Definitions

  • the present invention relates to a connection for detachably locking different parts on a broom handle or similar work tool, such as a handle part and a tool part, where the connection comprises an outer element on the one part and an inner element on the other part, the inner element being inserted into the outer element when the parts are coupled together, like tubes of different diameters, the outer element comprising radially directed locking grooves and the inner element comprising one or several outwardly spring-loaded locking dowels, which, in the locked position, engage the locking grooves of the outer element, as well as one or several control buttons, which, for disengagement, are depressed towards the inner element, whereupon the locking dowels are released from the locking groove and the inner element can be extricated from the outer element.
  • connection is commercially available in which the handle part is provided at its lower end with a threaded element that is screwed onto a corresponding threaded element on the tool part.
  • the most common connection is a type where the handle part is provided at its lower end with an outer element, usually in the form of a tube, with a circular cross-section, into which an inner element, cohesive with the tool part or the intermediate part, can be inserted.
  • the inner element is most commonly fashioned as a tube with an outer diameter slightly smaller than the inner diameter of the outer element.
  • the tool part is provided with an outer element into which an inner element on the lower end of the handle part can be inserted.
  • a cotter joint which in its simplest form consists of a pin inserted from the outside through radially directed grooves in the inner and the outer elements. This provides a secure and cheap coupling but has the disadvantage that the pin easily can be lost when the coupling is opened.
  • Its inner element comprises a separate locking member in the form of a U-shaped spring piece, which is provided at it ends with outwardly directed locking dowels, the upper/outer ends of which act as control buttons.
  • the locking member is inserted into a cavity in the inner element, which is provided with radially directed guide grooves for the locking dowels.
  • the locking dowels thus protrude through the envelope surface of the inner element and are influenced by an outward radial force from the U-spring.
  • the locking dowels also comprise an inner part with a cross-section greater than that of the guide groove. Actuated by the spring force, the locking dowels are thus pressed towards an outer locking position.
  • the outer element is provided with corresponding radially directed locking grooves.
  • the inner element When a tool part is being connected, the inner element is inserted into the outer element in the axial direction up to the position where the locking dowels encounter the outermost edge of the outer element. The locking dowels are then pressed in towards the centre of the inner element. The upper parts of the locking dowels then serve as control buttons for the thumb and an opposite finger of the operator. The inner element is simultaneously inserted into the outer one, whereupon the control buttons slide into the space between the inner and the outer elements. Thereafter, the inner element is displaced/ turned to the locking position, whereupon the control buttons and the subjacent locking dowels are pressed out by the spring through the locking grooves in the outer element.
  • a work tool according to the preamble of claim 1, is disclosed, in US-A-4 247 216 ; a similar device is known from US-A-2 501 940 ,
  • US-A-5 462 380 discloses a detent for releasably securing an inner telescoping tube with an outer telescoping tube wherein the tubes have alignable openings in the walls thereof for receiving the detent.
  • the detent is formed by a detent pin which extends through the tube wall openings and releasably latches the tubes together wherein a leaf spring is secured at the inserted end into supporting and biasing engagement with the detent pin.
  • the primary object of the present invention is to provide a connection in accordance with the preamble that can be manipulated without risk of injury to the operator.
  • Another object of the invention is to provide a connection that is easy to access and to manipulate.
  • Yet another object of the invention is to provide an efficient connection that can be manufactured at a low cost.
  • the invention provides a connection for detachably locking different parts on a broom handle or similar work tool, such as a handle part and a tool part, where the connection comprises an outer element on the one part and an inner element on the other part, the inner element being inserted into the outer element when the parts are coupled together, like tubes of different diameters, the outer element comprising radially directed locking grooves and the inner element comprising one or several outwardly spring-loaded locking dowels, which, in the locked position, engage the locking grooves of the outer element, as well as one or several control buttons, which, for disengagement, are depressed towards the inner element, whereupon the locking dowels are released from the locking groove and the inner element can be extricated from the outer element, the control buttons being completely or partially located outside the space between the inner and the outer elements when these elements are inserted into or extricated from each other.
