Description

[Detailed description of the invention] This invention is a type of building fitting that is mainly attached to the entrance door and used when putting various items such as mail and newspapers into the door from outside. , a metal fitting body having an article input port and a fixing attachment part, and a fixed shaft provided along one side of the article input hole on the inner surface side of the metal fitting body to swing the input port by swinging around a fixed shaft axis. A door that opens and closes, and a helical coil that is wound and held around the fixed shaft with one end elastically abutting and locking on the metal fitting main body portion and the other end elastically biasing the door in the closing direction. The present invention relates to a building article inlet fitting made of a spring.

The reason why the door is elastically biased in the closing direction by a helical spring in the above-mentioned article loading opening fitting for buildings is that the loading opening may open unexpectedly due to the influence of wind, making it impossible to see inside from the outside. In order to prevent external air from entering the interior, the conventional fittings of this type have the door 4' of the helical spring 8' closed and biased on the other side, as shown in FIG. Since the end portion 6' is exposed inside so as to be in direct contact with the back surface of the door 4, it is unsightly in appearance, and moreover, it is simply wound and held around the fixed shaft 10'. Since the helical spring 8' can be slid in the axial direction of the fixed shaft 10', the helical spring 8' may be moved depending on the degree to which the rocking operation force is applied to the door 4'. It slides along the fixed shaft 10', and at this time, the other end 6', which is in pressure contact with the back surface of the door 4', rubs the back surface of the door 4', and as a result, the plating, etc. applied for aesthetic purposes, etc. It has the disadvantage that it damages the surface treatment layer of the product, making it look even more unsightly when viewed from inside. Further, due to the sliding displacement of the helical spring 8', a closing biasing force acts on a location eccentric to the door 4', and in this state, the swinging opening and closing of the door 4' causes twisting of the fixed shaft 10', etc. As a result, the opening/closing operation of the door 4' becomes unduly difficult, and the metal fitting itself deteriorates in performance early due to progressive wear of the members.

In view of these circumstances, the object of the present invention is to provide an article loading opening fitting for buildings that improves the visual appearance of the interior through simple structural improvements and can prevent performance deterioration of the fitting itself due to wear and the like as much as possible. There is.

The article inlet fitting for buildings according to the present invention, which has been made to achieve the above object, has a characteristic configuration in which the other end of the helical spring on the door closing biasing side is formed with a hole formed within the wall thickness of the door. It is at the point where it is inserted and locked.

The functions and effects of the article input port fitting for buildings according to the present invention having such a characteristic configuration are as follows.

In other words, by positioning the other end of the helical spring on the door closing biasing side within the wall thickness of the door,
It is possible to eliminate the visual unsightliness caused by the exposure of the other end of the helical spring, resulting in a beautiful finish, and also to reliably prevent the helical spring from sliding in the direction of the fixed shaft axis. This eliminates scratches on the back of the door caused by sliding and prevents loss of aesthetic appearance.In addition, it also prevents twisting caused by the eccentric biasing force caused by the movement of the helical spring, making it easier to use when opening and closing the door. It is possible to prevent rattling and performance deterioration due to wear of fixed shafts and other members as much as possible, thereby maintaining the desired function for a long period of time. Moreover, in order to construct an article input port fitting having such advantages, it is only necessary to add a simple processing step of drilling compared to the conventional method, and it can be implemented advantageously in terms of manufacturing.

Next, embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 1 to 4, the fitting is attached to the building door 11 and fixed to the building door 11 to constitute an article insertion slot fitting for inserting newspapers, mail, etc. into the door 11. The article input port 1 is opened in a plate-like member provided with female screw portions 2, 2, which are an example of fixing attachment portions 2 for fixing the article. A door 4 for opening and closing the article input port 1 is pivotally connected around its upper edge, and further includes a helical spring 8 for elastically biasing the door 4 in the direction of closing the article input port 1. A metal fitting main body 3 is constructed, and the metal fitting main body 3 is tightened and fixed in the mounting opening 12 formed in the door 11 by the tightening force generated by the screwing of the female screw 17 and the male screw 18, and the elasticity of the spring 8 is tightened. The structure is such that newspapers, mail, etc. can be inserted through the article input port 1 while pushing the door 4 open against force.

As shown in FIG. 5A, the pivot connecting portion 13 is composed of a plurality of bulging portions 14 bulging from the upper edge of the article input port 1 on the back surface of the metal fitting main body 3.
... In between, insert the protruding parts 15, 15 protruding from the vicinity of both left and right ends of the upper edge of the door 4, respectively, and in this state, as shown in FIG. 5B, the protruding parts 14... A continuous linear groove 16 is cut into a shape with a wide bottom extending across the parts 15, 15, and then, as shown in FIG. Insert the fixed shaft 1 by caulking the bulges 14...
0 so that it does not fall out, and with one end 5 of the helical spring 8 in contact with the metal fitting body 3, the other end 6 is inserted into the hole 9 formed in the wall thickness of the door 4, The door 4 is configured to be able to swing freely around the fixed shaft 10 and to be elastically biased toward the closing side by the helical spring 8.

Another embodiment of the present invention will be described below.

(a) The helical spring 8 is not limited to the central position in the longitudinal direction of the door 4, but one is provided at each end of the door 4 in the longitudinal direction. Alternatively, a plurality of relatively weak helical springs 8 are provided along the longitudinal direction of the door 4.

(b) A transparent plastic plate is provided on the outer surface of the door 4 to hold a form on which the address and name are written, sandwiched between it and the outer surface of the door 4 so that the address and name can be written on the outer surface of the door 4.

Incidentally, the article input fitting for buildings according to the present invention is not limited to various types of architectural doors 11, but may be attached to sliding sliding doors, or may be incorporated into the outer wall of a building, a fence that partitions the outer edge of a garden, etc.
