Description
- (Not Applicable)
- (Not Applicable)
- The present invention relates to sanding devices and, more particularly, to a floating head sanding device useful to provide precision finishes to a product surface.
- A resilient sanding mechanism is provided for sanding the contours of a working surface, such as an aircraft body. The mechanism comprises an elongate frame having a frame axis, a sander mechanism pivotally engaged to the frame and having a sanding surface disposed distal to the frame. A resilient biasing apparatus is engageable to the sander mechanism and to the frame, for biasing the sander mechanism sanding surface in a predetermined orientation with respect to the frame axis.
- In the presently preferred embodiment the resilient biasing apparatus comprises a plurality of springs operative to bias the sanding surface to an orientation substantially normal to the frame axis. The springs function to urge the sanding surface against the working surface as the sanding surface traverses the working surface.
- The frame may be formed to be resiliently compressible along the length thereof, to urge the sanding surface upwardly against the contours of the working surface. The sanding mechanism may be belt mounted, whereupon the upward force upon the sanding mechanism is provided by the engagement of the frame to a belt mounted frame receiving member.
- In another embodiment the frame extends to the ground and may be provided with a pivotal frame support member operative to provide ground support to the sanding mechanism.
- The frame may be constructed to be resiliently compressible along the length thereof, to mitigate translation of vibration to the worker, and/or to provide a resilient force urging the sander upwardly as it is placed into compression against the working surface.
- The sanding mechanism may further be provided with a plurality of handles engageable to the frame at a plurality of locations along the frame. The handles may further be constructed to be rotatably engageable to the frame to facilitate convenient arrangement thereof.
- Sanders have a wide variety of applications extending from everyday home use to aerospace applications for composite technologies, or for use on fiberglass boat holes. Particular types of products and materials may require more of a precision finish to achieve optimum functionality. The size and shape of the product may also dictate types of sanders, the type of finish, etc. Sanding techniques may also vary in accordance with the nature of the product, materials or desired finish.
- In some cases large products may require the use of automated hand sanders to achieve the desired finish. While the equipment to perform such operations is readily available, the human operation of such equipment, particularly over extended periods, can lead to injuries or disabilities to workers operating such equipment. Where, for example, the surface to be sanded is above the worker, the worker will typically hold the sander above his chest or head, supporting the weight of the sander while pressing the sander against the work surface. The position weight and vibration of the sander can stress and pressure the worker's body in a manner to cause injury over periods of such sanding activity. As many companies recognize a safe and comfortable work environment is not only in the interest of workers, but also in the interest of companies who rely upon those workers to perform skilled or touch work.
- Accordingly, there exists a need to devise equipment to facilitate the extended operation of sanders without jeopardizing the health of workers or detracting from their productivity. That need is particularly acute where large product areas are to be sanded, from positions where manual support of the sander may be stressful.
- FIG. 1 is a perspective view showing one embodiment of the invention in use against the underside of a working surface;
- FIG. 2 illustrates a belt supported embodiment of the invention; and
- FIG. 3 illustrates a ground supported embodiment of the invention.
- The present invention is described in connection with the illustrated embodiment. As such the structural features and functional attributes of the invention are set forth in connection with the particular construction of sander mechanism, sander biasing apparatus, sander pivotal support apparatus, and sander resilient axial support apparatus. However, as will be recognized by those skilled in the art, the invention may have application to a variety of other types of sander mechanisms, sander support apparatus and apparatus for maintaining a desired orientation of the sander mechanism sanding surface. Where, for example, the surface to be sanded is contoured in an irregular manner, or accessible only from restricted locations, modifications to orienting and supporting components of the invention are anticipated, within the broader aspects of the invention illustrated and described below.
