[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a grip attached to a handrail made of pipe, and is used, for example, for a handrail (with elbow) of a frame made of pipe attached to a simple toilet bowl for the elderly and sick.

[0002]

[Prior art]

 In general, seated toilet bowls, called portable toilets, are often used for the elderly and sick, so some are equipped with handrails and backrests to make them easier to use. There is also a type in which a pipe frame in which a handrail and a backrest are integrally formed on four legs is arranged around the toilet body in consideration of workability of carrying.

In this type of pipe frame, a resin grip is attached to the handrail forming portion for the purpose of obtaining a non-slip effect of the handrail and a good feel.

[0004]

[Problems to be solved by the device]

 By the way, most of the conventional grips used for the handrails of pipe frames of the above-mentioned simple toilets have a cylindrical shape made of resin, and the pipes are mounted in a straight pipe state before processing. Sometimes the procedure is to fit the grip into the handrail part of the pipe, then fix the grip to the pipe by heat processing, then bend or weld the pipe, and finally paint as a finish. Target.

As described above, according to the conventional grip, the work such as bending, welding, and painting of the pipe must be performed after the grip is attached to the pipe, and the workability of each of these steps is poor. In particular, in the painting process, there was a problem in terms of product quality, such as the painting work of the pipe during gripping was difficult, and the finished condition of that part was not good.

The present invention has been made in view of such circumstances, and an object thereof is to provide a resin that can be easily and surely mounted on the handrail forming portion after a series of pipe processing steps are completed. It is to provide a grip made of.

[0007]

[Means for Solving the Problems]

 A structure for achieving the above object will be described with reference to FIGS. 1 and 3 corresponding to an embodiment. The grip of the first invention is made of resin, and the grip body 1 has a substantially cylindrical shape. The inner diameter is smaller than the outer diameter of the mounting pipe 20 by a predetermined amount. Further, the grip body 1 is provided with one slit slit S along the longitudinal direction thereof, and the inner wall surface facing the slit slit S is provided with a predetermined interval along the longitudinal direction of the body 1. At least two hook-shaped stopper members 1a, 1a, which are arranged apart from each other and project toward the center of the cylinder of the grip body 1, are integrally formed. The claws 1b at the tips of the respective stopper members 1a are shaped so as to project only along the longitudinal direction of the main body 1 toward the side away from the central position in the longitudinal direction, and in the opposite directions. The distance L1 between the tips of the two claws 1b, 1b in the longitudinal direction of the main body is determined by the peripheral edge of one of the two holes 20a, 20a formed in the pipe 20 in accordance with the positional relationship between the two claws 1b, 1b. And is set larger than the maximum dimension S1 of the outer distance between the other peripheral edge.

In the grip of the second invention, the grip body 101 has a structure similar to that of the grip body 1 of the first invention described above, and the grip body 101 corresponds to the embodiment shown in FIG. As shown in FIG. 5, at least two stopper members 101a, 101a are integrally formed. Each of the stopper members 101a has a hook shape protruding toward the center of the cylinder of the grip body 101, and each of the claws 101b at the tip of the stopper member 101a extends along the longitudinal direction of the body 1 at the center position side in the longitudinal direction. The distance L2 between the tips of the two claws 101b, 101b facing each other in the longitudinal direction of the main body has a shape protruding only toward the pipe, and the distance L2 corresponds to the positional relationship between the two claws 101b, 101b. It is characterized in that it is set to be smaller than the minimum dimension S2 of the inner distance between one peripheral edge of the two holes 20a, 20a and the other peripheral edge formed in the hole 20.

[0009]

[Action]

 According to the grips of the first and second inventions, since the grip bodies 1 and 101 have a split structure in which the slits S are provided, the bending and welding of the pipe and the painting are performed first. However, the grip body 1, 101 can be fitted into the pipe 20 after these steps are completed. Moreover, by inserting the respective stopper members 1a and 101a into the holes 20a of the pipe 20 at the time of fitting, the claws 1b and 101b of the members 1a and 101a are hooked on the inner surface of the pipe 20, whereby the grip 10, The entire 110 is securely fixed to the pipe 20.

