Description
FIELD OF INVENTION This invention relates to a locking bolt assembly capable of being locked in place to prevent unauthorized removal or use of an article locked With the assembly. BACKGROUND OF THE INVENTION There are various anti-theft solutions available for example to prevent unauthorized removal of car Wheels. Some devices specif1cally meant for car Wheels are disclosed for example in the applicant"s previous patents US9,689,180 and US 10,486,461.
Anti-theft solutions to prevent access to a head of a locking bolt are disclosed in patent application publication GB2073298. This publication discloses a three- part locking bolt assembly, comprising a nut, a shroud and a key-operated lock. In this device a nose of the lock engages With the nut via a spring ring, and the lock has key-actuated detents engaging With the shroud. In DE3017879 a system is disclosed Where a locking bolt is provided With a cylindrical longitudinal bore having a radially extending groove into Which a corresponding outer contour of a key-operated lock attaches. Thus, in both of these approaches the lock is directly attached to the locking bolt. The problem With this kind of solution is that because they require the lock being directly attached to the locking bolt, the structures engaging the lock to the locking bolt may deteriorate upon long use and the lock no more is secure.
There are additionally various publications that disclose anti-theft or security -systems Where the operation is based on a nut having a specific geometric design matching to the bolt, and a socket key having a design matching to the nut design. Examples of such publications are US patent US 10612581 and international application WO0109527. With these type of solutions, the problem is a limited number of altemative designs. Maximally such systems can provide hundreds of individual designs and therefore there is an existing thread that two locks have same keys. Moreover, these locks are inherently not very secure in a sense that they can be pulled out by hammering a non-matching socket key on the nut.
Accordingly, there is a need for additional devices and method with practically unlimited number of alternative locking codes or keys to provide security. SUMMARY OF THE INVENTION In view of the above, an object of this invention is to provide a technology that addresses at least some of the above concerns. This and other objects, which will become apparent in the following, are accomplished by an assembly and a method defined in the claims.

BRIEF DESCRIPTION OF THE DRAWINGS Figure la illustrates the anti-theft locking bolt assembly installed to secure a car wheel in place. A lock cylinder 1 of the locking bolt assembly as well as the lock cylinder housing 4 are visible in the figure. The locking bolt assembly is installed through the rim to the hub of the car wheel thus preventing removal of the wheel without removing the locking bolt assembly first.
Figure l b illustrates an alternative use of the locking bolt assembly. Here, on the left side is illustrated a spark plug 9 attached onto a combustion engine. On the right-hand side, the spark plug has been replaced by the locking bolt assembly of the present disclosure. In the figure the anti-theft bolt 6, the lock cylinder 1, and the lock cylinder housing 4 are visible. The engine cannot be started without the spark plug and a new spark plug cannot be inserted before removing the locking bolt assembly.
Figure 2 illustrates an exploded view of the locking bolt assembly of this disclosure. The figure shows the lock cylinder 1, an attachment means 2 which in this embodiment is a counter sunk screw, the wheel bolt cap 3, the lock cylinder housing 4, the ball bearing 5, and the anti-theft bolt 6.
Figure 3 is a detailed drawing of the anti-theft bolt 6. The bolt has a substantially flat head portion 61 and an extemally threaded shaft 62. The flat head portion 61 comprises a center bore 66 having a non-circular perimeter 65. In this figure an embodiment is shown where a threaded inner channel 67 extends into to the shaft 62 and opens in the center of the bore 66. According to other embodiments the inner channel may not be threated. The substantially flat head portion 61 has at least one indentation 68 on its surface to adapt ball bearings. The indentations shown in this embodiment are half sphere indentations each adapted for one ball bearing.
The at least one indentation may equally well be a circular groove adapted for one or more ball bearings.
Figure 4 shows the bolt cap 3 in two perspectives. The upper view is a bottom view of the of the bolt cap and the lower view is a top view of the bolt cap. In each figure the bottom part 31 and the top part of the cap 32 is Visible. Both of the figures also show the non- circular perimeter 33 of the bottom part 31. The central hole 34 is shown in the bottom View. The top part 32 has a perimeter A-A larger than a perimeter B-B of the bottom part 31 and thus the top part forms a lip 36. The lip 36 of the top part 32 has at least one straight part 35 on its perimeter to allow the bolt cap 3 to be entered through the upper opening 44 of the housing (shown in figure 6) in only one way. The lip 36 also has a purpose to lock the bolt cap behind a lower inner edge 48 of the housing as shown in figure 8. There may be a middle part 37 between the top part 32 and the bottom part 31 as is shown in figure 4. The middle part forms an edge that rests against the flat surface of the anti-theft lock bolt as is Visible in figure 8.
