Description

KØLLEHODE TIL PUTTER FOR GOLFSPILL CLUB HEAD FOR PUTTER FOR GOLF

Oppfinnelsen vedrører et køllehode til en putter for golfspill, nærmere bestemt et putterhode som sett ovenfra er vingeformet og oppviser et stort treghetsmoment om en horisontal akse (z-akse) og om en vertikal akse (x-akse) gjennom putterens massemiddelpunkt i forhold til køllehodets masse. Dette fører til et redusert hastighets- og retningstap om golfballen blir truffet av putteren utenfor putterens "sweetspot" (det punktet på slagflaten som befinner seg i bevegel-seslinjen til køllehodets tyngdepunkt). Oppfinnelsen vedrører også stabiliseringshjelpemidler for golfkøllehodets vinger samt siktehjelpemidler integrert i golfkøllehodet. The invention relates to a club head for a putter for golf games, more specifically a putter head which, viewed from above, is wing-shaped and exhibits a large moment of inertia about a horizontal axis (z-axis) and about a vertical axis (x-axis) through the center of mass of the putter in relation to the club head a lot. This leads to a reduced loss of speed and direction if the golf ball is hit by the putter outside the putter's "sweetspot" (the point on the hitting surface which is in the line of motion of the center of gravity of the club head). The invention also relates to stabilization aids for the wings of the golf club head as well as aiming aids integrated in the golf club head.

Tradisjonelle puttere er designet som "hæl/tå-vektede" eller med såkalt "mallet"-form. Traditional putters are designed as "heel/toe-weighted" or with a so-called "template" shape.

Hæl/tå-vektede puttere har stort treghetsmoment om x-aksen og gir dermed lite hastighets- og retningstap ved horisontale feiltreff. Treghetsmomentet om z-aksen er derimot lavt, slik at hastighetstapet ved vertikale feiltreff blir stort. Heel/toe-weighted putters have a large moment of inertia about the x-axis and thus give little loss of speed and direction in the event of horizontal mishits. The moment of inertia about the z-axis, on the other hand, is low, so that the loss of speed in case of vertical mishits is large.

Mallet-puttere har relativt stort treghetsmoment om z-aksen, og hastighetstapet ved vertikale feiltreff er relativt lite. Treghetsmomentet om x-aksen er derimot relativt lite, slik at hastighets- og retningstapet ved horisontale feiltreff er stort. Mallet putters have a relatively large moment of inertia about the z-axis, and the loss of speed on vertical mishits is relatively small. The moment of inertia about the x-axis, on the other hand, is relatively small, so that the loss of speed and direction in the case of horizontal mishits is large.

US-patentsøknad 2003/013546 Al beskriver et vingeformet putterhode med tå- og haelvinger som rager med divergerende retning bakover fra slagflaten. Massemiddelpunktet er gitt en gunstig plassering ved at utsparinger i putterhodets kropp er fylt med et lettere materiale, fortrinnsvis elastomer som for eksempel polyuretan. US patent application 2003/013546 Al describes a wing-shaped putter head with toe and heel wings that project in a divergent direction backwards from the hitting surface. The center of mass is given a favorable location by recesses in the body of the putter head being filled with a lighter material, preferably elastomer such as polyurethane.

US-patent 6270422 Bl beskriver en putter med avtakbare hæl-og.tåvinger, hvor det på en toppflate på hver av vingene og på golfkøllehodet er anbrakt siktehjelpemidler i form av lin-jemarkeringer i flatene plassert i et horisontalplan vinkelrett på golfkøllehodets slagflate. US patent 6270422 Bl describes a putter with removable heel and toe wings, where on a top surface of each of the wings and on the golf club head aiming aids are placed in the form of line markings in the surfaces placed in a horizontal plane perpendicular to the hitting surface of the golf club head.

US-patent 5470070 beskriver et T-formet putterhode med sikte-linjer anbrakt i en øvre kølleflate og plassert i et horisontalplan vinkelrett på golfkøllehodets slagflate. US patent 5470070 describes a T-shaped putter head with sight lines placed in an upper club face and positioned in a horizontal plane perpendicular to the golf club head's hitting face.

