Description

The present invention relates to a folding table with a curtain plate.

Conventionally, a support structure having a grounding portion to the installation surface, a top plate pivotally supported on the support structure around a pivot along the furniture width direction, and at least one of the top plate and the support structure are supported. An interlocking mechanism that displaces the curtain plate downward and closer to the support structure in the furniture depth direction in conjunction with the rotation of the curtain plate and the top plate with respect to the support structure. A folding table with a curtain plate is known.
For example, in Patent Document 1, the top plate side bracket and the curtain plate side bracket are connected at the upper part of the curtain plate, and the lower part of the curtain plate is pivotally supported by the support column by the link stay. Further, a pin as a connecting element is inserted (free-fitted) into both the elongated hole formed in the top plate side bracket and the escape hole formed in the curtain plate side bracket.

JP-A-2015-08425

In the above-mentioned conventional configuration, in the process of reaching the rotation limit of the top plate, the pin is once displaced upward from the bent lower part of the elongated hole of the top plate side bracket, and then returns to the bent lower part again. That is, the curtain plate behaves close to the lower surface of the top plate. Therefore, when the folding work is performed while holding the rear portion of the top plate by hand, there is a concern that the hand is likely to be caught between the lower surface of the top plate and the curtain plate.
Further, although the bent lower part of the elongated hole and the bent upper part of the escape hole are aligned in the width direction, the pin can be further moved relative to each of the two relative moving members, the top plate side bracket and the curtain plate side bracket. It is a relationship that is supported by. Therefore, if the dimensional accuracy at the time of molding or the accuracy at the time of assembling these two members is inconsistent, the pin moves depending on which of the load of the top plate and the curtain plate acts on the pin more. It is conceivable that it becomes difficult or that stress that twists the pin from multiple directions acts by forcibly rotating the top plate.

Therefore, according to the present invention, in a folding table with a curtain plate that links the flip-up of the top plate and the movement of the curtain plate, the load on the mechanical parts that link the top plate and the curtain plate is suppressed, and the movement of the interlocking mechanism is suppressed. The purpose is to make it smooth.

In order to solve the above problems, the folding table with a curtain plate according to the first aspect of the present invention is pivotally supported by the support structure and the top plate rotation axis along the furniture width direction. The top plate hangs below the top plate on the depth side of the fixture in the depth direction of the fixture, and below the top plate rotation shaft, via the curtain plate rotation shaft along the fixture width direction. The top plate is provided with a curtain plate pivotally supported by the support structure and an interlocking mechanism for interlocking the rotation of the top plate and the rotation of the curtain plate. , The curtain plate can be rotated between the flip-up position where the upper surface is raised, and the curtain plate is the depth of the fixture of the top plate when the top plate is in the use position by the operation of the interlocking mechanism. Between the hanging position arranged so as to extend downward on the back side in the direction and the storage position arranged so as to be closer to the support structure than the hanging position when the top plate is in the flip-up position. The interlocking mechanism is fixed to the top plate and can rotate integrally with the top plate, and is fixed to the curtain plate and can rotate integrally with the curtain plate. The top plate side bracket is provided with a curtain plate side bracket, and the top plate side bracket is an interlocking shaft extending in the furniture width direction at the depth side of the furniture depth direction and above the curtain plate rotation shaft. The curtain plate side bracket is provided with a guide recess for engaging the interlocking shaft in the furniture width direction, and the guide recess is the interlocking shaft when viewed from the furniture width direction. The upper surface portion and the lower surface portion extending in the furniture depth direction so as to intersect the rotation locus of the center of the curtain plate rotation axis, and the end portions of the upper surface portion and the lower surface portion on the front side in the furniture depth direction are connected to each other. When the top plate is in the used position, the interlocking shaft is provided with an end face portion that can be brought into contact with the furniture from the back side in the depth direction, and the guide recess is such that the top plate bounces from the used position. It is formed so as to extend in the depth direction of the fixture so that the interlocking shaft can move from the contact position where the interlocking shaft abuts to the end face portion toward the curtain plate rotation shaft side when rotating to the raised position. The guide recess is formed wider in the vertical direction so as to be located closer to the depth side of the fixture in the depth direction than the contact position.

According to this configuration, in a folding table with a curtain plate in which the rotation of the curtain plate is interlocked with the rotation of the top plate, when the top plate in the used position is rotated toward the flip-up position, the interlocking shaft is lowered. And it rotates to the front side in the depth direction of the furniture. Then, the interlocking shaft abuts on the end face portion of the guide recess on the front side in the furniture depth direction, and the curtain plate is rotated toward the front side in the furniture depth direction. Even if the interlocking shaft is separated from the end face portion when the curtain plate is rotated, the upper and lower surface portions extend so as to intersect the rotation locus of the center of the curtain plate rotation shaft of the interlocking shaft. Contact and continue the rotation of the curtain plate. At this time, by moving the interlocking shaft in the guide recess along any of the upper and lower surface portions, the top plate and the curtain plate rotate around two different axes (top plate rotation shaft and curtain plate rotation shaft). Fluctuations in the inter-axis distance in the interlocking mechanism are absorbed. The guide recesses are widened in the vertical direction on the depth side of the fixtures, so that even when the interlocking shaft moves to the depths of the fixtures, mutual interference between the interlocking shafts and the guide recesses is suppressed and relative movement is possible. It's smooth. Further, since the two axes of the top plate rotating shaft and the curtain plate rotating shaft are separated in the vertical direction, the fluctuation of the inter-axis distance in the interlocking mechanism becomes large in the vertical direction, but this fluctuation is also affected by the vertical width of the guide recess. It can be absorbed and the movement of the interlocking mechanism can be smoothed. Since the interlocking shaft is fixed to the top plate side and follows the rotation of the top plate, the accuracy of the relative position between the interlocking shaft and the top plate is ensured to be constant even when the top plate is rotated. Therefore, the relative position accuracy between the operating parts when the top plate is rotated may be particularly ensured between the two parts, the top plate side bracket including the interlocking shaft and the curtain plate side bracket including the guide recess. In this way, after facilitating the setting of the relative position accuracy between the operating parts in the interlocking mechanism, it is possible to smoothly operate the interlocking shaft and prevent overload.

