Description
POWER-CONNECTION ICAR-MOUNTING STRUCTURE
OF CAR-tzIOUNTABLE APPARATUS
Background of the Invention
The present invention relates to an apparatus, such as an electric pot to be mounted inside a car, more particularly, to the structure of a power connection device and the structure of the device needed for mounting the apparatus.
Conventionally, any apparatus to be mounted inside a car, for example an electric pot, is either secured to part of the car compartment with a screw, placed on a seat or hung on window frame. However, to replace such an apparatus secured to part of a car corpartment, or to change its position or direction, the screw must be removed each time, thus being inconvenient. If such an apparatus were merely placed on a seat, it might not be safe and the apparatus may get lost. If the apparatus is hung on a window frame, shock or vibration generated during driving may disengage it. In addition, contacting parts between the apparatus and the fixing device wear out due to continuous jolting of the car, shorter ing the service life of the car-mounted apparatus.
Conventionally, any apparatus such as an electric pot is attached to a convenient part of a car compartr:ent so that it can easily be mounted and removed. Thus, while the car is running, different vibration conditions are present between the car body and the installed apparatus. Therefore, when connecting parts are firmly fixed to the apparatus and car body, they are subjected to different vibration conditions, causing them to be damaged easily. To prevent this, there is a growing demand for a reliable power-connector device resistant to vibration and capable of maintaining a satisfactory connection over a long period of time.
Summary of the Invention
To eliminate the disadvantages mentioned above, the present invention aims at providing a device for connecting the car-mounted apparatus to the power source that is completely free from wear caused by vibration and is capable of stably maintaining a satisfactory connection for a long period oX tine. The resent invention aims at providing a device for connecting a car-mounted apparatus, suc as an electrical pot, wich is resistant to vibration or the car body and Fs esil handled.

Description of the Preferred Embodiments
Referring now to the accompanying drawings, one of the preferred embodiments of the present invention is described below.
The reference numeral 1 denotes a substrate secured to an appropriate position of a'car body 2. The reference numeral 3 denotes an air pot provided with water-heating and temperature-preserving functions, which can be installed onto the substrate 1 via an elastic sorting unit 4 so that it can be freely mounted and removed.As shown in Fig. 5, the elastic support unit 4 comprises a shaft-like bolt 5 erected on the substrate 1, an engaging boss 6 coupled to the shaft 5 with free vertical movement and making up projection 7 on its external circumference, a silencer 8 made of some elastic material, such as rubber, inserted between the engaging boss 6 and the substrate 1, a spring 9 set to the external circumference of the shaft 5 and held inside the engaging boss 6 to constantly energize it in a downward direction, a circular supporter 10 provided inside the concave bottom surface of the air-pot 3, a plurality of clamp pins 11 installed on the internal surface of the circular supporter 10 at equal intervals so they can freely project into and retract from the internal surface, and springs 12 which are provided inside the circular supporter 10 and constantly energizes each of the clan.? pins 11 in the direction of projection. The air-pot 3 is installed onto the substrate 1 by first coupling the supporter 10 to the external circumference of the engaging boss 6 to cause each clamp pin 11 to be engaged with the projection 7. When the constitution of these components is completed, the air-pot 3 is elastically supported by the silencer 8 and the spring 9. When the air-pot 3 is raised by applying force, the clamp pins 11 retract, resisting the force of the spring, so that the engaging boss 6 is disengaged from the projection 7 to allow the removal of the air-pot 3.
The reference number 13 denotes an apparatus-side
connector installed beneath the bottom surface of the
air-pot 3, while the connector is provided with a pair
of electrode sheets 14. The reference numeral 15
denotes a car-side connector which is provided with grooves 16 receiving a pair of an electrode sheets 14 and
with an electrode receiving parts 17 inside of the grooves 16, while the connector 15 is supported on the
substrate 1 so that it can move freely. The reference
numeral 18 denotes concaves formed in both ends of the
car-side connector 15.The reference numeral 19 denotes a supporter metal erected on the substrate 1, while the
tip end of each of the bent members 20 is inserted into each
of the concave parts 18 and supporter metals 19 support the
car-side connector 15 so that the connector can move in
all directions within the rar.ge allowed by the concave
18. The reference numeral 21 denotes connector units
installed on both side surfaces of the car-side connec
tor 15, made of elastic material, and which engage with
both side surfaces of the apparatus-side connector 13.
