Description

  The present invention relates to a work support apparatus that provides a comfortable posture to a worker who works on a work table such as a checkout counter.

  2. Description of the Related Art Conventionally, there is a checkout counter that is installed in a store such as a supermarket and moves a basket in which products are stored in accordance with a checkout operation. When working on a work table such as a checkout counter, an operator may unconsciously seek an easy posture and take a posture leaning on the work table. This is because the worker knows from experience that it is easier to lean on the workbench when scanning the product code.

  Patent Document 1 describes a commodity data reading apparatus that consciously creates a posture leaning on a work table. That is, in the invention described in Patent Document 1, a support portion that supports the vicinity of the worker's abdomen is provided on the casing of the barcode reader. Therefore, according to Patent Document 1, the worker leans on the support portion and deposits his / her body so that he / she can withstand long hours of work while resting his / her body (the upper left column of page 4). 1st to 8th line).

Japanese Patent Application Laid-Open No. 02-91782

  When leaning on the workbench, the body is inevitably supported by the corners of the workbench, and the body is pressed. In the case of the support part as described in Patent Document 1, the support part is formed of a soft material having heat insulating properties, and a curved surface is formed in a contact part with the body (page 3, upper left column, first row to the third page). (3rd line, FIG. 1 and FIG. 2), but it cannot be denied that it still gives the body a feeling of pressure. Moreover, since the support part described in Patent Document 1 supports the vicinity of the abdomen (second page, lower right column, line 18 to page 3, upper left column, first line), the body was deposited in the support part. In some cases, it is expected that the abdomen will feel a pressure, and it remains doubtful how easy it is to provide the operator with a comfortable posture. If the support part cannot provide the worker with a comfortable posture, after all, the work load cannot be reduced.

  Therefore, it is conceivable to provide a comfortable posture to the worker by attaching a supporter that supports the thigh portion of the worker's body with a flexible support surface to the work table. A case where such a support is attached to a checkout counter as a work table will be described with reference to FIG.

  FIG. 11 is a perspective view showing the checkout counter 11. The checkout counter 11 is provided with a stationary barcode scanner 12 at a position opposite to the support 13. Further, the upper surface portion of the checkout counter 11 is a mounting table 15 for a basket 14 in which products are stored. The right mounting table 15 of the barcode scanner 12 is a product introduction unit 15a, and the left mounting table 15 is a product providing unit 15b.

  At the time of check-out, an operator (not shown) takes out the product from the basket 14 of the product introduction unit 15a, and reads the product code by holding the taken-out product in front of the barcode scanner 12. The product from which the product code is read is stored in a separate basket 14 placed in advance on the product providing unit 15b. In this case, the operator can work in a comfortable posture without being pressed against the corner of the checkout counter 11 because the thigh part is supported and lean against the support 13.

  However, as shown in FIG. 11, the upper end 13 d of the support 13 protrudes higher than the front edge 15 d of the mounting table 15. For this reason, depending on the content of the work performed by the checkout counter 11, the support 13 may become an obstacle, and the workability may be reduced.

  An example of the work that reduces workability is the movement work of the basket 14. That is, since the customer takes away the basket 14 in which the product of the product providing unit 15b is stored after the settlement, the worker transfers the basket 14 in the product introduction unit 15a to the product providing unit 15b in preparation for the next checkout. Work to move. In general, an operator rotates the basket 14 by 90 degrees and slides the front of the barcode scanner 12 to move it. However, even with the cage 14 rotated 90 degrees, the upper end portion 13d of the support 13 becomes an obstacle, and it is difficult to pass in front of the barcode scanner 12, or it cannot be passed through at all. In this case, the operator lifts and moves the basket 14, and the work load increases.

  In addition, providing the support 13 at a position away from the checkout counter 11 solves the above-described problem. However, the distance between the worker leaning on the support 13 and the checkout counter 11 is increased, which is inconvenient.

  An object of the present invention is to provide a comfortable posture for a worker who performs work on a work table without deteriorating workability of work such as moving a car.