  • the invention can be applied to all kinds of tools provided with a handle where there is a need to be able to change the tool part easily, such as gardening tools, paint shanks and the like.
  • the primary area of application is broom handles for floor and window cleaning and particularly those intended for dry and wet mopping of floors.
  • Figure 1 shows a broom handle for dry mopping of floors, the tool part 4 being disengaged from the handle part 1, only partly shown.
  • the lower end of the handle part 1 comprises a tubular outer element 2, provided with radially directed locking grooves 3 in the form of two through-running opposite holes in the envelope surface.
  • An inner element 5 is connected to the tool part with conventional cardanic suspension.
  • the handle part comprises the outer element and the tool part the inner element, but the opposite can also be the case, of course.
  • FIGS 3-7 show a preferred embodiment of the essential parts of a connection in accordance with the invention.
  • the outer element 2 consists of a tube with a circular cross-section.
  • the material can be metal or reinforced plastic.
  • Locking grooves 3 are cut out near the end.
  • the locking grooves consist of holes that pass through the envelope surface of the outer element on two opposite sides in a conventional way. These locking grooves are made by drilling or punching and thus acquire unavoidably sharp edges, at least on one side.
  • An inner element 5, suitably manufactured of injection-moulded plastic comprises a tube part 12 with a circular cross-section having an outer diameter slightly smaller than the inner diameter of the outer element 2.
  • a groove 7 is cut through the envelope surface of the tube part 12 in such a way that a tongue is formed.
  • This tongue comprises a spring 6, fashioned in one piece with and of the same material as the tube part 12, an outwardly radially directed locking dowel 8 with a shape adapted to the locking groove 3, and a control button 10, cohesive with the locking dowel 8 by way of an arm 9.
  • the control button 10 can be provided with coring-out to reduce the material thickness, thus facilitating manufacture.
  • the rear tube part 11 of the inner element 5 has an outer diameter that is suitably greater than the tube part 12 and thus forms a stop edge when the inner element 5 is inserted into the outer element 2.
  • the front edge of the control button 10 is located level with the front edge of the tube part 11 and will therefore always be easily accessible outside the outer element 2.
  • the inner element 5 has the same locking device on the opposite side with a spring 6, a locking dowel 8, an arm 9, and a control button 10, as illustrated in Figures 5 and 7 , so that a double locking mechanism is provided, but one or more than two locking devices can obviously also be considered.
  • An essential advantage of an inner element 5 in accordance with the description, where the spring 6, the locking dowels 8, and the control button 10 are manufactured in one piece with the inner element, is that the production costs are reduced considerably. The reason for this is that no separate locking member has to be manufactured, stocked, or assembled.
  • the locking member is manipulated outside the outer element in accordance with Figure 8 .
  • the inner element 5 is inserted, in the axial direction, into the outer element 2, at the same time as the control buttons 10 are depressed towards the centre in the direction of arrows A.
  • the locking dowels 8, acted upon by the arms 9, are then also depressed in towards the centre to such a position that they can freely clear the space between 15 between the inner and the outer elements, as shown in Figure 9 .
  • the inner element 5 is displaced / turned to the locking position, whereupon the locking dowels 8 are pressed out, by the spring, through the locking grooves 3 in the outer element 2, which is illustrated in Figures 10 and 11 .
  • the anterior edge of the outer element 2 is upset outwards or worked in some other way so that a bevelled entry for the locking dowels is formed, which is not shown in the drawings.
  • the inner element 5 can then be displaced to the locking position without the control buttons 10 having to be depressed towards the centre.
  • the control buttons 10 are depressed in towards the centre of the inner element 5, whereupon the locking dowels 8 are released from the locking grooves 3 and the inner element 5 can be withdrawn from the outer element 2.
