Description

Cabinet with drawers

The invention relates to a storage cabinet with drawers.

Known storage cabinets with drawers installed in kitchens etc. have proposed a pull-back device for pulling the drawers back to the closed position and maintaining them, and they are also widely popularized in ordinary households (see Patent Documents 1 and 2).

Patent Document 1 is Japanese PCT Publication No. 2015-526209; Patent Document 2 is Japanese PCT Publication No. 2017-530821.

The drawer pull-back device proposed by the above-mentioned patent documents 1 and 2 has the advantages that the drawer front panels are arranged side by side on the same vertical plane, which has a beautiful aesthetic feeling, and can be easily (automatically) pulled back to the final closed position. Yet, by the state of final closed position, when pulling out the front plate of drawer with human hand, when pulling out, for women or elderly people, also can take place the situation that is difficult to pull out because of insufficient force.

In order to solve the above problems, the purpose of the present invention is to provide a storage cabinet with drawers. Even women or those who are weak can easily and easily pull out the drawers from the final closed position.

In the present invention, the front panel of the drawer is wound around the left and right horizontal axis at the middle position in the up and down direction. The center is pivotally connected to the front end of the drawer body between the upright shape and the forward leaning shape; and it is provided with a lever mechanism. When the drawer is closed and an external force is applied to the upper edge of the front plate by hand, the front plate swings around the axis. The upper edge is the application point of the lever, and the axis is the load point of the lever, so as to generate the pull-out force for the initial movement of the drawer body to the front.

Furthermore, the fixing part next to the front opening is the front end surface of the side plate of the storage cabinet body.

Also, in the present invention, the front board of the drawer is pivotally connected to the front end of the drawer body freely swinging between the upright shape and the forward leaning shape around the left and right horizontal axes; and behind the lower end edge of the front board, an abutment member protruding from the rear is attached to form a fulcrum; and the upper and lower distance from the upper end edge of the front board to the abutment member is H₁₀, and at a distance of 0.2‧H upward from the abutting member₁₀More than 0.5‧H₁₀The axis is arranged in the following range; and a receiving tool for the abutting member for forming a fulcrum is fixed on the storage cabinet body; and a lever mechanism is provided. When the drawer is closed and an external force is applied to the upper edge of the front panel by hand, the front panel swings around the axis. The edge is the force point of the lever, and the axis is the load point of the lever, so as to generate the pulling force of the initial action that makes the drawer body move forward.

Furthermore, the receiving tool is provided with an inclined surface facing forward and downward for stopping. Furthermore, a tension spring and a shock absorber are arranged in the space on the back side of the front plate; the tension spring is applied to the front plate swinging forward to return to an upright shape; the shock absorber controls and slows down the recovery speed of the front plate. Furthermore, in the space on the back side of the front panel, an article storage bag with an upper opening is arranged; the bag is supported by the drawer body, and the load of the bag and the stored articles is configured so as not to generate a load on the front panel.

According to the present invention, as long as the upper edge of the front plate is pulled forward by hand, the front plate The system swings around the axis, and a part behind the lower end edge of the front panel pushes up the fixed part in such a way as to abut against the fixed part next to the front opening of the storage cabinet body, and the drawer can start to move forward gently by the reaction force.

According to the present invention, as long as the upper edge of the front plate is pulled forward by hand, the front plate system swings around the axis, and the rotating wheel system attached to the lower edge of the front plate pushes up (fixed) the receiving device of the storage cabinet body, and the drawer system can start to move forward slightly by the reaction force. And, viewed from the side, the front plate system forms a linear lever, which swings around the axis, and the reaction force is increased several times, so that the front plate can start to move before the sliding door.

Near the rear end of the sliding door, since the pull-back device (mentioned above) is generally provided, the initial action to the front of the sliding door is relatively heavy. The present invention can carry out such a heavy initial action lightly, so it can help women or those who are physically weak.

Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings. Figures 1 to 4 are examples illustrating the storage cabinet C with drawers, and the drawer 1 is pulled out from the storage cabinet body 3 in various states, which are sequentially revealed in three-dimensional views.

The drawer 1 includes a front panel 10 , a back panel (rear panel) 11 , a bottom panel 12 and a side frame (side panel) 13 , and has an article storage space 14 with an upper opening. Symbol 4 is the left and right slide rails, the outer cylinder 4A of the slide rail 4 is fixed on the storage cabinet body 3 to form a part thereof, and the insert body 4B is fixed on the left and right side panels 13 of the drawer 1 . Furthermore, the storage cabinet body 3 includes an opening 3A on the front side. In the illustration, the front panel 3B is included, and its lower edge forms the upper edge of the opening 3A.