Further, since the inner diameters of the grip bodies 1 and 101 are set to be smaller than the outer diameter of the pipe 20, the grip body 1 and 101, when fitted in the pipe 20, are pushed outward. It is deformed into a shape, and therefore, due to its restoring force, the inner peripheral surfaces of the grip bodies 1 and 101 are in close contact with the outer peripheral surface of the pipe 20 without a gap.

Here, according to the grip of the first invention, the claw 1b of each stopper member 1a is directed toward the end portion (the end portion in the longitudinal direction of the grip body 1) close to the site where the member is arranged. As shown in FIG. 2, the distance L 1 between the tips of the two claws 1b in the longitudinal direction of the main body is more than the maximum dimension S1 of the outer distance between the peripheral edges of the two holes 20a, 20a. As shown in FIG. 2 (a), when the claw 1b portion of the stopper member 1a is inserted into the hole 20a, the entire stopper member 1a is bent and the stopper member 1a is completely inserted. As shown in FIG. 2 (b), the bending of the stopper member 1a is returned to its original state, and the claw 1b is reliably hooked on the wall of the peripheral edge of the hole 20a.

Further, in the grip of the second invention, the orientation of the claw 101b of each stop member 101a and the positional relationship between the tip of the claw 101b and the hole 20a are all opposite to those of the first invention described above. Since it has a structure (see FIG. 2 and FIG. 5 for comparison), the claw 101b is surely hooked to the peripheral wall of the hole 20a by the same action.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. First, the schematic structure of a pipe frame to which the grip of the present invention is attached will be described with reference to FIG.

The pipe-made frame 2 is used in a simple toilet bowl of a sitting type, and as shown in the perspective view of FIG. 3 (a), four legs 21 ... 24, and the handrails 25a, 25b and the backrest 26 are integrally formed on these legs 21 ,. In addition to the above members, the frame 2 is provided with members 27a, 27b and 28a, 28b for locking with the toilet body 1.

Then, the grips 10 of the present invention are attached to the left and right handrails 25a and 25b, respectively. Further, as shown in FIG. 3 (b), holes 20a, 20a for inserting the stopper member 1a, which will be described later, are formed on the upper surfaces of the pipes 20, 20 where the left and right handrails 25a, 25b are formed. There is. Each hole 20a is burred.

FIG. 1 is a view showing the structure of an embodiment of a grip of the first invention, (a) is an external perspective view, (b) is a central longitudinal sectional view, and (c) is an A- of (b). FIG. The grip 10 of this embodiment is a resin molded product, and the grip body 1 is molded in a substantially cylindrical shape, and its inner diameter is set to be slightly smaller than the outer diameter of the pipe 20 on which the grip 10 is mounted. There is. The grip main body 1 has a split structure in which a part of the peripheral wall is divided along the longitudinal direction. The inner wall surface facing the split slit S is fixed at positions near both ends of the main body 1. The members 1a and 1a are integrally formed.

Each of the stopper members 1a is a hook-shaped member that projects toward the center of the cylinder of the grip body 1, and the claws 1b at the tip thereof project only toward each end side of the grip body 1 in the longitudinal direction. It has a shape to put out.

The distance L1 between the tips of the claws 1b and 1b of the two stop members 1a (the tips in the longitudinal direction of the grip body 1) is formed in the pipe 20 on which the grip 10 is mounted, as shown in FIG. It is set to be larger than the maximum dimension S1 of the outer distance between one peripheral edge of the two holes 20a and 20a and the other peripheral edge. Further, the maximum dimension D of the forming portion of the claw 1b of each stop member 1a is set to be equal to or slightly larger than the diameter d of the hole 20a of the pipe 20.

