“A modular multipoint locking assembly”
Introduction
This invention relates to a modular multipoint locking assembly and a method of installing the modular multipoint locking assembly.
Multipoint locking assemblies are used to secure ope closures such as doors and windows in position in an ope. Cams are used in the multipoint locking assembly to create compression points. The compression points provide an even seal and avoid gaps forming around the ope closure. There are a number of factors taken into account when determining the correct number and location of compression cams for a given application. For example, the material, the design and the purpose of the ope closure as well as customer preference all dictate the required cam configuration. If a multipoint locking assembly with the desired configuration of compression cams is not in the existing product range, a bespoke multipoint locking assembly will have to be manufactured for the customer or the customer will have to settle for a multipoint locking assembly with a sub-optimal compression cam configuration from the existing product range.
Due to the large number of factors that must be taken into consideration when selecting the multipoint locking assembly with an appropriate configuration of compression cams, manufacturers are required to produce an extensive range of multipoint locking assemblies with various configurations of compression cams. Accordingly, the manufacturers must also have an extensive inventory and substantial storage space to stock the inventory. These cause a financial drain on the manufacturer. Additionally, installers of multipoint locking assemblies are also required to stock an extensive inventory in their vans and premises in an effort to ensure that they have a multipoint locking assembly with a compression cam configuration that meets with the customer’s needs. This represents a financial drain on the installer and limits the amount of space available for other equipment. If a customer requires a multipoint locking assembly with a compression cam configuration that is not part of the manufacturer’s inventory, a bespoke multipoint locking assembly must be manufactured to order. This can be very expensive for the customer and can take a significant amount of time to produce.
-2Generally speaking, current multipoint locking assemblies incorporate two to four cams, which are riveted in a fixed location on the drive rod of the multipoint locking assembly. If the multipoint locking assembly is found to be inadequate after installation, for example due to the ope closure warping, swelling or contracting over time and requiring compression cams in other locations, the entire multipoint locking assembly must be removed and replaced with a new multipoint locking assembly with the required configuration of compression cams. This is laborious and expensive.
It is an object of the present invention to provide a modular multipoint locking assembly that overcomes at least some of the problems with known multipoint locking assemblies. It is a further object of the present invention to provide a modular multipoint locking assembly that offers a useful choice to the consumer.
Statements of Invention
According to the invention there is provided a modular multipoint locking assembly for an ope closure comprising a face plate, a plurality of locking members, and a drive rod slidably mounted for reciprocal movement back and forth along the face plate, characterised in that the drive rod is provided with a plurality of mounting points each of which is capable of receiving a compression cam, the face plate is provided with a plurality of elongate slots corresponding to the mounting points for through passage of the compression cam, and in which there is provided at least one compression cam separate from the remainder of the assembly for selective placement in one of the mounting points in the drive rod.
By having such a modular multipoint locking assembly, compression cams can be placed on a drive rod in accordance with a customer’s specifications. This obviates the need for manufacturers to produce and supply an extensive range of multipoint locking assemblies, thereby decreasing production costs and decreasing the amount of space required to store the multipoint locking assemblies. Additionally, installers of the modular multipoint locking assemblies are also no longer required to stock an extensive inventory of multipoint locking assemblies in their vans and premises, which can provide the installer with more space in their van for other equipment and reduces operation costs.
- 3Furthermore, by having such a modular multipoint locking assembly, if the modular multipoint locking assembly is found to be inadequate after installation, the configuration of compression cams can be modified to satisfy the new requirements without replacing the entire multipoint locking assembly.
In one embodiment of the invention there is provided a modular multipoint locking assembly in which there are provided a plurality of compression cams separate from the remainder of the assembly, each for selective placement in one of the mounting points in the drive rod.
In one embodiment of the invention there is provided a modular multipoint locking assembly in which the compression cam is releasably secured to the mounting point in the drive rod. By having such an assembly, the compression cam can be repositioned if desired. In this way, if the ope closure warps over time, the position of the compression cam can be adjusted accordingly.
In one embodiment of the invention there is provided a modular multipoint locking assembly in which the compression cam is provided with means to permanently secure the cam in the mounting point in the drive rod. By having such an assembly, inadvertent release of the compression cam from the mounting point will be prevented.
