Background technology

Since beginning to organize baseball game and league matches, the Baseball and Softball bat is just all used wooden the manufacturing.Wooden bat lathes and is processed into normal exterior dimensions and standard weights.In addition, the hollow aluminum ball-making bar occurred, obtained a lot of young athleticly liking that some regulations of some league matches and age group also require to use the hollow aluminum ball-making bar.In addition, hollow plastics bat also occurred, the sportsman of less age group uses hollow plastics bat in practising a ball game and training, and hollow plastics bat is generally used for lighter hollow baton round, rubber ball etc.

United States Patent(USP) Nos. 1,499,128; 1,611,858; 3,116,926; 3,727,295; 3,779,551; 3,811,596; 3,861,682; 3,955,816; 3,963,239; 4,241,919; 4,744,136; 4,763,899; 4,844,460; 5,114,144 and Canadian Patent No.962291 various bats are disclosed.

The major defect of solid wood ball-making bar is that price is higher, fracture easily in the use.Therefore, people are making great efforts a kind of ball stick made of reinforced wood of exploitation always for many years, in weight of being allowed and size parameter scope, its weight, size, intensity, rigidity and flexibility can both satisfy high-quality requirement, but service life is longer than the aluminum bat of standard solid wood ball-making bar or extrusion molding.For example, the diameter of qualified wooden bat must not be greater than 2.75 inches.

A U.S. Patent No. 3,129,003 that example is seen people such as Wheeler of this effort, wherein, a glass fibre cover tightly is enclosed within on the handle portion of wooden bat, fixes this cover with the plastic coating on this cover then.In the U.S. Patent No. 5,114,144 of Baum, make with foamed plastics or extrusion molding aluminium, be on the clavate inner core and cover the high strength fibre knitting or woven cloth of several layers with the resin dipping.And then cover the veneer that one deck scribbles resin, and then this compound is put into the mould that is made of two half modules, make resin solidification after the mould closes, thereby make a bat.U.S. Patent No. 3,598,410 disclosed a kind of wooden bats of Costopoulos comprise with the high strength multifilament thread and are wound on many thin slices in the surface groove along helix.At last, the U.S. Patent No. 5,301,940 of Seki discloses a kind of resin injection technology, a continuous reinforcing fiber and moulding material is attached on the outer surface of bat core of a usefulness fusible material or foamed resin preparation.

But the neither one patent disclosure is crossed the ball stick made of reinforced wood with feature of the present invention in the existing patent.Definitely say, the still unexposed a kind of like this reinforcement solid wood ball-making bar of prior art, the continuous cover that it is made a usefulness high strength fibre with resin is bonded on its whole outer surface.In addition, the still unexposed a kind of like this structure of prior art is in this structure, on the two-layer at least whole outer surface that covers a solid reel of a braiding cover.In addition, the still unexposed a kind of like this structure of prior art, in this structure, a composite high-strength cover is adhered on the surface of the reel that a size reduces slightly, the size of this cover equals the size that reel reduces, thereby makes the size wooden bat identical with the normal wood ball-making bar.

Summary of the invention

According to the present invention, prepare the solid reel of a dimension reduction, its shape is identical with wooden bat, and size is slightly smaller than the standard size of normal wood ball-making bar.This reel is supported on to cut on the lathe with the minor axis on it and forms.On this reel, cover one or more layers continuous applying fabric cover made from the high strength fibre silk, fiberglass braided cover preferably then, thereby form a preform bat assembly.Each layer fabric cover tightly is enclosed within on the whole outer surface of reel when forming the preform bat, and filament is arranged in the vertical in bat handle, thereby improves the intensity of this braid greatly.Then suitable curable resin, preferably be added in each layer of high strength fibre cover of preform bat assembly in room temperature or near the epoxy resin that automatically solidifies under the room temperature, this resin solidification, thereby each is pressed layer by layer, is adhered on this reel this cover, thereby generates the size bat identical with matched clubs.

In the preferred embodiment of the present invention, the diameter of fiberglass braided cover or other applying fabric covers remains unchanged on its length.The constant internal diameter of this of cover is slightly smaller than the diameter of reel rod-rod-body, is far longer than the diameter of reel handle portion.Supporting on the diameter available radial of this cover is big, with the pulling force on vertically or reverse and dwindle.Preferably, the filament of this cover and its longitudinal axis are into about+45 °/-45 ° angle.

