The invention relates to the faucet with a timer mechanism, which automatically closes the flow of water from the tap.

THE BACKGROUND TO THE INVENTION

Currently, it is essential to water conservation. Many cities and States have passed laws related to water conservation. Some decisions relate to the automatic closing water taps installed in public toilets.

Previously known devices timers have the complex mechanisms that increased the cost of the tap. The extra expense arose due to the presence of one spring mechanism to close the valve of the faucet and a separate second spring mechanism for actuating the escapement mechanism, which determines the time of closing of the valve.

Were developed dopey and people with physical disabilities, fully accessible public toilets. One of these standards provides for easy opening of the valve. For ease of use, the crane should have a handle of this form so that it can be easy to adjust and rotate. Moreover, the force required to rotate the handle in the open or operating position, should not be more than 2.25 kg, to ensure that most users can easily open the faucet to gain access to the water.

However, for many cranes action required to open the valve differs from the actions required to close the valve, i.e., the movement to open can be a great and easier than going to close. For example, if the handles have a view of the plates, the force of the opening can be formed by pressing, which is much easier than pulling back plate for closing the faucet.

Self-closing faucet, however, eliminates the need for translation of the valve handle to the closed position manually. The most common way is to create a self-closing faucet, comprising a timer mechanism, spring-loaded, which moves the handle to the closed position.

In the previously known cases, to simplify the mechanism that is in effect without the necessity so wore out prematurely. Secondly, previously known valves could be stuck in the working position or the full thread, if there was a malfunction in the mechanism of gears and seized.

Thus, you need a reliable automatic faucet, which is easily operated and provides automatic closure of the water and the additional possibility of closing manually.

The prior art.

A DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the embodiment shown in Fig. 1 and 2, a self-closing faucet 10 includes a housing 12 of the crane with a tip 14, a handle 16 hot water and the handle 18 of cold water, set on the valve body. Handles 16 and 18 hot and cold water and appropriate internal valves and mechanisms timetolive at the same time, what side of the cold water has the same design or its mirror image.

As shown in Fig. 2, the rotatable element of the valve 20 is normally mounted in the chamber 22 of the valve housing 12 for rotation between a closed and an open position for flow of fluid from inlet 24 to outlet 26 or closing it. The chamber 22 of the valve is normally closed at its upper end 28, as shown in Fig. 2 and 3, locking and closing element 30. Closing element 30 has held up section 31. The valve element 20 is attached without turning to the control spindle 32, which passes through the locking closing element 30 of the valve are also usual. Lock nut 34 holds the locking and closing element 30 and the valve seat. Conventional seals 36, 37 and 38 hermetically seal the chamber of the valve and prevent leakage of the crane.

The handle 16 also includes a section 40 of the plate and the section 42 housing. Section 42 of the housing, as best shown in Fig. 2, is hollow and has an upper portion 43 and aimed down the side wall 45 forming the cavity 44, an open bottom, and planted outside on node 46 of the housing of the timer and closes it. Node 46 of the housing of the timer, as shown in Fig. 2 and 3, has a lower ucantry ledges 50, as shown in Fig. 5 to ensure proper angular location of the node 46 of the housing on the housing 12. The lower portion 48 has two slots 52 through which passes the connecting spring clip 54, which is engaged with the outer peripheral groove 56 in the retaining nut 34 and is held in axial direction by means of the upper flange 58 above the groove 56.

In Fig. 2 and 4 is shown a spiral spring 60, which is located in the hole 62 on the upper section 64 of the housing 46 of the timer. The outer end 66 of the coil spring 60 is attached to the upper part 64 of the inside peripheral slits 68 of the housing 46, while the inner end 67 of the spring 60 is fixed in the slit 69 of the shaft 70.

The lower end 72 of the shaft 70 is attached without turning to the control spindle 32. One of the common ways to install the shaft without turning is that the control spindle 32 has a D-shaped cross-section and the lower end of the shaft has an additional receiving D-shaped aperture 74.

