Description

  The present invention relates to a display shelf adjuster unit that is attached to adjust the level of a display shelf body that displays a display object, and a display shelf with a seismic isolation function provided with the adjuster unit.

  For example, storage furniture for general households is taller and larger in size to ensure storage capacity. In this case, the weight increases, and in particular, when it is installed on a soft floor such as a tatami mat, it may be difficult to ensure stability because it partially sinks due to its own weight. For this reason, there is already known an adjuster attached to the lowermost surface of the storage furniture so as to maintain the stability by adjusting the level (see, for example, Patent Document 1).

Japanese Utility Model Publication No. 58-29970

  By the way, in general, display shelves such as supermarkets and convenience stores often have a tall configuration in order to accommodate a large amount of displayed products and make them easy to see from the customer side. For this reason, the leveler is usually adjusted by providing an adjuster as in the above-described prior art also in a display shelf in a store.

  In recent years, stores, in particular, grocery stores and convenience stores have attracted attention as a function as a lifeline in the event of a disaster. Therefore, some seismic isolation measures are urgently desired so that the displayed items do not fall as much as possible even when an earthquake or the like is encountered. Although the above-mentioned conventional adjusters have a leveling adjustment function, they do not have such a seismic isolation function, and are insufficient to meet the recent demands as described above. In particular, convenience stores often operate 24 hours a day, and in that case, there are no non-business hours. Therefore, it is preferable that seismic isolation measures can be easily and quickly performed with minimum effort during business hours.

  In view of the above, there has been a demand for an adjuster having a seismic isolation function that can be easily and quickly installed with minimum effort by incorporating it later into an existing display shelf.

  An object of the present invention is to provide an adjuster unit for a display shelf that can perform both horizontal adjustment and seismic isolation function easily and quickly with a minimum of effort by being retrofitted to an existing display shelf, and a seismic isolation device having the same The purpose is to provide a functional display shelf.

  In order to achieve the above object, the first invention is a display shelf adjuster unit which is attached to adjust the level of the display shelf main body for displaying the display object, and is provided at the bottom; provided at the top; An adjuster body comprising: a connecting member that connects the bottom part and the head part so as to be swingable; and a screwing member that is screwed into the head part in a variable axial direction. And an attachment member for attaching to the lower part of the display shelf body.

  In the first invention, the bottom portion and the head portion of the adjuster body are connected to each other by the connecting member so as to be swingable. Therefore, the vibration can be absorbed by relative swinging between the head side and the bottom side. At this time, the screwing member is screwed into the head portion on one side that relatively swings, and thereby the axial position of the screwing member is configured to be variable.

  Such an adjuster main body is attached to the lower part of the display shelf main body via an attachment member. As a result, the adjuster main body is attached to the display shelf main body at a plurality of positions, and the axial position of the screwing member is adjusted by each adjuster main body (= expands and shrinks in the axial direction as a whole). Can be adjusted. At this time, since the vibration can be absorbed by the relative swinging of the head and the bottom as described above, even if the display shelf is shaken with respect to the ground due to an earthquake or the like, the vibration is absorbed and immunized. Can perform seismic function.

  Further, when it is desired to install the adjuster body composed of the bottom part, the connecting member, the head, and the screw member as described above on the display shelf, each adjuster body is attached to the attachment member in advance, and this attachment member is directly attached to the display shelf body. It is sufficient to install it at the bottom. In other words, the adjuster body can be attached to the lower portion of the display shelf body later without moving the display shelf body. As a result, the seismic isolation measures can be easily and quickly executed with a minimum of effort even during, for example, the business hours of the store.

  According to a second invention, in the first invention, the attachment member is attached to the lower part of the display shelf main body on the end side, and attached to the display shelf main body on the end side on the side opposite to the end part. The upper portion of the screwing member of the adjuster main body is connected to the lower portion of the adjuster body.

  In 2nd invention, in the state which attached the edge part of the attachment member to the lower part of the display shelf main body, the opposite side to an edge part is located above an edge part. Thereby, since the upper part of the screwing member of the adjuster body is connected, the swing center of the adjuster body that vibrates horizontally is located above the end of the attachment member. As a result, the adjuster body is stably supported.

  According to a third invention, in the second invention, the adjuster main body is provided with two left and right corresponding to the left and right direction of the display shelf main body, and the mounting member has both left and right end portions thereof, The left and right side wall lower portions of the display shelf main body are respectively attached, and the center portion in the left-right direction is located above the both end portions in the attached state of the both end portions to the display shelf main body. The upper parts of the screwing members of the adjuster body are connected to each other.

