  However, in the case of a configuration that receives the impact given from the indoor door at the door-end side door-contact member as disclosed in Patent Document 1, the entire vertical frame of the opening, that is, the vertical frame of the vertical frame The door will be impacted in the entire range, and the impact will produce a low and heavy sound such as “bang” or “don”.

  Such sound is generated by receiving an impact from the door in a wide range of the vertical frame, and this vibration is also transmitted to the wall continuously arranged from the vertical frame. This is probably because sound is generated (resonates). In addition, vibration is generated in almost the entire door, and this vibration is transmitted to the vertical frame on the hanging side and the wall continuously arranged on the vertical frame, and sound is also generated by the vibration on the hanging side wall. This is thought to be due to (resonance).

  In particular, a low and heavy sound such as “bang” or “don” generated when closing the door is transmitted over a wide range because the wavelength is long. For this reason, the trouble that a door closing sound can be heard from a room away from the same floor or the sound is transmitted to a room on another floor occurs. In particular, in a housing complex such as a condominium, there is a concern that there will be a problem that inconvenience will occur to residents in the upper and lower neighbors and the left and right neighbors, and complaints will occur.

  Therefore, in view of the above problems, the present invention proposes a novel technique regarding a noise reduction measure for reducing a sound generated by an impact when closing a door.

  The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described.

  That is, as described in claim 1, a door stop structure for receiving the door body that is rotated and closed and placing the door body in the frame body, and having a door contact member that is fixed to the frame body side. And the said door stop member is set as the structure arrange | positioned in the partial range of the up-down dimension of the said frame.

  According to a second aspect of the present invention, the door contact member is provided integrally with a latch metal fitting having a latch housing portion for housing a latch protruding from the door body.

Further, as described in claim 3, the frame body is provided with a blindfold material for concealing a gap formed between the frame body and the door body,
Inside the blindfold material, a door stop member fixing portion is disposed,
The door stop member is fixed to the door stop member fixing portion,
The door stop member protrudes from the cutout portion of the blindfold material toward the door end side of the door body.

  According to a fourth aspect of the present invention, the door contact member is made of a buffer material that receives and contracts a load from the door body.

  According to a fifth aspect of the present invention, there is provided a latch receiving bracket having a latch receiving portion for receiving a latch protruding from the door body, and having a door contact member for receiving the door body that is rotated and closed. And the vertical dimension of the said door stop member is set as the latching metal fitting made into the substantially the same as the vertical dimension of the said latching metal fitting.

  As effects of the present invention, the following effects can be obtained.

  That is, in the first aspect of the invention, the impact received from the door body is buffered by the door stop member, and the door stop member is provided in a part of the vertical dimension of the frame body. It is possible to prevent the shock from being transmitted to the entire range. Then, the range in which vibration is transmitted can be reduced, and generation of a low and heavy sound such as “batan” or “don” that can occur when the door is closed can be suppressed.

  Further, in the invention according to claim 2, it is possible to apply a function for fixing the door-holding member to the latch bracket, and it is possible to reduce the number of parts and the number of construction steps. It becomes.

  Moreover, in the invention of Claim 3, since the door stop member fixing | fixed part is hidden by the blindfold material and does not appear in an external appearance, the design property by a blindfold material is securable. In particular, for example, when the prospective surface of the blindfold and the prospective surface of the vertical frame on the door end side are configured with the same design such as wood grain, arrange the door-stop member without impairing the sense of unity. Is possible.

  Moreover, in invention of Claim 4, the shock from a door can be absorbed and relieved by a buffer material.

  In the invention according to claim 5, a function for fixing the door-to-door member can be applied to the latch bracket, and the number of parts and the number of construction steps can be reduced. .

Next, embodiments of the invention will be described.
As shown in FIG. 1, the indoor door 1 is housed in a frame 5 surrounded by a door-end-side vertical frame 2, a suspension-side-side vertical frame 3, and a ceiling-side horizontal frame 4. In addition, blindfolds 6, 7, and 8 are respectively arranged on the expected surfaces of the frames 2, 3, and 4, respectively. The blindfolds 6, 7, 8 are configured to be long, and cover the gaps formed between the indoor door 1 and the frames 2, 3, 4 to block light.

  Further, as shown in FIG. 1, a latch receiving bracket 12 is disposed on the door-end side vertical frame 2 at a position corresponding to the box lock 11 disposed on the indoor door 1 side. A door contact member 20 for receiving the indoor door 1 is provided in the vicinity of the latch receiving bracket 12.

  Further, as shown in FIGS. 2 and 3, the door contact member 20 is formed of a long cushioning material that is long in the vertical direction, and is placed on the surface of the indoor door 1 on the door end side on the indoor door 1 side. A contact surface 21 to be contacted is formed.

