Description

(54) FASTENER FOR PANEL MOUNTING (71) We, UNITED-CARR LIMITED, a British Company of 57 Chiswell Street, London EC1Y 4FY, England, do hereby declare the invention, for which we pray that a patent may be granted to us and the method by which it is to be performed, to be particularly described in and by the following statement:- The present invention relates to a fastener for mounting an apertured member on a support.
We have found that there is a need for a fastener for mounting a printed circuit board on a support panel which gives a positive retention for the board on the support but which enables the board to be relatively easily released and removed from the support.
When a fault occurs in a television set, it is often necessary to remove one or more of the printed circuit boards for testing or repair.
Hitherto the printed circuit boards have been mounted on a support frame of the set by conventional fasteners such as screws or snap-in studs.
These conventional fasteners have either been difficult to remove or have been too readily removable and have not therefore provided a sufficiently secure mounting for the printed circuit board on the support frame. It is therefore an object ofthe present invention to provide a fastener for mounting an apertured member such as a printed circuit board on a support frame which will provide a positive retention but which enables the apertured member to be quickly and easily removed when required.
According to one aspect of the present invention we provide a fastener for removably mounting an apertured member on a support, the fastener comprising a base, means on one side of the base for mounting the fastener on a support and, projecting from the opposite side of the base, two legs which are spaced from one another and which extend generally in parallel away from the base, one of the legs being substantially longer than the other, the shorter leg being substantially rigid and having an outer face remote from the longer leg and substantially plain and the longer leg being deflectable towards the shorter leg and formed with a shoulder having an abutment surface facing the base and positioned on the side of the longer leg remote from the shorter leg.
In use, a number of the fasteners of the present invention are mounted on the support frame in a position corresponding to the apertures in the member to be mounted on the support frame with the legs projecting outwardly from the support frame. The member which may for instance be a printed circuit board, is then brought up to the support frame so that the legs of each fastener locate through one of the apertures in the printed circuit board. The printed circuit board is then pressed home so that the longer leg of each fastener is deflected until the shoulder of each longer leg snap-engages behind the printed circuit board to secure the printed circuit board on the support frame.
If at any time it is desired to remove the board, the longer leg of each fastener is manually deflected towards the shorter leg so as to disengage the shoulder from the edge of the aperture in the board. The board can then be freely removed from the support frame.
A preferred form of the present invention will now be described with reference to the accompanying drawings in which: Figure 1 is an elevation of a fastener according to the present invention Figure 2 is a side elevation of the fastener shown in Figure 1; Figure 3 is a plan view of the fastener shown in Figure 1; Figure 4 is an elevation, partly in section showing a printed circuit board mounted on a support frame with the aid of a plurality of fasteners of Figure 1 to 3; Figure 5 is an elevation, partly in section showing a modification of the fastener of Figures 1 to 4; and Figure 6 is an elevation, partly in section showing a further modification of the fastener of Figures 1 to 4.
In Figures 1 to 4 a fastener is indicated generally at 10 which is formed from any suitable synthetic plastics material, such as nylon, by injection moulding. The fastener 10 comprises a base 11, a stud 12 and two lets 13 and 14.
The base 11 comprises a bowed plate 15 and a spacing member 16 which projects from one side of the plate 15. The spacing member 16 is cruciform in cross-section and serves only to space the legs 13 and 14 from the plate 15.
The stud 12 projects from the concave side of the plate 15, that is the opposite side of the plate 15 to the spacing member 16. The stud 12 comprises a central stem 17 and two flexible wings 18 and 19 which are joined to the nose of the stem and which extend from the nose of the stem rearwardly towards the plate 15.
The wings 18 and 19 are formed with abutment surfaces 20 and 21 respectively which face the concave surface of the plate 15.
The legs 13 and 14 project from the end of the spacing member 16 remote from the plate 15. The legs 13 and 14 are spaced apart but extend generally in parallel away from the spacing member 16. The leg 13 is substantially shorter than the leg 14 and has an inclined leading face 22 which assists in leading the legs into an aperture. The longer leg 14 has a shoulder 23 which forms an abutment surface 24 which is spaced from but faces the spacing member 16. The leg 14 is tapered from the shoulder 23 towards its leading end 25.
