Description

  The present invention relates to a sliding door used as a fitting for a building such as a house. More specifically, the present invention relates to a sliding door provided with a pulling groove for hooking fingers when opening and closing.

Conventionally, in addition to pure Japanese-style sliding doors such as shochu and shoji, new-style Japanese-style sliding doors and Western-style sliding doors that have a sense of incongruity with Western-style doors have been used as fittings.
These new types of sliding doors are heavy because they have many elaborate designs, and their resistance is too high when they are opened and closed by sliding such as a saddle or shoji. Therefore, it is common to use a door cart. And, for example, a small pull handle with two or three fingertips is attached and opened and closed.

However, even if a door cart is used, if the sliding door is too heavy, it may be difficult to open and close with a small handle. In addition, there is a problem that the position of the handle is too high when a small child opens or closes, and the position of the handle is too low when the person is tall.
Furthermore, when the sliding door is opened, the sliding door and the wall or a plurality of doors overlap with each other, so that there is a problem that a hand or a finger is caught between the sliding door and the wall or between the sliding door and the sliding door.

On the other hand, Patent Document 1 describes an invention related to a sliding door in which a groove for pulling is provided from the upper end to the lower end of both sides of the sliding door so that the finger can be easily put on regardless of the height. Further, Patent Document 2 describes an invention related to a sliding door in which a concave / convex surface is formed in a groove for pulling provided in the vertical direction of the sliding door to make it easy to put a finger.
Patent Document 3 describes an invention related to a pulling handle that prevents a finger from being pinched by retracting into a sliding door body when the sliding door is opened. Patent Document 4 describes an invention related to a pulling handle that prevents the fingers from being pinched by forming the central portion of the pulling handle in a raised manner.

However, the sliding door provided with the groove for the pulling in the vertical direction, such as the sliding door described in Patent Document 1, has the following problems. FIG. 13 is a perspective view showing a sliding door according to such a conventional example.
The sliding door 500 according to the conventional example is formed by attaching vertical eaves 5 and 5 to both sides of the base material 4. And the pulling groove | channel 50 is continuously provided in the front and back of the vertical hooks 5 and 5 from an upper end part to a lower end part.

In the sliding door 500, when the pulling groove 50 is shallow, it is difficult for a finger to be caught and a force cannot be applied as expected. In addition, in the case of a woman with long nails, it is particularly difficult to get fingers.
On the contrary, when the pulling groove 50 is deep, it is easy to put a finger, but there is a possibility of penetrating to the opposite side with a thin sliding door, and the lower end of the sliding door or the upper end as shown below. It becomes difficult to install the runner.

FIG. 14 is a bottom view of the sliding door 500, and FIG. 15 is a plan view of the sliding door 500.
As shown in FIG. 14, close doors 7 and 7 are pivotally attached to both side surfaces of the lower end portion 2 of the sliding door 500 so that the sliding door can be moved smoothly. In attaching the door pulley 7, a box-shaped recess is provided on the lower surface of the sliding door 500 to embed the door wheel housing box 71, and the door wheel 7 is arranged inside the door wheel housing box 71. Moreover, the adjustment mechanism 72 for adjusting the position of the door pulley 7 after construction is provided, and the adjustment screw is operated from the end of the sliding door. Further, as shown in FIG. 15, runners 6 and 6 are attached to both sides of the upper end portion 1 of the sliding door 500 and move inside the groove provided in the duck at the time of opening and closing.

Here, when the pulling groove 50 is deep, as shown in FIG. 14, the pulling groove 50 enters the place where the carriage housing box 71 and the adjustment mechanism 72 are arranged at the lower end 2 of the sliding door 500. Therefore, the installation of the door pulley 7 will be hindered. Similarly, as shown in FIG. 15, the attachment position of the runner 6 at the upper end is limited to the inside, or the adjustment mechanism 61 cannot be attached to the runner 6.
Furthermore, when the groove is formed up to the upper end 1 and the lower end 2 of the sliding door 500, the side of the groove of the duck or the sill in this portion is visible and unsightly, and dust tends to accumulate.

  On the other hand, like the sliding door described in Patent Document 2, it is conceivable not to provide a pulling groove on the upper end or lower end of the sliding door, but the line breaks in the vicinity of the upper and lower ends. It becomes halfway up. Further, if there is no groove at the upper end portion or the lower end portion, the pulling groove becomes a complete recess, so that lapping becomes extremely difficult when lapping is performed later.