In the above aspect, the curtain plate rotating shaft is supported by the support structure via a moving mechanism that enables vertical movement, and the guide recess is said when the top plate is in the used position. The interlocking shaft may be guided to the contact position by the weight of the curtain plate.
In this case, even if a person or an object hits the curtain plate from the back side in the depth direction of the fixture, the curtain plate moves upward while resisting the urging force due to the weight of the curtain plate, thereby moving to the front side in the depth direction of the fixture. A buffering effect can be obtained. Since the curtain plate rotation shaft can move in the vertical direction, the weight of the entire curtain plate can be used as a urging force vertically downward of the curtain plate, and a cushioning effect can be effectively obtained.

In the above aspect, the upper surface portion and the lower surface portion may be inclined so as to be positioned upward toward the front side in the depth direction of the fixture when the top plate is in the used position.
In this case, since the upper surface portion and the lower surface portion are inclined upward toward the contact position, it is easy to guide the interlocking shaft to the contact position by the weight of the curtain plate, and the curtain plate can be smoothly operated from the start of rotation of the top plate. Can be linked.

In the above aspect, the end face portion may have a curved shape along the outer peripheral surface of the interlocking shaft.
In this case, the end face portion can regulate the movement of the interlocking shaft toward the front side in the furniture depth direction, and also regulate the vertical movement of the interlocking shaft, so that the contact position can be clearly defined in the guide recess. ..

According to the present invention, in a folding table with a curtain plate that links the flip-up of the top plate and the movement of the curtain plate, the load on the mechanical parts that link the top plate and the curtain plate is suppressed, and the movement of the interlocking mechanism is suppressed. Can be smoothed.

The top plate rotating shaft 4 is arranged below the lower surface 2b of the top plate 2. The top plate rotating shaft 4 is arranged behind the front-rear center position of the top plate 2. The top plate 2 is arranged above the pair of pedestals 13 and is supported by the frame 11 in a state of being rotatable about the top plate rotation shaft 4.

The moving mechanism 25 has a curtain plate lower bracket 25a fixed to the front surface 21b of the lower end portion of the curtain plate 21, and a first rotation shaft (curtain plate rotation shaft) whose one end is along the furniture width direction on the curtain plate lower bracket 25a. A lower end link 25b, which is connected so as to be relatively rotatable via 22), is provided. The other end of the lower end link 25b is rotatably connected to the lower part of the pedestal 13 via a second rotation shaft 24 along the furniture width direction. The lower end link 25b extends linearly over, for example, both ends. The moving mechanism 25 supports the lower end of the curtain plate 21 and the curtain plate rotating shaft 22 so as to be able to move up and down with respect to the pedestal 13.

The interlocking mechanism 5 rotates relative to the curtain plate side bracket 6 fixed to the front surface 21b of the upper end portion of the curtain plate 21 and the curtain plate side bracket 6 via the interlocking shaft (connecting shaft) 8 fixed to the tip portion. It includes a top plate side bracket 7 that is movable and is connected so as to be relatively movable.
The curtain plate side bracket 6 includes a base portion 6a fixed to the back surface of the upper end portion of the curtain plate 21, and a connecting portion 6b extending from the base portion 6a to the front side in the furniture depth direction. The connecting portion 6b has a plate shape orthogonal to the furniture width direction, and is formed so that the vertical width is narrowed so as to be located on the front side in the furniture depth direction in a side view. On the front side of the connecting portion 6b in the furniture depth direction, for example, a guide recess 31 that penetrates the portion in the furniture width direction is provided. The guide recess 31 is formed so as to leave the upper and lower portions of the connecting portion 6b on the front side in the furniture depth direction and the three outer peripheral portions on the front side in the furniture depth direction in a frame shape.

The top plate side bracket 7 has a base portion 7a fixed to the lower surface 2b on the depth side of the fixture in the depth direction of the fixture from the top plate rotation shaft 4, and an L-shaped arm extending downward from the base portion 7a in the furniture width direction. A part 7b and the like are provided.

It is provided with a second extending portion 7d that bends downward from the end on the back side, is slightly inclined toward the lower side so as to be located on the back side in the depth direction of the fixture, and extends downward. An interlocking shaft 8 is fixed to the tip end portion (lower end portion) of the second extension portion 7d. The interlocking shaft 8 is arranged on the back side in the depth direction of the fixtures with respect to the top plate rotating shaft 4 and the pedestal 13. The interlocking shaft 8 is arranged below the top plate rotating shaft 4. The interlocking shaft 8 is arranged above the curtain plate rotating shaft 22.

As shown in FIG. 3, the arm portion 7b of the top plate side bracket 7 is formed so as to avoid the cross frame 16 extending between the upper portions of the left and right pedestals 13 when the top plate 2 is in the flip-up position P2. There is. The cross frame 16 has, for example, an elliptical cross section and extends linearly in the furniture width direction. The arm portion 7b is formed so as to extend downward from the back side of the cross frame 16 in the depth direction of the fixture. On the front side of the upper end of the curtain plate 21 in the furniture depth direction, on the front side in the furniture depth direction so as to avoid interference with the bent portion of the arm portion 7b when the top plate 2 rotates (see FIGS. 7 and 8). A cutout portion 21c that cuts out the front surface 21b is provided.

