Abstract

There were state of the art sprinklers in the prior art relatively difficult to install and set them up to be guaranteed not to shower on people who are used the rooms in question. We made a device (1) that with the help of a precisely adjustable release lever (6) moves the rocker arm (10) to the wheel (61) counterintuitive. The rocking lever (10) pushes the release lever support (8) with her nose (8a) from her standstill; angle support (2), which is below spring tension (7), with its hammer part (2a) strikes the encoder (50) provided with a normal spray pump so that it is designed spray. Working spray room readiness of the device (1) is based on the rotation of the lever (60) in the clock I. Release versions of the release lever (60) facilitate installation of the room surface treatment plant so that almost in all installation cases are delayed spray, so that persons in the room are not affected.

Description

Room sprayer

The present invention relates to a room spray device with a release mechanism, wherein a tray is provided in the room spray device having a container for or with odor-neutralizing and / or odor-neutralizing fluid and which is sprayed, the container neck containing a valve a pump and nozzle body, the impact lever being provided, which is spring-supported in the direction of the valve body by means of at least one spring, and the impact lever is provided with a stop and damper device.

The invention further relates to the preferred use of the object of the invention.

EP 0 127 573 BI describes a room sprayer according to the introductory part of claim 1. As it turns out, the device in question conditioned a special position in the room or door to prevent the shower from falling on people. Adjustment options are relatively limited, because the transmitter opens via a linearly shifted release lever, with a similarly movable locking lever provided for closing. Due to the kinematic circumstances of the arrangement, it is also necessary to account for the relatively high forces that necessitate the proper careful installation of the room sprayer, especially on the door.

Therefore, one of the object of the invention is to create a device of such dimensions that the device will not affect the movement of the door, which does not condition or condition only a minimum number of such damage-causing fasteners and which can be arranged so as to prevent to keep the resulting shower from falling on people - e.g. when using toilets or washrooms.

According to the invention, the aim is to provide a pivoting stem to which a pivotably mounted pivot lever that raises and closes the impact lever in an outwardly swiveled position, moves the lever to a secured position in the intermediate position, and releases the lever for spray purposes in its rest position. .

Bearing the swinging stem, i.e. the relaxation performed on the circular segment, and the corresponding closure of the mechanism, ensures precise steering movements and requires only small forces that can withstand rolling friction.

An important advantage of the indoor sprayer according to claim 1 is the simple installation of the latter, which, due to its large attachment surface, requires only a minimal number of mechanical means.

The following dependent claims describe further useful features of the object of the invention.

The swing arm of claim 2 is functionally advanced and subject to only minor wear.

The support-like impact lever of claim 3 can be easily restrained and released.

The damper / release support of claim 4 is kinematically advantageous in that it is arranged on the impact lever.

The mounting of the supporting roller according to claim 5 on the basis of linear contact with the damper / release support ensures precision damming with minimal torque requirement.

The damper / release support under the load of the return spring according to claim 6 offers the advantage of defined functional stages.

The return support defined in claim 7 is advantageously used to restore the ground state of the functions without the need for any special auxiliary energy.

The polygonal cross section stem according to claim 8 is, in the most basic case, a square cross section stem, which ensures the transmission of non-slip torques.

The release stem with the release wheel at its end proved to be reliable - according to claim 9, because in this way the fastening means act on it only with minimal friction forces and in this connection only with low shear forces.

The release lever design according to claim 10 facilitates the very simple and precise adjustment of the desired control functions of the device.

The two-piece release lever according to claim 11 is advantageous in terms of design and allows it to be manufactured in a cost-effective manner.

It is often practical to install a release lever inside the door opening to make the embodiment of claim 12 useful.

A manually operated (as a knee) release lever, which is the content of claim 13, facilitates bridging larger release distances, while still maintaining preset mounting locations for the device.

The result of the use according to claim 14 is the extremely simple activation of the room sprayer.

The following claim 15 describes a particularly useful use.

