Description
- The present invention relates to a sander. More particularly, the present invention relates to an adjustable sander that is suitable for use on both flat and curved surfaces, such as the sander described in
DE 19534014 A1 . - Sanders are well known tools. They are typically used in automotive or manufacturing applications wherein there is a need to obtain a smooth surface. Sanding is often applied to flat substrates. A handheld sander having a flat sanding surface may easily sand such flat substrates. However, often times there is a need to sand an object with a curved substrate. In such instances, a sander with a flat sanding surface may prove to be inadequate and even burdensome.
- To address this problem, it is known to have a sander with a flexible base and sanding surface. The sanding surfaces of such sanders may contour to the substrate that is being sanded. However, such sanders require the operator to apply constant and even pressure so that the flexible sanding surface remains in contact with the curves of substrate. It would be advantageous to have a sander that is adjustable wherein the operator can select the contour (convexity or concavity) of the base and have said contour position maintained without further effort from the operator.
- The present invention addresses one or more of the aforementioned problems by problems by providing an adjustable sander having a body and a flexible base. The flexible base includes a first end and a second end spaced apart from one another. The first end and second end are each pivotally attached to the body. The flexible base is configured to move between a concave configuration, a neutral configuration, and a convex configuration relative to the body. The adjustable sander further includes a removable sanding surface affixed to a surface of the flexible base that is distal from the body. The adjustable sander also includes a locking mechanism configured to selectively hold the flexible base in a desired concave, neutral or convex configuration. The locking mechanism is characterized in that it includes an axial having a head and a shaft having a series of shaft notches. The locking mechanism further includes a selector having an operator surface and a holder. The operator surface is accessible from outside the body. The holder includes an engagement surface having at least one holder notch configured to selectively engage at least one of the shaft notches. The selector is selectively movable between an engaged position wherein the at least one holder notch is engaged to one of the shaft notches, and a disengaged position, wherein the at least one holder notch is disengaged from the shaft notches.

Thebody 12 may be a single housing or it may be of a two-part clam shell design. Theflexible base 14 has afirst end 16 and asecond end 18 spaced apart from one another. Thefirst end 16 andsecond end 18 is each pivotally attached to thebody 12, and wherein theflexible base 14 is configured to move between a concave configuration, a neutral configuration, and a convex configuration relative to thebody 12. Theadjustable sander 10 also includes aremovable sanding surface 20 affixed to a surface of theflexible base 14 that is distal from thebody 12. Theadjustable sander 10 also includes alocking mechanism 22 that is configured to selectively hold theflexible base 14 in a desired concave, neutral or convex configuration. - The
locking mechanism 22 includes an axial 24. The axial includes ahead 26 and ashaft 28, having a series ofshaft notches 30. Theshaft notches 30 may be positioned on a single side of theshaft 28; on multiple sides of theshaft 28; or may be a screw-like surface that encompasses a circumference of theshaft 28. Thelocking mechanism 22 includes asleeve 32 that is positioned around theshaft 28. Also included in the locking mechanism is aselector 34. As shown inFigure 1 , theselector 34 may be athumb slider 78. Alternatively, as shown inFigure 6 , theselector 34 may bewinged slider 80. Theselector 34 includes anoperator surface 38 and aholder 38. Those skilled in the art will recognize that theselector 34 andholder 38 may be a single integrated piece or it may be multiple interconnected pieces. Theoperator surface 36 is accessible from outside thebody 12 and theholder 38 includes an engagement surface 40 having at least oneholder notch 42 that is configured to selectively engage at least one of theshaft notches 30. Theselector 34 is movable between an engaged position wherein the at least oneholder notch 42 is engaged to one of theshaft notches 30, and a disengaged position, wherein the at least oneholder notch 42 is disengaged from theshaft notches 30. In the first embodiment, theholder 38 is substantially U-shaped 44. It includes twotines 46 each having an engagement surface 40 with at least oneholder notch 42 thereon. The twotines 46 of theholder 38 are spaced apart such that they can accommodate theshaft 28 therebetween. - In a preferred embodiment, the
sleeve 32 of thelocking mechanism 22 may further define awindow 58. The engagement surface 40 of theholder 38 may engage theshaft notches 30 through saidwindow 58. Thesleeve 32 may also include one or more holder guides 110. In this first embodiment, the holder guides 110 may be positioned immediatelyadjacent window 34. As best shown inFigure 4a , the holder guides 110 are configured to receive and guide thetines 46 into their engagement position. Theholder 38 is configured move horizontally between its engagement and disengagement positions. As theholder 38 is moved into its engagement position, the holder guides 110 may also prevent perpendicular axial movement ofholder 38. Thus, the holder guides 110 may assist in securing the selector in its engaged position. Those skilled in the art will recognize that thesleeve 32 may define a second window 62 and include another set of holder guides (not shown) positioned respectively on thesleeve 32 opposite thefirst window 58 andholder guide 110. - The locking mechanism may further include a
detent 82 that is biased by aspring 84. Thedetent 82 andspring 84 are configured to prevent unwanted movement of theselector 34. In a preferred embodiment, thedetent 82 andspring 84 are positioned inside thebody 12. In a preferable embodiment, thedetent 82 anddetent spring 84, may be positioned within adetent housing 85 within thebody 12. Thespring 84 biases thedetent 82 toward theholder 38. Thedetent 82 is configured to engage detent receiving surfaces 86, which are defined by theholder 38. As theselector 34 is moved between the engaged position and the disengaged position, thedetent 82 is biased by thespring 84 toward thedetent receiving surface 86. Once engaged to the detent receiving surface, the spring biased detent holds theselector 34 in the desired position, thereby preventing unwanted movement. When the operator desires to move theselector 34 to its other position, she must apply enough force so that thedetent 82 presses back against thespring 84. When the selector reaches its desired position, thespring 84 biases thedetent 82 into anotherdetent receiving surface 86. - In a preferred embodiment, the
locking mechanism 22 further includes aspring 88 positioned around theshaft 28.Spring 88 is configured to be selectively compressed between thehead 26 of theshaft 28 and thesleeve 32. More specifically, thatspring 88 may be selectively compressed between thehead 26 of theshaft 28 andwings 33 on thesleeve 32. In operation,spring 88 may bias theflexible base 14 from a convex configuration towards a neutral configuration. -
Figures 6-10 disclose a second embodiment of theadjustable sander 10. In this embodiment, thelocking mechanism 22 differs in that theoperator surface 36 of theselector 34 is awinged slider 80. Additionally, in this second embodiment, theholder 38 is aplate 48.Plate 48 defines anopening 50 having alarge end 52 and asmall end 54. Theopening 50 is sized and configured to accommodate theshaft 28 therethrough. Thelarge end 52 of theopening 50 is much larger than theshaft 28 such that an internal edge 56 of theopening 50 cannot engage theshaft notches 30. Conversely, thesmall end 54 of theopening 50 is only slightly larger than theshaft 28 such that the internal edge 56 of theopening 50, which functions as theholder notch 42 can engage theshaft notches 30. In a preferable embodiment, theshaft 28 includes two sets ofshaft notches 30. The internal edge 56 of theopening 50 on thesmall end 54 is configured to engage both sets ofshaft notches 30. -