Figure 5 shows a bottom View of the lock cylinder housing 4. In this embodiment, the lower end 41 of the housing has a circular grooVe 43 configured to adapt the ball bearings 5 (shown in figure 2). In another embodiment the lower end of the housing 41 is flat. Visible inside the lock cylinder housing is the slot 49 forming a lower inner edge 48 and upper inner edge 47.
Figure 6 shows the lock cylinder housing 4 with a View to the upper end 42 of the housing. The upper opening 44 has a shape such that the lock cylinder 1 and the bolt cap 3 fit through the hole only in one way, i.e. the opening has at least one flat surface 46 making the opening to haVe a shape matching with the shape of the lock cylinder and the bolt cap. The lock cylinder housing 4 has an outer edge 45 on which a head 12 of the lock cylinder 1 is resting as can be seen in from figure 8.
Figure 7 shows the lock cylinder 1 in locking position. The figure shows the flat surface of the lock 10 to allow the lock to be inserted into the lock cylinder housing 4 only one way when the lock cylinder is in unlocked position such that the flat surface of the lock 10 and the flat surface 46 of the upper opening of the housing match. The figure shows the stud 11 of the lock which can be tumed by a key of the lock. The lock cylinder 1 is locked into the lock cylinder housing 4 by operation of the key such that the stud 11 becomes blocked behind an upper inner edge 47 (Visible in figure 8) of the lock cylinder housing. The locking bolt of this inVention can be made with practically endless number of Variations depending on the length of the lock cylinder housing. The locking mechanism of a lock cylinder is generally based on a correct key aligning lock pins and allowing moVement of the key plug. Due to the combinatorics the pins within the lock cylinder can be arranged in X number of ways depending on the number of the pins.
Increasing the length of the cylinder allows adding more pins and the combinations will increase exponentially. In an exemplary embodiment using six pins about 66 000 combinations can be achieved. The number of combinations can be increased to over 8 million by increasing the length of the lock cylinder but still having a lock cylinder that is practicable for use.
Figure 8 shows a cross sectional view of the locking bolt assembly. The figure shows lock cylinder 1, the lock cylinder housing 4, the bolt cap 3, the anti-theft bolt 6 with the threaded outer surface. The figure shows a ball bearing 5 connecting the lock cylinder housing 4 onto the anti-theft bolt 6. The lock cylinder has a lock head 12 resting on the outer edge 45 of the lock cylinder housing. The lock stud 11 is blocked behind the upper inner edge 47 of the lock cylinder housing 4, and the lip 36 of the bolt cap is blocked behind the lower inner edge 48 of the lock cylinder housing 4.
DETAILED DESCRIPTION OF THE INVENTON An anti-theft locking bolt assembly is described here to prevent unauthorized removal or use of articles onto which the assembly is attached. The locking bolt assembly can be used for preventing unauthorized removal of car wheels (Figure la), but the locking bolt assembly is as well suitable for example in protection of a vehicle engine from being started when a spark plug is replaced by the locking bolt assembly (Figure lb). This can be used as an anti-theft device in preventing unauthorized use for example of boats.
The invention is now described in more details in reference to the embodiments shown in the drawings.
As is illustrated in Figure 2, the locking bolt assembly according to this disclosure comprises an anti-theft bolt 6, a cylindrical lock housing 4, a bolt cap 3 and a lock cylinder 1. As illustrated in Figure 4, the bolt cap has a bottom part 31 and a top part 32 and the bottom part has a noncircular perimeter 33. A central through hole 34 goes through the bottom and the top parts of the bolt cap. The top part 32 has a perimeter (A-A) larger than a perimeter (B-B) of the bottom part 31 thus forming a lip 36. The lip 36 of top part 32 has at least one straight part 35 on its perimeter to allow the bolt cap 3 to be entered through the upper opening 44 of the lock cylinder housing in only one way. The upper opening of the lock cylinder housing is shown in figure 5.
The lip 36 also has a purpose to block the bolt cap behind a lower inner edge 48 of the housing as shown in figure 8.
Figure 3 shows the anti-theft bolt 6 in more details. The anti-theft bolt has an external threading 63 on its shaft 62 and the threading is conf1gured to mate with a threading in the article to which the bolt is to be attached, e.g., threading of a wheel hub, or threading in a spark plug lot in an engine. The head 61 of the anti-theft bolt has a generally flat upper surface 64 (in this context generally flat means that the head surface is not generally concaVe or conVex). In the center of the flat surface there is a center bore 66 that has a non-circular perimeter 65. The non-circular pattern of the perimeter of the bore matches the non-circular pattern of the bolt cap perimeter 33 (shown in Figure 4) such that the bottom part 31 of the bolt cap snugly f1ts into the bore 66 of the bolt head. Fitting snugly, means here that the perimeter of the bottom part of the bolt cap is in contact with the perimeter of the bore substantially from their full lengths, thus substantially preVenting horizontal moVement of the bottom part within the bore.
