Description

A kind of cupule head of hand-throwing toy and the sucker dartlike weapon of using this cupule head

Technical field

The present invention relates to a kind of cupule head of hand-throwing toy parts, particularly a kind of hand-throwing toy; The invention still further relates to a kind of sucker dartlike weapon of using this cupule head.

Background technology

At the twentieth century initial stage, be used in the impelling love toys at first with the sucker of natural rubber system.Toy boomerang and toy arrow that head has sucker have following distinct advantages: (1) sucker resembles a big and blunt rubber arrow, suctorial Toy boomerang is difficult for hurting sb.'s feelings when penetrating, thereby relatively provides suitable guarantee to the safety of the children in playing; (2) do not resemble the toy of other blunt nosed structure, the Toy boomerang or the toy arrow of band sucker can stick on the hard and level and smooth surface, therefore suctorial dartlike weapon type toy is than common pure toy, can provide more and good playing to be worth, thereby widely be applied in the toy product to the children in playing.

In the sucker toy in early days, the structure of sucker is a slice garden type and with the rubber of concave surface, along with the invention (as soft PVC and silicon synthetic resin etc.) of synthetic rubber and other elastic synthesis material, these materials also are used in the manufacturing sucker.The operation principle of sucker is when sucker impinges upon hard and level and smooth target surface with a subvertical angle, it is smooth that impact becomes the concave surface part, thereby with the discharge of the air in concave surface concave surface, make that the interior air pressure of the concave surface air pressure outer than concave surface is low, the pressure of atmosphere makes sucker be pressed on the surface of being clashed into by lock.Have only when air leaks and enter the air pressure that makes in the sucker inside and outside the sucker and reach to balance or during near balance, the weight of toy itself makes sucker be come off by the surface of adhesion.

The sucker of tradition rubber or elastomeric material manufacturing can be accomplished very good through improvement performance for many years, but it is used in the toy product, has then still had some shortcomings and need have been improved part.After long-time statistical is observed, sum up following some:

(1) sucker made from traditional material, good to the function that the target surface (as window-glass, refrigerator iron gate etc.) of hard and flat-satin is adhered, but for the surface of semi-flat (as cement wall, japanning and without the timber of polishing etc.) and smooth and more coarse inadequately surface, the sucker that traditional material is made because of can not with this type of surperficial intact applying, cause absorption bad so that can't pin the inside and outside draught head of sucker, therefore sucker one be fully can't sorption at target surface, maybe can only stop once very fast disengaging to two seconds.The very big limit of this characteristic ground has limited to the place when children are at play the sucker type toy, has also limited to the value of playing when children play simultaneously.

(2) based on above-mentioned reason, toys manufacturers design during sucker except that adopting traditional synthetic material more full of elasticity, more be conceived to the structural improvement of sucker, all ameliorative measures provide stronger suction really to the surface of hard and flat-satin, but not too smooth and coarse surface is not still had too many help.The well-designed sucker of traditional material manufacturing has but brought another problem, when children are at play with the impelling of sucker toy when the object of hard and flat-satin (as window-glass etc.), because of the suction of sucker powerful, the sucker toy can rest on the target surface a few hours to a couple of days, this is for often keeping the head of a family in good order in the hope man, be the thing that to accept, therefore not welcome by the head of a family.

(3) in order to strengthen sucker that traditional material the makes adhesion strength to smooth and smooth surface, children generally understand water adhesional wetting sucker.Dirty but the moisture content on the wet sucker is easy to be stained with mud dirt, dirty sucker is easy to that (on as wall or on the ceiling) stays circular spot on surface its contact or adhesion.The idea of wishing to keep cleaning in the family not have stain because of this situation about often having and the heads of a family is not inconsistent, the toy of sucker class thereby can not get the head of a familys' favor.

(4) sucker made from traditional material, because of the hardness and the flexible restriction of material itself, must be when impelling with a vertical or subvertical angle impelling with respect to target surface, sucker just can cling the surface in target like this.If to the target surface impelling, in most cases the sucker toy only may limit to the enjoyment value when children play like this by target surface underground can not the adhering on the target surface of rebound back with a less angle.

