  The present invention relates to a leg module for a sheet metal drawer and a sheet metal drawer using the same, and in particular, in the sheet metal drawer operation, the width of the seating member of the sheet metal drawer serving as a fulcrum of the sheet metal drawer is adjusted in a wide range and freely. The present invention relates to a leg module for a sheet metal drawer and a sheet metal drawer using the same.

  In recent years, as a method for easily and quickly restoring a dent generated in a metal plate material, for example, an automobile body (vehicle body panel) that has been dented due to an accident or the like, the dent can be removed from the outside of the vehicle body panel using various sheet metal drawers. The method of pulling out is performed. According to such a method, it is possible to perform the repairing process only on the front surface side of the recessed portion without exposing the back surface of the recessed portion to be repaired, and the working time can be greatly shortened.

  Conventionally, as a sheet metal drawing tool (puller) used in such a repair method, generally, a welding tip for welding electrodes (also referred to as a welding tip) is provided at the tip of the rod, or a hook is used as a rod. The thing etc. which were provided in the front-end | tip of are provided.

  Among these, in the drawing tool provided with the welding tip, after welding the welding tip to the recessed portion of the body panel to be repaired, the rod is pulled to relieve the dent, and in the drawing tool provided with the hook, A hook is hooked directly or indirectly on a washer or a perforated pin welded to a sheet metal surface, and the rod is similarly pulled to ease the dent.

  Patent Documents 1 to 4 exist as prior literature on such a sheet metal drawing tool or puller.

  In Patent Document 1 (Japanese Patent Laid-Open No. 7-303920), a grip width adjusting means for adjusting the grip width between the main lever and the second lever is adjusted so that the grip width of the operation means can be adjusted to a grip width suitable for the operator. In this document, it is also proposed that the left and right legs of the leg are made independent and the positions of the left and right legs are moved (Patent Document 1). FIG. 11).

  Further, in Patent Document 2 (Japanese Patent Application Laid-Open No. 2004-154855), adjustment of the protruding amount of the spot welding electrode rod is performed simply, accurately and quickly, and the rotation position of the stand member according to the state of damage of the damaged portion. In order to be able to easily and quickly change or replace the spot welding electrode rod, the projection amount adjusting means for adjusting the projection amount of the spot welding electrode rod toward the temporary welding site, and the temporary welding site of the spot welding electrode rod after the temporary welding There has been proposed a puller for repairing a dent in a metal plate material, which includes a lifting amount adjusting means for adjusting a lifting amount in a direction opposite to the direction, and further includes a plurality of types of stand members having different sizes and shapes (Patent Document) Figure 3).

Moreover, although patent document 3 (Unexamined-Japanese-Patent No. 2002-205115) proposes preventing the excessive drawing | extracting of a concave surface, in this literature, the drawer tool suitable for a construction location is selected as a drawer auxiliary tool. By combining them efficiently, the recessed portion can be efficiently drawn out.
JP-A-7-303920 JP 2004-154855 A JP 2002-205115 A

  As described above, a large number of sheet metal drawing tools have been proposed in the past, and in Patent Document 1 and Patent Document 2, the size of the stand member and the right and left abutting member members are matched to the size of the recess. There has also been proposed a sheet metal drawing tool capable of adjusting the interval.

  However, the conventionally provided stand member of the sheet metal drawing tool has only a function as a fulcrum at the time of the drawing work, and the drawing width of the recessed sheet metal surface or the degree of drawing cannot be adjusted.

  Therefore, in the present invention, firstly, in the operation of pulling out the recessed sheet metal surface, it does not only function as a fulcrum, but also adjusts its pull-out amount to prevent overdrawing of the sheet metal surface. It is an issue to provide.

  Here, when considering the dent of the body panel to be repaired again, the shape (planar shape) of the dent is a straight line, is complicatedly recessed in a certain region, or is depressed while being twisted and bent. There are also various kinds of dents, and the degree of dents varies from a wide range to a narrow area.

  However, the stand part of the sheet metal drawer described in Patent Document 1 is not sufficient in length even if the width can be adjusted, so that it is suitable for repairing a slightly larger dent. Not. In other words, when trying to repair a slightly larger dent using the stand part in the conventional sheet metal drawing tool, the stand part itself exists in the dent, and as a result, in the dent, A part of them is pulled up (or pulled out), and an effective pulling out operation cannot be performed. Also, when trying to pull out a sheet metal surface that has been recessed with a conventional sheet metal drawing tool, the pull-out area is limited from the pull-out point to the area where the stand member abuts, so a wide range of dents are repaired. To do this, the sheet metal drawer must be moved / installed at many points, which is complicated.

  Accordingly, the present invention provides a sheet metal drawer tool leg module capable of efficiently repairing a concave portion in a relatively large area, and a sheet metal drawer tool using the same. It is.

