JP 05-225441 A

  In recent years, social infrastructure development such as barrier-free has been promoted to provide convenience for wheelchair users. Such barrier-free operation is also promoted in stores such as supermarkets and mass retailers.

  However, since the bagging work table that supports the bagging work by the customer is designed with the work of standing up in mind, it is not easy for wheelchair users to use. In this regard, Patent Document 1 discloses a soccer table that can raise and lower the top board, so that the top board can be raised and lowered even in a bagging work table that supports bagging work by a customer. It is assumed that However, in order to make it easy for wheelchair users to use, it is necessary to lower the top plate to a considerable extent, which is not realistic.

  Moreover, since this type of bagging work table is generally designed to allow simultaneous use by a plurality of users, for example, when a wheelchair user lowers the top board, he / she stands at the same time as the wheelchair user. It is expected that it will be difficult for the user who works as it is.

  An object of the present invention is to obtain a bagging work table that can improve bagging workability for wheelchair users.

  The bagging workbench of the present invention has a structure having a mounting surface for placing a shopping basket, and is pivotally attached to the structure so that the front side descends with the rear side as a fulcrum, and the upper surface is described above A mounting table that constitutes a mounting surface; a rotation restricting portion that regulates a rotation range of the mounting table to position the mounting table at a horizontal position and an inclined position; and the mounting table from the inclined position to the horizontal position. A state of supporting the mounting table in the horizontal position, including a return mechanism that applies a biasing force to the front and returns the mounting table to the horizontal position when no load is applied by the shopping basket; and an operation unit. And a latch mechanism that is released in response to an operation of the operation unit.

  According to the present invention, when the mounting table is positioned at the inclined position, the exit of the shopping basket placed on the mounting table can be directed to the user, thereby making it easier for the wheelchair user to pack the bag. be able to.

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

  FIG. 1 is a perspective view of a bagging work table. The bagging work table 101 is configured on the basis of a structure body 104 that supports a top plate 102 with legs 103. The leg portion 103 is formed by a pair of side plates 105 and a back plate 106 that connects these side plates 105. The top plate 102 is formed by four mounting tables 107 and a frame body 108 provided so as to surround these mounting tables 107. Due to such a structure, a space S surrounded by a pair of side plates 105 and a back plate 106 is formed below the top plate 102. The space portion S is set to a size that allows a wheelchair user (not shown) to accommodate the leg portion while riding on the wheelchair.

  The frame body 108 is fixed to and supported by the leg portion 103, and the four mounting tables 107 are rotatably attached to the frame body 108. In other words, the mounting table 107 is a frame body whose rear portion is supported by the support shaft SA1 (see FIGS. 3 and 7 to 11) so that the front portion side of the bagging work table 101, which is the side where the user is located, is lowered. 108 is rotatably attached (see FIG. 6). Such a loading table 107 is formed with a loading surface 107 a for placing a shopping basket 109 (see FIG. 3) on its upper surface, and is slightly larger than the projection surface of the shopping basket 109. And in order to position the shopping basket 109, the protrusion 110 as a protrusion is protrudingly formed in the front part of the mounting surface 107a.

  The mounting surface 107a of the mounting table 107 is provided on the upper surface of the structure, and constitutes a part of the mounting surface on which the shopping basket is placed. The remaining part of the mounting surface is formed by a front upper surface region of the frame body 108. This area is the mounting surface 108a.

  An operation button 111 as an operation unit is provided on the front surface of the frame 108 so as to correspond to each mounting table 107. These operation buttons 111 are used for lowering the front portion of the mounting table 107.

  FIG. 2 is a front view of the work support mark provided on the operation button 111. The front part of the mounting table 107 is lowered for the convenience of use by the wheelchair user. That is, if the front part of the mounting table 107 is lowered and tilted, the outlet of the shopping basket 109 mounted on the mounting table 107 is directed to the user. This posture is a posture where it is very easy for a wheelchair user to take out an item from the shopping basket 109. Thereby, if the front part of the mounting base 107 is lowered, good bagging workability can be provided to the wheelchair user. Under such circumstances, the user who presses the operation button 111 is primarily a wheelchair user.

  Therefore, as shown in FIG. 2, a work support mark 112 representing a wheelchair is drawn on the operation side end of the operation button 111. The wheelchair user will intuitively press the operation button 111 by looking at the work support mark 112.

  However, when the front portion of the mounting table 107 is lowered, it is an event common to not only wheelchair users but also all short users such as children.

