[Industrial applications]

 The present invention relates to a roof rack used for roofs of passenger cars and jeep, for example. Further, for example, the present invention relates to a rack mounting device for a roof rack.

[0002]

[Prior art]

 Traditionally, it has been considered to carry a luggage by placing a rack on the body of an automobile. For example, racks for special purposes such as a rack for skis, a rack for bicycles, and a rack for surfboards are being considered. Also, a rack for luggage for carrying boxes, cases, bags, etc. has been conventionally considered. FIG. 20 and FIG. 21 show an example of a rack for loading such a conventional load. FIG. 20 shows a rack disclosed in Japanese Utility Model Publication 1-23874. In the figure, 20 is a rack, 2 is a rack base frame, 6 is a reinforcing frame, and 4 is a mounting portion for mounting the rack 20 to the vehicle body 10. Further, FIG. 21 shows a rack disclosed in Japanese Utility Model Publication No. 4-13250. In the figure, a rack 20 is composed of a base frame 2, a sub-frame 5, a plurality of plates 3 and a mounting portion 4, and is mounted on a vehicle body 10. As shown in FIGS. 20 and 21, the conventional rack-carrying portion is composed of only a frame, or a frame and a plate arranged in a saw-tooth shape. Alternatively, although not shown in the figure, it is composed of a mesh-like structure such as a wire mesh.

FIG. 22 is a perspective view of the rack shown in Japanese Patent Application No. 4-88716. FIG. 23 is a diagram showing a mounting state when the rack shown in FIG. 22 is mounted on the vehicle body. Reference numeral 10 denotes a vehicle body of a passenger car, a jeep, etc. The vehicle body 10 has a roof 111, and a rain garter 122 protruding from the roof is present. FIG. 24 is a cross-sectional view taken along the line AA of the rack shown in FIG. 22 and a reference diagram showing a usage state. FIG. 25 is a diagram showing a connecting portion between the plate and the base frame.

Next, the structure of this rack will be described with reference to FIGS. 22 to 25. In FIG. 22, 20 is a rack, and 1 is a rack base which is the basis of the rack 20. The rack base 1 is composed of a base frame 2 and a plate 3. Reference numeral 5 is a subframe, and 4 is a joint plate that connects the base frame 2 and the subframe 5 and serves as a mounting portion for mounting the rack. Although not shown in FIG. 22, reference numeral 6 is a reinforcing frame located below the plate 3 for reinforcing the plate 3. A stand 7 is connected to the joint plate 4 and fixes the rack 20 to the vehicle body. Reference numeral 4a is a connecting member for connecting the joint plate 4 and the stand 7.

Since the rack 20 is composed of one plate 3, even if a load such as a load is applied to a part of the plate 20, the rack 20 does not support the load only by the applied part, but loads the load. Since the racks can be distributed around, it is possible to provide a rack that is stronger than conventional racks. The plate 3 is supported around the periphery thereof by the base frame 2. The base frame 2 joins the plates by welding the entire periphery of the plates. Alternatively, the plate is supported by welding around the plate at regular intervals. The sub-frame 5 has the same shape as the base frame 2, and the joint plate 4 is joined between the base frame 2 and the sub-frame 5 by welding. The joint plate has a flat plate shape and has four holes for screwing or riveting, and the stand 7 is connected using these holes. As shown in the figure, the stands 7 are arranged in a total of 6 on each of the left and right sides of the vehicle body, and are joined together using the four holes of the joint plate 4. Attached using fasteners. The reinforcing frame 6 is provided between the base frames 2 and is used for reinforcing the plate 3 and the base frame 2. The reinforcing frame 6 is welded to the base frame at both ends, and also welded to the plate 3. As shown in the sectional view of FIG. 24, the base frame 2 and the sub-frame 5 are made of pipes having a circular cross-section, and the ends of the pipes are welded to each other. The state is maintained. Further, FIG. 25 shows a connecting portion of each component, and the coupling of each component is welded.

Next, the rack mounting device shown in FIG. 24 will be described. As shown in FIGS. 23 and 24, the rack 20 is attached to the roof of the automobile by J-bolts and fittings. The stand 7 has two holes for attaching J bolts, and two J bolts are attached to one stunt. Thus, the use of two J-bolts is to prevent the rack from falling from the roof of the automobile.