  On the other hand, the finger clamp prevention puller described in Patent Document 3 is a mechanical pull-in puller and is difficult to apply to a sliding door formed continuously from the upper end to the lower end of the sliding door. . In addition, when the handle for preventing finger pinching described in Patent Document 4 is applied to a sliding door formed continuously from the upper end portion to the lower end portion of the sliding door, similarly to the above, at the upper end portion and the lower end portion of the door plate, This will interfere with the installation of the door pulley or runner.

  Accordingly, the present invention is for solving the above-described conventional problems, and in a sliding door provided with a pulling groove continuously from the upper end portion to the lower end portion, at the same time as ensuring a sufficient depth of the pulling groove for hooking fingers. Further, the present invention provides a sliding door that enables installation of a door wheel or a runner at the upper end or lower end of the sliding door, and further prevents finger pinching.

In order to solve the above-mentioned conventional problems, the sliding door of the invention according to claim 1 is a plate material in which at least one of the front surface and the back surface of the plate material is provided with a handle groove (10) for putting fingers on the side surface when opening and closing. The sliding door (100) is provided continuously from the upper end (1) to the lower end (2) of the upper end (1) and the lower end (2). ) From the lower plate (2) to the central portion (3) in the vertical direction, and the thickness of the remaining plate material in which the handle groove (10) is formed in the lower end (2) (7) is set wider than the installation width of the door cart storage box (71) in which the door is rotatably arranged, and the lower end portion (2) of the door cart storage box (71) in the left-right direction for opening and closing the sliding door (100). ) Of the remaining plate material in which the pulling groove (10) is formed. While entering the band, characterized regard thickness direction of the plate, as the pull grooves to the installation position of the door roller accommodating box (71) (10) does not enter, that is embedded in the lower end portion of the plate (2) And

Further, in the invention according to claim 2, a pulling groove (10) for placing a finger at the time of opening and closing at least one of the front surface and the back surface of the plate material is provided at the lower end portion (1) from the upper end portion (1) of the plate material. 2) The sliding door (100) provided continuously up to 2), wherein the depth of the pulling groove (10) is changed from the upper end (1) and the lower end (2) to the central portion (3) in the vertical direction. And the thickness of the remaining plate material on which the handle groove (10) is formed at the lower end (2) is made wider than the installation width of the door roller (7), and As for the left and right direction of opening and closing the sliding door (100), the door wheel (7) enters the region of the remaining plate material forming the pulling groove (10) in the lower end portion (2), but the thickness direction of the plate material With regard to the door groove (7), the handle groove ( 0) so as not to penetrate, characterized in that embedded in the lower portion (2) of the plate.

Further, the invention according to claim 3 is the invention according to claim 1 or 2, wherein the central portion (21) in the horizontal direction of the pull groove (20) is protruded, and the pull groove (20) is formed. It is characterized by being formed in a substantially M-shaped cross section .

The invention according to claim 4 is characterized in that a pulling groove (30) for placing a finger on the side surface of at least one of the front surface and the back surface of the plate material at the time of opening / closing is provided from the upper end portion (1) to the lower end portion ( 2) The sliding door (300) provided continuously up to 2), wherein the depth of the pulling groove (30) is changed from the upper end (1) to the lower end (2) of the plate material, and the upper end (1) ) And the depth of the handle groove (30) at the lower end portion (2) so as to be shallower than the depth of the handle groove (30) at portions other than the upper end portion (1) and the lower end portion (2). In the pulling groove (30), the left inclined portion (31) whose left side is deep and the right side is shallow and the right inclined portion (32) where the right side is deep and the left side is shallow are alternately formed in the vertical direction. And

  The symbols in parentheses indicate the best mode for carrying out the invention and the corresponding elements or the corresponding matters described in the drawings.

According to the present invention , since the pulling groove is provided in the portion closer to the side surface in at least one of the front surface and the back surface of the plate material, the sliding door can be opened and closed by placing a finger on the pulling groove.
In addition, since the pulling groove is continuously provided from the upper end portion to the lower end portion of the plate material, it is possible to accurately place the finger on the sliding door regardless of the height. In addition, since the lines do not break near the upper and lower ends of the sliding door, it is excellent in design. Further, lapping can be easily performed later.
In addition, the depth of the handle groove at the upper end and the lower end of the sliding door is formed so as to be shallower than the depth of the handle groove at the portion other than the upper end and the lower end, so that the groove is shallow at the upper end and the lower end. As a result, it is possible to install a door pulley or runner, and it is difficult to see the groove side of the duck and the sill, it looks good, and dust does not collect easily. Further, in the other portions, the groove can be deepened and the function as a handle can be sufficiently exhibited.