WO-publikasjon 01/91860 Al beskriver et symmetrisk putterhode egnet både for høyre- og venstrehendte spillere, hvor sikte-linjer er anbrakt i golfkøllehodets øvre flate. WO publication 01/91860 Al describes a symmetrical putter head suitable for both right- and left-handed players, where aiming lines are placed in the upper surface of the golf club head.

US-patent 6273831 beskriver et golfkøllehode med en forsenk-ning og en innsats som er anbrakt i forsenkningen. Det beskrives polymermaterialsammensetninger for innsatsen med det formål å skaffe tilveie en kølle, særlig en putterkølle, med en myk slagflate for forbedret slagfølelse og slagelastisi-tet. US patent 6273831 describes a golf club head with a recess and an insert which is placed in the recess. Polymer material compositions for the insert are described with the aim of providing a club, in particular a putter club, with a soft impact surface for improved impact feel and impact elasticity.

US-patent 5830078 beskriver et putterkøllehode som omfatter et hæl- og et tåparti som strekker seg bakover fra køllens slagflate. Putterkøllehodet omfatter videre et bakre parti som danner en utkraging som strekker seg bakover fra køllens fremre parti samt et bakre element som støttes av utkragingen og er anbrakt omtrent like langt fra hæl- og tåpartiene. Utkragingen er formet som en plate med en øvre flate som sam-menfaller med et stagparti som strekker seg mellom det bakre elementet og tå- og hælpartiene, og hvor den bakre platekan-ten er i det vesentlige bueformet. US patent 5830078 describes a putter club head that includes a heel and a toe portion that extends rearward from the club's hitting face. The putter club head further comprises a rear part which forms a cantilever which extends backwards from the front part of the club and a rear element which is supported by the cantilever and is located approximately equidistant from the heel and toe parts. The cantilever is shaped like a plate with an upper surface which coincides with a strut part which extends between the rear element and the toe and heel parts, and where the rear plate edge is substantially arc-shaped.

Det er av stor betydning for en putterkølles slagegenskaper at køllehodets stilling i slagøyeblikket i minst mulig grad påvirkes av sammenstøtet med ballen. I det ideelle slaget treffer putteren ballen i sweetspot. Effektiv masse i beveg-else i slaget er ikke bare køllehodet, men også deler av skaftet. Sweetspot (rotasjonssenteret) for en kølle med skaft ligger høyere enn sweetspot (tyngdepunktet) for golfkølleho-det alene. Det fleste puttere har i praksis sweetspot høyere enn slagflatens sentrum. De fleste spillere treffer ballen med slagflatens sentrum. Det er dermed gunstig å flytte køl-lehodemasse nedover slik at køllas virkelige sweetspot senkes ned mot slagflatens senter. It is of great importance for a putter club's impact characteristics that the position of the club head at the moment of impact is affected to the least extent possible by the impact with the ball. In the ideal stroke, the putter hits the ball in the sweetspot. Effective mass in motion in the stroke is not only the club head, but also parts of the shaft. The sweetspot (center of rotation) of a club with a shaft is higher than the sweetspot (center of gravity) of the golf club head alone. In practice, most putters have a sweet spot higher than the center of the hitting surface. Most players hit the ball with the center of the face. It is therefore beneficial to move the club head mass downwards so that the club's real sweet spot is lowered towards the center of the hitting surface.

En viktig faktor for gode prestasjoner i putting er dessuten å kunne sikte putteren i riktig vinkel mot målet. For å gjøre siktingen lettere finnes det forskjellige utforminger hvor streker eller sirkler på golfkøllehodet eller formen på nedre del av skaftet danner virtuell(e) siktelinje(r) som inntar en retning vinkelrett på putterens slagflate sett ovenfra. An important factor for good putting performance is also being able to aim the putter at the right angle towards the target. To make aiming easier, there are different designs where lines or circles on the golf club head or the shape of the lower part of the shaft form virtual sight line(s) that take a direction perpendicular to the putter's hitting surface seen from above.

Oppfinnelsen har til formål å avhjelpe ulempene ved kjent teknikk. The purpose of the invention is to remedy the disadvantages of known technology.

Formålet oppnås ved trekk som er angitt i nedenstående be-skrivelse og i etterfølgende patentkrav. The purpose is achieved by features which are indicated in the description below and in subsequent patent claims.

