Martin, East Longmeadow, Mass, assignor to Phelon Magnagrip Company, Inc East Longmeadow, Mass, a corporation of Massachusetts Filed Nov. 26, 1962, er. No. 240,473 8 Claims. (Cl. 317-159) This application is a continuation-in-part of my copending application Serial No. 71,064, filed November 22, 1960, now abandoned and bearing the title Magnetic Holder.

' This invention relates to a magnetic holder or rack of the general type which utilizes one or more permanent magnets and which is adapted to hold articles consisting at least partially of magnetic material. More particularly, the invention relates to a magnetic holder of the general type mentioned and which is particularly adapted for holding kitchen utensils such as cutlery, shears and the like; and which may also be used to advantage -in a workshop for holding small metallic tools and other articles.

It is the general object of the present invention to provide a magnetic holder of the type mentioned which utilizes a ceramic magnet and which is of a desirably simple and yet durable construction particularly well suited to low cost quantity production.

The drawings show two embodiments of the invention and such embodiments will be described, but it will be understood that various changes may be made from the constructions disclosed, and that the drawing and description are not to be construed as defining or limiting the scope of the invention, the claims forming a part of this specification being relied upon for that purpose.

FIG. 2 is a rear view of the holder of FIG. 1 with a portion of a pole bar therein broken away.

FIG. 3 is a longitudinal section taken generally as indicated by the line 3-3 in FIG.-1.

FIG. 4 is a vertical transverse section taken as indicated at 4-4 in FIG. 3.

FIG. 5 is a fragmentary front View of a pole bar forming a part of the holder.

8 FIG. 6 is a fragmentary bottom view of the pole bar of FIG. 5.

FIG. 7 is a front view of a second holder embodying the invention.

FIG. 8 is a rear view of the holder of FIG. 7.

FIG. 9 is a fragmentary section taken as indicated at 9-9 in FIG. 8.

FIG. 10 is a fragmentary front view of a pole bar forming a part of the holder of FIG. 7.

The magnetic racks or holders of the present invention are adapted to be mounted on a wall of a room or the like as indicated generally in FIGS. 1 and 7. The manner in which articles may be held by the racks or holders is illustrated in FIG. 1 wherein two articles of cutlery 1t) and 12 and a screw driver 14 are shown on the holder. The FIG. 1 holder has an elongated non-magnetic housing indicated generally at 16 which is adapted to be at tached to a room wall or the like which has a substantially flat elongated front wall 18. The front wall 18 is held in spaced relationship with a room wall or the like when the housing 16 is mounted thereon and, as shown, the housing 16 also has elongated top and

bottom walls

20 and 22 integral with the front wall 18 and short integrally formed

opposing end walls

24 and 26. Partially

circular end flanges

28, 28 formed at rear edge portions of the'end

walls

24, 24 are provided with circular 3,195,021 Patented July 13, 1965 openings 30, 39 for convenient attachment of the housing to a room wall or the like by means of screws or other suitable connecting devices.

In accordance with the invention, the hat elongated front wall 18 of the housing 16 is provided with vertically spaced longitudinally extending openings. Preferably,

and as shown, said front wall is provided with an upper longitudinally extending series of longitudinally spaced and longitudinally aligned horizontal openings or

slots

32, 32. Eight

slots

32, 32 are shown, but the number of slots may vary widely. A lower longitudinal series of longitudinally spaced and longitudinally aligned horizontal openings or

slots

34, 34 is preferably also provided and said slots are equal in number to the

slots

32, 32 in the upper series of slots and are in vertical alignment or registry therewith in the FIG. 1 holder.

Further in accord with the invention, an elongated generally U-shaped pole bar of magnetic material is provided and such a bar is indicated generally by the reference numeral 36. Said bar is disposed behind the front wall of the housing with its body portion in spaced relationship with saidwall and with longitudinally extending free edge portions thereof projecting forwardly through openings or slots in said front wall so as to be engaged by and to hold magnetic articles. As shown, the pole bar 36 has a substantially flat generally rectangular body portion 38. Upper and lower elongated side portions or

arms

40 and 42 of the pole bar 36 are each provided with a longitudinally extending series of forwardly

open notches

44, 44. The

notches

44, 44 are equally spaced longitudinally and they serve to define

teeth

46, 46 on the upper arm 40 and

teeth

48, 48 on the

lower arm

42, 42. The

teeth

46, 46 are in vertical alignment or registry with the

corresponding teeth

48, 48. Eight

teeth

46, 46 and eight

teeth

48, 48 are provided when the front wall 18 of the housing 16 is provided with eight

slots

32, 32 and eight

slots

34, 34 as shown.

