Description

  The present invention relates to a structure that effectively protects an edge of a top plate from an impact.

  Conventionally, an attachment structure that can effectively protect the end surface of the top plate by attaching one or more edge members to the end surface of the top plate has been proposed (see, for example, Patent Document 1).

  For example, the above-mentioned Patent Document 1 realizes a so-called ship bottom shape in which the top plate can be seen thinly by attaching an elastically deformable edge member to the lower end of the end face so as to face the inclined direction. . With such a ship bottom shape, the elastic deformation of the edge member not only absorbs the impact in the direction from the side to the lower side with respect to the edge of the top plate, but also the outer surface faces the tilt direction, It has a structure that can effectively escape in the other direction.

On the other hand, the edge portion having such a ship bottom shape can also be configured by injecting urethane into the lower end portion of the end surface of the top plate, for example.
JP-A-2005-253618

  However, with the structure as described above, the edge member and the injected urethane can surely absorb the impact from the outside, but the elastic repulsion force is not only on the outside of the top board but also on the top board itself. It will work.

  In that case, the top plate is greatly moved by the elastic repulsion force. As a result, what is arranged on the top plate is moved greatly, and in some cases, it will fall down.

  On the other hand, if the top plate can move, the top plate may move due to the impact, and it may collide with other furniture such as the elbow of a chair from the actual office situation. Can happen.

  This invention pays attention to such a malfunction, and provides the structure which can absorb the impact with respect to the edge part of a top plate effectively.

  In order to achieve such an object, the present invention takes the following measures. That is, the shock absorbing structure for the top plate edge according to the present invention forms an outer shape of an edge member that fits into the edge mounting portion formed at the lower end of the end surface of the edge of the top plate and can be elastically deformed. An edge forming surface that can continue in an obliquely downward direction to the upper end portion and the lower end portion, a continuous end that contacts the upper end portion and the lower end portion of the edge attachment portion on the edge formation surface, the edge attachment portion, and the edge member And at least a buffer space formed between the two.

  Here, in this specification, “upper” and “lower” do not depend on the direction in which the top plate itself faces, and are described as the vertical direction in a state where the top surface of the top plate is horizontal.

  If this is the case, the edge forming surface constituting the so-called ship bottom shape not only has the effect of releasing the impact unique to the ship bottom shape, but the buffer space is appropriately deformed by receiving the impact, so the edge member It is possible to effectively relieve the impact transmitted directly to the end face of the top plate. By doing so, it is possible to effectively avoid problems such as giving a large impact to the top plate or moving the top plate unexpectedly, and overturning the one placed on the top plate, It is possible to effectively eliminate the problem of further colliding with other furniture such as the elbow of the chair.

  And the edge part of a top plate is not restricted to what is always making linear form, For example, curved shape, ie, a round may be formed with the planar view shape of a top plate. Further, in such a case, the edge member is bent at the location where the radius is formed, and is pulled to the outer circumference of the radius, and a compression force is generated on the inner circumference side, thereby changing the cross-sectional shape of the edge member. That is, there may be a case where the continuous end cannot contact the upper end portion and the lower end portion of the edge mounting portion accurately and continuously due to a change in the sectional view shape of the edge member. In addition, the tendency increases as the size of the edge member with respect to the edge of the top plate increases. Therefore, in the present invention, such a continuous end is a pressing continuous end that is in contact with the upper end portion and the lower end portion of the edge mounting portion being elastically biased, so that the continuous pressing end is elastic even if the sectional view shape changes. Stable mounting because the repulsive force can maintain an accurate continuous state at the edge mounting part and the buffer space suitably allows changes in the cross-sectional view shape even when the edge member size is large. The state can be realized.

  In particular, in the present invention, if the buffer space includes an upper and lower buffer space that interposes the edge mounting portion and the edge member in the vertical direction and a horizontal buffer space that intervenes in the horizontal direction, The vertical buffer space effectively absorbs the impact that is the component of the direction, and the horizontal buffer space effectively absorbs the impact that is the component of the horizontal direction, thereby effectively absorbing the impact from all directions from the vertical direction to the horizontal direction. Can be obtained.

