(Points of interest)
Curved wood processing is characterized by lower production costs, lighter and more robust compared to ordinary curving, which cuts and cuts wood (direct material), and has a seamless and beautiful appearance. Since ancient times, mechanical bentwood and inner molds that can be processed quickly and powerfully using various bentwood machines such as rotary bentwood machines, push-in bentwood machines, lever-type bentwood machines, press-type bentwood machines, etc. Clamp one end of the material to be bent and the band iron to one end of the wire, then clamp the other end of the material to be bent and the band iron and then gradually bend along the inner mold to Various processing methods have been adopted, such as hand-made bent wood that follows the work procedure of clamping the inner mold and bending the whole.

    In such bent wood processing, it is necessary to prepare a concave and convex mold for each curved shape to be manufactured, and in the case of mass production of products with a fixed shape, in order to increase the production efficiency and economy. Although effective, it is necessary to produce and prepare different rugged molds for each product each time when carrying out high-mix low-volume production, which can be said to be the current mainstream, and the product price increases due to an increase in production costs and setup man-hours. In the case of single-item manufacturing or extremely small-volume production, there is a disadvantage that it is completely economical and results in a great economic burden on the orderer or producer. Was.

(Conventional technology)
As a breakthrough, for example, as proposed in Japanese Patent Application Laid-Open No. 7-186109, "curved plate" invention, each has a plate insertion hole at one end, and a cradle is provided at the other end. A long groove hole is formed along the longitudinal direction between the cradle and the abutment plate insertion hole, and a plurality of upper and lower mounting bases with screw rods inserted from the cradle are formed in the long groove hole and a plurality of mounting bases are provided. The abutment plate insertion hole outer wall and the adjacent abutment plate insertion hole outer wall are pivotally connected to each other in the lateral direction, and both ends of the abutment plate are fitted and attached to the upper and lower abutment plate insertion holes, respectively, Inserting both ends of the pressing plate into the bottom of the long groove hole to form a fastening portion between the contact plate and the pressing plate, and expanding the mounting plate on either the upper or lower side to the left or right mounting The base is expanded synchronously, and the member to be processed attached to the attachment portion corresponds to the expansion of the attachment base. By making it possible to form a curve, the abutment plate and the pressing plate for attaching the plywood, etc., which are the members to be processed, are detachably formed, and the structure is extremely simple, so that it can be easily disassembled and made compact and transported and stored. The work can be simplified, the cost can be reduced, and the plates of any width can be bent only by changing the lengths of the contact plate and the pressing plate.

    In addition, as disclosed in Japanese Utility Model Publication No. 58-48088, “curved plate device”, a fixed plate is fixed to each end of a plurality of mounting bases, and this plate and an adjacent plate are hinged to each other. Then, the corresponding plate is formed in an arbitrary arc shape by expanding the mounting base in a lateral direction, and pressing the counter plate so as to move back and forth along a guide provided on the mounting base A plate is attached to the tip of a threaded rod inserted into a support, and a sandwiching part is freely adjustable between the corresponding plate and the pressing plate. A hinge is attached between this plate and the adjacent plate to create an arc. In some cases, the plywood can be bent into an arbitrary arc shape by changing the degree of.

However, both the former and the latter “curved plate” must be designed exclusively for the compression of bent wood by the entire device including the complicated vise part of the structure, and the curve of the molded bent wood Each vise part arranged in line with the shape must be arranged closely so as to narrow the gap as much as possible in order to obtain a precise curve molding, and as a result, the curvature radius to be molded increases, Not only does it require more vise parts to become larger and more complicated, and the cost of manufacturing the bent plate itself increases, but the weight of the equipment increases, increasing the labor burden of transportation and installation work, The number of man-hours for the entire device increases, which greatly increases the man-hours for tightening and loosening the vise part during the bentwood manufacturing process, which reduces the economic efficiency of curved plate processing. It was.