Hereinafter, a detailed description of the preferred embodiments of the subject matter of the invention will be made with reference to the drawings.

In the sketch of FIG. 1 is a schematic representation of a room sprayer marked with reference number 1. The device is in working condition, as can be seen by label III, which indicates the working state of PRHA.

Sketch of FIG. 1 shows an impact lever 2 designed as a rocking rocker arm (support). This impact lever has a front, hammer part 2a, and at the rear there are bearing tongues 2b, which are in one piece (integral) with two levers 2c, each with its own nose 2d. The bearing tongues 2b include a stem 3, which with its ends is integrated into a (not shown) housing.

The lower stem 4, which is accessed from below, serves as a mounting point for the bearing tongue 8b of the damper / release support 8. The latter at its end is provided with a backward facing ridge element 8a.

The ridge element 8a, with its recess 8c, rests on a support cylinder 11, which is designed as a sleeve, which is rotatably mounted on a stationary stem 5.

Two screw springs 7 are clamped between the stems 4 and 5, which store the kinetic energy to activate the sprayer pump of the commercially available sprayer 50 (CWSAG, Switzerland).

An upright spaced rocking stem 6 with a rectangular cross section is inserted through the back central portion 10b of a three-legged rocker arm 10. On an incoming surface 10aa with its noses 1a, it has a spring loaded with its noses 9a (spring not shown) with a return support 9. 60 ends the upper end of the stem 6 square section, swivels in an hourly direction, the rocking lever 10 is rotated sideways. As a result, the front relaxing nose lOc of the rocking lever 10 touches the ridge element 8a and moves it away from the vertical, thereby - cf. FIG. 2 - causes the latter to fall on the support cylinder 11 with its notch 8c. At the same time, the rocking lever 10 tilts the spring-loaded impact lever 2 around its stem 3 to an oblique position.

From the sketch of FIG. 1 is by way of the sketch of FIG. 2 it can be easily seen that the ridge element 8a protrudes into the rocking path of the relaxing nose lOc, which can therefore tilt the part 8 from its upright position, FIG. 2.

Functional state II presented in FIG. 2, corresponds to the working condition INSURED. Room sprayer 1 is prepared for Condition III, illustrated in FIG. 1.

If the release lever 60 - FIG. 1 - With its release wheel 61, which rotates about the hinge 62, pivots in the direction of the dashed arrow (counter-rotation), the operating state is CLOSED.

Through rock 6, the rocking lever 10 then rotates outward toward the observer; one of the ridge-engaging surfaces 10aa is glassed with the left nose 2d of one of the lever arms 2c and, while simultaneously tensioning the spring 7, raises the impact lever 2 with its hammer portion 2a to the upper end position. At the same time, the damper / release support 8 is pulled onto the support roller 11 by means of a (not shown) spring 28 and, if necessary, lowered onto that roller 11, with the latter being touched in a linear fashion. In this way, functional state II is established, FIG. 2.

The characteristic positions of the rocking lever lOa-lOc in its possible out-of-position positions I can be seen in FIG. 3, which shows that, depending on the setting of the release lever 60 with its release wheel 61, the lever 60 leads to the left or - if desired - right activation of the device so that the rocking lever 10 acts on the left or right nose 2d of the impact lever 2 (see Fig. 1).

The positions described above correspond to the thick lines drawn in FIG. 3; the equally possible positions correspond to the line-dotted line of the rocking arm 10 or its ridge-picking surface 10a.

It is further seen that in these two end positions / in each case the opposite nose is the one that cooperates with the part of the return support 9.

Comparison of the sketches of FIG. 3 and FIG. 4 shows that the rocking lever 10 disposed in its central position restores the PRHA operating state presented in FIG. 1.

Further movement of the lever 60 in the direction indicated in FIG. 4 (counter-rotational direction), returns the impact lever 2, FIG. 2, to its horizontal position, where it again occupies position II, i.e. position INSURED.