- FIG. 1 illustrates an embodiment of the
sanding mechanism 10 includingframe 11, andsanding mechanism 15, pivotally mounted toframe post 13 and sanderpivotal support apparatus 17. It is anticipated that theframe 11 may be any of a variety of types of elongate members, such as a metallic rod or elongated member of other substantially rigid material. Thesander 15 may be implemented as any of a variety of oscillating, reciprocating or vibrating sanders having asanding surface 19 adapted for frictional engagement to the workingsurface 21, i.e., thesander 19 will sand thesurface 21 when the sanding mechanism is urged against the workingsurface 21. Thesanding surface 19 is disposed on thesander 15, opposite the engagement ofsander 15 to post 13 andpivotal support apparatus 17. - The
pivotal support apparatus 17 incorporates asupport surface 23, which may be directly engageable to thesander 15, or to a sander support mechanism, such assupport mechanism 25, adapted to securley engage and support thesander 15. Power to thesander 15 may be provided by means such ascable 27.Vacuum line 29 may be provided to vacuum particles separated by action of thesanding surface 19 against the workingsurface 21. - The
sanding mechanism 10 may be directed towards the workingsurface 21 by means of manual manipulation ofhandle apparatus frame 11, and rotatable thereabout by means of retainingfasteners 35 a, b, c, extendable through apertures, such as 37 a, b, to effectively clamp the handle mechanism at axially spaced locations along theframe 11. - The
post 13 may be rigidly secured to afirst end portion 37 offrame 11, e.g., by means of screw attachment. Alternatively, thepost 13 may be supported by a resilient mechanism (not shown), such as a spring that reciprocates withinframe 11, alongframe axis 33. In such an embodiment, thepost 13, and any supporting structure, is urged outwardly from the frame, and compressible into the frame. - The
sander mechanism 15, including such sander support apparatus as may be present, is preferably biased such that the sanding surface is urged towards a predetermined orientation with respect to theframe axis 33. Resilientsander biasing apparatus 39 a, b, c, which are implemented as tension springs in the illustrated embodiment, are secured to the sander support mechanism atlocations 41 a, b, c, respectively. Opposing ends of thesprings 39 a, b, c, are engageable to theframe 11 viaframe coupling member 43, which is secured to aframe 11. Thecoupling member 43 is translatable about theframe 11 along theframe axis 33. Thecoupling member 43 may be disposed at a selected location alongframe 11 to maintain the desired bias and orientation ofsanding surface 19. As the coupling member is drawn downwardly along theframe 11, the biasing force acting on thesanding surface 19 will become greater (stiffer), requiring more force to overcome the predetermined orientation ofsanding surface 19. In the presently preferred embodiment thesanding surface 19 is biased to an orientation substantially perpendicular to theframe access 33. Deviation from that orientation, e.g., by moving the sander along the contours of the work surface, generates a reactionary force which urges the sanding surface into engagement with the working surface. Consequently, the user need not manually manipulate the angular orientation of the sander in order to facilitate the force acting to urge the sander against the working surface. The user may simply urge the sanding surface upwardly against the working surface, and move the sanding surface along the working surface, e.g., in an arcuate motion. The angular orientation of the sanding surface with respect to the working surface is effected by pivotal mounting of the sander and the resilient springs urging the sander to return to its normal biased position. - FIG. 2 illustrates an embodiment of the invention wherein the sander mechanism is floor supported. As shown therein the
frame 11 extends from thesander 15 tofloor mount 43, which rests on thefloor 45. Theframe 11 includes frame extenders orsupport posts post coupler 51. In the presently preferred embodiment thepost members coupler 51 to permit resilient, reciprocating travel therebetween, alongpost axis 33. Such resilient engagement sers to dampen vibration from the sander, and to facilitate maintenance of an upward force to keep the sanding surface in contact with the working surface. The framelower portion 53 is secured tofloor mount 43. - FIG. 3 illustrates a belt mounted embodiment of the sanding mechanism. The upper portion of the sanding mechanism is preferably constructed as indicated above. However, the lower portion of the
frame 11 includescylindrical portions support 47.Support members user 20 to maintain the sandingsurface 19 against the working surface, and mitigate the translation of vibration to the user. - As shown in FIG. 3 the
user 10 may be provided with abelt 60, which may be formed of elastomeric material, which is secured to frame receivingmember 65 viafastener 63 engageable toaperture 65. Theframe receiving member 65 may be provided withframe receiving collar 61 adapted to receive and supportpost member 57. - As described in connection with the previous embodiments, the embodiment of FIG. 3 functions to bias the
sander surface 19 into a predetermined position, such that it will urge the sanding surface into contact with the working surface, as the sanding surface is displaced from its normal position to follow the contours of the work surface.
