Abstract

A grating by the present invention prevents a stroller or a shopping cart from rattling when passing through the grating caused by placing multiple second division members at the same height and prevents damage to the grating. The grating prevents skidding by placing the upper end of an antiskid protrusion higher than the upper surface of a first division member and an edge member to increase friction force.

Description

Grating, and manufacturing methods of the same

The present invention relates to a grating, and more particularly, because a plurality of second partition members are located at the same height, it is possible to solve a problem that a baby carriage, a shopping cart, and the like are rattled when the grating passes and a breakage of the grating is promoted. In addition, since the upper end of the anti-slip projection is located higher than the upper surface of the first partition member and the upper surface of the rim member can increase the friction force for grating effective for preventing slipping. The invention also relates to a method for producing such gratings.

In general, the grating is widely used as a cover of a rainwater collecting and draining path installed in roads, residential complexes, subways, etc., and generally includes a plurality of rectangular grids.

The rectangular grid consists of a bearing bar and a crossbar. The bearing bar and the cross bar are installed to divide the rectangular edges of the gratings at right angles to each other. In this case, since the installation intervals of the two bars are different from each other, the completed lattice forms a rectangle.

By the way, the rectangular intervals are sufficiently dense for vehicles such as walkers or vehicles, but large for vehicles with small wheels such as strollers, wheelchairs, suitcases, shopping carts and the like. Thus, when the baby carriage or the like passes through the grating, the wheel is often caught in a rectangular grid. In such a case, the wheels often can not easily come out due to the own weight of the baby carriage or the rigidity of the rectangular grid, and when a force is applied to the baby carriage, the baby carriage or the like often gets injured.

In order to solve this problem, the applicant has devised 'safety grating'. Safety grating is disclosed in Utility Model Registration No. 0328159.

The safety grating, as shown in Figures 1 and 2, the edge member 2 and the plurality of first partition members 4 for dividing the edge member 2 in either the vertical or horizontal direction And a plurality of second partition members 6 for densely dividing the rectangular space 8 formed by the edge member 2, the first partition member 4 and / or the first partition members 4. do. That is, since the safety grating 10 is formed by continuously bending the second partition member 6 along the longitudinal direction, the rectangular space 8 is closely divided, so that the stroller, wheelchair, travel bag, shopping cart, or inline skate grating. You can solve the problem of being stuck in.

The safety grating 10, as shown in FIG. 3, attaches the second partition member 6 to the jig 20 using magnetic force, and then moves the jig 20 upwards from the bottom to the first partition. The second partition member 6 is inserted and installed between the members 4 and between the first partition member 4 and the edge member 2. After the installation, the second partition member 6 is fixed to the first partition member 4 and / or the edge member 2 by spot welding.

However, since the lengths of the plurality of jigs 20 are not equal to each other, as shown in FIG. 4, there is a problem that the top heights of the second partition members 6 may be different from each other. That is, the jig 20 may have different lengths of the rod 21 or the length of the attachment portion 22 due to manufacturing error, operation error, etc., and thus, the installation height of the second partition member 6 may be different from each other. Can be.

As such, if the upper heights of the second partition members 6 are not the same, the stroller, the shopping cart, the roller blade, and the like may rattle when moving on the grating 10, and the problem of the grating 10 being promoted is broken. Occurs.

On the other hand, the anti-slip protrusion (not shown in the figure) is formed on the upper surface of the second partition member (6). The anti-slip protrusion prevents slipping by increasing friction.

However, when the upper end height of the second partition member 6 is not constant, the upper end of the first partition member 4 and the upper end of the edge member 2 may be positioned higher than the upper end of the anti-slip protrusion, thereby preventing slipping. The protuberances can't play a role, and slip accidents often occur.

The present invention has been devised to solve the above problems, and because the plurality of second partition members are located at the same height, it is possible to solve the problem that the stroller, the shopping cart, etc. are rattled when passing over the grating and the breakage of the grating is promoted. The upper end of the anti-slip protrusion is located above the upper surface of the first partition member and the upper surface of the rim member, so that the friction force can be increased, and the object thereof is to provide an effective grating for preventing slipping.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary meanings, and the inventor should appropriately interpret the concepts of the terms appropriately It should be interpreted in accordance with the meaning and concept consistent with the technical idea of the present invention based on the principle that it can be defined. Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely examples of the present invention and are not intended to represent all of the technical ideas of the present invention, so that various equivalents And variations are possible.

5 is a perspective view showing a grating according to the first embodiment of the present invention, Figure 6 is a perspective view showing a first partition member provided in the grating.

Referring to the drawings, the grating 100 may include a frame member 30, a plurality of first partition members 40 for dividing an inner space of the frame member 30, and a first partition member 40. The second partition member 50 is provided between the first partition member 40 and the edge member 30.

The edge member 30 is composed of a plurality of side members, for example four side members 31, 32, 33, 34.

Of the four side members 31, 32, 33, 34, the jaw 36 is continuously disposed on the inner side surface of the side members 31, 33 disposed in parallel with the longitudinal direction of the first partition member 40. Is formed. That is, the jaw 36 is continuously formed on the inner surface of the side members 31 and 33 installed to face the side of the first partition member 40.

The jaw 36 supports the second partition member 50 in cooperation with the jaw 46 of the first partition member 40. This will be described in more detail below.

The first partition member 40 is installed in the interior space of the frame member 30 at predetermined intervals. The jaw 46 is formed on both side surfaces of the first partition member 40.

The jaw 46 is formed to be continuously horizontal along the longitudinal direction of the first partition member 40. The jaw 46 is also formed at the same height as the jaw 36.