Moreover, the front panel 10 is pivotally connected to the front end 2F of the drawer body 2 around the horizontal axis L ₁ . That is, it can freely swing between the upright form Sv of the front panel 10 shown in Fig. 1 (Fig. 4) and the forward-inclined form Sc shown in Fig. 2 (Fig. 3), and is pivotally connected to the front end 2F of the drawer body 2 with the latch 20, and freely swings around the horizontal axis _L1 .

As shown in Figures 5 to 10, the groove member 16 fixed on the back of the front plate 10 is pivotally connected to the front end of the side plate 13 fixed on the drawer body 2 through the latch 20 to raise the plate 15 . In this way, the front panel 10 of the drawer 1 can be pivotally connected to the front end 2F of the drawer body 2 around the horizontal axis L ₁ between the upright shape Sv and the forward leaning shape Sc.

And, the front plate 10 is attached to the rear face 17 of its lower end edge 10Z (in order to form (1) of a fulcrum to be described later forms the contact member 18 for a fulcrum. As the abutting member 18 for forming the fulcrum, it is formed by pivotally connecting the small rotating wheel 5 shown in Fig. 12 (A) to the fixed seat 6 freely rotatably around the horizontal axis;

Moreover, if the vertical distance from the upper edge 10T of the front plate 10 to the abutting member 18 is _H10 , the axis _L1 (the pin 20) is arranged within a range from the abutting member ₁₈ of 0.2‧H10 to _0.5‧H10 . That is, in Fig. 5 (A) and (B), if the vertical distance dimension from the abutment member 18 to the axis L ₁ (plug pin 20) is H ₂ , then it is better to form: 0.2‧H ₁₀ ≦H ₂ ≦0.5‧H ₁₀ (mathematical formula 1)

Furthermore, it is more preferable to form: 0.25‧H ₁₀ ≦H ₂ ≦0.4‧H ₁₀ (mathematical formula 2)

(The reason for setting such mathematical formula 1 and mathematical formula 2 will be described later).

Next, the receiving tool 8 for the abutting member 18 for forming a fulcrum is fixedly installed on the storage cabinet body 3 . In the illustration, at the front end of the cylindrical body 4A outside the slide rail 4, a receiving tool 8 including an inclined surface 9 facing downward and forward is fixedly installed. The outer cylindrical body 4A of the slide rail 4 is fastened to the storage cabinet body 3 , which is a component of the storage cabinet body 3 . And from the closed state of the drawer shown in Fig. 5 (A), when the front panel 10 upper edge 10T is applied with a front pulling external force F ₁₀ by hand, the front panel 10 swings around the axis _L1 , then as shown in Fig. 6, the abutment member 18 for forming a fulcrum shakes as shown by the arrow R ₈ , and pushes up the fixed receiving tool 8 in a manner of contacting the fixed receiving tool 8.

That is, the push-up point of the abutment constitutes the lever fulcrum P ₁ . Furthermore, the top edge 10T of the front plate 10 is the force application point P ₂ of the lever, which is the forward pulling force F ₁₀ applied by the hand. Moreover, the axis L ₁ (the pin 20 ) forms the load point P ₃ of the lever, which is for generating the pull-out force F ₂ of the initial action to pull the drawer 1 forward.

In this way, as shown in Fig. 5 (A) and (B), the present invention has a lever mechanism Z. The lever mechanism Z is equipped with a fulcrum P ₁ , a force point P ₂ , and a load point P ₃ of the lever. The lever mechanism Z generates an initial action pulling force F ₂ as shown in Fig. 5 (B), and the initial action pulling force F ₂ is used to make the drawer 1 move forward. . In particular, the lever mechanism Z of the present invention is referred to as "type 2" lever mechanism Z, which can generate the pull-out force F ₂ of the initial action with a larger magnification (ie F ₂ /F ₁₀ ).

Next, another embodiment of the present invention will be described as follows. It omits the structure of the abutting member 18 (rotating wheel 5 ) and the receiving tool 8 for forming a fulcrum in the aforementioned embodiment. Other than that, it is the same as the aforementioned embodiment, so it may be described while referring to the diagrams in Fig. 1 to Fig. 11 . That is, in another embodiment, a part of the rear surface 17 of the lower end edge of the front panel 10 pushes up the fixing part in such a way as to abut against the fixing part next to the front opening 3A of the storage cabinet body 3 . Since the abutting member 18 and the receiving tool 8 are omitted, it is better to attach the elastic sheet to a part of the back 17 of the lower end edge, or to the fixed part of the storage cabinet body 3 to prevent damage and noise.

The "fixed part" next to the front opening 3A of the storage cabinet body 3 is preferably the front end faces of the left and right side panels of the storage cabinet body 3 . Alternatively, if there are left and right pillars in the front opening 3A of the storage cabinet body 3, these pillars are used as "fixed parts". Furthermore, the (fixed) outer cylindrical body 4A of the slide rail 4 can also be extended forward, and the front end can be used as a "fixed part". At this time, the "fixed part" at the front end is preferably provided with an elastic plug for buffering to prevent damage and avoid noise.

