Description

July 11, 1961 R. .1. WALTERS BACK-UP PAD AND ABRASIVE SHEET Filed Aug. 7, 1959 B ..IO 5 E w A is? INVENTOR. ROY J. WALTERS BY W MW Unite This invention relates in general to a device for finishing or working the surfaces of materials, and more particularly to an abrading device, and still more particularly to a combination back-up pad and detachable abrasive sheet.

Heretofore, abrasive sheets which were detachable from a holder had one main disadvantage in that too much time was consumed in effecting replacement of abrasive sheets.

Accordingly, it is an object of the present invention to provide an improved detachable abrasive sheet that may be quickly and easily replaced without the use of special tools.

Another object of this invention is in the provision of a combination back-up pad and abrasive sheet adapted to be mounted on a holder, wherein the abrasive sheet may be easily applied and locked to the back-up pad, and easily removed therefrom.

Still another object of this invention resides in the provision of a combination back-up pad and abrasive sheet including a snap fastener having male and female parts, wherein one of the parts is secured to the abrasive sheet and the other part is secured to the back-up pad, thereby permitting easy mounting and dismounting of the abrasive sheet on the back-up pad.

A further object of this invention is in the provision of a combination back-up pad and abrasive sheet including a snap fastener having male and female parts, wherein one of the parts is secured to the abrasive sheet and the other part is secured to the back-up pad, and means is provided on the back-up pad for engagement with the abutting surface of the abrasive sheet to prevent relative movement between the abrasive sheet and back-up pad.

A still further object of this invention is to provide a combination disc-shaped back-up pad and abrasive disc having means for permitting easy application of the abrasive disc to the back-up pad and assuring positive centering and locking action, wherein no protrusions will exist on the abrasive side of the disc.

A further object of this invention is in the provision of a combination abrasive disc and disc-shaped resilient back-up pad including a snap fastener having coacting male and female parts, wherein one of the parts is secured to the non-abrasive side of the abrasive disc and the other part is recessed from the outer surface of the back-up pad, and a layer of tacky substance is provided on the outer face of the back-up pad for engagement with the non-abrasive side of the abrasive disc to prevent relative movement between the abrasive disc and back-up pad.

A still further object of this invention is to provide a combination abrasive sheet and back-up pad including a plurality of snap fasteners for detachably securing the abrasive sheet to the back-up pad, whereby easy mounting and dismounting of the abrasive sheet on the back-up pad is obtained without the use of any special tools.

Other objects, features, and advantages of the invention will be apparent from the following detailed disclosure, taken in conjunction with the accompanying sheet of drawings, wherein like reference numerals refer to like parts, in which:

FIG. 1 is a perspective view of the invention illustrating the abrasive sheet removed from the back-up pad, and the back-up pad is mounted on a holder;

FIG. 2 is an axial sectional view taken through the em- Sates Patent f bodiment of FIG. 1 and illustrating the abrasive sheet in r 2,991,596 Patented July 11, 1961 removed position in solid lines and in mounted position in dotted lines;

FIG. 3 is a view similar to FIG. 2, and illustrating the reversal of positioning of snap fastener parts wherein the female part is secured to the abrasive sheet and the male part is secured to tthe back-up pad; and

FIG. 4 is a perspective view of an orbital sander and illustrating the application of the present invention thereto.

Referring now to the drawings, and particularly to FIGS. 1 and 2, the present invention includes generally a resilient back-up pad 10 and an abrasive sheet 11. In this embodiment, the back-up pad and abrasive sheet are disc-shaped, and the back-up pad is constructed to be mounted on a rotatively driven holder or mandrel, generally designated by the numeral 12.

The holder 12 includes a head 13 and a spindle 14, wherein the spindle is adapted to be connected to a rotative source of power, and the head is adapted to have the back-up pad 10 attached thereto. The head 13 also includes a diametrically reduced portion 15 having an inwardly spaced annular groove 16 defining an annular retaining flange 17 spaced outwardly from a backing surface 18 on the head.