  In order to solve the above-described problems, in the present invention, first, a sheet metal drawing tool in which a contact member that abuts on a sheet metal surface is formed in a long shape, and the contact member is arranged in parallel so that the interval can be adjusted. A leg module is provided.

That is, the leg module for a sheet metal drawer according to the present invention is a leg module for a sheet metal drawer that is used by being attached to a sheet metal drawer for pulling out a sheet metal surface, and is arranged in parallel to abut against the sheet metal surface. Two long (such as bar-shaped) seat members, a connecting member installed between the seat members , and a fixing member for attaching the leg module to the sheet metal drawer. The seat members are formed so that the distance between them can be adjusted.

  The abutting seat member is a portion that comes into contact with the sheet metal surface when the sheet metal surface is pulled out by the sheet metal drawing tool, and is formed in a long shape in the present invention. Here, the long shape is at least 20 cm or more, preferably 25 to 50 cm. The size of the dent that can be repaired increases depending on the length of the abutment portion, but is preferably 60 cm or less in consideration of the drawing amount by the sheet metal drawing tool and workability.

  Such a seat member can be formed as a linearly formed rod body or a curved or bent rod body, and can be appropriately formed into a three-dimensional shape without being limited to the rod body. However, since this abutting seat member is in contact with the sheet metal surface, at least its bottom surface (surface in contact with the sheet metal surface) needs to be formed flat. And two this seats are used and are arranged in parallel to each other.

  The connecting member plays a role of connecting the abutting seat members to each other and / or a role of connecting the abutting seat members to the fixing member, and further, a structure or a structure capable of adjusting a distance and a posture between the two abutting seat members. It is formed as a member. Such a connecting member may be embodied as a shaft-like member having a telescopic structure in addition to a frame-like member connected to each abutment member by a turning pair (that is, a rotatable connection). it can. Here, the expansion / contraction structure is a combination configuration of two shaft-like bodies (including a plate-like body), and one shaft-like body is used as an internal space of another shaft-like body like a combination structure of a cylinder and a piston. Also included are those that can be accommodated, or those in which two shafts are connected by screws or other fasteners so that the length can be adjusted.

  The fixing member is for attaching the sheet metal drawing tool leg module to the sheet metal drawing tool, and is formed with at least a fixing part assembled to the sheet metal drawing tool. However, this fixing member should be appropriately selected according to the combination structure of the sheet metal drawing tool to be used. For example, when the sheet metal drawing tool side is formed in a structure that engages the shaft, the fixing portion in the fixing member is formed in a shaft shape.

  According to the leg module for a sheet metal drawing tool configured as described above, since the seat member is formed long, the possibility that the seat member is present in the recess can be eliminated as much as possible. I can do it. Furthermore, if the dent is smaller than the length of the abutment member, it is possible to efficiently remove the sheet metal drawer by moving the most concave part or the part to which external force is applied when the dent is indented. The sheet metal surface can be pulled out. Further, if the dent is smaller than the length of the abutment member, the abutment portion exists on the sheet metal part (normal sheet metal surface) that is not recessed. By using the height up to the index or until the raised sheet metal surface contacts the bottom surface of the abutting seat member, it is possible to prevent the recessed sheet metal surface from being pulled out excessively. Considering that the excessive withdrawal of the concave sheet metal surface is the biggest problem that prevents the efficiency of the drawing operation of the sheet metal surface, the effect of preventing the excessive withdrawal of the sheet metal surface is the work efficiency. Has a great effect.

  In the leg module for a sheet metal drawer according to the present invention, the connecting member is provided at two locations in the length direction of the two long abutment members, and the two connecting members and The two long abutment members are preferably formed as a four-bar rotating chain mechanism in which all pairs are turned and combined in pairs. If formed in this way, when the connecting member is swung with respect to any one of the seat members, the other seat member functions as a connecting rod, and the two long seats The distance between the members can be adjusted. By adjusting the distance between the seat members using the link mechanism, the operability (adjustment of the distance between the seat members) during work can be improved.

  In addition, the connecting member is attached to the fixed member by a pair of turns, and at least one of the pair of turns of the connecting member and the fixed member and the pair of turns of the connecting member and the seat member is turned around. It is desirable to provide a connecting fixture that prevents rotation at the kinematic pair. As such a connecting fixture, the connecting member and the fixing member or the abutting member and the connecting member are formed as a fixing tool for detachably fixing, and the connecting member and the fixing member or the abutting member and the rotation at the connecting portion of the connecting member. It can be formed as a fixture that adheres and fixes the two together. By installing such a connection fixture, the distance between the seat members can be kept constant during the pulling operation, so that an effect that it is easy to work can be achieved.