FIG. 26 is a diagram showing a conventional rack mounting device. There is no rain garter on the vehicle body 10. For such a vehicle body, the rack-to-vehicle rack mounting device fixes the rack mounting device to the roof of the vehicle body by pressing the hook 9 against the recess 101. The hook 9 is fixed to the stand 7 with a screw 12. By tightening the screw 12, the hook 9 is pulled toward the stand and fixed to the recess 101. That is, by tightening the screw 12, a force indicated by an arrow P3 is generated on the stand, and this force becomes a force indicated by an arrow P4, and the hook is fastened to the vehicle body. 27 is a diagram showing another example of a conventional rack mounting device. By tightening the screw 12, similarly, the force indicated by the arrow P3 is generated, and the force indicated by the arrow P4 can be generated on the hook 9.

[0008]

[Problems to be solved by the device]

 The conventional rack has a problem that it takes time and labor to manufacture the rack. Since the base frame and sub-frame are constructed using pipes, the work of welding the joint plate to the outer periphery of the pipe and positioning the end of the joint plate and the plate on the pipe-shaped frame for welding There was a problem that accuracy was required and a lot of time and labor was required.

Further, there is a problem in that welding must be stopped at many places. For example, FIG. 28 is a diagram showing a position where a rack is welded. The subframe and base frame form a closed loop by welding the frame parts together. Further, the plate 3 and the base frame are welded to the entire circumference of the plate or at many places. Further, the joint plate is welded to the base frame and the subframe. These numerous weld stop marks are detrimental to the straightness and curvaceousness of the rack. In particular, after welding is stopped, unevenness is generated, and even if paint is applied, the appearance of the weld stop can be clearly seen from the appearance.

Also, it is necessary to provide racks of different sizes such as short or long depending on the size of the roof of the automobile. In order to manufacture a rack to match these sizes of shorts and longs, individual parts had to be designed and manufactured.

Further, as described above, the rack mounting device is mounted on the roof of the automobile using the J bolt and the mounting bracket, but the J bolt, the mounting bracket, and the nut are directly visible in the external appearance, and the rack is In many cases, the aesthetics of the installed car was impaired. In addition, since the mounting bracket and the like are also formed by welding, there is a problem in that it takes time and labor to manufacture the rack mounting device.

Further, in the conventional rack, when the rain garter is present on the roof of the automobile, the roof can be securely fixed using the rain garter. However, many recent automobiles do not have a rain garter, and there has been a demand for a rack mounting device that securely mounts a rack without a rain garter and does not spoil the appearance.

Further, since the conventional rack mounting device is configured as described above, by tightening the screw, the hook is moved in the direction shown by the arrow S as shown in FIGS. 26 and 27. A sliding force is generated. That is, the tightening force of the screw 12 does not become the force for tightening the vehicle body as it is, but it does not change to the force for sliding the hook, resulting in waste. Due to this waste, the conventional rack mounting device has a problem that the rack cannot be securely mounted. In particular, when the screw is tightened, the shape of the hook 9 is deformed as the screw is tightened, and eventually the hook is damaged or the hook is disengaged from the recess.

The present invention has been made to solve the above problems, and an object thereof is to facilitate manufacture and assembly of a rack and a rack mounting device.

Another object of the present invention is to provide a rack and a rack mounting device in which the number of welding stoppers is minimized.

Another object of the present invention is to improve the appearance of the rack and the rack mounting device.

Further, the present invention has an object to make the parts common even when manufacturing racks of different sizes.

Another object of the present invention is to provide a rack mounting device for securely fixing a rack to a vehicle without a rain garter.

【Example】

 Example 1. FIG. 1 is a plan view of a rack according to an embodiment of the present invention. FIG. 2 is a side view in which the rack shown in FIG. 1 is attached to a vehicle body using a rack attaching device. FIG. 3 is a cross-sectional view of the rack shown in FIG. FIG. 4 is a sectional view of the rack shown in FIG. 1 taken along the line BB.