The reference numeral 22 denotes the power-supply cord.
Based on the construction mentioned above, when coupling the supporter 10 supporting the air-pot 3 against the external circumference of engaging boss 6, a pair of electrode sheets 14 of the apparatus-side connector 13 are respectively inserted into the grooves 16 of the car-side connector 15 to be electrically connected to electrode receivers 17 inside of the grooveS 16. This allows power to be fed to the air-pot 3 and the connector unitS 21 to be elastically engaged with both side surfaces of the apparatus-side connector 13, and the state of connection to remain by sandwiching the connector 13.Consequently, although different conditions of vibration are present between the substrate 1 on the part of the car body 2 and the air-pot 3 while the car is running, since the car-side connector 15 can freely move within a specific range against the substrate 1, the connector 15 integrally vibrates with the apparatus-side connector 13. This prevents both connectors 13 and 15 from being destroyed due to uneven vibration between them and allows the connection to remain unaffected. Note that the first preferred embodiment described above provides the car-side connector with free movement. However, the apparatus-side connector may also be provided with free movement.
Likewise, an identical functional effect can be expected when the connection instrument is set to the apparatus-side connector. As is clear from the above explanations, the constitution embodied by the present invention provides a power-source connection device that securely maintains stable connection over a long period of time without being affected by vibration.
Referring now to Figs 6 through 8, the second preferred embodiment of the present invention is described below.
The engaging device for a car-mounted apparatus such as a car-pot reflecting the present invention includes a fixing plate 103 secured to part of a car body 101 (e.g.
the inside of a door) with screw 103a, for supporting a car-mountable instrument 102. A concave 104 used for engagement is provided in either the car-mountable instrument 102 or the fixing plate 103. A convex part 105 engaging with the concave 104 is provided on the other unit, being either the car-mountable instrument 102 or the fixing plate 103. This structure allows the concave part 104 and convex part 105 to be engaged by means of engaging members 107 supported by springs 106 so that they can freely be engaged and disengaged. In the second preferred embodiment, the concave part 104 and convex part 105 are respectively installed to the car-mounted instrument 102 and fixing plate 103.The fixing plate 103 is formed by a stationary plate 103b secured to the car body 101, a convex sheet 103c that projects from the car body 101 to form a gap 108 between the car body 101 and fixing plate 103, and erection plateS 103d which is integrally attached to the convex plate 103c and stationary plate 103b. The convex part5 used for engagement is provided in the substantially center part of the front surface of the convex plate 103c.
The convex part 105 is made from hard plastic resin, while the tip portion of the convex part 105 has a diameter dl and the convex part 105 has a maximum diameter of d2
The convex part..l05 is formed in a mushroom-like structure as follows. The convex part 105 comprises an umbrella-like first incline 105a pressing against the emgaging members 107 supported by the springs 106 when the convex part 105 is engaged with the concave part 104, a second incline 105b which is provided with an incline inverting the first incline 105 which externally supports the engaged convex part 105 and
concave part 104 when engaged with each other, ar.d a
neck part 105c connected to the second incline 105b and provided with a diameter d3 as shown in FIGS. 6 and 8.The
second incline 105b is provided with an angle steeper
than that of the first incline 105a. The convex part
105 is secured to the convex 103C with a screw 109. The
screw 109 is provided with a nut 109a at its lower end
through convex plate 103c. The head part 109c of the
screw 109 comes into contact with the bottom surface of
the center concave part 105e of the convex part 105.
The convex 105 is then secured to the fixing plate 103
with the head part 109c of the screw 109 and the nut
109a. The concave 104 is provided with a space 110
allowing the entry of part of the tip end of the convex
part 105 when the convex 105 is engaged with the concave
part 104. A case 111 is secured at four positions of
the inner circumferential wall of the convex 104. The engaging member 107 projects itself from a through-hole
llla of the case 111 towards the center of the concave
part 104. The case 111 is internally provided with a supporting member 107a which is integrally connected with the engaging member 107. The spring 106 that energizes the engaging member 107 towards the center of the concave
part 104 is installed between the support member 107a and
the inner wall of the case 111.When the convex part
105 enters the engagement, the engaging member 107 comes
into contact with the first incline 105a and the second
incline 105b of the convex part 105, then disposed to
the position for engagement with the second inline 105b.