Therefore, when being set to one deck cover on the reel, this cover struts in rod-rod-body slightly, thereby makes angle between filament and the longitudinal axis greater than+45 °/-45 °.Simultaneously, when on the outer circumference surface that every suit sublayer is enclosed within reel, can reverse or rotate reel relative to cover, make cover tension in the vertical, this reverses and makes cover shrink, thereby tightly wraps the outer end or the top of bat.Equally, the filament tensioning of handle portion or reverse makes cover tightly wrap the handle portion of bat.Importantly, this tensioning and a contraction that is enclosed within the braiding cover on the reel handle portion changed the direction of filament on handle portion.In fact, we find that when using a wired tube period of the day from 11 p.m. to 1 a.m, the direction of fabric fibre silk in handle portion becomes and more be interlocked near the longitudinal axis of bat, thereby the tensile strength of braiding cover on the longitudinal axis of handle improves greatly, and bat was the most weak in the intensity of handle portion originally.When with the curable resin lamination, when being adhered on the reel, filament is molded in the bat with this beneficial direction.This structure has improved the intensity of bat greatly.

The present invention also comprises a kind of unique manufacture method of above-mentioned novel bat.In general, this method at first uses the known bat making apparatus of lathe and so on one matched clubs bar to be made the core of solid molded bat.But for the present invention, the size of this reel whole outer surface is lathed the size that is slightly smaller than the normal wood ball-making bar, so that overlap the fiber glass coating sublayer thereon.In addition, leave the minor axis that is supported on the lathe on the reel.

Cut the some longitudinal flutings that are symmetrically distributed on the reel circumference in handle portion then, so that apply curable resin according to the present invention.Preferably, reel is treated and discharge air in the wood, the end agent of resinizing then on the reel surface.With a hollow bushing one or more layers continuous fiberglass braided cover is set on the reel then, thereby makes preform bat assembly.Be preferably in and put layer glass fiber cover on the reel., according to the present invention, this cover is enclosed within on the outer surface of this sleeve pipe, an end of cover seals on this opening of sleeve pipe for this reason.

The handle end of reel pushes in the openend of sleeve pipe, seals and the braiding cover is set on the reel from bushing outer surface thereby the handle end of reel props up this.Thereby cover tensioning in the vertical on being set to the handle portion of reel the time makes braid elongation and tightly being enclosed within on the handle portion.When in the whole insertion sleeve pipe of reel, the short supporting axle of excellent body end is rotated this reel as handle.This rotational action forces cover to tighten up on the outer end of reel and wraps the annular bottom surface of minor axis, and minor axis converges with the excellent body end of bat at this place, bottom surface.

Because the outer end that cover is wrapped reel, therefore, reel can be extracted out from sleeve pipe, and the cover on the reel does not unclamp or comes off when extracting out, and second layer glass fibre cover is set on the ground floor simultaneously.Stretch the then end of crossing kob of the second layer makes the second layer tighten up on the handle portion and ground floor of reel.This moment, this preform bat assembly can be for further processing.

According to the present invention, a kind of preferred molding process tightly is enclosed within known high shrinked plastic pipe on the preform bat assembly with thermal contraction.Then this collapsible tube as mould, with curable resin the fiber glass coating sublaminate, be adhered on the reel.This pipe preferably also shrinks with a suitable tubular elongate portion of excellent body end, and this elongated portion is as the container of accepting and hold resin, and resin before curing soaks each layer of glass fibre cover from flowing into lentamente this tubular die here.Because bat handle is different with the diameter of rod-rod-body, so the plastics molded tube shrinks, tightly is enclosed within this method on the preform bat assembly and be not only required in the thermal contraction process heating and shrink this plastics molded tube, and requirement this plastics molded tube that stretches simultaneously.Must carry out this and stretch simultaneously, the handle portion of tightly overlapping preform rod body assembly so that molded tube is shunk.

Preferably curable resin is slowly imported the tubular die then, so that soak each layer of glass fibre cover from this pipe elongated portion of tightening up.In addition, be preferably in and insert an ash tree batten in the resin of this pipe elongated portion as heat sink.Preferably also with air pressure force resin in due course between in soak each layer of glass fibre cover of preform bat assembly.

After soaking each layer of glass fibre cover, can be inverted the back to the preform bat assembly in the plastics molded tube and bat is clamped in the tight below of kob with anchor clamps.Like this, uncured resin and glass fibre can be full of handle/kob interface better.Resin is in case plastic tube-shape mould or thermal contraction shell are removed in curing.Polish the bat end face that exposes after cutting away short supporting axle then.Handle sandblast then makes handle seem coarse.