(Awareness of problems)
As described above, all of the previously proposed “curved plate devices” must be a combination of special parts that are specially designed and manufactured to produce curved plate devices. Since the most complex vise parts with the most structure must be arranged so as to be closely adjacent to each other along the curve of the curved wood, the more the curved plate processing with a large curvature radius, the more As a result of the need for a vise, the price of the bent plate itself increases and the total weight also increases significantly. As a result, the number of setup steps such as transportation, installation, withdrawal and storage during the bentwood production process is reduced. Not only the increase, but also during the molding process, tightening and loosening operations are required for all the vise parts arranged closely, increasing the number of man-hours for production and increasing the labor burden on the producer. Product at the same time It was supposed to leave the big problem that led to the rise of case.

(Object of invention)
Therefore, the present invention reduces the manufacturing cost of the vise part that requires a plurality of units as much as possible, reduces the weight of the device itself, and improves the handling workability, and further increases the radius of curvature of bent wood processing. By reducing the required number of vise parts associated with, as much as possible, the number of man-hours during setup and curved wood production can be greatly reduced compared to the conventional “curved plate device”. Judging whether it is possible to develop a new bent wood processing technology that can reduce labor and at the same time reduce the cost, we started its development and research very quickly, and many trials and errors over many years. As a result of repeating trial manufacture and experiment, this time, we finally succeeded in realizing a bent tool part with a new structure and a bent tool with a new structure using it.

What can be combined in a serpentine shape Become the Kyokuki parts tool.

(Related invention)
In relation to the above-described parts for bent wood tools, this invention also includes bent wood tools using the same.
That is, the target commercially available so that a plurality of temporary fixing holes for fixing on the work platform are L-shaped in cross section from the tip of the thick strip-shaped base plate portion that is vertically penetrated. The same thick strip-shaped support plate that is set longer than the fixed arm length of the clamp is raised vertically and integrated into the mounting bracket body, and the width dimension near the base end of the mounting bracket body support plate In the center, a clamp mounting hole through which the rail part of the target commercial clamp can be inserted penetrates and is drilled in the thickness direction, and in the vicinity of the clamp mounting hole, from the mounting bracket main body base plate part Is also arranged parallel to the top, can be temporarily fixed horizontally via a height adjustment mechanism, is combined with a mounting table for mounting a material for bending work, and each of the edges in the width direction of the support plate portion. Connection made by drilling a vertical connection hole at a predetermined location , And a clamp holding bracket with an overall F-shaped side cross-sectional shape. Mount the rail part of the target commercial clamp in the clamp mounting hole, and support the tip pressing surface of the fixed arm. A width dimension corresponding to the support plate part at the front end of the tightening handle which is brought into contact with the back surface of the plate part and the end of the movable arm is screwed to the alligator, and a vertical dimension which can move forward and backward without interfering with the mounting table. A clamp plate having a universal joint mechanism that can be tilted and tightened is provided, while the clamp holding bracket has a thick strip-like shape like the mounting bracket body support plate portion. Corresponding connecting rings with vertical connecting holes drilled at appropriate positions that do not interfere with the connecting ring of the clamp holding bracket when positioned adjacent to the mounting body support plate for the previous clamp holding bracket at the width direction edge. As a single unit It is a connecting bracket that has a wide I-shaped front, and the connecting rods of both brackets correspond to each other and the connecting holes of the corresponding connecting rings are concentrically arranged so that the connecting rod can be inserted and removed freely. This is a bent wood tool that uses the above-mentioned components that form the basis of the present invention, and is formed as a hinge-like connection, and a plurality of them can be combined in a curved shape or a meandering shape in a planar arrangement.