In FIG. 1, AF is an arm frame that constitutes a linear portion of the sub-frame 5 (or the base frame 2). CF is a corner frame that constitutes a corner of the sub-frame 5 (or the base frame 2). B is a bush that connects the ends of the arm frame AF and the corner frame CF. Reference numeral 4 is a joint plate for fixing the sub-frame 5 and the base frame 2 and for connecting the arm frame AF and the corner frame CF.

FIG. 5 is a diagram showing a connecting portion between the arm frame AF and the corner frame CF. In FIG. 5, the role of the bush B will be briefly described. Actually, as described later, the cross section is not a circle and is provided with a recess described later, but in FIG. 5, the case where the cross section is circular is shown and the recess is not shown for easy understanding. As shown in FIG. 5, the bush connects the arm frame AF and the corner frame CF. The cross sections of the arm frame and corner frame are the same, and so is the cross section of the bush. The arm frame AF and the corner frame CF are made of pipes. Therefore, the bush B is provided on both sides with a coupling portion B1 for fitting the arm frame and the hollow portion of the corner frame. Therefore, when connecting the arm frame and the corner frame, it is sufficient to move the arm frame and the corner frame in the direction of arrow X shown in FIG. As a result of the arm frame and the corner frame being fitted to the bush, the arm frame and the corner frame are prevented from being displaced in the radial direction as shown by the arrow Y or the arrow Z, for example.

FIG. 6 is a diagram showing the role of the joint plate 4. The arm frame, the corner frame and the bush have a concave portion 21, and the concave portion 21 fits the end portions of the joint plate. After fitting the joint plate in the recess 21, the joint plate and the arm frame or the joint plate and the corner frame are welded and fixed. Reference numeral 41 is a welded portion which is welded. Incidentally, this welding is performed only inside the rack. Welding is not stopped on the outside. As described above, the joint plate and the arm frame and the joint plate and the corner frame are welded to each other, so that the arm frame and the corner frame do not come off in the arrow X1 direction.

The arm frame and the corner frame are made of aluminum. On the other hand, the bush may be made of aluminum as well. Alternatively, it may be made using a hard rubber. The bush B is preferably made of hard rubber to facilitate the assembly and to absorb manufacturing size deviations of the arm frame and the corner frame. However, as described above, since the bush B is positioned in the direction of the arrow Y or the direction of the arrow Z by the connecting portion B1 of the bush B, it is necessary that the hard rubber is durable and does not deteriorate due to aging.

In FIG. 5 described above, the case where the cross section of the bush is the same as the cross section of the arm frame and the corner frame is shown, but as shown in FIG. 7, the sizes may be different. In the case shown in FIG. 7, the bush is made larger in diameter than the arm frame and the corner frame. The arm frame and the corner frame are connected inside the bush. As described above, when the size of the bush is large, the cutting 42 may be provided on the joint plate 4 so that the bush B and the joint plate 4 do not collide with each other. Further, the example shown in FIG. 7 shows an example in which the arm frame AF and the corner frame CF are not provided with the recess 21. Therefore, the joint plate 4 is welded to either of the outer circumferences of the arm frame and the corner frame. This welding is done only inside the rack. The outside is not welded.

FIG. 8 is an enlarged view showing the internal structure of the rack 20 and the rack mounting device 30. Recesses 21 are provided in the base frame 2 and the sub-frame 5, respectively, and the joint plate 4 is fitted thereto. The joint plate 4 is fixed to the base frame 2 and the sub frame 5 by the welded portion 41. This welded portion 41 exists only inside the rack. Further, the base frame 2 has a plate groove 22 to which the plate 3 is fitted. Only by fitting the periphery of the plate 3 to the plate groove 22, the plate 3 can be fixed to the base frame 2 without welding. In order to steadily perform the fixing, it is desirable to provide the plate groove 22 on the entire inner circumference of the base frame 2. The plate 3 is fixed to the reinforcing frame 6 with rivets 31. In this way, the plate 3 is attached to the base frame and the reinforcing frame without any welding points. In addition, in this example, the case where the stacking portion is plate-shaped (plate) is shown, but it may be sludge-shaped, mesh-shaped, or net-shaped. Incidentally, the reinforcing frame and the plate may be coupled with each other using an adhesive or the like instead of using the rivet 31. Alternatively, they may simply be in contact with each other without being combined.

