Definitions
- the present invention concerns an adjustable-length push-button actuator for actuating an electrical contact or the like.
- Such an actuator according to the preamble of claim 1 is described for example in EP-A-0349367.
- these devices are not suitable for applications in which the push-button actuator is not actuated by a closure panel but must pass through a protective panel to be actuated in different way, for example, manually.
- adjustable-length push-button actuator that is the subject of the present invention, as defined and characterised in general in Claim 1. It is of simple construction, reliable, accurate and sensitive, and is easily adapted to any type of installation.
- the push-button actuator shown in Figure 1 includes: a cylindrical rod-like element 10; an actuator element generally in the form of a sleeve 11 adapted to receive the rod 10 therein; coupling means formed by three resilient tongues 12 formed integrally with the sleeve 11 and extending in the direction of the axis thereof and a coupling element 14 which is part of the rod 10; and a guide member in the form of a bush 16 which is able to receive the sleeve 11 therein.
- Each of the resilient tongues 12 has a coupling tooth 13 which projects radially inwardly of the sleeve 11 and the coupling element 14 has annular V-section grooves 15.
- the tongues form resilient gripper means for compressively engaging one of the annular grooves 15 and coupling the rod 10 to the sleeve 11.
- the sleeve-like actuator element 11 also has two stop teeth 18 which project radially outwards and four integral appendages, or arms, 9 which extend axially and are provided with stop teeth 17.
- the outer diameter of the sleeve 11 is slightly less than that of the interior of the bush 16 so as to enable the sleeve to slide easily and axially in the bush, while the teeth 17 project beyond the internal perimeter of the bush 16 and, in this example, are shaped like saw teeth.
- the bush 16 has two lateral cavities, in this example formed as two apertures 19, which extend axially so as to constitute two seats with end abutments for the axial sliding of the teeth 18 of the sleeve 11, as well as an annular flange 20 and two projections 21.
- the rod 10 has a channel 22 which extends along its entire length apart from a short portion 23 close to one of its ends, and the sleeve 11 has an internal projection 7 for engaging the channel 22.
- the rod 10 also has annular notches 28 for fracture at predetermined positions, that is, for defining regions of weakness where the rod itself may easily be broken to allow its length to be adjusted roughly.
- the three parts described above may easily be formed from a suitable plastics material by known moulding techniques.
- the actuator element 11 is inserted in the bush 16 by force-fitting through the end with the flange 20, that is, downward as seen in the drawing, so as to cause the resilient deformation of the arms 9 and their subsequent return to their rest positions after the stop teeth 17 have passed beyond that edge of the bush 16 opposite that with the flange 20.
- the axial sliding of the actuator element 11 in the bush 16 is limited in one direction by the abutment of the stop teeth 17 with the lower edge (as seen in the drawing) of the bush 16 and, in the opposite direction, by the abutment of the teeth 18 with the inner ends of the apertures 19.
- the axial sliding between the two stops constitutes the actuation stroke of the push-button.
- the rod 10 is then inserted in the actuator element 11 through the end with the arms 9, that is, upward as seen in the drawing, so that the projection 7 engages the channel 22.
- the rod 10 is fixed against rotation and its axial sliding is limited in one direction by the contact of the projection 7 with the end of the channel adjacent the portion 23. This prevents. the accidental extraction of the rod 10.
- the working position of the rod 10 relative to the actuator element 11 is determined by the selection of one of the annular grooves 15 for compression engagement by the teeth 13 of the resilient tongues 12.
- the shape of the teeth 13 and of the annular grooves 15 is such that the rod may be located in the desired position by an axial pull or push thereon such as to overcome the gripping force of the resilient gripper constituted by the tongues 12 and the teeth 13.
- the length of the push-button actuator may thus be finely adjusted within a range of variation determined by the length of the coupling element 14.
- the flange 20 and the projections 21 of the bush 16 constitute fixing means for anchoring the push-button actuator to a wall or plate 24 of an external structure, for example, a container in which a switch to be actuated is fixed, as will be described below with reference to Figures 5 and 6.
