TITLE OF THE INVENTION: An arrangement for sound damping
TECHNICAL FIELD
The present invention relates in general to an arrangement for sound damp- ing, and more particularly to an arrangement which is adapted to damp the sound generated from an oscillatory movement of a line into contact with and away from a pole-shaped device.
Such pole-shaped devices may be employed in many different contexts, but in the following description it will be exemplified in the form of a flagpole.
However, it will be obvious to the skilled in the art that the principles of the present invention may advantageously also be applied to masts on board sailing ships and vessels, in particular when the sails are lowered.
While the present invention may be considered as having a particular application to vertically oriented poles, it will be obvious to the skilled in the art that the principles of the present invention may also be applicable to obliquely oriented poles.
The principles of the present invention are further based on a situation that the line is to be adapted freely and to be able to extend a distances between an upper or uppermost region of the pole and a lower or lowermost region of the pole and be tightened between fixing points provided, and while utilising a fixing device provided for the lower section of the line and fixable to the lower section of the line while cooperating with the lower region of the pole, the fixing device being in the form of a cleat.
The tightening of a line along a vertical staff or pole has proved to give rise to monotonous "slapping" sounds because of the billowing movement of the halliard caused by air and/or wind turbulences around the halliard and/or the flagpole and it has proved that this slapping sound is to some degree amplified in hollow flag staffs or hollow aluminium masts on board ship, and such monotonous sound is perceived as disturbing or irritating by those needing a more restful and a quieter environment.
It is per se previously known in the art to attempt to obviate this inconvenience by securing to the pole a readily mountable and dismountable means a- dapted as an arm.
Such a means is based on the principle that the arm-adapted means is to be secured an adapted at a slight distance along the pole above said fixing device and be cooperated with the pole where such means, within its region close to the pole, displays a clamping arrangement which may be coordinated with the pole and, within a region distal from the pole, to display a groove- like recess, where said recess is adapted for a deviating cooperation with an interjacent section of the halliard located slightly above said lower section in order to pass or lead a distance of the halliard from the upper region of the pole and to said lower fixing device at a distance from the pole in order to be able to permit an oscillating movement caused by wind turbulence but free of contact with the pole.
Arrangements of the associated type may naturally be put into use during periods of time when a flag is raised or alternatively a sail is set during which periods of time the halliards or alternatively the halliard is extremely taut, but is likely to have a particular application during such periods of time when no flag is hoisted or alternatively when no sails are set on the mast and during which periods of time the halliards or halliard are not taut and set for taking up extreme stresses.
BACKGROUND OF THE INVENTION
Methods, arrangements and constructions relating to the above-disclosed technical field and with a function and of a nature which satisfy set require- merits are previously known in a plurality of different embodiments.
As a first example of the state of the art and the technical art to which the present invention relates, mention might be made of that which is shown and described in Patent Specification US-A-1 760337.
This specification shows and describes an arrangement for initially being able to tighten a flag with the aid of leads running up and down the flagpole and in order thereafter to be able to tighten the lead.
To this end, use is made of a flagpole with a pulley at the uppermost region of the flagpole and with retainer means in the lower region of the flagpole and with two leads running up and down and thereby passed over the pulley and secured to fixing means.
In this publication, there is disclosed the use of an arm-like arrangement which, unlike in the present invention however, is rotatably coordinated with the lower region of the flagpole and with guide means for cooperation with in any event one of the leads of the halliard or a selected lead along the flagpole and where the arm is disposed to be rotated from a vertical position to a more horizontal position in order by such means to increase the tension in the lead and increase the relevant distance between one or both of the parallel leads and the flagpole.
The arrangement here utilises a sweep (18) oriented around the flagpole (11) with utilised discrete clamping means (19, 20, 22) oriented in an extension of the arms (24) and in a connection mode to an outer pulley (30).
As a second example of the state of the art, reference is made to the contents of Patent Specification US-A-5 113 776, where an arrangement is shown and described for drawing one or more of the leads (12) a distance away from the flagpole (14), so that the leads will be able to be held at a greater distance from the flagpole than is normal without the utilisation of such an arrangement.
