Abstract
Abstract A mirror construction comprising an elongate body, an elongate arm one end of which is connected to the body, a mirror connected by an angleable connection to the other end of the arm, the arm and mirror being extendable between a storage condition in which the arm and mirror lie in close juxta-position to the body and an operable condition in which the arm extends away from the body with the mirror at a distance from the body, adjustment mecha-nism extending along the arm to adjacent the body for adjustment of the mir-ror about the angleable connection, a light-emitting element positioned ad-jacent the mirror and a battery carried by the body.
Description
~043;~5 This invention relates to mirror constructions.
Problems are often experienced in the observation of generally in-accessible locations. For example, there are many occasions in the home when it is necessary to carry out repairs or maintenance in awkward situations such as beneath furniture or under floors. Also in industry many occasions arise when it would be convenient to have a small mirror to view awkwardly placed assembly or maintenance areas.
It has been proposed in United States Patent specification 2,929,918 and 3,003,397 to provide elongate arms on which adjustable mirrors are mounted.
In each case the angle of the mirror can be adjusted from a remote end of the arm.
However neither of these constructions is particularly portable.
The elongate arm in each case would make it a difficult construction to store and it could be impossible to place it in an ordinarily sized pocket since neither proposes the folding of the arm and storage of the mirror in a storage condition.
Fbrthermore, the tilting of the mirror is restricted to a single axis so ;~iting the area which can be viewed without rotating the arm.
According to one aspect of the in~ention a mirror construction com-prises an elongate body, and an elongate arm, one end of which carries a mirror and the other end of which is piVotally connected to the body for swing-ing between an operating position in which the arm extends away from the body, with the mirror at a distance from the body, and a storage position in which the arm extends lengthways of the body, being housed within an open recess formed in the body.
Such constructions make it possible for the mirror to be of substan-tial length yet be of reduced length when not required.
Preferably, the arm includes first and second elongate sections which are pivotally connected together end to end, and the end of the first -1- ~
elongate section remote from the pivotal cor,nection to the second elongate section constitutes the said other end of the arm, and, in the storage posi-tion, the first section is housed within the said open recess, with the pivotal connection to the second section adjacent one end of the body, and the second section being housed in a second open recess formed in the body, the two recesses opening in opposite directions~
The invention may be carried into practice in a number of ways but one specific embodiment will now be described by way of example with reference to the accompanying drawings in which:-Figure 1 is a perspective view from above and one side of a mirror in an open position according to the present invention;
Figure 2 is a plan view of the mirror shown in Figure l;
Figure 3 is a side elevation of the mirror of Figure 2;
Figure 4 is a side elevation of the mirror in a closed position;
Figure 5 is a perspective view from above and one side of themirror in a partially folded or closed condition;
Figure 6 shows the mirror in an untilted condition;
Figure 7 shows the mirror in a tilted condition;
Figure 8 is a scrap perspective view of one of the hinge connections of the arm; and Figure 9 is a circuit diagram.
The construction shown includes a housing generally indicated at 10 and formed from a number of plastics mouldings. Pivotally cor~ected to the housing 10, by means of a hinge 12 shown in Figure 5, is an arm generally indicated at 11. The arm is formed in two sections llA and lIB, the former being connected to the housing 10 by the hinge 12 and the latter section llB carrying a head 13 which includes a mirror 14 capable of adjustment in a manner to be described. The two sections llA and llB are formed as plastics mouldings of generally U-section and are pivoted together by a further hinge 15. The adjacent ends of the sections llA and llB are shown in detail in Figure 8 from which it will be seen that the section llA carries a tongue 21 having a hook 22 adapted to engage a recess 23 on the section llB when the parts are in alignment as shown in Figure 1 so as to hold the joint at the hinge 15 rigid.
Referring to Figure 5, the head 13 is generally rectangular having a transverse wall 13A through which the section llB of the arm extends.
This section of the arm is rigidly connected to the head in any suitable manner, for example by interengagement of suitable plastics parts integrally formed on the arm at the head. The sides 13B of the head are formed with a number of ridges 13C to enable the mirror head 13 to be gripped between finger and thumb when it is desired to open out the construction from the Figure 4 position.
