DESCRIPTION OF THE PREFERRED EMBODIMENTS
~igures 1 to 16 show a cutting device according to an embodiment of the present invention. Referring to Figs. 1 and 2, a cutting device is generally indicated by reference numeral 1. A cup-shaped lower housing 2 for storing cut pieces of vegetable is mounted on a fixing apparatus 3 which fixes the lower housing 2 onto a base plate by a sucker member 4 manually operated by a lever 5. An inverted cup-shape upper housing 6 is placed on the lower housing 2 and covers an opening thereof. The upper housing 6 is detachably intercon-nected to the lower housing 2 by a pair of connectingapparatuses 7. A cutter disk 8 fitted with cutter blades 9 is arranged in the lower housing 2. The cutter disk 8 is rotatable about the central axis of the lower housing, and is rotated by a handle 10 attached outside of the upper housing 6. An inlet 11 is formed in the upper housing 6 for supplying the vegetable to be cut to the cutter disk 8.
Fig. 3 shows a sectional vle~ of -the cut-ting device 1, and Fig. 4 shows the same in a disassembled state. The lower housing 2 has an upper peripheral portion 20 which defines the opening, and has a tubular guide 21 which surrounds the axis of the housinq. A
lower peripheral portion 22 of the upper housing 6 is engagable with the inside of the upper peripheral portion 20, and the lower peripheral portion 22 is fixed to the upper peripheral portion 20 by the connecting aPparatus 7.
The cutter disk 8 is detachably arranged at the opening of the lower housing 2, and a lower face thereof defines a storage chamber 23 in an interior of the lower housing 2. The cutter disk 8 is rotably supported by a pin 24 mounted on a projection 25 formed on an upper plate of a casing 26 of the fixing apparatus 3. That is, the cutter disk 8 has a downward extending spindle 27 in which a bore 28 and a hole 29 are formed, while the projection 25 extends toward the hole 29 and the pin 24 rotatably engages with the hole 29. Thus, the pin 25 extends along the axis of the lower housing 2, and is inserted into the hole 29, which has a diameter smaller than that of the bore 28. The cutter disk 8 is detacha-ble from the pin 24. A washer 30 is inserted between the spindle 27 and the projection 25, to reduce friction therebetween. The tubular guide 21 surrounds the spindle 27 and the projection 25.
The cutter disk 8 is driven by the handle 10 to rotate about the axis of the lower housing 2. For this purpose, a first drive shaft 31 is rotatably supported by a box 32 formed in the upper housing S. The drive shaft 31 has a lower engaging portion 33 which is non-rotatably and detachably fitted into the bore 28 of the cutter disk 8. That is, the lower engaging portion 33 has a polygonal cross-section (e.g., a square cross~section), and the bore 28 has the correspondent cross-sectlon (see Fig. 5). Therefore, when the drive shaft 31 is rotated by the handle 10, at least one flat surface of the lower engaging portion 33 engages with a flat surface of the bore 28, so that the shaft 31 rotates the cutter disk 8. Note, the lower engaging portion 33 has a tapered end portion 34 which converges downward so that the lower engaying portion 33 is easily inserted into the bore 28.
The handle 10 is rotatably attached to a side wall of the upper housing 6. A second drive shaft 35 con-nected to the handle 10 is provided with a second bevelgear 36 which is housed in the box 3~ and engages with a first bevel gear 37 fixed onto the first drive shaft 31.
Thus, a drive means is constructed from the first and second drive shafts 31, 35, the first and second bevel gears 37, 36, and the handle 10.
A pair of slots 40 are formed in the cutter disk 8, these slots extend in a substantially radial direction, as shown in Fig. 5. Each cutter blade 9 is arranged in the slots 40, respectively, and is fixed to a lower face of the disk 8 by a retainer plate 41 and a screw 42, as shown in Fig. 6. A cutting edge 49 of the cutter blade 9 projects from the upper surface of the cutter disk 8 in such a manner that the edge 49 will cut or slice a vegetable. The retainer plate 41 is supported 25 by a rim 43 formed on the lower face of the disk 8. The cutter disk 8 has annular ribs 44, 45 which protrude from the lower face thereof. These ribs 4d, 45 are concentric with and provide rigidity to the disk 8.