In one embodiment of the invention there is provided a modular multipoint locking assembly in which the compression cam has a threaded portion for engagement of a complementary threaded portion of the mounting point in the drive rod.
In one embodiment of the invention there is provided a modular multipoint locking assembly in which the compression cam has a bayonet fitting for engagement of a complementary bayonet fitting receiver of the mounting point in the drive rod.
In one embodiment of the invention there is provided a modular multipoint locking assembly in which the compression cam has a screw drive receiver head. By having such a screw drive receiver head, the compression cam can be securely affixed to or easily removed from the mounting point in the drive rod.
-4In one embodiment of the invention there is provided a modular multipoint locking assembly in which the compression cam has a cylindrical sleeve.
In one embodiment of the invention there is provided a modular multipoint locking assembly in which the compression cam has a mushroom-shaped head.
In one embodiment of the invention there is provided a modular multipoint locking assembly in which there is provided an adhesive to secure the compression cam in place in the mounting point of the drive rod.
In one embodiment of the invention there is provided a modular multipoint locking assembly in which the plurality of mounting points are spaced evenly along the length of the drive rod.
In one embodiment of the invention there is provided a modular multipoint locking assembly in which the mounting point is located no further than 0.15 metres from a locking member.
In one embodiment of the invention there is provided a modular multipoint locking assembly in which the longitudinal sides of the drive rod adjacent the end of the drive rod are provided with serrated teeth. By providing serrated teeth at the ends of the drive rod, the drive rod can be fitted with extension pieces.
In one embodiment of the invention there is provided a method of installing a multipoint locking assembly as claimed in an ope closure comprising the steps of:
selecting where on the drive rod of the multipoint locking assembly it is desired to place a compression cam; and the installer affixing the compression cam to the drive rod in the appropriate mounting point in the desired location along the drive rod.
This is seen as a particularly effective method of installing a multipoint locking assembly. By allowing the installer to select where on the drive rod of the multipoint locking
- 5assembly that they wish to place the compression cam and thereafter allowing the installer secure the compression cam in the desired location on the drive rod, it will be possible to provide the precise configuration of multipoint locking assembly cams required by the customer. This is achieved without the manufacturer having to manufacture and store a large inventory of multipoint locking assemblies and without the installer having to maintain a large inventory.
In one embodiment of the invention there is provided a method of installing a multipoint locking assembly comprising the additional step of securing the multipoint locking assembly to the ope closure prior to affixing the compression cam to the drive rod. In this way, the majority of the multipoint locking assembly can be in situ prior to the compression cam(s) being fitted. This will allow the installer to visually assess precisely where the cam(s) will be located in relation to the ope closure.
In one embodiment of the invention there is provided a method of installing a multipoint locking assembly comprising the additional step of affixing the compression cam to the drive rod prior to securing the multipoint locking assembly to the ope closure. This method has the advantage that the assembly will be easier to install into an ope closure as the entire assembly can be inserted into the ope closure as a single piece. Furthermore, if there are regulatory requirements specifying that the compression cams must be within a certain distance from a locking member, it will be easier to measure this distance and ensure that the compression cams are within that distance if the compression cams are mounted prior to the multipoint locking assembly being installed in the ope closure.
In one embodiment of the invention there is provided a method of installing a multipoint locking assembly comprising the additional step of affixing an additional compression cam to the drive rod subsequent to securing the multipoint locking assembly to the ope closure. In this way, if it is necessary to add one or more compression cams to the multipoint locking assembly over time, for example due to swelling, contraction or warping of the ope closure, it can be achieved with relatively little difficulty.
-6In one embodiment of the invention there is provided a method of installing a multipoint locking assembly comprising the step of the installer detaching a compression cam from the drive rod.
In one embodiment of the invention there is provided a method of installing a multipoint locking assembly comprising the step of the installer putting an adhesive on one of the compression cam and the mounting point prior to inserting the compression cam in the mounting point in order to permanently secure the compression cam in the mounting point.