Consequently, the width of both sides of the concave
part 105 is almost equivalent to the maximum diameter d2
of the concave part 105, whereas the width of both sides
of the space 110 is slightly wider than the tip diameter
dl of the convex part 105. Next, the function
of these components is described below. Actually, the
user of the electric pot first engages the concave part 104 of the car-mounted instrument 102 with the convex part 105 by inserting it by hand. When it happens, the
first inclines 105a formed on the convex part 105 is
pressed against by the engaging member 107. This is due
to the presence of the supporting member 107a supporting the engaging member 107.When the user further presses
the car-mounted instrument 102 for closer engagement,
the elastic force of the spring 106 causes the engaging member 107 to move across the first incline 105d and
engage with the second incline 105b, thus allowing the
convex part 105 to be fully inserted into the
concave part 104. Since the engaging member 107 is
engaged with the second incline 105b, even when the car
body 101 is vibrating, the car-mounted instrument 102 is
prevented from being disengaged from the car body 101.
In addition, since the width of both sides of the
concave is almost equivalent to the maximum diameter d2
of the convex part 105, when the engaging member 107
moves across the first incline 105a, the engaging member
107 is fully inserted into the case 111. Conversely,
when removing the car-mounting instrument 102 from the
fixing plate 103, the user manually pulls out the
car-mounting instrument 102 from the fixing plate 103 to allow the engaging member 107 to move across the second
incline 105b, so the car-mounting instrument 102 is then
easily removed. In this second embodiment, a concave
part and convex part are respectively provided for the
car-mounting instrument and the fixing plate. Converse
ly, it is also possible for the system to provide a
concave part on the fixing plate part and a convex part on the car-mounting instrument part.It is also possi- ble for the system to provide the engaging member on the convex part instead of the concave part.
As is clear from the foregoing explanations, the present invention relates to the engaging device of a car-mounted instrument featuring the provision of a fixing plate to support the car-mounted instrument on part of a car body, a convex part in either the car-mounting instrument or the fixing plate, and a concave part for engaging with the convex part on either the car-mounted instrument or the fixing plate, and engagement of the concave and convex parts by means of engaging means supported by spring means so that they can freely be engaged and disengaged.
According to the present invention, since a car-mounted apparatus such as an electric pot can withstand continuous vibration of the car body by the engagement of a concave part with a convex part using spring means, and also be removed easily from the engaged fittings, users can handle a car-mounted electric pot more conveniently while driving.
Referring now to Figs 9 and 10, the third preferred embodiment of the present invention is described below.
Explanations of those parts identical to those which are explained in the second embodiment (Figs 6 through 8) shall be deleted except for the reference numerals given below. The third embodiment features a construction which includes the concave part 104 formed in the car-mounted apparatus 102, the convex part 105 provided on the fixing plate 103 for engagement with the concave 104, the first spring A provided between the convex part 105 and the fixing plate 103 supporting the convex part 105, and the engagement of the concave part 104 with the convex part 105 by means of engaging members 107 supported by second springs06 so that they can freely be engaged and disengaged.
The tip ends of the first incline 105 are of length dl as shown in Figs 9 and 10. The maximum diameter of the bottom of the first incline 105a is designed to be d2, and the neck part 105c is of length d3. The convex part 105 is secured to the projected plate 103c with a screw 109 penetrating the center of the convex part 105.
A nut 109a is set to the bottom end of the screw 109 through the projected plate 103c.
The first spring A is provided between the bottom surface of the head-part 109c of the screw 109 and the bottom surface of the central concave 105e which is vertically provided in the convex part 105, while the convex part 105 is secured to the fixing plate 103 with the head part 109c of the screw 109 and the nut 109a.
In addition, a sound absorber 109d having a buffering function is provided between the convex 105 and the projected plate 103c.
Now, while the car body 101 incurs less vibration, the car-mounted apparatus 102 securely remains on the projected plate 103c. However, when vibration intensifies, as shown in Fig. 10, the car-mounted apparatus 102 is disengaged from the projected plate 103c.
Nevertheless, since the convex part 105. can move its position by means of the first spring A, the first spring A functions as a buffer, even if the car-mounted apparatus is disengaged from the projecting plate 103c, and the concave part 104 and convex parts 105 cannot be disengaged immediately. As was already explained in reference to Figs 1 through 3 in the first preferred embodiment of the present invention, although the fixing plate 1 on the part of the car body 2 and the car-mounted apparatus 3 generate vibrations different from each other, since the connector unit 15 on the part of the car body can freely move within a specific range against the fixing plate 1, the connector unit 15 integrally vibrates together with the connector unit 13.