Further, in the leg module for a sheet metal drawer according to the present invention, the two connecting members and the two elongated seat members form a rectangular or rhombus region, and the fixing member is the sheet metal drawer. It is desirable that the sheet metal lead-out portion is formed at a position where it exists in the rectangular region. That is, in the above example, when the two abutting seat members and the two connecting members provided so that the abutting seat members intersect with each other, the drawer portion of the sheet metal drawer is the two In order to be able to attach this sheet metal drawer tool leg module to the sheet metal drawer tool so as to exist in a rectangular or rhombus region formed by the connecting member and the two elongated contact seat members , It is desirable that the fixing member is formed.

Further, in the leg module for a sheet metal drawer according to the present invention, the connecting member is provided at two locations in the length direction of the two long-sided seat members , and the connecting members are It is desirable that the mounting member is rotatably attached to a fixing member having a fixing part fixed to the sheet metal drawer.

  By having such a configuration, it becomes possible to set the length of the connecting member, that is, the interval between the abutting seat members regardless of the positional relationship of the attachment portion of the sheet metal drawing tool. The interval between the seat members can be set freely. As a result, it is possible to increase the interval between the seat members that come into contact with the sheet metal surface. Here, when the recessed sheet metal surface is pulled out, the contact portion with the sheet metal surface in the leg portion (the drawing point) centered on the point (drawing point) pulled out by the drawer shaft of the sheet metal drawing tool, etc. ) Is pulled out, but a wider area can be pulled out by a single pulling operation by increasing the spacing between the seat members as in the present invention. Therefore, even if it is a moderate dent that has been considered difficult to pull out a sheet metal so far (indentation of a degree called a halfway in the industry), without frequently moving the sheet metal drawer, It becomes possible to repair very easily.

  And in this invention, in order to solve at least 1 of the above-mentioned subject, as mentioned above, the leg module for sheet metal drawers which has two long-like (bar shape etc.) application seat members arranged in parallel, Provided is a leg module for a sheet metal drawer that can be pivotally attached to a sheet metal drawer.

  That is, a leg module for a sheet metal drawer that is used by being attached to a sheet metal drawer for pulling out the sheet metal surface, and is applied with two long (bar-shaped) contacts arranged in parallel and in contact with the sheet metal surface. It comprises a seat member and a fixing member for fixing the seat member to the sheet metal drawer, and the fixing member is rotatable about an axis perpendicular to a horizontal plane in which two elongated shapes exist. It is the leg part module for sheet metal drawers provided.

  By mounting at least the abutment part of the leg module for the sheet metal drawer to the sheet metal drawer so that the handle of the sheet metal drawer is not unnatural, workability is improved. Can be further improved. Assuming that the mounting position of the abutment portion and the sheet metal drawing tool is constant, the sheet metal drawing tool may be changed or an unnatural posture is forced depending on the orientation of the placement seat portion. Therefore, the point that the seat portion can be freely rotated with respect to the sheet metal drawing tool is also advantageous in actual work.

  Further, the present invention provides a leg module for a sheet metal drawer that can be exchanged arbitrarily by preparing a plurality of a pair of abutting seat members that are in contact with the sheet metal surface and formed in a bar shape.

  That is, a leg module for a sheet metal drawer that is used by being attached to a sheet metal drawer for pulling out the sheet metal surface, and is fixed to the sheet metal drawer and a seating member formed in a bar shape that contacts the sheet metal surface. And a connecting member that attaches the leg to the fixing member, and the seat member is a leg module for a sheet metal drawer that is detachably attached to the connecting member.

  Such replacement of the seat member is effective, for example, when the contact area with the sheet metal surface is changed or when the strength of the seat member itself needs to be changed. In particular, as means for changing the strength of the abutting member itself, it is effective to prepare several sets of abutting members having different materials and thicknesses, and to prepare several sets of abutting members having different lengths. In particular, when two sets of abutment members having different lengths are prepared, it can be configured as follows.

  That is, a leg module for a sheet metal drawer used to be attached to a sheet metal drawer for pulling out a sheet metal surface, and a long fixing member fixed to the sheet metal drawer, and a longitudinal direction of the fixing member And a pair of seating members that are detachably provided on the coupling member and are in contact with the sheet metal surface. The member is connected to the two connecting members, or is a sheet metal drawer tool leg module provided for each connecting member.

  That is, two types of seating members having different lengths are prepared, a pair of seating members formed in a long shape are provided to be connected to two connecting members, and a pair of seating members formed short are Each is provided on each connecting member.

  If formed in this way, not only the strength of the abutting member itself can be changed, but also the posture between the abutting members can be adjusted in various ways, so that it matches the situation and location of the sheet metal surface to be pulled out or the shape of the recess Thus, the posture between the seat members can be freely changed. As a result, the sheet metal surface can be pulled out while holding the abutment member in an optimum posture.

  In particular, it is desirable that the connecting members installed at two places in the length direction of the fixing member formed in a long shape are provided so as to be rotatable with respect to the fixing member, and the two connecting members are respectively At intervals that do not interfere with each other when they rotate, preferably at intervals that ensure a clearance of 1 cm or more between the seat members even when the seat members attached to the connecting members are arranged in a straight line Therefore, it is desirable that the fixing member be provided.

