Description
BACKGROUND OF THE INVENTION
This invention relates to demonstration apparatus, used for teaching and training and more particularly relates to a teaching device which can be used to demonstrate electrical circuits and components and their inter-relationship in electrical systems.
Technical training boards for teaching electronic circuitry generally, or the components and electrical inter-relationship of such component, in electrical systems, are known in the art. Many of such systems comprise large boards on which a multitude of circuit elements or electrical components are mounted. The instructor selects the relevant elements or components for teaching purposes, or alternatively, as an exercise, a student connects the various elements or components in order to provide appropriate circuitry therefor. Such training boards present rnany problems to both student and instructor. From the standpoint of instruction, often times many e'lements or components on the boards are not relevant to the particu-lar subject matter being taught, and therefore present a distraction to ~he student and a needless expense to the instructing institution.
Moreover, such boards are limited to the specific electrical system and demonstration function for which they were designed. Thus, if a board is designed to demonstrate or provide a training lesson in wir-ing of circuitry for a student, it does not readily permit "trouble shooting" exercises, for example where part of the circuitry is bro-ken by the instructor and the student is required to locate where the circuitry fault lies. Nor are such boards versatile: if a board is designed to demonstrate an air conditioning/heating system, an entirely new board must usually be used for demonstrating another ~43~37 kind of system unless irrelevant components are to be included.
Demonstration devices for training and teaching electrical circuits and systems and the like have been described in the prior ;
art. For example, Blum U.S. Patent No. 3,410,001 issued November~12, 1968 describes and illustrates a digital-logic trainer for demon-strating and teaching a student elements of circuitry and logic in a computer. Individual elements are releasably fixed to a peg board, each element being provided with circuit input and output connections to be wired to other elements. U.S. Patent No. 3,277,589 of Berdan `~
et al issued October 11, 1966 describes an electrical experiment kit in which electrical components are secured to spaced horizontal bars~
by means of felt/hook fasteners, the components having electrical connectors to which appropriate leads are secured.
Canadian Patent No. 727,354 of Schlag issued February 8, 1966 describes and illustrates an electronics teaching apparatus in which a number of overlay boarcls having circuit portions to be demon~
strated are fitted over a primary board having further circuit portions.
Other patents of general background interest, in that they~
describe and illustrate demonstration boards for electronics, c1r~
cuitry or the like, include Canadian Patent No. 593,617 of Purington~
issued March 1, 1960, Canadian Patent No. 770,860 of Barrow et al issued November 7, 1967, Canadian Patent No. 772,870 of Hamilton issued December 5, 1967 and U.S. Patent No. 3,203,114 of Adler issued August 31, 1965.

SUMMARY OF THE _I VENTION
According to the present invention, a device is provided for teaching electrical circuits and components and their inter-relationship in electrical systems. The device comprises a rigid, vertically oriented skeletal framework. A plurality of plane or rigid panels having flat front and rear surfaces are releasably secured, in non-overlapping relationship, with front faces oriented in the same direction to the skeletal framework leaving most of the front and rear panel surfaces operatively exposed. Securing means to releasably secure the panels to the framework are also provided.
Simulated or actual electrical components of the system to be demon-strated with their circuit leads extending therefrom are secured to ;
the panels so that the components are visible on the front surface.
Electrical connections are secured to and operatively positioned on the front surfaces of the panels. One such connection is electrical-ly connected to each circuit lead of the corresponding component.
Wire leads with attachment means at the ends thereof for electrically connecting pairs of electrical connections are also provided.
In a preferred embodiment, portions of each circuit lead are operatively exposed to the rear surface of the corresponding 3~3~
panel and are provided with on/off switches, to enable an instructor, operatiny behind the panels to create problems in the circuitry, out of view of a student, who operates in front of the panels to locake and solve the problems.
Such a device permits components to be interchanged as re-quired to alter the system being demonstrated. It enables students to wire up components or, as an exercise, an instructor to simulate a break in the circuit from behind the panels, requiring the student to locate the break in the circuit. Since the apparatus may be set up with only those components required for 3 particular demonstration, exercise or teaching lesson, the student~'s attention is not distract-ed by irrelevant components, unlike many of the prior art devices.

DETAILED DESCRIPTION OF _HE_INVENTION
In the following description, similar features have been given similar reference numerals.