The work support device according to the present invention supports a work table and a body that supports the body in a posture leaning against the work table at a close position where the upper end portion protrudes higher than the front edge of the upper surface of the work table. A tool and the support are positioned at the proximity position and a separation position that is farther away from the front edge of the work table than the proximity position, and the body in the leaning posture receives a force pressing the support surface. A work support apparatus comprising: a holding mechanism that enables the support to be moved from the separation position to the proximity position, and allows the support to be moved from the proximity position to the separation position by its own weight .

  According to the present invention, since the thigh portion of the body leaning on the support surface of the supporter is supported without being pressed, an easy posture can be provided to the operator. In addition, since the supporter moves away from the front edge of the workbench simply by moving the body away from the supporter, the workability is reduced even for work where the presence of the supporter is an obstacle, such as moving the basket on the workbench. Can be done without.

  An embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a front view showing an application example to a checkout counter as an embodiment of the work support apparatus of the present invention. In the present embodiment, a checkout counter 101 is provided as a workbench, which is installed in a store such as a supermarket and moves a basket 104 in which products are stored in accordance with a checkout operation. The checkout counter 101 is provided with a stationary barcode scanner 102 in front of it. FIG. 1 is a front view seen from an operator 301 (see FIG. 2) who operates the barcode scanner 102.

  An upper surface portion of the checkout counter 101 is a product mounting table 103. In FIG. 1, the right-side mounting table 103 of the barcode scanner 102 is a product introduction unit 103a, and the left-side mounting table 103 is a product providing unit 103b.

  A support 201 is attached to the checkout counter 101 at a position opposite to the barcode scanner 102 and facing the worker 301.

  At the time of check-out, the worker 301 who is a store clerk takes out a product from the basket 104 placed on the product introduction unit 103a by a customer (not shown), and reads the product code by holding the taken product in front of the barcode scanner 102. And the product whose product code is read is stored in another basket 104 previously placed on the product providing unit 103b. Then, when the reading of the product codes of all the products is completed, the payment is made at a payment terminal (not shown) (for example, a POS terminal). After the settlement, the customer takes away the basket 104 of the product providing unit 103b in which the product is stored to a bagging stand (not shown).

  After the check-out, the worker 301 stores the product read from the product code at the next check-out, and transfers the empty basket 104 of the product introduction unit 103a to the product providing unit 103b. Move.

  FIG. 2 is a side view of the checkout counter 101 showing a state in which the worker 301 is reading the product code. Referring to FIG. 2, the usage of the support 201 can be understood.

  The worker 301 takes out a product from the basket 104 placed on the product introduction unit 103a, holds the taken product in front of the barcode scanner 102, reads the product code, and reads the product code read from the product provision unit in advance. When housed in another basket 104 placed on 103 b, the body 302 is deposited on the support 201. That is, it leans on the support 201. It is the thigh region 303 that leans on. And the support tool 201 supports the body 302 with the support surface 201a formed in the operator 301 side who performs operation.

  At this time, as shown in FIG. 2, the support 201 is at a position where the upper end portion 201 d protrudes higher than the front edge portion 103 d of the mounting table 103 which is the upper surface portion of the checkout counter 101 (hereinafter referred to as a proximity position). The body 302 is supported by the support surface 201a. Here, the front edge portion 103 d is a portion on the support 201 side of the mounting table 103 in FIG. 2, and in the checkout counter 101 of the present embodiment, it is closer to the support 201 than the front panel 105. It is a protruding part.

  The support 201 is positioned at a proximity position where the body 302 is supported by the support surface 201a shown in FIG. 2 and a position (hereinafter referred to as a separation position) that is farther from the front edge portion 103d than the proximity position. Yes. Further, the support 201 moves from the separation position to the proximity position when the thigh region 303 of the body 302 in a posture leaning against the checkout counter 101 receives a force pressing the support surface 201a. It is a holding mechanism 401 (501, 601) described later that enables such movement.

  When the worker 301 performs the above work, a step 251 may be provided in the vicinity of the checkout counter 101 as shown in FIG. The step 251 has a mountain shape with a raised central portion, and a front slope 252 gently descending from the central portion toward the checkout counter 101 and gently from the central portion toward the opposite side of the checkout counter 101. And a slope 253 after descending. The front slope 252 naturally tilts the posture of the worker 301 when the worker 301 gets on, and naturally maintains the posture leaning on the support 201. Moreover, since the posture of the worker 301 is naturally tilted forward as another role, the worker 301 is psychologically invited to use the supporter 201. The rear slope 253 smoothly guides the backward movement of the worker 301, and plays a role of avoiding stepping off the step 251 and scrambling or overturning with the backward movement.

