    专利说明:
    [0001] In the building industry, base plates are often used for fixing cables, pipes, ducts and other pieces of this type to a support. [0001]
    [0002] A base plate for attaching a cable, to take an example, comprises a means of supporting the cable and means of attaching the plate to the support. [0002]
    [0003] To attach the base plate to the support, a nailing device which is fitted with a fastener-guide is generally used, the end of which is made integral with the base plate, for instance by driving the end of the fastener-guide into a cutout made to receive it in the base plate. [0003]
    [0004] For safety reasons, the nailing device has a safety system which prevents fastener firing without first pressing the nailing device against a fixing support. [0004]
    [0005] There is however a not inconsiderable risk of unlocking the safety system whilst uniting a base plate and the end of the nailing device's fastener guide, through axial pressure (that is, in the direction of the fastener-guide axis) of the end of the fastener-guide against the base plate. In these conditions, the nailing device may be pulled into support and firing position without being pressed against a support. [0005]
    [0006] The invention aims to overcome this difficulty. [0006]
    [0007] To this end, the invention concerns a method for setting a base plate for fastening a piece to a support, with the aid of a fastener fixing tool fitted with a fastener-guide, during which the base plate and the end of the fastener-guide are firmly fixed together, the base plate is placed against the support and it is fixed there by means of a fastener, the method being characterised by the fact that the base plate and the end of the fastener-guide are firmly united by a relative movement of the base plate and the end of the fastener-guide, the one in relation to the other, in a plane perpendicular to the fastener-guide axis. [0007]
    [0008] This means that, in order to unite the base plate and the end of the fastener-guide, an axial pressure force is no longer exerted, but rather a radial force, such that all risk of unlocking the safety system is avoided. In addition, thanks to the invention, it is possible to reduce the minimum effort required to move the fixing tool into a supported position. Operator fatigue is reduced in this way, for example when setting a base plate onto a ceiling with one hand. [0008]
    [0009] The relative movement of the base plate and the end of the fastener-guide may be a translatory motion, preferably a rectilinear translatory motion. [0009]
    [0010] It is advantageous to achieve firm attachment of the end of the fastener-guide and the base plate by snap fit. [0010]
    [0011] The invention also concerns a tool for carrying out the method defined above, comprising a fastener-guide adapted to be firmly fixed to the base plate, characterised by the fact that, with the base plate being a male part for firm attachment to the end of the fastener-guide, the fastener-guide has a lateral and axial slot for the passage of the base plate. [0011]
    [0012] The invention further concerns a tool for carrying out the method comprising a fastener-guide adapted to be firmly fixed to the base plate, characterised by the fact that, with the base plate being a female part for firm attachment to the end of the fastener-guide, the fastener-guide is fitted with means for locking onto the base plate. [0012]
    [0013] To advantage, the means for locking onto the base plate comprise an exterior annular groove to receive a clamp for snap fitting onto the base plate. [0013]
    [0014] The invention will be better understood with the aid of the following description of the base plate and of the fixing tool of the invention, in a particular form of implementation, and also in a particular embodiment of the method of setting the base plate, with reference to the appended drawing in which: [0014]
    [0015] FIG. 1 represents an overhead view of the base plate, in accordance with the particular form of implementation; [0015]
    [0016] FIG. 2 shows a view from below of the base plate in FIG. 1; [0016]
    [0017] FIG. 3 shows a perspective of the base plate in FIG. 1; [0017]
    [0018] FIG. 4 shows another perspective of the base plate in FIG. 1 assembled onto one end of a fastener-guide and [0018]
    [0019] FIG. 5 shows a cross section of the base plate and of the end of the fastener-guide in FIG. 4. [0019]
    [0020] The base plate, intended here to fix a cable to a support, is formed as a single piece and has an axis [0020] 5 and an axial plane of symmetry P, containing the axis 5, both at right angles to the plane of FIGS. 1 and 2.