The specific embodiment

When the preferred embodiment of the present invention shown in the explanation accompanying drawing, use proprietary term for simplicity's sake.But, shown in the invention is not restricted to, described specific embodiments and selected term, and should regard as each proprietary term comprise all with the same manner work, realize technical equivalents things of same purpose.

As shown in Figure 1, the present invention strengthens bat 10 and comprises a reel 12 and a laminated product 14.This laminated product 14 is made of continuous, unbroken one or more layers applying fabric cover of the almost whole outer surface that covers reel 12.This cover with high strength fibre, preferably glass fibre is made, and preferably makes a braided fabric.This braiding cover floods with curable resin, thus this resin this strengthening layer or some strengthening layer laminations, be adhered on the outer surface of reel 12.

It is identical with the normal wood ball-making bar with physical characteristic that bat 10 is made into its size.Say that definitely the normal wood ball-making bar is made into various full-lengths, various standard weights and standard external diameter and shape, bat 10 is same by these standards making.The same with the normal wood ball-making bar, bat 10 comprises the kob 18 on proficiency shank 16 and this handle portion end, and the diameter of this handle portion increases progressively and converges with a rod-rod-body 20, and this rod-rod-body ends at a top or outer end 22.

Reel 12 is the same with the normal wood ball-making bar to form with lathe turning, also comprises the kob 21 on proficiency shank 17, a rod-rod-body 19 and the handle portion end.But as shown in Figure 2, the external dimensions of reel 12 is slightly smaller than the external dimensions of normal wood ball-making bar.In Fig. 2, the outline line of representing with label 24 that is shown in dotted line the normal wood ball-making bar, thus the external dimensions that reel 12 is shown is slightly smaller than the external dimensions of the bat of common standard size.After laminate 14 was adhered on the reel 12, the external dimensions of the ball stick made of reinforced wood 10 that is generated was just identical with standard size normal wood ball-making bar.Preferably, lathe is lathed reel littler about 1/10 inch than normal wood ball-making bar along the size of its whole length.Thereby, being about 2.50 inches normal wood ball-making bar for diameter, reel 12 preferably is about the 2.35-2.40 inch at the diameter of rod-rod-body 19.

In addition, when the reel 12 of turning dimension reduction on lathe, as shown in Figure 2, the longitudinal bracing

minor axis

26 and 28 that stretches out the special size on reel 12 two ends vertically remains untouched and is kept.The size of outer end minor axis 28 is enough big, so that be used as one handle when making bat 10.Preferably, the diameter of minor axis 28 is about 1 inch, is about the 2-3 inch.Minor axis 26 on the kob end is much smaller, and diameter is about 3/4 inch, is about 1/2 inch.Carve longitudinal fluting 30 on the handle portion 17 of reel 12.These grooves help resin to soak and flood one or more layers glass fibre cover along the handle portion of reel.Preferably, these grooves are symmetrically distributed on the periphery of handle portion, from from kob 1  inch along the bat length extending about 15 inches or more.The effective dimensions of groove 30 and shape can be any.4 0.06 inch * 0.06 inch the square groove that use is symmetrically distributed on the handle periphery can obtain gratifying effect.

Fig. 3 illustrates preform bat assembly 32.Continuous, unbroken one or more layers applying fabric cover 34 of these assembly 32 usefulness covers on the almost whole outer surface of reel 12 and forms.Preferably, continuous, unbroken layer glass fibrage cover of representing with

label

36 and 38 in Fig. 6 and 7 tightly is enclosed within on the reel 12.Though preferably use continuous two-layerly, continuous one deck is perhaps just enough, maybe can use three layers or more multi-layered, and this is decided by that the density of glass fiber and this braid or cover weave loose still tightly.

The diameter of cover 34 generally remains unchanged, its be woven into or form each thread orthogonal and with the longitudinal axis of reel 12 angle at 45 or+45 °/-45 °.Concerning the object of the invention, filametntary 0 ° of direction is parallel with the longitudinal axis of reel 12 or bat 10, and 90 ° of directions are axially around reel or bat in a plane vertical with longitudinal axis.Direction is the plane at filament place of+45 ° or-45 ° and the longitudinal axis angle at 45 of reel or bat, and+45 ° of planes are vertical with-45 ° of planes.

