Description

Hand-held and hand-guided tool device

Technical Field

The invention relates to a hand-held and hand-guided tool device, comprising: a housing having at least one handle means for a user; a drive device disposed in the housing; a battery for providing electrical energy; a battery housing portion for housing the battery in the built-in state, the battery being taken out from the battery housing portion in the taken-out state; at least one tool unit that can be driven by a drive, which tool unit comprises at least one tool, in particular for the separate processing of objects; a tool holder arranged on the housing, wherein the tool unit is partially arranged in the tool holder in the working position and is coupled to the drive device, and wherein the tool unit is removed in the released position of the tool holder.

Background

Due to the design of the tool unit, such a tool device can be, for example, an electric hedge trimmer, wherein the tool unit has at least one reciprocating knife, preferably two counter-driven knives, as a tool for separating tree branches and the like. The electrical energy for driving the device is provided by a battery occupying the inserted state. The tool arrangement may comprise a drive element which drives, in particular, at least one tool to reciprocate. If the battery is removed from the battery receptacle and assumes the removed state, the drive device cannot be supplied with electrical energy and the tool arrangement cannot be operated, so that at least one tool cannot be moved.

The tool unit can be removed from the tool holder, for example for maintenance, in particular for renewed sharpening. Alternatively or additionally, for example, there is the possibility of setting up different tool units, whereby different types of activities can be carried out with the tool device, as will be discussed below.

EP 1479284 a1 describes a lawnmower having a battery-operated electric motor.

Further embodiments of hand-held tool devices are described in EP 1424002 a1, JP 2008-.

Disclosure of Invention

The object of the present invention is to provide a tool device of the type mentioned in the introduction, which has increased operational safety.

This object is achieved according to the invention in a generic tool device in that the tool device comprises a blocking element which can be moved from a blocking position in which the tool unit is secured against removal in the tool receptacle into a release position in which the tool unit can be removed from the tool receptacle, and vice versa, wherein the blocking element can only be moved into the release position for releasing the tool receptacle after the battery has been removed from the battery receptacle in order to remove the tool unit.

In the tool device according to the invention, a blocking element is provided. The blocking element may occupy a blocking position. In the blocking position, the tool unit arranged in the tool receiver is fixed and cannot be removed from the tool receiver. In order to remove the tool unit, the blocking element must first be transferred into the release position. According to the invention, it is provided that the blocking element can only be brought into the release position when the battery is removed from the battery receptacle. The removal of the battery ensures that the drive is not electrically loaded and thus cannot start at least one tool. Thus, when the tool unit is taken out from the tool accommodating portion, the user can be prevented from accidentally moving the tool. This reduces the risk of injury to the user. The operational safety of the tool arrangement is thereby increased in comparison with generic tool arrangements.

It will be appreciated that the battery may preferably be designed to be rechargeable.

In a preferred embodiment of the tool device according to the invention, it is provided that the blocking element and the battery comprise or are configured with corresponding abutment elements which, in the inserted state of the battery and in the blocking position of the blocking element, abut one another and which do not pass from the blocking position into the release position as long as the battery is brought into the inserted state in the battery receptacle. In this case, it is provided in particular that the blocking element cannot even be moved until the battery assumes the inserted state, since the abutment elements of the blocking element and of the battery cooperate in such a way that the blocking element cannot be moved or substantially cannot be moved. The blocking element can be transferred from the blocking position into the release position only when the battery is in the removal state.

In a further advantageous embodiment of the tool device according to the invention, it is provided that the blocking element and the battery comprise or are designed with corresponding abutment elements which, when the battery is in the inserted state, come into abutment with one another when the blocking element is displaced from the blocking position in the direction of the release position, in which the tool holder is partially released but from which the tool unit cannot be removed, and prevent further movement of the blocking element. In such an embodiment, there is a possibility of moving the blocking element in the direction of the release position. Thereby, the tool receiving portion is partially released. However, the tool unit cannot still be removed from the tool holder and is prevented further by the blocking element. The blocking element and the corresponding abutment element of the battery cooperate and, after the movement of the blocking element, they abut against one another as long as the battery still occupies the inserted state. Only after removal of the battery can the blocking element be moved further up to the release position in order to remove the tool unit.