Then, as shown in Fig. 6, the present invention is provided with the tension spring 21 of homing, and it is to apply the elastic force in order to restore (return) to the upright form shown in Fig. 5 (A) to plate 10 before swinging forward. That is, the upper end 21A of the tension spring 21 is fixedly connected to the mounting part 22 protruding from the back side 10B of the front panel 10 , and the lower end 21B is fixedly connected to the lower part of the front end 2F of the drawer body 2 . The central axis of the tension spring 21 in the up and down direction is located at a position more rearward than the axis _L1 of the pivoted front plate 10 (i.e. the position in the right direction in Figs.

Moreover, a shock absorber 23 is attached, which slows down the speed at which the front plate 10 returns to the upright configuration in FIG. 5 from the swing tilt state in FIG. 6 by the elastic pressure of the tension spring 21, so as to ensure the safety of the operator. The damper 23 is formed, for example, of a hydraulic cylinder structure in which a piston including an orifice is mounted. As can be seen from FIG. 5 (A) and FIG. 6, the tension spring 21 and the shock absorber 23 are arranged in the space 24 on the back side 10B of the front panel 10 .

Next, the symbol 30 is a bag-like piece for storing articles with an upper opening. The pocket 30 is arranged in the space 24 on the back side 10B side of the front panel 10 . Moreover, the bag 30 is supported by the drawer body 2 . That is, the bag-like part 30 is supported on the upper stand-up panel 15 which is fixed at the front end of the side panel 13 of the drawer body 2 . However, it is not supported by the front plate 10 . In further detail, in the 8th figure, the plate 15 that is fixed to stand upward from the front end of the side plate 13 of the drawer body 2 is formed by the gap of the upper side 15A to form an inclined slit groove 15S viewed from the side. The slit groove 15S is formed in an inclined shape downward and rearward.

On the other hand, the short axis 31 of circular cross-section protrudes from the left and right sides of the bag-like member 30 , and the short axis 31 is inserted into the slit groove 15S of the standing plate 15 above. Therefore, the bag-like part 30 is fixed on the drawer body 2 provided with the upper standing plate 15 . Moreover, the lower end of the bag-like member 30 is supported on the lower part of the front end of the drawer body 2 in a contact manner (omitted in the figure). That is, the full load of the bag-shaped part 30 and the articles contained therein will not produce a load on the front panel 10; as shown in Fig. Moreover, by setting the inclination angle of the slit groove 15S, as shown in FIG. 6, the inclination (dumping) angle of the bag-like member 30 can be freely set according to a desired percentage relative to the inclination angle of the front plate 10.

However, in Figure 5 (A), Figure 6 and Figure 8, etc., the description The main functional components such as tension spring 21, shock absorber 23 and mounting piece 22 for homing, as shown in Fig. 10 and Fig. 11, can be formed (not exposed) to be accommodated in the surrounding shell 35 which is roughly in the shape of a rectangular tube. Moreover, the front wall 36 surrounding the casing 35 in a substantially rectangular tubular shape is formed to abut against the front plate 10 (omitted in this figure) in subsequent additional operations (that is, after the assembly unit is formed as shown in FIG. 10 ) and can be attached to the formation of the mounting hole 37. Furthermore, headed bolts are fixed in advance on the back side 10B of the front plate 10, and as long as they are pressed into the installation holes 37 to fix them, the front plate 10 can be quickly and easily attached.

Furthermore, in Figures 1 to 4 and other figures, in order to easily apply the forward pulling force F ₁₀ on the upper edge 10T of the front plate 10 by hand, it is preferable to form a notch or a small window, or attach a handle or a U-shaped pull rod. At this time, the "upper edge" as the reference position for measuring the vertical distance dimension _H10 is equivalent to the lower edge of the notch recess, the upper and lower center position of the small window, and the attached height position of the handle or pull rod.

本發明如上所詳述，由於其係使抽屜1之前板10繞上下方向中間位置之左右水平狀軸心L ₁ ，於直立狀形態Sv與前傾狀形態Sc之間自由擺動地樞接在抽屜本體2之前端2F；及具備槓桿機構Z，其係在由抽屜閉合狀態，藉由人手對該前板10之上端緣10T施加前拉外力F ₁₀時，該前板10繞該軸心L ₁而擺動，且該前板10之下端緣後面17之一部分係以抵接至收納櫃本體3之前方開口部3A旁邊之固定部的方式推升該固定部，該抵接之推升點係形成槓桿支點P ₁ ，同時以前板10之該上端緣10T為槓桿之施力點P ₂ ，並以該軸心L ₁為槓桿之負載點P ₃ ，以產生使抽屜本體2往前方起始動作之起始動作拉出力F ₂ ，因此，槓桿機構Z係作為第2種槓桿而作用，使得較大之起始動作拉出力F ₂對抽屜本體2產生作用。 Therefore, even if the drawer body 2 is provided with a pull-back device at the final closed position, for women, children or those who are infirm, the drawer body 2 can be pulled out (together with the front panel 10) easily and smoothly.

