Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a clamp cover that is attached to a clamp that is clamped and fixed to a steel pipe when assembling a steel pipe scaffold, and covers a protrusion of the clamp to ensure the safety of passers-by.

[0002]

[Prior art and its problems]

 This type of conventional clamp cover is a cover that is integrally molded of plastic and consists of two cover units that are openably and closably connected by a hinge. Each cover unit has a through hole with a semicircular cross section. When used, both covers that are open are held by clamps that are clamped and fixed in a steel pipe to close them. However, the conventional covers simply use the elastic holding force of the hinge part to close both covers, so that the elastic force of the hinge part deteriorates after being used several times. As a result, even if the covers are attached to the clamps, both covers alone are in a half-open state.

An object of the present invention is to provide a clamp cover that is a plastic cover similar to the above-mentioned conventional cover, but can always reliably close both covers alone even if they are repeatedly used for a long period of time.

[0004]

[Means for Solving the Problems]

In these drawings, reference numeral 1 denotes a clamp cover integrally formed of plastic, which includes two hinge portions 2 which are openably and closably connected to each other. The cover units 3 and 4 are composed of the cover units 3 and 4, and the cover units 3 and 4 are opposite to the through holes 5 and 6 through which the steel pipe P used for a steel pipe scaffold can pass and the side where the hinge unit 2 is provided. Formed on the side, and provided with dividing portions 7 and 8 for opening the through holes 5 and 6 by utilizing the elasticity of the plastic, and at predetermined positions on the peripheral portions of both the cover units 3 and 4, A lockable portion 9 and a locked portion 10 which can be engaged and disengaged with each other are integrally formed so as to connect the covers 3 and 4 to each other by locking them when the covers 3 and 4 are closed. Has been done.

1, FIG. 2, FIG. 4 and FIG. 6 show the normal state of the clamp cover 1. As is apparent from these figures, the hinge part 2 is composed of both cover units 3, 3. 4 is formed by a thin-walled portion having an arc-shaped cross section, which is integrally connected in a state where it is opened in a plane. Further, as is apparent from these figures, this hinge portion 2 has a rotation axis line in a direction perpendicular to the axis line of the steel pipe P which is passed through the through holes 5, 6, and therefore both cover units 3 are provided. , 4 rotate in a direction along a plane parallel to the axis of the steel pipe P.

To describe the structure of the cover 1 in more detail, one cover unit 3 is composed of a bottom wall portion 3a and a peripheral side wall portion 3b, and the through hole portion 5 is provided at the center of the bottom wall portion 3a. Is formed, the dividing portion 7 is formed on the side facing the hinge portion 2 with the through hole portion 5 sandwiched therebetween, and the peripheral side wall portion 3b is cut off at the dividing portion 7 as shown in FIG. Is formed in an upward U-shape, and a pair of locking portions 9, 9 are provided on the outer surface of the peripheral side wall portion 3b close to the opening 11 so as to project outward in a right angle direction. Further, on the upper side of the inner peripheral surface of the peripheral side wall portion 3b, an engaging portion 12 that engages with the later-described engaged portion of the other cover unit 4 is circumferentially provided.

The other cover unit 4 also has a structure similar to that of the cover unit 3, and is composed of a bottom wall portion 4a and a peripheral side wall portion 4b, and the through hole portion 6 is provided at the center of the bottom wall portion 4a. The dividing portion 8 is formed on the side facing the hinge portion 2 with the through hole portion 6 interposed therebetween, and the peripheral side wall portion 4b is cut off at the dividing portion 8 so that the upward U-shaped opening portion 13 is formed. And a pair of locked portions 10, 10 projecting outwardly at right angles to the outer surface of the peripheral side wall 4b near the opening 13, and the one cover is provided on the upper side of the outer peripheral surface of the peripheral side wall 4b. An engaged portion 14 that engages with the engaging portion 12 of the single body 3 is provided around the periphery.