In addition, according to the present invention, the depth of the pulling groove is gradually increased from the upper end portion and the lower end portion toward the center portion in the vertical direction, so that the grooves at the upper end portion and the lower end portion are made shallower, The depth of the groove corresponding to the function as a puller can be set by making the depth of the groove at the center, which is a part where fingers are frequently applied, deepest.

In addition, according to the present invention, since the central portion in the horizontal direction of the pulling groove is protruded and the pulling groove is formed in a substantially M-shaped cross section , the fingers follow the inclination of the pulling groove at the final stage of opening the sliding door. Are automatically discharged, and hands and fingers are not pinched between the sliding door and the wall or between the sliding door and the sliding door.

Further , according to the present invention, in the pulling groove, the left inclined portion where the left side is deep and the right side is shallow and the right inclined portion where the right side is deep and the left side is shallow are alternately formed in the vertical direction. When the sliding door is moved to the right side, it can be moved by placing the finger on the right inclined portion.
Further, at the final stage of opening the sliding door, the fingers are automatically discharged along the inclination of the pulling groove so that the hands and fingers are not sandwiched between the sliding door and the wall or between the sliding door and the sliding door.

Next, the sliding door according to Embodiment 1 of the present invention will be described with reference to FIGS.
FIG. 1 is a partial perspective view showing a sliding door 100 according to the first embodiment. The sliding door 100 is formed by attaching vertical hooks 5 and 5 to both sides of the base material 4. FIG. 1 shows only the vertical gutter 5 on one side, but the vertical gutter 5 is similarly attached to the opposite side.
On the front and back surfaces of the vertical fence 5, pulling grooves 10 and 10 are continuously provided from the upper end 1 to the lower end 2 of the sliding door 100. When the sliding door 100 is opened and closed, the fingers are placed on the pulling grooves 10 and 10 so that the fingers can be hooked regardless of the height.
Moreover, the runner 6 which moves the inside of the groove | channel provided in the Kamoi at the time of opening and closing is attached to the upper surface of the sliding door 100. As shown in FIG. Further, the door 7 is rotatably attached to the lower surface of the sliding door 100, and moves on a rail provided on the sill when opening and closing.

Next, the shape of the pulling groove 10 will be described with reference to FIGS. 2 is an XX sectional view of FIG. 1, FIG. 3 is (a) a plan view in the A direction, (b) BB sectional view, (c) CC sectional view of FIG. (D) DD sectional drawing, (e) E direction bottom view. In addition, about FIG. 3, only the part of the vertical gutter 5 is shown.
As shown in FIGS. 2 and 3, the pulling groove 10 is formed so as to gradually become deeper from the upper end portion 1 and the lower end portion 2 toward the central portion 3 in the vertical direction. That is, the depth of the pulling groove 10 gradually increases from the upper end portion 1 toward the central portion 3 and gradually decreases from the central portion 3 toward the lower end portion 2. And the depth in the upper end part 1 and the lower end part 2 is the shallowest, and the depth in the center part 3 is the deepest. Further, the cross-sectional shape of the pull groove 10 is a rectangular recess.
In addition, the depth of the handle groove 10 in the upper end part 1 and the depth of the handle groove 10 in the lower end part 2 may be the same as in this embodiment, or may be different. Further, the change in depth from the upper end 1 and the lower end 2 toward the center 3 may be linear as in the present embodiment, or may be curvilinear.

The depth of the pulling groove 10 is, for example, about 1 to 2 mm at the upper end 1 and the lower end 2, and may be determined as follows.
FIG. 4 is a bottom view of the sliding door 100, and FIG. 5 is a plan view of the sliding door 100.
As shown in FIG. 4, door pulleys 7 and 7 are attached to both sides of the lower end portion 2 of the sliding door 100. In attaching the door wheel 7, a box-shaped recess is provided on the lower surface of the sliding door 100 to embed the door wheel housing box 71, and the door wheel 7 is rotatably disposed inside the door wheel housing box 71. Moreover, the adjustment mechanism 72 for adjusting the position of the door wheel 7 after construction is provided, and the adjustment screw is operated from the wooden end of the sliding door 100.
Here, the depth of the pulling groove 10 is such a depth that it does not enter the place where the door cart storage box 71 and the adjustment mechanism 72 are arranged at the lower end 2 of the sliding door 100. In other words, the thickness of the remaining sliding door 100 in which the pulling groove 10 is formed is formed so as to be wider than the installation width of the door carriage storage box 71 and the adjustment mechanism 72. As a result, there is no problem in mounting the door cart 7.

