GOSSWILLER MODULAR HOUSING SYSTEM FOR EMERGENCY VEHICLE ACCESSORY CONTROLS BRIEF SUMMARY OF THE INVENTION Police and other emergency vehicles are often equipped with a large number of accessory components with the result that a serious problem is presented with respect to the mounting of the controls for such components. The space available on or under the dash within the reach of the operator of the vehicle is often insufficient for such purposes, particularly where the controls are not arranged in an efficient and coordinated manner. Moreover, the amount of space available for such purposes and its location varies with different makes and models of vehicles so that a control housing suitable for one vehicle may be unsuitable for many others. The conventional procedure is to mount the controls for the various accessories independently of one another, in virtually any space which can be found for them, but such make-shift arrangements usually result in waste of the available space and inconvenient locating of certain of the controls.
A few attempts have been made to combine certain accessory controls in a single housing member in order to achieve greater efficiency and better utilization of the available space, but the combination control panel heretofore suggested are subject to the serious disadvantage that, if one of the controls needs to be removed for repair, the entire housing must be removed from the vehicle, thereby disabling all of the accessories operated from the common control housing, even though only one of the accessory controls is in need of repair.
It is an object of the present invention to provide a modular housing system for emergency vehicle accessory controls where a plurality of individual housing members are connected together ina selected oneof several possible arrangements so as to afford optimum convenience and efficiency depending upon the controls to be mounted and the size and location of the space available therefor.
Another of my objects is to provide a modular housing system as last above-mentioned where the number of individual housing members utilized may be varied in accordance with the number of controls to be mounted whereby the capacity of the housing assembly may be varied in accordance with the needs of a particular vehicle by'combining a selected number of modular components.
Still another object of the invention is to provide a modular housing system of the foregoing type where each of the housing members includes a removable front panel which permits the control mechanism mounted within the housing to be removed from the front thereof for repair or replacement without disconnecting any of the housing members from one another and without disturbing the control mechanism mounted in any of the other housings.
The foregoing and other objects and advantages of the invention will be apparent from the following description of a preferred embodiment thereof, taken in conjunction with the accompanying drawings.
DESCRIPTION OF THE DRAWINGS FIG. 1 is a front elevational view of a modular housing system constructed and assembled in accordance with the present invention;
FIG. 2 is a rear elevational view of the apparatus of FIG. 1;
FIG. 3 is a perspective view of the front of a modular housing system of the type shown in FIG. 1 with the front panels and the control mechanism removed from the individual housing members;

FIG. 5 is a front elevational detail view of an individual modular housing member constructed in accordance with the present invention; and
FIG. 6 is a sectional view taken substantially along the line 6-6 of FIG. 5.
Now, in order to acquaint those skilled in the art with the manner of making and using my invention, I shall describe, in conjunction with the accompanying drawings, a preferred embodiment of the invention.
DETAILED DESCRIPTION OF THE INVENTION Referring now to the drawings, there is shown in FIG. 1 an assembly comprising three modular housings 10a, 10b and which are identical to one another in size and shape and are connected together in a manner to be described hereinafter to form a unitary cluster of individual housings each for containing control mechanism for corresponding accessory equipment for a police or other emergency vehicle. For example, police vehicles are normally equipped with a two-way radio, an electronic siren, emergency lights and other special equipment, and in recent years speed computer devices have become standard equipment in a great many police vehicles.
In the embodiment shown in FIG. 1, each of the housing members 10 is generally rectangular in its configuration, and with reference to a horizontally disposed housing member such as shown at 10a it is of a length equal to two times its height so as to facilitate combining the same in both parallel and perpendicular arrangements. Thus, the housing 10a isdisposed horizontally and'the housing 10b is similarly disposed on top of the housing 10a, while the third housing 10c is vertically disposed at the ends of the two horizontal housings so as to form a combined assembly which is of overall rectangularshape and comprises two horizontal compartments and a vertical compartment each being independent of the other.