Thus, the connectors 13 and 15 cannot be affected by the effect of different vibrations. These connectors, however, can remain securely connected. In the third preferred embodiment, a concave part is provided for the car-mounted apparatus and a convex part for the fixing plate to implement their engagement. Conversely, it is also possible for the system to provide the concave part on the fixing plate and the convex part on the car-mounted apparatus. In addition, it is also possible for the system to provide an engaging member on the convex part instead of the concave part, as in the preceding preferred embodiment.As is clear from the foregoing explanations, the present invention relates to a device for engaging the car-mountable apparatus with the car-body, which is comprised of the rolloning: a fixing plate for securing the car-mounted apparatus to the car body, a concave part formed in either the car-mounted apparatus or fixing plate, a convex part formed on either the car-mounted apparatus or a fixing plate for engagement with the concave part, .a first spring provided for either the convex part or concave part for buffering vibration of the car-mounted apparatus,
'and an engaging member held by a second spring, which causes the concave and convex parts to be freely engaged and disengaged.Thus, according to the present invention, since a car-mounted apparatus such as an electric pot can withstand continuous vibrations of the car body by the engagement of a concave part and a convex part using spring means and can also be easily removed from the engaged members, a car-mounted electric pot can be used more conveniently while driving.
Referring now to Figs 11 through 14, the fourth preferred embodiment of the present invention is described below. The device for engaging any car-mountable apparatus such as an electric pot related to the present invention comprises a metallic fixing plate 203 made, for example of iron, supporting a car-mountable apparatus 202 is secured to part of a car-body 201, such as the inside of a door, with a screw 203a a concave part 204 formed in either the car-mounted apparatus 202 or the fixing plate 203y a convex part 205 which is freely engaged with and disengaged from the concave part 204 provided in either the car-mounted apparatus 202 or the fixing plate 203 and a magnetic substance 206 set to the bottom part of the concave part 204 and sandwiched by a pair of steel sheets 207, while the convex part 205 is made of a suitable material, such as iron, to which the magnetic substance 206 can attach itself. The fixing plate 203 comprises a top plate 203b of a convex part projected inside the car body 201, a stationary plate 203c secured to the car body 201 with the screw 203a, and an incline 203d that connects the plates 203b and 203c, these plates being integrally formed by either being pressed or contracted. (Fixation of other members may be done by welding). The convex 205 is comprised of the top plate 203b and the incline wall 203d of the convex 205.The concave 204 comprises a bottom plate 202a
forded in the bottom surface cf the car-oted apparatus 202, a plate 202b that adheres to and
separates from the stationary plate 203c, and incline
wall 202c that extends itself to the plates 202a and
202b. A pair of long holes 208 are provided for both
sides of the concave bottom plate 202a. A sheet-shaped
first supporter 209 is set to the upper portion of the
concave 204 for holding the steel sheets 207, while the
first supporter 209 is provided with holes 210. The
steel sheets 207 are installed by penetrating the long
holes 208 and the supporting holes 210. The magnetic
substance 206 is provided between a pair of steel sheets
207, while cutout portions 207a are formed on botch sides
of the upper part of the steel sheets 207. The cutout
portions 207a provide engaging members 207b on both sides
of the upper portion of the steel sheets 207 for engaging these members with the first supporter 209.
Supporting holes 210 are respectively formed in a cross
shape by means of long-holes 210A and small holes 210B
on both sides of the center of the holes 210.
The length A of the long hole 210A corresponds to the
width of the steel sheet 207 and the width B between
both sides of the long hole 210A is at least wider than
the thickness of the two pieces of the steel sheet 207
The full length C of a small hole 210B in supporting
hole 210 is substantially identical to the width of the cutout portion 207a of the steel sheet 207. The engaging member 207b of
the steel sheet 207 is engaged with the hole wall 210a
of the small hole 210B in the supporter 209. The first
supporter 209 is held by the second supporter 211 which
is formed in the side of concave part 204.