  The first embodiment of the present invention will be described below with reference to FIGS.

  FIG. 3A is a side view showing a state in which the support 201 according to the first embodiment is in the proximity position, and FIG. 3B is a side view showing the holding mechanism 401 in that state in an enlarged manner. is there.

  FIG. 4A is a side view showing a state in which the support 201 according to the first embodiment is in the separated position, and FIG. 4B is a side view showing the holding mechanism 401 in that state in an enlarged manner. is there.

  First, the lifting mechanism 202 will be described. The support 201 can be moved up and down as viewed in FIG. The lifting mechanism 202 enables the support 201 to be lifted and lowered.

  As shown in FIG. 3A and FIG. 4A, the support 201 is composed mainly of a gas spring 203. That is, a housing 204 for the lifting mechanism 202 is provided, and a gas spring 203 is provided vertically in the housing 204. The gas spring 203 has a structure in which oil and high-pressure gas are sealed in the cylinder tube 205 and the piston rod 206 protruding from one end is extended and compressed. The extension speed and compression speed of the piston rod 206 depend on the diameter and number of orifices formed in a piston body (not shown) connected to the piston rod 206 and provided inside the cylinder tube 205. Such a gas spring 203 generates a load by pushing the piston rod 206. In this embodiment, the push spring type is used as the gas spring 203. The push lock type gas spring 203 has a valve for controlling the opening and closing of the orifice described above in a piston body (not shown) provided in the cylinder tube 205, and the piston rod 206 is moved to an arbitrary position by opening and closing the valve. Can be stopped. Such opening and closing of the valve is performed by rotating an operation lever 207 (see FIG. 1) provided in the housing 204 in the vertical direction. As an example, the valve is configured to open the orifice according to the upward rotation of the operation lever 207, and the valve is closed according to the downward rotation of the operation lever 207.

  By providing such an elevating mechanism 202, the worker 301 can raise and lower the support 201 and adjust the position of the support 201 to the optimal position for his / her body 302. At that time, when the operation lever 207 is rotated upward, the orifice is opened, and the piston rod 206 can be moved up and down. Therefore, the worker 301 aligns the support 201 at the optimum position, and then rotates the operation lever 207 downward. As a result, the orifice is closed, the piston rod 206 is held in that position, and the vertical position of the support 201 is set.

  The support 201 is attached to the front panel 105 (see FIG. 1) of the checkout counter 101 through the base 208 of the elevating mechanism 202 via the connection fixing part 212. However, the checkout counter 101 includes a strong frame structure (not shown) on the back side of the front panel 105, and the support fixture 201 is attached to the checkout counter 101 by fixing the connection fixing portion 212 to the frame structure. It is attached.

  Next, the support 201 will be described.

  As shown in FIG. 3A and FIG. 4A, the support 201 has a base 208 formed of a hard member, and a flexible cushion 209 is fixed to the base 208. Yes. As a material of the base 208, for example, metal, resin, wood, or the like can be used. The cushion 209 is a flexible member formed using a resin foaming technique, and is fixed to the base 208 by being molded together with the base 208 as an example. The support 201 having such a structure may be covered with a cover (not shown) as necessary.

  The support 201 is configured to support the thigh region 303 of the body 302 of the worker 301 in a posture leaning against the checkout counter 101 with the support surface 201a. In this case, the support surface 201a that supports the portion 303 is formed to be wide to some extent, and it is desirable to ensure 120 mm or more in the vertical direction.

  Further, the support 201 has a curved shape in which an upper end portion facing the body 302 is curved toward the checkout counter 101. Thereby, the support tool 201 forms the curved part 201b in the curved part, and the operator 301 leaning against the support tool 201 is weakened in pressure on the abdomen.