By way of example, the housing 100 may contain a control head for a speed computer, and there is shown a cover plate 12a representing a control panel or front panel for a speed computer. The housing 10b may for example contain a control head for an electronic siren, and there is shown a cover plate 12b representing a control panel or front panel for such a siren. It will be understood that either of the housings 10a or 10b could contain instead a radio control head or control mechanism for other accessory equipment of a type utilized bya police or other emergency vehicle. The housing 10::- is provided with a cover plate having six rectangular openings 14 punched therein for receiving six auxiliary switch members 16 which may be snapped into place in the openings provided therefor. Such auxiliary switches may be wiredto control various accessories such as a spotlight, revolving light, door lock, trunk lock, etc.
FIG. 3 shows the housing members 10 with the cover plates 12 and control mechanisms removed. Since the several housings are identical to one another, only the housing a will be described in detail. The housing 10a is a die-cast aluminum member having longitudinal walls 18 and 20 and transverse or vertical walls 22 and 24, the longitudinal walls being twice the length of the vertical walls. The walls 18, 20, 22 and 24 define a rectangular compartment 26 for housing control mechanism such as the speed computer control mechanism referred to hereinabove. A rear wall 28 is integral with the walls 18, 20, 22 and 24 and has a large rectangular opening 30 formed therein to permit electrical connections to be made therethrough with the control mechanism located within the housing.
Each of the four corners of the compartment 26 has an integral boss 32 formed therein which extends for substantially the full depth of the housing and in which threaded holes 34 are provided so as to permit the front cover plate 120 to be secured in position as shown in FIG. 1 by four screws 36. The bosses 32 are preferably recessed slightly from the front face of the housing 10a so as to provide room for the cover plate 12a which is designed to mount against the front ends of the bosses and be held in position by the four corner screws 36.
FIG. 4 shows the manner in which the several modular housing members 10 are interconnected by a plurality of L-shaped clip members 38. The rear of each of the housings 10 is formed with threaded holes 40 at each of the four corners thereof, such holes preferably being aligned with the threaded holes 34 in the front of the housing so as to extend into the bosses 32. Consequently, by means of a plurality of screws 42 and the L-shaped clips 38, the housings may be interconnected at their flat, coplanar rear faces by arranging the clips in a desired fashion and anchoring the same in position with the screws 42.
Each of the L-shaped clip members 38 is provided with three holes 44, and it will be seen from FIG. 4 that the clips are oriented depending upon the arrangement of the housings to be interconnected. Thus, with the housing 10b superimposed on top of the housing 10a, and with no housing to be connected at the right-hand ends thereof as viewed in FIG. 4, the clips 38a and 38b are oriented so that their unused leg portions extend inwardly in non-projecting fashion. On the other hand, at the left-hand end of the housings 10a and 10b as viewed from the rear in FIG. 4, the latter two housings must be interconnected, and in addition the vertically arranged housing 10c must be secured to the ends of the horizontally disposed housing members. Consequently, the clips 38c and 38e are arranged so that one leg projects outwardly to the left, and such projecting legs are anchored to corresponding ones of the corners of the vertically disposed housing 100 for purposes of connecting the latter to the assembly of the two horizontally disposed housing members. On the other hand, the L-shaped clip 38d does not function to support the housing 100, and thus it is arranged with the one unused leg extending inwardly to the right in nonprojecting fashion.
In the embodiment illustrated in the drawings, the clips 38b and 38c are utilized to connect the housing assembly to a mounting member 46 comprising a body portion 48 and a pair of trunnion legs 50 and 52. Thus, the connecting clip 38b is arranged to interconnect the housing 10a with the mounting member 46, with the unused leg of the clip extending inwardly in non projecting fashion. The clip 38c is arranged to connect the housing 10a with the mounting member 46, and its second leg extends outwardly to the left for connection with one corner of the vertically disposed housing 100. The mounting member 46 may be utilized to mount the housing assembly on the transmission tunnel of a vehicle floor so as to be readily accessible to the operator, although various other modes of mounting the housing assembly within a vehicle are within the scope of my invention.