Et køllehode for en putter har ifølge kjent teknikk en vinge-form, idet en tåvinge strekker seg bakover fra et tåparti på køllehodet og i retning bort fra en slagflate på et fremre parti av køllehodet, samt at en hælvinge strekker seg bakover fra et haelparti på køllehodet og i retning bort fra kølleho-dets slagflate. Vingenes ytre sidekanter kan ha divergerende retning sett fra køllehodets slagflate. A club head for a putter has, according to known technology, a wing shape, in that a toe wing extends backwards from a toe part of the club head and in the direction away from a striking surface on a front part of the club head, and that a heel wing extends backwards from a heel part of the club head and in a direction away from the club head's impact surface. The outer side edges of the wings can have a divergent direction seen from the club head's impact surface.

Et golfkøllehode for en putterkølle ifølge oppfinnelsen er forsynt med en tåvinge som rager utover fra et tåparti, en haelvinge som rager utover fra et hælparti, og hvor vingene hver for seg er forsynt med en utovervendende sideflate som divergerer i forhold til hverandre i retning bort fra en slagflate, kjennetegnet ved at massen pr. lengdeenhet av et bakre endeparti av hver vinge er større enn massen pr. lengdeenhet for et midtparti av vingene; og at minst ett avstivingsmiddel forbinder og avstiver vingene. A golf club head for a putter club according to the invention is provided with a toe wing that projects outwards from a toe section, a heel wing that projects outwards from a heel section, and where the wings are each provided with an outward facing side surface that diverges in relation to each other in a direction away from an impact surface, characterized by the mass per length unit of a rear end part of each wing is greater than the mass per unit of length for a central portion of the wings; and that at least one stiffener connects and stiffens the wings.

Minst ett av det minst ene avstivingsmiddelet er fordelaktig fastgjort til et køllemidtparti, anordnet mellom golf-køllehodets tåparti og hælparti. At least one of the at least one stiffening means is advantageously attached to a club center portion, arranged between the toe portion and the heel portion of the golf club head.

Det minst ene avstivingsmiddelet kan være tildannet som en plate som utfyller mellomrommet mellom vingenes nedre partier. The at least one stiffener can be formed as a plate which fills the space between the lower parts of the wings.

Alternativt kan det minst ene avstivingsmiddelet være tildannet som tverrstag som forbinder vingenes bakre endepartier og avstiver vingene, og via et støttestag er stivt forbundet med køllemidtpartiet. Alternatively, the at least one stiffening means can be formed as a cross brace which connects the rear end portions of the wings and stiffens the wings, and is rigidly connected to the center section of the club via a support brace.

Hver av vingene kan omfatte et innovervendende, rettlinjet sidekantparti som ligger i hovedsak parallelt med hverandre og som i et horisontalplan står i hovedsak vinkelrett på slagflaten. Det rettlinjede sidekantpartiet kan ha en utstrekning på minst 10 mm. Each of the wings can comprise an inward-facing, rectilinear side edge portion which lies essentially parallel to each other and which, in a horizontal plane, is essentially perpendicular to the impact surface. The rectilinear side edge portion can have an extent of at least 10 mm.

Tåvingen og hælvingen kan hver for seg være forsynt med en siktelinjemarkering som ligger parallelt med det innovervendende, rettlinjede sidekantpartiet. The toe wing and the heel wing can each be provided with a line of sight marking that lies parallel to the inward-facing, rectilinear side edge portion.

Vingenes nedre, innvendige kantflater kan være parallelle og stå vinkelrett på slagflaten sett i et horisontalplan og ved dette danne et siktehjelpemiddel. Parallelt med vingenes nedre, innvendige kantflater kan vingene fordelaktig være forsynt med ytterligere et siktehjelpemiddel i form av siktelinjemarkeringer. The lower, inner edge surfaces of the wings can be parallel and stand perpendicular to the impact surface seen in a horizontal plane and thereby form an aiming aid. Parallel to the wings' lower, inner edge surfaces, the wings can advantageously be provided with a further aiming aid in the form of sight line markings.

