,H KEY CASE 7 Sam Women Sam, Chicago, I11. I Application Februa 23, 1951, Serial No. 212,242

invention relatesto elastic key cases having a common key shaft and is an improvement on the key case disclosed in my copend'ing application for patent Serial Number 122,310 filed October 19, 1949.

An object is to provide a key case having a key shaft both of whose ends being integrally attached to opposite inner faces of the Wall's'of the key case.

Other objects and advantages become apparent as the description proceeds.

I attain these objects by a device illustrated in the accompanying drawing, in which-- Figure 1 is a side view of the preferred form of the key case;

Figure 2 is a front view of the preferred form of the key case;

Figure 3 is a side view of an alternative form of the key case, and

Figure 4 is a side view of a double form of the key case.

In Figures 1 and 2 is shown a key case comprising a pair of elastic, complementary, oppositely disposed

wall members

3 and 6 which are separate from each other and an elastic common key shaft 4 each of whose ends is integrally attached to the inner face of each of the wall members which normally substantially enclose keys 5 ringed on the key shaft 4. Wall member 6 is drawable through the eyelet of a key 5 to enable the key shaft 4 to be ringed by the key 5 and, to this end, has a projection 1 adapted to enter easily the eyelet of a key 5 and serving as a convenient handle to be grasped by the fingers to start drawing said drawable wall member 6 through the eyelet of a key 5. The projection I fits in a notch on the top edge of annular segment 8 normally ringing laterally and thus hold- 'SCIaims. (01. 150-40) ing securely the free end of keys 5 ringed on the key shaft 4. Annular segment 8 is a segment of wall member 3 which latter is adapted to release thefree ends of keys 5 ringed on the common key shaft 4 from its annular segment 8 for extension of the keys 5 outwardly from the key case by pulling its annular segment 8 in the direction away from the remainder of wall member 3. An elastic string member 2 is integrally attached to the lower end of the key case and an elastic loop I, adapted to ring a man's belt et cetera, is integrally attached to the string member 2. String members 2 and loops I are shown merely for the purpose of indicating an advantage of my elastic key case, namely, that the entire key case including loop I and string member 2 may be made of a single piece of soft rubber entirely in a single mold. Y

' The alternative form of key case illustrated in Figure 3 difiers from'the key case illustrated in Figures 1 and 2 only in respect to the elastic common key shaft 9 being tubular with both ends open instead of being solid'like key shaft 4 in Figures 1 and 2. The tubularform of key shaft facilitates the engaging of key shaft 9by a key.

In Figure 4 is shown a double form of key case comprising a common inner elastic wall member m -a pair of elastic complementary,symmetric, oppositely disposed wall members 6 and6 both identical to wall member 6 in Figures 1, 2 and 3 and separate from common inner wall member In, and a pair of elastic

common key shafts

4 and 4 identical to key shaft 4 in Figures 1 and 2. Each of the ends of one key shaft 4 is integrally attached to an inner face of common inner wall member ID and the inner face of a complementary wall member 6 and each of the ends of the second key shaft 4 is integrally attached to the second inner face of common inner wall member I0 and the inner face of the second complementary wall member 6. The common middle wall member l9 and both

complementary wall members

6 and 6 normally substantially enclose keys 5 engaging said pairs of '

key shafts

4 and 4. Each of the

complementary wall members

6 and 6 is drawable through the eyelet of a key to enable each corresponding key shaft4 to be engaged by the key. Common inner wall member l0 has a pair of annular

symmetric segments

8 and 8, identical to annular segment 8 in Figures 1 and 2, normally enclosing laterally and thus holding securely the free ends of keys engaging the pair of

key shafts

4 and 4. Common inner wall member I is adapted to release the free ends of keys engaging the pair of

key shafts

4 and 4 from the pair of

annular segments

8 and 8 for extension of the keys outwardly from the key case by pulling the pair of

annular segments

8 and 8 in the direction away from the remainder of the common inner wall member ID. The pair of

annular segments

8 and 8 are integrally disposed on opposite faces of common inner wall member 10 directly opposite each other. Each complementary wall member 6 has a projection 1 adapted to enter easily the eyelet of a key 5 and serving as a convenient handle to be grasped by the fingers to start drawing the drawable complementary wall member 6. Each projection I fits in a notch on the top edge of each annular segment 8.. The notches shown in Figures 1, 2, 3 and 4 help retain laterally projections I and together with them complementary wall members 6 in relation to wall members 3 and I0.

I claim:

1. A key case comprising a pair of elastic complementary oppositely disposed wall members each separate from the other and an elastic key shaft connecting and integrally attached to the inner face of each of said wall members, said wall members normally substantially enclosing keys engaging said key shaft, a said wall member being drawable through the eyelet of a key to enable said key shaft to be engaged by said key.

2. A key case as set forth in claim 1, said drawable wall member having a slender projection adapted to enter easily the eyelet of a key and to serve as a convenient handle to be grasped by the fingers to start drawing said drawable wall member through said eyelet of a key.

3. A key case as set forth in claim 1, a said wall member having an annular segment normale ly enclosing laterally and thus holding securely the free ends of keys engaging said key shaft, said wall member being ad pte to release the free ends of keys engaging said key shaft from said annular segment for extension of said keys outwardly from said key case.

4. A key case as set forth in claim 1, said key shaft being tubular to facilitate the engaging the key shaft by a key.

5, A double key case comprisin a common nner elastic wall member, a pair of elastic complementary Symmetr c wall members each separate from said common inner wall member and each disposed on opposite faces of said common inner wall member, and a pair of elastic common key shafts, one end of each of the key shafts being integrally attached to a face of the common wall member, the other end of each of the key shafts being integrally attached to the inner face of one of the complementary wall members, said common inner wall member and said pair of complementary wall members normally substantially enclosing keys engaging said pairs of key shafts, each of said complementary wall members being drawable through the eyelet of a key to enable each corresponding key shaft to be engaged by said key, said common inner wall member having a pair of annular symmetric segments normally enclosing laterally and thus holding securely the free ends of keys engaging said pair of key shafts, said wall member being adapted to release the free ends of keys engaging sa pair of key shafts from said pair of annular segments for extension of sa d keys outwardly from said key case by pulling said pair of annular segments in the direction away from the remainder of said common inner wall member, said pair of annular segments being integrally disposed on opposite fac s f said common inner wall member.
