Description
Sept. 13, 1955 c. w. CHENEY SLIDABLE BOLT FASTENING Filed Sept. 24, 1952 /NVINTO Charm W Hmm Chgne By @Aww A Mmm 9&- AHORA/En United States Patent Otiice 2,717,795 Fatal-ated Sept. 13, 1955 SLIDABLE BGLT FASTENDJ G Charles William Cheney, Hockiey, England Application September 24, 1952, Serial No. 3l,231 Claims priority, application Great Britain May 3, 1952 1 Claim. (Cl. 292-175) Slidable-bolt and rigid hasp fastenings are well known and extensively used on flexible portfolios and like bags. The slidable bolt member is in the form of a catch rigidly to the flap of the bag has upon its back a rigid elongated loop adapted to engage a slot of the boltmember and to snap engage with the nose of the said bolt of the bolt-member when the ap closes the entrance to the said body.
The invention relates to this kind of fastening and provides a combination of parts hereinafter fully described with reference to the accompanying drawing and specifically claimed; the essential features of the combination are a rigid hasp, an elongated loop rigid on the back of the hasp, and a ilat plate spring secured within the casing of the bolt-member and having two spring arms adapted to operate oppositely one against each end of the loop when the latter is hand forced into engagement with the nose of the bolt to thereby put said arms into power sufficient to freely and fully eject the loop when the bolt is hand retracted.
In the drawings,
Fig. 1 is a section of the fastening and hasp in engaged positions.
Fig. 2 is a back view of Fig. l.
Fig. 3 is a transverse section of Fig. l on dotted line A B.
Fig. 4 is a front View of hasp, separately.
Fig. 5 is a front view of the bolt member, separately.
Fig. 6 is a plan of the plate spring, separately.
Fig. 7 is an edge view of Fig. 6.
The hasp member 1 is of usual rigid construction, having the usual elongated rigid loop 2.
The bolt member 3 comprises, as usual, casing 4, spring-shot bolt 5 slidable within the casing, hand knob 6 on face of casing and connected to the bolt 5, and (optional) locking plate 7 pivoted on casing if key locking is desired.
The casing 4 is provided by the front plate 4a and back plate 4c clinched together at 4d and 4e, the front plate being provided with the usual elongated slot 4f to receive the elongated loop 2 of the hasp member 1, in the manner clearly shown by Figs. 1, 2 and 3.
The bolt has the usual nose 5a crossing normally the slot 4f the spring for shooting the bolt 5 being shown at 8 pressing against the bolt at 8a and against the casing at 8b, through the locking plate 7 for convenience only, as the bolt member 3 may not be provided for key locking.
A plate spring 9 having two opposite spring arms 9a, 9b is xed snugly Within the casing 4 to lie flat substantially against the front and back plates 4a and 4c with the free ends of its spring arms extending normally one over each end of the slot 4f for the purpose of engaging forcibly and resiliently each end of the loop 2 of the hasp when said loop is snap engaged with the bolts at each end.
The spring device 9 comprises two side bars joined by semi-circular ends so that there is no binding of the loop in the slot 9c, the one side bar providing the spring arms 9a, 9b `anti the other side bar a carrier for said arms and means for clinching the device 9 to both plates 4a and 4c of the casing 4, said device 9 being positioned longitudinally between side walls 10 of the casing 4. The semi-circular ends 9c are given resiliency by the piercing 9d whereby the arms derive resiliency from a twisting stress of the semi-circular end 9c.
When the loop such as 2 is forced into engagement with the bolt nose 5a the spring arms ride up the inclined ends of the loop with strong resilient resistance until held by the bolt nose. When the bolt 5 is retracted from the hand knob 6 the loop is ejected by the arms exerting resilient pressure on the loop at both ends.
Proposals have been made to cause the hasp to be ejected from the bolt member by a spring when the bolt thereof has been retracted and for this purpose a coiled spring has been located in `a well arranged between a front plate and a back plate of the bolt member, the base of the spring lying on the back plate and the head of the spring having a superposed follower engaging the nose of a pin on a hasp. This construction has the disadvantage that it is not only expensive to produce and assemble, but the well occupies considerable space in the bolt member in the depth thereof and consequently the thickness of the casing is increased.
I claim:
A slidable bolt fastening comprising a slidable bolt member and a hasp member adapted for co-operation, said bolt member comprising a casing constructed of a front plate and a back plate rigidly assembled together and having coincident elongated slots therein, a springsaid slots and adapted to act upon the back of said loop and to eject it when said bolt is retracted by said knob, said spring consisting of a plate made of springy material and iiXed between the said front and back plates and incorporating a carrier secured at its ends between said plates and two spring arms each raised out of the plane of said carrier and arranged relatively to the said slot in the front plate as so to be engageable by the back of the said loop, the arrangement being such that the said spring arms impose a two-positional bias on the back of said loop for transmitting lateral ejecting forces on the hasp when the latter is released from the bolt.
