Abstract
ABSTRACT OF DISCLOSURE
A bracket is disclosed for supporting at least one manual control beside an operator's chair near the forward end of the chair to permit a convenient manual operation of said control for an operator seated on the chair, at least one arm rest being mounted on the bracket to form a support for the operator's forearm adjacent to said control.
A bracket is disclosed for supporting at least one manual control beside an operator's chair near the forward end of the chair to permit a convenient manual operation of said control for an operator seated on the chair, at least one arm rest being mounted on the bracket to form a support for the operator's forearm adjacent to said control.
Description
~04'7g~0 l'he present inv~ntion re:Lates to u bracket for iupportin~ at least one manual control besi~e an operator's chalr near th~ forward end of the chair to permit a convenlen~ manual operatlon of said control for an operator seated on the chalr and to an operator~s chair incorporatlng the sams.
The invention ls especially intended to be utiliæed in various types of special vehicles and worklng machines where the manual control or controls mounted on the bracket may gerve ag commands for the vehicles or machines or any equipment provided thereon. The manual controls usually consist of hydraulic valves although they may also b~ of any other suitable type. For instance, they may consist of electrical switches.
In practice, the operation of said control, or controls, may often cause fatigue to an operator due to muscular exertion felt in his arms.
This fact is experienced especially by operators of vehicles or machines in whlch strong vibrations or heavy shocks appsar9 which is the case, for instance, in respsct of vshlclss or machinss ussd in forsstry or for agricultural purposss.
An ob~ect of ths invsntion is to provide an arrangement which effectively facilitates the operation of the manual controls, while simultaneously eliminating the risk for physical in~ury due to muscular exertion and, in addition thereto, also reducss ths risk for unintentional falss operation of ths controls as a consequence of heavy shocks or strong vibrations.
In accordance with the invsntion there is provided a device for use in association with a chair having a back and seat for the operator of a machine whsrsin said machine is sub~sct to vibrations and/or shock loads and has at lsas~ one control band manipulated by said operator whils ssated on said chair, said device comprising~
(a) a bracket for mounting said control adjacsnt a forward ; portion of the ~eat of said chair for sasy hand manipulation of ths control ': ~
~)4~0 by the operator wh:LLe seated on ~uld chair; and (b3 an elongate arm rest assembly secured ad;lacent one end thereof to said bracket 90 as to be cant$1evered therefrom to extènd in a direction away Erom the control toward the back of sald chalr wllen associated therewith for supportlng the operator'~ forearm durlng hand manipulation of the control.
The arm rest may be adjustably mounted on the bracket to lA- :
.
~ 7~1~
permit an ad~us~ment Lr~ vlew o~ th0 in~JLvldual anatoMy of eacn opera-tor. The arm rest may be resiLiently rnoun~ed on the ~racket in order to attenuate vibrations or shocks appearing in the vehicle or the machine.
According to a preferred embodirnent of the invention the arm rest may have the general shape of a substantially rectangular plate carried by a holder mounted on the bracket. Said plate may be arranged for longitudinal displacement on the holder which~ in its turn, may be adjustable in a substantially vertical direction.
On its lower side~ the arm rest plate may be provided with a guide socket for receiving a portion of the holder displaceably therein. Said socket may suitably be located at a shorter distance from one longitudinal edge of the plate than from the opposite edge to allow the plate to be mounted in two different7 laterally displaced positions on the holder.
On its upper side~ the arm rest may have a comparatively soft upholstering to permit a certain degree of movement of the fore-arm of the operator without any change in the contact surface with the arm rest.
Below the invention will be described in further detail~
reference being had to the accompanying diagrammatic drawings~ in which:- ;
Figure 1 is a perspective view of an operator s chair and a bracket which serves to support a pair of manual controls and has a pair of arm rests mounted thereon adjacent to said controls;
Figure 2 is a partially exploded perspective view of the bracket and the arm rests; and Flgure 3 is a detailed view~ on an enlarged scale~ showing an arm rest and its appurtenant holder as viewed at an inclination ~-from below.

Figure 2 is a partially exploded perspective view of the bracket and the arm rests; and Flgure 3 is a detailed view~ on an enlarged scale~ showing an arm rest and its appurtenant holder as viewed at an inclination ~-from below.
In the drawings reference numeral lO designates a chair
2 -~ 4'7~310 mounted on a suppoI-t-lng struc-ture 11 which may be arranged to carry the chair reslliently and longitudinally displaceable thereon, The supporting structure 11 is mounted on a base portion 12 of a bracket generally designated 13 which, ln its turn, is intended to be mounted on a suitable base, such as on the chassis of a truck or other ve-hicle or machine.
The bracket 13 includes a steel tube frame 14 having upstanding lateral portions 15 which extend substantially at right angles from the base portion of the bracket, At their upper ends, said lateral portions 1~ of frame lL~ are provided with support rings 16 for sup-porting a hydraulic manual control valve 17 at each side of the seat of the chair adjacent to and at some distance above the front end of the seat. Reference numeral 18 designates two substantially rectangular plates forming arm rests which are mounted on bracket 13 by means of holders 19. Each holder 19 is formed by an angularly bent flat iron which may be inserted with its one leg into a socket 20 connected to the respective support ring 16 and locked in the desired vertical - ~
position by means of a locking screw 21. On the other leg of holder 19~ the corresponding arm rest 18 may be mounted by means of a socket 22 provided on the lower side of the arm rest. The two arm rests 18 may be locked in desired positions on holders 19 by means of locking screws 23 passing through threaded bores in the walls of sockets 22.
As best can be seen from Figure 3~ each socket 22 is located at a shorter distancè from one longitudinal edge of the respective arm rest 18 than from the opposite longitudinal edge of said arm res~.
Hereby each arm rest 18 may be mounted in two different lateral po-sitions on holders 19. On their upper sides the arm rests 18 may .
be provided with a comparatively soft and preferably rather thick : : :
upholstering. The two holders 19 may be resiliently deflectable.