  And in this invention, in order to solve at least 1 of the above-mentioned subject, the drawer tool for sheet metal comprised using the said leg part module for sheet metal drawers is provided.

  That is, a base frame provided with a leg portion that comes into contact with the sheet metal surface, and a shaft that is provided so as to be movable forward and backward with respect to the base frame and provided with a connection tool with the sheet metal surface at the tip, The above-described leg module according to the present invention is used, and the shaft is present between the seat members constituting the leg module.

  According to such a sheet metal drawing device, since it is configured with the leg module according to the present invention, it is possible to eliminate the possibility that the seat member is present in the recess as much as possible. If the dent is smaller than the length of the seat member, it is possible to efficiently extract the sheet metal without having to move the sheet metal drawer many times by pulling out the most recessed part or the part to which external force is applied when it is recessed. The surface can be pulled out. Further, when pulling out the recessed sheet metal surface, the height of the corresponding seat member is used as an index, or by pulling out until the raised sheet metal surface hits the bottom surface of the seat member, it is possible to prevent the recessed sheet metal surface from being pulled out excessively. Can be prevented. Furthermore, even when repairing an intermediate dent, the sheet metal drawing tool can be repaired without being moved frequently.

  In the sheet metal drawing tool, it is desirable that the leg portion is attached to the base frame so as to be able to advance and retreat, and the attachment portion of the leg portion of the base frame is at least in the axial direction of the leg portion with respect to the base frame. It is desirable to provide a lock mechanism that prevents movement. By attaching the leg part to the base frame so as to be able to move forward and backward, the length of the leg part can be adjusted, and a panel is provided by providing a lock mechanism for preventing the leg part from moving in the axial direction with respect to the base frame. Even when a reaction force (force toward the panel surface) is generated during the surface drawing operation, the distance between the panel surface and the sheet metal drawing tool can be kept constant. As such a lock mechanism, a screw or a bolt that meshes with a groove provided around the leg portion can be used.

  And in the said drawing tool for sheet metal, the structure for pulling out the panel surface can be carried out without any particular restriction.For example, even if the member joined to the panel surface is manually pulled out, the compressed air is introduced into the piston, It is also possible to employ a member that pulls out a member joined to the panel surface using force. That is, for the configuration other than the above-described leg portion, the structure or configuration employed in a sheet metal drawing tool (puller) that has been known in the past can be used.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is an overall perspective view of a leg module 10 for a sheet metal drawer according to the present embodiment, FIG. 2 is a plan view of the leg module 10 for a sheet metal drawer, and FIG. 4 to 7 are partial perspective views for explaining the usage state of the sheet metal drawing tool, and FIG. 8 is a drawing operation of the sheet metal by the sheet metal drawing tool using the leg module 10. FIG. 9 is a schematic diagram showing a drawing point PP.

  First, based on FIGS. 1 to 3, the sheet metal drawer tool leg module 10 according to the present embodiment will be described in detail. The leg module 10 is a rectilinear seating member formed in contact with the sheet metal surface. 20 are arranged in parallel, and two connecting members 30 are provided in a direction intersecting with the abutment seat member 20. And each connection member 30 is rotatably attached to the fixing member 40 which comprises the attachment part 45 which performs a connection with a sheet metal drawer | drawing-out tool.

  In the present embodiment, the abutment member 20 is formed in a rod shape having a length of about 30 to 50 cm, and is arranged in parallel at an interval of about 8 to 20 cm. Although the size of the dent that can be repaired is increased in proportion to the length of the abutment member 20, on the other hand, it becomes difficult to handle at the time of work, so that it is desirable to be within the above range. Further, the arrangement interval of the abutting seat members 20 is formed so as to be freely adjustable as will be described later. As a result, it is possible to arrange them at intervals exceeding 20 cm. However, considering the ease of handling during the drawing operation, it is desirable to be within the above range.

  Further, an elastic member 21 made of rubber or other resin is attached to the lower surface of the abutting seat member 20 (that is, the surface in contact with the sheet metal surface 50). The elastic member 21 functions as a cushioning material when in contact with the sheet metal surface 50, thereby avoiding a situation in which the sheet metal surface 50 is damaged. In particular, in the leg module 10 for the sheet metal drawer according to the present embodiment, the contact seat is formed long, and the contact seat is formed so as to correspond to the sheet metal surface 50 that is not recessed. It is important to take care not to damage any unpainted areas.