  In order to enable the edge member to be suitably positioned with the edge member mounted, the edge member is brought into contact with the edge mounting portion in a mounting state in which the upper end portion and the lower end portion of the edge mounting portion are connected to the continuous end. It is desirable to further have an abutting portion that comes into contact.

  As a configuration for suitably attaching the edge member, an attachment groove capable of attaching the edge member to the edge attaching portion and an insertion protrusion capable of being inserted into the attachment groove are provided in the edge member. be able to.

  In order to make the change in the shape of the edge member inconspicuous due to the change in the shape of the edge of the top plate in plan view, it is desirable that the edge forming surface be a bulged surface that is bulged in cross section. In particular, as a configuration for making the edge of the top plate suitable in appearance, it is preferable that the bulging surface is bulged into a partial circle.

And as a specific aspect of the edge mounting structure of such a top plate, an upper edge member capable of covering the side of the top plate from the upper end of the edge of the top plate to the upper end of the edge mounting portion is further provided. However, it is desirable that the lower end portion of the upper edge member is continuous with the continuous end. If it is such, the upper edge member and the edge member can effectively protect the end surface of the top plate. Further, by selecting a color scheme between the upper edge member and the edge member, it can be made suitable in appearance.
In the upper edge member, as a configuration that can effectively suppress deformation of the cross-sectional shape due to the plan view shape of the top plate, it is formed by hanging down in a straight line shape in cross-sectional view from the upper end of the edge of the top plate to the upper end of the edge mounting portion The upper edge member may be formed in a flat plate shape.

  In particular, in order to effectively protect the top surface of the top plate from an impact from the side to the top plate and maintain the appearance of the top plate suitably, it is desirable that the upper edge member is made of a hard material.

Here, the term “hard member” as used herein refers to a material whose cross-sectional shape is hardly deformed by an impact from the outside. Examples of such a hard member include ABS resin.
And if the shock absorbing structure for the top plate edge according to the present invention is applied to the top plate that can move relative to the base supporting the top plate, the top plate can be moved when the top plate is moved. Even when it collides with the furniture, the impact can be effectively absorbed.

  According to the present invention, the edge forming surface constituting the so-called ship bottom shape not only has the effect of releasing the impact unique to the ship bottom shape, but the shock absorbing space is appropriately deformed by receiving the impact, so that the edge member receives the impact. Direct transmission to the end surface of the top plate can be effectively mitigated. By doing so, it is possible to effectively avoid problems such as giving a large impact to the top plate or moving the top plate unexpectedly, and overturning the one placed on the top plate, It is possible to effectively eliminate the problem of further colliding with other furniture such as chair elbows.

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

More specifically, in the furniture A with a top plate, the top plate portion T supported by the base B via the bracket BR extends along the extending direction of the base body B1 supported by the base leg B2 in the base B. It is configured to be able to slide through the bracket BR. In addition, since the top plate T has a structure that can be easily turned by operating a lever (not shown) with respect to the bracket BR, the user can slide and turn the top plate T as appropriate, so that the top plate T can be suitably arranged at a desired position. And since the top-plate part T has the top-plate leg 4 which has a caster, it can change an arrangement | positioning easily, being supported with respect to the base B easily. In addition, in the same figure, although it is set as the structure which has arrange | positioned the other top plate TT supported so that it cannot move with respect to the base B to the other side via the base B from the top plate part T, the said furniture A with a top plate is shown.

  Here, the shock absorbing structure S according to this embodiment forms an outer shape of the edge member 2 that fits into the edge mounting portion 11 formed at the lower end of the end surface 10 of the edge portion 1e of the top plate 1 and can be elastically deformed. An edge forming surface 21 that can continue in an obliquely downward direction to the upper end portion 14 and the lower end portion 15 of the attachment portion 11, and a continuous end that contacts the upper end portion 14 and the lower end portion 15 of the edge attachment portion 11 on the edge formation surface 21. It includes at least an upper pressing end 24 and a lower pressing end 25, which will be described later, and an upper and lower buffering space s1 and a horizontal buffering space s2 constituting a buffering space formed between the edge mounting portion 11 and the edge member 2. It is characterized by.

