate through an angle of at least 45.degree. and more preferably through an angle of at least 60.degree. as the stand is collapsed to a configuration in which side frame limbs lie substantially on closely adjacent approximately parallel planes.
So that depending portions of the link means connected to different limbs of each side frame can be interconnected (for example by a frame or platform) while permitting collapsing of the frame without disassembly being necessary, preferably upper regions of the limbs of each side frame move away from each other as the stand collapses.
So as to reduce the number of parts comprised in the stand and so as to increase its rigidity the pair of scissor action side frames are preferably interconnected by two substantially U-shaped link members. For the same reasons the scissor action side frame preferably comprise a pair of substantially U-shaped frame members with pivotally interconnected limbs.
When the link means comprises a pair of U-shaped link members the stand preferably includes spacer means for supporting the infant accommodating means clear of a base portion of each link member in order to reduce frictional forces tending to damp any swinging action of the link means.
Preferably the stand includes a structure interconnecting the link means associated with the upper regions of the limbs of each side frame. Such a structure will increase the rigidity of the stand, facilitate automatic rotation of the link means as the stand is collapsed and can also be conveniently provided in the for
