Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

  The present invention can be locked to a desk or counter that is composed of a top plate and a frame such as a pipe. It depends on the hooks and pipes used, and more specifically on the pipe (frame) Once attached, the hook does not fall out between the pipe and It belongs to the technical field of drop-out prevention hooks and pipes used.

[0002]

[Prior art]

  On the side of the desk consisting of the top plate and the pipe frame (legs), place something such as a bag A general hook that is fixed and used for hooking, and a frame (round pipe) The structure of is shown in FIGS. 9 and 10.

[0003]   The hook a is a hooking lower part b and a hanging part that stands up from both ends of the base end of the hooking lower part b. The straight parts c, c and the locking parts that extend straight in the horizontal direction from the upper ends of the vertical parts c, c It is composed of parts d and d. On the other hand, the round pipe f has Grooves g and g are respectively provided at the positions where the two horizontal locking upper portions d and d of the hook a are locked. Preformed accurately in the transverse direction.

[0004]   Therefore, when the hook a is attached and the desk is manufactured, the circular pipe f is placed at a predetermined position. The horizontal locking upper portions d, d of the hook a are placed in the groove portions g, g formed in the . Next, an arrangement in which the side surface portion n of the container k is brought into contact with the vertical portions c, c of the hook a And the upper edge portion m of the container k is fixed to the upper portions d and d of the hook a and the round pipe f. Position in a covering arrangement from above. And above the hook a (case k) Cover the top plate e. Finally, screw the screw s into the top plate e from below the round pipe f. The hook a is fixed by the top plate e, the round pipe f, and the storage container k. It is attached so as to sandwich it.

[0005]

[Problems to be solved by the device]   In the conventional structure of the hook a and the pipe f, the existence of the container k is indispensable. This is because the hook a has the engaging upper portions d, d inserted through the grooves g, g of the round pipe f. It is only constrained in the state (Fig. 10), and its locking upper parts d, d are horizontal. Since it is just formed straight, there is no storage box k When trying to hook on the lower part b for hooking, hook inward in the direction indicated by t in the figure. a moves and eventually falls out.

[0006]   Therefore, the storage compartment k was required to prevent the hook a from coming off. The position to attach the quadruplet and its shape were limited. Also, the shape of the container k is limited. Since there is no flexibility in designing the desk, work man-hours and production costs can be reduced. could not.

[0007]   Therefore, the object of the present invention is to reduce the number of parts in the production of desks and the like equipped with hooks. In addition to reducing the number of man-hours required for the product, the hook once attached to the pipe frame and top plate It has excellent safety and economic efficiency, and can be applied in a wide range. It is to provide a slip-out prevention hook and a slip-out prevention pipe.

[0008]

And the upper surface 30 of the round pipe 3 has a curved shape. Formed in a groove 31 of a predetermined length into which the two locking upper portions 22, 22 bent into The two curved locking upper portions 22, 22 are formed in the groove portion 3 of the round pipe upper surface 30. When the top plate 1 is covered and fixed from above in a state of being fitted to the hook 1, the hook 2 It is characterized in that it can be prevented from coming off.

[0013]

[Embodiment of device]

  The present invention according to claims 1 to 5 comprises a top plate (deck) and a frame such as a pipe. Attached to the side of a desk, counter, table, workbench, etc. The drop-out prevention hook and the drop-out prevention pipe do not fall out even if you hook something on It Hereinafter, preferred embodiments will be described with reference to the drawings.

[0014]   FIG. 1 shows the relationship between the removal prevention hook and the removal prevention pipe of the present invention.

[0015]   The structure of the detachment prevention hook 2 is shown in FIGS. This slip-out prevention hook 2 is a contract As described in claim 1 and claim 2, usually, by bending one wire, For hooking in which the side view shape is U-shaped so that things such as bags can be hooked The lower part 20 (FIG. 3) and two vertical parts that stand upright from both ends of the base end of the hanging lower part 20. The parts 21 and 21 (FIGS. 3 and 4) and the vertical parts 21 and 21 in the horizontal direction from the upper ends of the parts 21 and 21. It consists of two extended locking parts 22, 22.

[0016]   The two locking upper portions 22 and 22 of the hook 2 are formed by pressing, respectively. It is formed by bending into a V-shaped curve when viewed from the surface direction (FIGS. 3 and 1). Curved The curved shape is not limited to the V shape in the illustrated example, but may be a U shape or It may be S-shaped or a wavy shape in which they are continuous.

[0017]   Next, the structure of the slip-off prevention pipe 2 is shown in FIGS. 7 and 8. This fall prevention pipe 3 As described in claim 3, the two V-shaped locking upper portions 22, 22 of the hook 2 are It is a lockable pipe 3 (see FIGS. 1 and 6). The type of pipe 3 does not matter, It is preferable to use the round pipe 3 as in the illustrated example.

[0018]   As shown in FIG. 1, the upper surface 30 of the pipe 3 has the shape of a cross section as described above. It is formed in a V-shaped groove portion 31 similar to the V-shaped locking upper portion 22 of the hook 2. Well Further, the V-shaped groove portion 31 is provided at least in the V-shaped locking upper portions 22 and 2 of the hook 2. 2 is formed in a concave shape having a length that can be locked from the side (FIGS. 7 and 8) . The concave V-shaped groove portion 31 is also easily formed by pressing. Therefore, before The two V-shaped locking upper portions 22, 22 of the hook 2 are difficult to be seen from the side surface of the round pipe 3. Securely fitted (see FIGS. 6 and 2).

[0019]   Therefore, the above-mentioned curved two locking upper portions 22 and 22 are provided on the round pipe 3. The top plate 1 is covered from above in a state where the top plate 1 is fitted in the groove 31 of the surface 30 and the top plate 1 is screwed on. 1 and the round pipe 3 are fixed (FIGS. 1 and 2).

[0020]   In this state, the curved locking upper portions 22, 22 of the hook 2 are formed on the upper surface 30 of the round pipe. Since it fits snugly into the part 31 and is restrained, things such as bags are pulled randomly. Even if a force is applied in the direction of arrow 5 in FIG. Is held vertically, the curved locking upper part 22 of the hook 2 is the upper surface of the round pipe 3. It is possible to prevent the groove 31 from falling off (see claims 4 and 5). Yo In order to prevent the hook 2 from moving or coming off, It can be used safely for many years without the need for a storage compartment behind it. It

[0021]

[Effect of device]

  According to the inventions of claims 1 to 5, the locking upper part is a V-shaped bay when viewed from the side. The drop-out prevention hook that is bent in a curved shape is especially similar to this V-shaped locking upper part. Suitable for use with a slip-off prevention pipe whose upper surface is formed in a V-shaped groove. Effectively prevent the hook from falling off, and use it on a desk, counter, or workbench. In this case, it contributes to the convenience and safety of accidentally hooking an object on the hook.

[0022]   In addition, there is no need for a storage case when manufacturing desks with hooks or pipe frames. Can be completed with a small number of parts, reducing the number of work steps, expanding the range of applications, and reducing manufacturing costs Also contribute to.
