Also, the terminology used herein is for the purpose of description and not of limitation.
DET~ILED DESCRIPTION
Referring first to Figures 1-3, a padlock of known design is shown as having a cylindrical body 10 with a front end face 11 where a rotatable ~nob 12 is located and a back end face 13. The knob 12 operates a combination lock mechanism inside the body of the padlock in the usual manner. At the top, the padlock has the usual rigid shackle S of inverted U-shape which is down (as shown) when the lock is closed and is displaceable upward with respect to the padlock body when the lock is open. When the lock is open, the padlock body may be rotated about one vertical leg of the shackle, or vice versa.
The cover i8 a one-piece molded body of polypropylene or other suitable plastic material having an annular side wall 14 which is heart-shaped on the outside and on the inside for most of its length axially has a cylindrical surface 15 (Figure
3) which is complementary to the cylindrical padlock body 10 to snugly surround the latter.
At the front end the cover 14 has a radially inwardly extending lip 16 with an uninterrupted, generally heart-shaped inner edge 17 which throughout its extent has a substantial radial spacing from the knob 12 of the padlock. Consequently, the front end lip 16 on the cover does not interfere with the user's fingers when he or she grasps the knob and turns it to open the combination lock. The front end lip 16 engages the front ~ace 11 of the padlock body a short distance inward from its periphery, as shown in Figure 3.
:~2~4~3 At the top the cover is formed with two parallel slots 18 and 19 for receiving the opposite ~traight legs of the shackle S. Each of these slots is open at the back end of the cover, so that the cover can be slid onto the padlock from front-to-back. The slots are wide enough that the padlock body can be turned with respect to the shackle, or vice versa, after the lock is opened.
At its back end the cover has a generally circular opening 20 which is aligned with its cylindrical inside surface 15. Several short flexible and resilient elements 21 project radially inward at circumferentially spaced locations around this opening. These elements engage the back end face 13 of the padlock body to hold the cover in place on the padlock body.
The cover may be inserted on the padlock body from front-to-back. The deformable elements 21 around the back opening 20 in the cover slide across the cylindrical body 10 of the padlock and when they reach the back end face 13 of the padlock body they snap inward to engage it. The padlock body is snugly received from front to back between the front lip 16 and the back projections 21 on the cover, and around its cylindrical periphery the padlock body is snugly engaged by the cylindrical inside surface 15 o~ the cover.
As shown in Figures 1 and 2, the distinctive heart shape of the cover tends to take the viewer's attention away from the utilitarian nature of the padlock and what many would consider its stark, ugly appearance. In addtion, tha cover is able to absorb external forces which might damage the padlock or mar its appearance.
Figures 4 and 5 show a second embodiment of the present cover which is applied from back to front on the padlock. Th~
padlock itself is the same as in Figures 1-3. The cover has a cylindrical side wall 114 with a cylindrical inside surface 115 that is complementary to the cylindrical padlo~k body 10. At the right end in Figures 4 and 5, the cover ha inwardly extending, short, flexible and resilient projections 121 which angage the front end face 11 of the padlock body. These ~2'~94~
projections are substantially spaced radially outward from the knob 12 of the padlock. At its left end in Figures 4 and 5 the cover has a radially inwardly extending annular lip 116 with a circular inner edge 117. In the embodiment shown, this lip holds a photograph P flat against the back end face 13 of the padlock body. The cover has longitudinal slots 118 and 119 which are open at the end of the cover where the projections 121 are located. These slots slidably receive the legs of the shackle S on the padlock.
The cover of Figures 4 and 5 is applied to the padlock body by sliding it from back to front over the padlock body.
The deformable projections 121 slids across the cylindrical body of the padlock and then they snap inward when they reach the front end 11 of the padlock body.
Figure 6 shows a third embodiment of the present cover having a cylindrical side wall 214 for snugly encircling the cylindrical body 10 of the padlock along its entire length.
At the front end the cover has an integral annular lip or bead 216 of circular cross-section, the inside of which projects slightly radially inward across the front end face 11 of the padlock body. At its back end the cover has flexible and resilient projsctions 221 like the projections 21 in the embodiment of Figures 1-3. Longitudinal slots 218 and 219 in the top o* the cover are open at it~ back end.
Figure 7 shows a cover having a cylindrical side wall 314 with longitudinal slots 318 and 319 which are open at its back end and inwardly extending, flexible and resilient pro~ections 321 on its back end like the projections 21 in the first embodiment.