    As described above, according to the bent wood tool part of the present invention, the target commercially available clamp can be incorporated in a predetermined posture into the clamp holding bracket manufactured by the exclusive design so that the entire side cross-sectional shape is a fallen F shape. Replaced the clamping mechanism itself, which has been a factor in raising the production cost of the mold curved plate device, with a ready-made target commercial clamp that has been reduced in price, reduced in weight and stabilized in quality in the market, As a whole, the bent wood tools can be manufactured and sold at low cost, and in the case of aging or damage, maintenance of each part and replacement with a new part can be performed easily and reliably for each required part. In addition to the convenience of use as a bent wood tool, it is possible to provide an excellent effect that a bent wood tool that is particularly advantageous in terms of its economy can be provided.

    In addition, the mounting bracket body support plate part of the clamp holding bracket manufactured so that the overall side cross-sectional shape is an inverted F-shape is connected to the mounting bracket adjacent to the wide I type on the entire front side. The connecting rods of the two metal fittings correspond to each other, and the connecting rods are detachably inserted into the corresponding connecting rings to form a hinge-like connecting structure, and a plurality of them can be combined in a curved shape or a meandering shape in a planar arrangement. Since the connecting bracket is interposed between each clamp holding bracket in which the target commercially available clamp is incorporated, the vise part is in close contact with each other when manufacturing bent trees with the same radius of curvature. Compared to the conventional curved plate unit connected to, the weight can be reduced and the cost can be reduced, the setup of bentwood production and the efficiency of manufacturing work are promoted, and the labor burden on workers is greatly increased. It is possible to reduce It is possible to install and use the target commercial clamp inside the curved circle of curvature, which has never been envisaged, and it is possible to manufacture not only single arc shapes but also complicated curved meandering curved trees The effect of becoming is also obtained.

    In addition, the base plate portion is formed in a thick strip shape, and the bent wood tool itself incorporating the target commercially available clamp can be stably placed on any place on the work platform, and a plurality of Temporary fastening holes are drilled up and down and fixed securely using various fastening parts such as nails, tapping screws, bolts and nuts, and a plurality of bent wood tools are arranged in a planar arrangement in the desired curved shape or meandering It has the advantage that it can be temporarily fixed to the shape.

    The mounting bracket main body is vertically integrated from the tip of the base plate portion with a thick strip-shaped support plate portion set longer than the fixed arm length of the target commercial clamp so that it has an L-shaped side section. A rail that is opposite to the fixed arm of the target commercial clamp from which the movable arm is removed is drilled in the vicinity of the base end of the support plate portion so that the rail portion of the target commercial clamp can be inserted. Attach the end of the support plate part to the clamp mounting hole, and operate the rail part to be pulled out on the base plate part so that the fixed arm tip pressing surface of the target commercial clamp contacts the back of the support plate part. In combination, the surface of the support plate part forms a wall surface that substantially presses the bending material against the clamping handle of the movable arm that is mounted so as to be movable forward and backward from the end of the target commercial clamp rail part. , Can be incorporated with an organic ties the target commercial clamping as part of Kyokuki tool, the effect is obtained that yet can be easily separated.

    And this support plate part is mounted on a mounting table, and a protective plate made of a highly elastic material is mounted on the surface of the crease facing the bending material to be processed, and the bent wood processing step Can be easily and reliably prevented from damaging the bending material that is pressed in the case. Furthermore, when the protective plate of the support plate portion is arranged outside the curved curvature circle, a flat cross-sectional shape is used. Concave type, curved wood processing curvature circle inside arrangement according to the arrangement condition so that the flat cross-sectional shape is a convex arc shape set to the curvature equal to or smaller than the curved wood processing curvature In addition, it is possible to more reliably prevent the bending material from being damaged, and the conventional band iron or concave-convex type. Disperse the pressure on the pressure surface more evenly than those using Is to prevent damage to the target bending timber, more precisely tune wood finishing is what can be expected.