In the last-mentioned advantageous embodiment, for example, there may be a possibility of access to the tool unit arranged in the tool receptacle. It is conceivable that this is for example for maintenance purposes, for example for lubricating movable parts of the tool unit and/or of the drive device.

Advantageously, an electrical contact element is arranged in the battery receptacle for cooperation with the battery and covers the contact element when the blocking element is in the release position. Thereby, the contact element may preferably be protected from dust and/or moisture.

It can be provided that in the release position the blocking element completely covers the battery receptacle.

Advantageously, the at least one tool unit is independent of the housing part of the housing. For example, the smaller dimensions make it possible to provide advantages in terms of handling of the at least one tool unit. Advantageously, the manufacturing costs for the tool unit may be reduced. This is particularly advantageous if a plurality of tool units are provided in the tool device, and thus individual housing parts can be saved.

Advantageously, the blocking element comprises or forms a cover element which, in the blocking position, at least partially and preferably completely or substantially completely closes the tool receptacle. In this case, it is particularly preferably provided that the cover element covers a section of the tool unit arranged in the tool holder and blocks removal of this section of the tool unit from the tool holder.

Advantageously, the tool holder can be closed in a sealed manner by means of the cover element, in order to make it difficult or even prevent the ingress of dust and/or moisture into the tool holder.

If the cover element occupies the blocking position, it can preferably be secured in the blocking position by means of at least one locking element in order to prevent an unintentional movement from the blocking position into the release position. The manner in which the blocking element, in particular the cover element, is locked will be discussed below.

It can be provided that the cover element is designed flat at least on the side facing away from the tool holder. In this way, dirt is made difficult to adhere to the cover element and cleaning of the tool device is facilitated.

In order to facilitate the handling of the tool device, it is advantageous if the blocking element is designed to be movable relative to the housing for the purpose of being transferred from the blocking position into the release position and vice versa.

Advantageously, the cover element can be moved in a plane defined by the cover element, for example in the case of a flat design.

It has proven to be advantageous if the housing comprises or is configured with a guide device for the blocking element, in particular the cover element, for guiding the movement of the blocking element. The guide means facilitates the user to transfer the blocking element from the blocking position into the release position and preferably vice versa.

Advantageously, the battery can be removed from the battery receptacle in a removal direction, and the blocking element can be transferred from the blocking position into the release position in the removal direction. This facilitates the user handling the tool arrangement. Easy handling it is simple for the user to first transfer the battery in the removal direction into the removal state. Subsequently, the blocking element can be moved in the removal direction into the release position. The user can, conversely, preferably move the blocking element into the blocking position counter to the removal direction and insert the battery into the battery receptacle counter to the removal direction.

Advantageously, the blocking element is held captive on the housing. Preferably, the blocking element is preferably fixed to the housing irrespective of its positioning. For this purpose, the blocking element can engage with a guide formed by the housing, for example, regardless of its position. A stop element may be provided on the housing, for example, on which the blocking element impinges in the release position, in order to prevent further movement relative to the housing.

In a preferred embodiment, it can be provided that the housing has half shells which, when joined to one another, are formed with a recess between them, in which the blocking element is accommodated, and preferably with a stop element for the blocking element which occupies the release position. The blocking element is embedded, for example, between two sections of the housing which are spaced apart from one another and are separated by a recess, wherein each section is formed by one of the half shells. The edge of the recess preferably forms a guide for the blocking element. The stop element preferably limits the range of motion, in particular the path of movement of the element.

The blocking element is preferably arranged on a side of the housing remote from the handle device, in particular on the underside. This reduces the possibility of a user actuating an actuating element arranged on the handle device, with which the drive device can be actuated, when touching the blocking element.

Preferably, at least one insertion cavity for a user is formed between the tool unit arranged in the tool receptacle and the housing. This facilitates the user to remove the tool unit from the tool receiving portion.

For driving the at least one tool unit, the drive device preferably comprises a drive element. The drive element is coupled to or forms part of the drive motor, for example. In a preferred embodiment, the drive element can be designed in particular as a drive shaft or drive bolt which can be driven in rotation about an axis. For example, the drive element projects into the tool holder and is operatively connected to the tool unit there.

Advantageously, the at least one tool unit comprises at least one eccentric element coupled to the at least one tool, which is coupled directly or indirectly to a rotating drive element of the drive device arranged in the tool receptacle. The at least one eccentric element can be operatively connected to the drive element and thereby preferably rotate about an axis different from the axis of the drive element. Thus, at least one tool is made to perform a reciprocating motion.

