Description

[0001] The present invention relates to the technical field of curtain head mechanisms, in particular a steel band stabilization system without a pull cord.

[0002] The steel band mechanism for roller shutters is typically mounted on the shutter and primarily serves to exert an upward pulling force on the shutter fabric to counteract its own weight. The more the shutter fabric is pulled down, the greater the deformation of the steel band, thus balancing the weight and allowing the shutter fabric to be held in any desired position after being pulled.

[0003] In conventional steel band mechanisms for roller shutters, the steel band is arranged as follows: The steel band, which tends to unwind, is wound in a ring shape, with the outer end of the band attached to the mechanism's housing and the inner end attached to a self-rotating pivot. When the roller shutter is operated, the pivot rotates, winding the steel band inwards. However, this type of arrangement has the following disadvantages: Since the steel roller is manufactured from a naturally flat steel strip by winding, the steel strip itself has a tendency to unwind and thus exerts an initial tensile force on the roller shutter fabric. Therefore, it is essential to provide a counterweight on the roller shutter fabric to compensate for this initial tensile force. Without a counterweight, however, the initial resistance of the roller shutter to operation becomes excessively high. This also causes the roller shutter to be pulled upwards a short distance after being pulled, meaning the desired hold-in position after pulling cannot be achieved. Furthermore, with this type of steel band mechanism, the center of the steel roller becomes increasingly taut as the roller shutter fabric is pulled down. This results in an uneven tensile force from the steel band.Particularly when applied to double-layered roller shutters, this means that the inner and outer fabric layers cannot be precisely aligned with the light-tight layer, which means that complete light protection cannot be achieved.

[0004] The object of the present invention is to provide a cable-free steel band stabilization system that enables curtains to be raised with minimal effort, ensures a uniform distribution of force during operation, and prevents recoil once the pulling motion ceases.

[0005] The steel band stabilization system without a pull cord according to the present invention serves to control the contraction or expansion of curtain fabrics, comprising: a housing that can rotate itself to wind up curtain fabric, a gear unit inside the housing and a steel band; wherein the gear unit comprises a fixed shaft, a planetary shaft, a winding shaft, and an unwinding shaft; wherein the fixed shaft is a stationary component and is arranged coaxially with the housing; wherein the planetary shaft meshes externally with the fixed shaft and is connected to the housing as a single unit, so that it is driven by the housing to orbit the fixed shaft; wherein the planetary shaft is rotatably connected to the housing to maintain its own rotation during the orbital motion; wherein the winding shaft is connected to the planetary shaft and can thereby be driven to rotate; and wherein the unwinding shaft is arranged on the same side as the winding shaft and runs parallel to the winding shaft, the unwinding shaft being rotatably connected to the housing; and wherein the steel strip is arranged in the form of a roll on the outside of the unwinding axis, and the outer end of the roll of the steel strip is connected to the winding axis to form a unit.

[0007] As a further improvement of the present invention, an end section of one side of the fixed axis is provided as a gear section with a gear, and the other end section is provided as a limiting section with a larger diameter than that of the gear section, wherein the gear section is arranged in the gear housing and the limiting section in the mounting base; wherein a stepped surface between the gear section and the limiting section rests against an end face of the inner lining; wherein a bearing is arranged on the outer circumference of the limiting section, the outer ring of which is recessed into the inner wall of the housing, so that the housing can rotate independently relative to the fixed axis;wherein the outer circumference of the limiting section and the inner wall of the housing both have projecting limiting steps, wherein the inner ring and the outer ring of the bearing each abut the limiting steps of the fixed shaft and the housing to achieve axial limitation.

[0008] As a further improvement of the present invention, the facing end faces of the gear housing and the steel strip roller housing are positively connected to each other by a convex-concave fit, and the facing end faces of the cover and the steel strip roller housing are also positively connected to each other by a convex-concave fit, wherein at least one gear housing, at least one cover and at least one steel strip roller housing are clamped together by passing screws through them; wherein the gear housing and the mounting base are also clamped together by passing screws through them.

[0009] As a further improvement of the present invention, two limiting lugs are symmetrically provided on the two opposing outer circumferential surfaces of the gear housing, and mounting lugs are symmetrically provided on the two opposing outer circumferential surfaces of the steel strip roller housing, the mounting lugs extending axially towards the gear housing; wherein the facing end faces of the gear housing and the steel strip roller housing are positively positioned by means of a convex-concave fit, and the mounting lugs are snap-fit ​​connected to the limiting lugs, so that the steel strip roller housing and the gear housing are firmly coupled to each other; wherein two limiting lugs are also symmetrically provided on the outer circumferential surfaces of the two sides of the cover, which are suitable for snap-fit ​​connection with the mounting lugs.