  • the control buttons 10 remain outside the space 15 between the inner element 5 and the outer element 2.
  • buttons 10 can therefore be manipulated by the fingers of the operator without any risk of injury. Moreover, they can be made higher and designed with a greater and more comfortable depression surface than would otherwise be possible. Besides the risk of injury being eliminated, they thus become more easily accessible and easily manipulated than known commercially available alternatives.
  • FIG 12 shows various views, in accordance with European viewpoint conventions, of a separate locking member 17.
  • the locking member 17 is suitably manufactured of injection-moulded plastic and consists, in its essence, of a U-shaped spring with locking dowels 8 and control buttons 10 at both free ends of the spring 6.
  • the depression surface of the control buttons 10 extend towards the locking dowels 8 in a tapered portion 19. Stop surfaces 22 are fashioned below this portion 19.
  • Coring-outs 18 are located on the underside of the control buttons 10, which is advantageous for production-engineering reasons.
  • the locking member 17 is primarily intended for inner elements 5 manufactured of metal tubes, which cannot easily be provided with locking members fashioned in one piece with the same.
  • the inner element 5 is provided with an axially directed guide groove 20, suitably by punching.
  • Figures 15 and 16 show a ready-assembled inner element 5, where the locking dowels 8 and the control buttons 10 are situated in the guide groove 20, with some clearance, and, actuated by the spring 6, are pressed to an outer locking position defined by the stop surfaces 22.
  • Figures 17 and 18 show an outer element 2 and an inner element 5 in accordance with the above, in a preparatory assembly position.
  • the locking groove 3 is provided with a gap 21, which gap constitutes an opening between the end of the outer element and the locking groove.
  • the gap 21 is designed such that it corresponds, with suitable clearance, to the portion 19 on the control button.
  • control buttons 10 are closer to the locking dowels 8, without having to be pressed into the space between the inner and the outer elements during the assembly procedure.
  • the gap 21 acts as a guide during engagement, making it easier to find the locking position.
  • the control buttons 10 are depressed in the direction of arrows A, whereby the locking dowels 8 are depressed to such a position that they can freely clear the space 15 between the inner and the outer elements.
  • the inner element 5 is inserted into the outer element 2 to a locked position in accordance with Figure 20 , whereupon the locking dowels 8 are pressed out, by the spring 6, through the locking grooves 3 in the outer element 2.
  • the control buttons 10 are depressed towards the centre as previously.
  • the locking dowels 8 are thereby released from the locking grooves 3 and the inner element 5 can thereafter easily be withdrawn from the outer element 2.
  • This coupling also exhibits the advantage of easy and safe manipulation, as the control buttons 10 remain located outside the space 15 between the inner element and the outer element during engagement as well as during disengagement.
  • a further advantage of a separate locking member 17 in accordance with the above is that it can be assembled on inner elements 5 of varying shapes and dimensions, whereby investment costs for the means of production can be reduced.
  • the control button 10 comprises a section that remains located axially outside the end of the outer element in the connected position, as previously described.
  • the control button 10 is fashioned as a narrow rod that is long in the axial direction and placed above the locking dowel 8, as an extension of the tapered portion 19 in accordance with Figure 12 . If the thus rod-shaped control button 10 is narrower than the locking dowel 8, the control button can pass freely through a gap 21 between the locking groove 3 and the end of the outer element 2 without impairment to the operation of the lock.
  • the control button 10 has a smaller depression surface than in the embodiments previously described. However, during engagement as well as during disengagement, the depression surface on the control button remains located radially outside the space 15 between the inner element and the outer element. Thus, this embodiment also exhibits the significant advantage of easy and safe manipulation.
  • Figures 21 and 22 show an inner element 5 with a spring 6 and a locking dowel 8, in one piece with the same, in accordance with the embodiment depicted in Figures 4 and 5 .