Figure 8 ~hows a cover having a cylindrical side wall 414, slots 418 and 419, and flexible "Velcro" strips 30 and 31 on its back end with locking filaments which engage each other when strip 30 overlaps strip 31. Strip 31 may be placed against the back end face of the padlock body and then strip 30 ~ay be pulled taut and appli~d against strip 31 to lock the two strips to each other across the end of the padlock body.

Pigure g shows a cover of two-piece construction having a s~mi-cylindrical upper piece 40 with longitudinal slots 18' and 19' open at its back end and a semi-cylindrical lower piece 41. The two pieces of the cover fit together at longitudinal tongue-and-groove joints 42 and 43 on opposite sides of the cylindrical body of the padlock. The two cover pieces 40 and 41 may be applied to the padlock body from above and below, respectively, to form a unitary annular cover for the padlock.
~igures 10-15 illustrate an alternative embodiment of the present invention.
Referring first to Figures 10 and 11, a padlock of known design is shown as having a cylindrical body 110 with a front end face 411 where a rotatable knob 412 is located and a back end face 413 (Figure 11). The knob 412 operates a combination lock mechanism inside the body of the padlock in the usual manner. At the top the padlock has the usual rigid reciprocable and rotatable shackle S of inverted U-shape which is down (as shown) when the lock is closed and is displaceable upward with respect to the padlock body when the lock is open.
When the lock is op n, *he padlock body may be rotated about one vertical leg 414 of the shackle, or vice versa, from the locking position of Fi~ure 12 to the released position o~ Figure 1~ .
The present cover is a substantially rigid, one-piece molded body of suitable plastic material having a heart-shaped outer side wall 415, and a slightly rounded~convex, front wall 416 extending laterally inward from the outer side wall 415 to a central opening 417. At the top of opening 417, the front wall 416 of the cover presents a downwardly projecting csntral lip 416 which extends directly in ~ront of the front end face 411 of the padlock body. Throughout its extent, the edge of the opening 417 is a substantial distance radially outward ~rom the knob 412 of the padlock so that it does not impede the user's fingers when he or she grasps the knob and turns it.
~' At the top on one side, the outer side wall 415 of the cover presents a circular opening 418 (Figure 15) which rotatably and slidably receives the leg 414 ~f tha padlock shacklet S, as shown in Figures 12 and 14. At the top on the opposite side, the outer side wall 115 of the cover presents a slot 419 which is open at the back of the cover and has a rounded, closed front end. This slot slidably receives the opposite vertical leg 420 of the padlock shackle S. Slot 419 has a chamfered edge 421 on its inner side at the back of the 10cover to facilitate the movement of shackle leg 420 into or out of this slot when the shackle is rotated on its opposite leg 414.
The present cover has a cylindrical inner wall 422 spaced laterally inward from its outer wall 415 and joined to the outer wall by lateral ribs 423 extending between them, as 15shown in Figures 11 and 15. The cylindrical inside surface of inner wall 422 is substantially complementary to the cylindrical side wall of ths padlock body 410 so that the padlock body is slidably but snugly received inside the inner side wall 422 of the cover, as shown in Figure 11. At the lip 416 (Figure 10) 20and on opposite sides of it along the top of the front opening 417, the front wall 416 of the cover extends laterally inward past the inner wall 422 to engage the front of the padlock body.
At the top on one side, the inner side wall 422 has an opening 418a (Figure 15) which is spaced below and vertically 25aligned with, the opening 418 in the outer side wall 415. At the top on the opposite side, the inner side wall 422 has a slot ll9a (Figures 13 and 15) which is spaced below, and vartically aligned with, the slot 419 in the outer side wall 415 and is the same size and shape as the latter, looking down 30on the cover from abova it. The inner side wall opening 4~8a slidably and rotatably receives the padlock shackle leg 414 and the slot 419a slidably passes the opposite leg 420 of the shackle.
With the shackle S in an open postion, the padlock 35410 may be placed inside the present cover by positioning the padlock body behing the cover and sliding the free end of shackls ~t leg 420 through opening 418a in the inner side wall 422 of the cover and then out through the aligned opening 418 in the outer side wall 415 of the cover, and then pushing the rest of the shackle through these openings until the opposite shackle leg 414 is in these openings and the padlock body is seated inside the inner side wall 422 of the cover, with the rotatable knob 412 of the padlock in front of the cover, as shown in Figure 13. The shackle may be rotated from its released or unlocked position ~Figure 14) to the locking position (Figure 12) in which its leg 410 may be pushed into the padlock body for locking engagement with the locking mechanism therein.