  In the third invention, two adjuster bodies are provided on the left and right sides corresponding to the left-right direction of the display shelf body. As a result, the adjustment of the level is effective, the support is stabilized, and the left and right central portions are located above the both ends in the state where both ends are attached to the display shelf body, and the two adjusters are disposed below the two adjusters. Since the upper part of the screwing member of the main body is connected to each other, the display shelf main body can be supported in a stable state.

  In a fourth aspect based on the third aspect, the attachment member is attached so that both left and right end portions of the attachment member sink into the lower part of the horizontal portion of the left and right side walls each having a substantially L shape. It is characterized by being able to.

  In 4th invention, the substantially L shape is provided in each of the both ends of the left-right direction of an attachment member. Thereby, an attachment member can be attached so that it may sink into the space formed in the horizontal part lower part of a display shelf main body lower part.

  5th invention is equipped with the built-in adjuster for adjusting levelness, and is attached separately from the said built-in adjuster in order to adjust the level of the display shelf main body which displays a display thing, and the said display shelf main body, and is attached. In some cases, it has a display shelf adjuster unit that performs the seismic isolation function while invalidating the leveling adjustment function of the built-in adjuster.

  In the fifth aspect of the invention, a display shelf adjuster unit is newly attached to the display shelf main body in which the built-in adjuster is already installed, separately from the built-in adjuster. This adjuster unit disables the leveling adjustment function of the existing built-in adjuster and instead adjusts the leveling itself, and absorbs the shaking even when the display shelf is shaken with respect to the ground. The seismic isolation function can be fulfilled.

  At this time, the adjuster is made into a unit having a configuration different from that of the display shelf main body, and by attaching the adjuster, the leveling adjustment function of the existing built-in adjuster is invalidated, so that it is not necessary to remove the built-in adjuster. As a result, seismic isolation measures can be implemented easily and quickly with minimal effort.

  In a sixth aspect based on the fifth aspect, the display shelf adjuster unit includes: a bottom portion provided at a lower portion; a head portion provided at an upper portion; a connection that connects the bottom portion and the head portion so as to be swingable with respect to each other. An adjuster main body comprising: a member; a screwing member that variably engages with the head in an axial direction; and an attachment member that attaches the adjuster main body to a lower portion of the display shelf main body.

  In the sixth invention, the bottom portion and the head portion of the adjuster body of the adjuster unit are connected to each other by the connecting member so as to be swingable. Therefore, the vibration can be absorbed by relative swinging between the head side and the bottom side. At this time, the screwing member is screwed into the head portion on one side that relatively swings, and thereby the axial position of the screwing member is configured to be variable.

  Such an adjuster main body is attached to the lower part of the display shelf main body via an attachment member. As a result, the adjuster main body is attached to the display shelf main body at a plurality of positions, and the axial position of the screwing member is adjusted by each adjuster main body (= expands and shrinks in the axial direction as a whole). Can be adjusted. At this time, since the vibration can be absorbed by the relative swinging of the head and the bottom as described above, even if the display shelf is shaken with respect to the ground due to an earthquake or the like, the vibration is absorbed and immunized. Can perform seismic function.

  Further, when it is desired to install the adjuster body composed of the bottom part, the connecting member, the head, and the screw member as described above on the display shelf, each adjuster body is attached to the attachment member in advance, and this attachment member is directly attached to the display shelf body. It is sufficient to install it at the bottom. In other words, the adjuster body can be attached to the lower portion of the display shelf body later without moving the display shelf body. As a result, the seismic isolation measures can be easily and quickly executed with a minimum of effort even during, for example, the business hours of the store.

  According to the present invention, by retrofitting an existing display shelf, both leveling adjustment and seismic isolation measures can be executed easily and quickly with minimal effort.

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

It is fixed and covered. As a result, a predetermined storage space surrounded by the cover plates 15 and 16 is formed on the lower surface of the shelf board 11. In this storage space, four display shelf adjuster bodies H are arranged in the vicinity of the lower four corners of each shelf board 11, and the display shelf 1 body is supported by a total of 16 display shelf adjuster bodies H. Has been.