As shown in FIG. 5, the interlocking shaft 8 is arranged on the depth side in the furniture depth direction with respect to the straight line T0 connecting the axes C1 and C3 of the top plate rotating shaft 4 and the curtain plate rotating shaft 22 in a side view. ing. A straight line connecting the axes C1 and C2 of the top plate rotating shaft 4 and the interlocking shaft 8 is indicated by reference numeral T1, and a straight line connecting the axes C2 and C3 of the interlocking shaft 8 and the curtain plate rotating shaft 22 is indicated by reference numeral T2. The straight line connecting the axis lines C3 and C4 of the curtain plate rotation shaft 22 and the second rotation shaft 24 is indicated by reference numeral T3, and the axis lines C1 and C4 of the top plate rotation shaft 4 and the second interlocking shaft 8 are shown. The straight line connecting the above is indicated by reference numeral T4. The top plate 2 (top plate side bracket 3a), the curtain plate 21, the pedestal 13, and the lower end link 25b form a four-bar link mechanism 26 connected along the straight lines T1 to T4. Although the curtain plate 21 is urged downward by its own weight, it is suspended from the top plate 2 via an interlocking shaft 8 that engages with the guide recess 31 to maintain a predetermined arrangement state.

The curtain plate 21 is located on the back side of the pedestal 13 in the depth direction of the fixtures and hangs below the top plate 2. The interlocking shaft 8 is arranged on the front side in the depth direction of the fixture at the upper end of the curtain plate 21. The curtain plate 21 can rotate in conjunction with the rotation of the top plate 2 via the interlocking shaft 8 and thus the interlocking mechanism 5.
The top plate 2 can rotate between the use position P1 (see FIGS. 2 and 5) in which the upper surface 2a is horizontal and the flip-up position P2 (see FIGS. 3 and 9) in which the upper surface 2a is raised. Is.
The curtain plate 21 has a hanging position P3 (see FIGS. 2 and 5) arranged so as to extend downward on the depth side of the furniture depth direction of the top plate 2 when the top plate 2 is in the use position P1, and the top plate 2 Is rotatable between the storage position P4 (see FIGS. 3 and 9), which is arranged so as to be closer to the pedestal 13 than the hanging position P3 when the is in the flip-up position P2.

The interlocking shaft 8 and thus the top plate side bracket 7 are fixed to the top plate 2 and can rotate integrally with the top plate 2.
The curtain plate side bracket 6 and the curtain plate lower bracket 25a are fixed to the curtain plate 21 and can rotate integrally with the curtain plate 21. The first rotation shaft (curtain plate rotation shaft 22) may be fixed to one of the curtain plate side bracket 6 and the curtain plate lower bracket 25a.

The connecting portion 6b of the curtain plate side bracket 6 extends from the back surface side of the curtain plate 21 to the front side in the furniture depth direction in a substantially triangular shape in a side view. The connecting portion 6b of the curtain plate side bracket 6 extends from the back surface side of the curtain plate 21 to the front side in the depth direction of the fixture, and is inclined slightly upward with respect to the horizontal direction. The guide recess 31 formed on the front side of the connecting portion 6b in the depth direction of the fixture has a substantially triangular shape that is slightly smaller than the shape of the connecting portion 6b on the front side of the fixture in the depth direction in a side view.

The guide recess 31 will be described in detail with reference to FIG. In the figure, reference numeral R2 is an arc centered on the axis C3 (axis center) of the curtain plate rotating shaft 22 (an arc along the rotation locus centered on the curtain plate rotating shaft 22 of the curtain plate 21), and the guide recess 31 in the side view Indicates an arc that intersects with. In the figure, reference numeral R1 is an arc centered on the axis C1 (axis center) of the top plate rotating shaft 4 intersecting the guide recess 31 in a side view (arc along the rotation locus of the top plate rotating shaft 4 of the top plate 2). It shows an arc that intersects the guide recess 31 in a side view.

The interlocking shaft 8 is inserted into the guide recess 31 in the furniture width direction, and the interlocking shaft 8 is movably engaged in the guide recess 31. The guide recess 31 is loosely fitted with the interlocking shaft 8 so as to be movable in the furniture depth direction and the vertical direction. The guide recess 31 moves downward with respect to the interlocking shaft 8 due to the weight of the curtain plate 21 when the top plate 2 is in the use position P1. At this time, the interlocking shaft 8 is guided to the specified contact position (engagement position) 31b in the guide recess 31. The guide recess 31 has an inner peripheral surface 31a that can come into contact with the outer peripheral surface 8a of the interlocking shaft 8. The inner peripheral surface 31a has an upper surface portion 32 and a lower surface portion 33 extending in the depth direction of the fixture so as to intersect the arc R2 at the center of the curtain plate rotation shaft 22 in a side view, and an upper surface portion (first guide surface) 32 and a lower surface portion. (Second guide surface) An end surface portion (contact surface, engaging surface) 34 that connects the ends of 33 on the front side in the depth direction of the fixture so that the interlocking shaft 8 can be brought into contact with the back side in the depth direction of the fixture. It has.

"Crossing with the arc R2" means having an angle with respect to the tangent line of the arc R2 in a side view. As a result, the interlocking shaft 8 and the upper surface portion 32 and the lower surface portion 33 are engaged with each other in the rotation direction of the center of the curtain plate rotation shaft 22. As a result, even if the curtain plate 21 unintentionally tries to rotate due to its own weight or the like, the rotation is restricted by any of the upper surface portion 32 and the lower surface portion 33 coming into contact with the interlocking shaft 8. On the back side of the lower surface portion 33 in the depth direction of the fixture, an upward portion 35 that is curved upward and then inclined upward and extends in a straight line is connected. The upward portion 35 defines the relative movement range of the connecting shaft 8 toward the depth side in the furniture depth direction inside the guide recess 31. The upper end portion of the upward portion 35 and the end portion of the upper surface portion 32 on the back side in the depth direction of the fixture are connected to each other via the back side end face portion 36.

