Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display rack, and more particularly to a display rack having a structure for reducing swing.

[0002]

2. Description of the Related Art Conventionally, display shelves include showcases for the purpose of selling products and showcases for the purpose of exhibit only, as in museums. However, any display shelves encounter an earthquake. If you do, the display shelves will rock,
There was an inconvenience such as damage to the product or other exhibits. Therefore, it is desired that the display shelf is devised so that the vibration during the earthquake is not input and the structure is reduced.

[0003]

However, at the present time, there is no display shelf having a structure for reducing the swing, and therefore, there is a risk of damaging valuable commodities or articles.

Therefore, an object of the present invention is to solve the above problems and provide a display shelf having a structure for reducing the swing.

[0005]

In order to achieve the above object, the display shelf according to the invention of claim 1 is a box-shaped base, and a box-shaped base whose upper surface is covered with the lower surface is opened. An outer frame, a hanging member connecting these between the outwardly extending portions provided on both upper sides of the base and the inwardly extending portions provided on both lower ends of the outer frame, and the base side. And a showcase main body placed on the upper surface of the outer frame.

The outer frame is swingably suspended from the base via a suspending member. Therefore, even if the base sways due to an earthquake, the sway is absorbed by the suspension member, so the sway of the outer frame and the showcase body placed on this is smaller than the sway of the base. Therefore, the swing of the showcase body during an earthquake is significantly reduced.

Further, the relative vibration between the base and the outer frame is damped by a damper provided between the base and the outer frame. In addition, this damper exerts a seismic control function to prevent the outer frame and the showcase body side from shaking even when light weight is applied to the outer frame or the showcase body side during normal times other than earthquakes, Preventing normal exhibitions from being disturbed.

In order to further reduce the shake of the showcase body during an earthquake, it is preferable to further provide laminated rubber between the outer frame and the showcase body to suppress the shake of the outer frame.

In the display shelf according to the invention of claim 2, a box-shaped base having an open upper surface, a box-shaped outer frame having an open lower surface covering the base from above, and an upper portion of the base. Mounted on the upper surface of the outer frame, and a damper that also functions as a suspension member that connects and arranges the outwardly extending portions provided on both sides and the inwardly extending portions provided at both lower ends of the outer frame. The structure has a showcase body.

In this structure, since the damper also functions as a suspending member for suspending the outer frame on the base in a swingable manner, it not only exerts the effect of suppressing the rolling of the showcase body due to the horizontal force of an earthquake, but also at the same time. It also exerts the effect of absorbing and buffering vertical vibration. Further, since the single damper has both the function as the hanging member and the function as the damper, it is possible to obtain a display shelf having a simple and economical structure. A damper with a return spring can be used as this damper.

According to a third aspect of the present invention, in the display shelf according to the first or second aspect, a weight is hung on the outer frame by a supporting member so that the outer frame can swing less.

By providing such a weight, it is possible to create a state in which the weight is largely moved and the swing of the outer frame is suppressed by its reaction, so that the swing of the outer frame can be further reduced.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to illustrated embodiments.

The display shelf shown in FIGS. 1 and 2 has a rectangular box-shaped base 1 having an open upper surface and a rectangular box-shaped outer frame having an open lower surface which covers the base 1 from above. 2 and four outwardly projecting portions 3 provided on both sides in one direction of the upper part of the base 1 and four inwardly projecting portions 4 provided on both sides in one direction of the lower end of the outer frame 2 are connected. The hanging member 5 is provided, and the showcase main body 7 is placed on the upper surface of the outer frame 2 via the laminated rubber 6.

The base 1 is constructed as a trolley in which four wheels (casters with stoppers) 10 are arranged on a bottom plate 11, and a rectangular hollow frame 12 is fixed on the bottom plate 11 to form a box. The outwardly projecting portion 3 is formed on the side surfaces of the hollow frame 12 which are formed in a shape of a circle and are opposed to each other in one direction.
Are formed one by one. The outward projecting portion 3 is composed of an outward projecting portion 13 formed on the upper part of the hollow frame 12 and a triangular plate attached directly below the projecting portion 13 with a screw 14 as shown in FIG. It is composed of a support fitting 15.

Similarly, the outer frame 2 includes a top plate 21, a hollow frame 22 hung from the peripheral edge thereof, and side faces of the lower end of the hollow frame 22 which face each other in one direction, to be precise, the base 1. A pair of inward projecting portions 23 are provided on opposite side surfaces of the projecting portion 3 facing outward, and a support metal fitting 25 made of a triangular plate is attached to the support metal fitting 25 with a screw 24 directly above the projection metal 23. The projecting portion 23 and the projecting portion 23 form the inward projecting portion 4.

In short, the outwardly projecting portion 3 of the base 1 and the inwardly projecting portion 4 of the outer frame 2 project in directions intersecting with each other in one direction in the horizontal plane, and when viewed from above, As shown in FIG. 2, some of them overlap each other.

The hanging member 5 which connects the outwardly extending portion 3 and the inwardly extending portion 4 in a swingable manner in the up-down direction is made of a metal rod, and is well shown in FIGS. 3 and 4. As can be seen, the upper end is formed as a ring portion 51 which is passed through the small hole 16 provided in the support fitting 15 and is joined at the welded portion 52 in a closed loop shape, and the lower end is passed through the small hole 25 provided in the support fitting 25. It is formed as a hanging hook portion 53.

