Description

  The present invention relates to a drawer device such as a table provided in an automobile room.

  In recent years, it has been desired that a notebook computer or the like can be used even in an automobile room. Therefore, it is conceivable to provide a table, but it is preferable that the table can be stored when not in use, and it is considered to arrange a table with a drawer structure.

  For example, Japanese Patent Application Laid-Open No. 2008-037203 and Japanese Patent Application Laid-Open No. 2005-299242 describe a drawer device in which a console lid is slidably held back and forth with respect to a box body. Thus, by making the console lid relatively movable back and forth with respect to the box body, the length can be adjusted according to the body shape when used as an armrest.

  However, in the case of a table with a drawer structure, it is desirable that the tip of the table is flush with the opening end surface of the storage recess when not in use, and it is desirable that the table protrude as long as possible when in use. In use, the space below the table is a space. In this case, the engagement length between the rear end of the table and the storage recess in use is shortened, so that when a load is applied to the table during use, it is necessary to have a structure that can withstand the load.

  Therefore, it is conceivable to use a metal slide member in which the right member and the left member are integrated so as to be relatively movable in the longitudinal direction. If such slide members are respectively arranged at the left and right ends of the table, the load during use is received by the engagement between the right member and the left member, and since it is made of metal, sufficient rigidity is exhibited.

  However, the table body is generally made of resin, and the storage recess is often made of resin. Therefore, the slide movement may not be smooth due to distortion during molding or deformation due to temperature. Furthermore, due to errors in assembling the pair of left and right slide members, the parallel accuracy of the left and right slide members may be reduced, which may cause abnormal noise when the table body is moved in and out, and may cause trouble in slide movement. .

Moreover, it is preferable to automate the movement of the table main body using a biasing member such as a spring. However, in this case, a damper is required to relax the moving speed and give a high-class feeling, and it is necessary to provide a rack for driving the damper. However, the accuracy of engagement between the damper and the rack may decrease due to distortion during molding, assembly error, and the like, and in some cases, the rack and the damper may be separated and the damper may not be driven.

  This invention is made | formed in view of the said situation, and makes it the subject which should be solved to set it as the drawer device with which a slide movement is smooth and a damper is driven reliably.

A feature of the drawer device of the present invention that solves the above problems is a drawer device comprising a storage recess provided in a vehicle interior and a drawer body held in the storage recess so as to be freely accessible.
A slide member in which the right member and the left member are integrated so as to be movable relative to each other in the longitudinal direction is disposed, and one of the right member and the left member is fixed to the storage recess and the other is fixed to the drawer body. The main body is removably held in the storage recess, and the storage recess or the drawer main body is fixed to the slide member in a floating state to absorb distortion,
A biasing member that biases the drawer main body in a direction in which the drawer main body exits or enters the storage recess, and a geared damper that is fixed to one of the storage recess and the drawer main body and relaxes the moving speed of the drawer main body by the biasing member; A rack fixed to the other of the storage recess and the drawer body and meshing with a gear of a geared damper,
One of the rack and the damper with gear absorbs distortion by being fixed to one of the storage recess or the drawer main body in a floating state, and the regulating member protruding from the other of the storage recess or the drawer main body is one of the rack and the geared damper. The contact state between the rack and the geared damper is maintained.

  According to the drawer device of the present invention, since the storage recess or the drawer body is fixed to the slide member in a floating state, the storage recess or the drawer body can be moved relative to the slide member. Strain during molding and strain due to temperature change are absorbed. Accordingly, it is possible to prevent stagnation when the drawer main body is moved in and out, and smooth movement in and out is possible.

  However, if the positional relationship between the drawer main body and the storage recess varies due to fixing in the floating state, it is assumed that the rack and the geared damper are not separated from each other and do not mesh with each other and the damper action is not achieved.