Advantageously, the tool device comprises a first locking element which is arranged on the blocking element and cooperates with a corresponding second locking element arranged on the tool receptacle in order to fix the blocking element occupying the blocking position on the housing. By means of the locking element it can be ensured that the blocking element cannot be accidentally transferred from the blocking position into the release position.

Advantageously, the second locking element is held in a fixed position on the tool holder. This facilitates handling of the tool arrangement for locking the blocking element.

The locking element can be in a force-locking and/or form-locking state in the inserted state. For example, form-locking, snap-on connections, latching connections, etc. are conceivable.

It can be provided that the tool unit is acted upon by a force directed in the direction of the tool holder by means of the first locking element, so that the tool unit can be held in a fixed position in the tool holder by means of the locking element.

Advantageously, the first locking element is fixed to the blocking element and is preferably held captive on the blocking element.

In order to simplify the handling of the tool arrangement, it is advantageous if the first locking element can be actuated manually and without tools for locking with and unlocking the second locking element.

In a preferred embodiment of the tool apparatus according to the invention, the first locking element comprises a knob or is configured as such a knob.

For example, it can be provided that a recess is formed on the first locking element, into which recess the second locking element is introduced, wherein at least one web and a groove which are in engagement are arranged on the recess and on the second locking element. Advantageously, the second locking element is introduced into the recess when the blocking element is transferred into the blocking position. At least one strip is arranged on the recess, for example, which strip can engage in a groove on the second locking element. Or vice versa. As already mentioned, the recess can be shaped, for example, in sections in an arc-shaped manner when the knob is provided, so that the second locking element can be fixed to the first locking element by turning the knob.

Advantageously, the tool unit engages with the second locking element. This ensures the positioning of the tool unit in the tool holder.

Advantageously, a through-opening formed on the tool unit is provided through which the second locking element penetrates.

Advantageously, the tool device comprises an orientation element arranged at a distance from the second locking element, which orientation element is held in a fixed position on the tool receptacle and engages with the tool unit. This allows the positioning of the tool unit in the tool receptacle to be ensured.

For example, a through-opening formed on the tool unit is provided, through which the orientation element penetrates or into which the orientation element is inserted.

Advantageously, the tool unit engages with the second locking element and the orientation element.

The second locking element and the orientation element are advantageously designed as studs.

The tool device preferably comprises a plurality of tool units comprising tools which differ from each other in their type, their use and/or size.

It may be provided that a plurality of tools are arranged on the tool unit. For example, two cutters are provided on a hedge trimmer tool unit.

The at least one tool may for example be or comprise one of:

a cutting tool, in particular for configuring the tool device as a power hedge trimmer, which is also referred to at present as a "knife";

a saw blade, in particular for configuring the tool device as a knife saw;

scraping tools, for example for abrasive machining of objects;

grinding tools, for example for abrasive, cleaning or polishing machining of objects; and

-a sweeping tool.

Detailed Description

Two advantageous embodiments of the tool device according to the invention are described below. The same reference numerals are used for identical or functionally identical features and components. First, the tool apparatus partially shown in fig. 1 to 4 will be discussed. Further advantageous embodiments of the invention, partially or fully shown in fig. 5 to 7, are explained subsequently. Only essential differences from the embodiment according to fig. 1 to 4 are discussed here. The same advantages can be achieved with both embodiments.

Fig. 8 and 9 show partial views of a section of a tool unit and a drive mechanism for the tool unit, which can be used in both embodiments of the invention. The same applies to the locking mechanism shown in fig. 10 and 11. Therefore, the explanation with reference to fig. 8 to 11 is applicable to both embodiments.

The tool device according to the invention according to fig. 1 to 4 is occupied in its entirety by reference numeral 10. It is designed as an electric hedge trimmer and comprises a tool unit 12 with two tools 14, described below, which are in opposite directions, the tools 14 being cutting tools, also referred to as cutters 16 for separating small branches and the like. The tool unit 12 is only partially shown in fig. 1 to 4. Fig. 6 and 7 fully illustrate the tool unit 12.