[0010] As a further improvement of the present invention, a groove is also provided on the side surface of the gear housing into which the mounting lugs can be inserted in order to achieve a positive locking positioning.

[0011] As a further improvement of the present invention, an arbitrary number of covers and steel band roller housings are provided, which are arranged in groups in the axial direction towards the gear housing, wherein each group is constructed in the sequence first steel band roller housing, then cover, and several such groups are provided; wherein the cover of a front group is detachably connected to the steel band roller housing of a rear group.

[0012] As a further improvement of the present invention, a through mounting bore is provided in the center of the mounting base for mounting the fixed shaft; a fixed shaft bore and a planetary shaft bore are provided on the end face of the gear housing facing away from the mounting base; a first inner lining bore and a second inner lining bore are each provided on the end face of one side of the inner lining facing the mounting base; an unwinding shaft bore and a winding shaft bore are provided on the end face of the steel strip roller housing facing the gear housing; a first cover bore and a second cover bore are provided in the cover. wherein the first inner lining bore is arranged coaxially with the fixed axis bore and the mounting bore, wherein the second inner lining bore is arranged coaxially with the planetary axis bore, the winding axis bore and the second cover bore, and wherein the first cover bore is arranged coaxially with the unwinding axis bore; wherein the fixed axis successively penetrates the mounting bore, the first inner lining bore and the fixed axis bore; and wherein the planetary axis with its two end sections is received in the second inner lining bore and the planetary axis bore and has a rotational capability; wherein both the winding axis and the unwinding axis are axially secured in the steel strip space by axial limiting steps, wherein a rotationally fixed bore is provided on one side of the winding axis, and the planetary axis has a rotationally fixed cutting surface on the outside of the end section facing it, so that the winding axis is rotationally fixed and axially limited on one end section of the planetary axis and is simultaneously inserted through the winding axis bore; wherein the other end of the winding axis is supported in the second cover bore and also has a rotationally fixed cutting surface that interacts with the rotationally fixed bore, so that the planetary axis drives the winding axis to simultaneously rotate around the fixed axis and rotate around its own axis;wherein the unwinding axis is arranged at a distance from the winding axis, wherein the two ends of the unwinding axis are each inserted into the unwinding axis bore and the first cover bore, so that it has a rotational capability;

[0013] As a further improvement of the present invention, the steel strip in its natural state has a wound-up form, wherein the steel strip automatically winds itself into a sleeve and is slipped over the outer circumference of the unwinding axis.

[0014] As a further improvement of the present invention, a limiting block is fixedly arranged on the outer circumference of the winding axis, and a limiting recess is provided at the outer free end of the steel strip, wherein the limiting recess and the limiting block are snap-fit ​​together to connect the steel strip and the unwinding axis.

[0015] Compared to the prior art, this invention has the following advantageous effects: 1) In contrast to the conventional arrangement, where the wound steel strip has an outer diameter close to that of the housing, the winding shaft in the present invention has an outer diameter that is significantly smaller than that of the housing. With a simultaneous rotation of the housing, the required length of the steel strip is therefore shorter, thus reducing the material consumption of the steel strip.

[0016] 2) The steel band is already coiled in its natural state. Therefore, the gear unit can cause it to unwind and extend or to wind and retract. The user does not have to overcome any initial pulling force from the steel band when operating the curtain, resulting in low operating force and smooth operation. As the steel band unwinds, the applied pulling force remains constant throughout all phases, preventing an increase in the required pulling force as the band is pulled, thus improving ease of use. Because the pulling force generated by the steel band changes uniformly, there is no upward springback of the curtain due to excessive pulling force after the curtain is pulled.

[0017] Design I: As in Fig. As shown in Figures 1 to 10, this invention provides a cable-free steel band stabilization system for controlling the contraction or expansion of curtain fabrics, comprising a housing 1, a gear unit 2 and a steel band 3; wherein the gear unit 2 is mounted in the interior of the housing 1 and the steel band 3 is wound or unwound by the gear unit 2.

[0018] The housing 1 comprises a gear housing 11, a steel band roller housing 12, a mounting base 13, a cover 14, and an inner lining 16. The cover 14, the steel band roller housing 12, the gear housing 11, and the mounting base 13 are connected end-to-end in this order, forming an interior space for the transmission unit 2.