As will be described later, the upper surface portion 32 has a linear shape that is inclined so as to be located upward toward the front side in the depth direction of the fixture in the side view. The extension line L1 of the upper surface portion 32 toward the depth side of the fixture in the depth direction and the extension line L2 upward of the upward portion 35 that is inclined upward in the side view form an acute angle when they intersect with each other. The upper surface portion 32 and the upward portion 35 enhance the position regulating force of the connecting shaft 8 in a state of being in contact with and engaged with the back side end surface portion 36 from the front side in the depth direction of the fixture. That is, the interlocking shaft 8 in contact with the back end surface portion 36 is restricted from moving to the back side in the depth direction of the fixture, and the upper surface portion 32 and the upward portion 35 also regulate the movement of the connecting shaft 8 upward and downward. Will be done. It should be noted that a shape in which the inner end portion of the upper surface portion 32 and the upper end portion of the upward portion 35 are directly connected may be adopted.

Within the rotation range of the top plate 2 (the range in which the top plate 2 rotates between the use position P1 and the flip-up position P2), the upper surface portion 32 except when the top plate 2 is near the flip-up position P2. The lower surface portion 33 extends in the furniture depth direction so as to intersect the arc R1 at the center of the top plate rotation shaft 4 in a side view. As a result, when the top plate 2 is rotated, the rotation torque of the top plate 2 can be transmitted from the interlocking shaft 8 to the guide recess 31 and thus to the curtain plate 21. The meaning of "intersecting with the arc R1" is the same as the meaning of "intersecting with the arc R2".

The upper surface portion 32 and the lower surface portion 33 form a straight line inclined in a side view so as to be located upward toward the front side in the depth direction of the fixture. When the curtain plate 21 moves downward due to its own weight, it moves along the inclination of the upper surface portion 32 and the lower surface portion 33 with respect to the interlocking shaft 8. As a result, the interlocking shaft 8 is guided toward the front side in the furniture depth direction along the upper surface portion 32 and the lower surface portion 33, and abuts on the end surface portion 34 to stop. The upper surface portion 32 and the lower surface portion 33 function as guide portions for guiding the interlocking shaft 8 to the contact position 31b. The direction along the upper surface portion 32 corresponds to the length direction of the guide recess 31. The upper surface portion 32 (and the length direction thereof) is substantially parallel to the straight line T1 connecting the axes C1 and C2 of the top plate rotating shaft 4 and the interlocking shaft 8.

The end face portion 34 has a side view arc shape along the outer peripheral surface 8a of the interlocking shaft 8. From the upper and lower ends of the end face portion 34, the upper surface portion 32 and the lower surface portion 33 extend in the tangential direction of the end face portion 34, respectively. As a result, the interlocking shaft 8 guided to the upper surface portion 32 and the lower surface portion 33 is smoothly guided to the position where it abuts on the end surface portion 34 (contact position 31b). The back end surface portion 36 also has a side view arc shape along the outer peripheral surface 8a of the interlocking shaft 8.

The interlocking shaft 8 at the contact position 31b is restricted from moving upward, downward, and toward the front side in the furniture depth direction. The interlocking shaft 8 at the contact position 31b is allowed only to move to the back side in the depth direction of the fixture within the range of the sandwiching angle sandwiched between the upper surface portion 32 and the lower surface portion 33. The curtain plate 21 is suspended from the top plate 2 by bringing the end surface portion 34 of the guide recess 31 into contact with the interlocking shaft 8 by its own weight, and is arranged at the hanging position P3. The end face portion 34 is brought into contact with the interlocking shaft 8 from the back side in the depth direction of the fixture, so that the interlocking shaft 8 hits when the top plate 2 is in the use position P1 (and when the curtain plate 21 is in the hanging position P3). The contact position 31b is defined. The guide recess 31 guides the interlocking shaft 8 to the contact position 31b by the weight of the curtain plate 21 when the top plate 2 is in the use position P1.

The guide recess 31 is formed so as to extend from the contact position 31b to the depth side in the furniture depth direction so that the interlocking shaft 8 can be moved to the back side in the furniture depth direction. In the guide recess 31, "making the interlocking shaft 8 movable" does not mean a movement allowance of about the clearance between the guide recess 31 and the interlocking shaft 8, but a movement allowance of at least about the radius of the interlocking shaft 8, and is preferably interlocked. It means that there is a movement allowance larger than the diameter of the shaft 8. The guide recess 31 has a length that allows the interlocking shaft 8 to move in the furniture depth direction.

The guide recess 31 has a substantially triangular shape with the contact position 31b as the apex on the front side in the depth direction of the fixture in a side view. The guide recess 31 is wider in the vertical direction so as to be located on the depth side in the furniture depth direction so that the interlocking shaft 8 can be moved in the vertical direction on the depth side in the furniture depth direction from the contact position 31b. The guide recess 31 has a length (height) that allows the interlocking shaft 8 to move in the vertical direction. The width of the guide recess 31 in the depth direction of the fixture is larger than the width in the vertical direction.

Next, the operation of the folding table 1 with a curtain plate of the embodiment will be described.
With reference to FIG. 5, when the top plate 2 is in the use position P1, the top plate rotation mechanism 3 is locked, the rotation of the top plate 2 is restricted, and the top plate 2 is fixed to the horizontal use position P1. Will be done. At this time, the curtain plate 21 tries to move downward due to its own weight, but when the end surface portion 34 of the guide recess 31 abuts and engages with the interlocking shaft 8, the curtain plate 21 becomes the interlocking shaft 8 and eventually the top plate 2. It will be in a suspended state. The lower part of the curtain plate 21 can be moved downward by the rotation of the lower end link 25b, but the downward movement of the lower part of the curtain plate 21 is also restricted by suspending the upper part of the curtain plate 21 from the top plate 2. As a result, the curtain plate 21 is maintained in a substantially vertical hanging position P3. A position regulating force due to the weight of the curtain plate 21 acts on the guide recess 31 that engages with the interlocking shaft 8 and thus the upper portion of the curtain plate 21. The interlocking shaft 8 is located at the first position P11 corresponding to the used position P1 of the top plate 2. The first position P11 is a position separated from the top plate rotating shaft 4 and the pedestal 13 in the depth direction of the fixture, and further separated above the curtain plate rotating shaft 22. The first position P11 is a position below the top plate rotation shaft 4 and on the front side in the furniture depth direction with respect to the curtain plate rotation shaft 22.

