Description

[Detailed description of the invention] [Technical field] This invention relates to a stand-type lighting fixture that is used on a desk, especially for studying or working.

[Background technology]

BACKGROUND ART Conventionally, a stand-type lighting device is composed of a base placed on a desk, an arm erected on the base, and a lamp provided at the tip of the arm.

The arm consists of a flexible pipe and an arm cover made of a soft synthetic resin material and wrapped around the flexible pipe. FIG. 6 shows the base end of the conventional arm cover 30. As shown in FIG. As shown in FIG. 7, this base end is fitted into the arm installation recess 34 of the base 31 with the arm cover 30 attached to the flexible pipe 32, and is attached to a threaded portion provided on the end surface of the flexible pipe 32. 33 is inserted into the base 31 and fixed with the nut 35, the end edge 30a is sandwiched between the base end of the flexible pipe 32 and the bottom surface of the recess 34. At this time, the end edge 30 of the arm cover 30
As shown in FIG. 6, a notch 36 is provided in a to prevent the arm cover 30 from coming off.

However, when the stand-type lighting device is lifted by holding the arm cover 30, there is a risk that the arm cover 30 may come off, and the fixation of the arm cover 30 is unstable.

[Purpose of invention]

The purpose of this invention is to provide a stand-type lighting fixture whose arm cover does not easily come off.

[Disclosure of invention]

In the stand-type lighting device of this invention, a locking portion is provided on the inner surface of a recess for arm installation provided in the base, and the locking portion is provided on the outer circumferential surface of the base end portion that is fitted into the recess of the arm cover. The flexible pipe is provided with a locked part that is locked to the flexible pipe, and a bulge that bulges out in the radial direction at the base end of the flexible pipe so that the maximum expansion part faces the rear part of the locked part.

With this configuration, the bulge of the flexible pipe acts as a guide, and the locked part of the arm cover can be smoothly locked to the locking part on the inner surface of the arm installation recess, and the arm cover can be easily locked. It can be easily installed. In addition, after the arm cover is installed, the maximum expansion part of the bulge of the flexible pipe faces the rear of the locked part of the arm cover, which restricts the backward movement of the locked part and prevents it from moving away from the locked part of the recess. Since it is possible to reliably prevent the arm cover from coming off, it is possible to firmly hold the arm cover.

Embodiment An embodiment of this invention will be described based on FIGS. 1 to 5. Figure 1 is a sectional view showing the stand-type lighting fixture of this embodiment, Figure 2 is a plan view of its base, Figure 3 is a partially cutaway front view of the stand-type lighting fixture, and Figure 4 is an arm attached to the base. FIG. 5 is an exploded perspective view showing the method of assembling the same.

As shown in Figures 1 and 3, this stand-type lighting equipment consists of a base 1, an arm 2, a lamp 3, and a shade 4. A ballast 5 is built into the base 1, and an electric cord 6 is connected from the rear. is brought out. Further, a blinking switch 7 is provided at the front of the base 1. This base 1 consists of a lower base 1a that is in contact with the desk top and an upper base 1b that holds the support column 2. The upper base 1b has a clock 8 on its upper inclined surface.
(See Figure 2). Further, an arm erecting recess 11 is provided at the top of the upper base 1b.

The arm 2 includes a flexible pipe 9 and a thin arm cover 1 made of a soft material (polyethylene, etc.) that is wrapped around the flexible pipe 9.
It consists of 0. The arm cover 10 is made by blow molding or the like.

The arm erecting recess 11 of the base 1 has a fourth
As shown in the drawings and FIG. 5, locking portions 12, which are through holes, are bored at two opposing locations on the inner surface.
On the other hand, a locked portion 13 that is a claw that locks into the locking portion 12 is protrudingly provided at the base end of the arm cover 10 . Further, the flexible pipe 9 bulges in the radial direction at its base end, and the maximum expansion part is the locked part 13.
A bulge 14 is formed facing the rear of the bulge 14 , and a fixing screw 1 is attached to the lower end of the bulge 14 .
5 is installed vertically.

Next, a procedure for fixing the arm 2 to the base 1 will be explained. As shown in FIG. 4, first, the threaded part 15 at the lower end of the flexible pipe 9 is inserted into the recess 11 of the base 1, and the threaded part 15 is made to protrude into the base 1 from the hole provided in the bottom of the recess 11. Natsu 16
to fix the flexible pipe 9.
Next, an arm cover 10 is attached to the flexible pipe 9 from above. At this time, when the base end (lower end) of the arm cover 10 is fitted into the recess 11 of the base 1, the locked portion 13 is pushed into the recess 11 by elastic force.
The arm cover 9 is fixed by being locked to a locking portion 12 provided on the inner surface of the arm cover 9.

In this case, even if the arm cover 10 made of a soft material is fitted into the recess 11 in a deformed state due to excessive force, the inclined surface of the bulge 14 of the flexible pipe 9 acts as a guide to prevent the arm cover 10 from being engaged. The stop 13 can be guided into the stop 12 . Therefore, the arm cover 10 can be attached easily and reliably.

Further, even when the lighting device is lifted by grasping the arm 2 after the arm cover 10 is attached, the maximum expansion part of the bulge 14 of the flexible pipe 9 faces the rear part of the locked part 13 of the arm cover 10. This restricts the retreat of the locked portion 13 and reliably prevents the recessed portion 11 from separating from the locking portion 12, so that the arm cover 10 can be held firmly.

In this embodiment, the locking portion 12 is formed of a through hole and the locked portion 13 is formed of a claw, but the locking portion 1
Of course, 2 may be a claw and the locked portion 13 may be a through hole.

[Effect of idea]

According to this invention, the bulge of the flexible pipe acts as a guide, and the locked part of the arm cover can be smoothly locked to the locking part on the inner surface of the arm installation recess. Easy to install. Also, after installing the arm cover,
Since the maximum expansion part of the bulge of the flexible pipe faces the rear of the locked part of the arm cover, the backward movement of the locked part is restricted and it can be reliably prevented from coming off the locked part of the recess. This has the effect that the arm cover can be firmly held.
