Abstract

A connector for connecting two furniture panels (15, 17) together, the connector comprising a first pin member (10) affixable to the first panel (15) and insertable into a blind bore (18) formed in the second panel (17) and a second pin member (20) insertable into a second blind bore (19) formed in the second panel (17). Each pin (10, 20) is grooved around its curved surface and the grooved portion (21) of the second pin (20) is eccentrically disposed about the longitudinal axis of the pin (20). The dimensioning and location of the pins (10, 20), their grooved portions (11, 21)and the intersecting blind bores (18, 19) are such that simple rotation of the second pin (20) causes the pin (20) to engage the pin (10) so as to produce a locking connection between the two panels (15, 17). <IMAGE>

Description

SPECIFICATION Panel connector The present invention relates to a detachable connection for connecting two panels, preferably furniture panels, together, the panels extending at right angles to one another.
A connection is known in which a detachable connection for connecting two furniture panels extending substantially at right angles to one another, wherein an attachment pin having a head portion is fixedly mounted in the first panel and a clamping pin is rotatably mounted in the second panel, the clamping pin having a recess formed in its curved surface to act as a clamping surface, the recess co-operating with the head of the attachment pin, the clamping pin being rotatable and being capable, in use, of longitudinally displacing the attachment pin so as to clamp the two panels together, the axis of rotation of the clamping pin being disposed vertically and being laterally offset relative to the longitudinal axis of the attachment pin, wherein the attachment pin and the clamping pin each have substantially the same diameter and are guided and rotatably mounted respectively in blind bores formed in the second panel.
In such a known device, the clamping pin and the attachment pin are, respectively, mounted and guided in a bearing element which is inserted into a blind bore formed in the second panel. The correct locations of the attachment pin and of the clamping pin are maintained by so doing. The clamping face of the clamping pin is formed by a laterally extending recess in the external surface of the pin. The longitudinal axis of the recess extends at right angles to the longitudinal axis of the clamping pin. In such case, the cross-section of the recess may be toroidal. The head portion of the attachment pin is separated from the main body portion of the pin by a cylindrical portion which is of reduced diameter compared with the body portion and extends into the inclined connecting surfaces of the attachment head.The clamping pin, which is rotatably mounted and is laterally offset relative to the longitudinal axis of the attachment pin, is rotatable so that the lateral recess formed in its surface allows the head of the attachment pin to be introduced therein. If the clamping pin is then rotated, the clamping surface of the clamping pin engages behind the head of the attachment pin and displaces the attachment pin longitudinally. Thus, the two panels are clamped together and interconnected.
In such a connector, a relatively large blind bore must be formed in the second panel so that the bearing element may be inserted therein. The end of this bearing element always remains visible on the surface of the second panel. In addition, a further bore extending from the front end of the second panel often has to be provided for the attachment pin. Furthermore, only a limited clamping force can be produced by such a connector, because the two pins are only adjacent to each other in a punctiform or linear manner. A further disadvantage is that the attachment pin usually has some clearance in the bearing element and is not sufficiently accurately guided.
The present invention seeks to provide a detachable connector generally of the above-mentioned type for connecting two panels, generally furniture panels, which lie at right angles one to the other, but in which the number of components is reduced and a substantially greater clamping force may be achieved between the two panels. Thus, the two panels are clamped together and interconnected.
In such a connector, a relatively large blind bore must be formed in the second panel so that the bearing element may be inserted therein. The end of this bearing element always remains visible on the surface of the second panel. In addition, a further bore extending from tY(e front end of the second panel often has to be provided for the attachment pin. Furthermore, only a limited clamping force can be produced by such a connector, because the two pins are only adjacent to each other in a punctiform or linear manner. A further disadvantage is that the attachment pin usually has some clearance in the bearing element and is not sufficiently accurately guided.
The present invention seeks to provide a detachable connector generally of the above-mentioned type for connecting two panels, generally furniture panels, which lie at right angles one to the other, but in which the number of components is reduced and a substantially greater clamping force may be achieved between the two panels.