The back-up pad 10 is preferably made of rubber, but may be made of any resilient material, and includes an annular enlarged portion 19 having an inwardly projecting radial lip 20 for engagement over the flange 17 of the holder head 13 by being received in the annular groove 16 thereof. Thus, the back-up pad 10 may be removed from the holder 12 or mounted thereon by means of manipulating the back-up lip 20 relative to the holder flange 17.

As seen most clearly in FIG. 2, the abrasive disc 11 includes a sheet of material 21 having abrasive particles 22 secured to the outer side and a smooth surface 23 on the inner side. The sheet of material 21 and the type of abrasive material 22 secured thereon may be of any known type suitable to the Particular type of operation of the user. For example, the sheet of material may be paper, plastic, fabric, steel, or any other suitable material.

In order to detachably mount the abrasive disc 11 to the back-up pad 10, a snap fastener including a male part '24 secured to the smooth side 23 of the abrasive disc 11 and a female part 25 secured to the back-up pad 10 may be provided. The male part 24 may be secured to the abrasive disc 11 if the disc is steel by welding or soldering, or if the disc is of paper or other stock by a suitable adhesive. Likewise, the female part 25 may be secured to the resilient back-up pad 10 in any suitable manner. Depending on the type of use required for the abrasive sheet and back-up pad, the snap fastener may be constructed of steel, rubber, plastic, or any other suitable material.

As noted in FIG. 2, the female part 22 of the snap fastener is recessed from the outer surface of the back-up pad 10, and a centrally slightly dish-shaped portion 26 is provided in the outer surface of the back-up pad, whereby attachment of the male part 24 to the female part 25 assures the absence of protrusions from the outer abrasive side of the disc 11.

In order to prevent relative movement between the abrasive disc 11 and the back-up pad 10, or relative rotation between these parts, a layer of tacky or adhesive material 27 is provided on the outer surface of the backup pad 10 for engagement with the smooth surface 23 of the abrasive disc 11. Inasmuch as the snap fastener parts are centrally mounted on the back-up pad and abrasive disc, positive centering and locking action of the abrasive disc tothe back-up pad is accomplished, and it will be readily appreciated that replacement of the abrasive disc can be accomplished with ease.

The embodiment of FIG. 3 differs from the embodiment of FIGS. 1 and 2 only in that the male and female parts of the snap fastener are reversed in position, Wherein the male part 28 issecured to the back-up pad 10, and the female part 29 is secured to the smooth side 23 of the abrasive disc 11.

The combination abrasive sheet and back-up pad unit of the present invention may also be utilized in connection with orbital sanders, and an orbital sander 30 is illustrated in FIG. 4.

The orbital sander 30 includes a main housing 31 having a handle 32 attached thereto, and a driving plate 33. Suitably secured to the driving plate 33 is a rubber backup pad 34, like the back-up pad of the other embodiments except rectangular in shape. A layer of tacky substance 35 is provided on the outer surface of the backup pad 34, and female parts 36 of snap fasteners are secured in recessed fashion at the four corners of the backup pad. In this instance, the abrasive sheet 37 is rectangular in shape, but may be constructed of the same materials as the abrasive disc 11 of FIGS. 1 to 3. A plurality of male parts 38 are suitably fastened to the smooth side of the abrasive sheet 37 and in alignment with the female fasteners 36 on the back-up pad 34, whereby snapping of each male part 38 into its corresponding female part 36 will attach the abrasive sheet 37 to the back-up pad of the orbital sander. The tacky substance 35 will engage the smooth surface of the abrasive sheet 37 and inhibit relative movement between the abrasive sheet and back-up pad. As in the embodiments of FIGS. 1 to 3, the abrasive sheet 37 may also be easily removed and replaced with a new sheet by simply unsnapping the male parts from the female pants.

It will be understood that modifications and variations may be effected without departing from the scope of the novel concepts of the present invention, but it is understood that this application is to be limited only by the scope of the appended claims.