Alternativt eller som tillegg til de ovenfor nevnte siktehjelpemidler kan hver av vingene være forsynt med et siktehjelpemiddel i form av én eller flere siktelinjemarkeringer på en vingetoppflate, hvor siktelinjemarkeringene i et horisontalplan ligger vinkelrett på slagflaten. Alternatively or in addition to the above-mentioned aiming aids, each of the wings can be provided with an aiming aid in the form of one or more sight line markings on a wing top surface, where the sight line markings in a horizontal plane are perpendicular to the impact surface.

Golfkøllehodet kan alternativt være forsynt med siktehjelpemidler anbrakt på eller integrert i de avstivende forbindel-sene mellom vingene og/eller mellom vingene og golfkølleho-dets fremre parti. The golf club head can alternatively be provided with aiming aids placed on or integrated into the stiffening connections between the wings and/or between the wings and the front part of the golf club head.

Golfkøllehodets massemiddelpunkt er plassert lavere enn slagflatens senter. Dette er oppnådd ved at vingene i et fremre og et midtre parti fordelaktig har et tilnærmet L-formet tverrsnitt. Også andre tverrsnittsformer som gir en overvekt av masse i vingenes nedre parti, kan benyttes. The center of mass of the golf club head is located lower than the center of the hitting surface. This is achieved by the wings in a front and a middle part advantageously having an approximately L-shaped cross-section. Other cross-sectional shapes that give a preponderance of mass in the lower part of the wings can also be used.

Mer spesifikt kan tåpartiet og hælpartiet ha et L-formet tverrsnitt hvor et nedre parti rager i det vesentlige horisontalt i retning bort fra slagflaten. More specifically, the toe part and the heel part can have an L-shaped cross-section where a lower part projects substantially horizontally in a direction away from the striking surface.

Mer spesifikt kan det midtre partiet av hver av vingene ha et L-formet tverrsnitt hvor et bunnparti i det vesentlige rager horisontalt i retning bort fra den ytre sideflaten. More specifically, the middle part of each of the wings can have an L-shaped cross-section where a bottom part substantially projects horizontally in a direction away from the outer side surface.

Alternativt kan massemiddelpunktets plassering senkes ved at det anvendes et lett materiale, for eksempel aluminium, i golfkøllehodets øvre partier kombinert med et tungt materiale, for eksempel tungsten, i golfkøllehodets nedre partier. Alternatively, the position of the center of mass can be lowered by using a light material, for example aluminium, in the upper parts of the golf club head combined with a heavy material, for example tungsten, in the lower parts of the golf club head.

Mot vingenes bakre endeparti øker den vertikale veggens tyk-kelse samtidig som vingens bredde øker. Derved anbringes det også mye masse i vingenes bakkant slik at golfkøllehodets treghetsmoment om en vertikal akse gjennom sweetspot blir stort. Towards the rear end of the wings, the thickness of the vertical wall increases at the same time as the width of the wing increases. Thereby, a lot of mass is also placed at the trailing edge of the wings so that the golf club head's moment of inertia about a vertical axis through the sweetspot becomes large.

Golfkøllehodets treghetsmoment om den vertikale aksen kan også økes ved at det anvendes et lett materiale, for eksempel aluminium, i golfkøllehodets midtre partier kombinert med et tungt materiale, for eksempel tungsten, i golfkøllehodets ytre partier. Det er også gunstig at golfkøllehodet oppviser et stort treghetsmoment om en horisontal tverrakse gjennom sweetspot. Dette oppnås ved å anvende et tungt materiale i golfkøllehodets bakre og ytre partier, dvs. ytterst i vingene, mens det benyttes et lett materiale i golfkøllehodets midtre partier og fremre partier. The golf club head's moment of inertia about the vertical axis can also be increased by using a light material, for example aluminium, in the middle parts of the golf club head combined with a heavy material, for example tungsten, in the outer parts of the golf club head. It is also beneficial that the golf club head exhibits a large moment of inertia about a horizontal transverse axis through the sweetspot. This is achieved by using a heavy material in the rear and outer parts of the golf club head, i.e. at the very end of the wings, while a light material is used in the middle parts and front parts of the golf club head.