- the plate 24 has a circular hole 25 with a slightly greater diameter than that of the bush 16 and two diametrically opposed notches 26 for allowing the projections 21 to pass through.
- the edge of the hole 25 is formed with two seats 27 for the projections 21. More particularly, two inclined faces 6 allow the fixing of the bush 16 to the plate 24 by virtue of the interference between the flange 20, the plate 24 and the projections 21. Coupling is therefore achieved by the insertion of the bush 16 through the hole 25 so that the flange 20 is brought into contact with the outer surface of the plate, and the rotation of the bush to bring the projections 21 into their respective seats 27.
- FIG. 5 An application of the push-button actuator described above is shown in Figures 5 and 6.
- This example relates to a push-button switch device for anti-theft installations and the like in which, as indicated at the start of this description, the removal of a panel causes the activation of alarm or signalling devices.
- a push-button switch 30 is mounted on a printed circuit board 31 upon which is cantilevered a leaf spring 32 shaped so that it has a curved operating portion 33 close to the switch control member 34.
- the printed circuit 31 and the container 35 together form a support structure for the switch and the push-button actuator.
- This latter, generally indicated 8 is mounted on a plate in the manner described in relation to Figure 1, the plate being fixed to the container 35 and indicated 24 as in Figure 1.
- the sleeve-like actuator element 11 is in contact with the free end of the spring 32 by means of the ends of its arms 9. More precisely, the arrangement and dimensions of the various parts are such that the spring 32 exerts an upward force, with reference to the drawings, which keeps the stop teeth 17 of the arms 9 in contact with the lower edge of the bush 16, as shown in Figure 5.
- the actuator element 11 moves axially against the action of the spring 32 until the stop teeth 11 contact the inner ends of the associated apertures 19. This movement causes the curved portion 33 of the spring 32 to act on the switch control member, causing it to switch, that is, to close or open the swith contacts depending on the constructional characteristics of the switch itself.
- stroke of the push-button switch actuator 8, indicated ādā in the drawing, is equal to or only slightly greater than the stroke of the control member of the switch 30.
- the length of the push-button actuator is adjustable according to the requirements of individual applications. More particularly, this length may be reduced by the breaking and removal of a portion bounded by a notch 28 to achieve a rough adjustment, and may then be further reduced or increased by a respective push or pull on the rod 10 to vary the position of engagement of the teeth 13 with the coupling element 14 for fine adjustment.
- This possibility of adjusting the push-button actuator according to the invention is particularly advantageous when it is wished to indicate the removal of a panel, for example, in an anti-theft installation, or when it is wished to de-activate an electrical panel when the front closure panel is removed.
- the push-button actuator 8 is mounted in position on the support structure of the switch 30 to be actuated, as shown in Figure 5.
- the rod 10 is shortened, if necessary, by the removal of a portion bounded by a peripheral notch 28 such that its length, with the teeth 13 of the resilient tongues 12 engaged with an annular groove 15 in the coupling element 14 close to the lower end of the rod 10, with reference to the drawing, is such that the upper end of the rod 10 is above the level of the upper edge of the container 35.
- the closure panel 36 of the container 35 is fitted for the first time, its inner surface contacts the upper end of the rod 10 of the push-button actuator, exerting an axially-downward force on the rod itself.
- the actuator element 11 first presses the free end of the spring 32 downward and hence actuates the switch 30 through the pressure of the curved operating portion 33 of the spring on the switch control member, and then, when the stroke of the push-button actuator is complete, the resilient tongues 12 open, allowing the coupling element 14 to move downward, with reference to the drawing, until the force exerted by the panel 36 on the push-button actuator 8 is equal to the force exerted by the spring 32.
- the teeth 13 of the tongues 12 are engaged with an annular groove 15 and define a new, stable coupling position of the rod 10 with the actuator 11 which corresponds to the particular installation conditions.
- the spring 32 has an opening 37 which allows the end part of the rod 10 to pass through.
- the length of the push-button actuator according to the invention is adjusted automatically which therefore makes it extremely useful in all applications in which it is neither possible nor convenient to determine the exact position of the switch beforehand.