Moreover, when the external force F ₁₀ is applied to the upper end edge 10T of the front panel 10 by hand, the front panel 10 swings on one side, and the rear surface 17 of the lower edge of the front panel 10 and the fixed part at the front of the storage cabinet body 3 are pushed up in abutting manner, so that the front initial action of the drawer body 2 can be easily and smoothly started. Thereafter, the upper edge 10T can be continuously and smoothly moved forward by continuously holding the upper end edge 10T with the hand.

Furthermore, since the fixed portion next to the front opening 3A is the front end surface of the side plate of the storage cabinet body 3, no special parts need to be attached, at most, the degree of sticking the damage-preventing elastic sheet can be solved.

再者，由於其係使抽屜1之前板10繞左右水平狀之軸心L ₁ ，於直立狀形態Sv與前傾狀形態Sc之間自由擺動地樞接在抽屜本體2之前端2F；及在前板10之下端緣後面17，附設後方突出狀之形成支點用抵接構件18；及以由前板10之上端緣10T至該抵接構件18止之上下間距尺寸為H ₁₀ ，並在由該抵接構件18往上方距離0.2‧H ₁₀以上且0.5‧H ₁₀以下之範圍配設該軸心L ₁ ；及在收納櫃本體3固設供該形成支點用抵接構件18自由抵接之承接具8；及具備槓桿機構Z，其係在由抽屜閉合狀態，藉由人手對該前板10之上端緣10T施加前拉外力F ₁₀時，該前板10繞該軸心L ₁而擺動，且該形成支點用抵接構件18係以抵接固定承接具8的方式推升固定承接具8，該抵接之推升點係形成槓桿支點P ₁ ，同時以前板10之該上端緣10T為槓桿之施力點P ₂ ，並以該軸心L ₁為槓桿之負載點P ₃ ，以產生使抽屜本體2往前方起始動作之起始動作拉出力F ₂ ，因此，槓桿機構Z係作為第2種槓桿而作用，使得較大之起始動作拉出力F ₂對抽屜本體2產生作用。 Therefore, even if the drawer body 2 is provided with a pull-back device at the final closed position, for women, children or those who are infirm, the drawer body 2 can be pulled out (together with the front panel 10) easily and smoothly.

Moreover, when the front panel 10 is subjected to a forward pulling force F10 applied to the upper edge _10T of the front panel 10 by hand, the front panel 10 swings on one side, and the abutting member 18 abuts (pulls up) the receiving tool 8, so that the front initial movement of the drawer body 2 can be easily started, and the upper edge 10T can be continuously held by the hand, so that the forward movement can be carried out continuously and smoothly with a natural feeling.

Moreover, the pull-out force F ₂ in the initial action is 2 to 5 times greater than the pull-out force F ₁₀ of the upper edge 10T of the front plate 10 by hand, so even women or those who are physically weak can pull out the drawer 1 very easily. Furthermore, if the shaft center _L1 is arranged at a position less than 0.2‧H10, the front plate 10 must be tilted forward too much, so the distance to move the upper edge 10T by hand will become too large, and _the operation will suddenly become troublesome. Conversely, if the axis L ₁ is arranged at a position exceeding 0.5‧H ₁₀ , the pulling force (forward pulling external force F ₁₀ ) of the upper edge 10T forward by the human hand will feel too large, and it is impossible to assist a weaker person.

Furthermore, since the receiving tool 8 is provided with an inclined surface 9 facing forward and downward, the abutment member 18 that swings around the axis _L1 is sure to abut (push up) the inclined surface 9, and the abutment member 18 forms contact along the inclined surface 9 for a long time, so that the drawer body 2 can be moved forward (pull out).

Moreover, since the space 24 on the back side 10B side of the front plate 10 is equipped with a tension spring 21 and a shock absorber 23 for returning, the tension spring 21 for the return is applied to the front plate 10 swinging forward to return to the elastic force of the upright shape Sv; The system returns to the upright form Sv smoothly and quietly. In this way, it can also give users an elegant and high-end feeling in places such as the kitchen.

Furthermore, because in the space 24 on the back side 10B side of the front panel 10, an article _storage bag 30 with an opening above is provided; Moreover, in the forward-inclined form Sc, the upper opening of the bag 30 exists near the back surface 10B of the front panel 10, so that identification of stored items and access to the items can be easily performed.