    In addition, this mounting table is combined in such a manner that it can be temporarily fixed in a horizontal arrangement in a parallel arrangement above the mounting bracket main body base plate near the clamp mounting hole in the mounting bracket main body support plate. Yes, the bottom part of the bending material placed in a mounting manner between the surface of the support plate part and the fastening handle of the target commercial clamp movable arm facing it is stably supported at the desired height position. Therefore, it is possible to realize more accurate bent wood processing, and it is possible to prevent the bending material bottom portion from interfering with the rail portion of the target commercial clamp that is mounted so that the underside of the mounting table is arranged in a bending manner. The effect of protecting the processing material bottom from damage can be obtained.

    In addition, if the target commercial clamp fixing arm of the support plate part and the back surface against which the tip pressing surface comes into contact are incorporated with a clamp rollover prevention mechanism that allows the appropriate position of the fixing arm to be detachably and temporarily fixed, During the preparatory work until the work or bending material is clamped, the target commercial clamp built into the clamp holder will inadvertently roll over, causing the tip arm clamp surface to move from the proper contact position on the back of the support plate. It is possible to prevent the inconvenience of detachment and greatly increase the work efficiency of bent wood processing, and the fixed arm tip pressing surface that is detachably temporarily fixed to the back of the support plate part is simple, It becomes possible to quickly remove and realize quick disassembly and assembly, and exhibits features that make disassembling and transporting, storing, assembling and installing work of bent wood tools much more efficient.

    The height adjustment mechanism of the mounting table allows you to freely adjust and temporarily fix the mounting height position of the mounting table to the surface of the mounting bracket body support plate part within a specified range. It is possible to adapt flexibly to processing materials, and up to now it is necessary to prepare multiple types of curved plate devices with different pressing surface dimensions. It is possible to cope with it, and it is possible to reduce the economic burden as much as possible, and to achieve an excellent effect of greatly reducing the number of man-hours required for exchanging the bent plate.

    And while this height adjustment mechanism shall pass through two long holes parallel to the vertical shape in a symmetrical manner in the width direction of the support plate portion in the plate thickness direction, at the base end edge of the mounting table, It is assumed that a horizontal screw hole is drilled in each of the locations corresponding to the long holes, and the back of the support plate part is known, and the tip of each screw part of the two positioning bolts loosely attached to each long hole corresponds to It is assumed that it can be tightened loosely by screwing into each horizontal screw hole of the mounting table described above, so that it can be fixed as a certain tilt posture in addition to the vertical movement of the mounting table, etc. Compared with the conventional type, it also has the feature that it can realize curved tree processing of a more complicated shape.

    Clamp holding bracket mounting bracket body support plate part A connecting ring is integrally formed at each of the both ends in the width direction of the clamp, and clamped when the clamp holding bracket of the coupling bracket is placed adjacent to the mounting bracket body support plate part. It is assumed that corresponding connection rings are integrally formed at appropriate positions that do not interfere with the connection rings of the holding metal fittings, and the connection rods corresponding to both metal fittings are connected to each other and the connection rods are detachably inserted into the hinges to connect them. It is possible to combine a plurality of bent wood tools in a curved or meandering manner in a flat arrangement on the work platform by one-touch operation of simply connecting and disconnecting each connecting rod. , And since it can be disassembled, its working efficiency is greatly improved.

    Even when three or more connecting metal fittings are arranged adjacent to each other in a plane, they are connected to each other in a hinge-like manner around the vertical axis while maintaining the same spacing between the clamp holding metal fittings. Therefore, it is possible to combine a plurality of bent wood tool parts correctly in a planar arrangement with each other in a curved shape or a meandering shape, and eliminates the adjoining arrangement of vise parts like a conventional curved plate device. When performing the same bent wood processing, the number of clamp holding brackets (corresponding to the vise part of the conventional product) can be halved compared to the conventional product. It is placed on the work platform without the need to measure the arrangement interval of each one, and it is automatically arranged at equal intervals just by the procedure of arranging multiple clamp holding brackets along the curvature circle of curved wood processing Because it will be possible In addition, even when the material for bending is pressed, the adjacent spacing between each clamp holding bracket is accurately and sufficiently restricted, so that highly accurate bent wood processing is possible. We can enjoy effect that we can realize

