Definitions
- the present invention relates to furniture for infant, in particular a detachable and positionally adjustable tray and its mounting systems which has an energy-dispersion function and allow an integration with motion sensor and signal transmitter.
- the tray and the mounting system can be installed on chairs, especially on high chairs for infants.
- one of the solution is to add a supplementary tray to the chair at a position lower than the meal table or meal tray, so that dropping foods and tableware could be intercept by the supplementary tray (it is much easier to pick up foods or tableware from a tray close to the meal table than picking up those dropped items from floor).
- US5649737A disclosed a portable chair tray with L- shape supporting frame, can be fixed temporarily by clamp or permanently by screw to the arm-rest of a chair. But such tray can only be installed to a certain type of chair.
- US4662676A disclosed a tray to be fixed on the arm of the chair/wheel, and US5709155A disclosed a tray table capable of folding conveniently against the side of a chair. But in these two inventions, the tray need to be fixed with screws and can not be adjust easily.
- US7900566B1 disclosed an adjustable chair tray with folding function.
- the position, of the tray, and the inclination of the tray can be adjusted.
- the supporting structure is quite complex and the tray is fixed by screw to the supporting structure, so can not be detached easily for daily cleaning.
- the folding mechanism of the system leads to a risk of finger-clamping during the adjustment.
- This invention disclosed an easy-detach and positionally adjustable tray and its mounting system, to be used for example as side-tray of high chair, installed at a position lower than the meal table/tray, to intercept foods and tableware dropped down.
- the position of the tray and inclination level of the tray can be easily adjusted by mounting system, so as to fit for situation with space constraint or according to infant’s habit.
- Motion sensor kit is integrated to the tray and mounting system so that the movement of the tray, mainly due to the dropping of item, is monitored and such information can be used and collected for further exploitation.
- the mounting set includes at least a clamp, a supporting stick, and as complementary device an height adjusting rod, and as complementary device an container frame to accommodate the motion sensors kit.
- the clamp is composed by a rigid frame, a adjusting screws of clamp, a receiver for supporting stick and a adjusting screw for supporting stick.
- the clamp can further comprise a receiver and a adjusting screw for the height adjusting rod.
- the supporting stick can have different cross section at different part along the length.
- One end of the supporting stick is fixed on the clamp (at the receiver for supporting stick, and by the adjusting screw for supporting stick) and the rotative position of the supporting stick with regard to the clamp could be adjusted.
- the other end of the supporting stick is inserted in to the connector of the tray.
- the height-adjusting rod comprise a straight part and a curved part.
- the straight part is fixed on the clamp (at the receiver for height-adjusting rod, and by the adjusting screw for height-adjusting rod).
- the curved part will provide support to the tray.
- the clamp, supporting stick and height-adjusting rod are made of rigid materials.
- the tray has at least one connector, preferable with a hollow section like a socket, at a position close to or at the edge of the tray.
- the tray is installed to the mounting system in a way that the supporting stick is inserted into the connector, which allow an easy installing and detaching.
- the inclination level (in regard to horizontal plane) of the tray can be adjusted between -20° and 90°, by adjusting the rotative position of the supporting stick within the receiver for supporting stick on the clamp.
- the tray can be further stabilized by the adjusting rod, by holding the tray at a position in the flat area of the tray.
- the inclination level of the tray is changing accordingly (rotating around the supporting stick)
- the flat part of the tray is surrounded by a continuous edge wall.
- the periphery of the tray is rounded without any hard corner.
- the upper-side and down-side the tray is mirror-symmetric in regard to the main plane of the tray.
- the tray is made of light material such as plastic.
- Motion - active signal transmitter - A motion sensor is installed on the mounting system, to detect the motion of the tray or/and the motion of the adjusting rod.
- the motion sensor could be any kind of sensor fit for the said application.
- a Piezoelectric sensor is installed on the surface of the adjusting rod at the position with direct contact with the tray.
- An wired or wireless signal transmitter is connected to the motion sensor. Once a motion of the tray or/and the adjusting rod is detected, electrical signal is sent out to at least one third party device. As an example, a signal is sent by the transmitter to an mobile phone via Bluetooth,
- the single-point fixation mounting system can be installed on chairs with single leg or double legs at one side.
- the mounting system (so that the position of the tray) can be fixed to different position of a chair wherever the clamp can be installed. It allows therefore to install the system at a position which can not be reached by the infant.
- the inclination level of the tray (the angle between the tray and the horizontal plan) is adjustable by hand, by changing the position (rotating) of the adjusting rod.
- the tray When the tray is at an up-warded inclined position (comparing to the situation where the tray is in horizontal position), the tray has a higher chance to hold and keep the items dropped down to the tray, without bouncing out of the tray due to the resilience or the deformation of the tray.
- the mounting position in regard to the chair or/and the inclination level of the tray can be adjusted, so as to fit for various limitation of space or to intercept items dropped from different direction according to sensitivity of the infant.
- the tray can be easily installed and detached by hand from the mounting system for daily cleaning.
- the tray can be used either in left-side position or right-side position with symmetrical appearance.
- the tray and mounting system could be connected to a third party device via wired or wireless communication technology. When food or table ware fall on the tray and cause a detectable motion, a signal is sent to a third party electronical device to get a certain response or for any kind of further exploitation.
- Fig.1a illustrates a typical setup of the tray (2) mounted to a chair (1) (not shown) with rectangular-shape side leg (11) at a horizontal position.