Extending between the sides 13B of the head is a web 13D and mounted in the head, one on each side of the arm llB, are a pair of lamp bulbs 16 which are retained against brackets 17 by means of a spring clip 18. Suitable power connections are made to the brackets 17 on the one hand ahd the spring clip 18 on the other hand to enable the lamps to be illuminated when desired.
It is to be noted from Figure 5 that the web 13D has a pair of rectangular lensed apertures 20 one for each lamp which enables the construction to be used as an ordinary flashlight when in the Figure 4 position.
Mounted in the hou~ing 10 as shown in Figure 5 are four batteries 25, only one of which is shown. The batteries are arranged in pairs one pair on each side in suitably mounted channels 26 which are covered by a pair of longitudinal lids 27 one of which has been removed for clarity.
Continuing to refer to Figure 5, the moulding from which the housing 10 is produced affords a transverse web 28 which, adjacent the upper end of Figure 5, is positioned between a pair of longitudinal webs 29 so as to form on each side of the web 28 a pair of channels 30 and 31. The channels are 1~)43315 of such a width that they snugly receive the sections llB and llA respectively of the arm 11 when the construction is in a folded or storage condition. Thus, assuming as in Figure 5 that the construction is being folded, the arm section llA is about to enter the channel 31 and as the arm section llA is folded downwards to accomplish this, the hinge connection 15 will approach a cut-out 33 in the web 28. This cut-out is also shown clearly on the righthand end of Figure 1. This permits the arm section lIB to be pivoted through 180 from the extended position of Figures 1, 2 and 3 to the storage position of Figure 4 in which it can be readily inserted in a pocket and retained therein by means of a spring clip 35 shown in Figure 4. The arm sections llA and llB
carry small integral protuberances 36 to engage recesses such as the recess 37 in order to maintain the parts lightly engaged in the storage condition.
To facilitate the snug reception of the head 13 and mirror 14 in the housing 10 it will be observed from Figure 5 that side walls 38 of the housing are reduced in the regions 39 in order to receive the sides 13C of the head 13.
The end of the arm section llA adjacent the hinge 12 is enlarged to form a generally rectangular box 40 as can be most clearly seen from Figure 1. In o~der to receive this box of the arm llA in the housing~ the channels 30 and 31 terminate adjacent the end of the web 28 shown in Figure 5 where-after the walls 29 are stepped outwards to provide two further spaced walls 41 between which the box 40 is received. Mbans may be provided to latch the box in the open position of Figure 1.
The box 40 provides a location for a knurled control knob 42 which can either be rotated about its longitudinal axis or be moved to and fro along this axis in order to adjust the mirror. The longitudinal movements of the knob 42 tilt the mirror upwards and downwards whilst the rotary movements move the mirror bodily about a pivot connection to be described. To transfer the longitudinal and rotary movements of the knob 42 to the mirror a longitudinal ~43315 adjustment assembly extends the length of the arm 11. The adjustment assembly includes a pair of metal longitudinal split tubes 45 and 46 which are retained in the U-shaped channels forming the sections of the arm llA and llB by means of pairs of tongues 47. The adjacent ends of the tubes 45 and 46 are inter-connected by an open-wound coil spring 48. The righthand end of the tube 45 in Figures 6 and 7 is connected to the adjustment knob 42. A further spring 50 extends from the lefthand end of the tube 46 into a bore 51 in a collar 52 formed as part of the plastics moulding of a mirror backing 53. The collar 52 has a pair of shoulders 55 which locate a ring 57 having a pair of arms 58 integraIly formed thereon which extend upwards and to the right in Figure 6 and which are pivoted at 59 to a pair of ears 62 formed on the end of the arm section IIB.