Fig. 8 illustrate filametntary preferred+45 °/-45 ° directions, wherein,

filament

40 and 42 is orthogonal, and become with the longitudinal axis of cover 34 respectively+45 °/-45.These

filaments

40 and 42 are represented with solid line in Fig. 3,4 and 5 for simplicity's sake.Its excellent body diameter is that the preferred form of glass fibre cover 34 of 2.50 inches bat is a braid, and the internal diameter of this braid is about 2.25 inches, and this size is slightly smaller than the maximum gauge of reel 12, and this maximum gauge preferably is about the 2.35-2.40 inch.The weight of one preferred braid and density are about 26.5 feet every pound and 9 ounces every square yard, and it is the A ﹠amp by Kentucky State Covington; (the A ﹠amp of P technology company; P Technology of Covington, Kentucky) produce and market.

Although the cover that is woven into glass fiber or bundle is with the preferred structure of the cover 34 that generates

layer

36 and 38 of the present invention, also can use within the scope of the present invention with weaving or knitted covers that glass fibre and/or other high strength fibre silks are made.This is weaved or knitted covers can have a vertical linear slit, also can not have vertical linear slit.Therefore, with regard to the object of the invention, term " cover " not only comprises preferred braiding cover, also comprise can be made into that one of glass fibre and/or other high strength fibres do not interrupt continuously, fitting that cover any weaves, knit goods and other fabrics.

As mentioned above, the internal diameter of preferred glass fibers cover 34 is slightly smaller than the external diameter of reel 12 rod-rod-bodies 19.Strut slightly when therefore, cover 34 is helped pull a cart on the rod-rod-body 19.Cover 34 and excellent body 19 so tightly be nested together can guarantee

glass fiber

40 and 42 on the rod-rod-body 19 of reel 12+45 °/-45 ° directions remain unchanged or increase slightly.Among Fig. 3 in the preform bat assembly 32 and Fig. 5 partial enlarged drawing in label 46 represent in this rod-rod-body 19 this+45 °/-45 ° directions.

On the other hand, cover tightly is not enclosed within on the reel 12 usually on its top 54 or along its handle portion 17.By rotating reel 12, tighten up on reel 12 on the top 54 of cover 34.Fig. 5 cover 34 54 places on the top are shown this tighten up.Therefore can see that each layer of cover of contraction covered the whole surface on the top 54 except 44 positions, bottom surface of the short supporting axle 28 that stretches out from reel 12 top axial.Available peculiar methods of the present invention covers cover top 54 and the tight bottom surface 44 of overlapping minor axis 28, but also available any other method covers the top of reel.

Simultaneously, tensioning braiding cover 34 makes cover at handle portion upper edge longitudinal tensile strain on the handle portion 17 of reel.This elongation make filament 40 in the handle portion and 42 direction shown in label 48 in Fig. 3 and 4 more approaching vertically.The angle of filament 40 and 42 in handle portion and between the longitudinal axis be significantly smaller than braid shown in Figure 8 normal+45 °/-45.Therefore, we find, direction is preferably in+45 °/-45 ° go up, its internal diameter equals or be slightly smaller than continuous, unbroken one or more layers glass fibre of wooden bat rod-rod-body diameter or the braiding cover of other high strength fibres is very suitable for making lamination bat of the present invention.Exactly, when this braiding cover is set on the reel, glass fiber being strutted of excellent body than major diameter, thus make its direction be equal to or slightly greater than+45 °/-45 °.Then, after layer 36 and 38 is set on the reel, stretched and when tightening up on the handle portion at reel, filament haled into direction be significantly smaller than+45 °/-45 °.The filament direction has increased filametntary longitudinal strength greatly towards this change of 0 ° of direction, thereby has improved the strengthening effect of bat handle glass fibre.In addition, the stretching of braiding cover and tighten up the filament that makes in the handle portion and lock mutually, thus improved filament intensity in the vertical greatly.Preferred orientations during filament generation interlocking in the bat handle is about from+20 °/-20 to+25 °/-25 °.

As a part of the present invention, we find, an available hollow bushing is set to each layer that continuously, do not interrupt of preferred glass fibers braiding cover on the whole surface of reel 12 and generates preform bat assembly 32 quickly and easily.This method is illustrated among Fig. 9,10 and 11, and this overlaps effective label 50 expressions.The length of cover is chosen to comprise two-layer at least, so that be applied to right two-layer at every turn.Then cover 34 being set to its internal diameter is a bit larger tham on the outer surface of sleeve pipe 50 of maximum gauge of reel.Can use the satisfactory any suitable hard plastic tube of internal diameter, but preferably use the transparent PVC plastic tube.Before or after cover 34 was set on the sleeve pipe 50, shown among Fig. 9 52, this near-end was tightened with belt and so on.Can insert reel 12 this moment in cover 34 and sleeve pipe.

