Description of the invention () The invention refers to a door arch with the excellent features described in item 1 of the scope of patent application. By way of example, such a door bow is known from DE 9319541 U1, which was originally created by the applicant. The door arch announced in the case revealed a 5-resistance spring and a hydraulic cushioning element. The resistance spring directly acts on the buffer piston and works with it in a common housing. This door arch is provided with a pinion gear that meshes with the internal tooth train of the buffer piston. There are actually two problems with this structure. On the one hand, because the buffer piston surrounds the mandrel of the door archer, the thickness of the door arch toward the radial direction of the mandrel of the door archer is quite large. On the other hand, the resistance spring is provided in a part of the buffer device and is in contact with the hydraulic oil. If the cushioning device is defective or leaking, the part of the door arch related to the resistance spring must therefore also be opened. The high repair costs caused by this procedure are usually similar to those in which the door archer must be replaced entirely. 15 The door arch described in the patent DE 198 20 382 A1 discloses an energy storage tank in the form of a resistance spring, but it is separated from the door arch spindle by a drive. In addition, this door arch is not provided with a cushioning device. Patent No. DE 195 482 02 A1 shows a friction damper 20 that can be used with this type of door archer, but it must be provided separately on the guide rail of the door archer assembly. However, this type of friction damper cannot achieve the intended closing process as can be obtained using a hydraulic damping element. TECHNICAL DISCLOSURE Therefore, an object of the present invention is to create a door archer capable of having a streamlined structure. In addition, the present invention also seeks to create a simple way that this paper size applies to the Chinese National Standard (CNS) A4 specification (210X 297 mm) (Please read the precautions on the back before filling this page)

Description of the invention () Door arches that separate the transmission assembly and the buffer assembly from each other. These tasks can be solved using a door archer having the features described in item 1 of the scope of the patent application. Since the resistance spring and the door bow mandrel are not in contact with the hydraulic oil of the buffer device, the dynamic pressure 5 occurring during the operation of the buffer device will not affect them. Therefore, the 'resistance spring and the door bow mandrel can be arranged relatively simply, especially in the thin-walled casing section which does not need to prevent the leakage of hydraulic oil. Because this' has the advantage of saving material and labor costs during manufacturing. In addition, 'the wall thickness of the energy storage tank part of the cabinet is very thin, which reduces the overall size and weight of the door archer. If the energy storage tank' door archer mandrel and buffer device are combined into a common structure Within the unit, the housing section can be adapted to their individual needs in accordance with the design of these components and their wall surfaces. However, they can also be installed on a door or a frame like a conventional door archer. The resistance spring can be operated with 15 kinds of actuators, especially with a chain on the door bow mandrel. This provides a simple, economical, and reliable power transmission. Depending on the installation situation, the 'buffer device' may be better positioned radially beside the bower mandrel or axially on the door bower mandrel. Similarly, the door archer shaft is sometimes preferred to be located between the resistance spring and the cushioning device. On the other side, the buffer device and energy storage tank may be more suitable for the door of the door arch mandrel. Then, set the door arch mandrel as far away as possible from the end of Ji Yi. In addition, the cushioning device should preferably include a cushioning piston driven by a rod, such as a set of connecting rods. In this case, it is possible to arrange the effective directions of the M% 1 and the resistance springs in parallel ', especially coaxial.

