TOGGLE BOLT Filed May 11, 1948 LLEWfLLYN. M 5551.
Fig- By a M I fluorney Patented Nov. 28, 1950 TOGGLE BOLT Llewellyn M. Seely, Oheltenham Township, Montgomery County, Pa., assignor to Super-Grip Anchor Bolt 00., Inc., Philadelphia, Pa., a corporation of Pennsylvania Application May 11, 1948, Serial No. 26,462
3 Claims.
This invention relates to a toggle-belt construction that can be manufactured cheaply and economically, and more specifically to one in which the anchor member can cooperate interchangeably with either the head of an ordinary bolt or with the nut of such bolt, the bolt being adapted to be removably inserted within the anchor member. The bolt may be an ordinary stove bolt which may be sold in combination with the anchor member, or the anchor member may be sold separately, to be later combined with the bolt by the purchaser. The present togglebolt invention thus comprises the combination of the anchor member and the bolt as well as the anchor member which can be sold as a separate article.
The invention further relates to a toggle-link which has the maximum strength and efficiency with the minimum cross-section. It further re lates to certain details of construction which will be more fully hereinafter described and claimed. In the accompanying drawing, I have shown an illustrative embodiment of my invention in which the same reference numerals refer to similar parts in the several figures.
Figure 1 is a vertical section through the support and the work to be supported showing the toggle-bolt in side elevation being inserted through an aperture in the support and work,
Figure 2 is a view similar to Figure 1 showing the work secured by the toggle-bolt in locked position, t
Figure 2A is a rear elevational view of the toggle-bolt shown in Figure 1,
Figure 3 is a perspective View of the anchor member alone which cooperates Withthe bolt,
Figure 3A is a plan view of the anchor member shown in Figure 3,
Figure 4 is a sectional View taken on lines 4-4 on Figure 3,
Figure 5 is an end view of the anchor member shown in Figure 3, and
Figure 6 is a vertical sectional view of the a cooperating polylateral nut l'l. These bolts may be sold combined either with the anchor member I or the anchor member may be sold separately.
The anchor member is preferably made of *a single metal blank of suitable guage sheet metal preferably of steel which is cut and stamped to produce an anchor member generally U-shaped in cross-section as shown in Figures 3 and 5. The anchor member is shaped so as to be provided with a pair of spaced parallel side walls 2| and 22 positioned at substantially right angles with a connecting wall forming the bottom of the channel shaped anchor member. The ends 2 I and 22 of the side walls are preferably curved or tapered as shown in the drawings. The bottom wall is out along lines 2, 3 and 3' as shown in Figure 3A and bent inwardly of the channel portion at substantially right angles to the bottom wall 20 so as to provide a partition member 23. As a result of bending the partition member inwardly of the channel, a rectangular opening 28 is provided in the medial region of the bottom wall 20. An opening 26 is also provided in the bottom wall adjacent the opening 28 of suitable dimension to receive the bolt l5 therethrough. An opening 2! is also provided in the partition of suitable dimension to receive the bolt I5 therethrough. The openings 26 and 21 can be conveniently formed by punching out an opening in the flat blank so that when the partition member 23 is bent inwardly the two openings 26 and anchor member showing a bolt assembled there- Ordinarily, I use what is known as a stove bolt 7 having at one end a head it provided with a groove l6 for engagement with a screw-driver and threaded at the other end and provided with 2'! will be properly located in communicating relation to each other as shown in Figure 3 for a purpose to be explained later. The openings 26 and 21 are preferably semi-circular in shape at the ends thereof for receiving the bolt Hi.
The partition member 23 is positioned past the median point of the anchor bolt so that dimension Ais less than dimension B as indicated in Figure 2A. This construction permits the anchor member to tilt by gravity on the bolt assembled therewith as will be explained hereinafter.
A small slit :4 is also provided adjacent the opening 26 in the rear wall 20 and the wall is pressed outwardly adjacent the slit to provide a small protuberance or stop element 25 for engaging a lateral face of the nut I! as shown in Figures 2 and 2A.
The anchor member I is assembled for use with a bolt l5 by passing the end of the bolt through opening 26 and then positioning the nut H at the threaded end thereof. The bolt is then tilted so as to assume a horizontal position in alignment With the anchor member! as shown in wbeam :across the :opening of the hole.
3 Figure 1. When the bolt i5 is tilted into horizontal position it will pass from opening 26 to the communicating opening 2? in the partition member 23 and at the same time nut ll will enter into opening 28 to assume the position shown in Figure l.
The assembled anchor memberand bolt in the extended position described can be readily inserted through an opening or aperture in the support It and work I l desired to be attached thereto by the bolt. As soon as the anchor member passes through the aperture I0 to clear the "rear face of the support l0 it will tilt by gravity to assume the position shown in Figure 2. In this position the bolt l5 will rest on the partition '23 and a lateral face of the nut I! will engage the stop member 25 as shown in Figures 2 and 2A. The bolt is then turned by engaging a screwdriver with the head IS until the work H is securely fastened to the support It in the position shown in Figure 2. It will also be noted that the full length of the free edges 240i the side \walls 2,! and 22 will be brought into positive and frictional engagement with the rear face of the support 110. The anchor member thus securely holds the bolt in fixed position on the support.
If it is desired to have the threaded end of the bolt IE to extend outwardly of the work 14 0 the bolt 1 5 can be :readily inserted through the opening 26 in the anchor member -I in the position shown in Figure '6 and the nut I! can then be tightened against the'work toretainsame in the support. It is thus apparent that the anchor member can beassembled with a bolt in any desired relation depending :upon the use desired.
The present invention is adapted for togglebolts ofsall sizes to carryany load. For any given load the present toggle construction requires a minimum size holeto bedrilled through the support and work ,and yet provides great holding power because the-anchor member acts as-a-spring The par- .tition member .23 serves to support the bolt firmly on the :anchor member and at the same time positions the bolt :at right angles to the i work. The nut I? also-rests-fully with its-flatface when it is tightened by means of the nut H on U the "work.
It .will also be noted that in the present construction the opposed'wall portions 2! and 22 are .imperforate throughout, having no openings or :cuts ;of any kind, so thatthe full strength of the metal blank is utilized in this portion of the anchor member where it is most needed to function as a strut for resisting the force exerted by the bolt. The free continuous edges 24 of the side walls 2| and 22 also frictionally'engage for their full slength with the rear face 19' of the support and thus provide positive bearing means for the anchor member sothat the toggle bolt is firmly secured and'positi-vely retained position after it is fastened in final position on the'work.
Another advantage of the present toggle con-- .struction resides in being able to use with the anchor member any available bolt of proper size and diameter for insertion in the openings provided inthe anchor member previously described.
The anchor member. can ;be made from a single steel metal blank of suitable size and gauge by a single stamping operation at a minimum of cost and expense. The present invention thus provides a toggle-bolt construction that'is simple yet surprisingly efficient and effective and which can be conveniently used in a number of alternative relations to support a member on walls, ceilings and other structural members which cannot normally receive and retain a bolt in the member itself.
