Description

Technical field

The present invention relates to a waste bin for used paper towels or the like, having an upper portion including a rear wall, two side walls and a front wall, the upper part including sealing means.

State of the art

Many public places, such as toilets at airports, train stations, hotels, department stores, etc., have paper towel dispensers. Such large establishments can have 500-1000 visitors over an eight-hour period. To reduce the time for filling paper towel dispensers over such a period of time, there is a tendency to create dispensers to hold an increasing number of towels. However, large distributors are of little use if garbage cans are not provided for storing an increased amount of used paper towels. Therefore, there is a need for garbage cans that can hold much more used paper towels than regular garbage cans, and yet are of moderate size.

It is known in the art to use sealing devices in garbage cans or in waste containers in order to reduce the amount of paper towels or other waste used, so that boxes or containers can contain much more paper towels or other waste.

Many of the known sealing devices consist of protruding parts on the lids that seal the waste in the drawer when the lid is closed, see, for example, EP-B1-0006242 and US 5440978. US 5884556 discloses a sealing device installed in a separate housing that can be inserted in a garbage container to compact its contents.

Japanese Patent Abstract No. 10-007204 discloses a waste bin having a lid that automatically opens when debris falls on it and a push plate that rotates from a standing position to a downward position. The lid, the pushing plate and its mechanisms are located in a separate unit, which is detachable from the rest of the garbage can. The disadvantage of this known waste bin is that the lid pushing the plate and its mechanisms occupy a lot of usable space in the bin. In addition, it is relatively difficult to empty the litter box.

An object of the present invention is to satisfy the aforementioned need by creating a trash can with a control means in which the sealing means slightly reduces the available volume inside the drawer and which allows emptying the drawer quickly and simply.

SUMMARY OF THE INVENTION

This problem is solved with the help of a waste bin for used paper towels or similar waste, having an upper part including a rear wall, two side walls and a front wall, the upper part including a sealing means, which is characterized in that the sealing means in its original position separates the inner space of the garbage bin to the upper and lower compartment and is made with the possibility of movement with the aim of opening and re-closing the hole in the lower part of the garbage can.

In one preferred embodiment, the sealing means consists of at least one plate, which from a closed initial position performs a rotary and linear movement to open and re-close the hole in the lower compartment, whereby the specified plate is rotated upside down (upside down) while moving from closed to re-closed position. At least one plate rotates in only one direction during successive movements from a closed to a re-closed position. At least one plate is preferably substantially rectangular, and the corners of said plate move along substantially rectilinear paths during the opening phase, and one pair of opposing plate angles moves along a circular arc during the re-closing phase, whereby the other pair of opposite corners forms the pivot axis for the plate during the re-closing phase. In addition, at least one plate has guide pins protruding from its corners in the direction of an adjacent side wall, while the side walls include guide rails in which said guide pins pass. The guide rails in the side walls are continuous and have a triangular shape. The guide groove for at least one plate is made in at least one of the side walls, and at least one plate has a follower element interacting with said cam curve.

In a first alternative embodiment, at least one plate extends horizontally in its closed and re-closed position.

In a second alternative embodiment, at least one plate is inclined downward from the front or rear wall in its closed or re-closed position.

The drive means for at least one plate are preferably supported by a side wall in the trash bin, while the drive means include at least one electric motor controlled by an electronic control means.

In a most preferred embodiment, the sealing means includes two plates that rotate in opposite directions during their movement from the closed to the re-closed position.

The lower compartment of the bin preferably includes a removable container that can be removed from the bin after opening or moving the bottom of the front or rear wall.

All movement of the sealing means between the closed and re-closed position occurs inside the specified upper compartment.

Description of Examples

Figure 1 shows in isometric projection the upper part of a preferred embodiment of a dustbin 1 according to this invention. The garbage can 1 comprises a rear wall 2, a front wall 3 and two side walls 4 and 5. The garbage can further includes sealing means in the form of two movable sealing plates 6, 7, which are in their initial position horizontally and separate the garbage can into the upper compartment 8 and lower compartment 9. In FIG. 1, walls 2-5 are shown transparent in order to be able to show the sealing plates 6, 7 in FIG. 1. Typically, these walls are made of opaque material.

On figa-2g schematically shows the movement of the sealing plates 6, 7 from the closed starting position, in which the plates 6, 7 form the bottom of the upper compartment 8, in the open position and back to the starting position. The corresponding opposite edges of the plates 6, 7 are indicated by 10, 11 and 12, 13, respectively.