The operation of this mechanism is as follows. ~liding longitudinal movement of the control knob 42 is transmitted to the collar 52 by means of the tubes 45, 46 and springs 48 and 50. For example, movement of the control knob 42 from the Figure 6 position to the Figure 7 position tilts the mirror progressively to a~y desired angle up to approximately a right angle about the pivots 59. It is possible alternatively or in addition precisely to rotate the mirror about the.axis of the collar 52 by a rotary movement of the knob 42. The spring 48 will transmit rotary movement from the tube 45 to the tube 46 which in turn transmits rotary movement to the collar 52 by means of the spring 50. For this purpose the springs 48 and 50 are a tight fit on the tubes 45 and 46 and also the spring 50 is a force-fit in the collar 52.
During folding of the arm sections llA and llB the spring 48 can move slightly outwardly of the arm sections as shown in Figure S since the hinge 15 does not include a hinge pin trapping the spring.
The electric circuit for this construction is shown in Figure 9.
It includes four batteries 25 arranged in two pairs the individual batteries of a pair being in series and the pairs together being in parallel. From the negative terminals at the lower ends of the lowermost batteries leads 65 extend to a slide switch 66 mounted on the housing as can be seen from Figures 1, 2 and 3. From the uppermost positive terminals of the uppermost batteries a further lead 67 extends to the spring clip 18 shown in Figure 5. From the other side of the switch 66 a further lead 68 extends to the brackets 17 shown in Figure 5. The leads 67 and 68 are made of fine wire which can, for example, extend up the tubes 45 and 46, sufficient slack being provided, for example by way of loops or coils in the wire, to enable the wiring to accom-modate changes in the overall length of the longitudinal adjustment assembly when the knob 42 is moved to and fro. If desired, one of the wires may be largely replaced by employing the arm sections llA and llB, together with the springs, to carry current. Alternatively, parts of the wiring can be provided in the form of printed circuits.
It is believed that the operation of the device will be clear. It is readily unfolded from its Figure 4 position, in which the mirror faces in-wardly and is thereby protected, by gripping the sides 13C of the head 13 and drawing the head 13 away from the housing 10. Thereafter, the arm sections llA and llB can be unfolded and latched in the open position of Figures 1 to 3. Thereafter, the mirror can be readily adjusted as described by longitudinal and rotary movement of the control knob 42. By using the spring 50 effectively as a universal joint these movements can be carried out simultaneously. When it is desired to close the construction to the Figure 4 condition, the knob 42 is adjusted to get the mirror flat in the position of Figure 3. Thereafter, the arm sections llA and IlB are folded through the Figure 5 position until the section llA lies in the channel 31 of the housing and the hinge 15 is received in the cutout 33. Finally~ the arm section lIB is folded into the channel 30 and latched in position. The mirror is received between the side walls 38.
If desired, the mirror may be two-sided. For example, one side may _6--1~43315 be plain and the other side curved for magnification. Additional clip-on mirrors may be incorporated as desired. Moreover, the entire mirror head can be made removable, for example by a press-fit socket to enable other mir-rors to be fitted, or a damaged one to be replaced.
To maintain the mirror in any set position, friction means may be provided. As an alternative to the lamp bulbs being fixed on the arm, they can be secured to the mirror and move with it. As an alternative to position-ing a pair of bulbs in the region of the mirror, it is envisaged that a single bulb could be positioned on the housing and a series of optic fibres be arranged to conduct the light to the region of the mirror.
Problems are often experienced in the observation of generally in-accessible locations. For example, there are many occasions in the home when it is necessary to carry out repairs or maintenance in awkward situations such as beneath furniture or under floors. Also in industry many occasions arise when it would be convenient to have a small mirror to view awkwardly placed assembly or maintenance areas.

The construction shown includes a housing generally indicated at 10 and formed from a number of plastics mouldings. Pivotally cor~ected to the housing 10, by means of a hinge 12 shown in Figure 5, is an arm generally indicated at 11. The arm is formed in two sections llA and lIB, the former being connected to the housing 10 by the hinge 12 and the latter section llB carrying a head 13 which includes a mirror 14 capable of adjustment in a manner to be described. The two sections llA and llB are formed as plastics mouldings of generally U-section and are pivoted together by a further hinge 15. The adjacent ends of the sections llA and llB are shown in detail in Figure 8 from which it will be seen that the section llA carries a tongue 21 having a hook 22 adapted to engage a recess 23 on the section llB when the parts are in alignment as shown in Figure 1 so as to hold the joint at the hinge 15 rigid.
