Drive support structure for drawer in storage box

Technical field

[0001] The present invention relates to a technique for pulling a drawer body out of a storage box and moving it in a storage direction by a driving means when a drawer body long in the left-right direction is attached to the storage box so as to be pulled out and stored. is there.

Background art

[0002] A long storage box is installed on the top of the furniture to store a long screen in the left-right direction, and the front of the storage box protrudes forward from the front of the top of the furniture. It is known from the publication 20876. This furniture usually picks up a screen and stores it in a storage box. When a projector is used as a home theater, the screen is pulled down and an image is projected onto the screen by the projector.

However, in this conventional example, the front part of the storage bot that winds and stores the screen always projects forward from the front surface of the upper part of the furniture, and from the lower opening of the storage box. There was a problem that the appearance was bad because the screen stored inside was visible

[0004] Therefore, in order to improve the appearance, the inventor of the present invention, in the process leading to the present invention, attaches a drawer body that is long in the left-right direction to a storage box such as furniture, so that it can be stored freely. Store the screen in the drawer body, pull the drawer body forward when pulling the screen downward, and retract the drawer body and store it in the storage part of the storage box when winding the screen and storing it in the drawer body Then, we considered to prevent the drawer body from protruding forward when the drawer body is not used (that is, when the screen is not used).

[0005] Specifically, in order to allow the drawer body that is long in the left-right direction to be pulled out and stored, the left and right ends are driven by separate driving means, respectively, I thought about moving it in the storage direction.

[0006] However, in that case, since the driving means are provided on the left and right respectively, the overall size is increased and the cost is increased. Also, the drawer body that is long in the left-right direction is different from the normal drawer in that If the left / right balance of the drawer that is long in the left / right direction is lost during operation and storage, the drawer cannot be pulled out or stored smoothly. It was difficult to adjust, and it turned out that there was a problem. In addition, since the drive means are provided on the left and right, the assembly and maintenance are poor. In addition, if the structure is such that the driving force of the driving means is transmitted directly to the left and right ends of the drawer body, the drive transmission mechanism must be assembled at the same time when the drawer body is assembled into the storage part of the storage box. Was found to be extremely troublesome. Furthermore, if the length of the drawer body in the left-right direction is different, it is difficult to easily cope with it.

Disclosure of the invention

[0007] The present invention has been made to solve the above-mentioned problems, and with a simple configuration, a drawer body that is long in the left-right direction can be pulled out and stored while balancing left and right. A single drive means is sufficient for downsizing and low cost. In addition, assembly and maintenance are easy, and the drawer body can be easily accommodated when the left and right lengths are different. It is an object to provide a drive support structure for a drawer in a box.

[0008] In order to solve the above problems, the drive support structure of the drawer body in the storage box according to the present invention is such that the drawer body 2 can be pulled out from the storage box 1 in the front-rear direction via the drive block 3 and stored freely. The drive block 3 is mounted on the movable base 4 attached to the middle part of the drawer body 2 in the left-right direction, and the drawer 2 in the storage box 1 is retractably stored. Parallel to the pull-out direction of the drawer body 2 provided on either the left or right side of the fixed base 6 and the moving base 4 or the fixed base 6 attached to the middle part in the left-right direction of the part 5 A guide rail 7 that is long in any direction, a horizontal wheel 8 that is provided on both the left and right sides of the other side of the moving base 4 or the fixed base 6 and that is movable with respect to the guide rail 7, and left and right Each horizontal wheel 8 that can run freely on the guide rail 7 Pressing means 10 for pressing against the side wall 9 of the right guide rail 7, driving means 11 provided on the fixed-side base material 6, and moving-side base material 4 to which the driving force of the driving means 11 is transmitted The transmission unit 12 is provided.