2 a, the plates 6, 7 are shown in their closed initial position. When the mechanism for moving the plates 6, 7 is turned on, the corresponding plates are moved so that the longitudinal edges 10, 13 of the corresponding plate adjacent to the side wall 5 and 4, respectively, are moved upward, while the longitudinal edges 11, 12 of the respective plates, remote from the side walls, simultaneously move to the corresponding side wall 5 and 4, respectively. This movement pattern continues (see fig.2b and c), while one side of the plates 6, 7, i.e. in FIG. 2 a, the lower side of the plates does not abut against the corresponding lateral side 5, 4, as shown in FIG. 2 a. During the movement of the plates between the positions shown in figa-2a, i.e. in the phase of opening the movement of the plates, all used paper towels or similar debris present in the upper compartment 8 of the bin 1 falls down into the lower compartment 9 of the bin.

From the position shown in FIG. 2a, the plates 7, 6 are rotated downward to the horizontal position shown in FIG. 2g. As follows from figa-2g, this rotary movement is a purely rotational movement. During this movement, i.e. the phases of the re-closing movement, any towels or similar waste that protrudes upward from the lower compartment 9 of the drawer are pressed down into the indicated lower compartment by the plates 6, 7. When moving from the position shown in FIG. 2 a to the position of the plate 6 shown in FIG. , 7 turned upside down, so that the longitudinal edges 10, 13 of the corresponding plate adjacent to the corresponding side wall 5, 4 in the position shown in FIG. 2a are removed from the side walls in the position shown in FIG. 2g. During the next activation of the mechanism for moving the plates 6, 7, they move according to a pattern similar to that shown in figa-2g, and end the movement in the position shown in figa, in which the longitudinal edges 10, 13 of the corresponding plate 7 and 6 respectively, are again adjacent to the corresponding side wall 5, 4. During all their movements, the plates 6, 7 move only in the upper compartment 8 of the garbage can 1. As follows from figa-2g and the above explanation, the direction of rotation of each plate is always the same vim, namely, the plate 7 rotates clockwise, while the plate 6 rotates counterclockwise.

When used paper towels are thrown into the bin, their first fall into the lower compartment 9 is prevented by the sealing plates in the position shown in FIG. 2a or 2g. When a certain amount of used paper towels accumulates in the upper compartment 8 or after a certain time, the sealing plates are actuated to perform their movements in accordance with figa-2g. Then, the used towels fall from compartment 8 down to the lower compartment 9. When the upper compartment 8 is full again or after a certain amount of time has passed, the plates are again driven to carry out their movement pattern. This sequence of actions is repeated in time. After a certain number of times the used towels are emptied from the upper compartment to the lower compartment, towels falling into the lower compartment fill the compartment, and then towels thrown into the upper compartment remain therein while moving the sealing means from position 2a to position 2d in FIG. 2 in which the plates extend vertically with emphasis on the side walls of the upper compartment. During the pivoting movement of the plates from shown in FIG. 2a to shown in FIG. 2g, the towels in the upper compartment are sealed with plates and pressed into the lower compartment 9. This sequence of actions continues until the towels in the lower compartment are maximally compacted or until empty lower compartment. The term “maximally compacted” means that either the pressure force of the plates is too weak for further compaction of the towels, or the volume occupied by the towels is reduced to the maximum extent. The lower compartment of the drawer preferably comprises a bag or the like into which used towels from the upper compartment fall to facilitate emptying the trash can.

The trash can is preferably designed so that it can contain a certain amount of used paper towels, equal to or greater than the amount estimated to be thrown into the drawer during the period between two service intervals of the room in which the trash can is located. In this case, the used towels thrown into the upper compartment are held in it during the emptying of the lower compartment. Otherwise, if protective measures are not taken, the sealing plates will become stuck between 2d and 2g in FIG. 2 and there is a risk that used paper towels will fall to the bottom of the compartment or to the floor when the bag is removed from the lower compartment . These towels provide additional work for the staff serving the trash can. The mechanism for moving the sealing plates is controlled by an electronic control unit, and to prevent the risk of emptying towels from the upper compartment outside the bag in the lower compartment, the control unit can be designed to stop further activation of this mechanism when the compressed towels in the lower compartment exert a certain pressure on the sealing plates. At the same time, disabling this mechanism may trigger a signal, such as a red light, indicating that garbage must be removed.