  Hereinafter, the impact absorbing structure S will be described in detail by specifically describing each component of the top panel T.

  As shown in FIGS. 2, 3, and 4, the top plate 1 includes an upper surface 1 a coated with, for example, melamine resin, an upper surface 1 b covered with, for example, a backer material, and an upper edge at the edge of the top plate 1. It has the structure which has the end surface 10 containing the attaching part 12 and the edge attaching part 11. FIG. The upper edge mounting portion 12 is formed so as to vertically face a position continuous with the edge of the upper surface 1 a and a position continuous with the upper end portion 14 of the edge mounting portion 11, thereby forming a flat upper edge member. 3 is formed so that it can be suitably attached. Here, in the manufacturing process, the top plate 1 according to the present embodiment, in a state where the upper edge member 3 is attached to the upper edge attaching portion, partially extends laterally from the portion corresponding to the upper end portion 14. It is assumed that a method of forming the edge attaching portion 11 by simultaneously cutting a part and a part of the top plate 1 is adopted. By such a method, the upper edge member 3 and the upper end portion 14 of the edge attaching portion 11 have a shape that can be suitably continued. In addition, the edge part 1e of the top plate 1 in the same figure has shown the linear part 1s extended | stretched linearly.

  As shown in FIGS. 2, 3, and 4, the edge mounting portion 11 is formed by notching the lower end of the edge portion of the top plate 1 in a partial arc shape in a sectional view, and the edge member 2 is formed at the notched portion. It can be attached to embed. The upper end of the edge mounting portion 11 is preferably continuous with the lower end 34 of the upper edge member 3, and the lower end portion 15 is preferably continuous with the upper surface 1 b of the top plate 1. And the attachment groove | channel 13 which can attach the edge member 2 is formed by notching along the surface direction of the top plate 1 in the slightly upper position from the lower end part 15. As shown in FIG.

  As shown in FIGS. 2, 3, and 4, the upper edge member 3 is formed by a hard member into a band shape, in other words, a flat plate shape. Specifically, as shown in FIGS. 3 and 4, the upper edge member 3 is moved from the position corresponding to the upper edge mounting portion 12, that is, from the upper end 33 positioned at the upper end of the edge 1 e of the top plate 1 to the edge mounting portion 11. The attachment surface 32 is adhered to the end surface 10 over the upper end of the surface, and the side surface of the top plate 1 is covered to expose the surface 31. And the lower end 34 of this upper edge member 3 comprises the upper end part 14 of the edge attachment part 11 in this embodiment, and the surface 31 of the upper edge member 3 and the edge formation surface 21 of the edge member 2 continue suitably. It is supposed to be. And in the state which attached the upper edge member 3, as shown to the same figure, it has comprised in the state hung down linearly in the cross section view from the edge 1e upper end of the top plate 1 to the upper end of the edge attaching part 11. . In the present embodiment, the hard member needs to be able to bend according to the plan view shape of the top plate 1, but various materials can be adopted as long as it does not elastically deform in the cross-sectional view shape. It is.

  The edge member 2 is formed by integral molding using, for example, an elastically deformable synthetic resin. As shown in FIGS. 2, 3, and 4, the edge member 2 is formed on the edge mounting portion 11 formed on the end surface 10 of the top plate 1. It can be inserted and elastically deformed. Then, an edge forming surface 21 that can be continuous with the upper and lower ends of the edge mounting portion 11, and an upper portion that is a pressing continuous end that contacts the upper end portion 14 and the lower end portion 15 of the edge mounting portion 11 on the edge forming surface 21 in an elastically biased state. It has a pressing end 24 and a lower pressing end 25, an upper and lower concave portion 26 that can form the deformation allowable space according to the present invention together with the edge mounting portion 11, and a horizontal concave portion 27 that can also form a deformation allowable space. . In the figure, the edge member 2 is in a straight line state ST along the straight portion 1 s in the edge portion 1 e of the top plate 1.

