Description

BUBBLE TOY

  The present invention relates to a toy for making bubbles constructed in the form of an animal such as a hippopotamus and which is designed to produce bubbles when it is pushed by hand onto

floor.

  Bubble-making toys are known in which a soapy solution and a bubble-producing ring are used, the soapy solution being contained in a container With this type of bubble-making toy, a cap of the container is opened and the bubble producing ring is taken out from inside the container Bubbles are produced by blowing on a film of the soapy solution formed on the ring Also known as a spray type bubble toy, in which a container soap solution has a cylindrical body having an air inlet formed in one end and an air outlet formed in the other end With this toy, the soap solution is sucked out of the soap solution container by capillary action in order to form a film of soapy solution at the air outlet, and bubbles are continuously produced by the air outlet by blowing into the air inlet An aut re known bubble-making toy comprises a container in the form of a tray intended to hold a soapy solution and a large ring with a handle This toy is designed to produce large bubbles by immersing the large ring in the soapy solution and then pulling the ring

  up out of the soapy solution.

  The various bubble-making toys described above are of simple construction and have relatively little interest outside of bubble production. They require operations such as blowing and pulling the ring up quickly, which is unsuitable. for young children Consequently, these toys for known bubbles lack originality and also do not bring any surprise to larger children while not being

  easy to use for younger children.

  It is therefore a goal of this

  invention than solving the problems mentioned above

  on it and get a bubble toy that is very easy to handle and surprises

pleasantly children.

  In order to achieve the object described above, the present invention provides a bubble push toy with wheels on the underside and having a toy body, bubble producing means mounted in the toy body and driven by the rotation of the wheels, and an opening section intended to evacuate outside the toy body the bubbles produced by the means of

bubble production.

  The toy body is preferably in the form of an animal with the wheels which are in positions corresponding to the legs of the animal, and the opening section which is in a position corresponding to the mouth of the animal. animal Furthermore, a cam mechanism mechanically connected to the wheels is provided to open and close the part corresponding to

  the animal's mouth when the wheels turn.

  When the toy body is moved by pushing it, the wheels rotate in order to drive the bubble producing means and create bubbles, which are evacuated towards the outside by the opening section of the

toy body.

  The creation and evacuation of bubbles simply by moving the toy body not only makes the toy interesting for the user but also prevents hands from getting dirty. Furthermore, by having the toy body in the form of an animal and designed to blow bubbles through the mouth of the animal while the animal is moving,

very original operation.

  A toy for making bubbles using the invention will now be described by way of example with reference to the drawings, in which identical references refer to identical parts and in which: FIG. 1 is a view in perspective representing the external appearance of a toy for making bubbles according to the invention; Figure 2 is a bottom exploded perspective view of an outer shell of the upper half of the toy for making bubbles according to the invention; Figure 3 is a top exploded perspective view of the outer shell of the upper half of the toy for making bubbles according to the invention; Figure 4 is an exploded perspective view of the toy for making bubbles according to the invention; Figure 5 is an exploded horizontal perspective view of a bubble producing device constituting part of the invention; and Figure 6 is an exploded perspective view of the bubble producing device according to the invention. A toy for making bubbles implementing the invention will be explained below with reference to the drawings. As shown in FIG. 1, the toy for making bubbles is constructed in the form of an animal, a hippopotamus. in the present case The toy for making bubbles comprises a body 1 having a trunk and a head of a hippopotamus The body 1 is made so as to be a caricature of a hippopotamus, and has a large head and short legs and consists of a front outer shell 2 which constitutes the upper jaw and the face of the hippopotamus, a rear outer shell 3 which constitutes the upper half of the trunk, and a lower external shell 4 which constitutes the lower half of the trunk comprising the lower jaw and the legs The front outer shell 2 is normally arranged obliquely upwards with respect to the front of the lower outer shell 4, the mouth tight t half open When the toy body is pushed, the hippo's mouth moves vertically between a half open position and a wide open position in order to cause bubbles S to come out of the mouth as if

  the hippo was blowing bubbles while walking.

  As shown in Figures 2 to 4, the front outer shell 2 is fixed to the rear outer shell 3, which in turn is fixed to the lower outer shell 4 The front end section of the rear outer shell 3 is partially inserted in the rear end section of the front outer shell 2 so as to be connected to it by a joint 5 which constitutes a part

  of a cam mechanism 25 which will be described later.

  The articulation 5 is an intermediate element rotatably mounted inside the front end section of the rear outer shell 3 and on which

  the front outer shell 2 is blocked by screws.

  The joint further has a rear end section which extends into a bubble producing device 6. When the bubble producing device 6 is driven, the front outer shell 2 is rotated in a vertical direction due to the fact of its interconnection with the bubble producing device and the hippo's mouth is repeatedly moved between a half position

  open and a wide open position.