  And the contact member arranged in parallel is connected by the connecting member 30. In the present embodiment, the connecting member 30 is formed in a substantially “A” shape, and is provided at two locations in the length direction of the abutment member 20. Moreover, the horizontal part bent toward the outer side is formed under each connection member 30, and each horizontal part is axially attached with respect to the abutment member arrange | positioned in parallel. In particular, when the horizontal portion of the connecting member 30 and the abutting seat member 20 are axially attached, the connecting member 30 and the abutting seat member 20 are adjusted so that they can rotate relative to each other. As a result, the two abutting seat members 20 and the two connecting members 30 exhibit a four-bar linkage mechanism so that the two abutting member members 20 can approach each other due to the inclination of the two connecting members 30. . In addition, in FIG. 3 which shows this, (A) has shown the state from which the distance between contact seat members is the largest, (B) is the distance between contact seat members from the state of (A). (The same applies to FIGS. 14 and 15 described later).

  Further, the connecting member 30 is rotatably attached to the fixing member 40, thereby realizing an inclined arrangement of the two connecting members 30 with respect to the abutting seat member 20. The fixing member 40 is formed with an attachment portion 45 formed in a shaft shape extending upward, and the leg portion module 10 can be attached to the sheet metal drawer by the attachment portion 45. ing.

  Here, the mounting portion 45 has the drawer shaft P1 in the sheet metal drawer in the center between the abutting seat members 20, that is, in the middle of the arrangement direction of the abutting seat members 20 arranged in parallel. It is desirable to form at a position where the pull-out shaft P1 of the tool is present. This is because the distances from the drawer shaft P1 to the respective seat members 20 are the same. As a result, even if the abutting seat members 20 are brought close to each other, the drawer shaft P1 is always present in the center, and therefore the interval between the seating members 20 can be adjusted without worrying about the position of the drawer shaft P1. it can. In this regard, if the drawer shaft P1 is unevenly distributed near either one of the seat members 20, the drawer shaft P1 is one of the seat members 20 in a state where the seat members 20 are close to each other. Will interfere. Therefore, defining the installation position of the mounting portion 45 is important in actual use.

  Further, the fixing member 40 includes a drawer shaft guide portion 42 that guides at least the drawer shaft P <b> 1 in the sheet metal drawer between the abutting seat members 20. In the present embodiment, the shaft guide portion 42 is embodied as an opening formed in the attachment portion 45 as shown in FIG. The opening is formed in the washer member 50 provided with the attachment portion 45, and the washer member 50 is installed to be rotatable with respect to the fixing member 40. Thus, even if the sheet metal drawing tool is attached to the attachment portion 45, the washer member provided with the attachment portion is rotatable with respect to the fixing member 40. 40 is rotatable with respect to 40.

  The sheet metal drawer tool leg module 10 formed as described above is attached to the various sheet metal drawer tools P as legs as shown by chain lines in FIG. In the embodiment shown in FIG. 4, a hole (not shown) for inserting and fastening the shaft-shaped mounting portion 45 in the leg module 10 is formed in the sheet metal drawing tool P, and the hole The upper and lower sides of the mounting portion 45 are fastened with nuts or the like after allowing the mounting portions 45 to pass. In addition, for example, as shown in FIG. 1, when the mounting portion 45 has an uneven surface, it can be fixed by supporting the unevenness of the mounting portion 45 with a bolt or the like.

  As shown in FIG. 4B, a drawer module M in which a plurality of hooks F are arranged in parallel at regular intervals is provided at the tip of the sheet metal drawer P attached to the sheet metal drawer leg module 10. It is done. Since this drawer module is for pulling out a washer or the like that has been vegetated on the concave sheet metal surface, the washer or the like (not shown) that is pulled out by the module M is vegetated in a substantially straight line in the recess of the panel. become. That is, when the sheet metal surface recessed by the drawer module is pulled out, it is necessary to arrange the drawer module along the extending direction of the recess of the sheet metal surface (vegetation direction of the washer or the like).

  Here, as a method of adjusting the orientation of the drawer module M, it can be considered that the drawer module M is attached so as to be rotatable around the axis of the drawer axis P1. However, even if the drawer module M is rotatably attached in this way, depending on the shape of the recess, depending on the orientation of the seating member 20, the orientation of the sheet metal drawer tool leg module 10 is always constant. The orientation of the sheet metal drawer must be adjusted. Therefore, in the sheet metal drawer tool leg module 10 according to the present embodiment, the washer member 50 is used as described above, and the sheet metal drawer tool P can be rotated with respect to the fixing member 40 (that is, the abutting seat member 20). Thus, the fixing member 40 (that is, the seat member 20) and the drawer module M are formed so as to be freely rotatable with respect to the sheet metal drawer P.

  Next, the operability of the sheet metal drawer tool leg module 10 shown in this embodiment will be described with reference to FIGS.