  As shown in the figure, the edge forming surface 21 is set so as to face obliquely downward, and the edge 1e of the top plate 1 can form a so-called ship bottom-like cross section. The edge forming surface 21 is a bulged surface that is bulged in cross section. More specifically, it has a shape bulged into a partial circle.

  As shown in the figure, the upper pressing end 24 is a position located on the uppermost side of the edge member 2, and the upper end of the edge mounting portion 11 is shifted from the state shown in FIG. The upper edge member 3 constituting the portion 14 is pressed against the lower end 34 in a state where an elastic repulsion force is accumulated.

  As shown in the figure, the lower pressing end 25 is located on the lowermost side in the edge member 2 and is moved to the state shown in FIG. 3 from the state shown in FIG. 15 is pressed in a state where an elastic repulsion force is accumulated at the end of the lower surface 1b constituting the portion 15.

  The upper and lower recesses 26 are formed by recessing the upper part of the edge member 2. In the state shown in FIG. 4, the upper and lower buffer space s <b> 1 constituting the buffer space described in detail later can be formed together with the edge mounting portion 11.

  The horizontal recess 27 is formed by partially recessing the inner side of the edge member 2, specifically, the upper and lower sides of the insertion protrusion 22. And in the state shown in FIG. 4, the horizontal buffer space s2 which comprises the buffer space explained in full detail later with the edge attaching part 11 can be formed.

  In this embodiment, the insertion ridge 22 contacts the edge mounting portion 11 with the upper end portion 14 and the lower end portion 15 of the edge mounting portion 11 and the upper pressing end 24 and the lower pressing end 25 continuously connected. It functions as a contact part in the invention. In addition, the insertion protrusion 22 can be inserted into the mounting member 13 in the edge member 2. A wave-shaped retaining portion 23 is formed in a direction orthogonal to the rising direction of the insertion protrusion 22.

  Thus, the shock absorbing structure S according to the present embodiment includes an edge forming surface 21 that can form the edge 1e of the top plate 1 in a cross-sectional view bottom shape, and the upper end of the edge mounting portion 11 on the edge forming surface 21. And a continuous end in contact with the lower end portion, and an upper and lower buffer space s1 and a horizontal buffer space s2 which are buffer spaces formed between the edge mounting portion 11 and the edge member 2.

  Here, the behavior when the edge member 2 effectively absorbs the impact from the outside by the impact absorbing structure S according to the present embodiment will be described with reference to FIGS. 5 and 6.

  The figure shows the behavior of the edge member 2 when another furniture H such as an elbow of a chair collides from the side and from below. More specifically, as shown in FIG. 5, when the edge member 2 receives an impact from the side, the impact is absorbed by the elastic deformation of the edge member 2 itself and the horizontal buffer space s2 has a sectional view shape. Is changed, the impact transmitted to the end surface 10 of the top plate 1 is effectively mitigated. On the other hand, as shown in FIG. 6, when the edge member 2 receives an impact from below by another furniture H, for example, when the elbow of the chair is flipped up, the impact is absorbed by the elastic deformation of the edge member 2 itself. At the same time, the impact transmitted to the end surface 10 of the top plate 1 is also effectively mitigated.

  In addition, as described above, the shock absorbing structure S according to the present embodiment is an upper pressing end that is a continuous pressing end that is in contact with the edge forming surface 21 while the upper end portion 14 and the lower end portion 15 of the edge mounting portion 11 are elastically biased. 24, the lower pressing end 25, and an upper and lower buffer space s1 and a horizontal buffer space s2 which are deformation-permitting spaces formed between the edge mounting portion 11 and the edge member 2.

  Hereinafter, the upper pressing end 24, the lower pressing end 25, the upper and lower buffer spaces s1, and the horizontal buffer space s2 will be described in detail.