  FIG. 3 is a longitudinal sectional view showing a mechanism for incliningly arranging the shopping basket 109 placed on the placing table 107. The frame body 108 is positioned below the mounting table 107 and has a recess 113. The depression 113 is formed by a concave member 114 having an upper surface opening that is fixed to the frame body 108. The concave member 114 regulates the lowermost position of the mounting table 107 whose front portion is lowered. Thereby, the mounting table 107 is positioned between the horizontal position HP shown in FIG. 3 and the inclined position IP (see FIGS. 7 and 8) where the front portion is supported by the bottom of the concave member 114. In this case, the bottom portion of the concave member 114 restricts the rotation range of the mounting table 107 located at the inclined position IP from further rotation. In this sense, the concave member 114 regulates the rotation range of the mounting table 107 and positions the mounting table 107 at the inclined position IP. Therefore, the rotation range of the mounting table 107 is set between the horizontal position HP and the inclined position IP. It constitutes a part of a rotation restricting part that regulates in between.

  As shown in FIG. 3, the bagging work table 101 includes a return mechanism 115 and a latch mechanism 116.

  The return mechanism 115 is a mechanism that applies an urging force from the inclined position IP to the horizontal position HP on the mounting table 107 and returns the mounting table 107 to the horizontal position HP under the condition that no load is applied by the shopping basket 109. Such a return mechanism 115 is mainly composed of a compression coil spring 117. That is, the compression coil spring 117 is positioned in the vicinity of the support shaft SA1 of the mounting table 107, and is disposed in a compressed state between the bottom of the concave member 114 and the mounting table 107. When the shopping basket 109 is placed on the placing table 107, the compression coil spring 117 is set to an extension strength that allows a free fall of the front portion of the placing table 107 even if the shopping basket 109 is empty. Has been. And the extension strength of such a compression coil spring 117 is the condition that when the shopping basket 109 is removed from the mounting table 107 located at the inclined position IP, in other words, the shopping basket 109 is not loaded. It is also set to such an extent that the mounting table 107 is returned to the horizontal position HP.

  The return mechanism 115 having such a structure further includes a damper 118 that cushions the free fall of the mounting table 107 from the horizontal position HP to the inclined position IP. The damper 118 is configured by a gas spring as an example. Such a damper 118 is located between the bottom of the concave member 114 and the mounting table 107 so as to be positioned in the vicinity of the support shaft SA1 of the mounting table 107.

  The latch mechanism 116 includes the operation button 111 and the catcher 119 described above, and causes the mounting table 107 and its peripheral mechanisms to generate a first state, a second state, and a third state. The first state is a state in which the mounting table 107 is supported at the horizontal position HP by the catcher 119. The second state is a state in which the support of the mounting table 107 by the catcher 119 is released in response to the operation of the operation button 111. The third state is a state in which the mounting table 107 that returns by the return mechanism 115 is allowed to pass through the catcher 119.

  FIG. 4 is a vertical side view showing the latch mechanism 116. First, before explaining the latch mechanism 116, the rotation restricting portion will be explained. As described above, the concave member 114 regulates the rotation range of the mounting table 107 and positions the mounting table 107 at the inclined position IP. Therefore, the rotating range of the mounting table 107 is set to the horizontal position HP and the inclined position IP. It constitutes a part of the rotation restricting part that restricts between the two. On the other hand, as a mechanism constituting another part of the rotation restricting unit, that is, a mechanism for restricting the rotation range of the mounting table 107 and positioning the mounting table 107 at the horizontal position HP, the mounting table 107. A pair of stoppers 120 are provided on both sides of the. As shown in FIG. 4, these stoppers 120 are in contact with the frame body 108 and prevent the mounting table 107 from rotating further upward than the horizontal position HP.

  The latch mechanism 116 will be described. The catcher 119 described above forms the main body of the latch mechanism 116. The catcher 119 is pivotally attached to the frame body 108 via the support shaft SA2, and supports the support position SP (see also FIGS. 3, 8, and 10) for supporting the mounting table 107 located at the horizontal position HP. The position is displaced from the support position SP to the retreat position EP (see FIG. 7). That is, the catcher 119 includes the hook portion 121, and is formed so that the lower surface of the front portion of the mounting table 107 can be supported by the hook portion 121 at the support position SP. When the catcher 119 is rotated and positioned at the retracted position EP, the hook portion 121 is retracted from the rotation trajectory of the mounting table 107, and the mounting table 107 can no longer be supported.

