Abstract

A hinge device and a method of manufacturing the same, by which letters can be pivotally connected to form alternate alphabetic character forms according to the positions of the letters in words. The device comprises a female element and a male element which are integral with a letter element linked together.

Description

Hinge means and member manufacturing method thereof

Technical field

The present invention relates to a kind of a kind of mechanical hook-up that some alphabetic element that constitutes Arabic alphabet table teaching aid is linked.

Background technology

Usually the teaching aid of notion existing description in GB2244842.28 letters are arranged in the Arabic alphabet table, and according to the position of these letters in word, each letter all may be in beginning, centre, the end of word or the character style of separating.If do not consider that position, some characters can be identical, some characters can have two kinds multi-form, other character four effects each on, different character styles can be arranged.Also have some principle to stipulate which letter can maybe can not be right after other letter.GB2244842 has described a kind of method, by first parts being linked and/or by extra parts are added in first parts, some characters in the alphabet can be represented (as rigid plastic) by first parts separately, and remaining character is then formed by these first parts.These parts have the different structure (as groove) that makes parts or the correct link of character.

Summary of the invention

Here describe a kind of hinge means and manufacture method thereof, utilize this apparatus and method, place letter pivot to form alternately character according to the position of this letter in word.

A first aspect of the present invention provides a kind of hinge means that articulates the alphabetic element in the Arabic alphabet table, and each letter comprises at least one alphabetic element, and hinge means includes:

A protruding element and a recessed element;

Each described protruding element and recessed element and the described alphabetic element monolithic molding that is connected with each alphabetic element, therefore,

The recessed element of one alphabetic element that separates and the protruding element of an alphabetic element are meshing with each other, thereby can articulate the part of described alphabetic element, to form the character style that replaces of described letter according to the position of letter in word.

A second aspect of the present invention provides as the described hinge means of above-mentioned first aspect, wherein, described protruding element comprises: one outstanding and be cast as holistic axle with alphabetic element from alphabetic element, the sleeve pipe that can be installed on the axle, a plurality of in the formation of the ends of protruding element and from the extended dog of axle, each dog has an effective slope and the groove in formation around the zone of the outstanding axle of alphabetic element;

Recessed element comprises: the bigger axle of diameter of the inside part; The effective slope that the part of two different-diameters of axle is coupled together is linked at a time-out at the alphabetic element separately of recessed element and protruding element, and this slope leans against on the slope, side of corresponding protruding element; A wheel rim that forms around the openend of axle, it is arranged in the groove of recessed element during use.

It is a kind of by the method for two parts mould manufacturing according to the protruding element of the described hinge means of above-mentioned first aspect that a third aspect of the present invention also provides, and may further comprise the steps:

Each of mould partly is installed on the opposing face of casting machine;

On the casting machine, each of mould is partly orientated as correct direction;

Fluent material is introduced in the casting machine, from mould, formed protruding element;

With mold cools down;

It is characterized in that: the two halves mould has a slidably spindle unit, and this method is further comprising the steps of:

Slidably axle by sliding mould on the dog that leans against protruding element take out the protruding element of making from mould, thereby hook can take out protruding compression element to enough little diameter from mould.

Element that link is got up and alphabetic element casting itself are in aggregates.Each hinge comprises one " recessed " and " protruding " element, and they integrally are cast in the element that is linked at together.This global design has reduced the complicacy of processing and manufacturing, has reduced assembly cost.This design can also allow not the built-up member piece and sell, thereby can oneself assembling.These elements are easy to carry out manual setting.

This integral hinge design, the user can also be disassembled into parts to letter, thereby utilizes alphabetic element to constitute the shape that does not form alphabetic(al) letter.Non-detachable permanent fixation hinge has stoped the polyfunctional appearance that can allow the second important pattern.

Although it is very important that element can be dismantled, in case these elements link together, to keep firm connection also be very important to these elements in the use.Unite the letter character that forms by two or more elements and be used for clearly being familiar with a letter character, become its building block if a letter character is dismantled easily, it just can not carry out its function.Because " protruding " element of hinge must break away from mould in casting technique, thereby make the making of easily detachable hinge not complicated.

The element that another one is used with hinge is to its a kind of mechanical hook-up that positions when two elements of a letter rotate into correct toward each other position.By " flip-flop " being set reliably or " " or the both has, and can finish this location to cough up crash sound.The means that this assigned direction that presses and/or click the element that can get up as two links of indication the position is proofreaied and correct one of them character style of this letter.