With respect to the base 1, the suspension member 5 is suspended by the upper ring portion 51 of the suspension member 5 being passed through the small hole 16 of the support fitting 15, and the lower end hook portion 53 of the suspension member 5.
The outer frame 2 is hung by passing the small hole 26 through. That is, the base 1 and the outer frame 2 are connected to each other through the hanging member 5 in a parallelogrammatic link configuration. Therefore, if the base 1 sways due to the horizontal force of the earthquake, the small holes 16,
The suspension member 5 pivotally displaces and swings around two points of 26, and the lateral vibration of the base 1 is absorbed by the suspension member 5 and transmitted to the outer frame 2, that is, the outer frame 2 side, that is, the showcase. Body 7
The side is held horizontally and swings relative to the base 1. Therefore, the swing of the showcase body 7 at the time of an earthquake is considerably reduced.

However, with only the above-mentioned hanging structure, the outer frame 2 will shake even if a load is applied by touching the showcase body 7 side with a hand during normal display.

Therefore, as shown in FIGS. 2 and 3, a damper 8 is provided between the hollow frame 12 of the base 1 and the hollow frame 22 of the outer frame 2 both in the horizontal plane and in the vertical plane. It is arranged so as to be inclined, and its both ends are swingably attached to the hollow frames 12 and 22 by pivots 8a and 8b. Here, the inclination angle in the horizontal plane is indicated by θ, and the inclination angle in the vertical plane is indicated by α.

By providing the damper 8 in this manner, the movement of the outer frame 2 with respect to the base 1 is buffered, damped, and becomes slow, and it is possible to prevent inconvenience in the handling operation even during normal display. In addition, here, the hollow frame 12 of the base 1 on which the hanging member 5 exists and the hollow frame 2 of the outer frame 2
Although only one damper 8 is provided between each of them, the damper 8 is arranged so as to incline both in the horizontal plane and in the vertical plane as described above. It exhibits an effective damper function regardless of displacement in any of the front, rear, left and right directions and in the vertical direction in the vertical plane.

On the other hand, even if such a damper 8 is provided, the outer frame 2 cannot be shaken at all, but a laminated rubber 6 is further provided between the outer frame 2 and the showcase body 7. Since it is interposed, the laminated rubber 6 further suppresses the swing of the outer frame 2. The showcase body 7 slides on the side surface of the showcase body 7 so that the outer frame 2
In order to prevent the situation from deviating from the above, a stopper 27 as a side plate is attached to the side surface of the showcase body 7.

FIGS. 5 and 6 show another embodiment. In the example of FIGS. 1 and 2, a weight 9 having a predetermined mass is suspended from the outer frame 2 by a supporting member 28 such as spring steel. The difference is that a so-called dynamic damper is formed to absorb the swing of the outer frame 2 so that it can be made smaller.

In this example, one end of the support member 28 is fixed to the lower surface of the top plate 21 of the outer frame 2 and a weight 9 is provided at the other end to freely position the hollow member 12 in the hollow frame 12. A weight 9 is provided. By providing the weight 9 which can freely swing in this manner on the outer frame 2, it is possible to create a state in which the weight 9 largely moves but the swing of the outer frame 2 is suppressed, and thus the outer frame 2 is prevented from swinging. The swing can be further reduced.

FIG. 7 and FIG. 8 show still another embodiment. This uses a damper 54 having a built-in return spring as the suspension member 5 and omits the damper 8 in FIGS. 5 and 6.

The damper 54 as the suspension member 5 is
The upper end on the cylinder side is the small hole 1 provided in the support fitting 15.
The hook portion 53 is formed as a ring portion 51 that is connected to the welded portion 52 in a closed loop shape through 6 and the lower end on the piston side is hung through a small hole 25 provided in the support fitting 25.
It is formed as. Further, unlike a normal damper, a return spring (not shown) that connects the cylinder side and the piston side is provided between the cylinder side and the piston side.

Therefore, the damper 54 also functions as a suspending member 5 for suspending the outer frame 2 on the base 1 so as to swing, and against the horizontal force transmitted from the base 1 side when an earthquake occurs. Not only does it have an effect of buffering and suppressing the swing of the outer frame 2, that is, the showcase main body 7, but also functions to buffer the vertical vibration even when the base 1 vertically shakes in the vertical direction due to an earthquake. Eggplant Therefore, one damper 5
In 4, the display shelf having a simple and economical structure can be obtained by combining the function as the hanging member 5 and the function as the damper 8.

In the above-described embodiment, the outwardly projecting portion 3 is provided.
Although the inwardly extending portion 4 and the inwardly extending portion 4 are partially provided around the base 1 and the outer frame 2, the outwardly extending portion 3 is provided as an outward flange around the entire periphery of the base 1, and also inwardly extending. The overhanging part 4 of the outer frame 2
It can also be provided as an inward flange on the lower end of the entire circumference.

[0030]

As described above, according to the first aspect of the invention, the outer frame is suspended from the base by the suspending member, so that the base can roll sideways due to an earthquake. Since the shaking is absorbed by the hanging member, the shaking of the outer frame and the showcase body placed on it is smaller than the shaking of the base, which is equivalent to the shaking of the showcase body during an earthquake. It can be reduced.

The relative vibration between the base and the outer frame can be damped by a damper provided between the base and the outer frame. Even if a light weight is applied to the frame or the showcase body side, it exerts a damping function that buffers and regulates so that the outer frame and the showcase body side do not shake relative to the base, and during normal exhibition Prevent inconvenience.

According to the second aspect of the invention, since the damper is also used as a suspension member for suspending the outer frame on the base in a swingable manner, the damper also swings the showcase body against the horizontal force of the earthquake. Not only can the movement be absorbed and suppressed, but also when the base is vertically pitched by an earthquake, the vertical vibration can be absorbed and buffered. Further, since one damper has both a function as a suspension member and a function as a damper, it is possible to obtain a display shelf having a simple and economical structure.

According to the third aspect of the present invention, by suspending the weight on the outer frame by the support member, it is possible to create a state in which the swing of the outer frame is suppressed by the reaction of the weight while the weight can be largely moved. The swing of the frame can be further reduced.