  In the state shown in FIG. 4, as described above, the upper pressing end 24 and the lower pressing end 25 are connected to the upper end portion 14 of the edge mounting portion 11 by the elastic repulsive force generated when the insertion protrusion 22 is inserted into the mounting groove 13. In a state where the lower end portion 15 is pressed, the edge forming surface 21 is smoothly continuous with the upper end portion 14 and the lower end portion 15. In this state, as described above, the upper and lower buffer space s1 and the horizontal buffer space s2 are formed by the edge mounting portion 11 and the upper and lower concave portions 26 and the horizontal concave portion 27 provided in the edge member 2.

  On the other hand, FIG.7 and FIG.8 has shown the round part 1r which is the part which the edge part 1e of the top plate 1 made round shape. That is, as shown in the figure, when the edge member 2 is attached to the rounded portion 1r, the edge member 2 becomes a rounded state R curved in a partial arc shape, and the upper pressing end 24 is deformed so that the periphery thereof is thin, while the lower pressing Elastic deformation is performed so that the periphery of the end 25 becomes thick. However, similarly to the straight line state ST shown in FIGS. 3 and 4, the upper pressing end 24 and the lower pressing end 25 elastically bias the upper end portion 14 and the lower end portion 15 of the edge mounting portion 11, respectively, and Since these deformations are allowed by the space s1 and the horizontal buffering space s2, the problem of losing the continuity of the seam between the edge mounting portion 11 and the edge forming surface 21, in other words, the smoothness of the seam, can be preferably avoided. It is a thing.

<Modification>
Further, the round shape formed by the plan view shape of the top plate 1 is not limited to the round portion 1r having the bulge shape in plan view as in the above embodiment. That is, it is a concept including a rounded recess 1r1 formed by curving the edge 1e in a concave shape in plan view.

  That is, as shown in FIGS. 9 and 10, when the edge 1e1 of the top plate 1 is curved into a concave shape in plan view, the edge member is in a rounded concave state R1. That is, while the periphery of the upper pressing end 24 of the edge member 2 corresponding to the inner periphery of the curve is compressed from the extending direction of the edge member 2, the thickness becomes thick, while the pressing end of the edge member 2 corresponding to the outer periphery of the curve Since the periphery of 25 is extended along the extending direction of the edge member 2, it is deformed so as to have a thin cross section.

  However, even in such a state, the upper pressing end 24 and the lower pressing end 25 elastically energize the upper end portion 14 and the lower end portion 15 of the edge mounting portion 11, respectively, as shown in FIG. Since these deformations are allowed by the upper and lower buffer spaces s1 and the horizontal buffer space s2, the problem of losing the continuity of the seam between the edge mounting portion 11 and the edge forming surface 21, in other words, the smoothness of the seam is preferably avoided. It has been obtained.

  By adopting the configuration as described above, the shock absorbing structure S according to the present embodiment is fitted to the edge mounting portion 11 formed at the lower end of the end surface 10 of the edge portion 1e of the top plate 1 and can be elastically deformed. 2 and an edge forming surface 21 that can continue in an obliquely downward direction to the upper end portion 14 and the lower end portion 15 of the edge mounting portion 11, and the upper end portion 14 of the edge mounting portion 11 on the edge forming surface 21 An upper pressing end 24 and a lower pressing end 25 that are continuous ends in contact with the lower end portion 15, a vertical buffering space s 1 and a horizontal buffering space s 2 that constitute a buffering space formed between the edge mounting portion 11 and the edge member 2. It is characterized by having at least.

  With such a configuration, the edge forming surface 21 constituting the so-called ship bottom shape not only has an effect of releasing the impact unique to the ship bottom shape, but also the buffer space, that is, the upper and lower buffer spaces s1 and the horizontal buffer space s2 are appropriately deformed. Therefore, it is possible to effectively relieve the edge member 2 from transmitting the impact directly to the end surface 10 of the top plate 1. By doing so, it is possible to effectively avoid problems such as giving a large impact to the top plate 1 or moving the top plate 1 unexpectedly, and causing the one placed on the top plate 1 to fall down. The problem of causing the top board 1 to collide with other furniture H such as the elbow of the chair can be effectively eliminated.

