Description of the invention (1) Description of the invention The invention relates to a device for adjusting the relative angular position of two structures that are connected to each other at a joint, and is particularly suitable for adjusting parts of a chair or a seat cushion, such as It is used to adjust the height of the seat cushion of the office swivel chair or to adjust the backrest of the car seat cushion that is tilted back. Similar applications can be considered with reference to, for example, the adjustment of the inclination of the seat cushion of an office chair, the adjustment of an armrest, or other types of adjustment of a moving part of a chair. However, although the following description makes particular reference to the preferred embodiment in the field of adjusting chair height, it is important to note that the present invention can be widely applied to any field-in which it is necessary to provide locking of two parts connected to each other at joints. Possibility of arbitrary relative angular position. In specific areas of adjusting the position of the moving parts of a chair, for example, adjusting the height and / or inclination of a seat cushion, or the position of a backrest or armrest, various devices have been known that have been used for some time. The height adjustment of the office seat cushion is usually achieved by a cylinder having a gas assisted spring or the like. Various mechanisms are also used to adjust the position of various parts of the chair, such as the backrest or armrest. The problem faced by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs in printing the present invention is to develop a device that, as already mentioned, is suitable for a wide range of uses, but is still particularly suitable for the field of chairs, seat cushions or the like, making Ability to lock any adjustable component in any position along its stroke with an extremely simple, effective and low cost solution. In order to solve this problem, the purpose of the present invention is to adjust the size of two papers to apply the Chinese National Standard (CNS) A4 specification (210X297 mm) 537876 A7 B7 V. Description of the invention (2) The pieces are connected with each other at a joint Device for the relative angular position of a structure, characterized in that it comprises:-a first and a second element connected to the structure individually, which rotate about each other around the joint axis of the structure, and define two chambers between them The volume of the chamber changes inversely due to the relative rotation of the element; a conduit element for connecting the volume-variable chamber together, the conduit element and the chamber being filled with fluid such that, due to the first and second As a result of the relative rotation of the elements about their joint axes, the fluid passes from one chamber to the other via the catheter element, and a valve element is used to interrupt the communication via the catheter to prevent fluid from passing from one chamber to another Chamber, so the two elements are locked in any relative position for adjustment. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Preferably, the valve element includes a normally closed valve and a valve opening control device, which can be operated to allow adjustment of the relative angular position of the element. The control device may consist of, for example, a button or lever with a flexible return mechanism, which is held in the active position by the user in order to be able to manually turn one element relative to another around their joint axis, Until he reaches the required position adjustment, the control device can then be released to interrupt the communication between the two-volume variable chambers, and the structure is locked in the new position it has reached. Preferably, the device is provided with a flexible implement adapted to return the elements to their original end position of the reciprocating stroke. In this way, when the device is released, it is adjusted in one direction with the help of the above-mentioned flexible machine, and in the other direction -4- This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 537876 A7 ___B7_ 5 2. Description of the invention (3) The adjustment of the flexible implement is reversed. As described above, the device made according to the present invention is suitable for a wide range of uses, but is still particularly suitable for the field of chairs, seat cushions or the like. One form of a preferred embodiment relates to a chair, particularly an office chair, including a seat cushion with adjustable height, which is characterized in that the chair includes a bottom structure and a cushion, and the cushion is connected to the end by a joint arm Structure, two ends of the joint arm are joined to the seat cushion and the bottom structure on a parallel horizontal axis, and an adjustment device made according to the present invention is co-linear with at least one of the axes of the joint. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs According to yet another preferred feature, the joint arm forms a part of a parallelogram connection between the above-mentioned base structure and the seat cushion. Therefore, the seat cushion of the chair can be moved vertically because it is connected to the bottom structure by the parallelogram connecting member described above. The parallelogram connector includes two parallel joint arms, one of which is provided with a device made in accordance with the present invention at one of its joint ends. When the device is locked, the entire system is fixed, so the seat cushion of the chair is maintained at a certain height. Releasing the device allows the quadrilateral connector to be oriented. As a result, it is possible to adjust the height of the seatpost. Once the seat cushion is connected again by the two volume-variable chambers of the device installed at one end of the joint arm After the interruption has reached the required height, the height of the seat cushion can be locked again. In a different embodiment, the two ends of a single joint arm are equipped with devices made according to the present invention. In this embodiment, the first variable volume chamber of the device at one end of the joint arm is connected to the paper at the other end of the joint arm. The paper size is applicable to China National Standard (CNS) A4 (210X297 mm) 537876 A7 B7 5. Description of the invention (4) The first variable volume chamber provided at the second end of the joint arm is connected to the second chamber at the first end of the joint arm by the aforementioned valve. . So, in this embodiment, the locking of the system is achieved by interrupting the communication between the two individual chambers at the opposite ends of the joint arm. However, in the above two embodiments, a single valve can control the entire system of the adjustable seat cushion support of the chair to be locked to the bottom structure. Notwithstanding this, this does not preclude the possibility of providing a separate adjustment device that is collinear with the different joints of the structure connecting the cushion to the base. In addition, it is clear that a device made in accordance with the present invention can also be applied to the adjustment of other parts of a chair, such as the forward or backward tilt of a seat cushion, the tilt of a backrest, or the position of an armrest. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. It is also obvious that the device made according to the present invention can also be simply and quickly applied to the adjustment of a car's tilted back or any other adjustable component of a car seat cushion. In this application, a device made according to the present invention provides the benefit of being able to be continuously adjusted on the one hand, and having a very simple, reliable, and low-cost construction on the other. The back adjustment devices for automobile seat cushions that can be continuously adjusted are relatively complicated and costly, and also involve a long adjustment time. On the other hand, simpler adjustment devices currently available for adjusting the back of a car seat cushion have the disadvantage that the back can only be positioned in a series of predetermined positions, thus allowing stepwise adjustment. However, as mentioned several times, a device made according to the present invention can be successfully used in any application, where a very simple, reliable and low-cost solution is needed to provide continuous adjustment of two pieces to each other to The size of the paper is applicable to the Chinese National Standard (CNS) A4 specification (210X mm) A7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 537876 B7 V.

Description of the invention (6). In fact, this application makes it possible to obtain the optimal position of the seat cushion at a variable height. Note that the settings of the backrest and the armrest shown in Figure 1 can be adjusted in response to independent adjustments. However, the movement can be adjusted in synchronization with the position adjustment of the seat cushion. In Fig. 1, reference numeral 8 shows the bottom structure of a chair, which in the illustrated example is made in a well-known design, including a central pillar provided at the bottom, and the spokes are mounted on casters. Reference number 9 designates the seat cushion of the chair, which is connected to the bottom structure 8 by a joint arm 30, and the end of the joint arm 30 is joined to the seat cushion 9 and the base structure by the adjusting device 4 made according to the present invention. 8. Similar devices are provided at the joints between the backrest 10 and the seat cushion 9 and between the armrest 11 and the backrest 10. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the operation principle of the device 4 made according to the present invention is schematically shown in Figures 2, 3 and 4. The figure shows a section, which is the axis of the joint of the device. Two components connected to each other at joints (for example, the base structure 8 and the arm 30 connecting the base structure 8 to the seat cushion 9) are individually connected to a cylindrical body 4, which contains a fixed sector 5 and a mobile sector 6 The moving sector 6 is guided so that it rotates inside the cylindrical body 4. Between the opposite sides of the fixed sector 5 and the mobile sector 6, there are two chambers 1 and 2, whose volume changes inversely with the relative rotation of the two joint parts. The chambers, individually designated by reference