Description

  The present invention relates to a product advance display device that functions to push out displayed products from the rear to the front and pushes out the remaining products from the rear each time the product is taken out.

  Various structures have been disclosed as an apparatus for extruding display goods. For example, in the past, as shown in Patent Document 1 and Patent Document 2, a movable part that presses a product from behind is provided, and this movable part is urged by an elastic body. The example which made it easy to take out the tip commodity by protruding is shown.

  Further, in recent years, the present applicant has developed a structure shown in Japanese Patent No. 4395843, which is Patent Document 3, and in these documents, a rail portion and a push plate that slidably engages with the rail portion. And a spring that urges the push plate toward one end of the rail portion, and a basic structure for pushing the product forward by a push plate pressed forward by the spring is disclosed.

Shokai 55-89370 Japanese Utility Model 5-53566 Patent No. 4,395,843

  The push plate used in Patent Document 3 is currently on the market, and the relationship between the push plate and the rail will be described later with reference to FIG. Due to the increase in resistance that occurs at the time of (pushback direction), there are drawbacks from the user such as “hook” and “bad movement”.

  More specifically, referring to FIG. 9, a plurality of products are sequentially arranged in a product display case 60 and pressed by a push plate 61 to urge the product in the forward direction. If the goods are taken out sequentially from the front, the goods become less in the goods case and must be replenished.

The product is replenished by pinching the push plate 61 with fingers and pushing it back. Considering the expiry date of the product and keeping the “first-in first-out concept”, a new supplementary product must be placed between the product already installed and the push plate 61. The replenishment operation is performed while the push plate 61 is pushed back to the temporary stopper 63 provided in the vicinity of the retracted end of the case 60 and temporarily fixed. The same applies when a new product is installed.
Note that “first-in first-out” is an industry term that means selling in order from old products that were put in first on the time axis. As a synonym, there is also the term “in-depth out” as seen from the physical position dimension axis.

When pushing back the push plate, as described above, the upper end of the push plate is pushed or pinched with a finger. In the case of an existing push plate, there is a finger hook, but this part is explained and used. The reality is that it is not thorough. Look at the attitude of the push plate 61 at this time from the side and go moved while "upward fallen to the rear". Therefore, the contact point between the sliding portion 64 of the push plate 61 and the rail portion 65 on the case side is mainly the lower end portion 67 of the front end and the upper end portion 68 of the rear end on the push plate side. In particular, the upper end portion 68 at the rear end is acted upon by a force in the direction of biting into the rail portion 65, resulting in a large sliding resistance. Problems such as “getting caught” and “poor movement” from the user are reported.

  The above-mentioned problems of “hooking” and “poor movement” appear more conspicuously when the length of the pressing plate is higher when the length of the pressing plate is constant. Conversely, when the longitudinal length is sufficiently long relative to the height, the operation is smooth.

  In addition, it is actually difficult to sufficiently lengthen the longitudinal length of the push plate due to dimensional restrictions. In the case of an actual case, there are a shelf size and a case size for installing the case. On the other hand, I want to keep as many products as possible in a case. However, when the length of the push plate is increased, the volume is increased, and not only the cost is increased, but also the number of the mounted plates is decreased by 1 even when the length is increased by 3 mm, for example. Therefore, even if the length of the push plate is not necessary and sufficient, it has been compromised even if there is a problem when the push plate is returned.

Also, on the case side, there must be a “stepped portion of the temporary stopper” that has the function of temporarily fixing the push plate near the retracted end, and a portion where the thickness of the bottom plate is reduced must be provided. It was easy to cause damage when the strength of the surroundings decreased and handling was difficult.
When this “temporary stopper” is used, the push plate is temporarily fixed in a state in which a spring force for advancement is applied. However, since the temporary fixing is performed with a slight overlap of the areas, it is likely to become unstable due to a slight external force or aged wear. As a result, it may come off unexpectedly, causing the push plate to run away, resulting in damage to the case, spring, or injury to the operator's fingers.