  The edge portion 1e of the top plate 1 is not limited to the straight portion 1s that is always linear, and may have, for example, a curved shape, that is, a rounded portion 1r or a rounded concave portion 1r1, depending on the plan view shape of the top plate 1. In such a case, even when the edge member 2 is bent, the edge member 2 is pulled toward the outer periphery or the inner periphery, and a compressive force is generated on the inner periphery or the outer periphery. Since the continuous ends are the upper pressing end 24 and the lower pressing end 25 that are the continuous pressing ends that are in contact with the upper end portion 14 and the lower end portion 15 of the edge mounting portion 11 being elastically biased, the edge member 2 and the edge mounting portion 11 are used. Is capable of suitably maintaining a continuous state. In addition, in this embodiment, even if the edge member 2 having a large size is employed by the upper pressing end 24 and the lower pressing end 25 which are such continuous pressing ends, the change in the sectional view shape is suitably buffered space, that is, the upper and lower buffering spaces s1. In addition, since the horizontal buffer space s2 allows, a stable mounting state is realized, and the above-described ship bottom shape can be suitably realized.

  In this embodiment, the edge member 2 is continuously connected to the upper end portion 14 and the lower end portion 15 of the edge mounting portion 11 and the continuous end so that the edge member 2 can be suitably positioned with the edge member 2 mounted. The insertion protrusion 22 is formed as a contact portion that contacts the edge mounting portion 11 in the mounted state.

  Particularly in the present invention, the buffer space has an upper and lower buffer space s1 interposed in the vertical direction between the edge mounting portion 11 and the edge member 2, and a horizontal buffer space s2 interposed in the horizontal direction. The vertical shock absorbing space s1 effectively absorbs the shock that becomes the vertical component force due to the external force, and the horizontal shock absorbing space s2 effectively absorbs the shock that becomes the horizontal component force from any direction from the vertical direction to the horizontal direction. It is possible to effectively absorb the impact.

  And in order to attach the edge member 2 suitably, in this embodiment, while forming the attachment groove | channel 13 which can attach the edge member 2 to the edge attachment part 11, the insertion protrusion 22 which can be inserted in the attachment groove | channel 13 in the edge member 2 is formed. Is provided.

  In order to make the change of the shape of the edge member 2 due to the change of the shape of the edge portion 1e of the top plate 1 inconspicuous, in the present embodiment, the edge forming surface 21 is a bulged surface that is bulged in cross section. In detail, in order to make the edge 1e of the top plate 1 suitable in appearance, the bulging surface is bulged into a partial circle.

  The edge 1e of the top plate 1 is specifically an upper edge member 3 that can cover the side of the top plate 1 from the upper end of the edge 1e of the top plate 1 to the upper end 14 of the edge mounting portion 11. And the lower edge 15 of the upper edge member 3 is connected to the upper pressing end 24 and the lower pressing end so that the upper edge member 3 and the edge member 2 The end face 10 can be effectively protected.

  In the upper edge member 3, as a configuration capable of effectively suppressing deformation of the cross-sectional shape due to the plan view shape of the top plate 1, a straight line in cross-section from the upper edge portion 1 e of the top plate 1 to the upper end portion 14 of the edge mounting portion 11 is used. The upper edge member 3 is formed in a flat plate shape.

  In particular, in this embodiment, the upper edge member 3 is made of a hard material in order to effectively protect the top surface of the top plate 1 from a side impact on the top plate 1 and to maintain the appearance of the top plate 1 suitably. It is a thing.

  The shock absorbing structure S of the top plate 1 edge 1e according to the present invention is applied to the top plate 1 that can move relative to the base that supports the top plate 1 in this embodiment. Even when the top plate 1 collides with another furniture H when the plate 1 is relatively moved, the impact can be effectively absorbed.