Mer spesifikt kan golfkøllehodets bakre partier i det vesentlige utgjøres av et materiale med egenvekt større enn 3,5 kg/dm3, og golfkøllehodets fremre partier kan i det' vesentlige utgjøres av et materiale med egenvekt mindre enn 3,5 kg/dm<3>. Golfkøllehodets nedre partier kan dessuten i det vesentlige utgjøres av et materiale med egenvekt større enn 3,5 kg/dm<3>, og golfkøllehodets øvre partier kan i det vesentlige utgjøres av et materiale med egenvekt mindre enn 3,5 kg/dm<3>. Golfkøllehodets bakre og ytre partier kan ytterligere i det vesentlige utgjøres av et materiale med egenvekt større enn 3,5 kg/dm3, og golfkøllehodets midtre partier kan i det vesentlige utgjøres av et materiale med egenvekt mindre enn 3,5 kg/dm<3>. More specifically, the rear parts of the golf club head can essentially consist of a material with a specific weight greater than 3.5 kg/dm3, and the front parts of the golf club head can essentially consist of a material with a specific weight less than 3.5 kg/dm<3> . The lower parts of the golf club head can also essentially consist of a material with a specific weight greater than 3.5 kg/dm<3>, and the upper parts of the golf club head can essentially consist of a material with a specific weight of less than 3.5 kg/dm<3 >. The rear and outer parts of the golf club head can further essentially consist of a material with a specific weight greater than 3.5 kg/dm3, and the middle parts of the golf club head can essentially consist of a material with a specific weight of less than 3.5 kg/dm<3> .

Det fremre partiet av golfkøllehodet omfatter slagflaten, tåpartiet, hælpartiet samt et skaftfesteparti. The front part of the golf club head comprises the hitting surface, the toe part, the heel part and a shaft attachment part.

I skaftfestepartiet har det fremre køllepartiet fordelaktig et L-formet tverrsnitt med det formål å anbringe en overvekt av masse i golfkøllehodets nedre parti. Alternativt har skaftfestepartiet et tverrsnitt med tilnærmet liggende U-form, hvor en øvre og en nedre sideflate er utformet for å gi en stabil innfesting til et skaft uten at det anbringes stor køllemasse i dette området. Det U-formede skaftfestepartiet går gradvis over i tverrsnitt med tilnærmet L-form eller an-nen tverrsnittsform som gir en overvekt av masse i golfkølle-hodets nedre parti. In the shaft attachment part, the front club part advantageously has an L-shaped cross-section with the purpose of placing a preponderance of mass in the lower part of the golf club head. Alternatively, the shaft attachment part has a cross-section with an approximately horizontal U-shape, where an upper and a lower side surface are designed to provide a stable attachment to a shaft without large club mass being placed in this area. The U-shaped shaft attachment part gradually transitions into a cross-section with an approximately L-shape or another cross-sectional shape which gives a preponderance of mass in the lower part of the golf club head.

I overgangen mellom tåpartiet og tåvingen, respektive hælpartiet og hælvingen, er tykkelsen av den vertikale veggen formålstjenlig øket for å skaffe tilveie tilstrekkelig stabili-tet på vingene. In the transition between the toe section and the toe wing, respectively the heel section and the heel wing, the thickness of the vertical wall is expediently increased to provide sufficient stability for the wings.

Golfkøllehodets fremre partis øvre sideflate er formålstjenlig forsynt med ytterligere et siktehjelpemiddel i form av en siktelinjemarkering som ligger parallelt med slagflaten. The upper side surface of the front part of the golf club head is expediently provided with a further aiming aid in the form of a sight line marking which lies parallel to the hitting surface.

Skaftfestepartiets øvre sideflate er på lignende vis formålstjenlig forsynt med ett eller flere siktehjelpemiddel i form av siktelinjemarkering(er) som ligger vinkelrett på slagflaten. Siktelinjemarkeringen(e) kan fordelaktig forlenges i retning bort fra slagflaten ved at skaftfestepartiet omfatter en eller flere utragende siktepinner. En av skaftfestepartiets siktelinjemarkeringer er fordelaktig sammenfallende med et vertikalplan som går gjennom golfkøllehodets "sweetspot". The shaft attachment part's upper side surface is similarly expediently provided with one or more sighting aids in the form of sight line marking(s) which lie perpendicular to the striking surface. The line of sight marking(s) can advantageously be extended in a direction away from the hitting surface by the shaft attachment part comprising one or more projecting sight pins. One of the shaft attachment portion's line of sight markings advantageously coincides with a vertical plane that passes through the golf club head's "sweet spot".

