Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel door stop operating mechanism. More specifically, it relates to a doorstop operating mechanism that stores the doorstop in a storage recess formed at the top of the door when the door is closed, and causes the doorstop to protrude from the storage recess at the same time as the door is opened. .

Conventionally, a door stop for protecting a door, a door knob, or a wall that they collide with is fixed to the upper end of the door, and always remains protruding from the surface of the door regardless of whether the door is opened or closed. Therefore, the door stop when the door is closed has the disadvantage of detracting from the overall beauty of the door, and this disadvantage is particularly noticeable in high-quality carved wooden doors. Furthermore, such a door stop has the disadvantage that it is located in a position that is difficult for the person opening/closing the door to see, resulting in the risk of hitting people or objects.

Therefore, the inventor of the present invention eliminated the above-mentioned drawbacks and created a completely new function in which the doorstop is housed within the surface of the door when the door is closed, and the doorstop protrudes from the surface of the door only when the door is opened. As a result of extensive research in order to provide a door stop operating mechanism that has the same functionality, we have completed the present invention.

Therefore, the present invention provides a door stop that includes a boss, an arm that projects from the boss, and a buffer member that is fixed to the tip of the arm, and that allows the boss to freely slide in a direction substantially perpendicular to the direction in which the arm projects. and a guide member that guides the door to rotate approximately 90 degrees in accordance with the sliding movement and is arranged in a storage recess formed in the upper part of the door so as to be substantially parallel to the door surface; an elastic member that biases the boss to slide in one direction so that the arm of the door stop projects outward from the storage recess; and an elastic member that slides the boss in the opposite direction so that the arm of the door stop is stored in the storage recess. The gist of this invention is to provide a doorstop operating mechanism that is provided with an abutment member that is pushed in in the axial direction when it abuts against the upper lintel.

Next, the door stop operating mechanism of the present invention will be explained using the drawings. FIG. 1 is a perspective view showing one embodiment of the door stop operating mechanism of the present invention, FIGS. 2a and 2b are sectional views showing different states of the door stop operating mechanism shown in FIG. 1, and FIG. FIG. 1 is a perspective view showing an example of a state in which the door stop operating mechanism shown in FIG. 1 is attached to a door, FIGS. 6 is a perspective view of a main part showing another embodiment of the door stop operating mechanism of the present invention, and FIG. 7 is a sectional view of a main part showing another embodiment of a contact member according to the present invention.

As shown in Fig. 1, the door stop operating mechanism of the present invention is connected to the door hinge (3 in Fig. 3) at the upper end of the door 1.
0) is housed in a housing recess 1a provided on the opposite side. The door stop 3 includes a cylindrical boss 4 and an arm 5 that protrudes from the boss 4 and has a bent tip.
and a buffer member 6 fixed to the tip of the arm 5. The boss 4 is fitted into a guide member 7 fixed within the storage recess 1a in a direction substantially perpendicular to the horizontal direction, so that the door stop 3 is mounted in the horizontal direction. As shown in FIGS. 2a and 2b, a left-handed screw groove 7a having a larger pitch than the effective diameter is formed in the outer peripheral wall of the guide member 7. A thread 4a that can be screwed into the thread groove 7a is formed on the inner peripheral wall of the boss 4.
is guided by the guide member 7 in the vertical direction (arrow A in Fig. 1).
direction), and approximately 90 degrees as the sliding direction increases.
It is guided so as to rotate (in the direction of arrow B in FIG. 1). A coil spring 8 is housed on the lower inner circumference of the boss 4 as an elastic member that biases the boss 4 in the sliding direction. A triangular prism-shaped abutting member 9 is provided at the upper end of the boss 4 via four legs 9a and a ring 9b so as to slide against the rotation of the boss 4 and interlock with the sliding movement of the boss. The abutment member 9 is configured to protrude from the upper end surface of the door 1 when the boss 4 slides upward.

