Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a handle suitable for a single door such as a steel cabinet.

[Conventional technology]

Conventionally, with handles that are attached to metal decorative plates such as steel cabinets and household refrigerators, it is common to insert the screw shafts provided at both ends of the handles through the decorative plates and tighten the nuts from the backside of the handles. A double nut was used to prevent this.

[Problems to be solved by the device]

According to the handle attaching means as described above, firstly, the nut tightening work is very troublesome, and the screw shaft protruding to the back side of the door may damage the hands and the contents during use. It requires extra work such as cutting off a screw shaft of various lengths, and especially when performing processing such as backing with a heat insulating material on the door body in the refrigerator, the cutting work is always necessary. In addition, the work procedure is determined such that the handle needs to be attached before the lining and the door body is inconveniently uneven due to the handle during the lining work, which is inconvenient.

An object of the present invention is to provide a handle that can improve workability and reduce cost.

[Means for Solving the Problems]

In order to achieve this object, the feature of the present invention is that the handle 3 is made of synthetic resin and
A collar 4 that abuts the outer periphery of the attachment hole of the object to be attached, and a taper surface that protrudes from the center of the collar 4 at both tips
A cylindrical barrel 5 having a stepped circular shape and having an open front end surface for insertion into the mounting hole, and an insertion distal end of the cylindrical barrel 5 for the mounting hole is left on the opposite side of the peripheral wall of the cylindrical barrel 5. By the provided U-shaped or U-shaped groove 6 facing the tip,
An elastic locking portion 7 formed so as to be cantilevered with the distal end portion of the shaft cylinder 5 as a proximal end portion, and the elastic locking portion 7 extends from the proximal end portion to the flange 4 side and outward. A gently-sloping side surface 7a and a receiving surface 7b facing the inner surface of the collar 4 in parallel with each other.
It is in the point of having and.

[Action]

Since the engaging portion 7 on the opposite side of the peripheral wall of the shaft cylinder 5 of the handle 3 is formed so as to be cantilevered at the tip of the shaft cylinder 5, the shaft cylinder 5 is pressed against the mounting hole of the mounting target. Then, they are pressed inwardly against each other against the elasticity of the locking portion 7 and smoothly press-fitted, and after that, they elastically return and the collar 4 is pressed.
It abuts on the receiving surface 7b which is the free end of the locking portion 7 on the side.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a usage state of an embodiment of the present invention. A handle 3 is attached to the open end side of a door body 2 of a cabinet body 1 as an example of an attachment object. The handle 3 is molded from synthetic resin, and as shown in the side view of FIG. 2 and the bottom view of FIG. 3, the collars 4 and 4 are provided at both ends, and the tapered surface 5a is protruded from the center of the collar. The shaft cylinders 5 and 5 each having a circular cross section and an opening front end surface are integrally formed.

The tip end of the shaft tube 5 is defined as a base end portion by a U-shaped or U-shaped groove 6 that faces the tip end portion (downward in the figure) while leaving the tip end portion on the opposite side of the peripheral wall of the shaft tube 5. The locking portion 7 is formed so as to be cantilevered, and the locking portion 7 can be elastically deformed by the elastic force of the material of the handle 3. Furthermore, the locking portion 7
2 is a sectional view taken along the line AA of FIG. 4 and FIG. 2B of FIG.
As shown in the -B sectional view, it has a side surface 7a that gently swells from the base end portion toward the flange 4 side and outward, and a receiving surface 7b that faces the inner surface of the flange 4 in parallel with each other. .

Reference numeral 2a in the figure denotes a front plate (decorative plate) of the door body 2.

According to the handle 3 according to the embodiment having the above-described configuration, the mounting hole (the hole shape is substantially the same as the outer shape of the barrel 5) provided in advance at the handle mounting position of the front plate 2a of the door body 2. When the shaft cylinders 5 at both ends of the handle 3 are pressed against, the shaft cylinder 5 is press-fitted into the mounting hole while the locking portion 7 is deformed along the side surface 7a that is in sliding contact with the hole edge. At the same time, the engaging portion 7 has a receiving surface 7b as a front plate.
Elastic recovery is performed with the collar 4 on the inner surface of 2a and in contact with the surface of the front plate 2a. Therefore, as shown in FIG. 5, the handle 3 is
It is attached with the front plate 2a sandwiched between the receiving surface 7b of the locking portion 7 and the inner surface of the collar 4. This attached state does not fall out unless a special means such as pushing the locking portion 7 into the barrel 5 from the back surface of the door body 2 with a tool is used.

[Effect of device]

Since the present invention is configured as described above, the shaft cylinder 5 can be smoothly press-fitted into the mounting hole of the door body 2, and the elastic recovery of the locking portion 7 at the press-fitting position ensures reliable operation. It can prevent slipping and holding.

In particular, since the locking portion 7 is formed on the opposite side which is a part of the peripheral wall of the shaft cylinder 5, in other words, the locking portion 7 is the portion of the handle 3 to be inserted into the attachment hole of the attachment target. Since it only occupies a part of the peripheral wall of the shaft cylinder 5, the load applied when gripping and operating the handle 3 mounted on the mounting object is also added to the relatively robust shaft cylinder 5 which is not elastically deformed.
The locking portion 7 is less damaged as compared with the case where the entire insertion portion is elastically deformed. Further, since the base end portion of the locking portion 7 is located at the insertion tip end portion of the shaft cylinder 5, in other words, the receiving surface 7b of the locking portion 7 is distal from the insertion tip end portion of the shaft cylinder 5. Since it is not located close to the inner surface of the collar 4 on the insertion tip end side of the shaft cylinder 5, when the handle is handled or when the shaft cylinder 5 is inserted into the mounting hole, the locking portion 7 is somehow.
Since the receiving surface 7b of the above does not get caught and is not forced to fall outward, the locking portion 7 does not deform or break from its base end.