The upper housing 6 has a downward extending tubular 30 wall 46 terminating in the vicinity of an upper face of the disk 8. The tubular wall 46 defines the inlet 11, which the upper face of the disk 8 faces. The inlet 11 is formed at a half part of the upper housing 6, but is not formed at the box. Thus, the inlet 11 is opened along the rotational direction of the disk 8.
A pushdown member 47 may be provided for pressing a vegetable inserted in the inlet 11 onto the upper face of the cutter disk 8. The pushdown member 47 is formed into a shape that conforms to the shape of the inlet 11, and has a head portion 48 for manual handling, as shown in Figs. 7 and 8.
The fixing apparatus 3 comprises the casing 26, the sucker member 4, and the manual lever 5, as previously mentioned, and is attached to a bottom face of the lower housing 2 by inserting claws 60 formed on a bottom surface of the lower housing 2 into holes (not shown) opened in the casing 26.
The sucker member 4 is made of an elastic material such as a rubber, and is formed into an inverted disk-shape. The sucker member 4 has a concave central portion 50 and a ring-shaped peripheral flat portion 51, a lower surface of which will make a sealed contact with a base plate. An upper surface of the flat portion 51 is supported by the casing 26 so that the lower surface of the flat portion 51 makes a sealed contact with the base plate. The sucker member 4 is formed with an upward extending first annular rib 52 in contact with the casing 26, and an upward extending second annular rib 53 radially and outwardly spaced from the first annular rib 52.
The casing 26 has a downwarcl extending enclosure 54 at a peripheral portion, and a downward extending annular wall 55 inside of the enclosure 54. A lower end portion of the annular wall 55 is in contact with the upper face of the flat portion 51 of the sucker member 4, and an outer surface of the annular wall 55 is engaged with the inside of the first annular rib 52.
The manual lever 5 penetrates the annular wall 55, and a knob 56 of the lever 5 projects from the enclosure, whereby the lever 5 is rotably supported by the casing 26. The manual lever 5 has a crank portion 57 connected to a joint member 58 fixed to the c~ntral portion of the sucker member 4. As shown in Figs. 9 and 10, the joint member 58 has a disk plate 61 fixed to the central ~2~
portion of the sucker memb-er 4 and a projection 62 extending upward on the disk plate 61, and a hole 63 is formed in the projection 62. The crank portion 57 of the lever 5 is inserted in the hole 63 of the joint member 58. The lever 5 actuates the central portion up and down as follows.
Fig. 9 shows a state in which the central portion of the sucker member 4 is lowered, that is, the fixing apparatus 3 is not operative. In this state, the crank portion 57 is located in a lower position so that the joint member 58, i.e., the central portion of the sucker member 4 is lowered. Consequently, a space 64, defined by the sucker member ~ and the base plate, has a rela-tively small volume. To the contrary, if the lever 5 is rotated about 180, the crank portion 57 is moved upward so that the central portion of the sucker member 4 is raised, as shown in Fig. 10. Accordingly, the volume of the space 64 is enlarged so that a vacuum is formed in the space 64, and the flat portion 51 of the sucker 20 member 4 makes a sealed contact with the base plate, whereby the fixing apparatus 3 sticks to the base plate.
In this operation, since the first annular rib 52 engages with the outer surface of the wall 55, the flat portion 51 does not move inwards, and, since the flat portion 51 has a relatively wide breadth and is formed with the second annular rib 53, the rigidity of the flat portion 51 is increased and the flat portion 51 is placed in firm contact with the base plate, and will not separate from the base plate. The fixing apparatus 3 is released from the base plate by rotating the lever 5 to a position shown in Fig. 9.