With reference to FIG. 10, the guide recess 31 is oriented in the length direction in the furniture depth direction, and the interlocking shaft 8 can be moved in the furniture depth direction. When the curtain plate 21 is at the hanging position P3 and the interlocking shaft 8 is at the abutting position 31b, the interlocking shaft 8 can move from the abutting position 31b to the depth side in the furniture depth direction. That is, the guide recess 31 and thus the upper part of the curtain plate 21 can move to the front side in the furniture depth direction with respect to the interlocking shaft 8. When the curtain plate 21 is in the hanging position P3 and a body or an object hits the curtain plate 21 from the outside (depth side in the depth direction), the guide recess 31 moves to the front side in the furniture depth direction with respect to the interlocking shaft 8. At this time, it is necessary to exceed the position regulating force due to its own weight acting on the upper part of the curtain plate 21. Due to this position regulating force, a part of the load toward the front side in the depth direction of the fixture is absorbed, and the impact transmitted to the curtain plate 21 and the collision target is alleviated.

With reference to FIG. 6, when the lock of the top plate 2 is released and the rotation starts from the use position P1 toward the flip-up position P2, the interlocking shaft 8 fixed to the top plate 2 is also integrated with the top plate 2. Rotate. At this time, the interlocking shaft 8 located on the back side and lower side in the furniture depth direction than the top plate rotation shaft 4 is on the front side in the furniture depth direction along the rotation locus of the center of the top plate rotation shaft 4 of the top plate 2. (The side approaching the pedestal 13) and move downward. The interlocking shaft 8 is in contact with the end face portion 34 on the front side of the guide recess 31 in the depth direction of the fixture. In this state, the guide recess 31 and thus the upper portion of the curtain plate 21 are engaged with the interlocking shaft 8 by the weight of the curtain plate 21.

The guide recess 31 moves following the movement of the interlocking shaft 8 due to the weight of the curtain plate 21. When the interlocking shaft 8 moves toward the front side and downward in the furniture depth direction in response to the rotation of the top plate 2, the guide recess 31 and the upper part of the curtain plate 21 also move in the same manner. At this time, the lower portion of the curtain plate 21 moves downward as the lower end link 25b rotates about the center of the second rotation shaft 24. The movement of the curtain plate 21 is regulated by the operation of the four-section link mechanism 26 including the top plate 2, the curtain plate 21, the pedestal 13, and the lower end link 25b. The length of the lower end link 25b is short, which limits the lowering allowance of the curtain plate 21. As a result, at the time of nesting of the table 1, a space for the support legs 14 of the other table 1 to enter below the curtain plate 21 is secured.

With reference to FIG. 5, the interlocking shaft 8 is formed from a straight line T0 connecting the axes C1 and C3 of the top plate rotating shaft 4 and the curtain plate rotating shaft 22 in a side view when the top plate 2 is in the use position P1. It is located on the back side of the furniture in the depth direction. From this state, the interlocking shaft 8 moves so as to approach the straight line T0 by rotating together with the top plate 2 (see FIGS. 6 and 7). After that, the interlocking shaft 8 reaches the straight line T0 (see FIG. 8), and further crosses (crosses) the straight line T0 and rotates toward the front side in the furniture depth direction (see FIG. 9).

With reference to FIG. 9, when the top plate 2 is completely rotated to the flip-up position P2, the interlocking shaft 8 reaches the second position P12 corresponding to the flip-up position P2 of the top plate 2. The second position P12 is a position separated substantially directly below the top plate rotation shaft 4. When the top plate 2 rotates from the flip-up position P2 to the use position P1, the interlocking shaft 8 rotates so as to cross the straight line T0 from the front side to the back side in the furniture depth direction.

With reference to FIG. 7, when the top plate 2 is flipped up, the lower end of the curtain plate 21 hits the trailing edge of the pedestal 13 before the axis C2 (axis center) of the interlocking shaft 8 reaches the straight line T0 in the side view. The rotation of the lower end link 25b is restricted by contact or the like. When the top plate 2 further rotates in the flip-up direction from this state, the inter-axis distance between the interlocking shaft 8 and the curtain plate rotating shaft 22 (the straight line T2 between the interlocking shaft 8 and the curtain plate rotating shaft 22). Length) changes. The inter-axis distance is shortened until the axis C2 of the interlocking shaft 8 reaches the straight line T0 in side view, and extends after the axis C2 of the interlocking shaft 8 crosses the straight line T0. This fluctuation in the distance between the shafts is absorbed by the interlocking shaft 8 moving in the guide recess 31.

When the curtain plate 21 follows the rotation of the top plate 2 and rotates toward the front side in the furniture depth direction to a certain extent, the curtain plate 21 tends to rotate toward the front side in the furniture depth direction due to its own weight. At this time, the interlocking shaft 8 is separated from the contact position 31b downward (in the extension direction of the straight line T1) due to the shortening of the distance between the shafts. Since the lower surface portion 33 in the disengagement direction is inclined downward and the width of the guide recess 31 in the vertical direction is larger than the diameter of the interlocking shaft 8, the downward disengagement of the interlocking shaft 8 is promoted. Will be done. The partially enlarged view of FIG. 7 shows how the interlocking shaft 8 separates from the contact position 31b downward. Then, when the curtain plate 21 is rotated toward the front side in the furniture depth direction by its own weight and the upper surface portion 32 of the guide recess 31 is in contact with the interlocking shaft 8, the upper surface portion of the guide recess 31 is in contact with the interlocking shaft 8. While the 32 is in sliding contact, the curtain plate 21 rotates toward the front side in the furniture depth direction by the length of the guide recess 31. The curtain plate 21 before rotation is shown by the middle chain line in FIG. 7, and the curtain plate 21 after rotation is shown by the solid line in FIG. 7. Due to the rotation of the curtain plate 21, the distance between the upper end of the curtain plate 21 and the lower surface 2b of the top plate 2 is widened, and it becomes easy to prevent the body or an object from being pinched when the top plate 2 is rotated.