According to the present invention, there is provided a detachable connection for connecting two furniture panels extending substantially at right angles to one another, wherein an attachement pin having a head portion is fixedly mounted in the first panel and a clamping pin is rotatably mounted in the second panel, the clamping pin having a recess formed in its curved surface to act as a clamping surface, the recess co-operating with the head of the attachment pin, the clamping pin being rotatable and being capable, in use, of longitudinally displacing the attachment pin so as to clamp the two panels together, the axis of rotation of the clamping pin being disposed vertically and being laterally offset relative to the longitudinal axis of the attachment pin, wherein the attachment pin and the clamping pin each have substantially the same diameter and are guided and rotatably mounted respectively in blind bores formed in the second panel, the head portion of the attachment pin being separated from the main body of the attachment pin by a grooved portion extending around the pin, the groove being circular in cross-section, the radius of the groove being substantially equal to the radius of the attachment pin, the surface of the groove being regarded as a plurality of infinitesimally thin strips, each strip forming an arc of a different circle, the centres of such circles lying on the circumference of an imaginary circle located externally of the surface of the attachment pin but being concentric with the longitudinal axis of the attachment pin, the clamping face of the clamping pin being formed as a grooved portion, which is circular in cross-section, the radius of the groove being substantially equal to the radius of the clamping pin, the surface of the groove in the clamping ring also being regarded as a plurality of infinitesimally thin strips, each strip forming an arc of a different circle, the centres of such circles lying on the circumference of an imaginary circle which is eccentrically disposed relative to the longitudinal axis of the clampinvg pin, the eccentricity corres ponds to substantially half the radius of the clamping pin, the blind bores being so formed in the second panel that, upon insertion of the two pins into their blind bores, the longitudinal axis of the clamping pin is offset relative to the central plane of the groove in the attachment pin by a predetermined amount, such offsetting being towards the head portion of the attachment pin and the offsetting distance being less than the radius of the clamping pin.
Such a design of the attachment and clamping pins means that there is always a large area of connection between the grooves of the attachment pin and the clamping pin. Because the pins are directly mounted in blind bores formed in the second panel, a separate bearing element is not necessary. Furthermore, in a preferred arrangement, only the end face of the clamping pin is visible and this may be so designed as to be substantially smaller than the visible faces of known bearing elements. Since the attachment pin and the clamping pin may be clamped over a large area within the blind bores, a clearance-free connection is achieved which is self-locking in the clamping position. The clamping position is therefore securely maintained without the necessity of additional expenditure on further locking devices.
Preferably, the diameter of the imaginary circle connecting the centres of the circles of which the strips from arcs of the groove in the attachment pin is substantially three times the radius of the attachment pin.
Similarly, it is preferable if the diameter of the imaginary circle connecting the centres of the circles of which the strips in the groove in the clamping pin form arcs is substantially three times the radius of the clamping pin.
A portion of the attachment pin thus still remains in the central plane of the groove of the attachment pin and this remaining portion has a diameter which corresponds substantially to the radius of the pin.
So that the portion of the clamping pin remaining in the central plane of the clamping groove can have substantially the same strength it is desirable if the lateral offsetting of the longitudinal axis of the clamping pin relative to the longitudinal axis of the attachment pin corresponds substantially to the radius of the attachment pin.
In order to achieve as long a clamping path as possible for the attachment pin, it is advantageous if the longitudinal axis of the clamping pin is offset towards the head end of the attachment pin, by an amount smaller than the radius of the clamping pin and corresponding substantially to half the radius of the clamping pin.
The specific engagement of the clamping groove of the clamping pin in the groove of the attachment pin may be achieved if the depth of the blind bore for the clamping pin and the location of the clamping groove on the clamping pin are selected such that the clamping groove is aligned with the blind bore for the attachment pin.
In a desirable embodiment, the desired location of the groove in the attachment pin when it is inserted into the blind bore relative to the position of the clamping pin is achieved if the attachment pin is - provided, at one of its ends, with attachement means for connection to the first panel, a stop shoulder being provided in the end region of the pin provided with the attachment means, the location of the groove in the attachment pin being selected such that the central plane of the groove is offset by a predetermined amount relative to the central axis of the blind bore for the clamping pin in a direction towards the attachment means of the attachment.