Detailed Description of the Invention
The invention will now be more clearly understood from the following description of some embodiments thereof given by way of example only with reference to the accompanying drawings, in which:Figure 1 is a side view of a modular multipoint locking assembly in a locked configuration according to the invention;
Figure 2 is a front view of the modular multipoint locking assembly as shown in Figure 1;
Figure 3 is a side view of the modular multipoint locking assembly in an unlocked configuration;
Figure 4 is a front view of the modular multipoint locking assembly as shown in Figure 3;
Figure 5 is an enlarged view of the circled portion of Figure 1;
Figure 6 is an enlarged view of the circled portion of Figure 2; and
- 7Figure 7 is a perspective view of part of a modular multipoint locking assembly according to the invention.
Referring to Figures 1 to 4, there is shown a modular multipoint locking assembly, indicated generally by the reference numeral 1. The modular multipoint locking assembly comprises a face plate 3, three locking members 5, 7, and 9 located adjacent the top, middle and bottom of the face plate 3 respectively, and a drive rod 11 slidably mounted on the face plate 3 for reciprocal movement back and forth along the face plate 3. There is further provided a pair of compression cams 13 secured in mounting points 15 positioned along the drive rod 11 and a plurality of elongate slots 17 corresponding to the mounting points 15 for through passage of the compression cams 13. Each of the locking members 5, 7 and 9, has a locking hook 19 and the locking member 7 further comprises an aperture 21 for a cylinder lock (not shown), a spindle receiver 23 for affixing a handle and a spring latch 25 for engaging the modular multipoint locking assembly with the ope frame (not shown).
Referring specifically to Figures 1 and 2, the modular multipoint locking assembly is shown in a locked configuration with the locking hooks 19 deployed. Referring specifically to Figures 3 and 4, the modular multipoint locking assembly 1 is shown in an unlocked configuration. In the unlocked configuration, the locking hooks 19 are housed within the locking members 5, 7 and 9.
In use, the drive rod 11 is manipulated by the locking member 7 such that when a key (not shown) is turned in the cylinder lock (not shown) of locking member 7, the drive rod moves in a reciprocal fashion back and forth along the face plate. The drive rod is in fact a multi-part rod. When the key is turned in the cylinder lock of locking member 7 to lock the assembly, the parts of the drive rod will move outwardly away from the central locking member 7. In other words, the parts of the drive rod will move away from the central locking member towards the nearest free end of the face plate. When the key is turned in the cylinder lock of the locking member 7 to unlock the assembly, the parts of the drive rod will move back inwardly towards the central locking member 7, away from the nearest free end of the face plate.
- 8Referring once again to Figures 1 and 2, the key has been rotated in the cylinder lock of the locking member 7 to lock the assembly. In doing so, the locking hooks 19 are moved to a locking position external the locking members 5, 7 and 9 where they may each engage a corresponding receiver (not shown). The parts of the drive rod 11 are driven outwardly away from the locking member 7 towards the nearest free end of the face plate 3. The compression cams 13 mounted on the drive rod 11 are driven along the elongate slots 17 by the drive rod 11. It can be seen in Figure 2 that in a locked configuration, the compression cams 13 are positioned at the outermost end of the elongate slot 17 relative to the centre of the face plate 3. Referring now to Figure 4, in an unlocked configuration, the compression cams 13 are located at the innermost end of the elongate slot 17 relative to the centre of the face plate 3.
When the multipoint locking assembly is “locked” the locking hooks 19 will engage complementary receivers in an ope frame (not shown). Similarly, the compression cams will be moved from a position free of a complementary receiver on the ope frame to a position engaging the complementary receiver on the ope frame. When the multipoint locking assembly is “unlocked” the locking hooks 19 will release the complementary receivers in the ope frame and the compression cams will be moved from a position engaging the complementary receiver on the ope frame to a position free of the complementary receiver.
In the embodiment described above, the drive rod 11 is driven along the face plate 3 by rotating a key in the cylinder lock of the locking member 7. It will be understood that the drive rod 11 can also be handle operated such that by turning a handle (not shown) located in the spindle receiver 23, the drive rod 11 is driven along the face plate 3 by the handle.