  Next, the display shelf adjuster unit T according to the present invention will be described with reference to FIGS. FIG. 4 is a cross-sectional view of the adjuster body T provided at the lower portion of the display shelf body 1, and corresponds to an enlarged view of the IV portion in FIG. FIG. 5 is a detailed cross-sectional view of the adjuster body T, and corresponds to an enlarged view of a portion V in FIG. FIG. 6 is a top view taken along arrow A in FIG.

  4 to 6, the display shelf adjuster unit T of the present embodiment includes a bottom housing 22 provided at a lower portion, a head housing 24 provided at an upper portion, and the bottom housing 22 and the bottom housing 22. An adjuster body H including a rod 23 serving as a connecting member that is swingably connected, and a case body 25 that is a bottomed cylindrical screw member that is screwed into the head housing 24 in a variable axial direction. And a bridge 28 as an attachment member for attaching the adjuster main body H to the lower portion of the display shelf main body 1.

  The head housing 24 has a flange 24a as a screwing member formed on an upper surface thereof, and a male screw G screwed to a female screw E screwed to the inner wall of the case body 25 is screwed on the outer periphery thereof. The head housing 24 is rotated in a predetermined direction by screwing the male screw G of the flange 24a of the head housing 24 into the inner wall of the case body 25, so that the head housing 24 is rotated in the predetermined direction. It is adapted to be screwed in (see FIG. 5).

  At this time, the case body 25 has a circular operation shaft 25a protruding from the upper surface. The operation shaft 25a has an operation hexagon hole 35 (see FIG. 6) formed on the upper end surface thereof, and is configured to be inserted and protruded from the upper surface of the bridge 28 as an attachment member. Then, the operation shaft 25a is inserted through an attachment hole (not shown) of the bridge 28, and the stop ring 26 is elastically attached to the annular groove of the operation shaft 25a protruding from the upper surface thereof, whereby the case body 25 is attached to the bridge 28. Is supported.

  The bridge 28 is formed of, for example, a steel plate having a U-shaped cross section (see FIG. 6), and attachment portions 29 that are bent in an L shape are provided at both ends thereof (FIGS. 5 and 6). reference). The bridge 28 is spanned so as to be parallel to the lower surface of the lowermost shelf 11 of the display shelf main body 1, and the horizontal covering plates 16, 16 provided on the left and right of the lower portion of the display shelf main body 1, Both the attachment portions 29, 29 are attached (see FIGS. 1 and 5). As described above, the bridge 28 is provided in a space formed on the lower surface of the lowermost shelf 11 at the lower part of the display shelf body 1 by providing the substantially L-shaped attachment portions 29 at both the left and right ends of the bridge 28. Can be attached to dive.

  The bottom housing 22 is formed with a flange 22a on the lower surface to be grounded and supported by the floor surface F.

  At both upper and lower ends of the rod 23, spherical concave portions 32 each having a substantially spherical concave shape are provided. Bearing heads 24 b and 22 b corresponding to the spherical recesses 32 are loaded in the head housing 24 and the bottom housing 22, respectively. The spherical heads 24 b and 22 b of the bearings of the head housing 24 and the bottom housing 22 are slidably inserted into the spherical recesses 32 and 32, thereby constituting a universal joint. In this way, a plurality of adjuster bodies H to which the bottom housing 22 and the head housing 24 are swingably connected via a universal joint having a spherical recess 32 are attached to the bridge 28.

  Next, an example of a procedure for attaching the display shelf adjuster unit T to the display shelf body 1 will be described.

  First, a plurality of case bodies 25 are attached to the bridge 28, the head housings 24 are screwed into the case bodies 25, and the flanges 24a of the head housing 24 are brought into contact with the bottom surfaces of the case bodies 25. It is set as the state which entered.

  On the other hand, the spherical head 22b of the bottom housing 22 is inserted into the spherical recess 32 at the lower end of the rod 23 in advance, so that the bottom housing 22 and the rod 23 are integrated. Then, the upper end of the compression spring S is brought into contact with the lower surface of the flange 24a of the head housing 24 accommodated in the case body 25, and the above-mentioned (( The rod 23 (integrated with the bottom housing 22) is inserted, and the spherical head 24b of the head housing 24 is inserted into the spherical recess 32 at the upper end. As a result, the flange 22a of the bottom housing 22 is pressed and urged downward by the urging force of the compression spring S, and the plurality of adjuster bodies H are attached to the lower surface of the bridge 28 while being pressed and urged. By repeating this operation, a total of four adjuster bodies H (see FIG. 3) can be attached to each bridge 28 in correspondence with the left and right directions of the display shelf body 1.