After cover 34 was set on the outer surface of sleeve pipe 50, what the handle end 17 of reel 12 pushed cover 34 tightened end 52, thereby cover is pushed in the sleeve pipe 50.Along with being pushed into sleeve pipe, cover 34 is set on the bat from the outer surface of sleeve pipe 50 under the tension force effect.This longitudinal tension force that acts on the cover is tightened to cover on the handle portion 17 of reel, thereby it is required vertical to make that filametntary direction becomes.When reel 12 all inserts in the sleeve pipe 50, the short supporting axle 28 of excellent body end is rotated reel as handle.This rotation or reverse and force cover 34 on the outer end 54 of reel 12, to tighten up.Rotate reel, the annular bottom surface 44 that converges with the reel top that tightly wraps minor axis 28 up to cover, thus cover the remainder of reel end 54 fully.This moment, the ground floor 36 of cover 34 was enclosed within on the reel 12.

How many angles reel 12 rotates could cover reel end 54 is decided by cover up to the bottom surface 44 of minor axis 28 characteristic fully, comprises the tightness of density, braid etc.Use above-mentioned fiberglass braided cover, reel need only rotate about half-turn cover 34 just can wrap reel end 54.Because cover wraps on bottom surface 44, so reel can extract out from sleeve pipe and cover can not unclamp and take off, and the second layer 38 of extracting glass fibre cover 34 along with reel from sleeve pipe 50 out constantly is set on the reel 12.Therefore, this two-layer being close together can be set to continuous, unbroken two-

layer

36 and 38 of high strength cover 34 on the whole outer surface of reel 12 quickly and easily.In fact, the second layer 38 just oppositely is enclosed within on the whole ground floor 36.As long as repeat said method, can overlap several layers equally again, overlap one deck at every turn or overlap two-layer at every turn in couples.In addition, cover can constantly be set on sleeve pipe 50 outer surfaces from non-operative end.

When from sleeve pipe 50, extracting reel 12 out, cut off cover 34 at 26 some inches places of short supporting axle from this end of reel.Relative this end 41 of reel 12 tensionings cover sublayer 38 then, so as to tighten up cover on the handle portion 17 of reel as mentioned above and make layer 38 in bat handle 17

filament

40 and 42 direction change over required interlocking direction.Just can realize this tensioning as long as when catching layer 38 outer end 41 short supporting axle 28 is rotated reel as handle.In addition, press the bottom surface of kob 21 and make cover tightly overlap the kob end with pipe., can be set to a PVC plastic tubulature 39 on layer 38 and the minor axis 26, this end of braid is pushed the bottom surface of kob 21 to along with this pvc pipe and is tightened up for this reason.The turnover poststack is tightened (not shown) with belt on the end 41 of layer 38 then.In case of necessity, can screw pipe 39 and further tensioning skin 38 to kob 21 bottom surfaces.Thereby generate preform bat assembly.

Available suitable curable resin firmly is bonded in the

layer

36 and 38 of cover 34 and generates bat 34 on the whole outer surface of reel 12.As long as can firmly be adhered to each glass layer on the reel, and crack, fracture do not take place or brokenly falling at square stance, can use any curable resin.In addition, the outward appearance of strengthening bat owing to the present invention should be the same with the normal wood ball-making bar, therefore preferably uses transparent resin.Therefore, curable resin of the present invention should have between the transparency, crack resistance, impact resistance, each layer and the high adherence between each surface and can with the velocity vertical direction on the high elastic modulus of dissipation energy.

Preferred resin of the present invention is the thermosetting epoxy resin that solidifies automatically under near room temperature or room temperature.The solvent of epoxy preferably based on 2,2 '-(1, the 3-phenylene) two-2- azoles quinoline oxazoline.Also can use other difunctionalitys and polyfunctional epoxy resin, can add monofunctional diluent, also can not add monofunctional diluent.The transforming agent or the curing agent that can be used to generate the thermoset epoxy resin comprise multifunctional primary amine and secondary amine, lewis acid, lewis base, bibasic carboxylic acid and acid anhydride (dibasic carboxylic acids and anhydrides) etc.The preferred consolidation agent comprises diethylenetriamines, diethylenetriamine, m-xylene diamine, α-aminoethyl piperazine and so on alkylamine.Polyoxypropylene amine (polyoxypropyleneamines), amidoamines (amidoamines), polyamide and cyclic aliphatic polyamine (cycloaliphatic polyamines) also can be used as total transforming agent or mixture.This mixing ratio is haply by chemical dose proportioning (except Louis's bronsted lowry acids and bases bronsted lowry), and each epoxy radicals comprises the hydrogen (active aminehydrogen) of the amine of an activity.Except epoxy component and amine curing component, can contain and separate out when solidifying and form the 3rd component of discrete second phase.This second is an elastic pellet mutually, and diameter is preferably less than 1 micron, be clipped in and be bonded in continuous epoxy mutually in.This second improves crack resistance, impact resistance mutually, makes each layer premature disengagement not of this compound.This preferred resin material is by Applied Polymeric company (Applied Polymeric Inc.of Benicia, the California) produce and market of California Benicia.