  • the locking dowel is manipulated by way of its upper part acting as a control button in accordance with known technology. This design is still superior as regards production technology to commercially available alternatives.
  • Figures 23 and 24 show coupling devices, comprising an inner element 5 at one end and an outer element 2 at the other end. These two elements are joined in one piece with a conical part 22.
  • the coupling device is manufactured of a metal tube that has been tapered down to an inner element 5 and provided with a separate locking member 17 as previously described.
  • the coupling device is manufactured of injection-moulded plastic, with a locking member 6, 8, 9, 10 in one piece with the inner element 5 as previously described.
  • the outer element is provided with a locking groove 3 as previously.
  • Such coupling elements can be permanently connected to parts, often tool parts, with inner elements of a conventional design, such as are in use in great numbers. Thereby, these parts can also be easily and safely connected and disengaged.
  • a tool known as a rack
  • the rack is attached to the connection part with a gimbal mount that enables rotation of the rack while the same is in contact with the floor.
  • the rack is thus pivoted in relation to the handle with two axes that are at 90 degrees to each other.
  • Figures 25 and 26 show a rack 51 attached to a connection part 5 via a gimbal mount 52.
  • This consists of an attachment piece 53, which is screwed onto the rack.
  • the attachment piece 53 is provided with two opposite bottom holes into which corresponding pins 55 are received.
  • These pins 55 are attached to a universal joint 54, which universal joint can thus rotate in the direction of arrow B.
  • the universal joint 54 is provided with a hole, the centre line of which is turned 90 degrees relative to the axis of the pins 55.
  • a shaft 57 is inserted into the hole, which shaft is attached to a fork 56, whereby the fork 56 can rotate in the direction of arrow A.
  • a blocking member in the form of a T-shaped metal piece, the shaft of which is introduced into a central hole in the connection part 5 is commercially available.
  • the metal piece is pulled out towards the universal joint and locked by turning the metal piece, whereby locking shoulders engage the underside of the connection part 5.
  • a device in accordance with the invention which consists of a blocking member 58, pivotably attached to the underside of the connection part 5.
  • the fork 56 is thus provided with protrusions 59, forming an internal cylindrical envelope surface.
  • a cylindrical peg 60 is inserted into this surface, which peg constitutes the upper part of the blocking member 58.
  • These parts 58 and 59 can easily be manufactured of reinforced plastic by using an uncomplicated injection-moulding tool or, with minor modification, the existing injection-moulding tool for the connection part 5.
  • the blocking member 58 is also particularly easy to assemble, as it can be introduced from the side. Thus, the assembly process can easily be automated, which is desirable, bearing in mind the large volume of such tools that are manufactured.
  • the manufacturing costs are 25 per cent of the costs for existing blocking members.
  • manipulation is easy.
  • the blocking member 58 is turned down towards the universal joint 54, as illustrated in Figures 27 and 28 .
  • the lower locking surface of the blocking member thereby engages the upper surface of the universal joint, thus preventing rotation in the direction of arrow A in accordance with Figure 25 .
  • the manipulation process is easily comprehensible.
  • This embodiment is preferred, as it does not prejudice the mobility of the gimbal mount, but a pivotable blocking member attached to the upper surface of the universal joint is, of course, also conceivable, which member acts upon one of the legs of the fork 56 or upon the underside of the coupling member 5.
  • Figures 29-35 show an embodiment with a separate locking member 17 that is fitted into an externally open groove in the inner element 5.
  • the locking member is easily assembled and can be manufactured so that pre-tensioning is provided when it is fitted into the outer element 2, which is difficult to achieve if it is manufactured in one piece with the inner element.
  • the locking member in accordance with Figures 12-20 also exhibits these desirable qualities, but in that embodiment the locking member is mounted by being pressed together and introduced into the space 13 in the inner element 5 in accordance with Figures 13 and 14 .