Sketches fig. 3 and 4 further show the walls 12 of the device together with the horizontal bearing sleeves 13 arranged therein for the stems 3, 5 and 18 (Fig. 5). Also, in FIG. 3 and 4 show a cutout 12 'for receiving the neck of a spray liquid container.

Further details regarding the internal structure of the object of the invention, as well as variants of the release lever, which is indispensable for operation, can be seen in the following sheets:

Also, the partial cross-section shown in FIG. 5, illustrates the functional components already discussed. In addition, it is apparent that for the hammer portion 2a of the impact lever 2, an interchangeable impact piece 53 is arranged which is adapted to affect the conventional spray pump of the device 50 according to the hammer striking method. We further see that a return spring 28 is arranged, suspended at one end by a stem 24 ', which is mounted in the bore 24, and by a hole 29 on the other. Similarly, during the mounting rod 17, the return support 9 and a similar pole 18 mounted in opposite bearing sleeves 13 (Figs. 3, 4) in the walls 12 of the apparatus, spaced spring 19.

An upright rocking stem of 6 square cross section is mounted in the bearing sleeves 14 and made rotatably by means of bearing rings 14 '. These bearing rings, which are known as such, have an inner hole of square cross section corresponding to the stem 6, and are cylindrical on the outside and are slidably adapted to the sleeves 14.

The wall 12 of the device is completely obscured by the normal cover 12a, so that all the components of the device are protected.

The mounting cutouts 15 are expediently provided in wall 12, so that, if necessary, the device can be screwed and fastened at the installation site. In addition, a locking mechanism 16 is provided which can be known in a known manner by means of a special key.

Of particular note is the internal design of the two-piece release lever 60. From the section representation in the upper part of the sketch of FIG. 5 shows all the essential details: the release wheel 61 and its hinge 62, which consists of a hinge insert 63 and a screw 64. The rocking stem 6 has a fixed spaced wheel 66, which engages a snail 67, which has screw ends 68 on both ends. The release lever 60 has an upper lever housing and a lower housing which are fixed to one another by at least one screw 65.

Sketch of FIG. 6, which according to FIG. 5 is rotated, revealing further details from the drawings of FIG. 1-4; above all, two springs 7 are visible here, which are suspended by their ends by the stems 4 and 5. The design of the walls 12 and the cover 12 'are also evident.

Figs. 7a-7c show impact lever 2 in all its details. In the hammer portion 2a, centers of bore 21 are provided for receiving the impact portion 53. The bore 21 is crossed by a hole 22 for installing the pin for securing the impact piece 53. Also bore holes 23 for receiving the stem 4, bore 24 for the stem 24 'for hanging the return spring 28 and bore 25 for stem 3 in bearing tongues 2b.

The cutout 20 seen in FIG. 7a, serves for access and suspension of spring 7 on stem 4 - see also the sketches of FIG. 1 and 6.

The angle impact lever 2 (see figures 7b and 7c) is rigidly reinforced with ribs 27 and can therefore be mechanically loaded.

Swing lever 10 - sketches FIG. 8a-8c, which is presented in three different views, is of a three-pronged design, see FIG. 8c. Through this component there is a hole lOf a square section, which fits into the stem 6. Two ridge-picking surfaces lOa with noses lOd are provided. The central part of the lOb has a reinforcing rib lOe that ends with the relaxing nose lOc.

Also, curb / release support 8 - sketches FIG. 9a-9c - has a reinforcing rib 8e in which a hole 8f is provided for the spring 28 (see FIG. 5). In the upper part of the support 8 there is a bearing tongue 8b arranged, and at the end a cutout 8c that fits into the support roller 11. The top-angle ridge element 8a is clearly shown in FIG. 9c.

Figs. lOa-lOd represent return support 9 in four different respects. The outline projection of FIG. lOa shows two noses 9a and cuts 9c and 9e between them. In the cutout 9e, two holes 9f are visible for the pulling springs 19. The cutout 9c serves for unobstructed passage of the rocking stem 6 square section (Figs. 1, 2). The external shape and cross-sectional shape of the return support 9 are clearly shown in FIG. lOa and lOb.