    On the other hand, according to the bent wood tool of the present invention, in addition to being able to demonstrate the effects of the bent wood tool parts as described above, the bent metal tool parts are sold in combination with the target commercial clamp in advance. Then, the purchaser can save the trouble of separately searching for and purchasing a target commercially available clamp that can be combined with the above-described bent wood tool part of the present invention, and the combined state and quality check of all parts. Can be completed at the production plant, a combination of more stable quality can be ensured, and a safe and superior quality curved wood tool can be reliably provided to consumers. Is.

    In addition, the rail part of the target commercial clamp is attached to the clamp mounting hole drilled in the mounting bracket body support plate part, the tip pressing surface of the fixed arm is brought into contact with the back surface of the support plate part, and the tip of the movable arm A universal joint mechanism that can be tilted and tightened at the front end of the tightening handle that is screwed on the side, with a width corresponding to the support plate and a vertical dimension that can move forward and backward without interfering with the mounting table. Can be started efficiently without any trouble from the beginning of introduction, and the pressing plate having a universal joint mechanism is applied to the pressing surface of the bending material. The uniform bonding effectively avoids intensive pressurization to a part, and the occurrence of processing defects is greatly reduced.

    And with the pressure plate attached to the tip of the tightening handle of the target commercial clamp, with a protective plate made of a highly elastic material on the surface, it can more reliably prevent damage to the bending material, Furthermore, when the protective plate is arranged outside the curved curvature circle, the flat cross section is a concave shape, and when the protective plate is arranged inside the curved curvature radius, the flat cross section is equivalent to the curved curvature. Or a convex arc shape set to a curvature smaller than that and a shape corresponding to the arrangement, respectively, so that it can be used properly and attached to the surface of the corresponding pressing plate detachably. In the case of processing, the scratching phenomenon of the bending material after finishing the processing process can be avoided, and the pressure surface pressure is more evenly distributed than those using conventional band irons and rugged molds. Can be finished into a precise and precise curved tree In which a large effect can be obtained.

In implementing the present invention having the configuration as described above, the best or desirable mode will be described.
The bent wood tool part performs the function of enabling the bent wood tool which is the final object of the present invention by incorporating the target commercially available clamp at a predetermined position in the predetermined position. It should be possible to realize ideal bent wood processing by combining the above, and it is possible to easily detachably mount the target commercial clamp without using assembly tools, etc., and withstand bending wood processing It should have sufficient strength, and is preferably set to a shape, size, and weight that can be easily carried by a single worker. More specifically, it will be described in the embodiments described later. In this way, the support plate is raised from the base plate tip so that it has an L-shaped side section, and is integrated with the mounting bracket body, and clamped near the base end of the support plate A clamp holding metal fitting in which a mounting base that is perforated and combined with a mounting table that can be horizontally fixed in a parallel arrangement above the base plate portion is combined so that the entire side cross-sectional shape is an inverted F-shape, The whole front shape is formed to be a wide I type, and includes a connecting metal fitting that can be detachably connected to both ends of the support plate in the width direction.

    In the bent wood tool of the present invention, basically, the rail portion of the target commercial clamp is mounted in the clamp mounting hole of the bent wood tool part, and the tip pressing surface of the target commercial clamp fixing arm is the back of the support plate portion. Is set to the width of the support handle and the vertical dimension that allows it to move forward and backward without interfering with the mounting table. It is necessary to provide a pressing plate having a universal joint mechanism that can be tilted.