The fastener 10 is designed to mount a printed circuit board 30 on a support frame 31 as shown in Figure 4. The support frame 31 is formed with a plurality of circular apertures 32 appropriately positioned in the support frame. A fastener 10 is mounted in each of the apertures 32 by inserting the stud into the aperture. The diameter of the aperture 32 is such that the wings 18 and 19 of the stud 12 are flexed inwardly and then sanp outwardly so that the abutment surfaces 20 and 21 locate behind the support frame 31 and locate the fastener permanently on the support frame 31. The plate 15 is flattened slightly against the support frame 31 to ensure a firm and rattle-free mounting of the fastener on the support frame.
The printed circuit board 30 is formed with a plurality of apertures 33 which correspond to the apertures 32 in the support frame 31.
In order to attach the printed circuit board 30 to the support frame, the board 30 is brought up to the support frame so that the legs 13 and 14 of each fastener are located through an aperture 33 in the board 30. The inclined face 22 of the leg 13 provides a lead-in to the aperture 33. As the legs enter the aperture 33, the longer leg 14 is bent towards the shorter leg 13 until the shoulder 23 snaps through the aperture. The abutment surface 24 then secures the board 30 against the spacing member 16 of the fastener to securely mount the board on the support frame 31. The shorter leg 13 is so positioned that it engages the oppcsite side of the aperture 33 so as to locate the legs 13 and 14 correctly and ensure that the abutment surface 24 of the longer leg 14 is urged into tight enggement against the rim of the aperture 33.
If at any time it is ncecessary to remove the board 30 from the support frame 31, all that is necessary is to bend the longer leg 14 of each fastener towards the shorter leg 13 so as to release the abutment surface 24 from engagement with the rim of the aperture 33. This can be done manually and the printed circuit board 30 can then be drawn away from the support frame 31 without difficulty. Removal of the board 30 from the support frame 31 can thus be achieved easily and quickly without the need for any tool. Removal of the board 30 does not damage the legs 13 and 14 in any way so that the board can be remounted on the support frame when required.
Figure 5 illustrates a modification of the fastener 10 comprising a fastener 40 having a longer leg 41 formed with a shoulder 42 similar to the shoulder 24 of the fastener 10, a leading end 43 and a reversely directed arm 44. The arm 44 is formed with a shoulder 45 at its free end which is adapted to abut a shorter leg 46 of the fastener when the longer arm 41 is bent towards the shorter arm, thereby preventing overstressing of the longer arm 41. In all other respects the fastener 40 is similar to the fastener 10 and is used in the same manner.
Figure 6 illustrates a further modification of the fastener 10 comprising a fastener 50 which is similar to the fastener 10 except that the stud 12 of the fastener 10 has been replaced by two legs 51 and 52 which are similar in every respect to the legs 13 and 14 respectively of the fastener 10.
The provision of the legs 51 and 52 in place of the stud 12 enables the fastener 50 to be readily removable from the aperture 32 in the support frame 31 by bending the longer leg 52 towards the shorter leg 51 so as to release the abutment surface on the longer leg 52 from engagement with the rim of the aperture 32.
As with the fastener 10, this disengagement can be done manually and the fastener 50 can then be quickly and easily removed from the support frame 31.
It will be seen that we have provided a secure mounting for an apertured panel on a support frame which enables the apertured panel to be quickly and easily removed and remounted whenever required.
WHAT WE CLAIM IS 1. A fastener for mounting an apertured member on a support, the fastener comprising a base, means on one side of the base for mounting the fastener on a support and projecting from the opposite side of the base, two legs which are spaced from one another and which extend generally in parallel away from

  1. **WARNING** start of CLMS field may overlap end of DESC **.
    10 comprises a base 11, a stud 12 and two lets 13 and 14.
    The base 11 comprises a bowed plate 15 and a spacing member 16 which projects from one side of the plate 15. The spacing member 16 is cruciform in cross-section and serves only to space the legs 13 and 14 from the plate 15.