Solving the problem of the sucker dartlike weapon existence of above several somes traditional materials manufacturing, is the direction of toy industry technical development from now on.

Summary of the invention

The sucker dartlike weapon that the purpose of this invention is to provide a kind of cupule head of the hand-throwing toy that can overcome above-mentioned technical problem and use this cupule head.

The specific embodiment

The cupule head of a kind of hand-throwing toy of the present invention, described cupule head is made by flexible foamed synthetic material, the composition of this flexible foamed synthetic material comprises: 35%～45% polyvinyl acetate, 10%～20% ethylene vinyl acetate, 10%～20% acrylonitrile-butadiene rubber, 5%～15% polyethylene, 15%～25% calcium carbonate.Other cooperates an amount of blowing agent, foam stabiliser, thermal stabilizer, crosslinking agent foaming under the effect of catalyst.The combination of this composition adds the flexible foamed synthetic material that suitable foam process is made, has light weight, softness, high resilience, is easy to bending and has the faint gas permeability of controllability, and these characteristics are very important to the function of cupule head.In addition, the cell diameter of described flexible foamed synthetic material is less than 0.2mm; The abscess ratio of described flexible foamed synthetic material is 5%～10%.

Except adopting traditional rubber and elastic synthesis material to go to make the cupule head, the expanded material (SoftCloseCellFoam) of soft CAB structure is considered to unique feasibility material that may be used to make cupule head, because the bubble structure of its closure makes air not penetrate and can keep the sucker sorption.But to be material hard partially and elasticity is not good for the main shortcoming of most enclosed construction expanded material, form during the cupule head impelling adhesion of therefore making with these materials block bad so that can not or only momently sorption on target surface.At this shortcoming, the present invention is in particular and addresses these problems, select novel synthetic material for use and allocate new foaming formulation, make a kind of novel flexible foamed material (SoftCloseCellFoam), use the cupule head of this new type soft foamable synthetic material manufacturing, can meet the requirement that the required material behavior of improvement cupule head function provides substantially.This its physical characteristic of new type soft foamable synthetic material is as shown in following:

(1) hardness of new type soft foamable synthetic material is controlled at 30 ° or following (being as the criterion with soft rubber or expanded material hardometer).Its height soft characteristic provides sound assurance for the security of toy.

(2) cell diameter of new type soft foamable synthetic material is controlled at below the 0.2mm, makes its surface can meet the requirements of smoothness.The dense property of its abscess makes the function of its envelope gas that strong condition is provided.

(3) the new type soft foamable synthetic material has excellent elasticity, makes its reinstatement soon after distortion.The resilient engagement highly-flexible degree of its height makes its envelope gas adaptability to coarse surface, provides feasible property that sound assurance is provided.

(4) foam structure of new type soft foamable synthetic material belongs to the enclosed type foam structure basically, but make under the suitable adjusting on the modulation of foaming formulation and foaming operation technology controlling and process, the foam structure of this material is controlled at and contains 5% to 10% Open architecture.The characteristic of this type foam structure for its can be in a period of time the entering of blocks air, but a spot of open foam structure can allow air infiltrate through in the sucker lentamente under the atmospheric pressure effect, make sucker especially as timer is housed, come off automatically after adhesion a period of time at target surface.

The contact end face 11 of described cupule head is provided with sphere pit 12, and the degree of depth of described sphere pit 12 is 5%～20% of contact end face 11 diameters, and the diameter of described contact end face 11 is 1/4th of sucker dartlike weapon length overall at least.The side profile of described cupule head is a S shape hyperbola.The cupule head external form adopts the hyperbola cylinder external form of approximate English alphabet S, the material of making cupule head adopts above-mentioned flexible foamed synthetic material, the double-decker that the top adopts high density and high rigidity expanded material to be bonded, the bulk shape of cupule head is as a hemisphere, be used in combination the material behavior of the softness of flexible foamed synthetic material, full of elasticity, little gas permeability etc., therefore the cupule head that produces has following characteristic:

(1) appearance structure cooperates the characteristic of material, and the impact that causes when making cupule head absorb impelling effectively plays very good buffer action.Provide prerequisite advantage to sticking suction of cupule head at target surface, the while also provides more sound assurance for the security of toy.