Turning to Figures 1 and 2, there is shown a teaching device for electrical circuits and components according to the invention, the device being set up to illustrate for teaching or training purposes the electrical system of a domestic heating/air conditioning system. The device comprises a plurality of planar9 rigid square panels 2 secured by means of threaded thumb screws 4 to ~ ;
skeletal framework 6, the screws passing through holes 8 in panels 2 to threadably engage tapped holes 10 in the spaced vertical bars 12 of Framework 6. Bars 12 are laterally spaced from each other so that, as illustrated, adjacent bars receive opposite edges of individual panels 2, the panels being releasably secured to the framework as illustrated, in contiguous relationship. Panels 2 are secured to framework 6 with front surfacle 14 oriented in the same ~;
direction. As can be seen in the drawings, the panels are secured to ;~
framework 6 in non- overlapping relationship, most of the front and rear surfaces being operatively exposed.
Each panel 2 is made up, as required, with an appropriate component 20 of the electrical system. Obviously, where the entire framework 6 is taken up with panels 2, some of the panels 2 may have no components associated therewith; on the other hand, while not illustrated, it will be understood that more than one electrical component 20 of a system to be demonstrated may be placed on a ~3~3~7 particular panel 2. Electrical components 20, as can be seen, are secured to the panels 2 so that they are visible on front surface 14.
In the system illustrated, these components comprise a power supply (e.g. fuse box) ancl disconnect switch 21, fan center (transformer) 22, thermostat 23, fan and limit control 24, air conditioner compressor 25, gas valve/furnace simulator 26 and fan motor simulator 27. These components may be appropriately labelled for training purposes. Where it is inconvenient or impossible to actually mount the component in question to a panel 2, as in the case of compressor 25, furnace 26 or fan motor 27, simulator lights 30 are employed. In the system illustrated, compressor 25 and gas valve/furnace 26 are simulated as having two stages or levels of operation and fan motor 27 is indicated as having three speeds (low, medium ancl high).
As can be seen in more detail in Figures 3, 4 and 5, each of the electrical components 20 secured to a panel 2 has its proper electrical circuit leads 32 extending from that component, exposed at rear surface 16. Each lead 32 is electrically secured to a corresponding electrical connector 34 secured to and operatively positioned on the front surface of the corresponding panel 2. In the illustrated embodiment, these electrical connectors 34 comprise `
female sockets. Again, as illustrated, connectors 34 may be labelled, as required, so that the student or trainee will be able to identify the nature of the associated lead 32 of the particular component 20.
Appropriate wire leads 36, with male plugs 38 are also provided so that the appropriate connections sockets of the ;
components may be electrically associated, to set up the appropriate 33~ ~
circuitry for the system being illustrated.
As can be seen in Figure 5, electrical leads 32 exposed at the rear surface 16 of each panel 2 may, as desired, be provided with on/off switches 40 to enable an instructor, operating behind the panels, to interrupt one or more of these leads. A student, ; ~ ;
operating in front of the panels can then be asked to locate and analyze the circuit problem as a training exercise.
While not illustrated, it will be understood that the rear surfaces of the panels may be provided with covers so that the circuitry is not exposed (switches 40 then being mounted on such covers in operatively exposed fashion). ~ ~;
It will be understood that applicant's teaching device has many advantages over prior art devices having a similar purpose. The panels, preferably being of similar size, and being readily mountable or detached from frame 6, may be interchanged as required so that the instructor provides for the student only the components of a particular electrical system being studied. The student's attention, therefore, is not distracted to irrelevant components which often were found on prior art training apparatus. As well, applicant's invention significantly reduces the cost of such training boards, since no redundant or excess components are required, and, instead of~
requiring an entirely new training board for a different eiectrical system, selected panels with components of one electrical system can be used to set up, on the device, the electrical components of another system. The construction of applicant~'s device enables the student, facing the front surfaces of the panels, to study and create appropriate circuitry for the electrical system illustrated. The 3~7 plug/socket arrangements permits safe and easy circuit arrangement and re-arrangement by a student. As previously indicated, an instructor, operating from behind the device, can create circuit "break" for a student to locate as a training exercise. Applicant's apparatus has proven extremely effective in practice since, as much as possible, actual components of an electrical system can be displayed, thereby further enhancing the student's training by making him familiar with the appearance and operation of such components.
Thus there has been provided in accordance with the present invention a teaching device for electrical circuits and components that fully satisfies the objects, aims and advantages set forth above. While the invention has been described in conjunction with a specific embocliment thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended to embrace all such alternatives, modifications and variations as fall within the spirit and broad scope of the appended claims,
:
3~37 may be included within the spirit and scope of the invention as defined by the appended claims.