To this end, this publication discloses that a small base plate (30) is to be able to be secured, by means of bolts, to the flagpole (14) and support a pi- votal (30) arm (16), whose outer portion displays two grooves (26) one for each of the leads or selected halliard sections along the flagpole and partly for increasing the tensioning in the leads for maintaining the leads at a distance from the flagpole and also at a distance from one another.
Features common to the prior art as shown here are that these arrangements require an arm, which is rotatably secured in its one end and which via a horizontally oriented pivot axis is rotatably disposed between a horizontal position and an upwardly directed vertical position, or vice versa.
BRIEF SUMMARY OF THE PRESENT INVENTION TECHNICAL PROBLEM
Taking into account the circumstance that the technical considerations which a person skilled in the art must do in order to be able to offer a solution to one or more established technical problems is, on the one hand, initially a ne- cessary insight into the measures and/or the sequence of measures to be implemented and, on the other hand, a necessary selection of the means which are required, the following technical problems are likely, in view hereof, to be relevant in the evolution or development of the subject matter of the present invention.
Taking into account the state of the art, as described above, it should therefore probably be seen as a technical problem to be able to realise the impor-
tance of, the advantages associated with and/or the technical measures and considerations which will be required in order, in an arrangement structured to damp sound from the oscillating movement of a halliard or a lead to contact with and from a pole-shaped device, such as a flagpole, a sail mast or the like, where said halliard or leads, in the form of coordinated halliard sections, are adapted freely to be able to extend between the upper region of the pole and the lower region of the pole, and with a lower line section allocated to the lower region of said lead and fixable to a fixing device coordinated with the lower region of the pole, in the form of a cleat, there being secured, at an adapted distance along the pole above said fixing device, an arm-adapted means which is readily removably disposed in relation to the pole, where said means, within its portion proximal the pole displays a clamping arrangement coordinated with the pole and within its distal portion in relation to the pole displays a groove-shaped open recess, where said recess is adapted for a deviating cooperation with in any event one lead section located over said lower lead section in order to move or lead said section from the upper region of the pole and to said fixing device, at a distance from the pole in order to be able to offer an oscillating movement free of contact with the pole, to create a fixed arm-adapted means, which is easy to manufacture in few individual parts which are easy to assemble with one another which are simply design- ned for a simple and fixed cooperation with the lower portion of the pole, which is cost effective and economically manufactured and will be simple to pack, ready for shipping as a result of its flat configuration.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order to cause said arm-adapted means to be produced from a plastic material and as such be formed so as to follow a planar manifest configuration with an acute angle falling within specifically dis- closed angle values.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order to cause an arm-adapted means and its portion proximal the pole to display a semicircular, or in any event substanti- ally semicircular recess, with a curvature which approximates the radius of the pole adjacent said arm-adapted means and that to said pole proximal portion there are, via discrete fixing means, fixedly but readily removably disposed a semicircular, in any event substantially semicircular, stirrup arrangement.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order to cause said groove-shaped recess to be formed as a "clinch" arrangement.

There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order to cause an additional cleat to be fixable to and supported by said narrow portion.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order to cause said cleat to be orientable to
and, as a separate unit, to be easily removably fixable to the upper surface of the triangular configuration.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order to cause said cleat to be orientable to and, as a separate unit, to be readily removably fixable to the lower surface of the triangular configuration.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order to cause said discrete fixing device, intended to be able to interconnect the two parts which are included in the arm- adapted means, to be adapted for cooperation with a threaded hole in the ou- ter shanks of the previously disclosed portion proximal to the pole.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order, as a second alternative construction, to cause said arm-adapted means to consist of a narrow arm with a small and very acute angle given to the tip of the triangular configuration and to cause a concave curved base given to the triangular configuration to be associated with an extent less than half of the semicircular recess.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order to cause a "free" space to be disposed outside the semicircular recess and which space is to be adapted in order, in taut line leads, to allow a free passage of an adjacent line section past the arm-adapted means or alternatively to permit a minor deviation of the line leads about said means.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order to cause in any event the arm portion of the arm-adapted means to display a thin central portion and coordinated ed- ge portions raising flexural resistance in the form of wall portions.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order to cause the tip of the triangular confi- guration to be given an angle selected between 0 and 30°.