The sub-frame 5 has a groove 52 having a convex hollow section. The groove 52 is used when an additional crossbar or a member for system upgrade is attached to the rack. FIG. 9 is a diagram illustrating a method of using the groove 52. Reference numeral 53 is a nut having a parallelogram shape. When the width of the nut 53 is W2, the height is W3, and the width of the opening of the groove 52 is W1, the relationship between these three widths is W2 <W1 << W3. Therefore, when inserting the nut into the groove, the nut is fitted into the groove using the width W2 and then rotated as shown by the arrow R. As a result, since the height W3 of the nut is larger than the width W1 of the opening of the groove, the nut cannot be pulled out from the groove. In this state, bolts, crossbars, etc. can be attached to the screw holes 54 provided in the nut. In this way, by using the groove 52, the user can mount the nuts at appropriate positions and as many as necessary. Therefore, it is possible to easily attach a cross bar to the rack, a member for system up to attach a ski or a bicycle. The groove 52 is not limited to being inside the sub-frame, but may be above, below, or outside. Further, it may not be provided on the entire inner circumference of the subframe. For example, it may be provided only on the arm frame without being provided on the corner frame. It may be located not only in the subframe but also in the base frame.

FIG. 10 is a diagram showing racks of two sizes. In FIG. 10, two types of racks, short and long, are shown. In the case of a short rack, one arm frame is connected laterally. On the other hand, in the case of a long rack, two arm frames are connected laterally. By connecting the arm frames in this way, the size of the frame can be freely changed. Therefore, it is not necessary to separately design a special base frame or subframe for the rack for shorts or the rack for longs. In this way, by making the parts common, the production cost can be reduced.

Next, the material of the rack will be described. The base frame 2, the subframe 5, and the reinforcing frame 6 are made of a corrosion-resistant aluminum alloy called A6063. The plate 3 is made of a corrosion resistant aluminum alloy called A5052. As described above, all the materials of the rack 20 in this embodiment are made of a corrosion-resistant aluminum alloy, so that the rack 20 does not corrode and does not rust even if it is used for a long time or exposed to rain or wind. have.

Example 2. Returning to FIG. 8 again, the rack mounting device will be described. In FIG. 8, 10 is a vehicle body, 101 is a recess provided on the side of the vehicle body, and 102 is a car door or window. The rack mounting device 30 is roughly composed of a stand 7, a bracket 8 and screws 12. The stand 7 has a contact portion 7j that contacts the roof of the vehicle body. The contact portion 7j of the stand is attached to the roof of the vehicle body via the rubber plate 13. The rubber plate 13 is provided so as not to damage the roof of the vehicle body, and has a recess 13a of several mm for accurately positioning the contact portion 7j.

When the rack mounting device 30 is mounted, the bracket 8 becomes a portion visible from the outside. The stand and screws are hidden behind the bracket 8 and cannot be seen from the outside. Therefore, the appearance of the rack mounting device is improved. Further, the stand and the bracket have no portions to be welded and formed, and are manufactured by cutting a stand material having a length of 4 m and a bracket material having a length of 4 m into a width of about 10 cm. Therefore, the manufacture of the stand and the bracket is very easy. The screw 12 is composed of a commercially available bolt and a commercially available handle, and can be inexpensively and easily manufactured. The outside of the bracket 8 has a design, which further improves the aesthetics of the rack mounting device.

The rubber plate 13 also has a role of absorbing the inclination of the roof of the car. For example, as shown in FIG. 2, when the roof of the car does not exist parallel to the contact portion 7j of the stand, the thickness of the rubber plate is changed to adjust the inclination. Therefore, by changing the shape of the rubber plate even when the stand 7 is manufactured uniformly, the stand can be securely attached to the roof even if the shape of the roof is changed.

Further, the stand 7 has a frame fixing portion 7a for mounting a frame. The frame fixing portion 7a is fixed to the frame with bolts 15 and nuts 16. The frame receiver 7e on the upper part of the stand is formed along the outer peripheral portion of the base frame 2. Therefore, once the base frame is attached to the stand, the lower half of the outer periphery of the base frame 2 is securely fixed in a shape fitting to the upper part of the stand.