As shown in Figure 3, the generally flat surface of the bolt head has at least one indentation 68 around the center bore 66. According to one embodiment, such as shown in figure 3, there are seVeral half sphere indentations, and each is adapted for one ball bearing. The number of indentations may Vary. According to some embodiments the at least one indentation is a circular grooVe adapted for one or more ball bearings.
The bolt cap 3 is attached onto the anti-theft bolt with attaching means. Preferably the attaching means is a screw 2 that is attached threadedly into the threaded inner channel 67 of the shaft 62 of the anti-theft bolt. The inner channel preferably opens into bottom of the center bore 66. In another embodiment the attaching means is at least one pin that is conf1gured to attach inside the channel of the shaft. When the attaching means is a pin, the inner channel 67 does not need to be threaded. The channel does not need to open to the center of the bore. Figure 3 shows an embodiment where the inner channel 67 inside the shaft 62 is threaded and the means to attach the bolt cap to the bolt is Via a screw 2 (shown in f1gure 2) that has threading matching the inner threading of the inner channel 67.
Figures 5 and 6 illustrate the structure of the lock cylinder housing 4 that is conf1gured to cover the anti-theft bolt 6 and the bolt cap 3, and to connect to the lock cylinder 1 and to the bolt cap 3 which is attached to the anti-theft bolt 6. The lock cylinder housing 4 has a lower end 41 and an 7 upper end 42. The lower end preferably has a circular groove 43 conf1gured to adapt one or more ball bearings 5 that are inserted into the one or more indentations 68 of the anti-theft lock 6. The ball bearings 5 allow the lock cylinder housing 4 to tum on top of the anti-theft bolt 6, thereby providing an additional security feature as preventing turning of the anti-theft bolt by turning the housing.
The groove 43 is optional, and in another embodiment the lower end 41 of the housing is flat. In this embodiment the lock cylinder housing 4 is also turning on top of the anti-theft bolt 6, now only the ball bearings 5 roll on the lower flat edge of the lock cylinder housing 4.
Figure 8 shows a cross sectional view of the device when assembled and the location of the ball bearings 5 can be seen between the flat surface of the anti-theft bolt and the lower end of the housings.
The upper opening 44 of the lock cylinder housing 4 has at least one flat surface 46. The flat surface enables insertion of the lock cylinder 1 as well as the bolt cap 3 in only one position such that the flat surface 10 of the lock cylinder 1 or the straight part 35 of the perimeter of the top part of the bolt cap slides along the flat surface 10 of the housing. Behind the flat surface 44 (meaning here into direction toward the lower end of the lock cylinder housing) there is at least one slot 49 into which the stud 11 can be tumed. The at least one slot 49 has an upper inner edge 47 and a lower inner edge 48 and the at least one slot is used to block both the lock cylinder 1 and the bolt cap 3 in their place: Figure 8 shows the lock stud 11 is blocked by upper inner edge 47 of the slot and the lip 36 of the is blocked by the lower inner edge 48 of the slot. Thus, when the anti-theft lock assembly is in locked position, the lock cannot be removed from the lock cylinder housing because the stud is blocked by the upper inner edge. The cylinder housing cannot be removed, because the lower inner edge is blocked by the lip of the bolt cap and the bolt cap is attached to the antitheft bolt 6 which again is threated to the article to be protected. The ball bearing connection between the anti-theft bolt 6 and the lock cylinder housing 4 prevents any kind or tuming of the anti-theft bolt because the lock cylinder housing is rotating freely on the ball bearings. Accordingly, the anti-theft locking bolt assembly provide multiple layers of protections.
This enables assembly of the bolt lock in its place such that after the anti-theft lock is attached and the ball bearings are inserted into the at least one indentation, the lock housing is connected to the anti-theft lock, after Which the bolt cap is inserted through the upper opening of the housing and due to the matching shape of the upper opening and the top part of the bolt cap, the bolt cap goes through the housing in one position only, Which position is such that the non- circular shape of the bottom part of the bolt cap automatically matches With the non-circular shape of the bore of the anti-theft bolt.
The assembly disclosed here has multitude of locking combinations depending on length of the lock cylinder. Preferably the assembly has at least 60 000 different combinations. The assembly may have 100 000 different combinations, 200 000 combination and even up to 8 million combinations. Accordingly, the assembly disclosed and claimed here provides a remarkable improvement as compared to any existing devices in the security.
Other variations to the disclosed embodiments can be understood and effected by those skilled in the art in practicing the claimed invention, from a study of the draWings, the disclosure and the appended claims. In the claims, the Word "comprising" does not exclude other elements or steps, and the indef1nite article "a" or "an" does not exclude a plurality. The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage. Any reference signs in the claims should not be construed as limiting the scope.