The casing 76 of the trigger is located on the upper section 64 of the housing 46 and around the shaft 70. The casing 76 of the trigger contains a plot of the cylindrical wall 78 and a portion of the upper cover 80. Top the e pass up from the wall 78 and engages with the slots 83 in the top cover. The upper pins 82 are radially outward to provide the location of the casing 76 in alignment with the opening 62 of the housing 46. In the casing 76 and the top cover 80 is provided by the relevant arranged in a line the holes 86 and 88 for placement with the possibility of rotation of the Central section 85 of the shaft 70, so that the upper portion 87 of the shaft 70 passes through the casing of the trigger 76 and above.

As best shown in Fig. 2 and 6, the inside of the casing 76 is the trigger mechanism 77 timer, which contains the intermediate gear 90 mounted to rotate in the casing of the escapement mechanism. Gear 90 passes through an opening 91 in the side wall of the casing 76, so that the intermediate gear 90 is engaged with the toothed wheel 92. Gear 92 is made as one piece with the upper section 64 of the housing 46 around the Central hole 62 in which is placed a casing 76.

A number of leading gears and toothed wheels 94 is installed can be rotated sequentially, i.e. in the form of a gear transmission, inside the housing 76 in the form of an arch around the Central hole 86. On the other end of the gear has rappelling gear 96 with the respective beveled teeth 98. The teeth 98 engages with the rotation of the gears, when the intermediate gear moving around the periphery of the toothed wheel 92 under the action of the torque forces generated in the casing of the escapement mechanism, as described hereinafter. The movement in the axial direction down the casing of the trigger 76 on the shaft 70 is prevented by the lug 101 on the shaft 70, which has a larger diameter than the hole 86 at the bottom of the casing 76 to prevent the influence of the coil spring 60.

In Fig. 2, 4 and 7 shows the ratchet 102, which is located on the top cover 80 of the housing 76 of the trigger. As best shown in Fig. 4, the ratchet has a Central opening in the form of a polygon 104, which engages without turning from serving additional part 106 around the hole 88 in the cover 80. Thus preventing rotation of the ratchet 102 regardless of the casing 76 of the trigger mechanism; i.e., the ratchet 102 and the housing 46 rotate together. Over the ratchet 102 is a node 110 clutch. The ratchet is directed upwards, tilted at an oblique angle, spring peripheral teeth 108 on the ends of the resilient spring fingers 109, which are directed upward, ensuring engagement with the hub 110 of the friction clutch, as described in more detail later.

Winnow nut 118. The disk 112 with the teeth of the ratchet has an upper surface 120 and lower surface 122 with teeth. The bottom surface 122 with teeth has many grooves 124 that have been designed to accommodate the peripheral teeth of the ratchet 108 on the ends of fingers 109. The slope of the engagement of the teeth 108 with grooves 124 is made such that it allows, as shown in Fig. 4, to rotate the ratchet 102 counterclockwise relative to the disk 112 with the ratchet teeth, because the teeth 108 are tilted down and out of the grooves 124, but prevent rotation of the ratchet 102 clockwise relative to the disk 112 with the teeth of the ratchet.

The upper surface 120 has a flat radial outer peripheral section 126 of ring shape and a flat radial inner section 128, which is lower than the area 126. A circular hole 130 is made in the center of the disk 112 to accommodate with the ability to rotate the upper portion 87 of the shaft 70. An inclined intermediate section 132 connects the sections 126 and 128.

The friction disk 114 is a flexible Teflon layer of material with a Central hole 134 is performed so that the area of the shaft 87 passed through him. Spring disc 116 has a Central opening 136, , the.E. he always rotates together with the shaft 70. Push nut 118 is pressed down on the area of the shaft 87 in order to load the spring disc 116 by pressing on the Central section 138 around the hole 136 located below the outer edge 140, causing it creates a force directed along the axis on the disk 112 with the teeth of the ratchet. Teflon layer 114 regulates the sliding or twisting force on the shaft 70, is necessary in order to create a slide spring disc 116 with respect to the disk 112 with the teeth of the ratchet,

To prepare the crane for shipment pin 142 is inserted into a side opening 144, as shown in section in Fig. 2 and 5, it comes in a radial direction into the cavity 146 in the lower section 48 of the body below the flange 148 to prevent falling out in the axial direction of the housing 46 of the shaft 70 and held in the casing 76 of the trigger, ratchet 102 and node 110 friction clutches.

