Ross [5 7] ABSTRACT A handle to be attached to a lid has a pair of lugs passing through respective slots in the lid, each lug having a bore which lies on the opposite side of the lid upon such insertion and which is formed with a sill rising toward the handle. A pair of generally boot-shaped clips, made like the handle of a resiliently deformable plastic material such as polypropylene, have pointed stems which fit into the bores of the lugs and are provided with reduced portions forming recesses into which the sills may snap when the stems are fully pushed into the bores, thereby interlockingly engaging the lugs and preventing their withdrawal.
7 Claims, 4 Drawing Figures HANDLE CLAMP My present invention relates to an assembly for permanently fastening an attachment, such as a handle, to a lid, panel, partition or other generally fiat structure of limited thickness hereinafter referred to as a wall member.
The general object of this invention is to provide simple means for quickly fastening such an attachment to a wall member, accessible from both sides, in a manner preventing subsequent spontaneous or nondestructive voluntary detachment.
-A more particular object is to provide a fastener of this character adapted to be installed with a simple movement of the fingers, thus at a location of limited accessibility such as on the inside of a container wall provided with an opening just large enough to permit the insertion of one s hand.
I have found, in accordance with this invention, that the foregoing objects can be realized with the aid of a latch element of resiliently deformable material having a stem with a pointed end receivable in a bore of a lug, integral with the handle or other attachment to be secured, which passes through a slot in the wall member so that the aforesaid bore lies on the side remote from the attachment; an inner peripheral surface of the bore is formed with a sill which rises therefrom toward the attachment and is lockingly engageable by a reduced portion of the latch stem adjacent a blunt end thereof. Thus, pressure exerted upon the blunt end, eg with the tip of one finger, suffices to lock the attachment in position by irreversibly letting the locking element snap into engagement with the lug. In the case of a handle or other attachment to be fastened to the wall member at two points, two such latch elements will be used to engage a pair of lugs passing through respective slots.
Advantageously, pursuant to a more specific feature of my invention, each latch element is in the form of a generally boot-shaped clip with an instep in the region of the sill-engaging recess, this instep being flanked by a sole and a'heel bearing upon the wall member on opposite sides of the slot. The boot shank, representing the blunt end of the clip, may come to rest against a resilient outer rib of the coacting lug which urges the heel in line with that shank into firm contact with the wall member.
The invention will be described in detail hereinafter with reference to the accompanying drawing in which:
FIG. 1 is a top plan view of an assembly embodying the invention, including a container lid with a handle attached thereto;
FIG. 2 is a cross-sectional view taken on the line II ll of FIG. 1;
FIG. 3 is a cross-sectional view taken on the line Ill III of FIG. 2; and
FIG. 4 is a side-elevational view of a latch element forming part of the assembly of FIGS. 1 3.
In FIGS. 1 3 I have shown a container lid formed with a pair of aligned slots 11, 11 and with a large opening 12, normally serving for the filling or emptying of the container, giving access to the underside of the lid; the hole 12 may be closed by a plug not illustrated. Lid 10 may consist of plastic sheet material, as shown, but could also be metallic.
A handle 13, of resiliently deformable plastic material such as polypropylene, has two bases 14, 14 resting flat against the top surface of lid 10 in the region of slots 11 and 11, these bases being integral with a pair of lugs 15, 15' which pass through the slots and are provided with bores 16, 16 emerging from the underside of the lid upon insertion of the lugs into the slots. Since the two lugs are identical, only lug 15 will be described in greater detail below.
As best seen in FIG. 3, the bore 16 of lug 15 is formed along its inner wall surface with an upstanding sill 17 lying substantially in a central plane of the lug. A generally boot-shaped clip 18 of the same or similar thermoplastic material, shown by itself in FIG. 4, has a pointed tip 19 for easy insertion into the bore 16 by a user reaching through the hole 12 to fasten the handle 13 in position. The shank portion 20 of the boot terminates in a reduced heel 21 which is separated from its sole 22 by an instep 23 bounded (in the upright view of the boot, FIG. 4) by a gently curved lower edgeand by a sharply stepped upper edge forming a recess 24. Upon insertion of the stem of clip 18 into the bore 16 of lug 15 by a movement from right to left as viewed in FIG. 3, the instep portion 23 is resiliently deformed until the sill 16 engages in the undercut 24 whereupon the instep 23 snaps back into its normal position, with the heel 21 and the sole 22 now bearing upon the underside of lid 10 at opposite sides of slot 11. Owing to the fact that the heel projects beyond a plane P which is perpendicular to the shank 20 and tangent to the sole 22, the shank 20 is deflected toward the lug 15 into a slightly tilted position in which it rests against and deforms an outer rib 25 of the lug whose resiliency presses the heel 21 firmly onto the lid 10; rib 25 is formed by a step in the median plane registering with sill 17.
The joint thus formed between the lid 10 and the I handle 13 at its base 14 cannot be broken by finger pressure alone though the parts, of course, could be separated by the use of tools which generally would destroy the clip 18 and/or the lug 15.
Upon insertion of a second, identical clip into lug 15', handle 13 is firmly anchored to the wall member 10.
It will be noted that, with the sill 17 snapped into the recess 24 of the clip 18, an enlarged part of that clip immediately to the left of that recess (FIG. 3) is in firm contact with the wall of bore 16 next to the sill, this wall forming a land 16a wider than the recess 24; the flat shape of this enlarged part, together with that of sole 22, helps prevent any rotation of the clip relative to th bore.
I claim:
1. In a structure including a wall member accessible from two sides and provided with at least one throughgoing hole, the combination therewith of:
an attachment for said wall member provided with a base larger than said hole carrying a lug insertable into said hole, said lug upon such insertion having a part projecting from said hole on the side remote from said base, said part being formed with a transverse bore having an inner peripheral surface with a sill rising therefrom toward said attachment; and
a latch element of resiliently deformable material having a stem with a pointed end receivable in said 7 latch element consists of elastomeric material.
3. The combination defined in claim 2 wherein said elastomeric material is polypropylene.
4. The combination defined in claim 1 wherein said attachment is a handle with two extremities provided each with a base carrying a lug insertable into a respective hole of said wall member, said latch element being duplicated for engagement with both said lugs.
5. The combination defined in claim 1 wherein said latch element is generally boot-shaped, said reduced portion being located at the instep of the boot.
6. The combination defined in claim 5 wherein said latch element is formed with a sole and a heel bearing upon said wall member on opposite sides of said hole said heel being an extension of the boot shank projecting beyond a plane perpendicular to said shank and tangent to said sole.
7. The combination defined in claim 6 wherein said lug consists of elastomeric material and is provided with a resilient outer rib bearing upon the top of said boot shank for urging said heel into firm contact with said wall member.