  Therefore, in the present invention, one of the rack and the geared damper is fixed in a floating state so as to be movable in the left-right direction in one of the storage recess or the drawer body, and the regulating member protruding from the other of the storage recess or the drawer body is provided in the rack and The contact state between the rack and the geared damper is ensured by contacting one of the geared dampers. By doing so, the smooth movement of the drawer body can be ensured, the separation of the rack and the geared damper can be surely prevented, and the damper action can be surely produced. Certain operations are ensured.

  The drawer device of the present invention includes a storage recess provided in the vehicle compartment and a drawer body that is held in the storage recess so as to be freely inserted and removed. Examples of the storage recess include a console box, an instrument panel, and a seat back provided in the rear seat. As the drawer body, a table, a cup holder, a box, or the like can be used.

  The drawer device of the present invention uses a slide member in which a right member and a left member are integrated so as to be movable relative to each other in the longitudinal direction. The slide member may be made of resin, but it is desirable to use a metal member in order to be able to receive a large load. In the case of a metal slide member, generally, a rolling member such as a bearing or a roller is interposed between the right member and the left member.

  Further, it is also preferable to use a slide member in which an intermediate member that can move relative to both the right member and the left member is interposed between the right member and the left member. With such a slide member, it is possible to slide more than the total length of the right member and the left member, so that the drawer stroke of the drawer body can be made larger than the storage length of the storage recess.

  One slide member may be arranged at the center of the drawing device or the like, but it is desirable to arrange them on both the left and right sides. By doing so, the movement stability of the drawer body is improved. In the slide member, one of the right member and the left member is fixed to the storage recess, and the other is fixed to the drawer main body, so that the drawer main body is held in the storage recess so as to be freely inserted and removed.

  One feature of the present invention is that the storage recess or the drawer body is fixed to the slide member in a floating state. When a pair of slide members are provided, it is desirable to firmly fix the storage recess and the drawer main body to one slide member. In this way, the relative movement amount of the storage recess or the drawer body and the slide member can be regulated, and the drawer body can be easily moved in and out even during the relative movement of the rack, which will be described later. Can be prevented.

  For example, as shown in the embodiment, on the left side of the drawer body, the right member of the slide member is firmly fixed to the housing recess and the left member is firmly fixed to the drawer body. On the other hand, on the right side of the drawer body, the left member is firmly fixed to the housing recess and the right member is fixed so that the drawer body is in a floating state.

  By doing so, the storage recess or the drawer main body can be moved relative to the slide member, so that distortion during molding of the drawer main body or storage recess, distortion due to temperature change, and the like are absorbed. Further, even when the parallelism of the pair of slide members is slightly low, it is possible to prevent stagnation and to easily move the drawer main body in and out. It is desirable that the slide member is firmly fixed to the storage recess and the drawer body is fixed in a floating state. In addition, in order to fix a slide member in a floating state, it can fix using a stepped volt | bolt, a stepped screw, etc.

  The drawing device of the present invention is provided with an urging member, a geared damper, and a rack. The urging member urges the drawer body in the direction in which the drawer body exits or enters the storage recess, and a coil spring, a leaf spring, or the like can be used. It is desirable to use a constant load spring that always gives the same urging force when moving in and out. As this constant load spring, there is one in which a ribbon-like leaf spring is wound. From the viewpoint of operation feeling, it is preferable that the biasing member biases the drawer body in the direction of exiting the storage recess.

  The rack and the geared damper are respectively fixed to two members that move relative to each other and mesh with each other to relieve the moving speed during relative movement. Therefore, in the drawer | drawing-out apparatus of this invention, a rack is fixed to one side of a storage recessed part or a drawer main body, and a damper with a gearwheel is fixed to the other of a storage recessed part or a drawer main body. However, in the drawer device of the present invention, since the storage recess or the drawer body is fixed to the slide member in a floating state, it is assumed that the rack and the geared damper interfere with each other or do not mesh with each other.

  Therefore, another feature of the present invention is that one of the rack and the damper with a gear is fixed to one of the storage recess or the drawer main body in a floating state so as to be movable in the left-right direction and protrudes from the other of the storage recess or the drawer main body. The restricting member is in contact with one of the rack and the geared damper to maintain the meshing state of the rack and the geared damper.