    The clamp holding metal fitting is obtained by mounting a target commercially available clamp at a predetermined location and detachably connecting with a connecting metal fitting in a hinge-like manner in a planar arrangement in a curved shape or a meandering shape. A mounting bracket body having an L-shaped side cross section that has the function of forming a bent wood tool and has sufficient strength to perform bent wood processing, and the entire side cross-sectional shape is F-shaped on the support plate. It must be composed of a mounting base that is attached with sufficient strength so that it can be a mold, and at least it can be easily handled such as transport and storage in a single state with the target commercial clamp or coupling bracket removed. It can be said that it is desirable to keep the shape, size, and weight so that one worker can easily carry it.

    The mounting bracket body allows the clamp holding bracket to be stably installed on the work platform and temporarily fixed so as to have a desired arrangement, and the target commercially available clamp can be incorporated at a predetermined location on the back. The material to be bent can be clamped between the support plate part with the fixed arm of the target commercial clamp and the clamp handle end of the target commercial clamp movable arm, and the desired height of the support plate part can be clamped. This function serves to make it possible to temporarily fix the mounting table that can support the bending material in the horizontal position in the horizontal position, and to enable stable temporary fixing on the work platform. A thick strip-shaped base plate part is formed, and the support plate part formed in a thick strip shape enough to withstand bent wood processing is vertically integrated so that it has an L-shaped side section from the tip. The base plate and support It is desirable that the joints with the parts should be formed separately and integrated by various joint structures such as welding, brazing, press-fitting, bolts / nuts, rivets, etc. In addition to being integrally molded by casting or pressing, it is also possible to be one cut out from a single block material.

    The base plate enables the mounting of the clamp holding metal fitting body to be stably placed at an appropriate place on the work platform and to perform bent wood processing at a desired location on the work platform. Functions to enable temporary fixing with sufficient strength so that the support plate, mounting table, connecting bracket and target commercial clamp can be supported directly or indirectly as they can withstand the bending of wood It should be formed substantially in the shape of a thick strip, and the left and right maximum width dimension should be set so as not to exceed the left and right width dimension of the support plate portion erected on the tip side. It is desirable to set the length dimension as short as possible within a range that does not lose the stability of mounting on the work platform.For this reason, the wall thickness should be set large or a weight should be set to ensure a weight balance that will not fall over. Stable by wearing etc. For example, the curvature of the bent wood processing is sufficient as long as it can fit within the wall-shaped strip shape and can stably support the support plate and other parts. A support leg is provided that expands or stretches when placed outside the circle to enhance placement stability, and folds or shrinks when placed inside the same circle of curvature to avoid interference between adjacent ones. As shown in the examples to be described later, a plurality of temporary fixing holes for fixing on the industrial platform should be formed in a vertically penetrating manner at appropriate positions. .

    The support plate allows the target commercial clamp to be mounted at a specified location on the mounting bracket body, and its surface is the target instead of the tip pressing surface of the target commercial clamp fixing arm placed in contact with the back. A clamped handle of a commercially available clamp movable arm can be clamped by inserting the bent wood workpiece between the arms and placing the bending work material at a desired height position where this surface becomes a trap. The mounting base can be built in, and the connecting bracket can be attached to the both ends of the width direction in a hinge-like manner. In addition to drilling a clamp mounting hole that can be inserted through the rail portion of the target commercial clamp in the thickness direction, it is arranged parallel to the upper part of the mounting bracket body base plate in the vicinity immediately above the clamp mounting hole. With horizontal temporary fixing Combining possible mounting tables, and integrally forming a connecting ring for connecting the connecting bracket at each predetermined position of the both ends of the support plate in the width direction, ensuring sufficient strength to withstand bent wood processing, It must have a substantially thick strip shape set longer than the fixed arm length of the target commercial clamp.

    And, it is possible to mount a protective plate made of a highly elastic material on the surface that becomes a trap opposite to the bending material to be processed by mounting on the mounting table, and if necessary As shown in the examples to be described later, the protective plate is a concave section of a flat cross section when it is arranged outside the curved curvature circle, and a flat cross section when it is arranged inside the curved curvature circle. In order to be a convex arc shape with a curvature equal to or smaller than the curved wood processing curvature, it is formed in advance according to the arrangement location and can be used properly. In addition to being able to be detachably mounted on the surface, it is possible to temporarily fix the appropriate position of the fixed arm detachably on the back surface against which the tip pressing surface of the target commercial clamp fixing arm comes into contact. Incorporating a rollover prevention mechanism for clamping It is possible to be.