Embodiment

Hinge " being recessed into " half in shape must be to be used for making " protrusion " half mould similar.This just means in case element is assembled and can not pull down " protruding " element from mould, just must find a kind of half measure to make " protruding " element break away from " recessed " connection.The sectional view of " recessed pawl " as shown in Figure 1, it has enough hardness to come the hinge of assembling is fixed together, and does not need exceedingly to be out of shape or come off fully and just can break away from mould.In the commodity production process of element, any destruction in the mould does not obviously wish to occur.Fig. 2 and Fig. 3 describe " protruding " element and " recessed " element respectively in detail.The main shaft 4 of " protruding " element has a dog 5 in the terminal of each " protruding " element as shown in Figure 2.Hook 5 has movable slope, side 6 on the gradient 7 that leans against " recessed " element shown in Figure 3.The diameter of main shaft 4 is less than the diameter of the lining 8 that allows " protruding " element to be rotated in " recessed " element.Only " protruding " thus element axially on apply enough power and main shaft element 4 inwardly bent when shifting out the gradient 7 along the gradient 6, just may pull out " recessed " element.The retroaction that elasticity produced that opposite with this action is by the material and the sleeve pipe 14 of main shaft 4.Thereby final main shaft element 4 is subjected to enough big pressure makes hook 5 slip over lining 8.In the bottom of " recessed " element a wheel rim 10 is arranged, it is positioned at the groove 9 of the bottom of the main shaft element 4 that is arranged on " recessed " element, is used for firm connection when Connection Element.

In order to produce alphabetic element, select easy two part moulds, thereby reduce the making and the production cost of mould.Two parts are exactly that mould is divided into two five equilibriums basically.Each partly all is installed on the opposing face of simple and easy casting machine.Be appreciated that each partly all is made of one or more parts.Fig. 5 has illustrated half of instrument of the fixed part of " protruding " element that is used to make letter.

The user guarantees that the correct orientation of the element 3 of a character is very important.Owing to be positioned at correct direction, this can realize by setting " coughing up crash sound ".This is clicked indication that mechanism must provide a strictness and shows and arrive correct position that this indication is uncertain to be so stable so that can stop hinge easily to rotate to its next tram.Shown in Fig. 3 and 4, this locking mechanism needs one and installs to protruding half one of hinge and ridge 11 and groove 12 parts in the translational surface between recessed half one.This ridge 11 and groove 12 have formed the part of pressing and/or clicking element.If the hinge rotation breaks away from " correctly " position, just by force the main shaft element 4 of " protruding " pawl is lumped together, ridge 11 is thrown off from corresponding groove 12 by force, two parts are broken away from.Upwards drawing " protruding " pawl and partly breaking away from the half of hinge " being recessed into ", the main shaft element 4 of " protruding " pawl is subjected to the tension force effect, when the main shaft element 4 of " protruding " pawl arrives new detent 15, just very fast two parts is recovered in aggregates.In the rotary course of " protruding " pawl between the tram, mention,, only just can untie with easily making hinge fraction with very little power in correct position from half of " being recessed into ".Therefore the ratio on slope 6 and 7 is very important.In addition, the ridge of this mechanism is become with groove design to keep its durable under the situation that hinge repeats to open.The intensity of this " recessed " pawl must be enough big, thereby can be not tired because of repeated use, but also provide enough big power to compress hinge it enclosed the position of " correctly ".Be understood that if ridge 11 contacts with the end of groove 12 the relative rotation that the end of groove becomes an obstacle and stops element 3 to be done outside the hope.Alternatively, if the groove setting is very shallow, when ridge is corresponding with groove, crash sound only occurs coughing up, element 3 just can revolve three-sixth turn.

Thereby character can also be made amendment and be allowed character formerly to be connected with it.Each character in 28 alphabets can utilize the square-section plug that is positioned at alphabetical rear portion that it is made amendment.The placement of this stopper can make the hole, square-section of front letter can utilize interference engagement to be connected with it.Is opening in hole, distal-most end square-section at stopper.In this manner, otherwise when two letters all sliding together their in one plane the time, or this letter that is connected on the letter of front put into the tram from above, thereby these two letters linked together.Naturally, any connection in these two kinds of methods all is possible.All there are two thin-walleds in the hole, square-section at the either side of openend, and these walls couple together the alphabetical main body of the 3rd enclosure portion that forms the hole, square-section.Is not opening in the bottom in this hole, but sealing.Be designed to this connection, the hole, square-section can be said to a hand.Each wall of formation finger is shown as the finger more than three in the bottom of square opening.The bottom in hole, square-section is capped, and this returns wall increases extra intensity, and produces a more manageable interference engagement.

Connection between two letters is to make a letter be connected to the interference engagement of next letter from top according to the sequential write of Arabic alphabet, this being connected between all letters all is identical generally, therefore can be connected in 28 alphabetic character positions any one by other character is made amendment.This connection between two letters can be mentioned the two or more characters that link together and move, and can not separate easily, be just can separate letter easily with very little strength but interfere at this moment.

Utilization is middle and do not hold the letter " Ha " of combining form, can enumerate a very important connection example.Be in 90 examples of spending at these two, must use identical interface in this letter.This just needs a coupling arrangement, revolves when turning 90 degrees and can equally normally work at it.The connection that comes to this shown in Figure 7.

