The present invention relates to a framework folding mechanism of baby swing, and more particularly, to a framework folding mechanism of baby swing that the user is capable of directly pulling a connecting base-plate to start the folding action of the framework to make the front and rear supporting stands approach each other for folding.
The baby swing is an article for the parents to soothe baby by playing with the baby or regularly swaying to make the baby fall asleep. The function of the baby swing is similar to the baby rocking chair that is classified into two types of product on the market, i.e. the manual one and the electrical one. Take the U.S. Pat. No. 6,319,138 and the Taiwan Patent No. 457,907 for examples, both of the patents use electrical one to drive the baby rocking chair for saving the operator's labor such that his/her nands can do something else. The electrical baby rocking chair mainly includes a supporting frame, two swaying arms, a seat, and a transmitting mechanism. Among them, the transmitting mechanism drives the swaying arms to sway while the swaying arms are connected between the transmitting mechanism and the seat. The seat is driven indirectly to sway back-and-forth by the transmitting mechanism.
Since the above-mentioned baby rocking chairs is bulky and not convenient to store up and the cost of carriage is high, the framework is normally designed to be foldable structure. Take also the U.S. Pat. No. 6,702,685 and the Europe Patent EP1,459,656 for examples, both of their structure disclosed contains foldable framework. However, all the framework folding mechanisms of baby swing of the prior art provide a pressing button for the operator to press to start the action of folding the framework. This kind of press button being exposed on the exterior surface is subject to accidentally touch to generate folding action causing potential hazard, thereby it is inconvenient to operate.
In order to resolve the above-mentioned problems that the framework folding mechanism of baby swing of the prior art is inconvenient in operation that it has the potential hazard of accidentally folding, the invention provides a framework folding mechanism of baby swing that includes a front supporting stand, a rear supporting stand, and connecting base-plate. The connecting base-plate being installed at the top ends of both the front supporting stand and the rear supporting stand has a developed positioning recess and a folded positioning recess for positioning. When it comes to developing the framework, the top end of the rear supporting stand is retained at the developed positioning recess through a resilient element. When it comes to folding the framework, all the operator has to do is directly pulling the connecting base-plate to make the top end of the rear supporting stand separate from the developed positioning recess and subsequently rotate to move to the folded positioning recess letting the rear supporting stand approach toward the front supporting stand for folding. In this way, the folding mechanism of the invention is capable of achieving the effect of safety and conveniency.
The accomplishment of this and other objectives and the range of suitability of the application of the invention will become apparent from the following description and its accompanying drawings of which:
The connecting base-plate (4) being secured at the top end of the front supporting stand (3) is connected to an end of the swaying arm (20) that is driven by a driver (40) provided thereof to rock. The driver (40) further drives the seat (30) to generate back-and-forth sway. Preferably, the connecting base-plate (4) can further includes a developed positioning recess (41) for positioning the developed rear supporting stand (5) and a folded positioning recess (42) for positioning the folded rear supporting stand (5).
The rear supporting stand (5) including a two-sided supporting rod (51) and a supporting bottom rod (52) is substantially appeared “U” shaped structure that is similar to the front supporting stand (3). Besides, the rear supporting stand (5) is pivotally connected to the connecting base-plate (4) through a guided slot (53) provided at the top end of the rear supporting stand (5) itself.
Again, as shown in
To avoid the rocking and swaying of the folded framework (10), it is necessary to have the top end of the rear supporting stand (5) at a positioning state by positioning it at the folded positioning recess (42). Another design alternative is making use of a slant surface to let the rear supporting stand (5) enter and position at its positioning spot (not shown in the Figure) when the framework (10) is in the process of folding. In the present embodiment, the resilient element (50) is a compression spring.
Since the invention has no button-pressing design, when it comes to folding the framework (10), all the operator has to do is directly pulling the connecting base-plate (4) for folding, thus it is capable of avoiding the hazard of touching a button or button by mistake. Therefore, the invention has the advantages over those of the prior art in the effect of safety and conveniency.
It will become apparent to those people skilled in the art that various modifications and variations can be made to the mechanism of the invention without departing from the scope or spirit of the invention. In view of the foregoing description, it is intended that all the modifications and variation fall within the scope of the following appended claims and their equivalents.