As shown in FIG. 5, runners 6 and 6 are attached to both side surfaces of the upper end portion 1 of the sliding door 100. The runner 6 is also provided with an adjustment mechanism 61 for adjusting the position after construction, as with the door cart 7, and the adjustment screw is operated from the wooden end of the sliding door 100.
Here, the depth of the pulling groove 10 is such a depth that the runner 6 and the adjusting mechanism 61 at the upper end 1 of the sliding door 100 do not enter. That is, the thickness of the remaining sliding door 100 in which the pulling groove 10 is formed is formed to be wider than the installation width of the runner 6 and the adjusting mechanism 61. Thereby, the installation of the runner 6 is prevented from being hindered.

The pulling groove 10 at the upper end 1 and the lower end 2 may be of a minimum level that can be recognized as a groove or a line when viewed from the front, and a function as a pulling handle is not required. And by setting it as the minimum groove | channel, it is hard to see the groove side surface of a duck or a sill, and it is hard to collect dust.
However, when there is no groove at the upper end 1 and the lower end 2, the line is interrupted near the upper and lower ends, the design is halfway, and the pulling groove becomes a complete recess. When lapping is performed, lapping becomes extremely difficult. Therefore, a minimum number of grooves are required.

On the other hand, the depth of the pulling groove 10 in the central portion 3 is, for example, about 5 to 15 mm, but varies depending on the thickness of the sliding door 100.
Since the central portion 3 is a portion that is most likely to be used when the sliding door 100 is opened and closed, it is preferable to increase the depth of the pulling groove 10 so that fingers can be easily inserted. However, in consideration of forming the pulling grooves 10 from both the front and back surfaces, the thickness is less than half of the thickness of the sliding door 100.
Thus, since the depth of the pulling groove 10 is gradually increased from the upper end 1 and the lower end 2 toward the central portion 3, the deeper the groove is formed in the portion that is often used as a pulling handle. Yes.

As described above, according to the sliding door 100 according to the first embodiment, since the pulling grooves 10 are provided on the front and back surfaces of the vertical fence 5 of the sliding door 100, the finger 100 is put on the pulling grooves 10 to open and close the sliding door 100. Can do.
In addition, since the pulling groove 10 is continuously provided from the upper end 1 to the lower end 2 of the vertical hook 5, the finger can be accurately placed on the sliding door 100 regardless of the height. Moreover, since the line does not break near the upper and lower ends of the sliding door 100, the design is excellent. Further, lapping can be easily performed later.

  Moreover, since the depth of the handle groove 10 in the upper end part 1 and the lower end part 2 of the sliding door 100 was formed so as to be shallower than the depth of the handle groove 10 in parts other than the upper end part 1 and the lower end part 2, the upper end part 1 In addition, at the lower end 2, the groove is made shallow so that the door wheel 7 and the runner 6 can be installed, and the groove side surface of the duck and the sill is difficult to see and looks good, and dust is not easily collected. Further, in the other portions, the groove can be deepened and the function as a handle can be sufficiently exhibited.

  Further, since the depth of the pulling groove 10 is gradually increased from the upper end portion 1 and the lower end portion 2 toward the central portion 3 in the vertical direction, the grooves of the upper end portion 1 and the lower end portion 2 are made shallower, The depth of the groove corresponding to the function as the handle can be set by making the depth of the groove of the central portion 3 where the fingers are frequently applied deepest.

Next, with reference to FIG. 6 thru | or FIG. 9, the sliding door which concerns on Embodiment 2 of this invention is demonstrated.
FIG. 6 is a partial perspective view showing the sliding door 200 according to the second embodiment. The sliding door 200 has substantially the same configuration as the sliding door 100 according to the first embodiment, but the shape of the pulling groove formed in the vertical fence 5 is different. In addition, about the part same as the sliding door 100 which concerns on Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  On the front and back surfaces of the vertical fence 5 of the sliding door 200, the pulling grooves 20, 20 are continuously provided from the upper end 1 to the lower end 2 of the sliding door 200. When the sliding door 200 is opened and closed, the fingers are placed on the pulling grooves 20 and 20 so that the fingers can be hung regardless of the height.

