Description

  The present invention relates to an improvement of a counter typified by a cash register counter used in a supermarket and the like, and more particularly, to a lift counter that can easily adjust the height of a top plate.

  Checkout counters used in supermarkets can adjust the height of the top board according to the height of the store clerk in charge of the checkout counter.

  For example, there is one that realizes height adjustment by a mechanism that turns the handle provided on the counter by hand and changes the rotational force of the handle to the lifting operation of the counter top plate.

  Alternatively, the height is adjusted by stepping on the pedal of the hydraulic pump with the foot, raising the top plate by pushing out the hydraulic cylinder, and releasing and lowering the hydraulic pressure of the hydraulic cylinder.

  The cashier counter is generally long, but a device is also devised so that both ends of the cashier are raised and lowered equally (see Patent Document 1).

The cashier counter generally has a small counter 100 on which a register is placed next to it (see FIG. 10), and the height of this small counter can also be adjusted. However, since this small counter is small enough to place a register on it, there is no particular idea of raising and lowering the top, bottom, left and right evenly. The load on the top plate is also determined by the register, and the center of gravity when the register is placed is almost fixed to the center of the top plate, so if the cylinder to be lifted is pushed up near this center, a special structure This is because even if it is not devised, it can be lifted evenly without tilting back and forth and right and left.
Japanese Utility Model Publication No. 5-17984

  When adjusting the height, it is more accurate to judge whether the adjusted height is good or whether it should be raised or lowered a little, using the same standing posture as when working in the cash register.・ Easy to do.

  However, the handle is generally provided in an unobstructed position below the top plate, so you turn the handle while bending down, that is, you adjust the height in a posture different from the standing posture, so the adjusted height is It is difficult to know whether it is good.

  Also, when you step on the hydraulic pump pedal and raise and lower it with the hydraulic cylinder, you have to step on it many times. If you raise it too much, the hydraulic pressure is released and lowered, etc. It ’s cumbersome to step on the pedal and raise it. Further, since the height adjustment is performed in a posture different from the standing posture during the registering work, it is not possible to fully understand whether the adjusted height is appropriate or not.

  Further, when the counter is raised and lowered, the top corner of the top plate must be raised and lowered uniformly with respect to the base, and if it is raised and lowered unevenly, the raising and lowering will be hindered. This is because the top plate is generally structured such that its four corners are guided by rails provided on the support column on the base side, but if it is not lifted evenly, the relationship with the rails will go wrong.

  In addition, there is a need for a small counter on which a register is placed to be used as a drawer space under the top plate or for other things. However, since the front, back, left and right of the top plate are not lifted up and down evenly, it is necessary to make the action point of pushing up such as a hydraulic cylinder close to the center of gravity of the top plate. This device is also provided below the center of the top plate in plan view. For this reason, there is a problem that a space for providing a drawer cannot be secured.

  In view of the above situation, an object of the present invention is to provide a counter that is easy to adjust in height, or that does not take up space for a structure for height adjustment.

  The invention of the lifting counter according to claim 1 of the present application is a base, a table part connected to the base so as to be movable up and down, and interposed between the base and the table part to raise and lower the table part. And an actuator to be operated. A pinion shaft provided with pinions at both ends is installed on one of the base and the table portion, and a rack that meshes with the pinion is installed on the other. .

  According to a second aspect of the present invention, there is provided an elevating counter according to the present invention, a base, a table portion connected to the base so as to be movable up and down, and the table being raised and lowered by being interposed between the base and the table portion. And a counter having an actuator. The connecting portion to be connected and the actuator are provided on one side of the counter.

  Here, an actuator refers to a device that can obtain a force by an electric signal.

  According to the first aspect of the present invention, the height of the counter can be adjusted only by operating the switch of the actuator, so that the height adjustment work in the same posture as the register work is possible, and simple and accurate adjustment is possible. Become.