With such a configuration, even if the drawer body 2 is long in the left-right direction, the drawer body 2 is moved forward with respect to the storage box 1 by the drive block 3 attached to the middle part in the left-right direction. It can be moved out and pulled out, or moved backward and stored. Also, since only one drive block 3 is required, the structure is simple, the size can be reduced, and the cost can be reduced. Even though the drawer body 2 is pulled out and stored by one drive means 11 provided in one drive block 3 attached to the middle part in the left and right direction, the left and right guide rails 7 have side walls 9 respectively. Since the horizontal wheel 8 is configured to be pressed by the pressing means 10, it prevents rattling of the drawer body 2 in the left-right direction, and thereby the left-right direction while balancing the left and right of the drawer body 2 that is long in the left-right direction. The long drawer body 2 can be moved smoothly forward and backward. Furthermore, the stationary base 6 of the drive block 3 is attached to the storage box 1 at the intermediate portion of the storage 5 of the storage box 1 in the horizontal direction, and the moving base 4 of the drive block 3 is mounted in the horizontal direction of the drawer body 2. By simply attaching it to the middle part of the thread, you can easily take up the thread. In addition, since the drive block 3 is provided at one place in the middle portion in the left-right direction, maintenance can be performed easily at one place. In addition, since the drive block 3 only needs to be attached to the middle of the drawer body 2 and storage part 5 in the left-right direction, the same type of drive block 3 can be used even if the length of the drawer body 2 and storage part 5 in the left-right direction is different. It can respond.

[0010] Preferably, the driving force of the driving means 11 provided on the fixed-side base 6 is transmitted to the transmitting portion 12 provided on the moving-side base 4 via the drive transmitting means 13, and the drive transmitting means 13 is transmitted. The first and second drums 15a and 15b rotated by the motor 14 constituting the driving means 11, the pulley 16 provided on the stationary side substrate 6, and one end portion fixed to the first drum 15a and wound. In addition, the first belt 17a is wound around the pulley 16 and the other end is fixed to the transmission unit 12, and one end is fixed and wound around the second drum 15b, and the other end is moved to the moving base 4 A second belt 17b fixed to the transmission portion 12 provided in the first belt 15b, and a direction in which the first belt 17a is wound around the first drum 15a and a direction in which the second belt 17b is wound around the second drum 15b. The transmission belt 12 is pulled when the first belt 17a is wound around the first drum 15a by the forward rotation of the motor 14 in the reverse direction. As the second belt 17b is pulled out from the second drum 15b and the second belt 17b is wound around the second drum 15b by the reverse rotation of the motor 14, the transmission unit 12 is pulled in the reverse direction and the first belt 17a Is configured to be drawn from the first drum 15a.

[0011] In this case, the moving side base 6 is moved relative to the fixed side base 6 simply by rotating the motor 14 forward or backward with a simple configuration compared to a screw feed mechanism or a rack pion mechanism. Material 4 Can be moved in the front-rear direction to move the drawer body 2 in the pull-out direction, or moved in the storage direction.

[0012] In addition, the second belt 17b is slackened when the transmission unit 12 is pulled by the first belt 17a, and the first belt 17a is slackened when the transmission unit 12 is pulled by the second belt 17b. Preferable to configure.

[0013] In this case, it is possible to provide a margin for the starting torque when the motor 14 rotates forward or backward.

[0014] Preferably, detection means 18 for detecting the drawer position and the storage position of the drawer body 2 is provided, and the detection means 18 is provided on the storage box 1 side to stop the drive of the drive means 11. The limit switch 19 and the operating part 20 provided on the drawer body 2 side to operate the limit switch 19 are configured so that the mounting position of the operating part 20 in the moving direction of the drawer body 2 can be adjusted.

In this case, by adjusting the mounting position of the operating portion 20 in the front-rear direction, the drawer length of the drawer body 2 and the storage depth of the drawer body 2 in the storage section 5 can be easily adjusted. Thereby, it is possible to easily achieve the optimum drawer length and the optimum storage depth (for example, the storage depth such that the front surface of the drawer body 2 and the front surface of the storage button 1 are flush with each other).

[0016] Preferably, the drawer body 2 is composed of a main body portion 21 and a door plate 23 attached to the front side of the front plate 22 of the main body portion 21, and is opened upward and frontward and rearward at the upper end portion of the front plate 22. A U-shaped groove portion 24 having a U-shape is formed and a vertically long hole 25 is formed in the lower portion, and a temporary fixing and fixing screw 26 screwed to the upper rear surface of the door plate 23 is inserted and fixed into the U-shaped groove portion 24 from above. At the same time, a fixing screw 27 inserted into the vertically long hole 25 is screwed to the door plate 23.

[0017] In this case, when attaching the door plate 23 to the front plate 22 of the main body 21, the rear upper portion of the door plate 23 is temporarily attached to the upper portion of the door plate 23 with the temporary fixing and fixing screws 26 temporarily attached.

