Definitions

  • the present invention relates to a rake assembly and then particularly but not exclusively to a rake assem ⁇ bly that is comprised of a handle and a rake unit attached to one end of the handle by means of a pivot arrangement such as to enable the rake unit to be brought to a position in which it extends transversely to the handle in readiness for its intended function and to a position in which the rake unit extends parallel with the shaft in an in-folded or collapsed stowing position.
  • This known rake assembly is comprised of a rake handle and a rake unit which is affixed to one end of the handle.
  • the rake unit is comprised of two parts, each of which is pivotally attached to bracket means by means of a respective pivot shaft.
  • the bracket means are secured to one end of the handle in a manner which enables the two parts of the rake unit to be moved between positions in which they extend transversely to the handle, and locked in said position, and a posi ⁇ tion in which they extend parallel with the handle.
  • This arrangement does not enable the rake-parts to be inclined to any desired position in relation to the handle axis.
  • the front part of the rake handle is flat ⁇ tened so as to be able to hold bracket means adapted for pivotal coaction with the inner parts of said rake-parts.
  • Another technical problem is one of providing a fold ⁇ able rake assembly which, when folded, will have external dimensions that enable the rake to be placed in a golfer's bag.
  • Another technical problem is one of realizing the possibilities that are afforded when the rake handle is made telescopic, with the telescopic sections capable of being locked relative to one another in any desired position.
  • Another technical problem is one of creating condi ⁇ tions with the aid of simple means that will enable the width of the rake to be adapted to all occurring situations with the aid of simple means, by extending a rake unit or a rake unit comprised of several parts to a width suitable for the task on hand.
  • Another technical problem is one of realizing the possibilities that are afforded when the rake unit or the rake-unit parts can be brought to an angled posi- tion, and thereby enable the distance between the prongs of the rake-unit, as seen relatively, to be selected arbitrarily when moving the rake, and to enable the total width of the rake unit to be adjust ⁇ ed.
  • this distance can be chosen in relation to respective units.
  • a technical problem resides in the creation of conditions with the aid of simple means which will enable the rake-unit, either a single or two-part unit, to be brought to desired angular positions , so as to provide a raking function in one selected angu- lar position with an adapted smaller or greater dis ⁇ tance between the prongs of the rake-unit and the width of the rake-unit in accordance with an occurrent situation in a sand bunker.
  • a technical problem resides in realizing the significance of providing a rake-unit in which a pivot shaft is common to two raking-unit parts, or to provide a pivot shaft for each rake-unit part, where a selected pivot shaft is located close to the end of the rake handle.
  • Another technical problem is one of realizing the significance of providing for golfers a rake assembly in which the rake handle is telescopic and comprises at least two telescopic sections, which can be locked in a fully inserted and fully extended position and in each position therebetween.
  • a further technical problem resides in realizing the significance of locking and holding the rake-parts in a selected angular position relative to the handle axis with the aid of a locking device that can be moved axially along the rake handle.
  • Another technical problem is one of realizing the simplicity of allowing each of the two rake-parts to coact with a brace or strut which is pivotally at ⁇ tached to a respective rake-part and to the locking device.
  • the rake assembly and/or the rake handle can be used for several different purposes, in which case a technical problem is one of realizing that the rake-unit or those parts belonging to the rake-unit shall be attached to the end of the rake handle in a manner to form an opening in which there can be firmly but detachably fitted a further tool, such as a ball retriever or catcher, which can be used to retrieve a golf ball that has fallen in to a water trap or like water obstacle.
  • a further tool such as a ball retriever or catcher
  • the rake-unit is comprised of a single part which is attached to the end of the handle by means of a single pivot shaft such as to enable the rake-unit to be brought to a position transversely to the handle axis and a position in which the rake-unit lies paral ⁇ lel with said axis
  • the pivot shaft should be spaced from the end surface of said handle at a distance which corresponds to 10-40% of the total length of the rake-unit
  • the rake handle will preferably consist of at least two telescopically mounted parts so as to enable the rake to be adapted to requirements occurrent in the game of golf.
  • the present invention provides a solution to one or more of the aforesaid technical problems and takes its starting point from the known standpoint of techniques in which a rake assembly of this kind is comprised of a rake handle and a rake-unit coacting with one end- part of the handle, wherein the rake-unit is attached to said end-part by means of at least one pivot shaft in a manner which enables the rake-unit to be brought to a fixed position transversely to the rake handle and a position in which the rake-unit lies parallel with said handle.
  • the rake assembly is comprised of a two-part rake-unit and means for folding the two rake-unit parts in selected pivoted positions in which the rake affords one raking function and therewith enable the relative distance between the prongs of the rake-unit, as seen in a direction parallel with a centre line on the rake handle, and the total width of the rake-unit to be adapted.
  • the parts of said rake-unit shall be pivotally mounted on a common pivot shaft or about individual pivot shafts located very close to the end of said handle.
  • the rake handle is telescopi- cally constructed from two or more telescopic sections and can be locked in a fully inserted or partially inserted or extended position.
  • a pivot ⁇ ally mounted brace or strut extends between each of the two rake-parts and a locking device which is movable along the rake handle.
  • the locking device is preferably constructed so that it can be activated and deactivated by twisting the device around a centre line on the rake handle.
  • the rake-unit or rake-parts is/are attached to the end of the handle in a manner to form an opening through which a further tool, such as a ball retriever, can be easily attached to the rake and detached therefrom.
  • This further tool may be attachable to a telescopic rod housed in the rake handle.
  • the rake assembly comprises a single-part rake- unit
  • this single pivot shaft being located at a position on the handle which corresponds to 10 to 60% of the length of the rake-unit from the end surface of the shaft, and the shaft is preferably comprised of at least two tele- scopic sections.
  • a collapsible and extendable rake which comprises a handle and a rake-unit and which is well adapted for storage in a golfer's bag and can be used readily in sand bunkers and the like. Naturally, the rake can also be used for other purposes.
