Description

  The present invention relates to storage furniture provided with a drawer.

Conventionally, storage furniture provided with means for automatically retracting the drawer, which can be moved relative to the storage furniture body between the closed position and the open position, from the open position to the closed position. Is considered. For example, although what is shown in the following patent document 1 is related to a freezer, as shown in FIG. 1 and FIG. 2 etc. of the same document, it is inclined at the back (rear) end of the rail provided on the side surface of the freezer body. A roller that rolls on the rail is provided on the side surface of the drawer that is slidable relative to the freezer body, and the roller is moved along the inclined portion during the operation of moving the drawer from the open position to the closed position. By rolling, the drawer can be automatically retracted to the closed position.
Japanese Utility Model Publication No. 5-41349 (see FIGS. 1 and 2)

  However, since the rail provided in the freezer main body constitutes the support mechanism itself that guides the sliding movement of the drawer, the above-described aspect is provided, for example, as a support mechanism in the fixed portion provided in the freezer main body and the drawer. When a suspension rail mechanism that horizontally moves the drawer between the open position and the closed position by relative movement with the movable part is adopted, the inclined part cannot be formed in the fixed part, and the versatility is inferior. is there.

  On the other hand, apart from the support mechanism, a means for automatically pulling the drawer into the closed position is provided, and magnetic bodies (magnets, etc.) that can be magnetically attached to the back part of the storage furniture body and the back part of the drawer are respectively provided. Provide a mode in which a drawer located immediately before the closing position is drawn into the closing position by using the attractive force between these magnetic bodies, or a latch body in which an engagement groove is formed on the back surface of the storage furniture body in the vertical plane And an engaging element that can be engaged with the engaging groove is provided on the back surface of the drawer. When the drawer is moved immediately before the closing position, the engaging element becomes the engaging groove. The latch body is associated with the latching operation in which the latch body pulls the engagement element into the engagement groove by a predetermined urging means in response to the sliding contact, and generates a force for pulling the drawer to the closed position. Conceivable.

  However, in both the mode using the attractive force of the magnetic material and the mode using the latch operation, a force that pulls the drawer to the closed position is generated only when the drawer is moved from the open position to just before the closed position. The range in which the drawer can be automatically retracted to the closed position is extremely small, and in the end, an operation force that is almost the same as the operation force that pushes the drawer to the closed position is required, and the drawer is pushed all the way to the closed position. When an operation force lighter than the operation force is applied, there arises a problem that the drawer cannot be moved to the closed position.

  The present invention has been made paying attention to such a problem, and its main purpose is to be versatile and to effectively obtain a range in which the drawer can be automatically retracted to the closed position, thereby reducing the light operation force. It is an object of the present invention to provide storage furniture that can reliably move the drawer to the closed position.

  That is, the storage furniture of the present invention comprises a storage furniture main body and a drawer that can move relative to the storage furniture main body between a closed position and an open position. A support mechanism that supports the drawer so that it can move horizontally between the closed position and the open position; and a pull-in motion induction that continuously generates a force in a direction in which the drawer is pulled into the closed position in a predetermined region. A retraction mechanism having a portion, the retraction mechanism including a guide portion and an actuator that moves along the guide portion, and along the retraction operation inducing portion provided in the guide portion. The drawer is pulled into the closed position by moving the operating element.

  Here, the retracting action inducing part is provided in a predetermined area of the guide part, and may be provided in a part of the guide part or provided in the entire area of the guide part. Further, the guide portion may be either one that can be in surface contact with the actuator or one that can be in line contact.

  In such a case, since a retracting mechanism is provided separately from the support mechanism, it is possible to select and apply a normal slide rail mechanism or suspension rail mechanism as the support mechanism, and easily change the specifications. It can also be versatile. In addition, when the formation region of the pulling motion inducing portion occupying the guide portion is set large, by moving the operating element along the pulling motion inducing portion, the drawer at a position relatively far from the closed position can be used. The force that pulls into the closed position acts. As a result, a range in which the drawer can be automatically pulled into the closed position can be effectively obtained, and the drawer can be reliably moved from the open position to the closed position with a light operating force.