  As shown in FIGS. 3 and 4, the door stop member 20 is attached to the support tool 22. The support 22 includes a wall surface fixing portion 22a that is fixed to a wall surface with a screw or the like in a recess 2a formed in the door end side vertical frame 2, and a door contact member fixing portion 22b for fixing the door contact member 20. have. The door stop member fixing portion 22b forms a long-sided face 22c in the vertical direction, and the door-stop member 20 is fixed to the face 22c with an adhesive or the like.

  Further, as shown in FIGS. 3 and 4, the support 22 is concealed and arranged inside the blindfold 6 fitted into the recess 2 a formed in the door-end side vertical frame 2. Thereby, the support tool 22 does not appear in the external appearance, and the designability by the blindfold 6 can be secured. Moreover, the blindfold material 6 is comprised by the hollow square member in the cross sectional view, and has the latching leg part 6a * 6a for latching to the wall surface of the recessed part 2a.

  Further, as shown in FIG. 4, in this blindfold material 6, a part of the door side of the indoor door 1 is cut out, and the door stop member is directed from the cut portion 6 c toward the door side of the indoor door 1. 20 is projected.

  Further, as shown in FIG. 4, in the present embodiment, the dimension W <b> 1 in the width direction of the door contact member 20 (the width direction of the indoor door 1) is configured to be narrower than the dimension W <b> 2 in the width direction of the blindfold 6. As shown in FIG. 2, the prospective surface 6b of the blindfold material 6 is formed continuously so that the designability of the blindfold material 6 can be maintained. However, when the impact received from the indoor door 1 is large and it is necessary to disperse the impact, the door stop member 20 may be set to have a width dimension that protrudes from the expected surface 6b of the blindfold 6.

  In addition, as shown in FIG. 3, the dimension H <b> 1 in the height direction of the door stop member 20 is appropriately designed so that the impact received from the indoor door 1 can be dispersed. However, if the interior door 1 is momentarily closed, if it has a long dimension equivalent to that of the door-end side vertical frame 2 as with the blindfold material 6, this impact is applied to the door-end side vertical frame. Therefore, there is a problem that the vibration is transmitted to the entire wall 2 and the resonance is generated due to the transmission of the vibration to the wall. For this reason, about the dimension H1 of the height direction of the blindfold material 6, it comprises shorter than the up-and-down dimension of the door-end side vertical frame 2, ie, it sets to below half of the up-and-down dimension of the door-end side vertical frame 2, for example. In addition, it is preferable to set the dimension equal to the vertical dimension H2 of the latch receiving metal 12 or the like. Moreover, the door stop member 20 is good also as a structure provided in the location corresponding to the upper-lower-end part position of the indoor door 1, respectively.

  Moreover, as shown in FIG. 4, the door stop member 20 is comprised in the elongate molded product which consists of buffer materials, such as rubber | gum, resin, and a foaming material, Although it does not specifically limit, From the indoor door 1 The latch 13 can be inserted into the latch accommodating portion 12a of the latch receiving bracket 12, and when the indoor door 1 is opened, it is elastically restored to return to its pre-shrinkage. The indoor door 1 is configured to be received even when the indoor door 1 is closed next time when the indoor door 1 is closed. Moreover, the door stop member 20 may be configured to be a long one, and a plurality of block-shaped members may be spaced apart.

  Further, as shown in FIG. 5, with respect to the depth dimension L <b> 1 (expected dimension) of the door stop member 20, the contact surface 21 of the door stop member 20 is the surface of the indoor door 1 in a state where the indoor door 1 is completely closed. It is set so as to be disposed at a position 21B on the side where the indoor door 1 is opened rather than the position 1A. When the indoor door 1 is closed, the indoor door 1 is contracted from the position 21B to the position 21A (state shown in FIG. 4). And when the indoor door 1 is opened again, it sets so that it may return to the position 21B (state of FIG. 5).

  As shown in FIG. 4, in this embodiment, when the indoor door 1 is closed, the indoor door 1 receives a load (elastic return force) from the contracted door contact member 20. In the latch 13 accommodated in the latch accommodating portion 12a of the metal fitting 12, the rotation restricting surface 13b of the latch 13 comes into contact with the vertical wall surface 12b of the latch accommodating portion 12a. For this reason, when opening the indoor door 1, when the latch 13 is pulled to the indoor door 1 side, the rotation restricting surface 13b and the vertical surface 13a rub against each other, so there is a concern that a “rub sound” may be generated. . For this reason, by covering the surface of the vertical wall surface 12 b with the buffer material 14, it is possible to suppress the occurrence of this “rub sound”.

