Description

  The present invention relates to an assembly structure of a case body of a lock box and a dharma receiving seat.

  FIG. 10 of Patent Document 1 discloses a case body that is an example of a case body of a lock box, and a dharma receiving seat that is integrally joined to the inner wall surface of the case body by welding or caulking. FIG. 10 also discloses a cylinder unit, a thumb turn unit, and a dharma (driving body) in terms of those skilled in the art. Details of these members are omitted.

  In Patent Document 2, a horizontally long lock body 1 is passed through a vertically long insertion hole 11 of a front auxiliary plate 10, and a pair of upper and lower leg plates 13 a and 13 b provided on the front auxiliary plate 10 are connected to a pair of upper and lower pairs of the lock body 1. A matter is described in which the front plate 15 and the front auxiliary plate 10 are joined together by caulking means after engaging the protrusions 9a and 9b. Since Patent Document 2 has a structure in which the front plate 15 and the front auxiliary plate 10 are positioned and fixed via the lock body 1 having a pair of upper and lower protrusions 9a and 9b, there is a problem that the number of parts increases.

  By the way, the case body and the like of the lock box are plated. As is well known, plating is a process in which metal is deposited on an object to be processed (metal plate, lock box, etc.) by a chemical or electrochemical reaction. There are various types of plating such as zinc plating, silver plating, nickel plating, tin plating, gold plating, and silver plating.

  As an example of the object to be processed, when the case body (case body, case lid, etc.) constituting the lock box and the inner and outer wall surfaces of the dharma seat are galvanized, Since the dharma seats are formed as separate parts, it is necessary to integrally join them together by welding or caulking. In that case, for example, when the dharma receiving seat is joined to the inner wall surface of the case body by welding means, there is a problem that the galvanized plating or the like is peeled off and the portion is rusted.

  In addition, when fixing the dharma receiving seat to the inner wall surface of the case body using only the caulking means (rigging, caulking protrusion, caulking hole), simply place the dharma receiving seat on the inner wall surface of the case body. However, it is difficult to obtain accurate positioning. In other words, in the combination of parts by simple caulking means using caulking protrusions and caulking holes, the dharma receiving seat is not always fixed at a desired location, and so-called defective products (variation) may occur. There is.

(1) Case element 1
FIG. 1 is a front view showing a state in which a dharma receiving seat 2 is positioned on an inner wall surface 1a of a case element body 1 of a lock box and directly fixed to the case element body 1 (viewed from the inner wall surface). . FIG. 1 shows a “case lid” as an example of a case body 1 that is galvanized as a whole. The case body 1 includes a case body (not shown). Therefore, the same configuration is also obtained when the dharma support seat 2 is caulked and fixed directly to the case body with the dharma support seat 2 placed on the inner wall surface of the case body.

  FIG. 2 is a schematic sectional view taken along line 2-2 of FIG. As shown by the phantom line in FIG. 2, a thumb turn unit (a cylindrical rear end portion of a thumb turn cylinder (a thumb turn cylinder constituting the present embodiment 50) is inserted into an insertion opening (described later) formed in a portion from the rear wall of the case lid 1. 51) When the case body 1 is a case body, a cylindrical rear end (cylinder cylinder) of a cylinder of a cylinder unit (not shown) enters the insertion opening 3. Here, “unit cylinder The “rear end” refers to the rear end of the thumb turn cylinder or cylinder cylinder.

  FIG. 3 is a schematic explanatory view showing a state before the dharma receiving seat 2 is fixed to the case lid 1. The dharma receiving seat 2 is fixed to the inner wall surface 1a of the case body 1 so as to be positioned at the insertion opening.

  FIG. 4 is a front view seen from the inner wall surface of the case lid 1. The configuration of the case lid 1 will be described with reference to FIG. 1a is an inner wall surface of a wide side wall, 1b is a bottom wall orthogonal to the inner wall surface 1a, 1c is an upper wall orthogonal to the inner wall surface 1a, 1d is a rear wall orthogonal to the inner wall surface 1a, and 1e is orthogonal to the inner wall surface 1a. It is a wall. In the front wall 1e, for example, a notch opening 1f for dead bolt (not shown) is formed.

  Therefore, 3 is an insertion opening into which the cylindrical rear end portion 51 of the thumb turn unit 50 enters. This insertion opening 3 is formed in a lantern shape corresponding to the form of the thumb turn cylinder. Also in the case of the outer cylinder of the cylinder lock, since a pair of mounting projections (not shown) are provided at the rear end portion thereof, a lantern-shaped insertion opening is formed at a portion from the rear wall of the case body.