As indicated above, the activation of the transfer mechanism for the sealing plates can preferably be controlled by a timer, so that the mechanism is activated after a certain period of time, for example, every ten minutes, in which case the upper compartment is sized to contain the used towels in an amount estimated to be used for that same time interval. To save battery power, the control unit may preferably comprise the “high load” and “low load” positions, where the “high load” position corresponds to the above defined time interval, for example ten minutes, and the “low load” position may correspond to a longer time, for example one hour or even more, for use at night and on weekends, when there is a very small number of visitors to the room in which the box is located.

However, the automatic actuation of the transfer mechanism for the sealing plates can also be controlled by means such as photocells detecting when the upper compartment is full of used towels.

If the trash can is located close to and serves one or more dispensers that can transmit electronic signals via cable or, for example, via infrared, indicating that towels are removed from the dispenser (s), then the trash can control unit can use these signals to count the number of towels towels and turning on the transfer mechanism for the sealing plates when a predetermined number of towels has been removed.

Such dispensers may measure the number of towels recoverable or the length of the towels recoverable.

If the trash can is served by only one such distributor, then the control unit of the distributor can perform the count, which can then transmit an enable signal to the control unit of the trash can.

In addition, the waste bin is preferably provided with a button (or the like) connected to the control unit for activating the moving mechanism for the sealing plates, so that they can be manually actuated. This allows maintenance personnel to empty the upper compartment from possible paper towels contained therein, into the lower compartment before emptying it.

Figure 3-6 schematically shows in isometric projection from above a mechanism 14 for moving the sealing plates 6, 7 with the plates in different positions. Fig. 3 shows the sealing plates in a position corresponding to the position in Fig. 2a, Fig. 4 shows the sealing plates in a position corresponding to the position in Fig. 2b, Fig. 5 shows the sealing plates in a position corresponding to the position in Fig. 2d , and FIG. 6 shows the sealing plates in a position corresponding to the position in FIG. 3-6, the walls of the box are not shown, with the exception of the part of each side wall 4, 5, on which the mechanism 14 is supported and which contain means for guiding the sealing plates 6, 7.

The mechanism 14 comprises an electric motor 15, a drive gear 16 fixed to the output shaft of the engine 15, and two identical gears 17, 18 in meshing with each other. The gear wheel 17 is meshed with the gear wheel 16 and is driven by it. The rod 20 is one of its ends rotatably connected to each gear 17, 18 near their outer periphery. The other ends of the rods 19, 20 extend in the guide groove 21 and 22, respectively, wherein said guide grooves are cut through the side wall 5. The ends of the rods 19, 20 extending in the guide grooves are rotatably connected to the corresponding sealing plate 6, 7. These swivel joints between the indicated ends of the rods 19, 20 and the adjacent short side of the corresponding plate 6, 7 are located at the midpoint of the short side of the corresponding plate 6, 7. In this case, the short side of the plate means its hundred it facing the side wall, regardless of the size of the plates. As shown in FIG. 3, both side walls 4, 5 are provided with guide grooves 21, 22, and both short sides of each sealing plate have pins or the like included in said guide grooves. In addition, each corner of each short side of each plate 6, 7 has an angular pin or an angled pin protruding from the corresponding short side in the longitudinal direction of the plates, i.e. in the direction of the adjacent side wall 4, 5. On each side wall 4, 5 there are triangular guide rails 23, 24 (only guide rails on the side wall 4 are shown in FIGS. 3-6), in which the indicated corner pins are guided. The triangular shape of the guide rails is formed by straight horizontal and vertical legs and a curved hypotenuse connecting the free ends of the legs. A curved hypotenuse consists of a circular arc. The guide rails are located facing each other hypotenuses, while one leg is located horizontally, and the other, respectively, vertically, as shown in Fig.3-6. In each horizontal corner of said triangular shape of the guide rails 23, 24, there are means for creating a counteracting force to the movement of the corner pins in the rails. These means consist of latch and spring locks or friction means between the corner pins and the rails or the side wall. A description of the functioning of these tools will be given below.

In figure 3, the sealing plates are shown in the closed initial position, and the engine 15 is turned off. When the engine is switched on by an electronic control unit (not shown in the figures), the gears 17, 18 begin to rotate in the directions indicated by the arrows in the figures, and the upper ends of the rods 19, 20 begin to move upward in the respective guide grooves 21, 22, moving the sealing plates through a swivel with the middle of their short side. The snap locks or the like in horizontal angles are arranged so that the counter force generated by them is greater in the horizontal angles between the hypotenuse and the horizontal leg than in the angles between the legs in the corresponding triangular guide rail 23, 24. Due to this, the outer longitudinal edge parts of the corresponding plate 6, 7, adjacent to the rear and front walls of the box, respectively, move more easily than the opposite internal parts. Due to this, it is ensured that the corner pins of the corresponding plate 6, 7 are moved in the parts of the legs of the guide rails and do not move in the hypotenous parts. Thus, turning on the motor 15 rotates the plates 6, 7 around the inner corner pins, while these pins simultaneously move outward, i.e. in the direction of the rear and front walls, respectively, in the guide rails. Figure 4 shows the position of the plates shortly after turning on the engine 15.