FIG. 8 shows a state in which the axis C2 of the interlocking shaft 8 is on the straight line T0 (a state in which the top plate rotating shaft 4, the curtain plate rotating shaft 22, and the three axes of the interlocking shaft 8 are aligned in a straight line). The position of the interlocking shaft 8 when the interlocking shaft 8 is on the straight line T0 is referred to as a straight line position P10. When the distance between the shafts is shortened, the interlocking shaft 8 is separated from the contact position 31b toward the depth side in the furniture depth direction. When the distance between the shafts is extended, the interlocking shaft 8 moves from the back side in the furniture depth direction to the contact position 31b side.

With reference to FIG. 9, when the top plate 2 rotates to the flip-up position P2, the interlocking shaft 8 returns to the contact position 31b in the guide recess 31. At this time, by setting a clearance between the interlocking shaft 8 and the end face portion 34, it is possible to prevent the interlocking shaft 8 and the end face portion 34 from colliding with each other and affecting the rotation positions of the top plate 2 and the curtain plate 21. May be good. When the top plate 2 rotates to the flip-up position P2 and the curtain plate 21 moves to the storage position P4, the rotation of the top plate 2 is locked and the top plate flip-up operation ends.

A case where the front end portion of the guide recess 31 is formed in an acute angle shape in which the upper surface portion 32 and the lower surface portion 33 are extended toward the front side in the depth direction of the fixture and connected to each other will be described. In this case, since the guide recess 31 extends further toward the front side in the furniture depth direction, it becomes wider in the furniture depth direction, whereby the connecting portion 6b also becomes wider in the furniture depth direction. On the other hand, in the embodiment, since the upper surface portion 32 and the lower surface portion 33 are connected by the arcuate end surface portion 34, the width of the connecting portion 6b in the furniture depth direction is suppressed. As a result, even when the top plate 2 is rotated to the flip-up position P2, the width of the connecting portion 6b in the fixture depth direction is set so that the connecting portion 6b does not protrude toward the front side in the fixture depth direction from the pedestal 13. be able to. As a result, when nesting a plurality of folding tables 1 with a curtain plate, the end portion of the connecting portion 6b on the front side in the furniture depth direction is adjacent to the folding table 1 with a curtain plate on the front side in the furniture depth direction. It is possible to prevent the top plate 2 from coming into contact with the top plate 2.

Since the distance between the shafts is oriented in the vertical direction, the interlocking shaft 8 separated from the contact position 31b moves downward as the distance between the shafts is shortened. On the other hand, since the guide recess 31 is formed so that the depth side of the fixture in the depth direction expands in the vertical direction, the interlocking shaft 8 separated from the contact position 31b can easily move downward. For example, the lower surface portion 33 of the guide recess 31 is in sliding contact with the downwardly moved interlocking shaft 8, so that the rotation of the upper portion of the curtain plate 21 is guided.

The guide recess 31 has an angle (for example, an angle of less than 45 degrees with respect to the horizontal direction) in the length direction along the upper surface portion 32 while the curtain plate 21 rotates between the hanging position P3 and the storage position P4. It is set to be. Therefore, if the guide recess 31 is formed with a constant vertical width, the load component that the downwardly moved interlocking shaft 8 presses the lower surface portion 33 downward becomes large. Then, it becomes difficult for the interlocking shaft 8 and the lower surface portion 33 to slide, and it becomes difficult for the guide recess 31 to guide the rotation of the curtain plate 21. On the other hand, since the guide recess 31 has a tapered shape having a wider vertical width toward the depth side in the furniture depth direction, the interlocking shaft 8 can be brought into contact with the lower surface portion 33 in an inclined manner. As a result, the sliding of the interlocking shaft 8 and the lower surface portion 33 becomes smooth, and it becomes easy to guide the rotation of the curtain plate 21.

Further, since the length direction of the guide recess 31 is set to be closer to the horizontal, the guide recess 31 and the upper part of the curtain plate 21 can be smoothly moved in the furniture depth direction. As a result, even if a body or an object is sandwiched between the curtain plate 21 and the top plate 2, the sandwiching load on the body or the object is reduced.
Further, the upper surface portion 32 of the guide recess 31 has a linear shape having an angle so as to be horizontal when the curtain plate 21 is in the storage position P4 (see FIG. 9). When the folding table 1 with a curtain plate in which the top plate 2 is rotated to the flip-up position P2 is moved on the floor surface F, for example, when the caster 15 tries to get over the step, it is caused by the impact at that time. The curtain plate 21 may wobble due to the load. This wobbling is mainly the rotation around the curtain plate rotation shaft 22 of the curtain plate 21, but since the upper surface portion 32 is a horizontal linear shape, the rotation of the curtain plate 21 around the curtain plate rotation shaft 22. Can be regulated. The upper surface portion 32 may be inclined so that the rear portion (back side in the depth direction) faces downward while the curtain plate 21 is in the storage position P4.
Further, for example, when a body or an object is sandwiched between the curtain plate 21 and the pedestal 13, the lower end link 25b can rotate upward against the urging force due to the weight of the curtain plate 21. As a result, even if a body or an object is sandwiched between the curtain plate 21 and the pedestal 13, the sandwiching load on the body or the object is reduced.
Further, when a body or an object hits the curtain plate 21 from the outside (depth side in the depth direction), the curtain plate 21 moves to the front side in the furniture depth direction against the position restricting force due to the weight of the curtain plate 21. As a result, the impact transmitted to the curtain plate 21 and the collision target is alleviated.