  The base portion 208 has a flange portion 210 communicating with the back surface at the lower center portion of the base portion 208, and a mounting hole 211 is linearly formed in the flange portion 210. The support 201 is fixed to the lifting mechanism 202 by press-fitting the piston rod 206 into the mounting hole 211. Note that the turning portion 210 is formed in a shape and a size so that the base portion 208 does not interfere with the components of the lifting mechanism 202 during the lifting and lowering operation of the support 201.

  Next, the holding mechanism 401 will be described. Here, in the present embodiment, the support 201 is such that the support surface 201a is substantially vertical at the close position (see FIG. 3), and at the separation position, the support surface 201a is separated from the checkout counter 101. It is inclined (see FIG. 4).

  The holding mechanism 401 of this embodiment includes a rotation mechanism 411. That is, as shown in FIGS. 3 and 4, the piston rod 206 includes a lower piston rod 421 that protrudes from the gas spring 203 and an upper piston rod 422 that is press-fitted into the mounting hole 211. The upper piston rod 422 is pivotally attached to the lower piston rod 421 by a pivot shaft 412 as a pivot center of the lower portion of the support 201. The lower piston rod 421, the upper piston rod 422, and the rotation shaft 412 constitute a rotation mechanism 411. The support 201 is rotatable about a rotation shaft 412 by a rotation mechanism 411.

  A protruding piece 413 protruding in the axial direction is provided at the end of the upper piston rod 422 on the rotating shaft 412 side at a position opposite to the cushion 209 (on the checkout counter 101 side). The protruding piece 413 comes into contact with the first contact portion 414 that is the portion of the lower piston rod 421 opposite to the cushion 209. The first contact portion 414 is provided with an arc portion 416 along the locus of the tip of the protruding piece 413 that rotates so as to rise about the rotation shaft 412, and is integrally provided with the lower piston rod 421. A second contact portion 415 that is bent toward the cushion 209 and comes into contact with the protruding piece 413 is provided integrally with the arc portion 416 at the end of the arc portion 416. The protruding piece 413, the first contact portion 414, and the second contact portion 415 also constitute the holding mechanism 401.

  Since the protruding piece 413 is in contact with the first contact portion 414 or the second contact portion 415, the rotation is restricted, and the upper piston rod 422 is only allowed to rotate within a predetermined angle. That is, when the protruding piece 413 comes into contact with the first contact portion 414, the support member 201 is positioned in the proximity position (see FIG. 3), and the protruding piece 413 comes into contact with the second contact portion 415. When it does, it will be in the state located in the separation position (refer FIG. 4). As described above, the support 201 is tilted in the direction in which the support surface 201a is substantially vertical at the close position and the support surface 201a is separated from the checkout counter 101 at the separation position, with the rotation shaft 412 as the center. It is possible to move.

  And by such a holding mechanism 401, the support tool 201 can be moved from the separation position (see FIG. 4) to the close position (see FIG. 3) by receiving the force with which the body 302 presses the support surface 201a. It has become. The support 201 is positioned in the proximity position as long as the body 302 receives a pressing force, and the support 201 is positioned in the proximity position and supports the body 302.

  Next, the force applying mechanism 451 will be described. The force imparting mechanism 451 imparts force to the support member 201 from the proximity position to the separation position.

  As shown in FIGS. 3B and 4B, the first contact portion 414 of the lower piston rod 421 has a recess 452 at a position where the protruding piece 413 comes into contact with and covers the first contact portion 414. Further, a compression spring 453 is provided in the concave portion 452 as a first pressing member constituting the force applying mechanism 451 so as to press the protruding piece 413 in the direction of the second contact portion 415 by its elastic force.

  The force of the compression spring 453 is weaker than the force with which the thigh region 303 of the body 302 in a posture leaning against the checkout counter 101 presses the support surface 201a. Therefore, when the body 302 receives a force pressing the support surface 201a, the compression spring 453 compresses, and the support member 201 positioned at the separation position moves toward the proximity position. When the body 302 in a leaning posture moves away from the support surface 201a and there is no force to press the support surface 201a, the compression spring 453 in the compressed state is restored and extended, and receives the pressure by the body 302 to the proximity position. The positioned support 201 is moved toward the separation position so that the support surface 201a is inclined in a direction away from the checkout counter 101.