As mentioned above, the cutting device comprises the upper housing 6, the cutter disk 8, the lower housing 2, and the fixing apparatus 3, and these com-35 ponents can be disassembled as shown in Fig. 4. Theupper housing 6 is removed from the lower housing 2 and the cutter disk 8 by releasing the connecting æ
apparatuses 7 (see Fig. 1, described in detail herein-after) and drawing the engaaing portion 33 from the bore 28 of the cutter disk 8. The cutter disk 8 is removed by lifting it off of the pin 24. The lower housing 2 is detached from the fixing apparatus 3 by drawing the claws 60 from the holes formed in the casing 26. In this disassembling operation, the fixing apparatus 3 may remain in sealed contact with the base plate.
Since the cutter disk 8 can be detached from the lower housing 2, and the lower housing 2 can be removed from the fixing apparatus 3, any cut pieces of vegetable stored in the lower housing 2 are easily removed, and it is easy to wash the lower housing 2 after use.
The cutting device can be quickly re-assembled by mounting the lower housing 2 on the fixing apparatus 3, arranging the cutter disk 8 in the lower housing 2, and engaging the upper housing with the lower housing 2.
The cutter disk 8 is easily changed for another kind of cutter disk according to the purpose for which the device will be used. The spindle 27 is rotatably supported by the projection 25 and the pin 24, and the bore 28 is engaged with the lower engaging portion 33 of the drive shaft 31. That is, the cutter disk 8 is ~5 supported at two points, ensuring a stable rotation of the cutter disk 8 when cutting a vegetable.
Note, the lower housing 2, the upper housing 6, the disk 8, the casing 26, the pin 24, the bevel gears 36, 37, the lower engaging portion 33 of the shaft, the handle 10, and the pushdown member 47 are all made of plastic.
Figure 11 to 16 show the construction and operation of the connecting apparatus 7. Referring to Fig. 11, after mounting the lower housing 2 on the fixing appa-ratus 3, and arranging the cutter disk (not shown) inthe lower housing 2, the lower peripheral portion 70 of the upper housing 6 is fitted into the upper peripheral portion 71 of the lower housing 2. Flrst the projection 72 formed on the lower peripheral portion 70 engage with L-shaped slots 73 formed on the upper peripheral portion 71, by moving the upper housing 6 downward along the axis thereofO The L-shaped slot 73 has a substan-tially vertical portion 74 and a substantially horizontal portion 75, and the projection 72 enters the vertical portion first. The upper housing 6 is then slightly rotated about the axis thereof, in relation to the lower housing 2, so that the connecting apparatuses 7 lock both the housings 2 and 6, as described later.
A pair of connecting apparatuses 7 are mounted on the upper housing 6 at opposite sides (see Fig. 2), respectively, and prevent the projections 72 from being dislodged from the L-shaped slots 73. The connecting apparatus 7 has a pawl 80 engagable with the vertical portion 74 of the L-shaped slot 73. The pawl 80 is located in the upper housing 6, and pro~ects therefrom through an opening 81 formed in the lower peripheral portion 70, so that the pawl 80 engages with the vertical portion 74 of the L-shaped slot 73, as shown in Figs. 12 and 13.
The connecting apparatus 7 comprises an inner member 82 arranged on an inner wall of the upper housing 6, an outer member, i.e., a manual lever 83 arranged on an outer wall of the upper housing 6, and a plate-shaped spring 84 inserted between the upper housing 6 and the manual lever 83, as shown in Figs. 14 and 15. While the upper housing 6 is formed with a first hole 85 and a second hole 86 vertically aligned with and spaced downward from the first hole 85, the manual lever 83 has a first connecting rod member 87 and a second connecting rod member 88 extending through the first hole 85 and the second hole 86, respectively.
The first connecting rod member 87 engages with an opening 89 formed in the inner member 82, and the second connecting rod member 88 is fixed to a surface of the 7~2 - 10 ~
inner member 82 by a screw 90, whereby the manual lever 83 and the inner member 82 are interconnected to each other. The inner member 82 and manual lever 83 are pivotally supported on the upper housing 6 with respect to the first connecting rod member 87, and are biased outwardly by the plate spring 84.
The pawl 80 is formed on the inner member 82 as shown in Fig. 16, and is located beneath the second connecting rod member 88. The pawl 80 has an inclined surface 91 directed downward, so that the pawl 80 can slide on an inner surface of the lower housing 2 when the upper housing 6 is fitted in the lower housing 2.