  One of the rack and the damper with gear is fixed to one of the storage recess or the drawer main body in a floating state so as to be movable in the left-right direction. The rack or the geared damper can be moved relative to the relative movement, and interference can be prevented. The regulating member is brought into contact with one of the rack and the geared damper, so that the rack and the geared damper can always be engaged with each other even if the rack or the geared damper is relatively moved.

  Hereinafter, the present invention will be described specifically by way of examples.

  FIG. 1 shows an overall view of an automobile rear seat console box in which the drawer device of this embodiment is used, and FIGS. 2 to 4 show sectional views thereof. A lid 101 is attached to the console box 100 so as to be swingable about the axis P, and the table 1 is arranged to be able to enter and exit from the front end surface of the lid 101. That is, the table 1 corresponds to the drawer body.

  The lid 101 includes an upper panel 102 and a lower panel 103, and a storage space 2 is formed between the upper panel 102 and the lower panel 103. A resin table 1 is arranged so as to be able to enter and leave the storage space 2 via a slide rail 3.

  The slide rail 3 is a long member made of metal, and is disposed on both the left and right sides of the table 1 as shown in FIG. The slide rail 3 includes a right member 30 having a substantially arc-shaped cross section, a left member 31 having a substantially arc-shaped cross section, an intermediate member 32, and a plurality of balls 33. The balls 33 are respectively disposed between the intermediate member 32 and the right member 30, and between the intermediate member 32 and the left member 31, and the right member 30 and the left member 31 are front and rear with respect to the intermediate member 32 (see FIG. 4). Relative movement is possible in the direction perpendicular to the paper surface.

  A sheet metal member 104 is fixed to the lower panel 103. In addition, metal brackets 105 having an L-shaped cross section are fixed to the left and right sides of the sheet metal member 104, respectively. In the right slide rail 3 in FIG. 4, the left member 31 is fixed to the right metal bracket 105. In the left slide rail 3, the right member 30 is fixed to the left metal bracket 105. Therefore, in the right slide rail 3, the intermediate member 32 can move relative to the metal bracket 105 back and forth, and the right member 30 can move relative to the intermediate member 32 back and forth. Further, in the left slide rail 3, the intermediate member 32 is relatively movable back and forth with respect to the metal bracket 105, and the left member 31 is relatively movable back and forth with respect to the intermediate member 32.

  The right slide rail 3 has a right member 30 fixed to the right end of the table 1, and the left slide rail 3 has a left member 31 fixed to the left end of the table 1. Thus, the table 1 is arranged in the storage space 2 so as to be slidable back and forth via the slide rail 3. The pair of left and right slide rails 3 are respectively positioned below the table 1 and have a structure that is not easily visible when the table 1 is pulled out.

  In this embodiment, the table 1 is firmly fixed to the left slide rail 3 so as not to move, but is fixed to the right slide rail 3 in a floating state. That is, as shown in FIG. 5 in an enlarged manner, the boss 10 having a two-stage through-hole 11 is formed on the table 1 as shown in an enlarged view of the main part of FIG. 4 (attachment portion of the right member 30 of the right slide rail 3). Yes. The diameter of the through hole 11 is increased at the tip of the boss 10, and a step 12 is formed in the boss 10.

  A flange 34 extends rightward from the right member 30 of the right slide rail 3, and a stepped screw 35 is fixed to the boss 10. The stepped screw 35 is prevented from entering further at the position where it abuts against the stepped portion 12, and the flange 34 has a gap W of 0.2 mm between the head of the stepped screw 35 and the tip surface of the boss 10. It is held in a floating state.

  By doing so, the table 1 can be slightly moved in the vertical and horizontal directions with respect to the right slide rail 3. Therefore, even if molding distortion exists in the table 1 or the parallelism of the pair of slide rails 3 is low, the error can be absorbed by the gap W, and the table 1 can be stably slid back and forth. It becomes possible.