  Then, by removing the lowermost shelf 11 from the cover plates 15 and 16 of the display shelf body 1 as described above, the bridge 28 to which the adjuster body H is attached can be inserted into the storage space from above. By attaching the lower ends of the L-shaped attachment portions 29 at both ends of the inserted bridge 28 to the horizontal covering plate 16 with two attachment screws B, one display shelf adjuster unit T is completed. In this example, four display shelf adjuster units T are provided in the left-right direction of one display shelf body 1 (see FIGS. 3 and 4).

  In the state immediately after the installation of the display shelf adjuster unit T as described above, the display shelf body 1 is horizontally supported on the floor surface F by the plurality of built-in adjusters R (the bottom of the adjuster unit T). The lower surface of the housing 22 is not grounded to the floor surface F). From this state, for example, a tool for turning a screw (hexagon wrench) is fitted into the hexagonal hole 35 in the operation hole on the upper end surface of the operation shaft 25 a protruding from the upper surface of the bridge 28, and the case body 25 is attached to the head housing 24. Rotate in a predetermined direction. As a result, the head housing 24 moves downward, and the bottom housing 22 is pushed downward, so that the adjuster body H extends downward (the axial dimension increases). Accordingly, the bottom surface of the bottom housing 22 of the adjuster unit T is grounded to the floor surface F, and when further extended, the display shelf main body 1 moves upward, and the built-in adjuster R rises to the floor surface F. A gap D is formed. As a result, the leveling adjustment function of the existing built-in adjuster R is invalidated, and the display shelf body 1 is horizontally supported by the individual display shelf adjuster units T.

  As described above, the adjuster unit main body H can be attached to the lower portion of the existing display shelf main body 1 by retrofitting, and the installation work of the adjuster main body can be simplified.

  According to the present embodiment configured as described above, a display shelf adjuster unit T is newly attached to the display shelf main body 1 in which the built-in adjuster R is already installed, separately from the built-in adjuster R. This adjuster unit T disables the leveling adjustment function of the existing built-in adjuster R and adjusts the leveling by itself, and even when the display shelf body 1 is shaken with respect to the ground. It absorbs this shaking and performs a seismic isolation function.

  That is, in the adjuster unit T, the bottom housing 22 and the head housing 24 of the adjuster body H are connected to each other by the rod 23 so as to be swingable. Therefore, the vibration can be absorbed by the relative swinging of the head housing 24 side and the bottom housing 22 side. At this time, the case body 25 is screwed into the head housing 24 which is one side which relatively swings, and thereby the axial position of the case body 25 is configured to be variable. Such an adjuster body H is attached to the lower part of the display shelf body 1 via the bridge 28. Then, as described above, by adjusting the axial position of the case body 25 of each adjuster body H attached to the display shelf body 1 at a plurality of locations (= extending and contracting in the axial direction as the entire adjuster body H), The level of the display shelf body 1 can be adjusted. At this time, since the vibration can be absorbed by the relative swing between the head housing 24 and the bottom housing 22 as described above, even when the display shelf body 1 is shaken with respect to the ground due to an earthquake or the like, The seismic isolation function can be achieved by absorbing this shaking.

  When it is desired to install each adjuster main body H on the display shelf main body 1, as described above, each adjuster main body H is previously attached to the bridge 28 to form an adjuster unit T, and the bridge 28 is used as it is. It is sufficient to attach to the lower part of 1. That is, the adjuster unit T can be attached to the lower portion of the display shelf body 1 later without moving the display shelf body 1 almost. Furthermore, since the adjuster unit T is attached to invalidate the function of adjusting the level of the existing built-in adjuster R, there is no need to remove the built-in adjuster R. As a result, the seismic isolation measures can be easily and quickly executed with a minimum of effort even during, for example, business hours of a store.

  In the present embodiment, in particular, when the bridge 28 is attached to the lower part of the display shelf body 1, the bridge 28 is located on the opposite side (that is, the center side) to the lower end of the attachment portion 29 at both ends of the bridge 28. An attachment surface for attaching the case body 25 is located above the lower end of the attachment portion 29. Thus, the ball head 24b in the head housing 24, which is the center of swinging of the adjuster main body H that horizontally oscillates, is located above the mounting positions at both ends of the bridge 28, so that the adjuster main body H is stable. Supported. Further, two adjuster bodies H are provided on the left and right sides corresponding to the left and right directions of the display shelf body 1. Thereby, the adjustment of the levelness is effective and the support is stabilized.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