Description of the invention () C Please read the notes on the back before filling in this Page] The force (momentum) exerted by the mandrel can effectively balance it. If the door arch mandrel can be rotated about an axis substantially perpendicular to the door arch, the door arch can have a satisfactory movement and a flat structure, especially in the axial direction. 5 It is particularly advantageous if the cushioning device is arranged with a separate housing section so as to be able to rotate in the resulting direction. Depending on the installation, the buffers with adjustment valves can be oriented to adjust these valves from the accessible side of the door frame or panel. The casing section of the buffer device which is circled toward the door arch mandrel may carry a circular collar facing outward for snapping into the open groove of the shaft 10 and form a joint with it Swivel support. The resistance spring preferably belongs to a helical spring that is externally enclosed in a sleeve, so that the end of the sleeve facing the door arch mandrel can form an internal connector for the balance seat / end stop as a resistance spring . In addition, the initial torque (prestressing force) of the resistance spring can be adjusted by using an adjusting device that can be used for the end of the sleeve facing away from the door arch mandrel. In this way, a simple and operationally reliable adjustment design is provided. If at least part of the actuator is adjacent to the sheath surface of the door arch mandrel cover, and thus the surface of the sheath exhibits a kind of printing from the consumer property cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs from the door arch mandrel, Decreasing interval based on the angle, as a result, the effective lever or balance arm engaging the transmission 20 at the door arch mandrel can almost be selectively adjusted. Therefore, the effective transmission of the 'transmission' should be in the range of low door opening angle, which is the largest at the door arch spindle. A particularly effective way to achieve this is that the actuator uses a lever to engage the door bow mandrel in the range of low door opening angles in order to achieve a slightly cosine torque, and when the door opening angle is large, the drive- 5- This paper size applies the Chinese National Standard (CNS) A4 specification (X297 mm), and the door bow mandrel is roared so that the momentum (inertia) from that point will not decrease substantially. If the effective ha of the actuator at the door bow mandrel is within the range of moderate door opening angle, then when opening the door, a good and comfortable lever is provided in the range of medium door opening angle. In addition, this can effectively increase the door opening angle. When this happens, if the door is opened, it will increase the opening force. Although this situation does not limit the door opening angle kinematically, it can prevent the door from hitting obstacles with strange force. In doing so, the thickness and / or form of the actuator, especially those related to different length links of a transmission chain, can be used to easily determine changes in the lever or balance arm. There are many variations, all of which are available at low cost. The present invention will be described in detail hereinafter with the examples and the drawings. The first figure is a top sectional view of a door archer according to the present invention. 15 The second figure is a side sectional view of the door archer as shown in the first figure. The third figure is an enlarged view of the cushioning device of the door arch as shown in the first figure. The fourth figure is another view of the buffer device taken along line IV_IV in the third figure. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Detailed description of the preferred embodiment. 20 The sectional view of the door arch is shown in the first figure. The door bow mandrel can rotate in a casing (2), so as shown in the first figure, the axis of rotation is at the level shown in the figure. The door arch mandrel (1) divides the cabinet into a cabinet-only section and a short cabinet section at a ratio of about 2/3: 1/3. The long case section is equipped with -6980 paper sizes that are applicable to the Chinese National Standard (CNS) A4 specifications (21 × 297 male thin). 5.

A transmission chain (6), which acts as a transmission, connects the transmission rod (5) with the door arch spindle (1). In addition, the transmission chain (6) is engaged with a bearing (7) at a distance from the center axis of the door arch mandrel. 5 The proximal end of the resistance spring (3), which is closer to the mandrel, is protected at the bottom of the sheath (4), and the remote end, which is farther away than the pump, is located in a connection with the transmission rod (5) and can be stretched On the spring seat (9). The sheath (4) is also connected to an adjustment screw (11) by a cover (10) and is stretchable. The adjustment screw (11) is again supported against the remote end of the casing (2) from the front. 10 The short casing section is equipped with a cushioning device provided with a cylindrical casing section (12) in which a cushioning piston (13) is inserted. The buffer piston (13) is connected with a piston rod as a whole, and the piston is connected with a connecting element (15), which is connected with the door bow mandrel (1). The action point of the connecting element (15) on the door arch mandrel (1) is close to the action point (7), so that there will be a ha between the 15 connecting element (15) and the door arch mandrel (1). . The buffering device further includes a conventional adjusting screw (16) for fixing a valve ball (18) on its base by a pressure spring (17). In this way, a pressure-limiting valve is created, which limits the resulting internal pressure when the door is opened and closed quickly. In addition, the piston (13) is equipped with a 20 recoil valve (20) that can open the door without buffering, but when the door is closed, the recoil valve is closed. Finally, the piston (13) is provided with a ring (21) to separate the two operating spaces of the hydraulic oil.

It can be clearly seen from the figure that 'the chain (6) in the actuator of the force spring has two chains' which are respectively connected to the upper and lower parts of the door arch of the second figure, and the connecting element (15) is Is a 'joint' between the two keys ⑹ of the door arch mandrel. What is not shown in the second figure is an enlarged sectional view of the buffer device of the first to the second figures. It can be seen from the figure that the casing section of the turning (M) channel part is provided with a collar (23) facing outward The collar essentially surrounds the shaft U4) in a rotationally symmetrical manner. A sliding sleeve (2 sentences) is provided between the shaft (14) and the casing section (12) to control the guide of the shaft (14). The tf in the fourth diagram is along the buffer device of the third diagram. The cross-section view taken along the line ιν · ιν. It can be clearly seen that there are two adjustable blocking valves laterally near the guide of the shaft (14). These blocking valves help adjust the buffering degree so that One controls the entire opening range of the door, while the second valve acts on the angular range just before the door is closed, thereby reducing the cushioning of this angular range so that the door can be quickly engaged in the door frame. In fact, to The operation method of the present door archer is as follows: a lever handle installed on the door or a shear link group accompanying the door, as shown in the first picture, will move counterclockwise when the door is opened, The door arch mandrel (丨) rotates counterclockwise. The door arch mandrel (1) uses pressure from the actuator (8), the transmission rod (5) and the spring seat (9) to press the balance bearing. Block (8). In this way, the energy required to close the door is stored. The buffer element is connected via the connection shown in the first figure The piece (15) and the shaft (15) are pressed to the left, so that the hydraulic oil can pass through the recoil valve (20) without accumulating a considerable buffer resistance.