In the embodiment, the guide recess 31 is formed so as to extend in the furniture depth direction, and the guide recess 31 is formed so that the back side of the guide recess 31 in the furniture width direction extends in the vertical direction. As a result, the movement of the interlocking shaft 8 corresponding to the expansion and contraction of the distance between the shafts is allowed, the sliding contact between the interlocking shaft 8 and the guide recess 31 becomes smooth, and the pinching of the body or an object in front of or behind the curtain plate 21 is suppressed. , A cushioning action is obtained when a body or an object collides with the curtain plate 21.

When the curtain plate 21 rotates toward the front side in the furniture depth direction to a certain extent following the rotation of the top plate 2, the position of the center of gravity moves to the front side in the furniture depth direction with respect to the curtain plate rotation shaft 22. In this case, a moment is generated on the curtain plate 21 toward the front side in the depth direction of the fixture due to its own weight. Then, a load due to the moment is applied to the interlocking shaft 8 from the guide recess 31. This load acts to assist the rotation of the top plate 2 via the interlocking shaft 8. As a result, the operating force of the top plate when the top plate 2 approaches the flip-up position P2 can be reduced.

Since the interlocking shaft 8 is fixed to the top plate 2 side and follows the rotation of the top plate 2, the accuracy of the relative position between the interlocking shaft 8 and the top plate 2 is ensured to be constant even when the top plate rotates. .. Therefore, the relative position accuracy between the operating parts when the top plate is rotated may be particularly ensured between the two parts of the top plate side bracket 7 including the interlocking shaft 8 and the curtain plate side bracket 6 including the guide recess 31. In this way, after facilitating the setting of the relative position accuracy between the operating parts in the interlocking mechanism 5, it is possible to ensure smooth operation of the interlocking shaft 8 and prevention of overload.

Even when the top plate 2 is in the flip-up position P2, the top plate rotation mechanism 3 is locked, the rotation of the top plate 2 is restricted, and the top plate 2 is fixed at the upright flip-up position P2. At this time, the curtain plate 21 is in a storage position P4 substantially parallel to the pedestal 13, the upper portion is suspended from the top plate 2 via the interlocking shaft 8, and the lower portion is suspended from the pedestal 13 via the lower end link 25b. It will be in the state of being.

With reference to FIGS. 8 and 9, when the top plate 2 is unlocked and starts to rotate from the flip-up position P2 toward the use position P1, the top plate 2 is moved to the second position P12 substantially directly below the rotation shaft 4. A certain interlocking shaft 8 moves to the back side in the furniture depth direction along the rotation locus of the center of the top plate rotation shaft 4 of the top plate 2. At this time, the interlocking shaft 8 temporarily moves in the guide recess 31 from the contact position 31b to the back side in the furniture depth direction until it reaches the position P10 on the straight line. When the rotation locus of the center of the top plate rotation shaft 4 turns upward, the interlocking shaft 8 engages with the upper surface portion 32 of the guide recess 31, and pulls up the guide recess 31 and the upper part of the curtain plate 21 upward. Initially, the curtain plate 21 rotates about the center of the curtain plate rotation shaft 22 toward the depth side in the furniture depth direction. When the rotation of the top plate 2 progresses and the inter-axis distance between the interlocking shaft 8 and the curtain plate rotating shaft 22 is shortened and then begins to extend, the interlocking shaft 8 reaches the contact position 31b at the guide recess 31. It returns and comes into contact with the end face portion 34. When the top plate 2 further rotates in this state, the curtain plate 21 starts to rise while operating the four-node link mechanism 26. When the top plate 2 rotates to the used position P1 and the curtain plate 21 moves to the hanging position P3, the rotation of the top plate 2 is locked and the top plate unfolding operation ends.

As described above, the folding table 1 with a curtain plate of the present embodiment is arranged above the pedestal 13 extending in the vertical direction in the frame 11 and the pedestal 13, and the top plate rotates along the furniture width direction. The top plate 2 pivotally supported by the pedestal 13 via the shaft 4 and the top plate 2 hanging below the top plate 2 on the back side in the furniture depth direction from the pedestal 13 and more than the top plate rotation shaft 4. Below, the curtain plate 21 pivotally supported by the pedestal 13 via the curtain plate rotation shaft 22 along the furniture width direction, and the rotation of the top plate 2 and the rotation of the curtain plate 21 are linked. It is equipped with an interlocking mechanism 5. The top plate 2 is rotatable between a use position P1 in which the upper surface 2a is horizontal and a flip-up position P2 in which the upper surface 2a is raised. The curtain plate 21 has a hanging position P3 which is arranged so as to extend downward on the depth side of the fixture depth of the top plate 2 when the top plate 2 is in the use position P1 by the operation of the interlocking mechanism 5. When the top plate 2 is in the flip-up position P2, it can rotate between the storage position P4, which is arranged so as to be closer to the pedestal 13 than the hanging position P3. The interlocking mechanism 5 includes a top plate side bracket 7 fixed to the top plate 2 and integrally rotatable, and a curtain plate side bracket 6 fixed to the curtain plate 21 and integrally rotatable. .. The top plate side bracket 7 integrally supports an interlocking shaft 8 extending in the furniture width direction on the back side of the top plate rotation shaft 4 in the furniture depth direction and above the curtain plate rotation shaft 22. .. The curtain plate side bracket 6 includes a guide recess 31 for inserting and engaging the interlocking shaft 8 in the furniture width direction. When viewed from the furniture width direction, the guide recess 31 includes an upper surface portion 32 and a lower surface portion 33 extending in the furniture depth direction so as to intersect the rotation locus of the center of the curtain plate rotation shaft 22 of the interlocking shaft 8. The upper surface portion 32 and the lower surface portion 33 on the front side in the furniture depth direction are connected to each other, and the interlocking shaft 8 can abut from the furniture depth direction back side when the top plate 2 is in the use position P1. It includes an end face portion 34. The guide recess 31 rotates the curtain plate from the contact position 31b where the interlocking shaft 8 abuts on the end face portion 34 when the top plate 2 rotates from the use position P1 to the flip-up position P2. It is formed so as to extend toward the depth side in the depth direction of the fixture so that it can be moved toward the shaft 22 side. The guide recess 31 is formed so wide in the vertical direction that it is located closer to the depth side of the fixture in the depth direction than the contact position 31b.