- a further advantage of the push-button actuator according to the invention is that it may easily be fitted to any support structure as long as it has a wall or plate with an aperture adapted to couple with the bush 16.
- the means for fixing the bush 16 to the plate may differ from those illustrated and described, for example, a different type of housing coupling, or a screw coupling may be envisaged.
- the rod may be provided with resilient tongues with associated teeth
- the coupling element with the annular grooves may be formed as an integral extension of the actuator element.
- the resilient tongues may be disposed so as to form a resilient expansion grip rather than a compression grip so as to engage annular grooves in an inner surface of a bush which replaces the coupling element 14.
- the positioning of the tongues and the coupling element may be interchanged.
- further variants may provide a thread or a series of notches in correspondence with the engagement teeth of the resilient tongues.
Abstract
Description
- The present invention concerns an adjustable-length push-button actuator for actuating an electrical contact or the like. Such an actuator according to the preamble of claim 1 is described for example in EP-A-0349367.
- In many applications it is necessary for a push-button electrical switch, or the like, to be located in such a position that it can be actuated from a distance which is measured precisely from the surface on which the switch itself is mounted.
- For example, in anti-theft devices and burglar alarms, the removal or opening of a protective panel must cause alarm or signalling devices to be activated by the opening or closure of an electrical contact, or the actuation of an equivalent device. To this end, mechanical push-button switch devices are used which are mounted in a predetermined position relative to the panel and are actuated by a change in the position of the panel. When these devices are mounted on a printed circuit board or equivalent support together with other electronic components, the printed circuit must be installed very accurately in a predetermined position relative to the protective closure panel. This is neither easy nor practical.
- To overcome this limitation, it has been proposed to use push-button switch actuators in which a rod acts on the switch through a helical compression spring. Pressure exerted on the head of the spring actuates the switch.
- These devices are inaccurate and unreliable: in fact, the force transmitted to the switch by the spring varies considerably according to the installation conditions, and may even be so great as to deform or break the switch or its support.
- In addition, these devices are not suitable for applications in which the push-button actuator is not actuated by a closure panel but must pass through a protective panel to be actuated in different way, for example, manually.
- These disadvantages are overcome by the adjustable-length push-button actuator that is the subject of the present invention, as defined and characterised in general in Claim 1. It is of simple construction, reliable, accurate and sensitive, and is easily adapted to any type of installation.
- The characteristics and advantages of the invention will become clearer from the following description of a preferred embodiment given by way of non-limitative example and with reference to the accompanying drawings, in which:
- Figure 1 is a perspective view of a preferred embodiment of an adjustable-length push-button actuator according to the present invention with the parts separated;
- Figures 2, 3 and 4 are transverse sections of details of the push-button actuator of Figure 1; and
- Figures 5 and 6 show, in longitudinal section, a particular use of the push-button actuator of Figure 1 in two different operative positions.
-
- The push-button actuator shown in Figure 1 includes: a cylindrical rod-
like element 10; an actuator element generally in the form of a sleeve 11 adapted to receive therod 10 therein; coupling means formed by threeresilient tongues 12 formed integrally with the sleeve 11 and extending in the direction of the axis thereof and acoupling element 14 which is part of therod 10; and a guide member in the form of abush 16 which is able to receive the sleeve 11 therein. - Each of the
resilient tongues 12 has acoupling tooth 13 which projects radially inwardly of the sleeve 11 and thecoupling element 14 has annular V-section grooves 15. The tongues form resilient gripper means for compressively engaging one of theannular grooves 15 and coupling therod 10 to the sleeve 11. - The sleeve-like actuator element 11 also has two
stop teeth 18 which project radially outwards and four integral appendages, or arms, 9 which extend axially and are provided withstop teeth 17. The outer diameter of the sleeve 11 is slightly less than that of the interior of thebush 16 so as to enable the sleeve to slide easily and axially in the bush, while theteeth 17 project beyond the internal perimeter of thebush 16 and, in this example, are shaped like saw teeth. - The
bush 16 has two lateral cavities, in this example formed as twoapertures 19, which extend axially so as to constitute two seats with end abutments for the axial sliding of theteeth 18 of the sleeve 11, as well as anannular flange 20 and twoprojections 21. - In addition, the
rod 10 has achannel 22 which extends along its entire length apart from ashort portion 23 close to one of its ends, and the sleeve 11 has an internal projection 7 for engaging thechannel 22. - The
rod 10 also hasannular notches 28 for fracture at predetermined positions, that is, for defining regions of weakness where the rod itself may easily be broken to allow its length to be adjusted roughly. - The three parts described above may easily be formed from a suitable plastics material by known moulding techniques.
