LOCKING KEY FOR ADJOINING CABINET UNITS Filed May 9, 1952 [fix Em far Envy/4,20 W8/TL6B iffy s.
Patented Apr. 13, 1954 LOCKING KEY FOR ADJ DINING CABINET UNITS Richard W. Sltler, St. Charles, 111., assignor to Aurora Equipment Company, Aurora, 111., a corporation of Illinois Application May 9, 1952, Serial No. 286,933
2 Claims. (Cl. 312-111) This invention relates to attaching means for shelving or cabinet units to hold them together in alignment and more particularly to a simple key which may be inserted in aligned openings in end members of the units and which upon turning will lock the units together.
An object of this invention is to provide improved means for attaching or keying together cabinet units such as shelving and the like either in vertical or horizontal alignment.
In accordance with the general features of this invention there is provided attaching means for cabinet units such as shelving and the like including end members provided with pairs of spaced openings such as keyhole-shaped holes and capable of alignment or inter-registration, the attaching means being insertable into the registered openings to position fixedly and hold together said units by frictional camming engagement with the margins of said members defining said openings, each of said attaching means comprising a substantially fiat key inserted lengthwise through said aligned openings and turned therein with portions in said openings and with edges in engagement with opposite outer side surfaces of said members.
Other objects and features of this invention will more fully appear from the following detailed description taken in connection with the accompanying drawings which illustrate a preferred embodiment and in which:
Figure 1 is a fragmentary front view of a pair of cabinet or shelf units held together end to end by my novel key means;
Figure 2 is a cross sectional view taken on substantially the line IIII of Figure 1 looking downwardly;
Figure 3 is a fragmentary perspective view of end members of my units showing a key in the aligned openings and turned into interlocking position;
Figure 4 is a fragmentary view partly in section taken on the line IV-IV of Figure 2 showing the key inserted lengthwise in the aligned openings prior to turning in interlocking engagement; and
Figure 5 is a view similar to Figure 4 showing the position of the key after it has been turned into interlocking position.
As shown on the drawing:
The reference character I0 designates generally a unit which may be of the cabinet or shelf type and is of a well-known construction in the steel shelving or cabinet field. Any number of these units may be secured together end to end or stacked upon each other by my novel key means and as illustrative of the invention I have shown two such units in Figure l secured together.
Each unit Ill includes an angular end supporting member having flanges H and I2. The flanges H and II each has a given size opening i3 which may be of any desired shape such as a keyhole-shaped opening with converging side margins and which in the embodiment of this invention extends vertically although it could be located in any desired position or at any desired angle.
The opening in one flange II is so positioned as to be registerable with or aligned with the corresponding opening in the adjoining end member as shown in Figure 2. V
Cooperable with these aligned openings l3 for interlocking the end members of the units together are a plurality of key means each of which comprises a substantially fiat steel key [5. This key It has spaced pairs of slots It and I! in its edges and each pair defines a reduced section l8 between the slots.
In the use of the key it is inserted lengthwise as shown in Figure 4 through the openings l3 until its reduced sections l8-l8 are in the aligned openings l3. Then upon turning of the key its slots receive the edges of the marginal portions of the aligned openings so that the edges of the key are brought into engagement with opposite side surfaces of the flanges I l of the end supporting members of the units. When in this position, as shown in Figure 5, the units are tightly cammed together and are held. by the key i5 which can be easily removed when it is desired to separate the cabinets.
I claim as my invention:
1. In combination cabinet units each having supporting members provided with aligned pairs of spaced openings and capable of inter-registration and attaching means insertable into the registered openings in said members to position fixedly said units in spaced relation by frictional camming engagement with edges of the openings, each of said attaching means comprising a substantially fiat slotted edge key inserted 1engthsupporting members provided with aligned pairs of spaced key receiving openings capable of inter-registration and attaching means insertable into the registered openings in said members to position fixedly said units in spaced relation by frictional camming engagement with margins of said openings, each of said attaching means comprising a substantially flat key having spaced pairs of slots providing reduced sections between i the pairs of slots, said key being inserted length wise through said aligned openings and being turned with the edges of its slots cammingly engaging opposite side surfaces of said members with each reduced section being disposed in one of said aligned openings.