[0019] A continuous mounting hole 131 is provided in the center of the mounting base 13.

[0020] The gear housing 11 rests against the mounting base 13 at its end face and is screwed to it by the screw 15. A fixed shaft bore 112 and a planetary shaft bore 113 are provided on the end face of the gear housing 11 facing away from the mounting base 13. A groove is provided on the side of the gear housing 11 facing the mounting base 13, with the inner lining 16 being fixedly arranged in the groove and, together with the inner wall of the gear housing 11, defining the internal space of the gear unit. The end face of the inner lining 16 facing the mounting base 13 rests against and is connected to the mounting base 13.On the end face of one side of the inner lining 16, which faces the mounting base 13, a first inner lining bore 161 and a second inner lining bore 162 are each provided, wherein the first inner lining bore 161 is arranged coaxially with the fixed axis bore 112 and the mounting bore 131, and the second inner lining bore 162 is arranged coaxially with the planetary axis bore 113.

[0021] Two limit lugs 111 are arranged on the two symmetrical outer circumferential sides of the gear housing 11. Two mounting lugs 121 are arranged on the two symmetrical outer circumferential sides of the steel strip roller housing 12, the mounting lugs 121 extending axially towards the gear housing 11. The end faces between the gear housing 11 and the steel strip roller housing 12 are positioned by a positive-locking connection consisting of protrusions and recesses. Additionally, grooves are formed on the side surface of the gear housing 11 into which the mounting lugs 121 are inserted to achieve further positive-locking positioning. The mounting lugs 121 engage positively in the limit lugs 111, thereby establishing a secure connection between the steel strip roller housing 12 and the gear housing 11.

[0022] On the end face of the steel strip roller housing 12, which faces the gear housing 11, an unwinding axis bore 122 and a winding axis bore 123 are provided, wherein the winding axis bore 123 is arranged coaxially with the planetary axis bore 113 and the second inner lining bore 162.

[0023] The end faces between the cover 14 and the steel strip roller housing 12 are positioned by a positive-locking connection consisting of raised and recessed areas, with the cover 14, the steel strip roller housing 12, and the gear housing 11 being screwed together by means of the screw 15. A steel strip interior is defined between the cover 14 and the inner wall of the steel strip roller housing 12. The upper and lower sides of the steel strip interior are designed as openings. Two limiting lugs 111 are also arranged on the two symmetrical outer circumferential sides of the cover 14.In the cover 14, a first cover bore and a second cover bore are each formed, wherein the first cover bore is arranged coaxially with the unwinding axis bore 122 and the second cover bore is arranged coaxially with the winding axis bore 123; in addition, the first cover bore is symmetrical to the second cover bore relative to the axis center line, and the unwinding axis bore 122 is symmetrical to the winding axis bore 123 relative to the axis center line.

[0024] The gear unit 2 comprises a fixed axis 21, a planetary axis 22, a winding axis 23 and an unwinding axis 24.

[0025] The fixed shaft 21 successively passes through the mounting bore 131, the first inner lining bore 161, and the fixed shaft bore 112. At one end of the fixed shaft 21, a gear section with a fixed gear 211 is formed, and at the other end, a stop section with a larger diameter than the gear section is formed. The gear section is located inside the gearbox, and the stop section is arranged in the mounting bore 131. The stepped surface between the gear section and the stop section rests against the end face of the inner lining 16. A bearing 25 is arranged on the outer circumference of the stop section, with the outer ring of the bearing 25 being recessed in the inner wall of the mounting bore 131, allowing the housing 1 to rotate relative to the fixed shaft 21.Both on the outer circumference of the limiting section and on the inner wall of the housing 1, limiting steps are formed, with the inner and outer rings of the bearing 25 bearing against the end faces of the limiting steps of the fixed shaft 21 and the housing 1, respectively, to axially fix the bearing 25. A cross groove is provided at the rear end of the fixed shaft 21, which serves for connection to an externally arranged stationary holder, so that the fixed shaft 21 is designed as a stationary component. In other feasible embodiments, the outer circumferential surface of the fixed shaft 21 rests directly against the inner wall of the mounting bore 131.

[0026] The planetary shaft 22 is located inside the gearbox and is positioned outside the fixed shaft 21. Both ends of the planetary shaft 22 engage in the second inner lining bore 162 and the planetary shaft bore 113, respectively, and are capable of rotation. A planetary gear 221 is fixedly mounted outside the planetary shaft 22, meshing with the fixed gear 211. This causes the planetary gear 221 to be driven by the rotation of the housing 1, so that it simultaneously rotates around the fixed gear 211 and can rotate on its own axis.