The tool apparatus 10 further includes a housing 18. The housing 18 has two

housing halves

20, 22 which are joined to one another. The housing 18 has an upper side 24 and a lower side 26 and also has a rear side 28 and a front side 30.

At present, the position and orientation indication should be considered to relate to the intended use of the tool device 10. When used as intended, the user grasps the tool apparatus 10, particularly from the rear, such that the rear side 28 faces the user. The tool unit 12 protrudes from the front side 30. The upper side 24 is directed towards the user and the lower side 26 is directed away from the user.

A handle means 32 is provided which is formed by a recess in the housing 18. An actuating element 34 for activating the tool device 10 is arranged on the handle device 32. In addition, a further curved handle device 36 is provided, which serves for guiding the tool device 10.

A receiving space for the housing 18 is formed between the

housing half shells

20, 22. A drive device 38 for driving the tool 14 is accommodated in the accommodation space. The drive device 38 comprises, in particular, an electric motor 40 (fig. 8).

The electric motor 40 drives a drive element 42, which is designed in the present case in the form of a pin as a polygon with a non-circular cross section. The drive element 42 defines an axis 44.

In order to supply the drive 38 with electrical energy, the tool device 10 has a battery 46 which is rechargeable in the present case. The battery 46 is provided with a battery receiving portion 48 on the lower side 26 adjacent to the rear side 28 in the housing 18.

For example, the battery 46 can assume a removal state in which the battery is arranged in the battery receptacle 48 and is secured therein in a locking manner. The customer shifts the battery 46 to the removed state by removing the battery from the battery housing 48. In particular, the battery 46 is pulled out of the battery receptacle 48 in the removal direction 50.

In the inserted state, the electrical contact elements of the battery 46 can cooperate with the electrical contact elements 52 arranged on the battery receptacle 48. In the present case, the contact element 52 is arranged on the side of the battery receptacle 48 remote from the rear side 28 (fig. 2).

The tool receiver 54 is arranged on the underside 26 of the housing 18. The tool unit 12 can be partially accommodated in the tool holder 54 with the section 56 in the operating position. The tool unit 12 can be removed from the housing 18 by removing the section 56 from the tool holder 54. It is advantageous, for example, to separate the tool unit 12 from the housing 18 in order to carry out maintenance on the tool unit 12, in particular to sharpen the cutters 16.

Alternatively or additionally, it can be provided that different types of tool units are used in the tool device 10, which differ from one another with respect to the at least one tool 14.

The tool receptacle 54 adjoins the capacitor receptacle 48, viewed from the rear side 28 to the front side 30, and extends substantially as far as the front side 30.

In order to form the tool holder 54, a housing part 58 is inserted between the housing halves 20, 22 (fig. 4 and 8). For example, the electric motor 40 is held on the housing portion 58.

The housing portion 58 delimits the tool receptacle 54 upward in the height direction of the tool device 10. As shown in fig. 1-4, the housing portion 58 may be considered to constitute the "bottom" of the tool receptacle 54, since the tool apparatus 10 is typically flipped for maintenance purposes.

The tool receptacle 54 is delimited laterally by

edges

60 and 62 formed by the

housing half shells

20 and 22. The

edges

60, 62 project beyond the housing part 58, so that a recess 64 is formed between the edges between the

half shells

20, 22. On the front side 30, a lead-through 66 for the tool unit 12 is present.

For closing the tool holder 54, a cover element 68 is provided, which is a blocking element 69 according to the invention. The cover element 68 may be broadly considered as a housing portion 70 of the housing 18.

The cover element 68 is arranged on the underside 26 and is in the present case designed in the form of a plate. The cover element 68 is flat on the lower side 26, thereby making dust difficult to adhere and facilitating cleaning.

The cover element 68 is inserted into the recess 64, wherein the edges of the cover element 68 are coupled to the

edges

60, 62.

The cover element 68 is held on the

edges

60, 62 in a manner that can be moved relative to the housing 18. Here, the

edges

60, 62 form the guide means 72 and respectively the guide elements.

The cover element 68 can be movable relative to the housing 18 in the longitudinal direction of the tool device 10. There is a possibility to move the cover element 68 in the direction of the rear side 28. This corresponds to a movement in the removal direction 50. Conversely, the cover element 68 can be moved back in the direction of the front side 30 counter to the removal direction 50.

