Description

Technical Field

[0001] This industrial invention patent application relates to an innovative design handle for a tilting and rotating window frame. Background Technology

[0002] After a brief introduction to the relevant prior art and its most relevant disadvantages, the features and advantages of the present invention will become apparent.

[0003] As is well known, most rotating windows (leaves) use a lever-based opening and closing system. These levers slide alternately along the pillars of the window sash and are controlled by rotating a handle to operate the corresponding mechanical device.

[0004] In addition to alternating between the closed and open positions, it is sometimes conceivable that, according to the logic of the so-called "tilting rotating window sash," the window sash of the window frame can also be arranged in a third partially open position, wherein the window frame tilts inward toward the interior of the corresponding compartment.

[0005] Currently, the most commonly used window frame handles, which provide the aforementioned versatility for the corresponding window sashes, are often referred to as "cremone handles".

[0006] In a typical Cremon handle, the handle component can be positioned in three different locations relative to the window sash pillar, depending on the usage conditions of the window sash.

[0007] Specifically, it is stipulated that the handle component of the Cremone handle is in a horizontal position—that is, perpendicular to the pillar axis of the corresponding window sash—so that the window sash is pulled to its open position.

[0008] In addition, it is stipulated that the handle component must be in the first vertical position, rotated downward by about 90° relative to the open state of the window sash, so that the window sash is in the closed state.

[0009] Finally, it is stipulated that the same handle component must be set in the second vertical position, rotating upwards by about 90° relative to the opening of the window sash, so as to be able to tilt and rotate to open the window sash.

[0010] In this case, it can be envisioned that the handle component of the Cremone handle engages with a plate (or, in industry terms, a “casing”) fixed to the window sash post, thereby operating the appropriate mechanism located within the casing.

[0011] More specifically, the handle component causes the gear to rotate in the opposite direction, which engages with a corresponding rack mounted coaxially on the window sash pillar, both of which are located within the housing.

[0012] On the side opposite to the gear, the rack supports a laterally arranged portion that drives a sliding rod located within the window sash pillar, thereby alternately opening, closing, and tilting the window sash.

[0013] Therefore, it can be envisioned that as the handle component of the window handle rotates relative to its central position (corresponding to the opening of the window sash), the rack can alternately move upward to bring the sliding rod of the window sash to the closed position, and move downward to bring the window sash to the tilted open position.

[0014] While this window frame opening and closing mechanism based on the use of Cremonese handles is highly efficient and reliable, its drawback is that it requires a fairly large housing—which is generally considered aesthetically unappealing—precisely because it must be able to accommodate the rack and pinion assembly while also allowing the rack to move vertically in the opposite direction. Summary of the Invention

[0015] It was this critical observation of the aforementioned technologies that led to the conception of this new invention, the main purpose of which is to provide a handle for a window frame equipped with a mechanism for opening and closing the window sash of the window frame. This mechanism is completely innovative and, most importantly, extremely compact, ultimately enabling a reduction in the housing size of the new handle according to the invention.

[0016] Another object of the present invention is to make the novel handle extremely versatile, so that it can be easily installed on right-rotating and left-rotating window sashes, and always ensure that the window sash of the corresponding window frame can also be in the typical partially open position of the tilting rotating window sash.

[0017] The above-mentioned objectives of the present invention have been achieved in accordance with the features listed in the appended independent claim 1.

[0018] Advantageous embodiments of the invention can be seen from the dependent claims. Attached Figure Description

[0027] - Figure 5 Similar to the previous attached image, but showing the handle from the inside. Detailed Implementation

[0028] Referring to the above figures, the handle M according to the present invention generally includes an operating handle component 1 and a housing 2, which is fixed to the outside of one of the pillars of the window sash of the corresponding window frame.

[0029] The handle component 1 includes a grip 1a and a spherical body 1b, the spherical body 1b being arranged at a 90° angle to the grip 1a; wherein, the center of the spherical body 1b is provided with an axial hole 1b' of a square cross section.

[0030] The housing 2 has an arcuate profile and includes two generally semi-circular side surfaces 2a that surround a circular central surface 2b. A cylindrical protrusion 20 is provided at the center of the central surface 2b, and the cylindrical protrusion 20 is passed through the center by a circular hole 20a and is in a protruding position.

[0031] The handle component 1 is adapted to apply reverse rotation to the bevel gear 3 protruding from the square pin 30, which is connected to the gear 3 via a cylindrical shoulder 31.

[0032] During use, the gear 3 is installed inside the housing 2, and its shoulder 31 is rotatably engaged in the central hole 20 of the housing 2, while the square pin 30 protrudes from the outside of the housing 2, thereby connecting with the axial square hole 1b' prism of the spherical body 1b of the handle component 1.