(2) made full use of the material characteristic of flexible foamed synthetic material because of appearance structure, this cupule head not only can be inhaled effectively and be bonded at hard and surface flat-satin, can inhale equally not too smooth and coarse surface (as cement wall, boarded door etc.) and glue in its surface.

(3) the flexible foamed synthetic material of manufacturing cupule head has little gas permeability, so characteristic, even inhaling, this cupule head is bonded on very the surface of flat-satin (as window-glass), after after a while, it can automatically be come off by the surface because of the slowly infiltration of air, time, the length of time was determined by following essence by between several seconds to the one minute kind: a. is directly proportional with the smooth and smoothness of inhaling sticking target surface; The open abscess ratio that control generates when b. making with material is inversely proportional to; C. the ratio with cupule head and sucker dartlike weapon entire length is directly proportional.

(4) appearance structure cooperates the characteristic of flexible foamed synthetic material, make this cupule head head-on collision prick the surperficial good adaptability that is attached with, when this characteristic makes under situation about having angle with target surface impelling, as long as the angle of impelling rule mark and target surface is not less than under 35 ° the situation, cupule head is bonded on the target surface to inhale near hundred part of 95 above ratio.

(5) just towards the target surface impelling time, this cupule head only need have the 80 percent above area of surpassing to contact with target surface, and cupule head can well have been inhaled and be bonded on the target surface.This almost is the thing that impossible take place concerning the cupule head made from traditional material.

A kind of sucker dartlike weapon of using described cupule head, comprise cupule head 1, cupule head 1 top is connected with provides the boomerang of gripping body to shake hands 2, and the boomerang body is shaken hands and skeleton 3 is installed in 2, this skeleton 3 its end that stretches out is equipped with and decides the wind wing 4, and described cupule head 1 and boomerang body are shaken hands and be bonded with reinforcement 5 between 2.Have shrinkage pool 51 on the described reinforcement 5, be fixed with in this shrinkage pool 51 and weigh down heavy box 52, weigh down and be placed with metal drops in the heavy box 52 and weigh 53, the heavy box 52 of described bob is connected with the head end of skeleton 3 by weighing down heavy box top cover 54.

Described boomerang body is shaken hands and is had the centre bore 21 that runs through its upper and lower end face in 2, and described skeleton 3 is positioned at this centre bore 21, and shake hands 2 surface of boomerang body is provided with and makes it be some annular grooves 22 of organ Zhe formula structure.The end of described skeleton 3 is provided with latticed protruding 31, describedly decide the wind wing 4 by assembling tube 41 with decide wind fin 42 and form, this assembling tube 41 is made up of two cylinders, each cylinder tail end extends the flat pad 43 of wearing burr of a slice, and these pad 43 inboards are provided with and these latticed protruding 31 grooves that match 431.The outer cover of described skeleton 3 is equipped with braiding webmaster 6.

With reference to Fig. 1, Fig. 2 and Fig. 3, shown a kind of sucker dartlike weapon of the present invention, comprise that the bulbiform boomerang body of cupule head 1, organ Zhe structure that flexible foamed synthetic material is made shakes hands 2, the skeleton 3 of plastics, expanded material are made decides the wind wing 4, be sleeved on the boomerang body shake hands on 2 braiding webmaster 6 totally five main partly cooperatively interacting combine.Each partly main characteristic and function division is as follows:

Cupule head 1 is bonding with the reinforcement 5 that is arranged on cupule head 1 top, cupule head 1 has large and inwardly is the sphere pit 12 that sphere caves in, when hand is thrown the sucker dartlike weapon when target face is dished out, metal drops weighs 53 and decide to be directed at cupule head 1 under the interaction of the wind wing 4 and turn to the place ahead, and the result is that the contact end face 11 of cupule head 1 is the face of contact target face at first.Cupule head 1 is the emphasis of the present invention's invention, and its main characteristics has following several:

Cupule head 1 has adopted novel flexible foamed synthetic material manufacturing, and the Main Ingredients and Appearance of material and its unique property are described in detail in foregoing.The unique property that is had because of the new type soft foamable synthetic material, but make and adopt cupule head 1 sorption that this material makes in most target surface, comprise not too smooth and slightly coarse surface.The also uniqueness of material simultaneously is even sorption on extremely smooth and smooth surface, can be voluntarily after through one controllable period be come off by the target face of sorption.The spherical structure of contact end face 11 for caving inward of cupule head 1.When hand-throwing thing toy is dished out and is impinged upon target surface, this sunken inside spherical structure can make the shape of contact end face 11 faster and better adaptation target surfaces and become smooth, the air that discharge includes causes external and internal pressure poor, make cupule head 1 immediately sorption at target surface.

The diameter of the contact end face 11 of cupule head 1 is 1/4th (25%) of a sucker dartlike weapon total length, change the diameter of contact end face 11 and the ratio between the sucker dartlike weapon total length, can well regulate intensity and the time of cupule head 1 sorption at target surface, the diameter that contacts end face 11 of the intensity of sorption and time and cupule head 1 is directly proportional, and meaning promptly contacts the big more intensity of end face diameters and the time is strong more and length.

Sphere pit 12 degree of depth of the contact end face 11 of cupule head 1 are 1/10th (10%) of contact end face 11 diameters, this ratio can make contact end face 11 fade near smooth when the bump target face, and the area near 95% is discharged air and produced suction attached to target surface.The depth value that changes sphere pit 12 can be regulated cupule head 1 sorption character, and the suction to smooth and smooth target face when the degree of depth of sphere pit 12 strengthens (greater than 10%) increases, coarse surperficial suction is reduced.When otherwise the degree of depth of sphere pit 12 reduces (less than 10%) smooth target surface suction is reduced and coarse target surface suction is increased.But the degree of depth that increases and reduce sphere pit 12 has a limits, and at it between 5% to 20%, too small or cross the function that senior general has influence on cupule head 1, the serious cupule head 1 that can make lost efficacy its scope for the diameter of contact end face 11.

The side profile of cupule head 1 is a hyperbola that is similar to English alphabet S, this structure is except that producing when cupule head 1 strikes target surface the good cushioning effect, more can be by changing the height of hyp radian and cupule head 1, the control air enters the distance of contact end face 11 required processes, because of cupule head 1 has been selected the manufacturing of new type soft foamable synthetic material for use, the ventilative character of the trace of this material, when cupule head 1 sorption during at target surface, see through control outer room air leaks and go into to contact the distance of end face 11 required processes, can regulate cupule head 1 by sorption to the needed time length that comes off automatically, need the big more sorption of distance of process long more to the required time that comes off, the time that means cupule head 1 sorption is long more, otherwise then short.

The reinforcement 5 at cupule head top uses density and all bigger semi-rigid expanded material (EVAFoam) of hardness to make, with seccotine stick and cupule head 1 good bond.Adopt this one hard one soft structure that two effects are arranged; The reinforcement 5 of one hard can be well when cupule head 1 impinges upon target surface passes to whole of contact end face 11 of cupule head 1 to impulse force fifty-fifty, makes that cupule head 1 can the more effective target surface that holds; Its two impulse force that can absorb remainder plays cushioning effect.

The top of reinforcement 5 has a columniform shrinkage pool 51, and the main effect of shrinkage pool 51 is that the fixing metal drops of weighing down heavy box 52 and weighing down in the heavy box weighs 53, the protection metal drops weigh 53 can be when not playing continuous impelling bump by deviating from the main body; Also play simultaneously skeleton 3 fixing and each effect partly of connection that make.