  Furthermore, when the pressing plate is temporarily fixed to the temporary stopper, a thin metal band spring (Conston, trademark of the applicant) is stretched all over the longitudinal direction of the case until the product is replenished. Looks like a place to be touched. For this reason, a thin metal band is generally seen like a knife or other blade, and is actually considered dangerous even if there is no danger.

  The spring used always has a life due to metal fatigue. When the spring breaks due to this metal fatigue, it is a metal band, so that it is quickly wound up with a large momentum on the side that is fixed with a broken and broken fracture surface. In particular, it is very dangerous to break when the pressing plate is temporarily fixed to the temporary stopper, and if it comes in contact with the operator, it may lead to injury or accident.

As a countermeasure against this, a structure in which a cover 70 is attached on a spring 69 has been devised as shown in FIGS. That is, a soft resin tape that is moved in conjunction with the push plate 61 is used, and the spring 69 is covered so that the spring 69 cannot be touched not only by visual observation but also the safety is improved.
In FIG. 10, the soft resin tape is a part, and in FIG. 11, the soft resin tape is an endless belt, and the rear rail portion 65 is also covered. Note that these covers 70 have a known structure in which pulleys 72 and 73 are used, and the surface of the cover 70 is displayed with a remaining amount (remaining number) of mounted products.

  However, the provision of the cover 70 improves safety. However, the cover 70 is complicated and the cost is increased. Therefore, the spring 69 remains visible when the product is replenished without entering the market. Used and remained dangerous.

  In recent years, there has been disclosed a device in which a push plate of a push plate shown in Utility Model Registration No. 313481 is extended upward and tilted backward, and a new product is inserted therefrom. However, if you try to insert a new product, it is difficult to insert the push plate smoothly because it is difficult to retreat, and if you try to push it further, there is no escape of power, it will overwhelm the existing product line and it will fall forward, It was also the cause of falling back and hurting.

  As described above, in the commodity advance display device, the push-back operation of the push plate is not particularly smooth, and therefore, the “first-in first-out operation” at the time of replenishing the commodity is rarely performed thoroughly.

  For this reason, this invention makes it easy to push the push plate back smoothly when refilling the product, etc., and the product to be replenished is brought into contact with the push plate and the push plate is retracted It is to be able to replenish. This is to ensure that the “first-in first-out operation” is performed thoroughly.

In order to achieve the above object, a commodity advance display device according to the present invention includes a rail portion formed of an opening formed on a bottom surface of a case along a product pushing direction, and slidably engaged with the rail portion. comprising a push plate having a pair of rails sliding portion which, a spring for biasing the push plate to the extrusion direction of the product along said rail section, in the said press plate, yet lower its rear side The wheel is attached to the push plate so that the lower end of the wheel is in contact with the upper surface of the rail portion at the outer periphery, and the wheel is provided with play in the fitting groove of the push plate. It is attached (Claim 1).

According to this, when the push plate is pushed back backward by the wheel at the lower end on the back side of the push plate, the wheel rotates in contact with the upper surface of the rail portion, so that it can be smoothly moved from the reduction of the frictional resistance. it can. In particular, since the wheel is attached with play in the fitting groove of the push plate, the rearward movement is smooth . Moreover, there is no need to increase the longitudinal length of the push plate. When pushing back to the rear of the push plate, even if the upper end of the push plate is pushed back, it is smoothly moved without astringency.

The product advance display device according to the present invention is slidably engaged with a rail portion formed of an opening formed on the bottom surface of the case along the direction of pushing out the product, and two cases facing the rail portion. A push plate having a pair of rail sliding portions, and a spring for urging the push plate in the pushing direction of the product along the rail portion. The wheel is attached to the push plate so that a gap is provided between the lower end side and the upper surface of the rail portion on the outer periphery, and the push plate is pushed back when the push plate is pushed back. The plate is inclined rearward so as to come into contact with the upper surface of the rail portion (Claim 2).