When the pole bar 36 is disposed behind the front wall 18 of the housing 16, the eight

teeth

46, 46 project forwardly through the eight

slots

32, 32 in said front wall and the eight

teeth

48, 48 project forwardly through the eight

slots

34, 34 in said wall. As will be seen, magnetic flux is concentrated at the

teeth

46, 46 and 48, 48 and articles of magnetic material may be placed thereagainst so as to be held thereby. Referring back to FIG. 1, it will be seen that the articles of cutlery 10 and 12 have their blades in fiat engagement with the longitinaliy extending free edge or end surfaces of vertically aligned pairs of

teeth

46, 48 and 46, 48. The screw driver 14, on the other hand, engages adjacent end portions of the end surfaces of two

adjacent teeth

46, 46 and similar end portions of the end surfaces of two

adjacent teeth

48, 48 aligned vertically with the said two

teeth

46, 46.

The manner in which the pole bar 36 is secured in position within the housing 16 may vary widely but, as shown in FIG. 1 and as presently preferred, said pole bar is detachably connected to a central spacer member or rib 50 and to left and right-

hand lugs

52 and 54. The rib 50 is formed integrally with the top and

bottom housing walls

20 and 22 and the front housing wall 18 and extends between said top and bottom walls at a central portion of the housing. The rib also extends rearwardly from the front wall 18 to a plane spaced forwardly from the rear edges of said top and bottom walls. That is, the rear end surface of the rib 50 or, more specifically, the rear end surface 56 of an enlargement 58 thereon lies in a plane spaced forwardly from the rear edges of. the top and

bottom walls

20 and 22. A threaded opening 60 in the enlargement 58 is adapted to receive a screw 62 entered in a suitable opening formed at a central portion of the pole bar 36.

The left and right-

hand lugs

52 and 54 are formed respectively at the junctions of the front wall 18 and the

end walls

24 and 26. Said lugs have similar coplanar rearwardly facing fiat surfaces 64 and as which lie substantially in the plane of the rear end surface 56 of the enlargement S8. Opposite end portions of the pole bar 36 or, more specifically, end tabs 63 and '70 on said bar flatly engage said

surfaces

64 and 66 when the pole bar is held in position within the housing as shown.

Screws

72 and 74 entered in suitable openings in the tabs 63 and 7d and in suitably threaded openings in the left and right-

hand lugs

52 and 54 may also be provided to secure the pole bar in position.

It will be observed that the upper and lower end portions of the rib d are entered in a centrally located pair of

notches

44, 44 in the

arms

40 and 42 of the pole bar 36. Similar generally

rectangular cavities

76 and 78 are defined on left and right-hand sides of the rib 50 and these cavities respectively receive first and second or left and right-hand generally rectangular permanent magnets 80 and S2. The magnets Sit and 82 are of the ceramic type and they each have opposite parallel flat pole faces at the front and rear. Thus, the magnets may be placed in desired locations on the fiat body portion 38 of the pole bar 36 .and they will thereafter adhere to the pole bar and remain in such locations. The magnets provide a field which is concentrated at the aforementioned projecting end surfaces of the teeth 4-6, 4-6 and 43, 48 to hold magnetic articles in engagement with said end surfaces.

Preferably a series of

small lugs

84, 84 are provided internally along the junction line between the top wall 20 and the front wall 18 and a similar series of

small lugs

86, 86 is preferably provided internally along the junction line between the bottom wall 22 and the front wall 18. The

lugs

84, 84 and 86, 86 substantially strengthen the top and bottom walls 2%) and 22 of the housing 16 and they also serve an additional purpose. As shown, the said lugs project inwardly in the

notches

44, 44 between the

teeth

46, 46 and in the notches 44 between the teeth 48, 43. The inner end surfaces of the

lugs

84, 84 and 86, 86 are spaced inwardly from the

teeth

46, 46 and the

teeth

48, 48 and said surfaces serve to maintain the

magnets

80 and 82 in vertically spaced relationship with the

arms

40 and 42 of the pole bar 36.

In FIGS. 7 through there is shown a second holder which is identical with the holder of FIGS. 1 through 6 except for the provision of vertically staggered teeth 46a, 43a, and notches 32a, 34a, and the provision of a central spacer member 50a replacing the central rib 58. The staggered teeth 46a, 43a serve the same purpose as the aforedescribed teeth 46, 43 and require no further description here. The central member 50a serves to engage the pole bar 36:; as best shown in FIG. 9 and maintains the magnets Eida, 82a in longitudinally spaced relationship.

vFrom the foregoing, it will be apparent that the magnetic holders shown and described are of desirably simple and durable construction well suited to low cost quantity production. The

housings

16, 16a may be advantageously formed of plastic or a nonmagnetic metal such as aluminum in mass production molding or casting operations. The pole bars 36, 3611 may be advantageously formed from long strips of U-shaped cross section with only a minimum number of cutting operations necessary. Finally, the ceramic magnets 89, 8dr: and 82, 82:; are of identical construction and they are obviously of a conventional configuration well suited to low cost quantity production.