The introduction of the attachment pin into the blind bore in the second panel may be simplified if the head portion of the attachment pin is radiused at its free end.
To enable the attachment pin to be adjusted in the blind bore over the entire clamping path, it is further preferred if the depth of the blind bore for the attachment pin is greater than the distance from the stop shoulder to the end face of the head portion of the attachment pin added to the maximum clamping distance which corresponds substantially to the radius of the clamping pin.
In a further desirable embodiment the end face of the clamping pin lies flush with the underside of the second panel when the connector is in use, the end face of the clamping pin being provided with an adjustment slot.
The invention will be further described, by way of example, with reference to the accompanying drawings, in which: Figure lisa sectional view taken through a detachable connection which connects two panels extending at right angles to one another, Figure 2 is an external view of the connection of Figure 1 viewed from the underside of the panels, Figure 3 is a view, on an enlarged scale relative to Figures 1 and 2, of a detail of part of the connection in a first position, and Figure 4 is a view similar to Figure 3, but showing the parts of the connection in a second position.
In Figures 1 and 2, there is shown two panels 15 and 17 which are connected together so as to extend at right angles to one another. To achieve such a connection, only a single connector is required. The connector comprises an attachment pin 10 and a clamping pin 20. The pins 10 and 20 have substantally the same diameter. The attachment pin 10 has a screw-threaded end portion which engages in a blind bore 16 formed in the first panel 15. This end portion may, alternatively, be a drive-in portion provided with a retaining barb or barbs. The end portion 14 is connected to a shoulder portion 13 of the pin 10. The attachment pin 10 also has a head portion 12 which is separated from the main body of the pin by a circular groove portion 11, which is arcuate and extends around the curved surface of the pin. The free end edge of the head portion 12 is cross-section and extends around the curved surface of the pin. The free end edge of the head portion 12 is radiused. A blind bore 18 is formed substantially centrally in the front face in the second panel 17. The front face is the face which abuts, in use, the first panel 15. The diameter of the base 18 corresponds substantially to the diameter of the attachment pin 10 but the depth thereof is greater than the length of the attachment pin 10 from the shoulder portion 13 to the free end face of the head portion 12, at least for the maximum clamping distance.
As can be seen in Figure 2, a blind bore 19 is formed in the underside of the second panel 17, the diameter and depth of which correspond to the diameter and the axial length respectively of the clamping pin 20. One end face of the clamping pin 20 has an adjustment slot 22 formed therein and, in use, lies flush with the underside of the second panel 17.
The blind bore 19 for the clamping pin 20 extends substantially at right angels to the longitudinal axis 24 of the attachment pin 10 and to that of the blind bore 18. However, the central axis of the blind bore 19 is also displaced laterally relative to the longitudinal axis 24 of the blind bore 18, so that the longitudinal axis 26 of the clamping pin 20 is offset from the longitudinal axis 24 of the attachment pin 10 by a distance a shown in Figure 3. The distance a is at leat equal to the radius of the attachment pin 10 and the clamping pin 20, plus a small tolerance amount of 0.5 to 1 .Omm, since the blind bores 18 and 19 can only be formed in the second panel 17 with such corresponding tolerance.
The grooved portion 11 separating the head portion 12 from the main body of the attachment pin 10 is arcuate in cross-section and the groove has a radius which corresponds to the radius of the attachment pin 10. The base of the groove 11 is located in a central plane 25. The groove 11 therefore extends concentrically around the longitudinal axis 24 of the pin 10. The grooved portion 11 extends around the pin through 360" and may therefore be regarded as a series of infinitesimally thin strips, each forming an arc of a different circle centered in the plane 25.The centres of these circles define a further imaginary circle having a diameter which is substantially three times the radius ofthe main body of the pin 10, so that the minimum diameter of the grooved portion 11 is substantially equal to the radius of the main body portion of the pin 10.