The front roller 28 and the rear roller 29 may not be able to move smoothly due to the contact between the lower surface of the lower side piece 31 and the upper surface of the lower horizontal piece 31 and the movement of the drawer body 2 in the front-rear direction becomes worse. The rail member 30 may not enter the rail member 30 or may not be kept horizontal. Therefore, as described above, the distance between the lower horizontal piece 31 and the upper horizontal piece 32 of the rail member 30 is set larger than the diameters of the front roller 28 and the rear roller 29, and the drawer body 2 is drawn forward. In this state, the front roller 28 presses the upper surface of the lower horizontal piece 31 of the rail member 30 that is substantially U-shaped, and the lower roller 32 of the rail member 30 that has the substantially U-shaped rear roller 29 touches the lower surface of the upper horizontal piece 32. By configuring so as to be in press contact, the drawer body 2 can move smoothly in the front-rear direction, and the front roller 28 and the rear roller 29 can be inserted into the rail member 30 even if there are variations in each part. In addition, the position of the front roller 28 attached to the drawer body 2 is set to a position lower than the position of the rear roller 29 attached to the drawer body 2, and the front roller 28 is substantially connected with the drawer body 2 pulled forward. The drawer member 2 is pulled out by being pressed against the upper surface of the lower horizontal piece 31 of the rail-shaped member 30 and the rear roller 29 being pressed against the lower surface of the upper horizontal piece 32 of the substantially U-shaped rail member 30. It becomes possible to keep the level when hitting.

For example, if the forward rotation direction of the motor as the driving means 11 is the direction in which the first belt 17a is wound around the first drum 15a, the direction in which the second belt 17b is wound around the second drum 15b is the reverse rotation of the motor. It has become a direction. Therefore, when the motor as the driving means 11 is rotated forward, the first belt 17a is wound around the first drum 15a, and the transmission portion 12 is pulled in the direction of the arrow α in the figure, and the second belt 17b is Pulled out from the drum 15 b, the moving side base material 4 moves in the forward direction with respect to the fixed side base material 6. When the open detection limit switch 19a is actuated by the opening detection actuating portion 20a, the motor stops. In addition, the reverse rotation of the motor 14 causes the second belt 17b to be wound around the second drum 15b and the transmission unit 12 to be pulled in the reverse direction, while the first belt 17a also pulls out the force of the first drum 15a. The base material 4 moves relative to the fixed-side base material 6 in the backward direction, which is the arrow j8 direction in FIGS. 10A and 10B. When the closing detection limit switch 19b is actuated by the closing detection operating unit 20b, the motor stops.

To fix the other end of the first belt 17a having one end fixed to the first drum 15a to the transmission portion 12, and to fix the other end of the second belt 17b having one end fixed to the second drum 15b to the transmission portion 12. In this case, the first belt 17a and the second belt 17b are fixed so as to be slightly loosened. As a result, the second belt 17b is slack when the transmission portion 12 is pulled by the first belt 17a, and the first belt 17a is slack when the transmission portion 12 is pulled by the second belt 17b. It ’s like that. In other words, the second belt 17b is slightly loosened in a state in which the transmission unit 12 is pulled by the first belt 17a to move the moving-side base material 4 forward and stopped. Therefore, the motor rotates in the reverse direction and the second belt 17b starts to be wound around the second drum 15b. At the initial stage, the second belt 17b is slightly stagnant, so that the motor is compared with the case where the belt is tensioned from the beginning. The second belt 17b can be wound with a small starting torque with a sufficient starting torque. On the other hand, the first belt 17a is slightly loosened in a state in which the transmission unit 12 is pulled by the second belt 17b and the moving-side base material 4 is moved rearward and stopped. Therefore, the motor is rotated forward to start winding the first belt 17a around the first drum 15a. In the initial stage, the first belt 17a is slightly stagnant, so that the starting torque of the motor can be afforded compared to the case where the belt is tensioned from the beginning, and the first belt 17a can be wound with a small starting torque. become. Here, when the rotary shaft 59 on which the second belt 17b is hung is mounted on the drive means fixing base 42 and mounted, if the mounting position is adjustable, the amount of slack can be easily adjusted.