Therefore, as shown in FIGS. 2 and 4, when the cover unit 3 on the left side in the drawings is rotated clockwise around the hinge portion 2 to cover the right side cover unit 4, The engaging portion 12 on the inner side of the peripheral side wall 3b of the single body 3 engages with the engaged portion 14 on the outer side of the peripheral side wall 4b of the cover single body 4, and the upper U-shaped opening portions 11 of both cover single bodies 3 and 4 are provided. 13 are aligned from above and below to form a rectangular opening. As will be described later, this rectangular opening will be fitted to the connecting portion of the two pipe clamps when the cover is used.

Further, the details of the engaging portion 9 and the engaged portion 10 which are provided on both cover units 3 and 4 and which can be engaged and disengaged with each other will be described. Each engaging unit provided on one cover unit 3 9 has a locking head 15 (see FIG. 8) that is substantially semicircular in both plan view and front view, and has a locking step portion 16 (see FIG. 8) at the lower inner end of this locking head 15. Is forming. Each of the locked portions 10 has a locking hole 17 (see FIG. 7) that can be fitted into the locking head 15 of the locking portion 9. Then, when connecting the closed cover bodies 3 and 4 together, as shown in FIG. 7, when the cover body 3 and 4 are closed, the locked portion 10 of the cover body 4 is made elastic. While bending at a right angle to the cover unit 3 side against the force, the locking hole 17 of the locked portion 10 is fitted into the locking head 15 of the cover unit 3, and the phantom line in FIG. Thus, the inner end of the locking hole 17 is locked to the locking step portion 16 of the locking head 15. In this case, since an elastic restoring force acts on the locked portion 10, it does not easily come off from the locking portion 9. As a result, both cover units 3 and 4 are connected to each other.

In the use of the clamp cover having the above-described structure, for example, as shown in FIG. 9, two clamp pipes are connected to each other at right angles to each other and sandwiched and fixed between the vertical and horizontal steel pipes P, P. The clamp covers 1 are attached to the clamps K and K, respectively. When the clamp cover 1 is attached to the clamps K, both cover units 3 and 4 are applied to the steel pipe P in the normal state, that is, in the state of being opened in a flat state. By using the elasticity of the plastic to pull open the dividing parts 7 and 8 of No. 3, and by fitting the respective cover units 3 and 4 into the steel pipe P from the opened dividing parts 7 and 8, the clamp K is as shown in FIG. Then, it is in a state of being covered with this cover 1. In this case, the U-shaped openings 11 and 13 of both cover units 3 and 4 are fitted from both sides to form a rectangular opening, and the rectangular opening is connected to the connecting portion of the two pipe clamps K and K. Make it fit. In this way, after the cover units 3 and 4 of the respective clamp covers 1 are covered on the respective clamps K, the engaging portion 9 on one cover unit 3 side and the engaged portion 10 on the other cover unit 4 are engaged with each other. Stop them and connect both cover units 3 and 4 in the closed state.

[0012] In this embodiment, the hinge portion for connecting the both cover bodies so as to be openable and closable is formed by the thin wall portion for integrally connecting the both cover bodies in a state where the both cover bodies are opened in a flat state. May be formed separately from both covers, or both covers may be normally closed. However, as in this embodiment, when both covers are connected so as to be opened in a plane, the covers are fitted to each other when the covers are not used, for example, when a number of covers are packed in a box. When stacked, the stacking work is easy, and the bulk of the stacked state is low, which is convenient for transportation and storage.

[Operation and effect of the device]

According to the clamp cover of the present invention, when the both covers are closed, the locking part and the locked part formed around the both covers are locked to each other. Even after repeated use over a long period of time, both covers can be reliably connected to each other, and thus the function as a clamp cover can be fully exerted.

In addition, the hinge portion connecting both covers alone is formed by a thin portion that integrally connects both covers alone in a state where the covers are opened in a plane, so that when not in use, for example, when the covers are packed in a box. When a number of covers are fitted to each other and stacked, the stacking process is easy and the bulk of the stacked state is low, which is convenient for transportation and storage.
