Description

[0001] The present invention relates to a mounting kit for a manual control device of a lock for a window or door, a manual control device formed with the components of said kit, and a window or door that features such a manual control device.

[0002] Known devices of this type usually include a handle from which a bushing extends through a through-hole in a handle mounting block attached to the frame profile.

[0003] The bushing has an axial channel where a square pin for lock operation is fitted.

[0004] In some known market solutions, an indexing ring for the angular position of the handle is attached to the bushing.

[0005] In these known solutions, the bushing is made as a single piece with the handle neck. These solutions are described, for example, in EP 4 069 921 A1.

[0006] While these known solutions offer ease of assembly, they may suffer from limited flexibility in use.

[0007] The technical task of the present invention is therefore to eliminate the technical drawbacks found in the known art.

[0008] In the context of this technical task, an objective of the invention is to provide a kit that allows for the assembly of a manual control device for a lock on a window or door in an extremely easy and fast way.

[0009] Another objective of the invention is to provide a kit that enables product diversification without complicating warehouse logistics. Another objective of the invention is to provide a kit that makes it possible to diversify the product while limiting the variety of components stored in the warehouse.

[0010] The technical task, as well as these and other objectives, according to the current invention, are achieved by a mounting kit for a manual control device of a lock for a window or door, comprising a handle, a box-shaped block for mounting the handle on a window or door profile, a bushing, a square pin, and a ring that can be engaged in rotation with said bushing and externally features means for indexing the angular position of the handle, wherein the handle has a grip and a neck with a housing, the box-shaped block has a through-hole for positioning said bushing and elastic means for feedback on said indexing means, and said bushing is made of a single block with an open axial channel for fitting the square pin, front guiding means for inserting a front portion of the bushing into the housing in the handle neck, rear snap-fit engagement means for attaching a rear portion of the bushing to said ring, anti-rotation means for the front portion of the bushing in the housing of the handle neck, and anti-extraction means for the front portion of the bushing from the housing in the handle neck, including at least one external axial groove on said bushing that can be coupled to an axial groove in said housing in the handle neck to cooperatively define a cylindrical seat for a locking screw.

[0011] In one embodiment of the invention, the rear snap-fit engagement means include external impressions on said bushing for engagement with internal snap-fit teeth on said ring.

[0012] In one embodiment of the invention, a series of said angularly offset impressions extend along arcs of a circumference.

[0013] In one embodiment of the invention, the rear portion of said bushing has a faceted outer surface matched in shape to an inner surface of said ring, from which said snap-fit teeth protrude.

[0014] In one embodiment of the invention, said impressions are made on said faceted outer surface.

[0015] In one embodiment of the invention, said front guiding means include an external flange on said bushing, shaped to match the shape of said housing in the handle neck.

[0016] In one embodiment of the invention, said anti-rotation means include external radial protrusions on said bushing that can be engaged in conjugated slots provided in said housing in the handle neck.

[0017] In one embodiment of the invention, said bushing includes a reduced diameter section from which said guiding means, anti-rotation means, and anti-extraction means extend in projection.

[0018] In one embodiment of the invention, the reduced-diameter section of the bushing features axial reinforcement ribs.

[0019] The present invention also relates to a manual control device assembled with such a mounting kit and to a window or door featuring such a manual control device.

[0020] Advantageously, the mounting kit allows the replacement of only the handle with another of a different shape or finish according to personal preferences.

[0021] Inventory management is improved since the same bushing is compatible with multiple versions of handles, which only need to have a standardized housing size in the handle neck.

[0022] Moreover, it is possible to update the product and expand or diversify its functionality by keeping the same handle and replacing the bushing with a different type, which in turn only needs to be dimensionally compatible with the housing in the handle neck.

[0023] Assembly does not require special tools and can even be done entirely by hand by forcing the bushing into the hole of the mounting block until the snap-fit engagement means click into place. The bushing can house at least one friction ring, which has a shape-fitting connection with the square pin to stabilize and adjust the engagement position of the square pin in the housing of the handle neck.

[0024] Advantageously, the length of the portion of the square pin protruding from the bushing can be adjusted by forcing the square pin to slide through the friction ring, which then firmly holds the square pin in the achieved position.