The plate spring 84 is bent into an arc-like shape in a free state, as shown in Fig. 16. The plate spring 84 has, at opposed ends thereof, a first cutaway portion 92 and a second cutaway portion 93, which are engagable with the first connecting rod member 87 and the second connecting rod member 88, respectively. The spring 84 is mounted between the manual lever 83 and the upper housing 6 so that a convex surface of the spring 84 is in contact with the manual lever 83.
To assemble the connecting apparatus 7, first the plate spring 84 is attached to the manual lever 83, and then the lever 83 with the spring 84 attached is mounted on the upper housing 6; the first and second rod members 87, 88 being inserted in the firs-t and second holes 85, 86, respectively. Next~ the opening 89 is engaged with the rod member 87, and an inner periphery of the opening 89 is fitted in a notch 94 of the rod me~ber 87, then the inner member 82 is fixed to the second rod member 88 by the screw 90.
In a non-operative state, the connecting apparatus 7 is biased outward so that a lower end of the manual lever 83 is situated away from the lower peripheral portion of the upper housing 6, and the pawl 80 is projected through the opening 81. The manual lever 83 is longer than the inner member 82, so the pawl 80 is hidden by the lower end of the lever 83 (see Fig. 12).
When the upper housing 6 ls engaged with the lower housing 2, first, the projection 72 is fitted to the vertical portion 74 of the L-shaped slot 73, then the upper housing 6 is rotated until the pawl 80 engages with the horizontal portion 74 of the L-shaped slot 73 and the projection 72 enters the hori20ntal portion 75 of the slot 73. In this state, the pawl 72 prevents the upper housing 6 from rotating relative to the lower housing 2, so that the projection 72 remains engaged with the L-shaped slot 73 to prevent the upper housing 6 from being removed from the lower housing 2.
On the other hand, when the upper housing 6 is disengaged from the lower housing 2, the manual lever 83 is manually pushed toward the upper housing 6, against the spring 84, as shown in Fig. 15. As a result, the pawl 80 is released from the L-shaped slot 73, as shown in Fig. 15, and the upper housing 6 is rotated so that the projection 72 engages with the vertical portion 74 of the L-shaped slot 73. The upper housing 6 is then moved upward while the projection 72 is guided by the vertical portion 74, and the housing 6 is detached from the lower housing 2. Note, a depression 95 may be forme~ at a lower portion of the manual lever 83 to facilitate manual pushing.
While embodiments of the present invention have been described herein with reference to the attached drawings, many modifications and changes may be made by those skilled in this art without departing from the scope of the invention.
Thus/ the cutting device must be able to be easily assembled for cutting a vegetable, and easily disassembled for removing the cut pieces of vegetable from the housing, and for washing the housing and other parts of the device.

The cutter disk 8 is detachably arranged at the opening of the lower housing 2, and a lower face thereof defines a storage chamber 23 in an interior of the lower housing 2. The cutter disk 8 is rotably supported by a pin 24 mounted on a projection 25 formed on an upper plate of a casing 26 of the fixing apparatus 3. That is, the cutter disk 8 has a downward extending spindle 27 in which a bore 28 and a hole 29 are formed, while the projection 25 extends toward the hole 29 and the pin 24 rotatably engages with the hole 29. Thus, the pin 25 extends along the axis of the lower housing 2, and is inserted into the hole 29, which has a diameter smaller than that of the bore 28. The cutter disk 8 is detacha-ble from the pin 24. A washer 30 is inserted between the spindle 27 and the projection 25, to reduce friction therebetween. The tubular guide 21 surrounds the spindle 27 and the projection 25.