Next, the operation of the embodiment of the first invention described above will be described. First, as a fixing method in the case of combining two parts such as a resin molded product, for example, as shown in FIG. 6, one part 41 is integrally formed with a stopper member 41a having a hemispherical claw part 41b. Incidentally, a method is generally adopted in which a hole 42b is bored in the other part 42, a stopper member 41a is inserted into this hole 42b, and a claw portion 41b at the tip thereof is hooked. According to the above, since the escape amount of the claw portion 41b at the time of inserting the stopper member 41a is small, it is difficult to perform the inserting work. Moreover, when the stopper member 41a is made of a hard resin, the outer peripheral portion of the claw portion 41b is scraped off when the stopper member 41a is inserted, and the catching effect may be reduced.

On the other hand, in the structure of the first embodiment of the present invention, as shown in FIG. 1 (c), there is no claw projection on the circular portion of the stopper member 1a, As shown in FIG. 2 (a), when the pawl 1b portion of the stopper member 1a is inserted into the hole 20a, the entire stopper members 1a, 1a are on the side without the pawl protrusion, that is, in the longitudinal direction of the grip body 1. It bends toward the center side, so that the hook 1b is not caught in the inserting direction, and the stopper member 1a can be easily inserted. Then, when the stopper member 1a is completely inserted, the bending of the stopper member 1a returns to its original state as shown in FIG. 2 (b), so that each claw 1b is securely attached to the wall of the peripheral edge of the hole 20a. Get caught.

Here, in the mounted state shown in FIG. 2B, even if the grip body 1 is displaced in the axial direction, the distance L1 between the tips of the two claws 1b and 1b is two holes. Since it is larger than the maximum outside dimension S1 of 20a and 20a, the claws 1b are not caught.

Next, an embodiment of the grip of the second invention will be described below with reference to FIGS. 4 and 5. First, in this example, all of the orientations of the claws 101b of the respective stop members 101a and the positional relationship between the tips of the claws 101b and the holes 20a are opposite to those of the first embodiment. That is, the claw 101b of each stopper member 101a has a shape protruding only toward the center side in the longitudinal direction of the grip body 101, and the distance L2 between the tips of the two claws 101b and 101b is equal to that of the pipe 20. It is set to be smaller than the minimum dimension S2 of the inner distance between one peripheral edge of the two formed holes 20a, 20a and the other peripheral edge. However, except for these configurations, it is the same as the embodiment shown in FIG.

In this example, as shown in FIG. 5 (a), when the claws 101b of the stopper member 101a are inserted into the holes 20a, the stopper members 1a and 1a are entirely moved outward. When the claw 101b is flexed and the stopper member 1a is completely inserted by pushing in the claw 101b, the stopper member 1a returns to its original state as shown in FIG. 5 (b), and each claw 101b has a hole 20a. Be sure to get caught on the peripheral wall of the. Therefore, also in this embodiment, it is possible to achieve the same effect as the embodiment of the first invention.

In the above-described embodiment of the present invention, the number of the stopper members is two, but the present invention is not limited to this, and when the present invention is applied to a relatively long grip, the grip member is not limited to this. The number of stop members may be appropriately increased according to the length.

Further, the grip of the present invention can be applied not only to the handrail of the frame for a simple toilet bowl, but also to various handrails as long as it is formed of a pipe.

[Effect of device]

 As described above, according to the grip of the present invention, the resin grip body has a split structure in which a part of the peripheral wall is divided in the longitudinal direction, and two grips are provided at a position facing the split slit. Since the hook-shaped stopper member described above is provided, it can be attached to the handrail forming portion of the pipe even after the bending, welding, and painting steps of the pipe are completed. As a result, the workability of the series of steps required to manufacture the handrail is improved, and the finish of the coating is also good. Therefore, the grip according to the present invention is particularly suitable for use in a pipe handrail that has many bending processes such as a handrail for a simple toilet frame.

Further, since the claws of the respective stop members formed on the grip body have a shape protruding only toward the outer side or the center side in the axial direction of the grip body, it is easy to insert them into the holes of the pipe of the handrail forming portion. Moreover, after the grip is attached, the hooking of the stop member by the claw does not easily come off.