[0025] Therefore, a single-length square pin can be compatible for installation on a variety of windows. The installer will adjust the square pin's position directly on-site as needed.

[0026] The limit for adjusting the square pin's position is determined by the interference of the square pin's end with the bottom of the housing in the handle neck.

[0027] Further features and advantages of the invention will become more apparent from the description of a preferred but not exclusive embodiment of the mounting kit for the manual control device of a lock for a window or door, according to the invention, illustrated by way of example and not limitation in the attached drawings, in which: Figures 1 and 2 show an exploded view of the kit from two opposite perspectives; Figure 3 shows a front view of the manual control device; Figure 4 shows a side elevation view of the manual control device, sectioned along plane A-A of Figure 3; Figure 5 shows a bottom plan view of the manual control device; Figure 6 shows a side elevation view of the manual control device, sectioned along plane E-E of Figure 5; Figures 7 and 8 show the bushing of the manual control device from two opposite perspectives; Figure 9 shows a perspective view of the ring of the manual control device; Figure 10 shows a front view of the ring of the manual control device; Figure 11 shows a side elevation view of the ring of the manual control device, sectioned along plane F-F of Figure 10.

[0028] In the following, the terms "front," "rear," "in front," and "behind" are to be understood with reference to an observer facing the manual control device installed on the frame.

[0029] Referring to the mentioned figures, a kit for the assembly of a manual control device for a lock of a window or door is shown.

[0030] The kit includes a handle 1, a box-shaped block 2 for mounting the handle 1 on a window or door profile, a bushing 3, a square pin 4, and a ring 5 that can be rotationally engaged with the bushing 3 and externally features means for indexing the angular position of the handle. The handle 1 has a grip 6 and a neck 7 equipped with a housing 8.

[0031] The box-shaped block 2 has a through-hole 9 through which the bushing 3 can be inserted, as well as elastic means for feedback on the indexing means.

[0032] The box-shaped block 2 also has screw holes 31 for screws (not shown) to attach it to the window or door profile.

[0033] The mounting kit includes a cover 32 that can be applied to the box-shaped block 2 to cover the screw holes 31.

[0034] The bushing 3 is made of a single block that features an open axial channel 10 for fitting the square pin 4, front guiding means for inserting a front portion of the bushing 3 into the housing 8 in the neck 7 of the handle 1, rear snap-fit engagement means for securing a rear portion of the bushing 3 to the ring 5 when the ring is slid onto the bushing 3 behind the hole 9, anti-rotation means for the front portion of the bushing 3 in the housing 8 in the neck 7 of the handle 1, and anti-extraction means for the front portion of the bushing 3 from the housing 8 in the neck 7 of the handle 1. The square pin 4 has a rear end for engaging with a movement-transmitting seat provided in the lock (not shown).

[0035] The rear snap-fit engagement means include external impressions 11 on the bushing 3 for engagement with internal snap-fit teeth 12 on the ring 5.

[0036] The impressions 11 are angularly offset and extend along arcs of a circumference centered on the axis of the bushing 3.

[0037] The rear portion of the bushing 3 has a faceted external surface 13 shaped to match an internal surface 14 of the ring 5, from which the snap-fit teeth 12 protrude inward.

[0038] The impressions 11 are made on the faceted external surface 13 of the rear portion of the bushing 3.

[0039] The front guiding means include an external flange 15 on the bushing 3, shaped to match the housing 8 in the neck 7 of the handle 1.

[0040] The anti-rotation means include external radial protrusions 16 on the bushing 3, which can engage with conjugate slots 17 provided in the housing 8 in the neck 7 of the handle 1.

[0041] The anti-extraction means include at least one external axial groove 18 on the bushing 3, which can be coupled with an axial groove 19 provided in the housing 8 in the neck 7 of the handle 1, cooperatively defining a cylindrical seat for a locking screw 40.

[0042] The bushing 3 includes a reduced-diameter section 20 from which the guiding means, anti-rotation means, and anti-extraction means project.

[0043] The reduced-diameter section 20 of the bushing has axial reinforcement ribs 21.

[0044] The box-shaped block 2 has a front wall 22 where the through-hole 9 is made and a lateral frame 23 that extends perimetrically and rearward from the front wall 22, enclosing an annular wall 24 that surrounds the rear side of the through-hole 9.

