Abstract
RETRACTABLE TRUCK MIRROR
Abstract of the Disclosure A truck mirror comprising a U-shaped support on which a mirror is pivotally mounted. The ends of arms of the support are pivoted to vertically spaced brackets that are adapted to be mounted on the truck. Pivot means are provided between the ends of the support arms and the brack-ets and comprise two members of low friction material fixed to the arms. The pivot members define a chamber in which an axially movable member is positioned. One of the pivot members has axially extending circumferentially spaced grooves therein and a movable member has complementary pro-jections. The movable member is yieldingly urged toward the member having the grooves such that the mirror is held in angularly adjusted position but may be readily moved to a new angular position by manual manipulation.

Description
~7~3 This invention relates to truck mirrors and ``~
particularly to adjustable truck mirrors.
Background o~ the Invenkion In truck mirrors~ which are required by law ~n - 5 many governmental jurisdictions, it i5 common and desir~
able to provide for initial ad~ustment of the mirror to ` ;~
accommodate the driver and at the same time to provide a construction wherein the mirror can be readily retracted or moved out Or its projected position for clearance and thereafter readily moved back to its adJusted position without the use of tools. Various designs have been here-tofore proposed which required compllcated construotions.
Another problem with respect to the such constructions has `;
been that of corrosion after prolonged use.
In the United States Patent No. 3,784,149, issued January 8, 1974, having a common assignee with the present application, there is disclosed and claimed a truck -mirror wherein the mirror is supported on a U-shaped sup-port. The ends of the arms of the support are pivoted to vertically spaced brackets that are adapted to be mounted - 20 on the truck. Pivot means are provided between the ends of the support arms and the brackets and comprise two mem~
bers of low friction material. One of the members has axially extending circumferentially spaced grooves therein and the other of the members has complementary projections.
The members are yieldingly urged toward one another such -that the mirror is held in angularly adjusted position but may be readily moved to a new angular position by manual ~ -manipulation. Such a ccnstruction has been found to be `~ very effective but may be obJectionable in that it has an ~ 30 exposed external spring.

ported at its ends on a U-shaped support 12 compr-ising ~-spaced arms 13 connected by vertical portion 14. Braclc-ets 15 are rixed at vertically spaced points on the door 10. Each bracket comprises a base 16 and angularly rela-ted legs 17 that have flattened erlds 18 t~at overlap one another. ~e ends of the arms 13 are flattened as at 19 Pivot means 20 are provided between the braeket arms 17, 18 and the support arms 13 at each bracket or at ~

in, the axes of whieh are inelined to the axis of the mem- ~:~
ber 21. Pivot member 22 is generally eylindrieal and in- :
eludes a generally eylindrieal wall 28 and a base 29. Mov- :~
able member 23 is generally eylindrical and telescopes with-in wall 28. The wall 24 of pivot member 21 telescopes with-in the wall 28 of pivot member 22 and abuts a shoulder 30.

eonieal and generally eomplementary to surface 26 and is formed with cireumferentially spaeed projeetions 32 that are eomplementary to the grooves 27 and have axes inelined : with respeet to the axis of the member 22. The configura-tion of the grooves 27 and projeetions 32 is generally U-shaped but is sueh that when the grooves and projeetions ~ ~ :

Pivot member 21 is formed with a transverse groove 35 into which the flattened portion 19 of arm 13 extends. Similarly, pivot member 22 is formed with trans~
verse groove 36 into which the flattened portion 18 of the leg 17 extends. A bolt 37 having a head 38 extends through ~`~
openings 39, L~o, 41 in members 2~, 23, 22 and a nut 42 is threaded on the end of the bolt 37 . Washers 43, 44 are interposed bet~een head 38 and leg 13 and between the nut ;~ 15 37 and leg 15. A compression sprin~ 45 is interposed be~
tween wall 2 and movable member 23 thereby providing a compressive force such that the movable member 23 and pivot member 21, 22 are urged axially toward one another. ~;
llhen assembled~ the manual manipulation of the support 12 causes the pivot member 21 to be rotated angu-larly with respect to the support member 22. During this movement, axial compression of the spring ~5 is achieved so that grooves 27 move successively into engagement with ;-projections 32. When it is desired to re-adjust the mirror for clearance or ~or use by drivers of different physical ;~
proportions, the support 12 is again grasped to move the mirror to the desired position. In any position, the mir- -ror is firmly held in its adjusted position.
The pivot members 21, 22 are preferably made of 3 a lo~l friction material such as plastic~ A satisfactory material comprises nylon.