  Furthermore, as shown in FIG. 4, teeth and a tongue element 7 are housed in the front section of the lower outer shell 4 corresponding to the lower jaw of the hippopotamus. The tongue element 7 is provided with a section of solution tank 8 formed in the

  inner part corresponding to the base of the tongue.

  In this solution tank section 8, a liquid L such as a soap solution for bubbles S can be stored Similarly, as shown in FIG. 1, the front end of the bubble producing device 6 is positioned in the tank section 8 in order to make bubbles which are blown forward out of the mouth of the hippopotamus The front outer shell 2 and the front part of the lower outer shell 4 form the mouth of the hippopotamus and constitute the opening section of the body 1 through which the bubbles are discharged S. The device for producing bubbles 6 is housed in a space formed by the rear outer shell 3 and the rear part of the lower outer shell The device for producing bubbles is of unitary construction and comprises a front wheel 9 and two rear wheels 10 The front wheel 9 and the rear wheels 10 extend through lower openings 4 a provided in the lower outer shell 4 When the body 1 is moved over a surface, the bubble producing device 6 is driven by the wheels 9 and 10 in order to open and close the mouth of the hippo Bubbles S are

  blown out of the mouth at the same time.

  The bubble producing device 6 will be explained in detail with reference to FIGS. 5 and 6 As shown in these drawings, the bubble producing device 6 has a pair of frames 21 a and 21 b of separate construction A l inside and outside of these frames 21 a and 21 b are mounted the front wheel 9, the rear wheels 10, a drive gear train 22 and various other parts The bubble producing device 6 is designed to be driven by the force transmitted by the rear wheels 10 when the toy body 1 is moved The bubble producing device includes a film forming mechanism 23 for forming a film of soapy solution, a fan mechanism 24 for blowing air from the inside to the film of soapy solution to produce bubbles S, a cam mechanism 25 for moving the mouth of the hippopotamus, and a gear train of ent ration 22 intended to transmit the

  force of the rear wheels 10 to each of these elements.

  The drive gear train 22 consists, starting from the rear wheel side 10, of an input pinion 31, a first intermediate pinion 32, a second intermediate pinion 33 (which is not illustrated in FIG. 6), a third intermediate pinion 34 and an output pinion 35, which are engaged in the order cited. The input pinion 31 is installed in a fixed manner on an axis 36 on which are mounted rear wheels 10 The axle 36 is rotatably supported by the chassis 2a and 21b The intermediate gears 32, 33, 34 are fixedly mounted on the rotary shafts 37 which are rotatably supported on the chassis 21 a and 21 b The output pinion 35 is freely rotatably mounted on a main shaft 66 of the fan mechanism 24 described later The main shaft 66 extends through the frame 21 a and is rotatably supported by the chassis 21 a and 21 b Sprockets 38 are fixedly mounted on the intermediate pinions 32, 33 and 34 The intermediate pinions 32, 33 and 34 are engaged with the pinions 38 and gradually increase the speed, thus transmitting the force to the film-forming mechanism 23, at

  fan mechanism 24 and the cam mechanism 25.

  The cam mechanism 25 receives the force via the input pinion 31 This force is then diverted to the film forming mechanism 23 from the first intermediate pinion 32, and to the fan mechanism 24 from the pinion of

exit 35.

  The cam mechanism 25 comprises a rotary arm 41 which is rotatably mounted in the intermediate lower part of the frames 21 a and 21 b, and a cam lobe 42 fixed coaxially on the axis of the input pinion 31 L the front end of the rotary arm 41 is engaged with the articulation 5 (see FIGS. 2 and 3) and the rear end of the rotary arm 41 is engaged with the cam lobe 42 With the rotation of the rear wheels 10, the pinion d input 31 and the cam lobe 42 are rotated by means of the axis 36, and the rotary arm 41 comes into engagement with the large diameter part 42 a and the small diameter part 42 b of the lobe of cam 42, thereby rotating the rotary arm 41 in a vertical direction When the rotary arm 41 rotates, the joint 5 which is in engagement with this rotary arm 41 also rotates, thereby rotating the front outer shell 2 in a vertical direction so to activate the goat he of the hippopotamus between the half open position and the position

wide open.