  Reference numeral 4 denotes a single or a plurality of small protrusions. In this embodiment, for example, a total of three small protrusions are formed near the center of the case lid 1 or in the vicinity of the insertion opening 3. These small protrusions 4 can be classified into small protrusions 4a for positioning and small protrusions 4b and 4b for caulking. For example, a small protrusion positioned at the center near the arcuate edge on the right side of the lantern-shaped insertion opening 3 is referred to as a “positioning small protrusion 4a”, and the small protrusions are positioned above and below the small protrusion 4a with a predetermined interval. Can be made into “small caulking projections 4b, 4b”. Of course, the caulking small protrusions 4b and 4b can also be used for positioning. Therefore, a single small protrusion 4 having both positioning and caulking functions may be used.

  Reference numeral 5 denotes one or a plurality of locking portions formed at a site near the insertion opening 3 of the rear wall 1d. In this embodiment, the locking portion 5 is an engagement hole, and a plurality (two in total) are formed in a direction orthogonal to the direction in which the small protrusion 4 projects.

(2) Dharma pedestal 2
Next, a configuration of the dharma receiving seat 2 having a hat-shaped cross section will be described with reference to FIGS. FIG. 7 is a front view of the dharma seat 2. As shown in FIG. 1, the dharma receiving seat 2 is fixed to the inner wall surface 1 a of the case body so as to be positioned in the insertion opening 3 of the case body 1.

  In order to fix the dharma seat 2 to the inner wall surface 1a of the case body, means such as welding, caulking, and fastening can be considered. In this embodiment, the dharma seat 2 is also connected to the case body 1. Similarly, for example, since galvanization is applied to the entire surface, both anchoring and caulking means are employed. In other words, if the welding means is employed, the galvanizing peels off, which causes rusting. Moreover, if only the caulking means is employed, positioning is not easy. Further, if only the engaging means is employed, the dharma seat 2 cannot be firmly fixed to the case body 1 in a desired state.

  Thus, the dharma receiving seat 2 includes a receiving portion 6 having a dharma fitting hole 7, an engaging protrusion 8 protruding from one side facing wall portion 6 a of the receiving portion, and the other side of the receiving portion 6. And positioning protrusions 9 protruding from the opposing wall portion 6b. The receiving portion 6 includes an annular portion having an unnumbered Dalma fitting hole 7, arcuate wall portions formed continuously at the left and right ends of the annular portion, and cutout portions at the upper and lower ends of the annular portion.

  Therefore, the left and right arc-shaped wall portions correspond to the above-mentioned “one side facing wall portion 6a” and “the other side facing wall portion 6b”. The left engaging protruding piece 8 and the right positioning protruding piece 9 extend orthogonally to the opposing wall portions 6a and 6b so as to spread wings from the left and right opposing wall portions 6a and 6b, respectively. A plurality of engaging protrusions 8 a and 8 a are provided at the tip of the engaging protrusion 8, while the positioning protrusion 9 corresponds to a single protrusion or a plurality of small protrusions 4 of the case body 1. Thus, in this embodiment, a total of three engagement small holes 9a and 9b are formed with a predetermined interval in the vertical direction. For example, when the central small protrusion 4a which is one of the small protrusions 4 on the case lid 1 side is used for positioning, the central engaging small hole 9a is correspondingly used for “positioning”.

  In addition, in this embodiment, the positioning protrusion 9 has one or a plurality of small holes 9a and 9b, and pin-shaped small protrusions 4a and 4b projecting from the case element 1 are engaged with the small holes. Match. Therefore, the structure of the caulking means is such that the small protrusions 4b and 4b projecting from the inner wall surface 1a of the case body 1 and the positioning protrusions 9 of the dharma receiving seat 2 are used for the small protrusions. Small holes 9b and 9b, and the small protrusions 4b and 4b are caulked.

(3) Fixing the Dharma Seat to the Case Base 1 As shown in FIGS. 10 to 12, when the Dharma stand 2 is fixed to the case base 1, The piece 8 is engaged with the engaging portion 5 of the case element 1 and the inner surface of the positioning protrusion 9 is located inside the case element 1 via positioning means 4a and 9a provided on the positioning protrusion and the case element. The pin-shaped small projections 4b and 4b engaged with the small projection small holes 9b and 9b of the positioning projection piece 9 are fixed by caulking while being joined to the wall surface 1a in a surface contact state.

  In this embodiment, the case body 1 and the dharma receiving seat 2 are described as being galvanized, but the plating is not limited to galvanization. If plating is possible on the case element 1 or the like, various types of plating are also included. Further, the positioning protrusion 9 has one or a plurality of small holes, and pin-shaped small protrusions protruding from the case body engage with the small holes. At least one of the pin-shaped small protrusions is engaged with the positioning protrusions 9. It is sufficient that one has a positioning function.

  It is used in the field of locks and joinery of the present invention.