- The actuator element 11 is inserted in the
bush 16 by force-fitting through the end with theflange 20, that is, downward as seen in the drawing, so as to cause the resilient deformation of thearms 9 and their subsequent return to their rest positions after thestop teeth 17 have passed beyond that edge of thebush 16 opposite that with theflange 20. The axial sliding of the actuator element 11 in thebush 16 is limited in one direction by the abutment of thestop teeth 17 with the lower edge (as seen in the drawing) of thebush 16 and, in the opposite direction, by the abutment of theteeth 18 with the inner ends of theapertures 19. The axial sliding between the two stops constitutes the actuation stroke of the push-button. - The
rod 10 is then inserted in the actuator element 11 through the end with thearms 9, that is, upward as seen in the drawing, so that the projection 7 engages thechannel 22. In this way therod 10 is fixed against rotation and its axial sliding is limited in one direction by the contact of the projection 7 with the end of the channel adjacent theportion 23. This prevents. the accidental extraction of therod 10. The working position of therod 10 relative to the actuator element 11 is determined by the selection of one of theannular grooves 15 for compression engagement by theteeth 13 of theresilient tongues 12. - It should be noted that the shape of the
teeth 13 and of theannular grooves 15 is such that the rod may be located in the desired position by an axial pull or push thereon such as to overcome the gripping force of the resilient gripper constituted by thetongues 12 and theteeth 13. The length of the push-button actuator may thus be finely adjusted within a range of variation determined by the length of thecoupling element 14. - The
flange 20 and theprojections 21 of thebush 16 constitute fixing means for anchoring the push-button actuator to a wall orplate 24 of an external structure, for example, a container in which a switch to be actuated is fixed, as will be described below with reference to Figures 5 and 6. To this end, theplate 24 has acircular hole 25 with a slightly greater diameter than that of thebush 16 and two diametrically opposednotches 26 for allowing theprojections 21 to pass through. The edge of thehole 25 is formed with twoseats 27 for theprojections 21. More particularly, two inclined faces 6 allow the fixing of thebush 16 to theplate 24 by virtue of the interference between theflange 20, theplate 24 and theprojections 21. Coupling is therefore achieved by the insertion of thebush 16 through thehole 25 so that theflange 20 is brought into contact with the outer surface of the plate, and the rotation of the bush to bring theprojections 21 into theirrespective seats 27. - An application of the push-button actuator described above is shown in Figures 5 and 6. This example relates to a push-button switch device for anti-theft installations and the like in which, as indicated at the start of this description, the removal of a panel causes the activation of alarm or signalling devices.