In order to improve the bonding force of preferred epoxy on the bat reel, be preferably in each layer of glass fibre cover and be set to reel and go forward on the bat reel, to be coated with end agent.This end agent may penetrate into bridging agent or the interface that is used as in this wood between reel and the glass fibre.Preferred end agent component is hypotoxicity, low cost, working life is long, permeability is strong, Tg＞60 ℃ and low-viscosity epoxy resin emulsion.A kind of one pack system thermoplastic epoxy resin that molecular weight is about 30,000, have suitable cohesion and a penetrating solvent is effective especially.Also can obtain gratifying result by a kind of epoxy resin that two parts constitute, wherein part B contains the mixture of alkylamine, acyl alkylamine and surface active emulsifying agent, but owing to having two kinds of components and working life shortly to be not so good as top the sort of one-component epoxy resin.Other embodiment of end agent composition comprise the aqueous solution of resorcinol formaldehyde (resorcinol formaldehyde), urea-formaldehyde (urea formaldehyde) and the methylolated resorcinol of polyaziridine (polyethylenimine hydroxymethylatedresorcinol).This agent of preferred end is also by Applied Polymeric company produce and market.

Fig. 6 and 7 amplification profile illustrate between each layer of composite cover 14 and reel 12 surfaces firmly bonding, laminated together generation and strengthen bat 10.As shown in the figure, the

layer

36 and 38 of cover 34 has covered the whole surface except that bottom surface portions 58 bats 10 of the part 56 of outer end 22 and kob 18, and in these two parts,

minor axis

28 and 26 cuts after bat 10 is made.In addition, according to the present invention, kob need not to strengthen.Therefore, strengthening

layer

36 and 38 can cut off at kob 18 and handle portion 16 bottom meets 60.Minor axis 26 was cut into the bottom surface of kob 18 and flushes when in this case, bat was made.Therefore, according to the present invention, each strengthening layer of glass fibre cover covers the part 56 of bat outer end at least continuously from the meet of kob and handle 16.This continuous cover that do not interrupt that does not cover kob 18 covers more than 99% of club face.

That Figure 12,13 and 14 illustrates is bonding each layer of glass fibre cover, be laminated to a kind of known method on the reel.Preform bat assembly 32 places a mould 62, and this mould comprises female die 64 and upper mold section 66, respectively has half die cavity 68 to be used for holding preform bat assembly 32 in these two half modules.The component parts of this mould is known, when closing, suitable curable thermosetting or thermoplastic resin is injected die cavity 68 from inlet 70, thereby flood whole fiber

glass coating sublayer

36 and 38 with resin.Die cavity and preform bat assembly,

layer

36 and 38 received heat that comprise the resin dipping and the effect of pressure, the fusing of the temperature of heat and merge resin after firmly bonding each layer of cover, be laminated on the reel, also make the glass fiber of handle portion 16 keep beneficial direction shown in the label 48, the filament of rod-rod-body 14 keeps diagonal shown in the label 46.A kind of known injection molding technology is seen the U.S. Patent No. 5,301,940 of Seki, and just mould must make to hold the short supporting

axle

26 and 28 of end into.

Another part of the present invention is to use a kind of novel method to apply and solidify the epoxy resin of above-mentioned preferred epoxy and so on, so as firmly bonding each layer of glass fibre cover, be laminated on the reel.But, when using this preferred epoxy, before each layer of cover glass fibre cover, should be coated with above-mentioned preferred epoxy earlier on the reel 12 at the bottom of the end agent of agent and so on.Reel 12 preferably is heated to behind about 110  just primer coating.The air in the reel is not only drained in this heating, but also helps end agent to infiltrate in the wood.After the heating, in agent at the bottom of the reel immersion epoxy.After the drying, reel preferably immerses in the end agent once more, but does not heat specifically.Then can solidify and molded operation on this scribbles the reel of end agent, apply epoxy resin.