The second partition member 50 is installed in the rectangular space s formed by the rim member 30 and the first partition member 40 to closely divide the rectangular space s again. The second partition member 50 may have a shape bent in a zigzag. The bent portion 52 is supported by the jaws 36 and 46.

As shown in FIGS. 7 and 8, the second partition member 50 is attached to the jig 20 having magnetic force, and then the jaw 36 is moved by an operation in which the jig 20 moves from top to bottom. 46). After the mounting is performed, the magnetic force is removed, and then the second partition member 50 is fixed to the first partition member 40 and the edge member 30 by spot welding. Accordingly, since the welding is performed after the second partition member 50 is seated on the jaws 36 and 46, the heights of the second partition members 50 are all the same. On the other hand, w denotes a portion where the spot welding is made by way of example.

On the other hand, the second partition member 50 may include a non-slip projection 54 formed on the upper surface. The anti-slip projection 54 is formed to protrude on the upper surface of the second partition member 50 to prevent the sliding by forming a large friction force. At this time, since the upper surface of the second partition member 50, the upper surface of the first partition member 40 and the upper surface of the rim member 30 is located at the same height, the anti-slip projection 54 is the first partition member (40). ) Is positioned higher than the upper surface of the upper surface and the rim member 30, and thus it is possible to properly play the anti-slip role of the anti-slip projection (54). That is, since the heel of the pedestrian or the wheel of the shopping cart or the like preferentially contacts the anti-slip protrusion 54, the frictional force is largely formed, thereby preventing slipping.

As described above, the grating 100 has the same height of the plurality of second partition members 50 and the anti-slip protrusion 54 is higher than the top surface of the first partition member 40 and the top surface of the edge member 30. Because it is located there, strollers, shopping carts, etc. can solve the rattling problem when passing over the grating 100, and can also solve the problem that the breakage of the grating is promoted, and can also prevent slipping.

On the other hand, the jig 20 is a device used when placing or fixing the object to be processed in the correct position. The jig 20 may include an attachment part 22 and a cylinder 24 for reciprocating the attachment part 22. The attachment part 22 may be made of an electromagnet to attach the second partition member 50 by magnetic force. That is, the attachment part 22 attaches and fixes the second partition member 50 when the power is supplied, and is separated from the second partition member 50 when the power supply is stopped. Since the configuration of the jig 20 is already well known and its configuration is disclosed in Korean Patent No. 10-0749477, etc., a detailed description thereof will be omitted.

The grating 200 is formed of the grating 100 except that the thickness D of the lower portion of the jaw 46 in the first partition member 40 is smaller than that of the first partition member 40 of the first embodiment. The configuration and manufacturing method are the same.

On the other hand, Figure 10 is a cross-sectional view showing a grating according to a third embodiment of the present invention, Figure 11 is a perspective view showing a process for manufacturing the grating. 10 and 11, the same reference numerals as the reference numerals of FIGS. 1 to 9 denote the same components having the same role.

Referring to the drawings, the grating 300 may include an edge member 30, a plurality of first partition members 40 for dividing an inner space of the edge member 30, and a first partition member 40. The second partition member 50 is provided between the first partition member 40 and the edge member 30.

The edge member 30 is composed of a plurality of side members, for example four side members 31, 32, 33, 34.

In the four side members 31, 32, 33, 34, the groove 38 is continuously formed on the inner side of the side members 31, 33 disposed in parallel with the longitudinal direction of the first partition member 40. Is formed. That is, the groove 38 is continuously formed on the inner surface of the side members 31 and 33 provided to face the side of the first partition member 40.

The recess 38 supports the second partition 50 in cooperation with the recess 48 of the first partition 40. This will be described in more detail below.

The first partition member 40 is installed in the interior space of the frame member 30 at predetermined intervals. Grooves 48 are formed on both side surfaces of the first partition member 40.

The recess 48 is formed to be continuously horizontal along the longitudinal direction of the first partition member 40. In addition, the recess 48 is formed at the same height as the recess 38.

The second partition member 50 is installed in the rectangular space s formed by the rim member 30 and the first partition member 40 to closely divide the rectangular space s again. The second partition member 50 may have a shape bent in a zigzag. The bent portion 52 is installed to be inserted into the groove portions 38 and 48 and is supported by the groove portions 38 and 48. After the insertion, the second partition member 50 may be fixed to the first partition member 40 and / or the edge member 30 by spot welding. Since the second partition member 50 is inserted into and installed in the recesses 38 and 48, the plurality of second partition members 50 may be installed at the same height.

The recess 48 may have a height h that can be inserted by sliding the second partition member 50 and the second partition member 50 can be freely shaken after the insertion.

Meanwhile, similar to the grating 100 and 200 according to the above-described embodiment, an anti-slip protrusion 54 may be formed on the upper surface of the second partition member 50. In addition, the upper end of the anti-slip projection 54 is preferably located higher than the upper surface of the first partition member 40 and the upper surface of the rim member 30. Accordingly, since the anti-slip protrusion 54 can play a role, it is possible to effectively prevent slipping.

11 illustrates a method of manufacturing the grating 300.

The grating 300 is provided with a first partition member 40 at predetermined intervals in an internal space consisting of three side members 31, 32, 33, between the first partition member 40 and the first The second partition member 50 is installed by sliding in the direction of the arrow between the partition member 40 and the side members 31 and 33. That is, the second partition member 50 is installed such that the bent portion 52 of the second partition member 50 is inserted into and supported in the recesses 38 and 48. After sliding and installing the second partition member 50, the side members 34 are coupled to the side members 31 and 33.

Since the grating 300 is installed by sliding the second partition member 50, the manufacturing process is simple, and the bent portion 52 of the second partition member 50 is inserted into the recesses 38 and 48. This has the advantage of reducing the number of welding points.
