2. Description of the Related Art A fitting pulling member such as a crescent or a cam latch handle is used for pulling and locking a fitting to secure airtightness. Generally, a thick steel plate is press-molded, or aluminum is used. It is constructed by casting, and it is said that the strength required for the fitting pulling member depends on the metal material.

[0003]

The fitting-pulling member using the metal material as described above is effective in securing the strength required for the above-mentioned pulling and locking. Generally, this kind of member is used on the indoor side of the fitting. Therefore, it is apt to cause heat transfer of outdoor cold air through the fittings, causing dew condensation due to the difference with the indoor temperature, causing discomfort when opening and closing, or causing water drops to drop.

Also, if there is a slight dimensional error in the installation on the fitting, a metallic sliding contact sound is generated when pulling and locking the door, which may also cause discomfort. On the other hand, like a cam latch handle, for example. When the locking is performed by directly locking the fitting frame, the sliding contact noise is generated and the fitting frame is shaving, and the interior is likely to be exposed and damaged.

Further, there are problems that the design is restricted by the metal material, and the texture tends to make it unsuitable for indoor installation.

The present invention has been made in view of such circumstances, and its problems to be solved are to prevent dew condensation, to prevent sliding contact noise even if there is a dimensional error in installation, and to determine a fitting frame or the like. An object of the present invention is to provide a fitting pulling member that simultaneously satisfies the requirements that it is not damaged and that it can be suitably installed on the indoor side.

[0007]

Use of the above-mentioned reinforced synthetic resin as a reinforced molding part to improve the texture and ensure design flexibility, and outsert molding may be applied to this, and burrs may occur due to outsert molding. On the other hand, in order to eliminate the need for such treatment, a concave narrow groove for concealing a burr that also serves as an accent is installed between the reinforced molding portion and the outsert molding portion. The invention is a synthetic resin outsert molding part in which a reinforcement molding portion of injection-molded reinforced synthetic resin and the reinforcement molding portion are used as a base material and are outsert-molded to be integrally joined. The reinforcement molding part forms a pulling locking part such as a sickle-shaped or projecting piece projecting from the outsert molding part, and the outsert molding part partially covers the reinforcement molding part to reinforce it. It is characterized in that a locking handle portion is formed together with the molding portion, and a concave narrow groove is provided in the joint side edge portion between the reinforcing molding portion and the outsert molding portion in the locking handle portion.

The rotary shaft 5 protruding in a protruding shape is integrally provided and injection-molded.

As a result, the structural strength required for pivotal pulling of the cam latch handle A is mainly shared by the reinforcing molding portion a.

The outsert molding portion b is integrally joined to the joint base portion 7 of the reinforcing molding portion a, and is joined to the edge wall 9 of the handle base portion 6 in the joint curved groove 8 between the outsert molding portion b and the handle base portion 6. The molding tip is positioned at an intermediate position of the edge wall 9 so as to form the concave narrow groove 4 on four sides, and is joined and arranged in a partially covered state on one inner side of the handle base 6.

In this example, the reinforced molding part a is M ×
6 Nylon base is made by directly injection molding nylon pellets containing 50wt% glass fiber. At this time, the mold temperature is 120 ℃ ～ 130 ℃ and the injection welding temperature is 250 ℃ ～ 280 ℃. It is possible to perform molding with glass fibers uniformly dispersed and a smooth surface, and to secure strength equivalent to that of an aluminum casting, for example. Also, the outsert molding part b has a mold temperature of 50 ° C to 60 ° C.

In the example, the crescent body 10 is also provided with a bronze-colored reinforcement molding portion a and a beige-colored outsert molding portion b, and the pulling engagement portion 2 of the reinforcement molding portion a is generally found in this type of crescent. It has a sickle-like shape called a so-called spoon, and has a locking handle 3.
Is formed in a short size, and the pedestal 12 is made slightly thicker, and the closing plate 11 for closing the screw hole 14 is fixed to the screw holes 14 at both ends by snap-in fixing to the pedestal 12. It is provided as a preparation.

The crescent C is also constructed in the same manner as the cam latch handle A, and since the rest is the same as the above example, the same reference numerals are given and the description thereof is omitted.

Although the illustrated example is as described above, in the practice of the present invention, when the reinforcing molding portion is a fiber-reinforced reinforcing synthetic resin containing a glass fiber, the content is 30 wt% or more. The content is preferably 60 wt% or less, and when it is 30 wt% or less, injection molding may cause a molding defect such as a dent or the strength as an attracting member cannot be sufficiently secured. In many cases, this leads to molding defects such as deterioration of surface smoothness.

Further, other fibers such as carbon fiber can be used for reinforcement instead of the above glass fiber. When carbon fiber is used, its content is preferably 20 wt% or more and 40 wt% or less, 20w
When it is t% or less, it becomes a non-uniform dispersion state which is considered to be caused by the specific gravity, and it becomes difficult to secure the strength as the attracting member, and when it exceeds 40 wt%, it is caused by the hygroscopicity of the carbon-based fiber. This leads to insufficient strength, and it becomes difficult to secure the strength as a pulling member as well.

The reinforcement molding portion and the outsert molding portion may have the same color, but as described above, it is preferable to make the color tones different from each other. These color tones are generally injection-molded by additionally adding pigments,
Outsert molding may be performed, but colored coating may be applied if necessary. At this time, the above-mentioned M × 6 of the reinforcement molding part
When using nylon, for example, an instantaneous baking temperature of 240
Baking coating at ℃ can be performed.

As the synthetic resin usable in the present invention, various resins such as vinyl chloride type and polyacetal type may be selected in addition to the above nylon type, but when reinforcing with fibers, the specific gravity is smaller than this. For example, paraffin-based ones must be avoided because they become non-uniformly dispersed due to uneven distribution of fibers, and therefore those having a specific gravity equal to or higher than the above synthetic resin are widely used.

The shape including the pulling engagement portion, the handle base portion, the wall thickness, etc. of the reinforced molding portion may be appropriately set.
On the other hand, the thickness of the outsert molding portion is 3 mm or less, preferably about 2 mm. This is because increasing the wall thickness tends to cause sink marks during outsert molding, resulting in poor appearance.

The recessed grooves are preferably installed so as to extend over the four circumferences of the locking handle, or to appear, for example, on the surfaces facing each other in the longitudinal direction, and the recessed grooves generally have a depth width of 1 mm. Although it is sufficient if the degree is set, it is possible to make it thinner or thicker than the original, and specifically, it may be appropriately interposed and installed according to the exterior design of the fitting drawing member.

In carrying out the present invention including the above, each specific raw material, shape, and structure of the reinforcing molding portion, the outsert molding portion, the pulling locking portion, the locking handle portion, and the concave groove ，
The dimensions, molding method, reinforcing means, additions thereto, specific uses as a fitting pulling member, and the like can be variously modified without departing from the gist of the above-mentioned invention. There is no need to limit it.