When the padlock is closed, the present cover cannot be removed from it because of the engagement of the shackle leg 414 in the openings 418 and 418a in the cover. This effectively prevents any removal of the cover by a person who does not know the combination to open the lock. When the lock is open, the present cover may be mounted on it or removed from it without great difficulty. Ordinarily, however, the owner will keep the cover on as long as the lock is in use since it provides physical protactisn for the lock, as well as identifying it to tha owner and improving its appearance.

At the front end the cover 14 has a radially inwardly extending lip 16 with an uninterrupted, generally heart-shaped inner edge 17 which throughout its extent has a substantial radial spacing from the knob 12 of the padlock. Consequently, the front end lip 16 on the cover does not interfere with the user's fingers when he or she grasps the knob and turns it to open the combination lock. The front end lip 16 engages the front ~ace 11 of the padlock body a short distance inward from its periphery, as shown in Figure 3.
:~2~4~3 At the top the cover is formed with two parallel slots 18 and 19 for receiving the opposite ~traight legs of the shackle S. Each of these slots is open at the back end of the cover, so that the cover can be slid onto the padlock from front-to-back. The slots are wide enough that the padlock body can be turned with respect to the shackle, or vice versa, after the lock is opened.
At its back end the cover has a generally circular opening 20 which is aligned with its cylindrical inside surface 15. Several short flexible and resilient elements 21 project radially inward at circumferentially spaced locations around this opening. These elements engage the back end face 13 of the padlock body to hold the cover in place on the padlock body.
The cover may be inserted on the padlock body from front-to-back. The deformable elements 21 around the back opening 20 in the cover slide across the cylindrical body 10 of the padlock and when they reach the back end face 13 of the padlock body they snap inward to engage it. The padlock body is snugly received from front to back between the front lip 16 and the back projections 21 on the cover, and around its cylindrical periphery the padlock body is snugly engaged by the cylindrical inside surface 15 o~ the cover.
As shown in Figures 1 and 2, the distinctive heart shape of the cover tends to take the viewer's attention away from the utilitarian nature of the padlock and what many would consider its stark, ugly appearance. In addtion, tha cover is able to absorb external forces which might damage the padlock or mar its appearance.
Figures 4 and 5 show a second embodiment of the present cover which is applied from back to front on the padlock. Th~
padlock itself is the same as in Figures 1-3. The cover has a cylindrical side wall 114 with a cylindrical inside surface 115 that is complementary to the cylindrical padlo~k body 10. At the right end in Figures 4 and 5, the cover ha inwardly extending, short, flexible and resilient projections 121 which angage the front end face 11 of the padlock body. These ~2'~94~
projections are substantially spaced radially outward from the knob 12 of the padlock. At its left end in Figures 4 and 5 the cover has a radially inwardly extending annular lip 116 with a circular inner edge 117. In the embodiment shown, this lip holds a photograph P flat against the back end face 13 of the padlock body. The cover has longitudinal slots 118 and 119 which are open at the end of the cover where the projections 121 are located. These slots slidably receive the legs of the shackle S on the padlock.
The cover of Figures 4 and 5 is applied to the padlock body by sliding it from back to front over the padlock body.
The deformable projections 121 slids across the cylindrical body of the padlock and then they snap inward when they reach the front end 11 of the padlock body.
Figure 6 shows a third embodiment of the present cover having a cylindrical side wall 214 for snugly encircling the cylindrical body 10 of the padlock along its entire length.
At the front end the cover has an integral annular lip or bead 216 of circular cross-section, the inside of which projects slightly radially inward across the front end face 11 of the padlock body. At its back end the cover has flexible and resilient projsctions 221 like the projections 21 in the embodiment of Figures 1-3. Longitudinal slots 218 and 219 in the top o* the cover are open at it~ back end.
Figure 7 shows a cover having a cylindrical side wall 314 with longitudinal slots 318 and 319 which are open at its back end and inwardly extending, flexible and resilient pro~ections 321 on its back end like the projections 21 in the first embodiment.
Figure 8 ~hows a cover having a cylindrical side wall 414, slots 418 and 419, and flexible "Velcro" strips 30 and 31 on its back end with locking filaments which engage each other when strip 30 overlaps strip 31. Strip 31 may be placed against the back end face of the padlock body and then strip 30 ~ay be pulled taut and appli~d against strip 31 to lock the two strips to each other across the end of the padlock body.