According to the present invention, found a kind of molding process of uniqueness, this technology can be more convenient than existing technology, quickly bonding each layer of glass fibre cover, be laminated on the reel, but cost reduces.The common plastics tube that this preferred molding process tightly is set to thermal contraction on the preform bat assembly is used as a mould that applies with cured epoxy resin.Below in conjunction with Figure 15,16 and 17 these molding process of explanation, in these accompanying drawings, the plastic tube-shape mould is represented with label 72.

Be enclosed within on the minor axis 28 of assembly 32 rod body ends in order to generate required tubular die 72, one sizeable hollow pipes 74.Pipe 74 comprises long tube portion 76 and the short tube portion 78 that is enclosed within on the minor axis 28.The diameter that is enclosed within the pipe portion 78 on the minor axis 28 is littler than pipe portion 76.Large diameter pipe portion 76 constitutes the spout of mould 72, and short tube portion 78 constitutes the looping pit 81 (seeing Figure 16) that enters the mould that encases preform bat assembly from spout 80.In general, pipe portion 76 can use the 1  inch cardboard hollow pipe that is about 20 inches.Short tube portion 78 can be bonded on the inner surface of paperboard tube portion 76 easily.Pipe 74 bottoms can be placed on the suitable support (not shown), and this support supports to the upright position to pipe 74.Then short supporting axle 28 is inserted in the short tube portion 78, thereby preform bat assembly 32 is supported on the pipe 74.

Be about a high collapsible tube 82 of 4 inches and be enclosed within outside preform bat assembly and the pipe 74 flattening width then.Pipe 82 can use the high collapsible tube of Thin-Wall PVC.With annular pharoid 84 and so on high collapsible tube 82 is shunk then and tightly overlap the skin of glass fibre cover.Preferably, pharoid 84 begins from pipe 82 bottoms to move automatically, begins to move up from preform bat assembly 32 outer ends then.As shown in figure 15, annular pharoid 84 is along the handle portion 17 that moves on to preform bat assembly 32 after this package assembly upwards moves past pipe 74, rod-rod-body 19.As shown in the figure, high contraction pipe 82 shrinks and tightly is enclosed within on pipe 74 and the preform bat assembly 32.Along with the contraction of pipe 82 on pipe 74 and preform bat assembly 32 discharged air in this pipe with a suitable hole.In case pharoid tightly entangles the kob end by whole this package assembly, pipe 82, just extract hollow pipe 74 out, stay preform bat assembly 32 and encase in the heat-shrinking plastics shell of a formation plastic tube-shape mould 72, excellent body end 54 places form an opening pipe elongated portion 85.

Because the handle portion 17 of bat is very big with the difference of the diameter of rod-rod-body 19, therefore, tubular die tightened up in the method on the handle portion of preform bat assembly require in this thermal contraction process stretched plastic mould tube in the heating of plastic mould tube, so that mould tube is tightened up on the handle portion of bat.Available any appropriate method in the handle portion 17 of bat in this thermal contraction process drawing die pipe simultaneously.But, a kind of simple method is, when annular pharoid 84 moves up its 3/4 stroke of pact, cancel support, so preform bat assembly 32 is unsettled with the remainder that the relative pipe 82 of thermal contraction part thereon of pipe 82 supports from the top with pipe 74 to pipe 74 and position preform bat assembly thereon.This that the acts on pipe 82 not gravity on the constriction makes that the thermal contraction of this part raying on one side heater 84 is stretched on one side, thereby tightly is set on the handle portion.

After from pipe elongated portion 85, extracting pipe 74 out, can be in the preform bat assembly 32 in the preferred epoxy 86 injected plastic tubular dies 72.Each component is placed in the room temperature environment.Each component of epoxy resin is mixed the pipe elongated portion 85 of back from spout 80 injection hollows.As use preferred epoxy, need only inject 7 ounces of mixed resins.Preferably about 1 square inch, the 14 inches elongated battens 88 of long Chinese ash are inserted in this pipe and be used as heat sink.Be used for the slowing down exothermic reaction of epoxy resin of this batten increases working time or " working life (the pot life) " of resin.Then the openend 80 of hollow pipe elongated portion 85 is inserted back clamping in the anchor clamps 90, improve the air pressure in this pipe elongated portion and the plastic tube-shape mould.This air pressure forces resin to soak each layer of glass fibre cover in the preform bat assembly and premature setting not in one rational period.Preferably, use the air pressure of about 10psi, the preform bat assembly 32 that makes epoxy resin flow through to be supported and the whole length of plastic tube-shape mould 72, thus resin begins to ooze from the opening 92 of mould at the handle end of assembly 32 after about 30-40 minute.As shown in figure 16, epoxy resin has soaked about 1/4 of preform bat assembly 32 on horizontal line shown in the label 94.This pressurization of plastic tube-shape mould is a kind of produced with combination method, is called " resin transfer moulding (ResinTransfer Molding) " in the prior art.

