Wheel cover for preventing cable obstruction

The present invention relates to a wheel cover for preventing a cable jam, and surrounds the wheel around the bottom of the leg of the movable object with a hollow cylinder to prevent the cable from being caught between the bottom surface and the gap of the wheel, and also close contact with the bottom surface A cable preventive wheel that prevents the cable from being caught in the gap generated by the cylinder being pushed to one side by the movement of the wheel by forming a skirt-shaped skirt that the cable can be mounted around the lower end of the cylinder. It is about a cover.

In laboratory and emergency room of hospital, research institute, university, etc., a lot of experiment and measurement instruments are installed and used. There are many types of experimental and measuring instruments, but some are fixedly stationary, but they are more compact and more portable.

In addition, various wires such as a power cable, a measurement signal cable, a pressure transmission fluid tube, an illumination wire, and the like are connected to various test and measurement devices, and in the case of a hospital, various tubes connected to the patient are further installed (hereinafter, referred to above). Any wire and tube is collectively referred to as a "cable"). Therefore, various cables are often cluttered on the floor of a laboratory or an emergency room.

By the way, there is no problem in the case of the fixed device and the device, but the small device and the device are often used on a table with casters for securing mobility and ease of storage and installation. Interference between cluttered cables and table wheels is a problem.

In other words, the cable is often inserted into the gap between the bottom surface and the wheels, which greatly reduces the mobility of the table and may cause damage to the cable. In addition, frequent shocks that occur when passing over cables can lead to the failure or error of expensive and sensitive instruments and devices, and can also deteriorate various samples placed on the table. Moreover, if the sample is a dangerous substance, it may cause an unexpected serious accident.

This problem is the same for all moving objects (for example, wheel chairs) with wheels other than a table, and Japanese Laid-Open Patent Publication No. 2002-125786 has been introduced as a prior art for solving this problem.

Japanese Laid-Open Patent Publication No. 2002-125786 calls the invention a "shipment guide mechanism", wherein a shipboard is mounted from a moving body (chair) having a caster attached to a plurality of rotating legs and having a horizontal rotating portion thereon. In drawing out the article, the shipboard guide mechanism extending to the outside of the rotation radius of the plurality of rotating legs is provided on the rotary support to prevent the shipboard article passing through the shipboard guide mechanism from being caught in the caster. .

However, the above prior art is not sufficient for use in a laboratory or emergency room environment, since the number of shipboards that can be guided is limited, and in particular it is impossible to prevent the wheels from being caught in separate cables that do not pass through the shipboard guide mechanism. Has a limit.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the cable cover preventing wheel cover 10 according to the present invention will be described in detail. The present invention is not limited to the embodiments described below, but may be implemented in various other forms, and the present embodiment is not intended to be exhaustive or to limit the scope of the present invention to those skilled in the art. .

First, with reference to Figures 1 and 2 will be described in detail with respect to the first embodiment having a basic configuration of the cable cover preventing wheel cover 10 according to the present invention.

The cable hook preventing wheel cover 10 according to the first embodiment includes a tubular body 100 formed in a hollow so as to surround a wheel around a bottom of a leg of a movable object, for example, a table or a chair; It includes a plate-shaped skirt 200 formed from around the lower end of the cylinder 100 in close contact with the bottom surface.

Figure 2 is a view showing the installation of the cable locking wheel cover 10 of the first embodiment on a table with a wheel, by putting the wheel of the moving body in the hollow cylinder 100 to isolate the wheel and the surrounding space The gap between the bottom and the bottom prevents the cable from being caught.

In particular, the cable hook preventing wheel cover 10 of the present invention is formed in the skirt portion 200 of the plate-shaped extending around the lower end of the cylindrical body 100 in close contact with the bottom surface, which of the cylinder 100 One side is pushed to the wheel to prevent the gap between the bottom surface, and the force (tension) is applied to the cable to prevent the phenomenon that the cable penetrates under the cylinder 100 and caught on the wheel. That is, the skirt 200 formed around the lower end of the cylinder 100 is to prevent the cable from being caught more effectively by preventing the cylinder 100 from being pushed up and making the cable ride up thereon.

It is preferable that the thickness of the skirt 200 is made very thin so as to support the above functions so that the above functions can be effectively exhibited. However, since it is also required to maintain the appropriate strength for durability, it is preferable to make the cross-sectional shape of the skirt 200 into a triangular shape that becomes thinner toward the outer circumferential surface. Of course, the bottom surface of the skirt portion 200 should be in close contact with the bottom surface to prevent the cable from being inserted, it would be more preferable to have a cross-sectional shape that is nearly right triangle (see Fig. 3).