According to this configuration, in the folding table 1 with a curtain plate in which the rotation of the curtain plate 21 is interlocked with the rotation of the top plate 2, the top plate 2 at the use position P1 is rotated toward the flip-up position P2. Then, the interlocking shaft 8 rotates downward and toward the front side in the furniture depth direction. Then, the interlocking shaft 8 abuts on the end surface portion 34 of the guide recess 31 on the front side in the furniture depth direction, and the curtain plate 21 is rotated toward the front side in the furniture depth direction. Even if the interlocking shaft 8 is separated from the end face portion 34 when the curtain plate 21 is rotated, the upper and lower surface portions 32 and 33 extend so as to intersect the rotation locus of the center of the curtain plate rotation shaft 22 of the interlocking shaft 8. The shaft 8 comes into contact with any of the upper and lower surface portions 32 and 33 to continue the rotation of the curtain plate 21. At this time, the interlocking shaft 8 moves in the guide recess 31 along any of the upper and lower surface portions 32 and 33, so that the interlocking shaft 8 rotates around two different axes (top plate rotating shaft 4 and curtain plate rotating shaft 22). The fluctuation of the distance between the axes in the interlocking mechanism 5 between the moving top plate 2 and the curtain plate 21 is absorbed. As a result, even if a person or an object collides with the curtain plate 21 from the depth direction of the fixture, the curtain plate 21 moves upward and moves to the front side in the depth direction of the fixture against the urging force of the curtain plate 21 by its own weight. Therefore, a buffering effect can be obtained. Further, since the guide recess 31 is widened in the vertical direction on the depth side in the furniture depth direction, the interlocking shaft 8 and the guide recess 31 are also moved to the front side in the furniture depth direction with respect to the interlocking shaft 8. Mutual interference is suppressed and relative movement is smooth. Further, since the two axes of the top plate rotating shaft 4 and the curtain plate rotating shaft 22 are separated in the vertical direction, the fluctuation of the inter-axis distance in the interlocking mechanism 5 becomes large in the vertical direction, but this fluctuation is caused by the guide recess 31. It can also be absorbed depending on the vertical width, and the movement of the interlocking mechanism 5 can be smoothed.

In the folding table 1 with a curtain plate of the present embodiment, the curtain plate rotating shaft 22 is supported by the pedestal 13 via a moving mechanism 25 that enables vertical movement, and the guide recess 31 is When the top plate 2 is in the use position P1, the interlocking shaft 8 is guided to the contact position 31b by the weight of the curtain plate 21.
In this case, even if a person or an object collides with the curtain plate 21 from the depth direction of the fixture, the curtain plate 21 moves upward and moves to the front side in the depth direction of the fixture against the urging force due to the weight of the curtain plate 21. Therefore, a buffering effect can be obtained. Since the curtain plate rotating shaft 22 can move in the vertical direction, the weight of the entire curtain plate 21 can be used as a urging force vertically downward of the curtain plate 21, and a cushioning effect can be effectively obtained.

In the folding table 1 with a curtain plate of the present embodiment, the upper surface portion 32 and the lower surface portion 33 are inclined so as to be positioned upward toward the front side in the furniture depth direction when the top plate 2 is in the use position P1. There is.
In this case, since the upper surface portion 32 and the lower surface portion 33 are inclined upward toward the contact position 31b, the interlocking shaft 8 can be easily guided to the contact position 31b by the weight of the curtain plate 21, and the top plate 2 rotates. The curtain plate 21 can be smoothly interlocked from the beginning.

In the folding table 1 with a curtain plate of the present embodiment, the end surface portion 34 has a curved shape along the outer peripheral surface 8a of the interlocking shaft 8.
In this case, the end face portion 34 regulates the movement of the interlocking shaft 8 toward the front side in the furniture depth direction, and also regulates the vertical movement of the interlocking shaft 8, so that the contact position 31b in the guide recess 31 is clearly defined. Can be specified.

The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, the guide recess 31 has the form of a through hole that penetrates the connecting portion 6b of the curtain plate side bracket 6 in the fixture width direction, but is not limited to this. The guide recess 31 may be a bottomed recess with one side closed in the furniture width direction.

As shown in FIG. 11, the guide recess 31 may form a recess 37 in which the upper end portion of the interlocking shaft 8 can be inserted by recessing the upper surface portion 32 upward above the contact position 31b. Good. When the curtain plate 21 is in the hanging position P3 or the storage position P4 and the interlocking shaft 8 is in the contact position 31b, the interlocking shaft 8 can move from the contact position 31b to the back side in the furniture depth direction. On the other hand, by forming an arc-shaped recess 37 that matches the upper end of the connecting portion 8 above the contact position 31b, the following effects can be obtained. That is, the weight of the curtain plate 21 prevents the connecting shaft 8 from being fitted into the recess 37, and the interlocking shaft 8 being prevented from moving along the upper surface portion 32 toward the back side in the furniture depth direction. As a result, the position regulating force for keeping the interlocking shaft 8 at the contact position 31b is strengthened by the weight of the curtain plate 21, so that when the curtain plate 21 is at the hanging position P3 (FIG. 11 (a)), the curtain plate 21 It is possible to enhance the cushioning effect when a person or an object collides. When the curtain plate 21 is in the storage position P4 (FIG. 11B), the rattling of the curtain plate 21 can be suppressed even when the folding table 1 with the curtain plate is moved.
The configuration in the above embodiment is an example of the present invention, and various modifications can be made without departing from the gist of the present invention, such as replacing the constituent elements of the embodiment with well-known constituent elements.