  Thus, the storage furniture according to the present invention automatically sets the drawer to the closed position by appropriately setting the formation region of the pulling action inducing portion and the shape of the pulling action inducing portion occupying the guide portion according to the usage mode and the like. Therefore, it is possible to easily adjust the distance to be drawn, and it is excellent in practicality. The movement of the actuator along the guide portion may be either an aspect using the weight of the actuator itself or an aspect using an urging means described later.

  In particular, the retracting mechanism includes a horizontal portion and an inclined portion that functions as a retracting action inducing portion that are provided on either the storage furniture main body or the drawer and extend along the depth direction thereof. The rail, the actuator provided on the other side so as to be movable up and down and capable of elastically contacting the guide portion, and a biasing means for biasing the actuator in the direction of elastically contacting the guide portion. In this case, the actuator can be moved in a state where it is reliably brought into contact with the guide portion by the urging means, and the retracting motion inducing portion can be realized in a simple shape. Then, by using the urging force of the urging means to move the operating element along the inclined portion, it becomes possible to smoothly and accurately perform the drawing operation of the drawer to the closed position.

  In order to move the actuator along the guide portion more smoothly, it is preferable that the guide portion is substantially flat. Here, the “substantially flat shape” does not mean that the guide portion is flat with respect to the extending direction (horizontal direction), in other words, the guide portion has no step or inclination, but the surface of the guide portion. It means that it is flat. That is, when the guide portion is provided with an inclined portion as a pull-in operation inducing portion, the surface of the inclined portion itself is flat, and when the guide portion is provided with a horizontal portion, the surface of the horizontal portion itself is flat. It means that.

  On the other hand, the guide portion has a rack shape having a plurality of first tooth portions at a predetermined pitch, and the operating member has a second tooth portion engageable with the first tooth portion at a predetermined pitch on an outer peripheral surface. In the case of the pinion provided in the above, the actuator pinion moves accurately along the guide portion by moving the second tooth portion along the guide portion while meshing the second tooth portion with the first tooth portion. Can do.

  In this case, the rail is provided on either the side surface portion of the storage furniture main body or the side surface portion of the drawer, and the operating element is provided on the other side, and a rod that connects the operating elements in a synchronously rotatable manner is provided as the operating element. By interposing it in between, the pinion as the actuator is synchronized via the rod, so that even a drawer with a large width does not displace in the horizontal turning direction from the initial setting position during movement, and is stable and smooth. Movement of the drawer can be ensured.

  As a specific embodiment, the urging means includes an arm portion having a rotating end at both ends and the operating element at one rotating end, and the other rotating end of the arm portion. There may be mentioned one constituted by a spring attached with one end and biased in a direction in which the actuator is elastically contacted with the guide.

  In order to bring the actuator into elastic contact with the guide portion, the upper surface portion of the rail functions as the guide portion, and the urging means urges the actuator in the direction of pressing the operator downward. That's fine.

  In particular, if the operating element is a rolling element that can roll along the guide portion, smooth movement of the operating element can be realized.

  In order to make the movement of the actuator along the guide portion more stable, the guide portion may be a guide surface portion that can come into surface contact with the actuator.

  Further, when the retracting action inducing portion is provided on either the back end side of the storage furniture body or the back end side of the drawer, and the operating element is provided on the other side, the pulling operation to the closed position of the drawer is performed. Can be performed more reliably.

  The pull-in mechanism has a horizontal portion and an inclined portion that functions as a pull-in motion inducing portion continuously in the guide portion that is provided in either the storage furniture main body or the drawer and extends along the depth direction thereof. If the rail and the actuator provided on the other side so as to be movable up and down and can be brought into contact with the guide portion by its own weight, there is no need to provide a biasing means, and the number of parts can be reduced and the structure can be reduced. Contributes to simplification.

  A base that can be attached to either the storage furniture body or the drawer; an arm that is pivotally attached to the base and has pivot ends at both ends; and one pivot end of the arm portion. If the actuator and the spring provided between the other rotation end of the arm portion and the base and biasing the actuator in the direction of elastically contacting the guide portion are unitized, By simply attaching the storage unit to the storage furniture body or the drawer, the arm part, the actuator, and the spring can be provided to the storage furniture body or the drawer via the base, thereby improving the efficiency of the assembly work. Contribute to The arm portion and the spring constitute urging means, and the above configuration is simply described as that the base, the actuator and the urging means are unitized.