- A push-
button switch 30 is mounted on a printedcircuit board 31 upon which is cantilevered aleaf spring 32 shaped so that it has acurved operating portion 33 close to the switch control member 34. - The
board 31, in its turn, is mounted in acontainer 35 only part of which is shown in the drawings. The printedcircuit 31 and thecontainer 35 together form a support structure for the switch and the push-button actuator. This latter, generally indicated 8, is mounted on a plate in the manner described in relation to Figure 1, the plate being fixed to thecontainer 35 and indicated 24 as in Figure 1. The sleeve-like actuator element 11 is in contact with the free end of thespring 32 by means of the ends of itsarms 9. More precisely, the arrangement and dimensions of the various parts are such that thespring 32 exerts an upward force, with reference to the drawings, which keeps thestop teeth 17 of thearms 9 in contact with the lower edge of thebush 16, as shown in Figure 5. When the push-button actuator 8 is pressed, the actuator element 11 moves axially against the action of thespring 32 until the stop teeth 11 contact the inner ends of the associatedapertures 19. This movement causes thecurved portion 33 of thespring 32 to act on the switch control member, causing it to switch, that is, to close or open the swith contacts depending on the constructional characteristics of the switch itself. - It should be noted that the stroke of the push-
button switch actuator 8, indicated "d" in the drawing, is equal to or only slightly greater than the stroke of the control member of theswitch 30. - The length of the push-button actuator, as has been said, is adjustable according to the requirements of individual applications. More particularly, this length may be reduced by the breaking and removal of a portion bounded by a
notch 28 to achieve a rough adjustment, and may then be further reduced or increased by a respective push or pull on therod 10 to vary the position of engagement of theteeth 13 with thecoupling element 14 for fine adjustment. - This possibility of adjusting the push-button actuator according to the invention is particularly advantageous when it is wished to indicate the removal of a panel, for example, in an anti-theft installation, or when it is wished to de-activate an electrical panel when the front closure panel is removed. In these applications, the push-
button actuator 8 is mounted in position on the support structure of theswitch 30 to be actuated, as shown in Figure 5. Before or after the mounting, therod 10 is shortened, if necessary, by the removal of a portion bounded by aperipheral notch 28 such that its length, with theteeth 13 of theresilient tongues 12 engaged with anannular groove 15 in thecoupling element 14 close to the lower end of therod 10, with reference to the drawing, is such that the upper end of therod 10 is above the level of the upper edge of thecontainer 35. As shown in Figure 6, when theclosure panel 36 of thecontainer 35 is fitted for the first time, its inner surface contacts the upper end of therod 10 of the push-button actuator, exerting an axially-downward force on the rod itself. As a result of this force, the actuator element 11 first presses the free end of thespring 32 downward and hence actuates theswitch 30 through the pressure of thecurved operating portion 33 of the spring on the switch control member, and then, when the stroke of the push-button actuator is complete, theresilient tongues 12 open, allowing thecoupling element 14 to move downward, with reference to the drawing, until the force exerted by thepanel 36 on the push-button actuator 8 is equal to the force exerted by thespring 32. At this point theteeth 13 of thetongues 12 are engaged with anannular groove 15 and define a new, stable coupling position of therod 10 with the actuator 11 which corresponds to the particular installation conditions. - It should be noted that the
spring 32 has an opening 37 which allows the end part of therod 10 to pass through. - If the
panel 36 is removed, thespring 32 returns to the rest position shown in Figure 5, releasing the control member of theswitch 30 and hence switching the latter and activating an associated alarm. - When the closure panel is subsequently reapplied, this causes a stroke of the rod exactly sufficient to operate the switch.
- It should be noted that, in this application, the length of the push-button actuator according to the invention is adjusted automatically which therefore makes it extremely useful in all applications in which it is neither possible nor convenient to determine the exact position of the switch beforehand.
- A further advantage of the push-button actuator according to the invention is that it may easily be fitted to any support structure as long as it has a wall or plate with an aperture adapted to couple with the
bush 16. Naturally, the means for fixing thebush 16 to the plate may differ from those illustrated and described, for example, a different type of housing coupling, or a screw coupling may be envisaged. - Although only one embodiment of the invention has been illustrated and described, it is clear that numerous variants are possible within the ambit of the same inventive concept. For example, there may be two or four
resilient tongues 12 rather than three, the mutual positioning of theresilient tongues 12 and thecoupling element 14 may be changed, that is, the rod may be provided with resilient tongues with associated teeth, and the coupling element with the annular grooves may be formed as an integral extension of the actuator element. Furthermore the resilient tongues may be disposed so as to form a resilient expansion grip rather than a compression grip so as to engage annular grooves in an inner surface of a bush which replaces thecoupling element 14. In this case also, the positioning of the tongues and the coupling element may be interchanged. Instead of the annular grooves, further variants may provide a thread or a series of notches in correspondence with the engagement teeth of the resilient tongues.