Next, the operation of the door stop operating mechanism constructed as described above will be explained. When the door 1 is open, the boss 4 is pushed up by the urging force of the coil spring 8 until the upper end surface of the boss 4 comes into contact with the inner wall of the storage recess 1a, so that the boss 4 is pushed up into the threaded groove 7a.
It has been rotated to the left along the As a result, the door stop 3 projects almost perpendicularly to the door surface, and the buffer member 6 is located above the upper end of the door 1. Therefore, when the door is opened approximately 90 degrees or approximately 180 degrees as shown by the two-dot chain line in FIG. 3, it hits the attached lintel 10 instead of the opposite wall. On the other hand, when the door 1 is closed, the contact member 9 protruding from the upper end surface of the door 1
At the same time, the boss 4, which is in contact with the ring 9b of the abutting member 9, is also pushed down while rotating about 90 degrees to the right along the thread groove 7a. As a result, the door stop 3 is stored in the storage recess 1a almost parallel to the door surface (Fig. 2b). boss 4
When pressed down, the coil spring 8 is compressed.

Further, in this embodiment, the boss 4 is arranged on the outer periphery of the guide member 7, but as shown in FIGS. Screw thread 14a
It is also possible to insert a boss 14 in which a boss 14 is formed, and to guide the boss 14 so as to be slidable and rotated in accordance with the sliding movement. In that case, it is preferable that the abutment member 19 is rotatably provided with respect to the boss 41, so that the abutment member 19
It is possible to avoid rotational slippage with the upper kamoi,
Frictional force is reduced. Furthermore, as shown in FIG. 5, it is preferable to provide a notch 27a in the guide member 27 so as not to interfere with the arm 5, thereby making it possible to make the whole body compact. Also, as shown in Fig. 6, twist the guide plate 37.
A boss 34 having an engaging part such as a sliding groove 34a or a roller (not shown) guided on both sides or side edges of the doorstop may be adopted, thereby making it possible to manufacture the doorstop storage mechanism at low cost. sell. In that case, when guiding by the side edges, it is preferable to round the side edges to reduce sliding resistance.
Furthermore, the engagement parts of the guide members 7, 17 and the bosses 4, 14 used in FIGS. 2a to 2b and 4a to 4b may be made of materials with low friction such as ball screws.

In each of the above embodiments, instead of using a coil spring, a spiral spring (not shown) is used, in which one end is fixed to the door stop 3 and the other end is fixed to the guide member 7, 17, 27 or the door 1. I can do it. In this case, the biasing direction of the spiral spring is the direction that causes the door stop to rotate in the projecting direction.

Further, the shape of the abutting member related to the present invention may be any shape as long as it has a sliding surface that is pushed down by contact with the upper lintel 11, such as a triangular prism (Figs. 2a to 2b), a hemisphere (Fig. 4a), etc. ~
4b) or hoof shape (not shown)
A shape such as the following can be adopted as appropriate. In those cases, it is preferable to provide a tapered surface (not shown) in the portion of the upper lintel 11 that comes into contact with the abutting member. In addition, the structure of the abutting member is that the abutting member itself is pivoted to a metal fitting (not shown) that holds the door or guide member, that is slidably provided (see Figures 2a and 2b), and that (FIGS. 3a to 3b), a ball 25 rotatably housed in the upper end of the abutment member 29
(FIG. 5), etc. can be selected as appropriate. Further, as shown in FIG. 7, an elastic member 38 biases the abutting member 39 to protrude from the end surface of the door.
may be provided, thereby reducing the load on the coil spring 8. It is preferable that the abutting member and the boss are not fixed together, thereby preventing the reaction force in the door opening/closing direction caused by the contact with the upper lintel from reaching the sliding surface between the guide member and the boss. It can be avoided.

In the embodiment described above, the guide member is provided vertically in the storage recess so that the door stop can rotate in the horizontal direction, but it may be provided in a direction perpendicular to the horizontal direction or in any direction. If the guide member is provided in a direction perpendicular to the horizontal direction and the door stop is arranged so that it protrudes from the door surface by rotating from the bottom to the top, the initial contact force between the contact member and the upper lintel can be reduced. It can be made weaker. Furthermore, it can be installed in a slightly inclined state from a direction perpendicular to the horizontal, so that the tip of the protruding door stop can be made to protrude further above the upper end of the door. In that case, the arm projecting from the boss preferably projects approximately perpendicularly from the door in the extended state of the doorstop.

As mentioned above, the door stop operating mechanism of the present invention is capable of storing the door stop inside the door surface when the door is closed, and allows the door stop to protrude at the same time as the door is opened. This not only improves the appearance of the door but also improves safety, so its practical value is extremely great.