  A heart cam (not shown) is formed at the rear portion of the table 1, and a push lock can be opened by engaging and disengaging a pin (not shown) extending from the lower panel 103. A spring device 4 is held at the rear of the table 1. As shown in FIG. 4, the spring device 4 includes a bobbin 40 and a plate spring 41 wound around the bobbin 40, and the bobbin 40 is rotatably held on the table 1. The tip of the leaf spring 41 is fixed to the lower panel 103 near the opening of the storage space 2 as shown in FIG. Therefore, in the use position (see FIG. 3) in which the table 1 is pulled out from the storage space 2, no urging force is generated in the spring device 4. On the other hand, in the storage position where the table 1 is stored in the storage space 2 and the pin (not shown) protruding from the lower panel 103 is engaged with the heart cam (not shown), the leaf spring 41 extends, so that the spring device 4 has the table 1 Is stored in the direction of exiting the storage space 2.

  A geared damper 5 is fixed to the rear portion of the table 1. As shown in FIG. 6, the geared damper 5 includes a damper portion 50 and a gear 51, and the rotation of the gear 51 is restricted by the viscous resistance of the fluid held in the damper portion 50. A sheet metal member 104 is fixed to the lower panel 103, and a long rack member 6 is held on the sheet metal member 104. The rack member 6 has rack teeth 60 extending in the front-rear direction, and the rack teeth 60 mesh with the gear 51. Therefore, when the table 1 slides in the front-rear direction, the rack member 6 rotates the gear 51 to generate resistance in the damper portion 50, and the moving speed of the table 1 is delayed, so that a high-class feeling can be obtained.

  Here, as shown in FIG. 6, the rack member 6 is held so as to be slightly movable in the left-right direction with respect to the sheet metal member 104. That is, the convex portion 61 protruding from the rack member 6 engages with the long hole 106 formed in the sheet metal member 104, and a gap Z is formed in the left-right direction between the convex portion 61 and the long hole 106. On the other hand, a rib 13 projecting downward from the table 1 is in contact with the right side surface of the rack member 6 so that the gear 51 and the rack teeth 60 are engaged with each other.

  Accordingly, even when the table 1 is displaced in the left-right direction due to the gap W, the rack member 6 can be moved relative to the sheet metal member 104 in the left-right direction by the gap Z to absorb the position deviation. it can. Further, since the state in which the gear 51 and the rack teeth 60 are engaged with each other by the ribs 13 is maintained, even if the rack member 6 moves in the left-right direction, the gears 51 and the rack teeth 60 are reliably engaged with each other, and the damper operation is reliably performed. Played.

  When pulling out the table 1 from the storage position, the front end surface of the table 1 is pushed with a finger, and the table 1 is pushed into the storage space 2 for a predetermined length. Then, the engagement between the heart cam (not shown) and the pin (not shown) is released, and the table 1 is automatically ejected from the storage space by the urging of the spring device 4. When the table 1 is stored in the storage space 2 from the use position, the table 1 is pushed into the storage space 2 against the biasing force of the spring device 4, and the heart cam (not shown) and the pin (not shown) are engaged. The storage state is fixed by.

  When the table 1 moves in and out, various dimensional errors are absorbed by the relative movement of the table 1 by the gap W and the relative movement of the rack member 6 by the gap Z. Therefore, the table 1 can be stably put in and out without being squeezed by the smooth sliding movement of the slide member 3. Further, when the table 1 moves in the direction of exiting the storage space 2, the geared damper 5 is reliably operated by the rack member 6, and the table 1 slowly comes out of the storage space, so that a high-class feeling can be obtained. Further, when the table 1 moves in the direction of entering the storage space 2, the geared damper 5 is reliably operated by the rack member 6, and a slight resistance is perceived, so that a feeling of weight (a sense of quality) is felt and the spring device 4. The urging power is stored in and is prepared for the next use.

  In the above-described embodiment, the present invention is applied to the console table in the rear seat of the automobile, but it goes without saying that the present invention can be applied to various drawer devices such as a cup holder device and an ashtray device.
