Definitions

• the present invention relates to an adapter for a child car seat, facilitating convenient transport of the child car seat outside a vehicle without attaching it to the support frame of a pram.
• a child's car seat is disclosed, transformable into a car seat on wheels, consisting of the front head area, and the back feet area, the head area is higher than the feet area; the right and left front pair, the rear legs and the holder.
• the legs of each pair have their distant end connected with the wheels and another end connected with the seat in the fitting area corresponding to them. Both legs are rotating with respect to each other and with respect to the seat between the folded position, which is applied in the car in the car seat mode, and the operational position applied in the mobile seat mode.
• the legs may also have intermediate position between the folded position and the operational position, and may rotate between the intermediate and the operational position, at least under the effect of gravity.
• Polish patent description Pat.220228 discloses an adapter for the support frame of a children's pram, designed to connect the nacelle of a pram, a stroller, or a child seat to the support frame of a pram.
• the adapter has a boxlike, two-part casing, having on its longer, top side, and on its shorter side an elongated fixing skewed socket. In the basis of the casing, there are two locking-releasing elements installed rotationally, and an elastic ejector.
• the majority of the child car seats offered on the market is equipped with keys placed on both sides of the child car seat. They are used to fasten a child car seat, with appropriate, manufacturer - specific - adapters, to the support frame, transforming the whole into a pram. Also, there are seats with built-in, permanently fixed equipment allowing to move the seat outside a vehicle.
• the purpose of the invention was to develop a solution with universal structure, intended for child car seats of different manufacturers, and facilitating safe and convenient transport of a child sitting in a child car seat with no need to use foldable support frames or the need to carry the child car seat.
• the nature of the invention is an adapter for child car seats characterized in that it consists of two travel elements and of a holder, provided that a travel element has two arms connected to one another at an angle ranging from 60° - 160°, of which the thicker arm is ended by a fixing socket with its shape matching the key of a child car seat, on the second arm, there is a rotating wheel installed, while the holder is in the form of an elongated element to be connected to the handle of a child car seat.
• the fixing socket has on the external side of the adapter's arm a centrally positioned semicircular elongated locating recess, and on the inner side of the adapter's arm, a furrow with the width of the arm, with rounded bottom and side walls, and on one side of the furrow a catch is formed.
• the angle between the travel element's arms is 90°.
• the holder is in the form of a strap with adjustable length.
• the holder is made of plastic.
• the diameter of the wheels of the travel elements is from 8 -18 cm.
• a wheel is fixed to the travel element on a metal rotating axle.
• the term "adapter”, according to the invention, covers the travel elements and the holder, which, after installing in a child car seat, make it possible to transform it into a mobile device for child transport.
• the expression "inner side of the arm of the travel element” is defined as the side which is located closer to a side wall of a child car seat when using the travel element of the adapter, while “the external side of the travel element” is defined as the side where the wheel is installed.
• the shape of the fixing socket of the adapter's travel element makes it possible to use it in car seats of different manufacturers. The location and the size of the catch makes it possible to secure the travel element of the adapter against its uncontrolled disconnection from the key of a child car seat.
• the adapter according to the invention eliminates the need to use foldable support frames and the need to carry the child car seat.
• the minimum diameter of the wheels of the travel elements - 8 cm is necessary to obtain a clearance between the lower part of a child car seat and the ground, which is necessary for the child car seat to travel freely.
• the upper range of the diameter is limited by the stable position of the child car seat during travel, by the protruding elements of the seat, and by its user's safety.
• a holder in the form of an adjustable strap it is possible to guide the child car seat freely, in addition, in the event of obstructions in the form of higher curbs, stairs, holes, etc. by placing the strap on a shoulder and relocating the handle of the child car seat to its carrying position, it is possible to carry the child car seat.
• the use of a holder in the form of an adjustable strap to be placed on a shoulder is more comfortable and applies smaller load than the application of the handle from a child car seat, not adapted for carrying on a shoulder.
• FIG. 5 applying the adapter according to the invention with a rigid holder;
• the embodiment of the adapter according to the invention presented on the figure fig. 1 and fig 2 has a travel element 1 consisting of two arms perpendicular to each other.
• On one, thicker arm there is a fixing socket 2 formed.
• the fixing socket 2 on the external side of the arm is formed in the form of a centrally located semicircular, elongated locating recess 4, while on the inner side of the arm it is in the form of a furrow 5 with the width of the arm, with rounded bottom and side walls, and on one side of the furrow, a catch 6 is formed.
• a rotating wheel 3 is installed on a metal axle 7.
• the holder 8 shown in fig. 3 is equipped with double length adjustment 8a and is made of a textile, adjustable strap.
• FIG. 4 An embodiment of the invention's application is presented in fig. 4, where the adapter according to the invention is shown used in a child car seat.
• the travel elements 1 are attached to the keys of the child car seat placed on its both sides, while the holder 8 is fastened to the handle, being part of the child car seat.
• the application of the adapter according to the invention consists in placing the travel elements 1 in the keys of a child car seat and then in fastening the holder 8 on the seat's handle.
• the fig. 5 discloses an application embodiment of the adapter according to the invention, containing the travel elements 1 and the rigid holder 8.1 folding telescopically, fastened to the handle of a child car seat by means of rounded clamps formed at the end of the holder.
• the travel elements of the adapter according to the invention may be used both with the arm with the wheel facing the front of the child car seat, and with the arm with the wheel facing the rear of the child car seat.
• the catch is a flattened polygon, it is obvious that, according to the invention, it is possible to use a catch of any other shape. Its function is to support its corresponding part located in the key of a child car seat, usually in the form of a hook. As a result, the catch may be rounded or have the shape of another regular figure.
• the holder presented in the embodiment made as a textile strap can also be in the form of a rigid holder made of plastic, wood, metal or another material with the required strength.
• the wheels applied in the invention are standard wheels used in child prams with the diameter from 8-18 cm, equipped with a bearing or without a bearing, with a pneumatic tire or a tubeless tire, made of various materials e.g.: rubber, natural rubber, foam.
• a pneumatic tire or a tubeless tire made of various materials e.g.: rubber, natural rubber, foam.