In addition, the upper surface of the skirt 200 may be made smooth so as not to interfere with the cable rise. However, as long as it does not interfere with the movement of the cable, it is also possible to improve the strength by forming a thin rib (not shown) like an umbrella.

Although there is no big limitation in the shape of the cylinder 100, when the cable in contact with the cylinder 100 is pulled or pushed, it can move smoothly on the outer surface of the cylinder 100, the wheel in the cylinder 100 rotates according to the direction of movement If the type is to be preferably formed in a cylindrical shape so as not to catch the rotation of the wheel.

In addition, it is preferable that the size of the cylinder 100 is about the same as that of the wheel of the movable body. This is because if the space within which the wheels can move freely in the cylinder 100 is large, as the impact of the wheel pushing the cylinder increases, the possibility of the gap between the cylinder 100 and the bottom surface also increases. Of course, the sliding phenomenon of the cylinder 100 is greatly reduced by the above-described skirt 200, but if possible, it is more preferable to set the inner diameter and the wheel size of the cylinder 100 to be similar, and the present invention is considered in practice. When commercializing, it is necessary to diversify the size of the cylinder 100 (particularly, the inner diameter size).

In addition, in terms of preventing the cylinder 100 from being pushed, the weight of the cable catching prevention wheel cover 10 is also important and may be as heavy as possible without applying excessive load to the movement of the movable body. In fact, experiments with the model was found to have a weight of about several hundred to 1kg is appropriate, the skirt 200 is preferably made thin because the weight of the cable cover preventing wheel cover 10 is mainly cylindrical ( 100) is adjusted by the thickness and height.

Next, a second embodiment of the cable cover preventing wheel cover 10 will be described in detail with reference to FIG. 3.

A feature of the cable cover preventing wheel cover 10 according to the second embodiment is that the cylinder 100 is composed of two semi-cylinders 100'-1 and 100'-2. This may be cumbersome because the movable body has to be lifted by that amount in order to put or remove the wheels of the movable body in the hollow cylinder 100 as shown in FIG. 2, and in particular, objects such as various devices and devices may be placed on the movable body. When it comes to safety, you have to put things away and work harder.

Accordingly, the first cable 100'-1 for detaching and coupling one cylinder 100 can be mounted and removed without the need for lifting the movable body. And the second semi-cylindrical body 100'-2.

Bonding means are provided on the engaging surfaces of the two semi-cylindrical bodies 100'-1 and 100'-2, respectively, and as shown in FIG. 3, a binding hole 110 having a coupling hole and a wedge shape fitted into the coupling hole. The binding means consisting of the protrusion 200 may be applied. Of course, in addition to the binding port 110 and the wedge-shaped projections 200 it is obvious that a variety of known binding means can be applied.

In particular, each half-cylinder 100 'such that only one binding hole 110 is formed on one side and only the protrusion 200 is formed on the other side of the two mating surfaces of each half-cylinder 100'-1, 100'-2. When the binding means provided at the two engagement surfaces of -1,100'-2 has a complementary line symmetry structure that can be mutually coupled, the first semi-cylinder 100'-1 and the second semi-cylinder 100'-2 It is possible to make the same shape. This is especially helpful for reducing manufacturing costs, especially in the case of using a mold like injection molding. It is not only advantageous for inventory management, but also in terms of maintenance costs since it is not necessary to discard the whole case when only one semi-cylinder is broken. It is advantageous.

And, the cable cover preventing wheel cover 10 according to the third embodiment of the present invention is shown in Figure 4, the characteristics are as follows.

The cable locking prevention wheel cover 10 according to the third embodiment is further characterized in that the upper end of the cylinder 100 is further provided with a fastening portion 130 that is elastically contracted to be in close contact with the outer surface of the movable leg.

This is also the same as the purpose of the second embodiment to reduce the cumbersome work of the mounting and removal of the cable cover preventing wheel cover 10, which is elastically contracted to be in close contact with the outer surface of the movable leg to the upper end of the cylinder 100 It characterized in that the tightening unit 130 is provided.

That is, the third embodiment includes the configuration of the tightening unit 130, so that when it is necessary to remove the mounted cable catching wheel cover 10, the tightening unit (only by pushing the cylinder 100 upwards over the legs) 130 is configured to secure the cable cover preventing wheel cover 10 to the movable leg by the contraction.

Tightening unit 130 may be used alone or in combination with a variety of materials, such as rubber or garter spring that is elastically contracted, it is also possible to be assembled separately from the cylinder 100.

As described above with reference to the drawings illustrated with respect to the wheel cover for preventing the cable jam according to the present invention, the present invention is not limited by the embodiments and drawings disclosed herein, but within the scope of the technical idea of the present invention Of course, various modifications can be made by those skilled in the art.