  • the outer diameter of the inner element 5 is standardized at 20 mm in large parts of the market for broom handles, the width and height of the control buttons 10, which must fit inside the space 13 during assembly, are thereby limited.
  • Figure 29 and the left part of Figure 32 show a separate locking member, somewhat pulled apart, with a substantially U-shaped spring 6 and locking dowels 8 and control buttons 10 at both free ends of the spring 6.
  • the locking member is further provided with protrusions 71 and a guide groove 75.
  • the locking member 17 is suitably manufactured of injection-moulded plastic.
  • Figures 30 and 31 show an inner element 5 with a dowel-shaped end 70, intended to be inserted into an outer element 2. The cross-section of the end 70 is thus fashioned so that is fits into the desired outer element.
  • Figures 30 and 31 show a circular cross-section. This cross-section is interrupted by outwardly open longitudinal grooves 73, intended for the locking member 17.
  • the end 70 is thereby fashioned as an H-beam, the outer end of the waist 74 of which acts as a guide edge for the guide groove 75 of the locking member 17. Furthermore, the guide groove 73 is provided with lateral groove 72, adapted to the protrusions 71 of the locking member 17.
  • Figure 32 shows a preparatory assembly position, where the locking member 17 is somewhat pulled apart so that the protrusions 71 can be displaced across the edges of the groove 73 up to the lateral groove 72. During assembly, the waist 74 is guided into the guide groove 75.
  • Figure 33 shows a view, partly sliced through, of an inner element 5 and a ready-assembled locking member 17, here shown in its uninfluenced span, which causes certain pre-tensioning during introduction into the outer element.
  • Figure 34 shows a view from above of details i n accordance with Figure 33 .
  • the protrusions 72 are introduced into the lateral grooves 72.
  • the locking member is thereby secured to the inner element 5 and cannot be disengaged from the same without the two ends of the locking member being pulled apart.
  • the guide groove 75 fitting onto the waist 74 the one end of the locking member will be unaffected if the other end is pulled out or depressed.
  • This arrangement provides a secure coupling of the locking member 17 to the inner element, albeit that the assembly is easy to execute.
  • the control buttons 10 can thereby be made as high and as large as desired without assembly being obstructed.
  • the lateral grooves 72 are deeper than the protrusions 71, as shown in Figure 33 .
  • the spring 6 of the locking member 17 can thus be inflected inwards when the control buttons 10 are compressed in the direction of arrows C in accordance with Figure 35 .
  • the locking dowels 8 are thereby depressed towards the centre of the end 70 to such a position that the outer element 2 can be connected to the inner element 5 as previously described.
  • Figures 36 to 43 describe example of a coupling useful for understanding the invention that makes large control buttons possible, despite the locking member being inserted into a tube part 12 on an inner element 5.
  • Figure 36 shows a standard inner element 5 where the tube part 12 is provided with axially directed guide grooves 20.
  • the inner element has been provided with an assembly groove 80 for a separate locking member 17 in accordance with Figures 38-40 .
  • the locking member 17 is suitably manufactured of injection-moulded plastic and is provided with a spring 6 and with locking dowels 8 and control buttons 10 at both free ends of the spring 6.
  • the control buttons 10 are connected to the locking member 17 by arms 9, which are laterally displaced so that they pass each other when the control buttons are compressed.
  • This lateral displacement illustrated in Figure 39 , enables the arms to be so high that sufficient bending strength is achieved without assembly being obstructed.
  • Figure 41 shows how the locking member 17 is introduced into the inner space 13 of the tube part 12 via the assembly groove 80. The locking member is therefore assembled from the end on the inner element that faces away from the outer element in the connected position.
  • the control buttons 10 do not have to pass through the tube part 12.
  • the control buttons 10 are depressed towards each other, whereby the arms 9 proceed past each other.
  • the locking dowels 8 thereby come so close to each other that assembly is possible.
  • control buttons 10 are not introduced into any space whatsoever and their size is therefore not limited by the assembly process.
