Definitions

• the present invention relates to a locking device which is in ⁇ tended to permit the fixed locking of, for example a chain, at the same time as that locking member, suitably a screw, which is em- ployed for anchorage of the locking device proper, is rendered in ⁇ accessible in the locked state of the locking device.
• Fig. 1 is a perspective view of the locking device in the locked state
• Fig. 2 is a plan view of the locking device, with its locking hood dismounted
• Fig. 3 is a side elevation of the locking device with the locking hood dismounted
• Fig. 4 is an end elevation of the locking device of fig. 3, seen from the left;
• Fig. 5 is an end elevation of the locking device of Fig. 3, seen from the right;
• Fig. 6 is a plan view of the insert member which is fixedly anchored in the locking device proper; and Fig. 7 is an end elevation of a modified embodiment of a base portion of the locking device.
• the locking device has a base 2 portion 1 which as a substantially planar bottom face 2 and two side edges 3 and 4 bent upwardly approximately at right angles therefrom.
• the base portion will assume the configu ⁇ ration of a shallow U.
• a spacer 5 is fixedly disposed in the base portion 1, in the longitudinal direction thereof, the spacer extending throughout the entire length of the base portion.
• a guide member is mounted on the spacer 5 and has an outer end piece 6 and an inner end piece 7. Both of the end pieces are provided with lower edges 8 which are parallel to the bottom face 2 of the base portion 1, there being thereby created two elongate spaces 9, and 10 respectively, between the underface 8 of the guide member and upper face of the base por ⁇ tion 1, these spaces extending along the entire length of the base portion 1.
• a hood 11 is disposed about and over both of the end pieces 6 and 1 , as well as the rest of the locking device proper.
• the hood ' 11 has two side walls 12 and 13 which are interconnected, on the upper side of the locking device, by the intermediary of an arched wall 14, whereby an approximately U-shaped cross section will be imparted to the hood.
• Inwardly directed portions 15 and 16 are dis ⁇ posed along the under edges of both of the side walls 12 and 13, and may be accommodated in the two elongate spaces 9 and 10 between the bottom face 2 and the under idges 8 of the end pieces 6 and 7.
• the hood 11 will be shiftable in its longitudinal dir ⁇ ection interiorly between the two side edges 3 and 4 of the base portion 1.
• the widths of the two elongate spaces 9 and 10 are different at the two ends of the locking device.
• the width is less at the right-hand end of the locking device, as shown in Figs. 2 and 3, than at the left- hand end of the locking device.
• Abutment members, or shoulders, 17 and 18 are disposed between these portions of different width of the two elongate spaces 9 and 10, the abutment members being suit- ably located, in the longitudinal direction of the locking device, beneath the guide member.
• abut ⁇ ment members (not shown on the Drawings) in both of the 3 inwardly directed portions 15 and 16, so that the hood 11 is there ⁇ by prevented from being shifted further in a direction to the right than is apparent from Fig. 1, in that the abutment members disposed on the hood enter into abutment with the abutment members 17 and 18 disposed on the spacer 5.
• the hood can be slid off from the bottom portion 1, in the open state of the lock ⁇ ing device, and be slid into the position illustrated in Fig. 1.
• the hood cannot, naturally, be shifted in any other direction, because of the cooperation between the side edges 3 and 4, the side walls 12 and 13 and the two inwardly directed portions 15 and 16, the bottom portion 2 and the under edges 8 of the guide member, as well as further details 23-25 in the other end of the locking device.
• the design of the guide member will be described in greater detail with reference to Figs. 2-4. It will thus be apparent that the guide member has a bottom 19 from which the two end pieces 6 and 7* are upwardly bent approximately at right angles.
• the guide member has two lower side walls 20 and 21, these being -also upwardly bent from the bottom 19.
• the side walls 20 and 21 are lo ⁇ cated in between the two end pieces 6 and 7, whereby these are sta ⁇ yed substantially in the longitudinal direction of the locking de ⁇ vice.
• the lower portidn of the guide member may be considered as a box which is placed on the upper face of the spacer 5.