  FIG. 5 is a view showing that the fixing member 40 (that is, the abutting seat member 20) is rotatable with respect to the sheet metal drawing tool P. FIG. That is, as shown in FIG. 5, when pulling out the linearly recessed dent L, particularly when pulling out the end portion LE of the dent L, it is applied so as to be orthogonal to the extending direction of the dent. It is desirable to arrange the seat member 20. This is to prevent the occurrence of distortion when the sheet metal surface is pulled out in the extending direction of the dent in the drawing process when the dent generated in a straight line is drawn out. However, as shown in FIG. 5A, if the sheet metal drawer P is fixed to the fixing member 40 (that is, the seat member 20), the sheet metal is combined with the direction of the seat member 20. The drawing tool P must be tilted, resulting in an unnatural posture on the operator. Therefore, as shown in FIG. 5B, the sheet metal drawing tool P is provided rotatably with respect to the fixing member 40 (that is, the seat member 20), and the gripping portion PG of the sheet metal drawing tool P is easily operated. It can be directed in the direction (vertical direction in this drawing).

  When repairing a dent generated in the vehicle body panel, it is difficult to incline the vehicle body itself, and a large amount of work is required to remove a part of the vehicle body panel in which the dent is generated. On the other hand, when pulling out the dent generated on the sheet metal surface, it may be necessary to perform a drawing operation with a sheet metal drawing tool at a plurality of locations. In such a case, changing the posture of the worker in accordance with the direction of the dent (stretching direction) results in an increase in the work load, which leads to a reduction in work efficiency. Therefore, in the leg module for the sheet metal drawer according to the present invention, the work efficiency is improved by devising the worker so that the worker can maintain a posture that is easy to work without forcing an unnatural posture. Can be done.

  FIG. 6 is a drawing showing a function for adjusting the distance between the seat members 20 in the leg module 10 for sheet metal drawer shown in the present embodiment. As shown in FIG. 6, when repairing a dent extending linearly on the sheet metal surface, the seat member 20 may be arranged along the direction of the dent. For example, it is a case where a washer or the like vegetated in the length direction of the dent is pulled up at a time. In this way, when the abutting seat member 20 is arranged along the length direction of the dent, as shown in FIG. The distance W1 to the seat member 20 is naturally increased. If the dent is pulled out in such a state, there is a risk that a distort due to the dent will occur within the range up to each abutment member 20, and in the case where a distortion occurs, a separate repair for the distortion is required. Work becomes necessary. Therefore, as shown in FIG. 6 (B), the distance between the seat members 20 is narrowed so that the distance W2 from the recess to each seat member 20 can be reduced, and this occurs with the withdrawal of the recessed sheet metal surface. The distortion of the sheet metal surface is limited to a narrower range.

  When the sheet metal drawer tool leg module 10 according to the present embodiment having the above-described effects is used and the sheet metal surface 50 is pulled out by using the sheet metal drawer tool, first, The distance between the seat members 20 is adjusted according to the size and shape of the recess. When adjusting the distance between the seat members 20, as shown in FIG. 4 and FIG. 6B, the connecting member 30 pivotally attached to the fixing member 40 is attached to its mounting shaft. The distance between the abutment seat members 20 can be narrowed by turning around. The distance between the abutting seat members 20 can be freely set according to the degree of inclination of the connecting member 30 with respect to the inclined member. On the other hand, in order to maximize the distance between the abutment members 20, the connecting member 30 may be set to be orthogonal to the fixing member 40. Further, in order to maintain the inclination of the inclined connecting member 30, the lever-like connecting fixture 41 provided at one of the four connecting portions of the seat member 20 and the connecting member 30 is operated. And it can carry out by preventing rotation of the connection part in which the said connection fixture 41 is provided.

  After that, the seat member 20 is pressed against the recessed sheet metal surface 50, and the tip of the drawer shaft P1 of the sheet metal drawing tool is welded to the recessed sheet metal surface 50, or is drawn out to a washer or the like vegetated on the recessed sheet metal surface 50. The recessed sheet metal surface 50 can be pulled up by hooking the module M and pulling out the drawer shaft P1. At this time, the handle portion PG of the sheet metal drawing tool P is adjusted so that the operator can easily work.

  When pulling out the sheet metal surface, if the recessed sheet metal surface 50 is pulled out from its original height, it becomes necessary to strike the protruding portion with a hammer or the like. Therefore, in the leg module 10 for the sheet metal drawer according to the present embodiment, the abutting seat member 20 is formed long and can be pressed so as to cover the sheet metal surface 50 that is not recessed.