According to this, there is a gap between the push plate and the rail portion, and when a backward pushing force is applied, the push plate falls backward, but the wheel contacts the rail portion for the first time, and the wheel rotates. The push plate is smoothly moved backward. The lower end of the outer circumference of the wheel is slightly higher than the sliding part of the push plate in the vertical direction. Therefore, when pushing forward of the push plate, the push plate is displaced by a spring almost at right angles to the rail part. Therefore, the wheel does not conflict with the rail portion and does not increase the sliding resistance.

One or more wheels are preferably provided (claim 3 ). That is, in the embodiment, two are provided, but the number is not limited and one may be used. The diameter of the wheel on the example was about 4 mm to 15 mm, and in the experimental results, the larger diameter showed smooth rotation. Furthermore, when there are a plurality of wheels, the left and right wheels may be independent or connected by a connecting shaft.

Wheel, the fitting grooves of the formed press board is preferably provided is fitted wheel axle (claim 4). According to this, formation of the attachment site | part to the pushing plate of a wheel becomes easy.

Press plate, preferably has a sloping portion the upper portion than the vertical middle is inclined rearward (claim 5). Thereby, goods can be replenished between the goods in the back and the push plate. That is, by pressing the product to be replenished against the inclined portion of the push plate, a backward force is applied to the push plate, the push plate rotates the wheel and smoothly moves backward, and the product is replenished. Smooth.

  This means that when replenishing the product, the spring is not exposed, the spring that seems to be dangerous at first glance is not seen, and damage caused by direct contact is reduced. By covering the spring with the product, even if a breakage accident occurred, the danger to the worker directly decreased.

The inclined portion of the push plate, the other part having a fixing surface and the inclined surface may be constituted by mounting on the press plate (claim 6). Thereby, it can attach to a push board later. A protrusion or the like is formed on the fixing surface and can be attached by being inserted into a hole formed in the push plate, or can be attached later using a double-sided tape or the like.

  As described above, according to the configuration of the first aspect, the wheel rotates on the rail portion when the push plate is pushed back, so that the sliding resistance is reduced and the push plate can be smoothly moved backward. Even if the vicinity of the upper end of the push plate is pushed, it can be pushed back smoothly without being caught. It is no longer necessary to provide a dedicated finger hook for the push plate on the market. Since the push-back to the rear of the push plate becomes smooth, the upper end of the push plate can be extended upward.

Further , when the push plate is pushed back to the rear piece, the wheel rotates on the rail portion, and the push plate can be smoothly moved backward on the rail portion. In particular, since the wheel is mounted with play in the fitting groove of the push plate, a necessary and sufficient effect can be obtained for backward movement.

According to the configuration of claim 2 , during the push back operation of the push plate, the push plate falls backward from the gap between the push plate and the rail portion, so that the wheel comes into contact with the rail portion, The wheel rotates and the push plate can be smoothly moved on the rail portion. When the push plate is pressed forward, the push plate is displaced by the spring at a right angle to the rail portion, so that the wheel floats from the rail portion and does not increase the sliding resistance.

According to the configuration of the third aspect, the number of wheels may be one or two, and can be appropriately determined according to the design conditions.

According to the configuration of the fourth aspect , the wheel of the push plate may be attached by a simple configuration in which the wheel axle is fitted in the fitting groove formed in the push plate.

According to the structure of Claim 5 , since it has an inclined surface in the upper part of a push plate, replenishment of goods is enabled using this inclined surface. Assuming that the return operation is smooth, it is necessary to use a push plate having an inclined surface, since the wheels are provided as in the present invention, and the backward movement is smooth. In other words, the use of the push plate having the inclined surface makes it easy to replenish products. As a result, the replenishment product can always be put in the deepest part of the installed product, and the execution of the “first-in first-out operation” of the product can be ensured.
Moreover, when replenishing the product, the state covered with the existing product can be maintained without exposing the Conston spring. As a result, it is possible to improve the safety of appearance without increasing the number of parts, and to reduce the failure of carelessly touching the Conston spring and causing damage.

According to the configuration of the sixth aspect, another article can be easily attached to the conventional push plate and changed to a push plate having an inclined surface, and a “first-in first-out operation” of the product can be performed when the product is replenished. It became.