• a through hole 22 is di ⁇ sposed centrally in the bottom 19 of the box, the hole also ex ⁇ tending through the spacer 5 and the base portion 1.
• the purpose of this hole 22 is to accommodate that screw, bolt or the like by means of which the locking device is anchored in a substrate.
• this screw or bolt may be in the form of a so-called carriage bolt and have the nut placed interiorly in the guide member, so that the nut will hereby, in the locked and closed state of the locking device, be completely enclosed and protected from tampering.
• the guide member is permanently fixed in the spacer 5, which, in its turn,*is permanently fixed in the base portion 1.
• This jointing can be effected by means of wel ⁇ ding, rivet connection, screw connection or the like. It should al- so be observed that that screw, bolt or the like which extends through the hole 22 improves the union of the above-mentioned de ⁇ tails.
• this extra hole may be in the form of a countersunk hole and may be placed in one or both of the two elongate spaces 9 and 10. Alternatively, this extra hole may be disposed straight through the spacer 5, in other words in the central portion of the locking device.
• the right-hand shank 24 has semi-rounded contour with the same configuration as the two end pieces 6 and 7 on the guide member. Further, this shank 24 has an opening 26, through which may be in- serted a key to a keyhole 27 in a locking cylinder 28 which is fix ⁇ edly screwed by means of a nut 29 into the other shank 23.
• the locking cylinder 28 has, in its left-hand end in Figs. 2 and 3, a protruding pin 30 which, under the action of a key in ⁇ serted in the keyhole 27, may be turned through 90°.
• a protruding pin 30 On the pro- truding pin, there is disposed an approximately rectangular bolt bar 31 which may possibly be slidable in the longitudinal direction of the protruding pin.
• the bolt bar 31 is rotatably disposed in the same plane as the plane of the inner end piece 7 and is moreover arranged to be moved into abutment against the right-hand side of this end piece in Figs. 2 and 3.
• 5 Fig. 6 shows an insert portion which is fixedly lockable in the locking device proper and which serves for the fixed retention of, for example, a chain.
• the in ⁇ sert portion has a U-shaped bent portion 33, from which extend two legs 34 and 35 which are parallel with one another
• the outer width between the two legs 34 and 35 corresponds substantially with the inner width between the two side walls 12 and 13 of the hood 11, this width also approximately corresponding to the outer width of the two end pieces 6 and 7 of the guide member, as well as the shank 24.
• the insert portion 32 will be insertable in its longitudinal direction interiorly in the hood 11.
• shoulders 36 and 37 which, on insertion of the insert portion into the hood 11, may come into abutment against the end edge of the hood.
• the physipal extent of these two shoulders in the width di ⁇ rection of the insert portion corresponds approximately to the ma ⁇ terial thickness of the side walls 12 and 13 of the hood, which en- " • ta'ils that the outer width of the bent portion of the insert por- tion approximately corresponds to the outer width of the hood 11.
• both end pieces 6 and 7 of the guide member have registering recesses 38 and 39. These re ⁇ Grandes are disposed in direct conjunction with the upper edges of the two side walls 20 and 21 on the guide member. Furthermore, the recesses 38 and 39 are dimensioned in such a manner that they can accommodate, substantially without play, the legs 34 and 35 of the insert portion 32, so that the insert portion may thereby be passed into the guide member to a position shown by broken lines in Fig. 2. If one imagines the hood 11 mounted on the locking device as it is shown in Fig. 2, the inside of the hood will abut against the outer sides of both legs 34 and 35, against the edges of the end pieces 6 and 7 and against the shank 24.
• the hood cannot be shifted in a direction to the right in Fig. 2, since, in such an instance, the shoulders disposed on the inwardly directed portions 15 and 16 of the hood will come into abutment against both of the shoulders 17 and 18 disposed on the spacer 5. Furthermore, the left-hand end edge of the hood in Fig. 2 will come into abutment against the shoulders 36 and 37 on the insert portion 32. This entails that if the insert portion 32 is held fixedly locked in the locking device, the insert portion will prevent left- ward shifting of the hood 11. Correspondingly, the hood 11 is pre ⁇ vented from rightward shifting by cooperation with the shoulders 17 and 18.