  For example, as shown in FIG. 7A, when the leg module 10 is installed so that the dent member 20 vertically cuts (or crosses) the dent generated in the vehicle body panel 50, The bottom surface indicates the height of the original sheet metal surface 50. Therefore, when the sheet metal surface 50 is pulled out, as shown in FIG. 7B, the pulled-out sheet metal surface 50 is pulled out until it comes into contact with the bottom surface of the seat member 20, thereby causing the recessed sheet metal surface 50 to be pulled out excessively. It can be prevented in advance. In particular, if the distance between the drawer shaft P1 and each seat member 20 is set to be narrow, the sheet metal surface 50 can be supported more reliably (on the bottom surface of the seat member 20) in the drawer operation. For this reason, if it forms so that the space | interval of the abutting seat members 20 can be adjusted like the leg part module 10 for sheet metal drawers concerning this Embodiment, it matches with the magnitude | size and shape of the dent which arose on the sheet metal surface 50. Thus, the interval between the abutting seat members 20 can be reduced as much as possible, whereby the work problem such as excessive drawing of the sheet metal surface 50 can be more reliably solved.

  Further, when the recessed sheet metal surface 50 is pulled out by using the sheet metal drawer tool leg module 10 according to the present embodiment, the pull-out point is subjected to the most recessed portion or the impact when recessed. Part. By pulling up such points, useless drawing work can be eliminated and the sheet metal surface 50 can be efficiently drawn. For example, a dent generated on the vehicle panel surface as shown in FIG. 8 will be described as an example. As a method for pulling out the dent of the sheet metal surface 50, it has been conventionally proposed to pull out from the outside of the dent. However, this method inevitably increases the number of pull-out points because the pull-out operation is forcibly performed from a shallow dent. On the other hand, when pulling out the dent generated on the sheet metal surface 50, if the pull-out point PP, which is the most concave portion (in many cases, the portion to which external force is applied), is pulled out, the dent around it can be raised naturally. Therefore, the number of withdrawal points can be reduced.

  Here, since the extraction point is also a welding point at which the tip of the extraction shaft P1 is welded, the metal strength of the sheet metal surface 50 is reduced at the extraction point due to heat at the time of welding or generation of rust at the welding point. May be weakened. For this reason, if the drawing point increases, the metal strength of the sheet metal surface 50 may inevitably become weak. Therefore, the reduction of the drawing point is desirable also for maintaining the strength of the sheet metal surface 50.

  In this way, in the leg module for a sheet metal drawer in the present invention, the drawing point can be reduced by forming the abutting seat member 20 long, and using this as an index, the most recessed portion or the recessed portion of the sheet metal surface. This is because it is possible to pull out the part to which the impact is applied, that is, the leg module for the sheet metal drawer according to the present invention not only improves workability but also does not reduce the metal strength of the sheet metal surface. Can also be demonstrated.

  Therefore, if the sheet metal surface 50 is pulled out using the sheet metal drawing tool using the leg module 10 according to the present embodiment, even if it is recessed in a relatively large area, It is possible to prevent the sheet metal surface 50 from being pulled out excessively, and to significantly reduce the number of drawer points, thereby not only facilitating sheet metal drawing work but also reducing metal deterioration of the sheet metal surface 50.

Next, other embodiment which can be implemented with the said leg module 10 for sheet metal drawing tools is described based on FIGS.
FIG. 9 shows a mode in which the interval between the seat members 20 can be adjusted in relation to the sheet metal drawer tool leg module 10 shown in FIGS. That is, the sheet metal drawer tool leg module shown in this embodiment is not provided with a configuration for enabling the sheet metal drawer tool leg module to rotate with respect to the sheet metal drawer tool. It is configured so that it can be adjusted. Such a sheet metal drawer tool leg module can be effectively used, for example, when the sheet metal drawer itself is configured to be able to adjust the position of its handle.

  In the leg module for the sheet metal drawer formed in this way, as is apparent from the plan view of FIG. 10, two connecting members formed in a substantially “A” shape in a side view with respect to the fixing member 140. 130 is pivotally attached to the lower end of each connecting member 130, and a seat member 120 is connected to the lower end of each connecting member 130. Then, as shown in FIG. 11, a sheet metal drawer P having a handle portion PG rotatable is attached to the leg module 110 for sheet metal drawer formed as described above. Since the attachment method of the sheet metal drawing tool is as described above, it is omitted in the scissors.

  FIG. 12 shows a modification of the abutment member 120 in the sheet metal drawer tool leg module 110, which is basically the same as the sheet metal drawer tool leg module 10 described above. However, in the sheet metal drawer tool leg module shown in this embodiment, a lever-like connecting fixture 141 is provided at one of the turning pairs of the connecting member 130 and the seat member 120. Thus, by fixing only one place among a plurality of turning pairs, turning of all turning pairs can be prohibited, and work efficiency can be improved.

  13 and 14 show a mode in which the shape of the seat member 201 is changed. The abutting seat member 20 in the above-described embodiment is formed as a linear rod, but in this embodiment, the abutting seat member 201 or 202 is curved and formed into a two-dimensional shape. Specifically, as shown in FIG. 13, it can be formed as an abutting seat member 201 curved in an arc shape, and can be arranged in combination so as to face each other. Moreover, as shown in FIG. 14, it can also be set as the abutment member 202 which formed the bending part of the direction which cross | intersects with this rod at the front-end | tip and rear end of a linear rod.