    [0021] The base plate has a lower section [0021] 10, a base, for fixing to the support and an upper section 20 for firm attachment to one end of a fastener-guide of a fastener fixing tool. The lower section 10 and the upper section 20 are connected to each other by mating surfaces perpendicular to the axis 5.
    [0022] The lower section [0022] 10, overall in the form of a flat cylinder with axis 5, comprises, on the lower side opposite the upper section 20, a surface 6 for pressing against the support, perpendicular to the axis 5, and has formed in it, on the upper face, a cut-out 1, approximately parallelepipedic in form, with a base 2. A central hole 3, centred about the axis 5, and running through, to accept a fastener, is formed in the base 2, together with two openings 4, 4′, respectively on either side of the plane P.
    [0023] The upper section [0023] 20 comprises two parts 12 and 12′, each in the shape of a section of ring, placed facing each other, on either side of the plane of symmetry P, and thus forming a snap fit clamp 11, for seizing the end of the fastener-guide of the fixing tool. The two parts 12 and 12′ of the clamp 11 produce between them a space 15 to receive the end of the fastener-guide, extending laterally and axially on both sides of the axis 5, via two lateral and axial openings 14 and 14′ respectively for the passage of the end of the fastener-guide.
    [0024] The terms “axial” and “axially” are here intended to describe what extends in an axial plane, in this case for the base plate the plane P containing the axis [0024] 5.
    [0025] Each part [0025] 12, 12′ of the clamp 11 is, in its lower section where it has a junction with the lower part 10, traversed by an aperture 13, 13′ connecting with the cut-out 1 and provided for the passage of a cord for holding the cable to be fixed, and to receive the end of the fastener-guide, as will be explained later.
    [0026] The section of the lower part [0026] 10, situated approximately in the lower extension of each of the parts 12 (12′) of the clamp 11, extends slightly outwards beyond the clamp 11, and presents an upper receiving surface 16 (16′), on the clamp 11 side, to support a cord for holding the cable to be fixed.
    [0027] The fastener fixing tool of the invention, for fixing to a support the above described base plate, differs from a classic fixing tool of the type described in the document FR-9514763, only in certain aspects which will now be described. For the purposes of clarity, only the aspects necessary to the understanding of the invention will be explained. [0027]
    [0028] The fixing tool comprises in the classical manner a fastener-guide [0028] 30 and a safety system.
    [0029] The fastener-guide [0029] 30, extending along an axis 21, is intended to accept a fastener and, after pressing against a fixing support, to guide this fastener propelled forwards when fired, in such a way that it is driven correctly into the support. In order to fix the previously described base plate to a support, the end 23 of the fastener-guide 30 is adapted so that it can be firmly attached to the base plate, as will subsequently be explained in greater detail.
    [0030] The safety system is adapted to lock the tool in rest position and to unlock it when it is pressed against a fixing support, the unlocking taking place under the action of an axial pressure force (that is, parallel to the axis [0030] 21) of the tool against the support. This means that the safety system prevents any firing of a fastener unless the fastener-guide is first pressed against the support.
    [0031] The end [0031] 23 of the fastener-guide 30 has formed in it an outer annular groove 24 to receive and lock the clamp 11 of the base plate. “The end” means here the free end part of the fastener-guide, which is by definition situated at the front of the fixing tool.
    [0032] The front wall [0032] 25 of the groove 24, nearest to the edge of the front free end of the fastener-guide 30, is inclined to the axis 21, the groove 24 flaring out towards the front end of the fastener-guide 30.
    [0033] The section [0033] 22 of the end of the fastener-guide situated between the front edge of the free end of the fastener-guide 30 and the groove 24, in other words in front of the groove 24, has an external diameter smaller than that of the section of the fastener-guide 30 situated behind the groove 24, in order to facilitate the firm attachment of the base plate and the end 23 of the fastener-guide 30.
    [0034] After the structural description of the base plate and of the fastener fixing tool, the method of setting the base plate upon a support [0034] 100 will now be described.