[0042] As shown in Figs. 6 and 14, the drive block 3 having the above-described configuration has the stationary base 6 fixed to the top surface portion of the intermediate portion in the left-right direction of the storage portion 5 of the storage box 1 by a fixing tool. Is done. After that, as shown in FIG. 1, the front roller 28 and the rear roller 29 provided on the left and right sides of the drawer body 2 are fitted to the rail members 30 provided on the left and right sides of the storage portion 5 of the storage box 1 so as to be freely rollable. In addition, the drawer body 2 is pulled forward with respect to the storage box 1, and the moving base 4 is pulled forward with respect to the stationary base 6. In this state, the moving base 4 is pulled out. In the middle in the left-right direction, the fixing plate 39 is fixed to the fixing hole 39 provided in the horizontal plate 36 (see FIG. 7) with a screw. As a result, the intermediate part in the left-right direction of the drawer body 2 is attached to the storage box 1 via the drive block 3.

[0043] After the drawer body 2 is attached to the storage box 1 as described above, the front opening of the rail member 30 of the storage box 1 is closed by a stopper plate (not shown) so that the front roller 28 is the rail member 30. So that it does not come forward.

[0044] In addition, the force required to attach the door plate 23 to the front plate 22 of the drawer body 2 When installing the door plate 23, as shown in FIG. While the set screw 26 is temporarily attached, the temporarily set screw 26 screwed to the upper back of the door plate 23 is inserted into the U-shaped groove 24 from above, and in this state, the door plate 23 is attached to the front plate 22. Adjust the position in the vertical direction, insert the fixing screw 27 from the vertically long hole 25 and screw it to the door plate 23 to fix it. As a result, when attaching the door plate 23 to the front plate 22 of the drawer body 2 that is long in the left-right direction, when the drawer body 2 is stored in the storage section 5, the door plate 23 closes the front opening of the storage section 5 tightly. The installation position of the door plate 23 that is long in the left-right direction can be adjusted.

The storage box 1 is provided with a remote control receiving unit 52 (see FIG. 13B). By operating a remote control (not shown), the control unit 43 rotates the motor as the driving means 11 in the normal direction. The drawer body 2 that is controlled and fixed to the moving-side base material 4 is pulled forward. When the opening detection actuating portion 20a activates the opening detection limit switch 19a, the motor as the driving means 11 stops, and then the screen driving motor is driven to lower the screen 51, along the front surface of the furniture 33. It hangs down and covers the television storage section 34a of the furniture 33 as shown in FIG. 13B.

In this state, as shown in FIG. 13C, an image can be projected on the screen 51 from the projector 54 installed in the room, and a home theater can be enjoyed.

When the projector 54 is not used, by operating the remote controller, the control unit 43 reversely rotates the screen drive motor, lifts the screen 51 while winding it, and stores it in the screen storage recess 55. Next, the motor which is the driving means 11 rotates forward, and the drawer body 2 moves backward. When the closing detection actuating part 20b activates the closing detection limit switch 19b, the motor as the driving means 11 stops and the drawer body 2 is stored in the storage part 5, and the front side of the drawer body 2 as shown in FIG. The door plate 23 is flush with the front of other parts of the storage box 1.

[0048] When the drawer body 2 that is long in the left-right direction is moved in the front-rear direction by the drive means 11 as described above, the drawer body 2 is placed in the storage box 1 by the drive block 3 provided in the middle portion of the drawer body 2 in the left-right direction. On the other hand, it can be moved forward and pulled out, or moved backward and stored, so only one drive block 3 is required. Therefore, the structure is simple and the size can be reduced as compared with the case where a plurality of drive blocks 3 are provided, the assembly is simple, and the maintenance is good at one place.

[0049] In addition, since the horizontal wheels 8 are pressed against the side walls 9 of the left and right guide rails 7 by the pressing means 10, respectively, rattling of the drawer body 2 in the left-right direction can be prevented. It is long in the left-right direction, and the drawer body 2 that is long in the left-right direction can be smoothly moved in the front-rear direction while balancing the left and right of the drawer body 2.

[0050] Further, if the length of the screen 51 in the left-right direction is different, the length of the drawer body 2 is also different. The drive block 3 has only to be attached to the middle part of the drawer body 2 and the storage part 5 in the left-right direction. Even if the length of the drawer 2 is different, the same type of drive block 3 can be used.

[0051] In the embodiment shown in the accompanying drawings, the drawer body 2 that is long in the left-right direction is long. A force showing an example of providing a screen storage recess 55 that is long in the left-right direction for winding and storing the screen 51. Not limited to the one provided with the screen storage recess 55, but left and right for storing other things. Needless to say, it may be long in the direction and provided with a storage section. Also in this case, the drawer body 2 that is long in the left-right direction can be smoothly moved in the front-rear direction while balancing the left and right.