  Further, the base is provided on a side surface portion of the drawer, and the base is brought into contact with a part of the storage furniture body when the drawer is moved from the closed position to the open position. If a stopper portion for restricting movement in the same direction is provided, it is possible to reliably prevent the drawer from coming out of the storage furniture body. In addition, since the stopper portion is provided on the base that pivotally supports the arm portion, it is possible to effectively reduce the number of parts and simplify the structure as compared with a mode in which a dedicated stopper portion is separately provided.

  As a preferred embodiment, the arm portion and the base are each formed from a single thin plate-like material, and the base can be attached to the side surface portion of the drawer, and the base An extension portion extending in a direction orthogonal to the base body from a predetermined portion of the main body, and a spring attachment portion to which one end of the spring can be attached to the extension portion; and the spring attachment portion Further, there may be mentioned those provided with the stopper portion located farther from the base body. In such a case, since the arm portion and the base are each formed from a single material, the number of unnecessary parts is not increased, and the stopper portion is more than the spring mounting portion. Since it is provided at a position away from the base body, when the stopper part comes into contact with a part of the storage furniture body, the arm part or the spring does not come into contact with a part of the storage furniture body, so that it has a good stopper action. Can be secured.

  As described above, according to the present invention, since the retracting mechanism is provided separately from the support mechanism, it is possible to appropriately select and apply a normal slide rail mechanism or suspension rail mechanism as the support mechanism. Generality can be imparted. In addition, by setting a large area of the pulling action inducing section in the guide section, by moving the actuator along the pulling action inducing section, the drawer is relatively far from the closed position. A pulling force acts on the closed position, and a range in which the drawer can be pulled can be effectively earned, and the pulling operation of the drawer can be reliably performed with a light operation force.

Specifically, the base main body B1 is attached to the outward surface of the side surface portion 41 of the drawer 4 in a posture in which the back extension portion B12 protrudes from the back surface portion 42 of the drawer 4 to the back (backward), and a predetermined location. Are fixed to the side surface portion 41 of the drawer 4 by welding or screwing or the like, so that the unitized base B, the biasing means 9 and the rolling element 8 are attached to the outward surfaces of the side surface portions 41 of the drawer 4. And in this attachment state, it sets so that the rolling element 8 may elastically contact with the guide surface part 7a of the rail 7. FIG.

  As described above, the support mechanism 5 and the retracting mechanism 6 are provided between the side surface portion 21 of the storage furniture body 2 and the side surface portion 41 of the drawer 4. In the present embodiment, the support mechanism 5 and the retracting mechanism 6 are provided along the height direction of the storage furniture 1, and the retracting mechanism 6 is provided at a position relatively lower than the support mechanism 5.

  Further, in the present embodiment, a rack R having a plurality of tooth portions formed at a predetermined pitch on the upper surface portion is provided on the outward surface of the side surface portions 21 of the storage furniture body 2 and further below the rail 7. The pinions P having tooth portions engageable with the tooth portions of each rack R on the outer periphery are provided on both side surface portions 41 of the drawer 4 using brackets or the like. The pinion P is provided below the bottom surface portion 43 of the drawer 4 via a bracket or the like. Then, by connecting these pinions P with rods, the pinions P can rotate synchronously in accordance with the movement of the drawer 4.

  Next, with reference to FIGS. 2 to 5, the usage of the drawer 4 and the operation of the retracting mechanism 5 will be described with respect to the storage furniture 1 having such a configuration.