    [0035] In order to place the base plate upon the support [0035] 100, the base plate and the end 23 of the fastener-guide 30 of the fixing tool are first firmly attached, then the base plate is fastened to the support 100 by means of a fastener. Firm Attachment of the Base Slate and the End of the Fastener-Guide
    [0036] In order to fix the base plate and the end of the fastener-guide firmly together, the base plate is assembled onto the end [0036] 23 of the fastener-guide 30 moving the base plate and the end 23 of the fastener-guide 30, the one in relation to the other, in a relative, rectilinear translatory motion, in a plane perpendicular to the axis 21 of the fastener-guide 30, and also to the axis 5 of the base plate. During this movement, the end 23 of the fastener-guide 30 is inserted laterally into the clamp 11 of the base plate, that is into the reception space 15, by passing through one of the lateral and axial openings 14, 14′, so that the axis 5 of the base plate and the axis 21 of the fastener-guide become one.
    [0037] During this translatory movement in the plane perpendicular, to the axis [0037] 21, no axial force, parallel to that axis 21 is exerted, but only a radial force, that is perpendicular to the axis 21, so that there is no risk of unlocking the safety system of the fixing tool.
    [0038] The clamp [0038] 11, accepted into the groove 24, seizes and grips the end 23 of the fastener-guide 30, the clamp 11 and the fastener-guide 30 becoming thus solidly fixed together by snap fit. The annular peripheral section of the front part 22 of the end 23 of the fastener-guide 30 is partially inserted into the apertures 13, 13′ of the base plate and the rear wall of the groove 24 rests against the upper surface of parts 12, 12′ of the clamp 11. In this position, the groove 24 locks the base plate in, making difficult any relative movement of the base plate and the end 23 of the fastener-guide 30 in relation to each other, in translatory motion parallel to the merged axes 5 and 21.
    [0039] We stress here that the base plate is a female part and the end [0039] 23 of the fastener-guide 30 is a male part for the firm uniting of the one with the other. Fixing the Base Plate to the Support
    [0040] After fixing the base plate to the end [0040] 23 of the fastener-guide 30, the base plate is applied against the support 100 along its support surface 6, the fixing tool is pressed against the support 100, exerting an axial pressure force against the support 100, which unlocks the tool via the safety system, then a fastener is fired using the tool. Since the axis 21 of the fastener-guide 30 and the axis 5 of the base plate are one, the fastener is driven into the support 100, through the hole 3, and fastens the base plate to the support 100. Release
    [0041] After fixing, the fastener-guide [0041] 30 is released by separating it from the support 100. During release, the fixing tool is pulled backwards, in an axial direction (parallel to the axes 21 and 5) opposite to that of the firing, thus withdrawing the end 23 of the fastener-guide 30 from the base plate. We emphasise that the withdrawal of the end 23 from the base plate is facilitated by inclination of the front wall 25 of the groove 24. Fixing the Cable
    [0042] Finally, in the known manner, a section of the cable to be fixed is inserted between the two parts [0042] 12, 12′ of the base plate clamp and into the lateral openings 14. 14′, and the cable is fixed to the base plate with the aid of a cord which is inserted into the receiving apertures 13, 13′ and which is bound round the cable.
    [0043] In the description just given, the base plate and the end of the fastener-guide constitute a female part and a male part respectively, for the purpose of firmly uniting the one with the other. [0043]
    [0044] In another embodiment, not differing from that described above, the base plate constitutes a male part and the end of the fastener-guide a female part for the purpose of firmly uniting the one with the other. The base plate has means for preventing the fastener-guide from moving in a translatory manner parallel to its axis and the end of the fastener-guide has formed in it means for receiving the base plate comprising a lateral and axial slot for the passage of the base plate. [0044]
    [0045] It is equally possible to envisage firmly uniting the base plate and the end of the fastener-guide by a curvilinear translatory movement or by any other relative movement of the base plate and the end of the fastener-guide, the one in relation to the other, in a plane perpendicular to the axis of the fastener-guide.