Referring now to Figure 5, there is shown an enlarged view of the circled portion of Figure 1. A double-headed arrow A indicates the reciprocal fashion relative to the face plate 3 that the drive rod 11 may move when actuated by the locking member. The compression cam 13 mounted on the drive rod 11 has been moved away from the locking member 5 along the face plate in the direction of arrow B upon “locking” of the multipoint locking assembly.
- 9Referring now to Figure 6, there is shown an enlarged view of the circled portion of Figure 2. The locking hook 19 is shown out of the locking member 9 in a locked configuration. More importantly, a compression cam 13 is shown located at the outermost end of the elongate slot 17 nearest to the locking member 9. Furthermore, there is shown a mounting point 15 without a compression cam mounted therein that is accessible through the elongate slot 17 furthest from the locking member. It will be understood that the compression cam 13 could have been mounted in the free mounting point 15 in the other elongate slot. Alternatively, a pair of compression cams could be mounted on the drive rod, one passing through each of the elongate slots 17. Although it has been described that each locking member has a locking hook housed therein for engagement of a complementary receiver in an ope frame, it is envisaged that a deadbolt could be used instead of the locking hook.
In addition to the foregoing, the compression cam 13 has a screw drive receiver head 27 to receive a screw driving means (not shown) for affixing or removing the compression cam 13 from the mounting point of the drive rod. It will be understood that a range of screw drive receiver heads could be used, including, but not limited to, hex, slot, Phillips, star or 12-point screw drive receiver heads. The compression cam 13 shown is a roller cam with an external sleeve 28 that is free to rotate about an internal core. Alternatively, a mushroom headed compression cam could be used instead. The mushroom headed compression cam is deemed suitable for more secure applications.
It is envisaged that in a preferred embodiment of the present invention, a number of disparate types and sizes of cam may be provided in a separate kit. Thereafter, the installer of the modular multipoint locking assembly may select the appropriate compression cams on site and insert those compression cams into the mounting points 15 of the drive rod in the desired locations during installation or servicing of the ope closure.
Referring now to Figure 7, there is shown a perspective view of a section of the modular multipoint locking assembly 1. There is clearly shown a mounting point 15 for receiving a compression cam 13. An arrow C indicates the directions in which the drive rod 11 and by extension the compression cam 13 mounted in the mounting point 15 on the drive rod 11 may move. The drive rod 11 has serrated teeth for the addition of extension pieces
- 10(not shown). The compression cam 13 has a threaded portion 29 for screwing into a complementary threaded portion 31 of the mounting point 15 on the drive rod 11. The compression cam 13 further comprises a collar 33 intermediate the sleeve 28 and the threaded portion 29 to prevent friction between the compression cam 13 and the face plate 3 when the compression cam 13 is driven along the elongate slot 17. It will be understood that the affixing means of the compression cam 13 and mounting point 15 is not limited to that of a screw threaded type. It will be understood that alternative means could be used to secure the compression cam in position. These include, but are not limited to, providing a push-fit inner end to the compression cam, providing a springloaded inner end to the compression cam, providing a bayonet or similar fitting. The compression cam may be secured in place relative to the drive rod with glue or indeed the threaded portion of the compression cam 13 or the mounting point 15 may be deliberately damaged in the process of insertion of the compression cam so that the compression cam 13 cannot be removed from the mounting point 15 without cutting the compression cam off. It will be further understood that as an alternative to a multi-part drive rod having bi-directional cams (i.e. some of the cams will move upwardly and some of the cams will move downwardly when transitioning to a locked configuration and the cams will move in the opposite direction when transitioning to an unlocked configuration) secured in mounting points on the drive rod as shown in Figures 1-4, it is envisaged that the drive-rod may comprise one piece. By having a one-piece drive rod, the movement of the cams secured in the mounting points on the drive-rod would be uni-directional (i.e. all of the cams will move in the same direction when the locking assembly is transitioned to a locked configuration and in the other direction when the locking assembly is transitioned to an unlocked configuration).
In this specification the terms “comprise, comprises, comprised and comprising” and the terms “include, includes, included and including” are all deemed totally interchangeable and should be afforded the widest possible interpretation.
The invention is in no way limited to the embodiment hereinbefore described but may be varied in both construction and detail within the scope of the claims.