Pigure g shows a cover of two-piece construction having a s~mi-cylindrical upper piece 40 with longitudinal slots 18' and 19' open at its back end and a semi-cylindrical lower piece 41. The two pieces of the cover fit together at longitudinal tongue-and-groove joints 42 and 43 on opposite sides of the cylindrical body of the padlock. The two cover pieces 40 and 41 may be applied to the padlock body from above and below, respectively, to form a unitary annular cover for the padlock.
~igures 10-15 illustrate an alternative embodiment of the present invention.
Referring first to Figures 10 and 11, a padlock of known design is shown as having a cylindrical body 110 with a front end face 411 where a rotatable knob 412 is located and a back end face 413 (Figure 11). The knob 412 operates a combination lock mechanism inside the body of the padlock in the usual manner. At the top the padlock has the usual rigid reciprocable and rotatable shackle S of inverted U-shape which is down (as shown) when the lock is closed and is displaceable upward with respect to the padlock body when the lock is open.
When the lock is op n, *he padlock body may be rotated about one vertical leg 414 of the shackle, or vice versa, from the locking position of Fi~ure 12 to the released position o~ Figure 1~ .
The present cover is a substantially rigid, one-piece molded body of suitable plastic material having a heart-shaped outer side wall 415, and a slightly rounded~convex, front wall 416 extending laterally inward from the outer side wall 415 to a central opening 417. At the top of opening 417, the front wall 416 of the cover presents a downwardly projecting csntral lip 416 which extends directly in ~ront of the front end face 411 of the padlock body. Throughout its extent, the edge of the opening 417 is a substantial distance radially outward ~rom the knob 412 of the padlock so that it does not impede the user's fingers when he or she grasps the knob and turns it.
~' At the top on one side, the outer side wall 415 of the cover presents a circular opening 418 (Figure 15) which rotatably and slidably receives the leg 414 ~f tha padlock shacklet S, as shown in Figures 12 and 14. At the top on the opposite side, the outer side wall 115 of the cover presents a slot 419 which is open at the back of the cover and has a rounded, closed front end. This slot slidably receives the opposite vertical leg 420 of the padlock shackle S. Slot 419 has a chamfered edge 421 on its inner side at the back of the 10cover to facilitate the movement of shackle leg 420 into or out of this slot when the shackle is rotated on its opposite leg 414.
The present cover has a cylindrical inner wall 422 spaced laterally inward from its outer wall 415 and joined to the outer wall by lateral ribs 423 extending between them, as 15shown in Figures 11 and 15. The cylindrical inside surface of inner wall 422 is substantially complementary to the cylindrical side wall of ths padlock body 410 so that the padlock body is slidably but snugly received inside the inner side wall 422 of the cover, as shown in Figure 11. At the lip 416 (Figure 10) 20and on opposite sides of it along the top of the front opening 417, the front wall 416 of the cover extends laterally inward past the inner wall 422 to engage the front of the padlock body.
At the top on one side, the inner side wall 422 has an opening 418a (Figure 15) which is spaced below and vertically 25aligned with, the opening 418 in the outer side wall 415. At the top on the opposite side, the inner side wall 422 has a slot ll9a (Figures 13 and 15) which is spaced below, and vartically aligned with, the slot 419 in the outer side wall 415 and is the same size and shape as the latter, looking down 30on the cover from abova it. The inner side wall opening 4~8a slidably and rotatably receives the padlock shackle leg 414 and the slot 419a slidably passes the opposite leg 420 of the shackle.
With the shackle S in an open postion, the padlock 35410 may be placed inside the present cover by positioning the padlock body behing the cover and sliding the free end of shackls ~t leg 420 through opening 418a in the inner side wall 422 of the cover and then out through the aligned opening 418 in the outer side wall 415 of the cover, and then pushing the rest of the shackle through these openings until the opposite shackle leg 414 is in these openings and the padlock body is seated inside the inner side wall 422 of the cover, with the rotatable knob 412 of the padlock in front of the cover, as shown in Figure 13. The shackle may be rotated from its released or unlocked position ~Figure 14) to the locking position (Figure 12) in which its leg 410 may be pushed into the padlock body for locking engagement with the locking mechanism therein.
When the padlock is closed, the present cover cannot be removed from it because of the engagement of the shackle leg 414 in the openings 418 and 418a in the cover. This effectively prevents any removal of the cover by a person who does not know the combination to open the lock. When the lock is open, the present cover may be mounted on it or removed from it without great difficulty. Ordinarily, however, the owner will keep the cover on as long as the lock is in use since it provides physical protactisn for the lock, as well as identifying it to tha owner and improving its appearance.