SOLUTION
In such instance, the present invention takes as its point of departure or origin the prior art as disclosed by way of introduction relating to an arrange- ment intended for sound damping from a pivotal and/or oscillating movement of a line or halliard to contact with and from a pole-shaped device, such as a flagpole, a sail mast or the like, where said line or halliard is adapted, as a line lead or alternatively line leads and line sections related thereto freely to be able to extend between the upper portion of the pole and the lower portion of the pole and with a lower line section allocated to said line or halliard or the lower portion of a line lead fixable with a fixing device coordinated with the lower portion of the pole, such as a cleat, there being, at an adapted distance along the pole above said fixing device, secured but readily removably coordinated with the pole an arm-adapted means where said means within its portion proximal the pole is to display a clamping arrangement which may be coordinated with the pole and, within its portion distal from the pole to display a groove-shaped recess, where said recess is adapted for a deviating cooperation with a line section located above said lower line section in order to move or lead said line section from the upper region of the pole and to said fixing device at a distance from the pole in order to be able to offer and make possible a pivotal or oscillating movement which is wholly free of contact with the pole and occurring by or caused by air and wind turbulence.
In order to be able to resolve one or more of the above-outlined technical problems, the present invention more specifically discloses that the prior art be supplemented by causing said arm-adapted means to be produced from plastic material and as such be formed as a substantially planar disc in order, in a horizontal plane, to be able to approach a manifest or stylised triangular configuration.
It is further proposed that the portion of the means proximal the pole be able to display a semicircular, or in any event substantially semicircular, recess and that to said portion proximal the pole there is, by the intermediary of discrete fixing means, fixed but readily removably fixable a semicircular, or in any event substantially semicircular, stirrup arrangement.
As proposed embodiments falling within the scope of the basic concept of the present invention, it is moreover disclosed that said groove-shaped recess be formed as a "clinch" arrangement.
In addition it is disclosed that there extends, along a median or the like given triangular configuration for the means, a narrow rigidifying portion with material recesses oriented on each side of said narrow portion.
A further cleat is to be able to be secured to and supported by the narrow portion and where said cleat is to be able to be oriented and fixed to the up- per surface of the triangular configuration.
As one alternative, it is disclosed that said additional cleat is to be able to be oriented to the lower surface of the triangular configuration.
The present invention discloses, in line with its simple form and simple application, that said discrete fixing device may very well be adapted for a coo-
peration each with an associated threaded hole in the outer shanks of the portion proximal the pole.
Said arm-adapted means may, as one proposed alternative construction, consist of a narrow homogenous arm with the stylised tip of the triangular configuration given a small angle and with a curved base given to the triangular configuration associating to an extent equal to or preferably less than selected to be half of the semicircular recess.
A free space is advantageously to be disposed outside the semicircular recess, which free space is adapted in order, in taut line leads, to permit a free passage of an adjacent line section past the arm-adapted means or alternatively to permit a minor deviation of the line leads around said means.
In any event the arm portion for the arm-adapted means display a thin central portion and coordinated flexural stress rigidifying edge portions in the form of walls.
The tip of the triangular configuration is here given an adapted angle value selected between 0 and 30°.
ADVANTAGES
Those advantages which may principally be deemed to be characteristic of the present invention and the specific significative characterising features dis- closed thereby are that there have hereby been created the preconditions in order, in an arrangement adapted for sound damping from the oscillating movement of a line or halliard into contact with and from a pole-shaped device, such as a flagpole, a sail mast or the like, where said line and its lead are to be adapted freely to be able to extend between the upper region of the pole and the lower region of the pole and with a lower line section allocated to the lower portion of said line and fixable to a fixing device, such as a cleat, coordinated with the lower portion of the pole, there being secured, but readily re-
movably coordinated with the pole at an adapted distance along the pole above said fixing device, an arm-adapted means where said means, within its portion proximal the pole, displays a clamping arrangement which may be coordinated with the pole and, within its portion distal from the pole a groove- shaped recess, where said recess is adapted for a deviating cooperation with a line section located above said lower line section in order to move or lead said line section from the upper region of the pole and to said fixing device at a distance from the pole for an oscillating movement free of contact with the pole, to cause an arm-adapted means to be formed as a unit comprising two construction parts, which may be coordinated with one another via discrete fixing means from a plastic material and where one part is given the form of a disc with measures which reduce the plastic material consumption but nevertheless offer for its application a sufficient flexural rigidity and adapted to angle a taut line or line lead in a direction from the pole and with a simple clamp- ing device absorbing flexural stresses for fixedly retaining the arm-adapted means against the pole.