The cutter disk 8 is driven by the handle 10 to rotate about the axis of the lower housing 2. For this purpose, a first drive shaft 31 is rotatably supported by a box 32 formed in the upper housing S. The drive shaft 31 has a lower engaging portion 33 which is non-rotatably and detachably fitted into the bore 28 of the cutter disk 8. That is, the lower engaging portion 33 has a polygonal cross-section (e.g., a square cross~section), and the bore 28 has the correspondent cross-sectlon (see Fig. 5). Therefore, when the drive shaft 31 is rotated by the handle 10, at least one flat surface of the lower engaging portion 33 engages with a flat surface of the bore 28, so that the shaft 31 rotates the cutter disk 8. Note, the lower engaging portion 33 has a tapered end portion 34 which converges downward so that the lower engaying portion 33 is easily inserted into the bore 28.
The handle 10 is rotatably attached to a side wall of the upper housing 6. A second drive shaft 35 con-nected to the handle 10 is provided with a second bevelgear 36 which is housed in the box 3~ and engages with a first bevel gear 37 fixed onto the first drive shaft 31.
Thus, a drive means is constructed from the first and second drive shafts 31, 35, the first and second bevel gears 37, 36, and the handle 10.
A pair of slots 40 are formed in the cutter disk 8, these slots extend in a substantially radial direction, as shown in Fig. 5. Each cutter blade 9 is arranged in the slots 40, respectively, and is fixed to a lower face of the disk 8 by a retainer plate 41 and a screw 42, as shown in Fig. 6. A cutting edge 49 of the cutter blade 9 projects from the upper surface of the cutter disk 8 in such a manner that the edge 49 will cut or slice a vegetable. The retainer plate 41 is supported 25 by a rim 43 formed on the lower face of the disk 8. The cutter disk 8 has annular ribs 44, 45 which protrude from the lower face thereof. These ribs 4d, 45 are concentric with and provide rigidity to the disk 8.
The upper housing 6 has a downward extending tubular 30 wall 46 terminating in the vicinity of an upper face of the disk 8. The tubular wall 46 defines the inlet 11, which the upper face of the disk 8 faces. The inlet 11 is formed at a half part of the upper housing 6, but is not formed at the box. Thus, the inlet 11 is opened along the rotational direction of the disk 8.
A pushdown member 47 may be provided for pressing a vegetable inserted in the inlet 11 onto the upper face of the cutter disk 8. The pushdown member 47 is formed into a shape that conforms to the shape of the inlet 11, and has a head portion 48 for manual handling, as shown in Figs. 7 and 8.
The fixing apparatus 3 comprises the casing 26, the sucker member 4, and the manual lever 5, as previously mentioned, and is attached to a bottom face of the lower housing 2 by inserting claws 60 formed on a bottom surface of the lower housing 2 into holes (not shown) opened in the casing 26.
The sucker member 4 is made of an elastic material such as a rubber, and is formed into an inverted disk-shape. The sucker member 4 has a concave central portion 50 and a ring-shaped peripheral flat portion 51, a lower surface of which will make a sealed contact with a base plate. An upper surface of the flat portion 51 is supported by the casing 26 so that the lower surface of the flat portion 51 makes a sealed contact with the base plate. The sucker member 4 is formed with an upward extending first annular rib 52 in contact with the casing 26, and an upward extending second annular rib 53 radially and outwardly spaced from the first annular rib 52.
The casing 26 has a downwarcl extending enclosure 54 at a peripheral portion, and a downward extending annular wall 55 inside of the enclosure 54. A lower end portion of the annular wall 55 is in contact with the upper face of the flat portion 51 of the sucker member 4, and an outer surface of the annular wall 55 is engaged with the inside of the first annular rib 52.
The manual lever 5 penetrates the annular wall 55, and a knob 56 of the lever 5 projects from the enclosure, whereby the lever 5 is rotably supported by the casing 26. The manual lever 5 has a crank portion 57 connected to a joint member 58 fixed to the c~ntral portion of the sucker member 4. As shown in Figs. 9 and 10, the joint member 58 has a disk plate 61 fixed to the central ~2~
portion of the sucker memb-er 4 and a projection 62 extending upward on the disk plate 61, and a hole 63 is formed in the projection 62. The crank portion 57 of the lever 5 is inserted in the hole 63 of the joint member 58. The lever 5 actuates the central portion up and down as follows.