Referring to Figure 5, the head 13 is generally rectangular having a transverse wall 13A through which the section llB of the arm extends.
This section of the arm is rigidly connected to the head in any suitable manner, for example by interengagement of suitable plastics parts integrally formed on the arm at the head. The sides 13B of the head are formed with a number of ridges 13C to enable the mirror head 13 to be gripped between finger and thumb when it is desired to open out the construction from the Figure 4 position.
Extending between the sides 13B of the head is a web 13D and mounted in the head, one on each side of the arm llB, are a pair of lamp bulbs 16 which are retained against brackets 17 by means of a spring clip 18. Suitable power connections are made to the brackets 17 on the one hand ahd the spring clip 18 on the other hand to enable the lamps to be illuminated when desired.
It is to be noted from Figure 5 that the web 13D has a pair of rectangular lensed apertures 20 one for each lamp which enables the construction to be used as an ordinary flashlight when in the Figure 4 position.

The channels are 1~)43315 of such a width that they snugly receive the sections llB and llA respectively of the arm 11 when the construction is in a folded or storage condition. Thus, assuming as in Figure 5 that the construction is being folded, the arm section llA is about to enter the channel 31 and as the arm section llA is folded downwards to accomplish this, the hinge connection 15 will approach a cut-out 33 in the web 28. This cut-out is also shown clearly on the righthand end of Figure 1. This permits the arm section lIB to be pivoted through 180 from the extended position of Figures 1, 2 and 3 to the storage position of Figure 4 in which it can be readily inserted in a pocket and retained therein by means of a spring clip 35 shown in Figure 4. The arm sections llA and llB
carry small integral protuberances 36 to engage recesses such as the recess 37 in order to maintain the parts lightly engaged in the storage condition.
To facilitate the snug reception of the head 13 and mirror 14 in the housing 10 it will be observed from Figure 5 that side walls 38 of the housing are reduced in the regions 39 in order to receive the sides 13C of the head 13.
The end of the arm section llA adjacent the hinge 12 is enlarged to form a generally rectangular box 40 as can be most clearly seen from Figure 1.

Mbans may be provided to latch the box in the open position of Figure 1.
The box 40 provides a location for a knurled control knob 42 which can either be rotated about its longitudinal axis or be moved to and fro along this axis in order to adjust the mirror. The longitudinal movements of the knob 42 tilt the mirror upwards and downwards whilst the rotary movements move the mirror bodily about a pivot connection to be described. To transfer the longitudinal and rotary movements of the knob 42 to the mirror a longitudinal ~43315 adjustment assembly extends the length of the arm 11. The adjustment assembly includes a pair of metal longitudinal split tubes 45 and 46 which are retained in the U-shaped channels forming the sections of the arm llA and llB by means of pairs of tongues 47. The adjacent ends of the tubes 45 and 46 are inter-connected by an open-wound coil spring 48. The righthand end of the tube 45 in Figures 6 and 7 is connected to the adjustment knob 42. A further spring 50 extends from the lefthand end of the tube 46 into a bore 51 in a collar 52 formed as part of the plastics moulding of a mirror backing 53. The collar 52 has a pair of shoulders 55 which locate a ring 57 having a pair of arms 58 integraIly formed thereon which extend upwards and to the right in Figure 6 and which are pivoted at 59 to a pair of ears 62 formed on the end of the arm section IIB.

For example, movement of the control knob 42 from the Figure 6 position to the Figure 7 position tilts the mirror progressively to a~y desired angle up to approximately a right angle about the pivots 59. It is possible alternatively or in addition precisely to rotate the mirror about the.axis of the collar 52 by a rotary movement of the knob 42.

