Definitions
- the present invention relates to a catch or lock.
- a lock having a rotatable cam, means in or on the cam for accepting a key, a latch comprising at least one latch arm with a latching means which arm co-operates with the cam, a hasp with which the or each latching means is or are engageable, the arrangement being such that the cam may be rotated to permit disengagement of the latching means from the hasp, at least one abutment which forms a stop for the cam to determine the position thereof in its releasing and locking positions, the key being insertable or removable when the cam is in the locking position.
- This known lock does not have a supplementary releasing position in which the key is insertable or removable which allows the lock to be set in a semi-permanently disengaged condition.
- the present invention is characterised in that two abutments forming stops to determine the position of the cam in releasing and locking positions are provided at each end of a second portion of a groove, a first portion of said groove is provided with a ramped bottom, the cam having a follower engaging in the groove, the ramped bottom being such that the cam can be moved from the first portion to the second portion but not in reverse, the key being insertable or removable at a first supplementary releasing position of the cam when the follower is in the first groove portion.
- 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 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.
- 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.
- 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.
- FIG. 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 a screw 8, the screw 8 and stud 5 firmly locating the latch member's rear portion 9 on the casing.
- the casing also has a key aperture 12 surrounded by a bearing protrusion 13 for engaging with a recess 14 in the cam 3.
- the casing has a groove 15 which has a ramped first portion 16 and a second portion 17. The groove receives a follower 18 projecting from the bottom of the cam and the follower can rotate anti-clockwise over the ramp in the groove from a first abutment 50 at a position X in Fig. 1 and into the second portion 17 extending from a second abutment 51 to a third abutment 52 but cannot rotate clockwise from second portion 17 to a first portion 16 because of the ramp the end of which forms the second abutment 51.
- 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 a circular flange 22 of the cam so as to hold the cam onto the casing, and latch portions 24 terminating in hooks 25 which engage with barbs 26 of the hasp.
- the cam 3 is formed with a central triangular portion 30 in which is a recess 32 for a key 33 having a double bit 34.
- the portion 30 also has a hole 35 to receive the stem end 36 of the key.
- the cam also has a follower 18, a retaining flange 22 and recess 14 as already described.
- the hasp is formed as described with two barbs 26 extending either side of a stem 28 (Fig. 6).
- a bridge 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 the follower 18 in position X. If it is required to use the lock the plug is removed, the key inserted in cam 3 into aperture 32 and the cam rotated so that the follower snaps over the ramp into second 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 because recess 32 is misaligned with aperture 12. When the cam is in position Z as shown in Fig. 5 the hasp 4 can be sprung in locking engagement with latch member 2.
- 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 120° 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 the groove 15 is about 120° and the second portion 17 about 60° with an allowance for cam follower thickness.
- 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.
- the groove can be circular with the second portion 120° and the first portion 240° in arcuate length.