  FIG. 5 is a plan view showing the checkout counter 101. As described with reference to FIG. 1, after checkout, the worker 301 (see FIG. 2) transfers the basket 104 placed on the product introduction unit 103 a to the product providing unit 103 b in preparation for the next checkout. It is necessary to move so that the arrow in FIG. At this time, the worker 301 wants to move the basket 104 of the product introduction unit 103a by 90 degrees and slide it in front of the barcode scanner 102 to the product providing unit 103b.

  Therefore, the worker 301 separates the body 302 (see FIG. 2) in a posture leaning against the checkout counter 101 from the support surface 201 a of the support 201. Then, the force with which the body 302 presses the support surface 201a disappears, and the support 201 moves from the proximity position indicated by the dotted line in FIG. 5 to the separation position indicated by the solid line in FIG.

  When the support 201 is positioned at the separation position indicated by the solid line in FIG. 5, the distance between the upper end portion 201d and the front edge portion 103d is greater than the proximity position indicated by the dotted line in FIG. The cage 104 rotated by a certain degree can be easily moved from the product introduction unit 103a to the product provision unit 103b by sliding in front of the barcode scanner 102 without contacting the support 201.

  Note that the worker 301 does not have to get off the step 251 (see FIG. 2) when separating the body 302 from the support surface 201a of the support 201, and raises the body 302 on the front slope 252 or the step 251. What is necessary is just to retreat in the direction of the center part.

  Next, a second embodiment of the present invention will be described with reference to FIGS. 6 and 7 shown below.

  FIG. 6A is a side view showing a state where the support 201 according to the second embodiment is in the proximity position, and FIG. 6B is a side view showing the holding mechanism 501 in an enlarged state. is there.

  Fig.7 (a) is a side view which shows the state which has the support tool 201 which concerns on 2nd Embodiment in a separation position, FIG.7 (b) is a side view which expands and shows the holding mechanism 501 of the state. is there.

  Note that parts having the same functions as those shown in FIGS. 1 to 5 are denoted by the same reference numerals, and description thereof will be omitted (hereinafter the same).

  Unlike the first embodiment of the present invention, the second embodiment of the present invention is not provided with the force applying mechanism 451 (compression spring 453), and the support 201 is inclined by its own weight and moved to the separated position. Move towards. Therefore, the holding mechanism 501 of this embodiment holds and supports the support 201 at a position where the center of gravity of the support 201 is close to the checkout counter 101 (the worker 301 side) with respect to the rotation shaft 412. The tool 201 is moved from the proximity position to the separation position by its own weight.

  The holding mechanism 501 of the second embodiment includes a rotating mechanism 511, which, like the rotating mechanism 411 of the first embodiment, has a lower piston rod 521, an upper piston rod 522, The rotating shaft 512, the protruding piece 513, the first contact portion 514, the second contact portion 515, the arc portion 516, and the like are included. At this time, the upper piston rod 522 of the present embodiment is longer than the upper piston rod 422 of the first embodiment, and the long portion on the side that is press-fitted into the mounting hole 211 of the base 208 is It is bent twice at a right angle so as to be in a more forward position (operator 301 side) in a state parallel to each other with respect to the long portion that is rotatably attached to the lower piston rod 521.

  The support 201 is held by the upper piston rod 522 having such a shape at a position where the center of gravity is close to the rotation shaft 412 on the side opposite to the checkout counter 101 (the worker 301 side). . Therefore, the support 201 tends to move from its proximity position (see FIG. 6) to the separation position (see FIG. 7) by its own weight (including the weight of the base 208 and the cushion 209).

  In other words, when the thigh portion 303 of the body 302 in a leaning posture is not pressing the support surface 201a, the support 201 of the present embodiment is inclined in the direction of the separation position about the rotation shaft 412 by its own weight. Thus, it is positioned at the separation position (see FIG. 7). Then, when the body 302 in a leaning posture receives a force pressing the support surface 201a, the body 302 moves from the separation position to the proximity position (see FIG. 6).

  Also in the present embodiment, when the support 201 is positioned at the separation position, the distance between the upper end portion 201d and the front edge portion 103d is longer than the proximity position, so the basket 104 and the support 201 are not brought into contact with each other. In addition, the basket 104 can be easily moved from the product introduction unit 103a to the product provision unit 103b by sliding in front of the barcode scanner 102.