The cover element 68 is inserted between the half-

shells

20, 22 in such a way that it is held captive on the housing 18. The

half shells

20, 22 are formed with stop elements 74 on the

edges

60, 62, so that the cover element 68 can only be moved back up to the end of the tool receiver 54 and cannot be detached from the

edges

60, 62.

The forward path of movement of the cover member 68 is defined by a locking member 134 disposed on the tool receptacle 54, as will be discussed below.

The drive element 42 is guided through the housing part 58 and projects therefrom into the tool holder 54.

As can be seen in particular from fig. 8 and 9, the cutters 16 lie flush against one another. In the respective tool 16, a slot (not shown) extending in the longitudinal direction thereof is formed in the section 56 which can be inserted into the tool holder 54.

The tool 16 has a coupling element 76 on the section 56, a through-opening 78 being formed in the coupling element 76. In the present case, only the coupling element 76 with one through-opening 78 is shown in fig. 9. The through-opening 78 is non-circular and in the present case is formed, in particular, approximately oval.

The drive element 80 is inserted into the through-opening 78. The drive element 80 is in the present case a disc with a circular shape and forms an eccentric element. Two through openings 82 are formed eccentrically in the drive element 80. Two further through openings 84 are formed in the drive element 80 laterally next to the through opening 82.

The tool unit 12 comprises a retaining element 86 covering the tool 16. Two through-openings 88 are formed in the holding element 86, which are arranged at a distance from one another and are located above the elongated holes in the tool 16.

In addition, a through opening 90 is formed in the retaining link 86. In the through-opening 90, a connecting element 92, which is in the present case disk-shaped, is accommodated. A receiving portion 94 is formed at the center of the connecting link 92. The receptacle 94 is shaped in cross section such that it interacts with the drive element 42. The drive element 42 rotating about the axis 44 can thus also drive the connecting link 92 in rotation about the axis 44.

Laterally next to the receptacle 94, a through-opening 96 is formed in the connecting link 92. The through openings 96 may be aligned with the through openings 84 of the two drive links 80.

The fastening element 98, which is in the form of a pin, penetrates through the through-opening 96 of the connecting element 92 and the through-opening 84 of the drive element 80 and is fastened by force or form-locking in such a way that the drive element 80 and the connecting element 92 are connected to one another.

The drive elements 42 penetrate through respectively different through-openings 82 in the drive segments 80, so that the drive segments 80 are not stacked on top of one another in alignment. Instead, the drive elements 80 are each positioned eccentrically with respect to the drive element 42, but in opposite directions to one another.

When the drive element 42 rotates, the drive elements 80 thereby rotate eccentrically about the axis 44 and move the tool 16 in opposite directions.

The tool unit 12 further comprises a profiled reinforcing element 100 which is placed on the housing part 58 and engages with it in a form-locking manner. Thereby, the tool unit 12 is reliably held in the tool accommodating portion 54 in both the longitudinal direction and the lateral direction.

An orientation element 102 shaped as a stud 104 is arranged in a positionally fixed manner above the housing part 58. The stud 104 penetrates through the elongated hole of the tool 16 and one of the through openings 88 and serves to additionally fix the tool unit 12 in the tool holder 54. A further azimuthally fixed orientation element 106 is arranged at a distance from the orientation element 102 and is also designed as a peg 108. The stud 108 also penetrates through the long hole of the tool 16 and the other of the through openings 88 therein.

As can be seen in particular from fig. 3, the section 56 is arranged in the tool receptacle 54 in the working position of the tool unit 12. The tool unit 12 is thus in engagement with the drive element 42 and the two

pegs

104 and 108. The tool 16 and the reinforcing element 100 penetrate through the lead-through 66 and project from the housing 18.

The cover element 68 may occupy the blocking position. The blocking position of the cover element 68 is shown in fig. 1 and 2. In the blocking position, the cover element 68 covers the tool holder 54 and the section 56 of the tool unit 12 contained therein. If the cover element 68 assumes the blocking position, the tool unit 12 cannot be removed from the tool receiver 54, so that the designation blocking element 69 is laid.

The tool unit 12 can only be removed from the tool receiver 54 after the cover element 68 has been moved from the blocking position into the release position. If the cover element 68 occupies the release position, the cover element 68 is moved relative to the housing 18 to such an extent that the removal opening of the tool receiver 54 is exposed, in order to enable removal of the tool unit 12 (fig. 3 and 4). In the release position of the cover element 68, the tool unit 12 or another type of tool unit can be inserted into the empty tool receptacle 54.