That which may principally be deemed as characterizing the present invention is disclosed in the characterizing clause of the appended Claim 1.

DESCRIPTION OF CURRENTLY PROPOSED EMBODIMENT
It should by way of introduction be emphasised that, in the subsequent description of one currently proposed embodiment displaying the significative cha-
racterizing features associated with the invention and clarified by means of the Figures in the accompanying Drawings, we have selected terms and a specific terminology with a view in such instance of principally clarifying the inventive concept.
It should, however, in this context be observed that expressions selected here should not be seen as restrictive exclusively to the terms used and selected here but it should be understood that every such selected term is to be interpreted so that it, in addition, embraces all technical equivalents which function in the same or substantially the same manner in order thereby to be able to achieve the same or substantially the same intention and/or technical effect.
With reference to appended figures 1 to 9, there is thus illustrated there sche- matically and in detail not only the basic preconditions for the present invention but moreover the significative properties or features associated with the invention have been given concrete form as a result of the embodiments now proposed and described in greater detail hereinbelow.
Thus, Fig. 1 is a side elevation of a flagpole 1 with a flag line or halliard 2 extending with a first line lead 2a upwards towards the top of the flagpole 1a, there being angled at 360° by a pulley, not shown in detail, in order to as a second line lead 2b run downwards towards a cleat 3 and with an arm adapted means 4 adapted where necessary to angle a selected line section 2c from the outer surface 1c of the pole.
Thus, the following description, for purposes of simplification, will utilise expressions such as line leads 2a, 2b for the lines 2, extending upwards and downwards, while the shorter mutually coordinated line leads will be entitled line sections.
More particularly, Fig 1 now illustrates an arrangement "A" in order to damp sound generation from an oscillating movement of line 2 with its line leads 2a, 2b into physical contact with and from the pole-shaped device 1 such as a flagpole, a sail mast or the like, where said line 2 with its two line leads 2a, 2b is adapted freely to be able to extend between the upper portion 1 a of the pole and the lower portion 1b of the pole, and with a line section 2d (Fig. 2) allocated to the lower portion of said line and fixable to a fixing device, such as a cleat 3, coordinated with the lower portion of the pole.
At an adapted distance "a" along the pole 1 , above said fixing device 3, there is secured but readily releasably coordinated with the pole the arm-adapted means 4, where said means, within its portion 4a proximal the pole, displays a clamping arrangement 5 which may be coordinated with the pole 1 and, within its portion 4b distal from the pole, a groove-shaped recess 6, where said recess 6 is adapted to control an angle-deviating cooperation of a selected line section 2c, located above said lower line section 2d in order to move or lead said line lead 2a, (2b), from the upper portion 1a of the pole and to said fixing device 3 at a maximum distance "b" from the pole 1 for a contact free oscillating movement with the pole 1 and its outer surface 1c, 1c'.
According to the specific properties or features of the present invention, said arm-adapted means 4 is to be produced from a plastic material and as such cause its one portion to be superficially formed so as to approximate a mani- fest triangular configuration, clarified in a plan view in Fig. 3 as well as in Fig. 7.
The expression "manifest triangular configuration" has here been put into use in order thereby to illustrate the variations which may be given to the arrange- ment without, to this end, departing from the basic principle of the present inventive concept. Thus, in actual fact, this is a matter of a truncated triangular configuration.
More particularly, it is disclosed that its portion 4a proximal the pole is to display a semicircular, or in any event substantially semicircular, recess 4a' and that to said portion 4a proximal the pole and its outer shanks 4c and 4d there is secured, via discrete fixing means 7, 7a, but readily removably fixed a semicircular, or in any event substantially semicircular, stirrup arrangement 4e.
Said groove-shaped recess 6 is here formed as a "clinch" arrangement.
The term "clinch" arrangement is taken to mean an arrangement with a groove, a channel or a recess for insertion of the line section of a line or a section of a wire. The channel or the recess 6 has an inwardly directed tapering cross section or opening, whereby a line inserted there is fixedly clamped more and more by its own tractive force.
However, the line section may be readily loosened by twisting the line section out of its clamping engagement with the channel or the recess 6.