  • Figure 42 shows the locking member in its assembled position, somewhat compressed compared with its uninfluenced position in Figure 38 .
  • the locking dowels 8 are therefore pressed outwards through the guide grooves 20 with a certain pre-tensioning and are therefore able to lock into an outer element in like manner as in previously described embodiments.
  • Figure 43 shows how the compression of the control buttons 10 in the direction of the forces F presses the locking dowels 8 down into the guide grooves 20, whereby an outer element can be disengaged in like manner as in previously described embodiments.
  • Figures 44-49 show variations on the invention where the locking dowels 8 are turned inwards.
  • An inner element 5 in accordance with Figure 44 is provided with a tube part 12 comprising radially directed guide grooves 20 for connection to an outer element. Furthermore, the inner element comprises a guide groove 80 and attachment grooves 81 for receiving a locking member 17.
  • Figures 45 and 46 show the inner element 5 in accordance with Figure 44 with an assembled locking member 17.
  • This locking member 17 is suitably manufactured of injection-moulded plastic and comprises locking dowels 8 that are turned inwards, towards each other, and that are inserted into the guide grooves 20.
  • An outer element 2 can thereby be coupled with the inner element via radially directed locking grooves 3.
  • Figure 46 shows such an outer element 2 with the tube part 12 partly inserted into it, in the unlocked position.
  • the locking member 17 comprises arms 9, which connect the locking dowels 8 with the locking member, and swivels 82, which in this embodiment are 4 in number.
  • the swivels 82 are pivotably journalled in the attachment grooves 81.
  • the locking member further comprises a V-shaped spring 6 and control buttons 10.
  • this locking member 17 has a smaller reach in its unassembled state so that a certain pre-tensioning is provided when it is assembled on the inner element.
  • the locking member 17 is secured against lateral displacement by the guide groove 80.
  • the fit into the guide groove is provided with some clearance, however.
  • the arms 9 and the spring 6 can thereby move during manipulation.
  • Figure 47 shows the locking member in its influenced position. Actuated by the compressing forces from the fingers of the operator in the direction of arrows F, the spring 6 is deformed and the arms 9 are turned by way of the journalling of the swivels 82 about their respective attachment grooves 81. The locking dowels 8 are thereby raised from their locked position and an outer element 2 can be slid onto or pulled off the tube part 12.
  • Figure 47 shows an outer element arranged for coupling, with the locking grooves 3 aligned with the guide grooves 20. Actuated by the spring 6, via the arms 9, the locking dowels 8 will therefore be depressed through the locking grooves 3 and the guide grooves 20, when the control buttons 10 are released, thus providing a reliable but easily manipulated coupling.
  • the swivels 82 can be snapped into the attachments grooves 81 or be secured in any other known way against outward displacement in the radial direction, for instance by replacing the swivels 82 of the locking member 17 and the attachment grooves 81 of the inner element 5 with holes for the fitting of shafts for the arms 9 to pivot about.
  • Figure 48 shows a variation of the locking member 17, journalled in the inner element 5 in a way similar to that described above and with the same manipulation properties, but where the integrated spring 6 has been replaced by a separate spring element 83, for instance a helical spring, a laminated spring, or a rubber spring element.
  • FIG. 49 shows a variation with the same arrangement as previously with inwardly-turned locking dowels, but where the locking member is disposed on an outer element 2 with a tube part 84 comprising guide grooves 20.
  • an inner element 5 with guide grooves 3 can be introduced and coupled to the outer element 2 by the operation of the locking dowels 8, which form part of locking members in accordance with one of the variations described above or in some other way that is obvious to those skilled in the art.
  • Figure 49 describes a design where the locking member is mounted on an outer element, which is connected to the tool part, but a similar arrangement where a locking member with inwardly-turned locking dowels is mounted on an outer element that is connected to the handle part is, of course, also conceivable.