Next, the shape of the pulling groove 20 will be described with reference to FIGS. 7 is a (y ₁ ) Y ₁ -Y ₁ cross-sectional view, (y ₂ ) Y ₂ -Y ₂ cross-sectional view, and (y ₃ ) Y ₃ -Y ₃ cross-sectional view of FIG. 8 is a plan view in the F direction, (g) GG sectional view, (h) HH sectional view, (i) II sectional view, and (j) J in FIG. It is a bottom view of a direction. In addition, about FIG. 8, only the part of the vertical gutter 5 is shown.
As shown in FIGS. 7 and 8, the pulling groove 20 is formed so as to gradually become deeper from the upper end portion 1 and the lower end portion 2 toward the central portion 3 in the vertical direction. That is, the depth of the pulling groove 20 gradually increases from the upper end portion 1 toward the central portion 3 and gradually decreases from the central portion 3 toward the lower end portion 2. And the depth in the upper end part 1 and the lower end part 2 is the shallowest, and the depth in the center part 3 is the deepest. In addition, it is a flat surface from the upper end part 1 and the lower end part 2 toward the center part 3 for a while.

The cross-sectional shape of the pulling groove 20 is substantially M-shaped. That is, the central portion 21 in the horizontal direction of the pulling groove 20 protrudes in the opening direction of the groove, and is a protrusion from the upper end 1 to the lower end 2. The protruding height of the central portion 21 is substantially the same as the height of the front and back surfaces of the sliding door 200, and is the same height from the upper end portion 1 to the lower end portion 2.
In addition, as shown in FIG. 8, the slope of the mountain in the groove having a substantially M-shaped cross section formed by the protrusion of the central portion 21 is gentler toward the upper end portion 1 and the lower end portion 2 and toward the central portion 3. It's sudden.

FIG. 9 is a cross-sectional view illustrating a state when the sliding door 200 according to the second embodiment is opened and closed. With reference to FIG. 9, the finger pinching prevention action when opening and closing the sliding door 200 will be described. In FIG. 9, only the portion of the vertical fence 5 is shown in the sliding door 200, and reference numeral 8 denotes a wall in which the sliding door 200 is stored.
When the sliding door 200 is moved to the wall 8 side, the finger is moved by being hung on the pulling groove 20 provided on the vertical shaft 5. At this time, the finger is moved while applying a force to the wall surface 22 in the direction to be moved in the pulling groove 20 by a finger. In the final stage of the movement, the pulling groove 20 is also accommodated in the wall 8. At this time, as shown in the drawing, the fingers hung on the pulling groove 20 follow the inclination formed in the pulling groove 20 along the wall. 8 is pushed to the opposite side to 8 and is discharged from the pulling groove 20. Thereby, it is possible to prevent fingers from being pinched.
Such a finger discharging effect is small in the vicinity of the upper end 1 and the lower end 2 where the slope of the pull groove 20 is gentle, and large in the vicinity of the central portion 3 where the slope of the mountain is steep. The portion that is more likely to be used (the portion that is more likely to pinch fingers) has a higher discharge effect.

  As described above, according to the sliding door 200 according to the second embodiment, since the central portion 21 in the horizontal direction of the pulling groove 20 is protruded and the pulling groove 20 is formed in a substantially M-shaped cross section, the sliding door 200 is opened. In the final stage, the fingers are automatically discharged along the inclination of the pull groove 20, and the hands and fingers are not sandwiched between the sliding door 200 and the wall 8. The same applies to the case where the sliding door overlaps with the sliding door instead of being stored in the wall.

Next, with reference to FIG. 10 thru | or FIG. 12, the sliding door which concerns on Embodiment 3 of this invention is demonstrated.
FIG. 10 is a partial perspective view showing the sliding door 300 according to the third embodiment. Although the sliding door 300 is the structure substantially the same as the sliding door 100 which concerns on Embodiment 1, the shape of the pulling groove formed in the vertical fence 5 differs. In addition, about the part same as the sliding door 100 which concerns on Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  On the front and back surfaces of the vertical fence 5 of the sliding door 300, the pulling grooves 30, 30 are continuously provided from the upper end 1 to the lower end 2 of the sliding door 300. When the sliding door 300 is opened and closed, the fingers are placed on the pulling grooves 30 and 30 so that the fingers can be hooked regardless of the height.