It is readily unfolded from its Figure 4 position, in which the mirror faces in-wardly and is thereby protected, by gripping the sides 13C of the head 13 and drawing the head 13 away from the housing 10. Thereafter, the arm sections llA and llB can be unfolded and latched in the open position of Figures 1 to 3. Thereafter, the mirror can be readily adjusted as described by longitudinal and rotary movement of the control knob 42. By using the spring 50 effectively as a universal joint these movements can be carried out simultaneously. When it is desired to close the construction to the Figure 4 condition, the knob 42 is adjusted to get the mirror flat in the position of Figure 3. Thereafter, the arm sections llA and IlB are folded through the Figure 5 position until the section llA lies in the channel 31 of the housing and the hinge 15 is received in the cutout 33. Finally~ the arm section lIB is folded into the channel 30 and latched in position. The mirror is received between the side walls 38.
If desired, the mirror may be two-sided. For example, one side may _6--1~43315 be plain and the other side curved for magnification. Additional clip-on mirrors may be incorporated as desired. Moreover, the entire mirror head can be made removable, for example by a press-fit socket to enable other mir-rors to be fitted, or a damaged one to be replaced.
To maintain the mirror in any set position, friction means may be provided. As an alternative to the lamp bulbs being fixed on the arm, they can be secured to the mirror and move with it. As an alternative to position-ing a pair of bulbs in the region of the mirror, it is envisaged that a single bulb could be positioned on the housing and a series of optic fibres be arranged to conduct the light to the region of the mirror.
Claims (11)
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. A mirror construction comprising an elongate body, and an elongate arm, one end of which carries a mirror and the other end of which is pivotally connected to the body for swinging between an operating position in which the arm extends away from the body, with the mirror at a distance from the body, and a storage position in which the arm extends lengthways of the body, being housed within an open recess formed in the body.
2. A mirror construction as claimed in Claim 1 in which the arm includes first and second elongate sections which are pivotally connected together end to end, and the end of the first elongate section remote from the pivotal con-nection to the second elongate section constitutes the said other end of the arm, and, in the storage position, the first section is housed within the said open recess, with the pivotal connection to the second section adjacent one end of the body, and the second section being housed in a second open recess formed in the body, the two recesses opening in opposite directions.
3. A mirror construction as claimed in Claim 1 in which the or each open recess is formed as an open channel in the body.
4. A mirror construction as claimed in Claim 3 in which a lamp is mounted at the said one end of the arm, and the body affords two elongate com-partments for voltaic cells to provide power for the lamp, the compartments lying parallel to and one on each side of the channel or channels.
5. A mirror construction as claimed in Claim 1, in which the mirror is connected by an angleable connection to the said one end of the arm.
6. A mirror construction as claimed in Claim 5 in which the angleable connection permits tilting of the mirror relative to the arm about an axis which lies generally transverse to the length of the arm, the construction also including a longitudinally movable adjustment member on the arm adjacent the mirror, and a flexible connection connecting the mirror to the adjustment member, which flexible connection, in one position of the mirror, extends lengthways of the arm and is offset from the said axis, and is capable of trans-mitting longitudinal movements of the adjustment member to the mirror to tilt the mirror about the said axis.
7. A mirror construction as claimed in Claim 5 in which the angleable connection allows tilting of the mirror about two axes lying generally at right angles.
8. A mirror construction as claimed in Claim 7 in which the angleable connection includes a bracket which is connected to the said one end of the arm for pivoting about one of said axes, the mirror being connected to the bracket for pivoting relative to the bracket about the other of said axes.
9. A mirror construction as claimed in Claim 8 in which the said one axis extends generally transversely of the arm, and is offset from the said other axis.
10. A mirror construction as claimed in Claim 9 in which an elongate ad-justment element is connected to the mirror by a flexible connection, the axis of the adjustment element being substantially aligned with the said other axis in one position of the mirror, and the flexible connection being capable of transmitting axial movements of the adjustment element to the mirror to produce tilting of the mirror about the said one axis, and capable of trans-mitting rotational movements of the adjustment element to the mirror to pro-duce tilting of the mirror about the said other axis.
11. A mirror construction as claimed in Claim 6 or Claim 10 in which the flexible connection comprises an open-coil helical spring.