    The clamp mounting hole guides the rail part of the target commercial clamp from which the movable arm is removed to the base plate part with the back surface near the base end of the base plate passing through the side of the base plate, and the movable arm can be moved forward and backward. At the same time, it has a function that can be combined so that the fixed arm tip pressing surface of the target commercial clamp comes into contact with the back of the support plate, and penetrates in the thickness direction near the base end of the support plate. The rail part of the clamp must be open to a shape and size that allow it to be gently mounted, and as shown in the examples described later, it should be penetrated in the center of the width dimension near the base end of the support plate. Should.

    The connecting ring is adjacent to each end in the width direction of the mounting bracket body support plate of the clamp holding bracket, and does not interfere with the corresponding connecting ring of the connecting bracket that is arranged, and the connecting holes are concentric with each other. It has a function that allows it to be connected in a hinge-like manner by detachable insertion of the connecting rod, has a strength that can withstand curved wood processing, and each of the edges in the width direction of the support plate portion is predetermined. It must be integrally formed at a location, and a vertical connection hole should be drilled at a location near the center where it can be combined in a concentric arrangement with the connection hole of the corresponding connection ring. The connecting hole should preferably have a diameter that allows the connecting rod to be easily inserted and removed.

    The rollover prevention mechanism for the clamp is equipped with a rail part in the mounting body of the clamp holding bracket and the clamp mounting hole drilled near the base end of the support plate, and the tip pressing surface of the fixed arm contacts the back of the support plate. When the target commercial clamp is in contact with the support plate and the clamping plate provided at the tip of the clamping handle where the tip of the movable arm is screwed together, It functions to temporarily fix it in place without inadvertently moving or detaching it from the bent wood tool parts when pressing the material, etc. At least during the pressing operation of the bending material It shall be possible to hold the target commercial clamp to the extent that it does not fall with respect to the clamp holding bracket, and shall consist of a fastener or a band provided at an appropriate position on the back of the support plate, On the back of the plate From each of abutting target commercial clamping tip clamping surface nearest the left and right sides positioned to become point on the back, it is possible to consist of right and left support pins is stretched horizontally at right angles and orientation to the rear.

    When the mounting table is subjected to bent wood processing, the surface of the clamp holding bracket support plate and the pressure provided at the tip of the tightening handle screwed to the target commercial clamp movable arm incorporated in the bent wood tool part. Bending material sandwiched between the surfaces of the clamp plate has a function to enable support at a desired height position, and has sufficient strength to hold the bent wood processed material. The lower edge of the wood must be shaped so that it can be supported horizontally, and the lower edge of the bent wood workpiece can be supported in a slightly inclined posture at an arbitrary angle, and the upper surface is bent. In addition to being able to detachably attach a soft or hard protective component that protects the bottom of the material, as shown in the examples described later, it was temporarily fixed to an appropriate position of the support plate portion via a height adjusting mechanism. It can be said that it is desirable.

When combined in a shape or a meandering shape, the support plate portions of each bent wood tool are prevented from being directly adjacent to each other as in the conventional type, and the distance corresponding to the width dimension of the connecting bracket In addition to the support plate portion, the support plate portion and the support plate portion can be joined to and supported by the pressing surface of the bending material. Similarly, it must be formed into a thick strip having sufficient strength, and the width direction end edge corresponding to one of the both end edges in the width direction of the support plate is arbitrarily selected. Hinged connection structure that can be removed The width direction edge that does not interfere with the connecting ring of the clamp holding bracket when it is placed adjacent to the mounting bracket body support plate of the clamp holding bracket as shown in the embodiments described later. Corresponding connection rings with vertical connection holes drilled at appropriate positions are integrally formed, and the overall front shape is wide I type, and the corresponding connection rings of both metal fittings and the connection holes of the corresponding connection rings are concentric. The connecting rod is detachably inserted as a shape arrangement so that it can be connected to a hinge-like structure.