The form of the alternative construction, according to Figs. 3 to 5, illustrates that, along a median "M" allocated to the triangle configuration there extends a narrow portion 4f with through-going recesses 4g and 4h, oriented on either side of said narrow portion 4f.
A clinch or cleat 8 is secured to and supported by the narrow centrally or- iented portion 4f.
An additional cleat (8) could advantageously be oriented towards and secured to the upper surface 4i of the triangular configuration but according to the special disclosures of the invention such an additional cleat (8) may rath- er be oriented towards and secured to the lower surface 4j of the triangular configuration or disclose an embodiment where both possibilities are utilised.
Said discrete fixing means 7, 7a are adapted for a cooperation with threaded holes 7', 7a' in the portion 4a proximal the pole.
Figs. 3 to 5 then illustrate that the means 4 consists of two plastic parts, a first, designated main part 40, and a second, designated a stirrup arrangement 41 where these two plastic parts are fixedly coordinateable with one another via said discrete fixing means 7, 7a.
The plastic parts 40 and 41 are surrounded by specially formed edges, desig- nated wall portions, where two wall portions 42, 43 are formed for the part 40, while the wall portion 44 is formed for the part 41.
The recesses 4g, 4h may also be surrounded by wall portions, where these wall portions basically are provided in order to allocate the arrangement a sufficient flexural rigidity in the flexural directions where flexural stresses are to be expected.
The wall portions 42 and 43 form, in Fig. 3, an isosceles triangle and create a reinforcement for a thinner centrally oriented part 45, while the wall portion 44 forms an outer semicircular reinforcement of the stirrup arrangement 4e.
The apex of the triangle is here given an angle value "c" of 15-30°, such as for example about 20°.
A second alternative construction is shown and described with reference to Figs. 6 to 9 and which embodiment is advantageously to be compared with the embodiment shown and described in Figs. 3 to 5.
Thus, Fig. 6 illustrates in a perspective view a second alternative construction of the arm-adapted means 4, while Fig. 7 is a plan view of the two parts of
halves 140 and 141 of the arm-adapted means, according to Fig. 6, coordinated with one another via discrete fixing means 7, 7a.
Fig. 8 shows in a side elevation view the arm-adapted means 4, according to Fig. 6, while Fig. 9 is an end elevation view of the arm-adapted means 4 according to Figs. 7 and 8 exposing associated discrete fixing means 7, 7a.
Said arm-adapted means 4 here consists of a narrow arm construction 142 with the outer surfaces or wall portions 143, 144 of the triangular configureati- on forming a tip 4b given a small angle "c" and with a circular curved base 145 allocated to the triangular configuration and associated with an extent of less than half of the semicircular recess 4a 1 or slightly less than half of the semicircular recess.
A free space 146 is disposed immediately outside the semicircular recess, which space 146 is formed and adapted in order, in taut line leads 2a, 2b, to permit a free passage of a line section 2c' to pass the arm-adapted means 4 or alternatively to permit a minor angular deviation around said means.
In any event the part 140 for the arm-adapted means 4 can display a thin central portion 147 and wall portions 143, 144 coordinated therewith.
The part 140 is given an angle "c" for its free end portion of between 0 and 10°, preferably is disclosed an angle value of between 2 and 5°.
It also falls within the scope of the invention to cause the arm and the wall portion 144 to be angled from the median "M" an angle "d" of between 5 and 30°, such as between 10 and 20°. Fig. 7 illustrates an angle value of about 15°.
Otherwise, in Figs. 6 to 9 the same reference numerals have been inserted as in Figs. 1 to 5 for corresponding parts with a view to clarifying the coordination of the invention between the two above described alternative constructions.
The above presented description discloses the utilisation of additional cleats which may also be given the second alternative construction, but it should be observed that these cleats 8, (8) can advantageously be utilised in order to wind up line sections which become dependent of the line configuration which occurs when a flag (or a sail) is raised.
The invention is naturally not restricted to the above embodiments disclosed by way of example but may undergo modifications without departing from the scope of the inventive concept as illustrated in the appended Claims.
In particular, it should be observed that every illustrated unit and/or circuit can be combined with every other illustrated unit and/or circuit without departing from the scope in order thereby to obtain the desired technical function.