In Fig. 5, the upper ends of the rods 19, 20 have reached the upper ends of the guide grooves 21, 22, and the sealing plates are brought into a vertical position with an emphasis on the rear and front wall, respectively. In this vertical position, the corner pins of the sealing plates 6, 7, removed from the front and rear walls, respectively, in FIG. 3, have moved to the corners between the legs in the respective triangular guide rails 23, 24 and to the snap locks or the like located in these corners. Further rotation of the gears 17, 18 causes the upper ends of the rods 19, 20 to move downward in the guide grooves 21, 22 of their upper ends. This leads to the rotation of the sealing plates downward, while the corner pins of the plates, which, in the position shown in FIG. 5, are located in the corners between the vertical legs and the hypotenuses of the guide rails, are guided to the curved part of the corresponding rail. The reaction force acting on the corner pins located in the corners between the legs, due to snap locks or similar elements in these corners, provides such a movement of the plates.

When the plates have moved down to the horizontal position, while the corner pins on the corresponding plate are again in the snap locks in the position shown in Fig. 3, one cycle of the movements of the sealing plates is completed, and the engine 15 is turned off by the electronic control device. The position of the sealing plates 6, 7 in FIG. 6 corresponds to the position shown in FIG. 3, with the only difference being that the side of the plates, which in FIG. 3 is turned up, is turned down in FIG. 6. Opposite sides of the plates 6, 7 are indicated in figures 3-6 by the positions "A" and "B", respectively.

Plates 6, 7 with a rectangular cross section were disclosed. Naturally, other cross-sectional shapes are also possible. For example, plates may be thicker in their middle. The sides of the plates need not have smooth surfaces, but may have rough or uneven surfaces. The plates do not have to be exactly rectangular, you can give the plates a slightly curved (“fitted”) shape in order to prevent influence on the towels in the lower compartment from the side of the plates during their movement in the opening phase.

If the garbage bin 1 is not emptied in a timely manner, the number of used paper towels in the lower compartment will reach such a value that they can no longer be sealed with sealing plates. This condition can be achieved when the towels are packed as physically as possible, or when the maximum torque of the engine is reached. If you continue to turn on the engine in this condition, the engine may be damaged. Therefore, the mechanism for moving the sealing plates is preferably provided with means for turning off the electric motor 15 if the back pressure from the used paper towels in the lower compartment of the waste bin 1 exceeds a certain value. One way to implement such a tool is to measure the current supplied to the motor and turn off the motor when the current exceeds a certain value. Another way is to register the horizontal position of the sealing plates in any suitable way, such as the location of the indicators in the horizontal corners of the guide rails. If one or both plates do not reach their horizontal position at a certain time, then the engine 15 is turned off. A third way can be to estimate the time of one cycle of plate movements in order to determine when the counteracting force of used paper towels in the lower compartment reaches an acceptable value, and due to this decision on the maximum allowable start time of the engine 15.

It should be noted that for safety reasons, the torque of the engine 15 is preferably not so high that it was impossible to remove a hand caught between the plates turning downward, or so high that it could damage the hand. In order to further reduce the risk of such damage, an element of soft material such as rubber or the like may be attached to the longitudinal edge portions of the plates.

For proper operation of the mechanism according to the preferred embodiment and explained with reference to FIGS. 3-6, it is essential that the downward rotation of the sealing plates 6, 7 is completed before the engine 15 is turned off. For this reason, in the corners between the horizontal leg and the hypotenuse of each guide rail, at least position indicators are present to check the presence of the corner pins of the sealing plates in these corners of the guide rails before the engine 15 is stopped.

The trash can 1 can be equipped with a mechanism similar to the mechanism 14 described in relation to Figs. 3-6 on the opposite side wall 4. In this case, the operation of the electric motors of these two mechanisms should be synchronized.

The corner pins of the sealing plates 6, 7 preferably comprise rollers fixed for rotation on them, in order to ensure smooth movement in the guide rails 23, 24. Such rollers can be made of slightly elastic material, in which case the reaction forces in the horizontal corners of the guide rail can create by reducing the distance between the two protruding ribs forming the rails.