  The catcher 119 is normally positioned at the support position SP. This is realized by the tension coil spring 122 as an urging portion. That is, a holding frame 123 for holding the operation button 111 is screwed to the frame body 108, and the tension coil spring 122 is hooked between the holding frame 123 and the catcher 119 in a state where a tensile force can be exerted. Has been passed. The connection position of the tension coil spring 122 with respect to the catcher 119 is an upper position than the support shaft SA2 of the catcher 119. As a result, the upper portion of the catcher 119 is pulled in the forward direction of the bagging work table 101, so that the hook portion 121 is biased in the direction in which it is positioned at the support position SP.

  The latch mechanism 116 includes a first power transmission unit 124 that transmits a movement generated by the operation of the operation button 111 to the catcher 119 as a movement movement of the catcher 119 to the retracted position EP. That is, the operation button 111 is a rod-like member as shown in FIG. 4 and extends to a position where it passes through the frame body 108 and contacts the catcher 119. The contact position is a position between the support shaft SA2 and the position where the tension coil spring 122 is stretched. Inside the frame 108, the holding frame 123 holds the operation button 111. The operation button 111 has a flange 125 positioned slightly on the tip side from the center. The flange 125 is positioned immediately on the back side of the frame body 108. Between the flange 125 and the holding frame 123, a second compression coil spring 126 for inserting the operation button 111 is disposed in a compressed state. Therefore, the operation button 111 accepts the pushing operation of the operation side end portion to which the work support mark 112 is attached, and when the finger is released in the pushed state, the operation button 111 is restored to the original by the extension force of the second compression coil spring 126. Return to position. At this time, as described above, the operation button 111 extends to a position where it comes into contact with the catcher 119. Therefore, when the operation side end is pushed in, the operation button 111 presses the catcher 119. As described above, the pressing position is a position between the support shaft SA2 and the position where the tension coil spring 122 is stretched. Therefore, the catcher 119 pressed at this position rotates around the support shaft SA2 in the clockwise direction in FIG. Thereby, the catcher 119 moves the hook part 121 to the retracted position EP.

  FIG. 5 is a perspective view showing a mounting structure of the operation button 111 constituting the latch mechanism 116. The above-described mounting structure of the operation button 111 can be more easily understood with reference to FIG.

  Reference is again made to FIG. The latch mechanism 116 includes a second power transmission unit 127 that transmits the movement of the mounting table 107 returning toward the horizontal position HP to the catcher 119 as a movement movement of the catcher 119 to the retracted position EP. In other words, the catcher 119 includes the cam surface 128 that displaces the catcher 119 to the retracted position EP in response to the mounting table 107 that returns toward the horizontal position HP. The cam surface 128 is formed to be positioned below the hook portion 121. An arc having a radius at the top of the hook portion 121 with the support shaft SA2 as the center is assumed, and a curved surface that is gentler than the arc is formed. Therefore, when the mounting table 107 returning to the horizontal position HP comes into contact with the cam surface 128, the contact portion of the mounting table 107 advances while sliding on the cam surface 128, and the catcher 119 responds to the support shaft SA2 accordingly. Is rotated in the clockwise direction in FIG. As a result, the catcher 119 retracts the hook portion 121 to the retracted position EP and allows the mounting table 107 to pass.

  In the present embodiment, the cam surface 128 is arcuate, but the cam surface 128 is not necessarily arcuate and may be linear.

  In such a configuration, the bagging work table 101 supports the bagging work of purchased products by a user who is a customer. That is, the user places the shopping basket 109 in which the purchased product is placed on the placing surface 107 a of the placing table 107. Thereby, favorable bagging workability | operativity can be provided to the user who works while standing.

  On the other hand, when the user is a wheelchair user or a short user, the shopping basket 109 placed on the placement surface 107a of the placement table 107 can be tilted in his / her direction to facilitate the removal of the product. . For this purpose, after placing the shopping basket 109 in which the purchased product is placed on the placing surface 107a of the placing table 107, the operation button 111 is pressed. Thereby, the operation button 111 is pushed in, and the tip part presses and rotates the catcher 119. The rotation direction is the clockwise direction in FIG. Accordingly, the catcher 119 is displaced from the support position SP where the hook unit 121 supports the mounting table 107 to the retracted position EP, and releases the support of the mounting table 107 by the hook unit 121. Then, the free end side of the mounting table 107 falls freely.

