Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a slide hook used when suspending a frame or the like in an art museum or a gallery.

[0002]

[Prior art]

 A commonly used slide hook is shown in FIG. As shown in the figure, this slide hook comprises a hook body 21 slidably mounted on a rail 40 and a nut 22 provided on the hook body 21.

The rail 40 has a pair of side plates 41, and flanges 42 formed inward from the lower edges of the side plates 41, respectively.

The hook body 21 has an engaging head portion 24 continuously connected to an upper end of a shaft portion 23 having an outer diameter smaller than a space between the flanges 42 of the rail 40, and a hook portion 25 continuously connected to a lower end of the shaft portion 23. It has a composition that

The dimension between both ends of the engaging head portion 24 is larger than the distance between the flanges 42 of the rail 40 and smaller than the distance between the side plates 41. The dimension between the two sides of the engagement head 24 is smaller than the distance between the flanges 42. A threaded portion 26 threadably engaged with the nut 22 is provided on the outer periphery of the shaft portion 23, and the outer diameter of the threaded portion 26 is smaller than the dimension between both ends of the engaging head portion 24.

In order to attach the slide hook to the rail 40, the both sides of the engaging head portion 24 are aligned with the width direction between the flanges 42 of the rail 40, and the engaging head portion 24 is inserted between the flange portions 42. , Rotate the hook body 21 by 90 °. After that, the slide hook is slid to a predetermined position, and the flange 42 is tightened by the nut 22 and the engaging head portion 24. A washer 27 is sandwiched between the nut 22 and the flange 42.

[0007]

[Problems to be solved by the device]

 When manufacturing the slide hook, since the outer diameter of the screw portion 26 is smaller than the dimension between both ends of the engaging head portion 24, the nut 22 can be inserted into the hook body 21 from above. Since the rod-shaped member that is the material of the hook body 21 has the engaging head portion 24 formed in advance at the upper end portion thereof, the nut 22 is inserted into the rod-shaped member from below before the hook portion 25 is formed, and then, The lower end of the rod member must be bent to form the hook 25.

Therefore, the hook portion 25 cannot be formed in advance by casting or the like, and the cross-sectional area of the hook portion 25 cannot be increased so much that the heavy load cannot be endured. .

Further, since the rod-shaped member has to be bent with the nut 22 attached, it is difficult to manufacture.

Therefore, it is an object of the present invention to provide a slide hook that can withstand a large load and is easy to manufacture.

[0011]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention comprises a hook body slidably attached to a rail having a flange formed inward from the lower edges of a pair of side plates, and a nut provided on the hook body. In the slide hook, in the hook body, a small diameter portion having an outer diameter smaller than the interval between the flanges of the rails is continuously provided at the upper end of the shaft portion, and an engaging head portion is continuously provided at the upper end of the small diameter portion. A hook is connected to the lower end of the engaging head, and the dimension between both ends of the engaging head is larger than the distance between the flanges of the rail and smaller than the distance between the side plates. Make the dimension between both sides smaller than the spacing between flanges, and provide a threaded portion on the outer periphery of the shaft portion that engages the nut with the screw. This is the structure adopted.

[0012]

[Action]

 Since the outer diameter of the threaded portion is equal to or greater than the dimension between both ends of the engaging head portion, the nut can be inserted into the hook body from above.

Therefore, at the time of manufacturing, it is not necessary to insert the nut from below the hook body, and the hook portion can be formed in advance by casting or the like, and the cross-sectional area of the hook portion can be increased. .

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1 to 3, the slide hook according to the present invention comprises a hook body 1 slidably mounted on a rail 40 and a nut 2 provided on the hook body 1. The rail 40 is the same as that shown in FIG.

In the hook body 1, a small diameter portion 4 having an outer diameter smaller than a space between the flanges 42 of the rail 40 is continuously provided at an upper end of the shaft portion 3, and an engaging head portion 5 is continuously provided at an upper end of the small diameter portion 4. However, the hook portion 6 is connected to the lower end of the shaft portion 3.

The dimension between both ends of the engaging head 5 is larger than the distance between the flanges 42 of the rail 40 and smaller than the distance between the side plates 41. The dimension between both sides of the engagement head 5 is smaller than the distance between the flanges 42. Screws 8 that are screw-engaged with the nut 2 are formed on the outer diameter surfaces of both ends of the engaging head 5.

A threaded portion 7 threadably engaged with the nut 2 is provided on the outer periphery of the shaft portion 3, and the diameter of the threaded portion 7 is the same as the diameter of the screw 8.

The outer diameter of the screw portion 7 may be larger than the dimension between both ends of the engaging head portion 5, and in this case, the screw 8 is unnecessary.

Further, the shape of the engaging head portion 5 may be a shape in which both side portions of a cylinder are cut off as shown in the figure, or may be an elliptical cross-sectional shape.

To attach the slide hook to the rail 40, the engaging head 5 is inserted between the flanges 42 by aligning the short direction of the engaging head 5 with the width direction between the flanges 42 of the rail 40. After that, the hook body 1 is rotated by 90 °. After that, the slide hook is slid to a predetermined position, and the nut 42 and the engaging head 5 tighten the flange 42. A washer 9 is sandwiched between the nut 2 and the flange 42.

In the slide hook as described above, since the nut 2 can be inserted into the hook body 1 from above, it is not necessary to insert the nut 2 from below the hook body 1 at the time of manufacturing, and the hook 2 is previously hooked by casting or the like. The section 6 can be formed and the cross-sectional area of the hook section 6 can be increased.

[0022]

【effect】

 According to this invention, as described above, the outer diameter of the threaded portion is made larger than the dimension between both ends of the engaging head portion, so that the nut can be inserted into the hook body from above.

Therefore, at the time of manufacturing, it is not necessary to insert a nut from below the hook body, and the hook portion can be formed in advance by casting or the like, and the cross-sectional area of the hook portion can be increased. Therefore, it can withstand a large load.

In addition, it is easy to manufacture.