  Next, a third embodiment of the present invention will be described with reference to FIGS.

  FIG. 8 is a side view showing a state in which the support 201 according to the third embodiment is in the proximity position.

  FIG. 9 is a side view showing a state in which the support 201 according to the third embodiment is in the separation position.

  FIG. 10 is a perspective view showing a support 201 according to the third embodiment.

  The holding mechanism 601 according to the third embodiment of the present invention is greatly different from the above-described embodiment. Moreover, in the separation position (refer FIG. 9) of 3rd Embodiment, the support tool 201 is separated in the horizontal direction from the checkout counter 101 rather than the proximity position.

  That is, in the present embodiment, the front panel 105 to which the housing 204 is fixed via the connection fixing portion 212 is an independent front panel 105a that is independent from other parts of the front panel 105, and this independent front panel 105a. Is fixed to the drawer portion 611. The drawer 611 is held by a pair of slide rails 612 as a slide mechanism provided in the holding mechanism 601 of the present embodiment provided on both sides of the checkout counter 101 (see FIGS. 1 and 2). As shown by the arrows in FIG. 10, the sliding movement can be smoothly performed in the drawing / storage direction.

  At this time, a fixed plate 613 (described later) is provided on the back side (the storage direction side) of the drawer portion 611 so that the drawer portion 611 cannot move to the back side of the fixed plate 613. The slide rail 612 is provided with a stopper (not shown), and movement of the drawer portion 611 in the drawer direction is restricted. In other words, the drawer 611 is allowed to move only within a predetermined range. That is, the support 201 is in a state of being positioned at a close position (see FIG. 8) when the drawer portion 611 approaches the fixed plate 613 and the movement is restricted, and the movement of the drawer portion 611 is restricted by the stopper. When it is done, it will be in the state located in the separation position (refer FIG. 9). That is, the holding mechanism 601 according to the present embodiment includes the drawer portion 611, the slide rail 612, the fixed plate 613, and the like. Since the holding mechanism 601 includes the slide rail 612, the support 201 can be moved between the proximity position and the separation position so that the support member 201 is separated from the checkout counter 101 in the horizontal direction at the separation position. It has become.

  The support 201 can be moved from the separation position (see FIG. 9) to the close position (see FIG. 8) when the body 302 in a leaning posture receives a force pressing the support surface 201a. .

  Further, a compression spring 652 as a second pressing member is provided with one end thereof fixed to a fixing plate 613 inside the checkout counter 101. The compression spring 652 elastically presses the drawing portion 611 in the drawing direction, and the pressing force is weaker than the force with which the body 302 in a leaning posture presses the support surface 201a.

  Therefore, in a state where the support surface 201a is pressed by the operator 301 leaning on, the compression spring 652 is compressed, the drawer portion 611 is accommodated, and the support 201 is positioned in the proximity position (see FIG. 8). . On the other hand, in a state where the operator 301 is not leaning and the support surface 201a is not pressed, the compression spring 652 presses the pull-out portion 611 in the pull-out direction, and the support 201 moves toward the separation position (see FIG. 9). To do. That is, the force applying mechanism 651 of the present embodiment includes a compression spring 652, a fixed plate 613, a drawer portion 611, and the like.

  Also in this embodiment, when the support 201 is positioned at the separation position (see FIG. 9), it is farther from the front edge portion 103d of the checkout counter 101 than the proximity position (see FIG. 8). The distance between the upper end portion 201d and the front edge portion 103d is farther. Accordingly, the basket 104 can be easily moved from the product introduction unit 103a to the product providing unit 103b by sliding in front of the barcode scanner 102 without bringing the basket 104 and the support 201 into contact with each other.

  As described above, in any of the embodiments, the support surface 201a of the supporter 201 supports the thigh portion 303 of the body 302 in a posture leaning against the checkout counter 101 without squeezing, and is easy for the operator 301. A posture can be provided. Moreover, since the support 201 is separated from the front edge portion 103d of the checkout counter 101 only by separating the leaning body 302 from the support 201, the presence of the support 201 such as the movement of the basket 104 is an obstacle. Can be performed without deteriorating workability.