The stand 7 has a tapered portion 7c. The tapered portion 7c has an angle of 30 degrees with the axial direction of the screw 12. The stand 7 also has through holes 7b and 7g through which the screws 12 pass. The diameters of the through holes 7b and 7g are larger than the diameter of the screw 12. Moreover, the stand 7 has a curved portion 7 f that matches the shape of the bracket 8. The curved portion 7f has a smooth concave portion with respect to the bracket 8 so as not to prevent the position of the bracket 8 from changing and to prevent the bracket 8 from coming into contact with the bracket 8 even when the position of the bracket 8 is slightly displaced. It has a curved surface.

The screw 12 has an engaging portion 12a. By rotating the screw 12, the position of the bracket 8 can be moved in the directions of arrows L1 and L2 shown in FIG. Further, the screw 12 has a handle 11. The handle 11 is provided in order to rotate the screw 12 with bare hands without using a tool. Since the handle 11 is attached to the inside of the rack, it has the drawback that it is difficult to work, but it has the effect of improving the appearance and preventing the rack from being stolen easily from the outside. From the viewpoint of theft prevention, the handle 11 may be omitted and the handle 11 may be detachable.

The bracket 8 has a convex portion 8 a at a portion corresponding to the tapered portion 7 c of the stand 7. The convex portion 8a slides on the taper portion by hitting the taper portion 7c and tightening a screw.

On the other hand, the bracket 8 has a hook 9 via a rivet 17. The hook 9 is for hooking the hollow 101 of the vehicle body. The recess 101 is provided in the gap between the window 102 or the door 102. Therefore, the thickness of the hook 9 is preferably about 1 mm to 2 mm even if it is thick so that it can be applied to a narrow gap. Further, since a large pressure is applied to the hook 9, it is necessary to use a durable material. For example, it is desirable that the bracket 8 is made of an aluminum alloy and the hook 9 is made of stainless steel which is stronger than that.

The bracket 8 has a body whose side cross section is arcuate. The body portion of the bracket 8 has a tightening portion that engages with a screw. The tightening portion has a shaft 14 and a shaft receiver 8c that rotatably holds the shaft 14. The shaft receiver 8c further has a through hole 8b through which the screw 12 passes. The through hole 8b has a diameter similar to or larger than the diameter of the through hole 7g described above, and has a diameter larger than the diameter of the screw 12. The shaft 14 has a cylindrical shape whose side cross section is circular, and is attached so as to be rotatable inside the shaft receiver. The shaft 14 is provided with a screw hole 14a for engaging with the engaging portion 12a of the screw 12. As the screw 12 rotates, the degree of engagement between the engaging portion 12a and the screw hole 14a changes, and as a result, the bracket 8 moves in the direction of arrow L1 or L2.

Next, each part used in the rack mounting device 30 is shown in FIGS. 11 to 14, respectively. FIG. 11 is a diagram showing the bracket 8. The bracket is made of A6063S-T5 corrosion resistant aluminum alloy. The bracket is made of a bracket material having a length of 4 m and cut into a width of 10 cm to be used. The surface of the bracket is anodized. After being cut to a width of 10 cm, a hole for hitting the rivet 17 and a through hole 8b are formed to complete the bracket.

FIG. 12 is a diagram showing the stand 7. The stand 7 is made of a corrosion-resistant aluminum alloy called A6063S-T5. The stand is produced as a stand material with a length of 4 m. The surface is anodized. By cutting the stand material having a length of 4 m into a width of about 10 cm, a stand as shown in FIG. 12 can be obtained. After cutting to a width of about 10 cm, a bolt hole 7h is opened in the frame mounting portion and a through hole 7g is opened to complete the stand.

FIG. 13 is a diagram showing a hook. The hook is made of stainless steel called SUS304CP. Although only one kind of hook is shown in the figure, this rack mounting device can be applied to various vehicle bodies by changing the length of the hook.