  In order to move the drawer 4 in the closed position (4x) to the open position (4y), an operation force is applied by pulling the handle 44a provided at the upper end of the end plate 44 of the drawer 4 to the front. To do. By this operation, the drawer 4 horizontally moves forward using the support mechanism 5, and with the horizontal movement of the drawer 4, the rolling element 8 is urged in the direction (downward) pressed by the urging means 9. Then, the rail 7 is rotated in a state of being elastically contacted sequentially with the inclined portion 72 and the horizontal portion 71 of the rail 7. In addition, when the rolling contact object 8 is moved from the inclined part 72 to the horizontal part 71, the height position of the rolling element 8 is gradually displaced upward, and the upward movement of the rolling element 8 causes the arm part 91 to move to the shaft hole. With the support shaft A inserted into 91c as a fulcrum, the other rotation end 91b (the rotation end to which one end of the spring 92 is attached) is rotated in a direction to move away from the attachment hole B211 against the biasing force of the spring 92. Move. Then, in a state where the object to be elastically contacted by the rolling element 8 has completely shifted from the inclined portion 72 to the horizontal portion 71, the arm portion 91 makes the longitudinal direction of the first arm substantially parallel to the longitudinal direction of the horizontal portion 71. Take a posture. When the drawer 4 is moved to the open position, the stopper portion B212 provided on the base B comes into contact with the contact portion T provided in the vicinity of the front edge portion on the inward surface of the side surface portion 21 of the storage furniture body 2. This prohibits further movement of the drawer 4 in the same direction (see FIG. 4). In the present embodiment, the attachment location of the contact portion T is appropriately set so that the contact portion T does not contact the arm portion 91 before contacting the stopper portion B212. Further, by providing an elastically deforming portion such as rubber at both or one of the contact portions of the stopper portion B212 and the contact portion T, impact force and impact at the time of contact between the stopper portion B212 and the contact portion T are provided. Sound can be reduced effectively.

  On the other hand, the drawer 4 in the open position (4y) is moved to the closed position (4x) by applying an operation force that pushes the drawer 4 back. By this operation, the drawer 4 horizontally moves backward (backward) using the support mechanism 5, and with the horizontal movement of the drawer 4, the horizontal portion 71 is in a state where the rolling element 8 is in elastic contact with the horizontal portion 71. To the back (backward). Then, when the drawer 4 is moved to a depth to some extent (in this embodiment, when about three-quarters of the drawer 4 is accommodated in the second storage space 2S), the rolling element 8 has the horizontal portion 71 and the inclined portion 72. (See FIG. 5), and the object that is elastically contacted across the boundary portion moves from the horizontal portion 71 to the inclined portion 72, whereby the rolling element 8 is moved to the biasing means 9 (spring 92). It moves while rotating along the inclined part 72 in a state where it is urged so as to be elastically contacted with the inclined part 72 by the urging force (elastic return force). As the rolling element 8 moves along the inclined portion 72, the height position of the rolling element 8 is gradually displaced downward, and the arm 91 is inserted into the shaft hole 91c by the downward movement of the rolling element 8. Using the axis A as a fulcrum, the other rotation end 91b (the rotation end to which one end of the spring 92 is attached) is rotated in a direction approaching the attachment hole B211. As a result, the biasing force of the spring 92 is utilized. Thus, the rotational force of the rolling element 8 that moves along the inclined part 72 while elastically contacting the inclined part 72 becomes larger than the rotational force of the rolling element 8 that moves along the horizontal part 71, and the closed position with respect to the drawer 4. The force in the direction of (4x) y is continuously generated, and the drawer 4 automatically moves to the closing position (4x) y.

  Since the pinion P can rotate on the rack R in synchronization with the movement of the drawer 4 between the closed position (4x) and the open position (4y), the drawer 4 can be inserted and removed accurately and smoothly. Can be done. There is no moment in the horizontal turning direction acting on the entire drawer 4, and the drawer 4 can be moved without difficulty.