  According to the second aspect of the present invention, the same effect as in the first aspect can be obtained, and even if the connecting portion is provided on one side surface, it can be moved up and down. When the connecting part is at the center of gravity of the top plate or away from the center of gravity when the register load is applied to this, a rotational moment is applied to the connecting part, and the connecting part slides with a pair of rails etc. In the case where it is realized by, the frictional resistance at the time of sliding becomes large. As a result, it is difficult to move up and down, and it is difficult to lift with conventional handwheels or stepping hydraulic pumps. Since a large force can be realized, it is possible to move up and down smoothly.

  Further, by providing the actuator on one side, a space can be obtained under the top plate, and drawers and other uses can be obtained.

  Next, an embodiment of the present invention will be described with reference to the drawings.

    FIGS. 1 and 2 show an embodiment of the counter according to claim 1 and a perspective view seen from the standing position side of the store clerk. The counter 1 includes a base 10, a table unit 20 that is connected to the base 10 so as to be movable up and down, and an actuator 30 that is interposed between the base 10 and the table unit 20 to raise and lower the table unit 10. have.

  As shown in FIG. 3, the base 10 includes a rectangular bottom frame 12 that forms the bottom portion 11 and a rectangular column frame 13 that is erected on the left and right ends of the bottom frame 12 as main frames. A rack 14 is erected on the inside of the support frame 13.

  The table portion 20 has a top plate 21 and two leg portions 22 arranged on the left and right ends of the top plate 21 so as to sandwich the support frame 13 from the front and the rear, that is, the support frame 13 and the two leg portions. As shown in FIG. 4, 22 is nested. A bearing plate 23 is bridged between the two front and rear legs 22, and a bearing 24 provided on the leg plate 22 supports a pinion 25 and a holding ring 26 described later.

  When the support frame 13 of the base 10 and the leg portion 22 of the table portion 20 are combined in a nested manner, the pinion 25 meshes with the rack 14, and the rack 14 is sandwiched between the pinion 25 and the holding ring 26. It becomes. By pinching with the pinching ring 26, the engagement between the pinion 25 and the rack 14 is ensured.

  The pinions 25 are provided at the left and right ends of the counter 1, but the left and right pinions 25 are connected by a pinion shaft 27 as shown in FIG. 5, and thus rotate in a synchronized manner.

  The support frame 13 is provided with a rail 15 in the up-and-down direction, and a rail 28 that overlaps with the rail 15 is also provided on the table unit 20 side.

  The actuator 30 is configured such that a pipe-shaped operating rod 31 protruding from the body of the actuator 30 is expanded and contracted by an electric signal, and is operated on a pedestal 32 erected from the bottom 11 as shown in FIG. The heel 31 is installed in a standing posture, and the operating heel 31 pushes up the table portion 20 from below.

  The counter 1 constructed in this way, when the clerk stands on the side of the clerk side in the center of the left and right width, even if it is the same standing posture as the cash register work, the right hand can reach without bending down A switch 2 is provided at the position. The switch 2 is provided with a push button type of an ascending switch 2a and a descending switch 2b. While the switch 2 is being pushed, any movement continues, and when the switch 2 is released at the appropriate height, It comes to stop at the height.

  Therefore, when the store clerk takes the cash register work, the finger reaches the switch 2 only by the posture where the hand is naturally hung at the standing position, and the height can be adjusted in the same posture as the cash register work.

  In addition, if the center of gravity of the table unit 20 and the action point of the actuator 30 are separated from each other in the left and right directions, the table unit 20 may not move up and down equally at both ends, and tends to tilt in either the left or right direction. This is because the rising of the right and left leg portions 22 is not uniform. However, pinions 22 meshed with the rack 14 are provided on the left and right sides of the table portion 20, and these left and right pinions 22 are synchronized with each other by the connection of the pinion shafts 27. By the same rotation, the left and right elevation widths are always kept the same, so that they do not tilt.