  FIG. 6 is a perspective view of the bagging work table 101 showing a state in which the shopping basket 109 is inclined. When the free end side of the mounting table 107 falls freely, the mounting table 107 is inclined and positioned at the inclined position IP. Along with this, the shopping basket 109 placed on the placing surface 107a of the placing table 107 is also inclined. As a result, the shopping basket 109 is held in a state as shown in FIG. 6, that is, in a state where the outlet is directed toward the user. Therefore, when it is considered as a wheelchair user or a short user, the shopping basket 109 is tilted in his / her direction, so that the product can be easily taken out. Thereby, favorable bagging workability | operativity can be provided to a wheelchair user or a short user.

  At this time, the mounting surface 108a formed in the front upper surface region of the frame 108 constituting the structure 104 serves as a table for placing a shopping bag into which a product taken out from the shopping basket 109 is placed. That is, the user can open the shopping bag on the placement surface 108a and successively put the products taken out from the shopping basket 109.

  Further, when the free end side of the mounting table 107 falls freely, a damper 118 provided on the bagging work table 101 buffers the free falling of the mounting table 107. Thereby, the mounting table 107 does not suddenly fall freely but falls gently. For this reason, when the operation button 111 is pressed, the state transition of the shopping basket 109 can be made gentle and refined. In particular, for a wheelchair user with a low line-of-sight position, the state transition of the shopping basket 109 is unfolded in front of the eyes, so it becomes a shocking psychology when an abrupt state transition operation is developed. On the other hand, if such a state transition operation is gentle, it is not necessary to give a psychological burden to the wheelchair user. Moreover, the state of the state transition of the sophisticated shopping basket 109 can even give pleasure to those who see it regardless of whether it is a wheelchair user or a non-wheelchair user.

  Further, when the mounting table 107 is positioned at the inclined position IP, the shopping basket 109 tries to slide the mounting table 107. On the other hand, the ridge 110 blocks this, and the shopping basket 109 is securely held in position.

  FIG. 7 is a longitudinal side view showing a state immediately after the operation button 111 is pressed to place the shopping basket 109 placed on the placing table 107 in an inclined manner. The mounting table 107 rotates until its free end reaches the bottom of the concave member 114 and is held at that position. Such a holding position of the mounting table 107 is an inclined position IP. At this time, assuming that the user has not released his / her finger from the operation button 111, the catcher 119 in the latch mechanism 116 is positioned at the retracted position EP.

  FIG. 8 is a vertical cross-sectional side view showing a state in which a finger is released from the operation button 111 after the operation button 111 is pressed to place the shopping basket 109 placed on the placing table 107 in an inclined manner. When the user releases his / her finger from the operation button 111, the catcher 119 in the latch mechanism 116 returns from the retracted position EP (see FIG. 7) to the support position SP. When the finger is released from the operation button 111, as shown in FIG. 4, the second compression coil spring 126 returns the operation button 111 to the initial position, and the catcher 119 is pulled by the tension coil spring 122 accordingly. This is because the hook portion 121 is positioned at the support position SP.

  FIG. 9 is a perspective view of the bagging work table 101 immediately after the inclined shopping basket 109 is removed. Thereafter, for example, the wheelchair user removes the empty shopping basket 109. At this moment, the mounting table 107 is positioned at the inclined position IP.

  FIG. 10 is a vertical cross-sectional view showing a state of one process in which the placing table 107 returns to the original position after the shopping basket 109 arranged at an inclination is removed. On the other hand, for example, when a wheelchair user removes the empty shopping basket 109, the mounting table 107 positioned at the inclined position IP is rotated upward toward the horizontal position HP by the restoring force of the compression coil spring 117. To do. Since the catcher 119 is positioned at the support position SP that interferes with the rotation trajectory of the mounting table 107, the tip of the mounting table 107 that rotates and abuts against the catcher 119.

  FIG. 11 is a longitudinal side view showing a state in which the return operation of the mounting table 107 has further advanced from the state shown in FIG. It is a cam surface 128 formed on the catcher 119 that comes into contact with the tip of the mounting table 107 that rotates upward. When the mounting table 107 returning to the horizontal position HP comes into contact with the cam surface 128, the contact portion of the mounting table 107 advances while sliding on the cam surface 128, and the catcher 119 is centered on the support shaft SA2 accordingly. As shown in FIG. As a result, the catcher 119 retracts the hook portion 121 to the retracted position EP and allows the mounting table 107 to pass. Therefore, the mounting table 107 that rotates upward returns to the support position SP shown in FIGS. 3 and 4.