FIG. 14 is a diagram showing a shaft. The shaft is made of stainless steel called SUS303. The hook and shaft are made of stainless steel material, and are characterized by corrosion resistance and rust resistance.

FIG. 15 is a diagram showing the function of the shaft. If the vehicle body 10 has a different shape, the position of the bracket must change. Even if the position of the bracket changes, the screw hole 14a of the shaft 14 can always maintain the correct positional relationship with the engaging portion 12a of the screw 12 by the rotation of the shaft 14. Therefore, by rotating the screw 12, the shaft 14 can be moved exactly in the axial direction of the screw, and as a result, the rotational movement of the screw with respect to the bracket can be changed to the linear movement of the bracket. Become. If the shaft does not rotate, the screw hole 14a provided in the shaft will be inclined with respect to the axial direction of the screw 12, and the engaging portion 12a and the screw hole 14a will not engage properly, and the mounting operation will be difficult. It will be very difficult. Further, FIG. 15 shows a case where the length of the hook is changed. By changing the shape, length, and bending angle of the hook, it is possible to flexibly attach to various roofs without changing the shape of the stand and bracket. The hook can be replaced by a rivet 17.

FIG. 16 is a diagram showing the operation of the bracket and the tapered portion. The taper portion 7c has an angle of 30 degrees with respect to the axial direction of the screw (direction of arrow M). Therefore, when the bracket moves in the direction of arrow M, the convex portion 8a of the bracket moves in the direction of arrow N. When the convex portion 8a slides in the direction of arrow N, a force P1 is generated on the vehicle body side portion and a force P2 is generated on the vehicle body roof direction. On the other hand, the hook 9 also moves in the direction of arrow Q. When the hook 9 slides in the direction of arrow Q, a force P3 is generated on the vehicle body side portion and a force P4 is generated on the vehicle body roof direction. The forces P1 and P3 securely fix the stand in the lateral direction. Also, due to the forces of P2 and P4, the stand is securely fixed to the roof of the car. The body of the bracket 8 is formed in an arcuate shape (arc shape), and by pressing the arc-shaped inner side of the body in the direction of the arrow M, the protrusion 8a and the hook 9 at both ends of the body of the bracket are hooked. To generate lateral and vertical forces. As a result, it is securely fixed to the stand roof. It should be noted that the shaft 14 is provided above the center of the body because the roof is formed at the bottom of the body, but it is desirable that the shaft 14 be located in the center of the body as much as possible.

In this example, the angle of the taper portion is 30 degrees, but the angle of the taper portion is changed according to the weight of the rack to be attached and the shape of the recess of the vehicle body, and the same rotational force as described above is used. The force of P1 and P2 can be adjusted. For example, when the inclination angle is 45 degrees, the lateral force and the longitudinal force are divided into two equal parts. Since the rack itself has its own weight, it is desirable to prevent the rack from falling from the vehicle body by taking a greater lateral force than a longitudinal force. Therefore, it is considered that the angle of the taper portion with respect to the axial direction of the screw is preferably 20 to 40 degrees. The direction in which the hook 9 moves (the direction of the arrow Q) differs slightly depending on the vehicle body, but the angle α formed by the arrow Q and the arrow M is the angle formed by the taper portion in order to make P2 and P4 equal (see the figure). It is desirable that it is approximately the same as 30 degrees).

Example 3. In the above embodiments, the joint plate 4 is used to connect the arm frame AF and the corner frame CF, but the one connecting the arm frame and the corner frame may not be the joint frame. For example, the stand 7 of the rack mounting device shown in the second embodiment may be used. The stand 7 has a frame connecting portion 7a as shown in FIG. There are two bolt holes 7h for passing the bolts 15 in the frame joint portion. Therefore, the two bolt holes 7h may be used to fix the arm frame and the corner frame, respectively, as shown in FIG. Since the frame receiver 7e of the stand 7 is designed to match the lower half of the frame, it can be sufficiently fixed by the stand 7.

As described above, it is possible to connect the frames using the stand 7 without using the joint plate 4. In particular, in the case of a rack or the like in which it is not necessary to provide the subframe 7 and the joint plate, the frame can be connected by using a rack mounting device. Although FIG. 17 shows an example in which the stand 7 and the frames AF and CF are fixed by bolts and nuts, they may be fixed by welding. Also, when connecting the frames using a stand, the bush B may be placed between the frames as shown in FIG.