  The film forming mechanism 23 has a bevel gear 51 for forming the film of soapy solution, a force transmission shaft 52 having the bevel gear 51 fixedly mounted on the front end, and a pinion 53 so mounted fixed on the rear part of the power transmission shaft 52 The pinion 53 engages with a worm screw 54 fixed on the same shaft as the first intermediate pinion 32, functioning as a worm and a worm wheel end in order to slowly rotate the bevel wheel 51 via the force transmission shaft 52 The bevel wheel 51 has several sector-shaped openings 55 in a circumferential direction in the edge area, half submerged in the soapy solution in the solution tank section 8 and directed outward into the mouth of the hippopotamus as shown in Figure 1 The bevel wheel 51 produces a film of solut Soapy ion in each of the openings 55 while rotating The fan mechanism 24 blows on the film of soapy solution in order to make bubbles S. The fan mechanism 24 has a housing 61 formed outside the chassis 21 a, a body fan 62 housed inside the housing 61, and an exhaust plug 63 intended to conduct the air blown out of the housing 61 to the openings 55 of the bevel wheel 51 The housing 61 consists of a body 61 a protruding outside the frame 21 a and a cover 61 b intended to cover the lateral face of the body 61 a in order to form a space in the housing 61, and has an air suction orifice 64 in the center of the cover 61 b. The fan body consists of a turbine section 65 and the main shaft 66 on which the turbine section is fixedly mounted The end of the main shaft 66 is freely rotatably mounted on the pinion outlet 35 passing through the frame 21 a Between the interior of the frame 21 a and the output pinion 35 is a collar 67 and a coil spring 68 which are all

  two mounted coaxially with the output pinion 35.

  Behind the output pinion 35 is a clutch

  in the form of a crown 69 fixed to the main shaft 66.

  The clutch 69 and the output pinion 35 each have teeth on opposite faces, and are held in engagement with one another by the force of the helical spring 68 The rotational force of the output pinion 35 is transmitted to the crown-shaped clutch 69, from which force is then transmitted to the turbine section 65 via the main shaft 66, thereby rotating the turbine section 65 Therefore, in the event of increased inertia and resistance to rotation at the turbine section 65 when the turbine starts and stops turning, the output pinion 35 slides on the clutch 69, thus preventing excessive application of load on the train

drive gear 22.

  The drain plug 63 is installed so that it is connected to a bubble outlet 70 pierced in the front end of the interior of the housing 61 from the interior of the chassis 21a, and the air outlet 63 a formed in the front end part is presented from the inside in the openings 55 of the bevel gear 51 With the rotation of the output pinion, the turbine section 65 is driven in rotation via the shaft main 66, sucking air into the housing 61 through the air suction port 64 The air thus sucked in is blown through the air outlet 63 a from the exhaust plug 63 against the film of soap solution formed in the openings 55 of the bevel wheel 51, thus producing bubbles S. A series of movements of the toy to make

  bubbles will now be explained in order.

  When the toy body 1 is pushed, the rear wheels 10 rotate, and the rotational force is transmitted to the axis 36 The rotational force transmitted to the axis 36 drives the gear train 22 via the pinion input 31 and causes the opening of the hippopotamus to open and close via the cam lobe 42 and the rotary arm 41 The rotational force applied by the input pinion 31 to the first intermediate pinion 32 rotates the bevel wheel 51 via the endless screw 54 and the pinion 53 of the film forming mechanism 23 The bevel wheel 51 rotates in order to withdraw liquid L of soapy solution in the solution tank section 8,

  and a film of liquid is formed in the openings 55.

  The rotational force transmitted to the output pinion 35 rotates the turbine section 65 of the fan mechanism 24 at relatively high speed, blowing air through the exhaust plug 63 against the openings 55 of the bevel gear 51 The film soap solution in each opening 55 thus forms a bubble S which is blown forward The bubble S thus blown is discharged through the mouth of the

toy body 1.

  With the present invention, the bubble producing device 6 driven when the body 1 is moved discharges bubbles S through the mouth of the hippopotamus so that a child or another person playing with the toy to make bubbles can having fun with the toy while moving the body of the toy A unique toy that even a child can push in order to bubble without getting dirty

  hands with the soapy solution is thus provided.

  In the embodiment described below

  above, the toy for blowing bubbles has been described as being in the form of a hippopotamus The invention is not limited only to this embodiment and is also applicable to dolls, toy cars or boats- toys as well as

other toy animals.

  According to the toy for making bubbles of the invention, the bubble production means integrated in the toy body are driven by the connection with the wheels of the toy, and bubbles produced are discharged through the opening section of the toy body. toy The bubbles come out of the opening section in response to the movement of the toy body A new, interesting and extremely easy-to-use toy for making bubbles is therefore provided. Furthermore, the toy body constructed in the form of a animal and designed to evacuate bubbles through the mouth of the animal results in a very original and durable toy In addition, the use of a cam mechanism to open and close the part corresponding to the mouth of the animal produces an even more interesting and attractive toy because it moves in a realistic and unique way.