  FIG. 6 shows a small counter 3 on which a register is placed, and FIG. 7 is a view showing a state in which the cover on the back surface of the small counter 3 is removed. The counter 1 according to the first embodiment is a counter 1 for reading a price tag of a shopping item. The small counter 3 according to the second embodiment has a counter for money in and out next to such a counter for reading. A register is placed.

  That is, it has a base 40, a table part 50 connected to the base 40 so as to be movable up and down, and an actuator 60 that is interposed between the base 40 and the table part 50 to raise and lower the table part 50. ing.

  As shown in FIG. 8, the base 40 has a bottom portion 41 and two support rails 42 made up of square pipes erected from the two rear corners of the bottom portion 41. The rear and left and right side surfaces are covered with a cover 43, and the front is open.

  The table unit 50 includes a top plate 51 on which a register is placed and a two-stage shelf plate 52 provided below the top plate 51, and a drawer 53 is provided below the top plate 51. The back and left and right side surfaces are covered with a cover 54. The table portion 50 is provided with table-side rails 55 having a U-shaped cross section on the left and right sides of the rear, and is superposed so as to cover the column rail 42 on the base 40 side so that it can slide up and down. Yes. The table-side rail 55 and the support rail 42 form a connecting portion A where the table portion 50 is connected to the base 40 so as to be vertically slidable, so that the table can be moved up and down. That is, the connecting part A is provided on the back side as one side. A switch 4 for performing a raising / lowering operation is provided on the front surface of the top plate 51, and an ascending switch 4a and a descending switch 4b are provided in a push button type.

  As shown in FIG. 7, the actuator 60 is installed close to the back side in a posture in which the operating rod 61 is erected on the bottom 41 of the base 40, and the operating rod 61 can push up the table portion 50. Is arranged. That is, the connecting portion A and the actuator 60 are provided on the back side as the same side surface side.

  The support rail 42 and the table side rail 55 are pressed by a pressing portion 56 as shown in FIG. 9 so that the pair of rails 42 and 55 can slide in close contact with each other. The pressing portion 56 is attached to the outside of the table-side rail 55, and a screw member 56b having a resin member 56a having a low frictional resistance attached to the tip presses the other column rail by screw tightening. It is made for superposition | polymerization of 55 to be in the state with higher adhesiveness. This eliminates play such as rattling between the rails 42 and 55.

  This is because the connecting portion A is provided on the back side, so that the connecting portion A is located far away from the center of gravity of the table portion 50, and as a result, the connecting portion A tends to tilt forward of the table portion 50. Because force is applied as a moment, it is a response. In other words, due to the moment, a load perpendicular to the rails 42, 55 is applied to the paired rails 42, 55, and if there is any play in the overlapping of the rails 42, 55, it will hinder sliding. In this respect, if the pressing portion 56 is provided, the rubbing surfaces of the rails 42 and 55 can be brought into close contact with each other, so there is no play. is there.

  However, even if the resistance is suppressed in this way, a certain level of resistance remains, which is a certain degree of resistance that hinders the raising and lowering by the push-up force by human power using a conventional handle or a hydraulic pump. In that respect, in the small counter 3 of the present embodiment, a force stronger than human power can be obtained by the actuator 60. Therefore, the actuator 60 (or its action point) and the connecting portion A are arranged on one side. Even if it is provided in a close-up state, a good lifting operation can be obtained.

  The small counter 3 having the above-described configuration can be adjusted so that the counter 3 can be adjusted to an appropriate height by a store clerk standing with the register placed on the counter and performing a switch operation in the same manner as the cash register operation. it can.

  In addition, since such a small counter 3 is small in size, it has been difficult to incorporate a conventional lifting mechanism such as a handle or a hydraulic pump in terms of space, but such a problem is solved. Although pedals and cylinders are not good in appearance, such troubles in appearance can be avoided. Furthermore, since the actuator 60 is moved to one side, the space under the top plate 51 and the shelf 52 can be used for the shelf and the drawer, and the convenience is improved.