Siktelinjemarkeringene ut over de som utgjøres av golfkølle-hodets geometriske form (sidekanter, siktepinne og lignende) er dannet ved for eksempel utsparinger, forsenkninger, for-høyninger, fargemarkeringer eller lignende. The line of sight markings in addition to those formed by the geometric shape of the golf club head (side edges, sight pin and the like) are formed by, for example, recesses, recesses, front elevations, color markings or the like.

Hver vinge 31, 31' omfatter en vertikal sidevegg 33 og et i det vesentlige horisontalt bunnparti 35 som sammen danner et tilnærmet L-formet tverrsnitt. Den vertikale sideveggen 33 er forsynt med en ytre sideflate 37. Bunnpartiet 35 er forsynt med en innvendig sidekant 39 og en øvre bunnflate 41. Den øvre bunnflaten 41 er forsynt med et forsenket siktespor 43 som ligger parallelt med og som strekker seg i tilnærmet hele lengden av det rette partiet av sidekanten 39. Det rettlinjede sidekantpartiet 39 er fordelaktig minst 10 mm langt. I et bakre endeparti 45 går vingenes 31, 31' tverrsnitt gradvis Each wing 31, 31' comprises a vertical side wall 33 and an essentially horizontal bottom part 35 which together form an approximately L-shaped cross-section. The vertical side wall 33 is provided with an outer side surface 37. The bottom part 35 is provided with an inner side edge 39 and an upper bottom surface 41. The upper bottom surface 41 is provided with a recessed sighting groove 43 which lies parallel to and which extends for almost the entire length of the straight part of the side edge 39.

over fra L-form til en rektangelform. over from L-shape to a rectangle shape.

Hver vinge 31, 31' omfatter også en vingetoppflate 42 som hver er forsynt med en siktelinjemarkering 44. Siktelinjemarkeringene 44 ligger i et horisontalplan, er innbyrdes parallelle og er parallelle med respektive vinges 31, 31' rette sidekant 39. Each wing 31, 31' also includes a wing top surface 42, each of which is provided with a line of sight marking 44. The line of sight markings 44 lie in a horizontal plane, are parallel to each other and are parallel to the straight side edge 39 of the respective wing 31, 31'.

En fremre toppflate 47 er forsynt med et forsenket siktespor 49 som ligger parallelt med slagflaten 27. A front top surface 47 is provided with a recessed aiming groove 49 which lies parallel to the impact surface 27.

Festepartiene 29, 29' er formålstjenlig forsynt med et hull 51, 51' for innføring av skaftet (ikke vist). The fastening parts 29, 29' are expediently provided with a hole 51, 51' for inserting the shaft (not shown).

Det øvre festepartiet 29 er forsynt med et forsenket siktespor 53 som i et horisontalplan står vinkelrett på slagflaten 27 og er anbrakt i et vertikalplan som står vinkelrett på slagflaten 27 og går gjennom golfkøllehodets "sweetspot". Siktesporet 53 er gjennombrutt av skafthullet 51. Fig. 9 viser en alternativ utførelse av golfkøllehodet 21, hvor siktesporet 53 er forlenget bakover langs en siktepinne 54. Fig. 10 viser en ytterligere utførelse av golfkøllehodet 21, hvor en mellomplate 65 utfyller mellomrommet mellom vingenes 31, 31' bunnpartier 35. En siktelinjemarkering 67 i mellom-platens 65 øvre flate 66 står vinkelrett på slagflaten 27. Fig. 11 og 12 viser en ytterligere utførelse av golfkølleho-det 21, hvor vingene 31, 31' er forbundet med hverandre ved hjelp av tverrstag 71, 71', idet tverrstagene 71, 71' rager ut fra vingenes 31, 31' bunnparti 35. Tverrstagene 71, 71' er forbundet med et støttestag 73 til et midtparti 75. Støtte-staget 73 er forsynt med rettlinjede, parallelle sidekantpar-tier 77 som står vinkelrett på slagflaten 27. En toppflate 78 er forsynt med en siktelinjemarkering 79. The upper attachment part 29 is provided with a recessed aiming groove 53 which in a horizontal plane is perpendicular to the hitting surface 27 and is located in a vertical plane which is perpendicular to the hitting surface 27 and passes through the golf club head's "sweetspot". The aiming track 53 is pierced by the shaft hole 51. Fig. 9 shows an alternative design of the golf club head 21, where the aiming track 53 is extended backwards along an aiming pin 54. Fig. 10 shows a further design of the golf club head 21, where an intermediate plate 65 fills the space between the wings 31 . of transverse struts 71, 71', the transverse struts 71, 71' projecting from the bottom part 35 of the wings 31, 31'. The transverse struts 71, 71' are connected by a support strut 73 to a central part 75. The support strut 73 is provided with rectilinear, parallel side edge parts 77 which are perpendicular to the impact surface 27. A top surface 78 is provided with a line of sight marking 79.