  As described above, the storage furniture 1 according to this embodiment includes the support mechanism 5 that supports the drawer 4 with respect to the storage furniture body 2 so as to be horizontally movable between the closed position (4x) and the open position (4y), and the drawer. 4 is provided separately from the retracting mechanism 6 having the inclined portion 72 as the retracting action inducing portion of the present invention that continuously generates force in the direction toward the closing position (4x) with respect to 4 in a predetermined region. 5, a suspension rail mechanism can be applied, and the retracting mechanism 6 includes a rail 7 having a guide surface portion 7a and a rolling element 8 that moves while adjoining the guide surface portion 7a, and is provided on the guide surface portion 7a. Since the drawer 4 is pulled into the closed position (4x) by moving the rolling element 8 along the inclined portion 72, the area of the inclined portion 72 in the guide surface portion 7a of the rail 7 is increased. By ku setting, the force of pulling the closed position closed position relative to the drawer 4 in a position relatively distant from (4x) (4x) it acts, it is possible to make effective the range that can pull the drawer 4. As a result, the drawer 4 can be moved from the open position (4y) to the closed position (4x) with a light operating force as compared with the conventional one, and the drawer 4 can be reliably pulled.

  In particular, the pull-in mechanism 6 can be moved up and down on the drawer 4 provided on the storage furniture body 2 and having a horizontal portion 71 and an inclined portion 72 continuously on a guide surface portion 7 a extending along the depth direction thereof, and the drawer 4. And the urging means 9 for urging the rolling element 8 in a direction in which the rolling element 8 is brought into elastic contact with the guide surface portion 7a. 9, the rolling element 8 can be moved in a state in which the rolling element 8 is reliably brought into contact (pressed) with the guide surface portion 7a, and the drawing operation of the drawer 4 to the closed position (4x) can be performed stably and accurately.

  Moreover, since the horizontal part 71 and the inclined part 72 which comprise the guide surface part 7a are made into substantially flat shape, respectively, the movement of the rolling element 8 along the guide surface part 7a can be performed more smoothly.

  The urging means 9 includes an arm portion 91 having a rotation end at both ends and a rolling element 8 provided at one rotation end 91a, and one end portion attached to the other rotation end 91b of the arm portion 91; Since the rolling element 8 is composed of a spring 92 that urges the rolling element 8 in the direction of elastic contact with the guide surface portion 7a, the structure of the urging means 9 is simplified, and the stable elastic force of the rolling element 8 with respect to the guide surface portion 7a is achieved. The contact state can be maintained.

  In particular, since the upper surface portion of the rail 7 functions as the guide surface portion 7a and the urging means 9 urges the rolling element 8 in the downward direction, the lower surface portion of the rail 7 functions as the guide surface portion and Compared with an aspect in which the urging means urges the rolling element upward, the rolling element 8 can be made to elastically contact the guide surface portion 7a by utilizing its own weight, Is preferred.

When abutting on the portion T, the arm portion 91 or the spring 92 does not abut on the abutting portion T, and a good abutting state can be ensured.

  The present invention is not limited to the embodiment described in detail above.

  For example, in the above-described embodiment, the case where the rolling element is applied as the operating element has been described. However, the operating element only needs to move along the guide surface portion of the rail, and a slider or the like may be applied as the operating element. Good.

  Moreover, you may provide the inclination angle adjustment means which can adjust the inclination angle of the inclination part which functions as a drawing-in action induction part in several steps. On the other hand, the retracting action inducing portion formed on the guide surface portion is not limited to the inclined portion shown in the above embodiment, and may be, for example, a partial arc shape or a partial ellipse shape. Moreover, you may change the formation area of the drawing operation | movement induction part which occupies for a guide surface part according to a use aspect or a user's needs. As an example, an aspect in which the retracting action inducing part is formed in a substantially half region of the guide surface part or an aspect in which it is formed in the entire region of the guide surface part can be given. Of course, it is needless to say that the pulling action inducing portions may be formed at other ratios. Thus, depending on the setting of the retracting action inducing portion, the distance at which the drawer is automatically retracted to the closed position can be appropriately adjusted.

  Further, the urging means of the retracting mechanism may be composed of only a spring that urges the actuator directly in the direction in which the actuator is brought into elastic contact with the guide surface portion. In the case where the arm portion is used, the shape of the arm portion may be appropriately changed. Further, the urging means comprises a cylinder and an advancing / retreating portion (piston rod) capable of advancing / retreating with respect to the cylinder, and the actuator is moved to the guide surface portion by appropriately advancing / retreating the advancing / retreating portion. You may make it urge in the direction made to elastically contact.

