Abstract
Description
- The present invention relates to a catch or lock.
- A catch or lock in accordance with the invention comprises a rotatable cam, means in or on the cam for accepting a key so that the cam can be rotated, at least one latch arm and a hasp, the latch or latches being biassed into engagement with the cam, the latch or latches being engageable with the hasp for locking, the arrangement being such that on insertion of the key into the catch or lock the cam may be rotated to disengage the latch or latches from the hasp, wherein a casing is provided, and wherein a groove is provided on the casing or cam with a ramped bottom so as to divide the groove into two portions, the cam or casing having a follower engaging in the groove, the ramp being such that the cam can be moved by the key from the first portion to the second portion but not in reverse, the key being able to be inserted or removed when the latch or latches are disengaged at a first position of the cam when the follower is in the first groove portion and the key being able to be received or inserted when the latch or latches are engaged at a second position of the cam when the follower is in the second groove portion, the cam being movable to a third cam position when the follower is in the second groove portion at which third position the latch or latches are disengaged.
- The arrangement provides a very simple lock which is economical to mould and can be operated by a simple key which is preferably double bitted.
- The advantage of the above arrangement is that the catch or lock can be in a semi-permanently disengaged condition when the cam follower is in the first portion and is inoperative. This is particularly useful for a dispenser for paper towels and the like which some operators prefer to be unlocked. In this case the cover is retained by suitable non-locking means such as a stud springing into a hole.. If the dispenser operator requires the cover to be lockable, the cam follower is turned by the key to the second groove portion where the lock or catch is fully operative.
- Preferably the cam is substantially triangular in shape and two latches are provided, the cam acting between the latches so that on rotation of the cam both latches are disengaged from the hasp.
- The invention will now be described by way of example with reference to the accompanying drawings in which:
- Figure 1 is a plan view of a catch or lock according to the invention with the cam in a groove first portion and unlatched,
- Figure 2 is a cross section of part of Fig. 1 taken on AA with a key for operating the lock,
- Figure 3 is a plan view of the catch or lock of Fig. 1 showing the casing only,
- Figure 4 is a cross-section of the casing of Fig. 3 taken on BB showing particularly the groove,
- Figure 5 is a plan view of the catch or lock of Fig. 1 with the cam in a groove second portion and latched, and,
- Figure 6 is a plan view of the catch or lock of Fig. 1 with the cam in the groove second portion and unlatched .
- In Figure 1 of the drawings a catch or lock is shown formed from four main parts, namely a casing 1, a double latch member 2, a cam 3 and a
hasp 4. - The casing as shown in Figures 3 and 4 comprises a stud 5 engageable with a hole in the latch member 2, and a protrusion 6 with a tapped
hole 7 to receive ascrew 8, thescrew 8 and stud 5 firmly locating the latch member's rear portion 9 on the casing. The casing also has akey aperture 12 surrounded by a bearing protrusion 13 for engaging with arecess 14 in the cam 3. Also the casing has agroove 15 which has a rampedfirst portion 16 and asecond portion 17. The groove receives afollower 18 projecting from the bottom of the cam and the follower can rotate anti-clockwise over the ramp in the groove from position X in Fig. 1 and into thesecond portion 17 but cannot rotate clockwise fromsecond portion 17 tofirst portion 16 because of the ramp. - The double latch member 2 as shown in Figure 5 comprises a rear portion 9 firmly located to the casing as described above,
resilient portions 20 extending from the fixed rear portion 9,cam engaging portions 21 which overlie acircular flange 22 of the cam so as to hold the cam onto the casing, andlatch portions 24 terminating inhooks 25 which engage withbarbs 26 of the hasp. - The cam 3 is formed with a central
triangular portion 30 in which is arecess 32 for a key 33 having adouble bit 34. Theportion 30 also has ahole 35 to receive thestem end 36 of the key. The cam also hasfollower 18, aretaining flange 22 and recess 14 as already described. - The hasp is formed as described with two
barbs 26 extending either side of a stem 38 (see Fig. 6). - In order to ensure that when the key is inserted in the cam that the
latch portions 24 are not forced out of engagement with the hasp abridge 40 secured to the casing may be provided (see Figs. 4 and 5). - A plug (not shown) can be fitted in
casing key aperture 12 if the lock is not to be operative. - The lock is normally supplied with the plug in
aperture 12 and the lock is in a non-locking state as shown in Fig. 1 with thefollower 18 in position X. If it is required to use the lock the plug is removed, the key inserted in cam 3 intoaperture 32 and the cam rotated so that the follower snaps over the ramp intosecond groove portion 17 on reaching position Z as shown in Fig. 5 the key can be removed and the lock is latched. To unlatch the lock the key is reinserted and the cam moved to position Y as shown in Fig. 6. In this position the key cannot be removed becauserecess 32 is misaligned withaperture 12. When the cam is in position Z as shown in Fig. 5 thehasp 4 can be sprung in locking engagement with latch member 2. - It will be obvious from the fact that the cam 3 has an equilateral triangular shape that starting at position X (as in Fig. 1) where the key is insertable and the latch member is open, the cam is movable after key insertion through 1200 to position Y (as in Fig. 6) where the latch member is again open. Thence the cam moves through a further 60° to position Z (as in Fig. 5) where the key is removable and the latch member is closed. The total cam movement being 180° (the arcuate length of the groove being slightly greater to allow for cam follower thickness and the
first portion 16 of thegroove 15 is about 120° and thesecond portion 17 about 60° with an allowance for cam follower thickness. - A particular use for the lock described above as in a dispenser for paper towels and such like where some operators prefer the dispenser to be permanently unlocked whilst some operators prefer a lockable dispenser.
- It will be appreciated that the casing 1 can form part of an article to be locked that is being integral with the object being locked or else the casing can be a plate or the like which is attached by attachment means such as screws to the object being locked.
- It will also be appreciated that whilst the follower is described as being on the cam and the groove in the casing, the reverse is within the scope of the invention and would be equally effective. Also the groove can be circular with the second portion 120° and the first portion 2400 in arcuate length.