Fig. 9 shows a state in which the central portion of the sucker member 4 is lowered, that is, the fixing apparatus 3 is not operative. In this state, the crank portion 57 is located in a lower position so that the joint member 58, i.e., the central portion of the sucker member 4 is lowered. Consequently, a space 64, defined by the sucker member ~ and the base plate, has a rela-tively small volume. To the contrary, if the lever 5 is rotated about 180, the crank portion 57 is moved upward so that the central portion of the sucker member 4 is raised, as shown in Fig. 10. Accordingly, the volume of the space 64 is enlarged so that a vacuum is formed in the space 64, and the flat portion 51 of the sucker 20 member 4 makes a sealed contact with the base plate, whereby the fixing apparatus 3 sticks to the base plate.
In this operation, since the first annular rib 52 engages with the outer surface of the wall 55, the flat portion 51 does not move inwards, and, since the flat portion 51 has a relatively wide breadth and is formed with the second annular rib 53, the rigidity of the flat portion 51 is increased and the flat portion 51 is placed in firm contact with the base plate, and will not separate from the base plate. The fixing apparatus 3 is released from the base plate by rotating the lever 5 to a position shown in Fig. 9.
As mentioned above, the cutting device comprises the upper housing 6, the cutter disk 8, the lower housing 2, and the fixing apparatus 3, and these com-35 ponents can be disassembled as shown in Fig. 4. Theupper housing 6 is removed from the lower housing 2 and the cutter disk 8 by releasing the connecting æ
apparatuses 7 (see Fig. 1, described in detail herein-after) and drawing the engaaing portion 33 from the bore 28 of the cutter disk 8. The cutter disk 8 is removed by lifting it off of the pin 24. The lower housing 2 is detached from the fixing apparatus 3 by drawing the claws 60 from the holes formed in the casing 26. In this disassembling operation, the fixing apparatus 3 may remain in sealed contact with the base plate.
Since the cutter disk 8 can be detached from the lower housing 2, and the lower housing 2 can be removed from the fixing apparatus 3, any cut pieces of vegetable stored in the lower housing 2 are easily removed, and it is easy to wash the lower housing 2 after use.
The cutting device can be quickly re-assembled by mounting the lower housing 2 on the fixing apparatus 3, arranging the cutter disk 8 in the lower housing 2, and engaging the upper housing with the lower housing 2.
The cutter disk 8 is easily changed for another kind of cutter disk according to the purpose for which the device will be used. The spindle 27 is rotatably supported by the projection 25 and the pin 24, and the bore 28 is engaged with the lower engaging portion 33 of the drive shaft 31. That is, the cutter disk 8 is ~5 supported at two points, ensuring a stable rotation of the cutter disk 8 when cutting a vegetable.
Note, the lower housing 2, the upper housing 6, the disk 8, the casing 26, the pin 24, the bevel gears 36, 37, the lower engaging portion 33 of the shaft, the handle 10, and the pushdown member 47 are all made of plastic.
Figure 11 to 16 show the construction and operation of the connecting apparatus 7. Referring to Fig. 11, after mounting the lower housing 2 on the fixing appa-ratus 3, and arranging the cutter disk (not shown) inthe lower housing 2, the lower peripheral portion 70 of the upper housing 6 is fitted into the upper peripheral portion 71 of the lower housing 2. Flrst the projection 72 formed on the lower peripheral portion 70 engage with L-shaped slots 73 formed on the upper peripheral portion 71, by moving the upper housing 6 downward along the axis thereofO The L-shaped slot 73 has a substan-tially vertical portion 74 and a substantially horizontal portion 75, and the projection 72 enters the vertical portion first. The upper housing 6 is then slightly rotated about the axis thereof, in relation to the lower housing 2, so that the connecting apparatuses 7 lock both the housings 2 and 6, as described later.
A pair of connecting apparatuses 7 are mounted on the upper housing 6 at opposite sides (see Fig. 2), respectively, and prevent the projections 72 from being dislodged from the L-shaped slots 73. The connecting apparatus 7 has a pawl 80 engagable with the vertical portion 74 of the L-shaped slot 73. The pawl 80 is located in the upper housing 6, and pro~ects therefrom through an opening 81 formed in the lower peripheral portion 70, so that the pawl 80 engages with the vertical portion 74 of the L-shaped slot 73, as shown in Figs. 12 and 13.