  In the case where the seating members 201 and 202 are curved as shown in FIGS. 13 and 14, a region surrounded by the seating member appears in a state where the members are brought close to each other, and a sheet metal existing in this region is formed. Only the surface 50 can be pulled out. That is, the sheet metal surface 50 drawn out by the pull-out shaft P1 is limited to the region from the pull-out point to the seating member, so that the problem of the sheet metal surface 50 outside this region being pulled out during the pulling operation can be solved. it can. Such a shape of the abutment members 201 and 202 is advantageous in that the drawing region can be defined particularly when the region where the dent is generated is narrow. Further, there is an advantage that the distortion of the sheet metal surface caused by the drawing work can be limited to the area surrounded by the abutting seat members 201 and 202.

  Further, FIG. 15 shows an embodiment in which the shape and structure of the connecting member 30 are changed, and the aspect before and after the deformation of the abutment member 20 in the sheet metal drawer tool leg module 10 differs accordingly. Yes.

  That is, the connecting member 301 in the leg module 10 for sheet metal drawer shown in FIG. 15 is formed so as to be expandable / contractable in the axial direction, which fixes the slide portions 32 connected to the respective seat members 20. It is formed in a sheath part 31 installed on the lower surface of the member 40 so as to be able to advance and retract. That is, the distance between the abutting seat members 20 can be freely adjusted by pulling out or inserting each slide portion 32 from the sheath portion 31 (FIG. 15B). It should be noted that it is desirable to provide a screw or other fixing means for fixing the drawn slide part to the sheath part.

  Further, if the joining position of each slide portion with the seat member 20 is swingable and the sheath member is swingably attached to the lower surface of the fixing member 40, each seat member 20 can be further freely arranged. The leg module 10 for a sheet metal drawer that can be realized is realized.

  In the sheet metal drawer tool leg module 10 having the connecting member 301 as shown in FIG. 15, when changing the interval between the abutting seat members 20, the abutting seat members 20 face each other. It can install in the state which aligned the horizontal position of the front-end | tip and rear end of 20.

  The sheet metal drawer that can be used in combination with the leg module 10 shown in the above embodiment can be used without particular limitation as long as it is a hand-held sheet metal drawer currently provided. However, it is necessary to provide a connection structure for connecting the leg module 10 for sheet metal drawer according to the present invention. And what is necessary is just to fix the fixing means in this leg module 10 for sheet metal drawer tools, and to be able to extend | stretch the drawer shaft P1 between abutting seat members.

  Further, the pull-out shaft P1 that exists between the abutment members 20 and pulls out the recessed sheet metal surface 50 has a tip that is welded directly to the sheet metal surface 50, a washer or the like that is fused to the sheet metal surface 50, or the like. It is also possible to pull this out. Further, when the sheet metal surface 50 is pulled out, either one pulling out one pulling point or pulling out a plurality of pulling points may be performed by one pulling operation.

  In the sheet metal drawer tool leg module shown in the above embodiment, the pair of seating members 520 formed short can be attached by using the seating member in a detachable manner. A method for attaching the abutting seat member to the connecting member is not particularly shown, but a known means such as a screw, a hook or the like can be used.

  If this embodiment is shown concretely, as shown in FIG. 16, the leg part for sheet-metal drawers which each attached the short base member 520 to each connection member 30 formed in "A" shape will be shown. It is a module. In particular, in this embodiment, the connecting members provided so as to be rotatable with respect to the fixing member 40 are formed in positions and sizes that do not interfere with each other, so that the connecting members are rotated. Accordingly, as shown in FIG. 17, the postures of the pair of seating members can be arranged along the length direction of the fixing member and linearly. In addition, one of the seating members can be in a direction (posture) that intersects the fixing member, and the other seating member can be oriented along the fixing member. That is, since each connecting member can rotate independently, it is also possible to make the abutting seat member in various postures.

  Furthermore, as shown in FIG. 17, in a state where the two seat members are arranged in a straight line, if a gap is secured between the two seat members, the drawer shaft P1 in the sheet metal drawing tool should be present between the seat members. Can do. Therefore, by forming in this way, it is possible to adjust the arrangement posture of the abutment members in various ways, arrange the abutment members in the most suitable postures in the dents generated in various shapes and parts, and pull out work Will be able to do.

In particular, when such a short bearing member is used, the rigidity thereof is increased, and unintended bending of the bearing member due to a load during the drawing operation can be reliably prevented. For example, even when this abutting member is arranged in a direction intersecting with the ridge-shaped bent portion in the vehicle body panel, that is, even when the abutting member is locally in contact with the sheet metal surface, a heavy load is applied. It is possible to prevent deformation due to various loads.
Therefore, it becomes possible to select and use the optimum length of the seat member according to the state of the place where the drawing work is performed and the place where the seat member is arranged.