  In addition, as shown in FIG. 4, when the indoor door 1 is closed, the rotation restricting surface 13b of the latch 13 becomes the cushioning material 14 of the vertical wall surface 12b of the latch accommodating portion 12a by the elastic restoring force of the door stop member 20. Contact. As a result, the latch 13 is not displaced in the latch accommodating portion 12a, and the state in which the latch 13 is supported by the latch receiving bracket 12 is maintained. In other words, the indoor door 1 is supported by being pressed so as to sandwich the indoor door 1 between the buffer material 14 and the door stop member 20. Thereby, it can be eliminated that the indoor door 1 flutters (rattles) as a whole.

  Further, as shown in FIGS. 4 and 5, the rotation restricting surface 13b of the latch 13 comes into contact with the buffer material 14 of the vertical wall surface 12b of the latch accommodating portion 12a. Work related to the position adjustment of the wall surface 12b can be simplified. If the vertical wall surface 12 b is not covered with the buffer material 14, the positional relationship between the vertical wall surface 12 b and the rotation restricting surface 13 b of the latch 13 is adjusted by adjusting the position of the vertical wall surface 12 b (position in the expected direction). It is necessary to set. However, by providing the buffer material 14, the indoor door 1 is sandwiched by the contraction of the buffer material 14 and the contraction of the door stop member 20, so that the optimum position in the relationship between the vertical wall surface 12b and the rotation restricting surface 13b. The error from can be absorbed (resolved). Thus, by covering the vertical wall surface 12 b with the buffer material 14, workability during construction of the indoor door 1 can be improved. In addition, regarding the absorption (cancellation) of this error, either the buffer material 14 or the door stop member 20 may be effectively functioned.

  The buffer material 14 shown in FIG. 4 is a well-known rubber, resin, foam material, and the like. For example, use of urethane rubber, CR rubber, EPD rubber, fluorine rubber, silicon rubber, or the like can be considered. Further, in order to improve the slidability (slidability) of the surface, the surface of the elastic material may be coated with PTFE (polytetrafluoroethylene) or the like, or blended with the elastic material. In addition, for the form of coating, another member composed of an elastic material is bonded and fixed (attached) with an adhesive, etc., a solution-like elastic material is applied to the application site, and further, it is welded by pressing while applying heat. It is assumed that various forms are included.

  Moreover, as shown in FIG.6 and FIG.7, it is good also as providing the door stop member fixing | fixed part 61 * 71 for fixing the door stop member 40 to the latching metal fittings 60 * 70. In the example of FIG. 6, a door contact member fixing portion 61 is erected on the strike 62 of the latch receiving metal 60, and the door contact member 40 having substantially the same vertical dimension as the door contact member fixing portion 61 is fixed. It is what. Moreover, the door stop member fixing | fixed part 61 has the long surface 61a to the up-down direction, and is set as the structure to which the door stop member 40 is fixed with this adhesive etc. with respect to this surface 61a.

  Further, in the example of FIG. 7, the strike 72 of the latch receiving metal fitting 70 is extended in the expected direction, and at its end, a wall surface fixing portion 73 for fixing to the recess 2 a of the door-end side vertical frame 2, The door contact member fixing portion 71 for fixing the member 40 is provided. Moreover, the door stop member fixing | fixed part 71 has the long surface 71a to the up-down direction, and makes it the structure to which the door stop member 40 adheres with this adhesive surface etc. with respect to this surface 71a. In the case of the configuration of FIG. 7, the wall surface fixing portion 73 is hidden by a blindfold (not shown) fixed to the recess 2 a of the door-end side vertical frame 2.

  And according to the structure shown in FIG.6 and FIG.7, the function for fixing the door stop member 40 can be applied to the latch metal fittings 60 and 70, and the number of parts can be reduced and the number of construction steps can be reduced. And so on.

  In the above example, the door stop member is composed of only a long molded product. However, as shown in FIG. 8, the plate member 52 is made of a compression spring 51 (shown in the figure) made of a spring, a plate spring, or the like. In the example, the support member 53 is supported via a spring), and the door stop member 50 may be used in this configuration. Further, the contact surface of the plate material 52 with the indoor door 1 may be covered with the buffer material 54. Further, by providing the plate material 55 that conceals the compression spring 51 together with the plate material 52, the compression spring 51 is hidden by the plate material 55, and the expected surface 55b of the plate material 55 and the expected surface 6b of the blindfold material 6 are made of wood grain or the like. According to the similar design, excellent design properties can be ensured. Instead of the compression spring 51, a door contact member made of the above-described molded product may be used.