The wheel according to claim 1, wherein when the push plate is pushed back, the wheel is attached to the push plate so that the push plate is inclined and contacts the upper surface of the rail portion. Product advance display equipment. It is explanatory drawing which attached to the front and back both surfaces of the spring in the other product advance display apparatus of a prior art example.

  Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a product advance display device 1 according to this embodiment, and this product advance display device 1 includes a case 2 and an advance device 3. The case 2 is a rectangular member made of, for example, a transparent resin material, and stores an arbitrary product 4 such as tobacco. The advancing fixtures 3 are slidably disposed on the bottom surface of the case 2, and performs the function of pushing out the goods 4 forward.

  The case 2 is formed in an appropriate size according to the shape and storage amount of the product 4, and has an upper surface opened and a rail portion 5 and a spring fixing portion 7 formed on the bottom surface. The rail portion 5 is a groove-shaped opening formed in the longitudinal direction, that is, in the arrangement direction of the products, in the substantially central portion of the bottom surface of the case 2, and slides on the push plate 10 that constitutes the advancement device 3. It is a part that can be freely engaged. The spring fixing portion 7 is a portion for fixing one end of the spring 11 constituting a part of the advancement instrument 3.

  As shown in FIGS. 1 and 2, the advancement tool 3 includes a push plate 10 and a spring 11. The push plate 10 is in contact with the product 4 located at the rearmost portion, and presses the entire product 4 forward by the force of the spring 11. The spring 11 is a spiral leaf spring to which winding is attached. As shown in FIG. 2, the winding portion 11 a is arranged on the back side of the pressing plate 10, and one end 11 b of the case 2. The push plate 10 is pressed forward by being fixed to the spring fixing portion 7 (see FIG. 1).

  The push plate 10 according to this embodiment is a member made of a resin material as a whole. As shown in FIGS. 3 and 4, the front surface portion 20, the back surface portion 21, the rail sliding portion 23, the reinforcing portion 24, the lower portion It has a piece portion 26 and a spring guide portion 27. The front surface portion 20 has a predetermined vertically long shape that comes into contact with the product 4, and holes 22 that penetrate from the front surface portion 20 to the back surface portion 21 are divided into left and right, and a total of six holes are formed.

  The rail sliding portion 23 is a concave portion that engages with the rail portion 5 formed in the case 2, and is formed in a direction perpendicular to the push plate 10 when viewed from the side (FIGS. 2 and 4b). And an upper surface sliding portion 30 that slides on the upper surface of the rail portion 5 and a lower surface sliding portion 31 that slides on the lower surface of the rail portion 5.

  The reinforcing portion 24 is two substantially fan-shaped members erected on the back surface portion 21, and the winding portion 11 a of the spring 11 described above is formed in a space 32 defined between the two reinforcing portions 24. Is arranged. The lower piece portion 26 is a portion erected in a direction perpendicular to the back surface portion 21 in the vicinity of the lower end of the space 32 defined between the two reinforcing portions 24, and the rail described above is formed by the lower piece portion 26. A sliding portion 23 is configured.

  Explaining the configuration according to the present invention, a pair of wheels 32 and 32 are provided at the lower ends of the reinforcing portions 24 and 24 formed on the back surface portion 21 of the push plate 10. In this embodiment, the wheels 32 and 32 are connected by an axle 33. The reinforcing portions 24, 24 have wheel mounting portions 35, and the axles 33 of the wheels 32, 32 are inserted and fixed in the fitting grooves 36 of the mounting portions 35. The axle 33 has play in the fitting groove 36, particularly in the vertical direction.

As shown in FIG. 5, the lower end side of the outer periphery of the wheels 32, 32 is above the upper surface of the rail portion 5 arranged in the rail sliding portion 23, and there is no load on the push plate 10. In this case, as shown in FIG. 5, the gap A is erected in a state perpendicular to the rail portion 5 , and a gap A of less than several mm is provided between the upper surface of the rail portion 5 and the outer periphery of the wheels 32, 32. Is held. A gap B that is less than several mm is also provided between the lower surface of the rail portion 5 and the lower surface sliding portion 31.