Example 4. In the above embodiment, the joint plate 4 is used to join the arm frame AF and the corner frame CF by welding. However, the joint plate 4 and the arm frame AF are joined together, and the joint plate 4 and the corner frame CF are joined together. The connection may be made with bolts and nuts. 18 and 19 show a case where the joint plate is connected to the base frame 2 and the sub-frame 5 by bolts and nuts. As shown in FIG. 18, the plate 3 is provided with a cutout portion 3a for passing the joint plate 4 inside the base frame. The joint plate 4 is processed so that its side surface has a pan-bottom shape in order to be connected to the base frame and the sub-frame. The joint plate 4 and the subframe 5 are connected by a bolt 15a and a nut 53. At that time, the joint plate 4 can be coupled to the sub-frame 5 by using the above-mentioned convex groove 52. Further, the joint plate 4 and the base frame 2 are connected by a bolt 15b and a nut 16b. As described above, by using the bolt and the nut, the arm frame AF and the corner frame CF can be coupled more reliably. Further, since the joint plates are all connected inside the sub-frame and the base frame, the appearance is not spoiled. Further, as shown in FIG. 19, a snap pin 7s may be provided on the shaft of the screw 12 to prevent the screw 12 from coming off the stand 7. By making the length of the snap pin 7s larger than the diameter of the through hole 7b, the snap pin 7s cannot pass through the through hole 7b, and the screw 12 does not come off from the stand 7.

Although not shown, a spring may be provided between the bracket 8 and the stand 7 so that the bracket is automatically separated from the stand when the screw is loosened. Since the bracket is away from the stand, the rack mounting device can be easily attached and detached.

As described above, this embodiment is the rack provided with the plate 3 on which the load is placed and the base frame having the connecting portion connecting the ends of the frame parts such as the arm frame and the corner frame. It is characterized in that it is provided with a bush for connecting the end of the frame component to the connecting portion, and a joint plate 4 or a stand 7 fixed to the end of each frame.

Further, the rack further includes a sub-frame at a position distant from the base frame, and the sub-frame connects the end portions of the frame with a bush and connects the frame end portions with the joint plate. It is characterized in that it is fixed and the subframe is fixed to the base frame.

Further, the joint plate and the end of the frame are welded inside the rack.

Further, the component frame is characterized by having a recess for engaging the end of the joint.

Further, in the above-described embodiment, the rack attaching device for attaching the article to the article to be attached is provided with the stand having the abutting portion that abuts the article to be attached and the taper portion having a predetermined angle. It is characterized by

Further, the present invention is characterized by including a hook portion that comes into contact with a side portion of the attachment object, a convex portion that slides on the inclined portion, and a bracket that has a body portion between the hook portion and the convex portion. To do.

Further, the bracket is connected to the stand, the convex portion is slid along the inclination of the taper portion, and the hook portion is pressed against the side portion of the attachment object. Is provided with a connecting means for connecting to the stand.

Further, the body portion has a through hole, the body portion has a shaft rotatably attached to the body portion, and the coupling means is provided with the shaft through the through hole. It is characterized by having a bolt that pulls the shaft toward the body.

As described above, according to this embodiment, the arm frame and the corner frame are not welded. In addition, the frame sizes can be easily changed by connecting the arm frames to each other. Further, by forming the bush with hard rubber or the like, the arm frames can be easily connected to each other or the arm frame and the corner frame can be easily connected. Further, the welding of the joint plate and the arm frame or the joint plate and the corner frame is performed only inside the rack. Therefore, the appearance of the rack is improved. Further, since the plate 3 is fitted into the groove of the frame and attached, it is not necessary to stop the plate by welding. Further, since the joint plate is welded after being fitted into the recesses provided in the arm frame and the corner frame, the welding position can be easily specified, and the welding work can be performed quickly and accurately. Thus, this embodiment is intended to facilitate the assembling and improve the aesthetics of the rack. Moreover, by making the parts common, it is possible to manufacture a rack at low cost.
