SPIDER MOUNTING
The present invention relates to a mounting system adapted for mounting a radiant heating element bodv :vith spring-loading against the underside of a vitreous ceramic top of a heating or cooking appliance such as a warming plate. hot plate.
kitchen stove or cooking range, said spring-loading being provided by a plurality of resilient support brackets extending radially upwards and outwards from a support base from underneath the heating element body into engagement with the marginal reEion of the latter. the support base being adapted for being mounted in axed. rigid relationship to the bodv of the appliance.
DE 29I5~29 AI discloses a mounting system for mounting a radiant heating element bodv vyith spring-loading against the underside of a vitreous ceramic top of a cooking appliance. The spring-~oadine is provided by a single conca~-elv upwardiv bent spring metal strip, forming an integrated pair of resilient support bracket arms extending radiallv upwards. in opposite directions from a central point of a support base, in hinged relationship thereto. The two arms terminate in :~pwardIy directed claws, frictionally engaging the marginal regions of the heating element body, and pressing the element body with spring action against the underside of :he vitreous ceramic top.
This assembly is inserted from below into a tray F through a sui~ciently large hole in the bottom of the tray which near the top forms a shoulder onto which the vitreous ceramic top is bonded in sealing relationship by means of a heat resistant adhesive.
After insertion of the element body and spring bracket means. the support base is fixed to the bottom of the trav so as to close the said hole in the tray and position the assembly in relation to the vitreous ceramic top.
Previously when assembling such cooking appliances in a conventional manner, the procedure was that components which are to be accommodated inside the housing i body, such as, for example, in particular support means for heating elements and the heating element itself were sequentially installed in the housing body from the top.
After their installation and the corresponding connecting of electrical cables, the upper cover plate, respectively the cooking plate, was placed~nto~tlie housing bo"$y The replacement of individual parts in electzicai cooking appliances manufactured according to that comrentional construction was expensive and in part no even possible. Whereas the construction according to the aforesaid DE X915529 A 1 permits installing the element body with wing connected thereto from the underside of the already ftted vitreous ceramic top, the method of assembling is nevertheless awkward because of the loose interrelationship of the mourning means until the base plate has finally been faced in place. However, even then the anal assembly is relatively unstable, and may lead to lateral displacement of the element body in relation to the vitreous ceramic top, e.U. during transportation or even during mere shifting of the appliance.
A further disadvantase of the conventional manner of manufacture ~f electrical cookins appliances of the aforesaid type resides in the differem sizes or diameters of 1 ~ heating elements invariably necessitated individual support means adapted to match the size of the heating element. As a result, it is not possible to employ uniform support means or installation parts for each particular cooking appliance type, more particularly in view of the different diameters of the heating element ar elements. The aforesaid drawbacks inherent in conventional electrical cooking appliances represent =0 considerable burdens both technically as well as economically.
A need exists to eliminate or mitigate these disadvantages which are inherent in conventional electrical cooking appliances or which have in the past arisen during the installation of electrical cooking appliances of the aforesaid type. in particular of table 25 model cooking appliances having vitreous ceramic cooking plates. In this context, it is a particular object of the invention to provide a mounting assembly for heating elements of an electrical cooking appliance, in particular a table model cooking appliance having a vitreous ceramic cooking plate and including a housing body by means of which it is possible to avoid or mitigate the aforesaid disadvantages.

Fig. ~ represents inside elevation a detail of an alternative embodiment of a mounting system in accordance «ith the invention: and Fig. 6 represents a view similar to Fig. = of yet a further embodiment of the mounting .0 system.
The table model cooking plate diagrammatically illustrated in the Fie. I
comprises a housing body I to the bottom 2 of which feet 3, e.g. of hard rubber are fitted. On the housing body I a vitreous ceramic top plate 4 is fitted. Underneath the vitreous .5 ceramic top plate ~, inside the body 1 a radiant heating element body ~ is mounted by the mounting means 6. being pressed against the top 4 with spring-loading. The mounting means 6 comprises a support base 7 resting on the inside of the bottom 2 of the body I. As illustrated in Fig. 2, three resilient support brackets 8 are provided on the circular support base 7.
WO 98/41059 PC"TIZW98/00003 The support base 7 is disc shaped and includes at its centre point an aperture 9 for fitting the support base 7 to the bottom 2 of the body 1. a screw 10 through the bottom 2. has been screwed into the aperture 9.