  As described above, the reason why the lower end side of the wheels 32 and 32 is arranged slightly above the upper surface of the rail portion 5 with a gap A as described above is that the wheels 32 and 32 are only moved back when the push plate 10 is pushed back. It is because it aims to utilize. As described above, the relationship between the wheels 32 and 32 and the fitting groove 36 is such that the push plate 10 is moved rearward when the push plate 10 is pushed back in combination with the vertical play. Inclination, a sufficient load is applied to the wheels 32 and 32 to obtain a contact pressure, and the wheels 32 and 32 can be reliably rotated. Further, the gap is effective in causing the wheels 32 and 32 to follow a change in the situation such as a case-side rail portion or unexpected dirt adhesion.

  In addition, although it has been described above that it is best that the lower end side of the wheels 32 and 32 has a gap A from the upper surface of the rail portion 5 in the outer periphery thereof, in carrying out the present invention, so as not to have the gap A, Even if the wheels 32, 32 that are in contact with the lower end side of the wheels 32, 32 and the upper surface of the rail portion 5 are provided at the lower end on the back side of the push plate 10, it is clear that the operational effects of the present invention can be obtained. It is. In that case, the fitting groove 36 and the axle 33 are preferably provided with play. It is also possible to adopt a single wheel that is long in the axial direction.

  By providing the wheel 32 on the push plate 10, it becomes rolling frictional resistance. In general, the rolling friction coefficient is affected by various factors such as the mating material and surface condition, but it is said that the sliding friction coefficient is 1/20 to 1/100 or less. Accordingly, the friction cone derived from the friction coefficient becomes extremely sharper than that during sliding friction. That is, as shown in FIG. 5, it is only directly above the part in contact. Therefore, the range that can be worn with the power point to move is dramatically expanded. Therefore, it can be understood that the present invention is very effective for the commodity advance display device 1.

  6a and 6b, another example of mounting of the wheels 32 and 32 is shown. The wheels 32 and 32 are independent of each other, have a U-shaped attachment portion 35a when viewed from above, and are fitted by inserting the axles 33 and 33 into the fitting grooves 36 and 36 of the attachment portion 35a. The axles 33, 33 and the fitting groove 36 are preferably provided with play. The other parts are the same as those in the first embodiment, and thus the same numbers are given and the description is omitted.

  FIG. 7 shows an example in which the pressing plate 10 has an inclined portion 39 whose upper portion is inclined rearward in the middle in the vertical direction. In this example, the wheels 32 and 32 having the same conditions as those of the first embodiment described above are provided, and the wheels 32 and 32 come into contact with the rail portion 5 when pushed backward, and the smooth backward movement is performed. Naturally, it is the same as in the first embodiment, and the same parts are denoted by the same reference numerals and description thereof is omitted.

  In the third embodiment, since the upper part of the push plate 10 has the inclined portion 39 that is inclined backward, as shown in FIG. 7, the product 4 is brought into contact with the inclined portion 39 when the product is replenished. When pressed downward, the component force generates a backward pressing force, and while the push plate 10 is tilted backward, the wheel 32 comes into contact with the rail portion 5 and the push plate 10 is smoothly moved backward. For this reason, the product to be replenished can be smoothly inserted between the rearmost mounted product. As a result, “first-in first-out operation” of the product can be executed. The angle θ of the inclined portion 39 is suitably in the range of 30 degrees to 45 degrees.

In FIG. 8, similar to the above-described example, the basic shape of the push plate 10 in which the hole 22 shown in the first embodiment is formed is prepared in the example in which the push plate 10 has the inclined surface 39. This is an example in which another component 40 is attached to this so as to have the effect of the inclined surface 39.
The separate part 40 is bent and has an inclined surface 39 on one side and a fixing surface 41 on the other side. The fixing surface 41 has a protrusion 42, and the protrusion 42 is inserted into the hole 22 formed in the push plate 10 and coupled. Thus, the inclined surface 39 is obtained on the push plate 10. The effect of the inclined surface 39 is obtained in the same manner as in the third embodiment. Although not shown, it is possible to bond the separate component 40 using a double-sided tape.
