Description

Play yard underframe folding structure

[technical field]

The utility model relates to a kind of play yard underframe folding structure.

[background technology]

Baby's game bed (Playyard) wants enough spacious just can not allow infant inside feel compressing.But spacious bed body takes up space very much, and therefore up-to-the-minute design mostly is inclined to based on collapsible baby's game bed (Foldable Playyard).

Collapsible is baby's game bed, and its basic comprising comprises: the wall and the bed end.Utilize the joint when folding, make the handrail of wall can therefrom bend and draw close with the pillar of bed body, this technology has partly developed quite ripely, for example United States Patent (USP) the 4th, 811, and 437 and 5, the disclosed technology contents of patent such as 697,111 are enough to understand wherein secret; In addition, for making its whole skeleton be able to folding, underframe at this skeleton partly is provided with the foldable type skeleton, the folding of controlling whole skeleton by the clip and the release of this underframe, wherein as the U.S.'s the 2003/0061657th A1 patent disclosure case, it mainly is to comprise a base, in order to articulate lower support bar, and be the expansion positioner by the relative restriction lower support bar of a pair of clamping piece, after this connects a rope respectively in addition to clamping piece, spur this simultaneously by a drawstring again clamping piece is moved, and then releasing reaches collapsible state to the restriction of this lower support bar with this.

Disclosed as described above structure, because this is to utilize a drawstring to connect a rope to the moving of clamping piece, spur this respectively to clamping piece by this rope again, make it to remove clip to lower support bar, yet this structure must utilize a drawstring to spur a pair of clamping piece simultaneously, unless being vertical line, this drawstring makes progress, otherwise, when the operator departs from the pulling of drawstring angle, may cause only monolateral clamping piece to move and remove lower support bar, and lower support bar is discharged fully, to reach the purpose of folding skeleton, so it has the shortcoming that its folding was lost efficacy.

In addition, the drawstring of structure noted earlier is that wall scroll passes weaving bottom layer, and only its pipe is that double-deck folding is knitted, but because weaving bottom layer is soft class, through hole is easy to generate variation, thus its drawstring be pulled easily weaving bottom layer below, can not find drawstring, suitable inconvenience when allowing the pulling of operator's desire.

[utility model content]

Main purpose of the present utility model is to be subjected to operating influence bigger during at existing play yard underframe folding, can not be well the deficiency of folding fully, provide a kind of simple, convenient, can play the play yard underframe folding structure of folding effect better.

In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:

A kind of play yard underframe folding structure, main device is characterized in that comprising in the collapsible skeleton bottom of play yard:

One rotation seat, it installs in this pedestal, and its rising wood is provided with a pair of limited part, and this limited part can rotate with this rotation seat and select this support bar is a restriction state or a disarm state, and a helicla flute relative with this pedestal is set on this rotation seat;

One drive rod runs through in the helicla flute of the long slot bore of this pedestal and this rotation seat, and this drive rod can be rotated in this spiral fluted scope in order to drive this rotation seat by upwards pulling of a pull handle, makes the limited part of this rotation seat remove motion limits to this support bar;

One elastic parts, device is between this drive rod and this pedestal, in order to keep the restriction state of this rotation seat to this support bar; And

One weaves cotton cloth, and device is on collapsible skeleton, and wherein at this weaving bottom layer one opening being set at least can run through for this pull handle.

Aforesaid play yard underframe folding structure is characterized in that this elastic parts is an extension spring.

Aforesaid play yard underframe folding structure is characterized in that this pull handle is a ribbon.

Aforesaid play yard underframe folding structure is characterized in that this weaving bottom layer can be provided with pair of openings, for this pull handle pass through around.

Aforesaid play yard underframe folding structure, it is characterized in that this pedestal is provided with a locating hole, the located lateral groove is set on this rotation seat in addition, runs through this locating hole and groove respectively to locating slot, rotate so that this rotation seat gets at grade with a fixed bar.

Aforesaid play yard underframe folding structure is characterized in that this limited part and this rotation seat are integrated.

Compared with prior art, the beneficial effects of the utility model are: 1. owing to be with single pull handle direct pull one drive rod, this drive rod is moved in the helicla flute of rotation seat, and then drive this rotation seat, make the same moved further of the limited part that is located on this rotation seat, make it reach the effect that discharges support bar simultaneously and reach the skeleton folding, it is simple, convenient, and the folding effect is preferable; 2. pull handle of the present utility model is two through holes that can walk around weaving bottom layer, makes this pull handle be subjected to the restriction of weaving bottom layer and can not drop to the below of weaving bottom layer, so can not find the situation of pull handle can not occur using the time.