Next the functions of these component members are
described. The convex part 205 formed on the fixing
plate 203 is inserted into the concave part 20t formed
in the car-mountable apparatus 202 so that these can be
engaged with each other. At the same time, the first
convex member 207a formed on the steel sheet 207 is
pressed against the convex ceiling plate 203b. This is
because the magnetism of the magnetic substance 206
attracts the metallic convex ceiling plate 203b through
the steel sheet 207. The attracting force of the
magnetic substance 206 is insufficient in the sliding
direction (which corresponds to direction D shown in
Fig. 14).Thus, when an attracting force is applied to the car-mounted apparatus in the sliding direction, due to inertia generated at the moment the car stops, the
inclines 202c and 202d of the concave part 204 and the
convex part 205 respectively are engaged with each other to prevent the steel sheet 207 from sliding towards the convex ceiling plate 203b. This increases the attraction and retention effect against vertical and horizontal vibration of the car body. In addition, when installing the car-mountable apparatus 202 to the fixing plate 203 from the upper position, the concave and convex configuration serves for guiding the positioning of the apparatus.If it is necessary to manually carry the car-mountable apparatus 202, the user first holds the apparatus with his hand and then lift it up from the fixing plate 203 by applying greater force than the magnet attracting force generated by the magnetic substance 206.
When engaging the steel sheet 207 with the supporting hole 210 during assembly, the following processes are executed. First, the surfaces of 1a pair of steel sheets 207 are aligned with each other, and penetrate through the long hole 210A in the supporting hole 210. The steel sheets 207 are then separated from each other.
Next, the engaging member 207b is engaged with the hole wall 210a in the small ole 210B by inserting the cutout portion 207a formed on each steel sheet 207 into the small hole 210B. The magnetic substance 206 is then sandwiched by these steel sheets 207 to allow the magnetic substance 206 to attract the steel sheets 207.
Next, the lower parts of the steel sheets 207 held by the supporter 209 are respectively pushed outward from the long holes 208 of the concave part 204, and finally the first supporter 209 and the second supporter 211 are respectively fixed. In the fourth preferred embodiment, the concave and convex parts are respectively provided for in the car-mountable apparatus and fixing plate.
Conversely, it is also possible for the system to provide the concave part on the fixing plate and the convex part on the car-mounted part.
The tip end of the steel sheet 207 corresponds to the position of the bottom part of the car-mounted apparatus 202 by a specific distance (h). If the tip end of the steel sheet is either flush with or projects from this position, when actually coupling the apparatus 202 to the fixing plate 1G3 attached to the car body by using magnetic attraction, any substance susceptible to magnetism may obstruct it. As a result, the car-mounted apparatus 202 cannot correctly be engaged with the designated position of the fixing plate 203.
As is clear from the foregoing explanations, the present invention relates to a device for engaging a car-mounted apparatus, which comprises a fixing plate for supporting a car-mounted apparatus on part of the car body a concave part provided on either the car-mounted apparatus or the fixing plate) a convex part engaged with the concave part provided on either the car-mounted apparatus or the fixing
plate a magnetic substance secured the bottom part of the concave part so that the convex part is of material susceptible to magnetism.According to the present invention, the car-mounted apparatus is secured to the fixing plate by means of the attractive force of a magnetic substance so that it can freely engage with and disengage from the fixing plate, and accordingly, when the car-mounted apparatus is carried, it can easily be removed from the fixing plate. In addition, due to the combined effect
of the magnetic attractive force and the engagement of
the concave and convex parts, the coupled unit is
durably resistant to vibration of the car body, thus
providing users with better handling convenience.
The power-connection device for a car-mounted apparatus
described in conjunction with the first preferred
embodiment is provided with a pair of electrode sheets
14. The electrode sheets 14 may be of identical length,
and three electrode sheets may also be used instead of
two.
Conventionally, according to the electrical capacity
available, dual-lin and triple-line wiring arrangements
are usual for car-mounted apparatuses. These wiring
constitutions are respectively shown in Figs 18 and 19.
The dual-line wiring diagram shown in Fig. 18 comprises
a power-supply line a' and a ground (earth) line b'. The
triple-line wiring diagram shown in Fig. 19 is for a
greater electrical capacity and comprises a power-supply line c', a ground line d', and a control line e', in which
conduction of power through the power-supply line c' is
controlled by a relay f'.