[0033] The gear 3 is adapted to operate the lever 4, which is described in detail below.

[0034] The lever 4 includes:

[0035] -The central part 4a is basically composed of side-mounted plates;

[0036] - The rounded tip 4b is higher than the center part 4a;

[0037] -Protruding side arm 4c, which is perpendicular to plate 4a;

[0038] - Component 41, which is laterally supported by the arm 4c, wherein the component 41 is generally configured as the arc of a bevel gear;

[0039] - A transverse hole 40, which passes through the plate 4 and the side arm 4c, is used to receive a cylindrical pin 5, wherein the ends 5a and 5b of the pin 5 protrude slightly on both sides of the hole 40.

[0040] In this case, the component 41 of the lever 4 is arranged such that its conical tooth profile 41a meshes with the gear 3.

[0041] It should be noted that the function of lever 4 is to operate a conventional mechanical device to ensure the opening, closing and tilting of the corresponding window frame, in the same way as the conventional Cremon handle, that is, through the upper and lower racks operated by corresponding gears.

[0042] It should also be considered that, during use, the lever 4 is adapted to be partially fixed in the housing 2, at which time the ends 5a, 5b of the pivot pin 5 are permanently embedded in a pair of opposing horizontal grooves 2a' that are generally C-shaped and formed on the inner side of the leading edge of the side surface 2a of the housing 2, at approximately half the height of the housing 2.

[0043] Next, we will continue the explanation by describing the operation of the new handle M.

[0044] As shown in the figure, handle M can be alternately set to three different positions: open, closed, and tilted, as shown below. Figure 1 / Figure 1A , Figure 2 / Figure 2A and Figure 3 / Figure 3A As shown.

[0045] By observing these figures, it can be seen that the prerequisite for the handle M to transition from one operating condition to another is that the handle component 1 of the window handle M can rotate 180° in the opposite direction, thereby accurately transmitting the force to the gear 3, and then from the gear 3 to the lever 4.

[0046] Figure 1 and Figure 1A The handle M is shown in the open state of the window frame. At this time, the handle is in a horizontal position and perpendicular to the corresponding post L of the window frame IN.

[0047] In this case, the lever 4 provided in the handle M remains in a horizontal position and is substantially aligned with the square pin 30 of the gear 3.

[0048] Specifically, this horizontal position of lever 4 does not activate the conventional mechanism provided in the window sash pillar of the window frame, which is used to close or tilt the window frame.

[0049] Figure 2 and Figure 2A The image shows the window frame handle M in the closed position. At this time, handle component 1 rotates downward by approximately 90°, while lever 4 also tilts downward.

[0050] Preferably, the lever 4 rotates downward at an angle of approximately 45°.

[0051] The second position of lever 4 means that the traditional mechanism set in the pillar of the window sash of the corresponding window frame is adjusted to a position that can close the window frame.

[0052] Figure 3 and Figure 3A The image shows the handle M in the tilted position of the corresponding window frame. At this time, the handle component 1 rotates upward by about 90°, which causes the lever 4 to tilt upward as well.

[0053] In this case, the lever 4 is preferably rotated upwards at an angle of about 45°.

[0054] The third position of lever 4 means that the traditional mechanism set in the pillar of the window sash of the corresponding window frame is adjusted to a position that allows the window frame to be tilted open.

[0055] Now, please pay attention. Figure 4 and Figure 5 This allows for a better understanding of the main advantages of the invention in reducing the height of the housing 2 located in the new handle M discussed.

[0056] In fact, the above figures show that the height of housing 2 can be limited to allow lever 4 to alternately be in position. Figure 1 The downward tilt position shown and Figure 3 The space required for the upward tilt position shown.

[0057] In order to fully describe the new handle M under discussion, it must be pointed out that the front edge of the cylindrical protrusion 20 of the housing 2 is provided with four hemispherical recesses 21, arranged at 90° intervals, which are suitable for precise connection with the corresponding cylindrical holes 11 provided at the front of the spherical body 1b of the handle M.

[0058] The groove 21 provided in the housing 2 is adapted to selectively accommodate (two at a time) a pair of balls 22 spaced 180° apart, while the cylindrical hole 11 provided in the spherical body 1b is adapted to accommodate two helical springs 23, which are adapted to permanently push the balls 22 toward the direction of the hemispherical groove 21.

[0059] The function of these balls 22 (when they fall into a pair of grooves 21 and are thus located between the housing 2 and the handle component 1) is to determine and stabilize the position of the handle component 1 in the open, closed and tilted positions, respectively.