The clamping pin 20 is also provided with a circular grooved portion 21 which is circular in cross-section and acts as a clamp. The radius of the groove 21 corresponds to the radius of the clamping pin 20. The imaginary circle defined by the centres of the circles of which infinitesimally thin strips of the grooved portion 21 from arcs has a diameter which corresponds substantially to three times the radius of the clamping pin 20. However, the centre of the clamping groove portion 21 is offset by a predetermined amount c relative to the longitudinal axis 26 of the clamping pin 20. This eccentricity corresponds substantially to half the radius of the clamping pin 20, so that the portion of minimum diameter of the clamping groove portion 21 touches the longitudinal axis 26 and also the external surface ot the clamping pin 20, as shown in Figures 3 and 4.
The eccentricity also corresponds to the distance between the longitudinal axis 26 of the clamping pin 20 and the central axis of the clamping groove 21.
In Figure 3, the attachment pin 10 has been introduced into the blind bore 18, past the clamping pin 20. The base of the clamping groove 21 of the clamping pin 20 faces the attachment pin 10 and, accordingly, the groove does not hinder the insertion of the attachment pin 10. The bores 18 and 19 are, however, offset to one another, although still perpendicular to one another, by a pre-determined amount b so that the longitudinal axis 26 of the pin 20 is offset relative to the central plane 25 of the groove 11 in the attachment pin 10 in a direction towards the head end 12 of the attachment pin 10.
This amount b is preferably selected so as to correspond substantially to half the radius of the clamping pin 20. However, it may be selected slightly larger than this but must be less than the radius of the clamping pin 20.
As can be seen in Figure 4, the clamping pin 20 may be rotated in the direction of the arrow 28, so that the cylindrical grooved clamping portion 21 thereof is rotated into the grooved portion 11 of the attachment pin 10. If the cylindrical grooved portion 21 is in abutment with the grooved portion 11 of the attachment pin 10 (as shown in Figure 4), further rotation of the clamping pin 20 causes the attachment pin 10 to be axially displaced in the direction of the arrow 29. The two panels 15 and 17 are thus drawn towards one another and clamped together.
The attachment pin 10 is pressed against the wall of the blind bore 18 and the clamping pin 20 is pressed againstthewall ofthe blind bore 19. This ensures that both are fixed in a clearance-free manner relative to one another. If the predetermined amount b is selected to be equal to the radius of the clamping pin 20, then the attachment pin 10 could, in theory be maximally axially adjusted by an amount corresponding to the radius of the clamping pin 20.
However, the actual clamping distance is slightly shorter because, for tolerance reasons, the distance a is slightly longer than the radius of the attachment pin 10 and because the distance b is smaller than the radius of the clamping pin 20, for example, half such radius. When such a distance b is selected, the maximum adjustment distance of the clamping groove 21 in the clamping pin 20 is not utilised.
Accordingly, the locking between the clamping groove 21 and the attachment groove 11 occurs before the end position is reached. The set position of rotation of the clamping pin 20 cannot, therefore, be released automatically, so that the clamping position of the connector is securely maintained.
Because of the blind bores 18 and 19 formed in the second panel 17 and because of the provision of the grooves 11 and 21 in the attachment pin 10 and the clamping pin 20 respectively, a releasable connection is produced between the panels 15 and 17 which lie at right angles to one another. Such connection permits a high clamping force to be applied and a clearance-free fit between the attachment pin 10 and the clamping pin 20 can be achieved. Thus in production, it is merely necessary to ensure the correct alignment of the blind bores 18 and 19 and the correct location of the grooves 11 and 21 on the attachment and clamping pins 10 and 20 respective ly. By means of the two simple fastening members, that is to say, the attachment pin 10 and the clamping pin 20, not only is a detachable connection between two panels 15 and 17 extending at right angles to one another achieved, which connection is inexpensive and permits the use of high clamping forces, but also only the relatively small front end face of the clamping pin 20, with its adjusting slot 22, is visible on the underside of the second panel 17.