Tå- og hælpartiene 23, 25 har hver for seg et tilnærmet L-formet tverrsnitt, hvor et nedre frontparti 55 rager i det vesentlige horisontalt bakover i retning bort fra slagflaten 27. Det nedre frontpartiet 55 har en jevn overgang til det nedre festepartiet 29' for skaftet, alternativt til golfkøl-lehodets midtparti 75, samt vingenes 31, 31' bunnpartier 35. The toe and heel parts 23, 25 each have an approximately L-shaped cross-section, where a lower front part 55 projects substantially horizontally backwards in the direction away from the impact surface 27. The lower front part 55 has a smooth transition to the lower fastening part 29' for the shaft, alternatively to the middle part 75 of the golf club head, as well as the bottom parts 35 of the wings 31, 31'.

Ved hjelp av de utragende vingenes 31, 31' massekonsentrasjon i sine bakre endepartier 45 oppviser golfkøllehodet 21 ifølge oppfinnelsen et stort treghetsmoment. By means of the mass concentration of the projecting wings 31, 31' in their rear end portions 45, the golf club head 21 according to the invention exhibits a large moment of inertia.

Mellomplaten 65, alternativt tverrstagene 71, 71', forbinder vingene 31, 31' med hverandre og avstiver vingene 31, 31'. Dermed øker golfkøllehodets egensvingningsfrekvens, og dette gir en mindre hørbar lyd forårsaket av golfkøllehodets 21 treff mot ballen i slagøyeblikket. Tverrstagene 71, 71' øker samtidig massekonsentrasjonen i golfkøllehodets 21 bakre parti. The intermediate plate 65, alternatively the transverse struts 71, 71', connects the wings 31, 31' to each other and stiffens the wings 31, 31'. This increases the natural oscillation frequency of the golf club head, and this produces a less audible sound caused by the golf club head's 21 hits against the ball at the moment of impact. The transverse struts 71, 71' simultaneously increase the mass concentration in the rear part of the golf club head 21.

Støttestaget 73 øker vingenes 31, 31' stivhet ytterligere. The support strut 73 further increases the stiffness of the wings 31, 31'.

Ved at tå- og hælpartiene 23, 25 samt vingene 31, 31' har et i det vesentlige L-formet tverrsnitt og ved at tverrstagene 71, 71' rager ut fra vingenes 31, 31' bunnparti 35, er det oppnådd at golfkøllehodets 21 massemiddelpunkt er plassert lavere enn slagflatens 27 senter. By the fact that the toe and heel parts 23, 25 as well as the wings 31, 31' have an essentially L-shaped cross-section and by the fact that the transverse struts 71, 71' protrude from the bottom part 35 of the wings 31, 31', it has been achieved that the center of mass of the golf club head 21 is placed lower than the center of the impact surface 27.

Vingenes 31, 31' innvendige sidekant 39 sammen med sikte-sporene 43, 44, 49, 53 og 57, eventuelt støttestagets 73 sidekaritpartier 78 sammen med siktesporet 79 virker som sik-temidler for å øke slagpresisjonen. The inner side edge 39 of the wings 31, 31' together with the sighting grooves 43, 44, 49, 53 and 57, possibly the support strut 73's side carite parts 78 together with the sighting groove 79 act as aiming means to increase the hitting precision.