On the support base 7 three spring metal resilient support brackets 8 are provided, their longitudinal axes being each spaced anQUlarly from one another by an enclosed angle a of 120°. Each support bracket 8 comprises a base portion 11 and at an angle thereto a support arm 8' terminating in an end region comprising a shoulder 12, respectively provided with one or more apertures i3, 14 for the passage therethrough of fastening rivets 15 or screws 16. The ~upport base i includes uniformly radially spaced from its centre_ apertures 17. The base portion 11 of each support bracket 8, facing the support base 7 includes a succession of apertures ?0 (Fig. I) extending longitudinally or alternatively an oblong aperture I3 (Fig. =). Optionally one screw I6 each passes through the aperture 14 in the shoulder I2 of the resilient support bracket 8 and is screwed into the heating element body ~ in order to fix the latter.
The shoulder 12 of the support bracket 8 includes an upwardl~~ directed bent-over rim 18 which dips the side of the heating element body 5. The support base 7 on the side facin_ the base portion of the support bracket 8, comprises luss 19 serving as guide formations for the lateral containment of the support brackets 8. the lugs 19 being advantageously formed by appropriate blanking of the support base 7.
For ease of assembly and improved sideways confinement of the heating element body 5, the shoulder 12 of each support bracket terminates in an upwardly directed retaining flange 18, which in turn. for ease of manipulation terminates in an outwardly directed flange =1.
The assembly of the table model cooking appliance proceeds in that firstly the resilient support brackets 8 are fitted onto the support base 7 in accordance with the prevailing diameter of the heating element 5, preferably amounting to a standardised 140 or 180 mm, at the appropriate radial distance from the centre point of the support base 7 by means of rivets 1 S . Thereafter the heating element body ~ is placed onto the shoulders 12 of the resilient support brackets 8 and is additionally fixed m a e-6y se~tapp~'n~
screws 16. This preassernbled structural unit which already includes the heating element. may then be installed very easily in the body 1. For this purpose the support base 7 is either fitted directly to the bortom 2 of the body 1 by means of the screw 10 . or, as shown in Figs. 3 and 4, on a mounting bracket which on the bottom side connects the sides of the body, likewise by means of a screw. The latter is preferred, e.g. if a plurality of heating element bodies is to be fitted to a multiplate cooking range.
WiTlng is now also very simple, initially by means of connecting plugs and a cable manifold which likewise is preassembled. It is now merely necessary to place the top including the vitreous ceramic plate in place. whereafter the appliance including all installed internal, is reversed and screwed together from below by means of self tapping screws.

Figs. 3 and ~ differ in that in the case of Fig. 3 the heating element body is of lesser diameter. e.g. a standardised I40 mm diameter. in =0 which case the fastener. i.e. rivet 15 passes through the slot I3 of the support base 11 of the support bracket at that end of the elongate slot 13 which is closest to the bending Line connecting the base member 11 to the support arm 8'. In accordance with Fig. =1 on the other hand a heating element body of larger diameter, e.g. a standard I 8d mm element body is accommodated, and in this case the fastener 15 is positioned in the 5 slot I3 at the far end of the slot 13 closest to the centre where the screw 9 is fitted.
In Fig. 3 the support base 7 (instead of being fitted to the bottom of a table top appliance as in Fig. 1 ) is secured by a screw 10 onto a horizontal bracket 102 spanning a gap between opposite ends (not shown) of a cooking range and extending centrally 30 across the underside of the mounting system.
WO 98/41059 PCTlZW98/00003 The spring properties of the resilient support brackets are indicated in Figs.
The restraint may be brought about by the configuration of the ends of the resilient support brackets or by the fixation thereof to the marginal region of the heating t 0 element body with fasteners. e.g, screws. or preferably both.
Preferably the positions of the resilient support brackets are radiallv adjustable. More particularly the resilient support brackets are siidably guided in radial directions by _uide formations on the support base. In a preferred embodiment the resilient support 15 brackets are radiallv adjustably fixed to the support base by a radiallv extending elongate slot and screw or rivet connection. in order to provide for infinitely variable adjustment. The elongate slot is preferably provided in the end of the resilient support bracket which is to be fixed to the support base and coasts with an aperture in the support base for receiving the fastener. i.e. a screw or ri~-et. However. it will be 20 understood shat the reverse arrangement is also possible. wherein the elongate slot is provided in the support base and, in alignment therewith, the aperture for receiving the fastener passes through the end of the resilient support bracket. Furthermore, wherever the mounting is to be used for heating element bodies having a variety of fixed, standardised diameters only, the elongate slots may be replaced by a succession 25 of linearly spaced apertures to match the standardised diameters.
In preferred embodimems the upper ends of the resilient support brackets comprise an outwardly directed support shoulder terminating in an upwardly retaining member for the heating element body. Preferably.. for ease of manipulation during assembly the 30 upwardly directed retaining member in turn terminates in an outwardly directed flange.