[0045] The ring 5 has a cylindrical front portion 25 with a smaller diameter and a cylindrical rear portion 26 with a larger diameter, connected by an annular shoulder 27.

[0046] The inner lateral surface of the annular wall 24 serves as a rotational guide for the front cylindrical portion 25 of the ring 5, which has a smaller diameter, while the rear edge of the annular wall 24 acts as a stop for the annular shoulder 27.

[0047] The front cylindrical portion 25 of the ring 5, with its smaller diameter, has an internal faceted surface 14 that is conjugate in shape with the external surface 13 of the bushing 3.

[0048] In this way, the ring 5 can be rotationally locked to the bushing 3.

[0049] The external surface of the rear portion 26 of the ring 5 features radial recesses 28 that engage with corresponding elastically flexible radial protrusions 29 supported by the housing block 2.

[0050] The radial recesses 28 on the external surface of the rear portion 26 of the ring 5 form the indexing means for the angular position of the handle 1, while the radial protrusions 29 act as elastic engagement means for the indexing mechanism.

[0051] The assembly kit also includes a friction ring 30 that can be secured to the rear end of the axial channel 10 of the bushing 3.

[0052] The friction ring 30 is made of rubber or any other material providing an adequate friction coefficient with the material of the square spindle 4.

[0053] For example, a friction ring 30 made of silicone rubber has been found suitable for use in combination with a square spindle 4 made of steel or iron.

[0054] The device 1 is assembled along an assembly axis L, along which the central geometric axes of the housing 8 in the neck 7 of the handle 1, the bushing 3, the hole 9 in the block 2, and the ring 5 must be aligned.

[0055] First, the bushing 3 is fixed in the housing 8 in the neck 7 of the handle 1.

[0056] To do this, the front portion of the bushing 3 is inserted into the housing 8 in the neck 7 of the handle 1, ensuring beforehand that the protrusions 16 are axially aligned with the slots 17, and the groove 18 is aligned with the groove 19 to properly engage the protrusions 16 in the slots 17 and overlap the grooves 18 and 19.

[0057] Then, the locking screw is tightened in the cylindrical seat formed by the overlapping grooves 18 and 19.

[0058] At this point, the ring 5 is positioned from the rear side of the box-shaped block 2 by sliding its front portion 25 along the inner lateral surface of the annular wall 24 until the annular shoulder 27 engages the edge of the rear end of the annular wall 24.

[0059] Next, while the ring 5 is held axially in the achieved position using a specific pusher (not shown), the bushing 3 is inserted into the hole 9 and the ring 5 from the front side of the box-shaped block 2.

[0060] As the bushing 3 begins its axial insertion, its rear portion engages the front portion of the ring 5. The axial insertion of the bushing 3 continues until the locking teeth 12 snap into the locking seats 11, thereby making the bushing 3 and the ring 5 axially fixed together.

[0061] At this point, the bushing 3 can no longer be retracted axially and removed from the hole 9 due to the blocking effect exerted on the shoulder 27 by the edge of the rear end of the annular wall 24. The end of the axial insertion of the bushing 3 is defined by the interference of the base of the neck 7 of the handle 1 against a front collar 34 of the cover 32, which surrounds a hole 35 in the cover designed for the passage of the bushing 3.

[0062] At this point, the friction ring 30 is positioned in the bushing 3, and pressure is applied to the handle 1 to force the square pin 4 through the friction ring 30 into the housing 8 in the neck 7 of the handle 1.

[0063] The extent of penetration into the neck 7 of the handle 1 depends on the type of window or door and, in particular, the distance between the lock and the control device.

[0064] After adjusting the position of the square pin 4, the mounting block 3 is fastened to the window or door profile with screws.

[0065] In use, the user perceives the achievement of the operational positions of the handle 1 (for example, opening, closing, tilt) as it corresponds to the engagement of the elastic protrusions 29 in the recesses 28.

[0066] The mounting kit for a manual control device of a window or door lock, as conceived, is subject to numerous modifications and variations, all falling within the scope of the inventive concept; furthermore, all details can be replaced with technically equivalent elements. In practice, the materials used, as well as the dimensions, can be any, depending on the needs and the state of the art.