In Fig. 2 and 3 shows the node housing 46, which includes a rotating part of the cover 150 having a Central mounting hole 152 and which is planted without turning to the area of the shaft 87 to rotate together with it. The periphery of 154 details of the cover 150 includes two extending downward flange 156, which is the second opening. The speed of rotation from fully closed to fully open can be reduced by adding two removable inserts 164, which may join the stopper 162 to open. Insert 164 can be set via the cylindrical pins 166 inserted into the hole 168 in the cover 150.

The handle 16 has a section 42 housing, placed outside of the housing 46 of the timer, and its position is precisely defined by setting two passing down pins 167, placed in holes 171 in the cover 150. Bolt 169 passes through the Central hole 170 in the housing 42 and through the Central hole 172 in the shaft 70. Bolt 169 is screwed into the threaded hole 174 in the spindle 32 to fasten the entire Assembly of the handle.

In operation, the crane click on the plate to rotate clockwise the knob. When this movement opens the hot valve. The clockwise rotation of the handle 16 also provides the twisting of the spring 60. The clockwise rotation of the shaft 70 also provides the rotation of the spring disc 116 and the friction Teflon layer 14 is provided by the rotation of the disk 112 with the teeth of the ratchet. However, the ratchet 102 is not rotated, because the teeth 108 are released from the grooves 124. Therefore, mahaa of the valve handle 16.

Upon release of the handle 16 after it has been rotated, the force of the twisted torsion spring 60 moves the shaft counter-clockwise direction to the closed position. When the shaft is rotated, the spring disk is rotated together with him and also by the friction rotates the disk 112 with the teeth of the ratchet counterclockwise. The disk with the teeth of ratchet connected with the ratchet 102 during counterclockwise rotation by engagement with the teeth 108. The ratchet through the hole 104 actuates the entire casing of the escapement mechanism and causes the trigger mechanism 77 in action. Intermediate gear 90 which engages with the toothed wheel 92, slowly turn the shaft counterclockwise to the closed rotation through known steps of gears 94, release gear 96 and friction clutch 100 in the release mechanism 77.

The interval between the time when the flange is adjacent to the stopper 162 full open and the time when it is adjacent to the stopper 160 to close approximately fifteen seconds. Installation of inserts 164 reduces the time due to the shorter stroke to approximately ten seconds. Other intervals can be easily kidston additional lengthening or shortening of the arc of rotation of the handle 16.

Usually the trigger mechanism, driven by the force of the spring 60, provides movement of the valve handle 16, the shaft 70, and thus, the element 20 of the valve from a fully operating or open position to a fully outside or closed position when the slow descent through the trigger mechanism.

However, if desired, to close the valve faster, you can simply press on the plate 40 to rotate the handle counterclockwise direction. Torque force directed counter-clockwise created on the handle and, hence, on the shaft, will cause the node 110 of the slip clutch will slip disk 116, moving relative to the disk 112, thus unwinding the spring 60 and moving the handle, the shaft and the valve in closed position without the influence of the whole trigger mechanism. Node 110 of the slip clutch also provides backup, it allows you to manually close the valve of the faucet when jammed the trigger mechanism 77 or broken spring 60, while the valve of the faucet is in the working position.

The friction force generated by the node 110 friction clutches, more than the torque force required to release the ratchet teeth 108 of discala, when the handle is moved to its working position. The friction force generated by the node 110 of the friction clutch, is also greater than the torque force to the closure created by the spring 60, which allow the trigger mechanism 77 to act through node 110 of the friction clutch and close the handle 16 without slipping, while at the same time providing the opportunity slip under the action of additional torque forces created manually on the handle in order to quickly close the valve.

All these functions are combined in the valve, which uses a rotary movement to close and open the valve. The entire Assembly housing 46 of the timer with its elements placed in the handle of the valve plate, which is moved between the closed and open position normal intuitive way.

The single-acting positive-displacement servomotor is made so that, under the action of pressure, the pressure chamber provides the action of its output link on the output link of the flexible member directed oppositely to the direction of flexible force of the flexible member and movement of the output link in the position in which it does not act on the driving link of the closure member and driving link can freely move under the external control action between the closure position and open position of the closure member. Under the action of pressure in the pressure chamber, the output link of the flexible member is held in the mentioned above position. When there is no pressure, the output link of the positive-displacement servomotor together with the driving link returns under the action of the flexible member to the closure position of the closure member.