Figs 15 and 16 respectively denote the relationship between the respective electrode terminals of electrical appliances which are provided with a triple-line wiring constitution and those parts allowing the insertion of electrodes. Fig. 15 denotes the following constitution:
Of those electrode terminals 321, 322, and 323 which are provided in the lower part of an electrical apparatus 301, electrode terminal 322 of the control circuit provided in the center position is shorter than electrode terminals 321 and 323 of the power-supply circuit located on both sides of the terminal 322. On the other hand, the configurations and heights of electrode insertion ports 331, 332, and 333 respectively positioned on substrate 302 and correspond to the electrode terminals 321, 322, and 333, are identical. Electrode terminal 322 of the control circuit is shorter than electrode terminals 321 and 323 of the power-supply circuit by length "Q2". When provisionally placing an electrical apparatus 301 on the substrate 302, electrode terminals 321 and 323 respectively come into contact with the corresponding electrode insertion ports 331 and 333 on the substrate 302, whereas the electrode terminal 322 in the center position remains disconnected from the corresponding electrode insertion port 332. Fig. 16 denotes the following constitution. Electrode terminals 324, 325, and 326 which are provided in the lower part of the electric apparatus 301 respectively have different lengths. Of these, the electrode terminal 324 of the power-supply circuit shown to the left is the longest, whereas electrode terminal 325 of the control circuit in the center is the shortest.In other words, electrode terminal 326 shown to the right is shorter than electrode terminal 324 shown to the left by length 2Q4 In addition, electrode terminal 325 in the center is shorter than electrode terminal 326, shown to the right, by length "23". When the electrical apparatus 301 is merely and provisionally placed on substrate 302, only the electrode terminal 324 shown to the left comes into contact with the corresponding electrode insertion port 334 on the substrate 302, or the electrode terminals 324 and 326 on both sides respectively come into contact with the corresponding electrode insertion ports 334 and 336 on substrate 302, whereas the electrode terminal 325 in the center and the corresponding electrode Insertion port 335 do not come into contact with each other.As a result, it is possible for the power-supply connection device to prevent electrodes from being damaged. Fig. 17 denotes the relationship between electrode terminals 327 and 328 of electrical apparatus 301 having a dual-line wiring constitution and electrode insertion ports 337 and 338 provided on the substrate 302. The electrode terminal 328 of the power-supply circuit is shorter than that of the other electrode terminal 327 of the power-supply circuit by length "Q5". When the electrical apparatus 301 is temporarily placed on the substrate 301, electrode terminal 328 and the corresponding electrode insertion port 338 on the substrate 302 remain unconnected with each other.By implementing the construction described above, even when the electrical apparatus 301 is placed temporarily on the substrate 302, since.no voltage is applied to the electrodes of the power-supply circuit, even if the connection is unstable, no electric arc is generated, thus preventing the electrodes from being damaged. Needless to say, in any of the circumstances shown in Fig. 15 through Fig. 17, when the electrical apparatus 301 is securely fixed on the substrate 302, electrode terminals, though being made short, are long enough to be securely inserted into the electrode insertion ports. In the preferred embodiments as shown in Figs 15 through 17 described above, the objects are achieved by varying the length of the electrode terminals.It is also possible for the system to obtain the same result by varying the lengths of the electrode insertion ports but keeping the length of the electrode terminals identical, or by varying the vertical position of the electrode insertion ports by providing a concave and convex on the upper surface of a substrate 305.
As expressly described above, according to the power-connection structure applied to electrical apparatus es reflecting the preferred embodiments of the present invention, it is possible for the system to securely prevent an electric arc from being created by inadequate electrical connection when the apparatus is merely placed on a substrate without securely being fixed, and, therefore, avoid unwanted damage to the electrodes.
In the foregoing preferred embodiments of the present invention, explanations have been made with reference to an electric pot for use in a car. However, the spirit and scope of the present invention is not limited to the use of the electric pot, but the present invention may
De applied to other kinds cf car-mountable electric appliances as well. Needless to say, applicability of the present invention is not confined to those preferred embodiments cited above, but a variety of modifications and changes may be applied to these embodiments within the spirit and scope of the present invention.
While only certain embodiments of the present invention have been described, it will be apparent to those skilled ir. the art that various changes and modifica- tions may be made therein without departing rrc.m the spirit and scope cf the present invention as claimed.
It will be appreciated that the invention is in general applicable where an electrical appliance
is to be mounted on a support body which is part of or attachable to a structure, such as a vehicle body, which is liable to vibration and/or shock.