numbers 1 and 2, are arranged to communicate with each other by cutting through the passage of the fixed sector 5 and by a flexible external conduit 3. The conduit and chambers 1 and 2 are filled with any kind of fluid, such as oil. The fluid tightness of each chamber 1 and 2 is ensured by a deformable diaphragm 1 a and 2 a, which is sealed to a fixed sector 5 and this paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 537876 A7 B7 V. Description of the invention (7) Move sector 6. Fig. 2 shows a moving sector 6 which is located at an intermediate position between its two extreme positions. In this case, the two chambers 1 and 2 have substantially the same volume. In the conduit 3 there is a valve 7 provided with a shutter, on which a spring (not shown) is supported, which tends to keep the shutter in the closed position. In this situation, the communication between the two chambers 1 and 2 is interrupted, so the joint is locked, and the two joint parts cannot rotate with each other. By acting on the valve 7 to open the connection via the conduit 3, the relative angular position of the two joint parts can be continuously adjusted. Figures 2 and 3 show the two extreme positions of the adjustment range. At each position, one of the two chambers 1 and 2 reaches its minimum volume and the other chamber reaches its maximum volume. Correspondingly, the diaphragms 1 a and 2 a extend or compress between the opposing surfaces of the sectors 5 and 6. In the case of the illustrated example, the movement of sector 6 is guided by a pin / slot coupling 10, 1 1 from Figures 2-4. Obviously, the fixed body 4 and the fixed sector .5 form the first An element defining a cavity having a circular sector concentric with the joint axis of the device. The second element of the joint, element 6, thus constitutes a piston that has no parts (eg, sealing elements) in sliding contact with the cavity wall as it moves in the cavity, however, because the fluid tightness in chambers 1 and 2 is It is ensured by the diaphragms la and 2a that when the diaphragm is pressed by the moving sector, each diaphragm is folded down to wrap itself around the corresponding end of the sector 6 (see Figures 3 and 4). Theoretically, a device 4 of the kind shown in Figure 2 can be provided for each joint of the chair shown in Figure 1.

Description of the Invention (8) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs '' printed on a single valve, it can make two or more adjustment devices Move in sync. For example, Fig. 5 shows a first embodiment of this solution, which is applied to the two joints at the end of the oscillating arm 30, which joints connect the support structure 8 of the chair to the seat cushion 9. In this case, the second adjusting device 4 basically has the same structure as that described with reference to Figs. 2 to 4. However, the two-volume variable chambers of each adjustment device 4 are not in direct communication with each other. Actually, the chamber 1 of the adjustment device 4 installed at the bottom end of the arm 30 is connected to the related adjustment device 104 of the related device 10 by the duct 31 at the top end of the arm 30, and the second variable volume chamber 102 of the adjustment device 4 is A conduit 33 is connected to the second chamber 2 of the related adjusting device 4 at the bottom end of the oscillating arm 30, and the valve 7 is inserted into the inside of the conduit 33. In Figure 5, the valve is schematically shown as including a conical shutter 34 with a spring 35, which returns it to the position to be closed via the connection of the conduit 33; the shutter can be manually opened by a button 36 It has the opposite effect to that of the spring 35, causing it to move to a position, and the connection via the conduit 33 is opened. When the connection is opened, the oscillating arm 30 can rotate, so that the height of the seat cushion 9 can be adjusted, and the connection existing through the conduits 31 and 33 ensures that the joints of the arms 30 bis move synchronously. During the height adjustment, It is guaranteed that the seat cushion 9 is maintained in a position parallel to its original state. Reference numeral 37 indicates a spring, which is placed between the base structure 8 and the body of the adjusting device 4 to return the arm 30 to its raised position. As shown in the figure, the body of the adjusting device 4 is fixed to the joint arm 30, and the sector 6 of the adjusting device 4 is connected to the bottom structure 8. At the same time, the arm 30 is fixed to the fixed sector 105 of the adjusting device 104, and the moving sector of the adjusting device 104 is fixed-10- This paper size applies to the Chinese National Standard (CNS) A4 specification (210X297 mm) 537876 A7 B7 5 Description of the invention (9) Connected to the seat cushion 9. Reference numbers la, 2a, 101a, and 102a individually designate diaphragms associated with the variable volume chambers of the two adjustment devices 4 and 104. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. Figures 6-10 show a preferred embodiment of a system for connecting a seat cushion of a chair to a corresponding support structure using the device according to the present invention. The 6th and 7th solids show the system at the two extreme positions, which corresponds to the minimum height and the maximum height of the seat cushion that can be adjusted. In this case, the seat cushion 9 of the chair is connected to the bottom structure 8 by a hinged parallelogram system. In the case of the illustrated example, the base structure 8 includes a fork-shaped bracket 80, which includes two independent parallel plates 81 mounted on the bottom by pins 8a. The pins 8a are supported in a way that can be supported by an unillustrated support structure (any (Known type) to rotate around its axis (so that the chair can rotate about a vertical axis). The two plates 81 support joint pins 82 and 83 (FIG. 10) having axes 82a and 83a to allow the joints to connect an upper arm 84 and a lower arm 85, and the cross-sectional shape is substantially similar to two letters facing each other "C ". The opposite ends of the two arms 84 and the arm 85 are articulatedly connected by an upper pin 86 on the axis 8 6 a and two lower pins 87 (defining an axis 91) on the support member 8 9 bis independent parallel plate 88. The supporting member 89 is a C-shaped cross section (FIG. 9), and the seat cushion 9 is joined to each other. There is a body between the two plates 8 8 of the support member 8 9, which is made of aluminum, for example, and is indicated by the reference number 90. It rotates freely with respect to the upper pin 86 and rises from the lower arm 8 5 with the pin 8 7. The axis 91 is collinear and defines an adjustment device made according to the present invention. In fact, as shown in Figures 6 and 7, the front end of the lower arm 8 5 includes two walls 8 5 a and 8 5 b, which are arranged in the g direction of the joint axis 9 1, and the walls 85 a and 85 b face the support 9. Corresponds to a flat surface, which is also -11-This paper size applies to Chinese National Standard (CNS) A4 (210X297 mm) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 537876 A7 __B7__ V. Description of the invention (1〇) On axis 91 Radial to define the two volume-variable chambers 1 and 2 of the device. Each of the chambers is associated with a corresponding deformable diaphragm la and 1 b, and they are also connected to each other by a passage 93 through an aluminum body 90. The aluminum body 90 can be intercepted by a ball valve 94 and the ball valve 94 by a spring 95 It remains in the closed position and is turned on by a person working for the control button 96. From the previous description, it is clear that in this embodiment, the seat cushion of the chair is connected to the bottom structure by a parallelogram connection, and the adjustment device made according to the present invention is only collinear with an axis of the joint of the parallelogram connection . In fact, when the adjustment device aligned with the axis 91 is locked, any relative rotation between the aluminum body 90 and the lower arm 85 aligned with the joint axis 91 is prevented, and as a result, any movement of the entire parallelogram connection structure is prevented. . Reference number 37 designates a spring, which tends to push the back of the seat cushion upward, and is placed between a body 37a. The body 37a is articulated at 37b to one of the flanges 37c of the lower arm 85, and the other end of the spring is joined to A connecting rod 110 rests on the support element 8. When the button 96 is operated to make the communication between the two-volume variable chambers 1 and 2 effective, the spring 37 is tilted upward to rotate the parallelogram connecting the joints. Therefore, in this situation, the user can move the seat cushion upwards only by the return force of the spring 37, or he can move the seat cushion by applying his own weight to the seat cushion in opposition to the force of the spring 37 down. Therefore, in the above embodiment, a single adjustment device that is collinear with the joint axis of the parallelogram connector can be used to lock the entire parallelogram connector in any given condition between its two extreme positions. -12- This paper size applies to Chinese National Standard (CNS) A4 (210X 297 mm) (Please read the precautions on the back before filling this page)

Description of the Invention (11) In addition, the communication between the two-volume variable chambers is achieved through the passages inside the body 90, so no form of outer tube or catheter is needed. Obviously, this type of adjustment system can be used in any field-where it is necessary to provide the possibility of locking a joint-connected parallelogram in any given position. Furthermore, it is obvious that the present invention can also be applied to a single joint axis between two components in principle, as shown in the configuration shown in Figs. 2 to 4. Naturally, the shape and configuration of the valve that controls the communication between the variable volume chamber and the related operating mechanism may be in any form. For example, referring to Figures 6 and 7, it is obvious that the valve 94 must be designed to prevent any communication between the two-volume variable chambers, even when a considerable force from a parallelogram system that tends to move joints is applied from the outside Of course. As already mentioned above, the invention is particularly suitable for the field of automotive seat cushions to adjust, for example, the tilt of the backrest.