In the present invention, there is the particular advantage that the cover element 68 can be moved into the release position only when the battery 46 is removed from the battery receptacle 48.

If the battery 46 is in the inserted state in the battery receptacle 48, this is not possible. The battery 46 and the cover element 68 comprise corresponding

abutment elements

110 and 112, the abutment elements 110 being arranged on the end side of the battery 46 facing the cover element 68. The abutment element 112 is arranged on the end face of the cover element 68 facing the battery 46.

In the blocking position of the cover element 68, the

abutment elements

110, 112 abut against one another when the battery 46 is inserted into the battery receptacle 48 (fig. 1). This prevents the cover member 68 from moving. For this purpose, the battery 46 is first removed from the battery receiving portion 48. Thereby, the battery housing 48 is exposed (fig. 2). Subsequently, the cover element 68 can be moved from the blocking position covering the section 56 and closing the tool receiver 54, in this example above the battery receiver 48, and into a movement-release position, with which the tool unit 12 can be removed (fig. 3 and 4).

For mounting and dismounting, it is advantageous if the removal of the battery 46 and the displacement of the cover element 68 take place in both cases in the removal direction 50.

The advantage in the release position is that the cover element 68 at least partially covers the battery receptacle 48 to such an extent that it covers the contact element 52. Thereby protecting the contact element 52 from dust and moisture. As can be seen from fig. 3 and 4, in the tool device 10, the battery receptacle 48 is even substantially completely covered.

The embodiment of the tool arrangement according to the invention shown in fig. 5 to 7 and designated by reference numeral 120 differs from the tool arrangement 10, for example, in the last-mentioned respect. As can be seen from fig. 5 to 7, in the tool device 120, the housing 18 is designed to be longer than the housing of the tool device 10. Upstream of the handle device 32, a housing section 122 is arranged. The front and rear sections of the housing 18 in the longitudinal direction are designed identically to the housing 18 of the tool device 10.

In the tool device 120, the cover element 68 therefore only partially covers the battery receptacle 48 in the release position.

A further difference between the

tool arrangements

10 and 120 is that, in the tool arrangement 120, the cover element 68 can be moved from the blocking position in the direction of the release position. However, the release position can only be assumed when the battery 46 is removed as in the tool device 10.

Fig. 5 shows this situation, in which the cover element 68 is moved out of the blocking position until the

abutment elements

110, 112 are in abutment, and the battery 46 prevents further movement of the cover element 68.

In this case, the tool receiving portion 54 is partially released, but the tool unit 12 cannot be taken out therefrom.

The cover element 68 can be locked in the blocking position by means of a locking device 130. This ensures that the cover element 68 is prevented from being undesirably and erroneously moved into the release position. The locking device 130 includes a first locking element 132 and a second locking element 134.

The locking element 132 is arranged on the cover element 68 and in particular fastened thereto. The locking element 132 is designed as a knob 138 that can be turned about the axis 136. The axis 136 is perpendicular to the plane of the cover member 68. Knob 138 may be manipulated manually and without tools.

As can be seen in particular from fig. 10 and 11, a recess 140 in the form of a notch is formed on the knob 138. The recess 140 includes a radial section 142 and an arcuate section 144 that extend radially or in a circumferential direction of the axis 136. On the edge of the arc-shaped section 144, a strip 146 is arranged.

The second locking element 134 is currently formed by the stud 108. The locking element 134 includes an annular groove 148 near the free end.

When the cover element 68 is closed, the radial section 142 is oriented towards the locking element 134. Thereby, the locking element 134 is allowed to be embedded in the recess 140. This is shown in fig. 10.

Locking member 134 may be introduced into arcuate section 144 by rotating knob 138 about axis 136 (as indicated by arrow 150 in fig. 10). The strip 146 is therefore inserted in the groove 148 in a form-locking manner and the locking

elements

132, 134 are held together by the form-locking. This state is shown in fig. 2 to 4 and 11.

Conversely, when unlocked, knob 138 is rotated against arrow direction 150 until the locking element reaches into radial section 142. Subsequently, when the battery 46 is removed, the cover element 68 can be transferred from the blocking position into the release position.