The boomerang body is shaken hands and 2 is fashioned into approximate more than half rugby of bulbous external form, and its centre bore 21 is that a circular hole above-below direction penetrates whole boomerang body and shakes hands 2, and the boomerang body is shaken hands and had annular groove 22 more than 3 on 2, causes approximate organ Zhe formula structure.Shake hands 2 bulbous external form of boomerang body can easily be caught and launch, and 22 of annular grooves can be strengthened boomerang body shake hands 2 gripping power and comfort feel are also played the effect of gimbal suspension simultaneously, this can after explanation.Shake hands 2 composition surface of boomerang body sticks with glue firm being bonded together in composition surface of agent and reinforcement 5, and 3 on skeleton passes shake hands 2 centre bore 21 of boomerang body and stretches out, and makes that cupule head 1, reinforcement 5, boomerang body shake hands 2, skeleton 3 connects into an integral body.

Skeleton 3 mainly act as support and connects each parts.Skeleton 3 by cross bone bar, weigh down heavy box top cover 54 and weigh down heavy box 52 and form, material selection gathers third vinyl plastics (PP), gets the toughness that has in its rigidity to a certain degree and is difficult for splitting off.Cross bone bar is the plastic bar of conical structure, is connecting reinforcement 5 one end diameters greater than the diameter of decide the wind wing 4 one ends, and this spline structure can make in cupule head 1 one ends enhancing impact resistance intensity, but afterbody is decided the wind wing 4 one ends and kept accommodating certain elasticity; The section of cross bone bar is the cross network structure of ashamed change from large to small, can keep due requirement of strength simultaneously under the condition that the minimizing materials reduce cost like this.The button hook seat of cross column type is right after together with cooperatively interacting; Cross bone bar is near deciding the wind wing 4 one ends.Weighing down heavy box 52 is combined together to form space placement and protects metal drops to weigh 53 via fixing pin and the heavy box top cover 54 of bob; weld together with weighing down heavy box top cover 54 weighing down heavy box 52 with network iron or ultrasonic wave, provide better security protection order metal drops to weigh 53 and can not deviate from easily.Metal drops weighs 53 and uses flattened cylindrical shape discus structure, adopts this shape based on 2 reasons, and one is dispersed to not making children be injured the degree that article damage (as breaking up windowpane) impact for increasing the area of striking face; It two shifts to cupule head 1 one ends for Jin amount makes the center of gravity of sucker dartlike weapon, goes out sucker and darts with which kind of method (comprise end to end and being inverted) impelling no matter cooperate the orientation of decide the wind wing 4 to make, can flying with cupule head 1 direction forward near one of percentage hundred.

Decide the wind wing 4 by assembling tube 41 with decide the wind fin and partly form for 42 liang, the expanded material that material use proportion is lighter and through mould molding.Assembling tube 41 is synthetic by upper and lower two symmetrical cylinders, and the center is done with skeleton 3 identical grooves 431 and is used as and skeleton 3 bonding and location, and tail end extends the flat pad 43 of wearing burr of a slice, is bonded in tail and shakes hands the two sides as the anti-skidding purposes of cushion.Deciding wind fin 42 has three, uses mould molding, and there are sculptured decorative pattern and pictorial trademark in the two sides, welds on assembling tube 41 peripheries with heating power, and space 120 degree are used for that guide effect makes it with cupule head 1 direction flight forward when dishing out the sucker dartlike weapon.

Braiding webmaster 6 is a pipe box that is formed by polyethylene wire drawing braiding, and braiding webmaster 6 is main in the sucker dartlike weapon to produce following effect: make its outward appearance more attractive in appearance as the coat of skeleton 3; Sticking with glue agent connects the boomerang body and shakes hands and 2 with the assembling tube 41 of deciding the wind wing 4 whole bond strength is further strengthened; The elasticity of the good telescopicing performance better fit skeleton 3 of braiding webmaster 6 obtains cushioning effect.