[0027] Both the winding shaft 23 and the unwinding shaft 24 are arranged within the steel strip interior under axially stepped constraints. A rotationally fixed bore is provided at one end of the winding shaft 23, and a rotationally fixed surface is provided on the outer surface of the planetary shaft 22 at the end facing the winding shaft 23. The winding shaft 23 is mounted on one end of the planetary shaft 22 in a rotationally fixed and positionally fixed manner and simultaneously engages in the winding shaft bore 123. The other end of the winding shaft 23 is supported in the second cover bore and has a rotationally fixed cutting surface corresponding to the rotationally fixed bore, so that the planetary shaft 22 drives the winding shaft 23, which simultaneously rotates around the fixed axis 21 and rotates on its own axis.The unwinding axis 24 and the winding axis 23 are arranged at a distance from each other, with both ends of the unwinding axis 24 engaging in the unwinding axis bore 122 and the first cover bore, respectively, to allow rotation. It should be noted that the end of the unwinding axis 24 located in the first cover bore does not completely fill the first cover bore, but only occupies half of it.

[0028] The steel strip 3 is already coiled in its natural state and is not flat. The steel strip 3 coils itself into a sleeve and is wound onto the outer circumference of the unwinding shaft 24. A limiting block 231 is fixedly arranged on the outer circumference of the winding shaft 23, and a limiting recess 31 is provided at the free end of the steel strip 3, which is located on the outside. The limiting recess 31 and the limiting block 231 interlock to connect the steel strip 3 and the unwinding shaft 24. After the steel strip 3 is installed, it is visible through the openings in the interior of the steel strip. Working principle:

[0029] During installation, the aforementioned rope-free steel band stabilization system is inserted into the curtain sleeve, with the outer side of the sleeve being connected to the curtain fabric and allowing the sleeve to rotate to wind or unwind the curtain fabric. The fixed axis 21 is rigidly connected to the wall via an externally arranged bracket.

[0030] When the curtain fabric is pulled down or moved up, the sleeve rotates and drives the housing 1, with the fixed axis 21 remaining stationary. This drives the planetary axis 22 through the housing 1 to rotate around the fixed axis 21. The planetary axis 22 also rotates due to the comb connection between the two. The rotation of the planetary axis 22 further drives the rotation of the winding axis 23. The direction of rotation of the planetary axis 22 determines whether the steel band 3 is wound up or unwound. When the curtain fabric is pulled down and the planetary axis 22 rotates clockwise, the winding axis 23 rotates and unwinds the steel band 3, causing it to rewind onto the winding axis 23.Since the steel band 3 has a tendency to roll up, the tensile force of the steel band 3 increases with increasing roll-up length on the winding axis 23, thereby pulling the lowered curtain fabric more effectively and preventing the curtain fabric from falling down due to its own weight.

[0031] Since the steel band 3 is coiled in its natural state, the spring force generated by the steel band 3 increases uniformly during the lowering of the curtain fabric and does not rise excessively, thus preventing the curtain fabric from being moved upwards on its own due to excessive tensile force of the steel band 3 and from no longer being able to be positioned arbitrarily.

[0032] Furthermore, the steel strip 3 is continuously wound onto the winding shaft 23, the outer diameter of which is significantly smaller than that of the sleeve and the housing 1. Consequently, the length of the steel strip 3 required for a curtain fabric of the same length is considerably shorter. For example, the housing 1 must complete 30 revolutions to fully lower the curtain fabric, which also requires 30 revolutions of the winding shaft 23. However, due to the smaller outer diameter of the winding shaft 23, the length of the steel strip 3 is significantly shorter for the same 30 revolutions.

[0033] Furthermore, the number of steel bands 3 can be increased if the length of the curtain fabric is excessively long. Specifically, for this purpose, a steel band roller housing 12, a steel band 3, a winding shaft 23, an unwinding shaft 24, and another cover 14 are retrofitted axially towards the center of the curtain fabric on the end face of the cover 14. The retrofitted winding shaft 23 and the original winding shaft 23 are fitted together to form a rotationally fixed unit, with one end of the retrofitted unwinding shaft 24 located in the first cover bore of the original cover 14 and the other end positioned in the first cover bore of the retrofitted cover 14. The retrofitted steel band roller housing 12 can also be snapped to the cover 14 to form a unit via the mounting lugs 121 and the limiting lugs 111.