The mechanism 14 can naturally be modified without departing from the scope of the invention. For example, gears 16, 17, 18 can be replaced with friction wheels, i.e. wheels having a friction coating on their peripheral surfaces. In this case, the risk of engine damage is reduced when the back pressure from the used paper towels in the lower compartment is greater than the maximum pressing force of the sealing plates.

You can also use, of course, separate drive mechanisms for each plate. Separate motors can also be provided for pivoting the plates, which in this case must be synchronized with the motors for reciprocating movement of the central longitudinal axis of the plates in the guide grooves. In this case, snap locks or the like in the horizontal corners of the guide rails can be dispensed with.

The side walls of the waste bin 1 are preferably of double-walled construction so that the transfer mechanism 14, the electronic control unit and the power supply unit, such as one or more batteries, can be placed between these walls. Fig. 7 shows a schematic isometric view of a preferred embodiment of the bin 1. In this embodiment, the lower compartment of the bin includes a bag holding unit 25, which can be removed from the bin through a door 27 in the front wall 3. The bag holder 25 comprises a rear wall , two side walls and the bottom wall, and the opening part of the bag (not shown in the figure) can be folded over the upper edges of the back wall and side walls. A door providing access to the bag holder may naturally be located in the rear wall of the bin instead of the front wall, as shown in FIG.

The bag holder may naturally have other configurations. For example, the side walls may not be in the configuration shown in Fig. 7, in which case the upper part of the back wall of the holder may have an annular element over which the opening part of the bag can be folded. The back wall of the bag holder may form part of the back wall of the bin, in which case there is no need for a door in its front wall. The bag holder according to FIG. 7 can be provided with a front wall and be dimensioned such that the front and rear walls of the bag holder form parts of the front and rear walls of the trash can. The garbage can may also have a stationary lower compartment, and a part of the upper part located between the side walls of the side walls and containing the upper compartment of the drawer may be removable, for example, pivotally attached to the front or rear wall of the stationary lower compartment. In this case, the bag can be lifted from the box to empty the lower compartment.

Sealing paper towels can be done more efficiently if the towels are wet. Although the used paper towels thrown into the bin contain water, its quantity is too small, about 1-2 ml of water in each towel, to create ideal conditions for effective compaction. Therefore, it is preferable to provide a spray device in the upper compartment for wetting the used paper towels before emptying them from the upper compartment to the lower compartment. Thus, such a spray device must be turned on immediately before starting the engine to move the sealing plates. Water tanks for the spray device may be located between the double walls forming the side walls. Another possibility is to connect the spray device with cold water pipes in the room in which the trash can is located. In this case, the waste bin is preferably mounted on the wall. The amount of water supplied to paper towels in the upper compartment should not be so large that water is squeezed out of the towels during compaction. The danger of squeezing water from paper towels, depending on the sealing force and quality of the paper and the amount of water supplied to the towels, can be determined empirically.

You can also place the plate and the mechanism for their movement in a separate block, which is located in the bottom of the container. Such a block “floats” on a pile of used paper towels and lifts itself during the compaction phase when used towels are compressed into the space under such a block. With this design, the sealing force is the same inside the entire bin, and the vertical position of such a unit indicates the number of paper towels sealed. The advantage of such a “floating” unit is a uniform degree of compaction inside the garbage can. The sealing power of such a block depends on its weight. If this weight is insufficient to obtain the desired degree of compaction, then the unit can be controlled using a telescopic unit, successively raising the unit stepwise in small steps.

The trash can sealing plates of the present invention take up very little space and allow the use of the entire upper and lower compartment for storing used paper towels. In addition, since the sealing plates in their horizontal position ensure that the used towels do not protrude from the lower compartment into the upper compartment, emptying the lower compartment by removing the bag from the lower compartment towards the holder of the bag is quick and easy.

The described embodiments can, of course, be modified in many respects without departing from the scope of the invention. For example, instead of a bag holder, the lower compartment may consist of a container of disposable material such as cardboard or the like. The trash can may have a different shape than the shape shown in Fig.7. The electric motor can be enclosed in a capsule and separated from the rest of the moving mechanism and connected to the drive gear via magnetic coupling or the like. You can also use one plate instead of two plates, as in these embodiments. If desired, the plate or plates may be tilted downward from the adjacent front or rear wall in the initial position. In addition, the horizontal and vertical rails that guide the sealing plates during their movement in the opening phase should not be straight, but may have a slight curvature. Therefore, the invention is limited only by the text of the attached claims.