Fig. 4 and Fig. 5 show that cupule head 1 before the bump object table and hit schematic diagram after pricking target surface, takes this characteristic and the operation principle of exemplary illustration cupule head 1.Cupule head 1 uses novel flexible foamed synthetic material manufacturing, the soft and band elasticity of this material character, and the fine and closely woven and gas permeability of band trace of foam structure, these characteristics are extremely important to the work behavior of cupule head 1.Fig. 4 show for when cupule head 1 residing state at a moment before impinging upon target surface, contact end face 11 and outer lonely face all remain on normal form, what target surface showed is a comparatively coarse surface.What Fig. 5 showed on average disperses impact to be passed to by outer lonely face and contacts end face 11 for cupule head 1 bump sucker top reinforcement 5 and metal drops weigh 53, the target surface that makes contact end face 11 and hit coincide together closely and compresses cupule head 1, produce two effects in a flash at this, at first absorb the impact that has produced when having eliminated impelling, make the sucker dartlike weapon halt immediately and no longer move at target surface; Thereby simultaneously, the characteristic of the material used drains two air between face because of making contact end face 11 and target surface coincide with the ratio that is similar to one of percentage hundred, the inner and outer air pressure difference that produces allows atmospheric pressure that cupule head 1 is pressed on target surface, even target surface be a conventional suction cups can not sorption rough surface, also immediately sorption on target surface.After this takes place, little gas permeability of new type soft foamable synthetic material begins to work, air is infiltrating between the open cells by material under the effect of atmospheric pressure, inside and outside draught head Zhu Walk reduces, the weight of Da sucker dartlike weapon to a certain degree time the and the elasticity of cupule head 1 material act on down simultaneously, make sucker dart automatic breakaway surface.

Fig. 6 shows be when the sucker dartlike weapon with narrow angle to the target surface impelling, the continuous action demonstration of sucker dartlike weapon when striking target surface.1. show among Fig. 6 and work as the sucker dartlike weapon to be not less than the situation in a flash that 35 angles of spending impinge upon target surface, cupule head 1 contacts with target surface to be an angle.The crucial key action for taking place in a flash down 2. shown among Fig. 6 changes; At first, material (new type soft foamable synthetic material) the soft full of elasticity characteristic of cupule head 1 because of using, impact is promptly coincide a part of contact end face 11 with target surface, thereby producing suction and gripping power stops the sucker dartlike weapon to bounce-back in the other direction, also absorbed simultaneously most impact, remaining impact is decided the wind wing 4 unceasingly to preshoot with the form order of inertia, the elasticity that had of the vertebra type structure of skeleton 3 and boomerang body 2 the organ Zhe structure generation effect simultaneously of shaking hands at the moment, air makes skeleton 3 bendings offset remaining part impulse force to the resistance of deciding wind fin 42; 2 the organ Zhe structure of shaking hands the boomerang body plays the effect of gimbal suspension, makes the reinforcement 5 at cupule head top change angles, thereby remainder is not continued to press to target surface and produces suction with the end face 11 that contacts that target surface coincide as yet.Among Fig. 6 what 3. show is when all impacts are offseted after, the elastic force of skeleton 3 makes sucker dart reinstatement and stands on target surface.

What Fig. 7 showed is behind target surface in the sucker dartlike weapon bump, but contact end face 11 has only the situation demonstration that partly contacts with target surface when coincideing.Particularity because of the new type soft foamable synthetic material, also can produce suction though have only part acting surface and target surface to coincide, but suction can be along with the change that is directly proportional of contact area, as long as contact-making surface Da to percent 80 or more than, suction will be enough to support whole sucker dartlike weapon, the percentage size of required contact area is along with the smoothness of target surface is inversely proportional to.

In real example, a child who holds the sucker dartlike weapon in the example can be with the impelling of toy sucker dartlike weapon in any wall, ceiling, door and window, floor, no matter the roughness of wall etc. or smoothness come off after the sucker dartlike weapon can cling a period of time automatically.

Just one of them embodiment of the present invention that foregoing is showed can also use similar structure to draw a lot of other different embodiment.For example, the sucker dartlike weapon can have longer skeleton and become arrow; Sucker dartlike weapon is removed and is decided the wind wing and as javelin.Moreover, other parts such as bulbiform boomerang body shake hands 2 and the cross type profile structure of the skeleton 3 of its organ Zhe structure, vertebra type etc. all may have difference in the configuration design.All difference, change and similar embodiment roughly the same should be included within protection scope of the present invention.