FIG. 2 is a view of the rear of the housing assembly similar to FIG. 4 but showing the control mechanism mounted therein. Thus, in accordance with the previously described example, a control head 54 for an electronic siren is mounted within the housing 10b, and a control head 56 for a speed computer is mounted within the housing 10a. The control heads 54 and 56 are provided with back plates 58 and 60 respectively which protect the mechanism contained within the control heads, and such back plates will abut against the back walls 28 of the corresponding housings, while the relatively large rectangular openings 30 in such back walls will afford ample room for electrical connections to be made with the control heads. In the embodiment shown in FIG. 2, four auxiliary switches 16 are snapped into position in the front panel 12c of the vertically disposed housing 100, the two lower switch openings 14 being closed by plug members 62 which serve to close any of the openings which are not required for the mounting of auxiliary switches.
FIGS. 5 and 6 show the die-cast aluminum housing covered by a sheath 64 made of an elastomer such as vinyl or other suitable rubber-like material. The sheath 64 is a unitary member designed to encompass the entire outer surface of the four walls of the housing, and preferably the sheath is formed with a rectangular front lip portion as shown at 66 which is firmly secured in place by the front panel 12a when the latter is mounted by means of the corner screws 36. The sheath 64 serves an important safety function in that it covers the aluminum housings with an elastomer material, and in addition it may be fabricated in simulated leather grains or other designs which enhance the appearance of the modular housing members.
It will be understood from the foregoing that a wide variety of choices are available relative to the number of housings 10 to be assembled together and the mannet of arranging them with respect to one another. The number of housings utilized in a given assembly will of course depend upon the number of accessory control heads or the like to be mounted, but the arrangement of the various housings can be varied in accordance with the size and location of the space available within a given vehicle. For example, where ample space in the vertical direction is available in a location readily accessible to the operator, the housings may simply be stacked vertically one over the other, whereas if the available vertical space is limited, the overall assembly may be extended horizontally, thereby reducing the vertical space required. As previously noted, the oblong housing members 10 may be arranged vertically or horizontally, or an assembly may comprise both vertically and horizontally disposed housing members as in the embodiment illustrated in the drawings.
It is important to understand that once the selected number of housings'have been interconnected in a desired arrangement and mounted within a vehicle, it is intended that such housings will remain intact within the vehicle even though it may be necessary to remove certain of the components housed therein for purposes of repair or replacement. For example, the control head 54 for an electronic siren may be mounted in the housing b by insertion from the frontof the housing, after which the front plate 12b is secured in position by the four corner screws 36. Similarly, the front plate 12b may be removed and the control mechanism 54 taken out of the housing 10b for repair or replacement without disconnecting any of the housings 10 from one another and without disabling any of the mechanism contained within any of the other housing members. The interconnected housing members thus provide a more or less permanent framework affording a cluster of individual compartments for housing a variety of control mechanisms for an emergency vehicle, although obviously the arrangement of the housing members can be changed by removal of the clip members 38 at the rear of the housings.
An assembly of housing members in accordance with the present invention may be mounted within an emergency vehicle in a variety of ways. For example, a mounting member such as shown at 46 may be utilized to mount the housing assembly on the transmission tunnel of the vehicle floor next to the operator. Altematively, such an assembly may be mounted to the vehicle dash, or if desired it may be mounted to a tray which is simply positioned on the seat immediately next to the operator.
It will be understood that the foregoing system of modular housing members may comprise housings of more than one size, such as a plurality of oblong rectangular housings of the type illustrated in the drawings, together with a plurality of square housings one-half the size of the rectangular housings, and it is contemplated that the present invention may be practiced by using more than one size of housing. However, it is considered simpler and more expedient to utilize housings which are all of the same size, and the preferred shape for such a standard size housing is rectangular with the longitudinal dimension being twice the transverse dimension. With an arrangement of the latter type, it is possible to combine vertically and horizontally disposed housings as shown in FIG. 1 and still provide a housing assembly which is rectangular in its overall configuration, although the latter is not essential in the practice of my invention.