What deserves to be mentioned is the design of the coupling mechanism of the character style that is used for letter " Kaf ".This alphabetical character is made of four elements.Wherein two elements must correct according to a kind of like this mode, make it a hand interface occur in the release position.Yet when hinge rotated to detent position, for example apart from release position 180 degree, two identical elements also must correct so that they can just in time be loaded onto mutually, " hand " isolated approach the square-section plug.This plug is identical with the distance with hinge on other element with the distance of hinge on an element.Need in addition an element be folded in fully another element below, not only can obtain correct character shape like this, but also can isolate the plug on the described element.When being positioned at this character position, letter can prevent like this that previous letter is connected with the incorrect of this plug.In case utilize old plug that character transformation is arrived correct reposition, second easy to be approaching plug that is used to connect just arranged in this letter.What need in addition, is not only an inaccessible plug.The hand that covers this plug also must be inapproachable.Reason is to use this principle when recognizing these letters, if a letter has a hand, holds a tail at the end of letter.For letter " Kaf " this situation, that letter at the end of a word has an open hand.Yet this letter changes its shape, makes it look like a tail.Must hide its hand according to above-described mode in order to do it like this.Solve this utmost point laboriously the method for problem to consider following some.Two elements must correct, and they are turned to together.Because two elements that under normal circumstances turn to together should form a connection, and will clash into the plug of another element at " hand " wall that an element lifts, thereby prevent that these elements from sliding mutually, this point is problematic.Also has the another one difficulty.Prevent that by normal mode overlapping hand and plug member from locking together, can prevent that like this them from disconnecting by the similar rotation that makes their contacts.

When these two elements slipped over mutually, these two elements demonstrated this and show that they have arrived tram identical " coughing up crash sound ".

The more important thing is, must remember because this alphabetical special requirement and distich taps into capable correction that the character (for example " Kaf " character does not have " hamza ") that forms at the two elements of extended position must be able to be linked to another similar character.

The way that addresses this problem deducts almost half at the wall thickness of a side of " Kaf " " hand ".Thick this letter that still can guarantee of this half is connected with the effective of any other letter.And this wall has a seam that cuts off main body near the main body of letter.Common wall not only its thickness is approximately reduced by half but also length also reduces by half.It fixes other letter even now with still enoughly being plugged with effect.The seam that cuts off alphabetical main body allows fill in accordingly on another element, and plug must slide and make at least that the plug of another element becomes standard length like this, and the plug of remainder must partly excise and make the wall of half length skip it.This fact that were it not for is that (for example showing with wrist-watch) this character must be able to be linked on the similar character when opening at hinge, and the normal length of plug is reduced by half, and wall thickness reduces to half of normal thickness.Yet at this moment, two letters " Kaf " can't connect mutually.Adopt above-described method, on the hand wall, have enough plastics can face the plug that stretches out fully of similar character, thereby between two letters " Kaf ", form a desirable interference engagement.Because they just in time rotate to together before two elements are overlapping, on the contact point between two elements, make full use of the slight setting of plastics, so wall and plug do not reduce by half respectively.This setting is pressed on another element an element, makes them remain on detent position thereby set a lock.In case in position, similar slight setting just can make the compacting mutually in the other direction of these elements.Finally, by the rise of plug leading edge plastics and sweep (this part cuts the thickness of half approximately) are merged, when two elements slips over mutually, force and to break away from that element that has plug in that element bending of another element slip underneath.One tension force is arranged between two elements, just discharge tension force in case this two elements arrives the final position.This is used to emphasize to press and click the sensation that enters the tram.The important point that needs to understand is, because the letter plug just in time drops on the identical position with hinge in some cases, so the design of hinge and connection is not independently.This situation takes place once unlikely.At letter " Lam ", " Qaf " all has generation in " Nun ".Therefore hinge dimensions will have strict restriction, and it must be contained in the square plug of system of connections.Shown in Figure 8 is the structure of letter " Kaf ".

Correct letter according to a kind of like this mode, allow to insert a suitable magnet to the back side of letter, permission is used in combination this letter with metal or magnetic patch.

Connect and to say that becoming is a hand, so that according to the hand and the tail of letter, produce relation with the cartoon book and the story of the usage of subsidiary explanation letter.

Can use nontoxic/plastics of child safety, firm and durable are made element.Although can use other kind plastics, acetyl group is preferred a kind of plastics.Acetyl group has the low advantage of cost.Plastics must be strong and durable and also enough elasticity will be arranged, and make linkage can repeat work effectively.

Each letter generally is 8mm at its wideest point.This just means that hinge is very little.Big hinge needs big letter.Some consider that (such as the comfortable size of child's hand) is relevant with the size of selecting letter, and they do not have the too big piece of formation to the alphabetic element that uses in whole group together the time.When long word or expression can write on the A5 paper with these letters, their size was a particular importance.This fact is very important for the design of the subsidiary cartoon book of word module identical with material object on the display page.Must become to work effectively with this size hinge design.

Relatively easily make in order to be interpreted as what big letter, the accurate equipment in various industrial borders is allegedly arranged, use in the two elements mould, this mould can be emitted " protruding " pawl effectively, and this " protruding " pawl easy deformation or destruction in mould.Yet these equipment are difficult for using in little mould.