The return support 9 is guided by the stem 3 (Fig. 1) in the hole 9b.

Thanks to the release lever 60 (FIG. 1a-12b), which is adaptable to various conditions, the object of the invention can be easily adapted to almost any desired location.

This is also facilitated by the very design of the dispensing device 50, which as such has proven itself, by means of a rotary, i.e. after spraying the adjustable nozzle 52 in the valve body 51.

The design of the release lever 60 according to the drawings of FIG. lla and lla 'essentially corresponds to that shown in FIG. 5. As is simplified here, it concerns hinge 62. The halves 60 '60 of the lever housing (sketches FIG. 11b, FIGS) have additional bearing rings 60a, and in the lower part 60 an additional rib 60a' and in the upper part 60 'additional landmarks 60b for snail wheel 66 having switch noses 66a. The nozzles 60c in the lower housing half 60 are centered in the receiving lugs 60c 'in the housing half 60' and serve for proper connection by means of screws 65.

The ribbed ring 60a 'of FIG. Ilc is also used in the variant of FIGS. 13a and 13b.

According to the sketch of FIG. 13a, this release lever 60 is articulated and can be adjusted to bridge larger release distances. To this end, the two upper and lower lower half halves 60 'and 60 of the levers are screwed together at the desired angular position.

In limited space conditions, especially when the release lever has to be driven through the upper door slot, the release lever 71 'according to the drawings of FIG. 12a and 12b. Here, the hinge 62 is mounted in the yoke 70. The release wheel 61 'is smaller in diameter and is clean flat without any cutouts. The flat portion 71 'of the lever 71 is dimensioned such that it passes through the slot above the door without touching it. The release lever 71 can be mounted in any way on the opposite side of the door frame or on the door itself.

The possibility of universal incorporation of the object of the invention is clearly apparent from the drawings of FIG. 14-16c:

In FIG. 14, the room sprayer is normally screwed to the door leaf 72 in such a way that the door shimmer 73 looks into the room and the release lever 60 touches the door frame 72 'when the door is closed. If the door handle 74 is now opened normally, the spray process of FIG. 1 as shown in FIG. 15.

For completeness, the wall of the room is numbered 75.

As shown in the drawings of FIG. 16a-16c, the room sprayer 1 is attached directly to the door opening in wall 75. The door hinge 73 is also directly connected to wall 75.

Despite these very harsh mounting conditions, the release lever 60 can be precisely adjusted by turning the worm 67 using a notch resisting the notch in the stem 68, such as e.g. in FIG. Ilc. There is no additional wear and tear, since all the inaccuracies in closing the door are converted into rolling motion and thus into the movement / stroke of the release lever 60.

The object of the invention is expediently made of commonly available plastic. With the exception of stems / axles, gear parts (worm, worm wheel) and fasteners and springs, we can use proven and wear-resistant polymers.

The self-locking worm wheel 66 described above maintains the angular position of the release lever 60 relative to the impact lever 2, as adjusted according to geometric conditions, so that the room sprayer can operate for a long time without adjusting again.

With the presented variants of the lever, it is possible to practically solve all the upcoming installation problems.

The greatest advantage, however, is the possibility of installing a room sprayer 1 in any location without the spraying process adversely affecting people.

Small release and closing torques, as required, in most cases allow for easier installation of the device by connecting it with a double-sided adhesive mounting tape.

The purpose is also to adjust the angle of the release lever 60, as this indirectly, over the length of the path, reproduces the time delay of the spray process relative to the release based on the movement of the door.

The device according to the invention is obviously not limited to use in toilets and to integration by means of door movement. It can also be used in smoking rooms. It is also advisable to install a room sprayer in the areas of windows, blinds, flushing cisterns, etc., so that the spray process is started after aeration of the room or after flushing for the purpose of scenting the room.