Invention description (Each operation room flows into another operation room. When the door is opened against the resistance of the resistance spring (3) alone, a speed-dependent inertia will be caused and substantially generated. Another example is the first and second figures As shown, when returning to the rest position, the resistance spring (3) expands against the spring plate (9), and passes through the transmission rod (5) at the action point (7) of the door arch spindle (1). Pull with the actuator (6). This will cause a kind of anti-clockwise torque as shown in the first figure, so that the door connected to the door arch will be closed. In this process, because the piston (13) must not Let the hydraulic oil pass through the recoil valve (20), but it must flow from the regulating blocking valve (25) into the left operating chamber. As a result, a closing action buffer is caused, thereby limiting the closing rate. 10 At the last moment of the closing process, when the door arch spindle (1) has substantially reached the position shown in the first figure, the action point ( 7) Ha is particularly large with the axis of rotation of the door arch mandrel (1). On the other hand, the second blocking valve (25) is actuated in parallel with the first blocking valve to reduce cushioning. This The two effects will increase the closing inertia and the door closing rate, so the resistance of the door frame which may generate impedance is safely overcome. One advantage of the door bow is that the collar is engaged in the long casing section. So that the entire casing section (12) can rotate around the central axis defined by the axis of the shaft (14). In this way, the blocking valve (25) can be rotated in either direction. Regardless of the installation position of the door archer, the casing section (12) of the machine 20 can be rotated to access the blocking valve (25). In addition, an advantage of the present invention is that the size of the casing, that is, the width shown in the first figure, is substantially only composed of the lever / balance arm between the door arch spindle (1) and the action point (7). To decide. As a result, the door archer belongs to a relatively narrow structure, and can be easily installed in the door plate without protruding.

Description of the invention (Come out. Another basic advantage of the configuration shown is the modular structure, that is, the door archer of the present invention is characterized by an energy storage tank on one side of the door arch mandrel and the other side A buffer element is provided. If the leakage of the buffer element occurs, it can be removed from the actual door arch for repair or replacement without the need to disassemble the rest of the door arch. Finally, in the energy storage tank The part 'such as the resistance spring (3) does not need special precautions to prevent the hydraulic pressure / freedom from escaping' because this part of the door archer does not have hydraulic oil. This makes the structure simpler and easier to adjust The initial tension of the resistance spring (3). Adjusting the 10 screws (丨 〇) can actually use a threaded section (26) (as shown in the second figure) to pull the entire sheath (4) and the bottom plate (8) away. Door arch mandrel (1). Therefore, the initial stress of the resistance spring (3) is increased, so that the door has a larger closing inertia at a smaller opening angle. In summary, the present invention provides an installation size that is extremely small Door archer, 15 pairs with door archer mandrel In terms of wire, it can be reduced to about 40 mm. Therefore, this door arch is suitable for installation in the door panel. In addition, this door arch is characterized by a relatively simple mechanical structure in which the two functional groups are separated from each other 'only The buffer zone requires no leakage of hydraulic oil. This modular structure is particularly easy to repair. Finally, this door archer can be used in more than 20 installation positions without modification. The energy storage tank is pressureless and does not affect hydraulic oil. The leak-proof casing can be kept very thin, so even if it is in a relatively small size, it can also be filled with a very strong resistance spring. In this regard, if compared with a conventional door arch with the same installation thickness, Can achieve a large inertia. The case can be easily manufactured -10- This paper size applies the Chinese national standard (cys) A4 size (210 X 297 mm) (Please read the note r on the back before filling this page) Order -Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, printed 568980 A7 B7 5. Description of the invention () Molded parts are made, so it is very economical. The advantages of the modular structure for the manufacturing process are various A universal cushioning element can be used for each position, so if the door arch is changed to have other rotation ranges, only the energy storage tank and actuator need to be replaced, and the same cushioning element can still be used in these other models. 5 pieces The energy storage tank must be a compartment that does not leak hydraulic oil. An inspection hole or indicator pin can be used to directly perform optical control on the position of the spring prestress. Until now, pick-up of the initial stress is still an item. Mechanically demanding problems are solved, for example, by magnetically moving the position of the bearing outwards. 10 In this regard, simple visual inspections are not only very cost-effective, but also practically desirable. Because the initial adjustment of the door arch for a certain size door is an important item of the fire door. If the identification of the spring pretension is not satisfactory, it will lead to incorrect basic adjustment, which will result in safety consequences.