    The stud 12 projects from the concave side of the plate 15, that is the opposite side of the plate 15 to the spacing member 16. The stud 12 comprises a central stem 17 and two flexible wings 18 and 19 which are joined to the nose of the stem and which extend from the nose of the stem rearwardly towards the plate 15.
    The wings 18 and 19 are formed with abutment surfaces 20 and 21 respectively which face the concave surface of the plate 15.
    The legs 13 and 14 project from the end of the spacing member 16 remote from the plate 15. The legs 13 and 14 are spaced apart but extend generally in parallel away from the spacing member 16. The leg 13 is substantially shorter than the leg 14 and has an inclined leading face 22 which assists in leading the legs into an aperture. The longer leg 14 has a shoulder 23 which forms an abutment surface 24 which is spaced from but faces the spacing member 16. The leg 14 is tapered from the shoulder 23 towards its leading end 25.
    The fastener 10 is designed to mount a printed circuit board 30 on a support frame 31 as shown in Figure 4. The support frame 31 is formed with a plurality of circular apertures 32 appropriately positioned in the support frame. A fastener 10 is mounted in each of the apertures 32 by inserting the stud into the aperture. The diameter of the aperture 32 is such that the wings 18 and 19 of the stud 12 are flexed inwardly and then sanp outwardly so that the abutment surfaces 20 and 21 locate behind the support frame 31 and locate the fastener permanently on the support frame 31. The plate 15 is flattened slightly against the support frame 31 to ensure a firm and rattle-free mounting of the fastener on the support frame.
    The printed circuit board 30 is formed with a plurality of apertures 33 which correspond to the apertures 32 in the support frame 31.
    In order to attach the printed circuit board 30 to the support frame, the board 30 is brought up to the support frame so that the legs 13 and 14 of each fastener are located through an aperture 33 in the board 30. The inclined face 22 of the leg 13 provides a lead-in to the aperture 33. As the legs enter the aperture 33, the longer leg 14 is bent towards the shorter leg 13 until the shoulder 23 snaps through the aperture. The abutment surface 24 then secures the board 30 against the spacing member 16 of the fastener to securely mount the board on the support frame 31. The shorter leg 13 is so positioned that it engages the oppcsite side of the aperture 33 so as to locate the legs 13 and 14 correctly and ensure that the abutment surface 24 of the longer leg 14 is urged into tight enggement against the rim of the aperture 33.
    If at any time it is ncecessary to remove the board 30 from the support frame 31, all that is necessary is to bend the longer leg 14 of each fastener towards the shorter leg 13 so as to release the abutment surface 24 from engagement with the rim of the aperture 33. This can be done manually and the printed circuit board 30 can then be drawn away from the support frame 31 without difficulty. Removal of the board 30 from the support frame 31 can thus be achieved easily and quickly without the need for any tool. Removal of the board 30 does not damage the legs 13 and 14 in any way so that the board can be remounted on the support frame when required.
    Figure 5 illustrates a modification of the fastener 10 comprising a fastener 40 having a longer leg 41 formed with a shoulder 42 similar to the shoulder 24 of the fastener 10, a leading end 43 and a reversely directed arm 44. The arm 44 is formed with a shoulder 45 at its free end which is adapted to abut a shorter leg 46 of the fastener when the longer arm 41 is bent towards the shorter arm, thereby preventing overstressing of the longer arm 41. In all other respects the fastener 40 is similar to the fastener 10 and is used in the same manner.
    Figure 6 illustrates a further modification of the fastener 10 comprising a fastener 50 which is similar to the fastener 10 except that the stud 12 of the fastener 10 has been replaced by two legs 51 and 52 which are similar in every respect to the legs 13 and 14 respectively of the fastener 10.
    The provision of the legs 51 and 52 in place of the stud 12 enables the fastener 50 to be readily removable from the aperture 32 in the support frame 31 by bending the longer leg 52 towards the shorter leg 51 so as to release the abutment surface on the longer leg 52 from engagement with the rim of the aperture 32.
    As with the fastener 10, this disengagement can be done manually and the fastener 50 can then be quickly and easily removed from the support frame 31.
    It will be seen that we have provided a secure mounting for an apertured panel on a support frame which enables the apertured panel to be quickly and easily removed and remounted whenever required.