  On the other hand, the retracting mechanism is not provided with an urging means, and the retractor may be retracted to the closed position by moving the actuator along the retracting action inducing portion by its own weight. As a result, it is possible to effectively reduce the number of parts and simplify the structure.

  Furthermore, you may attach an actuator to a storage furniture main body or the side part of a drawer | drawer so that a vertical motion is possible directly without a base.

  Moreover, you may apply a normal slide rail mechanism as a support mechanism.

  As the spring mounting portion provided in the arm portion, a hooking claw or the like that can be hooked with one end of the spring may be adopted in addition to the mounting hole shown in the above embodiment.

  Alternatively, the lower surface portion of the rail may function as a guide surface portion, and the urging means may urge the rolling element in the upward direction so as to elastically contact the guide surface portion. In this case, when the inclined portion is applied as the pulling-in motion inducing portion, the inclined portion is inclined upward with respect to the horizontal direction.

  Moreover, the aspect which provided the rail in the side part (outward surface) of the drawer | drawer, and provided the operation element in the side part (inward surface) of the storage furniture main body may be sufficient.

  Further, as a guide portion, instead of a guide surface portion that can be in surface contact (can be surface contact) with the actuator as shown in the above-described embodiment, it can be in linear contact with an actuator such as a protrusion. You may apply what can be in line contact.

  On the other hand, a retracting mechanism X6 as shown in FIG. 6 may be applied. In addition, in the same figure, the member and means corresponding to the said embodiment attach | subject the code | symbol similar to the said embodiment, and shall abbreviate | omit the detailed description.

  The retracting mechanism X6 shown in the present modification has a structure substantially similar to that of the retracting mechanism 6 shown in the above embodiment, but has a guide surface portion X7a of the rail X7 and a plurality of first tooth portions X7b at a predetermined pitch. The difference is that a pinion X8 having a rack shape and a second tooth portion X8a that can mesh with the first tooth portion X7b is applied as an actuator.

  In this modification, the rail X7 is provided on the inward surface of the side surface portion 21 of the storage furniture body 2, and the pinion X8 formed as a unit, the biasing means 9 and the base B are provided on the outward surface of the drawer 4, and between the pinion X8. The pair of pinions X8 are coupled so as to be capable of synchronous rotation with a rod Xro interposed therebetween. The rod Xro is provided in the back (backward) from the back surface portion 42 of the drawer 4 so as not to interfere with the drawer 4.

  As the drawer 4 moves between the closed position (4x) and the open position (4y), the pinion X8 is urged by the urging means 9 in the direction of elastic contact with the guide surface portion X7a, and the second tooth portion It moves along the guide surface portion X7a while sequentially changing the relative meshing position of X8a and the first tooth portion X7b of the guide surface portion X7a. At this time, since the pair of pinions X8 rotate synchronously via the rod Xro, there is no moment in the horizontal turning direction acting on the entire drawer 4, and the drawer 4 can be moved in a reasonably stable state. .

  Even if it is such, the effect substantially the same as embodiment mentioned above can be acquired, and also the rolling element 8 is synchronized using the rail X7 which comprises the drawing mechanism X6, and the pinion X8 which is a rolling element. Therefore, the number of parts can be reduced and the structure can be simplified as compared with a mode in which a dedicated synchronization means is provided separately. In addition, the pinion X8, which is the actuator, moves along the guide surface portion X7a while engaging the second tooth portion X8a with the first tooth portion X7b, thereby ensuring accurate movement along the guide surface portion X7a of the pinion X8. Therefore, it is possible to effectively eliminate the risk that the rolling element X8 is detached from the guide surface portion X7a. In order to prevent the rod Xro from slipping with respect to the pinion X8, a square hole may be formed in the pinion X8, and a prismatic rod (not shown) may be inserted and attached to the square hole.

  Moreover, in the said embodiment, although the aspect provided with the single drawer was illustrated as storage furniture, of course, it may be provided with the some drawer. In addition, the storage furniture according to the present invention only needs to have a main body and a drawer that can move relative to the main body between a closed position and an open position, and one or more drawers may be provided on the sleeve portion.