Next, the shape of the pulling groove 30 will be described with reference to FIGS. 11 is a (z ₁ ) Z ₁ -Z ₁ cross-sectional view, (z ₂ ) Z ₂ -Z ₂ cross-sectional view, and (z ₃ ) Z ₃ -Z ₃ cross-sectional view of FIG. 12 is a plan view in the (k) K direction, (l) LL sectional view, (m) MM sectional view, (n) NN sectional view, (o) O in FIG. It is -O sectional drawing, (p) The bottom view of a P direction.
In addition, about FIG. 12, only the part of the vertical gutter 5 is shown.
As shown in FIGS. 11 and 12, the pulling groove 30 has a shape in which a plurality of recesses are formed near the center of the flat groove. As a result of providing the plurality of recesses, the depth at the upper end 1 and the lower end 2 is the shallowest, and the depth at portions other than the upper end 1 and the upper end 2 is deeper than this.

The plurality of concave portions formed in the pulling groove 30 are classified into two types, a left inclined portion 31 and a right inclined portion 32. As shown in FIG. 12, with respect to the depth of the pulling groove 30, the left inclined portion 31 is inclined such that the left side is deep and the right side is shallow, and the depth increases from right to left. On the other hand, the right inclined portion 32 is deep on the right side and shallow on the left side, and is inclined so as to deepen from left to right. The left inclined portion 31 and the right inclined portion 32 are alternately formed in the vertical direction of the pulling groove 30.
As shown in FIG. 11, in the present embodiment, the left inclined portion 31 and the right inclined portion 32 are inclined in a curved shape in the vertical direction. Accordingly, the fingers can be smoothly applied, but the present invention is not limited to this, and the fingers may be inclined linearly. In addition, as shown in FIG. 12, in the present embodiment, the left inclined portion 31 and the right inclined portion 32 are linearly inclined in the horizontal direction, but the present invention is not limited thereto, and may be inclined in a curved shape.

When opening and closing the sliding door 300, when moving it to the left side, a finger is put on the left inclined portion 31, and a force is applied to the left wall surface of the pulling groove 30 to move it. On the other hand, when moving to the right side, a finger is put on the right inclined portion 32 to apply a force to the right wall surface of the pulling groove 30 and move it. Therefore, the part on which the finger is hung is inclined downward toward the moving direction.
Then, in the final stage of movement, as described in the second embodiment, the finger hung on the pulling groove 30 is on the side opposite to the moving direction of the sliding door along the inclination formed in the pulling groove 30. Will be discharged from the pulling groove 30. Thereby, it is possible to prevent fingers from being pinched.

As described above, according to the sliding door 300 according to the third embodiment, in the pulling groove 30, the left inclined portion 31 whose left side is deep and the right side is shallow and the right inclined portion 32 whose right side is deep and the left side is shallow are alternately arranged in the vertical direction. When the sliding door 300 is moved to the left side, the left inclined portion 31 is moved with a finger, and when the sliding door 300 is moved to the right side, the right inclined portion 32 is moved with a finger. it can.
Further, at the final stage of opening the sliding door 300, the fingers are automatically discharged along the inclination of the pulling groove 30, and the hands and fingers are not sandwiched between the sliding door and the wall or between the sliding door and the sliding door.

In the first to third embodiments, the handle grooves are provided on both the front and back surfaces of the sliding door, but may be provided only on either the front surface or the back surface. Similarly, the pulling grooves are provided on both the left and right sides of the sliding door, but may be provided only on either the left side or the right side.
Moreover, although demonstrated using the sliding door which attached the vertical hook to the both sides of the base material, the structure of a sliding door is not limited to this. For example, a single plate material may be used to form a handle groove near the side surface. In short, what is necessary is just to form a pulling groove in the site | part close | similar to the side surface in at least one of the surface of a board | substrate, and a back surface.
Further, the depth of the pull groove is changed from the upper end portion to the lower end portion of the plate material, and the depth of the pull groove at the upper end portion and the lower end portion is shallower than the depth of the pull groove at portions other than the upper end portion and the lower end portion. If formed in this way, the change in depth from the upper end to the lower end is not limited to the above embodiment.