The connecting apparatus 7 comprises an inner member 82 arranged on an inner wall of the upper housing 6, an outer member, i.e., a manual lever 83 arranged on an outer wall of the upper housing 6, and a plate-shaped spring 84 inserted between the upper housing 6 and the manual lever 83, as shown in Figs. 14 and 15. While the upper housing 6 is formed with a first hole 85 and a second hole 86 vertically aligned with and spaced downward from the first hole 85, the manual lever 83 has a first connecting rod member 87 and a second connecting rod member 88 extending through the first hole 85 and the second hole 86, respectively.
The first connecting rod member 87 engages with an opening 89 formed in the inner member 82, and the second connecting rod member 88 is fixed to a surface of the 7~2 - 10 ~
inner member 82 by a screw 90, whereby the manual lever 83 and the inner member 82 are interconnected to each other. The inner member 82 and manual lever 83 are pivotally supported on the upper housing 6 with respect to the first connecting rod member 87, and are biased outwardly by the plate spring 84.
The pawl 80 is formed on the inner member 82 as shown in Fig. 16, and is located beneath the second connecting rod member 88. The pawl 80 has an inclined surface 91 directed downward, so that the pawl 80 can slide on an inner surface of the lower housing 2 when the upper housing 6 is fitted in the lower housing 2.
The plate spring 84 is bent into an arc-like shape in a free state, as shown in Fig. 16. The plate spring 84 has, at opposed ends thereof, a first cutaway portion 92 and a second cutaway portion 93, which are engagable with the first connecting rod member 87 and the second connecting rod member 88, respectively. The spring 84 is mounted between the manual lever 83 and the upper housing 6 so that a convex surface of the spring 84 is in contact with the manual lever 83.
To assemble the connecting apparatus 7, first the plate spring 84 is attached to the manual lever 83, and then the lever 83 with the spring 84 attached is mounted on the upper housing 6; the first and second rod members 87, 88 being inserted in the firs-t and second holes 85, 86, respectively. Next~ the opening 89 is engaged with the rod member 87, and an inner periphery of the opening 89 is fitted in a notch 94 of the rod me~ber 87, then the inner member 82 is fixed to the second rod member 88 by the screw 90.
In a non-operative state, the connecting apparatus 7 is biased outward so that a lower end of the manual lever 83 is situated away from the lower peripheral portion of the upper housing 6, and the pawl 80 is projected through the opening 81. The manual lever 83 is longer than the inner member 82, so the pawl 80 is hidden by the lower end of the lever 83 (see Fig. 12).
When the upper housing 6 ls engaged with the lower housing 2, first, the projection 72 is fitted to the vertical portion 74 of the L-shaped slot 73, then the upper housing 6 is rotated until the pawl 80 engages with the horizontal portion 74 of the L-shaped slot 73 and the projection 72 enters the hori20ntal portion 75 of the slot 73. In this state, the pawl 72 prevents the upper housing 6 from rotating relative to the lower housing 2, so that the projection 72 remains engaged with the L-shaped slot 73 to prevent the upper housing 6 from being removed from the lower housing 2.
On the other hand, when the upper housing 6 is disengaged from the lower housing 2, the manual lever 83 is manually pushed toward the upper housing 6, against the spring 84, as shown in Fig. 15. As a result, the pawl 80 is released from the L-shaped slot 73, as shown in Fig. 15, and the upper housing 6 is rotated so that the projection 72 engages with the vertical portion 74 of the L-shaped slot 73. The upper housing 6 is then moved upward while the projection 72 is guided by the vertical portion 74, and the housing 6 is detached from the lower housing 2. Note, a depression 95 may be forme~ at a lower portion of the manual lever 83 to facilitate manual pushing.
While embodiments of the present invention have been described herein with reference to the attached drawings, many modifications and changes may be made by those skilled in this art without departing from the scope of the invention.