We find that the best room temperature that applies and solidify of epoxy resin is about 80-82 .Room temperature can increase the viscosity of resin as being lower than this temperature, causes and soaks overlong time.Room temperature can be unfavorable for the exothermic reaction of resin as being higher than this temperature, thus the bat that infringement is generated.

After preform bat assembly 32 soaks, can be inverted the tight below (seeing Figure 17) that the back is clamped in bat with anchor clamps 96 kob 18.Can make uncured resin and glass fibre be full of handle/kob interface better like this.Preferably, anchor clamps 96 are made and are heated to the above back of 200  and form one in the junction of the top of the kob 18 of bat and the bottom of handle portion 16 and forever encircle.If each layer of glass fibre cover effectively soaks into, just needn't carry out this clamping step in above-mentioned resin transfer moulding step.

Epoxy resin after solidifying in 1 -2 hour, and removing this tubular die 72 is the thermal contraction shell.Downcut the bat both ends of the surface that short supporting

axle

26 and 28 back finishings are exposed.Then handle portion is carried out sandblast, make it seem coarse.Although one or more layers applying fabric cover that above use is made by high strength glass fiber has illustrated some preferred embodiments, but the present invention also can use the fabric cover of being made by other high-tensile fibers, for example the fiber of Kevlar fabric (Kevlar), wave spectrum fiber (Spectra), carbon fiber, nylon fiber and so on.In addition, can weave, weave, be knitted into an applying cover to above-mentioned other high strength fibre silks with glass fiber within the scope of the present invention.Therefore, the invention is not restricted to only with cover fiberglass braided or that make.

In addition, reel 12 can use all timber.Usually use high-quality Ash to make high-quality wooden bat, the present invention can use this class wood.But, because the high strengthening effect of laminated glass fiber cover 14 of the present invention, but so reel 12 Chinese wax trees that also using character is lower.

At last, Figure 18 and 19 embodiment disclose

improved bat

100 and 200 respectively.A plurality of annular grooves 102 are arranged in Figure 18 bat 100.As shown in the figure, 15 grooves are arranged, each groove is wide about 3/16 inch, dark about 0.100 ± 0.010 inch.Leave wide approximately 3/16 inch stripes between every pair of groove of rod body.One longitudinal fluting 110 also is shown.Also has a corresponding groove 110 on the reverse side of bat 100.These two grooves 110 are wide about 1/32 inch, and the degree of depth is identical with groove 102.Identical with 4 grooves 30 of handle end, groove 110 is used for discharging air the groove 102 at resin when excellent body end flows to the kob end.Since braid excellent body end overlap pine, resin is in excellent body end flows faster, therefore compares with 4 grooves 30 of the handle end that braid overlaps tightly, resin flows is slower, excellent body end need only two grooves 110.

The same with the groove 102 of bat 100, Figure 19 bat 200 comprises a plurality of grooves 202.But groove 202 external edge (206) and internal edges (207) are curved.It is sinusoidal wave that the longitudinal profile of groove 202 is.(in Figure 18 bat, this section is square wave.) as drawing a straight line along excellent body surface, the top of the stripes between the every pair of groove 202 contacts this straight line.Shown in bat 200 do not have the longitudinal fluting 110 of bat 100.Because it is sinusoidal wave that the shape of groove is, therefore need not in addition with the air in the air flue discharge groove 202.In addition, the easier groove 202 that is full of of stir-in resin.But, in case of necessity, can use groove 110.

Bat

100 and 200 making are identical with above-mentioned bat 10.Be in the excellent body end more resins to be arranged, thereby help to prolong wooden service life in the bat batting district.CR-58 epoxy resin for bat 100 and 200,100 parts of Applied Polymeric companies mixes mutually with the HB-3 curing agent of 28 parts of Applied Polymeric companies.In the mould of a bat, use this mixture of 100g, have the 80-90g actual flow to cross bat approximately.

More than should regard example as the principle of the invention is shown.Those of ordinary skills can make all corrections and change.Therefore, the invention is not restricted to shown in, described concrete structure and working condition.All suitable correction and equivalent all drop in the scope of the invention.