Fig. ~ represents inside elevation a detail of an alternative embodiment of a mounting system in accordance «ith the invention: and Fig. 6 represents a view similar to Fig. = of yet a further embodiment of the mounting .0 system.
The table model cooking plate diagrammatically illustrated in the Fie. I
comprises a housing body I to the bottom 2 of which feet 3, e.g. of hard rubber are fitted. On the housing body I a vitreous ceramic top plate 4 is fitted. Underneath the vitreous .5 ceramic top plate ~, inside the body 1 a radiant heating element body ~ is mounted by the mounting means 6. being pressed against the top 4 with spring-loading. The mounting means 6 comprises a support base 7 resting on the inside of the bottom 2 of the body I. As illustrated in Fig. 2, three resilient support brackets 8 are provided on the circular support base 7.
WO 98/41059 PC"TIZW98/00003 The support base 7 is disc shaped and includes at its centre point an aperture 9 for fitting the support base 7 to the bottom 2 of the body 1. a screw 10 through the bottom 2. has been screwed into the aperture 9.
On the support base 7 three spring metal resilient support brackets 8 are provided, their longitudinal axes being each spaced anQUlarly from one another by an enclosed angle a of 120°. Each support bracket 8 comprises a base portion 11 and at an angle thereto a support arm 8' terminating in an end region comprising a shoulder 12, respectively provided with one or more apertures i3, 14 for the passage therethrough of fastening rivets 15 or screws 16. The ~upport base i includes uniformly radially spaced from its centre_ apertures 17. The base portion 11 of each support bracket 8, facing the support base 7 includes a succession of apertures ?0 (Fig. I) extending longitudinally or alternatively an oblong aperture I3 (Fig. =). Optionally one screw I6 each passes through the aperture 14 in the shoulder I2 of the resilient support bracket 8 and is screwed into the heating element body ~ in order to fix the latter.
The shoulder 12 of the support bracket 8 includes an upwardl~~ directed bent-over rim 18 which dips the side of the heating element body 5. The support base 7 on the side facin_ the base portion of the support bracket 8, comprises luss 19 serving as guide formations for the lateral containment of the support brackets 8. the lugs 19 being advantageously formed by appropriate blanking of the support base 7.
For ease of assembly and improved sideways confinement of the heating element body 5, the shoulder 12 of each support bracket terminates in an upwardly directed retaining flange 18, which in turn. for ease of manipulation terminates in an outwardly directed flange =1.
The assembly of the table model cooking appliance proceeds in that firstly the resilient support brackets 8 are fitted onto the support base 7 in accordance with the prevailing diameter of the heating element 5, preferably amounting to a standardised 140 or 180 mm, at the appropriate radial distance from the centre point of the support base 7 by means of rivets 1 S . Thereafter the heating element body ~ is placed onto the shoulders 12 of the resilient support brackets 8 and is additionally fixed m a e-6y se~tapp~'n~
screws 16. This preassernbled structural unit which already includes the heating element. may then be installed very easily in the body 1. For this purpose the support base 7 is either fitted directly to the bortom 2 of the body 1 by means of the screw 10 . or, as shown in Figs. 3 and 4, on a mounting bracket which on the bottom side connects the sides of the body, likewise by means of a screw. The latter is preferred, e.g. if a plurality of heating element bodies is to be fitted to a multiplate cooking range.
WiTlng is now also very simple, initially by means of connecting plugs and a cable manifold which likewise is preassembled. It is now merely necessary to place the top including the vitreous ceramic plate in place. whereafter the appliance including all installed internal, is reversed and screwed together from below by means of self tapping screws.
The assembly can also be fitted or replaced quite easily inside an appliance allowing 1 ~ access from below, while the vitreous ceramic top is in place.

1 and 2 to denote the same components. Figs. 3 and ~ differ in that in the case of Fig. 3 the heating element body is of lesser diameter. e.g. a standardised I40 mm diameter. in =0 which case the fastener. i.e. rivet 15 passes through the slot I3 of the support base 11 of the support bracket at that end of the elongate slot 13 which is closest to the bending Line connecting the base member 11 to the support arm 8'. In accordance with Fig. =1 on the other hand a heating element body of larger diameter, e.g. a standard I 8d mm element body is accommodated, and in this case the fastener 15 is positioned in the 5 slot I3 at the far end of the slot 13 closest to the centre where the screw 9 is fitted.
In Fig. 3 the support base 7 (instead of being fitted to the bottom of a table top appliance as in Fig. 1 ) is secured by a screw 10 onto a horizontal bracket 102 spanning a gap between opposite ends (not shown) of a cooking range and extending centrally 30 across the underside of the mounting system.