    In addition, the connecting metal fitting may be formed by mounting a protective plate made of a highly elastic material on the surface of the crease facing the bending material to be processed. If the outer shape of the machining curvature circle is arranged, the flat cross section is a concave shape.If the inner shape of the curved machining curvature circle, the flat section shape is equal to or smaller than the curved machining radius. It would be convenient if it should be formed in advance so that it can be used properly depending on the arrangement location so that it becomes a convex arc shape set to, and it can be detachably attached to the surface of the corresponding fitting Become.

    The corresponding connecting ring of the connecting bracket is a support plate when the connecting bracket is disposed adjacent to any one of the both ends in the width direction of the clamp holding bracket mounting bracket main body support plate portion. It is combined without interfering with the connecting ring of the part, fulfills the function of enabling hinged connection by inserting the connecting rod, has strength to withstand bent wood processing, and both ends in the width direction of the connecting bracket It must be integrally formed at a predetermined location that is an edge and is in an arrangement relationship that does not interfere with the connection ring of the support plate portion, and is combined with the connection hole of the connection ring in the vicinity of its center It should be formed by drilling a connecting hole in the vertical direction where possible, and like the connecting ring, the connecting hole was set to a diameter that allows the connecting rod to be easily inserted and removed. Shall be.

It is desirable to provide a pressing plate having a universal joint mechanism that is set and can be tilted.

    The universal joint mechanism of the pressure plate not only supports the position of the pressure plate facing the surface of the support plate part perpendicular to the surface of the support plate part, but also slightly tilts with respect to the surface of the support plate part. The ball can be supported even in such a posture and can be pressed as it is, and the support angle to the tip of the tightening handle is a ball joint that can be freely changed by external force. It can be said that it is desirable that the pressure to be applied can be automatically dispersed and homogenized during the tightening operation.

    The protective plate prevents damage to the bending material due to the strong contact of hard parts such as the surface of the support plate and the surface of the pressure plate opposite thereto, and also distributes the clamping pressure applied to the bending material, It has the function of achieving homogenization and must be made of a softer material compared to the support plate and pressure plate, for example, natural rubber plate, synthetic rubber plate, foamed resin plate, felt laminate It can be made of a highly elastic material such as a wooden plate or a soft metal plate, or a plastic material, and it should be made of a highly elastic material such as a hard rubber plate in consideration of durability or economy. is there.

In the case of the inner arrangement of the wood processing curvature circle, depending on the arrangement location, the flat cross-sectional shape is a convex arc shape set to a curvature equal to or smaller than the curvature wood processing curvature, respectively. It should be formed in advance so that it can be used properly and should be detachably mounted on the surface of the support plate or the surface of the pressure plate.
The work platform is combined with a plurality of bent wood tool parts or bent wood tools placed on the upper surface in a curved shape or a meandering shape in a planar arrangement, and withstands the bent wood processing in the arrangement relationship. It must be capable of being temporarily fixed with the strength it obtains, and must have sufficient strength and stability.

The material for bending is a processed material that can be a target of bent wood processing using the bent wood tool of the present invention, and is a common material for woodworking natural wood, such as hickory, toriko, enju, shiji, shi, However, broad-leaved trees such as zelkova, maple, cherry blossoms, and walnuts are more suitable for plasticity than coniferous trees. It is also possible to target wood that combines them, and further, bent wood processing is applied to laminated plywood and laminated wood that are laminated and integrated with a large number of thin single plates coated with adhesive Of course, it is possible to do this, and it goes without saying that all of them can be targeted.