• the insert portion 32 at the ends of both legs 34 and 35, has recesses 40 and 41 which are placed in such a manner in the longitudinal direction of the legs that they are located on the right-hand side of the end piece 7 in Fig. 2 when the shoulders 36 and 37 abut against the end edge of * the hood 11, the hood 11 being, in its turn, arrested in. its right ⁇ ward movement towards the shoulders 17 and 18. If, in this pos- ition, the bolt bar 31 is turned through 90° from the position shown in Fig. 2, such that both ends of the bolt bar enter into en ⁇ gagement with the recesses 40 and 41, withdrawal to the left of the insert portion 32 will be prevented.
• the insert portion 32 can withstand very powerful traction forces, since the bolt bar 31 supports against the outside of the end piece 7 and, moreover, both legs 34 and 35 of the insert portion 32 are very ac ⁇ curately shored and guided not only by the guide member but also by the hood 11.
• the insert portion 32 On mounting of the lock on a substrate, the insert portion 32 is first dismantled when the bolt bar 31 is set by means of the key in the position shown in Figs. 2 and 3. Removal of the insert por ⁇ tion 32 is, here, effected by being simply pulled out to the left. Thereafter, the hood 11 is shifted out of both of the elongate spaces 9 and 10, so that it is freely released from the rest of the locking device. In this position, the bottom portion 1 of the locking device can be screwed fast using a bolt which extends through the hole 22.
• the locking device After tightening of the nut placed 7 interiorly in the guide member - the nut thus being urged against the bottom 19 of the guide member - and after mounting of the ex ⁇ tra screws mentioned above, the locking device may be considered as fully mounted. Possibly, the nut placed interiorly in the guide member may be secured in relation to the bolt by means of centre- punching, a cotter pin or the like, or alternatively the nut may be of the self-locking type so that it will rotate with the bolt if the opposite end of the bolt were to be made accessible and ro ⁇ tated. Thus, once the locking device has been mounted on its sub ⁇ strate, the hood 11 is slid into place in a direction to the right in Figs.
• the locking device is ready for use and the insert portion 32 can, for example, be employed for fixedly locking a chain, which, in such an event extends with one link about the bent portion 33 of the insert portion.
• Fig. 7 shows a modified embodiment of the base portion 1.
• This embodiment may offer production-engineering advantages and possibly also superior strength qualities. It will be apparent from the Figure that the spacer 5 and the bottom face 2 are of one-piece manufacture, quite simply in that the bottom face has been given a corresponding longitudinal outward pressing. The two elongate spaces 9 and 10 and the and the upwardly directed side edges 3 and 4 of the bottom portion are also apparent from the Figure.
• the outer shank 24 may suitably be of one- piece manufacture with the base portion 1.
• the bottom piece 25 and the inner shank 23 will consist of a sep ⁇ arate detail which is fixed in the base portion.
• the outer shank is manufactured in that the base portion is pro ⁇ vided with a portion, projecting in the longitudinal direction of the locking device, this portion being bent up at right angles to the base portion. Also in this embodiment, it is important that both of the longitudinal spaces 9 and 10 extend throughout the 8 entire length of the locking device and hence also beyond the outer shank 24, which, to this end, suitably has recesses in conjunction with the upper face of the base portion.
• the guide portion can be manufactured in two separate parts in which the outer end piece 6 is of one-piece manu ⁇ facture with the base portion 1.
• the construction will, here, be fully analogous with that disclosed above for the outer shank 24.
• the spacer 5 in which the spacer 5 is of one-piece manufacture with the bottom portion, it may be more ap-
• analogous abutments or arrests may also be placed on both side edges 3 and 4, for example in that these have upper por- " tions inwardly bent towards one another and being parallel with the bottom face 2 of the base portion and being accommodatable in cor ⁇ responding recesses in both side walls 12 and 13 of the hood 11.
